A NEW LOOK AT AN OLD ISSUE:

In 1997, the Office of Child Support Enforcement initiated the State Child Access and Visitation (AV) Grant Program, which involves annual awards of $10 million to states to promote the development of programs to alleviate access problems. Telephone interviews with 970 parents who used mediation, parent education, and supervised visitation programs funded by AV grants in nine states revealed that the programs are reaching diverse groups of parents including many low-income, non-White, and unmarried parents who receive no other type of access assistance. The programs also appear to be achieving the major objectives posited for them by the federal government. One-third to one-half of noncustodial parents in every program type reported that parent–child contact increased following program participation, with supervised visitation users who typically had the lowest levels of parent–child contact reporting a significant increase in the number of days of contact. A review of child support records for 173 program users in three states revealed that child support payments increased among participants following program participation, especially for never-married parents who paid a significantly higher proportion of what they owed. These findings are similar to results reported in a five-state study of mediation programs funded by AV grants that was conducted by the Office of the Inspector General. However, both studies have some serious limitations, including low response rates and the absence of a nontreatment comparison group.     

SUPERVISED VISITATION: A CALL FOR A SECOND GENERATION OF RESEARCH

With the divorce rate rising and related child visitation disputes becoming an increasingly difficult issue before the courts, supervised visitation programs have proliferated over the last decade. The literature demonstrates that ongoing contact between children and both parents following separation and/or divorce is important for children's socio‐emotional adjustment and positive child/parent relations. However, there is a paucity of literature demonstrating a relationship between supervised visitation programs and child/parent relationship outcomes. Based on the lack of outcome research the authors argue for a second generation of research regarding intended and unintended consequences of supervised visitation. This article reviews and synthesizes the current literature, highlighting strengths, limitations, significant findings and proposes a critical need for evidence‐based research.     

眼钝挫伤与脑肿瘤伤病关系法医学鉴定1例

本文通过对一例被鉴定人眼部钝挫伤后出现视力下降,同时发现其患有脑星形细胞瘤的案例,讨论了如何准确地判定上述伤病关系,如何对该眼部钝挫伤的损伤程度作出公正、科学的法医学鉴定,并分析了伤病关系理论在法医学鉴定中的重要作用。     

K~+/Na~+比值与损伤时间的关系

本文使用原子吸收光谱法测定12只大鼠36个烧伤局部肌肉标本的 K~+/Na~+值,检测结果:生前60、 30、 15min 以及死后20min 肌肉标本的 K~+/Na~+值比对照组分别下降:69～94％(平均86％)、56～89％(平均77％)、47～82％(平均71％)、4～38％(平均27％),此结果经统计学处理,表明生前伤与死后伤的 K~+/Na~+比值的下降率有明显差异。同时发现生前损伤的各实验组随存活时间的延长,K~+/Na 比值的下降率有增加的倾向。笔者认为,此方法是烧伤时间推断的一种简便,可靠的方法,对法医学实践有一定实用价值。     

小鼠皮肤切创愈合过程中caspase-3的表达及其活性

目的探讨皮肤切创愈合过程caspase-3的表达、激活情况及其活性的变化规律。方法建立小鼠皮肤切创模型后,应用比色法、Western blotting技术对小鼠皮肤切创愈合过程中不同时间段caspase-3的表达、激活情况及其活性进行研究。结果伤后不同时间的caspase-3活性倍增值、caspase-3酶原表达呈现时间规律性变化,并可见caspase-3的激活片段。结论caspase-3可能在皮肤损伤愈合过程中细胞的凋亡中发挥作用,caspase-3可以成为用于皮肤损伤时间推断的指标。     

农村留守妇女的社会支持网构成研究——基于16省66县2414名留守妇女的调查

社会支持网是正式的社会保障体系的一种补充。在工业化、城市化的浪潮中,大量青壮年农民进城务工,传统的"男耕女织"演变为"男工女耕",农村留守妇女成为新农村建设的主力军,不得不重构自己的社会支持网。然而,目前国内很少有关于农村留守妇女的个体社会支持网构成的实证研究。本文通过对16个省份2414名留守妇女的抽样问卷调查资料系统考察留守妇女的社会支持网的构成。调查发现:丈夫仍然是"缺席"的户主,构成留守妇女情感支持网、财务支持网的重心;"娘家人"在留守妇女社会支持网中的重要性超过了"公婆",尤其在情感支持和财务支持方面;邻居、朋友都是留守妇女日常交往的主要对象,邻居还对留守妇女的生产活动提供帮扶,而朋友则是留守妇女情感倾诉的主要对象之一。亲属倾向于情感支持、财务支持,而非亲属倾向于交往支持。     

Coming to Grips with Realism

Retrieving Realism renders the joint philosophical goals of Hubert Dreyfus and Charles Taylor into what is probably their final and most concise form. It has two main objectives: first, it aims to deconstruct the mediationalism that undergirds Western philosophy, and second, it endorses contact theory, or embodied/embedded coping, as an alternative. In this essay, I present the book’s most salient themes and reveal areas that are ripe for further philosophical consideration. I also direct the reader to the work’s genuine ontological challenge: how to come to grips with contact theory beyond the borders of epistemology.     

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.
