Seasonal patterns of body temperature daily rhythms in group-living cape ground squirrels Xerus inauris

Organisms respond to cyclical environmental conditions by entraining their endogenous biological rhythms. Such physiological responses are expected to be substantial for species inhabiting arid environments which incur large variations in daily and seasonal ambient temperature (T). We measured core body temperature (T) daily rhythms of Cape ground squirrels Xerus inauris inhabiting an area of Kalahari grassland for six months from the Austral winter through to the summer. Squirrels inhabited two different areas: an exposed flood plain and a nearby wooded, shady area, and occurred in different social group sizes, defined by the number of individuals that shared a sleeping burrow. Of a suite of environmental variables measured, maximal daily T provided the greatest explanatory power for mean T whereas sunrise had greatest power for T acrophase. There were significant changes in mean T and T acrophase over time with mean T increasing and T acrophase becoming earlier as the season progressed. Squirrels also emerged from their burrows earlier and returned to them later over the measurement period. Greater increases in T, sometimes in excess of 5°C, were noted during the first hour post emergence, after which T remained relatively constant. This is consistent with observations that squirrels entered their burrows during the day to 'offload' heat. In addition, greater T amplitude values were noted in individuals inhabiting the flood plain compared with the woodland suggesting that squirrels dealt with increased environmental variability by attempting to reduce their T-T gradient. Finally, there were significant effects of age and group size on T with a lower and less variable T in younger individuals and those from larger group sizes. These data indicate that Cape ground squirrels have a labile T which is sensitive to a number of abiotic and biotic factors and which enables them to be active in a harsh and variable environment.

Prestadores de cuidados familiares a doentes com VIH/SIDA: perfil psico-emocional e social

