Dynamical properties of nuclear and stellar matter and the symmetry energy

The effects of density dependence of the symmetry energy on the collective modes and dynamical instabilities of cold and warm nuclear and stellar matter are studied in the framework of relativistic mean-field hadron models. The existence of the collective isovector and possibly an isoscalar collective mode above saturation density is discussed. It is shown that soft equations of state do not allow for a high density isoscalar collective mode, however, if the symmetry energy is hard enough an isovector mode will not disappear at high densities. The crust-core transition density and pressure are obtained as a function of temperature for $\beta$-equilibrium matter with and without neutrino trapping. An estimation of the size of the clusters formed in the non-homogeneous phase as well as the corresponding growth rates and distillation effect is made. It is shown that cluster sizes increase with temperature, that the distillation effect close to the inner edge of the crust-core transition is very sensitive to the symmetry energy, and that, within a dynamical instability calculation, the pasta phase exists in warm compact stars up to 10 - 12 MeV.Comment: 16 pages, 10 figures.

Sentiment and behaviour annotation in a corpus of dialogue summaries

This paper proposes a scheme for sentiment annotation. We show how the task can be made tractable by focusing on one of the many aspects of sentiment: sentiment as it is recorded in behaviour reports of people and their interactions. Together with a number of measures for supporting the reliable application of the scheme, this allows us to obtain sufficient to good agreement scores (in terms of Krippendorf's alpha) on three key dimensions: polarity, evaluated party and type of clause. Evaluation of the scheme is carried out through the annotation of an existing corpus of dialogue summaries (in English and Portuguese) by nine annotators. Our contribution to the field is twofold: (i) a reliable multi-dimensional annotation scheme for sentiment in behaviour reports; and (ii) an annotated corpus that was used for testing the reliability of the scheme and which is made available to the research community

Transcendência na cinantropologia de Manuel Sérgio

This article seeks to analyze the contribution of Portuguese philosopher Manuel Sergio to Religious Studies. The author dedicated his long academic life to the study of sports, but with a peculiar humanistic perspective. Instead of focusing on performance, the author focuses on the Human being who moves. This is what he defines as "Kinanthropology". Transcendence is a major element in this proposal. In this article, after presenting Sergio's fundamental anthropological framework and his understanding of "human kinetics", three of his possible theoretical contributions to Religious Studies are explored: 1. in the way he sees the relation between transcendence and religion; 2. in the way he opens corporeity to transcendence; and 3. in the way he seems to rehabilitate motion as a topic for religious and theological discourse.Este artigo investiga o contributo do filósofo português Manuel Sérgio para as Ciências da Religião. O autor dedicou a sua longa vida académica ao estudo do desporto, mas com uma perspectiva humanística peculiar. Em vez de se focar na performance, foca-se no ser humano que se move. É isto que Manuel Sérgio propõe como cinantropologia. A transcendência é um elemento decisivo desta proposta. Neste artigo, após se apresentar o enquadramento antropológico fundamental de Sérgio e o seu entendimento de “motricidade humana”, são explorados três tópicos como suas eventuais contribuições teóricas: 1. na forma como ele vê a relação entre transcendência e religião; 2. na forma como ele abre a corporeidade à transcendência; e 3. na forma como ele parece reabilitar o movimento como elemento do discurso religioso e teológico.info:eu-repo/semantics/publishedVersio

A ASSISTÊNCIA SOCIAL E SEUS USUÁRIOS: UMA ANÁLISE DOS BENEFICIÁRIOS DO CARTÃO-ALIMENTAÇÃO EM MARINGÁ/PR

Resumo O presente artigo é resultado estudos investigativos concluídos na cidade de Maringá/PR e tem por objetivo compreender a visão dos usuários do CRAS Ney Braga acerca da assistência social enquanto direito social. Para tanto, entre os meses de abril e junho de 2015 foram entrevistados usuários beneficiários do cartão-alimentação (benefício eventual do município lócus da pesquisa). Em linhas gerais, pode-se dizer que, mesmo após 27 anos dos artigos 203 e 204 da Constituição Federal e sua consequente entrada no campo da Seguridade Social, a percepção da política de assistência social enquanto direito ainda não está alicerçada na compreensão dos entrevistados. Tal constatação deve repercutir nos reais avanços e inúmeros desafios que a política ainda possui nos dias atuais

