Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology

There are specific challenges related to forensic dental radiology and difficulties in aligning X‐ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X‐ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors. Each participant exposed six X‐rays per device for a total of 432 X‐rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax—both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed.     

Taphonomic Effects of Mechanical Plowing on Buried Juvenile‐Sized Remains

Agricultural activity is a worldwide taphonomic process and can present unique challenges in the recovery of buried remains. Previous research has been mostly within the realm of site formation processes of archeological sites utilizing only surface material. This research expands upon the previous research by incorporating the distribution of subsurface material by the use of archeological excavation techniques. An experiment was conducted utilizing juvenile pig (Sus scrofa) skeletons buried in relative anatomical position at two different depths (15 cm below the surface [cmbs] and 22 cmbs). The burials were then subjected to different intervals of mechanical plowing: one, three, five, seven, or 10 plow passes. The skeletal material was recovered using pedestrian survey followed by hand excavation and screening of all sediments. This research shows that there is a significant relationship between the degree of plowing and the distance skeletal material is distributed and the percentage of material recovered undamaged.     

Participation in prevention programs for dating violence: beliefs about relationship violence and intention to participate

This study utilizes the Health Belief Model (HBM) to examine the factors related to the intention to participate in prevention programming for dating violence. Perceptions of susceptibility to future violence and the benefits of prevention programming appear to be the strongest predictors of participation in prevention programs. Perceptions of the severity of dating violence do not appear to be related to intentions to participate. There were no differences in intention between those reporting psychological or physical violence in their dating relationship, although some of the HBM factors were associated with a history of violence. Contrary to hypotheses, psychological and physical violence did not moderate the impact of the HBM factors on intention. Implications of these findings are discussed and recommendations for recruiting participants for primary and secondary prevention programs are offered.     

Associations Between Police Work Stressors and Posttraumatic Stress Disorder Symptoms: Examining the Moderating Effects of Coping

The role of coping in the association between stress and posttraumatic stress disorder (PTSD) is not clear. We investigated the effects of active and passive coping strategies on the associations between police stress (administrative and organization pressure, physical and psychological threats, and lack of support) and PTSD symptoms in 342 police officers. Linear regression model was used in the analyses. The association between physical and psychological stress and PTSD symptoms was stronger in officers who used lower active coping (B?=?4.34, p?<?0.001) compared to those who utilized higher active coping (p_-interaction?=?0.027) (B?=?1.79, p?≤?0.003). A similar result was found between lack of support and PTSD symptoms (p_-interaction?=?0.016) (lower active coping, B?=?5.70, p?<?0.001; higher active coping, B?=?3.33, p?<?0.001), but was not significantly different comparing the two groups regarding the association between administrative and organizational pressure and PTSD symptoms (p_-interaction?=?0.376). Associations of total stress, administrative and organizational pressure, and physical and psychological stressors with PTSD symptoms were significantly stronger in officers who utilized higher passive coping (p_-interaction?=?0.011, 0.030, and 0.023, respectively). In conclusion, low active or high passive coping methods may exacerbate the effect of work stress on PTSD symptoms.     

Racial Bias in Mock Juror Decision-Making: A Meta-Analytic Review of Defendant Treatment

Common wisdom seems to suggest that racial bias, defined as disparate treatment of minority defendants, exists in jury decision-making, with Black defendants being treated more harshly by jurors than White defendants. The empirical research, however, is inconsistent—some studies show racial bias while others do not. Two previous meta-analyses have found conflicting results regarding the existence of racial bias in juror decision-making (Mazzella & Feingold, 1994, Journal of Applied Social Psychology, 24, 1315–1344; Sweeney & Haney, 1992, Behavioral Sciences and the Law, 10, 179–195). This research takes a meta-analytic approach to further investigate the inconsistencies within the empirical literature on racial bias in juror decision-making by defining racial bias as disparate treatment of racial out-groups (rather than focusing upon the minority group alone). Our results suggest that a small, yet significant, effect of racial bias in decision-making is present across studies, but that the effect becomes more pronounced when certain moderators are considered. The state of the research will be discussed in light of these findings.     

Y-chromosome STR haplotype diversity in Brazilian populations

A sample of 198 unrelated males distributed among the five geopolitical regions in Brazil were typed for the minimal Y-STR haplotype composed of microsatellite loci DYS19, DYS385I/II, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393. Gene frequency data, gene diversity, haplotype diversity and power of discrimination were estimated. An AMOVA indicated that 99.97% of the haplotypic variation is found within regions and only a small 0.03% and non significant variation is found among the five regions (Fst=0.00031, P-value=0.43). This result suggests that a single national database of Y-STR haplotypes can be used in the quantitative assessment of matches in forensic casework in the Brazilian population. A significant haplotype diversity of 99.8% was found and 172 different haplotypes were observed in 198 chromosomes. Haplotype (14-11, 14-13-29-24-11-13-13) with five occurrences in 198 chromosomes was the most frequent in Brazil.     

The scent of a green carnation: A review of the queer year

The “Blitz spirit” is a popular story about the British public during the Second World War, uniting together with defiance and resilience to overcome the threat of invasion from Nazi Germany. Previous work has revised this wartime story as a propagandistic construction of national identity and popular memory. Therefore, this paper reviews the Blitz spirit as a myth. A critical discourse analysis (CDA) then examines how this myth was retold in British newspapers after the July 7th bombings in London. I examine how this myth was constructed and the ideological role it played after the attacks. Similar to previous revisions of the Blitz myth from 1940, I argue that social and political complexities after July 7th were often suppressed by messages that sought to evoke a sense of “Britishness” defined by a previous generation. Whilst the July 7th bombings were not a case of traditional warfare or attacks carried out by a foreign force, I argue that wartime analogies often supported military responses in the war on terror and evoked a foreign threat.     

Judges as therapists and therapists as judges: the collision of judicial and therapeutic roles in drug treatment courts

This paper explores the implications of the expansion of judicial and therapeutic roles in a drug treatment court (DTC) in Canada. Issues that are raised are: how the courtroom is framed as a therapeutic space where public appearances by participants are part of the therapeutic process; how judges have taken on therapeutic practices, effectively compromising their traditional role as neutral arbiter; how certain women resisted therapeutic interventions by judges and felt they received harsher punishments than men; and how treatment counselors in DTCs are given powers of enforcement over their clients. The collision of judicial and therapeutic roles in the DTC results in negative consequences for individuals in the specialized courts. Specifically, DTC participants are expected to engage in a therapeutic relationship with their treatment counselors and the court; however, their right to confidentiality is withheld, and their treatment counselors act as agents for the court.
