Cidadania e retóricas negras de inclusão social

A formação das classes sociais brasileiras de certo modo coincidiu com as hierarquias herdadas da colonização: os povos anteriormente conquistados ou escravizados, que passaram a ser definidos por meio da classificação por raças, nesse processo tornaram-se também subalternos. A extensão de direitos iguais para todos os membros da nação se constituiu igualmente de forma peculiar. Neste artigo, eu exploro o modo pelo qual as hierarquias sociais se mantiveram e se reproduziram no contexto em que a liberdade individual foi a base para a formação nacional, assim como a maneira com que os anseios históricos de liberdade cederam lugar, na motivação dos ativistas negros, à igualdade de oportunidades.

Social learning and action understanding in human observers: contributions of sensori-motor constraints and prior information

The aim of this thesis was to investigate the respective contribution of prior information and sensorimotor constraints to action understanding, and to estimate their consequences on the evolution of human social learning. Even though a huge amount of literature is dedicated to the study of action understanding and its role in social learning, these issues are still largely debated. Here, I critically describe two main perspectives. The first perspective interprets faithful social learning as an outcome of a fine-grained representation of others’ actions and intentions that requires sophisticated socio-cognitive skills. In contrast, the second perspective highlights the role of simpler decision heuristics, the recruitment of which is determined by individual and ecological constraints. The present thesis aims to show, through four experimental works, that these two contributions are not mutually exclusive. A first study investigates the role of the inferior frontal cortex (IFC), the anterior intraparietal area (AIP) and the primary somatosensory cortex (S1) in the recognition of other people’s actions, using a transcranial magnetic stimulation adaptation paradigm (TMSA). The second work studies whether, and how, higher-order and lower-order prior information (acquired from the probabilistic sampling of past events vs. derived from an estimation of biomechanical constraints of observed actions) interacts during the prediction of other people’s intentions. Using a single-pulse TMS procedure, the third study investigates whether the interaction between these two classes of priors modulates the motor system activity. The fourth study tests the extent to which behavioral and ecological constraints influence the emergence of faithful social learning strategies at a population level. The collected data contribute to elucidate how higher-order and lower-order prior expectations interact during action prediction, and clarify the neural mechanisms underlying such interaction. Finally, these works provide/open promising perspectives for a better understanding of social learning, with possible extensions to animal models.

Effectiveness of an Online Social Constructivist Mathematical Problem Solving Course for Malaysian Pre-Service Teachers

This study assessed the effectiveness of an online mathematical problem solving course designed using a social constructivist approach for pre-service teachers. Thirty-seven pre-service teachers at the Batu Lintang Teacher Institute, Sarawak, Malaysia were randomly selected to participate in the study. The participants were required to complete the course online without the typical face-to-face classes and they were also required to solve authentic mathematical problems in small groups of 4-5 participants based on the Polya’s Problem Solving Model via asynchronous online discussions. Quantitative and qualitative methods such as questionnaires and interviews were used to evaluate the effects of the online learning course. Findings showed that a majority of the participants were satisfied with their learning experiences in the course. There were no significant changes in the participants’ attitudes toward mathematics, while the participants’ skills in problem solving for “understand the problem” and “devise a plan” steps based on the Polya’s Model were significantly enhanced, though no improvement was apparent for “carry out the plan” and “review”. The results also showed that there were significant improvements in the participants’ critical thinking skills. Furthermore, participants with higher initial computer skills were also found to show higher performance in mathematical problem solving as compared to those with lower computer skills. However, there were no significant differences in the participants’ achievements in the course based on gender. Generally, the online social constructivist mathematical problem solving course is beneficial to the participants and ought to be given the attention it deserves as an alternative to traditional classes. Nonetheless, careful considerations need to be made in the designing and implementing of online courses to minimize problems that participants might encounter while participating in such courses.

Skills training and social influences for violence prevention in middle schools: A curriculum evaluation

This pilot study evaluated the effect of skills training and of social influences on self-reported aggressive behavior in a sample of 239 sixth-grade students. The effect of two intervention groups and one control group were compared. In the first intervention group, a 15-session, violence-prevention curriculum was taught by the teacher. In the second intervention group, the same curriculum was taught by the teacher with the assistance of peer leaders trained to modify social norms about violence. The control group was evaluated but did not receive any training. The design included four schools. In two schools, three classes were assigned to one of the two interventions or to the control group. In the other two schools, two classes were assigned to either intervention (teacher only) or control. Students were evaluated before and after the implementation of the curriculum using a standardized questionnaire.^ The primary outcome was the effect of the curriculum and peer leaders on self-reported aggressive behaviors. The secondary outcome was their impact on intervening variables: knowledge about violence, conflict-resolution skills, self-efficacy, and attitudes.^ The intervention had a moderate effect on reducing self-reported aggressive behaviors among boys in two of the six classes that received the curriculum. Both classes with peer leaders reduced their aggressive behavior, but this reduction was significant in only one. A peer leader selection problem could probably explain this lack of effect.^ In three of the four schools, both interventions had an overall significant effect on increasing knowledge about violence and skills to reduce violence. Students also developed a more negative attitude toward violence after the intervention. As hypothesized, attitude change was stronger among students from the teacher plus peer leader group. No intervention effect was observed on self-efficacy nor on attitudes toward skills to reduce violence. Limitations of the study and implications for violence prevention in schools are discussed. ^

