跨文明研究:把握住世界学术基本动向与学术前沿

跨文明研究已经成为一个世界性的学术思潮。跨文明研究是一种强调对不同文明之间的异质性的研究。比较文学的跨文明研究的最终目的是追求在不同文明的异质性基础上产生的一种互补性。跨文明研究以追求一种“异中之和”或“和而不同”的文化理想而区别于全球化思潮。当前可以从3个学术前沿的问题来切入和推进中国比较文学的跨文明研究:一是“送去主义”或“发现东方和文化输出”的理论问题;二是比较诗学领域中体现出来的异质文明的不可通约性和可通约性研究问题;三是跨文明研究视野中的中国文化“失语症”问题。     

The Distribution of Household Property Crimes

Previous studies have established that repeat victimizations occur more frequently than would be expected if households within a particular area were victimized randomly. This implies that characteristics of the household affect the victimization rate. Even controlling for these characteristics, we find that a Poisson model does not capture the distribution of victimizations because repeat victimizations are more concentrated than it would indicate. This leads us to adopt the negative binomial generalization of the Poisson model. Our analysis uses sociodemographic attributes of the household and community-level characteristics to predict victimizations, with the victimization data being the observed number of property crime victimizations from the 1992 British Crime Survey. The negative binomial generalization is found to be highly statistically significant and the crime concentration it implies becomes much more marked as the predicted number of victimizations increases.     

供应链社会责任管理与异质性企业社会责任行为——基于中国企业数据的实证研究

该文利用12个城市1000多家中国制造业企业调查数据，采用Logit模型和似不相关回归方法，考察了供应链社会责任管理与异质性对企业社会责任的影响。研究发现，企业异质性（规模、生产率等）与企业社会责任认知和履行正相关；在其他条件不变的情况下，供应链社会责任管理与企业社会责任的履行呈显著正相关系；政府监管促进了企业在劳工权益保护、环境管理和产品质量等社会责任的履行；加入行业协会或公益性组织的企业，在社会责任行为上存在“同群效应”。因此，结合企业异质性在供应链管理中推行社会责任，会促使企业履行社会责任。     

Repeat victimization among adolescents and young adults

Prior research has shown that victimization incidents are disproportionately concentrated among relatively few victims and that prior victimization is a consistent predictor of future risk. This paper expands existing knowledge on victimization by describing temporal patterns of risk and by developing and testing alternative explanatory models of the link between past and future risk. Analyses based on panel data from the National Youth Survey support both state dependence and heterogeneity interpretations of the correlation in risk over time. In other words, prior victimization predicts future risk in part because it alters something about the individual, and because it indicates an unmeasured propensity for victimization that persists over time. The theoretical implications of these findings, including the feasibility of a victim labeling perspective, are discussed.An earlier version of this paper was presented at the annual meeting of the American Society of Criminology, Phoenix, 1993.An exception to this lack of attention is the vast literature in the area of domestic abuse.     

Microbial metagenome profiling using amplicon length heterogeneity-polymerase chain reaction proves more effective than elemental analysis in discriminating soil specimens

The combination of soil's ubiquity and its intrinsic abiotic and biotic information can contribute greatly to the forensic field. Although there are physical and chemical characterization methods of soil comparison for forensic purposes, these require a level of expertise not always encountered in crime laboratories. We hypothesized that soil microbial community profiling could be used to discriminate between soil types by providing biological fingerprints that confer uniqueness. Three of the six Miami-Dade soil types were randomly selected and sampled. We compared the microbial metagenome profiles generated using amplicon length heterogeneity-polymerase chain reaction analysis of the 16S rRNA genes with inductively coupled plasma optical emission spectroscopy analysis of 13 elements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Si, and Zn) that are commonly encountered in soils. Bray-Curtis similarity index and analysis of similarity were performed on all data to establish differences within sites, among sites, and across two seasons. These data matrices were used to group samples that shared similar community patterns using nonmetric multidimensional scaling analysis. We concluded that while chemical characterization could provide some differentiation between soils, microbial metagenome profiling was better able to discriminate between the soil types and had a high degree of reproducibility, therefore proving to be a potential tool for forensic soil comparisons.     

