Identidade, memória e narrativas na dança de São Gonçalo do povoado Mussuca (SE)

This study deals with the participation of the dance of São Gonçalo of the Mussuca town/SE, in the process of construction of the ethnic identity among this social group. The Mussuca is a grouping recognized as afro-descendents, linked with black enslaved people in the valley of the Cotinguiba region. The collective memory functions as a drive of this linking with the past and if it makes to elaborate narratives on this descent. The objective of this study was to investigate the ways the rite went through to constitute itself as an element of ethnic representation. Internal and external agents had been identified who had participated in different contexts. By means of an ethnographic work we ve reached some aspects of the local structure social which demonstrated the contradictions through the social relations of the group. This process of ethnic autorecognition presents the kinship and the space question as definers of the social arrangements which establish its ethnic boundaries

Tornar-se, ser e viver do professorado: entre regularidades e variações identitárias

The main aim of this research has been to analyze the identity patterns of the teacher s staff of fundamental education public schools in the Metropolitan Area of Natal-RN. It sets out from the hypothesis that being a teacher within this context grows out of the regularities of a specific habitus, which, according to Bourdieu, develops into mental schemes of thought and action within a specific social group. This habitus forms the basis on which is built the social representation of being a teacher prevailing in the group, as well as the symbolic differences that typify its identity variations. Three data sources have been fundamental in building up this thesis: (a) formative essays of students graduating from a Higher Teacher s Formation Course, as well as observing some of the public defense of these essays during field work; (b) a questionnaire aimed at classifying economically, socially, and culturally a sample of public teachers of the Natal-RN county; and (c) submitting a sub-sample of this group to the process of Multiple Classification Procedures (MCP). The analysis of data was done according to the multidimensional, non-parametric statistical procedures of both the Category Content Analysis and Enunciation Analysis methods. The results of the analysis took into account an ample set of variables, its associations and implications, the cultural and social profile of the population under scrutiny, their life styles, as well as the strategies they developed in the process of becoming a teacher, and the social representation of being a teacher . We came to the conclusion that the social identity of the teachers corps, or as we prefer to say it being a teacher , is a result of a set of regularities produced by the habitus that gives social shape and meaning to the existence of the group proper. We note the existence of identity variations caused by the variables (a) educational level; and (b) mode of action in fundamental education (if these are the first or last grades where the subjects operate). However, these variations will not break the power of the regularities that give shape, meaning, and social visibility to the group. The social representation of being a teacher points to the tensions, ambiguities, and trends inherent to common sense, as well as to a strong tendency to reassign a new meaning to being a teacher. Our thesis, therefore, is that the identity configuration of the teachers corps under scrutiny is characterized by an integrative synthesis, by-product of a habitus that is superimposed, and at the same time co-exists with different identity variations

Habitus, representações sociais e construção identitária dos professores de Maracanaú

In the last three decades, the subject of the teacher's social identity has been discussed under various theoretical focuses, not only in Brazil, but also beyond our borders. In this thesis, the theme is approached starting from the theoretical proposal that has been developed by Domingos Sobrinho (1994), which is strongly based in the epistemological approach between Pierre Bourdieu’s praxiology and the Theory of the Social Representations formulated by Serge Moscovici. It presupposes that this would make it easier to apprehend the process of construction of social identity of the investigated social group. The universe of the research is constituted by teachers of the fundamental teaching of the municipal district of Maracanaú, state of Ceará, that were active in class-room work there during at least three years, and were registered or had concluded the Course of Educational Formation promoted by UECE in that municipal district. Taking into account that the teacher's social identity is a process in permanent construction, resulting of their daily experiences and of the interferences originated from of the social context, the investigative tasks were implemented in two different stages, although they complement each other. Initially, with the objective of putting in evidence the genesis of the formation of that group’s habitus, an analysis of the family and school lives of eleven teachers who participated in the course was made, using as main sources of data: thematic memorials, semi-structured interviews and observations - inside and out of the class-room – during four school semesters. In the second stage a test of free association of words was applied to 426 teachers, seeking to apprehend the structure of the social representations of family and school – a methodological strategy considered necessary to enhance and identify certain outlines of the habitus in study, besides being in agreement with the theoretical model followed. It became evident from the results that the identity of Maracanaú’s teachers is molded and transformed into a multifaceted dynamic unit that shows successes and mistakes, certainties and doubts. For instance, besides an innovative speech seeking to reassure that teaching is a profession and not a simple vocation or mission, some discourse and attitudes are identified that point to the opposite direction, extolling the school as extension of the family, defending a parental relationship with the students, and looking at certain aspects of daily school life as “sacramental”. However, in the light of science such ambiguities and incoherences are inherent to common sense discourse, where the influences of the patterns and cultural references are present in the process of identity construction of the group, which was confirmed by the research of their social representations of family and school

