A Pimp's Game: A Rational Choice Approach to Understanding the Decisions of Sex Traffickers

We employ a rational choice framework to understand the conditions under which sex traffickers allow their victims access to telecommunications devices while under their control. We posit that sex traffickers are rational actors who make calculated decisions regarding whether to allow their victims access to the Internet and cell phones. We hypothesize that sex traffickers allow younger victims and those they did not defraud in the recruitment process greater access to telecommunications devices because these decisions maximize their payoffs with minimal risk. However, we hypothesize that younger victims’ access to telecommunications devices is conditional on whether they have been defrauded in recruitment. In order to test these hypotheses, we deployed a survey to 115 victims of sex trafficking in the United States to learn about how they were recruited by their sex trafficker and the level of access they had to technology while under their sex trafficker's control. We find support for all of our hypotheses. The results have serious implications for criminal justice policy and practice.     

Russia's Artificial Intelligence Strategy: The Role of State-Owned Firms

In 2017, Russian President Vladimir Putin declared that whichever country becomes the leader in artificial intelligence (AI) “will become the ruler of the world.” Yet Russia lags competitors like China and the United States substantially in AI capabilities. What is Russia's strategy for boosting development of AI technologies, and what role do groups within the Russian elite play in shaping this strategy? Russia's AI development strategy is unique in that it is led not by the government, nor by the private sector, but by state-owned firms. The government's distrust of Russia's largest tech firm, Yandex, has sidelined the company from national AI planning. Meanwhile, Russia's defense conglomerate Rostec publicly appears to focus less on artificial intelligence than on other high-tech priorities. As a result, Russia's AI development has been left to a state-owned bank, Sberbank, which has taken the lead in devising plans for government-backed investment in AI.     

Evaluation of vapor profiles of explosives over time using ATASS (Automated Training Aid Simulation using SPME)

Despite numerous instrumental achievements, canines are still considered the most effective field method for explosive detection. However, due to strict explosive regulations and safety requirements, it can be a challenge for agencies with "bomb dogs" to train using neat explosive materials. This establishes a need for non-explosive canine training aids with the same volatile component profiles as the explosives that they represent. In order to compare mimic materials to their explosive counterparts, a technique must be established that not only allows for identification of volatile compounds but also can monitor changes in the headspace profile over time with respect to time and temperature. The Automated Training Aid Simulation using SPME (or ATASS) was developed for that purpose. As described, ATASS was used to observe changes in the volatile profile of three explosives (Composition C-4, 2,4-dinitrotoluene (DNT), and triacetone triperoxide (TATP)) and respective prototype training materials (0.1% by mass C-4, 1% by mass 2,4-DNT, and 1% by mass TATP). Samples were prepared in vials and metal tins within a gallon (≈ 3785 mL) paint can to simulate common field techniques for canine training. Monitoring these materials in real time provides a better understanding of the major volatile components present and how the relative abundances of these components can change over time. The results presented indicate that ATASS successfully allows for a sufficient comparison between explosive and non-explosive training materials.     

When Citizens Fight Back: Justice Sensitivity and Resistance to Political Reform

A considerable number of individuals show resistance to reform, whereas others, although similarly affected, do not react in a resistant way at all. Based on research showing that people differ concerning how sensitive they are toward being a victim of injustice (victim justice sensitivity), we argued that people high in victim justice sensitivity perceive a reform more as an illegitimate limitation to their freedom resulting in more reactance. Consequently, people high in victim justice sensitivity should show more resistance to reform. We conducted three studies to test these assumptions. Our studies revealed that physicians (healthcare reform, Study 1) and students (introduction of tuition fees, Studies 2 and 3) with higher victim justice sensitivity experienced more reactance and thus showed more resistance to reform. The implications of these results for the implementation of political reforms are discussed.     

The counselor's trauma as counseling motivation: vulnerability or stress inoculation?

Should counselors with interpersonal trauma histories work with similarly traumatized clients? How does the work affect them? Current research is inconsistent. This study examines 101 sexual assault and domestic violence counselors' recalled motivations for trauma work, their reported subjective personal changes, and their secondary and vicarious trauma symptoms and burnout. Counselors motivated by interpersonal trauma report both more symptoms and positive changes (including dealing with their own trauma). Those seeking personal meaning report becoming more hypervigilant and self-isolating. Those saying they learned from clients rate symptoms lower, suggesting stress inoculation. Supervisors of trauma counselors should facilitate learning from clients separately from processing the counselor's trauma.     

