Single source DNA profile recovery from single cells isolated from skin and fabric from touch DNA mixtures in mock physical assaults

The ability to obtain DNA profiles from trace biological evidence is routinely demonstrated with so-called ‘touch DNA evidence’, which is generally perceived to be the result of DNA obtained from shed skin cells transferred from a donor's hands to an object or person during direct physical contact. Current methods for the recovery of trace DNA employ swabs or adhesive tape to sample an area of interest. While of practical utility, such ‘blind-swabbing’ approaches will necessarily co-sample cellular material from the different individuals whose cells are present on the item, even though the individuals' cells are principally located in topographically dispersed, but distinct, locations on the item. Thus the act of swabbing itself artifactually creates some of the DNA mixtures encountered in touch DNA samples. In some instances involving transient contact between an assailant and victim, the victim's DNA may be found in such significant excess as to preclude the detection and typing of the perpetrator's DNA. In order to circumvent the challenges with standard recovery and analysis methods for touch DNA evidence, we reported previously the development of a ‘smart analysis’ single cell recovery and DNA analysis method that results in enhanced genetic analysis of touch DNA evidence. Here we use the smart single cell analysis method to recover probative single source profiles from individual and agglomerated cells from various touched objects and clothing items belonging to known donors. We then use the same approach for the detection of single source male donor DNA in simulated physical contact/assault mixture samples (i.e. male ‘assailant’ grabbing the wrist, neck or clothing from the female ‘victim’, or being in transient contact with bedding from the ‘victim’). DNA profiles attributable to the male or female known donors were obtained from 31% and 35% of the single and agglomerated bio-particles (putative cells) tested. The known male donor ‘assailant’ DNA profile was identified in the cell sampling from every mixture type tested. The results of this work demonstrate the efficacy of an alternative strategy to recover single source perpetrator DNA profiles in physical contact/assault cases involving trace perpetrator/victim cellular admixtures.     

Gorbachev's Economic Strategy: A Comment

Specialists from three countries report the results of survey research conducted during March-April 2000 in Dagestan. Questions addressed include identification with Russia and with Dagestan, confidence in local, regional, and federal institutions, perceptions of changes in the economy, politics, and cultural life, and perceived threats from external sources. Analysis also specifies attitudinal differences among ethnic groups and among other demographic categories within Dagestan.     

Predictors of criminal recidivism among male batterers

The present study examined recidivism risk factors in a sample of 320 male batterers attending community treatment. Recidivism was assessed by new charges for violence or for any offence during a 5-year follow-up period. The variables associated with recidivism among male batterers were similar to those found for other criminal populations (e.g. young, unstable lifestyle, substance abuse, criminal history). There was no evidence that potential offenders were deterred by expectations of negative consequences, either social (e.g. friends would disapprove) or official (e.g. being arrested, losing job). Maintaining positive relationships with treatment providers was associated with reduced recidivism.     

Predicting Attrition From Treatment Programs for Abusive Men

Attrition in male battering treatment programs is a serious problem. To keep clients in treatment, it is crucial to understand why they drop out. The current study examined the contribution of both client and program characteristics in predicting dropout from treatment programs for abusive men. Data were collected at intake from 306 abusive men who sought treatment at four different sites. The rate of preprogram attrition (from intake to the first treatment session) was higher in the program that had a lengthy waiting list (46%) than in the other programs amp lpar3%-13%). In-program attrition was more highly related to client characteristics than program characteristics (all programs had rates between 36% and 42%). Those men who dropped out after starting treatment tended to have unstable lifestyles (e.g., substance abuse problems, criminal history, unemployment) and to have inflicted more severe abuse than those who completed treatment. Results also supported a significant interaction between verbal aptitude and structure of program; men with low verbal aptitude were the most likely to drop out of an unstructured program. Possible strategies for preventing attrition are discussed.     

Promoting an Agenda for Nuclear Weapons Elimination: The Canberra Commission and Dilemmas of Disarmament

This paper examines the role of the Canberra Commission in terms of consolidating and influencing the agenda on international negotiations towards the elimination of nuclear weapons. The Commission's Report is significant for two main reasons. First, it represents a unique form of disarmament diplomacy by the Australian Government which combined the post-Cold War international climate of security cooperation with the foreign policy aspirations of an activist middle power. Second, the Report refutes the strategic, technological and political arguments against nuclear elimination in a comprehensive and convincing manner, arguing that without elimination, the world faces increased threats of nuclear proliferation and nuclear terrorism. This paper thus concludes that the Canberra Commission has been instrumental in strengthening the taboo against the possession, testing or use of nuclear weapons.     

Political Cultural Variations in State Economic Development Policy

The impact of political culture on state politics has been investigatedwidely, but little is known about the relationship between politicalculture and economic development policy, even though such policiesplay a prominent role in contemporary state politics. DrawingonDanielJ. Elazar's analysis of American political subcultures,I suggest that moralistic, individualistic, and traditionalisticvalues imply quite different strategies for promoting economicgrowth Empirical evidence shows that moralistic states pursuestrategies that emphasize solidarity, while individualisticstates employ policies that confer particularistic benefitson investors. For their part, policymakers in traditionalisticstates prefer exclusionary incentives that tend to reinforceexisting patterns of domination. Whether any of these strategiessucceed in realizing their cultural objectives remains to beseen; however, actions that positively affect economic performancemay lead to the erosion of cultural values by triggering migrationsthat bring new values into play.     

The relationships among self-blame, psychological distress, and sexual victimization

The primary purpose of this investigation is to assess the factor structure of survivors' attributions for previously experienced sexual assaults. Two hundred twenty-four female survivors of sexual assault responded to measures assessing attributions for past assaults, perceived avoidability of future assaults, frequency of past victimizations, and psychological distress. Factor analysis of the attributions measure suggested five underlying factors: perpetrator blame, characterological self-blame, situational factors and/or chance blame, behavioral self-blame, and societal blame. Results indicated that characterological self-blame, but not behavioral self-blame, was associated with negative outcomes, including increased psychological distress and increased frequency of past victimization. Although behavioral self-blame was associated with perceived avoidability of future assaults, it was not associated with lower psychological distress or reduced frequency of past victimizations.
