Application of MALDI‐TOF MS for Estimating the Postmortem Interval in Rat Muscle Samples

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.     

The Impact of Negative Publicity on Police Self-legitimacy

High-profile events involving police use of force in various cities throughout the US and internationally have garnered enormous media coverage and demonstrated the importance of police-community relations. To date little empirical attention has focused on how such events may negatively impact police officers. Using survey data from 567 officers, this study considers whether perceptions of negative publicity are adversely related to officers’ sense of self-legitimacy (i.e. the confidence they have in their authority). Findings revealed officers who felt less motivated as a result of negative publicity expressed less self-legitimacy. However, the degree to which officers felt their job had become more dangerous as a result of negative publicity was not significantly related to self-legitimacy. These findings increase our understanding of the sources of self-legitimacy and reveal that negative publicity surrounding law enforcement presents a unique challenge to officers’ confidence in their authority, which can have important implications for the community.     

The talk–listen–respond (TLR) model of representatives on Twitter

Despite the existing research on how elected representatives use Twitter, there are few comparative studies and none that considers Israel, a country that differs from most democracies in its electoral system. This study has two levels of analysis. The first is the country level, in which the author compares and explains how representatives in four countries – the US, Canada, Australia and Israel – use the talk, listen and respond model to achieve their goals. The second is the individual level, in which the author analyses how personal characteristics such as gender and age, and political characteristics such as seniority and membership in the opposition or coalition affect the frequency of use of Twitter. Using quantitative data, it is demonstrated that representatives vary in the frequency of their use of Twitter. On the country level, Australian representatives use Twitter more often than their counterparts in other countries. On the individual level, first-term members, members of the opposition, and older representatives use Twitter more often than those with more seniority, coalition members, and younger legislators.     

行政的变迁与行政法学范式转换 --《论公共行政与行政法学范式转换》述评

石佑启教授的专著<论公共行政与行政法学范式转换>从现代公共行政改革与发展着眼,从范式转换的高度全面而系统地梳理了行政法与公共行政的演进关系,概括了传统的行政法学范式及其面临的挑战,进而提出必须突破传统的理论框架进行范式转换,从而勾勒了在现代公共行政背景下的新的行政法学图景,为进一步完善行政法学理论体系,促进行政法治制度创新,更好地解决公共行政变革中产生的法律问题,提出了诸多富有创建性的观点,填补了行政法学研究上的一些空白.     

温病湿热证湿重于热动物模型舌的病理观察

目的：观察温病湿热证湿重于热动物模型舌的病理改变。方法：复制温病湿热证湿重于热动物模型,观察大鼠舌的病理改变,并设湿热组、脾虚组、正常组进行比较。结果：湿重于热组、湿热组固有层乳头密度及核分裂相频数显著增多,与正常组及脾虚组比较差异有显著性;湿重于热组和湿热组固有层均出现炎症、充血及水肿,前者水肿更甚,后者则充血明显。结论：舌的病理改变,可能是湿热证型中舌苔变化的病理基础,并可作为判定湿热轻重的指标之一。     

送变电企业文化建设的现状与对策研究

企业文化是指在一定的社会经济条件下通过社会实践所形成的并为全体成员遵循的共同意识、价值观念、职业道德、行为规范和准则的总和,是一个企业或一个组织在自身发展过程中形成的以价值为核心的独特的文化管理模式。中国加入WTO后,正式融入了世界经济主流和经济全球化进程。作为基础产业的电力基建行业,将直面全球化的竞争。企业的经营环境将发生重大而深刻的变化,生存环境将更加复杂,基建市场、企业内部资源等更大范围内的竞争变得十分激烈。送变电企业只有加强企业文化建设,教育和引导员工转变观念,不断加固员工的忠诚和归属感,不断提升员工技术水平和素质,才能留住人才,稳住人心,企业才能发展,才能保证改革的顺利进行。

犯罪构成模型论

犯罪构成是立法者依据一定的利益需求与价值观念而将生活中之危害行为加以类型化形成的 ,表现为通过刑法规范所确认的认定犯罪之规格、标准或最低度条件———本文称之为模型。它同构成犯罪的事实 (原型 )是不同层面之范畴。注释刑法学应以刑法条文中静态存在的模型意义上的犯罪与刑罚为研究对象。同两大法系的构成体系相比较 ,在现阶段国情下我国几十年所形成的通说体系具有直观、简单、易操作的特点 ,并无重新构造之当务必要。
