A integração da geração fotovoltaica distribuída à matriz elétrica brasileira: uma análise sob a ótica institucional / The integration of the photovoltaic distributed generation on Brazilian electric matrix: an analysis from the institutional perspective

Pavanelli, João Marcos Mott 19 December 2016 (has links)
A matriz brasileira de energia elétrica foi construída historicamente como resultado da confrontação de interesses econômicos, políticos e sociais. Graças a avanços tecnológicos, o setor elétrico brasileiro passa por uma fase de possível inserção de novos modelos, como a geração distribuída de fontes energéticas alternativas, como eólica, biomassa e solar fotovoltaica. Este trabalho oferece uma análise institucional para a compreensão das possibilidades de inserção da geração distribuída fotovoltaica na rede elétrica. Essa análise institucional foi feita através de uma triangulação de técnicas, partindo de revisão bibliográfica de literatura científica, que gerou um modelo analítico para identificar e classificar os principais marcos históricos que direcionaram a estruturação da matriz energética brasileira. Os dados foram confrontados com as entrevistas em profundidade com especialistas do setor elétrico. Os resultados fundamentaram modelos que descrevem a formação histórica de instituições sob os aspectos econômicos, técnicos e normativos. Além disso, os resultados indicam um cenário favorável para investimentos em geração distribuída fotovoltaica até o final da década de 2020, mas também sugerem um possível conflito de equacionamento de custos entre os geradores distribuídos e as concessionárias de distribuição de energia elétrica / The Brazilian electric matrix was built historically as a result of the confrontation among economic, political and social interests. Given the technological advance, the Brazilians electric sector can introduce new models of electric generation, as the distributed generation from alternative energy sources as wind, biomass and photovoltaics. This study offers an institutional analysis to comprehend the perspectives of introducing distributed generation from photovoltaics on Brazilian electric network. This institutional analysis undertook a triangulation of techniques, starting from a literature review, which supported an analysis model. This model was used to identify and classify the main historic marks that constrained the choices concerning the Brazilians electric matrix composition. Historical data was confronted to in-depth interviews with specialists of the Brazilians electric sector. Results supported models which describe the historic formation of institutions under economic, technical and normative aspects. Furthermore the results indicate a favorable scenario to invest in distributed generation from photovoltaic systems in Brazil, at least until 2020, but they also forecast a possible conflict concerning the balance of some costs between the local energys distributor and the owners of distributed generation systems

O ciclo da política nacional de concessão de benefícios tributários (2003-2010) / The national policy cycle of tax breaks concession (2003-2010)

Gonçalves, Maete Pedroso 28 November 2012 (has links)
Essa dissertação pretende mostrar que, na fase de formulação da política nacional de concessão de benefícios tributários, não existem obstáculos impeditivos à imposição da agenda do governo. Essa fase é antes marcada pela discricionariedade do Executivo na apresentação frequente de Medidas Provisórias que criam benefícios tributários. Além disso, o processo não é fechado à participação, pois, durante a tramitação destas proposições no Congresso Nacional, está sujeito à atuação de grupos de interesse privilegiados buscando sua parcela de benefícios distributivos. Por outro lado, existem entraves significativos colocados à fase da implementação das proposições que concedem benefícios tributários. Por ser uma política de difícil acompanhamento, sua execução está sujeita a impasses, negociações e busca de consensos entre setores da burocracia pública e destes com os órgãos de controle externo, o que impõe uma trajetória incremental à fase da implementação, e dificulta a avaliação da eficiência, eficácia e efetividade dos benefícios tributários. Além disso, a política nacional de concessão de benefícios tributários tem características de dependência de trajetória, pois, ao resolver problemas pontuais no varejo, tem se tornado a opção de ação governamental mais viável na ausência de uma reforma tributária abrangente. / This dissertation purpose to show that, at the formulation stage of national tax breaks concession policy, there are no obstacles impending the governments agenda imposition. Rather, this stage is marked by Executives discretion in the frequent presentation of Provisional Measures that create tax breaks. Also, the process is not closed to participation, because during the course of these proposals in Congress, this is liable of privileged interest groups action seeking their portion of distributive benefits. On the other hand, there are significant barriers imposed at the implementation stage of the tax breaks proposals. Because there is a policy of difficult monitoring, its execution is liable to impasses, negotiations and attempts to build consensus among sectors of the public bureaucracy and the latter with external control agencies, compelling an incremental path to the implementation stage, and hampers the evaluation of efficiency, efficacy and effectiveness of tax breaks. Furthermore, the national tax breaks concession policy has path dependence characteristics, because, to solving specific problems at retail, has become the most practicable option of governmental action in the absence of a comprehensive tax reform.