Sociedade, mulher e educação nos romances de Graciliano Ramos

This paper, Society, woman and education in Graciliano Ramos' novels, is a study object from the history of woman's education in the 1930 s, it is shown as a reading of woman's representation and the configuration of the Brazilian society in that period. São Bernardo, Angustia and Vidas Secas written by Graciliano Ramos (1892-1953) from Alagoas, are used here as sources associated with the reading of the Constitutions, of the Civil Code and of some presidential messages of that decade, also with the texts produced by other scholars that present some relationship within the thematic of this approach. The representation concepts and the configuration are essential for the production of this text. I run over to the configuration concept given by Chartier (1988, p.21) a definition to representation that can be understood as a relationship between a present image and an absent object that having the value of this because it is hamonized with it. I fall back upon the configuration concept given by Elias (1969) that understands it as been a social group performed by an interdependent network that occurs within individuals as a whole joined by any reason. The totality of each individual actions with each other, permeated by tension points and balance, is what characterizes each configuration; it can be a teachers and students meeting in a classroom or a friends' encounter in the bar table, for instance. The attempt of understanding woman's representation, being educated or not, the hole attributed to her in society according to her instruction degree and the way that same society saw this woman guided me through categories that were defined throughout the successive readings: gender, civil status, education, language domain, sexuality, marriage, family, ideal woman. I accomplish this reading that was possible to do - with the pretension of not having lost the relationship between history and literature nor forgotten each one peculiarities

Guiando almas femininas: a educação protestante da mulher em impressos confessionais no Brasil e em Portugal (1890-1930)

This paper treats confessional printings as a non formal space for the female education. It reflects on the importance of the woman s role to the diffusion of Protestantism in general, and its Presbyterian trend in particular, besides commenting on the proliferation of printings at the First Republic and its relation with education. In this study, Brazilian Northeastern is seen as a relevant space to the diffusion of Protestantism in Brazil; especially on what concerns the relations between Rio Grande do Norte and Pernambuco. Thereby some fountains were fundamental, as the confessional printings, that is, newspapers, magazines, prospects and other materials recollected in archives located in Natal/RN and Recife/PE, and São Paulo. It was also provided a brief incursion on Portuguese confessional printings kept in Oporto, PT. New Cultural History was chosen as theoretic-methodological guide, franchising ways inside the history of book and reading with the help of concepts like Interdependence, Social Configuration (ELIAS, 1993, 1994) and Representation (CHARTIER, 1990), considering that the survey worked out culture-manufactured products that is, intentional materials. It is well known that publishing, or better, the dissemination of printed material used to be associated to Protestants missionary practices since Reform began and, as what concerns the investigated period, in Portuguese and Brazilian lands indistinctly. Printing material in general books, booklets, fragments, as well as the press itself played a central role in divulging reformed ideas, their social options and the means of being and intervening in the world. In this regard, the confessional printings established themselves as an educative, although non schooled, informal space, but, all considered, relevant, seen that they dialogue with another important demand of that social group: formal, literate education. Because it dealt with the diffusion of a printed culture supported by the written word, it required of that group a different modus operandi: formal education. The first letters schools at first, then the high schools later represented spaces established for the circulation of printing material in order that they should be read, divulged and comprehended. This survey intends at last to take a look at Protestantism which, in this context of self-affirmation, reserved a specific place to woman by working out a non formal educational proposal disseminated by printing material. Three models were highlighted in the reformed proposal: Christian education in itself, household education, whose references of motherhood and care towards the neighbor were present and, at last, education to the public space, with emphasis on the practice of teaching. This study also offers a brief dialogue between Brazil and Portugal because, when some periodic printing, book or something like that got to be published in one margin of the Atlantic Ocean, the other margin surely was affected by that feat, received it, divulged it, corroborating the argument in support of the circulation of these printings. It was not only the same language that survived in both maritime coasts; some protestant specificities also crossed out along that sea

A palavra cantada nos espaços intersubjetivos de um centro de atenção psisossocial do município do Natal/RN

