Characteristics of male patients admitted to an adolescent secure forensic psychiatric hospital

This paper examines the characteristics of a group of 64 young men, who were consecutively admitted to Bluebird House, an NHS mixed gender, adolescent forensic, medium secure hospital. The characteristics examined focus on the young men’s clinical presentations, as informed by the Millon Adolescent Clinical Inventory, and their ICD10 (WHO 1992) diagnoses. The paper also examines the males’ route into, and out of, Bluebird House, as well as their risk profiles, especially with regards to others, as informed by Structured Assessment of Violence Risk in Youth findings and staff recorded incidents. Correlational analysis is performed to try and understand this population, with statistically significant findings highlighted. The discussion considers the trajectory for some of these young men into adult personality disorders, their presentation and prognosis compared to their female counterparts, and how their presentation contrasts with adult male forensic populations.     

The Voting Motivations of Conservative Parliamentarians in the Conservative Party Leadership Election of 2001

This article examines the voting motivations of Conservative parliamentarians in the final parliamentary ballot of the Conservative party leadership election of 2001. By constructing a data set of the voting behaviour of Conservative parliamentarians in the final parliamentary party ballot, this article seeks to test a series of hypotheses relating to the ideological disposition and political characteristics of the candidates vis-à-vis their electorate. The article examines how and why the eliminative parliamentary ballot ensured that the party membership was presented with a face-off between the europhile, Kenneth Clarke, and the eurosceptic, Iain Duncan Smith, and why the modernising and socially liberal Michael Portillo was rejected. It will demonstrate that while arguments based on ideological factors are valid, the political characteristics of age and career status were also significant motivational influences that contributed to the rejection of Portillo and the delaying of the modernisation of the Conservative party.     

Chemical enhancement of footwear impressions in blood on fabric – Part 1: Protein stains

A range of protein stains were utilised for the enhancement of footwear impressions on a variety of fabric types of different colours with blood as a contaminant. A semi-automated stamping device was used to deliver test impressions at a set force to minimise the variability between impressions; multiple impressions were produced and enhanced by each reagent to determine the repeatability of the enhancement. Results indicated that while most protein stains used in this study successfully enhanced impressions in blood on light coloured fabrics, background staining caused interference on natural fabrics. Enhancement on dark coloured fabrics was only achieved using fluorescent protein stains, as non-fluorescent protein stains provided poor contrast.A further comparison was performed with commercially available protein staining solutions and solutions prepared within the laboratory from the appropriate chemicals. Both solutions performed equally well, though it is recommended to use freshly prepared solutions whenever possible.     

Chemical enhancement of footwear impressions in blood deposited on fabric — Evaluating the use of alginate casting materials followed by chemical enhancement

Most footwear marks made in blood on a surface such as fabric tend to be enhanced in situ rather than physically recovered using a lifting technique prior to enhancement. This work reports on the use of an alginate material to recover the impressed footwear marks made in blood and deposited on a range of fabric types and colours. The lifted marks were then enhanced using acid black 1 and leuco crystal violet with excellent results.This presents a new method for the lifting and recovery of blood impressions in situ from crime scene followed by subsequent mark enhancement of the lifted impression.     

Can We Identify Bad Cops Based on History? Base Rates of Historical Markers in Law Enforcement Pre-employment Evaluations

While psychometric police selection processes have progressively evolved, the efficacy of simple background information has not been extensively evaluated. This study examined the utility of base rate information to predict job performance among law enforcement officers. Pre-employment historical markers from bad hires were compared to good hires from a large sample of 1536 officers. Of this sample, 205 officers were categorized as bad hires if they were arrested, had greater than five misconduct episodes, or were terminated for cause within 5 years following hire. Base rates of 40 pre-employment history variables were compared for good and bad hires. Analysis of markers showed that bad hires had a significantly higher frequency of markers across family factors, mental health variables, conduct problems, and criminal justice outcomes compared to good hires. Among the largest differences were history of multiple physical altercations, outpatient psychiatric treatment, and events related to previous law enforcement employment such as employer reprimands, suspensions, or fitness for duty evaluations. Many other intuitive markers occurred too infrequently to analyze or showed no significant difference between good hires and bad hires in law enforcement settings. Base rates in addition to psychological test data are necessary aspects of the police pre-employment evaluation.     

Further Validation of the Test of Memory Malingering (TOMM) Trial 1 Performance Validity Index: Examination of False Positives and Convergent Validity

Assessment of performance validity is an essential part of a neuropsychological evaluation, with the inclusion of two or more performance validity tests (PVTs) becoming routine practice. Considering the time to administer multiple tests, there has been some support for use of the Test of Memory Malingering (TOMM) Trial 1 (T1) as an independent, “one and done” PVT. Notably, cutoffs for TOMM T1 need further validation, with an emphasis on minimizing false-positive classifications among those with bona fide cognitive impairment. In a clinically referred sample of 127 veterans, this study examined the role of cognitive impairment in TOMM performance and the utility of a TOMM T1 as an independent PVT. Examinees were administered the TOMM and three additional PVTs as part of a comprehensive neuropsychological battery. Sixty-eight percent of examinees were classified valid (35% of valid examinees were cognitively impaired). TOMM T1?≤?40 had excellent observed sensitivity (83%) and specificity (93%) overall, with minimal false-positive classification. TOMM T1 was also significantly correlated and concordant with other memory-based PVTs. Given score ranges and failure rates for TOMM T1?≤?40 among those with neurological/neurocognitive conditions, scores in the 37–40 range may merit administration of additional TOMM trials to maximize accuracy in identifying valid-cognitively impaired versus noncredible performance. Otherwise, an abbreviated TOMM administration (i.e., only T1) using a cutoff of ≤?40—in conjunction with one or more additional PVTs—may be sufficient for detecting noncredible/invalid test performance in the absence of known or suspected neurological/neurocognitive disorders.
