"Enseigner les sciences": un espace numérique d'échange et de formation concernant l'enseignement des sciences à l'école primaire

Cela fait maintenant plus de 10 ans que les premiers dispositifs de e-learning ont vu le jour, que ce soit pour la formation continue ou pour la formation initiale. Dans un premier temps, le recours aux technologies n’a consisté qu’à publier sur Internet l’ensemble des ressources ainsi que le cours, sous forme de texte, dispensé par l’enseignant. Puis, grâce à l’évolution des technologies, de nouvelles possibilités ont vu le jour : la mise en ligne de documents audios, de vidéos, et plus récemment, la mise en place d’espaces numériques de travail permettant à l’enseignant, comme à tous les participants, d’y placer des documents et des commentaires. L’apparition des wikis a permis de voir apparaître de nouvelles formes de e-learning, basés sur la collaboration. Depuis quelques mois, l’explosion des réseaux sociaux, facebook pour le plus célèbre, permet d’envisager de nouveaux dispositifs d’apprentissage interconnectant cours en présentiel et travail à distance

Lideranças transformacional, transacional e laissez-faire : um estudo de caso

O presente trabalho é uma investigação quantitativa que se propõe relacionar vários níveis de liderança e diferentes tipos de liderança nos estabelecimentos do 1.º ciclo de um agrupamento de escolas, através do levantamento e análise das perceções dos professores que aí exercem funções. O instrumento de recolha de dados que utilizámos foi o Multifactor Leadership Questionnaire (MLQ) da autoria de Avolio e Bass (2004). O objetivo primordial foi aferir a incidência de comportamentos de liderança transformacional, transacional e laissez-faire num agrupamento de escolas, de forma a contribuir para a discussão e reflexão acerca das lideranças em contexto escolar. As principais conclusões que extraímos deste estudo foram que existe uma liderança vincada na nossa amostra, predominantemente Transformacional. Para além disso, verificámos que não foram percecionados nos líderes comportamentos característicos da Liderança Laissez-Faire.

Influência da liderança no comprometimento organizacional mediada pela satisfação com o líder

Na presente investigação procura-se descobrir qual a influência dos estilos de Liderança Transformacional e Transacional, propostos por Bass (1985), no Modelo das Três Componentes, proposto por Meyer e Allen (1991). Procura-se, ainda, descobrir se esta relação é mediada pela Satisfação com a Liderança, desdobrada entre a faceta Relações Humanas e a faceta Técnica, conforme Weiss, Dawis, England e Lofquist (1967). Foi aplicado um questionário a uma amostra de conveniência de 102 participantes de diversas empresas. As principais conclusões são que os estilos de Liderança determinam o Comprometimento Organizacional, e a Satisfação com o Líder tem uma relação de mediação entre os estilos de Liderança e o Comprometimento Organizacional. São, também, discutidas as implicações teóricas e práticas dos resultados.

Flow e os fenómenos de mentoria e liderança em indústrias de injeção de plásticos da Marinha Grande

Este estudo procura investigar possíveis associações entre as experiências de flow e os fenómenos de mentoria e liderança. Procura-se identificar as características e benefícios de experiências de flow e de relações de mentoria e liderança, percebidos pelos colaboradores de quatro empresas de Injeção de Plásticos da Marinha Grande. Identificam-se as funções de mentoria, os estilos de liderança transacional, transformacional e servidora e os componentes de flow entre estes colaboradores. Para a medição dos estilos de liderança foram utilizados os instrumentos desenvolvidos por Avolio e Bass (2004) e Dennis (2004). Para as funções das relações de mentoria, definidas por Ragins e Kram (2007), o instrumento desenvolvido por Noe (1988). Para os componentes observados em experiências de flow, o instrumento desenvolvido por Jackson e Ecklund (2002). Apoiado nos instrumentos referidos foi aplicado um questionário na recolha dos dados para este estudo. Foram encontradas influências moderadas e fortes entre os estilos de liderança, as funções de mentoria e os componentes de uma experiência de flow.

