Trichophyton Mentagrophytes Perforates Hair of Adult Corpses in the Gaseous Period*

Abstract: Despite the substantial literature on mycology, there are still limited reports of the interaction between fungi and human hosts in the postmortem period. Thus, the main goal of this study was to investigate the in vitro perforation test using Trichophyton mentagrophytes on hair from adult corpses in the postmortem period (gaseous period). The protocol was carried out with positive (prepubescent children’s hair) and negative controls (healthy adult hair) as well. One strain of Trichophyton rubrum was also used as a negative perforation control. Perforations were found in all the hair samples from corpses and prepubescent children after 12–14 days exposure to T. mentagrophytes and were absent in the hair samples of healthy adults. Furthermore, hair perforation was not observed with T. rubrum. Our preliminary findings suggest the use of T. mentagrophytes as a potential marker of the death interval in forensic science.     

民企掌门人:新生代的成长与挑战

我国第一代民营企业家经过30多年的发展,现已陆续进入交接班阶段。作为民企掌门人的第二代是一个特殊的群体,他们与第一代创业者有着血缘和财富上的共通性,有着在思维方式、创业精神、经营思路和发展理念上的差异性。他们肩负着对父辈的传承和超越,他们正试图寻找家族式企业与现代企业制度的契合点,以他们所具有的开阔视野和知识胆识,在更广泛的领域参与市场分工与竞争。民企第二代青年企业家的成长关乎民企的未来,也关乎中国市场经济的健康发展。关注民企第二代青年企业家成长是全社会的责任。     

村民待遇问题的法律探析

集体所有是一种政治意义上的所有制,而不是法律意义上的所有制;自治结果的正义与民法上的公平正义是两个不同的范畴,有着不同的正义标准;改革集体所有制以期解决当前问题;村民待遇案件问题是一个政治问题,而非法律问题,不应通过司法程序来解决。     

农民工返乡创业行为的影响机制

本文采用山西、河北两省返乡创业农民工的深度访谈资料,运用扎根理论方法,分析了转型期中国农民工在返乡创业过程中所面临的内外部条件。在此基础上,探讨内外部因素形成的压力和动力,以及农民工对自身拥有的生计资本整合和政策环境对创业行为的影响。研究发现：压力和动力是农民工返乡创业的前因变量,生计资本整合是二力（压力和动力）影响创业行为的中介变量,而政策支持则是生计资本整合影响创业行为的调节变量,在此基础上,本文提出了农民工返乡创业行为的影响机制模型。     

东南亚国家的南海问题研究:现状与走向

从2009年南海问题再次升温以来,在国际学术界南海问题研究中,东南亚学者开始扮演着越来越重要的角色。通过相关的文献分析和解读可以看到,东南亚学者的南海问题研究主要侧重于南海地区制度建设、南海问题国际法解读、东盟在南海问题中的角色以及南海问题新的和平倡议四个方面,而且研究内容开始向南海问题的国内影响因素、危机管理机制的建立等方向发展。深入全面把握东南亚国家南海研究的动向有助于我们知己知彼,吸收借鉴,利用更有针对性的研究加强南海问题公共外交,提高在这方面的国际话语权。     

Diel Activity and Effect of Carcass Decomposition on the Attractiveness to the Forensically Important Species Oxelytrum Discicolle (Coleoptera: Silphidae)†

Oxelytrum discicolle is a carrion beetle commonly found in the Neotropical region, mainly associated with cadavers and carcasses. Information on behavior related to the likelihood of cadaver colonization is scarce. We performed two field experiments in peri‐urban forest in Brazil in order to strengthen our knowledge on O. discicolle behavior. In the first experiment, we assessed the preference for piglet carcasses at different stages of decomposition offered simultaneously in two seasons, dry and rainy, while in the second experiment we investigated the diel activity of adults. A total of 493 adults were collected in the experiments. A significantly higher abundance was detected in the rainy season. There was a marked preference for carcasses at advanced stages. Adults exhibited a typical nocturnal behavior, the number trapped at night was 17 times greater than those collected during the day. Oxelytrum discicolle is nocturnal species that prefers carcasses in advanced stage of decomposition.     

Forensic Gait Analysis and Recognition: Standards of Evidence Admissibility

Gait is one biological characteristic which has attracted strong research interest due to its potential use in human identification. Although almost two decades have passed since a forensic gait expert has testified to the identity of a perpetrator in court, the methods remain insufficiently robust, considering the recent paradigm shift witnessed in the forensic science community regarding quality of evidence. In contrast, technological advancements have taken the lead, and research into automated gait recognition has greatly surpassed forensic gait analysis in terms of the size of acquired datasets and demographic variability of participants, tested variables, and statistical evaluation of results. Despite these advantages, gait recognition presents with different problems which are yet to be resolved. Therefore, courts should treat gait evidence with caution, as they should any other form of evidence originating from disciplines without fully established codes of practice, error rates, and demonstrable applications in forensic scenarios.     

政策网络的两种分析途径及其影响

政策网络是运用网络主义来分析政策过程的一种理论框架。不同的学派对它有不一样的理解。在学术界都承认政策网络是一种在分析政策过程中利益集团与政府关系的方法基础上,分别从利益中介和治理两个不同的分析途径对政策网络进行研究。不同的分析途径导致了不同的研究方向,但是以上的分歧深化了对政策网络本身的深刻理解。
