Fatores críticos relativos à abertura do setor de transporte de petróleo e derivados

Em decorrência do atual processo de transformação da indústria do petróleo no Brasil, iniciado com base na Nova Lei do Petróleo - Lei n° 9.478, de 6 de agosto de 1997, assim como da respectiva abertura do mercado nacional, que poderá se consolidar a partir do ano 2001, são esperadas mudanças na estrutura da cadeia petrolífera brasileira. Tais modificações deverão ser causadas pelo aumento da concorrência, como conseqüência da entrada de novos agentes no setor, bem como entre o produto nacional e o importado, caracterizando um novo cenário de cunho competitivo no mercado de derivados de petróleo. Desta forma, a importação e exportação de petróleo e seus derivados por novos agentes, associado com a movimentação destes produtos e a utilização da infra-estrutura existente para transporte e armazenagem, são questões que merecem análises e considerações, sob a ótica da regulação. Dentro deste processo em curso, é fundamental a avaliação do grau da regulação, uma vez que os mercados legais, estruturados para a competição, atuam dentro de um contexto de regras preestabelecidas e que economias de mercado totalmente desregulamentadas podem acarretar sérias desigualdades para a sociedade. Esta dissertação tem por objetivo analisar quais são os principais fatores críticos, de cunho administrativo e econômico, que devem ser considerados na abertura do setor de transporte de petróleo e seus derivados a outros agentes, de modo a se obter uma efetiva transição para uma economia orientada pelo mercado, dentro do novo modelo de Estado Regulador. Trata-se de uma pesquisa explicativa, por explicitar tais fatores críticos, assim como exploratória, pois é realizada em área onde existe pouco conhecimento e experiência disponível no País, bem como bibliográfica e documental, uma vez que se apoia na consulta a leis, decretos, portarias, documentos de órgãos públicos, livros, artigos etc. O processo de investigação consiste no levantamento da evolução histórica do setor, até o momento atual, na pesquisa da legislação e regulamentação em vigor, dos princípios da teoria da regulação e da experiência internacional, na análise descritiva do setor de transportes nacional, limitando-se ao transporte marítimo e dutoviário de petróleo e derivados, efetuando uma análise crítica do setor frente à Lei 9.478/97 e a abertura do mercado. O estudo identifica os fatores críticos que permitem criar as condições para o estabelecimento de um mercado orientado pela competição, ou seja, a existência de elementos básicos como oferta, demanda, acessibilidade aos serviços pela sociedade, qualidade e segurança, informação sobre preço e utilização dos produtos ou serviços e adequada fiscalização pelo Estado. Tais fatores estão associados ao acesso a informações, ao controle de tarifas, ao estabelecimento de condições de entrada e saída do mercado, ao controle da qualidade dos serviços prestados e à criação de um ambiente de transição de um regime controlado para um regime de mercado competitivo.

Adoção de novos modelos de precificação em telecomunicações : estudo exploratório sobre os direcionadores e barreiras no mercado brasileiro

O mercado brasileiro de Telecomunicações e Tecnologia da Informação (TIC) tem importância significativa para o desenvolvimento do Brasil, haja vista a evolução do mercado de telefonia móvel, que cresceu 600% nos últimos dez anos. A indústria de telecomunicações, que representa 4,7 % do PIB brasileiro (TELEBRASIL, 2013), passou a ter uma nova dinâmica a partir da elaboração da Lei Geral de Telecomunicações em 1997 e, posteriormente, com a privatização do setor. Esta rápida transformação da cadeia de valor do setor foi também impulsionada pela evolução das tecnologias e de novas arquiteturas de redes. Ademais, a utilização de tecnologias digitais, como aplicativos/APPs e a própria internet, tornou a cadeia de telecomunicações mais complexa, possibilitando o surgimento de novos atores e o desenvolvimento de novos serviços, modelos de negócios e precificação (SCHAPIRO e VARIAN, 2003). Este estudo tem como objetivo analisar os direcionadores e barreiras na adoção de novos modelos de precificação de serviços no mercado brasileiro de telecomunicações, considerando a transformação e evolução do setor. O estudo foi elaborado por meio de uma estratégia de pesquisa qualitativo-exploratória e construtivista baseando-se na abordagem Multinível (POZZEBON e DINIZ, 2012), que trabalha o contexto, o processo e as interações entre os grupos sociais relevantes. A partir desta análise, foi possível compreender os critérios, direcionadores e barreiras no processo de adoção de novos modelos de precificação, as quais destacam-se as demandas dos usuários, a alta concorrência e a necessidade de aumento do retorno do investimento como os direcionadores mais relevantes, enquanto que a qualidade das redes, a falta de sistemas, a situação financeira das operadoras, a complexidade da regulamentação e o surgimento de grupos sociais distintos dentro da empresa são apontados como as barreiras mais críticas neste processo. Dentro deste contexto, os modelos de precificação emergentes abrangem o empacotamento de serviços, ofertas por tempo limitado, modelos de patrocínio/gratuidade, em conjunto com exploração de novas áreas de negócios. Este estudo proporciona uma contribuição prática e acadêmica na medida em que permite uma melhor compreensão do dinamismo do mercado e suporte para as áreas de marketing estratégico e tático das operadoras, bem como na formulação de políticas e regulamentação do setor.

