Drug-facilitated sexual assault using tetrahydrozoline

Drug-facilitated sexual assault (DFSA) has been defined as the use of a chemical agent to facilitate a sexual assault. We report two cases of the use of tetrahydrozoline for DFSA. We believe this is the first report with urinary quantification of tetrahydrozoline levels postassault. Blood and urine were obtained c. 20 h postexposure in two cases of reported DFSA. Tetrahydrozoline was not detected in blood but was identified in urine in both victims. After initial identification in the urine using the 2010 update to the AAFS mass spectrometry database library, tetrahydrozoline was quantified at 114 and 150 ng/mL, respectively, using GC/MS. Two unique clinical features reported in these cases were intermittent periods of consciousness and postexposure vomiting. Use of GC/MS was successful in identifying tetrahydrozoline in the 100 ng/mL range up to 20 h postexposure. For victims with late presentation, urine may be a better sample for evaluation for tetrahydrozoline.     

The Influence of Legal Reform on the Probability of Arrest in Domestic Violence Cases

Using domestic violence incidence and arrest data from Maryland (1991–1997), this research examines whether the proportion of incidents that result in arrest increased due to a legislative initiative implemented in 1994 and, if so, whether this change is uniform across different types of offenders (race and gender) and offense characteristics. Using interrupted time‐series analysis (ARIMA), we observe an increase in both the number of incidents reported to police and the percent of reported cases resulting in arrest. The legislative intervention has a significant positive impact on arrest likelihood above and beyond the increase over time for the state as a whole. While arrest probabilities increased across the board for males and females, African American and Whites, the ARIMA models do not suggest that the legislation differentially impacted arrest probabilities for these groups.     

法院在防治家庭暴力中的作用实证研究——以重庆市某区人民法院审理涉及家庭暴力案件情况为对象

通过实证调研,其结果显示家庭暴力的发生率仍然较高,并且当事人呈现出性别、年龄、职业等方面的特点。人民法院在涉家庭暴力案件的审理过程中,既有家庭暴力认定、举证责任分配、人身安全保护裁定送达、调解方法上的有益经验,也面临着防治家庭暴力立法及反家庭暴力联动机制不完善、人身安全保护裁定的局限性、取证难等一些困境。建议我国尽快制定一部统一的"家庭暴力防治法",在加强防治家庭暴力宣传的同时,明确规范各相关部门的职责与责任,加强各部门之间的联动协作。     

Collecting and Analyzing DNA Evidence from Fingernails: A Comparative Study,,

Forensic practitioners and crime laboratories regularly collect and analyze fingernail evidence; however, the best techniques for processing such evidence have not been established. In this study, numerous aspects of fingernail evidence processing—collection of exogenous cells, transportation, purification of DNA, and STR analysis—were analyzed using fingernails harboring applied blood or epithelial cells from scratchings. Autosomal STR mixtures resulted when fingernails were soaked or swabbed, while scrapings rarely generated mixtures but exhibited allelic dropout. Y‐STRs yielded single source profiles, with scrapings again showing dropout. A silica‐based kit extraction recovered significantly more exogenous DNA than did organic extraction, neither of which was affected by nail polish. Swabbing nails in succession resulted in some cross‐contamination from exogenous material, while transporting nails together did not, although there was loss of exogenous cells. Optimized nail processing produced complete Y‐STR profiles of male volunteers from female fingernails following scratchings.     

Hearing parties' voices in Coordinated Family Dispute Resolution (CFDR): An Australian pilot of a family mediation model designed for matters involving a history of domestic violence

This paper discusses the Coordinated Family Dispute Resolution (family mediation) process piloted in Australia in 2010–2012. This process was evaluated by the Australian Institute of Family Studies as being ‘at the cutting edge of family law practice’ because it involves the conscious application of mediation where there has been a history of family violence, in a clinically collaborative multidisciplinary and multi-agency setting. The Australian government's failure to invest resources in the ongoing funding of this model jeopardises the safety and efficacy of family dispute resolution practice in family violence contexts, and compromises the hearing of the voices of family violence victims and their children.     

U.S. child custody outcomes in cases involving parental alienation and abuse allegations: what do the data show?

