A presente dissertação demonstra aspectos do processo decisório colegiado e propõe um papel para o Conselho Diretor do Instituto Metodista Izabela Hendrix. O trabalho é dividido em uma introdução e três capítulos para demonstrar a caminhada seguida para se chegar às conclusões apresentadas no final. Apresentamos inicialmente, na introdução, os principais paradigmas presentes no processo decisório no Conselho Diretor do Izabela, dentro do contexto da história da educação Metodista. No primeiro capítulo é apresentado a história da educação Metodista, que se confunde com a própria história do Metodismo, desde o seu início na Inglaterra, nos EUA e no Brasil. No segundo capítulo, é apresentado uma abordagem de princípios de processo decisório, enfocando as decisões colegiadas. No terceiro capítulo é abordado a concepção de Conselhos Diretores, apresentando a sua evolução histórica e críticas ao modelo atual e ao processo decisório no Izabela. No capítulo quatro é apresentado a proposta de um papel para o Conselho Diretor do Izabela no atual momento histórico. O papel proposto na conclusão é fundamentado em bases teóricas que norteiam o estudo das decisões colegiadas em Conselhos, a Missão educacional e o modelo organizacional da Igreja Metodista, considerando as suas convicções e o seu desenvolvimento histórico.

o esporte ocupa uma posição privilegiada no segmento de entretenimento e envolve enorme capacidade de geração de renda e de empregos, devendo ser, então, tratado como negócio. Sendo assim, o objetivo do presente estudo é identificar como uma gestão profissional do Departamento de Marketing de um clube de futebol, com um planejamento estratégico bem definido, pode gerar benefícios tangíveis e intangíveis para uma agremiação e, para tanto, vale-se do estudo de caso do modelo de gestão de marketing do Atlético-PR, que vem se constituindo em benchmarking no universo do futebol brasileiro. Desta feita, procura-se demonstrar como o marketing esportivo bem gerido pode incrementar as receitas já tradicionalmente praticadas pelos clubes brasileiros de futebol, a saber: direitos de transmissão, Internet, bilheteria, licenciamento de produtos, publicidade e patrocínio. Para tanto, utiliza-se de um levantamento teórico e empírico da realidade destas fontes de receita, apuradas no estágio atual, e apresenta experiências internacionais e de caráter nacional bem-sucedidas que adaptadas poderiam levar ao aumento dos valores arrecadados pelos clubes brasileiros de futebol. Os resultados indicam que há inúmeras ferramentas de marketing passíveis de aplicabilidade no segmento esportivo, como sugere o estudo de caso do Clube Atlético Paranaense, capazes de fazer com que os clubes brasileiros incrementem seu potencial de receita.

Este trabalho tem por objetivo identificar e analisar as mudanças ocorridas no cenário do federalismo fiscal-tributário brasileiro, no período entre a promulgação da Constituição Federal de 1988 e o encerramento do exercício financeiro de 2000. O referencial teórico está fundamentado na teoria das finanças públicas. Os dados foram obtidos junto a Secretaria da Receita Federal, a Secretaria do Tesouro Nacional e ao Instituto Brasileiro de Geografia e Estatística. Os resultados apontam para uma reversão parcial do padrão de descentralização observado no triênio posterior a promulgação da Constituição de 1988. As disponibilidades da União foram parcialmente reconstituídas, com ênfase nas receitas vinculadas ao financiamento da seguridade social. No âmbito subnacional os estados perderam participação relativa na distribuição das disponibilidades tributárias e os municípios afirmaram a posição obtida no ordenamento constitucional de 1988.

This study aimed to focus on aspects of public administration concerning the implementation of the public policy of complementary blood collection by the itinerant and scheduled PPCCIPS services either trough off local unity or mobile unit blood collection operations, which are managed by the State Institute of Hematology Arthur de Siqueira Cavalcanti - HEMORIO. The case study method was used in that public health institutional field, in search for a better understanding of responsibilities and management related to collection, serology, fractionation, storage and distribution of blood supply to almost all public hospitals and clinics, summed up to agreements with the single health system of the State of Rio de Janeiro. Bibliographic references, documentary and field data obtained through interviews and systematic observation in the public servants of HEMORIO workplaces, were treated by the analysis of the content method and the results of this research revealed the complexity of those services, and needs in outstanding aspects of infrastructure, equipment, logistics and personnel, which are critical for the achievement of the increased public collection of blood in the Rio de Janeiro State, endorsing the suggestions for the implementation of PPCCIPS in HEMORIO. The main point found in this research results concern the immanent ethical commitment of that public service personnel, including staff members and low ranking members as well, perceived due to a brief philosophical overlook on that personnel¿s attitudes. An important strategic aspect was revealed by the need for excellence of midia communications and education programs to implement the community involvement in the whole process. Final reflections point out that personnel posture is considered vital for the quality of the expected care of the technical activities and also for the quality of its final products release to the local public, fluminense, which is the irreplaceable human blood, and their derivatives. Despite the author¿s effort in this dissertation there is much more to be studied on that crucial theme.

