Homo e Heterossexuais: o papel das memórias de vergonha, das memórias precoces de calor e segurança, e qualidade de vinculação ao pai, à mãe e ao par amoroso

As experiências precoces de vergonha, na infância e adolescência, cujas memórias assumem características traumáticas, e de centralidade para a identidade, estão associadas a maior propensão para a vergonha e psicopatologia na adultez. O presente estudo visou clarificar o impacto das características traumáticas e da centralidade, das memórias de vergonha, e das memórias precoces de calor e segurança, na qualidade de vinculação aos pais e ao par amoroso, apreciando a orientação sexual. Nesse sentido, 123 sujeitos, homossexuais masculinos (N = 53) e heterossexuais masculinos e femininos (N = 70), completaram a bateria de questionários de autorresposta, para avaliar as caraterísticas traumáticas e a centralidade das memórias de vergonha, as memórias precoces de calor e segurança, a qualidade de vinculação ao pai, à mãe e ao par amoroso, recolhidos a partir de amostra de conveniência não aleatória da população geral. Os resultados mostram que os homossexuais, comparativamente com os heterossexuais, apresentam níveis mais elevados de caraterísticas traumáticas e de centralidade para a identidade, das memórias de vergonha, a par de níveis inferiores de memórias precoces positivas. As caraterísticas traumáticas e de centralidade, das memórias de vergonha, surgem associadas, com intensidade tendencialmente superior nos homossexuais, à restrição da aquisição de autonomia, conferida pelo pai, à sua desvalorização e à ansiedade de separação materna. O vínculo inseguro, aos progenitores, perpetua-se à adultez e ao par amoroso. Relativamente aos heterossexuais, apurámos que o laço emocional e a ansiedade de separação e dependência, paterna e materna, surgem associados a maior confiança e menor evitamento, respetivamente, ao par amoroso. Paralelamente, a ansiedade de separação e dependência materna surge, ainda, associada a maior dependência daquela figura. Este estudo conclui que as experiências precoces de vergonha, na infância e adolescência, podem funcionar como memórias com caraterísticas traumáticas e autobiográficas, constituir marcos de referência centrais no que concerne à identidade e história de vida, sobretudo em homossexuais, com atribuição de significado a outras experiências de vida, nomeadamente no que respeita à vinculação ao par romântico. / Early experiences of shame, in childhood and adolescence, whose memories assume traumatic characteristics, and centrality to identity, are associated with greater propensity to shame and psychopathology in adulthood. The present study aimed to clarify the impact of traumatic features and centrality to identity of shame memories, and of early memories of warmth and safety, on quality of attachment to parents and the loving couple`s bond, considering sexual orientation. Accordingly, 123 subjects, male homosexuals (N = 53) and male and female (N = 70) heterosexuals, completed the battery of self-report questionnaires, to assess trauma characteristics and centrality of shame memories, early memories of warmth and safeness, quality of attachment to the father, mother and loving couple, collected from a non-random convenience sample from general population. The results point that homosexual men, compared with heterosexuals, show higher levels of traumatic characteristics and centrality to identity of shame memories, along with lower levels of early positive memories. Traumatic characteristics and centrality of shame memories arise associated, tendentiously with higher intensity in homosexuals, to restriction of autonomy`s acquisition, conferred by the father, his devaluation and maternal separation anxiety. The unsecured bond, to parents, perpetuates into adulthood and loving couple. Regarding heterosexuals, we found that emotional bond and separation anxiety and dependency, paternal and maternal, arise associated with greater confidence, and less avoidance, respectively, to the loving couple. Further, separation anxiety and mother`s dependency also appears associated with greater dependency to that figure. This study concludes that early experiences of shame, in childhood and adolescence, might function as memories with traumatic and autobiographical characteristics, produce landmarks of central reference regarding identity and life`s history, particularly in homosexual, with attribution of meaning to other life experiences, particularly in the linking to the romantic couple.

