Correlates of load carriage and obstacle course performance among women

To examine correlates of the speed at which female soldiers carrying loads could cover 3.2 km on foot and traverse an obstacle course, 12 volunteers (mean +/- SD: 25.3 +/- 6 years, 166 +/- 7 cm, 61.3 +/- 7 kg) were timed over 3.2 km while carrying loads of 14, 27, and 41 kg, and while traversing an obstacle course with the two lighter loads. Pearson correlations showed that absolute VO_[2 max] and 3.2 km run time without a load were the best predictors of 3.2 km load carriage time for all loads. Also, larger subjects with greater muscle mass were able to carry the heaviest load faster than smaller, less muscular subjects, likely because the 41 kg load represented a smaller percentage of the former's bodyweight. Maximum number of sit-ups and push-ups, composite score of the Army Physical Fitness Test as well as body height were positively correlated with the speed at which some course segments were traversed.

Equivalence theorem for Schur optimality of experimental designs

An experimental design is said to be Schur optimal, if it is optimal with respect to the class of all Schur isotonic criteria, which includes Kiefer's criteria of _Φp${\Phi }_p$-optimality, distance optimality criteria and many others. In the paper we formulate an easily verifiable necessary and sufficient condition for Schur optimality in the set of all approximate designs of a linear regression experiment with uncorrelated errors. We also show that several common models admit a Schur optimal design, for example the trigonometric model, the first-degree model on the Euclidean ball, and the Berman's model.     

Using Visual Art Workshops with Female Survivors of Domestic Violence in Portugal and England: A Comparative Reflection

ABSTRACT

This paper provides a reflection on the use of visual art workshops in an interdisciplinary feminist project with female survivors of domestic violence living in refuges in England and Portugal. The paper discusses the fieldwork in each location with attention to the interaction between participants, between participants and the researcher/s, and the cultural and institutional structures influencing the research and the images produced. Despite some key differences in the context, the analysis highlights key resonances and commonalities amongst the objects that survivors of domestic abuse depicted in each location. We use the feminist notion of ‘giving voice’ as an analytical tool throughout the paper. The paper argues that ‘giving voice’ was not unproblematically accomplished by using visual methods and suggests that our understanding remained partial and often reliant on verbal narratives accompanying the visual images produced. We also highlight issues of power emerging when exhibiting art generated through the study.     

Gender and Infrastructure in the World Bank

This article conducts a critical analysis of the World Bank's current infrastructure strategy from a feminist perspective, arguing that failures to define gender and set meaningful targets and indicators have meant that gender has not been integrated into the implementation of infrastructure projects. It sets out three limitations to the Bank's approach to gender and infrastructure: lack of awareness of gender in the four sectors that comprise infrastructure; the Bank's narrow approach to gender equality and women's empowerment; and the failure of the Bank to mainstream gender in its current infrastructure strategy.     

Governing Ebola: between global health and medical humanitarianism

Medical humanitarianism and global health are two distinct but co-dependent spheres of global health security. Their actors differ in their units of analysis, understanding of neutrality, and organizational capacities. While health underpins the normative principles of humanitarian action, humanitarian ideas, and notably medical humanitarian organizations, are absent from global health security planning. This article develops the work of Lakoff [‘Two regimes of global health’, Humanity, 1(1), 59–79 (2010)], distinguishing between these two governance spheres and how this had stark consequences in the 2014/15 Ebola outbreak in Liberia and Sierra Leone, framed as a problem of global health but which rapidly became a humanitarian crisis. Such a frame excluded medical humanitarian organizations from the initial global strategy and resulted in the creation of a new organization (UMMEER – United Nations Mission for Ebola Emergency Response) and the involvement of militaries to bridge the health-humanitarian divide. Reconciling the distinct but co-dependent relationship between medical humanitarianism and global health is fundamental to effective delivery of global health security.     

SIGN,SYMBOL, AND METALANGUAGE: AGAINST THE INTEGRATION OF SEMIOTICS AND SYMBOLIC INTERACTIONISM

Dean MacCannell's proposal for a “rapprochement” between symbolic interaction-ism and semiotics, in which the “generality” of symbolic interactionism's conception the sign is “raised” to that of semiotics, is examined. By turning exclusively to Saussurian semiotics, MacCannell does not adequately reflect the distinction between “natural” and “arbitrary” representation in Peirce's semiosis that is the most fruitful link with Mead's symbolic interactionism. Consequently, MacCannell's argument at the level of terminology is flawed. Rather than merging, the perspectives might benefit from a radical rethinking of representation. This would involve preserving the distinction between the “natural” and “arbitrary,” while at the same time recognizing that in mass society “arbitrary” representation has become a kind of “second-order” (Barthes) indexical metalanguage of membership within which symbolic interaction may occur. As Baudrillard claims, “commutation of signs” has replaced “interaction of symbols,” yet strains against an unfulfilled symbolic demand. Efforts should be directed at generating a theory of representation capable of addressing the tension that produces this symbolic demand.
