Avaliação das teorias da liquidação ineficiente, monitoramento e risco moral no Brasil

O presente trabalho busca ir além da decisão, capital próprio ou terceiro, e verificar a decisão de qual tipo de recurso terceiro angariar, portanto, analisa a composição do endividamento da empresa com relação à fonte de financiamento: recursos privados ou públicos. Logo, foram construídos modelos econométricos com o intuito de investigar quais características, por parte da empresa, são relevantes na escolha de qual fonte recorrer para financiar suas atividades. Foram utilizados dados em painel de empresas brasileiras não pertencentes ao setor de Finanças e Seguros, cujas ações são negociadas na Bolsa de Valores de São Paulo (BOVESPA). Neste trabalho foram investigadas variáveis das empresas referentes à qualidade e credibilidade das informações contábeis, total de ativos imobilizados, lucratividade, alavancagem, setor de atuação, tamanho da empresa e internacionalização. Os resultados indicaram que fatores como total de ativos imobilizados, alavancagem, lucratividade e alguns setores de atuação são relevantes para determinar a estratégia de financiamento da firma. A variável nível de disclosure, responsável por diferenciar a empresa que possui qualidade da informação contábil superior às demais, não apresentou ser significante, embora, com o sinal esperado. Portanto, os resultados sugerem que as empresas estudadas tendem a seguir a teoria da liquidação ineficiente quando tomam as suas decisões de financiamento.

Um sistema de metas como ferramenta de gestão pública: "O Programa de Metas da Cidade de São Paulo 2013-2016" sob a perspectiva de seus implementadores

This work, developed within the Master's Degree Program in Public Administration and Government of Eaesp-FGV, consists of an exploratory study on performance measurement in the public sector. It is focused on the identification of complexity elements embedded in the implementation of public policies, to which the goals and targets of a target-oriented system relate, and especially on the implementation of this system as a management tool itself, from the case study of the then ongoing "Programa de Metas da Cidade de São Paulo 2013-2016". All information was obtained from municipal managers, in Government Departments responsible for strategic support activities to the implementation of the system, and sectoral Government Departments whose scope also included crosscutting actions, through interviews conducted from a starting question, and then followed by the free talk of the respondents. Through discourse analysis, an assortment of information was conducted, concerning to: 1) the impacts on management, articulation, and governance of the use of performance measurement and result-oriented management; 2) the flow and publicity of information on performance, produced within the monitoring process of this given target-oriented system, and also concerning the use given to this information; 3) the recording and register of experiences and learning related to the Programa de Metas, and its potential to result as a legacy for the public administrative structure of the City of São Paulo. Assuming that the stories managers tell, in this field of Applied Social Sciences, are as valid as Science or the theoretical constructs on the subject, all information gathered from the point of view of the interviewed public officials was segmented and problematized under the light of the literature on performance measurement. The main objective of this research is to contribute to the creation of parameters for qualitative analysis of the information generated in the implementation of a target-oriented system in Public Management at the local level. It is, from then on, expected that these parameters may help managers and researchers on the monitoring and evaluation of performance of a given government, by favoring the translation of merely arithmetic data on percentage of fulfillment of specific commitments, into eloquent elements more enabled to express the evolution of a mandate. Keywords: result-oriented system, Programa de Metas, management for results, performance measurement, government planning, public policy evaluation, monitoring, implementation, transparency, information legacy.

O novo federalismo social e o Rio: desenho de programas complementares de transferência de renda condicionada

