Estilo de liderança e papel de coordenador do CAP na motivação da sua equipa

A presente investigação empírica pretendeu averiguar o estilo de liderança e o papel do Coordenador, do Centro de Apoio Psicopedagógico do Funchal – 2.º, 3.º Ciclos e Secundário, na motivação da sua equipa. Deste modo, as temáticas liderança e motivação constituíram o quadro teórico desta dissertação. Como estratégia metodológica optámos pelo estudo de caso, com recurso às técnicas de inquérito por questionário e entrevista. O questionário aplicado foi o Multifactor Leadership Questionnaire (MLQ), da autoria de Bernard Bass e Bruce Avolio, para verificarmos o estilo de liderança do Coordenador, percepcionado pelos trinta e sete elementos da equipa. Por sua vez, a entrevista, do tipo semi-estruturada, foi efectuada ao Coordenador, com o intuito de investigarmos a percepção do cargo por si desempenhado, mais especificamente, o modo como influencia a motivação da equipa. Os resultados da investigação sugerem que o Coordenador exibe uma presença partilhada dos estilos de Liderança Transaccional e Transformacional. Quanto ao seu papel na motivação da equipa, os resultados apontam para a influência através da inspiração motivacional e do desenvolvimento de um sentido de missão colectivo para que a “filosofia da inclusão seja uma realidade”. Através do significado que atribuiu ao trabalho que realiza e à satisfação pela convergência entre os ideais pessoais e organizacionais, concluímos que o Coordenador se encontra motivado para o desempenho do cargo de coordenação. No entanto, no que diz respeito à sua equipa, considerou-a pouco motivada, devido a contingências situacionais. A falta de motivação impõe-se como uma dificuldade complexa, para a qual não existem estratégias motivacionais universais. Assim, é fundamental que o Coordenador, além de estar motivado, deve ser motivador, assumindo um papel de extrema importância e uma função estratégica, de modo que os objectivos organizacionais sejam atingidos.

A liderança e suas relações com o comprometimento organizacional

This study presents the results of field research of an exploratory descriptive character that seeks to identify the latent dimensions of leadership and organizational commitment as well as to discover the relationship between these two sets of indicators. In the study, 236 respondents were interviewed, 84 being managers or owners and 152 being sales personnel. The research was undertaken in five shopping centers in the municipality of Natal, capital of Rio Grande do Norte, and employed two different questionnaires. One of them was developed by Bass and Avolio, 1992 (in NORTHOUSE, 2004), contained 21 indicators of leadership and was completed by store managers. The other instrument, completed by sales personnel in the stores, was developed by Medeiros, Albuquerque, Marques and Siqueira (2003) and contained a total of 28 indicators of organizational commitment. For the analysis of the data, factor analysis techniques and structural equations modeling were used. Using the factor analysis, five dimensions of leadership and seven dimensions of organizational commitment were found, all of which have a theoretical basis for their explanation. Through the structural equations modeling, a relationship was established between leadership and organizational commitment, in which it was possible to observe that certain leadership styles influence in a positive form the commitment of the employee

Aspectos biológicos do peixe-olhudo-dentinho, Synagrops bellus (Actinopterygii: Acropomatidae), da plataforma externa e talude superior do estado de São Paulo, Brasil.

Biological aspects of the blackmouth bass Synagrops bellus from the outer shelf and upper slope along the coast of São Paulo, southeastern Brazil, are presented. The species represented about 71.6% and 9.7% in number of the total catch performed by balloom trawl in the isobaths of 300m and 500m respectively. Body sizes of 266 individuals ranged between 130 and 265mm total length, with sex ratio of 55.9% males, and 44.1% females, where most individuals were in maturation stage. Twenty two food items were found, pointing out Myctophidae fishes, Penaeidea and Caridea shrimps, Brachyuran megalopae, Enoploteuthidae and Cranchiidae cephalopods, pteropods and tunicates. The intestinal coefficient increases as the body size increase, and the number of gill rakers ranged between 16 and 17. Length-weight relationship was WT = 6.0 x 10-6 x TL3.12, r2 = 0.9495. Synagrops bellus is an important link between zooplankton and micronekton, and demersal and pelagic predators in the outer shelf and upper slope in southwestern Brazilian coast.

