Social structure emerges via the interaction between local ecology and individual behaviour.

1. The formation of groups is a fundamental aspect of social organization, but there are still many questions regarding how social structure emerges from individuals making non-random associations. 2. Although food distribution and individual phenotypic traits are known to separately influence social organization, this is the first study, to our knowledge, experimentally linking them to demonstrate the importance of their interaction in the emergence of social structure. 3. Using an experimental design in which food distribution was either clumped or dispersed, in combination with individuals that varied in exploratory behaviour, our results show that social structure can be induced in the otherwise non-social European shore crab (Carcinus maenas). 4. Regardless of food distribution, individuals with relatively high exploratory behaviour played an important role in connecting otherwise poorly connected individuals. In comparison, low exploratory individuals aggregated into cohesive, stable subgroups (moving together even when not foraging), but only in tanks where resources were clumped. No such non-foraging subgroups formed in environments where food was evenly dispersed. 5. Body size did not accurately explain an individual's role within the network for either type of food distribution. 6. Because of their synchronized movements and potential to gain social information, groups of low exploratory crabs were more effective than singletons at finding food. 7. Because social structure affects selection, and social structure is shown to be sensitive to the interaction between ecological and behavioural differences among individuals, local selective pressures are likely to reflect this interaction.

Science and the values of popular movements

First an overall view is provided of Lacey’s ideas concerning science in its relation with the values of popular movements, and of the World Social Forum. Then, as an exercise in the building of conceptual bridges betweeen philosophical and political discourses about science, an analysis is provided of a speech delivered by Brazil’s new minister for science and technology in the occasion of his taking office.

Self-organized sociopolitical interactions as the best way to achieve organized patterns in human social systems: going beyond the top-down control of classical political regimes

La monografía presenta la auto-organización sociopolítica como la mejor manera de lograr patrones organizados en los sistemas sociales humanos, dada su naturaleza compleja y la imposibilidad de las tareas computacionales de los regímenes políticos clásico, debido a que operan con control jerárquico, el cual ha demostrado no ser óptimo en la producción de orden en los sistemas sociales humanos. En la monografía se extrapola la teoría de la auto-organización en los sistemas biológicos a las dinámicas sociopolíticas humanas, buscando maneras óptimas de organizarlas, y se afirma que redes complejas anárquicas son la estructura emergente de la auto-organización sociopolítica.

Análisis de las estrategias de gestión social en la recuperación de patrimonio cultural inmueble en centros históricos. Estudio de Caso: Bogotá, barrio La Candelaria, 2000-2010

Existen factores importantes en el deterioro del Centro Histórico de Bogotá, a saber, los crecientes movimientos poblacionales en el centro de la ciudad, las actividades de comercio que generan funciones poco constructivas para el centro histórico y la no apropiación de toda la población que hace uso de él. A partir de esta problemática se pensó algo que pareciera obvio y es que en buena parte el patrimonio además de la mención o interrogante respecto a los temas de ley tanto del Estado como del Distrito, en su facultad de dar una solución al deterioro del centro histórico, es también pensarlo desde el punto de vista de la gestión social. Entendiendo que el patrimonio no solamente se consolida o se protege pensando desde las herramientas o los recursos que promueve el Estado, sino de la gestión social misma, de aquella que los propios residentes, habitantes o usuarios del centro puedan movilizar.

La salud y la promoción de la salud: una aproximación a su desarrollo histórico y social

Dado que el concepto de salud-enfermedad puede ser abordado desde diversas perspectivas teóricas, en este apartado se presentan de manera sucinta los principales enfoques que se han desarrollado en torno a éste, con la intención de identificar sus alcances. Se busca evidenciar las perspectivas conceptuales de la salud y la promoción de la salud, como un hecho histórico circunscrito y afectado por una realidad social, y en esa medida constructoras no sólo de un saber, sino también de una práctica institucional, que determina los diferentes movimientos desde los cuales las comunidades se dirigen hacia modos de entender y manejar su salud, lo cual no quiere decir que los individuos y colectivos, como seres históricos y activos, no ejerzan de manera autónoma sus propias convicciones y decisiones frente al curso de su vida.

