A positive probability law has a density function of the general form Q ( x )exp(− x 1/λ L ( x )), where Q is subject to growth restrictions, and L is slowly varying at infinity. This law is determined by its moment sequence when λ< 2, and not determined when λ> 2. It is still determined when λ= 2 and L ( x ) does not tend to zero too quickly. This paper explores the consequences for the induced power and doubled laws, and for mixtures. The proofs couple the Carleman and Krein criteria with elementary comparison arguments. 相似文献

Assignment of individuals to correct species or population of origin based on a comparison of allele profiles has in recent years become more accurate due to improvements in DNA marker technology. A method of assessing the error in such assignment problems is présentés. The method is based on the exact hypergeometric distributions of contingency tables conditioned on marginal totals. The result is a confidence region of fixed confidence level. This confidence level is calculable exactly in principle, and estimable very accurately by simulation, without knowledge of the true population allele frequencies. Various properties of these techniques are examined through application to several examples of actual DNA marker data and through simulation studies. Methods which may reduce computation time are discussed and illustrated. 相似文献

In ‘Semantic Foundations for the Logic of Preference’ (Rescher, ed.,The Logic of Decision and Action, University Press, Pittsburgh, 1967), Nicholas Rescher claims that, on the semantics developed in that paper, a certain principle
- call it ‘Q’ turns out to be ‘unacceptable’. I argue, however, that, given certain assumptions that Rescher invokes in that same paper,Q can in fact be shown to be a ‘preference-tautology’, and henceQ should be classified as ‘acceptable’ on Rescher's theory. 相似文献

This study explores the motivational consequences of an incentive device based on standard setting. It is shown that standard setting induces a wealth-seeking manager to undertake decisions that, in the manager's judgment, will improve the position of the owner relative to implementing the standard. Conditions under which it is rational for the owner to allow the manager to choose and implement decisions are discussed. Finally, consideration is given to an alternative incentive mechanism in which the manager's decisions are manipulated through variation of the incentive mechanism. 相似文献

The rapid expansion of coal seam gas (CSG) extraction across Australia has polarized public opinion about the risks, benefits, and the future of the industry. We conducted a randomized controlled experiment to assess the impact of CSG messaging on opposition to the CSG industry. Residents of a major Australian city (N = 549), aged between 21 and 87 years, were randomly assigned to view one of three brief video messages (pro‐CSG, anti‐CSG, or a neutral control) sourced from the Internet. They then completed measures assessing CSG affective associations, perceived risks and benefits of CSG, and degree of opposition to the CSG industry. A subsample of 317 participants also completed the measures of affect, risks, benefits, and opposition two weeks following the initial message presentation. Message type significantly predicted message effects in a pattern consistent with the affect heuristic model, although overall, the message effects were modest in magnitude. Respondents who viewed the anti‐CSG video (relative to the control) reported more negative affective responses to CSG, perceived higher risks, fewer benefits, and greater opposition to the CSG industry. Those who viewed the pro‐CSG video (relative to the control) reported stronger positive affective responses to CSG, perceived more CSG benefits and fewer risks, and expressed less opposition to the industry. The effects persisted over a two‐week interval for the anti‐CSG message, but not for the pro‐CSG message. Our findings suggest that people's risk perceptions and views about the acceptability of CSG are malleable by messaging that targets affective pathways. 相似文献

College is an important time for young adults to establish healthy eating habits since students are at risk for gaining weight during the college years. An emerging area of research is examining the effect of meal-timing, which involves the timing of food intake throughout the day, in an effort to improve satiety and bodyweight. The purpose of this study was to examine the use of meal-timing among a sample of college students and to assess what aspects from an intervention could help them to adhere to meal-timing long term. Participants were randomly assigned to either a daytime group (≤30% total kcals after 5?pm) or a nighttime group (≥50% total kcals after 5?pm). After completing the intervention, almost half of participants (49%) reported they could adhere to meal-timing long-term. Having more resources that support meal-timing are needed to help students potentially achieve a healthy weight and prevent chronic diseases. 相似文献

Few studies have focused on global warming risk perceptions among people in poor and developing countries, who are disproportionately impacted by climate change. This analysis conducts a comprehensive assessment of global warming risk perceptions in India using a national sample survey. Consistent with cultural theory, egalitarianism was positively associated with global warming risk perceptions. In addition, perceived vulnerability and resilience to extreme weather events were also two of the strongest factors associated with global warming risk perceptions. While worry was positively associated with risk perceptions, it accounted for only a small proportion of the variance, unlike studies in developed countries. Finally, the study also collected global warming affective images. The most common responses were “don't know” or “can't say” (25%), followed by “pollution” (21%), “heat” (20%), and “nature” (16%). The study finds that the predictors of global warming risk perceptions among the Indian public are both similar and different than those in developed countries, which has important implications for climate change communication in India. 相似文献

Populist leaders and movements have long adapted their communication practices to fit their media environments. Yet, research on the relationship between media and populism has been limited until recently. This article offers an overview of how media researchers have been identifying populist media and communication practices and investigating ways in which media structures may constrain or enable the growth of populist movements. It discusses three different scholarly frameworks that suggest that social media platforms and shifts in news media may be providing new opportunities for populist messages to circulate more widely. These shifts may be a contributing factor to a recent surge in populism across many countries. Finally, this article raises normative questions about journalistic practices and media policy in response to concerns about right‐wing populist communication practices. 相似文献