O objetivo desta tese é analisar a aplicação da Teoria das Opções Reais (TOR) como método para avaliação de projetos de investimentos em prestação de serviços de Tecnologia da Informação (TI), comparando seus conceitos e características, com o método tradicional do cálculo do Valor Presente Líquido (VPL). O estudo apresenta os conceitos básicos, e ilustra através de exemplo numérico, o método de avaliação da TOR aplicado a projetos de prestação de serviços de TI, analisando criticamente suas características, vantagens e limitações. Por meio desta tese, pretende-se mostrar que a Teoria das Opções Reais é uma alternativa mais adequada do que o método do VPL como método de avaliação de projetos de investimentos em serviços de Tecnologia da Informação, integrando estratégia e finanças, ao considerar as opções de flexibilidade operacionais - adiar, expandir, contrair, abandonar, etc. - e o posicionamento estratégico da empresa, ao longo da vida útil do projeto de investimento; opções estas, que não são devidamente tratadas pelo método tradicional do VPL.

The objective of this study is to identify how a health institution can minimize the emotional impacts caused by the change of a style of classic management for a participative administration, that the workers and controllers can see the institution as a dynamic organization, that must be faced as an alive system, mobile and adaptable, where they is beings that have the right to react and to answer to the stimulatons. For that, the institution can handle motivator¿s instruments that develop in the people the potential to react of adequate way to the changes proposals, as well as increasing the perspective of possible technological improvements and interpersonal relationship between the internal and external customers. To change the style to manage, to hear the staff of support and user, are not part of the routine of the heads that develop classic management. This decision demands adaptation and flexibility, study, update and psychological preparation, to face common feelings to the new. It fits to the new directors, to visualize these feelings and work to minimize, avoiding future upheavals and the confrontation of situations that can harm the production of the company, as well as the quality of the communication between the diverse dimensions of the organization people. In this study case, based in phenomenological methodology, was possible to verify, through half-open interviews and comments, how was faced the feelings caused at the old direction time, composed for military who withheld the power and determined the actions of the hospital in study, was replaced by health professionals, that saw in the work team the best option to solve the problems and the potential to carry through an administration based in adequate strategies the reality of the moment, with the objective of reaching the satisfaction of the customer. Through this work, is possible to prove the theory that the changes cause impacts that affect the behavior of the people involved and cause stress, as well as conclude that despite the new direction show themselves, during the change, much made use to make right and involve all the workers, didn¿t have traced strategies to minimize the emotional impacts caused by the changes, what made all face their feelings of doubts and anxiety without no special care. Many obtained, by themselves, to face and to adapt the new proposals, but some could not assimilate the new administrative methodology and had been moved away definitively from the institution.

According to Bourdieu (1994), there are social camps where the economic logic works upside down. Therefore, the expression ¿family business¿ is paradoxical because inside it resides two distinct and, sometimes, antagonistic logics: the business logic, whose goal is the profit, and the family logic, which aims at the common welfare. That is why one must consider the symbolical exchanges influences on the social relations more than in any other kind of company. Based on these concepts, this research presents an overview of the small and medium brazilian family business universe.

There is a intensity change within financial services industry: deregulation, technology, joint ventures and, in Brazil, privatization, increase of foreign competitors and fall of industry participating from 31 per cent to 5,4 per cent in Brazilian GDP.In this context financial institutions are working very hard to improve their market share, besides promoting customer retention and creating customer loyalty.In this paper we are presenting the scenario of industry in the 90's, opportunity to use segmentation and relationship strategies used by banks through distribution channels.The purpose of this study is to examine the relationship between customer satisfaction and segmentation. To ascertain whether such a link exists, a primary study of 3.378 individuals was conducted in two branches at Rio de Janeiro in March 2001. The results suggest that there is little relationship between customer satisfaction and segmentation, besides other qualitative findings.

