Secondary Traumatic Stress and Burnout among Law Enforcement Investigators Exposed to Disturbing Media Images

This study examines the psychological impact of viewing disturbing media on investigators engaged in computer forensics work. Twenty-eight federal law enforcement personnel who investigate Internet child pornography cases completed measures of secondary traumatic stress disorder (STSD) and burnout. Substantial percentages of investigators reported poor psychological well-being. Greater exposure to disturbing media was related to higher levels of STSD and cynicism. STSD and burnout scores were related to increased protectiveness of family, reliance on co-workers, general distrust, and turnover intentions. On a positive note, investigators scored high in professional efficacy, indicating they feel their work makes a difference. Furthermore, personnel with supportive relationships scored lower on both STSD and burnout.     

Background survey of polyethylene in the Australian Capital Territory – A demonstration of variability in isotopic abundance values and their application to forensic casework

Plastics including adhesive tapes, cable ties, and packaging are common evidence types encountered in forensic investigations and casework. Traditional examination techniques such as Fourier Transform Infrared (FTIR) spectroscopy lack specificity and are unable to discern differences within the same polymer structures leaving the analyst with a generic identification. High quality manufacturing methods further amplify the limitations in detecting variability between samples. Isotope Ratio Mass Spectrometry (IRMS) has been shown to be a valuable technique in further discriminating plastics. Discrimination is achieved by analysing the relative abundances of stable isotopes within a sample, with differences detected in isotope ratios possibly attributed to the source of raw materials and fractionation during the manufacturing process. A survey of cling wraps and re-sealable zipper storage bags collected in the Australian Capital Territory was undertaken to assess the variability in carbon and hydrogen isotope ratios of different brands and samples. The results of this research are discussed, particularly with respect to within and between brand trends, and a case study is presented as an example of the value of including IRMS in a casework context.     

One Step at a Time: A Latent Transitional Analysis on Changes in Substance Use,Exposure to Violence,and HIV/AIDS Risk Behaviors among Female Offenders

The aim of this analysis is to identify latent subgroups of women based on substance use, exposure to violence, and risky sexual behaviors and quantify discrete stages of behavior change over time. Data comes from 317 women recruited from a Municipal Drug Court System in the Midwest. All participants were interviewed regarding their substance use and sexual behaviors, as well as their exposure to violence at baseline, a 4th-month follow-up, and an 8th-month follow-up. A latent transitional analysis (LTA), a longitudinal extension of a latent class analysis (LCA), was used to quantify discrete stages of behavior change. The results of our analyses revealed 4 distinct behavioral profiles in our sample: 1) women with high probabilities of risky sexual behaviors, exposure to violence, and crack/cocaine use, 2) women with a high probability of exposure to violence, and moderate sexual risk taking, 3) women characterized solely by a high probability of crack/cocaine use, 4) women with low probabilities of all factors. The proportion of women in latent statuses characterized by a high probability of crack/cocaine use did not substantially decrease over time. Women who experienced child sexual abuse, had a greater number of lifetime arrests, were older, and believed they had risky drug using behavior that needed changing at baseline were significantly more likely to be in higher-risk latent statuses. Targeted interventions tailored to crack/cocaine users, as well as a wide-spread need for trauma-informed interventions among females involved in the criminal justice system, are needed.     

Perceptions of suspect statements: a comparison of exposed lies and confessions

Confrontational interrogation techniques seek to produce a confession, while investigative interviews focus on information gathering and/or catching suspects in lies. Confessions obtained during interrogations are potent for securing a defendant’s conviction. However, the goal of investigative interviews is not to produce a confession, yet it is unknown if their outcome (e.g. exposed lies) is as effective in court as that of an interrogation (i.e. a confession). In two studies, mock jurors read case summaries wherein a defendant was accused of murder and terrorist activities. In both cases, the statement a defendant made during a police interview was manipulated: The defendant either lied or not and either confessed or not. Participants then rendered a verdict and were asked about the probative value of several pieces of supporting evidence. Results were similar across both studies with more convictions when the defendant lied, confessed, or did both relative to when the defendant produced a statement without lies and without a confession. Furthermore, we found that perceptions of supporting evidence mediated the effect of exposed lies on culpability, but this was not the case for confessions. These findings illustrate the positive qualities of presenting exposed lies in court, diminishing the need for a confession.     

