Too big to fail? O fracasso do lobby financeiro na formação das regras para as instituições globais sistemicamente importantes (G-SIBs) / Too big to fail? The failure of financial lobby in the rulemaking to the global systemically important banks (G-SIBS)

Thais Guimarães Junqueira 13 March 2018 (has links)
Consideradas uma das principais medidas das reformas regulatórias financeiras pós-crise 2008, as novas políticas para os bancos \"too big to fail\", também conhecidos como bancos globais sistematicamente importantes (G-SIBs), representam uma grande oportunidade para um melhor entendimento da complexa relação entre Estados Nacionais e os grandes conglomerados financeiros. Dialogando com a ideia -ubíqua na literatura de economia política internacional de finanças - que com frequência identifica na regulamentação financeira transnacional a presença de regulatory capture, este trabalho objetiva verificar, a partir de um estudo empírico, em que medida essas novas regras produzidas em âmbito internacional foram forjadas em prol dos interesses e preferências dos atores privados afetados por tal regulamentação. As opiniões dos representantes do setor bancário privado no processo de consulta para as regras estabelecidas pelo Comitê de Basiléia de Supervisão Bancária (Basel Committe on Banking Supervision) em 2011, sob a epígrafe \"Global Systemically Important Banks: Assessment Methodology and the Loss Absorbency Requirement\" constituíram o material de base para o estudo. O argumento central apresentado neste trabalho é o de que o setor bancário transnacional não foi bem-sucedido em fazer valer seus interesses e preferências na elaboração desta regulamentação, confirmando a tese defendida por Kevin Young (2009;2012; 2013c), de que a influência do setor privado financeiro é assistemática, circunscrita e condicionada. Entre os mecanismos que limitaram a capacidade de influência dos grandes bancos nessa fase regulatória, dois aspectos foram especialmente significativos: a adoção do paradigma macroprudencialista pelos reguladores e o contexto político, principalmente dos países desenvolvidos. / Considered as one of the key measures of the financial regulation overhaul following the 2008 crisis, the new policy towards \"too big to fail\" banks, also known as global systemically important banks (G-SIBs), represents a great opportunity for a better understanding of the complex relationship between national states and major financial conglomerates. Discussing the generally ubiquitous idea in the international political economy literature which often identifies the presence of regulatory capture in transnational financial regulation, this paper aims to verify, based on an empirical study, whether these new international rules have been elaborated according to the interests and preferences of the private actors affected by such regulation. The opinions and views of the private banking sector in the consultation process of the rules established in 2011 by the Basel Committee on Banking Supervision, named \"Global Systemic Important Banks: Assessment Methodology and the Loss Absorbency Requirement\", constituted the base material for this work. The central argument presented in this paper is that the transnational banking sector was not successful in asserting its interests and preferences in the elaboration of this regulation, confirming the thesis sustained by authors such as Kevin Young (2009, 2012; 2013c) claiming that private financial sector influence is limited, conditioned and not systematic. Two aspects have been especially significant among the mechanisms that limited the influence of large banks in this regulatory phase: the macroprudential ideational shift in the international regulatory policy community and the political context, especially in developed countries.

Ideální model resolučního mechanismu pro banky v Evropské unii / Ideal Crisis Management Mechanism for Credit Institutions and Investment Firms in the European Union

Kropjok, Vít January 2021 (has links)
Ideal Crisis Management Mechanism for Credit Institutions and Investment Firms in the European Union Abstract: The 2007-8 financial crisis brought about the most severe economic contraction since the Great Depression. Regulators on both sides of the Atlantic were taken aback and soon realized that they had no tools to deal with distressed banks and other financial services firms, failure of which could undermine financial stability not only within individual states, but also on a global scale. As a result, central banks of in particular the United States and the Eurozone became the most important actors in the fight against the unfolding crisis and de facto the only "governmental agencies" capable of swift and decisive measures. Their timely and vigorous reaction most likely warded off the collapse of the global financial system, though it was not without controversies. These controversies are analyzed in this dissertation in order to find out what role should central bank have during financial crisis. Governments followed central banks with massive bank bailouts. In many countries, governments went beyond liquidity provision and nationalized their banks, which threatened their own solvency. Although the global financial system has been largely restored in the last decade, it has been achieved at huge...

