Nesta investigação aprofundamos, tanto quanto nos foi possível, os fundamentos pedagógicos conducentes a aprendizagens significativas, atribuindo especial relevância à diferenciação pedagógica alicerçada numa gestão flexível do currículo. Com este objetivo, para além da revisão da literatura e da subsequente sistematização de conhecimento que se imponha, lançámo-nos a um trabalho empírico com recurso a uma metodologia eminentemente qualitativa, numa sala de aula, duma escola do ensino básico da RAM, consubstanciando um estudo de caso com cariz etnográfico. Recolhemos dados diversificados provenientes de múltiplas fontes de informação, através de variadas técnicas de recolha de dados, que nos deram acesso a um conhecimento aprofundado da cultura de uma sala de aula, designadamente no que às metodologias pedagógicas diz respeito, procurando descortinar as estratégias de diferenciação pedagógica desenvolvida pela docente O processo vivenciado e os resultados obtidos permitem-nos assegurar que a docente estava a trilhar um caminho rumo à diferenciação pedagógica e à promoção de aprendizagens significativas para todos os alunos. Contudo, também reconhecemos potencialidades emergentes suscetíveis de serem ampliadas e fragilidades que requerem uma reflexão redobrada no sentido de possibilitar a reconfiguração de uma profissionalidade docente e de uma ação educativa cada vez mais qualificada, que permita fomentar ainda mais a progressão das aprendizagens para cada aluno. Trata-se de procurar respostas na edificação de uma profissão alicerçada na partilha e na colegialidade e de negar um ensino simultâneo que já deu provas da sua ineficácia, assumindo a complexidade do ato educativo, na interação com outros profissionais, com outras experiências e é com base neste pressuposto que desenvolvemos a presente investigação, não escondendo a pretensão de que este estudo venha a ser conhecido por um leque alargado de profissionais que ambicionam construir as respostas educativas mais adequadas aos alunos com quem trabalham.

O trabalho aqui apresentado visa dar a conhecer aos leitores como os alunos aprendem Geometria a nível do 7.º ano de escolaridade (3.º Ciclo do Ensino Básico). O que me motivou à escolha deste tema foi compreender o que sentem os alunos quando se deparam com situações problemáticas que envolvem conhecimentos geométricos e como são capazes de as resolver. Por esta razão predispus-me a realizar uma investigação cujo propósito foi compreender como os alunos aprendem Geometria quando frequentam o 7.º ano de escolaridade. Para poder efetuar o estudo, desenvolver o problema proposto e orientar o trabalho de investigação, considerei três questões fundamentais: 1. Como é que a utilização de materiais manipuláveis contribui para a aprendizagem de conceitos e propriedades geométricas? 2. Como é que o uso de software Geométrico contribui para a construção do pensamento geométrico dos alunos? 3. Como é que a utilização de materiais manipuláveis e de software Geométrico contribuem para o desenvolvimento do raciocínio e da comunicação matemática? O estudo foi desenvolvido, ao longo dos segundo e terceiro períodos, do corrente ano letivo, numa turma de 7.º ano de escolaridade de uma escola básica dos 2.º e 3.º ciclos do Concelho de Câmara de Lobos, Ilha da Madeira. Os dados recolhidos foram resultado da aplicação de atividades que envolvem materiais manipuláveis e o programa de Geometria Dinâmica: GeoGebra. Neste trabalho investigativo, utilizei o método qualitativo onde a recolha de dados foi baseada na observação direta dos alunos em contexto sala de aula (com recurso aos meios audiovisuais) e na entrega de resoluções das atividades propostas (em formato de papel e formato digital). A análise dos dados foi realizada de acordo com as questões previamente formuladas. As conclusões refletem o papel essencial do professor como principal mediador de todo o processo de ensino e aprendizagem do aluno, assim como, a importância da diversificação de estratégias na sala de aula de Matemática.

