The extant literature on the death row process and its relationship to inmate execution is limited. One way to interpret the association is to examine those groups constituting the death row community. In this study, we argue for the existence of an execution community composed of several related membership groups: the prisoner awaiting death, the inmate's family, the correctional personnel working the unit, and the victim and the victim's loved ones. In order to assess whether, and to what extent, a death row community in fact exists, we rely on several principles found in community psychology. By grafting a \"sense of community\" model onto the behavior of those membership groups identified, we demonstrate how the death row community phenomenon cohesively operates. We conclude by tentatively exploring the implications of our analysis for purposes of future research on the execution experience and life on death row. 相似文献

Research on vocal expressions of emotion indicates that persons can identify emotions from voice with relatively high accuracy rates. In addition, fairly consistent vocal profiles for specific emotions have been identified. However, important methodological issues remain to be addressed. In this paper, we address the issue of whether there are individual differences in the manner in which particular emotions may be expressed vocally and whether trained speakers’ portrayals of emotion are in some sense superior to untrained speakers’ portrayals. Consistent support was found for differences across speakers in the manner in which they expressed the same emotions. No accompanying relationship was found between differences in expression and accuracy of identification of those expressions. Little evidence for the superiority of trained speakers was found. Implications of these findings for future studies of vocal expressions of emotion, as well as our understanding of emotions in general, are discussed. 相似文献

This paper reports the results of a controlled field experiment in which voice communication was introduced into an existing online community (online gaming guilds within the popular game “World of Warcraft”), comparing a mix of voice and text with text only. Quantitative results suggest increases in liking and trust due to the addition of voice, as well as insulation from unexpected negative impacts of text‐only play. The findings are discussed with respect to social capital, cyberbalkanization, and the general computer‐mediated communication literature, with special attention paid to social information processing theory. 相似文献

Pragmatists (such as William James) recommend optimism as a successful strategy, and recent psychological research has confirmed its value. But optimism comes at a price: optimists are less accurate in their assessments and expectations than are pessimists. Thus optimism 'proves itself to be good in the way of belief', and by pragmatic standards should count as true; but that makes the accuracy costs of optimism invisible (the problem is only exacerbated by Rorty's recommendation that pragmatists stop speaking of truth altogether). The problem prevents pragmatists from offering a Darwinian explanation of why pessimism survives, and also blocks any pragmatist account of the well-documented and highly successful exploratory behavior of many animal species. 相似文献

Recent research has shown that unfamiliar face matching from both high‐ and low‐quality closed circuit television video images to photographs is highly prone to error, even when viewpoint and expression are matched as closely as possible. The current experiments made use of a filmed, staged reconstruction of a bank raid that was captured on CCTV and on high‐quality broadcasting video. Experiment 1 tested the ability of members of the public to match actors captured on CCTV to photo‐spreads containing similar‐looking distractors. Further experiments, each testing different groups of subjects, investigated matching ability using both high‐quality photographs (Experiment 2) and broadcast‐quality video material (Experiment 3). Experiment 3 also investigated the effect of disguising hairstyle, and varied whether or not the target was present in the photo line‐up. The results of these experiments confirm those of previous work, that matching the identity of unfamiliar faces is highly fallible, even when high‐quality footage is used. Experiments 4 and 5 tested matching ability using two‐alternative forced‐choice and single‐item verification tasks. Performance remained highly error‐prone even with the simplest question asked. The legal implications of the results are discussed. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Two experiments are reported that assess how well the identity of highly familiar (famous) faces can be masked from short naturalistic television clips. Recognition of identity was made more difficult by either pixelating (Experiment 1) or blurring (Experiment 2) the viewed face. Participants were asked to identify faces from both moving and static clips. Results indicated that participants were still able to recognize some of the viewed faces, despite these image degradations. In addition, moving images of faces were recognized better than static ones. The practical and theoretical implications of these findings are discussed. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Because workplace learning research may entrench existing power relations rather than empower workers, educators should examine workplace learning within a broad economic and social context and take up their historic responsibilities to advocate socially responsible adult education. 相似文献

Discussions of the origin of life usually assume that there is a specific event, however improbable, by which dead matter became a living entity. Naturalistic accounts, although in seeming opposition to theistic explanations of the apparent design of even the simplest cells, often share the assumption that there is a specific line to be crossed. If the problem is recast as one of a process of emergence of biochemistry from protobiochemistry, which in turn emerged from the organic chemistry and geochemistry of primitive earth, the resources of the new sciences of complex systems dynamics can provide a more robust conceptual framework within which to explore the possible pathways of chemical complexification leading to life. In such a view the emergence of life is the result of deep natural laws (the outlines of which we are only beginning to perceive) and reflects a degree of holism in those systems that led to life. Further, there is the possibility of developing a more general theory of biology and of natural organization from such an approach. The emergence of life may thus be seen as an instance of the broader innate creativity of nature and consistent with a possible natural teleology. 相似文献
