O Uso de Contratos Futuros para Prote o de Ativo e Passivo Circulantes contra a Flutua o na Taxa de Juros de Curto Prazo
Felipe Garran,Almir Ferreira de Sousa,Carlos de Mori Luporini
Revista de Finan?as Aplicadas , 2010,
Abstract: O presente artigo tem como objetivo apresentar um modelo de prote o de ativos e passivos cir-culantes a varia es nas taxas de juros de curto prazo. Para tanto, foi utilizada uma carteira de contratos futuros de taxas de juros que permite a forma o de carteiras de ativos e passivos com dois parametros iguais: o valor presente e o prazo médio (duration) das carteiras. A forma o des-sas carteiras parte do fundamento que um conjunto de ativos ou passivos pode ser representado por um único título sintético e ainda, que os ativos e passivos circulantes de uma organiza o n o-financeira podem ser entendidos como títulos com maturidade igual ao prazo médio dessas contas de ativos ou passivos. Foi apresentado um exemplo numérico que mostra a imuniza o proporcio-nada pelo modelo. Na formula o do modelo considerou-se uma estrutura a termo de taxas de juros constante (flat) com deslocamento paralelo no instante seguinte. Palavras-chave: renda fixa, derivativos, futuros, duration, imuniza o

Abstract: Este trabalho visa o estudo do or amento empresarial como uma ferramenta para apoiar as decis es de controle de gest o em indústrias farmacêuticas de médio porte. Como objetivos específicos, o estudo verifica se as indústrias têm um sistema de informa es gerenciais de contabilidade que atende às necessidades dos gestores, a ado o de uma estrutura formal para o planejamento de longo e curto prazo os resultados, o padr o aplicado na elabora o do or amento empresarial e avalia o dos gestores do processo or amental que tem sido adotado. O referencial teórico apresenta o ponto de vista de renomados autores e está dividido em quatro partes. O primeiro descreve decis es gerenciais, bem como o sistema de informa o gerencial contábil. A segunda é sobre o planejamento estratégico. Em seguida, o or amento empresarial e, finalmente, o controle de gest o. A metodologia de pesquisa adotada foi o estudo de caso múltiplo no qual cinco empresas participaram. Os dados foram coletados por pesquisadores através de entrevistas individuais com os gerentes administrativo-financeiro das empresas. A conclus o apresentada por este trabalho revela que o or amento de gest o corporativa é utilizado pelos gestores das cinco empresas como uma ferramenta de apoio para as decis es e controle gerencial e que o processo or ametal adotado atende ao necessário, mas ainda há a necessidade de melhorias.
A Markovian Model Market - Akerlof's Lemmons and the Asymmetry of Information
Paulo F. C. Tilles,Fernando F. Ferreira,Gerson Francisco,Carlos de B. Pereira,Flavia Mori Sarti
Quantitative Finance , 2009,
Abstract: In this work we study an economic agent based model under different asymmetric information degrees. This model is quite simple and can be treated analytically since the buyers evaluate the quality of a certain good taking into account only the quality of the last good purchased plus her perceptive capacity \beta . As a consequence the system evolves according to a stationary Markovian stochastic process. The value of a product offered by the seller increases with quality according to the exponent \alpha, which is a measure of technology. It incorporates all the technological capacity of production systems such as education, scientific development and techniques that change the productivity growth. The technological level plays an important role to explain how the asymmetry of information may affect the market evolution in this model. We observe that, for high technological levels, the market can control adverse selection. The model allows us to compute the maximum asymmetric information degree before market collapse. Below this critical point the market evolves during a very limited time and then dies out completely. When \beta is closer to 1(symmetric information), the market becomes more profitable for high quality goods, although high and low quality markets coexist. All the results we obtained from the model are analytical and the maximum asymmetric information level is a consequence of an ergodicity breakdown in the process of quality evaluation.
Multiple drug resistance protein (MDR-1), multidrug resistance-related protein (MRP) and lung resistance protein (LRP) gene expression in childhood acute lymphoblastic leukemia
Valera, Elvis Terci;Scrideli, Carlos Alberto;Queiroz, Rosane Gomes de Paula;Mori, Bianca Maria Ortelli;Tone, Luiz Gonzaga;
Sao Paulo Medical Journal , 2004, DOI: 10.1590/S1516-31802004000400007
Abstract: context: despite the advances in the cure rate for acute lymphoblastic leukemia, approximately 25% of affected children suffer relapses. expression of genes for the multiple drug resistance protein (mdr-1), multidrug resistance-related protein (mrp), and lung resistance protein (lrp) may confer the phenotype of resistance to the treatment of neoplasias. objective: to analyze the expression of the mdr-1, mrp and lrp genes in children with a diagnosis of acute lymphoblastic leukemia via the semiquantitative reverse transcription polymerase chain reaction (rt-pcr), and to determine the correlation between expression and event-free survival and clinical and laboratory variables. design: a retrospective clinical study. setting: laboratory of pediatric oncology, department of pediatrics, faculdade de medicina de ribeir?o preto, universidade de s?o paulo, brazil. methods: bone marrow aspirates from 30 children with a diagnosis of acute lymphoblastic leukemia were assessed for the expression of messenger rna for the mdr-1, mrp and lrp genes by semi-quantitative rt-pcr. results: in the three groups studied, only the increased expression of lrp was related to worsened event-free survival (p = 0.005). the presence of the common acute lymphoblastic leukemia antigen (calla) was correlated with increased lrp expression (p = 0.009) and increased risk of relapse or death (p = 0.05). the relative risk of relapse or death was six times higher among children with high lrp expression upon diagnosis (p = 0.05), as confirmed by multivariate analysis of the three genes studied (p = 0.035). discussion: cell resistance to drugs is a determinant of the response to chemotherapy and its detection via rt-pcr may be of clinical importance. conclusions: evaluation of the expression of genes for resistance to antineoplastic drugs in childhood acute lymphoblastic leukemia upon diagnosis, and particularly the expression of the lrp gene, may be of clinical relevance, and should be the object of prosp

Abstract: the primary colorectal lymphoma is a rare disease (0.2 to 0.6% of all colonic neoplasias), that has a worse prognosis than primary gastric lymphoma or colon adenocarcinoma. the poor signals makes the early diagnosis difficult. the objectives of this report is to describe a case of primary colon lymphoma, revise diagnosis criteria and treatment.