The Failure of Democracy in Iraq / Den Misslyckande Demkoratin i Irak

Al-khalidi, Ali January 2017 (has links)
The motivation of the bachelor thesis is to provide an understanding of democracy in Iraq from 2003 until present. After the fall of Saddam’s regime, there have been general elections but there is still an unstable democracy in Iraq. What are the reasons behind the failure of democracy in Iraq? Of course, there are many reasons behind this but my choice is to focus on three specific ones. How do these three variables that I have chosen, affect the possibility of democracy in Iraq? These two questions will be answered in this bachelor thesis, using Path Dependence Theory and Dahl’s Polyarchy Model and its Criteria that help to analyze and answer the research questions. Iraq has many major problems but the three I have focused on are ethnic and religious divides between Shia and Sunni, the violent environment and the presence of terrorist groups.

Reconceitualizando o Institucionalismo Histórico: path dependence, agencia e mudança institucional / Reconceptualizing the Historical Institutionalism: path dependence, agency and institutional change

Luis Enrique Urtubey de Cesaris 09 October 2009 (has links)
O núcleo desta dissertação é desenvolver um conceito de path dependence mais parcimonioso, coerente e útil, seja teoricamente ou em estudos empíricos. Neste sentido, o insight fundamental é que se partimos de uma conceitualização mais dinâmica, baseada mais em externalidades negativas do que em rendimentos crescentes, o conceito de path dependence pode ser inerentemente mais operacionalizável, robusto e ressoar melhor com a literatura e os estudos Institucionalistas Históricos. O conceito de path dependence pode também ser mais compatível com várias elaborações realizadas dentro do próprio Institucionalismo Histórico sobre questões como mudança institucional, mecanismos explicativos, complementaridade, idéias e agência, e, portanto, enriquecer-se graças aos mesmos. / The objective of this dissertation is to develop a more parsimonious, coherent and useful concept of path dependence, both theoretically and empirically. Its fundamental insight is that with a more dynamic conceptualization, based more in negative externalities than in increasing returns, the concept of path dependence can be inherently more robust and resonate better with the literature and Historical Institutionalist studies. The concept of path dependence can also be more compatible with several theoretical developments which have arisen within Historical Institutionalism regarding questions such as institutional change, social mechanisms, complementarities, ideas, agency and, therefore, to be enriched by them.

No. of bitstreams: 1 Dissertacao_MATHEUS_MULLER.PDF: 1772402 bytes, checksum: dd5b5ed614a44c1db49b70472cbcf63d (MD5) Previous issue date: 2013-03-05 / The proccess of reform of the electricity industry in Brazil followed the global trend over the years 1990 and materialized in line with market principles. The purpose of social, economic and political state went through a long process of restructuring where new regulatory framework was established for the electricity sector. The logic state back to make room for the competitive logic, a kind of return to the origins of the development of the electrical industry, albeit with a conformation organizational and productive much more dense and complex. It is on this background that focuses the study, with the main objective to analyze national policy of restructuring the electricity sector over the decade from 1990 to 2000, from the approach of path dependence. This analytical method is relevant to show that even the innovative initiatives in terms of public policies carry with them elements of structures, institutions and previous policies that act to reinforce actions already initiated. The results point to a policy of power sector reform marked by continue even after the exhaustion of their models. / O processo de reforma da indústria de eletricidade brasileira acompanhou a tendência mundial ao longo dos anos 1990 e se concretizou em consonância com os princípios de mercado. A finalidade social, econômica e política do Estado passou por longo processo de reestruturação, onde novo marco regulatório foi estabelecido para o setor elétrico. A lógica estatal volta a ceder espaço para a lógica competitiva, numa espécie de retorno às origens do processo de desenvolvimento da indústria elétrica, embora com uma conformação organizacional e produtiva muito mais densa e complexa. É sobre esse panorama que se debruça o estudo, com o objetivo principal de analisar a política nacional de reestruturação do setor elétrico ao longo da década de 1990 e 2000, a partir da abordagem da path dependence. Esse método analítico se torna relevante ao demonstrar que, mesmo as iniciativas inovadoras em termos de políticas públicas carregam consigo elementos de estruturas, instituições e políticas anteriores, que atuam de forma a reforçar ações já iniciadas. Os resultados apontam para uma política de reforma do setor elétrico marcada por continuísmos, mesmo após a exaustão do modelo adotado.

