Sexual dimorphism in America: geometric morphometric analysis of the craniofacial region

One of the four pillars of the anthropological protocol is the estimation of sex. The protocol generally consists of linear metric analysis or visually assessing individual skeletal traits on the skull and pelvis based on an ordinal scale of 1-5, ranging from very masculine to very feminine. The morphologic traits are then some how averaged by the investigator to estimate sex. Some skulls may be misclassified because of apparent morphologic features that appear more or less robust due to size differences among individuals. The question of misclassification may be further exemplified in light of comparisons across populations that may differ not only in cranial robusticity but also in stature and general physique. The purpose of this study is to further examine the effect of size and sex on craniofacial shape among American populations to better understand the allometric foundation of skeletal traits currently used for sex estimation. Three-dimensional coordinates of 16 standard craniofacial landmarks were collected using a Microscribe-3DX digitizer. Data were collected for 118 American White and Black males and females from the W.M. Bass Donated Collection and the Forensic Data Bank. The MANCOVA procedure tested shape differences as a function of sex and size. Sex had a significant influence on shape for both American Whites (F = 2.90; d.f. = 19, 39; p > F = 0.0024) and Blacks (F = 2.81; d.f. = 19, 37; p > F = 0.0035), whereas size did not have a significant influence on shape in either Whites (F = 1.69; d.f. = 19, 39; p > F = 0.08) or Blacks (F = 1.09; d.f. = 19, 37; p > F = 0.40). Therefore, for each sex, individuals of various sizes were statistically the same shape. In other words, while significant differences were present between the size of males and females (males on average were larger), there was no size effect beyond that accounted for by sex differences in size. Moreover, the consistency between American groups is interesting as it suggests that population differences in sexual dimorphism may result more from human variation in size than allometric variation in craniofacial morphology.     

The Nature of Circuit Court Gatekeeping Decisions

This article provides an analysis of the nature of circuit court threshold decisions. Specifically, a model sensitive to the institutional context of the circuits is developed and tested across all threshold decisions in the sample and in more limited samples of proper party and proper forum votes. The results suggest that circuit court gatekeeping is a function of multiple factors, including circuit court law, litigant status, the lower court decision, and, at times, the ideological preferences of the circuit judge or that of his or her circuit.     

from pillar to post: understanding the victimisation of women and children who experience domestic violence in an age of austerity

The dismantling of the welfare state across the United Kingdom (and indeed a number of other Western industrialised democracies, such as Canada and the United States) and the reductions to welfare provisions and entitlements are having a detrimental impact on women’s equality and safety. Towers and Walby argue that the recent cuts to welfare provision in the United Kingdom, particularly for women’s services, could lead to increased levels of violence for women and girls. This paper makes the argument that female victims of domestic abuse experience violence on two levels: first, at the intimate/personal level through their relationship with an abuser and, second, at a structural level, through the state failing to provide adequate protection and provision for women who have experienced violence in intimate relationships. Using a specific example of post-violence community services delivered to both the children of women who have experienced domestic violence and the women themselves, this paper draws on empirical research carried out in 2010–2011 with London-based third-sector and public sector organisations delivering the Against Violence and Abuse Project ‘Community Group Programme’. We argue that the lack of services for women involved in, or exiting, a violent relationship can amount to state-sanctioned violence, if funding is withheld, or indeed, stretched to breaking point.     

Sectarian Framing in the Syrian Civil War

How do civilians respond to civil war narratives? Do they react to ethnic frames more strongly than to alternatives? Governments and rebels battle for hearts and minds as well as strategic terrain, and winning the narrative war can shift legitimacy, popular support, and material resources to the sympathetically framed side. We examine the effect of one‐sided and competing war discourses on ordinary people's understandings of the Syrian civil war—a conflict with multiple narratives, but which has become more communal over time. We conduct a framing experiment with a representative sample of Syrian refugees in Lebanon in which we vary the narrative that describes the reasons for the conflict. We find that sectarian explanations, framed in isolation, strongly increase the importance government supporters place on fighting. When counterframed against competing narratives, however, the rallying effect of sectarianism drops and vanishes.     

Navigating the Unknown: Barriers to Evidence-Based Defence and Security Policy in the European Union

At a time when Europe faces numerous crises, there is a real need for rigorous evidence to underpin effective policymaking. However, a gap between academia and policy creates clear obstacles in the use of evidence in policymaking. Many of these enduring obstacles are manifest in the inherent differences between separate communities: academics have difficulty communicating research in an applicable manner, and policymakers, in turn, tend to focus on operational motivations. The gap widens considerably when foreign, security and defence policy within the complex institutional structures of the European Union is considered. In addition to these well known barriers to evidence-based policy, there are two more obstacles in the defence and security space: sovereignty and dispersed decision-making. A dialogue of best practices must be opened up to broker knowledge in the EU context.     

Integrating Public Deliberation into Engineering Systems: Participatory Technology Assessment of NASA’s Asteroid Redirect Mission

We discuss an experiment employing participatory technology assessment (pTA), a public deliberation method for eliciting lay citizen input prior to making decisions about science and technology to inform upstream engineering decisions concerning technical aspects of NASA’s Asteroid Initiative. In partnership with NASA, the Expert and Citizen Assessment of Science and Technology network conducted a pTA forum on NASA’s Asteroid Initiative in 2014. The goal of the exercise was to assess citizens’ values and preferences about potential asteroid detection, asteroid mitigation, and exploration-based technologies associated with NASA’s Initiative. This article discusses the portion of the forum that focused on the Asteroid Redirect Mission, an effort to redirect an asteroid into lunar orbit that astronauts can study. The forum sought public input on two options for performing the mission that NASA included in technical assessments to make a down select decision: Option A to capture a 10-meter-diameter asteroid; or Option B to redirect a several-meters-diameter boulder from the surface of a larger asteroid. We describe the values and perceptions participants had about Option A and B, how these results were used by NASA managers, and the impact the results of the pTA had on the down select.     

System architecture practices to facilitate Department of Defense technology transfer

This paper explores the possibilities of combining DOD technology transfer mechanisms to systems architecture techniques as a means to shorten program acquisition timelines while still providing high technology, robust tools to the women and men serving in the United States military. A literature search demonstrates that few articles have been published on the relationship between systems architecture and technology transfer. However, any DOD laboratory that employs more than 200 scientists and engineers is required by law to have a full time Office of technology transfer, so why has so little research been performed on the synergies between the two DOD disciplines? This paper will describe the ways that the systems architecture tools and practices, and technology transfer transactional mechanisms available to all DOD laboratories, can be utilized to increase knowledge sharing with small business and industry partners to shorten acquisition cycles.
