Estudo dos flebótomos (Diptera, Phlebotominae), vectores de Leishmania sp. No Concelho de Torres Novas, Portugal

Estudo dos flebótomos (Diptera, Phlebotominae), vectores de Leishmania sp. no Concelho de Torres Novas, Portugal. Sofia Isabel Martins Branco PALAVRAS-CHAVE: flebótomos, bioecologia, Leishmania, Torres Novas, Portugal. Os flebótomos são insectos vectores de vários agentes patogénicos, dos quais se destacam os protozoários do Género Leishmania. Em Portugal, as leishmanioses, canina e humana, são causadas por L. infantum, sendo o cão o principal reservatório e Phlebotomus perniciosus e P. ariasi os vectores comprovados do parasita. São conhecidos três focos de doença, mas casos de leishmaniose canina têm sido reportados em outras regiões nas quais se desconhecem as espécies flebotomínicas presentes e respectivas taxas de infecção. Neste trabalho, efectuou-se a primeira prospecção flebotomínica no Concelho de Torres Novas, Distrito de Santarém, localizado na região Centro de Portugal. Os principais objectivos foram determinar a fauna flebotomínica do Concelho, os aspectos bioecológicos, as taxas de infecção por Leishmania e os factores de risco para a transmissão vectorial. De Junho a Novembro de 2010, 275 biótopos foram prospectados com armadilhas CDC. As capturas foram realizadas em 91 localidades, nas 17 freguesias do Concelho, e incluíram habitats domésticos, peridomésticos e silváticos. Os exemplares capturados foram identificados morfologicamente, as fêmeas utilizadas para detecção molecular de DNA de Leishmania e identificação das refeições sanguíneas. Análises de regressão simples e múltipla foram utilizadas para avaliação dos factores de risco para a presença das várias espécies flebotomínicas. Testes não paramétricos foram usados para comparar densidades. Dos 1262 flebótomos capturados, quatro espécies foram assinaladas com as seguintes abundâncias relativas: P. perniciosus 73,69%, P. ariasi 8,16%, P. sergenti 6,58% e Sergentomyia minuta 11,57%. Em 82% das localidades prospectadas foi detectada pelo menos uma espécie flebotomínica e em 71,4% destas foi capturada pelo menos uma das espécies comprovadamente vectoras de L. infantum. P. perniciosus foi assinalado em todas as 17 freguesias do Concelho. Os factores de risco identificados foram: temperaturas elevadas e humidades relativas baixas, locais abrigados e ausência de vento forte, presença de pinheiros como vegetação dominante, biótopos peridomésticos, particularmente currais de ovelhas e coelheiras, ou na proximidade de ovelhas, aves de capoeira e ninhos com andorinhas. A taxa de infecção flebotomínica por L. infantum foi de 4% para P. ariasi e de 0,32% para o total de fêmeas capturadas. A maioria das fêmeas para as quais se identificou a origem da refeição sanguínea pertencia a P. perniciosus. Esta espécie apresentou um comportamento oportunista, alimentando-se numa grande variedade de hospedeiros vertebrados. A elevada abundância e distribuição das espécies vectoras, juntamente com a seroprevalência de Leishmania nos cães do Distrito (5-10%), e a captura de uma fêmea grávida de P. ariasi (infectante), sugerem que o Concelho de Torres Novas é um foco de leishmaniose no país. A maior abundância relativa de P. sergenti, comparando com prospecções realizadas noutras áreas da região Centro de Portugal, sugere que este potencial vector esteja a expandir-se para latitudes mais elevadas, aumentando o risco de introdução de L. tropica no território, por contacto com imigrantes ou viajantes infectados de áreas endémicas. A monitorização flebotomínica, e dos hospedeiros vertebrados, deverá ser continuada no Concelho para que medidas eficazes de controlo possam ser definidas e implementadas.

Learning and healing: a wellness pedagogy for Aboriginal teacher education /

During the last 30 years Aboriginal peoples in Canada have made steady progress in reclaiming the responsibility for the education of their young people, especially in primary and secondary school. In comparison the education and or training of adult populations has not kept pace and many socioeconomic and sociocultural indicators demonstrate a ' , continued confinement of those populations to the margins of the dominant society of Canada. It is the adults, the mothers and the fathers, the grandmothers and grandfathers, the aunties and uncles that are the first teachers of the next generation and the nature of these relationships replicates the culture of unwellness in each subsequent generation through those teachers. There are few examples in the Aboriginal adult education literatures that give voice to the educational experience of the Learner. This study addresses that gap by exploring the perspectives embedded in the stories of a Circle of Learners who are, or were enrolled in the Bachelor of Education in Aboriginal Adult Education program at Brock University. That Circle of 1 participants included 9 women and 1 man, 6 of whom were from various i Anishinabek nations while 4 represented the Hotinonshd:ni nations in southern Ontario. They are an eclectic group, representing many professions, age groups, spiritual traditions, and backgrounds. This then is their story, the story of the heaming and Healing pedagogy and an expanded vision of Aboriginal education and research at Brock University.

