Modelling the line variations from the wind-wind shock emissions of WR 30a

The study of Wolf-Rayet stars plays an important role in evolutionary theories of massive stars. Among these objects, similar to 20 per cent are known to be in binary systems and can therefore be used for the mass determination of these stars. Most of these systems are not spatially resolved and spectral lines can be used to constrain the orbital parameters. However, part of the emission may originate in the interaction zone between the stellar winds, modifying the line profiles and thus challenging us to use different models to interpret them. In this work, we analysed the He II lambda 4686 angstrom + C IV lambda 4658 angstrom blended lines of WR 30a (WO4+O5) assuming that part of the emission originate in the wind-wind interaction zone. In fact, this line presents a quiescent base profile, attributed to the WO wind, and a superposed excess, which varies with the orbital phase along the 4.6-d period. Under these assumptions, we were able to fit the excess spectral line profile and central velocity for all phases, except for the longest wavelengths, where a spectral line with constant velocity seems to be present. The fit parameters provide the eccentricity and inclination of the binary orbit, from which it is possible to constrain the stellar masses.

Sexual System, Sex Ratio, and Group Living in the Shrimp Thor amboinensis (De Man): Relevance to Resource-Monopolization and Sex-Allocation Theories

The sexual system of the symbiotic shrimp Thor amboinensis is described, along with observations on sex ratio and host-use pattern of different populations. We used a comprehensive approach to elucidate the previously unknown sexual system of this shrimp. Dissections, scanning electron microscopy, size-frequency distribution analysis, and laboratory observations demonstrated that T amboinensis is a protandric hermaphrodite: shrimp first mature as males and change into females later in life. Thor amboinensis inhabited the large and structurally heterogeneous sea anemone Stichoclactyla helianthus in large groups (up to 11 individuals) more frequently than expected by chance alone. Groups exhibited no particularly complex social structure and showed male-biased sex ratios more frequently than expected by chance alone. The adult sex ratio was male-biased in the four separate populations studied, one of them being thousands of kilometers apart from the others. This study supports predictions central to theories of resource monopolization and sex allocation. Dissections demonstrated that unusually large males were parasitized by an undescribed species of isopod (family Entoniscidae). Infestation rates were similarly low in both sexes (approximate to 11%-12%). The available information suggests that T. amboinensis uses pure search promiscuity as a mating system. This hypothesis needs to be formally tested with mating behavior observations and field measurements on the movement pattern of both sexes of the species. Further detailed studies on the lifestyle and sexual system of all the species within this genus and the development of a molecular phylogeny are necessary to elucidate the evolutionary history of gender expression in the genus Thor.

Renormalization of the S parameter in holographic models of electroweak symmetry breaking

We show that the S parameter is not finite in theories of electroweak symmetry breaking in a slice of anti-de Sitter five-dimensional space, with the light fermions localized in the ultraviolet. We compute the one-loop contributions to S from the Higgs sector and show that they are logarithmically dependent on the cutoff of the theory. We discuss the renormalization of S, as well as the implications for bounds from electroweak precision measurements on these models. We argue that, although in principle the choice of renormalization condition could eliminate the S parameter constraint, a more consistent condition would still result in a large and positive S. On the other hand, we show that the dependence on the Higgs mass in S can be entirely eliminated by the renormalization procedure, making it impossible in these theories to extract a Higgs mass bound from electroweak precision constraints.

An Evaluation of”Middle Ages Dead or Live?”The first interactive exhibition at the National Museum of History

This is a study conducted at, and for, the National Museum of History in Stockholm. The aim of the study was to confirm or disconfirm the hypothesis that visitors in a traditional museum environment might not take part in interactivity in an interactive exhibition. And if they do the visitors might skip the texts and objects on display. To answer this and other questions a multiple method was used. Both non participant observations and exit interviews were conducted. After a description of the interactive exhibits, theory of knowledge and learning is presented before the gathered data is presented. All together 443 visitors were observed. In the observations the visitors were timed on how much time they spent in the room, the time spent on the interactivity, texts and objects. In the 40 interviews information about visitors’ participation in the interactivity was gathered. What interactivity the visitor found easiest, hardest, funniest and most boring.The result did not confirm the hypothesis. All kinds of visitors, children and adults, participated in the interactivities. The visitors took part in the texts and objects and the interactive exhibits.