股东关系维度代理问题及其治理机制研究

股东“异质化”的现实演进和股东关系的弱式平等使得股东关系维度代理问题日渐成为公司治理的重点与难点。股东关系维度代理问题在中国股份公司中有其特殊性,如股东间的代理关系情境极其复杂、控制权私利攫取成本较低、中小股东消极主义尤为明显、多元维度代理问题相互交织等。公司立法必须注重强化自治和利益平衡,多措并举构建防范股东关系维度代理问题的结构性治理机制。     

环保督察与空气质量改善:立足城市情境的效应异质性分析

作为生态环境保护领域的一项重大制度创新,中央环保督察已经成为党和政府推动生态文明建设的重要政策工具。然而,对于中央环保督察能否改善空气质量,尤其是其效果的可持续性,尚存在诸多争议。立足于匹配后的地级市数据评估中央环保督察对空气质量改善的平均效应,结果表明中央环保督察尽管在短期内显著改善了空气质量,其长期效应并不显著。然而,借助基于模型的递归分解法和随机森林法进一步发现:中央环保督察的长期效应存在显著的情境差异性:中央环保督察对于空气污染较重的城市具有长期改善效应,且东部城市尤为明显;一个城市的经济发展水平越高,中央环保督察效应越具有长效性;政府规模和财政自主性对中央环保督察效应起到截然相反的调节作用:前者的扩张会削弱长期效应,而后者的提升则会强化长期效应。揭示城市情境对督察效应的调节作用,有助于深化学界对中央环保督察长效性的条件认识,也为进一步完善该制度、提升其效能提供了重要的思路。     

基于Ion Torrent PGM~(TM)测序系统的人mtDNA全测序分析

目的应用Ion Torrent PGM~(TM)测序系统对人线粒体DNA(mitochondria DNA,mtDNA)全序列进行分析检测,研究不同组织间mt DNA序列差异情况。方法通过法医尸体检验采集6名无关个体的组织样本,包括胸腔血液、头发、肋软骨、指甲、骨骼肌和口腔上皮。使用4对引物对线粒体全序列进行扩增,应用Ion Shear~(TM)Plus Reagents试剂盒和Ion Plus Fragment Library试剂盒等构建文库,并在Ion Torrent PGM~(TM)测序系统上进行线粒体基因组全序列测序,并针对异质性位点和在HVⅠ区域突变位点,进行Sanger测序验证。结果所有样本的全基因组mtDNA都扩增成功,6名无关个体分属于6种不同的单倍型,同一个体不同组织之间mtDNA存在异质性差异。异质性位点和HVⅠ区域突变位点采用Sanger测序结果均得到验证。通过Kappa统计方法进行一致性检验后发现,相同个体不同组织的mtDNA序列检验结果仍具有较好的一致性。结论本研究所采用的人线粒体基因组全序列的测序检验方法,可以检测出同一个体不同组织间mtDNA的异质性差异,该差异具有较高的一致性,该结果对mtDNA在法庭科学中的应用具有指导作用。     

恩格斯思维与存在同一性观点辨析——兼与俞吾金教授商榷

思维与存在同一性问题是哲学基本问题的重要方面,我们认为,马克思恩格斯是在坚持唯物主义前提下,以承认思维与存在既有同质性又有异质性为基础的同一性,而不是俞吾金教授所说的,恩格斯是坚持黑格尔同质性基础上的思维与存在同一性。     

The discipline of difference: Ethnolinguistic heterogeneity and corporal punishment

The minority threat hypothesis contends that growth in the size of a given minority population along with the ensuing competition for social and political resources will threaten existing social power arrangements. Regarding punishment specifically, the hypothesis states that dominant groups will support coercive measures to keep minority populations sufficiently oppressed. Using the minority threat hypothesis as our theoretical foundation, we posit that the more heterogeneous a population, the more social control will be necessary to maintain societal equilibrium for those in power. In effect a more personal, physical, and visceral response to criminal behavior will be deemed necessary in countries with high levels of fractionalization. This more focused form of social discipline will manifest as corporal punishment. Comparing modalities of punishment against varying population characteristics, we find that countries with higher levels of ethnic, linguistic, and religious fractionalization are more likely to employ corporal punishment against criminal offenders.
