Speak Good English Movement in Singapore : Reactions in Social and Traditional Media

The first Speak Good English Movement, SGEM, took place in 2000, and has been organized annually ever since. Speaking a “standard” form of English is considered to bring increased personal power. However, the SGEM wants the Singaporeans to use “standard” English in their private life as well. A decade after the beginning of the campaign, a Speak Good Singlish Movement was started. Based on studies of language and identity, it is understandable why some Singaporeans might feel the SGEM threatens their identity. However, the reactions towards the campaign are mainly positive. For the purposes of this analysis, Twitter messages, Facebook pages, and newspaper articles from The Straits Times were collected. The SGEM has hailed both direct and indirect praise and criticism in both social and traditional media: Five newspaper articles praise the campaign while five criticize it; the results are nine and seven respectively for social media. This thesis looks at reactions towards the SGEM in both social and traditional media, analyzes how these reactions might relate to the ideas of the power of language, its variety and the relation of language and identity.

Wind farm construction impacts reindeer migration and movement corridors

Over the last decade, we have seen a massive increase in the construction of wind farms in northern Fennoscandia. Wind farms comprising hundreds of wind turbines are being built, with little knowledge of the possible cumulative adverse effects on the habitat use and migration of semi-domesticated free-ranging reindeer. We assessed how reindeer responded to wind farm construction in an already fragmented landscape, with specific reference to the effects on use of movement corridors and reindeer habitat selection. We used GPS-data from reindeer during calving and post-calving in the MalAyen reindeer herding community in Sweden. We analysed data from the pre-development years compared to the construction years of two relatively small wind farms. During construction of the wind farms, use of original migration routes and movement corridors within 2 km of development declined by 76 %. This decline in use corresponded to an increase in activity of the reindeer measured by increased step lengths within 0-5 km. The step length was highest nearest the development and declining with distance, as animals moved towards migration corridors and turned around or were observed in holding patterns while not crossing. During construction, reindeer avoided the wind farms at both regional and landscape scale of selection. The combined construction activities associated with even a few wind turbines combined with power lines and roads in or close to central movement corridors caused a reduction in the use of such corridors and grazing habitat and increased the fragmentation of the reindeer calving ranges.

The Movement of the Gastrop Littorina Littorea in the Intertidal Zone during the Onset of Winter

The movement of the snail Littorina littoreaon the North Atlantic coast is poorly understood. Most research has concentrated on the vertical distribution of the snail, and suggests that it prefers the low intertidal zone where its food source is most plentiful. In the winter, this distribution is reinforced by a documented seaward migration of snails from the high intertidal zone in response to falling temperatures. From October 14, 2006 to January 22, 2007, I examined the individual movements and recovery of snails in response to the onset of winter. I proposed that falling water and air temperatures drive the majority of snail movement within the intertidal zone, and that water temperature had the greater effect. I also examined the possibility that, in addition to a seaward migration, winter weather patterns in the Gulf of Maine and their effect on the ocean may encourage the wintertime vertical distribution of snails. Finally, I examined the possibility that populations of snails in the comparatively inhospitable high intertidal zone may endure the winter if given access to proper resources.

Oxford movement: its themes and their significance

In retrospective, the Oxford movement of nineteenth century England provides one with an interesting study of the struggles between the spiritual and secular worlds. However, repeated abstraction in an interpretation of its significance has tended to distort accurate understanding of its historical development. Often this also has resulted n a misinterpretation of the nature of its major themes and their significance to the world. For these reasons, this study has attempted to describe the origin, maturity, and dissolution of the series of events which strictly speaking may be considered to be the Oxford movement. In conclusion, liberty has been taken to comment on the nature of the Movement's themes and their significance in their own age and to man today.

Microinfiltração cervical imediata de dois sistemas adesivos em restaurações ocluso-proximais de resina composta em molares decíduos : estudo in vitro

O objetivo deste estudo foi de avaliar in vitro a microinfiltração cervical imediata em restaurações ocluso-proximais de resina composta, onde foram utilizados dois sistemas adesivos (Scotchbond Multi Purpose - 3M; Clearfil Mega Bond - Kuraray) através de uma técnica de baixa intensidade de luz polimerizável. Em cada um dos 11 molares decíduos foram confeccionados dois preparos cavitários ocluso-proximais padronizados (um ocluso-mesial e outro ocluso-distal), com o auxílio de uma ponta diamantada cilíndrica de extremidade plana n°2094, (KG Sorensen), fixada a uma caneta de alta rotação sob refrigeração ar/água. Os sistemas adesivos foram aplicados seguindo as instruções do fabricante, um na cavidade ocluso-mesial e outro na ocluso distal, sendo inserida, posteriormente, uma resina composta híbrida (Z250 - 3M) pela técnica incremental LUTZ (1986). O primeiro incremento foi inserido na parede cervical da caixa proximal (sentido horizontal) e fotopolimerizado (fotopolimerizador VIPTM - Bisco) a uma intensidade de 100 mW/cm2 por 60 segundos. Dois outros incrementos foram inseridos diagonalmente na porção vestibular e lingual/palatina, a uma intensidade de 200 mW/cm2, também pelo tempo de 60 segundos. As restaurações foram submetidas a acabamento e polimento com o auxílio de um bisturi lâmina n°12 e com discos Sof-lex Pop-on (3M). Após o acabamento, foi realizada a impermeabilização, em seguida os dentes foram imersos em solução azul de metileno a 0,5% por um período de 24 horas, sendo posteriormente seccionados longitudinalmente no sentido mésio-distal para avaliação da penetração do corante, usando para tal o estereo-microscópio. Os resultados foram submetidos à análise estatística através dos testes Qui-quadrado e o teste não-paramétrico U de Mann-Whitney. Os resultados demonstraram não haver diferença estatisticamente significante entre os dois sistemas adesivos testados, podendo-se concluir que a utilização deste protocolo restaurador de cavidades ocluso-proximais com resina composta em molares decíduos resultou em baixos níveis de microinfiltração cervical imediata.

