This doctoral dissertation investigated the institutional logics of the State. The institutional logic concept adopted was the one of Friedland and colleagues: institutional logics are 'stable constellations of practice', the necessary coupling of substances and material practices that constitutes the institutions’ organizing principles (Friedland et.al., 2014). The State is understood as one of the central institutions of society, composed by two dimensions. One is the bureaucratic dimension, permeated by different ideas about how things should be done in the State. The other is the capitalist dimension, permeated by different ideas about what should be done,i.e., what should be the role of the State. I have chosen a specific type of public organization to explore the logic of the State: the Brazilian independent regulatory agencies (IRAs). IRAs have diffused widely in the past years, and the literature suggests that they represent the 'appropriate model of governance' of the capitalist economy (Levi-Faur, 2005). They changed both how things were done - emphasizing the state's rule-making instruments - and what should be done - focusing on competition promotion and correcting market failures (Majone, 1994). In Brazil, IRAs were part of a broader process of State Reform, and represented an important innovation in terms of organizational design, based on autonomy, and role to be performed, based on competition promotion. However, the process of IRAs’ diffusion was largely impacted by the local context and despite being idealized as purely regulatory, their policies and activities indicate that they do much more than promoting competition. In fact, state policies in general, and regulatory policies in particular, 'are rooted in changing conceptions of what the state is, what it can and should do' (Friedland & Alford, 1991). To assess the institutional logics of the State, this research investigated over 9,000 press releases published by three formal independent regulatory agencies in Brazil between 2002 and 2016. Those press releases cover all the news they released since their creation. Press releases are frequently used by Brazilian IRAs, and they serve as a good proxy of the policies and activities conducted by these agencies. I applied a correlated topic model (CTM) to extract the main themes discussed by the agencies in the past years. Originating from the study areas of natural language processing and machine learning, topic models are probabilistic models that uncover the semantic structure of a collection of documents, or corpus (Blei, 2012; Blei, Ng & Jordan, 2003). Differently from other content analysis techniques, topic models are purely inductive and conform to the ‘relationality’ of meaning assumption of the institutional logics literature (DiMaggio, Nag & Blei, 2013). The results indicated that the logics enacted by independent agencies do not refer only to procedural correctness (Meyer & Hammerschmid, 2006) or democracy (Ocasio, Mauskapf & Steele, 2015). In fact, much of what they do is grounded on broader substantive values, reflecting developmental-, pro-competition- and social-oriented interpretations of the role of the State. Yet, the bureaucratic logic is very pervasive within IRAs: it permeates substantive logics, but also it stands up as a logic of its own. Regulatory agencies enact it more often when they are not able to perform their substantive mission. IRAs re-frame at their discretion the practices of administrative police (standards setting and inspections) and public participation (procedural fairness) during periods of crisis, in order to justify their actions. By doing so, they were able to legitimate their existence, gain a new sense of mission and avoid blame for their actions.

Usuzování s nekonzistentními informacemi / Usuzování s nekonzistentními informacemi

Přenosil, Adam January 2018 (has links)
This thesis studies the extensions of the four-valued Belnap-Dunn logic, called super-Belnap logics, from the point of view of abstract algebraic logic. We describe the global structure of the lattice of super-Belnap logics and show that this lattice can be fully described in terms of classes of finite graphs satisfying some closure conditions. We also introduce a theory of so- called explosive extensions and use it to prove new completeness theorems for super-Belnap logics. A Gentzen-style proof theory for these logics is then developed and used to establish interpolation for many of them. Finally, we also study the expansion of the Belnap-Dunn logic by the truth operator ∆. Keywords: abstract algebraic logic, Belnap-Dunn logic, paraconsistent logic, super-Belnap logics

Orientador: Prof. Dr. Vinícius Cifú Lopes / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Mestrado Profissional em Matemática em Rede Nacional, 2015. / Iniciamos esse trabalho com uma breve introdução histórica para que o leitor tenha uma noção de quando e por que houve interesse em sistematizar os raciocínios lógicos desde Aristóteles até nossos dias. A seguir, apresentamos noções de linguagens, com seus símbolos e regras de formação, sintaxe dos cálculos proposicional e de predicados, funções e operações envolvendo o cálculo de predicados e aplicações (fórmulas matemáticas bem conhecidas). No terceiro capítulo introduzimos o conceito de semântica e apresentamos alguns procedimentos de prova como as tabelas-verdade, tableaux e dedução natural envolvidos nesses sistemas. No quarto capítulo apresentamos a Lógica Modal Alética, demonstrações de teoremas do sistema S5, semântica relacionada com mundos possíveis. Em seguida, apresentamos noções de lógicas modais não aléticas e no sexto capítulo, finalizamos esse trabalho com uma atividade que pode ser aplicada para alunos no Ensino Médio. / We begin this work with a brief historical introduction to when and why there was interest in systematizing logical reasoning since Aristotle until our days. Next, we introduce notions of languages, with its symbols and forming rules, the syntax of propositional and predicate calculi, functions and operations involving the predicate calculus and applications (well known mathematical formulas). In the third chapter we introduce the concept of semantics and present some proof procedures as truth tables, tableaux and natural deduction involved in these systems. In the fourth chapter we present alethic Modal logic, proofs of theorems of the S5 system, and the semantics related to possible worlds. Then, we present notions of non-alethic modal logics. In the sixth chapter, we conclude with an activity that can be applied to high school students.

