Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using two drug administration models

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.     

从项目嵌入到组织社会:村级集体经济发展的新趋势及其类型学研究

发展和壮大村级集体经济是乡村振兴战略的重要内容。既有研究在探讨村级集体经济问题时较多地聚焦于其功能和目的、历史与现实、发展原则和要求,而较少关注到村级集体经济的发展趋势及其在不同村庄所呈现出的异质性特征。基于"项目嵌入-公众参与"的二维分析框架和浙北J市S镇的田野调查发现:新时期村级集体经济发展出现了由依赖纵向国家项目嵌入向组织和激活横向社会网络转变的新趋势,其发展形式呈现出政社耦合型、社会嵌入型、政治嵌入型和双重脱嵌型四种理论类型。村级集体经济发展类型上的差异也导致了其在村庄治理实践中发挥的分配、互惠、悬浮、兜底保障等不同功能,以及国家治理机制上的分殊。此外,村级集体经济的发展在不同类型的村庄面临着不尽相同的内外限制性条件。     

Women and Lancashire Conservatism between the Wars

The activism of women Conservatives helped Tory democracy to adapt and survive in inter-war Lancashire at a time when it was under strain due to the arrival of Labour as a significant electoral force. This article utilises the surviving records of the party in Lancashire to examine the various ways that women entered, navigated, justified and expanded their membership and function in inter-war Conservatism. It acknowledges the limits on women's advancement and influence, but it also highlights how some women made significant progress in rising through the party structures, and how women's branches facilitated this political mobility. It challenges the assumption that women Conservatives were preoccupied with sociability and discussing domestic issues, and reveals their contribution to the electoral success of the party at local level, and interaction with Lancashire's distinct tradition of Conservatism.     

Evaluating the Effectiveness of Adopting Open Educational Resources in an Introductory American Government Course

In this article, we present findings from a grant-funded initiative to replace traditional, proprietary textbooks with an open content textbook under a Creative Commons license in the introductory American government course (POLS 1101) at Middle Georgia State University. We find that the use of an open content textbook led to somewhat negative effects on student learning outcomes and student course satisfaction, although the associated lower textbook cost increased textbook accessibility to students. We conclude with some suggestions to those adopting textbooks in this course and to the wider discipline regarding measures that may lead to more unequivocally positive outcomes than those experienced in this study.

制度权威缺失的原因探究

“徒法不足以自行”。当前,在我国的制度建设进程中,树立制度应有权威是一项非常紧迫的任务。制度权威缺失有其内外部原因:制度权威和政治权威缺乏相容性、正式制度和非正式制度缺乏相容性是其外部因素;制度与制度体系的自身不足是其内部因素。