A cutia (Dasyprocta aguti) é um roedor silvestre encontrado amplamente na região Nordeste do Brasil. É uma espécie muito utilizada pela população humana de baixa renda como fonte alternativa de proteína na alimentação. Foram utilizadas 31 cutias, machos, provenientes da Universidade Federal do Piauí (FUFPI), Estado do Piauí e da Escola Superior de Agricultura de Mossoró Estado do Rio Grande do Norte. Os animais foram divididos em grupos etários desde o nascimento até os 14 meses de idade. O diâmetro nuclear médio foi obtido pela medida de 10 núcleos do tipo celular estudado em cada testículo, no estágio 1 do ciclo do epitélio seminífero. Nos animais que não apresentaram o epitélio organizado em estágios bem definidos em virtude da idade, foram feitas medidas em secções transversais escolhidas somente pelo contorno circular. O início da assincronia do processo espermatogênico foi observado a partir dos seis meses de idade. A puberdade, na cutia Dasyprocta aguti, foi definitivamente estabelecida a partir dos nove meses de idade, pois estavam presentes todos os tipos celulares e espermatozóides liberados no lume tubular em grande parte do parênquima testicular.

The dialogue between philosopher Ludwig Wittgenstein s notions and Pierre Bourdieu s sociological concepts related to social practice of language shows that the philosophy of language has an important influence on contemporary social theory. When we compare the ideas of these authors we discover that beyond the direct influences from the philosopher that the sociologist recognizes there are great parallelisms of thought. That is, Wittgenstein s pragmatic thought of the use of language does not concern only language, but also every socially built behavior. When we notice that the social and linguistic behavior are borne by the individual in a tacit way, that leads us to theorize about the prereflective dimension that builds human actions and even the habits of thought. The same processes allow the uses of language to build wider social practices. Besides, John Austin, one of Wittgenstein s disciples, and his speech acts theory, contribute with a way to reflecting on how language ressembles a concrete action. Finally, the linguistc therapy that Wittgenstein means to be his philosophical proposal is assimilated by Bourdieu, who takes it as one of the necessary topics of the sociological work

This study investigated how the process of the constitution of the subject is interpreted in the formulations of the founders of socio-historical psychology (Lev S. Vigotski, Alexei N. Leontiev and Alexander R. Luria) and in the sociology of knowledge of Peter Berger and Thomas Luckmann. These two theoretical perspectives, despite having different philosophical formulations as ontological and epistemological intentions (socio-historical psychology, historical dialectical materialism; the sociology of Berger and Luckmann and phenomenology) arrive, however, at the same basic conclusion about the social nature of the subject. The objective of the study, therefore, was that of identifying the differences and convergences between the two perspectives and then, try to determine the possibility of a theoretical synthesis between them in relation to the constitution of the subject. At the same time, we intended to analyse the implications of this possible synthesis in order to comprehend the manner in which the ideology functions in human societies as thought by Louis Althusser and Alípio de Sousa Filho. We arrived at the conclusion that, despite being incompatible from the ontological and epistemological points of view, a synthesis is possible between socio-historical psychology and the sociology of knowledge of Berger and Luckmann in relation to the conception of society and the comprehension of the process of the constitution of the subject. Starting from the philosophical intentions of socio-historical psychology, it is possible to incorporate, enriching points such as: Berger s and Luckmann sconception of society and the interpretation of the process of constitution of the subject. This possible synthesis, when interpreted in light of the reflections of Althusser and Sousa Filho on the phenomenon of ideology in human societies, is constituted in a real unveiling of the concrete provisos by which the ideology acts in human societies in order to transform biological examples of the human species in specific social subjects

O desempenho germinativo de sementes de Dalbergia nigra (jacarandá-da-bahia) foi avaliado em laboratório e viveiro, com o objetivo de verificar a eficiência do teste de germinação em laboratório em predizer o comportamento de lotes de sementes em condições de viveiro. Para tanto sementes pertencentes a três lotes (anos de colheita: lote I - 1998, lote II - 1997 e lote III - 1994) foram utilizados para determinar os dados biométricos, teor de água, germinação, índice de velocidade e primeira contagem da germinação e porcentagem de plântulas normais em laboratório e emergência, índice de velocidade de emergência e porcentagem de plântulas normais em viveiro. Sementes pertencentes ao lote III apresentaram qualidade inferior aos lotes I e II, tanto em laboratório como em viveiro. Os altos valores do coeficiente de correlação simples entre as características avaliadas nas duas condições, evidenciam a eficiência do teste de germinação em laboratório em predizer o desempenho germinativo de sementes de jacarandá-da-bahia em viveiro.