Considering this context, we present the FOQuE system, developed to perform query expansion in order to retrieve semantically relevant and broad results. Based on fuzzy ontologies, this system is able to obtain approximate results that satisfy user requirements according to expansion parameters defined by the user. The additional answers retrieved by the FOQuE system are classified according to the semantic expansion performed and the relevance to the query, therefore it is possible to improve results that are presented to the user. / Diante da crescente facilidade de acesso a dados de diversas áreas do conhecimento, cada vez mais são necessárias técnicas eficazes para recuperar a informação desejada, visando reduzir respostas irrelevantes e assegurar que resultados relevantes não sejam desprezados. Dentro deste contexto, este trabalho apresenta o sistema FOQuE, desenvolvido para realizar diversos tipos de expansão de consultas com o intuito de recuperar resultados semanticamente relevantes e abrangentes. Baseado em ontologias difusas, este sistema é capaz de obter resultados aproximados que satisfaçam aos requisitos do usuário, de acordo com parâmetros de expansão especificados por ele. As respostas adicionais recuperadas pelo sistema FOQuE são classificadas segundo o tipo de expansão realizada e a relevância para a consulta, melhorando, assim, a forma como os resultados são apresentados ao usuário.

REDUÇÃO PLENA DO DEÔNTICO AO ÔNTICO / DEONTIC TO ONTIC FULL REDUCTION

Lindner, Diogo 06 March 2008 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The current dissertation has as its main objective an exposition and critical analysis of Charles Kielkopf's translation of the Standard Deontic Logic (SDL) into a normal alethic logic, and the resulting construction of a system of deontic logic that captures Kantian fundamental concepts and principles such as the concept of causal necessity and the formulations of the Categorical Imperative concerning Kingdom of Nature and Kingdom of Ends. Since this process results in an interpretation of aspects of the Kantian philosophy, it has been chosen, initially, a presentation in general lines of these concepts and, considering the difficulties regarding the applicability of a translation process between deontic and ontic principles, it was done necessary also an exhibition concerning the problem of the inferential barriers, as well as of his more immediate consequence, i. e., Jörgensen's Dilemma. In a second moment, it was also made a characterization of normal modal systems, deontic ones and alethic ones, as well as of the notions of translation between logics and of Dawson modelling. The final chapter consists of a critical examination of Kielkopf's proposal, which uses Dawson modelling to develop a deontic logic based on the alethic system K1. Such Dawson modelling allows the definition of a deontic modalities in terms of iterated alethic modalities, therefore this model constitutes a way of avoiding the problems regarding inferential barriers. The development of an alternative for attribution of logical status to deontic concepts doesn't constitute, however, in an innovative aspect of this proposal, such aspect can be founded in the use made by Kielkopf of his formal model as a tool for the investigation of philosophical concepts, such as the Kantian concepts already mentioned. / A presente dissertação tem como objetivo uma apresentação da proposta de Charles Kielkopf, de tradução da lógica deôntica standard em uma lógica normal alética e de seus resultados quanto à construção de um sistema de lógica deôntica que capture conceitos e princípios kantianos como necessidade causal e as formulações do Imperativo Categórico acerca do Reino da Natureza e do Reino dos Fins. Uma vez que este processo resulta em uma interpretação de aspectos da filosofia kantiana, optou-se inicialmente por uma apresentação em linhas gerais destas concepções e, tendo em vista as dificuldades referentes a aplicabilidade de um processo de tradução entre princípios deônticos e ônticos, fez-se necessária também uma exposição acerca do problema das barreiras inferenciais, bem como de sua conseqüência mais imediata, a saber, o Dilema de Jörgensen. Num segundo momento, também foi feita uma caracterização dos sistemas modais normais, tanto deônticos quanto aléticos, bem como da noção de tradução entre lógicas e dos modelos de Dawson. O capítulo final consiste justamente num exame crítico da proposta de Kielkopf, o qual faz uso dos modelos de Dawson para desenvolver uma lógica deôntica a partir do sistema lógico K1. Tais modelos de Dawson permitem a definição de uma lógica deôntica em termos de modalidades aléticas iteradas, com o que este modelo constitui-se em uma maneira de evitar os problemas referentes às barreiras inferenciais. O desenvolvimento de uma alternativa para a atribuição de um status lógico a concepções deônticas não constitui, contudo, o aspecto inovador desta proposta, tal aspecto encontra-se justamente na utilização por Kielkopf, de seu modelo formal como uma ferramenta para a investigação de concepções filosóficas, no caso, as concepções kantianas já citadas.

