A Radiographic Study on the Utility of Cranial Vault Outlines for Positive Identifications

A standard method for positive identification is the use of antemortem and postmortem radiographic comparisons. The purpose of this research is to test the visual accuracy of antemortem and postmortem radiographic comparisons of cranial vault outlines and to evaluate their uniqueness using geometric morphometric methods. A sample of 106 individuals with varying levels of education and forensic case experience participated in a visual accuracy test. Of the 106 individuals, only 42% correctly assigned all of the radiographs, with accuracy rates ranging from 70 to 93% for each radiographic comparison. Vault shape was further examined using elliptic Fourier analysis, and paired t‐tests were computed on the first 10 principal components accounting for 100% of the variance, which found no significant differences. The visual accuracy test and elliptic Fourier analysis shows that vault outlines may not be unique enough for positive identifications when used as a sole indicator.     

Sexual crime and place: The impact of the environmental context on sexual assault outcomes

Purpose

Using the rational choice perspective, the current study investigates the impact that the environment and offending behavior have on serial sexual crime event outcomes.

Methods

The effects of time and place factors, as well as offender modus operandi strategies, on sexual crime event outcomes are tested using Generalized Estimating Equations on a sample of 361 crime events committed by 72 serial sex offenders.

Results

Time and place do impact serial stranger sexual offenders’ modus operandi strategies, but the place characteristics of the crime have more of an effect on the offender’s behavior than do the temporal conditions during which the event occurs. Subsequent analyses indicate that temporal and place factors, as well as offender modus operandi strategies, predict whether the offender completes the rape, his reaction to victim resistance, and the level of physical force that he inflicts on the victim, but not whether the victim is forced to commit sexual acts on the offender.

Conclusions

Serial stranger sexual offenders are effective decision-makers who adapt their strategies to the physical environment in which they commit their crimes, but their degree of rationality can vary as some outcomes are more dependent on the context than the offender and his actions.     

Crime Scene Staging in Homicide

A nonrandom national U.S. sample of 946 homicide crime scenes--supplied by the FBI Behavioral Science Unit for purposes of research--was studied to delineate the prevalence, types, levels, and motives for staging in domestic, nonserial sexual, serial sexual, and general felony homicides. Stagers were found to be a relatively small group who employ a variety of methods to alter the crime scene in an attempt to redirect the investigation away from themselves as logical suspects. Results also suggest that different types of homicides have different staging rates based primarily on the relationship (or connection) between offender and victim. Implications for investigations and understanding this type of crime scene behavior are discussed.     

Use of laser-scanning confocal microscopy in the detection of diagenesis in bone

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM.     

From Rebels to Rulers: The Challenges of Transition for Non-state Armed Groups in Mindanao and Myanmar

This article presents a critical comparison of the ongoing peace processes in the southern Philippines and Myanmar (Burma). It does so by examining two key armed groups: the Moro Islamic Liberation Front (MILF) on Mindanao, and the Karen National Union (KNU) in Myanmar. We identify common elements that help to explain the relative – albeit incomplete – success of these two groups in navigating their respective peace processes. The MILF and KNU are ethnonationalist armed groups struggling for self-determination against states that are experienced by ethnic minority communities as culturally alien, and economically and politically dominant. Both conflict actors are characterized by complex combinations of “greed” and “grievance” factors but nevertheless enjoy significant (albeit contested) political legitimacy among the communities they seek to represent. We explore the complex relationships between armed ethnic groups, conflict-affected communities, and civil society actors. We argue that engagement with civil society is a key element of success in the Mindanao peace process, which could be replicated in Myanmar. We examine the roles and changing nature of the state in the Philippines and Myanmar, and contrast the degrees of international involvement, as key variables in these peace processes. We observe that negotiations of comprehensive peace settlements are threatened by “the tyranny of elections” in Myanmar (2015) and the Philippines (2016), and observe the importance of including national parliaments in peace processes in a timely manner. The peace process between Manila and the MILF represents a rare example of a Muslim minority pursuing its political objectives through structured dialogue. The article focuses on the challenges faced by armed groups moving from insurgency to reinvent themselves as credible political actors and governance authorities. Our analysis draws on peace-building literature, specifically the phenomenon of “rebel governance.”