Social Inequality in Political Participation: The Dark Sides of Individualisation

Has the participatory gap between social groups widened over the past decades? And if so, how can it be explained? Based on a re-analysis of 94 electoral surveys in eight Western European countries between 1956 and 2009, this article shows that the difference in national election turnout between the half of the population with the lowest level of education and the half with the highest has increased. It shows that individualisation – the decline of social integration and social control – is a major cause of this trend. In their electoral choices, citizens with fewer resources – in terms of education – rely more heavily on cues and social control of the social groups to which they belong. Once the ties to these groups loosen, these cues and mobilising norms are no longer as strong as they once were, resulting in an increasing abstention of the lower classes on Election Day. In contrast, citizens with abundant resources rely much less on cues and social control, and the process of individualisation impacts on their participatory behaviour to a much lesser extent. The article demonstrates this effect based on a re-analysis of five cumulative waves of the European Social Survey.

Social stratigraphy in Late Iron Age Switzerland: Stable carbon, nitrogen and sulphur isotope analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them C3 plants were found to be the staple food. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society.

Social stratigraphy in Late Iron Age Switzerland: Analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved and were investigated anthropologically. Collagen was analysed via stable isotope mass spectrometry (carbon, nitrogen, and sulphur). Additionally, some bones showed pathologies or lesions which were examined via imaging and histological methods. The aim of the study was to obtain biological-anthropological information about the Iron Age population. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society. Also, skull trepanations in two males suggest that surgical treatment of injuries caused by weapons may have been performed.

Mistreatment and self-neglect in community dwelling older adults: Studies of construct validity, measurement invariance and latent classes

Mistreatment and self-neglect significantly increase the risk of dying in older adults. It is estimated that 1 to 2 million older adults experience elder mistreatment and self-neglect every year in the United States. Currently, there are no elder mistreatment and self-neglect assessment tools with construct validity and measurement invariance testing and no studies have sought to identify underlying latent classes of elder self-neglect that may have differential mortality rates. Using data from 11,280 adults with Texas APS substantiated elder mistreatment and self-neglect 3 studies were conducted to: (1) test the construct validity and (2) the measurement invariance across gender and ethnicity of the Texas Adult Protective Services (APS) Client Assessment and Risk Evaluation (CARE) tool and (3) identify latent classes associated with elder self-neglect. Study 1 confirmed the construct validity of the CARE tool following adjustments to the initial hypothesized CARE tool. This resulted in the deletion of 14 assessment items and a final assessment with 5 original factors and 43 items. Cross-validation for this model was achieved. Study 2 provided empirical evidence for factor loading and item-threshold invariance of the CARE tool across gender and between African-Americans and Caucasians. The financial status domain of the CARE tool did not function properly for Hispanics and thus, had to be deleted. Subsequent analyses showed factor loading and item-threshold invariance across all 3 ethnic groups with the exception of some residual errors. Study 3 identified 4-latent classes associated with elder self-neglect behaviors which included individuals with evidence of problems in the areas of (1) their environment, (2) physical and medical status, (3) multiple domains and (4) finances. Overall, these studies provide evidence supporting the use of APS CARE tool for providing unbiased and valid investigations of mistreatment and neglect in older adults with different demographic characteristics. Furthermore, the findings support the underlying notion that elder self-neglect may not only occur along a continuum, but that differential types may exist. All of which, have very important potential implications for social and health services distributed to vulnerable mistreated and neglected older adults.^

As culturas juvenis como campo de distinção social e de disputas simbólicas

Este trabalho sistematiza resultados de uma pesquisa sobre jovens de camadas populares em relaçao às redes de sociabilidades e aos processos de formaçao a que estao referidos como agentes que se movimentam em espaços urbanos marcados pela exclusao. Os jovens pesquisados sao moradores da Regiao Leste de Goiânia (Goiás, Brasil), estudantes ou evadidos da escola, oriundos de famílias que possuem uma experiência recente de escolarizaçao e de pais que exercem ocupaçoes profissionais de natureza manual. Considera-se que a questao dos jovens nas sociedades contemporâneas tem assumido significativa relevância em estudos e pesquisas recentes, sobretudo porque os processos sócio-econômicos-culturais em curso nessas sociedades apresentam novos desafios para esse grupo etário e, por conseguinte para as instituiçoes formadores que trabalham com esse agentes. Fundamentando-se na perspectiva teórica de Bourdieu, Raymond Williams e Paul Willis, entende-se que a constituiçao dos universos socioculturais juvenis realiza-se por um amplo leque de diversidades diante das condiçoes materiais e simbólicas vividas: de agrupamento e organizaçao, classes sociais, diferenças étnicas e religiosas, peculiaridades regionais e de gênero