MISSILE FLIGHT SAFETY AND TELEMETRY AT WHITE SANDS MISSILE RANGE

NEWTON, HENRY L. 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Missile Flight Test Safety Managers (MFTSM) and other flight safety personnel at White Sands Missile Range (WSMR) constantly monitor the realtime space position of missile and airborne target vehicles and the telemetered missile and target vehicle performance parameters during the test flight to determine if these are about to leave Range boundaries or if erratic vehicle performance might endanger Range personnel, Range support assets or the nearby civilian population. WSMR flight safety personnel rely on the vehicle telemetry system to observe the Flight Termination System (FTS) parameters. A realtime closed loop that involves the ground command-destruct transmitter, the vehicle command-destruct receiver (CDR), other FTS components, the missile S-band telemetry transmitter, and the ground telemetry acquisition/ demultiplex system is active when the vehicle is in flight. The FTS engineer relies upon telemetry to provide read-back status of the flight termination system aboard the vehicle. WSMR flight safety personnel use the telemetry system to assess realtime airborne vehicle systems performance and advise the MFTSM. The MFTSM uses this information, in conjunction with space position information provided by an Interactive Graphics Display System (IGDS), to make realtime destruct decisions about missiles and targets in flight. This paper will aid the missile or target developer in understanding the type of vehicle performance data and FTS parameters WSMR flight safety personnel are concerned with, in realtime missile test operations.

Made available in DSpace on 2016-04-26T20:20:37Z (GMT). No. of bitstreams: 1 Arthur Davis Floriano Ribeiro.pdf: 594229 bytes, checksum: 71391ff7046243dee607dad557ad327f (MD5) Previous issue date: 2011-11-08 / Based on the concept of freedom, this research examines the contours of the right to freedom, especially freedom it´s relates to thought and other mental processes (freedom of will or freedom of thought in the broad sense), within the legal system assumes Brazilian-criminal. To this end, this work seeks to draw a general view about the subjective aspect of criminal law patriotic, examining the subjective elements of typicality, the antilegal and guilt, as well as the subjective conditions that influence the sentencing, not forgetting, even , to emphasize the Brazilian punitive legal system that preachescriminal justice. This examination, which reviews the changes that occurred throughout the history of Brazilian criminal law, intent, moreover, for theories that relate to the theme of subjectivity in the criminal as well as studies in the field of Psychology Personality of Psychoanalysis and Neurobiology, cast doubt on the freedom during the formation of intention (thought) and at the stage of manifestation (manifestation of thought). Thus, this research seeks to check if, in Brazil, today consolidated subjective structuring, which still has traces of retributive, thins the studies that have been held around the limits of human freedom. For the last, the problems pointed out that the Brazilian system has when it comes to the protection of human freedom, especially freedom of thought, this work assumes the task of providing, as appropriate, elements for a possible overhaul of the system. Without claiming to solve all problems related to this subject, this research aims, in short, bring to debate the problem of freedom in the camp of thinking and acting, so that, if possible, can promote a new reflection on the Brazilian penal law and its legitimacy / Partindo do conceito de liberdade, a presente pesquisa procura examinar os contornos que o direito à liberdade, sobretudo à liberdade que se relaciona ao pensamento e aos demais processos mentais (liberdade da vontade ou liberdade de pensamento em sentido amplo), assume dentro do sistema jurídico-penal brasileiro. Para tanto, o presente trabalho busca traçar um panorama geral acerca do aspecto subjetivo do Direito Penal pátrio, examinando os elementos subjetivos da tipicidade, da antijuridicidade e da culpabilidade, bem como as circunstâncias subjetivas que influem na fixação da pena, não se esquecendo, ainda, de enfatizar o caráter punitivo que predica o sistema jurídico-penal brasileiro. O referido exame, que passa em revista as transformações ocorridas ao longo da história do Direito Penal brasileiro, atenta, outrossim, para as teorias que se relacionam com o tema da subjetividade no âmbito criminal, bem como para os estudos que, no campo da Psicologia da Personalidade, da Neurobiologia e da Psicanálise, colocam em dúvida a liberdade na fase da formação da vontade (pensamento) e na fase da exteriorização (manifestação do pensamento). Assim, a presente pesquisa busca verificar se, no Brasil, a estruturação subjetiva hoje consolidada, que ainda possui os traços da retributividade, se afina aos estudos que têm sido realizados em torno dos limites da liberdade humana. Por derradeiro, apontados os problemas que o sistema brasileiro apresenta no que tange à proteção da liberdade humana, em especial da liberdade de pensamento, o presente trabalho assume a tarefa de fornecer, se o caso, elementos para uma possível reformulação do sistema. Sem ter a pretensão de resolver todos os problemas relacionados à matéria, a presente pesquisa tem por objetivo, em suma, trazer ao debate o problema da liberdade na seara do pensar e do agir, a fim de que, se possível, consiga promover uma nova reflexão acerca do Direito Penal brasileiro e de sua legitimação

