Development of a Mobile Toolmark Characterization/Comparison System

Since the development of the striagraph, various attempts have been made to enhance forensic investigation through the use of measuring and imaging equipment. This study describes the development of a prototype system employing an easy‐to‐use software interface designed to provide forensic examiners with the ability to measure topography of a toolmarked surface and then conduct various comparisons using a statistical algorithm. Acquisition of the data is carried out using a portable 3D optical profilometer, and comparison of the resulting data files is made using software named “MANTIS” (Mark and Tool Inspection Suite). The system has been tested on laboratory‐produced markings that include fully striated marks (e.g., screwdriver markings), quasistriated markings produced by shear‐cut pliers, impression marks left by chisels, rifling marks on bullets, and cut marks produced by knives. Using the system, an examiner has the potential to (i) visually compare two toolmarked surfaces in a manner similar to a comparison microscope and (ii) use the quantitative information embedded within the acquired data to obtain an objective statistical comparison of the data files. This study shows that, based on the results from laboratory samples, the system has great potential for aiding examiners in conducting comparisons of toolmarks.     

Criminological theory in the digital age: The case of social learning theory and digital piracy

To date, few studies had attempted to extend existing theories of crime to technology driven crimes, such as digital piracy. To address this gap in the literature, this study explored the ability of Akers’ social learning theory in explaining the likelihood of engaging in digital piracy. Also explored was the extent to which the social learning process mediated the impact of several noteworthy correlates of digital piracy among college students attending different universities (n = 585), relying on a structural equation modeling (SEM) framework. The findings were modestly supportive of social learning theory as it may apply to digital piracy. The findings are discussed in the context of extending existing theories of crime to account for contemporary technology driven crimes, such as digital piracy. Policy implications and direction for future research are discussed.     

Female student athletes’ perceptions of acceptability and the occurrence of sexual-related behaviour by their coaches in India

The current study assessed the perceptions of acceptable sexual behaviour of coaches and the occurrence of sexual harassment among female student in India. A sample of 180 Indian female student-athletes at intercollegiate and inter-university levels with male coaches participated in this study. A questionnaire on sport-specific Touch and Behaviour versus Unwanted Intimacy from coaches (Vanden Auweele et al., 2008), consisting of 41 items on a 5-point rating scale was used. The participants were asked to indicate the acceptability of specific coaching behaviour as well as the occurrence of the behaviour represented in each item. The acceptability of the behaviour was determined by means and standard deviations, while the occurrence was determined by frequencies. Factor analysis was performed to determine the structure of the coaches’ behaviour and athletes’ acceptability thereof, which yielded four factors. Cronbach’s alpha was used to determine the internal consistency of the extracted items on each factor. Two factors, namely, unwanted sexual behaviour and inappropriate verbal and physical sexual behaviour, were regarded by athletes as very serious and unacceptable coach behaviour, while a third factor represented context-dependent suspicious behaviour (a grey area in which athletes differ in their opinion) and was perceived to be serious and unacceptable. A fourth factor represented acceptable behaviour. The occurrence of very serious and unacceptable behaviour was reported by 31% of the female athletes.     

Welfare Reform, Mississippi Style: Temporary Assistance for Needy Families and the Search for Accountability

Through an examination of the implementation of the 1996 Personal Responsibility and Work Opportunity Act in the state of Mississippi, we explore the adequacy of traditional two-actor principal-agent theory. Using this as our lens, we suggest that the choices made by Mississippi in the area of welfare reform to privatize much of the work and to add several layers to the existing principal-agent relationship substantially reduced accountability and the effectiveness of the monitoring systems. We conclude that not only is traditional principal-agent theory an insufficient tool for understanding the complex interrelationship between democratic actors in this particular case, the decisions of the state of Mississippi to complicate the principal-actor relationship through privatization also undermined the reform effort itself in ways that may have general implications for other like-minded efforts in other policy areas.