Estudio de caso: La Marcha Patriótica como movimiento social y político: Análisis de la naturaleza de un actor en construcción a partir de su accionar y sus reivindicaciones. 2010 - 2012.

La presente investigación tiene como objetivo realizar una aproximación interpretativa a la Marcha Patriótica [MP] a través de tres ejes, a saber, Partido Político, Movimiento Político y Movimiento Social. Para desarrollarlo, se realizó una caracterización del contexto con el interés de identificar las situaciones contributivas a la génesis de la MP. En este contexto, se logró establecer que la situación más importante y determinante fueron los diálogos de paz de La Habana entre el gobierno de Colombia y la guerrilla de las Fuerzas Armadas Revolucionarias de Colombia. Posteriormente, se realizó la descripción de los tres ejes de interpretación y la definición de cómo serían entendidos para efectos del estudio de caso. Finalmente, se procedió con una caracterización de la MP a través de los ejes y se concluyó con una explicación amplia que dio como resultado la incorporación de nuevos elementos de análisis. Lo anterior, permitió explicar a la MP a partir de sus sectores, sus reivindicaciones, su accionar, los movimientos que la componen y los actores con los que se relaciona.

Memory and power : two movements

The institutions that work with the preservation and diffusion of cultural heritage - be them archive, libraries, museums, art galleries or cultural centres - present a certain discourse about reality. To understand this discourse, composed by sound and silence, by fullness and emptiness, by presence and absence, by remembrance and forgetting, an operation is implied, not only with the enunciation of speech and its gaps, but also the comprehension of that which causes to speak, of who is speaking and of the point whence one speaks. Preservation and destruction, or, in another way, conservation and loss, walk hand in hand in the arteries of life. As suggested by Nietzsche (1999, p.273), it is impossible to live without loss, it is entirely impossible to live avoiding destruction to play its game and drive the dynamics of life on. However, by means of a kind of tautological argument, one often justifies preservation by the imminence of loss and memory by the threat of forgetting. Thus, one ceases to consider that the game and the rules of the game between forgetting and memory are not fed by themselves and that preservation and destruction are not opposed in a deadly duel, but instead they complement one another and are always at the service of subjects that build themselves and are built through social practices. To indicate that memories and forgettings can be sown and cultivated corroborates the importance of working towards the denaturalisation of these concepts and towards the understanding that they result from a construction process also involving other forces, such as: power. Power is a sower, a promoter of memories and forgettings.

Oxytocin increases eye contact during a real-time, naturalistic social interaction in males with and without autism

Autism spectrum conditions (autism) affect ~1% of the population and are characterized by deficits in social communication. Oxytocin has been widely reported to affect social-communicative function and its neural underpinnings. Here we report the first evidence that intranasal oxytocin administration improves a core problem that individuals with autism have in using eye contact appropriately in real-world social settings. A randomized double-blind, placebo-controlled, within-subjects design is used to examine how intranasal administration of 24 IU of oxytocin affects gaze behavior for 32 adult males with autism and 34 controls in a real-time interaction with a researcher. This interactive paradigm bypasses many of the limitations encountered with conventional static or computer-based stimuli. Eye movements are recorded using eye tracking, providing an objective measurement of looking patterns. The measure is shown to be sensitive to the reduced eye contact commonly reported in autism, with the autism group spending less time looking to the eye region of the face than controls. Oxytocin administration selectively enhanced gaze to the eyes in both the autism and control groups (transformed mean eye-fixation difference per second=0.082; 95% CI:0.025–0.14, P=0.006). Within the autism group, oxytocin has the most effect on fixation duration in individuals with impaired levels of eye contact at baseline (Cohen’s d=0.86). These findings demonstrate that the potential benefits of oxytocin in autism extend to a real-time interaction, providing evidence of a therapeutic effect in a key aspect of social communication.

