    OBJECTIVE: to analyze the relationship of masculinity, vulnerability and prevention of STD / HIV / AIDS among adolescent males of a land reform settlement in central Brazil. METHOD: a qualitative study using as precepts the strands of social representations with teenagers between 12 to 24 years. RESULTS: three categories emerged - Perception of vulnerability; Gender and vulnerability; and, Prevention and vulnerability to STD / HIV / AIDS. Adolescents felt invulnerable to sexually transmitted diseases anchored in the social representations in favor of the male hegemony. An ignorance about forms of prevention for STD / HIV / AIDS was demonstrated in their statements. It is believed that institutional projects such as the School Health Program and the Men's Health Care Program constitute essential tools to minimize factors of vulnerability in this population, since the school is recognized as a social facility that promotes socialization of experiences and contributes to the construction of the identity of the adolescent. CONCLUSION: the social representations of masculinity collaborate for the vulnerable behavior of the adolescents for the acquisition of sexually transmitted diseases. One hopes that this study can contribute to the production of knowledge and technical-scientific improvement of the professionals, especially the nurse, in order to discuss issues related to male sexuality of adolescents in the situation of the land reform settlement.OBJETIVO: analizar la relación de la masculinidad, la vulnerabilidad y la prevención de las ETS/VIH/SIDA entre los adolescentes varones de un asentamiento de reforma agraria en el centro de Brasil. MÉTODO: estudio cualitativo, utilizando como preceptos las fibras de las representaciones sociales de adolescentes entre 12 y 24 años. RESULTADOS: surgieron tres categorías - Percepción de la vulnerabilidad, el género y la vulnerabilidad y la prevención y la vulnerabilidad a las ETS/VIH/SIDA. Los adolescentes se sentían invulnerables a las enfermedades de transmisión sexual anclados en las representaciones sociales en favor de la hegemonía masculina. La ignorancia sobre las formas de prevención de ETS/VIH/SIDA, se demostró en sus declaraciones. Se cree que los proyectos institucionales como el Programa de Salud Escolar y el Programa de Salud de los Hombres constituyen herramientas esenciales para reducir al mínimo los factores de vulnerabilidad en esta población, ya que la escuela es reconocida como un centro social que promueve la socialización de experiencias y contribuye a la construcción de la identidad del adolescente. CONCLUSIÓN: las representaciones sociales de la masculinidad colaboran para el comportamiento de vulnerabilidad de los adolescentes para la adquisición de enfermedades de transmisión sexual. Se espera que este estudio pueda contribuir a la producción de conocimiento y a la mejora técnica-científica de los profesionales, especialmente la enfermera, con el fin de discutir temas relacionados con la sexualidad masculina de los adolescentes en la situación de los asentamientos de reforma agraria.OBJETIVO: analisar as relações de masculinidade, vulnerabilidade e prevenção às doenças sexualmente transmissíveis/HIV/Aids entre adolescentes do sexo masculino, de um assentamento da reforma agrária do Brasil Central. MÉTODO: estudo qualitativo, utilizando-se como preceitos as vertentes das representações sociais com adolescentes assentados de 12 a 24 anos. RESULTADOS: emergiram três categorias − percepção de vulnerabilidade, gênero e vulnerabilidade e prevenção e vulnerabilidade relacionadas às doenças sexualmente transmissíveis/HIV/Aids. Os adolescentes sentem-se invulneráveis às doenças de transmissão sexual ancorados nas representações sociais favoráveis à hegemonia masculina. Demonstraram, em seus discursos, um desconhecimento sobre as formas de prevenção às doenças sexualmente transmissíveis/HIV/Aids. Acredita-se que projetos institucionais como o Programa Saúde na Escola e o Programa de Atenção à Saúde do Homem constituem ferramentas imprescindíveis para minimizar fatores de vulnerabilidades nessa população, uma vez que a escola, reconhecida como equipamento social, promove a socialização de experiências e contribui para a construção da identidade do adolescente. CONCLUSÃO: Conclusão: as representações sociais da masculinidade colaboram para o comportamento vulnerável dos adolescentes na aquisição de doenças de transmissão sexual. Almeja-se que este estudo possa contribuir para a produção de conhecimentos e aperfeiçoamento técnico-científico dos profissionais, especialmente o enfermeiro, com vistas a discutir as questões relativas à sexualidade masculina dos adolescentes em situação de assentamento da reforma agrária

RESULTADOS: a maioria era de mulheres adultas jovens, com baixa escolaridade e conhecimento insuficiente sobre formas de transmissão do vírus da imunodeficiência humana. Mais de um terço das mulheres não soube informar os sinais/sintomas das doenças sexualmente transmissíveis. A prevalência de corrimento vaginal e ferida/úlcera foi de 49,0 e 8,6%, respectivamente, sendo que 41,7% dessas não procuraram tratamento. CONCLUSÃO: os resultados evidenciam a necessidade de políticas públicas de saúde voltadas para o controle e prevenção das doenças sexualmente transmissíveis nessa população, especialmente, em mulheres que comercializam sexo em importante rota de prostituição e turismo sexual do Brasil Central.OBJECTIVE: to investigate knowledge on sexually transmitted diseases (STDs), STD-related risk behaviors, and signs/symptoms of STDs among female sex workers (FSWs). METHODS: a cross-sectional study was conducted with a probabilistic sample comprising 395 women recruited using a respondent-driven sampling method between 2009 and 2010. The data were collected during face-to-face interviews. RESULTS: most of the participants were young adults, had a low educational level, and had poor knowledge on the transmission paths of the human immunodeficiency virus (HIV). Over one-third of the participants were not able to describe the signs/symptoms of STDs. The prevalence rates of vaginal discharge and wounds/ulcers were 49.0% and 8.6%, respectively, but 41.7% of the women had not sought treatment. CONCLUSION: the results indicate the need for public health policies focusing on the control and prevention of STDs in this population, especially for the FSWs who are active in an important prostitution and sex tourism route in central Brazil

    Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

    Search for stop and higgsino production using diphoton Higgs boson decays

    Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

    Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

    Get PDF
    Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

    Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

    The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe
