The morphogenesis of electrically and heat-induced dermal changes in pig skin

In order to establish pathological evidence in dermis for distinguishing between sequelae of electrical torture and those of other superficial injuries, the skin of eleven fully anaesthetized Danish Landrace pigs have been exposed to heat and electrical energy from either 50 Hz alternating current (a.c.) or direct current (d.c.) via 12 mm large contact knobs or via a pointed 0.5 mm large electrode (only 50 Hz a.c.). The lesions have been examined from 1 to 126 days after the injury. While heat lesions exposed to energy lower than 60 joule only gave minor changes, heat lesions exposed to more than 60 joule showed changes in both collagen fibres (basophilic or eosinophilic fibres without any birefringence or coarse cross-striation in polarized light, respectively) and dermal cells (granular cytoplasm). Areas exposed to 50 Hz a.c. via 0.5 mm. electrode showed basophilic collagen fibres and in a few biopsies on day 7 calcium salts on collagen fibres. Using 12 mm large electrodes the changes were minor, but basophilic and eosinophilic collagen fibres with no birefringence or with fine/coarse cross-striation respectively were seen. Even cells with 'vesicular nuclei' were seen on day 1 and 2 after the injury. The changes in the anode area showed resemblance to that of heat lesions (basophilic collagen fibres). Eosinophilic collagen fibres with fine densely spaced cross-striation in polarized light and 'vesicular nuclei' as well as collagen fibres with calcium salts were seen in the cathode lesions. It is concluded that the dermal changes in the cathode area are specific for electrical injury from day 1 to 14. However, earlier studies have demonstrated dermal changes specific for electrical injury at day 0 and the presence of calcified collagen fibres up to 2 months after injury. The dermal changes in anode lesions were non specific and could not be differentiated from those found in heat lesions. Alternating current lesions (50 Hz) were specific from day 1 to day 7, when the pointed electrode was used, but only in a few days when the energy was transferred via the 12-mm electrodes.     

A Comparative Study of Denmark and New Zealand’s National Health Targets

This paper investigates the influence of nationally imposed health targets on current management control practices in New Zealand and Denmark. It reveals how variants of New Public Management (NPM), arising from specific historical socio-political contexts, rise to the challenge of national differences. The study finds that both nations are challenged to ensure data registration procedures produce valid and comparable performance measures. Denmark’s reliance on a single efficiency measure of health sector performance reflects a historic socio-political context that reduces the feasibility of additional measures whereas New Zealand’s context enables the government to impose a more extensive range of health targets.     

Measuring Policy Success: Evaluating Public Sector Reform in Bhutan

There has been resurgence in evaluation of policy, reflected mostly by an increase in ex ante studies. Although there is a shift towards ex post evaluation, this has been gradual, resulting in a paucity of ex post evaluation literature. To address this gap, we apply a revisionist approach to evaluate a major public sector reform in the Bhutanese civil service. We conclude that it provides a more holistic approach for ex post evaluation policy, and also a more nuanced evaluation which moves us beyond the narrow binary view of success or failure in reform.     

Subjected to Sanitation: Caste Relations and Sanitation Adoption in Rural Tamil Nadu

If solving the global sanitation crisis lies within Indian borders, then it is important to understand the influence of caste relations on sanitation building and usage. Our ethnography investigated three villages in rural Tamil Nadu where seven separate sanitation interventions had failed. The analysis indicates caste relations played a key role in the failed interventions by creating and reinforcing the means by which caste groups distinguished themselves from each other at the village scale. Issues of cleaning, access to subsidies, latrine design, and purity served to facilitate and limit the processes that enable the everyday, unequal relationships of caste.     

Identifying Spatial Efficiency–Equity Trade-offs in Territorial Development Policies: Evidence from Uganda

Abstract

We contribute to the debate on the spatial allocation of infrastructure investments by examining where these investments generate the highest economic return (‘spatial efficiency’), and identifying trade-offs when infrastructure coverage is made more equitable across regions (‘spatial equity’). We estimate models of firm location choice in Uganda, drawing on insights from the new economic geography literature. The main findings show that manufacturing firms gain from being in areas that offer a diverse mix of economic activities. Public infrastructure investments in other locations are likely to attract fewer private investors, and will pose a spatial efficiency–equity trade-off.     

Gender paradoxes and power—theoretical reflections with empirical awareness

Gender awareness and gender neutrality are discussed with the aid of post‐structuralist gender theories concerning paradoxes and aporias. Via paradox thinking, women's, men's and gender studies are challenged to develop perspectives on gender that are both thought and not thought, said and not said, done and not done. Paradoxes are understood as aporias, in which the researcher gets into “stuck places”. Gender dualism is put to the test as a fundamental concept. Various theories of power, such as patriarchy theories, theories of hegemonic power, and gender and queer‐theories of symbolic and discursive power are associated with gender paradoxes and gender dualism. Examples are included from the author's own research in school and gender studies.     

A Prospective Study of Mexican American Adolescents’ Academic Success: Considering Family and Individual Factors

Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family (i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism, gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further, being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade academic performance. Implications for future research and interventions are discussed.     

Social Competence in Late Elementary School: Relationships to Parenting and Neighborhood Context

Despite evidence that neighborhoods confer both risk and resilience for youth development, the existing neighborhood research has a number of methodological limitations including lack of diversity in neighborhoods sampled and neighborhood characteristics assessed. The purpose of this study was to address these methodological limitations of existing research and to examine the relationship of neighborhood structural and social characteristics to family-level social processes and teacher-reported social competence during early adolescence. The study sample of 3,624 fifth graders (51?% girls) was ethnically diverse, including roughly even proportions of non-Hispanic White, non-Hispanic Black, and Hispanic youth. Neighborhood measures included economic disadvantage derived from the U.S. Census, physical and social disorder obtained by direct observation, and social capital from parental reports. Family-level social processes included parent reported family cohesion and youth reported maternal and paternal nurturance. We found that neighborhood factors significantly associated with youth social aggression and social competence but not social withdrawal, after controlling for individual demographic characteristics and parenting factors. There was limited evidence of moderation of family influences by neighborhood characteristics as well as the moderation of neighborhood effects by children’s gender. Neighborhood physical disorder was associated with increased social aggression among boys but with increased social withdrawal among girls. Implications of the study’s findings for research on neighborhoods and adolescent development and the development of preventive interventions are discussed.