Cuidados Paliativos em Portugal na Perspectiva de Assistentes Sociais

O contexto demográfico e epidemiológico hodierno traz à luz a fulcral relevância dos cuidados paliativos de qualidade acessíveis para todos. Pela importância que o serviço social assume na defesa da garantia dos direitos humanos, com uma ação direta nestes cuidados, o presente estudo pretendeu analisar os cuidados paliativos na perspectiva de assistentes sociais, tendo em conta o atual contexto das políticas sociais e de saúde. Optou-se por uma investigação quanti e qualitativa, através de um inquérito por questionário dirigido a todas as unidades/equipas de cuidados paliativos identificadas no território nacional (Portugal Continental e Regiões Autónomas), com assistentes sociais. A amostra foi constituida por 17 profissionais de serviço social, na sua maioria mulheres (94,1%), com idades entre os 25 e os 57 anos, a exercer a profissão há 5,5 anos, em média, na área dos cuidados paliativos. Os resultados do estudo mostram-nos que os assistentes sociais estão inseridos em 86,36% das unidades/equipas, sendo estas maioritamente de natureza pública. Os profissionais mais frequentes na constituição das equipas são o médico, enfermeiro, assistente social e psicólogo. Todos ou quase todos têm formação específica na área, tendo a maioria apoio para formação continuada. As condições de trabalho atuais foram alvo de uma avaliação desfavorável por parte da amostra. Estes profissionais perspectivam o acesso a estes cuidados como sendo pouco equitativos, apontam a falta quer de estruturas que cubram geograficamente todo o país, quer de recursos humanos adequados, não esquecendo a ausência de regulamentação da atividade laboral dos profissionais nos cuidados paliativos. É exigido ao assistente social uma intervenção baseada no cumprimento de objetivos que apresentem resultados rápidos, o que tem vindo a dificultar uma intervenção eficaz desde a admissão até ao encaminhamento do doente para continuidade de cuidados. A presente investigação oferece um contributo para a produção de conhecimento capaz de evidenciar as transformações que têm vindo a ocorrer na prática dos profissionais permitindo contribuir para a reflexão sobre os contextos e processos de intervenção, assim como sobre a promoção do direito aos cuidados paliativos de qualidade em Portugal. / The current demographic and epidemiological context highlights the crucial importance of quality palliative care accessible for all. The importance that social work assumes in the defense of human rights guarantees, with a direct action on these care, this study aims to analyze the palliative care from the perspective of social workers, taking into account the current context of social and health policies. We chosed a quantitative and qualitative research through a questionnaire addressed to the universe of the palliative care institutions identified in the national territory (Portugal’s mainland and the Autonomous Regions), with social workers. The sample has 17 social work professionals, mostly women (94.1%), aged between 25 and 57 years. They work as a social worker for 5.5 years on average in the area of care palliative. The results of the study show us that social workers are included in 86.36% of the units / teams, wich are mostly public services. The most frequent professionals in the teams are the doctor, nurse, social worker and psychologist. All or almost all have specific training in the area, and the majority has institutional support for continuing training. Current conditions of work have received an unfavorable evaluation by the participants. The inquired considered access to palliative care as being inequitable, or point to a lack of structures that geographically cover the whole country, whether adequate human resources, not to mention the lack of regulation of the activity of professionals working in palliative care. An intervention based on the achievement of goals that have quick results, which have been a difficulty for an effective intervention from the admission to the referral of the patient for continuity of care is required of the social worker. This research offers a contribution to knowledge production, able to highlight the changes that have taken place in professional practice, allowing to contribute to the reflection about the contexts and processes of intervention as well as on the promotion of the right to quality palliative care of in Portugal.

Asymmetric polygons with maximum area

We say that a polygon inscribed in the circle is asymmetric if it contains no two antipodal points being the endpoints of a diameter. Given n diameters of a circle and a positive integer k < n, this paper addresses the problem of computing a maximum area asymmetric k-gon having as vertices k < n endpoints of the given diameters. The study of this type of polygons is motivated by ethnomusiciological applications.

iNOS-producing inflammatory dendritic cells constitute the major infected cell type during the chronic Leishmania major infection phase of C57BL/6 resistant mice.