Characterization of the genetic variability among Caesalpinia pulcherrima (L.) Sw. (Fabaceae) plants using RAPD molecular markers

O flamboyanzinho (Caesalpinia pulcherrima, Fabaceae) é muito utilizado como cerca-viva e na arborização de ruas, parques e jardins. de florescimento exuberante, suas flores podem apresentar coloração rosa, laranja ou amarela, conforme a variedade. Como características florais são essenciais para a definição do valor comercial de espécies ornamentais, o objetivo principal do trabalho foi verificar a existência de polimorfismo entre plantas de C. pulcherrima, que produzem flores de diferentes colorações, por marcadores moleculares RAPD. Foram escolhidas aleatoriamente 30 plantas adultas, cultivadas no município de Jaboticabal, Estado de São Paulo, para a retirada de amostras foliares para a extração de DNA. Dentre essas matrizes, 20 possuem flores alaranjadas, oito, flores amarelas, e apenas duas produzem flores de coloração rosa. Dos 140 primers de RAPD avaliados, 94 foram capazes de ampliar fragmentos definidos, gerando 246 bandas, das quais se observou 100% de bandas monomórficas, indicando que nenhum dos primers utilizados detectou polimorfismo entre os tratamentos. Concluiu-se que a técnica para detecção de polimorfismo por marcadores RAPD não foi eficiente, e que existe a necessidade de se testarem marcadores moleculares mais específicos. Além disso, a característica morfológica cor de flor é, possivelmente, controlada por vários genes ou pela combinação deles.

Foucault : a experiência da amizade

Exaltée par la philosophie et reléguée à second plan par la sociologie, pour son appartenance à la vie privée, l amitié devient, à partir des anées 70, um thème d intétêret nom plus sous la perspective classique de la philia, avec son insistance sur la fraternité, égalité et dans l équivalence des amis.Les études de Hannah Arendt,Blanchot,Derrida et Foucault déséquilibrent cette vison, et la rédéfinissent em tant qu ne rapport qui donne lieu à l alterité et permet les manifestations des singularités entre amis. En reprendant ces penseurs, Michel Foucault tente réhabililiter l amitié en tant qu ne éthique et une esthétique de l existence qui conduit à la transformation du sujet, stylisant son existence dans la présence de l autre. Basés sur cette réhabilitation, nous penserons l amitié comme une expérience éthique et afective intense qui cherche autotransformation des amis, une forme de vie qui refuse les formes imposées de rapports et subjectivités

Beleza e poder na Ginástica Rítmica: reflexões para a educação física

La beauté dans la Gymnastique Rythmique (GR) s est esquissée comme condition de son existence. Pour son analyse, nous avons eu recourt au discours sur le pouvoir de Foucault (1971, 1979, 1987, 1988, 1997, 2003) et à sa relation avec la production de savoirs. Basés sur cette compréhension, nous avons réfléchi sur les relations de pouvoir dans la GR qui se sont établies et consolidées grâce à la réglementation de sa pratique, dans lequel le Code de Pointage a un rôle prépondérant. Ainsi, la GR a construit sa beauté à travers les temps au moyen de jeux de force où la gestualité de corps performatiques, à travers la discipline, a été prépondérant. Cette dernière a configuré des sens attelés à la coercition-résistence des corps: la production de discours. C est en pensant à une beauté comme ume trame de discours construits par ces relations de pouvoir-savoir des investissements du corps dans la Gymanstique Rythmique que nous nous posons les questions: Comment le Code de Pointage réglemente la gymanstique rythmique et sportive au sujet de la construction de la beauté ? Quelle est la relation entre les pouvoirs et les savoirs impliqués dans cette réglementation ? Nous avons donc pour objectifs de rechercher la beauté dans la Gymnastique Rythmique comme savoir produit à partir des relations du pouvoir circonscrites dans les règles de la modalité et de discuter la beauté à partir de la relation pouvoir/savoir comme réflexion pour le milieu de l éducation physique. Nous avons utilisé comme méthodologie la technique de l analyse de contenu (Bardin, 1977) afin d analyser le Code de Pointage de la GR dans sa version 2005-2008. Nous avons également fait usage des images de gymnastes comme moyen analogique pour amplifier le sens des discussions. La lecture fluctuante nous a permis de sélectionner des unités significatives et d organiser nos discussions en trois axes thématiques qui composent le premier chapitre intitulé « La beauté réglementée ». Dans ce chapitre, nous discutons les spécificités de la GR, la prescription de l utilisation du temps et de l espace et la configuration du geste technique à partir de l analyse de son code de ponctuation. Dans le deuxième chapitre, « Le corps beau transcende la règle », nous réalisons quelques réflexions destinées à l éducation physique à partir de la discussion du chapitre antérieur en prenant pour cible trois sujets : Pouvoirs et Savoirs, Technique et Style, Beauté et Éducation. Nous avons ainsi constaté que la beauté de la Gymnastique Rythmique contemporaine est entourée par sa réglementation, mais a été et continue à être dessinée par des mécanismes de pouvoir-savoir tout au long de sa trajectoire historique. Malgré l existence de conditions pour la beauté dans le Code de Pointage de la GR, il existe la possibilité de la création du propre style par la gymnaste, par la possibilité de vivre l improvisé et l imprévu, de sensibiliser le public, parce que le pouvoir crée des savoirs et le corps, qui se dépasse, créera toujours de nouvelles formes d être beau. La constatation que le Code de Pointage produit une beauté et que la gymnaste la reconstruit continuellement en en réactualisant les règles est une réflexion importante pour l éducation physique: elle réaffirme que le corps n est jamais seulement soumis, que même dans la soumission il est capable de produir du savoir, d être beau et de créer de nouveaux sens pour la Culture de Mouvements