This work aims to present a systematic study of sociology developed by Josué de Castro. It is a theoretical work that aims to evidence the potentialities and limitations of the hunger analysis theoretical models of contemporary sociology. It was used concepts of Social Institution (Berguer and Bourdieu), Habitus-precário and Ralé (Jessé Sousa) as weapons to comprehend better the hunger phenomenon on the sociology field, to consequently generate dialogs between Castros writings and the contemporary sociology. It demonstrates how hunger reproduces more by pre reflexive behavior patterns in a way that the moral rules become invisible and allow the phenomenon to continue in an invisible way

As Sociology becomes a mandatory subject in the curricular componentof Brazilian high schools, we find anopportune moment to proposals and changes in the subject and in teaching, in a general aspect. It s noticed the great importance of the role that the create imagination plays in individual s formation (BACHELARD), and it s also seen that Brazilian education system has marginalized imagination to the detriment of a unifocused scientism that sterilizes creativity, playfulness and poetry in its educational process. Nevertheless, a way of thinking redefinitions to the educational horizons of Sociology as a subject and education is upheld. An educational practice that reconnects the prosaic and the poetic, using images/songs as paths/strategies of the teaching-learning process. As for that, the school structure was used where the tutor work was done to undertake experiences that made the use of songs as strategy to facilitate/stimulate the learning of the subject Sociology in high school. From thoughts and results of this experience, plus the bibliographic studies, analysis were made. The goal of this essay is to make use and stimulate the creation of poetic images from the teaching point of view, specially the Sociology subject in high school, rethinking and searching more efficient and playful ways of approaching and building educational methods from images; stimulating the development of the Thinking Reform and the Anthropoetics of the human gender (MORIN); acknowledging that imagination is an indispensable part of our integral formation

In this master s thesis I intend to carry out an interpretation of Michel Foucault s thought that points out the relations and theoretical, conceptual and thematic consequences with sociology in his work and theoretical propositions. For my argumentation and analysis I take as a base a specific part of his thought: the problem of domination in modern societies in the genealogic texts in the decade of 1970. It s about to identify how Foucault does his analysis of the relations of domination and the use of the power with the objective to suggest and point out his contribution to sociological analysis of domination. I will discuss the foucaultian program of the study of domination from four units of analysis: person constitution, knowledge, power and truth. The structure and division of the chapters will follow the specific and detailed study of each of those units of analysis, prioritizing their theoretical sense and consequences to the sociology. Thus, in the first chapter, I will highlight a little more the relations of affinity and the convergences between Foucault and the sociology in a way to offer more elements to justify the general objectives that this work intends to achieve. In the second chapter, I will analyze the subject of domination in Foucault s thought, discussing his basic presuppositions and its intrinsic relation with the heart of the foucaultian philosophical project, the person constitution. In turn, in the third and fourth chapter, I will discuss the interdependence between knowledge and power as an essential and opaque dimension of the ways of modern domination. In the fifth chapter, I will analyze the relation between domination and the truth discourse production

