Using iPhones? to Enhance and Reduce Face-to-face Home Safety Sessions within SafeCare?: An Evidence-based Child Maltreatment Prevention Program

Innovative handheld technologies are changing the possibilities for public health interventions. The present research describes a preliminary examination of the iPhone? when used as an assessment tool and an enhancement to an evidence-based, in-home child safety intervention. Three families with young children received an augmented version of the Safety module of SafeCare, a home-visiting child maltreatment prevention program. Specifically, parents were trained to use an iPhone to video rooms in their homes, as well as communicate feedback, logistics, and safety content between the home visitor and parent. The effectiveness of iPhone and video was examined using a multiple baseline design across in-home settings replicated across families. Home hazards were reduced dramatically across rooms and across participants. Face-to-face time of the home visitor was progressively reduced and replaced by video data collection. These data suggest smartphones are promising for data collection and for augmenting face-to-face interactions. Implications for reducing costs as smartphones become increasingly ubiquitous and for engaging and retaining participants are discussed.     

Detection of deception with fMRI: Are we there yet?

A decade of spectacular progress in functional magnetic resonance imaging (fMRI) technology and systems neuroscience research has so far yielded few changes in our daily lives. The dearth of clinical applications of this prolific and academically promising research tool began raising the eyebrows of the public and the research funding agencies. This may be one of the reasons for the enthusiasm and interest paid to the growing body of literature suggesting that blood oxygenation level‐dependent (BOLD) fMRI of the brain could be sensitive to the differences between lie and truth. The word ‘differences’ is critical here since it refers to the often‐ignored core concept of BOLD fMRI: it is only sensitive to differences between two brain states. Thus, available studies report using fMRI to discriminate between lie and truth or some other comparative state rather than to positively identify deception. This nuance is an example of the extent to which applied neuroscience research does not lend itself to the type of over‐simplification that has plagued the interpretation of fMRI‐based lie detection by the popular press and the increasingly vocal academic critics. As an early contributor to the modest stream of data on fMRI‐based lie detection, I was asked by Dr Aldert Vrij to write a piece in favour of fMRI‐based lie detection, to be contrasted with a piece by Dr Sean Spence presenting an opposite point of view ( Spence, 2008 ). This seemingly straightforward task presented two hurdles: having to respond to the popular as well as scientific view of what lie detection with fMRI is and present a wholly positive view of evolving experimental data.     

Postmortem Measurement of Human Chorionic Gonadotropin in Vitreous Humor and Bile

Abstract: Postmortem human chorionic gonadotrophin (HCG) blood assay can confirm postmortem diagnosis of pregnancy or document situations in which HCG levels are elevated. In some cases, however, blood sampling is not possible at autopsy. In this study, HCG was quantified by enzyme‐linked fluorescent assay (ELFA) in the bile (n = 5), vitreous humor (n = 4), and postmortem blood (n = 4) of five pregnant women. There were no false negatives in the pregnant subjects (n = 5) or false positives in controls (n = 34), enabling this test to be recommended for routine use in forensic contexts in which the detection of elevated HCG levels could be of interest.     

Perceptions about memory reliability and honesty for children of 3 to 18 years old

Purpose. To examine the relationship between perceived memory characteristics and age. Method. Participants rated the reliability and honesty of children's memory for one of two events. The children's ages varied from 3‐ to 18‐years‐old. Results. Participants (N = 612) believed that memory reliability increased with age, but the observed effect was non‐linear. Perceived reliability increased rapidly for children from 3 to 6 years. After this, male participants believed memory reliability increased, but less than in early childhood. Female participants did not think memory reliability increased in middle childhood and adolescence. Further effects involving type of event, age of participant, and the gender of the eyewitness were observed for honesty and the relationship between these attributes and beliefs in guilt. Conclusions. These findings stress the need for more research on development trends of memory in middle childhood and adolescence.     

Glycated hemoglobin: a useful post-mortem reference marker in determining diabetes

Glycated hemoglobin (HbA(1c)) has been demonstrated to be a useful marker for long-term glucose control in diabetes. This parameter characterizes each non-enzymatic fixation of glucose on hemoglobin. It is a useful test in addition to periodic glycemia controls since it reflects the mean glycemia of the past 60 days. We studied the conservation of HbA(1c) at 4 degrees C as a function of time with different anti-coagulants and preservatives (3, 6 months, 1 year). A total of 106 tests were performed using the high performance liquid chromatography (HPLC) method dedicated to the semi-automatic analysis of HbA(1c) (Bio-Rad) and we applied the method in forensic cases. Conservation at 4 degrees C was good for as long as 3 months in blood samples collected with fluoride and 6 months in samples collected in a dry or in a heparinized tube. In non-diabetic subjects, HbA(1c) reference values obtained from forensic samples were identical to those of living controls (3.5-6.25% of total hemoglobin). All positive HbA(1c) results were confirmed by a medical evaluation. This method was successfully applied to five forensic cases. In cases of increased acetonemia, acetone or isopropanol are easily measured. However, in some unexplained post-mortem circumstances, increased HbA(1c) permits to differentiate alcoholic or starvation ketoacidosis from the diabetic cases. Glycated hemoglobin should, therefore, be considered the forensic marker of choice in the post-mortem diagnosis of a diabetic disorder and demonstrates its usefulness in post-mortem validation.     

Anticorruption agencies: expressive,constructivist and strategic uses

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political forces capable of continuous and consistent anticorruption effort.     

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.     

Interracial contact and fear of crime

Despite a large literature on public views about crime, the racialization of crime, and the contact hypothesis, surprisingly little is known about how interracial friendships may influence Whites’ fear of crime. At the same time, and perhaps because no counterpart stereotype to that of “Blacks as criminals” exists, there has been little exploration of how such contact may influence Blacks’ fear of crime. To address these research gaps, this study built on prior theory and research and used data from an ABC News and Washington Post poll to test competing hypotheses about the effect of interracial contact on Whites’ and Blacks’ fear of crime, respectively. The analyses revealed that close interracial friendships are associated with increased fear of crime among Whites, decreased fear of crime among lower-income Blacks, and increased fear among higher-income Blacks. The implications for theory and research are discussed.     

When (Some) Prostitution is Legal: The Impact of Law Reform on Sex Work in Australia

In Australia, prostitution regulation has taken a very different path from many other countries. Law reform has led to the opening of some significant new spaces for legal sex work, including the (very different) regulatory regimes established in two Australian states – Queensland (brothels legal if their owners are licensed) and New South Wales (most commercial sex businesses and some street prostitution decriminalized; no licensing regime). The main research question is: how has regulation impacted on the positive rights of sex workers? I argue that law reform has engaged a mix of neo-liberal and other approaches – not to increase personal or corporate freedom but as part of a practical strategy designed to control a range of social problems, such as police corruption and organized crime. Neo-liberal regulation of prostitution in Australia has always been deployed in tandem with other modes of regulation – including new criminal law and policing strategies, planning law, health regulations, and (of course) moral regulation.