RESUMO: Com o presente estudo pretendemos identificar a sobrecarga resultante do envolvimento familiar com os doentes portadores de VIH/SIDA. Numa breve introdução teórica, procedemos à revisão dos conceitos sobrecarga familiar e dos sentimentos/emoções vivenciados pelos prestadores de cuidados. Metodologia: Estudo do tipo descritivo e exploratório, com uma amostra de 51 indivíduos, cuja finalidade consiste na caracterização dos prestadores de cuidados familiares a doentes com VIH/SIDA. Objectivos: Identificar quem o doente com VIH/SIDA, considera ser a pessoa significativa nos cuidados informais. Caracterizar, do ponto de vista sócio-demográfico, os doentes e os prestadores de cuidados familiares. Identificar sentimentos e emoções de vivências, que justifiquem o sofrimento emocional e as repercussões na sobrecarga familiar nos prestadores de cuidados informais. Instrumentos: Na avaliação da sobrecarga familiar, utilizámos o Questionário de Problemas Familiares”- FPQ (Family Problemas Questionnaire). Para identificação dos Acontecimentos de Vida, adoptámos a escala de Holmes e Rahe (Life Events); Para identificação do estrato social escolhemos escala de Graffar. Finalmente, para a caracterização sócio-demografica concebemos dois questionários: um dirigido aos doentes e o outro aos prestadores de cuidados informais. Conclusões: A sobrecarga da doença VIH/SIDA, nos prestadores de cuidados familiares, não é uniforme nas diferentes dimensões. A dimensão sobrecarga subjectiva é superior à objectiva. O suporte social revela-se fraco, relacionado com as perdas familiares, devidas a morte, pelas relações familiares disfuncionais, entre os membros da família, pela falta de apoio e informação dos técnicos de saúde. O sexo feminino é predominante nos cuidadores. As mães e esposas são o grau de parentesco dominante. Os solteiros são o grupo mais afectado pelo VIH/SIDA. Os cuidadores apresentam idade superior à dos doentes. O estrato social preponderante é o médio baixo e o baixo. Os familiares, apesar da atitude negativa dos doentes perante os cuidadores, mantêm-se envolvidos. Segundo a avaliação multiaxial proposta pelo DM-IV, constatámos, ao nível do eixo I, sintomatologia clínica do tipo das perturbações depressivas e perturbações da ansiedade. No eixo IV, os cuidadores evidenciam problemas psicossociais e ambientais, nomeadamente nas categorias problemas com o grupo de apoio primário, problemas relacionados como grupo social, problemas educacionais, problemas de alojamento, problemas económicos. Os problemas relacionados com o grupo de apoio primário, são os que mais parecem contribuir para os problemas psicossociais e ambientais.---------------------------------------ABSTRACT: This study wants to describe several problems as a result of the family’s relationship with HIV/AIDS patients, like overload. In a brief theoric introduction, we made a small revision about the concepts of family’s overload, and feelings or emotions that have been lived by the people who provide cares to the patients with this chronic disease. Methodology: This is a describing and exploratory study, with a sample with 51 individuals, with the aim to characterize the people inside the family who give care HIV/AIDS patients. Aim: To identify who are the most important people in informal cares from the patient perspective. To characterize, in a social-demographic point of view, patients and the people who take care of them. To identify feelings and emotions that could explain an emotional suffer, and some causes in the family burden. Means: to evaluate the family’s overload we used the Family Problems Questionnaire (FPQ). To identify life events we adopted the Holmes and Rahe scale. To identify the social stratum we used the Graffer scale. Finally to do a socio-economic characterization we did two kinds of questionnaire, the first one was directed for the patients, and the second one was chosen for the people who give care. Conclusions: The HIV/AIDS disease burden on the people who takes familiar cares isn’t uniform on several areas that we studied. The subjective overload it is superior to the objective. The social support is weak and poor, and related with family losses by dead, dysfunctional family relationships, and the lack of support and information by the medical staff. Mothers and wives are the dominant relative degree. And the singles are the major group with HIV/AIDS disease. The people who take care are usually older than the sick. The major social status is low or medium-low. The relatives keep evolved though the negative attitude of the sick. According with the evaluation multiaxial proposed by the DM-IV, in axle 1 we note clinic sintomatologic belonging to the type depressive perturbations and perturbations of the anxiety. Regarding with axle IV the caretakers show up psycho-social and environmental problems, namely on the categories: problems with the primary support group and problems related as social group, educational problems, accommodation problems and.

Rock art and social life - Revisiting the Neolithic transition in Mediterranean Iberia

This article revisits the Neolithic transition in Mediterranean Iberia taking into account an aspect usually neglected in the archaeological discourse: the rock art styles that emerged in this context. These distinct styles have been generally attributed to different populations, according to a historicist point of view that equates stylistic variability and ethnic identity. However, the recent recognition that they were developed by the same social group requires the formulation of an alternative explanation. My proposal is based on the exploration of the social context of production and consumption of the rock art, through the analysis of the patterns of location of the sites within the landscape and the definition of their archaeological context.

Reproductive conflict delays the recovery of an endangered social species

Evolutionary theory predicts that individuals, in order to increase their relative fitness, can evolve behaviours that are detrimental for the group or population. This mismatch is particularly visible in social organisms. Despite its potential to affect the population dynamics of social animals, this principle has not yet been applied to real-life conservation. Social group structure has been argued to stabilize population dynamics due to the buffering effects of nonreproducing subordinates. However, competition for breeding positions in such species can also interfere with the reproduction of breeding pairs. Seychelles magpie robins, Copsychus sechellarum, live in social groups where subordinate individuals do not breed. Analysis of long-term individual-based data and short-term behavioural observations show that subordinates increase the territorial takeover frequency of established breeders. Such takeovers delay offspring production and decrease territory productivity. Individual-based simulations of the Seychelles magpie robin population parameterized with the long-term data show that this process has significantly postponed the recovery of the species from the Critically Endangered status. Social conflict thus can extend the period of high extinction risk, which we show to have population consequences that should be taken into account in management programmes. This is the first quantitative assessment of the effects of social conflict on conservation.

