Age determination of blood spots in forensic medicine by force spectroscopy

We present a new tool for the estimation of the age of bloodstains, which could probably be used during forensic casework. For this, we used atomic force microscopy (AFM) for high-resolution imaging of erythrocytes in a blood sample and the detection of elasticity changes on a nanometer scale. For the analytic procedure we applied a fresh blood spot on a glass slide and started the AFM detection after drying of the blood drop. In a first step, an overview image was generated showing the presence of several red blood cells, which could easily be detected due to their typical "doughnut-like" appearance. The consecutively morphological investigations in a timeframe of 4 weeks could not show any alterations. Secondly, AFM was used to test the elasticity by recording force-distance curves. The measurements were performed immediately after drying, 1.5 h, 30 h and 31 days. The conditions were kept constant at room temperature (20 degrees C) and a humidity of 30%. The obtained elasticity parameters were plotted against a timeline and repeated several times. The elasticity pattern showed a decrease over time, which are most probably influenced by the alteration of the blood spot during the drying and coagulation process. The preliminary data demonstrates the capacity of this method to use it for development of calibration curves, which can be used for estimation of bloodstain ages during forensic investigations.     

Assessment of rape-supportive attitudes and beliefs in college men: development, reliability, and validity of the rape attitudes and beliefs scale

Discussed is the development and psychometric analysis of a measure of rape-supportive attitudes and beliefs called the Rape Attitudes and Beliefs Scale (RABS), intended for the use with college men. Items were developed from a literature review of "rape myths" that were correlated to some measure of sexual aggression. An exploratory factor analysis using only male participants revealed five factors: a) justifications for sexual aggression based on women's behavior, b) belief that women should hold more responsibility for sexual assault, peer c) pressure/need for sexual status and misreading women's sexual intent, d) acceptance of the use of alcohol and coercive tactics to acquire sexual compliance, and e) dislike for the feminine and acceptance of traditional gender roles. Initial reliability and validity studies were favorable for the RABS, including evidence that these factors were positively related to measures of sexual aggression. Each factor demonstrated differential power to predict sexual aggression, with justifications being the most powerful. Implications for counseling and education are discussed.     

Trends in Psychological/Psychiatric Injury and Law: Continuing Education, Practice Comments, Recommendations

This literature review of the major topics in the field of psychological/psychiatric injury and law is aimed at developing commentary for practice in the area. The field is a fast-developing one, with over ten major topics that it needs to integrate. In particular, the present review focuses current work on: law (evidence, tort); forensic psychology; assessment and testing; psychological injuries (posttraumatic stress disorder, chronic pain, traumatic brain injury, other); the APA DSM-5 draft (Diagnostic and statistical manual of mental disorders; American Psychiatric Association 2010); malingering; causality; multicultural considerations; disability; the American Medical Association (AMA) Guides to the evaluation of permanent impairment (Rondinelli et al. 2008); models; and treatment. At the end of each section of the article, practice comments introduce critical issues in applying the research to psychological work in the area. Whether undertaking tort evaluations, disability, and treatment plan assessments or treating individuals with psychological injuries, the professional needs state-of-the-art information in all the areas listed in order to remain scientifically informed, comprehensive, and impartial. The article concludes with recommendations for an integrated field in psychological/psychiatric injury and law, study in the field, research in its major areas, best practice policies, for example in assessment and treatment, and model building.     

Time in Law's Domain

Law bends the past of a community's common life towards its future. 1 Precedent is one of law's favored tools for doing the bending, and legal systems that assign precedent a starring role seem especially mindful of time. Yet, mindfulness of time goes far deeper into law's DNA. It is not limited to the doctrine of precedent or unique to common‐law jurisdictions. Recognizing that time is an elemental dimension of human experience and basic ordering principle of practical agency, law utilizes and orders time. Temporality is essential to law's distinctive mode of governance and guidance.     

Personal networks and crime victimization among Swedish youth

We combine routine activity theory, lifestyle-victimization theory, and a social network perspective to examine crime victimization. In particular, we study to what extent crime victimization is associated with having close contacts who have been victimized and/or who engage in risky lifestyles. We use the data (collected in 2014) of 1,051 native Swedes and 1,108 Iranian and Yugoslavian first- or second-generation immigrants in Sweden who were all born in 1990. They were asked to describe their personal characteristics, various behaviours, and past personal experiences with crime victimization, as well as those of the five persons with whom they most often spend their leisure time. Our findings support the network perspective: crime victimization is negatively associated with the number of close contacts an individual mentions but is substantially more likely for those who have many close contacts who have themselves been victimized. In terms of a risky lifestyle that may enhance the likelihood of being victimized, we found only that individuals who get drunk frequently were at somewhat higher risk of being victimized. To guard young individuals against crime victimization, it might thus be worthwhile to focus more on with whom they associate than on their potentially risky lifestyles or attitudes.     

The MMPI-2 L Scale as a Measure of Impression Management After Receiving Test Information: a Case Report

Normally, high scores on the MMPI L (Lie) scale are associated with underreporting of symptoms. However, in certain circumstances, such as disability applications and personal injury litigation, individuals may be motivated to convey elevated symptomatology in combination with exaggerated portrayals of virtuosity and truthfulness. Information about tests may help guide this impression management pattern. The current case report illustrates these points and demonstrates that acquired information can motivate an individual, under the right circumstances, to increase their endorsement of uncommon virtues. Clinicians and forensic examiners are encouraged to remain alert to how test information interacts with an individual’s presentation motives.     

The contributions of higher education to ethical behavior in law enforcement

This paper examines the relationship between higher education and ethical practice among law enforcement officers. The spoken and unspoken values of the academic world and their influence on college educated police is explored. The specific values of studying options available to law enforcement practitioners in an academic setting is reviewed, e.g., the role of a policeman acting as a witness at a trial. The areas where college experience can appreciably increase the ethical awareness of policemen is presented.