A Commentary on the MND Model and the Boone Critique: “Saying It Doesn’t Make It So”

We appreciate Boone’s (2011, this issue) critique of Rogers, Bender, and Johnson’s (2011, this issue) analysis of the Malingered Neurocognitive Dysfunction (MND) criteria. She raised good points and appeared in general agreement regarding several crucial limitations of the MND model. However, Boone remained mostly silent on several issues including the compelling results from our methodological review of MND studies and Criteria A through D. When provided, her comments tended to be very selective and were often presented with little or no empirical support. This contrasting pattern of strong statements and weak evidence appears to unintentionally parallel the MND model, which was documented in our original analysis. As a result of her criticism, however, we clarified our point regarding methodological limitations in establishing levels of TBI and its potential relevance to determinations of feigned cognitive impairment. We hope that these spirited discussions will stimulate a much-needed review and a fundamental revamping, if not replacement, of the MND model.     

Taphonomic changes to blunt force trauma: a preliminary study

This study examines the effects of taphonomic processes on blunt force trauma (BFT) through an experimental study involving pig heads. Of particular concern is the possibility that taphonomic changes can create pseudo-trauma and/or conceal evidence of actual trauma. BFT was inflicted on 10 pig skulls using a hammer. The skulls were subsequently exposed to the environment for 12 months. Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining. Taphonomic effects varied between cancellous, compact, fresh, and degreased bone. Freezing and thawing, exposure to rain and snow, movement of the skulls, and soil erosion altered and, in some cases disguised, pre-existing trauma. Rodent and carnivore activity did not obliterate evidence of BFT. Recommendations for evaluating BFT on remains affected by taphonomic processes are presented. As each taphonomic process outlined by this study has the potential to disguise antemortem injury, the authors propose that one must carefully examine large, circular openings in the skull that may represent the remnant evidence of BFT.     

Assessment of Silicone Polymer Composites for Environmental Forensic Applications: A Proof of Concept Study*

Abstract: This study evaluates the use of polydimethylsiloxane polymer composites (PDMS, Fe–PDMS) as a passive sampling media to preconcentrate analytes found in environmental settings. Samplers were made using commercially available silicone products. The composite samplers were assessed for their sorption properties using Atrazine and Irgarol 1051 as model compounds. The initial study assessed the utility of PDMS sheets as adsorption material by following analyte depletion from spiked water samples by solid‐phase microextraction gas chromatography/mass spectrometry (GC/MS). Follow‐up studies conducted at high and low concentrations using lab manufactured iron‐ PDMS rods (Fe–PDMS) showed effective uptake at differential rates from concentrations ranging between 1 μg/L and 10 μg/L. Adsorption mechanism was reversible, and compounds were recovered from the exposed materials and analyzed by liquid–liquid extraction‐GC/MS. Both composites showed better affinity for Irgarol 1051, 100% removal, than for Atrazine, 30% removal, likely representing their K_OW differences, 3.6 and 2.6, respectively. This “proof of concept” study demonstrates the positive implications for the use of silicon polymer composites as a monitoring tool for environmental forensic purposes.     

Between the ‘Home’ and ‘Institutional’ Worlds: Tensions and Contradictions in the Practice of House Arrest

In this paper we argue that the theoretical work of Goffman (1961) on “total institutions,” Foucault’s (1977) insights into the workings of disciplinary power, and an account of contemporary forms of punishment and social control in postmodern society (Staples 2000) help us better understand the experiences of those individuals sentenced to house arrest. Based on face-to-face interviews with twenty-three people being electronically monitored in a Midwestern metropolitan area, our analysis identifies three themes that illustrate the ways in which electronic monitoring is experienced as a complex amalgam of what Goffman (1961, p. 13) saw as the distinct “home world” and the “institutional world”. These themes include (1) “Home is Where the Machine Is,” (2) “Producing Docile Bodies,” and (3) “Threat of Sanctions”. We reassert our claim (Staples 1994, 2000) that contemporary forms of social control such as electronic monitoring reflect an ongoing struggle to deal with problems and issues set in motion with the birth of modernity.     

Cranial Backspatter Pattern Production Utilizing Human Cadavers

A backspatter pattern results from blood drops that travel retrograde to an applied external force. Historically, an array of animals and nonhuman objects have been used to create and study backspatter patterns. In this study, backspatter patterns captured on foam core targets that were placed 45.72 cm (18 in) behind the impact site (occipital area of the skull) were produced by cranial gunshots to human cadavers that were reinfused with fresh defibrinated bovine blood. These patterns were compared to the backspatter patterns produced by shooting blood‐soaked sponges, a typical simulant used in controlled studies of backspatter pattern production and characteristics. The backspatter pattern produced by shooting an actual human head was found to be different than those of blood‐soaked sponges in the number of stains produced, the size and size range of the stains, and the stain dispersion patterns.
