TL;DR: A need for nurses, and especially public health nurses who work with refugee and immigrant populations in the community, to develop a more comprehensive understanding of the range of refugee women's experiences and the continuum of needs post-migration, particularly among older women with large family responsibilities is suggested.
Abstract: This paper reports a study identifying the demographic characteristics self-reported trauma and torture prevalence and association of trauma experience and health and social problems among Somali and Oromo women refugees. Nearly all refugees have experienced losses and many have suffered multiple traumatic experiences including torture. Their vulnerability to isolation is exacerbated by poverty grief and lack of education literacy and skills in the language of the receiving country. Using data from a cross-sectional population-based survey conducted from July 1999 to September 2001 with 1134 Somali and Oromo refugees living in the United States of America a sub-sample of female participants with clearly identified parenting status (n = 458) were analysed. Measures included demographics history of trauma and torture scales for physical psychological and social problems and a post-traumatic stress symptom checklist. Results indicated high overall trauma and torture exposure and associated physical social and psychological problems. Women with large families reported statistically significantly higher counts of reported trauma (mean 30 P < 0.001) and torture (mean 3 P < 0.001) and more associated problems (P < 0.001) than the other two groups. Women who reported higher levels of trauma and torture were also older (P < 0.001) had more family responsibilities had less formal education (P < 0.001) and were less likely to speak English (P < 0.001). These findings suggest a need for nurses and especially public health nurses who work with refugee and immigrant populations in the community to develop a more comprehensive understanding of the range of refugee womens experiences and the continuum of needs post-migration particularly among older women with large family responsibilities. Nurses with their holistic framework are ideally suited to partner with refugee women to expand their health agenda beyond the biomedical model to promote healing and reconnection with families and communities.

TL;DR: It was found that a higher pH was required to solubilize protoxins from inclusions from the plasmid-cured strain than from B. thuringiensis subsp.
Abstract: Bacillus thuringiensis subsp. aizawai HD133 is one of several strains particularly effective against Plodia interpunctella selected for resistance to B. thuringiensis subsp. kurstaki HD1 (Dipel). B. thuringiensis subsp. aizawai HD133 produces inclusions containing three protoxins, CryIA(b), CryIC, and CryID, and the CryIC protoxin has been shown to be active on resistant P. interpunctella as well as on Spodoptera larvae. The CryIA(b) protoxin is very similar to the major one in B. thuringiensis subsp. kurstaki HD1, and as expected, this protoxin was inactive on resistant P. interpunctella. A derivative of B. thuringiensis subsp. aizawai HD133 which had been cured of a 68-kb plasmid containing the cryIA(b) gene produced inclusions comprising only the CryIC and CryID protoxins. Surprisingly, these inclusions were much less toxic for resistant P. interpunctella and two other Lepidoptera than those produced by the parental strain, whereas the soluble protoxins from these strains were equally effective. In contrast, inclusions from the two strains were about as active as soluble protoxins for Spodoptera frugiperda larvae, so toxicity differences between inclusions may be due to the solubilizing conditions within particular larval guts. Consistent with this hypothesis, it was found that a higher pH was required to solubilize protoxins from inclusions from the plasmid-cured strain than from B. thuringiensis subsp. aizawai HD133, a difference which is probably attributable to the absence of the CryIA(b) protoxin in the former. The interactions of structurally related protoxins within an inclusion are probably important for solubility and are thus another factor in the effectiveness of B. thuringiensis isolates for particular insect larvae.

Abstract: The human genome holds an extraordinary trove of information about human development, physiology, medicine and evolution. Here we report the results of an international collaboration to produce and make freely available a draft sequence of the human genome. We also present an initial analysis of the data, describing some of the insights that can be gleaned from the sequence.

TL;DR: A theory of intergroup conflict and some preliminary data relating to the theory is presented in this article. But the analysis is limited to the case where the salient dimensions of the intergroup differentiation are those involving scarce resources.
Abstract: This chapter presents an outline of a theory of intergroup conflict and some preliminary data relating to the theory. Much of the work on the social psychology of intergroup relations has focused on patterns of individual prejudices and discrimination and on the motivational sequences of interpersonal interaction. The intensity of explicit intergroup conflicts of interests is closely related in human cultures to the degree of opprobrium attached to the notion of "renegade" or "traitor." The basic and highly reliable finding is that the trivial, ad hoc intergroup categorization leads to in-group favoritism and discrimination against the out-group. Many orthodox definitions of "social groups" are unduly restrictive when applied to the context of intergroup relations. The equation of social competition and intergroup conflict rests on the assumptions concerning an "ideal type" of social stratification in which the salient dimensions of intergroup differentiation are those involving scarce resources.
