A organização sindical dos assistentes sociais no Brasil: dilemas e desafios contemporâneos

This paper discusses the dilemmas and challenges of the union of social workers in contemporary Brazil. The study is supported by the theme in a literature search, especially productions that deal with the trade union movement of workers in the brazilian reality, as well as on field research, which consisted of interviews with national trade union leaders of the CUT and CONLUTA as also representatives of national organizations representing the professional category of social workers, notably CFESS, ABEPSS ENESSO and a labor union and the national category, FENAS. The analysis of the object is oriented in the perspective of totality, considering its founding and contradictory aspects of the current socio-historical dynamics. The inflections occurred in the razilian Labor Movement in the early 1990s, during which the offensive of capital, characterized by the fusion of flexible accumulation and the dictates of neoliberal policy is established in the country, caused a profound shock in life and organization of the class working. The major repercussions of this process are evident today in the form of defensive organization of trade union struggles, notably fragile and fragmented. In the case of the category of social workers is symptomatic of the political backlash, experienced the process of reopening their unions and the creation of FENAS. This definition, part of the analysis that considers more strategic perspective of class organization, corporate antiunionism of the mass of the 1980s, built, largely, by category and expressed by the extinction of their union and unification to the broader struggles of workers with transition to unionization by industry. Given this reality, we analyze the performance of the political perspectives of the brazilian labor movement, from the characterization of organizational arrangements for trade union struggles and situate this process, the motion to reopen union of social workers, from the emergence of FENAS. Therefore, we aimed to identify the particular and the ideological and political perspectives that make up the dilemma of the trade union movement from this reopening, as corresponds to a political trend, largely, overcome within the brazilian social work

Garantia literária: elementos para uma revisão crítica após um século

This study contributes to a critical synthesis of the principle of literary warrant, initially formulated by Hulme in 1911. Hulme proposed that the terms of a classification system should be derived from the literature to be classified, rather than based on purely theoretical considerations. Founding literary warrant on literature which is actually documented rather than on scientific or philosophical classifications or on the supposed authority of the first classificationists implied a clear departure from the conceptions of Harris and Dewey, who had used the classifications of Bacon and Leibniz as models. The validity of this principle over the past century is studied by means of diverse documental data (entries in dictionaries, retrieval by Google, etc.), as it is recognized as a main methodological element for classification standards and systems. This study also discusses the situation with respect to the top-down or bottom-up methodologies of system design. Three traditional applications of literary warrant are described as well as three new applications are suggested, in light of its methodological potential. It is possible to conclude that this principle will find increasing applications in other contexts, within and beyond Information Science.

O ecoturismo sob a égide da sociedade do consumo: um estudo das Unidades de Conservação de uso sustentável do RN

Ecotourism, in face to environmental demands and discussions, has achieved prominence in the tourism market and wide global development, occasioning a concern about the need for a scientific deepening through a critical approach of the dynamics of consumption and conservation that permeate this practice. This study addresses the ecotourism under aegis of consumer society, in which is perceived that it constitutes a contester practice of society in which it is embedded, nevertheless has been subjected to the logic of capital through commodification of nature. In order to comprehend the reality presented, this study had as geographical cutting two Conservation Units of Sustainable Use in Rio Grande do Norte state: the Jenipabu Environmental Protection Area (APAJ) and Ponta do Tubarão State Sustainable Development Reserve (RDSEPT). The research sought to investigate the relationship between conservation and consumption and their influences on ecotourism held in the Conservation Units (UCs) of sustainable use selected for this study. To this aim it was made a critical reflection about the relationship conservation versus consumption constant in the practice of ecotourism in UCs in the context of current society, analyzing the historical process of formation of UCs of sustainable use in RN state under the light of the contradictory pair conservation-consumption, as well as looking to apprehend the perception of ecotourism of the actors involved with this practice. It was adopted a qualitative approach under a critical perspective based on bibliographical and documentary research and realization of semi-structured interviews with three groups of actors, namely managers/technician, community and ectourists involved with ecotourism in the selected UCs. The analysis was made using two basic units of analysis (consumption and maintenance) and twelve categories. For definition of units of analysis and categories were taken as reference the authors Santos (1987; 1988; 1994; 2001; 2006), Guerreiro Ramos (1989) and A. B. Rodrigues (1996; 2003), which perform critical to society of consumption and describe the key characteristics of the technical-scientific-informational predominant means, and Diegues (1998; 2000), A. B. Rodrigues (2001), Pires (2002) and Neiman and Rabinovici (2010), which discusse historic and scientifically about the emphasis on conservation present in origins and discourse of ecotourism, describing also its founding characteristics. The main results show that the marketing use of the prefix eco has acted as a new dress for what in reality is in fact ancient, ie, the conservation is used as a justification for another new type of consumption. The results also show that despite the coexistence of commercial and symbolic intentions in both UCs, one can observe the predominance consumer society characteristics in the process of creation and the production activities of APAJ, while in RDSEPT we note the predominance of the conservationist characteristics proclaimed by ecotourism. It can be inferred therefore that tourism held in the APAJ can not be called ecotourism, while the practice found in RDSEPT show an alignment with the guidelines of ecotourism

Necrophagy by the social wasp Agelaia pallipes (Hymenoptera : Vespidae, Epiponini): Possible forensic implications

The occurrence of 62 specimens of Agelaia pallipes caught in carrion traps using three types of baits (fish, cow liver and poultry viscera) in three different types of environments (rural, urban and forest area) in seven municipalities in Southeastern Brazil is reported here. This specific necrophagic behavior is discussed, since investigations concerning carrion wasps are scant in literature.

