Perceived Risks from Radiation and Nuclear Testing Near Semipalatinsk, Kazakhstan: A Comparison Between Physicians, Scientists, and the Public 总被引:2,自引:0,他引:2
Determining the difference in perception of risk between experts, or more educated professionals, and laypeople is important so that a potential hazard can be effectively communicated to the public. Many surveys have been conducted to better understand the difference between expert and public opinions, and often laypeople exhibit higher perceptions of risk to hazards in comparison to experts. This is especially true when health risk is due to radiation, nuclear power, and nuclear waste. This article focuses on one section of a risk perception survey given to two groups of individuals with a more specialized education (scientists and physicians) and laypeople (villagers) in the Semipalatinsk region of Kazakhstan. All of these groups live near the former Soviet nuclear test site. Originally, it was expected that the scientists and physicians would have similar perceptions of radiation risk, while the public perceptions would be higher, but this was not always the case. For example, when perceptions of risk pertain to the health impacts of nuclear testing or the dose-response nature of radiation exposure, the physicians tend to agree with the laypeople, not the scientists. The villagers are always the most risk-averse group, followed by the physicians and then the scientists. These differences are likely due to different frames of reference for each of the populations. 相似文献

The freeing of financial markets has brought with it increasing sophistication in regulatory regimes. Over time, a succession
of frauds and financial scandals has emphasised some limitations of these complex regulatory schemes. This paper seeks to
address the reasons for the events that have caused concern, and suggests that they are to be found principally in three categories:
(1) the underlying values that drive financial services; (2) the assumptions and values of regulatory regimes, and (3) the
increased opportunities to break or evade the rules. Some possible ways forward are sketched.

In this article, we investigate the potential usefulness of the three-parameter transmuted generalized exponential distribution for analyzing lifetime data. We compare it with various generalizations of the two-parameter exponential distribution using maximum likelihood estimation. Some mathematical properties of the new extended model including expressions for the quantile and moments are investigated. We propose a location-scale regression model, based on the log-transmuted generalized exponential distribution. Two applications with real data are given to illustrate the proposed family of lifetime distributions. 相似文献

Adolescents of Anglo-Celtic, Greek, Italian and Chinese descent attending a wide range of post-secondary institutions in Victoria (mean age = 18 years) were asked about their sexual behaviours, knowledge about AIDS, and social responses to the threat of AIDS. There was evidence of relatively high levels of sexual activity, with some members of all groups engaging in risky sexual behaviour. Anglo-Australians were more sexually active and informed about AIDS, with more equality between the sexes in these respects than the other groups. There was a distinction made between behaviours regarded as safe with regular and casual partners, but the meaning attributed to regular partnership differed. Greek- and Italian-Australian young men endorsed monogamy for their regular partners but not necessarily for themselves, and Anglo-Australians accepted a relationship of shorter duration as regular. Greater knowledge was not related to safer sexual behaviour, but discussion about a regular partner's previous sexual history correlated with more risky sexual behaviour. Overall, risk levels were not high but the casual-regular partner distinction, together with the greater use of relatively unrealistic strategies for dealing with AIDS in association with risky behaviour in the non-Anglo groups, gives cause for concern. 相似文献

Men and masculinity are considered a key factor in changing gender inequality at the transition to parenthood. Prior research on gendered division of parental leave concentrated on fathers’ perspectives. This paper includes perspectives of fathers and mothers who make use of parental leave in different ways and asks how masculinity is jointly constructed, how these constructions are linked to the use of parental leave, and if and how they are oriented towards hegemonic masculinity. The analysis is based on 44 qualitative interviews with 11 Austrian couples before and after birth when decisions concerning parental leave were made. Our case reconstructions reveal that parents considered parental leave a central element of masculinity as long as it suited fathers’ needs and circumstances permitted. The decisions for sharing parental leave were father-centred as both partners valued father’s leave higher than mother’s. 相似文献

How Well-Informed Are Pension Scheme Members on Their Future Pension Benefits? Evidence from Ireland
One part of the policy response in many countries to increasing pension coverage will be greater private provision on the part of individuals. This requires that individuals are well informed about pensions. In this article, we assess levels of knowledge of pensions using a representative sample of older Irish adults. We find that two-thirds of individuals enrolled in pension schemes do not know what amount will be paid out on retirement and/or whether the payments will be in the form of lump sums, monthly payments, or both. One policy implication is the need for increased information to be directed at certain groups, in particular, women and less educated people. More fundamentally, the results suggest that the mandatory elements in pension systems should be extended. 相似文献

Threshold‐free estimation of functional antibody titers of a group B streptococcus opsonophagocytic killing assay 下载免费PDF全文
Luca Moraschini Irene Passalacqua Monica Fabbrini Immaculada Margarit Y Ros Fabio Rigat 《Pharmaceutical statistics》2015,14(3):189-197
Opsonophagocytic killing assays (OPKA) are routinely used for the quantification of bactericidal antibodies in blood serum samples. Quantification of the OPKA readout, the titer, provides the basis for the statistical analysis of vaccine clinical trials having functional immune response endpoints. Traditional OPKA titers are defined as the maximum serum dilution yielding a predefined bacterial killing threshold value, and they are estimated by fitting a dose‐response model to the dilution‐killing curve. This paper illustrates a novel definition of titer, the threshold‐free titer, which preserves biological interpretability while not depending on any killing threshold or on a postulated shape of the dose‐response curve. These titers are shown to be more precise than the traditional threshold‐based titers when using simulated and experimental group B streptococcus OPKA experimental data. Also, titer linearity is shown to be not measurable when using threshold‐based titers, whereas it becomes measurable using threshold‐free titers. The biological interpretability and operational characteristics demonstrated here indicate that threshold‐free titers are an appropriate tool for the routine analysis of OPKA data.

Australian University Students' Views of the Nuclear Arms Race: Comparative and Qualitative Analyses
Jeanette A. Lawrence Philip Jennings Agnes E. Dodds Irene M. Styles 《The Australian journal of social issues》1991,26(3):191-209
Australian university students' views of the nuclear arms race were analysed in two studies. A sample comparison study used Nuclear Arms Race Questionnaire (NARQ) and Position on Nuclear Weapons (PNW) scales to compare university students' views with those of high school students and community groups. University students' views were more strongly anti-nuclear than middle income and Middle European migrant groups, but not more than high school student and church member groups'. Females' attitudes were more strongly anti-nuclear than males. A qualitative analysis of ten university students' formulations of the arms races problem and Australia's involvement revealed the complex dimensions of perceived relationships between global and national interests and personal nuclear issues. Students' solutions were directly related to their formulations of the major aspects of the arms race problem, with six students who represented the nuclear problem in terms of superpower conflict, seeing individuals as powerless to influence solutions. Quantitative trends are interpreted in light of the varied representations of the problem and the association of students' generally anti-nuclear attitudes with lack of involvement in the peace movement. 相似文献