Características de liderazgo de los gerentes de la generación “baby boomers” y propuesta de plan de mejora de toma de decisiones estratégicas y eficacia, caso de estudio Global Engineering S.A.

El presente documento analiza las características de liderazgo de los gerentes “baby boomers” de la empresa transnacional Global Engineering S.A., que tiene oficinas en España, Cuba, Venezuela y Ecuador. Esta investigación se realiza sobre la premisa que los Gerentes de las cuatro oficinas pertenecen a la generación de los baby boomers, por lo se presenta la hipótesis de que, al pertenecer a una misma generación las características de liderazgo son similares. Los objetivos de la presente investigación, fueron el identificar las características de liderazgo de los gerentes, analizarlas, verificar si son eficaces, identificar las oportunidades de mejora y presentar un plan de mejora para la organización. Al presente estudio se lo define como exploratorio, descriptivo y correlacional, se utiliza como herramienta principal para la investigación el MLQ 5X versión corta creado por Bass y Avolio y adaptado por Vega y Zabala, se lo aplica a las cuatro oficinas de la empresa tanto a los gerentes como a los seguidores. Para la comprobación de la hipótesis, se utilizó la prueba t de Student, para establecer valores máximos y mínimos de los promedios de las características de liderazgo, para de esa manera conocer si los Gerentes de cada oficina tienen las mismas características, también se promediaron los valores resultantes de cada estilo de liderazgo para conocer si son eficaces para la realidad de la organización. Como herramienta para la mejora de toma de decisiones estratégica, se presenta el Cuadro de Mando integral, se establecen los objetivos principales para las perspectivas y se señalan los pasos de cómo debe ser el proceso de implementación del plan de coaching gerencial para la organización. De la investigación realizada se concluye que las características de liderazgo de los gerentes de la organización no se relacionan directamente con la generación a la que pertenecen, sino, dependen más del entorno, la situación y de los seguidores. Se recomienda la implementación del Cuadro de Mando Integral para mejorar la toma de decisiones estratégicas, haciendo énfasis en la propuesta de valor de implementar un plan de coaching gerencial para los gerentes de las distintas oficinas para así mejorar la eficacia de la organización.

Insights into processes and deposits of hazardous vulcanian explosions at Soufrière Hills Volcano during 2008 and 2009 (Montserrat, West Indies)

During the Soufrière Hills eruption, vulcanian explosions have generally occurred 1) in episodic cycles; 2) isolated during pauses in extrusion, and 3) after major collapses of the dome. In a different eruptive context, significant vulcanian explosions occurred on 29 July 2008, 3 December 2008, and 3 January 2009. Deposits are pumiceous except for the 3 December event. We reconstructed the dispersal pattern of the deposits and their textural characteristics to evaluate erupted volume and vesicularity of the magma at fragmentation. We discuss the implications of these explosions in terms of eruptive processes and chronology, and the hazards posed by their sudden and often unheralded occurrence. We suggest that overpressurization of the conduit can develop over time-scales of months to weeks by a process of self-sealing of conduit walls and/or the cooling dome by silica polymorphs. This work provides new insights for understanding the generation of hazardous vulcanian explosions at andesitic volcanoes.

A Guide to Office Clerical Time Standards

A Guide to Office Clerical Time Standards is an instructional performance piece based on a corporate manual from 1960. The pamphlet is focused on the time necessary for the accomplishment of minute labour procedures in the office, from the depressing and releasing of typewriter keys to the opening and closing of filing cabinet drawers. In the performance, seven costumed performers represent the different levels of management and employment while performing the actions described in the guide, accompanied by a live musical score. There has been much discussion of the changes to work in the west following the decline of post-Fordist service sector jobs. These increasingly emphasise the specificity of employees’ knowledge and cognitive skill. However, this greater flexibility and creativity at work has been accompanied by an opposite trajectory. The proletarisation of white collar work has given rise to more bureaucracy, target assessment and control for workers in previously looser creative professions, from academia to the arts. The midcentury office is the meeting point of these cultures, where the assembly line efficiency management of the factory meets the quantifying control of the knowledge economy. A Guide to Office Clerical Time Standards explores the survival of one regime into its successor following the lines of combined and uneven development that have turned the emancipatory promise of immaterial labour into the perma-temp hell of the cognitariat. The movement is accompanied by a score of guitar, bass and drums, the componenets of the rock ‘n’ roll music that rose from the car factories of the motor city and the cotton fields of the southern states to represent the same junction of expression and control.

