Seu trabalho tem sido constantemente objeto de estudo por parte de um grande número de críticos e estudiosos que tem observado a grande preocupação da autora com questões de identidade, tanto do ponto de vista pessoal como nacional, e também com a questão do poder e da opressão. Dentre as várias formas que Margaret Atwood encontrou para expressar sua preocupação com as questões mencionadas acima, vários críticos detectaram o frequente aparecimento de elementos do mundo mágico dos romances e contos de fadas. Usando o conceito de "táticas revisionistas" apresentadas por Rachel Duplessis and Alicia S. Ostriker, o interesse aqui foi exatamente investigar o uso que Atwood faz de elementos de contos de fadas, especialmente para expressar sua preocupação com a questão da identidade feminina, tanto no nível pessoal como no artístico.

Forest fragmentation poses a serious danger to population diversity in plants and animals by increasing species isolation, thus reducing the population size and genetic diversity. However, little information is available concerning how fragmentation impacts plant diversity. AFLP fingerprinting was used to assess genetic diversity within and between populations of Asarum canadense L. (Canadian Wild Ginger) across 11 different populations in East-Central Indiana. AFLP fingerprints using two primer pairs generated 51 distinct bands with an average of 25.5 bands per primer. Forty-eight low molecular weight distinct polymorphic bands were observed (50-200 bp range). The percentage of polymorphism was low (0-25%) indicating low levels of genetic diversity within each population studied. NTSYSpc Numerical Taxonomy Analysis Software generated aphenogram that revealed high levels of homologies within populations (75-100%), with individuals from the same population typically clustered. The genetic diversity between populations ranged from 10-50%. The populations from Jay, Randolph and Henry Counties clustered together exhibiting -54% homology, while populations from Mien, Madison, and Huntington counties shared approximately 64% homology. The populations from Adams, Blackford, Delaware, and Grant counties shared approximately 66% homology. However, within this last group Blackford and Delaware counties shared 90% homology. There were no apparent effects of the size of the forest fragments on the observed diversity measures. A possible relationship between genetic diversity and spatial distance was observed between populations moving from east to west. Possible reasons for this observation may be due to forest types, age of forests, climatic factors, soil types, and/or anthropogenic activities. Overall, the low level of average diversity within the populations strongly suggests that the individuals inhabiting isolated forests primarily propagate by asexual means.Ball State UniversityMuncie, IN 47306 / Department of Biology

Para chegarem a esse ponto de auto-conhecimento, elas passam por uma série de diferentes momentos de crise e dúvidas, terminando por assumir o controle de suas próprias vidas, usando o espelho a partir de então em proveito próprio.

Orientador: Maria das Graças Gomes Villa da Silva / Banca: Ramira Maria Siqueira da Silva Pires / Banca: Nelson Viana / Resumo: Alice Munro destaca-se como grande autora de contos que, elaborados de forma renovada, desafiam a classificação do gênero e são caracterizados pelos finais em aberto. É no contraponto entre realismo, modernismo e pós-modernismo que Alice Munro constrói suas narrativas, um momento de transição e concepções renovadas a respeito do trabalho literário que, expresso em sua obra, conjuga os contrastes por meio de técnicas sofisticadas. A obra Lives of girls and women (2001), em destaque neste trabalho, é classificada como romance por alguns críticos - e até pela própria autora -, assumindo, por vezes, características de um Bildungsroman. No entanto, é constituída por contos, fragmentação que favorece a independência de cada narrativa, mas que não rompe definitivamente com a noção de continuidade, característica do romance. É nessa forma de trabalhar com o conto na obra citada que o projeto em questão se detém, buscando verificar como essa questão se dá dentro da estrutura do livro estudado e seus efeitos de sentido. Também constitui o objetivo do estudo identificar, em meio a essa fragmentação, o labirinto de vozes que, em parte, é responsável pelo efeito de reminiscência. / Abstract: Alice Munro stands out as a great short-story writer with texts that, elaborated in a new form, defy the genre qualification and are characterized by the open endings. It is in the counterpoint between realism, modernism and post-modernism that Alice Munro builds her narratives, a moment of transition and renewed conceptions related to the literary work that, expressed in her pieces, conjugates the contrasts by sophisticated techniques. The piece Lives of girls and women (2001), in prominence in this work, is classified as a novel by some critics - and the writer herself -, having, sometimes, the characteristics of a Bildungsroman. However, it is made of shortstories, fragmentation that favours the independence of each narrative, but that does not break definitively the notion of continuity, characteristic of the novel. It is this way of working with the short-story in the cited piece that the project in question studies, trying to verify how this situation happens inside the book structure and its meaning effects. It is also an aim of the study to identify, in the middle of this fragmentation, the maze of voices that, in part, is responsible for the reminiscence effect. / Mestre

Azoxystrobin (AZY), a systemic broad-spectrum fungicide, is applied on crops to control soil-borne pathogenic fungi. This study aimed to determine the effects of AZY on non-target plant species and Glomus intraradices Schenck & Smith, an arbuscular mycorrhizal fungus (AMF) associated with plants' roots. We hypothesized that AZY negatively affects AMF viability; and that, if the plants were dependent on this symbiosis, AZY exerts an indirect detrimental effect on plant growth. To test this, three mycotrophic (Phalaris arundinacea L., Solidago canadense L., Geum canadense Jacq.) and one non-mycotrophic (Chenopodium album L.) native plant species were subjected to five AZY doses with or without AMF. Plants were grown for 60 days in a greenhouse, in individual pots, (4 plants X 2 AMF X 5 AZY X 6 replicates), and mesocosms (1 mes. X 2 AMF X 5 AZY X 6 replicates), and harvested 30 days after spraying, and dry mass was taken. Fresh root samples were used for microscopic assessment of AMF colonization. The results from the individual pot experiment show that the effects of AZY on biomass varied across plant species. AZY led to a significant increase in shoot and root mass of P. arundinacea, and a decrease in shoot mass of AMF inoculated G. canadense. The presence of AMF resulted in a significant increase in root and shoot mass of P. arundinacea, and an increase in root mass of S. canadense and shoot mass of C. album. In the mesocosm experiment AZY did not have a significant effect on the measured parameters, although the presence of AMF significantly increased root, shoot, and total dry mass of G. canadense and P. arundinacea. Conversely, AMF significantly decreased shoot and total dry mass of S. canadense. The results suggest that both direct and indirect effects should be taken into account when assessing the impact of pesticides on non-target plant species.