O gerenciamento de impressões e a qualidade dos serviços nos hotéis da Paraíba

The present study has got as its aim to show how the impressions management is being used by the hotels in Paraiba State. For that, the dramma or role play perspective has been adopted as a model for service management. From the theater metaphor, the physical environment and its components can be seen as a scenery of the service show. We conduct the reader to notice the importance of the consummer about the service quality demand and its influence on his satisfaction. A methodology with exploring and qualifying nature has been adopted by using the analyses of content technique in interviews applied to hotel managers lebeled as having 4 and 5 stars in the State, trying to check how impression management takes place, identifying impression management tools used in relation to the physical evidences and to contacting people, as well as checking managers views in the survey about the use of impression management for client satisfaction make. The information revealed that managers, maybe for being unaware about impression management theory, haven t considered neither the physical evidences yet, nor contacting people as marketing tools. About the physical evidences, we could see that hotels take actions in a pulverized way referring to environment decoration and colors, however there isn t a global usage of physical evidences to highlight the service. Contacting people by their turn, receive better importance and attention. It was possible to make sure that managers are aware about the influence of the employee over the attendance quality. This way, we may come into a conclusion that impression management at Paraiba hotels has been under used, as long as managers seem to be, most times, turned to actions related to contacting people, not having realized the planning importance and national-wide use of service scenery in a genaral way yet

Análise de qualidade da atenção à criança na estratégia saúde da família: o óbito infantil evitável como referência

Alma-Ata declaration bring the Primary Attention to the Health (PAH) as first level of health attention for individuals, family and community, which considers infant group as priority. Several initiatives that gave bases to integral attention to the children health formalized in the principles of Unique Health System. Family Health Strategy (FHS) comes to strengthen this attention, instituting new ways of work organization and professional practices that gave impact in their quality indicators. One of them is children mortality, showing decline in their values. Though, studies indicates persistence of avoidable infant deaths. In Natal RN, this reality is also perceptible leading to inquietudes, mainly at the space of services production, it means, which motivated the accomplishment of the present study intending to analyse the way that the organizational and structural processes as long as the professional practices in FHS interfered in the quality of children s health attention who died by avoidable death in the year of 2007 in municipal district of Natal-RN. It treats, therefore, to an exploratory and descriptive survey of cases study type, thar had as primary sources the oficial documents of MH, the family prontuary, pregnant card, child card and testimony obt ined from instrument of research elaborated based in investigation form of infant death by MH, applied to 10 mothers of children who had avoidable death. In analysis it was appealed silmultaneous triangulation of methods and sources, allowing a bigger aproximation from obtained informations. To elucidate the cases, the aspects studied were analyzed to the light of explicative model of Social Determinants of Health. Among individual and family aspects were highlighted the related to age, schooling, family habits and customs and mother s economic condition, besides of pregnancy age, newborn weight and associated diseases, which don t differ from literature about the theme. Reffering to the factors organizational and structural processes and professionals practice, highlihgted, the treatment given by the professionals, the territorialization and adscription of areas, the difficulty of having access to the services or sleepers and the reference and counterreference. But also, the ausence or few greet, the lack of communication, few assiduity and ponctuality by professionals in service, among others. In a general way mothers considers the attendance received in the hospital good and very good , opnions that in the Basic Attention weren t so favorable, in spite of many of predictible actions in this level have been performed in the studied cases. It is observed, therefore, that the social determinants of health has a strong influence in ocurrence of infant deaths, what implicates in a large actuation by Infant Mortality Committee from municipal district. This way, it becomes fundamental the reflection and evaluation about the effectiveness and execution by the processes of vigilance to health in FHUs; the rethink about the social determinants of health in a wide and articulate way to the services quality, to permanent education, to management in service, to the given attention and to the way how it is installed the popular participation and social control. To the professionals it is presented the great challenge to review their daily practice, their values, behaviors and commitment, which ones must be guided by logical of sharing, work in team, humanescence and alterity, not only by the accomplishment of a professional duty

