Failings of Trauma‐Specific and Related Psychological Tests in Detecting Post‐Traumatic Stress Disorder in Forensic Settings

Judges and juries tend to be particularly impressed by test data, especially quantitative test data. Psychometric tests specific for assessing the presence of post‐traumatic stress disorder (PTSD) are commonly employed by forensic mental health evaluators. Most of these instruments, however, have been designed to detect PTSD in treatment or research, and not forensic, settings. Those who rely on these measures without adequate awareness of their often significant limits in correctly identifying malingering may induce finders of fact to inordinately confidently accept the presence of PTSD. This article reviews problematic structural and content components of trauma‐specific and related instruments used to evaluate PTSD and discusses the utility of specific techniques liable to be used in forensic settings to “fool” these measures.     

Diagnostic Value of PSA and AP Tests for the Detection of Spermatozoa in Postmortem Swabs from the Genital and Anal Region in Males

The aim of this study was to clarify whether positive results for prostate‐specific antigen (PSA) and acid phosphatase (AP) occur in postmortem swabs from the genito‐anal region in males (n = 80; 4 regions) and females (n = 20; 3 regions) and to calculate the positive predictive value (PPV) concerning the presence of spermatozoa. In male subjects, the highest incidence of positive test results was found in urethral swabs (PSA 76%, AP 71%) and the lowest frequencies appeared in perianal and rectal swabs (15–20%). Microscopic evaluation for spermatozoa was positive between 39% in urethral swabs and 1% in rectal swabs. PPV regarding positive identification of spermatozoa was 33.3% for PSA and 31.5% for AP. The combination of both tests yielded a PPV of 38.2%. In female cases, no spermatozoa were identified, and one case was PSA‐ and AP‐positive in perianal swabs. Our findings indicate that PSA and AP tests are of limited value for the postmortem detection of spermatozoa in male subjects.     

Understanding Variations of Soil Mapping Units and Associated Data for Forensic Science

Soil samples have potential to be useful in forensic investigations, but their utility may be limited due to the inherent variability of soil properties, the wide array of analytical methods, and complexity of data analysis. This study examined the differentiation of similar soils based on both gross (texture, color, mineralogy) and explicit soil properties (elemental composition, cation exchange, Fe‐oxyhydroxides). Soils were collected from Fallbrook and adjacent map units from Riverside and San Diego Counties in California. Samples were characterized using multiple techniques, including chemical extracts, X‐ray diffraction (XRD), and Fourier transform infrared spectroscopy. Results were analyzed using multiple analytical approaches to compare counties and land uses. Some analyses (XRD, extractions) were better at distinguishing among samples than others (color, texture). Ratios of rare earth elements were particularly useful for distinguishing samples between counties. This potential to “fingerprint” soils illustrates the usefulness of a comprehensive soil database for criminal investigators.     

Identification of Natural Images and Computer‐Generated Graphics Based on Statistical and Textural Features

To discriminate the acquisition pipelines of digital images, a novel scheme for the identification of natural images and computer‐generated graphics is proposed based on statistical and textural features. First, the differences between them are investigated from the view of statistics and texture, and 31 dimensions of feature are acquired for identification. Then, LIBSVM is used for the classification. Finally, the experimental results are presented. The results show that it can achieve an identification accuracy of 97.89% for computer‐generated graphics, and an identification accuracy of 97.75% for natural images. The analyses also demonstrate the proposed method has excellent performance, compared with some existing methods based only on statistical features or other features. The method has a great potential to be implemented for the identification of natural images and computer‐generated graphics.     

Who's Afraid of WikiLeaks? Missed Opportunities in Political Science Research

Leaked information, such as WikiLeaks’ Cablegate, constitutes a unique and valuable data source for researchers interested in a wide variety of policy‐oriented topics. Yet political scientists have avoided using leaked information in their research. This article argues that we can and should use leaked information as a data source in scholarly research. First, the methodological, ethical, and legal challenges related to the use of leaked information in research have been considered, concluding that none of these present serious obstacles. Second, how political scientists can use leaked information to generate novel and unique insights concerning political phenomena using a variety of quantitative and qualitative methods have been shown. Specifically, how leaked documents reveal important details concerning the Trans‐Pacific Partnership negotiations, and how leaked diplomatic cables highlight a significant disparity between the U.S. government's public attitude toward traditional knowledge and its private behavior have been demonstrated.     

