O estágio foi o campo empírico e os(as) estagiários(as), orientadora/supervisora, alunos(as) e professoras/tutoras foram os protagonistas da trama, que estabeleceram relações pedagógicas diversas. As relações pedagógicas foram observadas durante o estágio e depois analisadas à luz da teoria e dos documentos legais que normatizam o estágio. Na análise, que articulou a teoria e a prática das relações pedagógicas, utilizou-se dos seguintes conceitos: relação, outro, inclusão/exclusão, estágio curricular supervisionado e relação pedagógica. As relações pedagógicas que foram investigadas demonstraram que o estágio curricular supervisionado é um lugar de muitos Outros e que a inclusão/exclusão pode acontecer com qualquer um dos envolvidos na relação. E, também, mostraram q / The present study, which makes use of a qualitative methodoly, shows the result of a research project about the of inclusion/exclusion processes of others in the pedagogical relationships during the supervised curriculum training period from the Biology Science course. The practicum was the empirical field, and the trainee(s), supervisor, student(s) and professor(s) were the protagonists of the plot who established a variety of pedagogical relationships. The pedagogical relationships were observed during the training period and were then analyzed on the basis the theory about the subject, and the legal documents that standardize the training period. In the analysis, that articulated the theory and the practice of pedagogical relationships, there were used the following concepts: relationship, others, inclusion/exclusion, supervised curriculum training period and pedagogical relationship. The investigated pedagogical relationships demonstrated that the supervised curriculum training period is a place of many o

Denna undersökning syftar till att ta reda på vad avgångsstudenter på det fyraåriga sjökaptensprogrammet har för syn på sin egen ledarstil utifrån sina erfarenheter från sin fartygsförlagda utbildning, sin tidigare arbetslivserfarenhet och utifrån teoretiska kunskaper som de inhämtat från den ledarskapskurs som ligger i programmet. Metoden för denna undersökning är kvalitativ, med semistrukturerade intervjuer och litteraturstudier. I undersökningen intervjuades tio sjökaptensstudenter. En intervjuguide användes, som stöd för intervjuaren, vid intervjuerna. Svaren på intervjuerna analyserades utifrån teorin om tre klassiska ledarskapsstilar; auktoritär, demokratisk och passiv. Resultatet visar att sjökaptensstudenter har, utifrån sin fartygsförlagda utbildning och sin tidigare arbetslivserfarenhet, en syn på sin egen ledarstil som stämmer mest överens med en demokratisk ledarstil och delvis med en auktoritär ledarstil. Utifrån sina inhämtade teoretiska kunskaper från ledarskapskursen anser sjökaptensstudenterna att det är viktigt att situationsanpassa sitt ledarskap och att vara flexibel i sin ledarstil. Resultatet tyder på att denna flexibilitet i ledarstil ligger mellan demokratisk och auktoritär ledarstil. / The purpose of this research is to find out how students, graduating from the Master Mariners programme, look at their own leadership style from their experiences from their cadet training period, their earlier work experience and from their acquired knowledge from the course in leadership which is included in the programme. The method used for this research is qualitative, with semi-structured interviews and literature studies. Ten Master Mariner students were interviewed for this research. An interview guide was used, as support to the interviewer, during the interviews. The answers from the interviews were analyzed theoretically on three classical leadership styles; authoritarian, democratic and passive. As regards to the cadet training period and earlier work experience, the result shows that the Master Mariner students regard their own leadership style as to be one that corresponds mostly with a democratic and partly with an authoritarian leadership style. The students think, from their acquired knowledge from the course in leadership, that it is important to be able to adjust one’s leadership according to the situation and to be flexible in one’s leadership style. The result seems to indicate that the flexibility in one’s leadership style lies between a democratic and an authoritarian leadership style.

Title: Changes in motor performance of competition level adolescent and adult football players during winter training period. Objectives: The objective of this thesis is to confirm the efficacy of winter training on changes of motor performance by measuring and comparing topical condition of the players with the help of initial and final somatic and fitness parameters diagnostics of two football teams (adult men and adolescents) that compete in football competitions at similar amateur level and by comparing the achieved results. Methods: The methods used were measuring, comparison and data analysis. The assessment of motor performance of individual players was based on the series of tests UNIFITTEST 6-60 that was complemented with tests of specific football skills: long distance kick and heavy ball throw. Results: The conclusion is that during the winter training period that took 8 weeks included 16 training sessions and several training matches, the proposed training plan affected positively the motor performance of the tested players. The most substantial advance was recorded in 2 km run and long distance kick tests in which 96% of players significantly improved. The Bílé Podolí players improved their run time by 27 seconds on average and the Vrdy players improved by 21 seconds on average. In the...

Wireless communications systems are used today in a variety of milieux, with a recurring theme: users and applications regularly require higher throughput. Multiple antennas enable higher throughput and/or more robust performance than single-antenna communications, with no increase in power or frequency bandwidth. Systems are required which achieve the full potential of this "space-time" communication channel under the significant challenges of time-varying fading, multiple users, and the choice of appropriate coding schemes. This dissertation is focused on solutions to these problems. For the single-user case, there are many well-known coding techniques available; in the first part of this dissertation, the performance of two of these methods are analyzed. Trained and differential modulation are simple coding techniques for single-user time-varying channels. The performance of these coding methods is characterized for a channel having a constant specular component plus a time-varying diffuse component. A first- order auto-regressive model is used to characterize diffuse channel coefficients that vary from symbol to symbol, and is shown to lead to an effective SNR that decreases with time. A lower bound on the capacity of trained modulation is found for the specular/diffuse channel. This bound is maximized over the training length, training frequency, training signal, and training power. Trained modulation is shown to have higher capacity than differential coding, despite the effective SNR penalty of trained modulation versus differential methods. The second part of the dissertation considers the multi-user, multi-antenna channel, for which capacity-approaching codes were previously unavailable. Precoding with the channel inverse is shown to provide capacity that approaches a constant as the number of users and antennas simultaneously increase. To overcome this limitation, a simple encoding algorithm is introduced that operates close to capacity at sum-rates of tens of bits/channel-use. The algorithm is a variation on channel inversion that regularizes the inverse and uses a "sphere encoder" to perturb the data to reduce the energy of the transmitted signal. Simulation results are presented which support our analysis and algorithm development.