Thick viewing : empirical examples of condensed moments of narrative impact in fiction film developing theoretical concepts for intensified engagements

Abstract  In a case study about viewing habits in a Swedish audience I sampled 309 questionnaires; interviews with five focus group were conducted together with ten in-depth individual interviews discussing altogether fifteen favorite films exploring specific scenes of idiosyncratic relevance.  The outcome supports claims about viewers as active and playful (cf. Höijer 1998, Frampton 2006, Hoover 2006, Plantinga 2009). In line with mediatization theory I also argue that spiritual meaning making takes place through mediated experiences and I support theories about fiction films as important sources for moral and spiritual reflection (Partridge 2004, Zillman 2005, Lynch 2007, Plantinga 2009). What Hjarvard calls the soft side of mediatization processes (2008) is illustrated showing adults experiencing enchantment through favorite films (Jerslev 2006, Partridge 2008, Klinger 2008, Oliver & Hartmann 2010).  Vernacular meaning making embedded in everyday life and spectators dealing with fiction narratives such as Gladiator, Amelie from Montmartre or Avatar highlights the need for a more nuanced understanding of elevated cinematic experiences. The reported impact of specific movies is analyzed through theories where cognition and affect are central aspects of spectators’ engagements with a film (Tan 1996, Caroll 1999, Grodal 2009). Crucially important are theories of meaning-making where viewers’ detailed interpretation of specific scenes are embedded in high-level meaning-making where world view issues and spectators’ moral frameworks are activated (Zillman 2005, Andersson & Andersson 2005, Frampton 2006, Lynch 2007, Avila 2007, Axelson 2008, Plantinga 2009).  Also results from a growing body of empirical oriented research in film studies are relevant with an interest in what happens with the flesh and blood spectator exposed to filmic narratives (Jerslev 2006, Klinger 2008, Barker 2009, Suckfüll 2010, Oliver & Hartmann 2010). Analyzing the qualitative results of my case study, I want to challenge the claim that the viewer has to suspend higher order reflective cognitive structures in order to experience suture (Butler & Palesh 2004). What I find in my empirical examples is responses related to spectators’ highest levels of mental activity, all anchored in the sensual-emotional apparatus (Grodal 2009). My outcome is in line with a growing number of empirical case studies which support conclusions that both thinking and behavior are affected by film watching (Marsh 2007, Sückfull 2010, Oliver & Hartmann 2010, Axelson forthcoming). The presentation contributes to a development of concepts which combines aesthetic, affective and cognitive components in an investigation of spectator’s moves from emotional evaluation of intra-text narration to extra-textual assessments, testing the narrative for larger significance in idiosyncratic ways (Bordwell & Thompson 1997, Marsh 2007, Johnston 2007, Bruun Vaage 2009, Axelson 2011). There are a several profitable concepts suggested to embrace the complex interplay between affects, cognition and emotions when individuals respond to fictional narratives. Robert K. Johnston label it “deepening gaze” (2007: 307) and “transformative viewing” (2007: 305). Philosopher Mitch Avila proposes “high cognition” (2007: 228) and Casper Thybjerg ”higher meaning” (2008: 60). Torben Grodal talks about “feelings of deep meaning” (Grodal 2009: 149). With a nod to Clifford Geertz, Craig Detweiler adopts “thick description” (2007: 47) as do Kutter Callaway altering it to ”thick interpretations” (Callaway 2013: 203).  Frampton states it in a paradox; ”affective intelligence” (Frampton 2006: 166). As a result of the empirical investigation, inspired by Geertz, Detweiler & Callaway, I advocate thick viewing for capturing the viewing process of these specific moments of film experience when profound and intensified emotional interpretations take place. The author As a sociologist of religion, Tomas Axelsons research deals with people’s use of mediated narratives to make sense of reality in a society characterized by individualization, mediatization and pluralized world views.  He explores uses of fiction film as a resource in every day life and he is currently finishing his three year project funded by the Swedish Research Council: Spectator engagement in film and utopian self-reflexivity.

A importância do componente cívico para o funcionamento efetivo de canais participativos como instrumentos de inclusão democrática: um estudo de caso dos Comitês Gestores de Bairro do Programa Nova Baixada

The present research aimed at verifying the performance, as instruments of democratic inclusion, of the managing committees (¿Comitês Gestores de Bairro¿), created by the Government of Rio de Janeiro in the scope of the Nova Baixada Program. Thus, at first, it was presented the concept of democracy, its presuppositions and fragilities, as well as some mechanisms introduced with the objective to extend the effectiveness of this regimen, like the channels of popular participation. It was also demonstrated the importance of the diffusion of civic values for the consolidation of the democracy, mainly in countries like Brazil, where determined cultural characteristics of the society use to act in a negative way in the democratization process. With this propose, some democratic theories, which value aspects as civism and social capital, had been presented and it was also analyzed the cultural elements of the Brazilian society that had negative implications in the performance of the channels of participation introduced in the country. Finally, it was examined the performance of the Comitês Gestores de Bairro (managing committees) of the Nova Baixada Program, trying to establish a relation between the structure of them and the cultural characteristics of our society.

