O Serviço Social e a exclusão/inclusão social dos portadores de HIV/AIDS :demandas e desafios nos hospitais públicos

This research presents the labors developed by the Social Service unto socially excluded HIV/Aids positives at public hospitals in Rio Grande do Norte (RN). It purposes to identify and to analyze the demands brought by the holder onto the Social Service professional as well as the challenges the latter face to minister to the former. It privileges, from the methodological viewpoint, the qualitative and quantitative analysis with the application of questionnaires, direct observation, semi-structured interviews and bibliographic references. Data were collected from 12 (twelve) social assistants who work at Giselda Trigueiro Hospital in Natal (7) and Rafael Fernandes Hospital in Mossoró (5). The central hypothesis that guided this study is that the social inclusion/exclusion process experienced by the HIV/Aids positive on society implies a demand for the Social Service that is inserted in the public health context (specially in HIV-referred public hospitals), whose agents, however, when attempting to answer those demands, meet obstacles due to both the precariousness of public health services and the social complexity that concerns the HIV/Aids epidemic. Results point out that, de facto, the HIV/Aids epidemic, because of the social exclusion/inclusion process to which the holder is subject results a demand for the social agents at hospitals. Demands rise principally from the patient s life condition, considering the increasing pauperization in the epidemic context. As to what it is concerned, social assistants, responding to the needs, come across concrete twofold challenges: the illness in itself, for all social, negative aspects that make part of quotidian life of holders; and the precarious state of the public health service in RN State, since that working conditions are unsatisfactory

A representação social de educação tecnológica de docentes da Rede Federal de Educação Profissional e Tecnológica: CEFETs do Rio Grande do Norte

The aim of this study was to investigate the social representation of technological education teachers at the Federal Technological Education Network. The survey was conducted from 2007 to 2010, and the respondents were 275 teachers, 135 of the Federal Center for Technological Education (CEFET in portuguese) in the state of Amazonas, in Manaus unit headquarters; 140 of the CEFET in the state of Rio Grande do Norte, a unit based in Natal. We adopt the concept of technological education as the top level of professional education, that is to say, the undergraduate programs of short duration called technological courses. The Federal Technological Education Network gathers hundreds of related institutions, coordinated and supervised by the Office of Vocational and Technological Education of the Ministry of Education. Although many of these institutions offer courses in technology education, no research addressing this subject from the perspective of Social Representations Theory (SRT) was found in the literature. We seek to unravel the social representation of technological education of the teachers by adopting the procedural approach of SRT. This is a qualitative approach, focusing on significant aspects of the representative activity and the formation mechanisms of the representation. Therefore, we search the socio-genesis of the representation in the articulations between discourses, social institutions and practices. We initiated the research through applying critical reading and an analytical perspective on the historical and regulatory documents of technological education in Brazil, from the early twentieth century to the present day. We adopt the Procedure for Multiple Classifications (PMC) from the Free Words Association Technique (FWAT) to access the elements of representational content. For the analysis of the data obtained with FWAT and selection of major words / phrases pertinent to the semantic field of education technology, we used Hamlet II software. For the data analysis of PMC and Free Classification (FC) we used the SPSS ® (Statistical Package for the Social Sciences) version 17.0 and used the method of multidimensional scaling - Multidimensional scaling - (MDS). The output from the central MDS takes the form of a set of scatterplots - "perceptual maps" - of which the points are the elements of the representational content. For the FC data analysis we used the Scalogram Multidimensional Analysis (SMA) - which makes use of the original data in its raw form and allows categorical data to be interpreted in the map as measures of (di)similarity. In order to help with the understanding of the settings of the perceptual maps of FC, we used the Content Analysis of the discourse fragments of the teachers interviewed. The results confirm our initial hypothesis regarding the presence of a single plot among the socio-cognitive study subjects, which is the basis for a social representation of technological education in line with the historic assumption of the dichotomy between mental and manual labor. In spite of the three merging representational elements of the representational content, the perceptual maps compiled from the MSA statistics corroborates the dichotomy, with the exception of the map relating to the subgroup of teachers belonging to the humanities

Colony defensive behavior by the social wasp Polybia (Trichothorax) sericea (Hymenoptera, Vespidae)

This work aimed at evaluating the aggressive response of Polybia sericea, incited by mechanical means, as well as collecting information on the biological and population parameters of this species in Caatinga environments. There were positive correlations (P < 0.05) between the number of aggressors and the number of eggs, larvae and adults present in the nests. These results showed that the magnitude of the defense response exhibited by P. sericea is proportional to the energetic investment carried out by the colony in making young forms. The positive significant correlation between the number of aggressors and the total number of adults of the colony corroborates the hypothesis that colonies with a large population of adults have greater potential to perform what is called defensive altruism.

Testing option pricing with the Edgeworth expansion

There is a well-developed framework, the Black-Scholes theory, for the pricing of contracts based on the future prices of certain assets, called options. This theory assumes that the probability distribution of the returns of the underlying asset is a Gaussian distribution. However, it is observed in the market that this hypothesis is flawed, leading to the introduction of a fudge factor, the so-called volatility smile. Therefore, it would be interesting to explore extensions of the Black-Scholes theory to non-Gaussian distributions. In this paper, we provide an explicit formula for the price of an option when the distributions of the returns of the underlying asset is parametrized by an Edgeworth expansion, which allows for the introduction of higher independent moments of the probability distribution, namely skewness and kurtosis. We test our formula with options in the Brazilian and American markets, showing that the volatility smile can be reduced. We also check whether our approach leads to more efficient hedging strategies of these instruments. (C) 2004 Elsevier B.V. All rights reserved.

