Characterisation results of the complex permittivity of select dielectric cooling fluids at room temperature and over a broad frequency range found using a low-loss printed circuit board microstrip ring resonator technique are presented. ANSYS HFSS, a finite-element full-wave electromagnetic simulation environment, was used to fit the simulated insertion loss to the calibrated measurements of the microstrip ring resonator in air and submerged in different dielectric fluids. The resulting frequency-dependent relative permittivity and loss tangent are provided up to 50 GHz for three dielectric cooling fluids: 3M™ Novec™ 649, 3M™ Novec™ HFE-7100 and 3M™ Fluorinert™ FC-72.

A comparison of accepted nutritional advice with actual American dietary practice suggests that many people fail to eat well in spite of well-documented health consequences. Popular culture often labels the worst offenders as lacking in \"self-control,\" and many blame the aggressive advertising campaigns of the fast-food and snack-food industries for manipulating consumers into poor diets, but these conclusions are not easily reconciled with a neoclassical approach to economic decision theory. This essay considers the consumer's \"diet problem\" in light of emerging evidence from the medical and behavioral sciences. In particular, it is argued that human evolution in the distant past resulted in an elegant solution to this problem (of search for a suitable diet in an uncertain environment), which any neoclassical economist would recognize. In modern environments, however, the signals that formerly provided information in the consumer's search problem are subject to manipulation by food-producing firms. Confirmation by molecular biologists that many human responses to these signals are firmly encoded in our genes suggests a need to re-evaluate the welfare economics of the food industry.

Purpose - This paper aims to explore the diverse and complementary resistance and waste-reduction practices adopted by UK-based New Consumption Communities, and whether such behaviours empower them to achieve their environmental and social goals.Design methodology approach - The methodology can be broadly classified as critical ethnography, which acknowledges the researcher's own subjectivity, how the informants are treated and represented, and the study's wider context. A participant-observer role is employed and six distinct New Consumption Communities are explored.Findings - It is suggested that through their resistance and empowerment, as well as a reconnection to production, the communities are able to implement alternatives to the wasteful practices of mainstream consumption behaviour, and achieve (partial) autonomy from the hegemonic forces of the market.Originality value - This paper's original perspective on waste is not limited to a small group of consumers, and thus should interest marketers and policy makers engaged in the advancement of sustainability and green marketing.

The 56th Annual Conference of the American Association for Public Opinion Research was held at the Hilton Montral Bonaventure in Montreal, Quebec, Canada, May 17-29, 2001. The conference theme was 'Making Connections.' Some 800 public opinion researchers accepted the invitation to meet colleagues and friends and to participate in the interdisciplinary program.

This article examines the diversification of the news media in Korea since the 1990s as a result of deregulation and democratization. It also examines the impact of media diversity on the public's use patterns and its trust in the media, and evaluates the current state of freedom of the press in Korea. Contrary to scholarly research, which holds that freedom of the press has increased significantly over the last decade, this study found that the Korean press still faces a variety of restraints despite improvements in a few areas.

Background: Prenatal screening for chromosomal abnormalities is routinely offered to all pregnant women who present for care by their 20th gestational week. Not all women, however, choose to undergo one of these tests, and choice of which test(s) to undergo also vary. The reasons for variation in screening test behavior have not been fully explored. Methods: We examined the psychometric properties of scales developed to measure factors related to prenatal screening using data collected as part of a survey of 448 racial/ethnically diverse pregnant women. These women were consecutively recruited from prenatal care clinics when they were between their 12th and 20th week of pregnancy. The Theory of Reasoned Action was used to develop to measures of attitudes toward and beliefs about prenatal screening. All items were subjected to factor analysis. Scales identified in the factor analysis were then subjected to reliability analysis. All analysis was conducted for the entire study group as well as separately for each racial/ethnic group. Results: Six scales emerged: who makes medical decisions, fatalism, health care trust, value of screening, fear of screening and value of pregnancy. All scales had adequate reliability when the analysis was conducted for the entire study group; however there were differences in reliability across racial/ethnic group. Conclusions: Because of these between group differences comparisons of racial/ethnic group may be difficult to interpret and potentially lead to erroneous conclusions.

A personal profile of Everett Caril Ladd, a key figure in the public opinion research community, is presented.

In an address to the American Association for Public Opinion Research (AAPOR), the association's president attributes the prevailingair of tentative hesitation, caution, and uncertainty to the sudden emergence of the World Wide Web. One important unknown is the future of WebTV and other similar matings of TV and Web in a single family-entertainment-center appliance. In an address to the American Association for Public Opinion Research (AAPOR), the association's president attributes the prevailing air of tentative hesitation, caution, and uncertainty to the sudden emergence of the World Wide Web. One important unknown is the future of WebTV and other similar matings of TV and Web in a single family-entertainment-center appliance. A rapid discovery of the World Wide Web is reflected in the programs of the association's annual conferences. This year's conference includes a plenary session, 9 papers, and one 7-person panel devoted to the Internet, the Web, or both. Clearly, in only the past 3 years, the World Wide Web has elbowed its way from a virtual unknown among most AAPOR members to the very heart of annual conference activities.

The American Association for Public Opinion Research (AAPOR) held its 53rd conference May 14 -17, at the Marriott Pavilion Downtown in St. Louis, Missouri. Gordon Black, president of Harris Black International, said that the Internet is having the fastest adoption rate of any technology in history and predicted that it will become a replacement technology, just as the telephone has replaced face-to-face interviewing. The American Association for Public Opinion Research (AAPOR) held its 53rd conference May 14 -17, at the Marriott Pavilion Downtown in St. Louis, Missouri. Official registration was 566, including 77 new members. The 3 short courses at the conference attracted a record enrollment of 189. In keeping with the tradition for conferences held during even-numbered years, the conference site was shared by the World Association for Public Opinon Research. The Thursday night plenary, organized and chaired by Mark Schulman was The Market Research Industry in 2010, and featured 3 presidents from major market research firms. Sol Dutka of Audits and Surveys expressed great concern that bad research will continue to drive out good research and urged the audience to study and reaffirm AAPOR's standards.

The growing entrenchment of the technology of public opinion assessment in the past 50 years has had a major impact on the conceptions of what 'public opinion' really means. In an earlier era, the term often referred to the views held by a few community notables who kept themselves informed and pondered on public matters at length. When the public polling industry began, however, it chose to define public opinion on the basis of 'one person, one vote.' The polling industry's concept of public opinion has gained wide acceptance, as witnessed by the increasing willingness of politicians to pay to have polls conducted. Despite this trend, it occasionally has been demonstrated that public opinion as measured by sample surveys and actual public opinion as demonstrated in political arenas can sometimes diverge remarkably. There is some question as to whether the US is better off in an era in which politicians simply follow public opinion rather than exercise leadership.
