A influência do feedback verbal na cooperação em crianças

Human cooperation is a hallmark of this species due to its wide extension to genetically unrelated individuals and complex division of labor. It is considered an evolutionary puzzle, because the theory of evolution by natural selection predicts that self-interested individuals tend to be selected. Different theories have been proposed to explain the evolution of cooperation, which the most important are kin selection and reciprocal altruism. Considering the evolutionary continuity between species, humans and other primates have several common traits that help to promote cooperation between individuals of these species. Two features, however, seem to be particularly humans: inequality aversion and preferences in relation to others. Although human cooperation is not necessarily related to morality, cooperative traits are the basis for moral tendencies. The development of human morality is a combination of early prosocial tendencies, cooperative skills displayed at different ages, social learning and cultural transmission of norms. The social stimulus seems to be particularly important in promoting cooperative behavior in children and adults. In order to study the influence of social stimuli, as verbal feedback, on children cooperation, a study was conducted with children in a public goods game. 407 children from public schools in Natal / RN, divided into 21 groups, between six and nine years, participated in eight rounds of this game. After each round, seven groups received praise for larger donations, seven groups have been criticized by smaller donations, and the other seven received no comment. Children cooperated more when criticized, without significant differences between sexes, although young children have cooperated more negative than older children. The results are likely related to the anticipation and avoidance of punishment associated with the feedback (although this did not occur), and greater sensitivity to the authority in younger children. Nevertheless, the cooperation decreased in all groups until the last day of play. The results suggest an early sensitivity to moral punishment, whose role in the maintenance of social relations must have been important in the evolution of cooperation in humans

Relações sociais de callithrix jacchus machos: competição ou cooperação?

The group Callithrichidae is characterized by the flexibility in its mating system. This fact generates questions about the mechanisms that Callithrix jacchus males reach the breeding position in a group and how they prevent the subordinates reproduction, since the competition apparently happens with less intensity when compared to the females. Studies have shown the importance of social interactions and kinship among individuals in the distribution of mating opportunities in a group. This work aimed to evaluate if dyads of Callithrix jacchus males acted socially different due to kinship. We observed the agonistic and affiliative behaviours made by the males when associated in dyads (Phase 1) and when these dyads received a female (Phase 2), which was introduced in the pair`s cage for 45 minutes. In the phase 2, we also accounted for the sexual interactions between males and female in each trio. We used 16 males, 8 related (brothers-R) and 8 nonrelated (NR), as well as 8 females. Each phase lasted 4 weeks, with 3 observations/week, during 15 min/male in phase 1 and 2. In the first phase, two pairs of R males had a contested dominance and the other two, just like in the NR males, had an uncontested dominance. The NR dominant males were more aggressive than the subordinates. With the female`s entrance in the cage, all male pairs began to have an uncontested dominance. The NR males aggression frequency rose along with the subordinates` submission. In the R males, the frequency of grooming and physical contact was higher than in the NR males. So, we conclude that the low levels of agonism presented by the R males, along with the higher tolerance shown amongst them, lead us to believe that kinship attenuate the competition among these males

O cotidiano do(a) Assistente Social frente as demandas apresentadas pela paciente portadora do câncer de mama em tratamento no Hospital Doutor Luiz Antônio em Natal/RN

This work deals with an analysis related to the social worker s practice in the oncology area. It aims to identify demands, work conditions as well as current challenges related to this profession. It considers the specificities of breast cancer and relates it to political decisions in the health sector considering the concept of contemporary capitalism. The study analyzes professional action and the demands presented by breast cancer patients who are currently in treatment in Hospital Dr. Luiz Antônio em Natal-Rio Grande do Norte-Brazil. The methodological procedures considered of documental analysis, semi-structured interviews (with two social workers that work with fifteen breast cancer patients) as well as participant observation; which was done counting with my own professional practice in the oncology area. Thus, the research also discusses the breast cancer issue in the life of the users considering their social-economical, cultural and political determinants. Factors such as age in which the diagnosis was known, the relation user/social workers, number of children, rights of the oncology patient, place where he/she lives, education, civil status, (re)insertion of the professional in the work field, perception of self-esteem and bio-psycho-social representation of breast cancer in the lives of these women, all of which were dealt with in this research

