Parentage of Hydatidiform Moles

We were presented with the STR (short tandem repeat) profiles from two separate paternity trios. Each trio consisted of a mother, an alleged father, and products of conception (POC) that contained a hydatidiform mole but no visible fetus. In both cases , antecedent pregnancies had followed alleged sexual assaults. Mole classification and pathogenesis are described in order to explain the analyses and statistical reasoning used in each case. One mole exhibited several loci with two different paternal alleles, indicating it was a dispermic (heterozygous) mole. Maternal decidua contaminated the POC, preventing the identification of paternal obligate alleles (POAs) at some loci. The other mole exhibited only one paternal allele/locus at all loci and no maternal alleles, indicating it was a diandric and diploid (homozygous) mole. In each case, traditional calculations were used to determine paternity indices (PIs) at loci that exhibited one paternal allele/locus. PIs at mole loci with two different paternal alleles/locus were calculated from formulas first used for child chimeras that are always dispermic. Combined paternity indices in both mole cases strongly supported the paternity of each suspect.     

Conformity in Groups: The Effects of Others’ Views on Expressed Attitudes and Attitude Change

Two experiments demonstrate the powerful influence of others’ views on individual attitudes and attitude expression. Those around us can influence our views through persuasion and information exchange, but the current research hypothesizes that exposure to alternate views even without discussion or exchange of persuasive arguments can also alter what attitudes are expressed, and even generate long term shifts in attitudes. In an initial study, naïve participants were asked their attitudes on a range of standard survey items privately, publicly in a group with trained confederates, and again privately following the group setting. Findings indicate significant attitudinal conformity, which was most pronounced when participants were faced with a unanimous (versus non-unanimous) group. The group experience continued to influence participants’ views when they were again asked their views in private. A second experiment varied whether participants heard views from live confederates or via computer, demonstrating that these effects could not be attributed only to issue-relevant information provided by or inferred from group members, and that attitude change persisted long after participants had left the laboratory. In summary, when people are asked their attitudes publicly, they adjust their responses to conform to those around them, and this attitude change persists privately, even weeks later. Accordingly, such purely social processes of attitude change may be every bit as important as more traditional cognitive informational processes in understanding where people’s political attitudes come from, and how they may be changed.     

An Update on the Hazards and Risks of Forensic Anthropology,Part I: Human Remains

This work reviews the hazards and risks of practicing forensic anthropology in North America, with a focus on pathogens encountered through contact with unpreserved human remains. Since the publication of Galloway and Snodgrass' seminal paper concerning the hazards of forensic anthropology, research has provided new information about known pathogen hazards, and regulating authorities have updated recommendations for the recognition and treatment of several infections. Additionally, forensic anthropology has gained popularity, exposing an increased number of students and practitioners to these hazards. Current data suggest many occupational exposures to blood or body fluids go unreported, especially among students, highlighting the need for this discussion. For each pathogen and associated disease, this work addresses important history, reviews routes of exposure, provides an overview of symptoms and treatments, lists decontamination procedures, and presents data on postmortem viability. Personal protection and laboratory guidelines should be established and enforced in conjunction with the consideration of these data.     

Understanding the place of punishment: Disadvantage,politics, and the geography of imprisonment in 21st century America

Studies suggest that the spatial distribution of punishment in the United States is shifting. This article analyzes variation in prison admissions across U.S. counties to deepen our understanding of the contemporary geography of punishment. While research on punishment generally treats economic and political theories of punishment as distinct, we draw on recent studies of penal attitudes to develop a theoretical argument regarding their possible interconnection. We then use Hierarchical Linear Modeling to test the hypothesis that conservatism, race, and disadvantage are associated with the use of prison and that these factors help to explain why prison admission rates are higher in rural and suburban counties than in urban ones, despite notably higher crime rates in the latter. The results indicate that nonurban counties send more people to prison than urban counties and that socioeconomic disadvantage, the size of the Black population, and conservatism are significant predictors of prison admissions after controlling for crime‐related problems. These findings suggest that poverty, race, and politics work in concert to shape the distribution of punishment across 21st century America.     

Martyrs’ Last Letters: Are They the Same as Suicide Notes?

Abstract: Of the 800,000 suicides worldwide every year, a small number fall under Emile Durkheim’s term of altruistic suicides. Study on martyrdom has been limited. There has to date, for example, been no systematic empirical study of martyr letters. We examined 33 letters of Korean self‐immolators, compared with 33 suicide notes of a matched sample of more common suicides. An analysis of intrapsychic factors (suicide as unbearable pain, psychopathology) and interpersonal factors (suicide as murderous impulses and need to escape) revealed that, although one can use the same psychological characteristics or dynamics to understand the deaths, the state of mind of martyrs is more extreme, such that the pain is reported to be even more unbearable. Yet, there are differences, such as there was no ambivalence in the altruistic notes. It is concluded that intrapsychic and interpersonal characteristics are central in understanding martyrs, probably equal to community or societal factors. More forensic study is, however, warranted.     

Child Support and the Affordable Care Act's Medicaid Expansions

A quickly developing literature has shown that the Affordable Care Act's (ACA) Medicaid expansions have improved health insurance coverage, health, and financial well‐being among low‐income adults without dependent children. This population includes noncustodial parents. With substantial overlap in the population that is typically obligated to pay child support and the population that has strongly benefited from the expansions, there may be potential implications for child support enforcement. In this paper, I examine the effect of public health insurance eligibility to low‐income adults on child support outcomes. I find that the ACA Medicaid expansions increased child support distributed to custodial families as arrears by 8.5 percent. Evidence also suggests current support distributions increased by about 2 percent. There were no significant effects on paying toward a child support order. Among unmarried mothers, the likelihood of child support receipt increased by 8 percent. These results imply that access to public health insurance can increase the ability of noncustodial parents to pay child support.