Assessing Binary Measurement Systems

Danila, Oana Mihaela January 2012 (has links)
Binary measurement systems (BMS) are widely used in both manufacturing industry and medicine. In industry, a BMS is often used to measure various characteristics of parts and then classify them as pass or fail, according to some quality standards. Good measurement systems are essential both for problem solving (i.e., reducing the rate of defectives) and to protect customers from receiving defective products. As a result, it is desirable to assess the performance of the BMS as well as to separate the effects of the measurement system and the production process on the observed classifications. In medicine, BMSs are known as diagnostic or screening tests, and are used to detect a target condition in subjects, thus classifying them as positive or negative. Assessing the performance of a medical test is essential in quantifying the costs due to misclassification of patients, and in the future prevention of these errors. In both industry and medicine, the most commonly used characteristics to quantify the performance a BMS are the two misclassification rates, defined as the chance of passing a nonconforming (non-diseased) unit, called the consumer's risk (false positive), and the chance of failing a conforming (diseased) unit, called the producer's risk (false negative). In most assessment studies, it is also of interest to estimate the conforming (prevalence) rate, i.e. probability that a randomly selected unit is conforming (diseased). There are two main approaches for assessing the performance of a BMS. Both approaches involve measuring a number of units one or more times with the BMS. The first one, called the "gold standard" approach, requires the use of a gold-standard measurement system that can determine the state of units with no classification errors. When a gold standard does not exist, is too expensive or time-consuming, another option is to repeatedly measure units with the BMS, and then use a latent class approach to estimate the parameters of interest. In industry, for both approaches, the standard sampling plan involves randomly selecting parts from the population of manufactured parts. In this thesis, we focus on a specific context commonly found in the manufacturing industry. First, the BMS under study is nondestructive. Second, the BMS is used for 100% inspection or any kind of systematic inspection of the production yield. In this context, we are likely to have available a large number of previously passed and failed parts. Furthermore, the inspection system typically tracks the number of parts passed and failed; that is, we often have baseline data about the current pass rate, separate from the assessment study. Finally, we assume that during the time of the evaluation, the process is under statistical control and the BMS is stable. Our main goal is to investigate the effect of using sampling plans that involve random selection of parts from the available populations of previously passed and failed parts, i.e. conditional selection, on the estimation procedure and the main characteristics of the estimators. Also, we demonstrate the value of combining the additional information provided by the baseline data with those collected in the assessment study, in improving the overall estimation procedure. We also examine how the availability of baseline data and using a conditional selection sampling plan affect recommendations on the design of the assessment study. In Chapter 2, we give a summary of the existing estimation methods and sampling plans for a BMS assessment study in both industrial and medical settings, that are relevant in our context. In Chapters 3 and 4, we investigate the assessment of a BMS in the case where we assume that the misclassification rates are common for all conforming/nonconforming parts and that repeated measurements on the same part are independent, conditional on the true state of the part, i.e. conditional independence. We call models using these assumptions fixed-effects models. In Chapter 3, we look at the case where a gold standard is available, whereas in Chapter 4, we investigate the "no gold standard" case. In both cases, we show that using a conditional selection plan, along with the baseline information, substantially improves the accuracy and precision of the estimators, compared to the standard sampling plan. In Chapters 5 and 6, we investigate the case where we allow for possible variation in the misclassification rates within conforming and nonconforming parts, by proposing some new random-effects models. These models relax the fixed-effects model assumptions regarding constant misclassification rates and conditional independence. As in the previous chapters, we focus on investigating the effect of using conditional selection and baseline information on the properties of the estimators, and give study design recommendations based on our findings. In Chapter 7, we discuss other potential applications of the conditional selection plan, where the study data are augmented with the baseline information on the pass rate, especially in the context where there are multiple BMSs under investigation.