Trust in the Police in Rural China: a Comparison Between Villagers and Local Officials

Although the past decade has witnessed the rise of studies on Chinese evaluations of the police, rural villagers’ assessments of the police remain under-researched. Drawing upon performance theory and survey data from China’s countryside, this study tested whether variations in satisfaction with government performance and life are linked to villagers’ and officials’ trust in county and local/town police. We found that villagers displayed lower levels of trust in the police than local officials. Higher satisfaction with government performance and integrity were associated with greater trust in county police among both villagers and officials. Villagers’ greater satisfaction with crime control and safety led to their stronger trust in both county and town police, but such satisfaction was not significantly related to officials’ trust in both levels of police forces. Rural residents’ generalized trust and particularized trust were associated with a greater likelihood of viewing the police as trustworthy. Meanwhile, female respondents, both villagers and officials, and higher-income officials were more likely to view the police as trustworthy. Directions for future research and policy are discussed.

     

Undocumented Border Crosser Deaths in Arizona: Expanding Intrastate Collaborative Efforts in Identification

Undocumented Border Crosser (UBC) deaths in Arizona are a major issue faced by medicolegal authorities. Currently, the Maricopa County Office of the Medical Examiner (MCOME) is in possession of over two hundred unidentified individuals, more than half of whom are presumed to be UBCs. The primary goal of this study was to address the growing number of UBC deaths in Maricopa County in order to provide a more comprehensive picture of this important anthropological issue within the state of Arizona. Of the 107 total UBC cases evaluated for the study, the majority were male and age estimates for all individuals were between 15 to 60 years old. Modeled after the recording system established by the Pima County Office of the Medical Examiner, the biographic and geographic data for these cases were entered into a new UBC database at MCOME and later added to the online Map of Migrant Mortality.     

The price of personalizing politics: Political distrust and economic performance in Latin America, 1996–2006

While research has provided evidence that culture and institutional performance shape individual level trust in political institutions, scholars have neglected to adequately estimate the effect of political institutions and macroeconomic conditions on trust. Using data from the World Value Surveys for eleven Latin American cases, we test if countries with “partyizing” electoral systems - those with rules that encourage voters to hold the party, not individuals, accountable for government performance - experience lower levels of distrust in political parties and the legislature in times of poor economic conditions than those countries with “personalizing” electoral rules. Our analysis shows that the macro political and economic context largely conditions the impact of culture and institutional performance on political trust.     

Depressive symptoms among working women in rural North Carolina: a comparison of women in poultry processing and other low-wage jobs

We report on the prevalence of self-reported depressive symptoms and associated factors among women employed in a poultry processing plant and a community comparison group of other employed women in northeastern North Carolina in the southern United States. The rural area is poor and sparsely populated with an African American majority. The largest employer of women in the area is a poultry processing plant. The goals of the analyses were 1) to evaluate whether women employed in poultry processing had a higher prevalence of depressive symptoms than other working women from the same geographic area, and 2) to evaluate factors which might be associated with depression among all of these working women, including specific characteristics of their work environment. Recruitment of participants (n=590) and data collection were by community-based staff who were also African American women. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D). Work organization factors were measured with the Job Content Questionnaire (JCQ). Log-binomial regression was used to calculate crude and adjusted prevalence ratios. The prevalence of depressive symptoms, based on a CES-D measure of sixteen or more, was 47.8% among the poultry workers and 19.7% among the other working women (prevalence ratio=2.3). After adjusting for socioeconomic variables, health-related quality of life and coping style, the prevalence of depressive symptoms remained 80% higher among the poultry workers. The prevalence of symptoms was also higher among those who perceived low social support at work, hazardous work conditions, job insecurity, and high levels of isometric load. These factors were all more common among the women employed in the poultry plant. The concentration of this low-wage industry in economically depressed rural areas illuminates how class exploitation and racial discrimination may influence disparities in health among working women.