Stolen past: Shattered futures, aboriginal justice in Canada

It is acknowledged that Canada's criminal justice system has some major flaws, particularly with respect to its application to various ethnic subgroups. Aboriginal Canadians are one subgroup particularly sensitive to the problems in the system as is reflected by their disproportionately high rates of criminality and incarceration. Over the past 50 years many programs have been developed and recommendations have been made to alleviate the tensions Aboriginals find within the system. However, the situation today is essentially the same. Aboriginals are still overrepresented within the system and solutions that have been brought forward have had little success in stemming their flow into the system. Blame for Aboriginal mistreatment in the system has been placed at all levels from line police officers to high-level officials and politicians and attempts to resolve problems continue as an on going process. However, many of the recommendations and reforms have revolved around culture conflict. Although this thesis recognizes the importance of culture conflict in the overrepresentation of Aboriginals within the Canadian criminal justice system, it has also recognized that culture conflict alone is not responsible for all the flaws within the system as it pertains to Aboriginals. This thesis is of the opinion that in order for reforms to the criminal justice system to be successful, the context in which the system is operating must also be considered. Variables such as geographic isolation, economic disparity and social/political stability are viewed as operating in conjunction with culture, ultimately influencing Aboriginal treatment within the system. The conclusions drawn from this study confirm that when these factors operate together, the overrepresentation of Aboriginals within the Canadian criminal justice system is inevitable. Thus all three variables, culture conflict (social/political stability being part), geographic isolation and economic disparity must be address within the system if any significant changes in the crime rates or incarceration rates of Aboriginals is to be expected. In addition, primary research indicated the influence of cooperation as a factor in moderating the effects of criminality; not just cooperation among Aboriginals and non-Aboriginals, but also cooperation among differing Aboriginal communities. It was argued that when all these issues are addressed, Aboriginal peoples in Canada will have the strength to repair their shattered futures.

The journey towards comprehensive school health within an aboriginal community

The purpose of this research is to describe the journey towards Comprehensive School Health at two Aboriginal elementary schools. An advocate and a healthy schools committee were identified at both schools and were responsible for developing initiatives to create a healthy school community. A case study was used to gather an in-depth understanding of Comprehensive School Health for the two schools involved. As a researcher, I functioned within the role of a participantobserver, as I was actively involved in the programs and initiatives completed in both schools. The research process included: the pilot study, ethics clearance and distribution of letters of invitation and consent forms. Data collection included 16 semi-structured, guided interviews with principals, teachers, and stupents. Participant observations included sites of the gymnasium, classroom, playgrounds, school environments, bulletin boards as well as artifact analysis of decuments such as school newsletters, physical education schedules and school handbooks. The interviews were transcribed and coded using an inductive approach which involves finding patterns, themes and categories from the data (patton, 2002). Research questions guided the findings as physical activity, physical education, nutrition and transportation were discussed. Themes developed t~rough coding were teacherstudent interactions, cultural traditions, time constraints and professional development and were discussed using a Comprehensive School Health framework.

Aboriginal women in education : Honouring our experiences a vision of access to and success within the university

This thesis explores Aboriginal women's access to and success within universities through an examination of Aboriginal women's educational narratives, along with input from key service providers from both the Aboriginal and non-Aboriginal community. Implemented through the Wildfire Research Method, participants engaged in a consensusbased vision of accessible education that honours the spiritual, emotional, intellectual, and physical elements necessary for the success of Aboriginal women in university. This study positions Aboriginal women as agents of social change by allowing them to define their own needs and offer viable solutions to those needs. Further, it connects service providers from the many disconnected sectors that implicate Aboriginal women's education access. The realities of Aboriginal women are contextualized through historical, sociocultural, and political analyses, revealing the need for a decolonizing educational approach. This fosters a shift away from a deficit model toward a cultural and linguistic assets based approach that emphasizes the need for strong cultural identity formation. Participants revealed academic, cultural, and linguistic barriers and offered clear educational specifications for responsive and culturally relevant programming that will assist Aboriginal women in developing and maintaining strong cultural identities. Findings reveal the need for curriculum that focuses on decolonizing and reclaiming Aboriginal women's identities, and program outcomes that encourage balance between two worldviews-traditional and academic-through the application of cultural traditions to modern contexts, along with programming that responds to the immediate needs of Aboriginal women such as childcare, housing, and funding, and provide an opportunity for universities and educators to engage in responsive and culturally grounded educational approaches.