In search of academic identity : physical education, sport science and the field of human movement studies

This thesis addresses the problem of the academic identity of the area traditionally referred to as physical education. The study is a critical examination of the argu ments for the justi cation of this area as an autonomous branch of knowledge. The investigation concentrates on a selected number of arguments. The data collection comprised articles books and proceedings of conferences. The preliminary assessment of these materials resulted in a classi cation of the arguments into three groups. The rst group comprises the arguments in favour of physical education as an academic discipline. The second includes the arguments supporting a science of sport. The third consists of the arguments in favour of to a eld of human movement study. The examination of these arguments produced the following results. (a) The area of physical education does not satisfy the conditions presupposed by the de nition of academic discipline. This is so because the area does not form an integrated system of scienti c theories. (b) The same di culty emerges from the examination of the ar guments for sport science. There is no science of sport because there is no integrated system of scienti c theories related to sport. (c) The arguments in favour of a eld of study yielded more productive results. However di culties arise from the de nition of human movement. The analysis of this concept showed that its limits are not well demarcated. This makes it problematic to take human movement as the focus of a eld of studies. These aspects led to the conclusion that such things as an academic discipline of physical education sport science and eld of human movement studies do not exist. At least there are not such things in the sense of autonomous branches of knowledge. This does not imply that a more integrated inquiry based on several disciplines is not possible and desirable. This would enable someone entering phys ical education to nd a more organised structure of knowledge with some generally accepted problem situations procedures and theories on which to base professional practice.

Racial discrimination in Brazil: interviews with leaders of the black movement

Racism in Brazil has some specificities when compared to other countries, for, differently from, for instance, South Africa and the United States, Brazilian Constitutions, ever since the Independence (1822), have never distinguished the citizens according to race or color. Furthermore, since the mid-1900s, Afro-Brazilian cultural manifestations, such as, for example, samba and capoeira, started to be valued as a part of our “national identity”. These specificities make race relations in Brazilian society a much more complex issue. This paper is focused on selected parts of interviews that deal with the nature of racial discrimination in Brazil, extracted from interviews with leaders of the black movement produced within the scope of the project “The History of Black Movement in Brazil: organization of a collection of Oral History Interviews”, developed by CPDOC, Getulio Vargas Foundation (Rio de Janeiro). These “histories within history”, as told by our interviewees, may be transformed into images that will be able to condense a given reality, thus allowing us to evaluate the gains obtained by oral history methodology.

Correlação entre achados colposcópicos e diagnóstico histológico segundo a Classificação Colposcópica da Federação Internacional de Patologia Cervical e Colposcopia de 2002

Objetivo: Avaliar a acurácia da colposcopia utilizando a Classificação Colposcópica Internacional de 2002. Métodos: 3040 pacientes de população geral foram rastreadas para patologia cervical através de exame citopatológico, captura híbrida para HPV de alto risco e inspeção cervical. As colposcopias que resultaram em biópsia (n=468) executadas no rastreamento e acompanhamento destas pacientes foram gravadas, revistas por dois colposcopistas cegados e incluídas para análise. Resultados: Os observadores apresentaram excelente concordância (Kappa=0.843) no relato dos achados pela nova nomenclatura. A colposcopia apresentou sensibilidade de 86% e especificidade de 30.3% em diferenciar colo normal de colo anormal (LSIL, HSIL ou carcinoma); quando a colposcopia objetivava diferenciar colo normal ou LSIL de HSIL ou carcinoma, apresentou sensibilidade de 61.1% e especificidade de 94.4%. Os achados colposcópicos classificados como “maiores” pela nova classificação apresentaram valores preditivos positivos elevados para HSIL. Presença do achado colposcópico na zona de transformação e tamanho da lesão estavam associados a HSIL. Bordas externas definidas, associação de múltiplos achados distintos e presença de zona iodo negativa não estavam relacionados à gravidade das lesões. Conclusão: A colposcopia utilizando a Classificação Internacional de 2002 mostra-se um bom método de rastreamento, mas como método diagnóstico apresenta falhas, não podendo substituir a avaliação histológica. A categorização em achados colposcópicos “maiores” e “menores” apresentada pela nova classificação é adequada. Na realização da colposcopia, é importante também que a lesão seja situada em relação à zona de transformação e que seu tamanho seja indicado, já que estes foram fatores associados a lesões de alto grau.

Avaliação dos efeitos na musculatura cervical do desempenho de dois protótipos de facas de corte de frango através da eletromiografia sensitiva

Este estudo apresenta o método utilizado e os resultados obtidos na avaliação dos efeitos, na musculatura cervical, de duas facas de corte de frango, de mesma forma e tamanho com cabos confeccionados com dois materiais diferentes (emborrachado, ou SOFT e de polipropileno ou PP). A comparação foi feita com base nos resultados da eletromiografia sensitiva (Myovision) da coluna cervical de dez funcionários voluntários de uma empresa de processamento de aves no Rio Grande do Sul. O protótipo de cabo SOFT mostrou uma menor tensão muscular na coluna cervical em comparação com o protótipo com cabo de polipropileno, o que pode impactar na sensação de maior conforto de manuseio da faca com cabo SOFT.
