Activity, work and employment: some reflections on a topic under debate

Since ten years ago, it is intensely thought of human work and employment in developed countries as a consequence of the deep changes on the productive system. In this chapter we analyze at first place the concept of work and its evolution, based on recent researches. In second place we review the notions of activity, work and employment and also the definition and measurement of unemployment, which is not a very old notion. The third part is about the work rol in human life and finally we study the different alternatives on activity and specific work contracts, proposals that nowadays replace the notion of "full employment" in France.

Reflections on vocational guidance and counselors' training in contexts of global change

Vocational guidance (V.G.) is currently facing both theoretical and methodological reconsiderations. This demands rethinking ethical and scientific assumptions, counselors' role and training. V.G. provides a space to receive information about oneself as well as about labor world and for the elaboration of projects for the future. Many guidance situations in teenagers and young adults are described in this paper, highlighting the main current emergent aspects. There was a remarkable protagonism of those seeking guidance and the reflective frame of the guidance. This frame prepares for the educational stage changes and also for occupational insertion working on aspects that widen autonomous choice and the development of social abilities and attitudes to carry out the vocational project and the development in work. Troubled sociocultural and economic transformations demand an on-going training on the part of counselors. To that end, possible fields of concern and subjects to be worked in said training are suggested.

Family diversity in social exclusion situations. Results and reflections on research, teaching and knowledge transfer activities

The purpose of this paper is to characterize the configurations of the families that live in contexts of social exclusion; provide conceptualizations of their operation mode; highlight the formative effects that neighborhood interdisciplinary practices with such families produce in the just graduated psychologists, included on the Extension Program. We wish to contribute to produce systematic knowledge that can account for such family configurations as potential receiver of integration policies. We are also interested on transferring the approach to diversity in the training of young professionals, in order not to be regarded as a deviation from ideal models, but as an expression of different strategies built by members of a community, to resolve children breeding and to bear their existences. This work is the result about reflections on productions inside a research fellowship: The complexities that takes the breeding in families who lives in a social exclusion situation; researches about breeding, carried out from signature Developmental Psychology II, and from de interdisciplinary work with psychologically assisted families in twelve suburbs of the city of La Plata (University Extension Program "Free Legal Offices" (Convention between Law and Social Sciences and Psychology Faculties, U.N.L.P.). From a qualitative methodology and an interdisciplinary participation, the results have arrive at the characterization and proposed conceptualizations of the included families and at the same time determine the benefits that brings with the work that articulates research and extension activities for the training of advanced students and young graduates.

Is the anti-trafficking framework really for the 'victims'? : reflections on Burmese victims of human trafficking and non-trafficked migrants in Thailand

Since the year 2000 when the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, human trafficking has been regarded as one of the egregious violations of human rights, and global efforts have been made to eradicate it. The anti-trafficking framework has multiple dimensions, and the way the anti-trafficking framework is constructed influences its impact on the victims and non-trafficked migrants. This paper will analyze the impact of the anti-trafficking framework on the experiences of Burmese victims and non-trafficked migrants in Thailand. I will question the conventional framework of anti-trafficking, and seek to construct a framework more appropriate for addressing victims' actual needs. In conclusion, the anti-trafficking framework should serve the best interest of the victim; still, it should not be one which might adversely affect the interest of the would-be victim who is not identified as a victim according to the law.

Some reflections on the IT challenges for a multilingual semantic web

Many attempts have been made to provide multilinguality to the Semantic Web, by means of annotation properties in Natural Language (NL), such as RDFs or SKOS labels, and other lexicon-ontology models, such as lemon, but there are still many issues to be solved if we want to have a truly accessible Multilingual Semantic Web (MSW). Reusability of monolingual resources (ontologies, lexicons, etc.), accessibility of multilingual resources hindered by many formats, reliability of ontological sources, disambiguation problems and multilingual presentation to the end user of all this information in NL can be mentioned as some of the most relevant problems. Unless this NL presentation is achieved, MSW will be restricted to the limits of IT experts, but even so, with great dissatisfaction and disenchantment

