PUBLIC PERCEPTION OF NANO - A SUMMARY OF FINDINGS

2009-10-20T14:17:00.003-05:00

SO I am reviewing all the public perception data on nanotechnology. I had to reread all the studies and select data portions that I will next examine for a 4S presentation at the end of the month. I will post an updated bibliography later.

APPLICATIONS AND PURCHASING BEHAVIOR

Currall, King, Lane, Madera & Turner, 2007
This study examined involving a nationwide web survey in the USA to collect data from 4,542 likely consumers. “Nanotechnology involves human-designed materials or machines at extremely small sizes (atomic or molecular level) that have unique chemical, physical, electrical, or other properties”. This definition was followed by descriptions where they manipulated the level (high or low) of the health or environmental risks and benefits of the four-nanotechnology applications. Respondents were then asked how likely they would be to use such applications on a scale that ran from 1 (extremely unlikely to use) to 7 (extremely likely). To validate the web study, we also conducted telephone interviews with a national random sample of 501 adults. Our results showed that for both the web and telephone samples, respondents did not consider the risks or benefits of nanotechnology independently. Rather, in a pattern that held true for both health- and environment-related applications, the effect of benefits on the use of nanotechnology applications was more pronounced when risks were lower than when risks were high. Thus, our findings showed that public perceptions of nanotechnology are not as simple as previously assumed — risks and benefits are both enmeshed in a complex decision-making calculus. For instance, when the benefits are low, consumers are more concerned about risks than when benefits are high. Although the difference between the responses for high benefit/low risk and low benefit/high risk may seem modest, it is substantial for a survey of this nature. Similarly, the fact that the most positive response (that for high benefit/low risk) is still slightly below the mid-point of the 1–7 scale is not surprising because many respondents had not been exposed to nanotechnology products before the survey.

Siegrist, Cousin, Kastenholz, & Wiek, 2007.
They examined how lay people (N = 153) perceive nanotechnology foods and nanotechnology food packaging, and we examined the factors that influence willingness to buy these products. Participants received some general information about nanotechnology, and specific information about four nanotechnology applications. Overall, participants were hesitant to buy nanotechnology foods or food with nanotechnology packaging. Results suggest, however, that nanotechnology packaging is perceived as being more beneficial than nanotechnology foods. Results further suggest that social trust in the food industry is an important factor directly influencing the affect evoked by these new products.

Cook & Fairweather, 2007.
This study examined intentions of New Zealander to purchase lamb or beef made using nanotechnology. This was a national postal survey (N=565). Most had a positive attitude and intention to purchase (76.6%) and were the type of person who would purchase (self-identity) (49.2%). Most considered they had the support of people whose views are important to them (subjective norm) and few felt an impediment to purchasing (perceived behavioural control). Attitude, subjective norm, perceived behavioural control and self-identity explained a good deal of intention (R2 = 0.64). There was also a strong link between a sum of beliefs about the risks and benefits of the new product and attitude (r = 0.79).

Hart, 2007
In the 2007 survey, adults were asked a series of questions to ascertain their opinions on nanotechnology use in the specific application of food and food-related products. A solid majority (61%) feel that the food supply has become less safe in recent years, with 22% feeling that it has become much less safe in the past five years. One in three adults (29%) feels that the food supply has become safer and 6% feel that it is unchanged in the past five years. If the public is to use food storage products or foods that have been enhanced with nanotechnology, it wants more information about the health risks and benefits associated with nanotechnology in these products. Thirteen percent (13%) of adults say that they would not use food storage products enhanced with nanotechnology and 73% would need more information about nanotechnology used in food storage products before they would use them. Similarly, one in three adults (29%) would not purchase food enhanced with nanotechnology and another 62% need more information to do so. Adults who initially are more aware of nanotechnology are considerably more likely to report that they would use both food storage products and foods enhanced with nanotechnology. Adults who have heard a lot about nanotechnology are nearly three times more likely than adults who have heard nothing, to say that they would use food storage products enhanced with nanotechnology (31% compared with 11%), and are two and a half times more likely to use foods enhanced with nanotechnology (15% compared with 6%).

PUBLIC PREFERENCES AND PERCEPTIONS

Eurobarometer 55.2, 2001
The opinion poll involved over 16,000 people throughout Europe and was carried out in the fifteen Member States of the EU between 10 May and 15 June 2001. They found m any Europeans feel that they grasp topical issues such as "mad cow disease" (76.6%) or the greenhouse effect (72.9%), while some technologies remain very obscure to the public (this is true of nanotechnologies, for instance). Genetically modified food and the Internet come in second place (59.3% and 58.0% respectively), while, finally, three types of technique are less frequently understood: medicines developed from genetic engineering (43.5%), fuel cells (32.7%), and – in clear last place - nanotechnologies (13.8%).

Bainbridge, 2002
Data from October 2001 involved 3909 respondents to an Internet survey questionnaire provide the first insights into public perceptions of nanotechnology. The respondents mentally connect nanotechnology with the space program, nuclear power, and cloning research, but rate it more favorably. In contrast, they do not associate nanotechnology with pseudoscience, despite its imaginative exploitation by science fiction writers.

In response to the first statement asserting that ‘human beings will benefit greatly from nanotechnology,’ fully 57.5% of the 3909 respondents agreed. In contrast, only 9.0% agreed with Bill Joy’s assertion that nanotechnology is ‘threatening to make humans an endangered species.’

Clearly, people who are in favor of nanotechnology also tend to support the space program, nuclear power, and research on cloning. Although opposition to nanotechnology is rare, it correlates with opposition to the three other technologies.

The chief finding of this initial, exploratory study is that science-attentive members of the general public are very enthusiastic about nanotechnology, and a rather large number of ideas about its benefits have already entered popular culture. Over the coming years, social scientists in a variety of fields should employ a diversity of research methods and analytical theories to chart and understand the growing significance of nanotechnology for modern civilization.

Cobb and Macoubrie, 2004
This study used a national random-digit dialed survey data set (N=1536) in spring 2004. More than 80% of survey respondents indicated that they had heard ‘‘little’’ or ‘‘nothing’’ about nanotechnology. For the entire sample, a sizeable percentage (38%) thought risks and benefits would be about equal, and slightly more (40%) predicted that nanotechnology would produce more benefits than risks, while only half that many (22%) said risks would outweigh the benefits. Half (50%) of the high knowledge respondents predicted greater benefits while just 34% of the low knowledge respondents make the same forecast.

Like knowledge, a simple but powerful relationship exists between respondents’ view of science and their predictions of benefits versus risks of nanotechnology. Apparently, respondents to
some degree use their views of science in general as a ‘‘heuristic’’ to construct their perceptions of risks and benefits of nanotechnology. About the same percentages of respondents who expect balanced benefits and risks, or largely benefits, believe science equally solves and creates problems (41%) and largely overcomes problems (47%). Respondents who perceive that science largely creates problems (11%) also predict that risks will be greater.

Unlike answers about benefits, there was no consensus as to which risk is perceived to be the most important one to avoid. The plurality opinion is that ‘‘losing personal privacy’’ is the most important to avoid (31.9%). Although the scenario of self-replicating nano-organisms (‘‘grey goo’’) was identified by the smallest percentage of respondents as the most important risk to avoid, another way to view this result is to be surprised that as many as 12% picked it as the highest risk even though many highly respected scientists consider it an improbable outcome.

Very few Americans report being angry about nanotechnology, and a solid minority reports feeling worried. Indeed, about four out of every five respondents claim not to be worried at all. Conversely, about 70% said they are very or somewhat hopeful about nanotechnology.

Less knowledge about nanotechnology is associated with far less hopefulness than more knowledge. Almost 27% of low knowledge respondents reported not feeling hopeful about nanotechnology, but just half that percentage (13%) of high knowledge respondents said they feel that way. Conversely, while just 27% of low knowledge respondents claim to be very hopeful, 44% of high knowledge respondents say the same thing.

A majority of Americans reports low trust in business leaders within the nanotechnology industry to protect them from potential risks. Slightly more than 60% of respondents said they had ‘‘not much trust’’ in business leaders’ ability or willingness to minimize risks to humans. Although a sizeable percentage claimed to have ‘‘some’’ or ‘‘a lot’’ of trust (40%), fewer than 5% of the sample said they had ‘‘a lot’’ of trust. The amount of trust respondents have is not significantly related to knowledge about nanotechnology, but it is strongly associated with perceptions of specific potential risks and benefits. Less trust also results in more respondents claiming that risks will outweigh benefits.

According to the data in, Prey has a counter-intuitive effect on perceptions of risks versus benefits. A whopping 63% predicted that benefits of nanotechnology would exceed the risk if they were exposed to Prey, compared to just 38% is they weren’t exposed to it.3 Likewise, just
13% thought risks would surpass the benefits if they were exposed to Prey, while 23% said this if they weren’t. Even though the descriptive data made it appear that Prey did not influence trust, the regression analysis indicates that exposure to the novel significantly correlates with less trust. Those exposed to Prey are less trusting of business leaders.

BMRB Social Research, 2004
Questions were placed on BMRB’s face-to-face omnibus survey from 8-14th January 2004. The questions were asked of a representative sample of 1005 adults aged 15 or over in Great Britain. All interviews were conducted in-home.

The omnibus survey results showed that three in ten respondents said they had heard of nanotechnology (29%). Awareness was higher among men (40%) than women (19%). Awareness was slightly lower for older respondents, falling from around a third for those aged under 55, to a fifth (20%) of those aged 65 or over. There was also a clear pattern by social grade, with awareness peaking at 42% for ABs (upper socio-economic classification) and falling to 16% of Des (lowest socio-economic classification).

When asked what they thought nanotechnology was in the omnibus survey, a third said they did not know – often saying that they had “just heard of it”, but didn’t know what it was. This reduces the proportion who had heard of nanotechnology, and were able to give some definition (however accurate) to one in five (19%). This accentuates the difference by gender – women were more likely than men to say they did not know what nanotechnology was meaning that, in total, 30% of men and only 10% of women had some idea of what nanotechnology might be.
The youngest and oldest respondents were most likely to say they did not know what nanotechnology was. This means that those aged 35-54 were most likely to be able to give some definition of nanotechnology (around a quarter).

The most common definitions of nanotechnology centered on miniaturization, or technology on a very small scale. In total 46% of those who had heard of nanotechnology gave an answer in this vein (14% of all respondents). Another frequent approach to defining nanotechnology relied on a particular application such as computing, electronics, or medicine. This type of answer was given by 30% of those who had heard of nanotechnology (9% of all respondents). The majority (two thirds) felt that nanotechnology would make things better in the future, with very few saying it would make things worse. Consistent with the tendency to define nanotechnology by its applications, 13% said it would depend on what it was used for.

Cobb, 2005
This survey of public attitudes about nanotechnology was a random digit-
dialed survey of adults eighteen years or older in the continental United States between late March and early April of 2004 (N = 1,536). Respondents were randomly assigned to one of ten experimental conditions: an oversampled control group (N = 330) or one of nine unique framing conditions about the risks or benefits of nanotechnology (N = 134, each). Respondents in all conditions, even the control group, heard a brief, objective description about nanotechnology. Next, respondents in each of the nine framing conditions heard a distinct way of framing nanotechnology. In six of the experimental conditions, respondents listened to one-sided frames. Three of the one-sided frames were “pro” and three were “anti” nanotechnology. The remaining three conditions are two-sided frames that pit each of the preceding “pro” frames against their equivalent antinanotechnology frames. Substantive questions about nanotechnology were then asked immediately following the frames.