Brazilian public policy entered in the so-called new social federalism through its conditional cash transfers. States and municipalities can operate together through the nationwide platform of the Bolsa Familia Program (BFP), complementing federal actions with local innovations. The state and the city of Rio de Janeiro have created programs named, respectively, Renda Melhor (RM) and Família Carioca (FC). These programs make use of the operational structure of the BFP, which facilitates locating beneficiaries, issuing cards, synchronizing payment dates and access passwords and introducing new conditionalities. The payment system of the two programs complements the estimated permanent household income up to the poverty line established, giving more to those who have less. Similar income complementation system was subsequently adopted in the BFP and the Chilean Ingreso Ético Familiar, which also follow the principle of estimation of income used in the FC and in the RM. Instead of using the declared income, the value of the Rio cash transfers are set using the extensive collection of information obtained from the Single Registry of Social Programs (Cadastro Único): physical configuration of housing, access to public services, education and work conditions for all family members, presence of vulnerable groups, disabilities, pregnant or lactating women, children and benefits from other official transfers such as the BFP. With this multitude of assets and limitations, the permanent income of each individual is estimated. The basic benefit is defined by the poverty gap and priority is given to the poorest. These subnational programs use international benchmarks as a neutral ground between different government levels and mandates. Their poverty line is the highest of the first millennium goal of the United Nations (UN): US$ 2 per person per day adjusted for the cost of living. The other poverty line of the UN, US$ 1.25, was implicitly adopted as the national extreme poverty line in 2011. The exchange of methodologies between federal entities has happened both ways. The FC began with the 575,000 individuals living in the city of Rio de Janeiro who were on the payroll of the BFP. Its system of impact evaluation benefited from bi-monthly standardized examinations. In the educational conditionalities, the two programs reward students' progress, a potential advantage for those who most need to advance. The municipal program requires greater school attendance than that of the BFP and the presence of students’ parents at the bimonthly meetings held on Saturdays. Students must achieve a grade of 8 or improve at least 20% in each exam to receive a bi-monthly premium of R$50. In early childhood, priority is given to the poor children in the program Single Administrative Register (CadÚnico) to enroll in kindergarten, preschools and complementary activities. The state program reaches more than one million people with a payment system similar to the municipal one. Moreover, it innovates in that it transfers awards given to high school students to savings accounts. The prize increases and is paid to the student, who can withdraw up to 30% annually. The total can reach R$3,800 per low-income student. The State and the city rewarded already education professionals according to student performance, now completing the chain of demand incentives on poor students and their parents. Increased performance is higher among beneficiaries and the presence of their guardians at meetings is twice compared to non beneficiaries; The Houston program, also focuses on aligning the incentives to teachers, parents and students. In general, the plan is to explore strategic complementarities, where the whole is greater than the sum of its parts. The objective is to stimulate, through targets and incentives, synergies between social actors (teachers, parents, students), between areas (education, assistance, work) and different levels of government. The cited programs sum their efforts and divide labor so as to multiply interactions and make a difference in the lives of the poor.

O acesso aos serviços de saúde por emigrantes brasileiros nos Estados Unidos

A análise do atual contexto político e econômico existente nos EUA, que envolve o acesso e utilização de serviços de saúde pelos imigrantes, diz respeito aos mais de 20 milhões de indivíduos estrangeiros que residem naquele país e não possuem seguro de saúde. Essa população corresponde a 43,8% de 46 milhões de pessoas que não possuem cobertura de provedores privados de saúde nos EUA, sendo 10,5 milhões residentes sem a documentação exigida para viver no País. Para explorar as necessidades, o acesso e a utilização dos serviços de saúde americanos pelos emigrantes de Governador Valadares, MG, Brasil, o presente estudo entrevistou uma amostra de 14 emigrantes valadarenses selecionada por meio da técnica bola de neve. Foram elaboradas questões relacionadas à documentação, local de residência, profissões exercidas, necessidade, acesso e utilização de serviços de saúde. As informações recolhidas junto aos emigrantes residentes nos Estados de Massachusetts e Connecticut permitem afirmar a viabilidade do acesso e da utilização dos serviços de saúde subsidiados pelos governos federal e estaduais e de organizações não governamentais.

Aplicação de classificadores Bayesianos e regressão logística na análise de desempenho dos alunos de graduação

Este trabalho minera as informações coletadas no processo de vestibular entre 2009 e 2012 para o curso de graduação de administração de empresas da FGV-EAESP, para estimar classificadores capazes de calcular a probabilidade de um novo aluno ter bom desempenho. O processo de KDD (Knowledge Discovery in Database) desenvolvido por Fayyad et al. (1996a) é a base da metodologia adotada e os classificadores serão estimados utilizando duas ferramentas matemáticas. A primeira é a regressão logística, muito usada por instituições financeiras para avaliar se um cliente será capaz de honrar com seus pagamentos e a segunda é a rede Bayesiana, proveniente do campo de inteligência artificial. Este estudo mostre que os dois modelos possuem o mesmo poder discriminatório, gerando resultados semelhantes. Além disso, as informações que influenciam a probabilidade de o aluno ter bom desempenho são a sua idade no ano de ingresso, a quantidade de vezes que ele prestou vestibular da FGV/EAESP antes de ser aprovado, a região do Brasil de onde é proveniente e as notas das provas de matemática fase 01 e fase 02, inglês, ciências humanas e redação. Aparentemente o grau de formação dos pais e o grau de decisão do aluno em estudar na FGV/EAESP não influenciam nessa probabilidade.

