Análise das práticas e dos comportamentos de liderança dos alunos da Universidade da Madeira

Esta investigação, de carácter quantitativo, pretende descrever e analisar as práticas e os comportamentos de liderança dos alunos da Universidade da Madeira. Na recolha de dados foi utilizado o Student Leadership Practices Inventory (SLPI), um instrumento de 30 itens, desenvolvido por Kouzes e Posner (2006b), que avalia as práticas de liderança em cinco domínios. O questionário foi administrado por correio electrónico, durante o mês de Fevereiro de 2009, a uma amostra aleatória que incluiu 208 indivíduos. Os dados recolhidos foram tratados e analisados com recurso ao software estatístico SPSS 16.0 (Statistical Package for Social Sciences). A análise dos resultados indica que a prática de liderança utilizada pelo maior número de alunos da Universidade da Madeira é “habilitar a agir”. Verificou-se, ainda, que existem diferenças significativas entre os sexos nesta mesma prática de liderança, sendo os alunos do sexo feminino os que utilizam com maior frequência esta prática de liderança. Por outro lado, provou-se não existirem diferenças significativas na frequência de utilização das práticas “modelar caminho”, “inspirar uma visão partilhada”, “desafiar o processo” e “encorajar a vontade” quanto à idade, quanto ao exercício de uma actividade profissional e em relação ao facto do aluno estar ou não relacionado com uma organização.

Desenvolvimento do currículo do 4º ano de escolaridade: análise da utilização de uma plataforma de e-learning em contexto escolar

Partindo de um sentido de inovação pedagógica assente numa concepção de clara ruptura com abordagens pedagógicas tradicionalistas ligadas a uma certa perspectiva transmissiva/reprodutiva do saber, o presente trabalho de investigação analisa a utilização, em contexto curricular escolar, de uma plataforma de e-learning, considerando um enquadramento referencial de natureza construtivista, no qual, o aluno possa assumir um papel central e activo, na criação do seu próprio conhecimento. Consistindo numa abordagem de natureza qualitativa, o estudo de caso apresentado releva um paradigma interpretativo decorrente da análise da utilização, pelos alunos, de uma turma do 4º Ano de escolaridade, da plataforma de e-learning ―Escola Virtual™‖. Para tal intento, a diversidade de técnicas de recolha de dados — observação participante, entrevistas , e análise documental — ao permitirem uma triangulação dos mesmos, fundamentam um aprofundado sentido de comprensão do fenómeno analisado. Deste modo, a investigação centra-se em 3 componentes referenciais: Componente Pedagógica, Componente de Conteúdos e Componente de Interface. Os resultados obtidos revelam que, no âmbito da primeira componente, surgem especialmente facilitados os processos colaborativos entre os alunos, embora num contexto de interacção presencial e com carácter essencialmente pontual; a actuação docente, mantendo o seu carácter imprescindível, adquire uma dimensão de maior proximidade e orientação dos alunos enquanto, por seu turno, o nível motivacional dos alunos é estimulado, focalizando o aluno nas tarefas de aprendizagem. A natureza do feedback presente, no entanto, revelou-se um factor com efeitos prejudiciais para os processos de reflexão e metacognição dos alunos. No respeitante aos conteúdos, foi evidente alguma ligeireza e fragilidade de concepção em muitos deles, comprovada por uma quantidade expressiva de erros e lapsos de diversa natureza; enquanto que a natureza pré-formatada dos conteúdos — estruturando-os em ―Objectos de Aprendizagem‖ — limitou significativamente a possibilidade de desenvolvimento de procressos activos e criativos por parte do aluno, bem como, anulando a capacidade de abordagem de competências de natureza prática previstas no Programa Nacional do Ensino Básico. Por fim, o interface que, embora caracterizando-se pela sua intuitividade e simplicidade, suporta um limitado grau de controlo, pelos alunos, sobre os fluxos interactivos, reduzidos às suas expressões mais elementares. No seu aspecto global podemos considerar que, num contexto curricular escolar, a plataforma ―Escola Virtual‖ não se constitui como uma ferramenta de aprendizagem capaz de se enquadrar num paradigma de inovação pedagógica congruente com o sentido atrás defendido,não obstante possamos entender, que a mesma, constitua uma potencial mais-valia no âmbito da consolidação e testagem de conhecimentos préviamente adquiridos.

