Is there a price puzzle in Brazil? An application of Bias-Corrected Bootstrap

Using data from the United States, Japan, Germany , United Kingdom and France, Sims (1992) found that positive innovations to shortterm interest rates led to sharp, persistent increases in the price level. The result was conÖrmed by other authors and, as a consequence of its non-expectable nature, was given the name "price puzzle" by Eichenbaum (1992). In this paper I investigate the existence of a price puzzle in Brazil using the same type of estimation and benchmark identiÖcation scheme employed by Christiano et al. (2000). In a methodological improvement over these studies, I qualify the results with the construction of bias-corrected bootstrap conÖdence intervals. Even though the data does show the existence of a statistically signiÖcant price puzzle in Brazil, it lasts for only one quarter and is quantitatively immaterial

Análise bibliométrica da produção científica brasileira de RH na década de 1990 - um mapeamento a partir das citações dos artigos publicados no ENANPAD

Neste artigo, é usada análise bibliométrica para entender a influência de autores e instituições na produção acadêmica em Recursos Humanos no Brasil na década de 90, bem como para mapear o comportamento de auto-citações e citações à própria instituição dos autores que produziram no período. O estudo levantou, nos 290 artigos de RH publicados na década de 90 (1991 a 2000) nos anais do Enanpad, a constituição, origem e padrão de interrelação de todas as citações, autores e instituições que publicaram e foram citados na área. No total, analisaram-se os padrões bibliométricos de 5814 citações, que compreendiam 342 autores, advindos de 51 instituições. Os resultados mostram uma área com alto índice de auto-citação e endogenia, e com uma elevada incidência de citação de jornais, revistas e autores estrangeiros e não acadêmicos; revelam também que Maria Tereza Fleury (FEA/USP) foi a acadêmica mais citada; que a USP, UFMG, UFRGS e a FGV-EAESP (nessa ordem) são as instituições com os autores mais citados; que a RAE é o veículo nacional mais referenciado no campo; e que alguns autores e instituições que publicaram no período têm elevada propensão à auto-citação e à consulta predominante a autores de sua própria instituição. O artigo termina oferecendo ao campo sugestões para desenvolvimento e debate, a partir dos seus resultados e sua comparação com trabalhos anteriores analisando a mesma base amostral.

Os impactos dos investimentos estrangeiros diretos na evolução da balança comercial brasileira no período pós-real

The purpose of the present study is to discuss the eventual relationship between foreign direct investment in Brazil and trade balance, considering the period after the beginning of "Plano Real" on 1994, which presented a new currency regime and a new profile of Brazilian macroeconomy. It is important to state that there is a controversial debate around the question, since those investments are seen as positive to receiving countries by some authors and negative by other ones. Those who are favorable, argue that the recent attitude assumed by a lot of companies towards internalization is changing the modus operandi in some markets, providing a much more competitive framework. It is also remarkable - they also mention - the potential advantages brought by these new strategies. On the other hand, some authors defend that it increases the exposure of the country that receives such resources, since the subsidiaries of those companies operate under marketing strategies of profit maximization, considered the competitive environment they face. We will go over these opinions troughout the study, trying also to capture the reasons that usually motivate foreign companies to look for new markets and branches and also the effects on receiving country's Balance of Payments. Besides that point, the approach presented will try to answer if the increase of foreign capital stock in Brazil helps to explain some positive response from the country's trade balance, and more, on Balance of Payments. It is also important to mention that the considered period is extremely representative, mainly when considered the huge amounts involved and the increasing liberalization verified in brazilian's external policies since 1990. There is special concern, troughout the study, to define the pattern of such investments, and more, the impacts that those resources brought to public budget. The present study will focus on official data, published by Central Bank of Brazil, mainly those ones regarding Census of Foreign Capitals, as well as the referable to the evolution of Balance of Payments. Finally, based on statistical procedures, it will be provided multiple regressions on available data that will help the reader to capture the effects of some selected variables, which will bring a much more oriented analysis to the discussion.