Campus Crato, from the perspective of the students. As we know, the mandatory training period is a complementary stage of the learning process and involves a pedagogical structure, from a suitable curriculum to small actions in the school environment, so that we can turn this activity into a reflexive action to develop a coherent relation between practice and theory. We chose the qualitative approach aiming to achieve a better comprehension and to give meanings to the analyzed phenomena. The instruments used to collect the data were questionnaires with open questions. The target of this research was the former students of the Integrated Technician Course who finished in 2010. These instruments enabled us to identify some discrepancies related to the articulation between school, training, and the job market, which have been compromising the role of the farming technician in his/her area of insertion. It's important to highlight that, in addition to these aspects, we aimed to gather specific laws and decrees which influenced the development of this work in Brazil. We endeavored, also, to approach the training practice in a perspective of approximation between propaedeutic and technical teaching, taken as able to provide the student with education to face the challenges of the world of work. / Esta pesquisa teve como objetivo investigar o papel que o est?gio curricular obrigat?rio (ECO) vem desempenhando na forma??o do T?cnico em Agropecu?ria do Instituto Federal de Educa??o do Cear?, Campus Crato, a partir da perspectiva dos discentes. Como se sabe, o est?gio Curricular Obrigat?rio ? uma etapa de complementaridade do processo de aprendizagem e envolve uma estrutura pedag?gica que vai desde curr?culos adequados at? pequenas a??es no ?mbito do ambiente escolar, a fim de que se possa fazer dessa atividade uma a??o reflexiva com vista a desenvolver de forma coesa a rela??o entre teoria e pr?tica. Para melhor interpreta??o e atribuir significados aos fen?menos analisados, fizemos op??o por uma abordagem qualitativa. Os instrumentos utilizados para coleta de dados foram question?rios com perguntas abertas que tiveram como alvo os alunos egressos do Curso Integrado de T?cnico em Agropecu?ria (CITA), do ano de 2010. Esses instrumentos nos possibilitaram identificar algumas discrep?ncias em rela??o ? articula??o entre escola, est?gio e mundo do trabalho, as quais v?m comprometendo a fun??o do T?cnico em Agropecu?ria na sua ?rea de inser??o. ? importante registrar que al?m desses aspectos, procuramos elencar leis e decretos espec?ficos que influenciaram o desenvolvimento dessa atividade no Brasil. Buscamos, tamb?m, abordar a pr?tica do est?gio numa perspectiva de aproxima??o entre ensino proped?utico e t?cnico, entendidos como capazes de potencializar ao educando uma forma??o para enfrentamento das incertezas do mundo do trabalho.

O tema tem sido estudado e discutido por vários pesquisadores preocupados com as concepções que se transportam de um indivíduo a outro no processo de ensinar e aprender uma Língua Estrangeira, uma vez que criamos nossas concepções na interação com o outro. Assim, crença é toda a ideia que uma pessoa toma por verdadeiro, influenciando suas ações. E a partir de princípios sociointeracionais orientados pelas proposições de Vygotsky (1998), Lantolf (2000) e Mitchell e Myles (2004), e considerações sobre crenças de Barcelos (2004 e 2007), bem como outros resultados de pesquisas nessa área (ALVAREZ, 2007; COELHO, 2006 e SILVA 2006), é que se construiu o aporte teórico que guiou este trabalho. Os dados foram levantados através de um estudo qualitativo, envolvendo questionário, observação e gravação das aulas de quatro alunos-professores, selecionados aleatoriamente, em período de estágio, e ainda foram analisados os planos de aula e relatórios. Finalmente, por meio de uma triangulação de informações foram identificadas as concepções que permaneceram iguais durante esse processo e as que sofreram algum tipo de alteração. Os resultados indicam que mesmo que os alunos entendam ou reconheçam as considerações teóricas aprendidas ao longo do curso, suas ações nem sempre as acompanham. / This study analyses the beliefs that training students have about teaching and learning English language when they start the period of curricular practices, as well as the changes that may occur in this process. The subject has been studied and discussed by many researchers concerned with the concepts that are transferred from one person to another in the process of teaching and learning a foreign language, since we create our ideas in interaction with others. So belief is the whole idea that a person takes to be true, influencing his actions. And based on interactionist principles guided by the propositions of Vygotsky (1998), Lantolf (2000) and Mitchell and Myles (2004), and considerations regarding the beliefs of Barcelos (2004 and 2007) and other results of research in this area (Alvarez, 2007, Coelho, 2006 and Silva 2006), the theoretical framework that guided this work was built. The data were collected through a qualitative study involving questionnaire, observation and recording classes from four students, and also the lesson plans and reports are analyzed. Finally, through triangulation of information were identified concepts that remain the same during this process and those who suffered some type of change. The results indicate that even if students understand or recognize the theoretical considerations learned along the way, their actions do not always follow them.
