Divining for meaning and searching for a female literary identity in Alice Munros Lives of girls and women and Margaret Laurences The diviners

Esta dissertação tem por objetivo investigar como Alice Munro e Margaret Laurence se apropriam de gêneros canônicos, especificamente do Bildungsroman e do Künstlerroman, para subvertê-los e representar versões diferentes do sujeito feminino através de romances de cunho autobiográfico escritos por mulheres. A investigação é focada em dois romances: Lives of Girls and Women (1971), escrito por Alice Munro, e The Diviners (1974), escrito por Margaret Laurence. No romance de Alice Munro, as estratégias de apagamento das fronteiras entre gêneros, a ideia de que perspectivas de realidade mudam de acordo com a experiência e a memória de cada indivíduo, como também a ênfase no desenvolvimento da protagonista enquanto pessoa e escritora, são assuntos amplamente discutidos. No romance de Margaret Laurence, a ênfase no aspecto subjetivo da memória, a desconstrução de estereótipos de gênero e a renegociação da representação do sujeito feminino para o alcance de uma identidade feminina autônoma na vida e na arte são os principais assuntos investigados. Em vista disso, esta dissertação visa mostrar como a representação da identidade feminina é redefinida por duas escritoras canadenses que se apropriaram de discursos dominantes para subvertê-los e, então, reescreverem suas histórias

A enfermagem no espelho: suas concepções sobre a profissão, a formação, a prática profissional e as especialidades

O objeto do presente estudo é o reflexo da enfermagem no espelho, a partir das concepções sobre as especializações em enfermagem e sobre a própria profissão, a formação e a prática profissional, conforme apresentadas na Revista Brasileira de Enfermagem, ano de 2003. Houve uma primeira fase exploratória, onde o trabalho de campo não se mostrou satisfatório, uma vez que não foi suficiente para responder às indagações ou fornecer as explicações sobre a atuação e as atribuições profissionais de enfermeiros com titulação de especialistas no mercado de trabalho. Por isso, partiu-se para um outro tipo de estudo, desta vez, descritivo, contemplando uma abordagem qualitativa por meio de uma revisão bibliográfica, baseada no método de análise de conteúdo. Desta forma, o estudo tem por objetivo geral analisar as imagens refletidas pela enfermagem ao olhar-se no espelho, a primeira a partir de um panorama geral da profissão e suas especialidades e, a segunda a partir das concepções que ela tem a respeito da própria profissão, da formação e da prática profissional, tal como são vistas na Revista Brasileira de Enfermagem, ano 2003. Os objetivos específicos são: descrever os principais pontos de vista encontrados sobre as características da profissão, sobre o processo de formação e sobre a prática profissional e contextualizar o panorama das especialidades à luz dos pontos de vista descritos. Dentre os principais resultados do estudo, destacamos a elaboração de um panorama geral da enfermagem no Brasil e as especialidades e de quatro categorias de análise: o que é a profissão de enfermagem; formação profissional da enfermagem; prática profissional da enfermagem e a enfermagem em processo de construção. A nós parece que a enfermagem tem apresentado dois reflexos diferentes neste espelho, as quais não se comunicam entre si. A primeira imagem refletida no espelho é a de uma enfermagem que busca definir especialidades da profissão voltadas para o aperfeiçoamento técnico, numa tentativa de se auto-afirmar no mercado de trabalho, que vem ficando cada vez mais específico e seletivo. A segunda imagem é a de uma enfermagem em busca de encontrar sua identidade enquanto ciência, e para isso, ela reflete, investiga e debate sobre o cuidado e sobre as teorias que sistematizam este cuidado. A questão é que estes dois reflexos apresentam fortes diferenças entre si, o que gera uma imagem distorcida para a profissão.

Determination of ethenzamide and acetoaminophen in quaternary powdered samples by near infrared spectroscopy and searching combination moving window partial least squares algorithm: effects of spectral resolution and signal-to-noise ratio

The present study reports an application of the searching combination moving window partial least squares (SCMWPLS) algorithm to the determination of ethenzamide and acetoaminophen in quaternary powdered samples by near infrared (NIR) spectroscopy. Another purpose of the study was to examine the instrumentation effects of spectral resolution and signal-to-noise ratio of the Buchi NIRLab N-200 FT-NIR spectrometer equipped with an InGaAs detector. The informative spectral intervals of NIR spectra of a series of quaternary powdered mixture samples were first located for ethenzamide and acetoaminophen by use of moving window partial least squares regression (MWPLSR). Then, these located spectral intervals were further optimised by SCMWPLS for subsequent partial least squares (PLS) model development. The improved results are attributed to both the less complex PLS models and to higher accuracy of predicted concentrations of ethenzamide and acetoaminophen in the optimised informative spectral intervals that are featured by NIR bands. At the same time, SCMWPLS is also demonstrated as a viable route for wavelength selection.

Genetically Generated Neural Networks II: Searching for an Optimal Representation

Genetic Algorithms (GAs) make use of an internal representation of a given system in order to perform optimization functions. The actual structural layout of this representation, called a genome, has a crucial impact on the outcome of the optimization process. The purpose of this paper is to study the effects of different internal representations in a GA, which generates neural networks. A second GA was used to optimize the genome structure. This structure produces an optimized system within a shorter time interval.