Entre a prática científica e a lógica econômica : estudo sobre as orientações de pesquisadores da UFRGS

Barcelos, Régis Leonardo Gusmão January 2012 (has links)
O objetivo deste estudo foi investigar a legitimidade das atividades relativas à comercialização da ciência através da participação de cientistas em mecanismos de transferência de tecnologia e conhecimento para empresas em uma universidade pública no Brasil. O ponto de partida da pesquisa remete às discussões em torno da relação universidade-empresa, estudadas por distintas perspectivas que ressaltam desde a emergência de novos paradigmas na produção do conhecimento científico, tais como os argumentos da universidade empreendedora, até análises mais críticas, ora sublinhando os efeitos negativos, ora demonstrando a manutenção de fronteiras institucionais entre as duas organizações. A investigação utilizou dois métodos: 1) levantamento da participação de pesquisadores em processos de transferência de tecnologia para a indústria, utilizando dados secundários; e 2) pesquisa qualitativa por meio de entrevistas semiestruturadas, identificando os diferentes tipos de manipulação de lógicas institucionais nas práticas acadêmicas, ora voltadas para a comercialização, ora imersas na ciência pública. Verificou-se elevado crescimento de interações da universidade com a indústria. Entretanto, dois aspectos são ponderados. O primeiro diz respeito à predominância de mecanismos tradicionais de transferência de tecnologia, comparado aos outros tipos de interações. O segundo refere-se ao baixo nível de legitimação de práticas empreendedoras nos casos analisados, visto a defesa da lógica científica sobre a lógica comercial. Para a avaliação da incorporação de novos valores e normas sociais na ciência pública, estabeleceram-se tipologias de orientações científicas: orientação tradicional, orientação tradicional híbrida e orientação empreendedora. A partir dos resultados, conclui-se que o argumento da universidade empreendedora apresenta sérias limitações, visto a baixa legitimidade de novos processos de transferência de tecnologia na amostra analisada. Assim, a difusão de novas práticas científicas orientadas para o maior contato com as demandas econômicas, não necessariamente expressam um processo de institucionalização do empreendedorismo acadêmico, como a incorporação de novos valores, normas e orientações científicas. / The objective of this study was to investigate the legitimacy of the activities related to commercialization of science, through the participation of scientists in mechanisms for transferring technology and knowledge to companies in a public university in Brazil. The starting point of the research refers to the discussions around the relationship between universities and business, studied by different perspectives that highlight since the emergence of new paradigms in the production of scientific knowledge, such as the arguments of the entrepreneurial university, even more critical analysis, sometimes stressing negative effects, sometimes demonstrating the maintenance of institutional boundaries between the two organizations. The research used two methods: 1) raising the participation of researchers in the process of technology transfer to industry, using secondary data and 2) qualitative research using semi-structured interviews, identifying the different types of institutional logics handling academic practices, now focused on marketing, sometimes immersed in public science. There was considerable growth in the university's interactions with industry. However, two aspects are considered. The first concerns the predominance of traditional mechanisms of technology transfer, compared to other types of interactions. The second refers to the low level of legitimation of entrepreneurial practices in the cases analyzed, since the defense of scientific logic on the business logic. To evaluate the incorporation of new values and social norms in public science, settled types of scientific orientations: traditional orientation, hybrid traditional orientation and entrepreneurial orientation. From the results it is concluded that the argument of the entrepreneurial university has serious limitations, as the low legitimacy of new processes of technology transfer in the sample. Thus, the diffusion of new scientific practices oriented more contact with the economic demands, not necessarily express a process of institutionalization of academic entrepreneurship, such as the incorporation of new values, norms and scientific orientations.

Fragmenty intuicionistické logiky, intermediárích logik a substrukturálních logik (vybrané otázky). / Fragments of intuitionistic logic, intermediate logics and substructural logics (selected problems).

