Questions persist regarding the robustness of cross-sectional estimates of effects of variables that are themselves endogenous to the participation process. On one hand, the consequences of working on a campaign have interesting implications for democratic society. Less benign, however, is the possibility that failure to control for reciprocal processes leads to biased estimates of the causes of campaign participation. I use a panel of Democratic and Republican contributors interviewed following each of the past three presidential elections (1996, 2000, and 2004) to explore the relationships between campaign participation and three variables typically parameterized as predictors of participation: receiving a contact, ideological extremism, and strength of party identification. The effect of strength of party identification on campaign participation proves robust; however, I find that nearly all of the associations between contacts and participation and ideological extremism and participation appear to extend from, not into, participation and past participation.

Research in recent times has clearly demonstrated that violence is predictable and preventable; however, the primary prevention of abusive and violent behavior will not occur without personal, interpersonal, and social change. This article reviews the empirical research supporting hypotheses for primary prevention of many risks associated with children becoming abusive.  相似文献

Clothing damage analysis is an integral part of the examinations carried out in sexual assault type cases. This analysis can be used to corroborate different versions of events and is at its most powerful in elucidating false allegation cases and consent cases. The purpose of this study was to determine to what extent people with varying levels of forensic awareness, experience and training could correctly carry out damage analysis. Two participant groups were asked to take part in this study. Group A ('forensic group') comprised participants at a forensic science conference, and Group B ('student group') comprised students undertaking a degree course in Forensic Science. Each group was given a practical workshop consisting of a lecture outlining common fabric types and general features observed in different damage types. Each participant was subsequently shown 25 pieces of 'damage' and asked to identify both the type of fabric construction (knit or weave) and the type of damage (cut, tear, rip, wear and tear). The ability to identify fabric construction and damage types varied within the two groups studied and across the groups. The forensic group performed better both in fabric and damage assessment than the student group. This paper suggests a systematic approach to clothing damage analysis to maximise the benefits that can be obtained from this area of forensic science and to minimise the subjectivity within the field.  相似文献

The “cloud” is not new, and its roots go back to the original plans for computing from the 1950s. Now that computing is moving back to the original cloud-based models that were envisioned more than 60 years ago, with it, consumers are realizing the increases in security and safety that accompany the move to centralized servers. Yet the perception of “trust” in this context is often still formed by views that people have from their use of computers over the past two decades, which is localized in nature (“if I can see it, I can control it”). This view is based on perception more than fact. Our paper discusses different views of trust in other contexts (such as banking and travel) and concludes that users of cloud computing should recast their view of trust in a similar way that consumers of banking and travel have changed their perceptions of trust in the last 100 years.  相似文献

A 48-year-old-woman was struck dead by lightning on October 24, 2010, in Pretoria, South Africa. The cause of death was due to direct lightning strike. Examination showed secondary missile injury on her legs. This secondary missile (shrapnel) injury was caused by the lightning striking the concrete pavement next to her. Small pieces of concrete were located embedded within the shrapnel wounds. This case report represents the first documented case of secondary missile formation (shrapnel injury) due to lightning strike in the literature.  相似文献

Objectives

The purpose of this study is twofold. First, this study assesses the extent to which self-control and maternal attachment mutually influence one another. Second, it investigates whether this process continues to occur during adolescence. To date, studies of the etiology of self-control have yet to adequately address these issues, despite the fact that a number of theoretical perspectives emphasize the reciprocal nature of the parent-child relationship.

Methods

The current study seeks to shed light on these issues by examining the relationship between self-control and maternal attachment using structural equation modeling for eight waves of data spanning a period of time that encompasses early childhood through middle adolescence.

Results

The results yield two findings bearing on the adequacy of Gottfredson and Hirschi??s model of self-control development. First, measures of self-control and maternal attachment were found to mutually influence one another during childhood. Second, these effects were reduced to nonsignificance during adolescence.

Conclusions

This study finds that self-control emerges during childhood in a complex manner in which it both shapes and is shaped by parental attachment.  相似文献

Exposure to violence and traumatic events during childhood has long been associated with poor physical and psychological health during adulthood. Very few studies, however, have taken steps to understand the immediate relationship between exposure to intimate partner violence (IPV) and physical health problems in young children. In this study, we examined the mother-reported physical health problems of 102 preschool-age children who have been exposed to IPV. We found that children exhibiting more traumatic stress symptoms displayed fewer total health problems; however, gastrointestinal problems and asthma were related to poor psychological adjustment. We also found that preschool-age girls were more likely to display health problems than boys. Future studies of the physical health consequences of exposure to IPV in young children would benefit from examinations of specific changes in physiological processes to draw conclusions about the effects of violence on immune system functioning and physical health.  相似文献

The substantial increase in the enrollment of women in batterer intervention programs (BIPs) over the past 30 years has greatly outpaced research on women who perpetrate intimate partner violence (IPV). As a result, it is unknown whether existing programs, which were originally designed to treat male perpetrators, are effective at preventing recidivism among women. Recent research shows that men who perpetrate IPV may also aggress against nonintimate partners, children, and animals, and that the reach of their aggressive tendencies has implications for treatment. Conducting similar investigations on women who perpetrate IPV may help to inform treatment delivery in BIPs. This study examined the prevalence of adulthood animal abuse perpetration and its association with psychological and physical IPV perpetration in a sample of women arrested for domestic violence (N = 87). Seventeen percent (n = 15) of the women committed at least one act of animal abuse since the age of 18, in contrast to the 0.28% prevalence rate reported in the general population. The overrepresentation of animal abuse in this sample was consistent with that of men arrested for domestic violence. Furthermore, women who reported committing animal abuse as an adult showed moderately higher rates of psychological aggression and physical assault perpetration against their partners, relative to women who did not report animal abuse. Implications for future research are discussed.  相似文献

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault.  相似文献