Social organization of marine Tucuxi dolphins, Sotalia guianensis, in the Cananeia Estuary of southeastern Brazil

Social organization is an important component of the population biology of a species that influences gene flow, the spatial pattern and scale of movements, and the effects of predation or exploitation by humans. An important element of social structure in mammals is group fidelity, which can be quantified through association indices. To describe the social organization of marine tucuxi dolphins (Sotalia guianensis) found in the Cananeia estuary, southeastern Brazil, association indices were applied to photo-identification data to characterize the temporal stability of relationships among members of this population. Eighty-seven days of fieldwork were conducted from May 2000 to July 2003, resulting in direct observations of 374 distinct groups. A total of 138 dolphins were identified on 1-38 distinct field days. Lone dolphins were rarely seen, whereas groups were composed of up to 60 individuals (mean +/- 1 SD = 12.4 +/- 11.4 individuals per group). A total of 29,327 photographs were analyzed, of which 6,312 (21.5%) were considered useful for identifying individuals. Half-weight and simple ratio indices were used to investigate associations among S. guianensis as revealed by the entire data set, data from the core study site, and data from groups composed of <= 10 individuals. Monte Carlo methods indicated that only 3 (9.3%) of 32 association matrices differed significantly from expectations based on random association. Thus, our study suggests that stable associations are not characteristic of S. guianensis in the Cananeia estuary.

A conversão de D. José Brandão de Castro : a ação social de mediadores religiosos na Diocese de Propriá

This dissertation looked for to study the charisma of the religious mediator us " Movements of Christianity of Liberation " in the Diocese Sergipana of Propriá, during the decade from sixty to eighty. Centering our debate in the understanding of the social action, we have as main subject to understand the " poor " influence in the adoption of actions on the part of the mediators, in that public's favor, mainly in Fazenda Betume conflicts (1974) and of Santana dos Frades (1979). The hypotheses, we became pregnant that the mediators as D. José Brandão de Castro and the nun Maria Joana Hermínia exercised an important influence in the construction of the identity of the movements as CEBs, MEB and CPT in the area. Such influence was motivated by a conversion of the mediator D. Brandão, constituted starting from a relationship maintained between him and the members of the movements and proportionate for the critics and demands done by the popular ones. They resulted in actions in favor of the rural ones, what characterized the Church of Propriá as allied of the involved in the conflicts and no mere middleman. Before the collected material, we made use of the Analysis of Content using the poor " term " as analysis category, complemented by interviews done to members of the mentioned movements. Esta dissertação buscou estudar o carisma do mediador religioso nos “Movimentos de Cristianismo de Libertação” na Diocese Sergipana de Propriá, durante a década de sessenta a oitenta. Centrando nosso debate na compreensão da ação social, temos como questão principal entender a influência dos “pobres” na adoção de ações por parte do mediador, em favor desse público, principalmente nos conflitos da Fazenda Betume (1974) e de Santana dos Frades (1979). Como hipóteses, concebemos que os mediadores como D. José Brandão de Castro e a freira Maria Joana Hermínia exerceram uma importante influência na construção da identidade dos movimentos como as CEBs, o MEB e a CPT na região. Tal influência foi motivada por uma conversão do mediador D. Brandão, constituída a partir de uma relação mantida entre ele e os membros dos movimentos e proporcionada pelas críticas e demandas feita pelos populares. Elas resultaram em ações em favor dos campesinos, o que caracterizou a Igreja de Propriá como aliada dos envolvidos nos conflitos e não mera intermediária. Ante o material coletado, fizemos uso da Análise de Conteúdo utilizando o termo “pobre” como categoria de análise, complementada por entrevistas feitas à membros dos movimentos citados.

