GABA Receptors,Alcohol Dependence and Criminal Behavior

The aim of this study was to analyze the connection between alcohol dependence and criminal behavior by an integrated genetic–environmental approach. The research, structured as a case–control study, examined 186 alcohol‐dependent males; group 1 (N = 47 convicted subjects) was compared with group 2 (N = 139 no previous criminal records). Genetic results were innovative, highlighting differences in genotype distribution (p = 0.0067) in group 1 for single‐nucleotide polymorphism rs 3780428, located in the intronic region of subunit 2 of the GABA B receptor gene (GABBR2). Some environmental factors (e.g., grade repetition) were associated with criminal behavior; others (e.g., attendance at Alcoholics Anonymous) were inversely related to convictions. The concomitant presence of the genetic and environmental factors found to be associated with the condition of alcohol‐dependent inmate showed a 4‐fold increase in the risk of antisocial behavior. The results need to be replicated on a larger population to develop new preventive and therapeutic proposals.     

Estimating the Skull‐to‐Camera Distance from Facial Photographs for Craniofacial Superimposition

The overlay of a skull and a face image for identification purposes requires similar subject‐to‐camera distances (SCD) to be used at both photographic sessions so that differences in perspective do not compromise the anatomical comparisons. As the facial photograph is the reference standard, it is crucial to determine its SCD first and apply this value to photography of the skull. So far, such a method for estimating the SCD has been elusive (some say impossible), compromising the technical validity of the superimposition procedure. This paper tests the feasibility of using the palpebral fissure length and a well‐established photographic algorithm to accurately estimate the SCD from the facial photograph. Recordings at known SCD across a 1–10 m range (repeated under two test conditions) demonstrate that the newly formulated method works: a mean SCD estimation error of 7% that translates into <1% perspective distortion error between estimated and actual conditions.     

Purpose and behaviour: The Cuban missile conflict revisited

Fairly strong theoretical arguments posit that the use of force to achieve foreign policy objectives and the milita’ rization of society are part of a self‐amplifying feedback process. In spite of the rather coherent reasoning linking these two factors, little empirical work has attempted to demonstrate the strength of this postulated relationship. This analysis uses a system of equations to model this hypothesized feedback in the US and British societies during the 20th century. The findings presented below lend tentative support for the hypothesized feedback, though suggests that further verification might be facilitated through refinements in the operational indicators of violent foreign policy. Furthermore, the analysis demonstrates that systemic level variables contribute significantly to the propensity of the US and Great Britain to employ violence as a tool of foreign policy.     

Comparison of the Performance of Two Methods for Height Estimation

Abstract: In the case study, two methods of performing body height measurements in images are compared based on projective geometry and 3D modeling of the crime scene. Accuracy and stability of height estimations are tested using reconstruction images of test persons of known height. Given unchanged camera settings, predictions of both methods are accurate. However, as the camera had been moved in the case, new vanishing points and camera matches had to be created for the reconstruction images. 3D modeling still yielded accurate and stable estimations. Projective geometry produced incorrect predictions for test persons and unstable intervals for questioned persons. The latter is probably caused by the straight lines in the field of view being hard to discern. With the quality of material presented, which is representative for our case practice, using vanishing points may thus yield unstable results. The results underline the importance of performing validation experiments in casework.     

Agonal Sequences in Eight Filmed Hangings: Analysis of Respiratory and Movement Responses to Asphyxia by Hanging*

Abstract: It has been proposed that filmed hangings may hold the key to a better understanding of human asphyxia, and The Working Group on Human Asphyxia was formed to systematically review and compare these video recordings. This study analyzed eight filmed hangings. Considering time 0 to represent the onset of the final hanging, rapid loss of consciousness was observed (at 8–18 sec), closely followed by convulsions (at 10–19 sec). A complex pattern of decerebrate rigidity and decorticate rigidity then followed. Between 1 min 38 sec and 2 min 15 sec, muscle tone seemed to be lost, the body becoming progressively flaccid. From then on, isolated body movements were observed from time to time, the last one occurring between 1 min 2 sec and 7 min 31 sec. As for the respiratory responses, all cases presented deep rhythmic abdominal respiratory movements (last one between 1 min 2 sec and 2 min 5 sec).

随着网络信息技术的日新月异和迅猛发展,网络悄然成为许多人每天生活的一部分,人们不仅可以通过网络查收邮件、进行工作或学术研究、获取指令等,还可以通过网络观看电视电影、欣赏音乐和读书看报。但互联网在为人们提供快捷便利服务的同时,也给网络版权保护领域带来了前所未有的困难和挑战。特别是互联网应用方式的层出不穷,互联网信息共享技术发展的多元化,使得版权侵权案件纷至沓来,如何更好地实现在线视频网络服务商的“安全港原则”保护,这是一个值得认真思考的法律问题。     

讯问犯罪嫌疑人同步录音录像的证据学分析

讯问犯罪嫌疑人录音录像的证据类型是动态的,根据证明目的的改变而改变。在审查其证据能力的时候应当以“没有异议可采,有异议有限可采”为标准。面对证据立法上的滞后,应该加快立法完善的步伐。     

Forensic investigation of cross platform massively multiplayer online games: Minecraft as a case study

Minecraft, a Massively Multiplayer Online Game (MMOG), has reportedly millions of players from different age groups worldwide. With Minecraft being so popular, particularly with younger audiences, it is no surprise that the interactive nature of Minecraft has facilitated the commission of criminal activities such as denial of service attacks against gamers, cyberbullying, swatting, sexual communication, and online child grooming. In this research, there is a simulated scenario of a typical Minecraft setting, using a Linux Ubuntu 16.04.3 machine (acting as the MMOG server) and Windows client devices running Minecraft. Server and client devices are then examined to reveal the type and extent of evidential artefacts that can be extracted.     

Discretion and the Sex Dyad: Exploring the Interactive Effects of Offender and Victim Sex on Reporting and Arrest of One-on-One Assaultive Crime

Gender has been hypothesized to affect how violent offenders are treated within the criminal justice system, but studies have tended to ignore the role of the victim in decision making. This study explores the interactive effects of offender and victim sex (i.e., the sex dyad) on reporting and arrest of one-on-one assaultive crime. Using data from the National Crime Victimization Survey and National Incident-Based Reporting System, findings show that male-on-female offenses are reported to police more often than other dyads, but female-on-male offenses result in more arrests. Meanwhile, female-on-female offenses result in fewer arrests, despite nonsignificant differences in reporting. Implications of findings for theory and future research on gender discretion are discussed.