Responsabilidade social empresarial no mercado de seguros brasileiro: influências culturais e implicações relacionais

The Brazilian insurance market is the ambience in which this research study takes place in search for a better understanding of how cultural characteristics are related with organizational signs, practices and expectations on social responsibility. The concepts of social responsibility as well as the concept of culture are presented and discussed from different points of view, in accordance with different authors and trough several methodological approaches, in order to establish a coherent theoretical basis for qualitative data analysis. The phenomenological attitude assumed by the researcher in especial dialogues situations during the field research phase added new possibilities of apprehension or emergence of each studied organization self orientation in terms of pre-occupation with social issues intimately related with their insurance activities in the market place. Final reflections show the complexity of the insurance cultural context in the studied Brazilian segment, in which cultural and subcultural national and organizational singularities appear. However leaving space for common values and coherent orientation toward the peculiar understanding of social responsibility as inherent to any insurance company activities, themselves. Last comments point out that future research studies may give additional contribution for the continuity of the discussions initiated in this dissertation, expecting that some changes in the organizational posture and practices may happen, especially those related with risk taking and broad processes of communication with clients and society as a whole.

Um estudo de caso sobre aprendizagem organizacional

Frente às mudanças que estão ocorrendo ao longo dos últimos anos, onde a perspectiva da economia passa da industrial para a do conhecimento, nos defrontamos com um novo cenário onde o capital intelectual do individuo é percebido como fator de fundamental importância para o desenvolvimento e crescimento da organização. No entanto, para que esta evolução ocorra, o conhecimento tácito do individuo precisa ser disseminado e compartilhado com os demais integrantes da organização. A preocupação nas empresas se volta, então, para a elaboração de estratégias que corroborem no aperfeiçoamento de seus processos. Além disso, é preciso, também, gerenciar toda esta dinâmica de construção e desenvolvimento do conhecimento, de maneira adequada e eficaz proporcionando, assim, o surgimento de novos valores e de vantagem competitiva. Inumeros modelos para auxiliar no processo de aprendizagem organizacional foram desenvolvidos por diversos autores e estudiosos, dentre eles destacamos o sistema de lições aprendidas, que é construida a partir de experiências, positivas ou negativas, vivenciadas dentro de um contexto, sob ordenação de padrões culturais próprios, com impacto real e significativo. Baseado em processos e procedimentos estabelecidos pela coordenação de um dos produtos ofertados pela FGV e sua rede de distribuição, este trabalho tem como objetivo analisar, à luz da teoria da gestão do conhecimento e, mais especificamente, da gestão das lições aprendidas, como o gereciamento do conhecimento está sendo efetuado no projeto Melhores Práticas, criado pela referida coordenação. Espera-se, também, entender se as fases da aquisição, do desenvolvimento e da disseminação, neste cenário, estão sendo realizados de forma eficaz e, se os resultados alcançados podem servir como uma base para avaliação do efetivo compartilhamento do conhecimento.

Vantagens e desvantagens do modelo dinâmico de Nelson-Siegel : aplicação ao mercado brasileiro

A modelagem da estrutura a termo da taxa juros tem grande relevância para o mercado financeiro, isso se deve ao fato de ser utilizada na precificação de títulos de crédito e derivativos, ser componente fundamental nas políticas econômicas e auxiliar a criação de estratégias trading. A classe de modelos criada por Nelson-Siegel (1987), foi estendida por diversos autores e atualmente é largamente utilizada por diversos bancos centrais ao redor do mundo. Nesse trabalho utilizaremos a extensão proposta por Diebold e Li (2006) aplicada para o mercado brasileiro, os parâmetros serão calibrados através do Filtro de Kalman e do Filtro de Kalman Estendido, sendo que o último método permitirá estimar com dinamismo os quatros parâmetros do modelo. Como mencionado por Durbin e Koopman (2012), as fórmulas envolvidas no filtro de Kalman e em sua versão estendida não impõe condições de dimensão constante do vetor de observações. Partindo desse conceito, a implementação dos filtros foi feita de forma a possibilitar sua aplicação independentemente do número de observações da curva de juros em cada instante de tempo, dispensando a necessidade de interpolar os dados antes da calibração. Isso ajuda a refletir mais fielmente a realidade do mercado e relaxar as hipóteses assumidas ao interpolar previamente para obter vértices fixos. Também será testada uma nova proposta de adaptação do modelo de Nelson-Siegel, nela o parâmetro de nível será condicionado aos títulos terem vencimento antes ou depois da próxima reunião do Copom. O objetivo é comparar qualidade da predição entre os métodos, pontuando quais são as vantagens e desvantagens encontradas em cada um deles.

