An experimental study of compressed work schedules in policing: advantages and disadvantages of various shift lengths

Objectives  

The objectives of this research were to test the impacts of three shift lengths (8-, 10-, and 12-hour) on performance, health, safety, quality of life, sleep, fatigue, alertness, off-duty employment, and overtime among police.     

Domestic Violence Against Women: Systematic Review of Prevalence Studies

To systematically review the worldwide evidence on the prevalence of domestic violence against women, to evaluate the quality of studies, and to account for variation in prevalence between studies, using consistent definitions and explicit, rigorous methods. Systematic review of prevalence studies on domestic violence against women. Literature searches of 6 databases were undertaken for the period 1995 to 2006. Medline, Embase, Cinahl, ASSIA, ISI, and International Bibliography of the Social Sciences were searched, supplemented by hand searching of the reference lists from studies retrieved and specialized interdisciplinary journals on violence. A total of 134 studies in English on the prevalence of domestic violence against women, including women aged 18 to 65 years, but excluding women with specific disabilities or diseases, containing primary, empirical research data, were included in the systematic review. Studies were scored on eight pre-determined criteria and stratified according to the total quality score. The majority of the sudies were conducted in North America (41%), followed by Europe (20%). 56% of studies were population-based, and 17% were carried out either in primary or community health care settings. There was considerable heterogeneity both between and within geographical locations, health care settings, and study quality The prevalence of lifetime domestic violence varies from 1.9% in Washington, US, to 70% in Hispanic Latinas in Southeast US. Only 12% scored a maximum of 8 on our quality criteria, with 27% studies scored 7, and 17% scored 6. The mean lifetime prevalence of all types of violence was found to be highest in studies conducted in psychiatric and obstetric/gynecology clinics. Results of this review emphasize that violence against women has reached epidemic proportions in many societies. Accurate measurement of the prevalence of domestic violence remains problematic and further culturally sensitive research is required to develop more effective preventive policies and programs.     

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.     

The criminalization of immigration and the privatization of the immigration detention: implications for justice

In recent decades, the criminalization of immigration and the use of private prisons have increased in popularity. The criminalization of immigration and the privatization of prisons work hand in hand in shaping the American criminal justice response to immigration. Privatization creates a powerful opportunity for the social construction of the undocumented immigrant into a powerful potential source of revenue for for-profit corporations. Private prison corporations, such as Corrections Corporation of American and The GEO Group, stand to profit significantly from the private immigration detention center. Several investigative reports have focused on how these companies stand to profit, but little attention has been given to the psychosocial consequences that impact immigrant detainees and their families.
