El carácter fronterizo de las identidades contemporáneas: el caso de Chiapas

The thesis or hypothesis of this paper is that the multiple connections of explicit and implicit life styles foster the construction of hybrid, multiple or complex identities. We mean by hybrid identities the confluence of multiple identifications in the personal biography. If the globalization and cultural diversity are the fundamental forms of global life, the mobility is its principal ingredient. We describe different cultural traits in Chiapas. Internet, migration to United States, or the North American Free Trade Agreement (NAFTA), between North America, Canada, and Mexico, were hybridized with the heterogeneity of identity (ethnic, linguistic, and religious). It is discussed the social and political consequences of the hybrid contemporary societies

O ensino-aprendizagem da física e da química: manuais escolares versus recursos digitais

Nesta dissertação investigamos o uso do manual escolar na sala de aula, em consonância com as mudanças das práticas pedagógicas resultantes da existência de novos recursos digitais agregados ao manual escolar, tais como o e-manual, os CD-ROM e DVDs e, as plataformas educacionais na Internet, em particular, a Escola Virtual, da Porto Editora. O leitmotiv da realização desta investigação é avaliar a utilização destes recursos, quer nas práticas pedagógicas inovadoras por parte dos docentes, quer na contribuição para melhorar a aprendizagem dos alunos. No sentido de melhor compreender e analisar o impacto da integração dos recursos digitais no ensino-aprendizagem, escolhemos os recursos da Porto Editora, visto tratar-se de um estudo de caso centrado numa escola que adotou estes recursos. A partir de um enquadramento metodológico que procura ultrapassar as dicotomias entre as abordagens quantitativas e as abordagens qualitativas, centramos o nosso estudo numa unidade didática, Astronomia, lecionada no 7º ano de escolaridade, na disciplina de Ciências Físico-Químicas. Com base num modelo heurístico, os dados recolhidos através de questionários a professores e alunos numa escola onde a investigadora estagiou, referente a este conteúdo, indicam que a utilização dos referidos recursos digitais no ensino-aprendizagem, fomentou a motivação para a realização de atividades propostas, facilitou a compreensão e a aprendizagem de conceitos e motivou os alunos para o estudo na disciplina de Ciências Físico-Químicas. Não podemos deixar de enfatizar a exploração do manual interativo, como um elemento extremamente inovador, e simultaneamente potenciador da disseminação de conhecimentos em espaços não convencionais de ensino, pela possibilidade de autoaprendizagem, respeitando as particularidades dos alunos. No entendimento de uma postura de abertura e de investigação permanente e, conscientes de que o ensino-aprendizagem engloba inúmeros fatores, apontamos alguns trajetos investigativos possíveis que poderão, eventualmente, despontar, a partir deste estudo. 

Innovative use of vodcast (Video-Podcast) to enrich learning experience in structures laboratory

Students may have difficulty in understanding some of the complex concepts which they have been taught in the general areas of science and engineering. Whilst practical work such as a laboratory based examination of the performance of structures has an important role in knowledge construction this does have some limitations. Blended learning supports different learning styles, hence further benefits knowledge building. This research involves an empirical study of how vodcasts (video-podcasts) can be used to enrich learning experience in the structural properties of materials laboratory of an undergraduate course. Students were given the opportunity of downloading and viewing the vodcasts on the theory before and after the experimental work. It is the choice of the students when (before or after, before and after) and how many times they would like to view the vodcasts. In blended learning, the combination of face-to-face teaching, vodcasts, printed materials, practical experiments, writing reports and instructors’ feedbacks benefits different learning styles of the learners. For the preparation of the practical, the students were informed about the availability of the vodcasts prior to the practical session. After the practical work, students submitted an individual laboratory report for the assessment of the structures laboratory. The data collection consisted of a questionnaire completed by the students, follow-up semi-structured interviews and the practical reports submitted by them for assessment. The results from the questionnaire were analysed quantitatively, whilst the data from the assessment reports were analysed qualitatively. The analysis shows that most of the students who have not fully grasped the theory after the practical, managed to gain the required knowledge by viewing the vodcasts. According to their feedbacks, the students felt that they have control over how to use the material and to view it as many times as they wish. Some students who have understood the theory may choose to view it once or not at all. Their understanding was demonstrated by their explanations in their reports, and was illustrated by the approach they took to explicate the results of their experimental work. The research findings are valuable to instructors who design, develop and deliver different types of blended learning, and are beneficial to learners who try different blended approaches. Recommendations were made on the role of the innovative application of vodcasts in the knowledge construction for structures laboratory and to guide future work in this area of research.