Práticas interdisciplinares no ensino superior: a experiência do curso de graduação em administração da UNAMA - Pará

This work addresses the study of interdisciplinarity in higher administration education, a topic of great relevance in the present context, due to guidelines issued by Ministry of Education through the National Curriculum Guidelines -NCGs for undergraduate courses in Management. The attention on the subject emerges from the gained experience of a researcher and teacher working as manager of an undergraduate course in Business Administration who set up interdisciplinarity through interdisciplinary projects in a management course pedagogical project at a private university in State of Pará/Brazil. The work rebuilds and reports experiences, and studies the practice of lecturers involved in those interdisciplinary actions. The study aimed to identify changes in pedagogical practices of teachers involved in the searched interdisciplinary experience. To address the questions that directed the work and achieve proposed objectives, from a qualitative approach, a significant bibliographical and documentary work was conducted on the topic. In the survey carried out on secondary sources such as publications of major authors and scientific papers reporting interdisciplinary experiences in higher administration education, it was found that interdisciplinarity for its ambiguous character is still poorly understood by teachers, and reports on its application in administration teaching are incipient. This study also used data collected from primary sources, from dialogues through interviews with educational fellows - teachers and officers of the institution that served as locus of the research, who had the opportunity to experience the studied interdisciplinary experience. Data were processed and analyzed using content analysis technique. Research results showed that teachers of the institution of research have a good understanding of meaning of interdisciplinarity as a link between disciplines; it was also found substantial evidence of changes in teaching practices and actions of such teachers based on their participation in interdisciplinary projects. Although the experience studied can be considered innovative and challenging, much needs to be done in the course management for achievement of interdisciplinary actions in the course, particularly regarding to the removal of institutional, methodological, psychosocial, epistemological obstacles in operationalizing interdisciplinary practices, with emphasis on the need of a process of continuous and specific training aiming at developing skills for interdisciplinary acting, to the extent that these education professionals do not perceive themselves able to act as interdisciplinary lecturers

Criteria for analysis of the structure of electronic scientific journals

This paper is the result of the Masters dissertation studying the role and history of scientific communication, especially the changes that have occurred after the appearance of electronic communication and computer networks. This study showed that hypertext systems are increasingly being used in the scientific and academic world in the production of electronic journals; this makes it possible for the user to rapidly access information in their area. However, these systems need to be improved to help the user during search and access to information. Both printed journals migrating to electronic media, and the exclusively electronic journals should present the current quality indicators. The attempt was made to discover whether characteristics related to printed journals are being maintained in their electronic counterparts. For this, a prototype model was developed to analyze the structure of electronic scientific journals; it composes 14 criteria expressing aspects of quality for these journals. It includes elements of Website Information Architecture and those already in place in printed scientific journals in order to ensure that basic functions - archiving and dissemination - are maintained in electronic publishing. Each criterion consists of variables, which measure the maintenance of these functions both in the migrating printed journals and the exclusively electronic ones. This prototype model was used to analyze Ciência da Informação On-line and DataGramaZero - Revista de Ciência da Informação. Results indicate that this model is able to find out if the basic functions of archiving and dissemination are being maintained in electronic journals. Therefore, its implementation is justified in electronic journals. The model can help librarians, authors, and users of electronic journals to identify quality journals, and assist editors in developing their projects. The material from the study may be included in the preservice and inservice education of Information Science professionals and to support editors of scientific journals.