One-sided frames are consistently effective, but only when they identify specific risks or benefits about nanotechnology. Neither frame that promoted a particular version of the merits of science alone—conservative humanism or cornucopian—was influential. All four additional one-sided frames, however, created different perceptions about the balance between risks and benefits. Both frames including health risks and multiple kinds of risks about nanotechnology increased the percentages believing that risks will exceed or be equal to benefits. Similarly, both cornucopian frames that included specific benefits about nanotechnology resulted in more people expecting the benefits to surpass the risks. Interestingly, risk frames never resulted in a plurality of respondents believing that the risks of nanotechnology would be more likely than its benefits. Instead, respondents in the risk frames conditions were simply more skeptical about potential benefits. Conversely, framing nanotechnology as beneficial resulted in an actual majority of respondents in the health benefits condition saying that benefits would prevail, and a solid plurality in the multiple benefits condition saying the same thing. As expected, opinion change was less likely to occur when respondents were in one of the two-sided framing conditions. Respondents’ perceptions about nanotechnology were significantly different in just one of these three two-sided framing conditions. In this one case, perceptions of risks unexpectedly increased when respondents heard both the conservative humanist and cornucopian frames. This appears to be a statistical anomaly because neither of these particular frames was associated with significant opinion change when they were one sided. Overall, then, the general pattern of results for two-sided frames is consistent with the claim that framing effects tend to occur because respondents are exposed to just one side of a debate.

Special Eurobarometer 224, 2005
Over 32,000 interviews were conducted face-to-face in people’s homes in their national language in early 2005. The countries surveyed include the twenty-five Member States. Nanotechnologies receives by far the lowest rate of interest among the suggested items, with a mere 8% mentioning interest in developments of this field. As for “Genetics” we can note that the higher the education level, the more interest is perceived as well. This is also the case for “Nanotechnologies” where the highly educated show clearly more interest than those with a lower level of education. Finally, we can say that ‘nanotechnologies’, although remaining at the lowest rate among all the proposed items, has seen its score more than double since 2001 (from 4% to 9%), and is perhaps slowly becoming a wider theme of interest for Europeans.

Gaskell, Ten Eyck, Jackson & Veltri, 2005
The article drew from the Eurobarometer survey. Fieldwork was conducted in September and October 2002 (N=15,000). The US survey is a random probability telephone survey with fieldwork conducted between December 2002 and February 2003 (N=850). This survey also examined media coverage. While interesting, it is not relevant to this research project.

Asked whether nanotechnology will improve our way of life, 50 percent of the US sample said “yes” and 35 percent say “don’t know.” The European figures are almost the mirror image, 29 percent saying “yes” and 53 percent saying “don’t know.” People in the US are also more optimistic than Europeans about eight more familiar technologies. Overall, while more Europeans are likely to suspend judgment about nanotechnology and opt for a “wait and see” position, people in the US are more likely to take an optimistic stance on this, as yet, unknown technology.

Einsiedel, 2005
Interviews were conducted by telephone during a three-week period in January 2005. Fieldwork was carried out by a commercial research firm. A sample size of 1200 randomly selected adults was used in the US and a random sample of 2000 was used in Canada.

Awareness of NT was gauged on three dimensions: whether respondents were familiar with, had been exposed to, and had discussed the technology. US respondents were more likely to indicate familiarity, with a significant minority – four in ten – saying they were somewhat or very familiar. Among Canadians, about a third had the same view. About four in ten in both countries said they had had exposure from reading, seeing or hearing something about the subject. Only a quarter in both countries said they had discussed the subject with anyone.

Given the limited awareness and familiarity, there are indications that publics in both countries are giving the technology the benefit of the doubt, with at least half suggesting they see moderate risks but substantial benefits. The cautiousness Canadians have for this technology is reflected in their judgment about its moral acceptability, with almost the same numbers saying they find NT morally acceptable as those maintaining it was morally questionable. Canadians are less optimistic than Americans about the economic benefits they project for this technology, with close to six in ten expecting modest or no significant benefits. Only about half of U.S. respondents share this view. As for expectations of major benefits, four in ten U.S. respondents (42%) and slightly over a third of Canadians (36%) expected “major benefits” to flow from this technology. The remainder of the study examined confidence in oversight and trust in regulators.

Scheufele & Lewenstein, 2005
In the fall of 2004, we conducted a representative national telephone survey with a sample size of N=706. The cooperation rate (based on standard definitions developed by the American Association for Public Opinion Research) was 43% (AAPOR definition CR-1).

Fifety-five (sic) percentage of all respondents who indicated that they were aware of the issue of nanotechnology expressed overall support for nanotech, compared to only 28% of the unaware group. This is compared to 52% support and 48% opposition in the total sample. Similarly, 49% of the aware respondents supported more increased financial support for nanotech research, compared to 22% of the unaware group. In the total sample, the breakdown was 42% in favor of increased funding and 58% opposed to increased funding. About 35% of frequent readers of science news in newspapers for example, indicated that the benefits of nanotechnology outweighed the risks. Among respondents who do not read science news frequently, only 25% thought that the benefits outweighed the risks.

Their findings confirm previous research that suggests that people form opinions and attitudes even in the absence of relevant scientific or policy-related information. In fact, our data show that cognitive shortcuts or heuristics – often provided by mass media – are currently a key factor in influencing how the public thinks about nanotechnology and about its risks and benefits, and in determining the level of support among the public for further funding for research in this area.

Sheetz, Vidal, Pearson & Lozano, 2005
A multiple-choice questionnaire was distributed to 978 students and staff (over
18 years old and not related to science and engineering fields) within the University of Texas Pan American (UTPA). The results were grouped into three categories: (1) those who had never heard of nanotechnology; (2) those who had heard of nanotechnology but did not know what it was or could not define it correctly; and (3) those who knew about nanotechnology. The percentage of respondents who knew what nanotechnology was 17%. The percentage of people who had at least heard about nanotechnology was 45%. When respondents were asked if they would like to know more about nanotechnology,
76% said ‘yes’. Even in a community with only 17% awareness, there was interest in the science. Respondents were asked about possible nanotechnology application(s) they might support. People are more inclined to support health issues: 79% supported better ways to diagnose and cure diseases; 59% support cheap and renewable sources of energy; 37% would like to see the development of super-tiny electronics.

They uncovered findings associated with sources of information and trust. The dominant source of information was the mass media, such as television, movies, and magazines (61%) and that ‘scientists and engineers can be trusted to make decisions in the best interest of the general public (80%).

Lee, Scheufele & Lewenstein, 2005.
This study utilized a national survey data set collected in fall 2004. It found, only science media use had a direct influence on general support for nanotechnology and the effects of formal education on general support for nanotechnology were largely mediated by science media use. The effect of level of religiosity was mediated by affective variables, such as trust in scientists and negative emotion toward nanotechnology. With respect to the main effects of cognitive and affective factors, we found significant positive links between knowledge about science in general and trust in scientists and general support for nanotechnology. Negative emotion toward nanotechnology was negatively related to general support for nanotechnology, even after all other controls were entered in the model (see Cobb and Macoubrie, 2004). With regard to the explanatory power of trust, however, trust in scientists seems to be a better predictor of general support for nanotechnology than science knowledge in our models. Knowledge about nanotechnology and negative emotion toward nanotechnology had a significant interaction effect on general support for nanotechnology as the criterion variable. In line with previous research on public perceptions of risk about emerging technologies, females showed a higher level of risk perceptions
Similar to the OLS model for general support for nanotechnology, the influences of religiosity were largely mediated by other affective variables in the model. Also, consistent with previous research, science media use had a negative and robust effect on perception of risks versus benefits. Knowledge about science in general and trust in scientists showed a negative relationship with risks-versus-benefits perceptions, whereas negative emotion was positively related. However, the relationships for affective variables were particularly interesting: (1) individuals who showed higher levels of trust in scientists were likely to perceive more benefits than risks, and (2) individuals who showed higher levels of negative emotion toward nanotechnology were likely to perceive more risks than benefits. While there was a main effect between negative emotion toward nanotechnology and perception of risks versus benefits of nanotechnology, the interaction between negative emotion toward nanotechnology and knowledge about nanotechnology was also significant. This suggests that knowledge about nanotechnology had a significantly stronger effect on risks-versus-benefits perceptions if individuals also had low levels of negative emotion toward nanotechnology

Macoubrie, 2006
Participants (N = 152) self-assigned themselves randomly to the experimental conditions, without knowledge of doing so, by choosing group meeting times that fit their schedule. A professional firm conducted recruitment in the selected sites of St. Paul MN, San Diego CA, and Raleigh-Durham NC. A comparison shows that as in the national survey sample (N = 1536 (Cobb and Macoubrie, 2004)), 95 percent of the present study’s participants had heard almost nothing or a little about nanotechnology. As well, less than 1 percent of the study participants had read Prey or Swarm (science fiction novels featuring nanotechnology predators that might lead to a negative view of nanotechnology), again as with the national sample.

These results may be useful in risk communication about nanotechnology. At this emergent phase of nanotechnology development, creating better ways to predict those risks and protect against them might go far in restoring public trust of government and the US medical industry. “Selling” nanotechnology without knowledge of long-term risks does not seem likely to counter concerns grounded in past experience, and does seem likely to repeat the error of the genetically modified foods industry, pressing ahead while ignoring public concerns. The majority of respondents in this study were at once concerned about known areas of risk, still clearly interested in the benefits (to be explicated separately and discussed in detail elsewhere), excited about the potential of nanotechnology, but concerned about its employment and other social effects, concerned that over-regulation could negate the potential, and concerned that if other countries are developing nanotechnology, the United States should not fall behind. They scorned “trivial” applications (such as cosmetics and wrinkle-free fabrics), and wished to encourage important applications such as in water quality, medical uses to reduce human suffering, and applications that would alleviate distress in developing countries. Yet it seems unlikely that either “education” or image campaigns can easily mitigate a strong lack of trust, linked in the public mind to decades of past failures to consider downstream risks.

Scheufele, Corley, Dunwoody, Shih, Hillback & Guston, 2006
The first data source was a general population telephone survey of 1,015 US adults; the second data source was a mail survey of 363 nanotechnology scientists and engineers. The fieldwork was conducted from May to July 2007 for the public opinion survey, and from May to June 2007 for the scientist survey.

A comparison between two recent national surveys among nanoscientists and the general public in the US shows that, in general, nanoscientists are more optimistic than the public about the potential benefits of nanotechnology. However, for some issues related to the environmental and long-term health impacts of nanotechnology, nanoscientists were significantly more concerned than the public.

The relatively low levels of attention that health and environmental risks of nanotechnology have received in mass media, therefore, provide industry and university scientists working in this area with a unique opportunity to take a leadership role in engaging the public in a meaningful dialogue about nanotechnology. In fact our research shows that industry and university scientists are among the handful of groups the public trusts the most for information about nanotechnology — much more than governmental bodies, regulatory agencies and news media. Nanotechnology may, therefore, be one of the first emerging technologies where academia and business have the ability to reach out directly to a public who trusts the information they provide. Ironically, nanotechnology may also be the first emerging technology for which scientists may have to explain to that public why they should be more rather than less concerned about some potential risks.

Fujita, 2006
This survey undertaken in late 2004 involved 1011 in the Tokyo area. The population was well educated but not technological professionals. 44% indicated an interest in science and technology and 50% perceived nanotechnology would improve their lives. 55.2% claimed they had heard about nanotechnology frequently or from time to time. 85.6% hoped nanotechnology would contribute to the developments in medicine and health care, 30% felt it would have a positive impact on the Japanese economy, and 80.4% hopes it would help alleviate environmental problems. 71% claimed they learned about nanotechnology on TV news and programs and 58% from newspapers. In general, 88% saw positive benefits while 54.5% indicated some concerns. Among them 60% were concerned about safety, 79% were concerned about unexpected outcomes, and 49% were concerned about morality.