Divergência entre prática e recomendações para modelos de atuação do PMO : o caso de uma empresa de grande porte do setor industrial

Neste trabalho, o objetivo é identificar, a partir da análise de um estudo de caso, quais são as principais divergências encontradas quando se compara o que a teoria preconiza como o escopo e a abordagem dos Project Management Offices - PMOs e o que acontece na prática, no que diz respeito à real atuação destas estruturas. O tema pode ser considerado relevante devido ao fato de fornecer uma melhor compreensão sobre como as estruturas de PMO realmente atuam, principalmente no que diz respeito ao escopo, isto é, se o PMO é um Programa-Projeto, um PMO Departamental ou um PMO Corporativo e relativamente a sua amplitude, ou seja, se sua atuação é operacional, tática ou estratégica. Para este estudo foi utilizada a metodologia qualitativa, por meio da abordagem de estudo de caso. Foi selecionada uma empresa de grande porte do setor de manufatura não estruturada por projeto para avaliação. A empresa do estudo de caso possui uma estrutura organizacional complexa que possibilita um estudo abrangente. A atuação dos PMOs do estudo de caso foi discutida à luz da revisão de literatura e levando-se em conta, também, as informações colhidas a partir da observação participante. Os resultados deste trabalho permitem concluir que o pressuposto defendido, que é a existência de divergências entre o que a teoria preconiza como escopo e abordagem do PMO e a real atuação dos PMOs, foi confirmado através do estudo de caso; além disso, não existe relação de causalidade clara entre o escopo de atuação dos PMOs e sua posição hierárquica dentro da empresa; e não existe uma atuação padrão destas estruturas, quando comparadas às funções que elas exercem. Por fim, são apresentadas recomendações relativas ao estudo de caso realizado, ou seja, é importante realizar um estudo multicasos entre ao menos uma empresa não estruturada por projeto e outra estruturada por projeto e comparar a atuação dos seus PMOs para melhor compreensão do tema, incluir mais stakeholders no grupo de entrevistados dentro do estudo de caso, realizar um survey com várias empresas de vários segmentos dentro do território nacional e um possível estudo onde seja verificado se tipologias diferentes de estruturas organizacionais podem afetar a atuação práticas dos PMOs.

