Use of Postmortem Temperature Decay Response Surface Plots of Heat Transport in the Human Eye to Predict Time of Death

A finite element heat transfer model of the human eye was previously constructed and applied to experimental postmortem temperature decay curves collected in eyeballs of ten human bodies. The model was applied in the early postmortem period of 0–24 h under conditions of natural convection–radiation. Based upon this previous model, response surfaces for postmortem temperature decay were constructed based upon variable ranges of the natural convective–radiation heat transfer coefficient from 7–13 W/m² K, ambient temperatures of 10–33°C, and times of 0–24 h. Mathematical equations to describe these response surfaces have been developed. This response surface method is demonstrated for use by coroners/medical personnel to estimate time of death from recorded field temperature data collected over a 30‐min period. Sensitivity of the model to small changes in the key variable of ambient temperature is explored. The response surface model is applied to two cases of previously collected experimental eyeball temperature data. This response surface model method is only valid for constant surrounding temperatures, conditions of natural convection, no radiation effects, and postmortem times of 0–24 h.     

Of guns and geese: a meta-analytic review of the ‘weapon focus’ literature

Abstract

Weapon focus is frequently cited as a factor in eyewitness testimony, and is broadly defined as a weapon-related decrease in performance on subsequent tests of memory for those elements of an event or visual scene concurrent to the weapon. This effect has been attributed to either (a) physiological or emotional arousal that narrows the attentional beam (arousal/threat hypothesis), or (b) the cognitive demands inherent in processing an unusual object (e.g. weapon) that is incongruent with the schema representing the visual scene (unusual item hypothesis). Meta-analytical techniques were applied to test these theories as well as to evaluate the prospect of weapon focus in real-world criminal investigations. Our findings indicated an effect of weapon presence overall (g= 0.53) that was significantly influenced by retention interval, exposure duration, and threat but unaffected by whether the event occurred in a laboratory, simulation, or real-world environment.     

Children's truthful and deceptive testimonies: How camera perspective affects adult observers’ perception and assessment

Abstract

This experimental study investigates adults’ perception and assessments of children's testimonies as a function of camera shot (close-up shot vs medium shot vs long shot) and camera focus (child only vs child and interviewer). Truth-telling and lying children were interviewed and videotaped simultaneously by four cameras, each taking a different visual perspective (‘close-up shot/child only’, ‘medium shot/child only’, ‘medium shot/child and interviewer’, ‘long shot/child and interviewer’). Mock jurors (N=256) watched the videotaped testimonies and rated their perception of the children's statement and appearance, and assessed the children's veracity. Children seen in long shot were perceived as more neutral and relaxed, and children seen in close-up were perceived as having to think harder. The adult's deception detection accuracy was at chance level. The results suggest that legal policy-makers should consider the outcome of psycho-legal research on camera perspective when establishing and/or reforming standards for police interviews and courtroom procedures.     

Wisdom or Indifference? The Principles of Representative Government in the Eyes of the French Voters

This contribution attempts to assess qualitatively the current views of ordinary French citizens about political representation in general and their MPs in particular. In contrast to the Tocquevillian idea of an unequivocal egalitarian claim rising from the people, the results of the present study support the view that citizens tend to adopt both democratic and aristocratic principles in their perceptions of political representation. General support for the electoral procedure captures such ambiguity as elections are not only legitimate on democratic grounds (the egalitarian civic participation) but also on aristocratic grounds (the selection of the best). This study follows an original method involving analysis of discussions from 11 focus groups within French constituencies in 2010–11. The results of an experimental design comparing various kinds of elected position (parents' representatives, workers' representatives, MPs and the President of the Republic) are presented and discussed.     