A comparison of space weather analysis techniques used to predict the arrival of the Earth-directed CME and its shockwave launched on 8 April 2010

The Earth-directed coronal mass ejection (CME) of 8 April 2010 provided an opportunity for space weather predictions from both established and developmental techniques to be made from near–real time data received from the SOHO and STEREO spacecraft; the STEREO spacecraft provide a unique view of Earth-directed events from outside the Sun-Earth line. Although the near–real time data transmitted by the STEREO Space Weather Beacon are significantly poorer in quality than the subsequently downlinked science data, the use of these data has the advantage that near–real time analysis is possible, allowing actual forecasts to be made. The fact that such forecasts cannot be biased by any prior knowledge of the actual arrival time at Earth provides an opportunity for an unbiased comparison between several established and developmental forecasting techniques. We conclude that for forecasts based on the STEREO coronagraph data, it is important to take account of the subsequent acceleration/deceleration of each CME through interaction with the solar wind, while predictions based on measurements of CMEs made by the STEREO Heliospheric Imagers would benefit from higher temporal and spatial resolution. Space weather forecasting tools must work with near–real time data; such data, when provided by science missions, is usually highly compressed and/or reduced in temporal/spatial resolution and may also have significant gaps in coverage, making such forecasts more challenging.

Modelling of surface identifying characteristics using Fourier series

Texture and small-scale surface details are widely recognised as playing an important role in the haptic identification of objects. In order to simulate realistic textures in haptic virtual environments, it has become increasingly necessary to identify a robust technique for modelling of surface profiles. This paper describes a method whereby Fourier series spectral analysis is employed in order to describe the measured surface profiles of several characteristic surfaces. The results presented suggest that a bandlimited Fourier series can be used to provide a realistic approximation to surface amplitude profiles.

Basic Income, Republican Freedom, and Effective Market Power

This article examines republican arguments for a basic income that turn on a right to exit the labour market. It gives criteria for the maintenance of republican freedom in markets, arguing that a right to exit or effective market power will guarantee republican freedom in markets. The article then considers whether a basic income is either sufficient or necessary to protect republican freedom both in labour markets and elsewhere. If a basic income is necessary to protect republican freedom in the labour market, I argue it is not sufficient to protect that freedom elsewhere. If citizens lack the means to maintain their republican freedom in the labour market, then there may be other spheres of life where they are vulnerable to subordination, whether or not they have a basic income. Some sociological evidence on cultural consumption patterns is presented.

Distance teacher education : Experiences from Dalarna University, Sweden

In 2003 the first distance teacher education started at Dalarna University in a small scale compared with today when a large part of the teacher education is distributed as distance education. From this point of view it seems important to ask the question: How can you become a successful distance student? This paper is based on a case study. Data were collected from earlier research reports, study registers and a group interview. The most important parameters appeared to be motivation, situation in life, discipline and experiences from earlier studies and/or work experience and good relations to other students and the university teachers.

Plano de carreira versus crescimento do indivíduo e eficácia das organizações - o caso Instituto Batista de Educação de Vitória (ES)

A temática aqui proposta tem por objetivo analisar até que ponto a implementação de um plano de carreira pode vir a ser um fator de crescimento do indivíduo e de maior eficácia no Instituto Batista de Educação de Vitória (ffiEV). Assim, no presente Estudo de Caso foram realizadas pesquisas bibliográficas e pesquisa de campo mediante aplicação de questionário (entrevistas focalizadas, semi-estruturadas) de forma a embasar conceitualmente a temática e com informações relevantes caracterizar a Instituição, para estabelecer a relação entre plano de carreira, plano de vida e a utilização do capital humano como um fator de crescimento do indivíduo e de maior eficácia organizacional. Os elementos que compõem o quadro de recursos humanos do ffiEV serão apresentados e interpretados sob um enfoque dialético compatível com as proposições de plano de carreira e plano de vida, dos autores elencados na bibliografia No transcorrer dessa dissertação serão contracenados os conceitos de plano de carreira e plano de vida que por um longo período de tempo e talvez ainda hoje, são pensados como não correlacionados. Isto acontece porque, para conseguirmos correlacionar estes conceitos e sistemas, necessitamos aprender a analisá-los de uma perspectiva macro. Neste ponto, pode-se juntar estes conceitos e entender as suas correlações. É claro que estes relacionamentos são complexos, o que é uma das razões pelas quais eles não são enxergados. Olhando para este quadro geral através do conceito plano de carreira/plano de vida, é fácil concluir que o ffiEV é um sistema complexo com subsistemas ativos (humano e técnico) e uma estrutura geral (estrutura). Esta estrutura irá prover meios com os quais os subsistemas irão interagir, e conseqüentemente prover diferentes possibilidades de interação. As interações entre os atores do sistema terão conseqüências que poderão ser medidas através de investigações quantitativas e qualitativas. Estas conseqüências são, por exemplo, qualidade, eficiência organizacional, lucro, satisfação com o trabalho, comprometimento com a organização, ou pode-se dizer de maneira mais geral que estas conseqüências são referentes à saúde do indivíduo e à saúde da organização. Este sistema complexo chamado ffiEV existe e interage em um sistema maior, chamado mercado, que por sua vez é parte de outro sistema, que é a sociedade. O ser humano é também um componente destes dois outros sistemas. Este, então, age e interage em ambientes distintos e correlacionados, que são a instituição (como funcionário), o mercado (como consumidor) e a sociedade (como membro). Por se constatar que o sistema humano em questão interage uma certa quantidade de horas exclusivamente ou quase exclusivamente com a instituição, e uma mesma ou maior quantidade de horas com a sociedade, então não podem ser excluídas realidades da vida de alguém, do seu trabalho na organização ou do seu convívio com família e amigos.