It discusses the Health Care of the Elderly in the town of Mossoró, traversing the paths that discussed the history of health care, which has been altered by the new (con) formation and required adjustments of society which led the development and implementation of the National Health Care for the Elderly with the backdrop of the guiding principles of the Health System - SUS. The goals outlined were: To map the implementation of the policy of health care for the elderly in Mossoró considering whether this is based on the principles and guidelines of the NHS and National Health Policy of the Elderly; Check if health promotion is seen as a strategy that favors the elderly mossoroenses the possibility of healthy aging; identify the discourse of the elderly about the aging process and the strategies you use to take care of your needs. Applies as a methodological strategy BOAS, complemented by interviews with twenty (20) elderly residents of Mossoró with a view to understand the objective elements, and the political and subjective traits that express a regularity which marks the area of health care mossoroense elderly. The data were tabulated and the BOAS divided into nine sections for analysis. The speeches were transcribed seized and subjected to a thorough reading that allowed the visualization of issues that have been examined with theoretical and methodological support to the model proposed by Boaventura de Souza Santos (2006) designated this cosmopolitan reason being supported by three meta-sociological procedures, namely, the sociology of absences, the sociology of translation work and emergencies. It appears as a result the exclusion and discrimination of the elderly in different social settings, a condition that prevents them from being aware of their importance as citizens deserving of decent treatment and respect for the family, society and the government, when addressing health the elderly said the need to propose alternative models of care that has the paradigm of health promotion. We conclude that in these areas, meetings are held, to draw lines that were heterogeneous because they were built by the dissimilarities that engender incessantly and show that although we have advanced regarding the attention of the elderly in Mossoró there is still a long way to go in order to meet the needs revealed by the elderly. It is suggested that the practice of trial-creation-differentiation, while highlighting the historical and procedural dimension, deconstructions and negotiations with collective effects. A democratic paradigm and analytical creeps: the constitution are moments of Health Care for the Elderly shaping a new landscape in the town of Mossoró.

Background: Embryonic stem cells are cells derived from early-stage embryos that are characterized by pluripotency and self-renewal capacity. The in vitro cultured murine embryonic stem cells can indefinitely propagate in an undifferentiated state in the presence of leukemia inhibitory factor (LIF). However, when stimulated, these cells can differentiate into cell lines derived from all three embryonic germ layers. The trichostatin A (TSA) is an epigenetic modifier agent and several studies have used the TSA to stimulate cellular differentiation. However, most of these studies only assessed one TSA concentration. Therefore, this study aimed to evaluate the effects of different TSA concentrations on histone hyperacetylation during in vitro cell differentiation of murine pluripotent embryonic stem cells, cultured with or without LIF, in the quest of to standardize their application on early cultures of embryonic stem cells.Materials, Methods & Results: Undifferentiated murine embryonic stem cells were plated in the presence of different TSA concentrations (0 nM, 15 nm, 50 nM and 100 nM) in the presence or absence of LIF. Thus, the treatments were evaluated in undifferentiated embryonic stem cells cultured in the presence of LIF (Control group: 0 nM LIF(+); Group 15 nM LIF+; Group 50 nM LIF+ and Group 100 nM LIF+), and in embryonic stem cells cultured in the absence of LIF (Control group: 0 nM LIF; Group 15 nM LIF(-); Group 50 nM LIF(-) and Group 100 nM LIF-). Treatment with TSA was performed for 24 h. After that the medium was replaced with fresh medium without TSA. Samples were collected at 0, 12, 24, 36 and 48 h after the beginning of the experiment. Three replicates were performed in each experimental group. The relative amount of Histone H3 lysine 9 acetylation was analyzed in all groups, as well as the cell proliferation in the embryonic stem cells cultured in the presence of LIF. In the control group (0 nM), the absence of LIF resulted in higher levels (P < 0.05) of H3lys9ac compared to the cultures supplemented with LIF. In the embryonic stem cells cultured in the presence of LIF, the 50 nM and 100 nM treatments resulted in higher levels (P < 0.05) of H3lys9ac when compared with 0 nM and 15 nM treatments. Evaluating the Hoechst area in the 0 nM group, it was observed that the number of cells increased (P < 0.05) according to the time of culture. Treatment with 15 nM also reflected a similar distribution, but the Hoechst area in 15 nM group was lower (P < 0.05) at 24 and 48h when compared to the observed in the control group. In the 100 nM treatment, was observed that the area of Hoechst was lower (P < 0.05) to that obtained in the control group at 12, 24 and 48h. In addition, it was observed that treatment with TSA induces greater cellular differentiation when compared to control groups in stem cells cultured in the presence of LIF as well as in the absence of LIF.Discussion: In the present study it was observed that TSA treatment increased the levels of histone acetylation in murine embryonic stem cells at a 50 nM concentration, making it possible to reduce the concentration recommended in the literature (100 nM). In addtion, it was concluded that the lower TSA concentrations utilized (15 nm and 50 nM) was less harmful to cellular proliferation than the 100 nM TSA concentration.