O grupo escolar modelo augusto severo (1908-1928): vinte anos de formação de professores

Ce travail a pour objet d'étude le Groupe Scolaire Augusto Severo, situé à Natal, première institution du type dans l'État du Rio Grande do Norte. Il analyse la pratique pédagogique, le modèle d'éducation primaire et d'expérimentation des personnes en formation de l'École Normale de Natal, entre 1908 et l'année de 1928. Dans cette période, se sont produites des tentatives d'organisation scolaire par le biais de la Réforme de l‟Enseignement Primaire (1908) et de la Réforme de l‟Enseignement (1916). Nous nous sommes basés sur l'Histoire Culturelle définie à travers la conjonction de l'histoire des objets dans sa matérialité, des pratiques dans leurs différences et configurations, des dispositifs dans leurs variations. Nous avons utilisé les journaux A República et Diário do Natal, la revue Pedagogium, des Lois, des Décrets et Messages du Gouvernement, des Codes d'Enseignement et le Régime Interne des Groupes Scolaires, documents qui proviennent du fonds de l'Institut Historique et Géographique do Rio Grande do Norte (IHGRN) et des sources iconographiques, provenant de l'Institut du Patrimoine Historique et Artistique National (IPHAN/RN). Dans les Archives Publiques de l‟Etat (APE/RN) nous avons recherché les Livres d'Enregistrement des Groupes Scolaires et Écoles Isolées, Offices, Inscriptions, Rapports et Actes de réunions de la Direction Générale de l'Instruction Publique et Journal de Classe. Nous avons analysé l'action des professeurs dans cette institution primaire, ainsi que l'histoire des disciplines scolaires et des programmes d'enseignement, la problématique des contenus et méthodes. Nous avons observé que la méthode intuitive était la dynamique de la pratique pédagogique efficace et que les rites de récompense, les cérémonies civiques composaient l‟ensemble des idées modernisatrices de l‟époque

Desinfecção solar de água para comunidades de baixa renda

The use of solar energy for water disinfection, and is accessible to disadvantaged communities because of its low cost, has the advantage of using disposable materials such as bottles of polyethylene terephthalate (PET). We present a study that used two methods of disinfection: the methodology proposed by the project Solar Water Disinfection (SODIS), which consisted of water disinfection by solar radiation and temperature and the methodology which the temperature of the water for disinfection. In both, we seek to eliminate microorganisms that cause serious diseases such as dysentery, typhoid, cholera, etc. Water samples were collected in the community of Bass, where the population has low income and the incidence of waterborne diseases is high. The experiments were divided into two stages. In step 1 we studied the feasibility of disinfection and in step 2 the feasibility of the pilot plant to obtain adequate levels of disinfection temperatures desired. The results showed the efficiency of the disinfection process, reaching an average of 80 to 100% death of microorganisms, but regrowth was observed in some samples. Finally on the good results of stage 1, is designed and built and tested in an experimental pilot plant, which has shown to be feasible to promote water disinfection through the use of solar energy. The water after treatment is in accordance with the limits established by Brazilian legislation for clean water, maintaining a positive performance for the disinfection and acceptable levels of bacterial regrowth

As relações entre tectonismo e seqüências deposiconais no rifte potiguar - porção SW do Graben de Umbuzeiro, bacia potiguar emersa

