High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.  相似文献

The role of civil society organizations (CSOs) as a watchdog in the implementation process is widely acknowledged. However, little is known about what determines their capacity to monitor EU policy implementation and how it differs across member states. This article accounts for social capital as well as human and financial capital to determine the monitoring capacity of CSOs. To capture sources of social capital, a network analysis is applied in a comparative case article on the monitoring networks of national platforms of the European Women’s Lobby across eight EU member states. The analysis reveals that CSOs in western member states are rich in human, financial and social capital, while CSOs in CEE member states compensate for this lack of resources by linking up with the Commission.  相似文献

社会保障权责配置有政府与市场和政府间之横纵两个层级。滞后的社会保障法制导致权责横纵配置的失衡-政府与市场之间配置的偏倚,政府之间配置的粗疏,这严重制约该制度功效的彰显。横向配置矫正的关键在于寻求政府责任的确定性与实现方式的多样性之间的平衡,并在发挥政府基础性作用时,倡导个人责任的回归、市场机制的引进及民间力量的渗透。纵向关系的细化要求以宪法层面原则性规定与法律层面具体性条款相结合的方式进一步规范各级政府的事权及其支出责任;从责任分担上做出更具操作性的制度安排,完善政府间社会保障支出责任分担法律机制。  相似文献

Using the Princeton nuptiality index Im, we analyzed historical developments in the proportion of married women of reproductive age in Spain. We show the internal diversity in nuptiality patterns and offer an explanatory statistical model based on panel data analysis to identify the main variables influencing these changes over more than a century (1887–1991). We found that Spain has been the developed country with the greatest contrasts in its provincial nuptiality patterns (measured by Im), although this diversity has lessened over the course of time. We also found that some socioeconomic variables (the gross domestic product per capita and the percentage of population living in cities) do not have a linear relationship with female nuptiality but rather have a U shape or an inverted U shape. This may partly account for some of the controversy that has raged on this topic over the past few decades on an international level.  相似文献

在产业发展过程中,政府在经济发展的不同阶段都会制定与产业相关的各种政策鼓励重点产业的发展。政府选择重点产业动因是重点产业能支撑经济快速发展,能引导产业结构的调整,能发挥区域比较优势,能代表产业发展方向。结合国家深入实施西部大开发战略背景,选取7个指标基于SPSS对重点产业发展的比较优势进行实证分析。以贵阳市为例,指出重点产业选择的基本方向并提出相应的政策建议。  相似文献

沉默权制度的发展、利弊与限制   总被引:1,自引:0,他引:1  
沉默权制度作为诸多国家在刑事诉讼中保障犯罪嫌疑人、被告人人权的一项重要制度,有必要对其历史发展、利弊及现今限制等问题予以了解,这对我国正在酝酿的刑事诉讼法的整体修改以及相关问题的废、改、立具有重要意义。  相似文献

Recent studies on European Union (EU) Enlargement have emphasised the importance of usages of ‘Europe’ by domestic actors as a necessary condition for the EU to have an impact on domestic politics. We study the usages of Europe in the critical case of Turkey’s nuclear energy policy. We analyse the narratives and actions of domestic actors in Turkey to identify if they use ‘Europe’ (the EU and the idea of Europe). We reach the counter-intuitive finding of usages by both state and non-state actors, which illustrates that usages of Europe can persist despite enlargement stasis in candidate states.  相似文献

While the January 2015 Paris terrorist attacks presented a crucial opportunity for far-right mobilisation, the focus on liberal democratic values and Charlie Hebdo’s non-conformist progressive profile presented challenges for right-wing discourse. Taking Italy as a paradigmatic case of public controversies on cultural and religious affairs, this article examines the opportunities and constraints generated by multicultural crises for far-right framing choices. A qualitative frame analysis analyses the discourse of three types of far-right actors. While the populist radical right, extreme right, and ultra-religious right groups disagree on crucial criteria for outgroup exclusion, they collectively employed the Charlie Hebdo controversy to redefine their exclusionary discourse on liberal grounds with the goal of gaining legitimacy in the mainstream public sphere.  相似文献