Lee & Scheufele, 2006
Using national telephone survey during fall 2004 data (N=706 w a 40% cooperation rate), we examine the pathways between different types of media use and attitudes toward nanotechnology, particularly potential mediating roles of nanotechnology knowledge and deference toward scientific authority. People relying on newspapers and the Internet for science information report higher levels of nanotechnology knowledge, while respondents using science TV showed higher levels of deference toward scientific authority.

We found that Web science use was indirectly related to public attitudes toward nanotechnology through knowledge about nanotechnology. However, the direct relationship between Web science use and attitudes toward nanotechnology was not statistically significant, indicating complete mediation.

We found that television science use is associated with public attitudes toward nanotechnology through deference toward scientific authority, whereas the influences of newspaper science use are at least partly mediated by nanotechnology knowledge. It should be noted that despite the concern over sensational journalistic practices, newspaper science use positively affects people's science knowledge. In contrast, television science use was not significantly linked to nanotechnology knowledge. At this point, mass media coverage of nanotechnology is minimal, and, therefore, people seem to rely upon alternative media (i.e., the Internet), through which they can actively search for additional and in-depth information regarding nanotechnology.

Priest, 2006
A January 2005 telephone survey of 1200 people in the U.S. and 2000 Canadians provides a snapshot of current North American opinion regarding nanotechnology at this crucial early point in its emergence from the laboratory to the arena of public discourse and public understanding.

Unsurprisingly, familiarity remains low, with 57% of those in the U.S. and 64% of Canadians indicating they are ‘‘not at all familiar’’ or ‘‘not very familiar’’ with nanotechnology.

Data from the 2005 U.S.–Canada telephone survey on which the analysis being reported here is based indicate 46% of respondents in the U.S. and 39% in Canada think nanotechnology ‘‘will improve our quality of life in the next twenty years,’’ 13% in each country think it will ‘‘have no effect,’’ and 6% in the U.S. and 5% in Canada think it will ‘‘make things worse.’’ Fully 35% of those in the U.S. and 43% of Canadians do not know or declined to answer. However, of those who reported they were ‘‘very’’ or ‘‘somewhat’’ familiar with nanotechnology – about 38% of the respondents for both countries combined, higher than the 29% reported in the earlier UK Royal Society study who had ‘‘heard of’’ nanotech – 64% answered that it ‘‘will improve our quality of life.’’ Among the 6% who say they are ‘‘very’’ familiar, this rises to 76%.

Of 600 people in the U.S. who were asked whether or not ‘‘nanotechnology research has been considerate of my interests, values and beliefs,’’ 49% said ‘‘yes’’ and 38% said ‘‘no.’’ Of 1000 people in Canada asked the same question, 48% said ‘‘yes’’ and 43% said ‘‘no.’’ Among ‘‘true believers’’ in both countries combined, 70% said ‘‘yes’’ and only 21% said ‘‘no.’’ At the other extreme, among ‘‘ethical populists’’ only 25% said ‘‘yes’’ but 66% said ‘‘no.’’ Overall, only 50% of respondents in the two countries combined answered ‘‘yes’’ to this question, with a clear pattern of variation among the ‘‘publics’’.

Hart, 2006
The study surveyed a general population (N = 1-14) early fall 2006 and major component of the survey involved data collection on familiarity and approval ratings for government agencies.

Public awareness of nanotechnology is increasing, as the proportion of Americans who say they have heard a lot or some about nanotechnology has nearly doubled from 16% in 2004 to 30% today. One in ten Americans say that they have heard a lot about nanotechnology, and 20% say they have heard some. However, fully 69% recall hearing just a little or nothing about nanotechnology. Indeed, a large segment of the public, 42%, has heard nothing at all about nanotechnology.

When asked for their unaided evaluation of the trade-offs between the risks and benefits of nanotechnology, more than one-third (35%) of the public believes that the risks will outweigh benefits, 15% think the benefits will outweigh risks, and 7% say that the risks and benefits will be about equal. However, a large segment of the public has no initial impression of nanotechnology, with 43% indicating they are not sure.

Individuals who have heard more about nanotechnology are more likely to think that the benefits will outweigh the risks. As familiarity with nanotechnology decreases, concern about risks increasingly takes priority over the potential benefits. Of those who have heard a lot about nanotechnology, 46% feel that benefits will outweigh risks and 37% feel risks will outweigh benefits. Of those who have heard some about nanotechnology, 32% feel that benefits will outweigh risks and 42% believe risks will outweigh benefits. For those who have heard just a little, 13% feel that benefits will outweigh risks and 52% feel risks will outweigh benefits. For those who have heard nothing at all about nanotechnology, only one-quarter (26%) are willing to make a judgment about the trade-offs between risks and benefits—2% feel benefits will outweigh risks, 20% believe risks will outweigh benefits, 4% believe risks and benefits will be equal, and a large majority (73%) are not sure.

Hart, 2007
This study surveys a general population (N=1014) early fall 2007 and major component of the survey involved data collection on familiarity and approval ratings for government agencies.

Three-quarters (76%) of adults who heard nothing at all about nanotechnology reported they were not sure about the risks-versus-benefits tradeoff and another 17% in this group reported that risks and benefits will be about equal. Only 7% of adults who are completely unaware of nanotechnology assess whether the risks would outweigh benefits or vice versa

A majority of the public is too uncertain about nanotechnology to make any judgment about its risks and benefits. Without having been provided any information about nanotechnology, respondents were asked to assess the trade-offs between the risks and benefits of nanotechnology.

About half (51%) of adults had no opinion either way, indicating that they are not sure about the risks-versus-benefits tradeoff. Another 25% report that they think the risks and benefits will be about equal, 18% say that benefits will outweigh risks, and 6% say risks will outweigh benefits. In comparing these results with the 2006 poll, there is a slight increase in the proportion of adults who think that benefits will outweigh risks, increasing from 15% in 2006 to 18% today. The proportion of adults who say that risks will outweigh benefits remains about the same, with 7% saying the risks will outweigh the benefits in 2006 and 6% saying that today.

A strong relationship exists between awareness of nanotechnology and the opinion that benefits will outweigh risks. More than half (51%) of adults who have heard a lot about nanotechnology believe that the benefits will outweigh the risks, as compared with 42% of those who have heard some, 17% of those who heard just a little, and 3% of those who heard nothing at all. Not surprisingly, as awareness decreases, so does willingness to make a judgment at all about the risks-versus-benefits tradeoff of nanotechnology.

COMPARING 2007 RESULTS TO 2006 RESULTS

The proportion of adults who have heard a lot or some about nanotechnology actually decreased slightly in the past year, from 30% in 2006 to 27% today. Only 6% say they have heard a lot about nanotechnology, one in five (21%) has heard some, 29% have heard just a little, and two in five (42%) adults have heard nothing at all about it. Men, especially those under age 50, as well as individuals with more education and higher incomes are more likely to have heard at least something about nanotechnology. In fact, 39% of adults with a college education and 40% of those with household incomes exceeding $75,000 report hearing some or a lot about nanotechnology. These relatively high levels of awareness among those with more education and higher incomes are very similar to the 2006 poll findings. Those who have heard anything at all about the technology were asked specifically where they heard about it. The most frequently cited sources include: news programs and the newspaper; television, with the Discovery Channel and science channels frequently referenced; magazines, journals, and scientific publications; the Internet; and friends or family.

EXPERIMENT

Adults were read the following information about nanotechnology, and then asked again to decide whether the benefits of nanotechnology will outweigh the risks, the risks will outweigh the benefits, or the risks and benefits will be about equal. Upon being read this information, 30% of adults report that the benefits will outweigh the risks, a 12-point increase from their initial impression, 22% say the risks will outweigh the benefits, a 16-point increase, and 37% say the risks and benefits will be about equal, a 12-point increase. One in 10 (11%) remains unsure.

Burri & Bellucci, 2007
The Swiss focus groups on nanotechnology took place in September 2006. They had the form of a so-called publifocus, which is an instrument developed by the Swiss Centre for Technology Assessment (TASwiss) to facilitate public discussion of emerging technologies. The Swiss focus groups on nanotechnology showed that citizens today, at least in the Swiss context, are neither reluctant toward nanotechnology nor highly enthusiastic facing the potential environmental and health risks the emerging technologies might imply.
Nevertheless, citizens hope for economic payoffs through the creation of jobs in the nano industry, and are optimistic in regard to the benefits nanotechnology might bring to innovations in medical treatment, environmental activities, and daily life in the future.

Nerlich, Clarke & Ulph, 2007
This study involved responding to a hypothetical health treatment scenario and a Likert scale preference method with classroom setting samples of undergraduate students (N=434) in late 2005 and early 2006 in England. Overall then, the young people in this study seemed less excited, and less bothered, by the advent of nanotechnology — at least in this field of application — than we thought they might be. There was, however, a gender difference, not so much in relation to the forms of treatment, nano versus traditional, but in the overall excitement for novel treatment demonstrated by male participants rather than female participants. This tallies with research into gender differences in public attitudes to science and technology in general and nanotechnology in particular.

Siegrist, Keller, Kastenhol, Frey & Wiek, 2007
Inexpert (N = 375) and expert (N = 46) perceptions of twenty (20) different nanotechnology applications and three non-nanotechnology applications were examined via survey under taken in the German-speaking part of Switzerland. Participants were asked to rank hazards from asbestos to skiing using ten five-point scales using modified Sandman’s dichotomies (add source) including voluntariness, control, trust, etc.

Analyses of aggregated data suggested that perceived dreadfulness of applications and trust in governmental agencies are important factors in determining perceived risks. Similar results were observed for experts and laypeople, but the latter perceived greater risks than the former.
Analyses of individual data showed that trust, perceived benefits, and general attitudes toward technology influenced the perceived risk of laypeople. In the expert sample, confidence in governmental agencies was an important predictor of risks associated with nanotechnology applications. Results suggest that public concerns about nanotechnology would diminish if measures were taken to enhance laypeople’s trust in governmental agencies.

Even though we observed substantial mean differences for the various applications, the ratings were highly correlated. In other words, some people assess all nanotechnology applications positively, whereas others assess nanotechnology in a generally negative way. Therefore, we could examine the question of why different persons perceive nanotechnology differently.
Experts and laypeople differ in their perception of risks associated with nanotechnology hazards. The public perceives higher levels of risk than experts, and experts have more trust in governmental agencies to protect people’s health from nanotechnology risks than the public does.

Kahan, Slovic, Braman, Gastl & Cohen, 2007
This study involves a panel of on-line survey respondents assembled by Knowledge Networks (N=1850) in late 2006. A full 81% of our subjects reported having heard either “nothing at all” (53%) or “just a little” (28%) about nanotechnology prior to being surveyed. Only 5% reported having heard “a lot.” Nevertheless, we also found that after being supplied with a minimal and nonjudgmental description of what nanotechnology is, the vast majority of
Americans are willing to offer an opinion about its relative risks and benefits.
Eighty-nine percent had a position one way or the other. Interestingly, although divided, Americans, on the whole, seem relatively pro-nanotechnology.
A majority, 53%, indicated that they believed nanotechnology’s benefits would either “slightly” or “strongly” outweigh its risks. Thirty-six percent indicated that they believed that nanotechnology’s risks would either “slightly” or “strongly” outweigh its benefits. There is clearly a white male effect in assessment of nanotechnology risks. Men and whites were significantly more disposed to see benefits as outweighing risks than were women and African-Americans, respectively. White males were the most disposed to see benefits as outweighing risks. The most striking differences were based on subjects’ levels of (reported) knowledge. “Low knowledge” subjects—those who indicated they had heard either “nothing at all” or “just a little”—were considerably more disposed to see risks as outweighing benefits than were either “moderate knowledge” or “high knowledge” subjects, whose respective positive views of nanotechnology benefits did not differ significantly. Interestingly, they discovered information doesn’t mater. The respective mean evaluations of nanotechnology risks of the information treatment group and the no-information group were statistically insignificant. The overall percentages of subjects in the information group who took the position either that benefits would outweigh risks or that risks would outweigh benefits were quite comparable to those in the no-information condition. By far the largest influence on affect was prior knowledge. The more subjects reported having heard about nanotechnology before being surveyed, the more positive their affective appraisal of it. Accordingly, if learning about nanotechnology does dispose persons to a more positive view, one might well have expected a sample so dominated by persons without substantial prior knowledge to shift toward a more positive view upon exposure to information. One might suppose that as members of the public learn more about nanotechnology their assessments of its risk and benefits should converge.
Their results suggest that exactly the opposite is likely to happen. Individuals who hold values that predispose them to credit claims of environmental risk generally tend to become alarmed, whereas those who hold values that predispose them to dismiss claims of environmental risk generally tend to be become reassured, as they are exposed to balanced information about nanotechnology’s risks and benefits.

