The development and use of nanotechnology in the food industry have grown steadily. While visions for nanofood suggest that the applications will improve quality and safety, they are also controversial for several reasons including potential health risks coupled with difficulty in assessing low-dosage nanoparticle risks as well as values-based objections. In recent years, debate over nanofoods has sparked inquiry into factors that predict public attitudes and purchase intentions. Such studies have investigated the roles of demographics and sociographics, value predispositions toward (...) science and technology, preferences for natural products, trust in regulatory agencies, scientific knowledge, and media attention. This study assesses the role of each of these factors in shaping public attitudes toward nanofood and improves the predictive models by evaluating concepts from protection motivation theory. We find that incorporating threat and coping appraisals provides the best predictive models of public attitudes and intention to purchase nanofood products. (shrink)

Does national success with an emerging technology require ethical sacrifices? This question is considered through the simultaneous consideration of ethics, investment, and outcomes in the nine jurisdictions that are making the largest investments in nanotechnologies—an important emerging technology. It is found that while ethical environment has no notable effect on pure and applied research, a more positive ethical environment is associated with measures associated with invention and commercialization. In summary, a race-to-the-top supports invention and commercialization of emerging technologies. A critical (...) finding as it suggests that issues such as corruption and regulation could be critical in limiting the extraction of social and economic benefit from emerging technologies (like nanotechnologies).

This paper explores the application of an affective content analysis to a selection of nanotechnology news articles gathered from selected newspapers. Thematic content analyses dominate current efforts to mine large text collections of popular science media; the addition of an affective analysis element can yield useful information to supplement future content analysis efforts. Using Whissell’s Dictionary of Affect in Language , the analysis rates news articles gathered over a twenty-two year period for their pleasantness, activeness, and imagery, determining the mean (...) affective tone in each category for the entire collection, four ‘content themes’ (business, national security, health, and environment), and the change in affective tone over the twenty-two year period these articles represent. Whereas the entire collection analyzed as a whole rates very similarly to the average found for everyday English language use and the ‘content themes’ show similar results, the change in affective tone over the years has been both significant and striking. A sample of results from three years of the twenty-two year period is then qualitatively explored to demonstrate to the reader the connection between the quantitative results of the Dictionary and the qualitative effect of the article’s word use and phrasing. The paper ends with a review of the technique’s success, implications for policymaking and public dialogue, and avenues for future use. (shrink)

The aim of this study is to examine the distribution of news related to nanoscience and nanotechnology published in Turkish newspapers between 2011 and 2018. Nine Turkish newspapers selected using criterion sampling were investigated and the document analysis method was used to analyze them. The electronic archives of the newspapers were used to collect data and the word “nano” was used as a keyword. The obtained data were analyzed with the content analysis technique. While analyzing the news stories, categorization was (...) performed according to four main variables: distribution by years, the newspaper section, the approach in the content of the news stories, and the content of the news stories. As a result, it was seen that there has been an increase in the number of nano-news stories in Turkish newspapers over the years, the news stories are mostly included in the “local” section of the newspapers, and the general approach is positive. In the categories formed according to the content of the news stories, the number of news stories related to the production and commercial applications of nanotechnology was higher compared to the others. In an international comparison, it should also be mentioned that the topic of risk plays a subordinate role in the newspapers examined. (shrink)
