Michel Foucault e a dominação: contribuições para a sociologia

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

Corpo e escrita: linhas e entrelinhas da produção de conhecimento em sala de aula

Body and writing: Lines and between-lines of production of knowledge in the classroom it is an ethnographic research, longitudinal character, based on experience while experienced educator of the Escola Municipal Professor Amadeu Araújo, located in the city of Natal-RN, from which are made reflections about texts written by students who have distorted age/education level, in the process of literacy. Here as initial goal: to discuss the production of students writing as a process body, considering the record of experiences and the impressions they have made during the teaching process. We initially by a conception of phenomenological body, by understanding it in its complexity, a phenomenon that is made from its relationship with the world and with the Other. The records examined were produced between the year 2000 and 2005 involving writings of 106 students, constituting a universe of 136 texts, from which, delimited a corpus of 27 texts. The relevance with respect to the theme and recurrence in which they were detected, were up to elements that allowed a systematization methodology, defining the following units of analysis: Body, written in everyday; body, written and sexuality; body, written and enjoyment poetics; body, writing and other stories. We used the techniques of search, participant observation, based on the actions and interactions body expressed during the experiment and the analysis of documents that consisted of students in the texts and secondary sources, among them, the records of daily class, reports and projects developed, as well as reports of my pedagogical practice, as a researcher inserted in the investigative process. The experience developed, showed a writing school able to express nuances of human complexity, showing that learning is made in the action body, crossed by various forms of language and pointing to the relevance of a pedagogical work able to articulate the dialogue between the written and registrations body of the students, as subjects of learning

O ecoturismo sob a égide da sociedade do consumo: um estudo das Unidades de Conservação de uso sustentável do RN

Ecotourism, in face to environmental demands and discussions, has achieved prominence in the tourism market and wide global development, occasioning a concern about the need for a scientific deepening through a critical approach of the dynamics of consumption and conservation that permeate this practice. This study addresses the ecotourism under aegis of consumer society, in which is perceived that it constitutes a contester practice of society in which it is embedded, nevertheless has been subjected to the logic of capital through commodification of nature. In order to comprehend the reality presented, this study had as geographical cutting two Conservation Units of Sustainable Use in Rio Grande do Norte state: the Jenipabu Environmental Protection Area (APAJ) and Ponta do Tubarão State Sustainable Development Reserve (RDSEPT). The research sought to investigate the relationship between conservation and consumption and their influences on ecotourism held in the Conservation Units (UCs) of sustainable use selected for this study. To this aim it was made a critical reflection about the relationship conservation versus consumption constant in the practice of ecotourism in UCs in the context of current society, analyzing the historical process of formation of UCs of sustainable use in RN state under the light of the contradictory pair conservation-consumption, as well as looking to apprehend the perception of ecotourism of the actors involved with this practice. It was adopted a qualitative approach under a critical perspective based on bibliographical and documentary research and realization of semi-structured interviews with three groups of actors, namely managers/technician, community and ectourists involved with ecotourism in the selected UCs. The analysis was made using two basic units of analysis (consumption and maintenance) and twelve categories. For definition of units of analysis and categories were taken as reference the authors Santos (1987; 1988; 1994; 2001; 2006), Guerreiro Ramos (1989) and A. B. Rodrigues (1996; 2003), which perform critical to society of consumption and describe the key characteristics of the technical-scientific-informational predominant means, and Diegues (1998; 2000), A. B. Rodrigues (2001), Pires (2002) and Neiman and Rabinovici (2010), which discusse historic and scientifically about the emphasis on conservation present in origins and discourse of ecotourism, describing also its founding characteristics. The main results show that the marketing use of the prefix eco has acted as a new dress for what in reality is in fact ancient, ie, the conservation is used as a justification for another new type of consumption. The results also show that despite the coexistence of commercial and symbolic intentions in both UCs, one can observe the predominance consumer society characteristics in the process of creation and the production activities of APAJ, while in RDSEPT we note the predominance of the conservationist characteristics proclaimed by ecotourism. It can be inferred therefore that tourism held in the APAJ can not be called ecotourism, while the practice found in RDSEPT show an alignment with the guidelines of ecotourism

A desigualdade espacial do Baixo Peso ao Nascer no Brasil

Low birth weight (LBW) is a risk factor for neonatal and infant morbidity and mortality. In Brazil the highest percentages of low birth weight occur in regions of higher socio-economic status. The scope of this article is to ascertain the spatial distribution of low birth weight rates and the correlation with social and service indicators. The scale is ecological taking all the Brazilian states as units of analysis. The spatial analysis technique is the methodology used together with data from SINASC, IPEA and IBGE for 2009. Higher rates of low birth weight are found in the south/southeastern states (Global Moran: 0.267, p = 0.02). Clusters of the high-high type in the Southeast and of the low-low variety in states in the Amazon region are detected. The spatial inequality of low birth weight reflects the socio-economic conditions of the states. More developed regions have higher rates of low birth weight, therefore, the presence of the service and its use decrease infant mortality and increase LBW.

The influence of interhemispheric connections on ongoing and evoked orientation preference maps and spiking activity in the cat primary visual cortex

In the primary visual cortex, neurons with similar physiological features are clustered together in columns extending through all six cortical layers. These columns form modular orientation preference maps. Long-range lateral fibers are associated to the structure of orientation maps since they do not connect columns randomly; they rather cluster in regular intervals and interconnect predominantly columns of neurons responding to similar stimulus features. Single orientation preference maps – the joint activation of domains preferring the same orientation - were observed to emerge spontaneously and it was speculated whether this structured ongoing activation could be caused by the underlying patchy lateral connectivity. Since long-range lateral connections share many features, i.e. clustering, orientation selectivity, with visual inter-hemispheric connections (VIC) through the corpus callosum we used the latter as a model for long-range lateral connectivity. In order to address the question of how the lateral connectivity contributes to spontaneously generated maps of one hemisphere we investigated how these maps react to the deactivation of VICs originating from the contralateral hemisphere. To this end, we performed experiments in eight adult cats. We recorded voltage-sensitive dye (VSD) imaging and electrophysiological spiking activity in one brain hemisphere while reversible deactivating the other hemisphere with a cooling technique. In order to compare ongoing activity with evoked activity patterns we first presented oriented gratings as visual stimuli. Gratings had 8 different orientations distributed equally between 0º and 180º. VSD imaged frames obtained during ongoing activity conditions were then compared to the averaged evoked single orientation maps in three different states: baseline, cooling and recovery. Kohonen self-organizing maps were also used as a means of analysis without prior assumption (like the averaged single condition maps) on ongoing activity. We also evaluated if cooling had a differential effect on evoked and ongoing spiking activity of single units. We found that deactivating VICs caused no spatial disruption on the structure of either evoked or ongoing activity maps. The frequency with which a cardinally preferring (0º or 90º) map would emerge, however, decreased significantly for ongoing but not for evoked activity. The same result was found by training self-organizing maps with recorded data as input. Spiking activity of cardinally preferring units also decreased significantly for ongoing when compared to evoked activity. Based on our results we came to the following conclusions: 1) VICs are not a determinant factor of ongoing map structure. Maps continued to be spontaneously generated with the same quality, probably by a combination of ongoing activity from local recurrent connections, thalamocortical loop and feedback connections. 2) VICs account for a cardinal bias in the temporal sequence of ongoing activity patterns, i.e. deactivating VIC decreases the probability of cardinal maps to emerge spontaneously. 3) Inter- and intrahemispheric long-range connections might serve as a grid preparing primary visual cortex for likely junctions in a larger visual environment encompassing the two hemifields.