Spatial variability of physical attributes of an alfisol under different hillslope curvatures

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Fazer a ponte para a escola de todos(as)

The purpose of this study is to understand what are the matrix elements in which everyday activities of social author/authors, actor/actors and actress/actresses are embedded, in order to carry out the Escola da Ponte s political and pedagogic process (PPP). Thus, the object of this study is to reflect on an experience developed in a public school supported by the Portuguese State within the scenario of institutions that are committed to building up a school of the people by investing in democratization and community participation in their management process. The methodological course of action was targeted at the presuppositions of qualitative research (WOODS, 1999; BURGESS, 1997; MILLS, 1982; OLIVEIRA, 1998; BOGDAN and BIKLEN, 1994; MACEDO, 2000; CASAL, 1996; GEERTZ, 2000), with data collected from random word association (MACHADO and CARVALHO, 2003), the discourse of the interviewed (KAUFMANN, 1996; SILVA, 2006; 2002), observation notes and documents (ELIAS, 1997). Based on a multiple reference and theoretical framework, the investigation revealed elements that are construed as the raw material and pillars supporting the bridge of a school of the people, as well as the self-organization of the school community which emerges as a dimension that binds together all the elements and brings new arrangements into the school dynamics by moving from the individual to the society (DUPUY, 1990). Along this line, the central argument is that in the short and long run the public school quality does not spring from macro educational policies, nor from ephemeral mass-production programs, projects or governmental policies, but from the intent of the professionals working there in becoming authors and characters in the process of building up and carrying out the PPP. The Project has been conceived in the light of the needs and intentionality of the community whose support comes from the participation and social control held by the students families and the community s power to force to action public administration central agencies aiming at having the State fulfill its responsibilities

O processo de invenção de si: um estudo sobre a construção identitária de pedagogas em formação

This work was developed in the course of Pedagogy, Universidade Federal do Rio Grande do Norte. Aims to understand the process of identity construction of teachers and educators in initial training. We started from the idea that such process was made by a complex and interdependent movement, once it was an inventive phenomenon wrought by individuals who are authors and actors of the story of their "real life" (KAUFMANN). This identity is rooted in the trajectories and social biographical experiences (FERREIRA), relationships with the constructed and accumulated knowledge in this route (CHARLOT) and in the developing of a sense of cultural belonging institutionally constructed (Luckmann, Berger). Then, the training involves relationships with knowledge in several instances, considering the effects, in one hand, the historic-social production and, in another hand, from the positions of subject and their biographical itinerary, existential and formative. We used the methodology of the Comprehensive Interview (KAUFMANN; SILVA), associated with a network of theoretical references, empirical and very analytical and interpretive activity. She researcher also relied on the "sensitive listening" (BARBIER), empathic attitude of "listening / seeing" the subject, and the notion of "intellectual artisan" (MILLS). The individual interviews were supplemented by the Focus Group. The approach was multi-referential (ARDOINO; MACEDO), with the intertwining of different perspectives, allowing a more complex configuration and less reductionist. In the analysis and interpretation we located the starting point, genesis of identity whose dynamics is not rigidly determined, but localized in space-time that precedes entry into the initial training. It is the time of concerns, questions and reflections about what you want to be in the future professional life. In sequence, we saw the route, multifaceted process whose the direction is the increasing involvement of individuals with their training. This training is engendered by the relations with the curricular, extracurricular and discursive knowledge, as simultaneous dynamics of self training and socio training. The self training of the individuals, understanding the critical, ethic and authority reading of their own experiences, is also seen as an exercise of shared responsibility, it assumes that the relationship with others meanings and professor mediation. The socio training refers to the collective subject and turns to the historical production and diversified knowledge, and comprehension of the various training instances. Self training and socio training are both objects of negotiation, because they are provocative of new designs, and cultural and identity maps, mobilizing the senses towards new meanings of themselves and the professional reality. It is in this interdependence between what is historically produced and the experiences of the subjects, who we located the arrival, considering it as a radically incomplete process of the professional identity and the building itself.
