Commentary on Seagrave and Grisso: Impressions of the State of the Art

Seagrave and Grisso (2001) questioned the clinical-forensic utility of tests designed to assess juvenile psychopathy. They discussed potential problems with such tests and some avenues for future research. We agree with the points made by Seagrave and Grisso, but believe their critique did not go far enough. The state of the art with respect to the assessment of juvenile psychopathy is like an Impressionist painting: fine from a distance;but the closer you get, the messier it looks. We conclude that although tests of juvenile psychopathy measure something, it is impossible to be sure at this time they are actually measuring psychopathy.     

Validation of the InnoXtract™ DNA extraction method for bone,teeth, and rootless hair

Forensic casework samples often include human hairs, teeth, and bones. Hairs with roots are routinely processed for DNA analysis, while rootless hairs are either not tested or processed using mitochondrial DNA. Bones and teeth are submitted for human remains identifications for missing persons and mass disaster cases. DNA extraction from these low templates and degraded samples is challenging. The new InnoXtract DNA extraction method utilizes magnetic beads that are optimized to bind small DNA fragments, as small as 100 base pairs, to purify high-yield DNA from compromised samples. This validation study evaluates InnoXtract's ability to obtain amplifiable DNA from samples such as rootless hairs and skeletal remains. Studies performed include sensitivity, stability, repeatability, reproducibility, non-probative samples, and comparison to standard organic extractions. Sensitivity studies demonstrate average yield recoveries ranging from 53% to 100% and 73% to 85% for the InnoXtract hair and bone methods, respectively. Studies demonstrate consistent results across a range of sample types, such as insulted and un-insulted bone and teeth, as well as hair shafts from donors of various ages, gender, race, and hair characteristics. The InnoXtract bone method outperformed organic extraction. The method was successfully automated on a MagMAX™ Express-96, with recoveries over 70% relative to the manual version. InnoXtract has the potential as an automated high-throughput, high-yield bone extraction method with 6 h of total extraction time for up to 96 samples. The validation study results demonstrate that the InnoXtract kits produce high-yield and high-quality DNA from compromised bone, teeth, and hair shaft samples.     

The psychological effects of state socialization: IGO membership loss and respect for human rights

We present an interdisciplinary theory that considers how loss of membership in international organizations affects states’ human rights practices. Drawing mostly from social psychology and international relations research, we argue that states are socialized into the international community through a process of social influence, whereby they are incentivized to comply with group norms by the promise (threat) of social rewards (punishments). Social influence occurs when states form social bonds through interactions with other states. When social bonds are severed, fewer opportunities for social influence occur due to lower information to both the remaining states and the state that lost those social bonds. Thus, we hypothesize that the loss of membership from IGOs reduces incentives to comply with group norms and adversely affects human rights practices at home. A combination of propensity score matching/regression and autoregressive distributed lag (ADL) models on a global cross-section across the years 1978–2012 supports the theory. Specifically, losing at least one IGO membership leads to a long-run drop in human rights respect of about one quarter to one half standard deviation.     

Still Paying for the Past: Examining Gender Differences in Employment Among Individuals with a Criminal Record

Although many studies have examined employment outcomes of those with criminal convictions, no study to date has examined gender differences in employment outcomes of individuals with criminal convictions using a nationally representative sample of individuals from the United States. In this study, we use data from the 1997 National Longitudinal Survey of Youth to examine differences in employment after a criminal conviction for females and males. Results reveal that for women with a conviction, a drug offense and having dependent children limit the number of weeks of employment. For males, race, education, age at first conviction, and a subsequent conviction predict the number of weeks employed. Implications for policy and future research are discussed.     

Women in development: A critical analysis

In the early 1970s a general disenchantment with development efforts in Third World countries led to a search for alternative development strategies and a growing awareness that women, like the poor, were peripheral to the development efforts of major aid donors. In 1972 the United Nations designated 1975 as International Women's Year, highlighting the need to involve women in issues of economic development. During the past 20 years the 'women in development' approach, which seeks to recognise and integrate women in aid policies and programmes, has been incorporated into the aid practice of most development agencies. This paper traces the efforts of large aid agencies over the past two decades to integrate women into their aid programmes and discusses the main limitations and weaknesses of the WID approach.     

What I Have Learned About Countering Terrorismϕ

As a counterterrorism officer of thirty years, I have a healthy respect for history. Yet I also know that hindsight changes what you think about what you once thought. My observations about terrorism trends and counterterrorism strategies over the years are not what they once were. What I think now is more aligned with how I feel, and therefore, much clearer. Until recently, I had always based my observations about national security in my experiences as a counterterrorism analyst. I have come to realize that the lessons I believe are the most valid are not a result of my career experiences but from allowing the rest of my life to shed light on my career.     

The effect of weight on the femur: a cross-sectional analysis

This study assessed whether obesity significantly affects femoral shape. Femora of 121 white men were divided into two weight classes based on body mass index (BMI) of the deceased. Five external anteroposterior (AP) and mediolateral (ML) measurements were taken at consistent percentages of diaphyseal length. These were then subject to statistical tests. After controlling for age, multivariate statistics show a significant (p<0.05) effect of BMI on the femur, with the greatest significance in ML measurements. T-tests confirm these dimensions are significantly larger in the overweight (p<0.05). The effect of BMI on size-transformed and shape-transformed variables was also evaluated, with ANOVA results showing a significant BMI effect on ML size (p<0.05), but not shape. Significant size-transformed ML variables were then subject to discriminate function analyses with a cross-validation correction. Results show a correct classification rate of 88% in normal weight and 77% in overweight individuals.
