Determinants of corporate capital structure: a comparison of public and private firms

 This thesis investigates how capital structure decisions of private and public firms in the UK differ in regards to their ownership structure, information asymmetry (proxied by audit quality) and access to debt capital.

Essays on decision sciences: exploring cognition, information processing, and complexity

This thesis provides three original contributions to the field of Decision Sciences. The first contribution explores the field of heuristics and biases. New variations of the Cognitive Reflection Test (CRT--a test to measure "the ability or disposition to resist reporting the response that first comes to mind"), are provided. The original CRT (S. Frederick [2005] Journal of Economic Perspectives, v. 19:4, pp.24-42) has items in which the response is immediate--and erroneous. It is shown that by merely varying the numerical parameters of the problems, large deviations in response are found. Not only the final results are affected by the proposed variations, but so is processing fluency. It seems that numbers' magnitudes serve as a cue to activate system-2 type reasoning. The second contribution explores Managerial Algorithmics Theory (M. Moldoveanu [2009] Strategic Management Journal, v. 30, pp. 737-763); an ambitious research program that states that managers display cognitive choices with a "preference towards solving problems of low computational complexity". An empirical test of this hypothesis is conducted, with results showing that this premise is not supported. A number of problems are designed with the intent of testing the predictions from managerial algorithmics against the predictions of cognitive psychology. The results demonstrate (once again) that framing effects profoundly affect choice, and (an original insight) that managers are unable to distinguish computational complexity problem classes. The third contribution explores a new approach to a computationally complex problem in marketing: the shelf space allocation problem (M-H Yang [2001] European Journal of Operational Research, v. 131, pp.107--118). A new representation for a genetic algorithm is developed, and computational experiments demonstrate its feasibility as a practical solution method. These studies lie at the interface of psychology and economics (with bounded rationality and the heuristics and biases programme), psychology, strategy, and computational complexity, and heuristics for computationally hard problems in management science.

Educação para a saúde: um estudo de caso em curso supletivo

A educação para a saúde pretende educar as pessoas no sentido de torná-las capazes de reconhecerem suas necessidades em termos de saúde e, ao mesmo tempo, desenvolver-lhes o sentido de responsabilidade na adoção de atitudes conscientes que contribuam para a promoção e manutenção da saúde individual e coletiva. Programas de educação para a saúde, admitidos também como contribuição para atingir os índices sanitários que caracterizam o bem-estar físico, mental e social das populações, raramente são elaborados e executados pelos órgãos da educação e da saúde. São importantes quando considerados em relação ao desenvolvimento econômico e social e como forma educativa em saúde, através da análise de seus objetivos e conteúdos, decorrentes da aplicação de um projeto. Estudados no sistema escolar, no curso supletivo, e em relação ao currículo utilizado pelas escolas, os resultados demonstraram que programas de educação para a saúde preenchem uma lacuna existente nessa área, inclusive por dos programas curriculares adotados elas instituições oficiais de ensino.

Decision making process: a comparison between the public and private sector

The problem of decision making, its mechanisms and consequences is the very core of management, it is virtually impossible to separate the act of manage from this knowledge area. As defined by Herbert Simon – "decision making" as though it were synonymous with "managing". A decision is a selection made by an individual regarding a choice of a conclusion about a situation. This represents a course of behavior pertaining to what must be done or what must not be done. A decision is the point at which plans, policies and objectives are translated into concrete actions. Our behavior during decisive moments is closely linked with our brain dominance profile. Over the years, our decision-making processes develop a consistent pattern, which can be described as a decision-making style. Our style is grounded in our preferences, which arise from our brain dominance characteristics […]. The importance of understanding the impact of our thinking preferences and how to improve the effectiveness as a leader of organizations are the main justifications for this thesis; the main problem addressed is the behavioral profile diversity in a selective Master’s cohort formed by students from several different countries. The research methodology approach has been quantitative, through questionnaire administration using the HBDI (Herrmann Brain Dominance Instrument), a validated framework developed by William "Ned" Herrmann when he was the leader of General Electric's Crotonville facility. This questionnaire has been administered in hundreds of thousands professional, enabling the possibility to establish correlations between a certain group and several historical databases. The selected group of analysis is the first cohort (23 students) from the CIM (Corporate International Master's), a joint program between Georgetown University (USA), ESADE (Spain) and FGV (Brazil). Besides decision preferences, the obtained profile enables the discussion on leadership style, heuristic's pitfalls and a base to compare with future cohorts. The fundamental research question is: how diverse is the dominant decision-making profile for the CIM students?