Perceptions of intensive forestry and multi-storey wood frames among Swedish actors

Hemström, Kerstin January 2015 (has links)
Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. The results of quantitative and qualitative studies among members of the general public, private forest owners, architects, and contracts managers in Sweden are presented in six different papers. Both intensive forestry and multi-storey wood frames lack sufficient acceptance and compliance with relevant institutions such as priorities, norms, and regulations in the eyes of the studied actors. The acceptance of intensive forestry would be larger among members of the general public if they would perceive such practices to have less negative environmental effects and perceive a greater need to increase forest growth. Among the private forest owners, the interest to cultivate non-native tree species would be larger if there were more positive attitudes towards the economic consequences. Architects and contracts managers associate multistorey wood frames with several disadvantages and uncertainties, primarily with respect to fire safety, stability, durability, and sound proofing. The contracts managers’ perceptions have stronger implications for the prospects for wood frames, than the architects’ perceptions do. Promotional activities aimed to change such perceptions may improve the prospects for more wood framed multi-storey buildings in Sweden. The path dependency of Swedish multi-storey construction however implies that such activities are not enough for multi-storey wood frames to diffuse to greater extent. Broader changes to the wider context of the decisions taken in construction projects, e.g. to policy or economic environments, which change the priorities of the construction industry actors, are needed.

Regionální rozvoj a inspirace z jiných disciplin: Možnosti aplikace konceptů evoluční biologie na vybraná témata regionálního rozvoje

Vaskova, Lucie 19 January 2010 (has links) (PDF)
Le développement régional et l'inspiration puisée dans d'autres disciplines : Les possibilités de l'application des concepts de la biologie évolutionnaire aux sujets sélectionnés du développement régional. - L'application des concepts de la biologie évolutionnaire (BE) à la problématique de la réalité socioéconomique n'est pas un sujet nouveau dans certaines disciplines socioéconomiques, même si cette inspiration pour la problématique de la géographie socioéconomique, ou plutôt du développement régional, est plus récente et en général se fonde sur les applications réalisées notamment en économie. L'objectif principal de cette thèse est d'identifier de nouveaux concepts de la BE et de tenter de les appliquer aux sujets sélectionnés du développement régional dierectement, sans le rôle d'intermédiaire d'autres disciplines. L'attention est dans un premier temps prêtée à la recherche du cadre théorique convenable et d'un aperçu des concepts de la BE déjà appliqués aux sciences sociales. La seconde partie présente certains concepts de la BE pour lesquels les applications potentielles (par l'intermédiaire des analogies et des métaphores) aux thèmes choisis du développement régional ont été identifiées. Les concepts appliqués ont été divisés en quatre ensembles thématiques biologiques plus larges - l'adaptation, la coévolution, la sélection et la spéciation. L'application de la spéciation peut être probablement perçue comme la contribution la plus précieuse de la thèse. Elle s'appuie sur l'hypothèse qu'il est possible d'identifier certains traits analogues entre les concepts socioéconomiques path dependence et lock-in et les concepts de la BE concernant la spéciation et d'identifier et de classifier les mécanismes / structures qui fonctionnent comme des barrières socioéconomiques. Mots-clés : développement régional ; application des concepts de la biologie évolutionnaire ; path dependence

History Matters : How path dependence in the family business influence succession planning - A case study

Liegmann, Michel, Lau, Steven January 2019 (has links)
Background: Family businesses are a complex, overlapping system of business, ownership, and family, which contribute between 70 to 90 percent of the World’s economy. Family businesses do however struggle to survive over generations, to which only 30 percent makes it to the second generation, emphasizing the need for further research within this field, in order to increase the survival rate and positively affect the World’s economy. Purpose: To fill the research gap within succession in family businesses, by investigating the phenomenon of succession planning and how history matters, through the use of the path dependence framework. For this, we are analyzing the second generational Swedish family business, Holtab, which have undergone a conflicted succession in the past and now are planning for the next succession, to which we seek to answer, “How does path dependence influence succession in family businesses?”. Method: Qualitative, single case study with a relativistic ontology and a social constructionism epistemology to showcase how actors construct their realities, which follows an interpretivist philosophy. We follow abductive reasoning with an explorative research strategy to investigate the theory of path dependence, applied to the Swedish family business named Holtab.            Data was collected through in-depth interviews, both semi-structured and unstructured with open-ended questions. Conclusion: Our findings, with the framework of path dependence, clearly show that history matters, as the acknowledgment of it triggered the process of professionalization at Holtab and set a focus for a planned, well-thought succession process, in order to learn and build on the mistakes of the past [history].