The Rational Agent model have been a foundational basis for theoretical models such as Economics, Management Science, Artificial Intelligence and Game Theory, mainly by the ¿maximization under constraints¿ principle, e.g. the ¿Expected Utility Models¿, among them, the Subjective Expected Utility (SEU) Theory, from Savage, placed as most influence player over theoretical models we¿ve seen nowadays, even though many other developments have been done, indeed also in non-expected utility theories field. Having the ¿full rationality¿ assumption, going for a less idealistic sight ¿bounded rationality¿ of Simon, or for classical anomalies studies, such as the ¿heuristics and bias¿ analysis by Kahneman e Tversky, ¿Prospect Theory¿ also by Kahneman & Tversky, or Thaler¿s Anomalies, and many others, what we can see now is that Rational Agent Model is a ¿Management by Exceptions¿ example, as for each new anomalies¿s presentation, in sequence, a ¿problem solving¿ development is needed. This work is a theoretical essay, which tries to understand: 1) The rational model as a ¿set of exceptions¿; 2) The actual situation unfeasibility, since once an anomalie is identified, we need it¿s specific solution developed, and since the number of anomalies increases every year, making strongly difficult to manage rational model; 3) That behaviors judged as ¿irrationals¿ or deviated, by the Rational Model, are truly not; 4) That¿s the right moment to emerge a Theory including mental processes used in decision making; and 5) The presentation of an alternative model, based on some cognitive and experimental psychology analysis, such as conscious and uncounscious processes, cognition, intuition, analogy-making, abstract roles, and others. Finally, we present conclusions and future research, that claims for deeper studies in this work¿s themes, for mathematical modelling, and studies about a rational analysis and cognitive models possible integration. .

The discussion about corporate obligations toward the various stakeholders began in the postindustrial era and developed to culminate in the creation of rules, regulations, programs and projects focusing on the dissemination and promotion of what we know today as corporate social responsibility (CSR). In this context, satisfying this new demand and adopting social policies emerge as a determining factor in defining organizational strategies. Nevertheless, some questions are raised when we examine the subject, such as: To what extent should organizations intervene in society? Is the decision for the organizations to adopt a socially responsible attitude really linked to promoting social well being, or is it only a commercial strategy? How does social marketing relate to CSR projects? The study herein, based on the concept and understanding of CSR theories, stakeholders and social marketing, has sought to find evidence of this relationship, in the light of the Global Compact (GC). It was decided to use the multi-case study methodology, considering the possibility of explaining the reasons why the decisions were taken, how they were implemented and what was the outcome. Interviews, supported by previously prepared scripts, were held with CSR managers, employees from other areas of the organizations, and specialists on the subject. Complementary research studies were made in various sources, such as the website of companies under analysis, their sustainability reports, and the GC websites in Brazil and the United Nations (UN). The results obtained show that the organizations have worked increasingly with CSR projects, but the efforts have not been focused. Special mention is given to the programs that create major impact on the company¿s image and reputation, such as projects competing for prizes and participating in the formation of rankings or socially responsible organizations. From the view of Carroll¿s Pyramid (1991) for CSR, it is found that the projects are predominantly focusing on ethical and philanthropic issues. The driving power of the GC, action based on learning, dialogue and partnership, is not to be found. This factor contributes to the statement that social marketing tools are used to build an ethical and socially responsible image, in detriment to effective action by the organizations to meet the social requirements of their stakeholders. The social marketing has as an objective to transform the way a specific public sees a social question and promotes behavior changes, but what has been seen is the use of marketing tools exclusively to promote the company's image.

The choice of accounting standards capable of defining the recognition, measurement and publicizing of financial and economic information to the general public constitutes one of the accounting community¿s greatest challenges. So, the analysis of the Fundamental Principles of Accounting and of the Conceptual Structure of Accounting becomes relevant because of its direct relation to the normative process and because it represents the essence of doctrines and theories relating to the Science of Accounting. Each country¿s set of rules diverges when it comes to creating and evidencing Accounting Statements, and that¿s why the harmonization of the International Accounting Rules is becoming more important among accountants: as an answer to the world qualitative and quantitative demand for information. When managers, answering a great variety of incentives, manipulate or manage the disclosure of accounting information, they show that the management of accounting information begins to represent a purposeful intervention in the process of elaboration of financial and economic statements with the intention of obtaining some private benefit. In this context, Accounting Regulation performs an important function in the technical procedure of professionals in the area and in the development of practices convergent with international standards, which, in their turn, are already in force. The present study, which is exploratory and non-experimental, aims at presenting and analyzing the process of accounting regulation under the perspective of rules and of the choice of accounting practices as an answer by regulated entities on a tridimensional perspective. The establishment of interaction among diverse fields, through interdisciplinarity, aims at bridging the gap between the fields of law and accounting by articulating concepts and cognitive schemes in a process of mutual enrichment. The research concludes that it is possible to apply concepts from Miguel Reale¿s Tridimensional Theory of Law in the study of accounting regulation.