A model for the classification of companies credit risk

O processo de gerenciamento de risco de crédito em instituições financeiras vem passando por uma revisão ao longo dos últimos anos. Nesse contexto, diversas novas técnicas de mensuração de risco de crédito e tomadores têm sido desenvolvidas e implementadas por grandes Bancos. O objetivo desta pesquisa é desenvolver um modelo de classificação de risco para avaliar o risco de crédito de empresas no mercado brasileiro. O modelo foi construído com base em uma amostra de empresas de capital aberto classificadas como solventes ou insolventes no período entre 1994 e 2004. A técnica estatística utilizada no desenvolvimento do modelo foi a regressão logística. As variáveis independentes são índices financeiros calculados a partir das demonstrações contábeis e utilizados para representar a situação econômico-financeira das empresas. A validação do modelo foi efetuada utilizando o método Jackknife e uma Curva ROC. Os resultados do estudo indicam que o modelo de classificação de risco desenvolvido prevê eventos de default com um ano de antecedência com bom nível de acurácia. Os resultados, também, indicam que as demonstrações contábeis contêm informações que possibilitam a classificação das empresas como prováveis solventes ou prováveis insolventes.The process of credit risk management in financial institutions has been revised in recent years. In this context, large banks have developed and implemented several new techniques for measuring borrowers credit risk. This research aims to develop a risk classification model to assess the credit risk of companies in the Brazilian market. The model was built based on a sample of publicly traded companies classified as solvent or insolvent during the period from 1994 to 2004. Logistic regression was used to develop the model. The independent variables of the model are financial ratios, calculated from the financial statements and used as proxies of companies economic and financial situation. The validation of the model was done using the Jackknife method and a ROC Curve. The results of the study indicate that the risk classification model developed predicts default events one year prior to failure with good level of accuracy. The results also indicate that financial statements contain information that allow for the classification of companies as probably solvent or probably insolvent

In-season internal and external training load quantification of an elite European soccer team

Elite soccer teams that participate in European competitions need to have players in the best physical and psychological status possible to play matches. As a consequence of congestive schedule, controlling the training load (TL) and thus the level of effort and fatigue of players to reach higher performances during the matches is therefore critical. Therefore, the aim of the current study was to provide the first report of seasonal internal and external training load that included Hooper Index (HI) scores in elite soccer players during an in-season period. Nineteen elite soccer players were sampled, using global position system to collect total distance, high-speed distance (HSD) and average speed (AvS). It was also collected session rating of perceived exertion (s-RPE) and HI scores during the daily training sessions throughout the 2015-2016 in-season period. Data were analysed across ten mesocycles (M: 1 to 10) and collected according to the number of days prior to a one-match week. Total daily distance covered was higher at the start (M1 and M3) compared to the final mesocycle (M10) of the season. M1 (5589m) reached a greater distance than M5 (4473m) (ES = 9.33 [12.70, 5.95]) and M10 (4545m) (ES = 9.84 [13.39, 6.29]). M3 (5691m) reached a greater distance than M5 (ES = 9.07 [12.36, 5.78]), M7 (ES = 6.13 [8.48, 3.79]) and M10 (ES = 9.37 [12.76, 5.98]). High-speed running distance was greater in M1 (227m), than M5 (92m) (ES = 27.95 [37.68, 18.22]) and M10 (138m) (ES = 8.46 [11.55, 5.37]). Interestingly, the s-RPE response was higher in M1 (331au) in comparison to the last mesocycle (M10, 239au). HI showed minor variations across mesocycles and in days prior to the match. Every day prior to a match, all internal and external TL variables expressed significant lower values to other days prior to a match (p<0.01). In general, there were no differences between player positions. Conclusions: Our results reveal that despite the existence of some significant differences between mesocycles, there were minor changes across the in-season period for the internal and external TL variables used. Furthermore, it was observed that MD-1 presented a reduction of external TL (regardless of mesocycle) while internal TL variables did not have the same record during in-season match-day-minus.: The authors state that there were no salaries’ fund from a tobacco company.

In-season training load quantification of one-, two- and three-game week schedules in a top European professional soccer team