Through an integrated approach, using litho, chrono and biostratigraphic data, the relative importance of climate variations and tectonics were recognized in rift sediments of the onshore Potiguar Basin, Northeast Brazil. Concepts of sequence stratigraphy were applied as a template to integrate sedimentological and geochemical data (oxygen isotopes), as well as quantitative palynologic methods to address and recognize the main depositional patterns produced in a rift basin. The main objective was to address the relative importance of climate changes and tectonics to the resultant stratigraphic architecture. The results of computer simulations of sedimentary basin fills of rift basins were quite useful to test working hypothesis and mimic the process of filling a half graben during a rift event. The studied section includes a neovalanginian-eobarremian (Lower Cretaceous) rift interval from the Pendência Formation, located in the southwestern portion of Umbuzeiro Graben, in the offshore Potiguar Basin. The depositional setting is interpreted as progradational deltaic system entering a lake from its flexural margin. Sismoestratigraphyc and well logs analyses allowed to interpret two regressive intervals (Green and Yellow Sequences), separated by a broad transgressive interval (Orange Sequence), known as the Livramento Shale. The depositional history encompass three stages: two tectonically active phases, during the deposition of the Green and Yellow Sequences, and a tectonically quiescent phase, during the deposition of the Orange Sequence. Paleoclimatic interpretation, based on quantitative palynology and geochemical data (��18O), suggests a tendency to arid conditions during the tectonically active phases and wet conditions during the tectonically quiescent phase. Stratigraphic modeling and backstripping techniques, supported by paleoclimatic/paleoecologic interpretations provide a powerful methodology to evaluate the tectonic and climatic controls on tectonic lakes

Running couplings for the simultaneous decoupling of heavy quarks

Scale-invariant running couplings are constructed for several quarks being decoupled together, without reference to intermediate thresholds. Large-momentum scales can also be included. The result is a multi-scale generalization of the renormalization group applicable to any order. Inconsistencies in the usual decoupling procedure with a single running coupling can then be avoided, e.g., when cancelling anomalous corrections from t, b quarks to the axial charge of the proton.

Variabilidade espacial e controle estatístico do processo de perdas na colheita mecanizada do algodoeiro

Dentro do processo produtivo, a colheita, se mal conduzida, poderá causar prejuízos quali-quantitativos no produto final. Dessa forma, esse trabalho teve o objetivo de avaliar as perdas quantitativas, no solo e na planta, na colheita mecanizada de algodão, no ano agrícola de 2006, em Ipameri-GO, em um talhão de 1,4 ha, sendo georreferenciados 41 pontos, distanciados de 50 m no sentido da curva de nível e 9 m entre fileiras. As amostras foram coletadas colocando-se uma armação de 4,5 m² sobre o solo, coletando todo o algodão caído no solo e, em seguida, fez-se a coleta do algodão que permaneceu na planta após a passagem da colhedora. Além das perdas quantitativas determinaram-se o teor médio de água do algodão e o Rendimento Potencial Máximo (RPM). Foram construídas cartas de controle para verificar a qualidade da operação de colheita. Observou-se que as perdas na colheita do algodão foram altas, principalmente as perdas no solo (PS), indicando que a colhedora não apresentou boa eficiência de colheita. As perdas no solo não apresentaram dependência espacial, enquanto as perdas na planta e totais apresentaram dependência moderada e forte, respectivamente. O processo de colheita de algodão não se encontra dentro dos padrões de qualidade, sob o ponto de vista de controle estatístico de processo, devendo ser revistas as condições de colheita.

Chemosystematic studies of natural compounds isolated from Asteraceae: characterization of tribes by principal component analysis

This work describes an application of principal component analysis (PCA) on a database of secondary metabolites from the Asteraceae family. The numbers of occurrences of metabolites in 11 chemical classes for the different vibes of the family were used as variables, PCA allows the identification of chemical classes that contribute most to the subgroups classification within the family. Relationships between chemical composition and botanical classification were made. (C) 2001 Elsevier B.V. B.V. All rights reserved.

Chemical evolution in the Asteraceae. The Oxidation-Reduction mechanism and production of secondary metabolites

This work describes the application of partial least squares (PLS) regression to variables that represent the oxidation data of several types of secondary metabolite isolated from the family Asteraceae. The oxidation states were calculated for each carbon atom of the involved compounds after these had been matched with their biogenetic precursor. The states of oxidation variations were named oxidation steps. This methodology represents a new approach to inspect the oxidative changes in taxa. Partial least square (PLS) regression was used to inspect the relationships among terpenoids, cournarins, polyacetylenes, and flavonoids from a data base containing approximately 27,000 botanical entries. The results show an interdependence between the average oxidation states of each class of secondary metabolite at tribe and sub tribe levels.
