也门可能成为美国下一个反恐战场

近期，一名曾在也门受训的尼日利亚男子在美国制造圣诞节炸机未遂事件后，落户也门的基地组织阿拉伯半岛分支宣称对此负责，并进一步发出针对西方利益的恐怖威胁，也门国内安全局势骤然紧张。一时间，也门是否会成为美国新的反恐战场引起国际社会广泛关注。     

国外劳动力流动与教育互动及其启示——以英国、美国和德国为例

工业化进程中,发达国家在促进劳动力流动与教育互动经历了三个阶段:工业化发展初期发达国家靠已有教育基础推动了劳动力流动,工业化发展过程中劳动力流动促进了教育发展,教育的发展进一步推动了劳动力流动.发达国家工业化进程中劳动力流动与教育互动启示我们,应当高度重视劳动力流动与教育问题,解决劳动力流动与教育问题的着力点应当放在政府主导教育发展上,同时应当注意我国劳动力流动与教育互动问题的特殊性.     

Suicide using a hand grenade

The authors describe an unusual case of suicide that required particular attention to establish whether the victim was murdered, was preparing a terrorist attack or had committed suicide. Examination of the corpse and the crime scene, as well as testimonies, led the authors to determine the real cause of death, namely, an unusual method of suicide.     

Population data for Y-chromosome STR haplotypes from Piedmont (Italy)

Eight Y-chromosome STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393 and DYS385) were analysed in a sample of 236 unrelated males from four towns of Piedmont (Trino, Biella, Cavaglià, Postua). One hundred and fifty six different haplotypes were observed and 55 of them were not previously observed in the Y-STR Haplotype Reference Database (http://www.ystr.org/).     

Treatment of Gang Members Can Reduce Recidivism and Institutional Misconduct

Gang violence creates serious safety and security concerns in the community and prisons. Treated gang and nongang members recidivated significantly less in a 24-month follow-up than their untreated matched controls. Treatment consisted of high intensity cognitive-behavioral programs that follow the risk, need, and responsivity principles (Andrews & Bonta, 2003). The treated gang members who recidivated violently after treatment received significantly shorter sentences (i.e. they committed less serious offences) than their untreated matched controls. Untreated gang members had significantly higher rates of major (but not minor) institutional offences than the other three groups. Correctional treatment that follows the risk, need and responsivity principles appears able to reduce recidivism and major institutional misconduct. Effective correctional treatment should be considered as one of the approaches in the management and rehabilitation of incarcerated gang members.     

Fatal impalement with transfixion of the neck in a road traffic accident

The authors describe a singular case of fatal impalement due to penetration of a metal tube at the level of the neck in a victim of a road traffic accident. The man was traveling in the passenger seat ("death seat") of a car that hit the parapet of a bridge head on; death was attributed to hemorrhagic shock, which was brought on virtually instantly at the moment of impact.     

Anomalies and alterations of the hyoid-larynx complex in forensic radiographic studies

The authors illustrate the anatomic interest of the hyoid-larynx complex in the differential diagnosis of traumatic lesions, purely anatomic anomalies, and lesions resulting from natural causes. Forty larynges from corpses undergoing autopsy at the Institute of Legal Medicine of the University of Trieste were studied during the period May 1996 to May 2001. The larynges were excised and examined through radiographic magnification with dedicated mammographic equipment. Triticeous cartilages were evidenced in 12 (30%), they were bilateral in 7 (17.5%) and monolateral in 5 (12.5%). These cartilages were more frequent in men (8 out of 26; 31%) than in women, 4 out of 14 (28.5%).Total fusion of the body of the hyoid bone with the greater horns was revealed in 10 (25%), partial fusion in 4 (10%), and evident articular rima between the body and the greater horns of the hyoid bone in 14 (35%).The lesser horns of the hyoid bone were symmetrical in 29 (72.5%), asymmetric in 11 (27.5), absent in 1 (2.5%). While confirming the validity of the radiographic method used, we conclude that great care should be taken when diagnosing traumatic lesions of the hyoid-larynx complex. This diagnosis is often difficult to establish owing to the considerable frequency of anatomic anomalies of the complex.     

社会性别特征与领导风格性别差异实证研究

本文采用实证的方法探讨了男女两性管理者在个性特征、领导风格方面是否存在差异以及它们之间的相关关系。研究结果表明:在男性化特征上,男性表现的更为明显,但在女性化特征上,男女管理者并不存在显著的差异;在领导风格方面,男性更注重以任务为导向,但在以关心为导向方面,两性管理者不存在显著差异;男性化特征与以任务为导向的领导风格存在正相关关系,而女性化特征与以关心为导向的领导风格存在正相关关系。本文的研究可以为组织挑选合适的管理者提供一定参考。