Transient acoustic response in car cabins with localization of reflections

Due to its small size and the restrictions on source and listener positions, the design of sound reproduction systems for car cabins is particularly cumbersome. In the present project the measurement of the impulse response between a single loudspeaker and a listener position, with special emphasis on the directional characteristics, will be examined. The propagation paths inside a car are very short, meaning that it is very difficult for the existing commercial measurement systems to resolve the different reflections arriving to the listener. This paper propose a first approach of an algorithm based on time difference of arrival along a measurement technique aiming at finding the reflections and their direction of arrival to the listener. To this end a circular microphone array at a known position is employed, along with Maximum-Length Sequences (MLS) measurement technique. The results are processed so as to extract the directional properties, demonstrate the physical limitations that can influence or prevent this detection in practice. Measurements were carried out in a free-field environment (anechoic chamber) making use of different panels closer around the microphone array. RESUMEN. El diseño de sistemas de reproducción de audio para cabinas de coche es especialmente complicado debido al reducido tamaño del espacio y las restricciones de los altavoces y posiciones de escucha de los ocupantes. En el presente proyecto, se examinan mediciones de la respuesta al impulso entre un altavoz y una posición de escucha con especial énfasis en las características direccionales. Los caminos de propagación de las ondas sonoras dentro de un coche son muy cortos, lo que hace difícil para los instrumentos de medida existentes en el mercado determinar las direcciones de llegada de las diferentes reflexiones que llegan a una posición de escucha. Este trabajo propone una primera aproximación de un algoritmo, basado en las diferencias temporales de llegada de una onda a diferentes puntos de medida, y una particular técnica de medida de la respuesta al impulso para obtener las direcciones de llegada de reflexiones a una posición de escucha. Para ello, se emplea una matriz circular de micrófonos en una posición conocida junto con la técnica de medida MLS (Maximum Length Sequence). Los resultados obtenidos son procesados para extraer la dirección de llegada de las reflexiones acústicas y encontrar las limitaciones que influyan en la detección de dichas reflexiones. Las mediciones se llevan a cabo en un entorno de campo libre y utilizando diferentes superficies reflectantes alrededor de la matriz de micrófonos.

Analysis and suppression of reflections in far-field antenna measurement ranges

This paper presents the analysis of the reflections in two kind of spherical far field ranges: one if the classical acquisition where the AUT is rotated and the second one corresponds to the systems where the AUT is fixed and the antenna probe is rotated. In large far field systems this is not possible, but this can be used to the measurement of small antennas, for instance, with the SATIMO StarGate system. In both cases, it is assumed that only one frequency is acquired and the results should be improved cut by cut, in order not to lose the advantages or far field measurements. Finally, some practical results are studied using measurements of one antenna in the outdoor far field facility of LIT INPE in Brazil.

Large-scale assessment of language proficiency: theoretical and pedagogical reflections on the use of multiple-choice tests

The new requirement placed on students in tertiary settings in Spain to demonstrate a B1 or a B2 proficiency level of English, in accordance with the Common European Framework of Reference for Languages (CEFRL), has led most Spanish universities to develop a program of certification or accreditation of the required level. The first part of this paper aims to provide a rationale for the type of test that has been developed at the Universidad Politécnica de Madrid for the accreditation of a B2 level, a multiple choice version, and to describe how it was constructed and validated. Then, in the second part of the paper, the results from its application to 924 students enrolled in different degree courses at a variety of schools and faculties at the university are analyzed based on a final test version item analysis. To conclude, some theoretical as well as practical conclusions about testing grammar that affect the teaching and learning process are drawn. RESUMEN. Las nuevas exigencias sobre niveles de competencia B1 y B2 en inglés según el Marco Común Europeo de Referencia para las Lenguas (MCERL) que se imponen sobre los estudiantes de grado y posgrado han llevado a la mayoría de las universidades españolas a desarrollar programas de acreditación o de certificación de estos niveles. La primera parte de este trabajo trata sobre las razones que fundamentan la elección de un tipo concreto de examen para la acreditación del nivel B2 de lengua inglesa en la Universidad Politécnica de Madrid. Se trata de un test de opción múltiple y en esta parte del trabajo se describe cómo fue diseñado y validado. En la segunda parte, se analizan los resultados de la aplicación del test a gran escala a un total de 924 estudiantes matriculados en varias escuelas y Facultades de la Universidad. Para terminar, se apuntan una serie de conclusiones teóricas y prácticas sobre la evaluación de la gramática y de qué modo influye en los procesos de enseñanza y aprendizaje.

