Disability Studies and Disaster Services: Putting the âDSâ in âDSâ
This article is a synopsis of articles found in this special issue of the Review of Disability Studies that focused on disability and disaster. In this article, information is gleaned and summarized from all the historical, research, and current events discussed in this issue. As part of the synopsis, the question is posed, âHow can Disability Studies, as an academic and social endeavor, inform disaster services?â Examples from various articles are provided to inform readers how âDSâ (disability studies) might influence âDSâ (disaster services)
Who is Disabled? Who is Not? Teachers Perceptions of Disability in Lesotho
This paper reports on educational research conducted in Lesotho, Southern Africa. Mixed methods of research were used to elicit and describe teachersâ attitudes toward children they perceived as disabled. The study took place in a country where discussions on âthe continuumâ of services, specialist diagnoses, and Western notions of assistive technology are largely irrelevant. Over-arching themes are compared to themes that have emerged from special education and Disability Studies literature over the past decade
Educational Leadership in the Era of Accountability
Recent changes in federal legislation, including the No Child Left Behind Act of 2001 (NCLB), have placed greater emphasis on accountability via mandated reporting of performance measures
Control of Aggregated Bacterial Communities through Engineered Surface Displayed Proteins
Bacterial aggregation through surface display of cross-associating proteins has previously been demonstrated, but the formation of these aggregates is only controllable and reversible through the addition of chemical inducers or soluble proteins. Here, we present a design for a photoswitchable surface-display system that causes bacterial aggregation. This system should reversibly disaggregate under exposure to blue light. We created our mutant by modifying Photoactive Yellow Protein (PYP), a fluorescent protein that undergoes a large reversible conformational change when exposed to blue light. We computationally designed this mutant to drive photoswitchable sequestration of a cap domain that is designed to selectively aggregate with SynZip18. Characterization of this designed protein's photoactivity was inconclusive due to its limited solubility though the synthesized chormophore, a p-coumaric acid derivative, was capable of reconstituting native photoactive PYP. While we did not show that the designed mutant could cause disaggregation under exposure to blue light, it was capable of selectively aggregating with surface displayed SynZip18 as desired.</p
Lâanalyse du discours et les Ă©tudes rhĂ©toriques
Ce texte est une introduction Ă un ouvrage intitulĂ© La rhĂ©torique en dĂ©tail, qui se propose de montrer lâimportance de lâanalyse du discours pour les Ă©tudes de rhĂ©torique telles quâelles sont aujourdâhui pratiquĂ©es aux Etats-Unis. Il insiste sur la façon dont une attention soutenue Ă la matĂ©rialitĂ© du langage peut enrichir les diverses branches de la rhĂ©torique contemporaine en prĂ©sentant une mĂ©thode fondĂ©e sur lâĂ©tude concrĂšte des textes qui vise Ă dĂ©gager leur logique interne. Il offre ce faisant une dĂ©finition de lâanalyse du discours, une rĂ©flexion sur la question de lâagentivitĂ©, et une « heuristique » dans le sens dâun « un ensemble de procĂ©dures de dĂ©couverte Ă appliquer mĂ©thodiquement ».This text is the introduction to a book entitled Rhetoric in Detail that is intended to demonstrate the importance of Discourse Analysis for American Rhetorical Studies. It emphasizes the contribution that close attention to language can make to various branches of contemporary rhetoric, and offers an empirical approach based on the study of actual texts and talk, looking for their internal logic. It provides a definition of Discourse Analysis as well as an approach to the question of agency, and a heuristic in the sense of a âset of discovery procedures for systematic application
Response of the Agile Antechinus to Habitat Edge, Configuration and Condition in Fragmented Forest
Habitat fragmentation and degradation seriously threaten native animal communities. We studied the response of a small marsupial, the agile antechinus Antechinus agilis, to several environmental variables in anthropogenically fragmented Eucalyptus forest in south-east Australia. Agile antechinus were captured more in microhabitats dominated by woody debris than in other microhabitats. Relative abundances of both sexes were positively correlated with fragment core area. Male and female mass-size residuals were smaller in larger fragments. A health status indicator, haemoglobin-haematocrit residuals (HHR), did not vary as a function of any environmental variable in females, but male HHR indicated better health where sites' microhabitats were dominated by shrubs, woody debris and trees other than Eucalyptus. Females were trapped less often in edge than interior fragment habitat and their physiological stress level, indicated by the neutrophil/lymphocyte ratio in peripheral blood, was higher where fragments had a greater proportion of edge habitat. The latter trend was potentially due to lymphopoenia resulting from stress hormone-mediated leukocyte trafficking. Using multiple indicators of population condition and health status facilitates a comprehensive examination of the effects of anthropogenic disturbances, such as habitat fragmentation and degradation, on native vertebrates. Male agile antechinus' health responded negatively to habitat degradation, whilst females responded negatively to the proportion of edge habitat. The health and condition indicators used could be employed to identify conservation strategies that would make habitat fragments less stressful for this or similar native, small mammals
