Prior research indicates that altering the perspective from which a videotaped confession is recorded influences assessments of the confession's voluntariness. The present study examined whether increasing decision makers' sense of accountability attenuates this biasing effect of camera perspective. Participants in a high-accountability (but not a low-accountability) condition were told that they would have to justify their judgments concerning the voluntary status of a video-taped confession to a trial judge. Although supplementary measures indicated that high-accountability participants processed information contained in the video-taped confession more carefully and thoroughly, the camera perspective bias persisted. This result adds to a growing body of work indicating that the criminal justice system needs to be seriously concerned with how it acquires and utilizes videotaped confession evidence. 相似文献

In honor of the 60th anniversary of SPSSI's founding, this issue examines the ascendence of psychological expertise in American society. After World War II, psychology grew as the public accepted the illuminating power and social benefits of psychologists' expert knowledge. In that period, four problems confronted psychological experts as their numbers and influence grew. First, they needed ideas and methods that were new and superior to common sense. Second, experts needed to appear both relevant and objective. Third, psychologists needed to forge alliances with those who held social power in the settings in which they wished to operate. Finally, experts needed to balance the roles of social critic and social engineer. 相似文献

This paper concentrates on the recent controversy over the division between sex and gender and the troubling of the binary distinctions between gender identities and sexualities, such as man and woman, heterosexual and homosexual. While supporting the troubling of such categories, I argue against the approach of Judith Butler which claims that these dualities are primarily discursive constructions that can be regarded as fictions. Instead, I trace the emergence of such categories to changing forms of power relations in a more sociological reading of Foucault's conceptualization of power, and argue that the social formation of identity has to be understood as emergent within socio-historical relations. I then consider what implications this has for a politics based in notions of identity centred on questions of sexuality and gender. 相似文献

Predictive distributions are developed and illustrated for prediction in some Poisson errors in variables models. Two different situations in which multiplicative treatment effects are appropriate are considered within the context of predicting counts of road accidents. Hierarchical prior structures are investigated, and numerical integration and Gibbs sampling routines are used to derive the predictive and posterior probabilities. Examples of analyses are provided with data from road accidents in Sweden. 相似文献

Infant crying and night waking are common concerns for parents, costly problems for health services and may trigger infant abuse or lead to serious child disturbances. Parents are given contradictory advice on how to manage infant crying and sleeping, indicating the need for evidence‐based guidance. This review of recent research draws distinctions between infant crying and sleeping problems, between the problem identified by parents and the infant behaviour underlying the problem, between different types of crying behaviour and their causes, and between the types of cases which present at different ages. It proposes that the two main approaches to parenting advocated by baby‐care experts, ‘infant‐demand’ and ‘structured’ parenting, have different benefits, and costs. Comparative studies have found that infant‐demand parenting is associated with low amounts of fussing and crying in the first three months of age, but with night waking which continues beyond three months. Randomised controlled trials have provided evidence that structured parenting leads to more overall fussing and crying during the first three months, but reduced night waking and crying after that. The findings are translated into recommendations for preventing and treating infant crying and sleeping problems, for policy debate, and for further research.

Without in any way denying that there are forces for stability, I want to state, as strongly as I can, my conviction that change is now more rapid, more complex and more pervasive than ever before in human history. There are forces loose in the world, particularly in the ‘post-industrial society’ of the United States, that go far beyond the youth movement in creating change. As a result, it is utterly unrealistic to pretend that business can continue to plan its strategies in the traditional mode. 相似文献

Methods for exploring treatment effect heterogeneity in subgroup analysis: an application to global clinical trials

Multi‐country randomised clinical trials (MRCTs) are common in the medical literature, and their interpretation has been the subject of extensive recent discussion. In many MRCTs, an evaluation of treatment effect homogeneity across countries or regions is conducted. Subgroup analysis principles require a significant test of interaction in order to claim heterogeneity of treatment effect across subgroups, such as countries in an MRCT. As clinical trials are typically underpowered for tests of interaction, overly optimistic expectations of treatment effect homogeneity can lead researchers, regulators and other stakeholders to over‐interpret apparent differences between subgroups even when heterogeneity tests are insignificant. In this paper, we consider some exploratory analysis tools to address this issue. We present three measures derived using the theory of order statistics, which can be used to understand the magnitude and the nature of the variation in treatment effects that can arise merely as an artefact of chance. These measures are not intended to replace a formal test of interaction but instead provide non‐inferential visual aids, which allow comparison of the observed and expected differences between regions or other subgroups and are a useful supplement to a formal test of interaction. We discuss how our methodology differs from recently published methods addressing the same issue. A case study of our approach is presented using data from the Study of Platelet Inhibition and Patient Outcomes (PLATO), which was a large cardiovascular MRCT that has been the subject of controversy in the literature. An R package is available that implements the proposed methods. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Relative risks are often considered preferable to odds ratios for quantifying the association between a predictor and a binary outcome. Relative risk regression is an alternative to logistic regression where the parameters are relative risks rather than odds ratios. It uses a log link binomial generalised linear model, or log‐binomial model, which requires parameter constraints to prevent probabilities from exceeding 1. This leads to numerical problems with standard approaches for finding the maximum likelihood estimate (MLE), such as Fisher scoring, and has motivated various non‐MLE approaches. In this paper we discuss the roles of the MLE and its main competitors for relative risk regression. It is argued that reliable alternatives to Fisher scoring mean that numerical issues are no longer a motivation for non‐MLE methods. Nonetheless, non‐MLE methods may be worthwhile for other reasons and we evaluate this possibility for alternatives within a class of quasi‐likelihood methods. The MLE obtained using a reliable computational method is recommended, but this approach requires bootstrapping when estimates are on the parameter space boundary. If convenience is paramount, then quasi‐likelihood estimation can be a good alternative, although parameter constraints may be violated. Sensitivity to model misspecification and outliers is also discussed along with recommendations and priorities for future research. 相似文献