Hart, 2008
In late summer 2008, Peter D. Hart Research Associates, Inc., conducted a nationwide survey among 1,003 adults about awareness of and attitudes toward both nanotechnology and synthetic biology. Two focus groups were also conducted in Baltimore. The large majority of Americans have little or no awareness of nanotechnology: less than one in four (24%) adults have heard some or a lot about it, including just 7% who have heard a lot, while three in four adults have heard just a little or nothing about it. Nearly half (49%) of adults say that they have heard nothing at all about it. This represents a slight decline in awareness since last year
(27% said they had heard a lot or some in 2007) and the year before (30% said they had heard a lot or some in 2006). There is a positive association between awareness of nanotechnology and the belief that the benefits of nanotechnology will outweigh the risks.

When those who express at least a minimal awareness of nanotechnology are asked where they heard about it, television is the top-tier source. They also mention the Internet, magazines and journals, and news programs and newspapers. Interestingly, adults with the highest level of awareness are most likely to cite magazines and journals as their information sources, while less-informed individuals are most likely to say that they heard about nanotechnology via television.

Nearly half of adults are too unsure about nanotechnology to make an initial assessment on the tradeoffs between risks and benefits. Of those who are willing to make a judgment, by three to one they think that benefits will outweigh risks (20%) as opposed to thinking risks will outweigh benefits (7%). The plurality, however, believe that risks and benefits will be about equal (25%). When asked to weigh the risks and benefits of nanotechnology in the absence of any definition or information about it, 48% of adults simply do not express an opinion. One in four believes that the risks and benefits will be about equal, 20% think that the benefits will outweigh the risks, and just 6% believe that the risks will outweigh the benefits. A comparison of the public’s initial, unaided impression of nanotechnology over the past three years reveals a slight trend toward a more positive assessment. In 2006, 15% of adults said that the benefits will outweigh the risks, and that proportion increased to 18% last year. There has been no shift in the proportion of adults who believe risks will outweigh benefits.

There is a strong association between awareness of nanotechnology and respondents’ initial impression that the benefits will outweigh the risks. Those who have heard more about nanotechnology are more likely to think that the benefits will outweigh the risks. Nearly half (49%) of those who have heard a lot about nanotechnology believe that the benefits will outweigh the risks, and the proportion who have this opinion decreases to 41% among those who have heard some about nanotechnology, 24% among those who have heard just a little, and just 8% among those who have not heard anything at all about it. (Men, college graduates, and higher-income individuals report the highest levels of awareness of nanotechnology, and they are the groups most likely to think that benefits will outweigh risks.) A lack of awareness does not translate into greater skepticism of nanotechnology though. Rather, two-thirds (65%) of adults who have not heard anything about the technology do not make a judgment on the risk benefit tradeoff.

Smiley Smith, Hosgood, Michelson & Stowe, 2008
A national random digit dialing telephone survey (N = 1014) was conducted by Peter D. Hart Research Associates, Inc., in the United States to assess knowledge of nanotechnology and perception of risk in August 2006. In the study population, 44.3% of men and 55.7% of women reported knowing just a little or nothing at all about nanotechnology. Men were 2.3 (95% CI: 1.72, 3.01) times
more likely than women to have heard a lot or some about nanotechnology. Age was also an interesting component, with younger respondents being significantly more likely to have heard a lot or some about nanotechnology.

This study is the first to our knowledge to develop a significant model of nanotechnology risk perception change. In particular, those who shifted to a perception that benefits outweighed risks were likely to be male, more highly educated, and Republican. Alternatively, those who shifted to a perception that risks outweighed benefits were likely to be female, less highly educated, and affiliated with the Democratic Party

Kahan, Slovic, Braman, Gastil, Cohen & Kysar, 2008
The study involved a sample of approximately 1,600 American adults and was conducted over a period of several weeks between June and August 2007. The subjects were drawn from a nationally representative panel recruited by Knowledge Networks and participated in experiments using Knowledge Network’s on-line testing facilities. The study occurred in two stages. The first stage (N-800) evaluated how exposure to balanced arguments unattributed to identifiable advocates would influence subjects’ perceptions of nanotechnology risks and benefits. The second (N=800) evaluated how exposure to the same arguments would influence participants’ perceptions when the arguments were attributed to advocates recognized as holding one or another set of cultural values. The information presented to the samples involved a no-argument and argument categories. No-argument condition involved a brief description of nanotechnology. The argument condition involved two subsets with one advocating suspension of development pending further health and safety research and another defending continued development also with further research. The second stage sample had argument randomly assigned to advocates from different cultural worldviews. The results revealed that cultural polarization interacts strongly with the relationship between subjects’ cultural worldviews and the perceived worldviews of those advocating one position or another on nanotechnology. While interesting, the findings are not relevant to this analysis.

As in the previous study, we found that the vast majority of the subjects (92%) had heard “little” or “nothing” about nanotechnology before the study. Overall, subjects exposed to argumentative information did not form risk perceptions significantly different from those of individuals not exposed to such arguments. However, as in the previous study, we found that various groups exposed to information became polarized relative to groups not exposed to information. They observed polarization along race, a fear of environmental risks in general, and prior knowledge about nanotechnology. “High-knowledge” subjects (those who claimed they knew either a “moderate amount” or “a lot” about nanotechnology before the study) had less concern about risk than did “low-knowledge” subjects (those who claimed than that they knew “nothing” or “only a little”) in both conditions. But the size of the differential was significantly larger in the argument condition.

Hamlett & Cobb, 2008
Citizen Technology Forums (CTF) in six cities in the United States throughout March 2008 (N=74). Citizens became informed about human enhancement technologies and they generated written reports about their concerns and recommendations regarding the development trajectory of these technologies.

All six sites, for example, expressed significant concern about (1) how to effectively regulate these new technologies and (2) they strongly endorsed programs intended to keep the public informed about human enhancement technology developments, including more deliberative panels and enhanced high school and K-12 education. On the issue of regulation, some sites advocated creating a new regulatory agency charged with managing these technologies, while others supported strengthening the Federal Drug Administration.

Pre-deliberation, for example, 82% of panelists were at least somewhat certain the benefits of enhancing human capabilities would exceed the risks; post-deliberation, however, the percentage was reduced to 66%. Likewise, deliberations increased emotional worry about affording enhancements. Before deliberation 63% were at least somewhat worried that the average family would not be able to afford enhancements; after deliberation, that percentage increased to 76%. Similarly, before deliberating, 48% of participants were at least somewhat worried that their own family would not be able to afford enhancements; after deliberating, that percentage jumped to 60%.

Kahan, Braman, Slovic, Gastil & Cohen, 2008
This is the second of Kahan’s cultural worldviews studies and confirmed earlier findings. The sample consisted of 1,850 subjects demographically weighted to reflect national representativeness and the data was collected in late 2006. . The subjects were administered an on-line survey-experiment that consisted of approximately 50 questions.

Within the no-information treatment, we found a correlation between familiarity with nanotechnology and perceptions of its risks and benefits. The vast majority of these subjects—over 80%—had heard either “a little” or “nothing at all” about nanotechnology before the study. Among the relatively small group of subjects familiar with nanotechnology—the ones who said they had previously heard either “some” or “a lot” about it—81% said they believed that the risks would outweigh the benefits, and only 17% that the benefits would out-weigh the risks. Among the much larger group who were relatively unfamiliar—those who said they had heard either “little” or “nothing” about nanotechnology—47% said that the benefits would outweigh the risks, and 40% that the risks would outweigh the benefits (Table 1).

Our results show that exposure to even a small amount of balanced in-formation about nanotechnology can result in polarization of this sort. Because individuals in the real world are much more likely to select information in a biased fashion that matches their cultural and political dispositions, one might anticipate even more extreme polarization outside the lab. Nanotechnology, on this view, could go the route of nuclear power and other controversial technologies, becoming a focal point of culturally infused political conflict.

Pigeon, Harthorn, Bryabt & Rogers-Hayden, 2008
This research involved four parallel workshops during 2007 in the USA and UK involving 12-15 people in each. One of the workshops in each country focused on energy and the other on human health and enhancement. It was supplement by a series of science cafes. They concluded benefit rather than risk continued to frame nanotech risk perception, applications means more than theory, and finally nanotechnologies so far do not appear to elicit beliefs about physical risk as such; rather, they stimulate discussion of social conditions.

Consistent with academic analysis of public discourses about new technology, and other qualitative studies of nanotechnologies in both countries, the issue of trust, and the potential activities of institutions such as government, regulatory agencies and corporations were discussed as a source of risk.

Scheufele, Corley, Shih, Dalrymple & Ho, 2009
The U.S. survey data was collected between 15 February and ended on 27 June
2007, using a dual frame method of national random digit dial and listed household phone survey. N = 1,015, with a response rate of 30%. The Eurobarometer public opinion surveys use a multistage national probability sampling technique, the Eurobarometer 64.3 provided opinion data collected from 29 countries through face-to-face interviews of 29,193 Europeans aged 15 and above. The fieldwork was conducted between 5 November and 7 December 2005.

Religious beliefs may be part of the value systems people use when they make sense of science and technology more broadly. Based on country-level data, we see a negative relationship between levels of religiosity and beliefs that nanotechnology is morally acceptable. The proportion of respondents who disagreed that nanotechnology was morally acceptable was highest in the United
States (24.9%) and lowest in Italy (7.3%). The percentages for respondents who agreed was highest in Belgium (82.4%) and lowest in Ireland (33.5%). The majority of respondents who saw nanotechnology as morally acceptable also supported nanotechnology under existing or tighter regulations. The authors claimed a robust relationship between levels of religiosity and public support for nanotechnology across all countries.

Corley & Scheufele, 2009
This study re-examines the 2004 and 2007 knowledge gap. The survey involved using a dual frame method of national random digit dial and listed household phone survey. N was 1,015 with a 30% response rate. They found while respondents with at least a college degree have experienced an overall increase in nanotechnology knowledge between 2004 and 2007, respondents with less than a high school degree have experienced a decrease in nanotechnology knowledge levels over the same time period. We also show that exposure to the internet significantly improves the knowledge level for those with the lowest levels of education while there is a lower positive impact of internet exposure on those with higher levels of formal education.

Our analyses showed that those respondents with at least a college degree displayed an increase in knowledge levels between 2004 and 2007 while respondents with education levels of less than a high school diploma had a significant decrease in nanotechnology knowledge levels between 2004 and 2007. These clear discrepancies in levels of factual knowledge about nanotechnology among U.S. respondents with the highest and lowest levels of formal education have both positive and negative implications. On the one hand, the significant learning that occurred for highly educated respondent in our data will hopefully attenuate concerns about static levels of awareness and knowledge about nanotechnology, at least for this subset of the population. On the other hand, however, our data suggest that efforts to increase public understanding about nanotechnology have not helped the group that might need it the most: those with the lowest levels of formal education. Among this group, nanotechnology knowledge levels have in fact decreased over time, suggesting that we have not done a good job of educating this segment of the public about an issue that may be increasingly difficult to understand for lay audiences, given fuzzy regulatory scenarios, inconclusive reports about risks, and limited coverage in mainstream media.