ABSTRACT

Family court and abuse professionals have long been polarized over the use of parental alienation claims to discredit a mother alleging that the father has been abusive or is unsafe for the children. This paper reports the findings from an empirical study of ten years of U.S. cases involving abuse and alienation claims. The findings confirm that mothers’ claims of abuse, especially child physical or sexual abuse, increase their risk of losing custody, and that fathers’ cross-claims of alienation virtually double that risk. Alienation’s impact is gender-specific; fathers alleging mothers are abusive are not similarly undermined when mothers cross-claim alienation. In non-abuse cases, however, the data suggest that alienation has a more gender-neutral impact. These nuanced findings may help abuse and alienation professionals find some common ground.     

Separation of sperm and epithelial cells based on fluorescence-activated cell sorting

The detection and separation of spermatozoa is crucial in the forensic investigation of alleged sexual assault cases. Differential lysis and microscopy-based techniques are conventional methods for the isolation of spermatozoa, though are time-consuming and frequently fail with samples containing an unfavourable sperm/epithelial cell ratio. Successful separation by means of fluorescence-activated cell sorting (FACS) has previously been reported, yet little efforts have been dedicated towards the further improvement or routine implementation of this technique. With this ongoing research, a methodology is being developed to sort sperm from epithelial cells by combining the Sperm Hy-Liter™ staining kit and FACS. Sorted sperm cells are then subjected to a direct lysis and low volume PCR (LV-PCR) protocol. Preliminary results demonstrate the successful separation of both cell types at a sperm/epithelial cell ratio of up to 1:500. The direct lysis and LV-PCR protocol allows to produce full haploid profiles from single sperm cells and mostly full diploid profiles from 10 spermatozoa. These data suggest that the proposed methods are potentially viable for forensic casework, yet additional testing is required for validation purposes.     

地区竞争、选举政治与“一带一路”债务可持续性——剖析所谓“债务陷阱外交”论

从2017年开始,国际舆论较为频繁地使用"债务陷阱外交"描述中国"一带一路"倡议背后的战略目的。从经济角度衡量,中国给"一带一路"沿线国家的贷款条件并不苛刻,且在中国推出"一带一路"之前,大量中低收入国家的债务负担就已经出现明显增长趋势,并不存在"一带一路"引发系统性"债务陷阱"的问题。因此,"债务陷阱外交"论缺乏经济基础。进而可以发现,东道国及其所处的地区政治环境在"债务陷阱外交"论产生与传播的过程中扮演了重要角色。为此,本文构建了一个地区环境与国内政治选举相互作用的分析框架,通过比较案例研究分析了"债务陷阱外交"论在典型国家出现、传播与发挥影响的机制。"一带一路"项目往往与东道国执政者"政治捆绑",国内权力更迭导致的国家发展战略变动,为该国政府改变自身对"一带一路"的政策选择创造了空间,其所处的地区政治环境也显著影响政策变化的幅度。中国在推进"一带一路"建设时,既要与东道国进行双边互动,充分重视东道国国内不同力量的博弈,也要注意到沿线国家所处地区政治环境对该国能否持续参与"一带一路"构成制约。我们需要以一种更加多维的视角进行思考,超越传统的紧盯美国的对外政策模式,为"一带一路"的顺利实施营造更加良好的政治环境。     

There’s an app for that: Modernizing domestic violence support through the creation of new technologies,tools, and services

With domestic violence (DV) at an all-time high, police departments are drastically underutilizing technology to combat DV. Currently, New York police departments complete a “Domestic Incident Report” at the scene of domestic incidents but fail to adequately facilitate support services. New York State should mandate a services component into police DV protocols, specifically by commissioning: (1) an application linked to DV organizations presented at the scene of domestic incidents; and (2) a gateway application to refer victims to the correct services. Such tools would allow for the rendering of more efficient support to DV victims in times of immediate crisis.     

Japan's foreign aid: old and new contests

Abstract

Domestic and international contests explain the transformation of Japan's foreign aid programme begun in the early 1950s. Through contests between domestic players, Japan has streamlined its aid processes by introducing institutional innovations, accommodating new actors in aid policy and delivery, and responding more sensitively to public opinion and independent advice. At the international level, contests have come from the Development Assistance Committee/Organization of Economic Cooperation and Development (DAC/OECD), the USA, and China. Through these contests, Japan has emerged as a more rounded aid donor. Its new aid model blends Western principles with concepts of ‘self-help’, favouring large infrastructure projects that serve both Japan's and recipient countries’ interests.
