我国“公务员热”的效应分析及政策建议

当前“公务员热”成为社会关注的焦点之一,这一现象一方面有利于我国公务员制度建设,同时也从侧面反映了我国社会中存在的诸多问题。为此,必须通过扩大就业和社会保障、完善公务员制度建设、转变政府职能等来规避这一现象的负效应。     

测验与访谈在公正性上的较量——关于警察心理测试公正性的探讨

由于职业的特殊性 ,警察的心理素质对其工作有着特殊的重要性。近年来 ,对警察心理素质的日益关注使得许多单位在选拔警察时都加强了对其心理素质的考核 ,但人们在热衷于心理测试的同时 ,却对测试中的公正性缺乏足够的关注。通过对访谈与测验两种测试方式在公正性上的比较 ,探讨警察心理测试技术中的公正性问题颇具现实意义。     

血色原微量分光法血痕确证试验

目的探讨血色原微量分光法作为血痕确证试验的可行性。方法用离心分离的检材浸洗液代替检材,与改良高山试剂进行血色原反应,用微量分光光度计测定吸收光谱,判断检材是否含血。在优化参数的基础上,用倍比稀释的粗制人血红蛋白测定方法的灵敏度,用常见疑似血液/血斑,以及不同保存时间、不同基质的血斑测定方法的特异性和检材适应能力。结果用血色原微量分光法,仅血液(斑)具有415nm、525nm和555nm三个吸收峰组成的特异光谱,与常见疑似血液/斑没有交叉。反应2min,上样2.5μL,稀释1000倍的人血可稳定获得三峰光谱。通过延长浸洗时间、设置基质对照,10年陈旧血纱、有色布上的血斑等均可有效确证。三个吸收峰的高度与检液的血含量呈正相关,且525nm和555nm的吸光度变化趋势一致(y=0.523 2x+0.027 4,R2=0.997 1)。结论血色原微量分光法灵敏度高、特异性强,快速简便,可纳入DNA检验流程之中,在实际检案中有较好的应用前景。替代传统结晶法用于教学,更符合当前学生技能和意识的培养要求。     

Immigrants into Citizens

This paper examines the citizenship test which is part of the UK naturalisation process. The test is based on the government publication Life in the United Kingdom: A Journey to Citizenship. A detailed analysis of its two editions (2004 and 2007) reveals that the conception of the citizen, and the picture of British government and society underlying each are very different. There is, additionally, a mismatch between the rationale offered for the Life in the United Kingdom test and what the latter can in fact test: the attitudes and civic virtues mentioned in the rationale are untestable on-line. A society which aspires to be a democracy, it is argued, needs to scrutinise carefully the fairness and democratic appropriateness of its procedures for admitting new citizens.     

Citizenship Tests: A Comparative, Communitarian Perspective

The history, nature and scope of citizen naturalisation tests are briefly examined in this article, as well as their political and social applications. A comparison of tests from the United States, the United Kingdom, the Netherlands and Germany highlights the ways in which these tests are used as immigration controls rather than as a way to establish preparation for citizenship. The difference in the content of the tests also reveal alternative conceptions of citizenship including authoritarian, liberal and neo-communitarian.     

EXCEL多元回归分析在痕迹数据处理上的应用

在痕迹检验技术中,很多推算公式是由回归分析预测法得出的。多元回归分析预测法的计算,虽然可以用常用计算器进行统计,但是数据复杂繁琐,工作量较大。Excel是一种办公系统软件,运用它的强大数据分析功能,只输入一次原始数据,而后全部以鼠标操作即可自动生成回归方程。文章以一组足迹数据分析为例,首先介绍相关分析,然后建立回归模型,最后计算出相关的回归方程。

武汉洪山“2004·1·8”盗案心理测试剖析

2004年1月8日,武汉市洪山区朱女士的30万元现金在轿车后备箱被盗,洪山警方接警调查后盗案是否成立存在着两种相反意见,湖北警官学院对朱女士采用测谎仪测试得出盗案事实成立的结论。洪山警方迅速立案调查,又由湖北警官学院对嫌疑对象作测谎测试,作案人刘海军浮出水面,在铁证面前,刘海军交代作案经过,全案告破。心理测试在侦破此案中发挥了十分重要作用,其经验是多方面的,但同时也有教训,走过一些弯路。     

A 2‐Year Study of Δ 9‐tetrahydrocannabinol Concentrations in Drivers: Examining Driving and Field Sobriety Test Performance,,

From November 1, 2010 through November 30, 2012, 1204 whole‐blood samples were confirmed to contain THC alone or in combination with other drugs out of nearly 5000 Orange County, California, drivers suspected of driving under the influence of drugs. The goal of this study was to examine police reports and drug recognition expert evaluations of THC‐positive samples within this 2‐year time frame to determine whether there is a correlation between whole‐blood THC concentrations and field sobriety tests performance on DRE and non‐DRE evaluations. The FSTs prove to be sensitive to impairment by marijuana although as suspected, the findings of this study did not find a correlation between performance on field sobriety tests and the concentration of THC tested in whole‐blood samples. Driving behaviors were also examined and found to be similar to those seen in alcohol impairment. Future studies examining DRE findings are needed to confirm the results.
