Several studies have indicated that there are potential environmental sources of particles resembling inorganic primer found in gunshot residues (GSR); as a consequence examiners are reluctant to unambiguously assign the origin of inorganic particles. If organic gunshot residues (OGSR) were found in combination with inorganic particles, the possibility of environmental sources could be potentially eliminated, thereby significantly enhancing the strength of the evidence. Methods have been previously described whereby GSR specimens can be analysed for the presence of OGSR or inorganic GRS (IGSR). However, no methods have been reported that allow the analysis of both OGSR and IGSR on the same specimen. Described in this article is a direct method using desorption electrospray ionisation-mass spectrometry (DESI-MS) for the detection of methyl centralite (MC), ethyl centralite (EC) and diphenylamine (DPA) on adhesive tape GSR stubs typically used for scanning electron microscopy-energy-dispersive X-ray (SEM-EDX) analysis. The optimisation of numerous parameters was conducted using an experimental design. The results indicate that direct analysis of these organic components of GSR is possible although some limitations were also identified. This initial investigation has also indicated that subjecting stubs to DESI analysis does not interfere with subsequent SEM-EDX analysis of primer residues; therefore the technique described herein allows a comprehensive examination of GSR that would be highly probative in the event that both OGSR and IGSR are detected in the same specimen. 相似文献

Analysis of psychometric data from a sample of 413 child molesters who had completed a U.K. probation-based sex offender treatment program was carried out to assess (a) the effectiveness of therapy in the short term and (b) the longer term implications of treatment in relation to sexual recidivism. It was found that 12% (51 offenders) of the sample had recidivated within 2 to 4 years. Of these recidivists, 86% (44 offenders) had been reconvicted for a sexually related offense. One hundred thirty-five offenders (33%) demonstrated a treated profile (i.e., demonstrated no offense-specific problems and few, or no, socioaffective problems at the posttreatment stage). This group was compared with a sample of offenders deemed as not responding to treatment, matched by their levels of pretreatment risk/need. It was found that a significantly smaller proportion (n = 12, 9%) of treatment responders had recidivated, compared to the treatment nonresponders (n = 20, 15%), indicating a 40% reduction in recidivism in those who had responded to treatment (effect size = .18). Matching length of treatment to the offenders' level of pretreatment risk/need (i.e., higher risk/treatment-need offenders typically undertook longer treatment) reduced the rate of recidivism among this group to the level of recidivism observed among the lower risk/need offenders. 相似文献

Objectives
Investigate the degree and nature of influence that researchers have in police crime prevention programs and whether a high degree of influence is associated with biased reporting of results.Methods
Meta-analytic inquiry of experimental and quasi-experimental studies (n?=?42), drawn from four Campbell Collaboration systematic reviews of leading police crime prevention strategies: problem-oriented policing, ??hot spots?? policing, ??pulling levers?? policing, and street-level drug enforcement.Results
Larger program effects are not associated with studies with higher involvement on the part of the evaluator (e.g., assisting in strategy design, monitoring implementation, overcoming implementation problems).Conclusions
This study does not find support for the cynical view, which holds that researchers have a personal stake in the program or are pressured to report positive results. Importantly, the evaluator??s involvement in the implementation of the program may be a necessary condition of successfully executed police experiments in complex field settings. 相似文献205.

In order to help the parties in mediation address their interests, concerns, and responses to the conflict, the mediator must monitor and manage his or her own inner thoughts, emotions, and feelings throughout the process lest they negatively influence the outcomes of the mediation. Peer consultation offers one approach that can be used effectively to support the mediator's inquiry into practice dilemmas and invite self-knowing that benefits the mediator as well as the parties in the mediation. The effectiveness of a group consultation process, however, depends on the development of "a holding environment" that can provide a safe and confidential space within which such an inquiry can occur. The mediation process is improved when the mediator is able to sustain relational and emotional tension within herself and between the parties long enough for new understandings and actions to develop. 相似文献

This article examines women’s rights to property in marriage, upon divorce, and upon the death of a spouse in Uganda, highlighting
the problematic aspects in both the state-made (statutory) and non-state-made (customary and religious) laws. It argues that,
with the exception of the 1995 Constitution, the subordinate laws that regulate the distribution, management, and ownership
of property during marriage, upon divorce, and death of a spouse are discriminatory of women. It is shown that even where
the relevant statutory laws are protective of women’s rights to property, their implementation is hindered by customary law
practices, socialization, and the generally weak economic capacity of many women in the country. The article delves into the
even weaker position of women’s rights to matrimonial property at customary and religious laws. In many homes, wives provide
labor to support their husbands without having a stake in the use or monetary benefit from it. Under Islamic law regulating
intestate succession to property, the entitlements for widows fall short of the constitutional standards on equality and non-discrimination.
Polygyny is widely practiced by Muslims implying that the widows share the one eighth whenever there are children or one fourth
in cases when there are no children. Radical reforms such as adopting an immediate community property regime instead of the
present separate property regime are inevitable if women’s rights to property are to advance. 相似文献
