Nocebo Effects and Mild Traumatic Brain Injury: Legal Implications

Expectations may play a large role in health-related outcomes, but they may not be fully addressed or considered in medical–legal contexts. Contextual factors can influence a patient’s expectations for recovery following a concussion, including explicit or implicit messages from the media, healthcare providers and systems of care, and the forensic arena. This article discusses these factors as nocebo effects, that is, various inherently “inert” factors may create negative expectancies for recovery and therefore impede a given patient’s progress and recovery. It is argued that the negligence theory upon which the legal system is based tends to compound these nocebo effects. In accident-related concussions, both the accident itself and subsequent nocebo effects including potential healthcare and medical–legal provider negligence can create legal liability.     

Sexual dimorphism in human browridge volume measured from 3D models of dry crania: A new digital morphometrics approach

Sex estimation from the human skull is often a necessary step when constructing a biological profile from unidentified human remains. Traditional methods for determining the sex of a skull require observers to rank the expression of sexually dimorphic skeletal traits by subjectively assessing their qualitative differences. One of these traits is the prominence of the glabellar region above the browridge. In this paper, the volume of the browridge region was measured from digital 3D models of 128 dry crania (65 female, 63 male). The 3D models were created with a desktop laser scanner, and the browridge region of each 3D model was isolated using geometric planes defined by cranial landmarks. Statistical analysis of browridge-to-cranium volume ratios revealed significant differences between male and female crania. Differences were also observed between geographically distinct populations, and between temporally distinct populations from the same locale. The results suggest that in the future, sex determination of human crania may be assisted by quantitative computer-based volume calculations from 3D models, which can provide increased objectivity and repeatability when compared to traditional forensic techniques. The method presented in this paper can easily be extended to other volumetric regions of the human cranium.     

Current practices by forensic anthropologists in adult skeletal age estimation

When determining an age estimate from adult skeletal remains, forensic anthropologists face a series of methodological choices. These decisions, such as which skeletal region to evaluate, which methods to apply, what statistical information to use, and how to combine information from multiple methods, ultimately impacts the final reported age estimate. In this study, a questionnaire was administered to 145 forensic anthropologists, documenting current trends in adult age at death estimation procedures used throughout the field. Results indicate that the Suchey-Brooks pubic symphysis method (1990) remains the most highly favored aging technique, with cranial sutures and dental wear being the least preferred, regardless of experience. The majority of respondents stated that they vary their skeletal age estimate process case-by-case and ultimately present to officials both a narrow and broad possible age range. Overall, respondents displayed a very high degree of variation in how they generate their age estimates, and indicated that experience and expertise play a large role in skeletal age estimates.     

The role of gender in officially reported intimate partner abuse

The role of gender in intimate partner abuse (IPA) perpetration and victimization has been debated for the last several decades. Two perspectives have emerged regarding this debate. Researchers from the family violence perspective argue that men and women are violent at near equal rates and call for a reframing of the issue from one of woman battering to one of family violence. In contrast, feminist researchers maintain that men make up the majority of perpetrators and women the majority of victims in cases of intimate partner abuse. While some have put forth arguments explaining these differences, this debate is far from over. Using official reported cases of IPA, this study examines 815 IPA cases of which 13% were female perpetrated in an attempt to clarify gender differences and similarities among male and female offenders beyond prevalence rates. Special attention is paid to contextual differences and similarities and implications this research has for future research and policy.     

Youth victimization: school climate or deviant lifestyles?

Despite much focus on school violence, there has been little research that explores the relationship between offending and victimization in various school climates. School climate theory suggests that the school's social system, culture, milieu, and ecological structure affect student outcomes including academic performance, delinquency, and more recently, victimization. Hierarchical analysis of data from 5,037 11th-grade students in 33 schools found that offending behavior was the strongest predictor for both minor and more serious forms of victimization. School climate, specifically the social cohesion of schools, reduced serious violent victimization risk. However, school climate did not affect the relationship between offending and victimization, and was not substantially modified when characteristics of the school environment were considered.     

THE PROCESS OF GOVERNMENT COMMUNICATION: SOME SEMIOTIC AND CULTURAL CONSIDERATIONS

Abstract: Guidelines for government communication fail to acknowledge that they express a particular model of communication—a Process model—and that other models of communication exist which imply different communication strategies. This article discusses the practical and conceptual limitations of the Process model of communication, outlines alternative models from Semiotics and from Cultural Studies, and considers the communication strategies which each one offers to governments. The article draws on a recent study of the controversy surrounding the Australian federal government's Quality Improvement and Accreditation scheme for child care.     

Collective decision making by committee

Implicitly or explicitly, economic decisions always contain elements of compromise. However, the bargaining models of economic theory treat only the two decision maker case with linearly aggregated priorities; i.e. compromise decisions under Pareto optimality and no side payments. Even then the relative importance of the decision makers remains indeterminate. This paper proposes a simplified bargaining model with three new features: (a) it allows multiple participants; (b) it uses optimal voting patterns to combine the policy proposals, rather than the policy priorities, to form those compromise decisions; and (c) it determines the relative power of each participant endogenously. Perhaps more important, the method does not depend on each decision maker knowing the preferences of his colleagues exactly.