Truhlář, Pavel January 2018 (has links)
The abstract of the diploma thesis "Positive Formulas for Some Substructural Logics" by Pavel Truhlar We will examine which distributive substructural logics, as defined in the book of Restall "An Introduction to Substructural Logics" have the same positive fragment with and without the weak excluded middle axiom. The main result of this diploma thesis is that some substructural logics have this property. We repeat the basic notions as described in the Restall's book, especially the consecution, natural deduction, frame semantics, Hilbert system. We will use the soundness and completeness theorems. We also will use the equivalence of natural deduction systems and Hilbert systems. All these important theorems are in the above mentioned Restall's book. We make the proof of our main result in the next part. We will use the semantics of frames, similarly as de Jongh and Zhao in the article "Positive Formulas in Intuitionistic and Minimal Logic". We will define the top model. After, we define the construction which converts a model to the top model. We define for each formula the positive part of it; this is the formula, which behaves the same way on the top models as the original formula. We use Hilbert type calculus to formulate our main theorem. We prove our main result using the deduction theorem for certain...

Rupture organisationnelle et continuité culturelle : une étude de cas - la privatisation d'un hôpital public d'une région centrale de la Chine / Organizational rupture and cultural continuity : a case study - the privatization of a public hospital in the central area of China

Li, Fang 21 October 2015 (has links)
Cette thèse entend montrer l’apport d’une prise en compte des repères culturels locaux dans l’analyse des réactions du personnel d’un hôpital public situé la région centrale de la Chine face aux transformations brutales de son organisation au moment où celui-ci est privatisé. Notre approche anthropologique permet d’approfondir l’analyse des (in)satisfactions et des perplexités exprimées librement par les différents acteurs que nous avons interrogés. L’enquête de terrain montre à la fois l’ampleur des transformations survenues et l’écart existant entre les anticipations initiales des acteurs locaux et les réalités observables un peu plus tard, même si les résultats obtenus témoignent de la réussite économique de cette privatisation. Les nouveaux dirigeants de notre hôpital privatisé se sont efforcés d’introduire de nouvelles formes de management, de nouvelles relations inter-organisationnelles tout en évitant autant que possible de trop dévier des valeurs traditionnelles demeurant partagées au sein de l’environnement social de l’hôpital. Ce souci différencie de la plupart des hôpitaux privés qui, faute d’avoir obtenu l’approbation des communautés locales, à se développer commercialement. La thèse apporte ainsi la contribution dans le champ du management. Elle révèle que la continuité culturelle survit aux transformations du système de propriété, créant obligation aux nouvelles directions post privatisation d’en tenir compte. Certes, au cours de la modernisation et de l’évolution sociale, des réformes sont inévitables. Cependant, les repères culturels antérieurs continuent de fournir aux acteurs un cadre d’interprétation leur permettant de s’orienter dans le contexte en transition. La thèse décrit ces logiques enracinées dans la culture chinoise dont la présence pérenne continue d’influencer les fonctionnements des autres entreprises et industries. Nous espérons que la lecture de notre travail pourra aider les gestionnaires et collaborateurs étrangers à mieux comprendre certains comportements inattendus de leurs partenaires chinois. / This thesis expounds, through an analysis of the practitioners’ reactions when privatization drastically transformed their hospital in Central China, the contribution of taking into consideration local cultural factors in the period of organizational reforms. Adopting anthropological approaches, the author interviewed the participants of the reforms and analyzed their various feelings such as disinclination, satisfaction and perplexity. The author also conducted field surveys demonstrating that while the reforms’ observable reality fell short of the expectation of the participants; its outcome was far-reaching and financially successful. The new leadership of the privatized hospital introduced new forms of management and new inter-organizational relationships, meanwhile, considered local cultural factors and strove very hard to avoid departing from traditional values shared within the environment of Chinese hospitals. It is just because of this consideration that the hospital did better than many other private hospitals whose commercial operations failed to obtain the approval of local communities.This thesis is thus expected to make a contribution to the field of the management science. It reveals that the changes in property systems inevitably involve cultural continuity, and this involvement must be taken into account by the new management personnel in post-privatization. During the great change of society, reforms certainly are inevitable. Cultural references, however, continue to provide a framework of interpretation to the actors of reforms, allowing them to orientate themselves in the context of transition.Furthermore, the author discusses some logics rooted in Chinese traditional culture which continues to influence the operations of many companies and institutions. It is hoped that this thesis could help foreign managers and employees to better understand some unfamiliar behavior of their Chinese counterparts.