Facebook3d

INTRODUCTION With the advent of Web 2.0, social networking websites like Facebook, MySpace and LinkedIn have become hugely popular. According to (Nilsen, 2009), social networking websites have global1 figures of almost 250 millions unique users among the top five2, with the time people spend on those networks increasing 63% between 2007 and 2008. Facebook alone saw a massive growth of 566% in number of minutes in the same period of time. Furthermore their appeal is clear, they enable users to easily form persistent networks of friends with whom they can interact and share content. Users then use those networks to keep in touch with their current friends and to reconnect with old friends. However, online social network services have rapidly evolved into highly complex systems which contain a large amount of personally salient information derived from large networks of friends. Since that information varies from simple links to music, photos and videos, users not only have to deal with the huge amount of data generated by them and their friends but also with the fact that it‟s composed of many different media forms. Users are presented with increasing challenges, especially as the number of friends on Facebook rises. An example of a problem is when a user performs a simple task like finding a specific friend in a group of 100 or more friends. In that case he would most likely have to go through several pages and make several clicks till he finds the one he is looking for. Another example is a user with more than 100 friends in which his friends make a status update or another action per day, resulting in 10 updates per hour to keep up. That is plausible, especially since the change in direction of Facebook to rival with Twitter, by encouraging users to update their status as they do on Twitter. As a result, to better present the web of information connected to a user the use of better visualizations is essential. The visualizations used nowadays on social networking sites haven‟t gone through major changes during their lifetimes. They have added more functionality and gave more tools to their users, but still the core of their visualization hasn‟t changed. The information is still presented in a flat way in lists/groups of text and images which can‟t show the extra connections pieces of information. Those extra connections can give new meaning and insights to the user, allowing him to more easily see if that content is important to him and the information related to it. However showing extra connections of information but still allowing the user to easily navigate through it and get the needed information with a quick glance is difficult. The use of color coding, clusters and shapes becomes then essential to attain that objective. But taking into consideration the advances in computer hardware in the last decade and the software platforms available today, there is the opportunity to take advantage of 3D. That opportunity comes in because we are at a phase were the hardware and the software available is ready for the use of 3D in the web. With the use of the extra dimension brought by 3D, visualizations can be constructed to show the content and its related information to the user at the same screen and in a clear way. Also it would allow a great deal of interactivity. Another opportunity to create better information‟s visualization presents itself in the form of the open APIs, specifically the ones made available by the social networking sites. Those APIs allow any developers to create their own applications or sites taking advantage of the huge amount of information there is on those networks. Specifically to this case, they open the door for the creation of new social network visualizations. Nevertheless, the third dimension is by itself not enough to create a better interface for a social networking website, there are some challenges to overcome. One of those challenges is to make the user understand what the system is doing during the interaction with the user. Even though that is important in 2D visualizations, it becomes essential in 3D due to the extra dimension. To overcome that challenge it‟s necessary the use of the principles of animations defined by the artists at Walt Disney Studios (Johnston, et al., 1995). By applying those principles in the development of the interface, the actions of the system in response to the user inputs became clear and understandable. Furthermore, a user study needs to be performed so the users‟ main goals and motivations, while navigating the social network, are revealed. Their goals and motivations are important in the construction of an interface that reflects the user expectations for the interface, but also helps in the development of appropriate metaphors. Those metaphors have an important role in the interface, because if correctly chosen they help the user understand the elements of the interface instead of making him memorize it. The last challenge is the use of 3D visualization on the web, since there have been several attempts to bring 3D into it, mainly with the various versions of VRML which were destined to failure due to the hardware limitations at the time. However, in the last couple of years there has been a movement to make the necessary tools to finally allow developers to use 3D in a useful way, using X3D or OpenGL but especially flash. This thesis argues that there is a need for a better social network visualization that shows all the dimensions of the information connected to the user and that allows him to move through it. But there are several characteristics the new visualization has to possess in order for it to present a real gain in usability to Facebook‟s users. The first quality is to have the friends at the core of its design, and the second to make use of the metaphor of circles of friends to separate users in groups taking into consideration the order of friendship. To achieve that several methods have to be used, from the use of 3D to get an extra dimension for presenting relevant information, to the use of direct manipulation to make the interface comprehensible, predictable and controllable. Moreover animation has to be use to make all the action on the screen perceptible to the user. Additionally, with the opportunity given by the 3D enabled hardware, the flash platform, through the use of the flash engine Papervision3D and the Facebook platform, all is in place to make the visualization possible. But even though it‟s all in place, there are challenges to overcome like making the system actions in 3D understandable to the user and creating correct metaphors that would allow the user to understand the information and options available to him. This thesis document is divided in six chapters, with Chapter 2 reviewing the literature relevant to the work described in this thesis. In Chapter 3 the design stage that resulted in the application presented in this thesis is described. In Chapter 4, the development stage, describing the architecture and the components that compose the application. In Chapter 5 the usability test process is explained and the results obtained through it are presented and analyzed. To finish, Chapter 6 presents the conclusions that were arrived in this thesis.

Multilayer optimization in radio resource allocation for the packet transmission in wireless networks