Avaliação da saúde bucal na atenção básica: a perspectiva do usuário

Nowadays, the basic attention in health works according to the Health Family Program (HFP), which is responsible for the organization of the health services with view to provide an appropriate attendance to the needs of the population. Its expansion is expressive in whole country and, the oral health, included in this process, has been seen as a possibility of change the health practices centered in the disease. In face of this perspective, the proposal of study is to discover possible changes in the health care model of oral health in a district, made possible through the perception, evaluation and degree of satisfaction of the user s health service. To reach such objectives, the district of Macaíba in the State of Rio Grande do Norte, was chosen for operational subjects, such as time of implantation of HFP and great covering of this program. The current research used interviews structured with objectives and subjectives questions and questionnaires of socioeconomic characterization addressed to two hundred and seventy (270) individuals (ninety users of an Urban PSF, ninety of a Rural PSF and ninety of an unit non PSF). The analysis of the data was accomplished through the software SPSS/99, that made possible a statistical and analytic appreciation. The HFP units and non HFP units has shown to sort the common odontology problems of the community, and this didn't establish a direct relationship with the general satisfaction. On the other hands, the programmed consultation is related with lager satisfaction of the users. The access form to the odontology treatment of the Units, the satisfaction with the attendance rendered by the dentist and the equip, enough dentists for the community and the social class of the user were decisive for the general satisfaction with the service of oral health. On the other hand, variables as age and education, resolution of the problem and physical conditions of the unit didn't influence the general satisfaction. In spite of the progresses in the implantation of the oral health in ESF, preventive activities, visits at home, access and social participation still reproduce the traditional model of attendance, showing a primary change process

Uma plataforma de integração de middleware para computação ubíqua

One of the current challenges of Ubiquitous Computing is the development of complex applications, those are more than simple alarms triggered by sensors or simple systems to configure the environment according to user preferences. Those applications are hard to develop since they are composed by services provided by different middleware and it is needed to know the peculiarities of each of them, mainly the communication and context models. This thesis presents OpenCOPI, a platform which integrates various services providers, including context provision middleware. It provides an unified ontology-based context model, as well as an environment that enable easy development of ubiquitous applications via the definition of semantic workflows that contains the abstract description of the application. Those semantic workflows are converted into concrete workflows, called execution plans. An execution plan consists of a workflow instance containing activities that are automated by a set of Web services. OpenCOPI supports the automatic Web service selection and composition, enabling the use of services provided by distinct middleware in an independent and transparent way. Moreover, this platform also supports execution adaptation in case of service failures, user mobility and degradation of services quality. The validation of OpenCOPI is performed through the development of case studies, specifically applications of the oil industry. In addition, this work evaluates the overhead introduced by OpenCOPI and compares it with the provided benefits, and the efficiency of OpenCOPI s selection and adaptation mechanism

Chronological Monte Carlo-based assessment of distribution system reliability

Regulatory authorities in many countries, in order to maintain an acceptable balance between appropriate customer service qualities and costs, are introducing a performance-based regulation. These regulations impose penalties, and in some cases rewards, which introduce a component of financial risk to an electric power utility due to the uncertainty associated with preserving a specific level of system reliability. In Brazil, for instance, one of the reliability indices receiving special attention by the utilities is the Maximum Continuous Interruption Duration per customer (MCID). This paper describes a chronological Monte Carlo simulation approach to evaluate probability distributions of reliability indices, including the MCID, and the corresponding penalties. In order to get the desired efficiency, modern computational techniques are used for modeling (UML -Unified Modeling Language) as well as for programming (Object- Oriented Programming). Case studies on a simple distribution network and on real Brazilian distribution systems are presented and discussed. © Copyright KTH 2006.

How Porous are the Walls that Separate Us?: Transformative Service-Learning, Women’s Incarceration, and the Unsettled Self

In this article, we refine a politics of thinking from the margins by exploring a pedagogical model that advances transformative notions of service learning as social justice teaching. Drawing on a recent course we taught involving both incarcerated women and traditional college students, we contend that when communication among differentiated and stratified parties occurs, one possible result is not just a view of the other but also a transformation of the self and other. More specifically, we suggest that an engaged feminist praxis of teaching incarcerated women together with college students helps illuminate the porous nature of fixed markers that purport to reveal our identities (e.g., race and gender), to emplace our bodies (e.g., within institutions, prison gates, and walls), and to specify our locations (e.g., cultural, geographic, socialeconomic). One crucial theoretical insight our work makes clear is that the model of social justice teaching to which we aspired necessitates re-conceptualizing ourselves as students and professors whose subjectivities are necessarily relational and emergent.