Optimal foraging strategies: Lévy walks balance searching and patch exploitation under a very broad range of conditions

While evidence for optimal random search patterns, known as Lévy walks, in empirical movement data is mounting for a growing list of taxa spanning motile cells to humans, there is still much debate concerning the theoretical generality of Lévy walk optimisation. Here, using a new and robust simulation environment, we investigate in the most detailed study to date (24×10(6) simulations) the foraging and search efficiencies of 2-D Lévy walks with a range of exponents, target resource distributions and several competing models. We find strong and comprehensive support for the predictions of the Lévy flight foraging hypothesis and in particular for the optimality of inverse square distributions of move step-lengths across a much broader range of resource densities and distributions than previously realised. Further support for the evolutionary advantage of Lévy walk movement patterns is provided by an investigation into the 'feast and famine' effect, with Lévy foragers in heterogeneous environments experiencing fewer long 'famines' than other types of searchers. Therefore overall, optimal Lévy foraging results in more predictable resources in unpredictable environments.

Hidden Gems: systematically searching electronic databases for research publications for social work and social care.

Context: Electronic bibliographic databases are a key source for professional publications about social work and community care more generally. This article describes and evaluates a method of identifying relevant articles as part of a systematic review of research evidence. Decision making about institutional and home care services for older people is used as an example. Method: Four databases (Social Science Citation Index, Medline, CINAHL, and Caredata) that abstract publications relevant to health and social services were searched systematically to identify relevant research studies. The items retrieved were appraised independently using a standard form developed for the purpose. The searches were compared in terms of sensitivity, precision, overlap between databases, and inter-rater reliability. Results: The search retrieved 525 articles, of which 276 were relevant. The four databases retrieved 55%, 41%, 19%, and 1% of the relevant articles respectively, achieving these sensitivities with precision levels of 54%, 48%, 84% and 94%. The databases retrieved 116, 73, 24 and 15 unique relevant articles respectively, showing the need to use a range of databases. Discussion: A general approach to creating a search to retrieve relevant research has been developed. The development of an international, indexed database dedicated to literature relevant to social services is a priority to enable progress in evidence-based policy and practice in social work. Editors and researchers should consider using structured abstracts in order to improve the retrieval and dissemination of research.

Searching for the IRA 'disappeared': Ground-penetrating radar investigation of a churchyard burial site, Northern Ireland

A search for the body of a victim of terrorist abduction and murder was made in a graveyard on the periphery of a major conurbation in Northern Ireland. The area is politically sensitive and the case of high profile. This required non-invasive, completely non-destructive and rapid assessment of the scene. A MALA RAMAC ground-penetrating radar system was used to achieve these objectives. Unprocessed and processed 400MHz data shows the presence of a collapse feature above and around a known 1970s burial with no similar collapse above the suspect location. In the saturated, clay-rich sediments of the site, 200MHz data offered no advantage over 400MHz data. Unprocessed 100MHz data shows a series of multiples in the known burial with no similar features in the suspect location. Processed 100MHz lines defined the shape of the collapse around the known burial to 2m depth, together with the geometry of the platform (1m depth) the gravedigger used in the 1970s to construct the site. In addition, processed 100MHz data showed both the dielectric contrast in and internal reflection geometry of the soil imported above the known grave. Thus the sequence, geometry, difference in infill and infill direction of the grave was reconstructed 30 years after burial. The suspect site showed no evidence of shallow or deep inhumation. Subsequently, the missing person������¢���¯���¿���½���¯���¿���½s body was found some distance from this site, vindicating the results and interpretation from ground-penetrating radar. The acquisition, processing, collapse feature and sequence stratigraphic interpretation of the known burial and empty (suspect) burial site may be useful proxies for other, similar investigations. GPR was used to evaluate this site within 3 hours of the survey commencing, using unprocessed data. An additional day of processing established that the suspect body did not reside here, which was counter to police and community intelligence.

Searching and planning: Young children's reasoning about past and future event sequences

Six experiments examined children's ability to make inferences using temporal order information. Children completed versions of a task involving a toy zoo; one version required reasoning about past events (search task) and the other required reasoning about future events (planning task). Children younger than 5 years failed both the search and the planning tasks, whereas 5-year-olds passed both (Experiments 1 and 2). However, when the number of events in the sequence was reduced (Experiment 3), 4-year-olds were successful on the search task but not the planning task. Planning difficulties persisted even when relevant cues were provided (Experiments 4 and 5). Experiment 6 showed that improved performance on the search task found in Experiment 3 was not due to the removal of response ambiguity.

Domain Bundle Boundaries in Single Crystal BaTiO3 Lamellae: Searching for Naturally Forming Dipole Flux-Closure / Quadrupole Chains

Naturally occurring boundaries between bundles of 90o stripe domains, which form in BaTiO3 lamellae on cooling through the Curie Temperature, have been characterised using both piezoresponse force microscopy (PFM) and scanning transmission electron microscopy (STEM). Detailed interpretation of the dipole configurations present at these boundaries (using data taken from PFM) shows that, in the vast majority of cases, they are composed of simple zigzag 180° domain walls. Topological information from STEM shows that, occasionally, domain bundle boundaries can support chains of dipole flux closure and quadrupole nanostructures, but these kinds of boundaries are comparatively rare; when such chains do exist, it is notable that singularities at the cores of the dipole structures are avoided. The symmetry of the boundary shows that diads and centres of inversion exist at positions where core singularities should have been expected.