In the last decade mobile wireless communications have witnessed an explosive growth in the user’s penetration rate and their widespread deployment around the globe. It is expected that this tendency will continue to increase with the convergence of fixed Internet wired networks with mobile ones and with the evolution to the full IP architecture paradigm. Therefore mobile wireless communications will be of paramount importance on the development of the information society of the near future. In particular a research topic of particular relevance in telecommunications nowadays is related to the design and implementation of mobile communication systems of 4th generation. 4G networks will be characterized by the support of multiple radio access technologies in a core network fully compliant with the Internet Protocol (all IP paradigm). Such networks will sustain the stringent quality of service (QoS) requirements and the expected high data rates from the type of multimedia applications to be available in the near future. The approach followed in the design and implementation of the mobile wireless networks of current generation (2G and 3G) has been the stratification of the architecture into a communication protocol model composed by a set of layers, in which each one encompasses some set of functionalities. In such protocol layered model, communications is only allowed between adjacent layers and through specific interface service points. This modular concept eases the implementation of new functionalities as the behaviour of each layer in the protocol stack is not affected by the others. However, the fact that lower layers in the protocol stack model do not utilize information available from upper layers, and vice versa, downgrades the performance achieved. This is particularly relevant if multiple antenna systems, in a MIMO (Multiple Input Multiple Output) configuration, are implemented. MIMO schemes introduce another degree of freedom for radio resource allocation: the space domain. Contrary to the time and frequency domains, radio resources mapped into the spatial domain cannot be assumed as completely orthogonal, due to the amount of interference resulting from users transmitting in the same frequency sub-channel and/or time slots but in different spatial beams. Therefore, the availability of information regarding the state of radio resources, from lower to upper layers, is of fundamental importance in the prosecution of the levels of QoS expected from those multimedia applications. In order to match applications requirements and the constraints of the mobile radio channel, in the last few years researches have proposed a new paradigm for the layered architecture for communications: the cross-layer design framework. In a general way, the cross-layer design paradigm refers to a protocol design in which the dependence between protocol layers is actively exploited, by breaking out the stringent rules which restrict the communication only between adjacent layers in the original reference model, and allowing direct interaction among different layers of the stack. An efficient management of the set of available radio resources demand for the implementation of efficient and low complexity packet schedulers which prioritize user’s transmissions according to inputs provided from lower as well as upper layers in the protocol stack, fully compliant with the cross-layer design paradigm. Specifically, efficiently designed packet schedulers for 4G networks should result in the maximization of the capacity available, through the consideration of the limitations imposed by the mobile radio channel and comply with the set of QoS requirements from the application layer. IEEE 802.16e standard, also named as Mobile WiMAX, seems to comply with the specifications of 4G mobile networks. The scalable architecture, low cost implementation and high data throughput, enable efficient data multiplexing and low data latency, which are attributes essential to enable broadband data services. Also, the connection oriented approach of Its medium access layer is fully compliant with the quality of service demands from such applications. Therefore, Mobile WiMAX seems to be a promising 4G mobile wireless networks candidate. In this thesis it is proposed the investigation, design and implementation of packet scheduling algorithms for the efficient management of the set of available radio resources, in time, frequency and spatial domains of the Mobile WiMAX networks. The proposed algorithms combine input metrics from physical layer and QoS requirements from upper layers, according to the crosslayer design paradigm. Proposed schedulers are evaluated by means of system level simulations, conducted in a system level simulation platform implementing the physical and medium access control layers of the IEEE802.16e standard.

A organização do processo de projeto de arquitetura no meio profissional: uma análise da produção em escritórios

This paper examines, through case studies, the organization of the production process of architectural projects in architecture offices in the city of Natal, specifically in relation to building projects. The specifics of the design process in architecture, the production of the project in a professional field in Natal, are studied in light of theories of design and its production process. The survey, in its different phases, was conducted between March 2010 and September 2012 and aimed to identify, understand, and analyze comparatively, by mapping the design process, the organization of production of building projects in two offices in Natal, checking as well the relationships of their agents during the process. The project was based on desk research and exploration, adopting, for both, data collection tools such as forms, questionnaires, and interviews. With the specific aim of mapping the design process, we adopted a technique that allows obtaining the information directly from employee agents involved in the production process. The technique consisted of registering information by completing daily, during or at the end of the workday, an individual virtual agenda, in which all agent collaborators described the tasks performed. The data collected allowed for the identification of the organizational structure of the office, its hierarchy, the responsibilities of agents, as well as the tasks performed by them during the two months of monitoring at each office. The research findings were based on analyses of data collected in the two offices and on comparative studies between the results of these analyses. The end result was a diagnostic evaluation that considered the level of organization and elaborated this perspective, as well as proposed solutions aimed at improving both the organization of the process and the relationships between the agents under the lens analyzed

Encalhes de Cetáceos ocorridos no período de 1984 a 2005 no litoral do Rio Grande do Norte, Brasil

Strandings of live or dead aquatic mammals constitute an important instrument to provide information regarding the occurrence, biology and ecology of these species. The aim of this study was to register the stranded species of cetaceans, the frequency and the spatial-temporal distribution of theses strandings during the period of 1984 to 2005, in the coast of Rio Grande do Norte. Data was acquired through the monitoring of strandings in the north, north-west and south coast of RN, and through information obtained from institutions and newspaper archives of the State. A total of 122 strandings of cetaceans were registered along the coast of Rio Grande do Norte. Of the 14 species of cetaceans registered, four species had higher frequencies: Sotalia guianensis (n= 65), Steno bredanensis (n = 6), Globicephala macrorhynchus (n = 6) and Physeter macrocephalus (n = 7). Out of 118 strandings, 93 occurred in the south coast (78.8 %), 23 in the north coast (19.5%) and 2 (1.7%) in the north-west coast of the State. The highest frequency of strandings occurred during the months of August to March and the maximum number of strandings occurred from 2000 onwards, as a consequence of the intense monitoring of the Pequenos Cetáceos Project in Rio Grande do Norte
