Investigating Investigators: Examining the Impact of Eyewitness Identification Evidence on Student-Investigators

This research examined the impact of eyewitness identification decisions on student-investigators. Undergraduates played the role of police investigators and interviewed student-witnesses who had been shown either a good or poor view of the perpetrator in a videotaped crime. Based on information obtained from the witness, student-investigators then chose a suspect from a database containing information about potential suspects and rated the probability that their suspect was the culprit. Investigators then administered a photo lineup to witnesses, and re-rated the probability that their suspect was guilty. Student-investigators were highly influenced by eyewitness identification decisions, typically overestimating the information gained from the identification decision (except under conditions that led witnesses to be very accurate), and were generally unable to differentiate between accurate and inaccurate witnesses.

Child Development and Migrant Transnationalism: The Health of Children Who Stay Behind in Ghana and Nigeria

This paper examines the relation between parental migration and children’s health in Ghana (N = 2760) and Nigeria (N = 2168) and considers four dimensions of parental migration: the type of separation, parental migration and the caregiver, stability of care arrangements, and the availability of remittances. By employing an ordered scale of children’s self-rated health, we found that children with international migrant parents who are divorced/separated are less likely than children in non-migrant families to have good health. The magnitude of the effects are higher in Nigeria, attesting for a greater vulnerability of Nigerian children in divorced migrant families. Among children with parents living abroad who are stably married, specific dimensions of children’s transnational life are associated with negative health, while others are not. This study highlights the sensitivity of results to the context of parent-child separation and to the transnational dimension being measured.     

Methamphetamine and alcohol detection in vehicle-driver fatalities in South Australia: A 10-year survey (2008–2018)

Motor vehicle driver fatalities (≥18 years) from the files at Forensic Science South Australia were reviewed from January 2008 to December 2018 for cases in which either positive blood sample for methamphetamine (MA) or an illegal blood alcohol concentration (BAC) >0.05g/100 ml were found. Three hundred driver deaths were found with MA detected in 28 cases (age range 21–62 years; ave. 37.8 years; M:F 23:5). Hundred and fifteen cases with a BAC > 0.05 g/100 ml were identified (age range 18–67 years; ave 35.7 years; M:F 95:20). No change was found in numbers of MA cases, although alcohol cases showed a significant decline (p < 0.001). Drunk driving-related fatal crashes tended to occur in the evening (5 p.m. to 11 p.m.), while MA-related fatal crashes had a longer peak extending from late evening until late morning (11 p.m. to 8 a.m.). This study has demonstrated that while roadside breath testing, legislative changes, and increased monitoring have resulted in reduced levels of drunk driving, similar safety countermeasures have had negligible effects on MA use in drivers. Continued monitoring of MA use by drivers will, therefore, be necessary to assess the possible effects, or not, of new countermeasures.     

Ideological proximity and voter turnout in multi-level systems: evidence from Spain

ABSTRACT

Does ideological proximity between the individual and political parties determine electoral participation in regional elections, as much as in national elections? Does the degree of self-rule of a region affect the interplay between ideological distance and turnout? This article addresses these questions and provides empirical evidence drawing upon individual-level and regional-level data from 53 regional elections and 4 national elections in Spain. Results indicate that citizens are more likely to vote when they perceive there is at least one congruent policy option among the party supply, and this happens at both regional and national levels. However, whether the closest party is in national government or whether it is a regionalist organization has a dissimilar impact on turnout in different tiers. This relationship between the type of party which is most ideologically proximate and electoral participation is partially affected by the degree of regional autonomy of the territory.     

How do Visitors Affect Crime?

This paper, which uses data on National Park visitors between 1979 and 1998 and every county in the United States, is the most exhaustive examination to date of how visitors affect crime. After controlling for many other factors that influence crime, the county-level regressions consistently indicate that national park visitors have no effect on either property or violent crime. These results are true for a variety of different measures of park visitors, for different empirical specifications, and for different regression formats. We therefore conclude that some visitor types have no impact on crime. This conclusion sheds light on the empirical issue of whether only some types of recreational visitors increase crime or whether visitors, regardless of their type, necessarily increase crime.     

Sexual Revictimization Among College Women: A Review Through an Ecological Lens

This paper reviews factors at the individual, microsystem, meso/exosystem, and macrosystem levels that contribute to sexual revictimization among college women. Potential implications for reducing sexual revictimization on campuses via multilevel targeting of interventions is then discussed. This review reveals that despite a need for additional work examining the influence of multiple interacting factors contributing to revictimization, extant work offers insights as to how colleges can develop comprehensive programs to reduce sexual revictimization. Such programming would not only improve institutional responses to sexual violence, but also serve as a model for reducing general cultural acceptance of the perpetration of sexual assault.     

Shells and Bones: A Forensic Medicine Study of the Association of Terrestrial Snail Allopeas micra with Buried Human Remains in Brazil

Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case.