Luta por reconhecimento e desigualdade social: uma análise da experiência dos catadores da Asmare em Belo Horizonte (MG)

Esta dissertação discute a dinâmica de luta dos catadores da Asmare em Belo Horizonte (MG)e seus possíveis desdobramentos em políticas públicas para esse grupo social. Parte-se da ideia de luta e conflito social, recorrendo-se às discussões de luta por reconhecimento de Axel Honneth, apontando os limites e possibilidades do uso dessa abordagem no contexto brasileiro em face da elevada desigualdade social. A investigação foi realizada a partir de um estudo de caso longitudinal, com recorte temporal de 1987 a 2010. Foram feitas entrevistas em profundidade, conversas espontâneas e observações. Como método de análise foi adotada a leitura de narrativas. A partir das múltiplas vozes presentes nas narrativas dos entrevistados, observa-se que a luta dos catadores da Asmare foi repleta de idas e vindas, contradições e conflitos. Nas narrativas dos catadores foram evidenciadas diferentes formas de desrespeitos e reconhecimento recusado, bem como expectativas morais de reconhecimento. Foram alcançadas reivindicações junto ao poder público local, como a construção de uma política de apoio ao trabalho desse grupo que, ao longo dos anos, foi passando por reconfigurações e mais recentemente por uma inflexão, que acirrou os conflitos entre poder público e Asmare.

Quem tem direito à moradia? :uma análise da política nacional de habitação e dos programas de habitação de interesse social (2003-2005)

This dissertation analyses the Brazilian housing policy of today s, focusing on the programmes in the socalled Social Interest Housing Subsystem in order to discuss to what extent the government has been able to grant housing constitutional rights in the country. The discussion is about housing policy and the principles in the country s Constitution regarding the role of housing as a social right, a right that must be granted by the state. This refers to land rent theory to understand the relationship between capital and property and the reasons why, under capitalism, housing becomes a commodity in the market. Then, it discusses the national housing policy, which emphasizes land ownership through financing, that is, via market, a process that excludes all low income population. In the conclusion, it is clear that, although government programmes cover extensively at least potentially the national territory as well as social group, subsidized housing programmes cannot be implemented in the city due to land prices because subsidy is too low. In this way, the law that grants housing rights to all Brazilian citizens is violated

Análise antropológica da socialização das crianças no contexto social das famílias no trajeto do lixo no Aurá

Este é um estudo que aborda a socialização das crianças no contexto de vida no "lixão do Aurá", sob uma perspectiva antropológica. A partir da compreensão do significado e representação do lixo, assim como de sua forma de consumo se estabelece os elos explicativos que as famílias buscam empreender para socializar as crianças. A análise do material empírico parte de restituição das trajetórias de vida das famílias que impulsionados pela extrema pobreza migraram para o estado do Pará e chegaram ao lixão. Ao se reconstituir suas redes de parentesco, se percebe a reprodução de valores e percepções nas redes de sociabilidades que permitirão às famílias inserir as crianças as diversas situações de risco, violência e trabalho, para reprodução do grupo social e sobrevivência.

Quando mudar é condição para permanecer: a escola Casa Familiar Rural e as estratégias de reprodução social do campesinato na Transamazônica (Pará-Amazônia)

