Recent developments around the sharing economy bring to the fore questions of governability and broader societal Benefit-and subsequently the need to explore effective means of public governance, from nurturing, on the one hand, to restriction, on the other. As sharing is a predominately urban phenomenon in modern societies, cities around the globe have become both locus of action and central actor in the debates over the nature and organization of the sharing economy. However, cities vary substantially in the interpretation of potential opportunities and challenges, as well as in their governance responses. Building on a qualitative comparative analysis of 16 leading global cities, our findings reveal four framings of the sharing economy: "societal endangerment","societal enhancement", "market disruption", and "ecological Transition". Such framings go hand in hand with patterned governance responses: although there is considerable heterogeneity in the combination of public governance strategies, we find specific configurations of framings and public governance strategies. Our work reflects the political and ethical debates on various economic, social, and moral issues related to the sharing economy, and contrib-utes to a better understanding of the field-level institutional Arrangements-a prerequisite for examining moral behavior of sharing economy organizations.

Corporate governance is a leading factor in organizational performance, financial reporting, and stakeholder satisfaction. The purpose of this multiple case study was to explore strategies that senior managers in the accounting industry implement to enforce corporate governance and improve organizational performance. The conceptual framework for the study was stakeholder theory. The population for this study included 3 senior managers of 3 different organizations in the accounting industry located in western United States. Data were collected through semistructured face-to-face interviews and from review of documented corporate governance strategies. The data analysis consisted of the following steps: compiling the data, disassembling the data, reassembling the data, interpreting the data, and drawing conclusions. Three themes emerged from this study: corporate governance, laws, rules, and regulations; the role of corporate governance in organizational performance; and effective corporate governance strategies. The results of this study may contribute to social change by improving the quality of employees' work lives. With improved quality of employee work life, employers may benefit from higher productivity, and consumers may experience improved services.

Esta tese investiga como as estruturas de governança se delimitam e a alocação de direitos de propriedade ocorre mediante uma oportunidade de captura de valor. A análise aplicada ao sistema agroindustrial (SAG) da carne bovina voltado às exportações para a União Europeia em relação ao SAG-típico (mercado) é utilizada como base empírica. Buscou-se na economia de custos de transação e teoria de direitos de propriedade os elementos para avançar no conceito de sistemas agroindustriais e subsistemas estritamente coordenados (SSEC). Ao teorizar a relação entre a qualidade do ambiente institucional e a tolerância organizacional, esta tese contribui ao avançar com os mecanismos de proteção de direitos de propriedade e ajuda a explicar a eminência dos SSEC. Buscou-se identificar as regularidades observadas dos agentes que atuam nessas transações - ativos específicos investidos, grau de recorrência, grau de conhecimento e capacidade de adaptação - internas e para o mercado externo e compará-las. Esta análise delimita as diferenças institucionais, os agentes coordenadores dos diferentes sistemas estritamente coordenados e as fronteiras de um SAG-típico e um SSEC voltado para as exportações e outro voltado para o mercado interno de qualidade. Por meio de três estudos de casos com as maiores indústrias de processamento brasileiras estudou-se a coordenação com o pecuarista e os sistemas que cada uma delas apresenta. Entre as regularidades dos estudos de caso e contribuições, concluiu-se que a eminência dos SSECs-qualidade para o mercado interno decorre do choque institucional que levou a criação do SSEC-exportador para a EU e o processo de aprendizagem organizacional. Isto permitiu explorar o grau de tolerância organizacional dos arranjos dessas empresas. Agregando a primeira metodologia, a pesquisa quantitativa junto aos pecuaristas foi realizada com o objetivo de validar as variáveis que discriminam os SSECs exportador e da qualidade em relação ao SAG-típico no sistema da carne bovina. / This thesis investigates how governance structure are constituted and property rights allocated when faces a new opportunity to capture value is observed. The research is applied to beef cattle agribusiness system (SAG) coordinated to attend European Union imports contrasting with the typical SAG (Brazilian Market). Based on transaction costs economics and property rights theory elements we advance on SAG and strictly coordinated subsystems (SCSS). Theorizing about the relation institutional environment quality and organizational tolerance. This thesis contributes with the protection mechanisms of property rights and helps to explain the eminence of SCSSs. Searching to identify the regularities observed between agents and compare these transactions (specific assets, recurrence, knowledge, adaptation capacity). This analysis permits to delineate institutional differences, coordinator agents from different SCSSs and their frontiers of a typical SAG x SSEC-exporter to UE or quality. Though three case studies with the major Brazilian processing companies, it was studied the coordination with producers and the systems that each one have. The regularities presented on the case studies and the contributions, it can be concluded that the eminence of SCSS-quality to the internal market was a consequence of the institutional chock that leads the creation of the SCSS to UE and the organizational learning process. This allowed to explore the concept of organizational tolerance of this arrangements. Aggregated to the first methodology, a quantitative research with producers was done to validate the variables that distinguishes the SCSSs -exporter and quality one in relation of the typical in beef cattle system.

In this study, a literature review and qualitative research design are used in an attempt to establish the obstacles to the effective governance of schools in previously disadvantaged communities. From the research, it emerges that the SGBs govern their schools intuitively. This is because they lack knowledge of how schools should be governed. Various strategies to build the governance capacity of these SGBs are formulated in this study to assist them to govern their schools effectively. Effective governance is an important instrument that can restore order, protect the rights of both learners and educators, prevent discipline problems amongst learners and establish the provision of quality education in these communities. / Teacher Education / M.Ed.
