Insights Into the Remembered Educational Experiences of Male Caribbean Immigrants to Canada: Literacy and Identity in the Canadian Classroom

Abstract Past research has addressed the issue of male underachievement in literacy as an issue of global concern. This qualitative study focused on one subgroup of males which the literature highlighted as most at risk of educational underachievement in the Canadian educational landscape: male Caribbean immigrants to Canada. The research questions that framed the study sought to gain insight into the educational experiences of this group of learners so that ways through which their literacy achievement as measured by academic performance and classroom engagement could be projected. New literacy studies view literacy as socioculturally bound in social, institutional, and cultural relationships (Gee 1996). Literacy can therefore be thought of as an extension of self that Lankshear and Knobel (2006) assert is always connected to social identities. Central to the research questions as a result of this perspective was the discovery of the ideologies of reading held by the participants and their connections to literacy practice. Supplementary questions delved into socially valued literacy practices and ways in which learners saw themselves as Black males reflected in the Canadian educational framework. In this qualitative study with an interview design, data were collected through individual semistructured interviews with the 4 participants and through a focus group session with all the participants. The findings depicted that identity, interests, and ideologies of reading all influenced the literacy practices and engagement of Caribbean males. The findings documented are valuable as they provide a fresh perspective surrounding the educational experiences of the male Caribbean learner and can present insights which can lead to enhanced academic engagement and improved student achievement for this group of learners.

La alianza de estados insulares pequeños y la securitización del cambio climático en la convención marco de Naciones Unidas sobre cambio climático (1992-2012)

La presente monografía busca explicar el proceso de securitización realizado por la AOSIS del cambio climático en las COP de la CMNUCC. Esta investigación defiende que la AOSIS sí ha hecho dicho proceso a través de estrategias como el liderazgo moral y los nexos con actores no-estatales; pero dicho proceso no ha sido exitoso, dado el predominio del discurso del desarrollo sostenible en las negociaciones, el debilitamiento de la AOSIS como actor securitizador y el poco apoyo formal de las potencias emergentes y el bloque UMBRELLA. Para sustentar lo anterior, se realizará una revisión de informes científicos que demuestran que el cambio climático es una amenaza a la seguridad, y un estudio desde de la teoría de securitización de Thierry Balzacq, de los discursos dados por los estados AOSIS, de las COP y de las posiciones de algunos bloques de negociación sobre el cambio climático.

Comparison of two immunochromatographic assays and the indirect immunofluorscence antibody test for diagnosis of Trypanosoma cruzi infection in dogs in south central Louisiana

Two rapid tests evaluated in dogs considered to be of high risk of Infection with the Chagas parasite Trypanosoma cruzi using two immunochromatographic assays. Trypanosoma Detect (TM) for canine, InBios, Seattle, WA and CHAGAS STAT-PAK (TM) assay, Chembio Diagnostic Systems, Medford, NY, in south central Louisiana. For this purpose a serological survey was carried out in a total of 122 dogs and a serum bank was created. These 122 animals were first tested by IFAT that was used as the standard test From the serum bank 50 samples were tested using the two rapid Chagas assays and results compared to the standard test IFAT The serological survey using IFAT showed it prevalence of T cruzi infection in 22.1% of the tested dogs. In the immunochromatographic assays. 13 and 11 animals were positive on rapid assay Trypanosoma Detect (TM) for canine, InBios and CHAGAS STAT-PAK (TM), Chembio Diagnostic Systems, respectively compared to 11 positive by IFAT. These two immunochromatographic tests have shown high susceptibility and specificity compared to our standard method IFAT. The rapid, easy and accurate screening assays used in conjunction with confirmatory tests, would be an excellent tool for veterinarians to diagnose T cruzi infection. Early detection of T cruzi infection may prevent complications through an effective treatment. Greater awareness by veterinarians of the risk. clinical findings, history along with diagnostic methods will contribute greatly to an understanding of the true prevalence of Chagas disease in dogs in Louisiana.

Nitric oxide regulates vascular cell adhesion molecule 1 gene expression and redox-sensitive transcriptional events in human vascular endothelial cells.

Decreased nitric oxide (NO) activity, the formation of reactive oxygen species, and increased endothelial expression of the redox-sensitive vascular cell adhesion molecule 1 (VCAM-1) gene in the vessel wall are early and characteristic features of atherosclerosis. To explore whether these phenomena are functionally interrelated, we tested the hypothesis that redox-sensitive VCAM-1 gene expression is regulated by a NO-sensitive mechanism. In early passaged human umbilical vein endothelial cells and human dermal microvascular endothelial cells, the NO donor diethylamine-NO (DETA-NO, 100 microM) reduced VCAM-1 gene expression induced by the cytokine tumor necrosis factor alpha (TNF-alpha, 100 units/ml) at the cell surface level by 65% and intracellular adhesion molecule 1 (ICAM-1) gene expression by 35%. E-selectin gene expression was not affected. No effect on expression of cell adhesion molecules was observed with DETA alone. Moreover, DETA-NO suppressed TNF-alpha-induced mRNA accumulation of VCAM-1 and TNF-alpha-mediated transcriptional activation of the human VCAM-1 promoter. Conversely, treatment with NG-monomethyl-L-arginine (L-NMMA, 1 mM), an inhibitor of NO synthesis, augmented cytokine induction of VCAM-1 and ICAM-1 mRNA accumulation. By gel mobility shift analysis, DETA-NO inhibited TNF-alpha activation of DNA binding protein activity to the VCAM-1 NF-kappa B like binding sites. Peroxy-fatty acids such as 13-hydroperoxydodecanoeic acid (linoleyl hydroperoxide) may serve as an intracellular signal for NF-kappa B activation. Using thin layer chromatography, DETA-NO (100 microM) suppressed formation of this metabolite, suggesting that DETA-NO modifies the reactivity of oxygen intermediates in the vascular endothelium. Through this mechanism, NO may function as an immunomodulator of the vessel wall and thus mediate inflammatory events involved in the pathogenesis of atherosclerosis.

Expression of a delta 9 14:0-acyl carrier protein fatty acid desaturase gene is necessary for the production of omega 5 anacardic acids found in pest-resistant geranium (Pelargonium xhortorum).

Anacardic acids, a class of secondary compounds derived from fatty acids, are found in a variety of dicotyledonous families. Pest resistance (e.g., spider mites and aphids) in Pelargonium xhortorum (geranium) is associated with high levels (approximately 81%) of unsaturated 22:1 omega 5 and 24:1 omega 5 anacardic acids in the glandular trichome exudate. A single dominant locus controls the production of these omega 5 anacardic acids, which arise from novel 16:1 delta 11 and 18:1 delta 13 fatty acids. We describe the isolation and characterization of a cDNA encoding a unique delta 9 14:0-acyl carrier protein fatty acid desaturase. Several lines of evidence indicated that expression of this desaturase leads to the production of the omega 5 anacardic acids involved in pest resistance. First, its expression was found in pest-resistant, but not suspectible, plants and its expression followed the production of the omega 5 anacardic acids in segregating populations. Second, its expression and the occurrence of the novel 16:1 delta 11 and 18:1 delta 13 fatty acids and the omega 5 anacardic acids were specific to tall glandular trichomes. Third, assays of the recombinant protein demonstrated that this desaturase produced the 14:1 delta 9 fatty acid precursor to the novel 16:1 delta 11 and 18:1 delta 13 fatty acids. Based on our genetic and biochemical studies, we conclude that expression of this delta 9 14:0-ACP desaturase gene is required for the production of omega 5 anacardic acids that have been shown to be necessary for pest resistance in geranium.