Neste trabalho são analisadas as relações entre escolarização (configurada na Casa Familiar Rural) e as estratégias de reprodução das organizações sociais representativas do campesinato em interface com as famílias de agricultores na Transamazônica, frente pioneira de colonização no Oeste do Pará, particularmente no município de Medicilândia. Esta escola, pensada por estes agentes sociais e coletivos em um cenário nacional e regional de publicização dos quadros que fragilizam a agricultura de base camponesa, a partir de meados da década de 1990, tem sido instrumento da luta social. As tensões no espaço social, lidas como ‘crise da base’ e ‘crise dos sistemas de produção’, teriam desenhado simultaneamente uma ‘crise de formação’ na qual as finalidades da escola foram sendo construídas por desafios sócio-econômico e políticos. Este cenário teria constituído os jovens agricultores como categoria social, investidos da expectativa coletiva de tornarem-se, sob a mediação da CFR, técnicos agrícolas e/ou dirigentes, a fim de dar continuidade ao grupo (seja dos atores, nos campos das organizações sociais/sindicais e comunitário-religiosas; seja das famílias, na sucessão agrícola e na manutenção de sua posição social). As repercussões da CFR na condição camponesa destes jovens são analisadas a partir de dados qualitativos e quantitativos, tomando-se como referência os interesses e investimentos dos agentes sociais, das famílias, bem como as inserções sócio-profissionais no campo e/ou na cidade destes jovens após a escolarização. Os resultados da CFR, considerando-se esta escola como estratégia coletiva organizada que visa transformar para conservar o campo de lutas enquanto sistema de relações objetivas do grupo social que a constitui, revelam que a mesma tem possibilitado a permanência dos jovens agricultores no campo sob diversos arranjos em que se imbricam as relações com o campesinato, com a cidade, com o conhecimento escolar/técnico, e com uma ética de trabalho e relação com a terra/natureza “ambientalizada”. No âmbito dos grupos domésticos e da coletividade camponesa (nas quais se incluem as organizações representativas do grupo estudado), a posição social destes jovens caracteriza-se por formas de distinção social visíveis nas práticas sócio-produtivas intercedidas pelo capital escolar, bem como na posição de mediadores dirigentes e técnicos.

Fundamental Dimensions of Social Judgment: Sociability and Morality as Distinct Characteristics of Social Warmth

The present dissertation focuses on the two basic dimensions of social judgment, i.e., warmth and competence. Previous research has shown that warmth and competence emerge as fundamental dimensions both at the interpersonal level and at the group level. Moreover, warmth judgments appear to be primary, reflecting the importance of first assessing others’ intentions before determining the other’s ability to carry out those intentions. Finally, it has been shown that warmth and competence judgments are predicted by perceived economic competition and status, respectively (for a review, see Cuddy, Fiske, & Glick, 2008). Building on this evidence, the present work intends to further explore the role of warmth and competence in social judgment, adopting a finer-grained level of analysis. Specifically, we consider warmth to be a dimension of evaluation that encompasses two distinct characteristics (i.e., sociability and morality) rather than as an undifferentiated dimension (see Leach, Ellemers, & Barreto, 2007). In a similar vein, both economic competition and symbolic competition are taken into account (see Stephan, Ybarra, & Morrison, 2009). In order to highlight the relevance of our empirical research, the first chapter reviews the literature in social psychology that has studied the warmth and competence dimensions. In the second chapter, across two studies, we examine the role of realistic and symbolic threats (akin economic and symbolic competition, respectively) in predicting the perception of sociability and morality of social groups. In study 1, we measure perceived realistic threat, symbolic threat, sociability, and morality with respect to 8 social groups. In study 2, we manipulate the level and type of threat of a fictitious group and measure perceived sociability and morality. The findings show that realistic threat and symbolic threat are differentially related to the sociability and morality components of warmth. Specifically, whereas realistic threat seems to be a stronger predictor of sociability than symbolic threat, symbolic threat emerges as better predictor of morality than realistic threat. Thus, extending prior research, we show that the types of threat are linked to different warmth stereotypes. In the third and the fourth chapter, we examine whether the sociability and morality components of warmth play distinct roles at different stages of group impression formation. More specifically, the third chapter focuses on the information-gathering process. Two studies experimentally investigate which traits are mostly selected when forming impressions about either ingroup or outgroup members. The results clearly show that perceivers are more interested in obtaining information about morality than about sociability when asked to form a global impression about others. The fourth chapter considers more properly the formulation of an evaluative impression. Thus, in the first study participants rate real groups on sociability, morality, and competence. In the second study, participants read an immigration scenario depicting an unfamiliar social group in terms of high (vs. low) morality, sociability, and competence. In both studies, participants are also asked to report their global impression of the group. The results show that global evaluations are better predicted by morality than by sociability and competence trait ascriptions. Taken together the third and the fourth chapters show that the dominance of warmth suggested by previous studies on impression formation might be better explained in terms of a greater effect of one of the two subcomponents (i.e., morality) over the other (i.e., sociability). In the general discussion, we discuss the relevance of our findings for intergroup relation and group perception, as well as for impression formation.

