A simulation for exploring the effects of the "trait list" method's subjectivity on consistency and accuracy of ancestry estimations

The nonmetric "trait list" methodology is widely used for estimating ancestry of skeletal remains. However, the effects of the method's embedded subjectivity on subsequent accuracy and consistency are largely unknown. We develop a mathematical simulation to test whether variation in the application of the "trait list" method alters the ancestry estimation for a given case. Our simulation explores how variations in (i) trait selection, (ii) number of traits employed, and (iii) ancestry choice thresholds affect the ancestry estimation of an unidentified skeleton. Using two temporally and geographically diverse samples, the simulation demonstrates that trait selection, trait quantity, threshold choices, and the exclusion of high-frequency traits had minimal effect on estimation of general ancestry. For all data sets and Runs, Accuracy(AS) was maintained above 90%. The authors close with a discussion on the logistical issues present when choosing traits, and how to avoid ancestry bias.

警衔“督晋督”信息化培训现状调查分析与有效对策

警衔晋升培训工作是公安教育中的重要组成内容,为了深入研究督晋督警衔晋升人员信息化应用的现状,本文采用自制调查问卷,针对女50岁以上、男55岁以上,来自辽宁省14个市的两期督晋督培训班的354名学员计算机信息化应用情况进行问卷调查。通过分析可以看出,随着全省公安系统信息化的建设和发展,公安民警在思想上已经越来越重视学习计算杌的相关知识,但由于年龄、硬件条件等客观原因,参加督晋督培训的学员在计算机信息化应用方面也存在一些问题。因此,有效地了解参训学员的计算机知识的掌握情况是做好信息化应用培训工作的重要前提。     

THE INFLUENCE OF E‐GOVERNMENT ON ADMINISTRATIVE DISCRETION: THE CASE OF LOCAL GOVERNMENTS IN EGYPT

One important but often understudied area of research in public administration is the effect of e‐government on administrative discretion. This article examines e‐government factors that influence administrative discretion through a survey of local governments. The focus of this study is on Egyptian local governments, which are using e‐government to modernise public service delivery. Through a survey of administrative officials in these governments, this study found evidence that e‐government factors of collaboration and organisational change influenced administrative discretion. Other common factors noted in the literature such as size of the local government and demand by citizens for e‐government did not register an effect on administrative discretion. The results of this study imply that local governments should do more to enhance e‐government to reduce administrative discretion, especially in the area of increasing collaboration.

How important are interview methods and questionnaire designs in research on self-reported juvenile delinquency? An experimental comparison of Internet vs paper-and-pencil questionnaires and different definitions of the reference period

There has been relatively little change over recent decades in the methods used in research on self-reported delinquency. Face-to-face interviews and self-administered interviews in the classroom are still the predominant alternatives envisaged. New methods have been brought into the picture by recent computer technology, the Internet, and an increasing availability of computer equipment and Internet access in schools. In the autumn of 2004, a controlled experiment was conducted with 1,203 students in Lausanne (Switzerland), where “paper-and-pencil” questionnaires were compared with computer-assisted interviews through the Internet. The experiment included a test of two different definitions of the (same) reference period. After the introductory question (“Did you ever...”), students were asked how many times they had done it (or experienced it), if ever, “over the last 12 months” or “since the October 2003 vacation”. Few significant differences were found between the results obtained by the two methods and for the two definitions of the reference period, in the answers concerning victimisation, self-reported delinquency, drug use, failure to respond (missing data). Students were found to be more motivated to respond through the Internet, take less time for filling out the questionnaire, and were apparently more confident of privacy, while the school principals were less reluctant to allow classes to be interviewed through the Internet. The Internet method also involves considerable cost reductions, which is a critical advantage if self-reported delinquency surveys are to become a routinely applied method of evaluation, particularly so in countries with limited resources. On balance, the Internet may be instrumental in making research on self-reported delinquency far more feasible in situations where limited resources so far have prevented its implementation.

关于警察职业倦怠现状的调查

从湖南各地市随机抽取681名警察进行问卷调查,目的在于了解警察的职业倦怠状况,以期为预防和干预警察职业倦怠提供现实依据。结果发现：从整体看,湖南省警察情感耗竭达中等程度,人格解体程度较高,成就感低落也较高。在人口统计学变量上,不同文化程度和不同婚姻状况在职业倦怠三个维度上无显著性差异;男女警察在情感耗竭和人格解体上达到极其显著性差异;不同来源的警察在人格解体维度上达到显著差异;不同警种的警察在情感耗竭上达到显著差异;不同年龄的警察在人格解体上达到了非常显著的差异;不同职务的警察在情感耗竭和成就感低落上达到非常显著的差异。     

侵犯知识产权犯罪案件情况与法律适用问题调查

侵犯知识产权犯罪案件在实体法适用层面存在共犯认定规则不统一,单位犯罪司法认定存在偏差,知识产权犯罪交叉竞合定性差异较大,数额认定争议较大等问题。在程序法适用层面存在管辖设置不尽合理,调查取证困难,涉外程序规则缺失,被害人（单位）提供假冒产品鉴定证明的法律效力存在瑕疵等问题。有必要通过知识产权犯罪刑法解释的优化以及程序操作规范的完善,以应对知识产权犯罪法律适用过程中出现的疑难问题。     

人民警察核心价值观问卷调查与分析

2009年11月＂人民警察核心价值观研究＂课题组先后对我省十几个市、县公安局200名民警进行了问卷调查,基于调查所示,我们认为：人民警察核心价值观是引领公安队伍建设的一面旗帜,是规范民警执法行为的一杆标尺,是减少警察职务犯罪的一把利器,其对于凝练新时期的公安精神、形成警察队伍的主流意识与道德导向具有重大的现实意义;鉴于警察组织的政治性、法律性、社会性和人民性等特点,人民警察核心价值观的基本内涵是忠诚、责任、公正、为民;人民警察核心价值观的养成需要教育引导、个体修习和实践培育等途径的多管齐下,以收到良好的合力效应。