O circuito espacial de produção e os círculos de cooperação da soja no Maranhão no período técnico-científico informacional

The study in screen it has as objective the understanding of the space circuit of production and the circles of cooperation of the soy that if develop in the Maranhão in the technician-scientific-informational period. Characterized for the material and incorporeal flows if they develop in the Maranhão, from the moment where it had a process of integration of the maranhense territory while peripheral space of the capitalist dynamics, that if gave through the politics of regional integration created by the State, but when it had a process of selective modernization, also partial and conservative of the agriculture, that made possible the significant increase of the production and reproduction of the capital. The study sample that with the advent of the soy, had a concentration of the production techniques, mainly in the agricultural region of Balsas, due to bigger it offers of lands, time of implantation of the culture, technique accumulated in the production, whereas in the agricultural region of Chapadinha, these indices still are without representation. Moreover, the intensification of the agricultural credit, the agrarian politics and tax incentives are elements that have propitiated increase of the production of the soy. The development of the space circuit and circles of cooperation of the soy, a side, create new forces politics in the Maranhão that can result in the creation of a new state, the other, are responsible, for the elimination of part of the subsistence agriculture, producing social problems as, agrarian concentration and unemployment. The study it still evidences the appropriation of the place for a small number of companies that has generated, beyond an intense concentration of income, an alienation of the territory, in view of that this is used for a strange purpose to the place and the yearning of the population does not stop

O circuito espacial produtivo e os círculos de cooperação da carcinicultura do Rio Grande do Norte

Suponiendo que la dinámica territorial del período histórico actual se caracteriza por la nueva división territorial del trabajo, por la especialización regional productiva y por la racionalidad que preside el movimiento de las mercancías y de la información, la teoría de los circuitos espaciales de producción se convierte fundamental para la comprensión de la organización, regulación y del uso de territorios por las actividades productivas. Así, teniendo en cuenta este supuesto y aplicando esta teoría para analizar el área de la producción de camarón en el estado de Rio Grande do Norte, se llega a comprender la dinámica del territorio Potiguar. Por lo tanto, en nuestro trabajo pretendemos entender el movimiento, la secuencia de los casos que geográficos que separan la producción, distribución, intercambio y consumo de camarón Potiguar, en este momento, sobre todo a partir de la década de 1990, sucede la expansión del cultivo de camarón en la costa norte Riograndense. La investigación ha demostrado que a pesar de la presencia de un gran número de agentes en la actividad, hay un control y una concentración del circuito en las manos de grandes empresas. Este control se pasa por el reducido número de agentes de venta de larvas, alimentación, maquinaria e insumos. Y con respecto a la concentración, esto ocurre sobre todo en la etapa de producción en las haciendas de engorde. En este caso, podemos decir que hay un predominio de los pequeños productores en números absolutos en el cultivo de camarón potiguar, ya que gran parte de los emprendimientos tienen dimensiones inferiores a 10 ha. Sin embargo, cuando analizamos las empresas de gran escala, éstos, a pesar de representar un porcentaje menor del total, concentran casi la mitad de las áreas cultivadas, además de tener en el control de gran parte del movimiento establecido por el circuito espacial productivo de la producción de camarón. Así, aparecen en el circuito espacial productivo de la producción de camarón de Rio Grande do Norte, las diferencias cualitativas de los usos del territorio entre los agentes que participan de este circuito. Porque un número limitado de agentes tienen las mayores áreas productivas, son dotados de un mayor nivel de tecnificación y tienen, hasta cierto punto, el control del movimiento de su producto, mientras que, eso no se reproducen por otros agentes, especialmente aquellos dedicados a la producción, efectiva, en las haciendas de engorde
