Validity of the use of porcine bone in forensic cut mark studies

Porcine bone is often used as a substitute for human bone in forensic trauma studies, but little has been published on its comparative mechanical behavior. The factors affecting mechanical properties and therefore selection of bone models are complex and include the age of the animal at death, and physiological loading conditions, the latter being of particular relevance when using a quadrupedal animal as a human substitute. The regional variation in hardness of adult and infant porcine bones was investigated using Vickers’ indentation tests and compared to published data for human limb bones to relate differences to inherent genetic effects and loading influences, and to examine the validity of the porcine‐human model. Significant differences in hardness were observed both along and around the adult porcine humerus and femur, but no significant differences were found along the length of the infant bones. Significant differences were found between the forelimb and hindlimb, but only in the infant specimens. The hardness values for porcine adult cortical bone from the femur (52.23 ± 1.00 kg mm^?2) were comparable to those reported in the literature for adult human cortical bone from the fibula, ilium, and calcaneus. These data will help inform subject selection in terms of both species and bone type for use in future trauma studies.     

Fictional power and control and the reality of abusive behaviour

In response to recent sociological studies that suggest that the seriousness of psychological, emotional and verbal abuse are not only dismissed but are also the least identified in dating relationships, this article undertakes an analysis of these underexplored, ‘less visible’, elements using Ellen Pence and Michael Paymar’s ‘Power and Control’ and ‘Equality’ wheels, it compares Stephanie Meyer’s 10th anniversary re-release of Twilight, and Life and Death: Twilight Reimagined, which tells the same story as Twilight, but with the genders reversed are compared using the ‘Power and Control’ and ‘Equality’ wheels. The author argues that Life and Death is not just a simple swap of names and pronouns, as Meyer asserts, but that the alterations of thoughts and actions of the characters reflect commonly held ideas about gender, including the perpetration of psychological, emotional and verbal abuse in intimate relationships as hallmarks of masculinity. Moreover it shows that consistent with the feminisation of vampire Edythe Cullen and mortal Beau Swan, the intimate relationship in Life and Death more closely resembles that of a non-violent and equitable relationship, which significantly lessens the abuse, and reinforces traditionally socially accepted messages about gender in intimate relationships.     

Longer Term Impact of Bystander Training to Reduce Violence Acceptance and Sexism

ABSTRACT

Many bystander programs to prevent violence have been developed and evaluated in college populations. An exception is the randomized controlled trial of Green Dot, found effective in reducing violence rates and violence acceptance in 26 high-schools (2010–2014). In ‘Life’s Snapshot’, 10,727 seniors were recruited from these same schools with the goal of determining the longer-term efficacy of bystander training. Students in intervention schools could have up to three years of Green Dot exposure. Seniors from intervention versus control schools had significantly lower scores (p <.01) indicating less violence acceptance or sexism for two of five measures. Seniors’ self-reports of bystander training received confirmed these findings. These cross-sectional analyses suggest that some reductions in violence acceptance associated with bystander programming may be maintained into early adulthood.     

Smoke in the Looking Glass: Effects of Discordance Between Self- and Peer Rated Crowd Affiliation on Adolescent Anxiety, Depression and Self-feelings

Peer crowds serve as an identity marker for adolescents, indicating their image and status among peers; but adolescents do not always endorse peer appraisals of crowd affiliation. We report on two studies—one with 924 adolescents in grades 7–12 and a second with a more diverse population of 2,728 students in grades 9–11, followed for 2 years—that examined how congruence between peer and self-appraisals of crowd affiliation relate to self-esteem and internalizing symptoms. Analyses indicate that high-status crowd members may suffer and low-status crowd members benefit by denying their peer crowd affiliation, but effects are modest in size and not entirely consistent across the two studies. Findings underscore the value of symbolic interactionist principles concerning reflected appraisal processes in understanding how peer crowd affiliation affects adolescent self-image.

Community Privilege and Environmental Justice: An Agent‐Based Analysis

Several theories compete to explain observed race‐ and ethnicity‐based environmental injustice in society. This paper focuses on analyzing the extent to which firms' siting decisions based on community privilege can explain this outcome. A unique feature of this analysis is that we include analysis of both unwanted land uses (disamenity firms) and desired land uses (amenity firms). The environmental justice analysis of amenities other than green spaces is rare, but amenities are crucial components of urban areas to which environmental justice studies must attend. We use an agent‐based model to explore community outcomes when environmental disamenities choose locations based on low community privilege, and compare this with scenarios in which disamenities only seek to minimize the cost of land. We also assess differences in environmental justice outcomes when amenities choose locations in areas with high community privilege. While disamenities' focus on locating in areas with low community privilege indeed affects environmental equity, the effect of amenity location is also important, and there are powerful interaction effects. The importance of privilege‐based location is found in these simulations regardless of which social group—majority or minority—is assumed to be the privileged group. This study suggests a limitation of EJ policies and models that focus on the politics of disamenity siting without considering the politics of amenity siting.

Grappling with the “real politics” of systemic corruption: Theoretical debates versus “real‐world” functions

A growing body of research argues that anticorruption efforts fail because of a flawed theoretical foundation, where collective action theory is said to be a better lens for understanding corruption than the dominant principal–agent theory. We unpack this critique and advance several new arguments. First, the application of collective action theory to the issue of corruption has been, thus far, incomplete. Second, a collective action theory‐based approach to corruption is in fact complementary to a principal–agent approach, rather than contradictory as is claimed. Third, applications of both theories have failed to recognize that corruption persists because it functions to provide solutions to problems. We conclude by arguing that anticorruption effectiveness is difficult to achieve because it requires insights from all three perspectives—principal–agent theory, collective action theory, and corruption as serving functions—which allows us to better understand how to harness the political will needed to fight corruption.     

Liberalism and the anxiety of belief

Anxiety about perceived threats to liberal freedom has played a double role in liberalism. On the one hand, such anxiety has driven the development of liberal institutions aimed at safeguarding freedoms. Yet another, problematic, side of this anxiety can also be found in the history of liberalism and in the policies and practices of contemporary liberal states. From the beginning, liberal intolerance of those perceived to be connected, through religious affiliation or beliefs, with arbitrary or absolute power and therefore deemed to pose a threat to the existing order has justified social exclusion and, in many cases, systematic violence. Rae’s article examines the theoretical and political roots of this distinctive form of liberal anxiety, tracing the connection between anxiety about Catholicism and Catholics in John Locke’s time and contemporary anxieties about the relationship between Islamism and Muslims in liberal states.