Choosing your own Boss: Variations of Representation Foci in Mixed Electoral Systems

Members of parliament are privileged agents. They can choose who to regard as their principal: the entire nation, a particular electoral district or a political party. Focusing on two countries with mixed electoral systems, Romania and Hungary, the article documents the dominance of the electoral logic of role-formation over the constraints of legislative organisation and the influence of socialisation. The focus of representation is found to be only modestly influenced by the degree of the embeddedness of MPs in political structures and hierarchies. The association of the seat with a particular territorial unit, on the other hand, has a robust effect even when this association originates in the political environment and not in formal rules. Finally, the psychological effect of losing a Single Member District is also found to influence how MPs perceive their representative role.     

财产纠纷的若干问题

近年来非婚同居的现象越来越普遍,由非婚同居引发的各种纠纷也越发凸显,尤其是财产纠纷更为突出.对于我国非婚同居的财产问题,我国的现行规定则是少而又少,缺乏实际意义上的操作性,且过于原则化,不足以应对在实践中产生的各种各样的纠纷.法律应当做出必要的规范,以统一司法认识,对于同居予以立法规制,可以更好地保护公民个人的合法权益,特别是保护弱者的权利不受侵害.     

Consumers as Collaborators in Research and Action

SUMMARY

This paper discusses the role of consumers as collaborators in disability research conducted in the community. A comprehensive model of participatory action research is described and illustrated with research and training projects conducted in a collaborative arrangement between researchers and a Consumer Empowered Team. The paper describes how adherence to the model could be conducted in actual research and training settings and produce outcomes valued by the consumers at whom the interventions were targeted. The advantages and caveats to using the consumer as collaborator approach are discussed.     

The Meaning of Dating Violence in the Lives of Middle School Adolescents

Abstract

This article reports qualitative findings of seven focus groups that illuminate the phenomenon of dating and dating violence from the perspective of the young adolescent. This study was part of a larger intervention project, “An Arts-Based Initiative for the Prevention of Violence Against Women and Girls,” a collaboration of the Centers for Disease Control and Prevention and Johns Hopkins University, School of Nursing. Concepts of interest included: dating norms, ecological factors, elements of healthy and unhealthy relationships, and prevention strategies. Four themes emerged: respect versus disrespect, influence of friends, cost and benefit of sexual activity and violence as an acceptable response. The implications of this data highlight the need for school personnel to increase their awareness and understanding of the challenges middle school youth face. Dating violence prevention programs should be designed accordingly.     

Lead Theft—A Study of the “Uniqueness” of Lead from Church Roofs

In the United Kingdom, theft of lead is common, particularly from churches and other public buildings with lead roofs. To assess the potential to distinguish lead from different sources, 41 samples of lead from 24 church roofs in Northamptonshire, U.K, have been analyzed for relative abundance of trace elements and isotopes of lead using X‐ray fluorescence (XRF) and inductively coupled plasma mass spectrometry, respectively. XRF revealed the overall presence of 12 trace elements with the four most abundant, calcium, phosphorus, silicon, and sulfur, showing a large weight percentage standard error of the mean of all samples suggesting variation in the weight percentage of these elements between different church roofs. Multiple samples from the same roofs, but different lead sheets, showed much lower weight percentage standard errors of the mean suggesting similar trace element concentrations. Lead isotope ratios were similar for all samples. Factors likely to affect the occurrence of these trace elements are discussed.     

关于刑事诉讼构造的再研究

刑事诉讼原理论基于刑事诉讼构造论,在对刑事诉讼构造细化的基础上,结合刑事诉讼价值、刑事诉讼职能、刑事诉讼目的等刑事诉讼基本范畴,形成一套完整的理论结构。其理论意义在于将原本分散的刑事诉讼基本范畴有机结合起来,便于法学研究者更好地寻找其之间的关系和相互影响下的效果。刑事诉讼构造理论是一项强大的理论武器,其作用不局限于比较法上,其对于刑事诉讼法学体系的完善和梳理有着重要意义。同时完整而符合逻辑的刑事诉讼构造理论也可以更好地指导立法者按照科学的立法规律制定和修改法律。
