Researchers have shown that mood and sense of control over one's life are significantly affected by testimony and other forms of disclosure and that learning to control breathing has positive effects on mood and anxiety. This preliminary experiment tests whether African American and European American abused women who give testimony about their experiences of intimate partner violence and learn how to use yogic breathing techniques have reduced feelings of depression. Results indicate that learning yogic breathing techniques alone and combined with giving testimony significantly reduces feelings of depression. Recasting women as authorities on domestic violence and teaching them how to calm their minds by focusing on yogic breathing may be simple and effective ways to help women take control over their bodies and lives. 相似文献

Abstract: The influence of clothing and wrapping on carcass decomposition and arthropod succession was investigated to provide data to enable estimated postmortem interval in homicide investigations. Six pig carcasses, Sus scrofa, were divided into three sample groups, each with a clothed carcass wrapped and a carcass wrapped with no clothes. Two more carcasses, one with no clothes or wrapping, the other with clothes and no wrapping were used as controls. The clothed or wrapped carcasses had larger visible maggot masses, which moved more freely and these carcasses took longer to dry out. The blow fly maggot masses were dominated by Chrysomya marginalis and Chrysomya albiceps. Oviposition occurred simultaneously on all carcasses. High temperatures in one case caused significant maggot mortality. The Coleoptera community was dominated by Silphidae, Thanathopilus micans larvae, Dermestidae, Dermestes maculatus adults and larvae, and Cleridae, Necrobia rufipes. 相似文献

This paper describes some of the issues around which cooperation among police agencies in the South African region have been
coalescing. Cooperative engagements have resulted in a degree of harmonisation of policy and standardisation of police training.
Within the region too a rhetorical commitment to common values and standards associated with democratic policing is forthcoming.
Overall the processes underway are shaped by regional dynamics of a broader socio-political and specific police organisational
nature. Structural underdevelopment, the weakness of institutions such as the police and contrarian politics more widely provide
the context within which cooperation has evolved. By drawing on documentary analysis and interviews with practitioners in
the field, the substantive areas around which cooperation is taking place are outlined. In this account particular reference
is made to the role of a regional structure (the Southern African Regional Police Chiefs Coordination Committee) and the national
police agency (the South African Police Service) of South Africa, in the evolving business of cooperation in the Southern
African region.
Research for this paper was made possible through funding received from the Open Society Foundation (SA).

Abstract: This paper presents how jewelry modeling waxes are used in the preparation of tool mark standards from exemplar tools. We have previously found that jewelry modeling waxes are ideal for preparing test tool marks from exemplar tools. In this study, simple methods and techniques are offered for the replication of accurate, highly detailed tool mark standards with jewelry modeling waxes. The techniques described here demonstrate the conditioning and proper use of jewelry modeling wax in the production of tool mark standards. The application of each test tool's working surface to a piece of the appropriate wax in a manner consistent with the tool's design is clearly illustrated. The resulting tool mark standards are exact, highly detailed, 1:1, negative impressions of the exemplar tool's working surface. These wax models have a long shelf life and are suitable for use in microscopic examination comparison of questioned and known tool marks. 相似文献

This article presents and tests a knowledge and technology transfer framework in a quadruple helix environment, from an actor perspective. The Canadian forest products industry provides a unique opportunity for data collection through case studies as it is an industry built on a triple bottom line, which is managed for sustainable progress. By confronting the new framework to 31 professionals, we highlight the role and challenges faced by each helix. Several factors such as culture, time horizon management and the adaption of theory to practice appear to be determinant to improve technology transfer. We see in our work an important contribution to the generalization of knowledge and technology transfer processes in a quadruple helix environment. 相似文献

The current study examines the relationship between military service and criminal behavior of veterans, both combat and non-combat, compared to non-veterans using a nationally representative sample of inmates. Specifically, this study examines the relationship between veteran status and crime type among inmates in state and federal institutions. While the relationship between military service and criminal behavior of veterans has received considerable attention, many have failed to differentiate between veterans who have seen combat versus those who have not. Therefore, a subsample of veterans who experienced combat during their military service is examined to better inform our understanding how combat experience might influence this relationship. Multiple counterfactual methods, including propensity score matching, were used on data from the Survey of Inmates in State and Federal Correctional Facilities, 2004. Some significant differences exist in the types of offenses committed based on veteran status and combat experience, but in some cases contrary to expectations. Veterans were more likely to have committed a violent offense, but less likely to have committed drug offenses; whereas, combat veterans were more likely to commit a drug offense and less likely to commit a violent offense than non-combat veterans. Policy implications and recommendations for future research are explored. 相似文献