Franquias sociais: minimizando riscos no investimento social

o interesse pela responsabilidade social nos últimos anos, quer como conceito ou prática, vem crescendo à medida que os problemas sociais eclodem e aumentam as expectativas de contribuição das organizações como uma parceria qualificada. Nesse contexto, o segmento empresarial vem se deparando com pressões advindas de movimentos de defesa do consumidor, campanhas de combate à miséria e a fome, além de outros que surgem com o recrudescimento de temas de minorias excluídas da vida social. Diante deste quadro as empresas estão incorporando a responsabilidade social aos objetivos de seus negócios como um fator de diferenciação no mercado e para promover benefícios sociais de grande relevância. Este estudo enfoca a responsabilidade social empresarial e a alternativa de utilização de metodologia semelhante a das franquias comerciais, as franquias sociais, para a prática das ações sociais nas empresas cearenses. A abordagem da investigação é predominantemente qualitativa e parte de uma revisão bibliográfica sobre a temática em foco, procurando compreender suas interações e incorporações nas práticas empresariais. A pesquisa considerou o universo de 32 empresas que concorreram ao "Premio Delmiro Gouvêa" , edição 2003, das maiores e melhores empresas do Estado do Ceará. A amostra corresponde a 22 dessas organizações onde as informações foram disponibilizadas. Os resultados encontrados produzem evidências que a metodologia das Franquias Sociais tem uma percepção positiva por parte do empresariado e novos estudos, sobre a temática, devem ser conduzidos com o intuito da construção de um referencial teórico mais abrangente que o ora disponível.

Jogos Pan-Americanos de 2007: uma avaliação social

O presente estudo objetivou verificar até que ponto os impactos e o legado da implementação dos Jogos Pan-americanos de 2007 alteraram as condições sociais e a forma de utilização do espaço urbano na cidade do Rio de Janeiro. Considerou-se que a competição das Américas esteja inserida na aplicação dos conceitos da cidade global, uma vez que os festivais esportivos internacionais se transformaram em megaeventos na esteira da consolidação do pensamento do planejamento urbano competitivo. Para contextualizar essa análise foi necessária uma pesquisa sobre a trajetória urbana da cidade-sede na interseção dos dois movimentos: cidade global e megaeventos. Tendo em vista que a decisão da realização do megaevento carioca foi tomada pela esfera pública, assim como o seu financiamento, foram analisados os gastos estatais e reclassificados, segundo a metodologia de O‟Connor (1977), e divididos nas funções de acumulação e de legitimação com o intuito de identificar os favorecidos e os desfavorecidos pela política pública efetivada. Os resultados da investigação sinalizam um aprofundamento da desigualdade social e urbana, via transferências de recursos públicos para o domínio do capital privado

Twitter e ciberativismo: o movimento social da hashtag #ForaMicarla em Natal-RN

The spatial and temporal fluidity conditioned by the technologies of social interaction online have been allowing that collective actions of protest and activism arise every day in cyberspace - the cyber-activism. If before these actions were located in geographical boundaries, today's demands and mobilizations extrapolate the location, connect to the global, and at the same time, return to the regional through digital virtuality. Within this context of the relationship between digital technology and global flow of sociability, emerges in October 2010 the social movement of the hashtag "#ForaMicarla", which means the dissatisfaction of cibernauts from Natal of Twitter with the current management of the municipality of Natal-RN, Micarla de Sousa (Green Party). We can find in the center of this movement and others who appeared in the world at the same time a technological condition of Twitter, with the hashtag "#". Given this scenario, this research seeks to analyze how the relationship of the agents of movement hashtag "ForaMicarla", based on the principle that it was formed in the Twitter network and is maintained on the platform on a daily basis, it can create a new kind of political culture. Thus, this study discusses theoretically the importance of Twitter and movements that emerge on the platform and through it to understand the social and political demands of the contemporary world and this public sphere, which now seems to include cyberspace