Understanding the Cultural Health Beliefs in Diabetes Education Amongst the Aboriginal Population within a City in the Southern Region of Ontario

This study examined the cultural health beliefs in diabetes education amongst the Aboriginal population within a city in Southern Ontario. The purpose was to contribute to the development of a culturally relevant diabetes handbook as well as to delivery styles within current diabetes education programs. To this end, a focus group was conducted with Aboriginal men and women between the ages of 18-70 years with type 2 diabetes. Participants were recruited from 2 Aboriginal community centres and an Aboriginal health centre in a city in Southern Ontario. Themes were drawn from the analysis of the focus group transcripts and combined with the findings from the research literature. The major themes that merged were drawn from Eurocentric and Aboriginal theories. The results were a set of recommendations on the type of format for diabetes educational programs such as traditional group activities, variety of electronic format, and culture specific educational resources. The emergent results appear to provide some important insights into program planning for diabetes education centres within Aboriginal communities.

Aboriginal Parental Involvement/Engagement for Student Success

An increasing body of knowledge links parental involvement with student success but few studies address Aboriginal parental involvement in urban settings. While some critics argue traditional Aboriginal knowledge is best delivered at home, Aboriginal children who share parents’ stories in the classroom benefit other children who draw connections to these stories. Moreover, Aboriginal learners need to function in mainstream Western society and in public school settings in which educators often have a difficult time engaging Aboriginal parents. Consequently, this research sought to explore the perceptions and sense of engagement of parents/caregivers in the Aboriginal Student Program (ASP) in a publicly funded secondary school in Ontario. The study was an extension of the researcher’s existing work and focused specifically on a sample of parents/caregivers taking part in an Aboriginal feast at an Ontario secondary school. Nine individuals accepted an invitation to participate in a Talking Circle and shared perceptions of their children’s educational experiences. Data were collected and coded, and findings indicated that parental involvement in children’s educational journeys contributed significantly to a sense of parental engagement in the school and in Aboriginal programs. Results also suggest that Eurocentric pedagogy can be modified in mainstream secondary schools to directly involve Aboriginal parents/caregivers. Although many participants’ stories revealed they experienced racism during their own schooling, study findings demonstrate that the parents/caregivers want to be involved in their children’s education nonetheless. This thesis discusses the data that were grounded in the participants’ voices that in turn led to several key recommendations.

Imagery, Technology, and Remote Adult Aboriginal Teacher Candidates: A Brock University Pilot Project

The aim of this thesis is to explore the relationship between imagery, technology, and remote adult Aboriginal teacher candidates through the computer software Elluminate Live. It focuses on the implications that the role imagery plays in third generation distance education with these learners and the new media associated therein. The thesis honours the Medicine Wheel teachings and is presented within this cyclical framework that reflects Indigenous philosophies and belief systems. In accordance, Sharing Circle as methodology is used to keep the research culturally grounded, and tenets of narrative inquiry further support the study. Results indicate there are strong connections to curricula enhanced with imagery—most notably a spiritual connection. Findings also reveal that identity associated to geographical location is significant, as are supportive networks. Third generation distance education, such as Elluminate Live, needs to be addressed before Aboriginal communities open the doors to all it encompasses, and although previous literature peers into various elements, this study delves into why the graphical interface resonates with members of these communities. Of utmost importance is the insight this thesis lends to the pedagogy that may possibly evoke a transformative learning process contributing to the success rate of Aboriginal learners and benefit Aboriginal communities as a whole.

Relationship Building with Aboriginal Elders in the Publicly Funded Secondary School Classroom: A Study of Ethical Space from an Aboriginal Persepective

This is a current story of ethical space in education that is often neglected in the design of educational experiences for Aboriginal students. This story is told through an Aboriginal lens rooted in the structured Two Row Wampum Belt relational agreement between Aboriginal peoples and Settlers. Through ethnographic narrative based on an extensive literature review, individual in-depth interviews, and a personal journal, this study documents the processes of acceptance, silence, complications, and then rejection to position Aboriginal Elders as inclusive bodies of knowledge in publicly funded secondary school classrooms. Aboriginal Elders are valued as Knowledge Holders, as Aboriginal teachers, guides, and mentors. Yet, the complexities of colonial rights, politics, and policies continue to intrude deeply into the lives of Aboriginal peoples to cause silence, confusion, and struggle rather than an evolution of new knowledge amongst two co-existing solitudes under the original terms of the Two Row Wampum Belt. The study was delayed and then came to an end when the school boards and local schools scrutinized its operating policies and unresolved funding issues. This study demonstrated that despite the Two Row Wampum Belt agreement that promised a co- existent relationship between Aboriginal peoples and Settlers, the strategy of inviting Aboriginal Elders to work alongside teachers in the classroom was viewed as being in conflict with the Settler’s institutional/educational objectivities, and, as such, was denied to Aboriginal students.