The network of intertextual relations in Naipaul's half a life and magic seeds

Esta dissertação mapeia a rede de relações intertextuais em Half a Life (2001) e sua continuação Magic Seeds (2004), os romances mais recentes do Prêmio Nobel de Literatura de 2001, V. S. Naipaul, como contribuição para o estudo da obra do autor. A noção de intertextualidade permeia os estudos literários, e o termo tem sido largamente empregado desde que foi cunhado por Julia Kristeva nos anos sessenta. Desde então as mais variadas, e muitas vezes divergentes, teorias sobre intertextualidade compartilham a idéia de que um texto só adquire significado pleno na interação com outros textos. A abordagem metodológica proposta é baseada na teoria da transtextualidade de Gérard Genette. Esta escolha implica o estudo de intertextos, paratextos, metatextos, arquitextos e hipertextos que constituem a interface entre os dois romances e outros escritos. O nome do protagonista "William Somerset Chandran" constitui o fio que guia o estudo das várias relações transtextuais nos dois romances. A partir do prenome do protagonista – William – este estudo situa os romances no contexto da tradição do Bildungsroman, e argumenta que estes estabelecem uma paródia arquitextual do gênero na medida em que subvertem seu cerne, ou seja, a formação do caráter do protagonista. O nome do meio do protagonista – Somerset – remete à ficcionalização do escritor Somerset Maugham na narrativa, ao mesmo tempo em que esta desmistifica a ótica ocidental sobre o hinduísmo popularizada por Maugham em The Razor's Edge. O sobrenome do protagonista – Chandran – leva ao estudo do conjunto de referências à origem indiana de Naipaul e o papel desta na produção do autor. Este nome se reporta ao romance de Narayan The Bachelor of Arts, cujo protagonista também é nomeado Chandran. Narayan é um escritor de destaque na literatura anglo-indiana e referência recorrente na obra de Naipaul. Os temas de migração e choque cultural apresentados nos dois romances têm sido presença constante na obra de Naipaul. Esta pesquisa mapeia a relação de continuidade entre os dois romances em questão e o conjunto da obra de Naipaul, salientando o papel da ambientação geográfica da narrativa, marcada pela jornada do protagonista através de três continentes. A teoria da transtextualidade é uma ferramenta operacional para a pesquisa, a qual examina a densidade das referências geográficas, históricas e literárias em Half a Life e Magic Seeds, visando aportar elementos para o estudo da produção literária de Naipaul, na medida em que estes romances recentes condensam e revisitam a visão de mundo deste autor.

Estudos sobre o conceito de inteligência e suas implicações

O objetivo deste trabalho é demonstrar que o conceito de inteligência apresenta implicações ideológicas. Para tal fim foi realizado um estudo das principais medidas e teorias sobre a inteligência. A partir deste estudo verificou-se que: 1) As medidas mais sofisticadas precederam as teorias mais formalizadas. A inteligência é um conceito que surgiu de um pólo muito mais técnico que teórico; 2) O primeiro teste padronizado de inteligência foi elaborado a pedido das autoridades escolares francesas. Segundo Althusser (1976), a instituição escolar é um aparelho idelógico do estado, tendo como finalidade garantir que a classe dominante exerça o seu domínio. 3) A fidedignidade é a expressão da conservaçao. O QI não varia com o tempo porque os testes foram construídos para este fim. 4) O critério de validação de um teste de inteligência, direta ou indiretamente, é o sucesso escolar. Desta forma não é necessário um teste para separar alunos brilhantes dos não brilhantes; basta que sejam usadas as notas obtidas pelos alunos nos exames escolares. 5) Algumas variáveis foram, relacionadas com o QI. Especial atenção foi dada à relação entre raça e QI. Foram apresentadas posições que atribuem a fatores genéticos a diferença de QI entre as raças, posições que atribuem esta diferença a fatores ambientais e um terceiro grupo que atribuem a mesma diferença a fatores genéticos-ambientais. 6) As teses geneticistas foram e são acusadas de serem ideológicas, pois, atribuindo-se diferenças a fatores genéticos, elimina-se a possibilidade de questionar o meio social (Caráter conservador da ideologia). 7) As teses ambientalistas também são ideológicas por aceitarem como verdadeira sua concepção, excluindo-se o componente genético. (Caráter deformante da ideologia). 8) As provas experimentais não podem resolver estas questões. Adotar uma ou outra posição é uma questão de valor. A partir do anteriormente exposto fica claro que o objetivo do trabalho não é optar por ou defender uma entre as explicações das diferenças relativas ao QI e, sim, mostrar que tais explicações assumem um caráter ideológico.