Diferenciación social campesina y señorío episcopal. Zamora, siglos XI-XIII

El presente trabajo indaga acerca de los procesos de diferenciación social campesina temprana en la Zamora medieval. Dicho proceso adquiere características particulares de acuerdo al marco señorial en que se inserten las comunidades. La documentación zamorana ha permitido agrupar los casos empíricos en dos tipos ideales, aquellos que presentan desarrollo de caballería y los que maduran al interior de cotos de abadengo. En cuanto al primer tipo, comprobamos que la caballería que surge de las propias clases campesinas tiende a transformarse en un sector privilegiado en la comunidad. Tal proceso de diferenciación se presenta con importantes disparidades evolutivas en las distintas comunidades. Las comunidades de este tipo que ingresan a la órbita episcopal evidencian conflictos violentos relacionados con la imposición de nuevos derechos señoriales y nuevas pautas de reproducción señorial. En cambio, en las aldeas desarrolladas desde su inicio al interior de cotos monásticos la diferenciación por el ejercicio de la función militar se encuentra negada. La única posibilidad estructural de diferenciación se relaciona con el ejercicio de funciones en representación del señor. El surgimiento de tales sectores evoluciona, entonces, de manera coherente con la construcción del poder señorial a escala local. En las comunidades con presencia de caballería será necesario desmontar las jerarquías preexistentes, proceso que determina que únicamente bien entrado el siglo XIII puedan comenzar a esbozarse nuevas elites locales y condiciones de poblamiento afines a la reproducción del señorío eclesiástico.

Medio ambiente social y cultural : Análisis de los enunciados de las clases de Educación Física

El análisis de las acciones verbales que tienen lugar en las clases proporciona información sobre las prácticas docentes. Los seres humanos contamos con el lenguaje como herramienta fundamental para comunicarnos y construir conocimiento. La reflexión sobre su uso, concretamente el uso que los docentes hacen de este instrumento netamente humano en sus prácticas, es esencial para acrecentar nuestro conocimiento acerca de la tarea docente.
Desde el área de la Didáctica de la Lengua y los enfoques teóricos de la Teoría de la actividad (Leontiev, 1983) y el Interaccionismo socio-discursivo (Bronckart, 1997/2004, 2007), emprendemos este trabajo que se circunscribe al material resultado de las observaciones de clases de Educación Física de nivel primario de escuelas públicas de San Carlos de Bariloche (Río Negro-Argentina). La metodología consiste en convertir los textos orales de las clases en registros escritos para estudiar su organización interna según tres niveles superpuestos, tal como Bronckart (1997/2004) plantea. El resultado es un trabajo de corte cualitativo en el que se estudian en profundidad los contenidos actitudinales presentes en las clases.
Nuestro objetivo es estudiar las interacciones docente-alumnos en el medio social áulico para determinar a través de qué actividades los docentes propiciamos el desarrollo de nuestros alumnos. Es decir, analizar cómo a través de los enunciados de los docentes, se construye el medio ambiente social y cultural (Voloshinov, 1992; Riestra, 2011) en las clases de Educación física.

La educación secundaria como una demanda social bajo el primer peronismo. Un estudio de caso : El Colegio Nacional Mixto de Morón (1949-1955)

El artículo analiza la fundación de un Colegio Nacional en el distrito de Morón en el año 1949 bajo los designios del llamado primer peronismo (1946-1955). Da cuenta de un conjunto de aspectos que van desde la cuestión política encarnada en la centralización del sistema de enseñanza y la cuestión social, es decir, la demanda por una democratización del nivel secundario junto con los límites y falencias del sistema en un contexto caracterizado por el ascenso de las clases medias urbanas y la politización de la educación

Questões sobre Classes, Dominação e Conflitos Sociais na Alta Idade Média

Except for a History that is mobilized, nowadays, much more by the supposedly continuities than the changes, the periods of major transitions continue to demand interpretative effort from specialists. It is long the list of those who have been dedicated to the transitional problem between the Antiquity and the Middle Ages, focused on a period of poor and unequally distributed sources, trying to shed light and establish various interpretative means for this phenomenon. Albeit having overcome some of the catastrophic perspectives hindering the pioneer analyses within this context, the current approaches have also eliminated the recognition of both the contradictory manifestations and the social struggles acting as central and fundamental engines of the social transformations within the discussed context. When supported by an adequate theoretical background, documents from the period lead us to a process resulting from contradictions and a scenario of actions and reactions that eventually materialized the conflicts and moved History forward. The transition from the Antiquity to the Middle Ages was encompassed by diverse social antagonist manifestations, which allows us to consider that the arena of disputes were, therefore, that of the society itself.