The monetary transmission mechanism in Brazil: evidence from a var analysis
Luporini, Viviane;
Estudos Econ?micos (S?o Paulo) , 2008, DOI: 10.1590/S0101-41612008000100001
Abstract: this article presents evidence on the interest channel of the monetary policy for the brazilian economy of the 1990s analyzing the effects of an unexpected change in the baseline interest rate on output, prices and the exchange rate in a vector autoregression system. our main results are: a) a tightening in the monetary policy affects economic activity immediately, reducing the rate of growth of real gdp; b) the exchange rate and prices are affected only after a time interval, with inflation assuming a downward trend only two months after the monetary shock; c) results do not change when the specification is controlled for international conditions, commodity prices or other measures of inflation and economic activity; d) monetary shocks have a significant impact on the volatility of output and inflation in the benchmark model e) monetary shocks have a significant impact on the volatility of the debt/gdp ratio in the control-model.
Sustainability of the Brazilian fiscal policy and central bank independence
Luporini, Viviane;
Revista Brasileira de Economia , 2000, DOI: 10.1590/S0034-71402000000200004
Abstract: this paper analyzes the sustainability of fiscal policy in brazil since the financial reform of 1965 and discusses how the relationship between the treasury and the central bank has determined the federal government's capacity to finance itself. a sustainable policy is defined as one such that the discounted government debt as a ratio to the gdp is backed by expected primary surpluses of equal present-value. in the context of an infinite-horizon framework, sustainability is tested through the mean-zero stationarity of the discounted debt/gdp ratio. although the overall results indicate sustainability, tests on subsamples show that the fiscal policy was sustainable prior to 1980, but it assumed an unsustainable path during the 80's and early 90's.
El carácter práctico de la teología
de Mori,Geraldo;
Teología y vida , 2010, DOI: 10.4067/S0049-34492010000300003
Abstract: this article shows how the practical aspect is a fundamental constituent of the theological endeavor. such practical aspect, which is obvious for theology as stated in the thesis of this study, is portrayed as being problematic since it has given rise to entry points so diverse that, in the end, they question the legitimacy and scientificity of practical theology.
Una lectura teológica de la realidad: A cuáles nuevos saberes recurrir o con qué saberes contar?
Geraldo De Mori
Teología y vida , 2012,
Abstract: Tras un breve recurrido histórico del lugar de los otros saberes en la teología práctica/pastoral, el presente artículo hace un análisis de cómo estos saberes se encuentran hoy día en los principales modelos de teología práctica/pastoral, a saber: 1) las teologías prácticas empíricas, más presentes en los países anglosajones, que dialogan mucho con la sicología y la pedagogía; 2) las teologías prácticas críticas, como son las teologías política y de la liberación, que hacen de la praxis la categoría central del quehacer teológico y entran en un diálogo estrecho sobre todo con la sociología, la economía y las ciencias políticas; 3) las teologías prácticas/pastorales fundamentales, propuesta por Browning, que intentan dialogar sobre todo con la filosofía hermenéutica. En un tercer momento, partiendo de tres categorías de la ética de Paul Ricoeur, es decir, la estima de sí, el cuidado el otro y la búsqueda de instituciones justas, el texto propone pensar el quehacer de la teología práctica/ pastoral alrededor de esas categorías, mostrando a qué saberes recurrir. After a brief historical review of the role of other knowledges in practical/pastoral theology, this article analyzes how these knowledges are found today in the main models of practical/pastoral theology, namely: 1) empirical practical theologies, more present in Anglo-Saxon countries, which are often in dialogue with psychology and pedagogy; 2) critical practical theologies, such as political and liberation theologies, which make praxis the central category of the theological task and that are in close dialogue mainly with sociology, economics and political science; 3) fundamental practical/pastoral theologies, proposed by Browning, which attempt to dialogue principally with hermeneutic philosophy. In a third stage, based on Paul Ricoeur's three ethical categories, that is to say, self-esteem, caring for others and the pursuit of just institutions, the text suggests thinking about the practical/pastoral theological task surrounding these categories, presenting which knowledges to resort to.
El carácter práctico de la teología
Geraldo de Mori
Teología y vida , 2010,
Abstract: Este artículo evidencia cómo lo práctico es un elemento eminentemente constitutivo del quehacer teológico. Este aspecto práctico, obvio para la teología -en la tesis del presente estudio-, se presenta como problemático, pues ha dado origen a puntos de entrada tan diversos, que finalmente cuestionan la legitimidad y cientificidad de la teología práctica. This article shows how the practical aspect is a fundamental constituent of the theological endeavor. Such practical aspect, which is obvious for theology as stated in the thesis of this study, is portrayed as being problematic since it has given rise to entry points so diverse that, in the end, they question the legitimacy and scientificity of practical theology.