Uma interpretação da psicogênese e da sociogênese do desenvolvimento moral

O objetivo deste estudo volta-se para uma análise a nível teórico,da construção de normas. constitutivas do sistema moral aptas a direcionarem a conduta humana. Três referenciais básicos foram estabelecidos como pla taformas para o estudo: A Crítica da Razão Prática de I. Kant e a avaliação do caráter neces5ário da norma. bem como a dificuldade de transpor para o plano histórico e empírico. critérios de universalidade inerentes ao "imperativo categórico". A categorização dos valores de E. Spranger forneceu elementos para proceder a uma análise da sociogênese das normas, partindo de critérios valorativos. culturalmente estabelecidos, aptos a quantificar conteúdos para a moral. Finalmente. a perspectiva piagetiana ofereceu as bases para uma avaliação da psicogênese como construção formal dos sistemas de regras, que compõem a moral humana. O estudo aqui realizado estabelece seus próprios limites dentro dos três contextos acima selecionados por constituirem uma interpretação prefixada que viza harmonizar tais posiçoes. Estas fronteiras. assim definidas. justificam portanto o caráter circunscrito. e sem pretensões de ser exaustivo na matéria que o presente trabalho se propõe evidenciar.

The power of the purse : what do the data say on US federal budget allocation to the states?

This paper provides new evidence on the determinants of the allocation of the US federal budget to the states and tests the capability of congressional, electoral and partisan theories to explain such allocation. We find that socio-economic characteristics are important explanatory variables but are not sufficient to explain the disparities in the distribution of federal monies. First, prestige committee membership is not conducive to pork-barrelling. We do not find any evidence that marginal states receive more funding; on the opposite, safe states tend to be rewarded. Also, states that are historically "swing" in presidential elections tend to receive more funds. Finally, we find strong evidence supporting partisan theories of budget allocation. States whose governor has the same political affiliation of the President receive more federal funds; while states whose representatives belong to a majority opposing the president party receive less funds.

Value-for-money e geração de valor público na atuação das organizações sociais de saúde : contribuições para o governo do estado de São Paulo

O fato de que o Estado brasileiro deve, de acordo com sua Carta Magna, garantir o direito de seus cidadãos à saúde não significa, necessariamente, que a provisão destes serviços tem de ser feita diretamente pelo poder público. As parcerias com organizações sociais, previstas na Lei Federal 9.637/1998 e regulamentadas pelos Contratos de Gestão, pretendem oferecer uma alternativa à eficiência, agilidade e flexibilidade na assistência à saúde. Entretanto, a estrutura dos contratos de gestão com Organizações Sociais de Saúde (OSS), elaborada com a pactuação de metas e indicadores de desempenho, não pode ser considerada, isoladamente, como fator garantidor da prestação adequada de tais serviços públicos. É fundamental considerar neste contexto os arranjos organizados pelo poder público para assegurar que os serviços oferecidos representam o que, de fato, os cidadãos consideram valor. O presente trabalho tem como objeto as parcerias com OSS no âmbito do governo do estado de São Paulo. As entrevistas realizadas e as pesquisas empreendidas na confecção deste estudo revelam que, caso se pretenda trabalhar com estas parcerias sob uma perspectiva de value-for-money e geração de valor público, faz-se necessário aprimorar os mecanismos de escuta aos cidadãos, os arranjos de governança colaborativa entre entes federados, o alinhamento com órgãos de controle e, sobretudo, qualificar a capacidade organizacional do Estado e das OSS, por meio da revisão das metas e indicadores dispostos nos contratos de gestão.

