Reducing complexity in Qualitative Comparative Analysis (QCA): Remote and proximate factors and the consolidation of democracy

Abstract.  Comparative methods based on set theoretic relationships such as 'fuzzy set Qualitative Comparative Analysis' (fs/QCA) represent a useful tool for dealing with complex causal hypotheses in terms of necessary and sufficient conditions under the constraint of a medium-sized number of cases. However, real-world research situations might make the application of fs/QCA difficult in two respects – namely, the complexity of the results and the phenomenon of limited diversity. We suggest a two-step approach as one possibility to mitigate these problems. After introducing the difference between remote and proximate factors, the application of a two-step fs/QCA approach is demonstrated analyzing the causes of the consolidation of democracy. We find that different paths lead to consolidation, but all are characterized by a fit of the institutional mix chosen to the societal context in terms of power dispersion. Hence, we demonstrate that the application of fs/QCA in a two-step manner helps to formulate and test equifinal and conjunctural hypotheses in medium-size N comparative analyses, and thus to contribute to an enhanced understanding of social phenomena.

运用法医学二代测序技术侦破19年久冷案

基于Y染色体STR(Y-STR)多态性的男性家系排查技术帮助全国各地破获了诸多冷案积案。然而对于出现明显降解的生物检材,或因检出Y-STR基因座数量过少而无法开展有效排查。STRSeqTyperY68男性家系精细化排查试剂盒,定位于二代测序技术,利用Mi Seq FGx二代测序平台可单管实现52个单拷贝Y-STR基因座、6个二拷贝Y-STR基因座、1个三拷贝Y-STR基因座和1个性别判定基因座的分型检测,并能同时支持STR长度和/或序列多态分型,全部基因座扩增子长度在350bp以下,且其中62个不大于300bp,适用于降解检材的检测。本文报道一起长达19年未破的强奸杀人案,用传统STR检测方法仅得到24个Y-STR基因座分型,部分300bp以上的Y-STR片段未检出,但通过二代测序方法使用STRSeqTyperY68试剂盒完整得到了67个Y-STR和1个性别基因座分型,从而帮助办案单位锁定了嫌疑人所在的男性家系,为案件侦破提供了关键技术支撑。

Fatal mephenesin intoxication

This report describes a death related to the abuse of and intoxication by mephenesin. To the best of our knowledge, this is the first report case of lethal intoxication involving solely mephenesin and reporting mephenesin blood concentrations. The victim was a 48-year-old woman found unconscious at home. Resuscitation was unsuccessful. Toxicological analysis was performed on a blood sample collected during resuscitation. The results being negative, the body was exhumed for an autopsy, which revealed bronchial inhalation syndrome. Analysis in a second laboratory has revealed the presence of mephenesin in samples collected during autopsy. No other drug/toxin was found, and alcohol was negative. Reanalysis of the peripheral blood collected during resuscitation found a mephenesin concentration of 15.81 microg/mL (15-fold greater that the maximum concentration that would result from a single intake of a 500 mg formulation). The pathologist has concluded on a bronchial inhalation syndrome consecutive to a mephenesin overdose as the cause of death. The manner of this death is discussed in the light of the toxicological hair analysis and the medical past of the victim.     

中国网络治理的社会符号学阐释

网络治理是一项复杂系统的社会工程,符号学因其系统性可为网络治理构建和完善提供学理支撑。网络治理和网络空间作为社会符号具有时空性和社会性,其意义会随着历史的变迁和解释主体的不同而变化,主要受历史条件、网络治理实践和国家利益等语境因素的制约。网络空间命运共同体和网络主权是中国网络治理符号系统的重要组成部分,要不断推动其从价值独特性符号向价值共识性符号的转变,即既保持中国特色,又获得国际社会的普遍共识。此外,结合马克思主义哲学理论,中国网络治理具有时代性、人民性、科学性、实践性和全球性,是马克思主义在网络空间治理领域的中国实践,是历史符号在新时代的全新阐释。
