Contested dominance modifies the anovulatory consequences of social subordination in female marmosets

Dominance status among female marmosets is reflected in agonistic behavior and ovarian function. Socially dominant females receive submissive behavior from subordinates, while exhibiting normal ovulatory function. Subordinate females, however, receive agonistic behavior from dominants, while exhibiting reduced or absent ovulatory function. Such disparity in female fertility is not absolute, and groups with two breeding females have been described. The data reported here were obtained from 8 female-female pairs of captive female marmosets, each housed with a single unrelated male. Pairs were classified into two groups: “uncontested” dominance (UD) and “contested” dominance (CD), with 4 pairs each. Dominant females in UD pairs showed significantly higher frequencies (4.1) of agonism (piloerection, attack and chasing) than their subordinates (0.36), and agonistic behaviors were overall more frequently displayed by CD than by UD pairs. Subordinates in CD pairs exhibited more agonistic behavior (2.9) than subordinates in UD pairs (0.36), which displayed significantly more submissive (6.97) behaviors than their dominants (0.35). The data suggest that there is more than one kind of dominance relationship between female common marmosets. Assessment of progesterone levels showed that while subordinates in UD pairs appeared to be anovulatory, the degree of ovulatory disruption in subordinates of CD pairs was more varied and less complete. We suggest that such variation in female-female social dominance relationships and the associated variation in the degree and reliability of fertility suppression may explain variations of the reproductive condition of free-living groups of common marmosets

Gestão Social em Empreendimentos Econômicos Solidários: uma abordagem no Oeste Potiguar

The central research question was to search for data to ratify the theory and discourse of the so-called practitioners of economic solidarity, by defending the substantive rationality should guide the principles of economic solidary, designing the space economy incidental and not the primacy of relations in determining social as well, reflecting the predominance of dimensions of social management in administrative practices of ESS's. For both analyzed the theoretical dimensions of social management - sociopolitical, economic, organizational and environmental - manifested in organizational practices supportive of economic organization Potiguar West. For the success of the research realized the triangulation involving a combination of quantitative and qualitative methodological approaches. At first the research will use a quantitative approach, from the cluster analysis, to verify the behavior of the sample chosen for this study. In the second stage of the qualitative study was carried out focus group technique (FLICK, 2002) for further analysis of the dimensions of social management on organizational practices supportive of economic organization, related to the principles of Solidary Economy, established in a quantitative approach. In quantitative analysis, the socio-political dimension, it was clear that the more equity instruments of internal and external, from the purposeful living in public spaces, the best monetary results. Another point worth stressing concerns the economic dimension, with the practice reciprocity prevailing in market. Thus, the qualitative approach was possible to understand the processes of exchange of product or service. Rural enterprises surveyed in the allocation of the agro-ecological products have the following scale of priority, sequentially: self-consumption (domestic), market and exchange. The research leads to the fact that training and practices that enhance the socio-political dimension (knowledge, empowerment, sense of belonging) become the guiding principle for the strengthening of the social management in the context of other dimensions, leading to gains sociopolitical, economic, organizational and environmental. Despite the weaknesses found in the organizational dimension and environment, both in a quantitative as in qualitative, we determined that the practices of ESS's Potiguar West incorporate predominantly elements of social management and economic solidarity, with a preponderance of substantive rationality in the primacy of the instrumental. Finally, research has brought information that the participants of the ESS's do not give the money economy primacy in determining social relations, which in turn leads to the confirmation that, in practice the solidarity economy, prevailing the dominance of substantive rationality, as a guide for organizational practices

Comportamento social e territorialidade alimentar na garça-azul, Egretta caerulea (L) = Feeding territoriality in the little blue heron, Egretta caerulea (L)

The use of habitat is an important part of a species biology. One resource of great importance for the survivor and reproduction of an individual is the food resource. Thus, the social interactions an animal has during the feeding activities are of extremely importance within its behavioral aspects, which represents the part of an organism trough which it interacts with the environment, adapting to changes and variations. Herons are known to form feeding aggregations of even more than thousands of individuals, in which social components of foraging have been identified and studied for several species. More profound studies of these aspects are yet to poor for the Little Blue Heron, Egretta caerulea. Therefore, the aim of this study was to describe the social behavior (display postures, vocalizations and co-specific interactions) and the territoriality of the specie during the feeding period in an area of mud bank in the estuarine system of Cananéia, south coast of São Paulo state, Brazil. The defense of a fixed and exclusive area, closest to the mangrove, trough expulsion was observed; some thing that have not yet been registered with concrete data for the specie. Higher capture and success rates, and lower investment rates (steps/min and stabs/min) were registered for individuals foraging in areas corresponding to the defended territory. This could be one of possible reasons for the establishment of territories in the area. Four display postures were registered for the specie, two of then new in the literature, which are used in the interactions between individuals; one vocalization, that apparently is important in the social context of foraging for the specie and, possibly, has a function of advertising and proclaiming the dominance position of the territorial individual within the group. A territorial individual uses three behaviors, of the ones described: expulsion, vocalization and encounter (agonistic encounter between individuals, without physical aggression). Of these, the expulsion is apparently used in the actual defense, actively; while the other two behaviors are used in a more passive way, in the maintenance of the dominance position of the individual, helping it in the defense of its territory in a less direct manner. Therefore, with the results presented in here, new components of the social utilization of the feeding resource for the Little Blue Heron were identified, incorporating aspects of the territorial behavior for a future understanding of its possible adaptive significance. And it also reinforces the importance of the social interactions of herons foraging in great aggregations, in areas ecologically important