The psychiatric care and mental health are undergoing constant change over the History. The Brazilian Psychiatric Reform, which brings up the deinstitutionalization as a structuring in the restorative care process. The Reform has as one of the mainly substitutive services the Centers for Psychosocial Care (CAPS), which work from the Singular Therapeutic Project (PTS) in order to restore the autonomy and restore the dignity of users. The therapeutic workshop is some of the resources used and work several kinds of activities as: writing, handcraft, music, poetry, and so forth. This study set up to apprehend the social representations of helping of the music workshop carried out in the CAPS II east of Natal/RN, from the reports given by the participants of the workshop, using the focal group as technique. This is a descriptive exploratory study with a qualitative approach. A total of 16 users participated in four musical therapeutic workshops from April to May 2010. The study was approved by the Ethics and Research Committee of UFRN. The discursive material from the workshop was submitted to the informational resource of Analyse Lexicale par Contexte d um Ensemble de Segments de Texte, ALCESTE, and analyzed based on the Theory of Representations and the Central Core Theory. The majority of subjects were men (62.5%), single (62.5%), aged 40-49 years (37.6%) and elementary school level (56.2 %). The reports were transcribed and submitted to the classification system of ALCESTE, which elected the following categories: Category 1 - Experience in the Word Family Sung, Category 2 - Musical Experiences and Approaches, and Category 3 - Feelings and emotions evoked by music. The representation of these individuals is anchored in the experience they have with the CAPS, lived and socialized by common sense, through this particular social group workshop objectified in music therapy as a therapeutic modality enjoyable. The central core revealed the intrinsic relationship between users and the music, establishing a relationship of openness to use the same while its therapeutic use in workshops of substitute services for mental health. Peripherals elements issues are related to listen, share and experience music in the family. Intermediary Elements relate to the feelings and emotions evoked by music, given her close relationship with it. It was found in the study that music can be construed as an artifact of good therapeutic responsiveness to users, configuring it as an invigorating and enjoyable therapy, confirming the need for continuity of this activity, as well as its expansion into the service

A mídia dos outros somos nós: a experiência audiovisual do Ponto de Cultura Cinema para Todos

This research aims to identify the process of appropriation of audio visual (in digital video) for collective symbolic production (participatory video practice that expresses popular culture) in a socio-cultural context where the minorities are. Therefore, we based this study on the students‟ experience of the film and video workshops held by Cinema para Todos (Culture Point Cine for All), in Natal, RN. Culture Point is the basis of the project Programa Nacional de Cultura, Educação e Cidadania Cultura Viva (National Program of Culture, Education and Citizenship - Living Culture) of the Brazilian Ministry of Culture. In 2010, the Cine for All developed three film and video workshops in the state of Rio Grande do Norte (Northeastern of Brazil), in the municipalities of Açu, Lajes and São Gonçalo do Amarante, within a public policy project of socio-cultural inclusion. These three workshops are the focus of this empirical investigation. To support the analysis of this research we consider that the spaces of workshops are sites of the social practices origin, assuming they show the development of the changes of actions that generate new practices. In this socio-cultural context the students as interlocutors process the communicative culture mediation, where come from the logics of action (using digital video) to become a mediatic practice (video auto ethnographic). With the overall goal set and the field of investigative action delimited we considered the methodology of case study suitable for the observation of the object, because it is a phenomenon of modernity, occurring in a context of real life and with little or no control over events. Participant observation and interviews was also applied to this case study. The analytical theoretical support comes from the notion of mediation by Jesús Martín-Barbero and the concept of habitus by Pierre Bourdieu. The research found that a new way of communicating has been developing by this social group, and this reflects the technological change experienced by them. The auto ethnographic videos, short movies, reveal an allegorical trial of the mainstream media, because while they use the mainstream format, they rework the aesthetic, but without revising the history, in fact they proposing to retell the history of themselves full of colorful details and with richness of their forgotten popular culture.

Resposta comportamental e hormonal de machos não reprodutores de sagüi, callithrix jacchus, a estímulos sensoriais de filhotes não aparentados