On the morphology of the worker immatures of the leafcutter ant Atta sexdens linnaeus (Hymenoptera: Formicidae)

Leafcutter ants of the genus Atta Fabricius are serious agricultural pests. Morphological studies of immature stages within this group are few, and the data provided for species of considerable importance are usually incomplete. In this study, the immatures of Atta sexdens Linnaeus are described and compared using light and scanning electron microscopy. Only specimens from founding stage colonies (i.e., lacking adult workers) were used. The existence of four larval instars was estimated by a frequency plot of maximum head widths, and the larvae of different instars differed from each other mainly by their bodily dimensions. Worker larvae belonged to two distinct morphological castes: (1) gardeners and nurses and (2) within-nest generalists. The worker larvae described in this study differed from a previous description of the same species by the following traits: the existence of a genal lobe, the number of clypeal hairs, the presence of two hairs on the ninth abdominal somite, the presence of hairs on the anterior surface of the labrum, and the shape of the maxillary palpus. This study provides a comparative analysis of immature stages of A. sexdens that may be relevant to future morphological and biological studies of the Attini. Microsc. Res. Tech. 75:10591065, 2012.

Morphology of Richards' Gland in the Wasp Metapolybia docilis

Richards gland in the epiponine wasp Metapolybia docilis occurs at the anterior side of the 5(th) abdominal sternite, and is formed by approx. 360 secretory cells. The cells discharge their secretory products through accompanying duct cells into a reservoir that is formed by the invaginated intersegmental membrane between the 4(th) and 5(th) sternites. The ultrastructural characteristics of the secretory cells are indicative for the production of a non-proteinaceous secretion, which is in line with the trail substance that is used by these wasps during their swarm-founding.

PATTERNS OF COLONIZATION AND INCIPIENT NEST SURVIVAL IN ACROMYRMEX-NIGER AND ACROMYRMEX-BALZANI (HYMENOPTERA, FORMICIDAE)

Patterns of colonization by queens and incipient nest survival of the leaf-cutting ants Acromyrmex niger and Acromyrmex balzani were studied by means of belt transects and individually marked incipient nests. No relation was found between colony density and the number of colonization attempts. Both species are not claustral, and high rates of queen mortality were attributed to conspecific executions and predation. of other discernable mortality factors, failure of fungal garden establishment was the most important. Only 34 of 296 A. balzani and 13 of 154 A. niger marked colonies were alive at the end of one year. These figures are higher than those reported for species of Atta. These results are contrasted with those of claustral-founding Atta species. Small colonies are occasionally raided by larger colonies which robbed brood.

COMPARATIVE COLONY PRODUCTIVITY OF POLISTES-SIMILLIMUS AND POLISTES-VERSICOLOR (HYMENOPTERA, VESPIDAE) AND THE EVOLUTION OF PARAGYNY IN THE POLISTINAE

Over a 3-year period, all colony foundations of the social wasps Polistes versicolor and Polistes simillimus were registered, and the fate and growth of all colonies were followed. P. simillimus exhibited a greater number of colony-founding attempts, while P. versicolor had a larger number of adult colonies. P. simillimus had greater cell numbers and number of adults produced per colony. P. simillimus reutilized only a small percentage of brood cells for adult production for up to 2 generations, while P. versicolor reutilized a large percentage of brood cells for up to 3 generations. Consequently, cell production was higher in P. simillimus. Because of a high rate of adult production and extensive cell production, we suggest that P. simillimus may demonstrate paragynous social organization, and may demonstrate an intermediate form between polygynous and monogynous Vespidae. Paragynous associations may lead to lower predation pressures and a relative independence of adult production on time.

Prevenção de hemoglobinopatias a partir do estudo em gestantes

The Brazilian population, presents genes for abnormal hemoglobins with variable frequencies, which are influenced by the founding racial groups. Thus, the detection of carriers of the genetic alterations is important for public health, since they represent sources of new beterozygotes and possible homozygotes. The control of the hemoglobin pathologies has been possible by means of genetic counseling and early diagnosis. The clinical follow-up of the homozygotes and the orientation of the beterozygotes and especially the couples at risk represent a more effective mode of acting to avoid the birth of children who are carriers of a genetic disease, that is frequently lethal. For these reasons this work had as its objectives: to evaluate the importance of testing in pregnant women for the detection of hemoglobin pathologies with the purpose of investigating the prevalence, attaining prevention, a familial study and awareness; for the positive cases such as couples at risk, orient as to appropriate medical attendance; and to evaluate the response to the program. Of the total of 696 pregnant women analysed, 10.7% revealed hemoglobin pathologies with the following rates: alpha Thalassemia 6.75%; Hb AS 2.01%; beta minor Thalassemia 1.29%; Hb AC 0.28%; Hb AJ 0.14%; Hb AS/Alpha Thalassemia 0.14% and P.H.H.F. 0.14%. The high rates of hemoglobin pathologies encountered in the population of pregnant women studied shows the necessity of the implantation of tests for these abnormalities in the pre-natal routine, since in this period the mothers are more apt to be preoccupied with their own health and that of their babies and, however earlier diagnosed the alterations in the hemoglobins, better and more adequate will be the orientations given the couple.