Sustainability indexes: why join in? A study of the Corporate Sustainability Index (ISE) in Brazil

In the past decade, indicators have been created to assess the sustainability performance of companies listed in stock exchange markets. Academics and practitioners expect companies to benefit from being listed in such indexes, but evidence of value creation is still scarce. Since virtually all studies about the Corporate Sustainability Index (ISE) of the S~ ao Paulo Stock Exchange (Brazil) e the object of the present study e focused on the value of shares, we initially looked for answers in the finance theory. We collected secondary data about the financial and economic performance of companies forming the ISE's ‘theoretical portfolio’, as these kinds of indexes are also known. In a second stage, we sought additional motivations for companies to make efforts to be listed in the index. We collected additional data and interviewed representatives of key companies listed in the ISE, as well as industry leaders who chose not to participate in the selection process. The results support the main propositions of the institutional theory, as well as the ‘pays to be green’ literature e that the intangible value created by voluntary environmental initiatives, such as access to knowledge, new capabilities and reputational gain, better explain the efforts companies make to be listed in the ISE index

Boundary decisions of the firm: make, buy, cooperate

Firms are not atomistic hierarchies only linked with one another at arm’s-length distance in markets. Instead, a myriad of long-lived, highly cooperative relationships between suppliers and customers are pervasively found in the B2B world. And it is within those enmeshed relationships and networks that the co-evolution of capabilities and business specialisms is brought about and developed. If that is the actual ‘topography’ of the business landscape, then the coordination of economic activities in general, and the boundary decisions of each and every firm in particular, are unlikely to be reduced to a (dual) choice between ‘making’ or ‘buying’. Inter-firm cooperation is in itself a third governance structure, in alternative to the hierarchical and the market modes of coordination. And, what is also equally important to note, it is through the make-or-buy-or-cooperate decisions that the (embedded) firm is able to change its nature and scope, redefine its (fuzzy) boundaries, and thus adapt to an ever-changing business setting.

Circulating leukocyte heat shock protein 70 (HSP70) and oxidative stress markers in rats after a bout of exhaustive exercise

A novel method to measure oxidative stress resulting from exhaustive exercise in rats is presented. In this new procedure we evaluated the erythrocyte antioxidant enzymes, catalase ( CAT) and glutathione reductase (GR), the plasma oxidative attack markers, reactive carbonyl derivatives (RCD) and thiobarbituric reactive substances (TBARS). Muscular tissue damage was evaluated by monitoring plasma creatine kinase (CK) and plasma taurine ( Tau) concentrations. Also, we monitored total sulphydryl groups (TSG) and uric acid (UA), and the level of the 70 kDa heat shock protein (HSP70) in leukocytes as a marker of oxidative stress. In the study we found a correspondence between erythrocyte CAT and GR activities and leukocyte HSP70 levels, principally 3 h after the acute exercise, and this suggested an integrated mechanism of antioxidant defense. The increase in levels of plasma Tau was coincident with the increasing plasma levels of CK and TBARS, principally after two hours of exercise. Thus tissue damage occurred before the expression of any anti-oxidant system markers and the monitoring of Tau, CK or TBARS may be important for the estimation of oxidative stress during exhaustive exercise. Furthermore, the integrated analyses could be of value in a clinical setting to quantify the extent of oxidative stress risk and reduce the need to perform muscle biopsies as a tool of clinical evaluation.

Escola e gênero : representações de gênero na escola

The study Escola e Gênero: representações de gênero na escola show us the social man made, starting of an analysis in the having fun time in the children´s life and how it´s an important aspect of the building childish universe simbolic. My analysis started in a children´s daily at school and how they noticed the play value od dominant society. Our propouse is think about the linking between ideology, representations and gender like the children´s knowledge in the school activities. The toy, an instrument which is noticed and exist in the funny activities, is full of cultural concepts of male and female parts. Your color, lines, functions and the way you manipulate is driven of gender cathegories. In the scool, the ideological concepts have it´s important way which is to domesticate the feelings, the desires; categorize and normalize them without be known by the educational employers. In the children´s education, the funny time is noticed by others ways and turned as important as others subjects. By the way it´s not noticed by the school, like another thing which isn´t a funny moment. And it´s exactly here in the school funny time, the school did your cultural power of separete the gender and your extencions, feed by the society, generaly, in favor of the man whose woman is your subordinate. This ways of analysis help the society and the school universe about the funny time e how they are important in the Man made life. And how the toys bring the concepts and addicted thinking, ideological which put the power in the stages, without equal, addicted feelings around the gender concepts. I read and used the theories of Kishimoto, Berger & luckmann, Brougère, Sousa Filho, Bourdieu, Badinter, Geertz, Grossi, Louro, Foucault, among others
