Developing a culturally-relevant genre-based writing course for distance learning
No full textLearners with seemingly adequate linguistic abilities sometimes write in ways that are
inappropriate in particular situations. This impacts on the intended communicative purpose,
and for exam takers, the outcome is underperformance. This paper outlines the development
and implementation of a short distance writing course that was designed to improve writing
through a genre-based approach to second language writing (K. Hyland, 2005) and evolved
using good non-native writing samples as exemplar texts (Tribble, 2005) to draw attention to
language, in this case for IELTS exam writing. A key element of the course was the submission of
multiple drafts, thus allowing a dialogue to develop, which in turn encouraged participants to
consider how to come closer to genre expectations of organization and structure as well as
improving the accuracy and sophistication of their texts
A politics of conversion: nihilism and love in Toni Morrison's fiction
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Letras.O estudo Uma Política de Conversão: Niilismo e Amor na Ficção de Toni Morrison começa com a idéia de que a Literatura Afro-Americana apresenta um sentido de auto-reflexividade e hibridismo, através do qual autobiografia dialoga com romance, o espiritual se funde com o político. A partir deste traço dialógico a auto-reflexividade é politicamente estabelecida entre niilismo e amor. Na política de conversão, o estudo analisa as formas como mulheres negras, individualmente ou em grupo, fogem da escravidão para a liberdade, avançam da individualidade para a coletividade, ou substituem niilismo por amor. Metodologicamente o estudo apresenta sete capítulos. O primeiro discute os aspectos dialógicos que ilustram as conexões entre narrativas espirituais, de escravos e ficção, entre espiritualidade e política. O segundo examina o diálogo entre a conversão, pregação pública e formação da comunidade em Diário e Experiências Religiosas de Lee. O capítulo sugere que ao afirmar espiritualidade e humanidade a narradora abre profundo espaço para a mulher negra reclamar direitos civis. O terceiro discute o diálogo no interior da política de conversão entre narrativa de escravos e ficção. Este diálogo lida com niilismo e amor em Incidentes de Jacobs e Amada, Sula e O Olho Mais Azul de Morrison. Para a análise de niilismo e amor valores individuais e coletivos são considerados em relação a cinco aspectos: ambiente e agente antagonistas, agente de apoio, propósito da personagem e resultado alcançado. É visível, no estudo, o apoio que certas mulheres recebem de suas comunidades para contra-atacar antagonistas. O apoio nem sempre resulta na superação do niilismo e, por isso, derrota temporária pode ocorrer antes que elas sejam reintegradas à comunidade, como acontece com Linda Brent. O quarto capítulo examina as fraquezas e as energias da política da conversão e a reintegração de Sethe Suggs à comunidade de Bluestone Road. O quinto avalia como a comunidade de Bottom tenta controlar a individualidade de Sula Peace e como um grupo de mulheres lideradas por Nel Wrights consegue resgatar o espírito de independência da heroína. O sexto mostra como a política da conversão das mulheres de Lorain é incapaz de garantir a saúde mental de Pecola Breedlove, mas consegue criar um papel mais consistente para o grupo. No sétimo, a conclusão examina da relação dialética entre niilismo e amor ou auto-amor nas experiências dos indivíduos e dos grupos. O estudo sugere que em Incidentes a busca de Linda Brent por liberdade envolve elementos de autodestruição e de autoempoderamento. Da mesma maneira, o estudo conclui que em Amada o amor que Sethe Suggs tem para as suas crianças mata a própria filha, enfatizando, assim, o desejo de livrá-la da escravidão. Igualmente em Sula, a individualidade de Sula Peace não apenas limita, mas também expande as experiências do grupo, levando-o à emancipação. Finalmente, em O Olho Mais Azul a luta de Pecola Breedlove por amor e beleza reflete auto-ódio ao mesmo tempo em que reconstrói a auto-apreciação de toda a comunidade
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

Discrete element method study of abrasion
No full textAbrasion is a surface breakage event where irregular surfaces of particles are removed. In other words, in milling it is the process which produces sphere like particles by comminuting asperities. Extensive experimental work has been performed to study abrasion events and their process parameters. Very few studies have used the discrete element method (DEM) to study the abrasion behavior of particles. In this regard, this paper reports on using DEM simulation to study the abrasion in a small scale tumbling mill environment. DEM simulations have been carried out for different test mills ranging in diameter from 0.2 m to 1.1 m and all of the mills have 0.2 m length. Each mill has square shaped lifters of 30 mm cross-section. The outcome of the simulation are evaluated to investigate the abrasion and milling parameters, like, force, different energy losses, collision frequency, power consumption. The DEM results are compared with experimental results performed at the JKMRC laboratory
Reflecting on the role of emotions in the PhD process
No full textThis research project examined the role of emotions in the PhD process through an exploratory, qualitative, self reflective study by six recent or current PhD candidates. Despite differences in the nature of the PhD fields of study, and in the personal backgrounds of the participants, a number of common themes were recognised. We developed an interactive workshop for postgraduate students in which participants were asked to reflect on their emotional experiences in their own studies. The combined information from these sources was used to suggest some strategies for management of negative emotions that may arise during the PhD process. Of critical importance is the multiple roles of the PhD supervisor in helping manage the negative emotions that most PhD students inevitably experience at some stage in their candidature. Most important, though, is the role of self reflection in identifying potential emotional problems and their solutions; a process we recommend to PhD candidates and supervisors

Extracting Boer-Mulders functions from p+D Drell-Yan processes
No full textWe extract the Boer- Mulders functions of valence and sea quarks in the proton from unpolarized p + D Drell- Yan data measured by the FNAL E866 Collaboration. Using these Boer- Mulders functions, we calculate the cos2 phi asymmetries in unpolarized pp Drell- Yan processes, both for the FNAL E866/ NuSea and the BNL Relativistic Heavy Ion Collider experiments. We also estimate the cos2 phi asymmetries in the unpolarized p (P) over bar Drell- Yan processes at GSI.Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)37ARTICLE5null7
Hamiltonian formulation of a collisionless reconnection model valid for high and low beta plasmas
No full textAn Effcient Implementation of the Ensemble Kalman Filter Based on Iterative Sherman Morrison Formula
No full textAbstractThis paper proposes an effcient implementation of the ensemble Kalman filter (EnKF) for the solution of largescale data assimilation problems. The implementation exploits the special structure of the covariance matrix and solves the analysis step by iteratively applying the Sherman Morrison formula. The iterative implementation leads to p savings in both memory and run time. The number of operations for the iterative method is O(nens2.nobs, while for p 3the standard implementation the cost is O nobs. The new implementation of the EnKF is tested using the Lorenz 96 model and shows a better performance than EnKF with the direct computation of the inverse
