Research confirms the risk of victimization faced by women who attend the nation's universities. While stalking began to receive heightened attention in the 1990s, relative to other types of victimization, research regarding college women's stalking experiences is in its infancy. In particular, relatively little is known about victim acknowledgement of stalking and the process whereby victims decide to report to police. Drawing upon data from 1,010 female university students, this study provided important advances in understanding stalking-related victimization for college women, highlighting the influences that fear, offender relationship, types of behaviors involved, and other victimization experiences have on victim acknowledgement and police reporting. Findings offered important advancements in defining a “classic stalking case.” This study had implications for university and public policymakers, educators, and police officers who could benefit from improved understanding of women's perceptions of stalking and their formal help-seeking behavior in response to stalking-related behavior.  相似文献

This paper focuses on potential hazards and risks to forensic anthropologists while working in the field and laboratory in North America. Much has changed since Galloway and Snodgrass published their seminal article addressing these issues. The increased number of forensic practitioners combined with new information about potential hazards calls for an updated review of these pathogens and chemicals. Discussion of pathogen hazards (Brucella, Borrelia burgdorferi, Yersinia pestis, Clostridium tetani and West Nile virus) includes important history, exposure routes, environmental survivability, early symptoms, treatments with corresponding morbidity and mortality rates, and decontamination measures. Additionally, data pertaining to the use of formaldehyde in the laboratory environment have resulted in updated safety regulations, and these are highlighted. These data should inform field and laboratory protocols. The hazards of working directly with human remains are discussed in a companion article, “An Update on the Hazards and Risks of Forensic Anthropology, Part I: Human Remains.”  相似文献

Legislators' private financial holdings affect policy decisions. Due to financial self‐interest, we theorize that legislators whose personal investment portfolios include equities from firms affected by proposed policies vote for legislation that benefits those firms. We also theorize that legislators with greater personal exposure to equity investments support policies that benefit equities markets generally. We create a novel data set of legislators' personal stock investments and examine major congressional actions since the 1990s on financial deregulation and market intervention. US House members who own stocks in firms who benefit from financial deregulation vote for deregulation. House members with greater exposure to financial and automotive stocks support the financial and auto bailouts, respectively. General exposure to equities markets is also associated with support for key legislation boosting markets. The normative implications are significant, as legislators' private interests influence decisions in the public sphere.  相似文献

Machine learning models, especially ensemble and tree-based approaches, offer great promise to legislative scholars. However, they are heavily underutilized outside of narrow applications to text and networks. We believe this is because they are difficult to interpret: while the models are extremely flexible, they have been criticized as “black box” techniques due to their difficulty in visualizing the effect of predictors on the outcome of interest. In order to make these models more useful for legislative scholars, we introduce a framework integrating machine learning models with traditional parametric approaches. We then review three interpretative plotting strategies that scholars can use to bring a substantive interpretation to their machine learning models. For each, we explain the plotting strategy, when to use it, and how to interpret it. We then put these plots in action by revisiting two recent articles from Legislative Studies Quarterly.  相似文献

Leadership targeting has become a key feature of current counterterrorism policies. Both academics and policy makers have argued that the removal of leaders is an effective strategy in combating terrorism. However, leadership decapitation is not always successful, and existing empirical work is insufficient to account for this variability. As a result, this project answers three primary questions: (1) Under what conditions does leadership decapitation result in the dissolution of a terrorist organization?; (2) Does leadership decapitation increase the likelihood of organizational collapse beyond the baseline rate of collapse for groups over time?; and (3) In cases where decapitation does not result in group collapse, to what extent does it result in organizational degradation and hinder a group's ability to carry about terrorist attacks? I develop a dataset of 298 incidents of leadership targeting from 1945–2004 in order to determine whether and when decapitation is effective. First, I identify the conditions under which decapitation has been successful in bringing about organizational decline. The data show that a group's age, size, and type are critical in identifying when decapitation will cause the cessation of terrorist activity. As an organization grows in size and age, it is much more likely to withstand the removal of its leadership. Organizational type is also significant in understanding the susceptibility of an organization to decapitation. Ideological organizations are most likely to experience a cessation of activity following the removal of leader, while religious organizations are highly resistant to leadership decapitation. Second, I determine whether decapitation is an effective counterterrorism strategy that results in organizational collapse. The data show that decapitation does not increase the likelihood of organizational collapse beyond a baseline rate of collapse for groups over time. Organizations that have not had their leaders removed are more likely to fall apart than those that have undergone a loss of leadership. The marginal utility of decapitation is negative for many groups, particularly for larger, older, religious, and separatist organizations. Finally, I look at the extent to which decapitation results in organizational degradation and hinders a group's ability to carry about terrorist attacks. Case studies illustrate whether decapitation has an effect on the operational capacity of an organization by identifying whether the removal of key leaders changes the number and lethality of attacks. If certain organizations are more resilient than others, it is important to know when decapitation should be effective and when it could lead to counterproductive outcomes. Overall, these findings illustrate the need to develop a new model for evaluating the efficacy of leadership decapitation and for developing effective counterterrorism policies.  相似文献

Introduction     
SUMMARY

Previously homeless women (17) and men (12) were surveyed on their experience as a caregiver to physically challenged senior citizen clients (16 men, 13 women: age M= 64.7, SD = 16.8). Caregivers had training in service delivery and experience before the survey. More satisfaction than stress from providing care was reported by caregivers. Caregiving satisfaction was significantly positively related to global life satisfaction and a sense of personal vulnerability to being disabled. Caregiving stress was significantly negatively related to perceived knowledge of the disability. Overall, these previously homeless caregivers reported that providing care to the disabled was positive, and would be repeated and recommended to Others.  相似文献

Advances in information technologies over the last two decades have offered the promise of revolutionizing workplaces and other settings by expanding the capabilities of individuals working in various professions. Enabled by high-speed computing systems and marked by an intensification of command and control properties, new technologies have expanded, and in some cases intentionally surpassed, the scope of the senses. Technologies such as drones, surveillance cameras, and airport and border security systems promise the seemingly infinite catchment and infinitesimal account of human actions, while computer processing software provides real-time data on large-scale transactional processes occurring in monetary systems and security markets. Charting, tracking, and mapping functions open up new vistas for quantifying social behaviors and detecting misbehaviors, creating new frontiers for criminal justice, the military, and economic activity. The papers in this special issue reveal the processes guiding the rapid transformation and flexible adaptation of institutional structures, economic and financial systems, and threat surveillance and military/police mobilization in the near future.  相似文献

This paper examines views of the respondents regarding homeland security and traditional crime in the United States. Using questions from the 2007 Penn State Poll, a sample of 862 Pennsylvanians participated through a telephone interview. Participants were questioned about their concerns regarding the effectiveness of homeland security, their fear of crime (white-collar, property, violent and terrorist attacks). The results revealed that citizens were satisfied with the effectiveness of homeland security since the September 11, 2001, attacks. The results indicate that fear of crime is different for demographics, and we were able to show that those that thought homeland security had been effective increased the likelihood of fear of white-collar crime. We were also able to show demographic differences for national spending on crime. In addition, we were able to show that those who believed that homeland security was effective did not believe that national spending was at the proper level for property, violent, or white-collar crime. The implications of these results are discussed.  相似文献