Parental care in mammals is influenced by somatosensory stimuli from infants, such as vocalization and sight and by changes in the hormone levels of caretakers. The aim of this study was to evaluate the behavioral and hormonal responses of twelve non reproductive adult male common marmosets (Callithrix jacchus) to infant cues, vocalization recordings, sight and physical contact with newborn. Six out of twelve males had previous experience in caretaking. In article 1, adult males were exposed to newborn vocalizations for 10 minutes. On control condition no sound was presented. In article 2, males were tested on two conditions: a) Control: an empty acrylic transparent box (test box) was placed in male s cage for 15 minutes, and b) Experimental: males were exposed to newborns into a closed text box for 15 minutes. The cage was kept closed to prevented from tactile, smell and acoustic stimulation by the infant on common marmoset males. In article 3, males were exposed to an open or closed text box, which allowed or not their access to and social interaction with the infants. After each observation sessions, blood samples were collected to evaluate the cortisol levels of males. In all studies, behavioral response of adult males was significantly modified by newborns sight, vocalization and physical contact. Males approached and spent more time near the sound source and showed an increase in locomotion during sound exposure. Furthermore, males approached, smelled and spent more time near the test box when the newborn was inside it. There was no difference in behavioral pattern between experienced and non-experienced males in articles 1 and 2. In article 3, behavioral pattern of males was influence by previous caretaking experience. Experienced males recovered quicker and carried the infants more than the inexperienced ones. However, inexperienced males showed a decrease in recovery latency and an increase in carrying time after successive exposure to infants. Cortisol levels changed after exposure to infant s vocalization, especially for experienced adult males. Male hormonal profile was not affected by the sight of infants neither by their previous experienced in caretaking. The occurrence of social interaction between the caretaker and infant did not modify the hormonal profile of common marmoset males; however, as much as experienced males carried the infants their cortisol levels decreased. Thus, members of a social group or potential caretakers common marmosets exposed to sensory cues from dependent infant such as vocalization, sight, smell and physical contact, changed their behavioral and hormonal responses that are physiological modulators of parental behavior in common marmoset

Transferência de alimento aos infantes de Callithrix jacchus em uma situação de escassez de recurso alimentar

The genus Callithrix, like other marmosets, presents a cooperative breeding system, characterized by the contribution of parents and non-breeding individuals of the social group in the care of infants. This care is provided through lactation, transport, supervision of infants and food transfers. In this study, we investigated the care of offspring in Callithrix jacchus through the food transfers in family groups under conditions of abundance and scarcity of food resources. We also attempted to verify the relationship between the participation of individuals in the transport of infants and in the food sharing. We observed four families at the Núcleo de Primatologia of the Universidade Federal do Rio Grande do Norte, in a total of seven infants, six twins and a single infant. Each infant was observed twice a week, from 1st to 20th week of life using the methods focal continuous and focal instantaneous sampling with one minute intervals. The observations were carried by 10 minutes and beginning with the supply of food for each family. Two families were tested under conditions of scarcity of food resources (experimental condition) and two others were subjected to conditions of abundant food, both conditions with restricted access to food supply. The condition of food scarcity did not influence the rate of food sharing with the infants that, in general, was considered low. All shares observed were passive sharings. Only one family showed higher levels of food begging, probably due to the loss of the mother during the period of lactation of her offspring. In this family, the dominant and subadult males were primarily responsible for the food sharing. The experimental condition influenced the distance of infants in relation to food source, so the infants in families that received abundant food remained closer to the source. However, it is believed that the place of food consumption was not influenced by experimental condition. There was no relationship between the participation of individuals in the transport and food sharing with their young. Therefore, it is suggested that, in general, the transfer of food in C. jacchus is characterized by tolerance to the demands of caregivers, represented by the passive sharing. Rates of sharing with infants were low, probably due to intra-group competition for food generated by the experiment.

Correlato hormonal do comportamento reprodutivo de machos de sagüi comum (Callithrix jacchus) em ambiente natural

Contrary to what is recorded for Callithrix jacchus females, the social interactions and hormonal profiles of males are less studied, and mainly in wild groups. The goal of this study was to investigate the behavioral and endocrine profiles of reproductive (RMs) and non-reproductive (NRs) common marmoset adult free-ranging males living in two natural groups (GC1 and GR2). The groups inhabited the area of the Escola Agrícola de Jundiaí/UFRN, located in Macaíba, Brazil. Fecal collection for cortisol and androgen measurement and behavioral monitoring was carried out during the active phase from April to September, 2005. For behavioral data collection the focal instantaneous method was used every 5 min, for a total of 11.563 records. Statistical analysis was performed using non parametric tests and p < 0.05. Besides showing diurnal variation, the frequency of affiliative behaviors was significantly higher for RMs toward reproductive females than for NRs. Affiliative interactions of RMs with both reproductive females and NRs were similar, probably related to pair bond formation and helper recruitment, respectively. Parental care was also similar for both RMs and NRs. Both androgen and cortisol levels increased after the birth of the infants, mainly in RMs. The longitudinal profile of androgens fluctuates more in response to agonistic encounters and sexual behavior than that of cortisol. The mean basal excretion of both hormones was significantly higher in RMs and seems to reflect their higher participation in territorial vigilance and mate guarding behaviors. Significant positive correlations were found between agonism and cortisol and androgen hormones. These results describe, for the first time, the behavioral and hormonal profiles of common marmosets living in free-ranging groups and suggest that reproductive males are more responsive both behaviorally and hormonally to social group dynamics