Reinforcing and expanding the predictions of the disturbance vicariance hypothesis in Amazonian harlequin frogs: A molecular phylogenetic and climate envelope modelling approach

The disturbance vicariance hypothesis (DV) has been proposed to explain speciation in Amazonia, especially its edge regions, e. g. in eastern Guiana Shield harlequin frogs (Atelopus) which are suggested to have derived from a cool-adapted Andean ancestor. In concordance with DV predictions we studied that (i) these amphibians display a natural distribution gap in central Amazonia; (ii) east of this gap they constitute a monophyletic lineage which is nested within a pre-Andean/western clade; (iii) climate envelopes of Atelopus west and east of the distribution gap show some macroclimatic divergence due to a regional climate envelope shift; (iv) geographic distributions of climate envelopes of western and eastern Atelopus range into central Amazonia but with limited spatial overlap. We tested if presence and apparent absence data points of Atelopus were homogenously distributed with Ripley's K function. A molecular phylogeny (mitochondrial 16S rRNA gene) was reconstructed using Maximum Likelihood and Bayesian Inference to study if Guianan Atelopus constitute a clade nested within a larger genus phylogeny. We focused on climate envelope divergence and geographic distribution by computing climatic envelope models with MaxEnt based on macroscale bioclimatic parameters and testing them by using Schoener's index and modified Hellinger distance. We corroborated existing DV predictions and, for the first time, formulated new DV predictions aiming on species' climate envelope change. Our results suggest that cool-adapted Andean Atelopus ancestors had dispersed into the Amazon basin and further onto the eastern Guiana Shield where, under warm conditions, they were forced to change climate envelopes. © 2010 The Author(s).

The behavior and natural history of Chartergellus, a little-known genus of neotropical social wasps (Vespidae Polistinae Epiponini)

This study reviews published data on the behavior and natural history of Chartergellus and presents the first observations on social interactions in this genus of tropical swarm-founding wasps. Observations of Chartergellus golfitensis in Costa Rica and C. punctatior in Colombia showed that queens perform a post-oviposition egg-guarding vigil, and a bending display like that characteristic of epiponine social wasps that lack consistent morphological differences between workers and queens and have caste determination in the adult stage. Young, old, and queen (egg-laying) females of C. golfitensis showed small differences that indicate color changes with age, and structural differences that could be due to seasonal or colony-cycle changes in developmental conditions, but do not rule out the possibility of pre-adult caste determination, a phenomenon that needs to be carefully distinguished from pre-adult caste bias. Sexual dimorphism and the behavior of males at the nest in C. golfitensis is described, as well as the aggressive and avoidance behavior of females toward males. Nest structure in both species is as described previously for Chartergellus species, but some anomalies and their possible evolutionary significance are discussed. Cell initiation by an egg-laying queen, a behavior never seen by workers, and by a young female with slightly developed ovaries, may be vestiges of ancestral solitary reproductive traits where developed ovaries are associated with cell construction. © 2010 Dipartimento di Biologia Evoluzionistica dell'Università, Firenze, Italia.

Participação social e alternativas de desenvolvimento na Transamazônica: a ONG ASSEEFA o os PDSs de Anapu-PA

Esta dissertação discute a participação e alternativas de desenvolvimento na Transamazônica, a partir de estudo acerca da Organização Não-Governamental Associação Solidária e Econômica de Frutas da Amazônia (ASSEEFA) que é a encarregada pelos Projetos de Desenvolvimento Sustentável (PDSs), no município de Anapu, Transamazônica, Estado do Pará. Objetiva-se, verificar as imagens construídas sobre a ASSEEFA e os PDSs e, assim, apontar o grau de participação da sociedade civil de Anapu no processo de formulação e implementação de políticas alternativas de desenvolvimento para aquela região. Objetiva-se, ainda, explicitar em que campo se construíram as referências ao meio ambiente, presentes nas lutas dos movimentos sociais locais. Tomando como referência os conceitos apresentados por Ammann (1978) e Bordenave (1994), questionamos a existência ou não de participação social na criação da ASSEEFA e na implementação dos PDSs? Nesse sentido, as categorias participação social, sociedade civil, desenvolvimento, meio ambiente e Amazônia, com reflexos latentes nessa região, foram selecionadas como elementos centrais de análise, o que é realizado logo no primeiro capítulo. Com o intento de oferecer respostas à altura dos objetivos acima apontados, analisou-se, por meio de pesquisa bibliográfica e de campo, primeiro momento, a trajetória de constituição da ASSEEFA e dos PDSs. Observou-se, assim, que, nas parcerias, disputas e negociações da sociedade civil, existiam componentes relevantes que evidenciavam que aqueles movimentos possuem propostas voltadas para um tipo de desenvolvimento que valorize o meio ambiente e que, sobretudo, compromete-se com o resgate da cidadania. A análise dos pontos de vista das instituições governamentais como Instituto Nacional de Colonização e Reforma Agrária (INCRA) e Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA) e representantes da associação de madeireiros, serviu como referência para compreensão das diversas possibilidades, interesses e conflitos com que se apresentam as iniciativas da sociedade civil e a realização do desenvolvimento na Transamazônica. Tomamos como hipótese principal a formulação de que a participação social na ASSEEFA e nos PDSs de Anapu está ligada aos mais diversos interesses e que esta significa um rompimento com antigas práticas e visões sobre o desenvolvimento e a possibilidade desses agricultores de garantia de suas liberdades efetivas, como o direito a terra, ao trabalho, a educação e à saúde, em suma aos direitos fundamentais do ser humano.
