US police officers’ knowledge regarding behaviors indicative of deception: Implications for eradicating erroneous beliefs through training

Abstract

The current study surveyed a random sample of Texas law enforcement officers (n?=?109) about their knowledge regarding behaviors indicative of deception. The officers were not highly knowledgeable about this topic, overall performing at a chance level in assessing how various behavioral cues relate to deception. Confidence in one's skill was unrelated to accuracy, and officers who reported receiving the most training and utilizing these skills more often were more confident but no more accurate in their knowledge of the behaviors that typically betray deception. The authors compare these results to previous studies that have examined officers’ beliefs in other countries and discuss the implication of these results in terms of developing future training programs that may debunk the common misconceptions that officers possess.     

Validation studies of the ParaDNA® Intelligence System with artificial evidence items

Short tandem repeat (STR) profiling is one of the mostly used systems for forensic applications. In certain circumstances, STR profiling is time-consuming and costly, which potentially leads to delays in criminal investigations. LGC (Laboratory of the Government Chemist, UK) Forensics has developed a robust STR profiling platform called the ParaDNA^® Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection. Here, we validated the ParaDNA intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Specifically, we tested the sensitivity and accuracy of the ParaDNA intelligence test, as well as the success rates for detecting mock samples and for use in case scenarios. Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles, especially for samples such as blood, saliva, and semen that contain ample DNA, indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.     

Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

体系、社会和国家:理解《美韩自由贸易协定》

2007年6月,美韩双方签署了《美韩自由贸易协定》。美韩之间为什么要签署该协定?该协定对两国国内分别产生了哪些影响?该协定为何至今没能获得美国国会的通过?针对上述问题,本文结合美国贸易政策理论,从体系、国家和社会三个层面对其进行了分析。《美韩自由贸易协定》的签署及其实施,在体系层面上将会为双方带来经济、政治和战略上的多重收益,而在社会层面上却产生了不同的反应。尽管由于国内经济困难和利益集团的掣制使得协定的通过还面临不小的阻力,但基于协定所蕴含的重要价值和两国政府对此认识的高度一致,协定获得通过只是时间上的问题。     

奥巴马"百日新政":内政视角

奥巴马就职后,面对经济危局,以力促经济复苏为施政目标,推出一系列反危机经济政策;同时,对小布什政府多项政策积极"纠偏",并凸显新能源、全面医疗改革、教育改革等"新政"重点.奥巴马的政策折射出"务实的自由主义"理念,既是形势使然,也是其自身哲学观的体现.目前,奥巴马拥有广泛的民意基础,得到多数舆论的支持,其执政黄金期可能持续到2010年11月中期选举前.但另一方面,奥巴马民主党色彩浓厚的政策主张具有一定政治风险,多管齐下的宏大改革计划面临诸多不确定性.     

独联体内部冒出新山头

今年5月22-23日,由乌克兰、格鲁吉亚、摩尔多瓦、阿塞拜疆4国组建的"古阿姆"组织在乌克兰首都基辅召开首脑会议,决定将"古阿姆"由非正式地区组织提升为国际性组织,并更名为"古阿姆民主与经济发展组织".这一组织的成立表明独联体内部新的山头形成,分裂趋势进一步加强.     

美国国防部长罗伯特·盖茨

2006年11月8日，美国总统布什宣布，提名老布什时期的中央情报局局长罗伯特·盖茨接替拉姆斯菲尔德，出任国防部长。这正是美国中期选举后的第二天，共和党因伊拉克战争在众议院落败。盖茨此次出山颇有临危受命的意味，老布什时期的国务卿、布什家族的好朋友贝克在推荐盖茨时就称赞他是“修理麻烦的好手”。上任近4个月的盖茨，其果敢、务实、灵活的风格令人印象深刻，但他能否力挽狂澜，带领美军走出伊拉克困境，仍是疑问。     

黑社会性质组织的含义和特征探析

黑社会性质组织犯罪是根据我国犯罪的发展态势在1997年修订的刑法中确定的一个法律概念.但是,在刑法理论上和刑事司法实践中,如何理解"黑社会性质组织犯罪是一种不明显、不典型的黑社会组织犯罪"的含义;如何界定"黑社会性质组织"的范围是关系到能否准确认定黑社会性质组织犯罪的最基本,最重要的问题.本文从黑社会的含义、黑社会性质组织的含义以及黑社会性质组织的特征三个方面对上述问题进行了阐述.