O estudo justificou-se por acreditar que a eficácia precisa ser considerada como um dos indicadores de uma Educação de Qualidade e que possa promover a equidade. O problema de pesquisa buscou responder às seguintes indagações: como os professores, discentes, pais de estudantes e profissionais que atuam no setor pedagógico do Instituto percebem e explicam os fenômenos da reprovação e da evasão escolar nos cursos de Ensino Médio Integrado à Educação Profissional? Qual o perfil dos estudantes reprovados e evadidos com relação ao gênero no contexto das políticas de ações afirmativas? O estudo compreendeu uma pesquisa com caráter de método misto, na medida em que utilizou uma abordagem que possibilita uma aproximação aos fenômenos sob as diferentes perspectivas. Por fim, uma pesquisa empírica foi realizada por meio da adoção de entrevista semiestruturada. O lócus da pesquisa foi o IFBA - Campus de Barreiras e as residências de alguns estudantes. Os resultados demonstraram: que os índices de reprovação são elevados na primeira série; que o índice de reprovação dos estudantes cotistas é superior comparado aos demais estudantes; que o percentual dos estudantes que concluem o curso, em quatro anos, é baixo na perspectiva de uma escola promotora de eficácia da equidade. No que se refere à percepção dos atores, apontou para um conjunto de fatores ou dimensões envolvidas no processo de aprendizagem, com destaque para os aspectos subjetivos, institucionais e externos ligados às políticas públicas da educação no país, como responsáveis pelo fenômeno da exclusão dos estudantes na Instituição. / ABSTRACT This thesis points out the results of a survey about the phenomenon of evasion as well as the school failure at the Federal Institute of Education, Science and Technology of Bahia / IFBA - Campus of Barreiras, along the period from 2010 to 2014. The study was justified by believing the effectiveness must be considered as one of indicators of a high quality standard of education aiming to promote fairness. The research problem questioned: how teachers, students and their parents and professionals who work in the pedagogical sector of the Institute perceive and explain the phenomena of failure and so the students’ truancy in high school courses integrated to professional education in the context of affirmative political actions? The study involved a search method with mixed character, in which was used an approach that allows a forthcoming view to the phenomena from different perspectives. Finally, an empirical research was carried out by adopting a semi-structured interview. The locus of the research was the Federal Institute of Education - IFBA - Campus from Barreiras and the residences of some students. The results pointed out that: the failure rates are higher in the initial series; the failure rate of quota students is higher compared to other students; the percentage of students who complete the course in four years, is low in the perspective of promoting a standard school effectiveness of equity. Regarding to the perception of the actors, pointed to a set of factors or dimensions involved in the learning process, highlighting subjective, institutional and external aspects, connected to public educational policies in the country, which has been responsible for the exclusion phenomenon of students in the institution.

Neste trabalho foram analisadas séries temporais com falhas das variáveis de temperatura máxima, temperatura mínima, temperatura média, umidade relativa e precipitação e foram usadas as médias mensais do ano de 1990 a 2000, de treze estações do Rio Grande do Sul. Nas séries que estavam completas criaram-se falhas artificiais e aplicaram-se os métodos estatísticos de: análise de regressão múltipla, média simples, Steurer, média de três estações, proporção normal e análise harmônica, a fim de prever os dados faltantes. Após a aplicação de cada método, calculou-se o erro absoluto, o erro quadrático e o erro percentual e avaliou-se o desempenho do método para o preenchimento em cada variável. Nestas análises constatou-se que, dos métodos estudados, os que melhor obtiveram bons resultados para previsão de dados foram os de análise de regressão múltipla, Steurer e média de três estações. / The study of time histories of meteorological observations is an essential background for environmental studies, in particular weather and climate variability predictions. In this work, monthly averages of maximum, minimum and average temperatures, relative humidity and monthly precipitation collected from thirteen meteorological stations in the State of Rio Grande do Sul (Brazil) in the period from 1990 to 2000, were analyzed. Artificial gaps were created in complete series and Multiple Regression, Simple Averages, Steurer, Three Stations Averages, Normal Proportion and Harmonic Analysis methods were applied to fill them. The performance of the methods was evaluated by comparison of absolute, quadratic and percentual computed errors. Best results were obtained with Multiple Regression, Steurer and Three Stations Methods.

O objetivo é conhecer os principais problemas enfrentados pelo CIEP 386 que justifiquem suas elevadas taxas de reprovação e, então, propor ações que possibilitem diminuí-las. Para tal utiliza-se o questionário contextual aplicado aos alunos do 3ª serie do Ensino Médio, quando da realização das provas do SAERJ (Sistema de Avaliação do Estado do Rio deJaneiro) de 2011 e dados administrativos, obtidos diretamente da secretaria da escola. Baseados nos resultados obtidos e na gestão escolar desenvolvida nesta unidade, traça-se um plano de ação educacional constituído por: reforço escolar para Português com o Projeto de Leitura e Produção Textual utilizando a tecnologia, nivelamento curricular e reforço escolar para o ensino de Matemática com jogos matemáticos, aulas práticas para Área de Ciências e suas Tecnologias, criação de um modelo de recuperação paralela, monitoramento dos resultados das avaliações externas e internas, promoção de uma campanha de valorização do espaço escolar visando um maior estímulo ao processo de aprendizagem, atingindo diretamente as principais partes envolvidas: professor e aluno.Todas as ações visam diminuir os índices de reprovação e, consequentemente, elevar a qualidade do ensino. / High rates of failure are a kind of the most problems that high school in Rio de Janeiro has been frequently faced. An important line of study now a days in education is to understand why these this rates are so high. The point of the view of this work is these results and after than the work is to propose actions that can do this rates go down. This project is made in CIEP 386.