Our data results showed that internet exposure was significantly related to knowledge levels about nanotechnology over time, especially for those with low formal education levels. Exposure to television and newspapers was not significantly related to knowledge level. Respondents with higher levels of formal education displayed similar trends in knowledge levels between 2004 and 2007 regardless of whether they had low or high levels of internet exposure. At the moment, we are not just seeing existing gaps between citizens based on their educational attainment, but our data also illustrate widening gaps between the already information-rich and the information-poor. Closing these gaps is not an option; it is a necessity.

NANOPARTICLES IN H1N1 SWINE FLU VIRUS VACCINE????

The article that has been associated with the claim on nanoparticles in the H1N1 Swine Flu vaccine can be tracked to F. William Engdahl at Global Research. He claimed on September 14: “Vaccines which have been approved by government authorities for vaccination against the alleged H1N1 Influenza A Swine Flu have been found to contain nano particles. Vaccine makers have been experimenting with nanoparticles as a way to “turbo charge” vaccines for several years. Now it has come out that the vaccines approved for use in Germany and other European countries contain nanoparticles in a form that reportedly attacks healthy cells and can be deadly.”

FIRST, Engdahl's claim alleges this vaccine may have been approved for use in Europe. Its role, if any, in America is very unclear.

SECOND, the vast bulk of the reportage claiming that nanoparticles are in the new vaccine is directly traceable to this single individual. Engdahl is a well-known fear monger and author of Full Spectrum Dominance: Totalitarian Democracy in the New World Order. If you want to learn more about him visit his website.

THIRD, his evidence is drawn from the EPFL publication that describes research rather than production. Bioengineering researchers from the EPFL in Lausanne, Switzerland, have developed and patented a nanoparticle that can deliver vaccines more effectively, presumably with fewer side effects, and at a fraction of the cost of current vaccine technologies. This research is reported in a recent issue of Nature Biotechnology.

It is important to note that many research teams are engaged in research of this type. For example, researchers at Oregon State believe lecithin nanoparticles have wide potential applications and possibly a good safety profile. Their findings were just published in the Journal of Controlled Release in work supported by the National Institute of Allergy and Infectious Diseases. In addition, some companies have made claims associated with hypothetical applications of nanoparticles. According to a presentation by BioSante Pharma at the recent Immunotherapeutics & Vaccine Summit, the presenter claimed BioSante’s vaccine adjuvant, BioVant™, increased the protective effect of vaccines for multiple flu strains, including a potential new vaccine against H1N1 (swine flu). Allegedly, BioVant involves calcium nanoparticles.

As to the vaccine, even FOX News reported: "They’re pushing it as fast as they can, but they still have to meet good manufacturing standards," said Dr. Peter Gross, senior vice president and chief medical officer at Hackensack University Medical Center. "It will be tested to make sure it’s safe and contains the proper amounts of protective antibodies," said Gross, who tested flu vaccines for 20 years for the U.S. Food and Drug Administration.

S.NET IN SEATTLE (SLEEPLESS?)

2009-09-14T11:27:00.011-05:00

CENTER FOR WORKPLACE DEVELOPMENT

Last weekend (September 8-11) the folks at the Center for Workplace Development at the University of Washington held a one-day graduate student nano-ethics program. I spoke on uncertainty and how it is used strategically by NGOs and toxicologists to secure memberships, funds, and prestige at the expense of regulation. I believe all the presentations on that day were recorded and will be posted somewhere. I have copies of my powerpoint at our NIRT site at NCSU. You can download it.

THEN CAME S.NET

S.net is a new organization or not. Its mission while well written seems to open opportunities for international cooperation especially between Europe and the United State (who dominate the organization) to engage in scholarship on the philosophy and ethics of emerging technologies (read as nanotechnology at this time). Whether we need another organization seems unclear to me. Personally, I belong to AAAS, 4S, ACS, MRS.... and am loathe to join another. Of course as you are aware I am not a philosophy professor though I am an amateur ethicist. Though I probably won't participate actively in this group, they have every right to exist but I am not sure what they are going to offer the debate over nanotechnology.

So S.net [Society for the Study of Nanoscience and Emerging Technologies](which doesn't seem to have a dedicated web presence yet) got a $50,000 grant from the NSF to piggyback their first conference at the same site at the U Washington CWD project. There were three days of papers and some plenary presentations. I attended some. The papers were mixed as they always tend to be though the event showcases two schools more than any others: UCSB and ASU (both current CNS (Centers for Nanotechnology in Society) sites with both directors on the operating board of S.net. Hopefully, S.net will be more than a showcase for these two schools since they already have extensive press machines funded in part by the NSF. We will see. There is a call for papers for the second conference to be held in Germany (see Nanotech Now.

Presentations by Mowery, Vogt, Kysar, and Baird were accessible and informative. Mine was adequate as well. You should check out the CWD site at U Washington for more.

I am at the NISE.net meeting for three days before getting back to Raleigh on Friday.

IS NANOTECHNOLOGY NEWSWORTHY?

2009-08-24T13:03:00.003-05:00

Is nanoscience newsworthy? Why would the media fail to cover a study (Song et al previous post) whose findings allege deaths from exposure to nanoparticles? Is this about the media per se, the subject matter per se, or those responsible for posting information about nanoscience and nanotechnology. The National Nanotechnology Amendments Act of 2009 is working its way out of the Senate commerce Committee. The Snowe/Kerry version may go head to head with Hutchinson's. In the end we will need appropriations as well as authorizations and that may necessitate some public support. That prospect may be a pipedream.

Recently some of the NanoNews feeds stopped. Julia moved on. UCSB stopped sending its news updates. Meridian stopped as well. We decided that while NanoWerk, Nanovip, NanotechNews, Topix Nanotechnology News, AtoZ Nanotechnology, Nanotechnology.com, NanoTechWire.com, and the Nano Science and Technology Institute are compiling information, the public was once again on the short end of the stick. While there are professional journals, when the public learns about nanoscience and nanotechnology it is after a lot of work searching for the information or the result of some negative reporting.

We are going to continue to report summaries of important news reports on this blog interspersed with other commentaries. Check here regularly and you can read Nano News Summaries: Breakthrough Newsworthy and Honorable Mentions. Two graduate students from NCSU and PCOST (with funding from the NSF) will be compiling this material and Berube will edit.

Berube is preparing a report and will be presenting at the 4S meeting this semester that tries to explain why the public with knowledge about nanotechnology hasn’t increased appreciably from 2004 to 2007, I began positing rationales: inadequate research designs, reporting tails (2004 and 2007 as tails to a normal frequency distribution), and thresholding (we’ve reached the population with interest), this phenomenon is intriguing. he would have liked to complete a metanalysis but getting my hands on all the research data has become problematic for many reasons, so he will do a metanalysis and will report here.

Is it important for the public to attend to information on nanoscience?
Is anyone really making an effort to get the public involved? Or is all this talk about public engagement simply “smoke and mirrors”?
Is the public wholly indifferent to what is happening in nanoscience?

So we tracked what has been going on with media coverage of the Song article on Chinese women exposed to nanoparticles. The purpose was to gathering evidence to demonstrate amplification of the news versus the replication of news on the internet. We tracked message dissemination via Google search at intervals of 24, 48 and 96 hours after the original Song article was published. What was found was that a great many hits found by Google for the search [“Chinese women” nanoparticles] yielded repetitive results. The majority of hits found by Google were replications of a singular article originally published by Rueters’ Tan Ee Lyn, causing the author to be omitted from future searches for comparison [omit: “Tan Ee Lyn”]. Hardly any other mentions were found (although Nano-hype was in the top 10 hits). The actually frequencies are as follows:

First 24 hours (0-24) after the original publishing – 177 results (only 23 results not attributable directly or indirectly to Tan Ee Lyn and Reuters)
Second 24 hours (25-48) after the original publishing – 612 (narrowed down to 30 non-Reuters results)
Following 48 hours (48-96) after the original publishing – 8 results

SIMPLY PUT the media doesn't seem to want to cover nanoscience issues, even when we are talking about exposure to nanoparticles that may have resulted in two deaths and a handful of hospitalizations. I will leave deeper analysis for later but there are many reasons:
not American or Western women.
not men.
not newsworthy.....

TIME TO RE-EXAMINE how the nano-community is reaching out to the public. The perception studies are problematic and seem to suggest we have thresholded out. The recent experience with the Song et al study on Chinese women validates media disinterest even when the subject is controversial. MAYBE NANO has moved into its adolescent phase where we are no longer impressed by the latest sports equipment and promises of great things to come. MAYBE the hyperbole has run its course. Thanks to Meghnna Tallapragada for tracking this event.

NANOPARTICLES RESPONSIBLE FOR DEATHS OF TWO CHINESE WOMEN???

2009-08-18T12:40:00.007-05:00

The provocative title was selected as a teaser for a study reported on August 19, 2009 in a European journal. The article can be found the European Respiratory Journal. Vol. 34, pp. 559-567. The study is clinical and examine 7 female Chinese workers diagnoses with lung damage. Two of the women died. They worked in a facility spraying a polyacrylic paste onto a polystyrene substrate. The work area had rudimentary exhaust ventilation which had broken down and (presumably) had gone unrepaired. ~30 nm diameter particles were found in fluid surrounding the lungs of the patients. Similar sized nanoparticles in the polyacrylic paste and the ventilation system were discovered. The authors claim the damage and deaths were attributed to nanoparticles. I will leave the technical examination of the study to others.

First of all this is an important set of findings. Despite weaknesses in design the results are potentially explosive especially if they are amplified by some public advocacy groups and the media.

As a former journalist I would advise a journalist covering this set of findings to ask the following four questions.

2 women are dead allegedly from inhaling nanoparticles. What assurances are there that a situation like this cannot happen here?
As globalization accelerates and supply lines cross continents, what assurances can be given that finished products will be sold involving assembly and fabrication such as that which occurred in China?
Even if efforts are taken to protect worker safety, here and abroad, how effective are hoods and masks in effectively reducing exposure to nanoparticles? How do we know they will be effective?
Given the uncertainties associated with nanoparticles and their control and toxicity, why should we proceed with nanoparticle production when there are reasonably available substitutes? Wouldn’t it be more prudent to consider moratoria or a much slower pace of development?

As an argumentation specialist, there are two major issues (loci) here. The only way to frame the issue out of the hands of ultra-precautionists is to address both of them.

The case for worker safety in the NanoWorkplace and
The case for enforcement of regulations involves global trade involving nanoparticles.

SEPARATING THE HYPE AND THE BUZZ 070109

More.

We have one breakthrough and twelve (12) noteworthy articles and report and a pile of honorable mentions. This is the last post for a week until I can catch up on a stack of reports.

BREAKTHROUGH

U of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs.
See EurekaAlert, June 19, 2009 and Chemical Science, June 5, 2009.

NEWSWORTHY

1. EARLY DETECTION OF BLINDNESS.
Researchers from the U Kentucky claim to be able to detect abnormal blood vessels in the living eyes of mice by attaching anti-CCR3 antibodies to tiny semiconductor nanocrystals called "quantum dots" and injecting these into the mice. Early detection may improve treatment regimens.
See Nanowerk, June 15, 2009 and Nature, June 14, 2009.