DNA traces found at crime scenes and DNA records held in databases have already helped the police to solve numerous investigations into specific crimes. The police clearly benefit from the use of forensic science at an operational (i.e. case) level. This paper focuses on the use of forensic DNA at a strategic level: its use in the study of patterns of criminal behaviour. The usual sources of information for this type of research are recorded crime data, self-report studies and victimization surveys. However, as our review will show, these data sources cannot provide a complete picture of crime. We therefore propose an alternative approach to criminological research that takes into account DNA databases and has the potential to augment current methods and extend the existing knowledge beyond known offenders. The use of DNA databases has an important advantage for criminological research: it is possible to link offences committed by the same individual, whether the offender’s identity is known or not. By making a one-on-one comparison of police data with the corresponding DNA data, not only can co-offenders be studied, but a larger network of offenders connected to each other can also be analysed, even if their identity is unknown to the police. 相似文献

The International Energy Agency after 35 years: Reform needs and institutional adaptability 总被引:1,自引:0,他引:1
Despite the mounting scholarly interest in processes of institutional change in international organizations, still very little
is known about how and when such evolutionary dynamics occur. This article hopes to contribute to this young, yet growing
body of literature by process-tracing the changes that have occurred in the institutional setup of the International Energy
Agency (IEA). Founded during the first oil crisis of 1973–74, the IEA has had to deal with major environmental changes over
its lifetime. In response, the agency has diversified away from its original raison d’être, namely managing an emergency oil sharing mechanism, to become a more proactive policy adviser guiding its member governments
toward sustainable energy economies. The article seeks to explain the observed patterns of change and inertia, using a theoretic
paradigm that builds on theories of “new institutionalism.” The paper argues that the agency’s institutional flexibility can
only be fully explained by taking into account a combination of factors: (1) the member states’ choices, in particular the
impulses of the G8-members of the IEA; (2) path dependency, especially the institutional link with the Organization for Economic
Cooperation and Development (OECD); and (3) agency by the secretariat and the executive bureau of the IEA. 相似文献

School Belonging and School Misconduct: The Differing Role of Teacher and Peer Attachment 总被引:1,自引:0,他引:1
The schools-as-communities perspective provides a popular explanation for school-disruptive behavior, stating that interpersonal
bonding at school and feelings of school belonging prevent misconduct. In this article, we build on this perspective in three
ways. First, we test whether the preventive influence of school belonging acts at the individual or school level. Secondly,
we test whether a distinction should be made between the different actors with whom students bond at school, by assessing
whether perceived teacher support, school belonging, and peer attachment relate differently to school misconduct. Lastly,
the present study investigates whether the associations of bonding with teachers, peers and the school with school misconduct
differ by socio-ethnic school context. Multilevel analyses were performed on data from the Flemish Educational Assessment.
The sample consisted of 11,872 students (51.4% female) in 85 schools, most of whom were natives (88.8%), with immigrants (11.2%)
mostly having Turkish or Moroccan backgrounds (both about 30% of immigrants in the sample), and others Southern-European (16%),
Eastern-European (8%), North-African (5%), or other (17%) backgrounds. Results showed that the students’ individual feelings
of bonding with peers, teachers and school associate with school misconduct, rather than the overall school cohesion. Results
further showed that, while higher perceived teacher support and school belonging related to less school misconduct, higher
peer attachment was associated with higher rates of school misconduct. No differences were found by socio-ethnic context.
Implications are discussed. 相似文献

This article extends the study of regulatory enforcement on three levels. First, it separates enforcement style elements during inspections and sanction decision‐making work, creating a more realistic measurement. Second, it focuses on how these elements function in a context where it is hard in practice to achieve deterrence. Third, it assesses how agents view the effectiveness of combinations of style elements in such a context. To do so, it uses survey and interview data with street‐level environmental officials in Guangzhou, China. It finds that the agents studied practise enforcement that goes beyond deterrence and uses education and persuasion more effectively. It finds that the behavioural assumptions of these agents are to a large extent in line with the available regulatory literature, although agents are very unlikely to have consulted such studies. Therefore, the article concludes that law enforcement agents can develop nuanced and appropriate behavioural intuitions through their everyday work experiences. 相似文献