PROFILING AND POLICE LEGITIMACY: PROCEDURAL JUSTICE,ATTRIBUTIONS OF MOTIVE,AND ACCEPTANCE OF POLICE AUTHORITY*

This paper reports the results of four studies that investigate racial profiling as an attribution about police motives. Each study explores, first, the types of police behavior that heighten or lessen the occurrence of profiling attributions and, second, the consequences of such attributions. Results support prior studies in finding that judgments about whether the police are profiling are associated with the level of public support for the police. The studies then extend the analysis of subjective profiling judgments by examining their antecedents. The findings support the procedural justice hypothesis that the fairness with which the police exercise their authority influences whether members of the public view the police as profiling.     

THE DELINQUENCY OF CHILDREN BORN TO YOUNG MOTHERS: RESULTS FROM THE ROCHESTER YOUTH DEVELOPMENT STUDY*

This paper examines the relationship between a mother's age at first childbirth and the delinquent behavior of her children. Using data from the Rochester Youth Development Study (RYDS), an ongoing longitudinal study of adolescent development, we found that children born to mothers who began childbearing at a young age were more prone to general delinquency, violence, and arrest than were children born to mothers who began childbearing when they were older. This “early first‐birth effect” was far larger in white and Hispanic families than in African‐American families. Mediating analyses found that the early first‐birth effect was most attributable to the unstable composition of families in which early childbearing occurs. That said, a substantial portion of the effect remains unmediated.     

SEX‐BASED DISPARITIES IN FELONY DISPOSITIONS BEFORE VERSUS AFTER SENTENCING REFORM IN OHIO*

Extending Koons‐Witt's (2002) study of whether sex‐based disparities in imprisonment likelihoods changed under sentencing guidelines in Minnesota, we examined similar models for Ohio with additional analyses of felony conviction likelihoods and sentence length for 5,472 felony defendants from twenty‐four trial courts. The main effects of a defendant's sex on imprisonment were significant during both periods (unlike the Minnesota findings), consistent with a chivalry perspective. Random coefficient models revealed that these effects were similar across the twenty‐four jurisdictions. Analyses also revealed significant postguideline reductions in sentence length disparities based on a woman's race and number of dependent children, yet increased disparities in imprisonment likelihoods postguidelines based on a woman's race and whether she was convicted on drug charges. These and other findings are discussed in the context of the Ohio legislature's implementation of a sentencing scheme that retains considerably more judicial discretion relative to Minnesota's template.     

STRICTLY LIABLE: GOVERNMENTAL USE OF THE PARENT–CHILD RELATIONSHIP AS A BASIS FOR HOLDING VICTIMS LIABLE FOR THEIR CHILD'S WITNESS TO DOMESTIC VIOLENCE

Studies estimate that between three and ten million children in the United States witness domestic violence annually. Although studies have demonstrated a co‐occurrence of domestic violence and child abuse, there is no concrete evidence to support the assumption that a child's exposure to domestic violence increases the risk to the child of abuse or neglect. Recently the New York State Court of Appeals determined that a child's witness to abuse does not suffice, in and of itself, to show that removal of the child is necessary or that removal is in the “best interests” of the child. Programs which have developed alternatives to presumptive removal understand the importance of viewing the interests of the battered parent and children as being in accord with each other rather than in opposition. Private and government sponsored programs have demonstrated some success in protecting the parent‐child relationship, ensuring the safety of both parent and child, and increasing accountability of batterers while reducing the necessity for removals. Alternative programs are less costly to the state than foster care, and emotionally less costly to the families.     

MENTORS AND CRIMINAL ACHIEVEMENT*

Much of the research focusing on conventional occupations concludes that mentored individuals are more successful in their careers than those who are not mentored. Early research in criminology made a similar claim. Yet contemporary criminology has all but ignored mentors. We investigate this oversight, drawing on Sutherland's insights on tutelage and criminal maturation and incorporating ideas on human and social capital. We argue that mentors play a key role in their protégés' criminal achievements and examine this hypothesis with data from a recent survey of incarcerated adult male offenders in the Canadian province of Quebec. In this sample, a substantial proportion of respondents reported the presence of an influential individual in their lives who introduced them to a criminal milieu and whom they explicitly regarded as a mentor. After studying the attributes of offenders and their mentors, we develop a causal framework that positions criminal mentor presence within a pathway that leads to greater benefits and lower costs from crime.