Top European soccer teams that play in UEFA competitions often participate in one, two- or three-games per week. Therefore, it is necessary to ensure optimal match-day performance and full recovery. The aim of this study was to quantify internal and external training load (TL) within five microcycles: M1 and M2 - one-game weeks; M3 and M4 - two-game weeks; M5 - three-game week). Thirteen elite soccer players participated in this study. A global positioning system (GPS) was used to measure the total distance covered and distances of different exercise training zones (1-5), the session ratings of perceived exertion (s-RPE) scores and the amount of creatine kinase (CK) created during daily training sessions for the 2015-2016 in-season period. The data were analysed with respect to the number of days prior to a given match. The main results indicate that there was a significant difference in training intensity for zone 1 between M2 and M4 (4010.2 ± 103.5 and 4507.6 ± 133.0 m, respectively); a significant difference in training intensity for zone 3 between M1 and M5 (686.1 ± 42.8 and 801.2 ± 61.2 m, respectively); a significant difference in the duration of the training sessions and matches between M2 and M5 (69.2 ± 2.1 and 79.6 ± 2.3) and M3 and M5 (69.7 ± 1.0 and 79.6 ± 2.3); and finally, there was a significant difference in CK between M3 and M2 (325.5 ± 155.0 and 194.4 ± 48.9). Moreover, there was a significant decrease in TL in the last day prior to a match, for all microcycles and all variables. There was no significant difference with respect to s-RPE. This study provides the first report of daily external and internal TLs and weekly accumulated load (training sessions and match demands) during one, two, and three-game week schedules in a group of elite soccer players. Expected significant differences are found in daily and accumulated loads for within- and between-game schedules. A similar pattern is exhibited for one- and two-game week microcycles regarding the day before the match, which exhibits a decrease in all variables. Despite the different number of games played per week, TL remain similar between microcycles for zone 2 and 5, plus s-RPE.This project was supported by the National Funds through FCT—Portuguese Foundation for Science and Technology (UID/DTP/04045/2013) and the European Fund for Regional Development (FEDER) allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145-FEDER-006969)—competitiveness and internationalization (POCI).

Contos gauchescos pelo sertão : a personagem no regionalismo

Este trabalho analisa a composição literária das personagens em contos regionalistas da passagem do século XIX para o XX, no âmbito da Literatura Brasileira. Para tanto, além do conjunto de contos selecionados e das obras em que são publicados, analisamos as concepções apresentadas em Os Sertões, de Euclides da Cunha; assim como a maneira como são representadas no texto, a fim de bem compreender – partindo de obra prestigiada e reconhecida de imediato, quando da publicação – sob quais parâmetros se estabelecem as visões correntes sobre a constituição étnica do povo brasileiro (especialmente daquele contingente vivente nos sertões), tal como compreendido no período pelos pensadores envolvidos no debate público sobre o tema, conforme a exposição e tematização realizadas. Este trabalho ocupa-se, pois, da representação das personagens nesses contos representativos do gênero, pressupondo que sejam feitos com, entre outros fins, o de compreender um coletivo humano particular, inserindo-se em um debate que era público e pujante. Debruando-se, afinal, àquele povo, notadamente oriundo de uma parte peculiar do território nacional, caracterizada por ser interiorana, de meio natural inalterado pala ação humana, ou rural; de qualquer maneira, de baixa concentração populacional e parco investimento humano em infraestrutura.This work analyze the literary construction of characters in regionalist short stories (literary genre from Brazilian Literature) from turn of the Nineteenth century to Twenty century. For this, in addition to the set of selected short stories and the works in which they are published, we analyze the concepts presented in Os Sertões by Euclides da Cunha (translated by Samuel Putnam as Rebellion in the Backlands and retranslated, as Backlands The Canudos, by Elizabeth Lowe); as well as the way they are represented in the text, in order to understand well - starting from a prestigious work and recognized immediately, when the publication - under which parameters are established the current views on the ethnic constitution of the Brazilian people (especially of that contingent living in the backlands), as understood in the period by the thinkers involved in the public debate on the subject, according to the exposition and thematization carried out. This work, therefore, deals with the representation of the characters in these tales, representative of the genre, assuming that they are done with, among other purposes, the understanding of a particular human collective, entering into a debate that was public and vigorous. After all, turning to that people, notably coming from a peculiar part of the national territory, characterized by being interior, natural environment unchanged human action, or rural; In any case, of low population concentration and little human investment in infrastructure

Processos de Estrangeirização Discente: o Aluno e a Ciência sem Significado

O texto que se segue tem como foco principal a abordagem da problemática da linguagem na geografia e como no decorrer dos períodos os modos de produção condicionaram a interpretação do espaço bem como sua representação criando um habitus e um modus operandi hegemônico que acaba por homogeneizar as visões de mundo em torno de um único plano ideológico e uma única verdade possível. Verdade essa que só se expressa como possibilidade e como crença na configuração das ciências com seu viés metafísico que separa sujeito e objeto em um dualismo que instiga os pesquisadores por um caminho que leva às interpretações universalizadoras e genéricas que estancam o processo do conhecimento e eliminam os processos históricos da equação como se houvesse uma cúpula além da realidade mundana onde o cientista pudesse observar e catalogar as verdades absolutas sem precisar atentar para a práxis humana. As reflexões que se encontram nesse texto tiveram origem e foram orientadas pela leitura da tese de doutoramento da Professora Doutora Ângela Massumi Katuta O Estrangeiro no Mundo da Geografia de 2004 que realiza um profundo estudo sobre a geografia e as abordagens que essa ciência faz