Leishmania major parasites reside and multiply in late endosomal compartments of host phagocytic cells. Immune control of Leishmania growth absolutely requires expression of inducible Nitric Oxide Synthase (iNOS/NOS2) and subsequent production of NO. Here, we show that CD11b+ CD11c+ Ly-6C+ MHC-II+ cells are the main iNOS-producing cells in the footpad lesion and in the draining lymph node of Leishmania major-infected C57BL/6 mice. These cells are phenotypically similar to iNOS-producing inflammatory DC (iNOS-DC) observed in the mouse models of Listeria monocytogenes and Brucella melitensis infection. The use of DsRed-expressing parasites demonstrated that these iNOS-producing cells are the major infected population in the lesions and the draining lymph nodes. Analysis of various genetically deficient mouse strains revealed the requirement of CCR2 expression for the recruitment of iNOS-DC in the draining lymph nodes, whereas their activation is strongly dependent on CD40, IL-12, IFN-gamma and MyD88 molecules with a partial contribution of TNF-alpha and TLR9. In contrast, STAT-6 deficiency enhanced iNOS-DC recruitment and activation in susceptible BALB/c mice, demonstrating a key role for IL-4 and IL-13 as negative regulators. Taken together, our results suggest that iNOS-DC represent a major class of Th1-regulated effector cell population and constitute the most frequent infected cell type during chronic Leishmania major infection phase of C57BL/6 resistant mice.

Party Members’ Preferences and the Changing Nature of Party Representation: Does Representation Change when Parties become Mini-Republics?

Giovanni Sartori famously wrote that political parties do not need to be mini-republics, yet today parties in many parliamentary democracies are moving in this direction by giving their members direct votes over important decisions, including selecting party leaders and settling policy issues. This paper explores some of the implications of these changes. It asks whether the addition of membership rights affects the types of members who are attracted: do we find a bigger gap between the preferences of party members and of party voters in parties that are more plebiscitary, as literature on members' motivations might lead us to expect? The paper examines this question both cross-sectionally and longitudinally using opinion data from the European Social Survey and newly-available party organizational data from the Political Party Database project.

Measuring, Modeling, and Forecasting Volatility and Correlations from High-Frequency Data

This dissertation contains four essays that all share a common purpose: developing new methodologies to exploit the potential of high-frequency data for the measurement, modeling and forecasting of financial assets volatility and correlations. The first two chapters provide useful tools for univariate applications while the last two chapters develop multivariate methodologies. In chapter 1, we introduce a new class of univariate volatility models named FloGARCH models. FloGARCH models provide a parsimonious joint model for low frequency returns and realized measures, and are sufficiently flexible to capture long memory as well as asymmetries related to leverage effects. We analyze the performances of the models in a realistic numerical study and on the basis of a data set composed of 65 equities. Using more than 10 years of high-frequency transactions, we document significant statistical gains related to the FloGARCH models in terms of in-sample fit, out-of-sample fit and forecasting accuracy compared to classical and Realized GARCH models. In chapter 2, using 12 years of high-frequency transactions for 55 U.S. stocks, we argue that combining low-frequency exogenous economic indicators with high-frequency financial data improves the ability of conditionally heteroskedastic models to forecast the volatility of returns, their full multi-step ahead conditional distribution and the multi-period Value-at-Risk. Using a refined version of the Realized LGARCH model allowing for time-varying intercept and implemented with realized kernels, we document that nominal corporate profits and term spreads have strong long-run predictive ability and generate accurate risk measures forecasts over long-horizon. The results are based on several loss functions and tests, including the Model Confidence Set. Chapter 3 is a joint work with David Veredas. We study the class of disentangled realized estimators for the integrated covariance matrix of Brownian semimartingales with finite activity jumps. These estimators separate correlations and volatilities. We analyze different combinations of quantile- and median-based realized volatilities, and four estimators of realized correlations with three synchronization schemes. Their finite sample properties are studied under four data generating processes, in presence, or not, of microstructure noise, and under synchronous and asynchronous trading. The main finding is that the pre-averaged version of disentangled estimators based on Gaussian ranks (for the correlations) and median deviations (for the volatilities) provide a precise, computationally efficient, and easy alternative to measure integrated covariances on the basis of noisy and asynchronous prices. Along these lines, a minimum variance portfolio application shows the superiority of this disentangled realized estimator in terms of numerous performance metrics. Chapter 4 is co-authored with Niels S. Hansen, Asger Lunde and Kasper V. Olesen, all affiliated with CREATES at Aarhus University. We propose to use the Realized Beta GARCH model to exploit the potential of high-frequency data in commodity markets. The model produces high quality forecasts of pairwise correlations between commodities which can be used to construct a composite covariance matrix. We evaluate the quality of this matrix in a portfolio context and compare it to models used in the industry. We demonstrate significant economic gains in a realistic setting including short selling constraints and transaction costs.