Hierarquia social e sucesso alimentar em callithrix jacchus (Primates, Callithrichidae), sob condições naturais

The competition for resources is one of the costs of group living. The scramble competition is considered an indirect type of competition, mainly associated with factors like group size and distribution of resources. Contest competition occurs when individuals compete directly for resources. In species that exibit this type of competition the establishment of dominance hierarchy can occur, resulting in differences on feeding and reproductive benefits for each member of the group. In these cases, aggressive and submissive behaviors are expected as a way to signal social status. The aim of this study was to investigate the effects of social hierarchy over food ingestion in Callithrix jacchus. Data recording was from September/2006 to March/2007, eight days by month, at Floresta Nacional de Açu do Instituto Chico Mendes de Biodiversidade. The observation time started at 05:00 AM and finished after the last animal was on the sleeptree. Analyses of aggressive interactions, behavioral profile and diet, reveals a lot of advantages for dominat animals in the study group. Dominant individuals had higher intake of animal matter that subordinates. The last ones, consumed fruits, exsudate and, eventually, explored itens that were not common to the diet. We suggest that dominance hiearchy enable the reproductive female to assure priority on access to food resources, a important caracteristc to supply tha costs to maintain tha high reproductive taxa of the specie. We also suggest that reproductive male, due to the participation on food transfer, had the forage efficience reduced

Violência contra a mulher:uma análise do trabalho do Centro de Referência da Assistência Social-CREAS/Parnamirim-RN.

This work demonstrates the results obtained from research on violence against women: an analysis of the work from reference center of the Social Assistance-CREAS, held in the city of Parnamirim/RN from September 2008 extending through the february of 2009. Having as goal to investigate and examine in a longitudinal cut, which specifically covers the period from 2006 to 2007, find out extent the actions taken by the Reference Center Specialized Social Assistance- CREAS, contributed to the change of women who were there, by checking if there was any change in their positions ahead of the violence and if they began to realize how social subjects, able to control their living conditions and interfere in the orientation of social dynamics Have a particular emphasis on the presence of work and schooling or lack of them is also a factor to be allied to the barriers and rules imposed on women in contemporary society. In this study it was found through a qualitative research guided by dialectical and implemented through the use of documentary research, observation, semi-structured interview and an extensive theoretical background on the subject in question that the woman victim of violence is in a complex and contradictory context where there is both the construction and deconstruction of rights, a view that there are strong influences of patriarchal culture and the consequences of social issues that specifically searched for the public, focuses on social, economic , political, social and cultural. In this sense, the National Policy to Combat Violence against Women, operated by CREASE Parnamirim, is also reflected in its early stages in the life of these women are to nurture a real chance for these victims of violence, to perceive themselves as social subjects can control their lives and interfere in their own destinies. We want this study to add more knowledge to help and most appropriate intervention in this reality, but without the intention of reaching exhaustion, but to subsidize future studies on the topic of women victims of violence

O Processo de revisão do benefício de prestação continuada-BPC: uma lógica de exclusão ou inclusão social

This research comprises a study about the social assessment performed by the Social Worker in the review process of the Benefit of Continued Installment. The Benefit of Continued Installment was implemented in 1996 and guarantees a minimum salary to the deficiency person and to an elder with sixty five years or more and that proves not to have ways to support neither himself/herself nor his/her own family. It is a demand to include in the BPC that the maximum income of a family does not exceed ¼ of minimum salary and that every two years this benefit to be revised to evaluate its continuity based in its original conditions. This study was carried out in the municipality of Natal/RN, with thirteen social workers, being the collection of data performed through interviews and social assessments of the users that count with the benefit. The results show that the users selected by the criterion of the income, present a profile of poverty and deprivations demonstrated through several situations survived in its daily life, indicative of vulnerability. It was demonstrated that the Social workers has relative autonomy in the evaluations along with the users and that it denotes the necessity of inclusion. However, by following the imposed criteria, it corroborates with the logic of exclusion. So, it is identified in the Municipality of Natal/RN, following the orientation given the politics of social work at national level, the implementation of revision of the BPC, for the social workers, from rigorous processes of selection and exclusions