A Social Network Analysis Of Hamadryas Baboons

The study of animal sociality investigates the immediate and long-term consequences that a social structure has on its group members. Typically, social behavior is observed from interactions between two individuals at the dyadic level. However, a new framework for studying social behavior has emerged that allows the researcher to assess social complexity at multiple scales. Social Network Analysis has been recently applied in the field of ethology, and this novel tool enables an approach of focusing on social behavior in context of the global network rather than limited to dyadic interactions. This new technique was applied to a group of captive hamadryas baboons (Papio hamadryas hamadryas) in order to assess how overall network topology of the social group changes over time with the decline of an aging leader male. Observations on aggressive, grooming, and proximity spatial interactions were collected from three separate years in order to serve as `snapshots¿ of the current state of the group. Data on social behavior were collected from the group when the male was in prime health, when the male was at an old age, and after the male¿s death. A set of metrics was obtained from each time period for each type of social behavior and quantified a change in the patterns of interactions. The results suggest that baboon social behavior varies across context, and changes with the attributes of its individual members. Possible mechanisms for adapting to a changing social environment were also explored.

Social integration, health behaviors and health status among Mexican-American women in the *southwestern United States

Using the Hispanic Health and Nutrition Examination Survey (HHANES), this research examined several health behaviors and the health status of Mexican American women. This study focused on determining the relative impact of social contextual factors: age, socioeconomic status, quality of life indicators, and urban/rural residence on (a) health behaviors (smoking, obesity and alcohol use) and (b) health status (physician's assessment of health status, subject's assessment of health status and blood pressure levels). In addition, social integration was analyzed. The social integration indicators relate to an individual's degree of integration within his/her social group: marital status, level of acculturation (a continuum of traditional Mexican ways to dominant U.S. cultural ways), status congruency, and employment status. Lastly, the social contextual factors and social integration indicators were examined to identify those factors that contribute most to understanding health behaviors and health status among Mexican American women.^ The study found that the social contextual factors and social integration indicators proved to be important concepts in understanding the health behaviors. Social integration, however, did not predict health status except in the case of the subject's assessment of health status. Age and obesity were the strongest predictors of blood pressure. The social contextual factors and obesity were significant predictors of the physician's assessment of health status while acculturation, education, alcohol use and obesity were significant predictors of the subject's assessment of health status. ^

Replanteo de una cuestión polémica : sobre la naturaleza y la causación del fin común social y del bien común político

La enunciación de la tesis de que el fin común es la causa fundamental y primera del ser y del valor de los grupos sociales podría sugerir la idea de una incursión ociosa en un tema ya solucionado. A semejante objeción cabría enfrentarla con dos órdenes de argumentos. En primer lugar, para la sociología de Max Weber, tal vez la más influyente teoría social del s. XX, el constitutivo esencial del grupo social "(asociación, Verband)", reside en la estructura de las relaciones de mando y obediencia (Wirtschaft und Gesellschaft, t. I, p. 26). De tal suerte, puede decirse que en Weber toda asociación es asociación de dominación. En segundo lugar, dentro de las escuelas que en principio aceptan el fin común como el primer principio del orden social no hay acuerdo –en especial hoy- respecto de la naturaleza y la función de ese fin; a punto tal que aparece incluso comprometida su propia especificidad de causa y de fin. Así pues, este tema esencial para la verdadera intelección de la realidad social y política dista de estar cerrado.