Formação inicial de professores de química: o processo de reflexão orientada visando o desenvolvimento de práticas educativas no ensino médio

O Processo de Reflexão Orientada apresenta-se como uma nova proposta formativa, a qual pode contribuir para a formação inicial professores. Nesse processo, o futuro professor, mediado por um professor mais experiente, tem a oportunidade de elaborar e avaliar suas ideias sobre o ensino e a aprendizagem, suas metodologias e suas práticas de ensino, podendo clarificar e confrontar suas teorias pessoais. Neste sentido, este trabalho investigou as contribuições do PRO na atuação pedagógica de licenciandos em Química, visando um ensino por investigação e para a promoção da alfabetização científica no Ensino Médio. Para isso, mediados pela pesquisadora, os três licenciandos participantes da pesquisa elaboraram uma sequência de aulas e a desenvolveram em sala de aula, refletindo sobre suas concepções e práticas durante todo o processo envolvido. Diversas propostas de uma mesma sequência de aulas, sobre um mesmo conteúdo químico, foram elaborados pelos licenciandos, de forma a contemplar uma sequência investigativa e para promoção da AC. A última proposta foi aplicada em sala de aula. Os licenciandos avaliaram e refletiram sobre a sua prática em sala de aula e sobre os planos desenvolvidos, utilizando referenciais teóricos sobre ensino por investigação, AC e exigência cognitiva das questões. Para compreender a evolução dos licenciandos durante o PRO, a pesquisadora analisou os níveis investigativos dos elementos pedagógicos presentes nos planos elaborados e nas aulas ministradas por eles; o nível de AC dos planos e das aulas ministradas, bem como, o nível cognitivo das questões propostas nos planos e nas aulas. O processo reflexivo sobre a prática dos licenciandos é evidenciado por meio de categorias de análise e exemplificadas por trechos das transcrições dos encontros reflexivos realizados entre eles e a pesquisadora. As contribuições do grupo durante o processo também foram avaliadas. Os resultados mostram que os planos desenvolvidos pelos três licenciandos apresentaram evoluções na maioria dos tópicos avaliados, o que pode ser justificado pelas reflexões proporcionadas pelos encontros individuais e em grupo. No entanto, algumas dificuldades foram evidenciadas quanto a proposição da questão problema e de materiais para o levantamento das ideias prévias dos estudantes. A análise das aulas evidencia algumas dificuldades vivenciadas pelos licenciandos durante suas regências, como a sustentação da questão problema, bem como, das interações dialógicas. As reflexões realizadas entre a pesquisadora e os licenciandos, durante os encontros individuais, evidenciam momentos relevantes para a formação inicial, visto que os futuros professores expunham suas concepções, anseios e dilemas. Os encontros reflexivos em grupo também evidenciam contribuições, o que possibilitou ao grupo socializar, confrontar e compartilhar suas ideias e experiências. Esta pesquisa também mostra a importância do papel do mediador, já que a confiança dos licenciandos pela pesquisadora parece ter contribuído para o comprometimento deles durante o processo. Assim, o PRO vivenciado pelos licenciandos parece ter contribuído para eles desenvolverem uma postura crítica com relação à prática docente. Ao elaborar os planejamentos e avaliar suas ações, baseados em referenciais teóricos, puderam construir novas ideias sobre o processo de ensino e de aprendizagem em Química.