Desenvolvimento de metodologias analíticas alternativas por cromatografia gasosa para análise de biodiesel

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Fonte de energia alternativa: um estudo sobre a percepção ambiental, social e econômica do biodiesel com docentes do Centro de Tecnologia do gás da cidade de Natal RN

Meaning fuel and renewal energy source s derivative additives, the term biodiesel exists in Brazil since 1980, when it was signed its first patent by Expedito Parente. Since then, its importance has grown gradually due to the worsening of the ambient problems, since its use has became a highly promising alternative to the pollution decrease, as in the carbon dioxide issue as with the smoke and sulfur oxide. In Brazil, it was created the National Program of Production, whose objective is to insert the new product in the country s energy matrix, strengthening the economy and creating new employment opportunities, being an important product to the national energetic independence, since Brazil still imports diesel to its domestic consumption. This study aims to identify the ambient, social and economic perception of the teachers from the Technology Center of Natal city (CTGÁS-RN) to the biodiesel. For that, it was used a questionnaire closed questions, organized in the likart scale, directed to the tree spheres of the research analysis, the biodiesel and its social, ambient and economic nuances, totaling 31 questionnaires full answered. In its objectives, the research was descriptive and in its approach it was qualitative. To the data analysis it was used statistical tools (Statistic software, 6.1 version and Microsoft Excel 2003). The research revealed the predominance of the ambient aspect in the sight of the teachers, followed by the social ones. The economic factors represent a minor percentage in the analysis when compared to other

Do dizer teórico às transposições didáticas: por um exercício da contrapalavra no ensino de língua escrita no PROJOVEM

This present work is going to show some results developed in the Master Degree research and the Post Graduation project in Language studies (PPgEL) at UFRN, under the orientation of Professor Maria da Penha Casado Alves. This research has questions showed by the Programa Nacional de Inclusão de Jovens PROJOVEM. Concerned to methodology, the research is based on Applied Linguistics and it is qualitative and documental. The corpus of the research are the Manual de Orientações Gerais and the Guias de Estudo. The documents that were used for the research were Guide for general orientation and the Study Guides.The Manual de Orientações Gerais was chosen because is focused on the teacher and the Guias de Estudo was chosen because are focused on the students. The discussions and analysis were based on Bakhtin (1997; 2003), for his studies about the language in a dialogical point of view, Faraco (2001 and 2008) and Suassuna (2006) for their discussions about the Portuguese Language and Geraldi (1997; 2005 and 2006) and Antunes (2003) for their orientation and discussions about the teaching process of the written language. The analysis made in the Reference Topics point that however the program proposes a kind of rupture with the traditional way of teaching, it could not take this change to the Study Guides (Guias de Estudo). The result is a didactic material that reproduces activities based on a conception of a descriptive and prescriptive teaching. What is concerned about the proposals for the textual production, it is shown that it is given in an artificial way, without any expression and with no link to any communicative context and sometimes, with no relation to the topic it was supposed to be related to

Caracterização e modelagem dos sistemas de produção de caprinos leiteiros

The objectives of this research were characterizing the dairy goat production systems and model it using linear program. On the first step of this research, the model was developed using data from farms that was affiliated in the ACCOMIG/Caprileite, used a similar dairy goat production systems and have a partnership program with Universidade Federal de Minas Gerais . The data of research were from a structured questionnaire applied with farmers and monitoring of production systems during a guided visit on their farms. The results permitted identify that all farms were classified as a small and have a intensive production system. The average herd size had 63.75 dairy goats on lactation; it permits a production of 153, 38 kg of goat milk per day. It was observed that existing more than one channel of commercialization for the goat milk and their derivative products. The data obtained, on the first step of this research, was used to develop a linear program model. It was evaluated in two goat production systems, called P1 and P2. The results showed that the P1 system, with an annual birth and lactation during approximately 300 days was the best alternative for business. These results were compared with a mixed (beef and dairy) goat system in the semiarid region, which indicated merged with both systems. Therefore, to achieve profits and sustainability of the system, in all simulations it was necessary a minimum limit of funding of U.S. $ 10,000.00; this value permit earning of U.S. $ 792.00 per month and pay the investment within 5 years