Determining the order of deposition of natural latent fingerprints and laser printed ink using chemical mapping with secondary ion mass spectrometry

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) chemical mapping was used to investigate the order of deposition of natural latent fingerprints and laser printed ink on paper. This feasibility study shows that sodium, potassium and C₃H₅ positive ions were particularly abundant endogenous components of the natural fingerprints and also present in the paper examined, but were mostly absent in the laser printed ink. Mapping of these ions enables the observation of friction ridges from latent prints on the ink surface, only when a fingerprint was deposited above the layer of ink. As a demonstration of proof of concept, blind testing of 21 samples from three donors resulted in a 100% success rate. The sensitivity of this technique was investigated within this trial through the examination of up to fifth depletion fingerprints and ageing of up to 28 days. Migration of fingerprint and paper components to the ink surface, although observed with increased ageing time, was not found to compromise determination of the deposition sequence.     

“If this be living I'd rather be dead”: Enslaved youth,agency and resistance on an eighteenth century Jamaican estate

By the late eighteenth century, enslaved children and young adults had become vital components in the reproduction of Caribbean slavery. Yet the experiences of enslaved children and adolescents have rarely been the focus of scholarship. Indeed, the near-absence of scholarship on enslaved children and youth within the historiographies of slavery, childhood and family history is striking. While we know much about the structure of family life, gender roles, courtship, marriage, and parenting among the enslaved, we know far less about the material worlds of enslaved youth and adolescents. Childhood and adolescence represented critical stages in the lives of enslaved children for it was during these life-stages that young people were inculcated with the racialised ideologies of the wider social order, gained insight into the value systems of their society, were socialized into acceptance of their status as unfree peoples, and prepared for their future roles as labourers. Hence, their experiences of slavery were qualitatively different from those of adult slaves.

This paper explores some aspects of adolescent life on the Jamaican estate of Thomas Thistlewood in the late decades of the eighteenth century. Thistlewood, manager of a slave-pen, early recognised the importance of young people in furthering his ambitions to become master of his own estate, and his purchases of young people reflect that market-rational strategy. Thistlewood’s preference for a youthful labour force stemmed from his conviction that young people could be more easily made to submit to his authority than adult slaves. Yet, Thistlewood’s belief in the greater tractability of enslaved youth was often undermined, as his adolescent labour force frequently and forcefully tested the limits of his mastery and asserted their rights to freedom. Thistlewood’s journal not only offers rich insights into the processes of transformation of enslaved children to adolescents and mature adults, but it also sheds light on enslaved youth and their negotiations with, manipulations of, and resistance to the master–slave relationship. This paper argues then, that far from being the passive objects of planter mastery, enslaved youth were active agents in the shaping of their own histories. In exploring these issues, this paper reveals much of the contradictions and ambiguities of enslaved childhood, youth and adolescence.     

Joint evaluations of legislature and legislator

While much concern has been expressed about the accountability of quasi‐government there has been little empirical research on the subject. Similarly, the literature lacks a thorough assessment of the contribution of parliamentary questions to holding governmental institutions accountable. In this paper part of this gap in the literature is closed by measuring the extent to which a wide range of executive non‐departmental public bodies (ENDPBs) are held accountable by the use of questions tabled in the House of Commons. Questions asked to ministers in the Foreign Office and the Department for Education and Employment about ENDPBs they sponsor are assessed. A similar exercise is conducted on the agencies in these two departments and the results compared. In general, the partisan political atmosphere of the Commons, the apathy of many MPs, the size of the ENDPB sector and the rules governing questions mean that their contribution to the accountability of these bodies is relatively small. In particular, many specialist and technical bodies receive almost no scrutiny.