Auditoría financiera a la Empresa Sagitta Cia. Ltda. de 1 de enero al 31 de diciembre del 2010

Una de las principales características de las sociedades en la actualidad es los caudales de información que poseen, pero para que esa información sea correcta, es necesario que esté avalada por ciertas garantías que hoy en día es la Auditoria. El objetivo al realizar la Auditoria Financiera es suministrar información útil y comprensible. Una correcta aplicación de las Normas Internacionales de Auditoría y Aseguramiento, con el objeto de emitir una opinión crítica y fundamentada de la realidad de los Estados Financieros de las misma, así como evaluar y diagnosticar el cumplimiento de sus objetivos y metas para formular el dictamen, respecto de la razonabilidad con que se presentan los resultados de la situación financiera, para determinar el cumplimiento de las disposiciones legales, mejorar los procedimientos relativos a la gestión financiera y al control interno. Utilizamos como técnicas de Auditoría: entrevistas, cuestionarios de control interno y papeles de trabajo. Como resultado final de la Auditoria Financiera llevada a cabo en la Empresa “Sagitta Cía. Ltda.” es la emisión de un informe, en el que el auditor da a conocer su opinión sobre la situación financiera de la empresa, este proceso solo es posible llevarlo a cabo a través de un elemento llamado evidencia de auditoria. La auditoría en los negocios es muy importante, por cuanto las empresas, sin la práctica de una auditoria no tienen plena seguridad de que los datos económicos registrados realmente son verdaderos y confiables.

Influence of the perception of discrimination on women's work motivation

Nowadays, despite anti-discrimination policies, women suffer frequently from a lack of consideration from their male colleagues, altering their well-being and motivation to work. More precisely, perceived personal or groupal discrimination, could have a distinct influence on work motivation. Previous studies showed that the impact on women varies in function of the type of perceived discrimination (Bourguignon et al. 2006). Based on the self-categorization and the social identity theory, work motivation is differently structured as if employees categorized themselves as individuals or as part of a group. As a result, a different impact from personal and group discrimination on work motivation is expected. Moreover, it has been proved that typical men behavior is heavily associated with competence compared to women behavior (Marchand, Saint-Charles & Corbeil, 2007). Therefore, it is hypothesized that women with more masculine traits will suffer from less perceived discrimination, and work motivation. An online survey was created in order to collect data over work motivation, perceived personal and group discrimination. The respondents were also questioned on typical men and women behavior to determine their gender-conformity. To test our hypotheses, data were collected from 57 women stemming from the labour force, aged from 21 to 63 years old. Results indicate that perceived personal discrimination was negatively related to work motivation and that perceived group discrimination was negatively correlated with masculine behavior. Thereby, our study enhances the importance of work environment, and especially discrimination, on work motivation. This research also corroborates the self-categorization and the social identity theory framework to study these issues.