2. DRUG DELIVERY
Cornell and Shenzhen U researchers claim to have developed a technique that could one day be used to deliver vaccines, drugs or genetic material to treat cancer and blood and immunological disorders. The research involved nanocapsules containing a small-interfering RNA.
See Cornell Chronicle, June 25, 2009 and Gene Therapy Online, June 25, 2009.

3. REACH HAVING CLASSIFICATION ISSUES
Confusion over classification of nanomaterials under the Reach chemicals legislation has led to two groups of companies using different criteria to submit data on carbon nanotubes to the European Chemicals Agency (ECHA). Currently there is so much uncertainty about dealing with nanomaterials under the Reach regulations (which came into force in 2008) that different groups of companies are forming separate data-gathering bodies, called substance information exchange forums (SIEFs), to deal with carbon nanotubes (CNTs).
See Chemistry World, June 16, 2009.

4. EPA ISSUES NANO RULE
U.S. EPA issued a final rule for carbon nanotubes under the Toxic Substances and Control Act, subjecting them to a "new-use" regulation that gives the agency greater authority. Makers of certain carbon nanotubes, as well as those of 21 other chemicals, now must notify EPA at least 90 days before starting manufacturing. The rule takes effect Aug. 24.
See EENewsNet, June 24, 2009.

5. NANO TERM ADDED VALUE OR NOT
A researcher at the National Institute for Consumer Research in Norway claims companies may be less inclined to highlight nanomaterials in their products. While his sample is small, he searched a website run by a major international cosmetics company, using keywords like 'nanotechnology' and 'nano', to estimate how many products contain nanotechnology. His search turned up 29 products in 2007, but when he repeated the same exercise recently, there were zero hits. This, he said, suggests that companies may now view 'nano' as a negative label rather than an added value. Another interpretation could be these products were never marketed or their composition changed to reflect any negative association OR companies have decided to simply move on, add nano-ingredients, and fail to inform consumers. Interesting theses.

12. NANOPARTICLE UPTAKE IN MARINE ECOSYSTEMS.
Researchers at the U of South Carolina observed that clams and biofilms accumulating the most nanoparticles by mass. This could be a serious problem if the same thing happened in the natural environment because biofilms are used as food sources for several different kinds of detritivores, some of which are prey for larger arthropods and small fish.

SEPARATING THE HYPE AND THE BUZZ 041509

2009-06-29T14:15:00.008-05:00

This took some time. A lot happened in April. There were three notable breakthroughs, nine (9) noteworthy news stories, and quite a few honorable mentions. My students convinced me to work harder on my hyperlinks. We read every article that comes across our desks and aggressively search out everything we can find.

Tell your friends and let me know which format you prefer.

BREAKTHROUGH – NANOSCALE RINGS

Researchers at Cal Tech and Berkeley report a direct catalytic route for making nanoscale rings with potential applications in drug delivery and organic photovoltaic devices.

See C&EN, April 20, 2009 and J Am Chem Soc,

BREAKTHROUGH – NANOPARTICLE THIN FILMS

Researchers at MIT have used capillary condensation to functionalize inorganic nanoparticle coatings that could be used to make transparent thin films for applications like imaging devices and memory storage. The technique also bypasses the need for toxic, co-solvents during processing.

See NanotechWeb, April 24, 2009.

BREAKTHROUGHS – DNA SEQUENCING

Researchers at Oxford and Oxford Nanopore Technologies demonstrated that the four standard DNA nucleotides—adenine, thymine, guanine, and cytosine can be distinguished from one another reliably by the amount of current they each block as they flow through a nanopore. Taking DNA apart one nucleotide at a time, directing the nucleotides sequentially into a nanopore, and detecting them with an electrical current meter may seem an unlikely DNA-sequencing concept, but it is closer than ever to being a reality.

See C&EN, March 9, 2009 and Nature Nanotechnology, DOI: 10.1038/nnano.2009.12.

NEWSWORTHY

1. AUSTRALIAN TRADE UNION DEMAND NANO-REGISTRY

The Australian Council of Trade Unions (ACTU) is calling for a mandatory national register of who is importing, manufacturing, supplying and selling nanomaterials.

See Sydney Morning News, April 13, 2009.

See Nanowerk, April 24, 2009.

3. FLEXIBLE BATTERIES USING VIRUSES

Researchers at MIT use viruses to build both the positively and negatively charged ends of a battery, the cathode and anode. The virus was coaxed into binding with iron phosphate and then carbon nanotubes to create a highly conductive material. While the prototype battery is currently the size of a coin, the scientists believe it can be scaled and be used to create flexible batteries that can take the shape of their container, which is perfect for mobile or small devices.

See BBC News, April 2, 2009.

4A. SOLAR CELLS USING DIATOMS

Researchers at OSU and Portland State U have created a new way to make "dye-sensitized" solar cells using diatoms, in which photons bounce around like they were in a pinball machine, striking these dyes and producing electricity. This technology may be slightly more expensive than some existing approaches to make dye-sensitized solar cells, but can potentially triple the electrical output.

See Science Daily, April 9, 2009.

4B. SOLAR ADVANCES USING RESIDUE

Researcher from Northeastern U and NIST discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes-a residue that wasn't even noticed before this-plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas from water. By controlling the deposition of potassium on the surface of the nanotubes, engineers can achieve significant energy savings in a promising new alternate energy system.

See AtoZ Nano, April 24, 2009.

SEPARATING THE HYPE AND THE BUZZ 033109

2009-06-29T14:04:00.013-05:00

SORRY for the delay but I have been all over the place. Went to DC for a SRA meeting on Regulatory Impact Analysis and to Chicago for a meeting of the International Food Information Council Foundation Trustees meeting. I spoke (officially) in Chicago.

The nano-frontier is still pretty wild and I hope to run out some data we recently compiled on experts and their understanding of nanoparticles very soon. Some of the findings were leaked at the IFIC meeting and you can find that at our web site (pcost.org).

As for March 2009, we have nine (9) notable and a smattering of honorable mentions.

1. TOXICITY TESTING QUANDARY
U. Minnesota and U. British Columbia researchers reported if all existing nanomaterials were to be tested for toxicity, it would cost U.S. industries between $249 million and $1.18 billion, but the testing could take as long as 53 years at current levels of investment. Does this mean we need a bigger investment in toxicity testing or find new ways to test nanomaterials or both? (See ES&T DOI 10.1021/es802388s)

2. NEW WAY TO TEST FOR INHALATION
Scientists at the University of Bern and the Swiss Federal Institute of Technology (ETH) in Zurich designed a sealed glove box system where nanoparticles are simultaneously made in aerosol form and then deposited onto lung tissue cells.

3. GREEN NANOMATERIALS
Researchers are creating green nanomaterials, with an eye toward their hazards as well as cleanup potentials and pitfalls. (See ES&T, 43:5, 2009, 1247-1249)

4A. CANCER GENE THERAPY
Cancer Research UK scientists have for the first time developed a treatment that transports 'tumor busting' genes selectively to cancer cells (mice study).

4B. MORE CANCER GENE THERAPY
U London School of Pharmacy reports a way to switch off cancer-causing genes and trigger cell death. It is based on nanotubes used to deliver small interfering RNA (siRNA) directly into the tumor mass, which it is hoped will have a significant impact in the battle against lung cancer.

5. PESTICIDE APPLICATIONS
Cornell U researchers how found a way to apply pesticides by encapsulating them in biodegradable nanofibers, which keeps then intact until needed and minimizes loss to drift or being washed away from the plants they are intended to protect.

6. GATES FOUNDATION AND NSF
The Gates Foundation money will be used to bring in researchers from around the world, particularly developing countries. The new program is called BREAD, Basic Research to Enable Agricultural Development. NSF Program Director Deborah Delmer said it will cast a wide net for new ideas and approaches to common problems like poor soil quality, crops that spoil during storage and plant strains that wilt in today's heat — and may fare even worse as climate change raises the planet's temperature.

7. FDA – TEXAS CONSORTIUM ANNOUNCED
The U.S. Food and Drug Administration (FDA) announced the creation of a nanotechnology initiative in collaboration with the eight Texas academic institutions that make up the Houston-based Alliance for NanoHealth. (These include Rice U, the U of Texas, and the M.D. Anderson Cancer Center.)

8. EU COSMETICS REGULATIONS ON THE HORIZON
Parliament approved an update of EU legislation on cosmetics when it votes on a first-reading agreement thrashed out between EP and Council representatives. The basic aim of the new regulation is to remove legal uncertainties and inconsistencies, while increasing the safety of cosmetics. Parliament's amendments add further improvements, especially regarding the claims companies make for their products and the safety of nanomaterials used in cosmetics.

9. SUNSCREENS ALLEGATIONS
U Toledo researchers found nano-titanium dioxide used in personal care products reduced biological roles of bacteria after less than an hour of exposure. Utah State U and U Utah researchers found beneficial soil bacteria cannot tolerate silver, copper oxide and zinc oxide nanoparticles. Both presented at ACS meeting in Salt Lake City.

HONORABLE MENTION

PAPER FOR ELECTRONIC DEVICES
Kyoto University researchers made transparent paper from nanosized cellulose fibers (renewable) as alternative to glass and polymers in electronic devices. Findings were presented at the Salt Lake ACS meeting.

EU NANOFOOD CONCERNS
In a legislative report dealing with an update of the EU rules on novel foods, the European Parliament calls on the Commission to interdict the placing on the market of food derived from cloned animals and their descendants. MEPs also want food being produced by nanotechnology processes to undergo a specific risk assessment before being approved for use and be labeled.

SAUDIS NEW NANO COMPANY
Saudis open the Saudi Nanotechnology Company. According to chairman Prince Bader Bin Saud said the firm would provide the Kingdom with a means of keeping pace with worldwide developments in nanotechnology, rather than it having to rely on foreign research.

HYPE ALERT
Check the Mental Floss website, for How to Destroy Civilization with Nanotechnology" directed by Ransom Riggs. WIRED Science reports: Several teams of social scientists are hard at work, trying to answer that question, and movies like this could turn their world upside down. Nice rhetoric but hardly.

TUNNELING NANOTUBES
Glowing infectious proteins called prions move through a network of mouse brain cells linked by tunneling nanotubes. Experiments are revealing that the tiny threads ferry both beneficial and harmful cargo between cells.

CHINA’S NANO-SPEAKERS
Tsinghua U. used a slim film of see-through plastic to transform almost any surface into an auditorium. It is made from nanocarbon tubes which, when heated, make the air around them vibrate, producing the sound.

NANOLUB
NanoLub has produced a nanotechnology-based (tungsten disulfide)lubricant which can enhance compression efficiency and a reduction of over 5% in fuel consumption of the vehicles.

BERUBE IS BACK

SEPARATING THE HYPE AND THE BUZZ 020509

2009-02-05T12:39:00.005-05:00

Week on February 1, 2009.

Been on the road at ILSI-NA inTucson and a ski trip to Utah.

There were six major events and some minors ones.

1. THE “A” WORD (ASBESTOS)

The 2020 Science Blog hosted by Andrew Maynard addresses the high aspect ration of nanoparticles (HARN) reviewing the recently released DEFRA Report. Andrew adds we are funding the wrong research and this failure and specifically to HARN issue “could cost some sectors of the nanotechnology industry dearly if clear information and safe working guidelines aren’t forthcoming soon.” This post is a fairly good review of what has been said and reported to date. Go to http://2020science.org/2009/01/23/asbestos-like-nanomaterials-should-we-be-concerned/. The Report on Project CB0406 was dated August 13, 2008 (http://www.safenano.org/Uploads/HARN.pdf). Andrew does a good job of examining HARN and the fiber paradigm.

2. REGULATION ON TWO FRONTS

Switzerland’s Centre for Technology Assessment (TA-Swiss) has called for the existing legislation on foods and chemicals to be adapted to meet the demands of nanotechnology. See http://www.foodproductiondaily.com/content/view/print/233888. This is another food and nano report. You can read the abstract at http://www.ta-swiss.ch/e/them_nano_nafo.html. AND we are anticipating the release of regulations on industrial use of engineered nanoparticles in Canada (http://www.nanowerk.com/news/newsid=9060.php).

3. SELF DISINFECTING FILM

Developed by ETH Zurich and being produced by Perlen Converting AG Company this film has anticipated uses at hotspots for germ transmission in hospital facilities. See http://www.nanowerk.com/news/newsid=8997.php.

4. DEMRON PATENT

This is presumably the world’s first and only protective material for all types of chemical, biological, radiological and nuclear incidents. Demron is an advanced radiopaque nanopolymeric compound fused between layers of fabric and manufactured into lightweight nuclear radiation blocking garments including full-body suits, vests, blankets and medical X-ray vests and aprons. Pretty cool. http://www.nanowerk.com/news/newsid=9042.php

SEPARATING THE HYPE AND THE BUZZ IN THE NEWS 011809

2009-01-20T18:48:00.002-05:00

Week of January 18, 2009

There were six major events and some minor ones. I hope you enjoy the new direction the blog is taking.

1. THE NNI AMENDMENTS

This week, the House Science and Technology Committee introduced H.R. 554, National Nanotechnology Initiative Amendments Act of 2009. It is much too early to see what effect this resolution will have since there are many more hoops. The community is watching whether there will be an increase in funding for EHS research and some others are waiting to see if a societal guru is part of the package. Selecting someone for that short list will be nearly impossible though watching some of my colleagues jockeying for position could be highly entertaining.

2. EPA’S VOLUNTARY SCHEME SHORTCOMINGS

Another set of big stories related to the poor track record for the EPA’s voluntary reporting scheme. The interim report does not bode well for the voluntary systems staving off harder regulatory options. Richard Denison goes a step further claiming the EPA “squandered precious time” with the voluntary scheme. See his blog entry for more - http://blogs.edf.org/nanotechnology/2009/01/12/62/.
While I wouldn’t go as far as Richard, there seems to be a mixed bag of success and shortcomings associated with the scheme though the successes are harder to discern than the shortcomings.

3. SMEAR CAMPAIGN ON NANOPARTICLE SUNSCREENS

This article was anticipated. What happens when an NGO, like FOE Australia, spreads misinformation about the risks of nanoparticle infused sunscreens in a country with the highest sun exposure melanoma rates in the world? Well, people stop using it and the melanoma rates increase claiming health and lives along the way. There is little evidence this has happened but apprehension was voiced by New South Wales Cancer Council this could be happening. You will definitely hear more about this since I have folks trying to determine how to generate data on this effect. If you want to read the article, it is archived at the Sydney Morning Herald and ran on January 11. (http://www.smh.com.au/news/national/smear-campaign-against-suncream-is-risking-lives/2009/01/10/1231004355070.html).

4. SILVER NANOPARTICLES AND DEFORMITIES

I am going to try to learn more about this reported conclusion for the National University of Singapore team led by chemist Suresh Valiyaveetil. This involved some human cell and zebra fish research and was reported at a Cochin conference in Kerala, India. This was reported on January 9. For more information, check ExpressBuzz (http://www.expressbuzz.com/edition/default.aspx).

5. NANOENGINEERED CAPSULES TO PROTECT ACTIVE PEPTIDES FOR DELVIERY TO ANTIGEN PRESENTING CELLS

Here was a small story with a potentially large impact. This report comes from a Melbourne team headed by Frank Caruso. Caruso claims these capsules might be highly effective in stimulating immune responses. This could represent a significant development in vaccine research and we should keep tabs on this work. This was reported by Nanowerk on January 13 (http://www.nanowerk.com/spotlight/spotid=8863.php).

6. REMOVING LEAD FROM BLOOD

A Korean team led by Won Seok Han and Jong Hwa Jung reported this finding. Magnetic nanoparticles can presumably eliminate up to 96% from the bloodstream and this does not involve the chelation method and would work more like dialysis. The results were reported in Angewandte Chemie. This was reported in AtoZ Nano on January 15. (http://www.azonano.com/news.asp?newsID=9430).

2009 STATE OF NANO

2009-01-15T14:47:00.019-05:00

I know I have been hardly focused on my blog these days. The new job at NCSU and the new grant has been keeping me very busy. I apologize. However, I have been given full release from all teaching duties at NCSU by a great dean and department chairman. I am writing some books, speaking at conferences, and working on my grant as well as writing some new proposals.

As you are aware, I have a small staff of graduate students and we have been working on a NIRT as well as some other projects. When I came to NCSU the goal was for me to create a project (soon to become a center) associated with the Public Communication of Science and Technology (PCOST). This is well on its way and I have met with architects who are designing our suite of offices in a building on NCSU's Centennial Campus. More on this later (http://communication.chass.ncsu.edu/pcost/index.html).

One of these projects are Citizen's Guides to Nanotechnology (CGN).

What are CGNs?

CGNs are written in a registry (term used in journalism to describe writing styles usually designed hierarchically against different types of audiences) appropriate for public consumption. CGNs do not cover the subject material exhaustively. Instead, they expose the reader to a sense of the subject material. In addition, they are electronic and will be edited. Hence, the first posted edition is 1.0 and we expect many subsequent posted editions.

Where are CGNs?

http://communication.chass.ncsu.edu/citizenguidetonano/publications.html

Why CGNs?

There are many reasons. First and foremost has been the dismal failure on the part of the social science and societal researchers to provide a true clearinghouse for the general public. At best, we get a spattering of offerings and extensive digital libraries of technical papers and reports. Second we have a tendency on the part of media to exaggerate findings and concerns to increase viewership and readership. This often leads to fear appeals of all sorts. (I have a major piece on fear and nanoscience forthcoming). Third, my graduate students needed to learn how to communicate to a broad collection of audiences beyond the traditional academic ones that dominate their publishing outlets. As a scholar in public sphere discussions, I was drawn to move them toward learning to speak in a public registry. Finally, we have generated one of the most complete libraries of nanoscience and nanotechnology materials we feel exists. It includes nearly every government report and nearly every publication in the popular literature on nanoscience and nanotechnology. This file is huge and occupies six shelves, four file drawers, and a multi-gig digital library as well. Every article we felt was important and many that were not that appeared on the WWW was printed as a pdf into our electronic library so nothing has been lost. In addition, one of my students is converting hard copy to digital copy and we are posting our library on a university website so all researchers involved in our program can access the material (more on this later).

The first issue is on Nano and Cosmetics and was driven by the work I did for my recent articles in the Journal of Nanoparticle Research in December 2008. [ “Rhetorical gamesmanship in the nano debates over sunscreens and nanoparticles,” Journal of Nanoparticle Research, 10. December 2008, 23-37. DOI 10.1007/s11051-008-9362-7 and “Reply from David Berube, NCSU,” Journal of Nanoparticle Research. 10. December 2008, 265-266. DOI 10.1007/s11051-008-9442-8.]

The second and third issue are being prepared. We have one on food products and another on food production. Others as you can see from our website (above) are in preparation.

So what is up with the blog?

I decided the best thing I can do is write about the state of nano on a weekly basis. Each week as we archive the week's articles in our virtual library, I will take notes and report what is happening and why what is reported as happening might be important. Unlike all other sites, we will not simply link you to article you can read on your own, we will digest the material and try to explain why it is or is not important, highlighting hyperbole and questioning focus.

Hope you enjoy the new direction for the blog. And expect weekly blogs (nothing like a promise to get me back to the keyboard).

INTERNATIONAL WORKSHOP HITS ITS MARKS

On August 28-29, 2008, the College of Humanities and Social Sciences (CHASS), the Department of Communication, and the Public Communication of Science and Technology Project (PCOST) hosted a workshop on “Communicating Health and Safety Risks on Emerging Technologies in the 21st Century” at the McKimmon Center on the North Carolina State University campus in Raleigh. The workshop was a deliverable associated with a $1.4M NSF grant on “Intuitive Nano-toxicology.”

David Berube, professor in Communication is the principle investigator for the grant and a national expert in the social science of nanoscience. He co-hosted the event with the PCOST Assistant Director Christopher L. Cummings, and four graduate students in the Communication MS program and the Communication Rhetoric and Digital Media doctoral program at NCSU: Katie Hayes, Jason Kalin, Kelly Martin, and Dan Sutko.

The workshop was webcasted and many participants presented from remote locations. The electronic and digital nature of the workshop was one of its features. Overall, the technical elements of the workshop were a great success with presentations delivered from off-base locations in Knoxville, Los Vegas, New Haven, Philadelphia, and Bethlehem, PA. Questions were asked via emails. A technical report on the conference can be read at http://nanohype.blogspot.com/.

The keynote speech was delivered by Lennart Sjöberg from the Center for Risk Research and the Stockholm School of Economics. The closing address was given by William Kinsella, professor in Communication and a member of the Science and Technology Studies (STS) program at NCSU. Both addresses and those of the other participants were highly praised.
Two presentations from Dan Kahan, professor of Law at Yale University and Dietram Scheufele, professor of journalism at the University of Wisconsin involved data never before shared to any audience. In addition, there were some outstanding toxicological reports given by professors Vicki Colvin from Rice University, Tara Sabo-Attwood from the University of South Carolina, and James Bonner from NCSU. A full set of the Power Points are up and they will be followed by streaming videos of the presentations at - http://communication.chass.ncsu.edu/nirt/Deliverables.html.

The next step in the grant deliverables involves a series of Delphi studies that will be co-designed by Professors Berube and Scheufele with input from the other members and the grant team. The survey will be administered by the co-principle team from the University of South Carolina under the direction of Professor Robert Oldendick at the Institute for Public Affairs and Policy.

TECHNICAL REVIEW OF THE WORKSHOP

2008-08-29T09:11:00.002-05:00

This workshop was hobbled by (1) the transfer in which the value of the grant demanded less funds to support a conference, hence we transitions to a workshop, (2) the proliferation of meetings and conferences has made it very difficult to get people together especially the world of nano and risk communication [it is a very small population], and (3) the economy led to many universities cutting back on support for travel funds.

This led me to take more seriously remarks made by Dawn Bonnell (U Penn) earlier this year at a meeting on nano-bio held in Ispra, Italy. It is time to use the technology at our hands to enable remote participation - webcasting and web-conferencing. Thanks to a strong tech team at NCSU we took a stab at this.

The results have been archived at our site and we webcasted the entire workshop on August 28-29, 2008.

We did learn a few things:

1. Rent a facility and pay the technicians.
2. Mike all speakers for archives.
3. Nail the live speakers to a spot on the floor so head insets are easier.
4. Record on studio quality tapes and have two tape decks esp. if you plan to archive the materials so they can be downloaded and streamed.
6. Connections need to be rehearsed with technical staffs at both locations. There are a variety of ways to do this including desktop systems such as Skype Meeting and iChat. However, the quality of free meeting software is mixed.
7. Power points needs to be designed to accommodate the video of the speaker (one quadrant needs to be designed without text or photo). Re-design templates so they are more appropriate for webcasted presentations with insets. Print and business of the slides can be problematic as well. Speakers need not to point at their PowerPoints with a laser pointer or a finger or even a fist because that doesn’t translate given how the broadcast has been planned.
8. Inset videos of the speakers needs to be fed from the remote site correctly. If the remove site fails to send the correct feeds
9. The primary issues are receptivity by the PC at the other end. Most webcast professionals can broadcast at high speeds but the Internet itself can be problematic. There are delays and glitches that impact receptivity.
10. In terms of streaming videotaped lectures there are many different software packages and we have not examined all of them though Final Cut with compressor seems to be effective.
11. It might be useful if we could tell the audience when they are on.