The effects of stocking density in physiological parameters and growth of the endangered teleost species piabanha, Brycon insignis (Steindachner, 1877)

This study investigated the effects of stocking density on the growth and fatty acid (FA) of Brycon insignis metabolism. Fingerlings (360) were distributed into eight ponds at two stocking densities (105 and 210 g/m(3)). The analysis of growth showed that the condition factor (K) and the coefficient of variation (CV) for body mass were not affected by stocking density. However, final body mass and length, specific growth rate (SGR), and weight gain (WG) were higher in the low stocking density group, which also presented a higher feed efficiency (FE) and survival (S). By contrast, muscle protein levels were higher in the high stocking density group. The plasma and muscle lipid content were not affected by stocking density, but fish reared at lower stocking density presented higher lipid concentration in the liver, with no differences in hepatosomatic index values. Even with the differences observed in metabolic and growth parameters, plasma cortisol was not affected by stocking density. The FA profile in the muscle and liver neutral fraction were not affected by stocking density, but the FA in the polar fractions differed between the two stocking densities. In the liver, total polyunsaturated fatty acids (PUFA) and PUFA n - 3 increased in higher stocking density, mainly due to an increase in docosahexaenoic acid (DHA). In addition, PUFA n - 6 were also increased in the higher stocking density group, mainly due to an increase in arachidonic acid (AA) and docosadienoic acid (22:2n - 6). In the muscle polar fraction, the saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) decreased in the animals from the higher stocking density group, and this reduction was compensated by an increase in PUFA n - 3 and PUFA n - 6, mainly the FA with 20-22 carbons (20:4n - 6: 22:4:n - 6; 22:5n - 6, 22:5n - 3, and 22:6n - 3). A different profile was observed for the C18 PUFAs, mainly 18:2n - 6 and 18:4n - 6, which were higher in the lower density stocking group. The data suggest that when living in high stocking density, B. insignis differentially utilizes the hepatic lipids as energy source and remodels the membrane fatty acids, with higher amounts of DHA in the polar muscle fraction compensated for by a decrease in MUFA. The zootechnical and physiological indices reveal that the lower stocking density group achieve overall better performance. (C) 2010 Elsevier B.V. All rights reserved.

Fatty acids as trophic biomarkers in vitellogenic females in an impounded tropical river

Fatty acids have been used in marine biogeochemistry as food chain biomarkers, but in freshwater these studies are rare. In order to evaluate the fatty acid potential as biomarkers in freshwater, their profile was analyzed during vitellogenesis in two fish species, in both waterfall and reservoir environments of the Paraiba do Sul River Basin. Detrivorous Hypostomus affinis and omnivorous Geophagus brasiliensis seem to elongate and desaturate polyunsaturated fatty acids (PUFA) and transfer them to the ovaries` phospholipids. Waterfall Geophagus brasiliensis have more highly unsaturated fatty acids in the liver, but in the reservoir, accumulation mainly occurs in muscle and ovary triglycerides, suggesting trophic opportunism and a plasticity during vitellogenesis. In Hypostomus affinis, PUFA alteration occurs only in the reservoir, suggesting a high phytoplankton occurrence. Eutrophication and water speed is reflected in Hypostomus affinis ovaries by higher PUFAn3 and bacterial fatty acids. As in marine environments, analysis of mono- and polyunsaturated fatty acids during vitellogenesis can be used as a tool in food chain studies in freshwater.