Exploring different social media users from the millennials’ generation: a cross-cultural behavioral analysis of brazilian users of Facebook and chinese users of RenRen

With the increasing importance of digital communication and its distinct characteristics, marketing tools and strategies adopted by companies have changed dramatically. Among the many digital marketing tools and new media channels available for marketers, the phenomenon known as social media is one of the most complex and enigmatic. It has a range that still is quite unexplored and deeply transforms the present view on the promotion mix (Mangold & Faulds, 2009). Conversations among users on social media directly affect their perceptions on products, services and brands. But more than that, a wide range of other subjects can also become topics of conversations on social media. Hit songs, sporting events, celebrity news and even natural disasters and politics are topics that often become viral on the web. Thus, companies must grasp that, and in order to become more interesting and relevant, they must take part in these conversations inserting their brands in these online dynamic dialogues. This paper focuses on how these social interactions are manifested in the web in to two distinct cultures, Brazil and China. By understanding the similarities and differences of these cultures, this study helps firms to better adjust its marketing efforts across regions, targeting and positioning themselves, not only geographically and culturally, but also across different web platforms (Facebook and RenRen). By examining how companies should focus their efforts according to each segment in social media, firms can also maximize its results in communication and mitigate risks. The findings suggest that differences in cultural dimensions in these two countries directly affect their virtual social networking behavior in many dimensions (Identity, Presence, Relationships, Reputation, Groups, Conversations and Sharing). Accordingly, marketing efforts must be tailored to each comportment and expectations.

Lei Maria da Penha: avaliação dos seis anos de implantação em Belém/PA

Este estudo constitui a dissertação apresentada no Curso de Mestrado em Serviço Social da UFPA, cujo tema “Lei Maria da Penha: Avaliação dos 06 anos de Implantação em Belém/PA”, analisa a discussão e avaliação da aplicabilidade da Lei nº 11.340/06 (Maria da Penha) para o combate à violência doméstica e familiar no município de Belém/PA. Objetiva também aprofundar o conhecimento sobre a temática da mulher e das relações de gênero. Com essa finalidade, o trabalho foi realizado mediante pesquisa bibliográfica, com a utilização de materiais já publicados como: artigos, livros e os materiais disponíveis na internet e pesquisa exploratória, visando a uma apreensão do problema para melhor compreendê-lo e explicitá-lo. Os instrumentais de coleta de dados foram aplicados junto aos sujeitos sociais envolvidos na problemática, a fim de superar a aparência do fenômeno e apreender a dinamicidade de sua estrutura de forma universal, particular e singular. Considera-se importante pontuar que os seis anos de aplicabilidade da Lei “Maria da Penha” em Belém ainda não surtiu resultados efetivamente satisfatórios, em decorrência da falta de equipamentos públicos destinados ao atendimento desse tipo de violência, pois existe apenas 01 (uma) Delegacia da Mulher e 03 (três) varas de violência doméstica e familiar contra a mulher na capital do Estado e a carência de recursos, financeiros, materiais e pessoais, configurando um quadro ainda deficitário para a implementação integral da Lei. Dessa maneira, embora a Lei tenha proporcionado a possibilidade de proteção e justiça, essa situação ainda não se concretizou de fato em Belém do Pará. Porém, não se pode desconsiderar a importância dessa Lei e as mudanças propostas por ela, com o objetivo de universalizar o acesso à justiça por contingentes da população historicamente excluídos de direitos e principalmente o mérito do reconhecimento da violência doméstica e familiar contra a mulher, em suas diferentes modalidades, como problema público e social, passível de inferência das forças do Estado. Logo, existe uma legislação nacional capaz de reduzir a incidência desse fenômeno, se aplicada de modo consistente e efetivo, com o fortalecimento e ampliação da rede de proteção à mulher vítima de violência, pois o problema é complexo e envolve medidas judiciais, administrativas, legislativas, econômicas, sociais e culturais, sem as quais ficaria inviável realizar um atendimento global ao problema. A Lei n.º 11.340/06 ainda se encontra em fase de experimentação e certamente deverá sofrer vários ajustes, porém é preciso manter o texto em sua integralidade por tempo suficiente para medir o seu impacto, evitando alterações precipitadas que possam desfigurar ou até anular a referida Lei.