A summary and an updated version of this will appear in our annual report and maybe a publication.

DAY 1 of WORKSHOP completed - summaries posted below.

SUMMARY OF SPEAKERS AND THEIR PRESENTATIONS.

It is important to note that we will be streaming all the presentations and you will be able to download them from our web site - http://communication.chass.ncsu.edu/nirt/Home.html.

This was a webcasted workshop. We had people speaking from our site on the campus of NCSU in Raleigh and we had people giving presentations from all over the USA (from Las Vegas, Nevada to New Haven, Connecticut. We had some minor problems but, by and large, it worked and we will post here (soon) a summary of the technical challenges so others can learn from our efforts.

WHAT FOLLOWS is a summary of the presentations.

WORKSHOP

DAY 1

LENNART SJOBERG from Stockholm School of Economics opened the session.
He studies public risk perception of technology (nuclear waste, food, genetically modified food, and nanotechnology). He discussed the roles novelty and dread play in risk variances between expert and public risk determinations. He claims dread trumps novelty in explaining variance. Dread is viewed emotively. Dread involves severity of consequences rather than the emotional items. Generally, dread is related with interfering with nature. He claims social trust = authoritative trust has little relationship with risk determination by publics (0.3 or less). He claims epistemic trust = trust in science is much more relevant. He discussed risk sensitivity – what makes some people more risk sensitive than others and antagonism as a variable. He adds new risks may bring about new aspects that require new variables. He discussed risk targets – people defer to general risk rather than individual risk is assessing rankings. He covered probability neglect and noted affect trumps data on social trust. He warned the instruction in many surveys complicated findings since affect data of dread are affected by whether one internalizes or externalizes dread. He noted substantive experts had similar structure of risk perception as the public which was different from the original work on general experts. These concepts make it important for us to check material on variance assoc. with public and expert risks when examined personally. He added ratings between gender/sexes minimal. He validated effect on social interaction and validation on risk rankings.

SUSANNA PRIEST from UNLV spoke from Las Vegas using video conferencing software.

She claims attitudes toward stem cells are a function primarily in the belief associated with the moral status of the embryo – an ethical risk. She argues risks are not the same and questions: What kind of risks? Do they think narrowly of harm? are very important. She adds we need work on justice issues and distributional variables.

ROB GOBLE from Clark University appeared live.

The bulk of his presentation was associated with importance of contextualization. He challenged us to find a way of defining a hazard when there is so much uncertainty. [We expect more work soon on horizon mapping - Scheufele and I are developing hypotheses in this area]. He added a discussion of banding = recharacterization or reframing the problem as a possible route.

DAN KAHAN from Yale appeared electronically.

His presentation was on public reactions and what risk communicators can do. He discussion the cultural cognition hypothesis and noted biased assimilation/cultural polarization leads the public to attend in a biased ways. He covered cultural credibility heuristics – (trust experts) – generally, the expert individuals will trust are experts individuals perceive share cultural worldview. He covered framing whereby the same general information with a different lead in a newspaper article framing the salience of a specific application impacts perception (framing by lead). He discussed snap intuitive judgment of risk sensitives populations versus risk skepticals and noted the divide widens as they seek out the views. He then connected this finding to some advocacy groups (NGOs) who arouse views by exposure to information to reinforce their predispositions toward nanotechnology resulting in deep-seated resentment such as occurred with nuclear power. He claimed we can manage and counter-act polarization and create an environment open-minded to the best information. He wants a deliberative environment and noted PEN/CCP will release full results of the framing experiments discussed above.

BREAK

DIETRAM SCHEUFELE from the University of Wisconsin appeared live.

He referenced dependent perceptions and discussed framing effects which are extremely strong for ambiguous stimulants. He noted optimistic framing effects w/o understanding the technology. He discussed perceptual filters that shape interpretations (processing) such things as culture, religious beliefs, moral schema. He added a review of the PEW MEDIA study out about 2 weeks ago. One category, the Net-newsers, suggest a shift from traditional news sources on digital media. He speculated on the implications for attenuation and amplification data sets associated with traditionalists. He noted we need to narrow communication gaps in science between population rather than continuing to preach to the choir. He responded to the “marketing of science” indictment. Ethics of marketing science and technology is something that needs to be further investigated.

JOHN STONE from Michigan State appeared live and lively.

He presented a review of his NIRT and addressed how information needed to be pulled-up to policy makers as well as pushed-out to publics. He is using the extension service as a way to move local knowledge up the stream. This project is a good contact for the last phase of the NIRT when we complete focus groups on food and nanotechnology.

MARTIN CLAUBERG from Tennessee appeared via Skype Meeting software.

He discussed a meta-analysis of research on risk. This was an EC Project and everyone is encouraged to check the final report. He discussed a lot of data and the slides/power points will appear on our site and you should go there in a week or so to read them. He noted uncertainty is generated by multiple views by different representatives.

VICKI COLVIN from Rice was live and presented here rather than Friday morning so she could get back to Texas ahead of the hurricane. She covered the unique properties of nanoparticles - magnetic, chemical and optics and called for proactive risk research is associated with horizon scanning. This may involve risk forecasting much like what is used a meteorology.

DAY TWO REPORT FORTHCOMING as well as a technical review of the webcasting experiment.

WORKSHOP THIS THURS. & FRI.

2008-08-26T17:29:00.008-05:00

Just got back from a Gordon Conference in Montana on Science and Technology Policy. Learned a lot about synthetic biology and neurotechnology. As you know, we are not allowed to write about what happened, but I can see some articles on the horizon.

This is not a teaser though.

The purpose of this post is that you can eavesdrop on our workshop since we are webcasting all of it.

This is the address: http://communication.chass.ncsu.edu/nirt/Berube%20Webcast/berubefull.html

The press release follows:

Press Release: 14 August 2008

NIRT – INTUITIVE TOXICOLOGY
AND PUBLIC ENGAGEMENT

NCSU Workshop on
Communicating Health and Safety Risks on
Emerging Technologies in the 21st Century
McKimmon Center, North Carolina State University
Raleigh, NC August 28-29, 2008

This NSF supported workshop is designed to review some findings and develop the ground plan to complete the award (NIRT: Intuitive Toxicology and Public Engagement) in an efficient and productive manner. After the workshop, the presentations will be reexamined to help define variables needed in the first round of quantitative research funded under the grant (a set of modified Delphi rounds involving expert and inexpert samples).

“The primary objectives of this workshop are to isolate the key variables and to produce appropriate instruments with which we can assess public perceptions of the risks of applied nanosciences. The workshop should also provide us with a clearer picture of the predictions of experts, based on the most recent research, of how the public perceives risks and how different modes of communication affect those perceptions.”

We have designed the workshop with presentations in Raleigh at NCSU McKimmon Center and others from remote locations via the web. We are webcasting the entire workshop and we are streaming selected portions from our website as deliverables. Below is the schedule of speakers. Some titles remain in flux but this seems to be the team with whom we will work.

Some NEW work

2008-08-13T10:56:00.004-05:00

Sorry for dropping off like this but I was working on a 100 plus page White Paper on RISK COMMUNICATION. It will be surfacing soon.

In addition, I thought you might want to visit our web pages not that they are up. One is associated wit the NIRT grant (http://communication.chass.ncsu.edu/nirt/Home.html) and the other with the project I am working on at NCSU (http://communication.chass.ncsu.edu/pcost/index.html) .

In addition, we did a report on ALTERNATIVE ENERGY AND NANOTECHNOLOGY. It was designed for the thousands of high school students who are interscholastic debaters. Next year, they are debating US policy toward alternative energy. It can be found and downloaded for free at: (http://communication.chass.ncsu.edu/pcost/Nanotechnology%20and%20Alternative%20Energy.pdf)

Finally, I wrote a book review for PUoS and am recommending the following two books, esp. the first one.

Gardner, Dan, Risk: The Science and Politics of Fear (London: Virgin Books, 2008) 355pp. ISBN 978-1-905264-15-5 £17.99 (hardback).

Briscoe, Simon & Hugh Aldersley-Williams, Panicology: What Are You Afraid Of? Two Statisticians Explain What's Worth Worrying About (and What's Not) in the 21st Century (London: Viking Penguin, 2008). 304 pp. ISBN 978-0-670-91701-3 £18.98 (hardback).

Berube at Nanobio EC-US Task Force on Biotechnology Meeting

2008-06-11T08:12:00.003-05:00

Just got back from Lake Maggione 60 km north of Milan where I had the opportunity to speak on nanobiotechnology from a societal perspective. In summary, my discussion kicked off the list of speakers. I addressed non-nanomedicine applications of nanobiotechnology as instructed by the hosts. My presentation examined nanobio applications in terms of environmental remediation, agricultural production, and human enhancement. In general, I argued that the issues associated with nanobiotechnology would lead to religious warrants in arguments on playing god, unnaturalness, and dehumanization. Dietram Scheufele and I are planning to write an extensive piece for Nature Nano or another source discussing the role of religion and belief in arguments associated with emerging and converging technologies, esp. nanoscience and synthetic biology driven. I will post summaries of the presentations in the following blog. I am still decoding my notes. NONETHELESS, I think the readership will enjoy knowing that societal concerns dominating all the follow-up discussion after day 1, in the hallways, and continued through day 2.

ESPECIALLY TASTY FRUIT

2008-06-04T03:21:00.002-05:00

I had anticipated releasing this work later this year. However, in a public discussion on June 3^rd at a Joint EC-US Task Force on Biotechnology Research (Nanobiotechnology) in Ispra, Italy, I was asked how to avoid public backlash against nanobiotechnology products. I presented earlier that day on the role religion will play in arguments over nanobio products.

Low hanging fruit refers to applications that can come to market within a reasonable time frame with high marketability.

Contagion theory holds that a collapse in one component of an industry ripples throughout the industry infecting others with the collateral public relations damage.

If we invert contagion, we get a coat-tails phenomenon. If a highly positive application occurs in one component of an industry, the positive public relations ripple throughout the industry. This theory was explicated in a recent article written for Jim Baker’s (editor) new Wiley series, Nanomedicine. The claims made were two-fold: first, the public will generally embrace applications in nanomedicine due to intense necrophobia (fear of death) and positively received product entries in the nanomedicine market will ease entrants of product lines from other nanotechnology industry segments. Put simply, public apprehension might be ameliorated as non-nanomedicine products ride on the coat-tails of nanomedicine products.

Associated with this concept is the conversion of consumers into allies in times of trouble. The anchor heuristic has been well documented. In general, the first experience with a set anchors public sentiment positively or negatively depending on the valence of the experience. A negative anchor is more difficult to convert into a positive anchor than the reverse. As such, a positive anchor is optimal. A positive anchor related to experience with a popular product will be the starting point a member of the public will use in examining subsequent experiences.

Illustration: A product (say a treatment for metastatic breast cancer) is introduced by company X. Public response is predictably positive given the mortality and morbidity of this type of breast cancer. In addition, current treatment regimens (chemotherapy and radiotherapy) are particularly problematic. A negative event occurs (say a study linking nanotubes to pancreatic cancer) subsequent to the entry of the nanomedicine product. The reaction from the public should be test the nanotube research against the positive experience with the breast cancer treatment.

This relationship is hardly perfect. For example, the interval between the entry of the product with the positive valence (positive anchor) and the stipulated negative findings from the hypothetical study will affect the power of the anchor and how significant the anchoring phenomenon will have in comparative evaluation. There are more codicils under development for a forthcoming formal publication including a discussion of the ethics of this proposal.

My argument – it behooves the powers that be to fund the development of some “especially tasty fruits” to generate a positive anchor for the field of applied nanoscience/nanotechnology. Expect a more detailed follow-up.
