不同环境条件下大鼠死后皮肤生物力学特性改变

目的死亡时间的推测是法医病理学研究的重点和难点。皮肤具有一定生物力学特性,是机体死后分解破坏发生较迟的部分。本研究观察不同环境条件下死后大鼠皮肤生物力学特性的改变,探索其与死亡时间的关系。方法系统测试雌性SD大鼠在不同环境条件下（A组较高环境温度,B组较低环境温度）的死后皮肤生物力学特性。结果 A组大鼠皮肤死后张应力、延伸率在死后1d内先降低后升高,1d～6d逐渐降低,6d～7d略呈上升趋势;B组大鼠皮肤死后张应力在死后2d内先降低后升高,2d～16d逐渐降低,16d～20d略上升。结论 A组的张应力、延伸率和B组的张应力、应变能密度均表现出与死亡时间较好的相关性,是较好的推测死亡时间的生物力学参数。     

Participatory visual research with subsistence farmers in Papua New Guinea

This article discusses the trial of visual research methods in a socio-economic research and development project with women subsistence farmers and their families in two regions of Papua New Guinea (PNG). It reports on the benefits and challenges of three visual research methods (drawing, participatory photography, and picture elicitation) to explore the agricultural practice of women subsistence farmers and their families. The paper discusses the potential of these methods for enhancing community engagement, reducing the power imbalance between researchers and participants, and promoting dialogue and reflection to better understand the needs and practices of subsistence farmers.     

Empowering farmers? Collaborative research at Sokoine University of Agriculture,Tanzania

This article presents experiences with collaborative and on-farm research based on the implementation of a four-year Programme for Agricultural and Natural Resources Transformation for Improved Livelihoods (PANTIL) at Sokoine University of Agriculture (SUA) in Morogoro, Tanzania. It outlines the basic elements in the implementation of a programme aimed to be demand-based, and discusses the challenges encountered in combining collaborative research with the empowerment of farmers. Finally, the article draws out some lessons with implications for the future organisation of collaborative and on-farm agricultural research.     

Twenty reasons why local knowledge will remain relevant to development

Local knowledge has continued to gain popularity among development practitioners in the last four decades. However, the future of local knowledge seems hazy to some academics and researchers, perhaps due to the methodological challenges in operationalising local knowledge in development research. Rather than appropriate its full potential for sustainable (global) progress, renditions on the relevance of local knowledge in development research agenda have largely become rhetoric. Nonetheless, this viewpoint outlines 20 pertinent reasons in support of the relevance of local knowledge and why it has a future in development theory and practice.     

利用扫描电镜/能谱仪和X-射线衍射仪鉴别假“冰毒”

冰毒为纯白或淡黄色结晶体,为利益所驱,很多制贩毒者利用其它外观相似的晶体充当替代品或者掺杂剂,在常规检测时,用气/质联用仪无法检验其成分。本文利用扫描电镜/能谱仪和X-射线衍射仪对外观酷似"冰毒"的晶状物成分进行检测,先利用扫描电镜/能谱仪测定未知物主要元素,再利用X-射线衍射仪测定其晶体结构和成分。两者有效结合成功地鉴别假"冰毒"物质的成分。     

Parenting Plans for Special Needs Children: Applying a Risk‐Assessment Model

Family courts are seeing an increasing number of separating or divorced families who have a special needs child. These cases present complex challenges for family law professionals charged with crafting parenting plans based on best interests standards. For many of these children, the typical developmentally based custodial arrangements may not be suitable, given the child's specific symptoms and treatment needs. We present a model for understanding how the general and specific needs of these children, as well as the demands on parents, can be assessed and understood in the context of divorce. This includes an analysis of risk and protective factors that inform timeshare and custodial recommendations and determinations. The risk assessment model is then applied to three of the most commonly occurring childhood neurodevelopmental and psychiatric disorders likely to be encountered in family court, namely, attention deficit/hyperactivity disorder, depressive disorders, and autistic spectrum disorders.

Key Points for the Family Court Community
• There has been a dramatic rise in the population of children with neurodevelopmental, psychiatric, and medical syndromes whose parents are disputing custody in the family courts.
• Family law professionals of all disciplines should develop a fundamental knowledge base about the most commonly seen special needs children in family court, such as those with neurodevelopmental conditions like autistic spectrum disorder, attention deficit/hyperactivity disorder, and severe depressive disorders (especially with teenagers), which may involve suicidal or self‐harming behaviors.
• Commonly recommended parenting plans may be inappropriate for many special needs children, as some function significantly below their chronological age and pose extreme behavioral challenges.
• A systematic analysis of risk and protective factors should inform timeshare arrangements and determinations with this varied population, including the safety of the child and severity of the disorder, parental commitment and availability to pursue medical, educational, and therapeutic services, the parental attunement and insightful about the problem, and the differential parenting skills of each parent.

     

The Coalition and the Politics of the English Question

For much of the 2010–15 Parliament the English Question was not a conspicuous feature of political debate in the UK. However, the issue of English votes for English laws (EvfEl) was thrust to centre stage by Prime Minister David Cameron in the aftermath of the Scottish independence referendum, when he announced that fulfilment of the promise of further devolution to Scotland must be accompanied by an answer to the West Lothian Question at Westminster. This article analyses these events and explores their possible consequences. It argues that a reform of parliamentary procedures along the lines outlined in the report of the McKay Commission looks increasingly likely, but that this will not mark a resolution of the broader English Question, and the future of the Union remains in doubt.     

Public support for European defence: Does strategic culture matter?

This article identifies previously ignored determinants of public support for the European Union's security and defence ambitions. In contrast to public opinion vis‐à‐vis the EU in general, the literature on attitudes towards a putative European army or the existing Common Security and Defence Policy (CSDP) suggests that the explanatory power of sociodemographic and economic variables is weak, and focuses instead on national identity as the main determinant of one's support. This article explores the possible impact of strategic culture, and argues that preferences vis‐à‐vis the EU's security and defence ambitions are formed in part through pre‐existing social representations of security. To test this proposition, ‘national’ strategic cultures are disaggregated and a typology is produced that contains four strategic postures: pacifism, traditionalism, humanitarianism and globalism. Applying regression analysis on individual‐level Eurobarometer survey data, it is found that strategic postures help explain both the general level of support for CSDP and support for specific Petersberg tasks.
