Metric forensic anthropology decisions: Reliability and biasability of sectioning-point-based sex estimates

Subjective decisions make human cognitive processes more susceptible to bias and error. Specifically, research indicates that additional context biases forensic anthropologists’ morphological analyses. To address whether metric analyses are also subject to bias, we conducted a pilot study in which 52 experienced osteologists measured a difficult-to-classify human femur, with or without additional contextual information. Using a metric sectioning-point sex-estimation method, participants provided a sex estimate for individual skeletal element(s) and, when given multiple elements, the combined skeletal assemblage. Control group participants (n = 24) measured only the femur. In addition to the femur, bias group participants (n = 28) either measured a female humerus and viewed a female-biasing photograph (n = 14) or measured a male humerus and viewed a male-biasing photograph (n = 14). We explored whether the experts in the different groups would differ in: (1) femoral measurements; (2) femoral sex-estimation conclusions; and (3) final sex-estimation conclusions for the skeletal assemblage. Although the femoral measurements and femoral sex estimates were comparable across groups, the overall sex estimates in the female-biased group were impacted by contextual information—differing from both the control and male-biased groups (p < 0.001). Our results demonstrate that cognitive bias can occur even in metric sex-estimation conclusions. Specifically, this occurred when the metric data and single-element sex estimates were synthesized into an overall estimate. Thus, our results suggest that metric methods are most vulnerable to bias when data are synthesized into an overall conclusion, highlighting the need for bias countermeasures and comprehensive statistical frameworks for synthesizing metric data to mitigate the effects of cognitive bias.     

The politics of mortgage credit expansion in the small coordinated market economies

Abstract

Recent contributions to the comparative political economy literature claim that liberal market economies are vulnerable to asset booms and busts because of financial deregulation, shrinking welfare states and a political ideology emphasising financial self-sufficiency. This article examines the rapid expansion of mortgage lending in three coordinated market economies (CMEs): Denmark, Sweden and the Netherlands. This expansion is puzzling given that all three countries are CMEs with generous welfare states. Yet the pattern of mortgage lending resembles the Anglo-Saxon or liberal market economies (LMEs) more than other CMEs. The article argues that mortgage bubbles in the small CMEs emerged as the unintended outcome of pairing neoliberal programmes to expand home ownership with collectivist housing institutions. This resulted in supply restrictions and rising property values which saddled households with extraordinarily high mortgage debts. In short, mortgage credit bubbles are not unique to Anglo-liberal welfare states and may have different origins.     

Defense Industries and Global Dependency

The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal.     

Consequences and dilemmas in therapeutic relationships with families resulting from mandatory reporting legislation

Mandatory reporting legislation has been adopted in every state to insure the protection of children from maltreatment. These statutes have become a significant factor in the lives of mental health professionals who work with children and families. Thirty psychotherapists who had made a recent report of child maltreatment on a client in treatment were interviewed about their experiences with reporting and the consequences of reporting for therapeutic relationships. Several potentially problematic consequences and dilemmas were identified by the therapists, including immediate and long-term effects on the therapeutic alliance and course of therapy, and conflicts of interest in working with children and families.     

Genetic markers in human bone: I. Deoxyribonucleic acid (DNA) analysis.

Deoxyribonucleic acid (DNA) was isolated from a number of spongy and compact human bone tissue specimens, and the yield was estimated on a "per milligram of starting tissue" basis. DNA was, in addition, isolated from a number of corresponding blood and bone tissue specimens. Spectrophotofluorometry and ethidium bromide visualization on minigels were used to estimate the quantity and degree of degradation of DNA. The DNA from several blood-bone pairs is shown to give concordant restriction fragment length polymorphism (RFLP) typing results by two different typing protocols with five different single-locus probes. DNA from several additional blood-bone pairs is shown to give concordant results for human leucocyte antigen (HLA)-DQ alpha phenotypes following polymerase chain reaction (PCR) amplification and hybridization to specific allele-specific oligonucleotide (ASO) probes, and for the variable numbers of tandem repeats (VNTR) length polymorphisms 3' to the human apolipoprotein B (APOB) gene following PCR amplification with specific primers and analysis of the products by electrophoresis and ethidium bromide visualization.
