Analyzing Forensic Evidence Based on Density with Magnetic Levitation

This paper describes a method for determining the density of contact trace objects with magnetic levitation (MagLev). MagLev measurements accurately determine the density (±0.0002 g/cm³) of a diamagnetic object and are compatible with objects that are nonuniform in shape and size. The MagLev device (composed of two permanent magnets with like poles facing) and the method described provide a means of accurately determining the density of trace objects. This method is inexpensive, rapid, and verifiable and provides numerical values—independent of the specific apparatus or analyst—that correspond to the absolute density of the sample that may be entered into a searchable database. We discuss the feasibility of MagLev as a possible means of characterizing forensic‐related evidence and demonstrate the ability of MagLev to (i) determine the density of samples of glitter and gunpowder, (ii) separate glitter particles of different densities, and (iii) determine the density of a glitter sample that was removed from a complex sample matrix.     

Neighbourhood Ethnic Diversity and Orientations Toward Muslims in Britain: The Role of Intergroup Contact

A persistent theme in the British and international debates about immigration and diversity is the controversial claim that living in diverse areas has negative consequences for intergroup attitudes and community relations. In the present paper we test this claim by investigating the impact of neighbourhood diversity and self‐reported intergroup contact on orientations (outgroup attitudes and social distance) toward one religious outgroup: Muslims. Respondents were both White British majority (N=867) and non‐Muslim ethnic minority (N=567) residents of neighbourhoods in England which varied in their proportion of ethnic minority residents. We tested both direct and indirect (via intergroup contact) effects of diversity on outgroup orientations toward Muslims. Results show that individuals living in more ethnically diverse areas—regardless of whether they are White British members of the majority or non‐Muslim members of ethnic minorities—have more positive contact with Muslims, with positive consequences for intergroup relations with Muslims.     

鞋内底不同部位接触DNA提取初探

目的探讨鞋内底不同部位接触DNA提取检出率。方法取100名20-30岁的志愿者,将其穿用过的运动鞋和皮鞋鞋垫设置成不同穿用时间组、不同材料鞋垫组、穿用后不同放置时间组,根据脚的形态学及运动力学特点,将鞋垫分成8个区域进行脱落细胞提取,并进行DNA进行检验。结果鞋垫上8个不同区域提取到的脱落细胞DNA分型检验效果不同。足弓外侧区（足引折弓除外）的接触DNA检出率最高;足弓内侧、第1趾骨区、第1跖骨区及足跟区次之;第2～5趾骨区、第2～3跖骨区、第4～5跖骨区不容易成功提取到接触DNA。结论鞋内底接触DNA检出率与接触时间、放置时间、鞋垫材质均相关,分区提取检验DNA更有针对性。     

Grandparent contact: another presumption?

ABSTRACT

This article reviews the debate about the enhancement of grandparents’ legal status in relation to their grandchildren. In particular, it observes that calls for a legal presumption in favour of grandparent contact with their grandchildren when family relationships break down were emboldened by the enactment in s1(2A) of the Children Act 1989 of a presumption that involvement of both parents in their children’s lives furthers children’s welfare. Proponents of grandparent rights argued that there should be a similar statutory presumption in favour of grandparent involvement. It is also argued that courts should strictly enforce child arrangement orders that give grandparents time with grandchildren. The article examines the welfare case for such involvement and concludes that there is no unequivocal evidence to support it. It also considers the effect of the presumption in s1(2A). The article concludes that to enact a similar presumption in favour of grandparents, to apply a de facto presumption, to enforce orders strictly and even to remove the leave requirement that currently exists, could prejudice the interests of mothers as well as children.

Inter-ethnic (In)tolerance between Turks and Kurds: Implications for Turkish Democratisation

Using public opinion survey data, this study investigates the determinants of inter-ethnic (in)tolerance among Turks and Kurds in Turkey. Our empirical analyses show that, compared with Turks, Kurds have a relatively higher level of tolerance towards the ethnic out-group. Our findings also suggest that different dynamics and factors mould Turks’ and Kurds’ tolerance towards ethnic out-group members. Religiosity, (ethno)nationalist orientations, inter-ethnic contact, threat perception and economic factors are the most consistent variables shaping Turks’ tolerance towards Kurds. In contrast, religion-related factors and inter-ethnic social contact do not have a statistically significant effect on Kurds’ tolerance towards Turks. (Ethno)nationalist orientations, however, appear to reduce Kurds’ tolerance.     

交往:道德教育的必然走向

当前,工具性道德教育仍是道德教育的主导形式,其存在严重的功利化、政治化、知识化、制度化倾向,这造成道德教育有效性的缺失。因而,我们必须探求道德教育的有效途径,道德教育必须回归原初交往本质,从工具性道德教育走向交往性道德教育。交往是道德教育的必然走向。     

Definitions and terminology regarding child alignments,estrangement, and alienation: A survey of custody evaluators

Parental alienation (PA) is a highly consequential family dynamic that causes harm to children and parents. While many mental health and legal professionals agree that PA is common and potentially very harmful to children, there is still the appearance that there is controversy and discord in the field. The purpose of this study was to test the extent of consensus in the field regarding the basic tenets of PA theory. Specifically, 11 key terms related to PA were identified through expert input and preliminary field-testing. An on-line survey was created specifically for the study to assess level of agreement with these key terms among custody evaluators. This profession was selected because of their high degree of training and experience with a variety of family conflict situations; 119 child custody evaluators selected as members of a professional custody evaluator listing (88% response rate) rated their endorsement of these 11 key definitions with response options including: strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree. Results revealed that roughly 80% of respondents agreed or strongly agreed with each of the 11 definitions. These results demonstrate a high degree of consensus and should guide future trainings of legal and mental health professionals to ensure a common language and understanding of this phenomenon.     

Assessing the Impact of the Juvenile Detention Alternatives Initiative (JDAI): Predictors of Secure Detention and Length of Stay Before and After JDAI

The Annie E. Casey Foundation’s Juvenile Detention Alternatives Initiative (JDAI) seeks to reduce the reliance on pre-dispositional detention. While anecdotal evidence indicates that the program has enjoyed some success in reducing detention populations, no controlled study has assessed the efficacy of the program. The current study investigated the impact of JDAI following its adoption in one Virginia juvenile court. Specifically, using data on all juveniles referred to intake over a seven-year period, the research analyzed predictors of detention and length of stay before and after JDAI. Results indicate that after the implementation of JDAI, greater emphasis was placed on legal factors including offense seriousness and prior record, though the increased emphasis was greater for non-whites than for white youth. Additionally, results suggest that after JDAI’s adoption, older non-white youth were more likely to receive secure detention while non-white females received some degree of leniency compared to non-white males.
