Stabilising Merger Waves: An Agent-Based Networked Model of Market Stability
No full textThe world's markets are increasingly interconnected, imposing additional challenges for both regulators and market participants. This paper considers the effect of inter-market dependencies on the spread of endogenously generated merger waves. Though merger activity can generate efficiency gains, it disrupts market competition and can lead to negative effects for consumers. The conditions under which disruptive merger activity can spread to otherwise stable markets are identified. It is also shown which inter-market dependency configurations are more likely to lead to situations in which the stability of some markets can be disrupted by merger activity in others
Solutions of the Schrödinger-Poisson problem concentrating on spheres. II. Existence
No full textThe SchroedingerPoisson system describes standing waves for the nonlinear Schroedinger equation interacting with the electrostatic field.
We deal with the semiclassical states for this system and prove the existence of radial solutions concentrating on spheres in the presence of an external potential and with a non-constant density charge.
In particular, we show that the necessary conditions obtained in Part I are also sufficient if suitable non-degeneracy conditions are assumed.
We use a perturbation technique in a variational setting

The formation of the Brazillian developmental State in the work of Octavio Ianni
No full textOrientador: Walquiria Gertrudes Domingues Leão RegoDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Filosofia e Ciencias HumanasResumo: A presente pesquisa de dissertação de mestrado tem como objetivo examinar parte da produção teórica do Sociólogo Octávio Ianni (1926-2004) no período em que o autor analisou as transformações ocorridas no Estado brasileiro durante a industrialização (1930-1964). Especificamente, o objetivo desta pesquisa é analisar o período compreendido entre as décadas de 1960 e 1970 quando Ianni publicou obras fundamentais e polêmicas a respeito das modificações estruturais operadas no Estado brasileiro. As pesquisas realizadas pelo autor neste período a respeito das vinculações entre o Estado brasileiro e a economia inserem-se num estudo mais amplo realizado pelo Centro de Sociologia Industrial e do Trabalho (CESIT)1, vinculado a cadeira de Sociologia I, sob a coordenação do professor Florestan Fernandes. O projeto geral dessa pesquisa intitulava-se "Economia e sociedade no Brasil: Análise sociológica do subdesenvolvimento" e tinha outros importantes pesquisadores vinculados a esse empreendimento tais como: Fernando Henrique Cardoso, Maria Sylvia de Carvalho Franco, Luiz Pereira, Paul Singer, Marialice Mencarini Foracchi, Leôncio Martins Rodrigues, Lourdes Sola, etc. Em suma, na década de 1960, Ianni, juntamente com Florestan Fernandes e outros pesquisadores, empreendeu uma investigação sobre a mudança social que estava em curso no Brasil no período devido à rápida industrialização realizada neste país. Coube ao autor investigar a relação entre a atividade econômica e o poder público. Por isto, focaliza em sua pesquisa a atuação estatal frente à passagem de uma economia primária exportadora para uma economia substitutiva de importações. Segundo Ianni, o Estado brasileiro será o centro das decisões com relação à expansão das forças produtivas da economia capitalista. Ao longo deste período, a esfera estatal amplia sua atuação no sentido de corrigir os desequilíbrios e as distorções surgidas na economiaAbstract: The following master's thesis research has the goal of examining part of the theoretical work of the sociologist Octávio Ianni (1926-2004) during the time in which the author analyzed the transformation undergone by the Brazilian State in the time of the industrialization (1930-1964). Specifically, the objective of this research is to analyze the period between the 1960 and 1970 decades when Ianni published fundamental and polemic works in the structural modifications in the Brazilian State. The research conducted by the author in this period about the links between the Brazilian State and the economy is part of a broader study by the Center of Industrial and Work Sociology (CESIT), linked to the chair of Sociology I, under the coordination of the professor Florestan Fernandes. The general project of this research was entitled "Economy and society in Brazil: A sociological analysis of underdevelopment" and had other important researchers tied to the enterprise such as: Fernando Henrique Cardoso, Maria Sylvia de Carvalho Franco, Luiz Pereira, Paul Singer, Marialice Mencarini Foracchi, Leôncio Martins Rodrigues, Lourdes Sola, etc. In short, in the 1960s, Ianni together with Florestan Fernandes and other researchers undertook an investigation on the social change that was on course in Brazil in the period due to the fast industrialization in the country. It was up to the author to investigate the relationship between the economical activity and the public power. Therefore, his research focuses on the state action regarding the passage from a primary exporting economy to an importation replacement economy. According to Ianni, the Brazilian State will be the center of decisions in regard to the expansion of productive forces of the capitalist economy. During this period, the state sphere expands its actuation to correct the unbalances and distortions arising in the economyMestradoSociologiaMestre em Sociologi
Case Report: A case of pediatric persistent refractory ITP responsive to avatrombopag
No full textImmune thrombocytopenia (ITP) is a rare hematologic disorder characterized by low platelet counts due to an immune-mediated destruction of platelets. While corticosteroids, intravenous immunoglobulin (IVIG) are the mainstays of treatment, a subset of patients may remain refractory to these therapies. Here, we present a case of a 6-year-old girl diagnosed with refractory ITP, who failed to respond to standard therapies but showed a remarkable clinical improvement with avatrombopag, a thrombopoietin receptor agonist.

Octavio Ianni and his intelectual trajectory beggining: a new interpretation about “The Racial Question”
No full textNesta pesquisa fazemos uma análise de parte da corrente de pensamento político-social brasileiro formada na Cadeira I de Sociologia Uspiana. Através do estudo de algumas obras sobre a temática racial desenvolvidas por Octavio Ianni, buscamos compreender a linha de pensamento acerca do conteúdo no período entre 1957 a 1961. O trabalho consiste na investigação de determinadas obras, por meio de uma reconstrução histórico-sociológica na intenção de entender as diferentes perspectivas metodológicas utilizadas pelo autor em sua dissertação de mestrado e em sua tese de doutorado, quando se apropria do eixo de análise marxista para a análise do sistema escravocrata e sua abolição no Brasil. Os trabalhos sobre a questão racial desenvolvidos por Octavio Ianni trouxeram grande contribuição ao modo pelo qual o tema vinha sendo pesquisado desde que fora abolida a escravatura no Brasil. Os estudos ajudaram a diagnosticar não apenas este fenômeno mas também o desenvolvimento capitalista em curso no Brasil desde o final do século XIX.We make in this research an analysis about Brazilian social political thought formed at Cadeira I de Sociologia Uspiana. Through the study of some works about the racial subject developed by Octavio Ianni we seek to comprehend a thought line about the content in the period between 1957 and 1961. The dissertation aims the investigation of specific works through a sociological-historic reconstruction intending to understand the different methodological perspectives used by the author in his master’s degree dissertation and PHD thesis, when adopting the Marxist perspective to analyze the slavery system and its disintegration in Brazil. The works about the racial question developed by Octavio Ianni brought important contributions to the way which the subject has been researched in Brazil since the slavery abolition. The studies helped to diagnostic not just this phenomenon but also the capitalist development since the 19th centuryCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
