Investigative studies into the recovery of DNA from improvised explosive device containers

Apprehending those who utilize improvised explosive devices (IEDs) is a national priority owing to their use both domestically and abroad. IEDs are often concealed in bags, boxes, or backpacks to prevent their detection. Given this, the goal of the research presented was to identify IED handlers through postblast DNA recovery from IED containers. Study participants were asked to use backpacks for 11 days, after which they served as containers for pipe bombs. Eleven postdeflagration backpack regions likely to be handled were swabbed and analyzed via mini-short tandem repeats (miniSTRs) and alleles were called blind. An experimental consensus method was examined in which profiles from all regions were considered, to help identify spurious drop-in/out. Results were correct for all loci, except one that remained ambiguous. The results show that recovering DNA from IED containers is a viable approach for aiding in the identification of those who may have been involved in an IED event.     

Predicting discharge in forensic psychiatry: the legal and psychosocial factors associated with long and short stays in forensic psychiatric hospitals

In Germany, both the number of patients treated in forensic psychiatric hospitals and the average inpatient treatment period have been increasing for over thirty years. Biographical and clinical factors, e.g., the number of prior offences, type of offence, and psychiatric diagnosis, count among the factors that influence the treatment duration and the likelihood of discharge. The aims of the current study were threefold: (1) to provide an estimate of the German forensic psychiatric patient population with a low likelihood of discharge, (2) to replicate a set of personal variables that predict a relatively high, as opposed to a low, likelihood of discharge from forensic psychiatric hospitals, and (3) to describe a group of other factors that are likely to add to the existing body of knowledge. Based on a sample of 899 patients, we applied a battery of primarily biographical and other personal variables to two subgroups of patients. The first subgroup of patients had been treated in a forensic psychiatric hospital according to section 63 of the German legal code for at least ten years (long-stay patients, n=137), whereas the second subgroup had been released after a maximum treatment period of four years (short-stay patients, n=67). The resulting logistic regression model had a high goodness of fit, with more than 85% of the patients correctly classified into the groups. In accordance with earlier studies, we found a series of personal variables, including age at first admission and type of offence, to be predictive of a short or long-stay. Other findings, such as the high number of immigrants among the short-stay patients and the significance of a patient's work time before admission to a forensic psychiatric hospital, are more clearly represented than has been observed in previous research.     

DNA collection from used toothbrushes as a means to decedent identification

ABSTRACT: Comparison of DNA profiles is often used in verifying the identification of deceased human beings when other easier, quicker, and less expensive means to identification are not possible. Fifty-five adult subjects divided into 3 groups provided a used toothbrush along with a small bloodstain control for DNA analysis and comparison. Results indicate that there is no significant difference in the quantity and quality of DNA recovered from a toothbrush that has been used for 1 month versus 3 months versus random periods. The results of this study confirm earlier conclusions that a used toothbrush is a reliable source of antemortem DNA from a putative decedent. The use of aviation snips to remove a small portion of the toothbrush head provides an easy, inexpensive method of obtaining a sample for DNA extraction. The authors recommend this method as a standardized technique for use in forensic DNA laboratories.     

Factors Predicting Relationship Satisfaction,Investment, and Commitment When Women Report High Prevalence of Psychological Abuse

Relationship satisfaction, investment, and commitment in women experiencing extensive psychological abuse were examined to determine predictive factors. Participants were the top quartile of a national sample of women in conflictual relationships (N = 81) experiencing psychological maltreatment. Relationship satisfaction, investment, and commitment were each used as criterion variables with conceptually related factors as the predictors (e.g., reactions to the psychological abuse; mental health indicators; personality variables; perceived harm; problematic relationship schemas; response styles; demographics). These relationship markers were differentially predicted within this group of women. Three independent clusters of women, based on patterns of satisfaction, investment, and commitment scores, were compared regarding physical abuse, reactions to psychological abuse, ratings of perceived harm, endorsement of relationship schemas, psychological distress variables, and personality variables. The cluster of women reporting higher satisfaction, investment, and commitment in these seemingly aversive relationships frequently demonstrated differences from the other two clusters. Implications for clinical applications are discussed.

The Dynamics of Self-Esteem: A Growth-Curve Analysis

Research on adolescent self-esteem has been inconsistent regarding development patterns and processes, with some scholars concluding that self-esteem is a static construct and others concluding that it is a dynamic construct. A potential source of this inconsistency is the lack of attention to intraindividual changes in self-esteem across adolescence and to gender-specific developmental patterns. Building on previous research, we use a growth-curve analysis to examine intraindividual self-esteem changes from early adolescence to early adulthood. Using 7 years of sequential data from the Family Health Study (762 subjects ages 11–16 in Year 1), we estimated a hierarchical growth-curve model that emphasized the effects of age, life events, gender, and family cohesion on self-esteem. The results indicated that age had a curvilinear relationship with self-esteem suggesting that during adolescence self-esteem is a dynamic rather than a static construct. Furthermore, changes in self-esteem during adolescence were influenced by shifts in life events and family cohesion. These processes were different for males and females, particularly during early adolescence.     

The role of competition in health care: a Western European perspective

The Federal Trade Commission and Department of Justice 2004 report Improving Health Care: A Dose of Competition expresses a clear allegiance to competition as the organizing principle for health care. In Europe, by contrast, the key organizing principle of health care systems is solidarity. Solidarity means that all have access to health care based on medical needs, regardless of ability to pay. This is not to say that competition is not important in Europe, but competition must take place within the context of solidarity. This article critiques the report from a European perspective, describes the role of competition in Europe (focusing in particular on European Union law), and suggests that the United States could learn from the European perspective.     

Severity of intimate partner violence and occurrence and frequency of police calls

This article evaluates whether female victims of severe physical, psychological, or sexual intimate partner violence (IPV) call police more often than other abused women. Abused women (431) reported frequency of contacting police (dependent variable), nature and severity of IPV experienced, and characteristics of themselves and their perpetrator (explanatory variables). A two-part regression model estimated likelihood of police contact among all participants and rate of contact among callers. Women with severe physical or psychological IPV or injury were more likely to call police than were other abused women. Among callers, women made 96% more calls if a weapon was involved, 58% more if they were severely sexually abused, and 40% more if they were severely physically abused. Women with children at home made 32% more calls. These results delineate the level and types of IPV and other characteristics of homes that make single and repeat calls to police.     

Lay persons' versus psychologists' judgments of psychologically aggressive actions by a husband and wife

Literature assessing knowledge of and attitudes toward social issues has demonstrated that mental health professionals and lay persons often differ greatly. To add to the normative information in the field of psychological abuse and to determine whether the differences previously found between mental health professionals and lay persons extend to this field, a sample from each group rated psychologically aggressive items by a husband toward his wife. For the 102 items, psychologists were more likely to label the behaviors as "psychological abuse," but this tendency was due to psychologists considering the behaviors as either "always" or "possibly" abusive, whereas lay persons demonstrated a bimodal response pattern of rating the behaviors as "always" or "never" psychological abuse. Lay persons were much more likely than psychologists to rate items high in terms of severity level, however. The two groups used different contextual factors for determining that a behavior was psychological abuse when they initially were uncertain that it was abusive.
