A Aplicação da Etnografia Crítica nas Relações de Poder

A utilização da etnografia tradicional não é um fenómeno novo no domínio da investigação qualitativa. Antropólogos e, de seguida, sociólogos privilegiaram esta abordagem metodológica desde há muito tempo. Em meados dos anos 1970, alguns investigadores « críticos » voltaram-se para a etnografia enquanto abordagem de investigação, porque lhes permitia perceber melhor a realidade dos grupos oprimidos, e, deste modo, compreender melhor as realções de poder e o modo como elas evoluem. O presente artigo procura demonstrar a pertinência da etnografia crítica no exame das relações de poder. Os resultados de dois estudos etnográficos servem para mostrar de que modo a abordagem etnográfica permite um exame mais aprofundado das práticas sociais existentes, permitindo assim ao investigador dissecar no plano teórico a noção de poder. A análise comparativa de resultados apresentados centram-se nas minorias linguísticas no Canadá, sejam francófonos que vivem no exterior do Quebeque sejam anglófonos vivendo no Quebeque. A análise comparativa demonstra que as relações de poder não se situam somente entre as duas minorias linguísticas e a sua maioria respetiva, mas também entre as próprias minorias linguísticas.

Uso da Internet na elaboração do trabalho de conclusão de curso pelos alunos de Enfermagem

A enfermagem se destaca como consumidora de tecnologia em diversos contextos: ensino, pesquisa e assistência. Como os alunos do curso de Enfermagem utilizam a internet para o processo de produção de Trabalhos de Conclusão de Curso (TCC)? Com o intuito de responder a essa questão e compreender melhor como a internet vem sendo utilizada na construção dos TCC dos alunos de Enfermagem, este trabalho tem os seguintes objetivos: avaliar a utilização da internet na elaboração de TCC; investigar o uso da internet por esses; identificar as bases de dados utilizadas; levantar as principais dificuldades e/ou facilidades; e descrever como a internet é usada para buscar a literatura produzida. Trata-se de um estudo descritivo, seccional, com abordagem quantitativa, desenvolvido em duas instituições de ensino superior em Teresina – Piauí, sendo uma de caráter privado e outra de caráter público. A pesquisa teve como amostragem os alunos de Enfermagem do 8º período das duas instituições. É relevante considerar que o acesso democrático e a falta de conhecimento frente à internet ainda são realidade em nossa sociedade, o que nos remete à necessidade de implementar estratégias de educação relacionadas à utilização da internet como ferramenta para a construção do conhecimento em saúde e enfermagem.

Population Assessment of an Endangered Shorebird: the Piping Plover (Charadrius melodus melodus) in Eastern Canada

Small, at-risk populations are those for which accurate demographic information is most crucial to conservation and recovery, but also where data collection is constrained by logistical challenges and small sample sizes. Migratory animals in particular may experience a wide range of threats to survival and reproduction throughout each annual cycle, and identification of life stages most critical to persistence may be especially difficult for these populations. The endangered eastern Canadian breeding population of Piping Plover (Charadrius melodus melodus) was estimated at only 444 adults in 2005, and extensive effort has been invested in conservation activities, reproductive monitoring, and marking of individual birds, providing a comprehensive data set on population dynamics since 1998. We used these data to build a matrix projection model for two Piping Plover population segments that nest in eastern Canada in order to estimate both deterministic and stochastic rates of population growth (λd and λs, respectively). Annual population censuses suggested moderate growth in abundance between 1998–2003, but vital rate estimates indicated that this temporary growth may be replaced by declines in the long term, both in southern Nova Scotia (λd = 1.0043, λs = 0.9263) and in the Gulf of St. Lawrence (λd = 0.9651, λs = 0.8214). Nonetheless, confidence intervals on λ estimates were relatively wide, highlighting remaining uncertainty in future population trajectories. Differences in projected growth between regions appear to be driven by low estimated juvenile post-fledging survival in the Gulf, but threats to juveniles of both population segments following departure from nesting beaches remain unidentified. Similarly, λ in both population segments was particularly sensitive to changes in adult survival as expected for most migratory birds, but very little is understood about the threats to Piping Plover survival during migration and overwintering. Consequently, we suggest that future recovery efforts for these and other vulnerable migrants should quantify and manage the largely unknown sources of both adult and juvenile mortality during non-breeding seasons while maintaining current levels of nesting habitat protection.

Modeling Habitat Associations for the Common Loon (Gavia immer) at Multiple Scales in Northeastern North America

Common Loon (Gavia immer) is considered an emblematic and ecologically important example of aquatic-dependent wildlife in North America. The northern breeding range of Common Loon has contracted over the last century as a result of habitat degradation from human disturbance and lakeshore development. We focused on the state of New Hampshire, USA, where a long-term monitoring program conducted by the Loon Preservation Committee has been collecting biological data on Common Loon since 1976. The Common Loon population in New Hampshire is distributed throughout the state across a wide range of lake-specific habitats, water quality conditions, and levels of human disturbance. We used a multiscale approach to evaluate the association of Common Loon and breeding habitat within three natural physiographic ecoregions of New Hampshire. These multiple scales reflect Common Loon-specific extents such as territories, home ranges, and lake-landscape influences. We developed ecoregional multiscale models and compared them to single-scale models to evaluate model performance in distinguishing Common Loon breeding habitat. Based on information-theoretic criteria, there is empirical support for both multiscale and single-scale models across all three ecoregions, warranting a model-averaging approach. Our results suggest that the Common Loon responds to both ecological and anthropogenic factors at multiple scales when selecting breeding sites. These multiscale models can be used to identify and prioritize the conservation of preferred nesting habitat for Common Loon populations.

Piping Plover response to coastal storms occurring during the nonbreeding season

The increase in coastal storm frequency and intensity expected under most climate change scenarios is likely to substantially modify beach configuration and associated habitats. This study aimed to analyze the impact of coastal storms on a nesting population of the endangered Piping Plover (Charadrius melodus melodus) in southeastern New Brunswick, Canada. Previous studies have shown that numbers of nesting Piping Plovers may increase following storms that create new nesting habitat at individual beaches. However, to our knowledge, no test of this pattern has been conducted over a regional scale. We hypothesized that Piping Plover abundance would increase after large coastal storms occurring during the nonbreeding season. However, we expected a delay in the colonization of newly created habitat owing to low-density populations, combined with high site fidelity of adults and high variability in survival rate of subadults. We tested this hypothesis using a 27-year (1986-2012) data set of Piping Plover abundance and productivity (nesting pairs and fledged young) collected at five sites in eastern New Brunswick. We identified 11 major storms that could potentially have modified Piping Plover habitat over the study period. The number of fledged young increased three years after a major storm, but the relationship was much weaker for the number of nesting pairs. These findings are consistent with the hypothesized increase in suitable habitat after coastal storms. Including storm occurrence with other factors influencing habitat quality will enhance Piping Plover conservation strategies.
