Fleet Dynamics around a Seasonal Regulatory Closure on the Scotian Shelf.

van der Lee, Adam 19 September 2012 (has links)
I investigate aspects of fleet dynamics in a mobile gear, groundfish fishery, on the Scotian Shelf; an area subject to a seasonal area closure. Firstly, the direct impacts of the closure on the redistribution of fishing effort and the resultant catch rates of those “fishing the line” (FTL) were examined. Effort was found to concentrate within 30km of the closure boundary. Two areas of potential FTL strategy were identified, which produced variable catch rate trends. East of the closure, areas of highest catch rate corresponded to areas of greatest effort, while to the west, catch rate was often equalized throughout the region, analogous to the ideal free distribution (IFD). Secondly, two effort distributional models were compared: an IFD-based isodar model and a discrete choice model. The isodar was determined to be the preferred model because of both its consistently superior predictive performance and its greater simplicity.

Parte-se dos pressupostos da teoria da legitimidade, segundo a qual, quando as organizações empresariais adotam ações e sinalizam o engajamento em prol do meio ambiente, obtêm a preferência dos consumidores e dos investidores, que, por exemplo, darão prioridade à aquisição de seus produtos: isso poderá impactar nos seus desempenhos operacional e financeiro. Para alcançar o objetivo desse estudo, foram comparados os desempenhos de dois grupos empresariais: o grupo que elabora o inventário de emissões de GEE por obrigação contratual, pois são empresas participantes do programa brasileiro GHG Protocol, e outro grupo de empresas formado pelas participantes do IBrX-100 da BM&FBovespa. Para mensurar os desempenhos operacional e financeiro, foi utilizado o modelo F_Score de Piotroski (2000). Esse modelo é composto por três indicadores: de rentabilidade (I_RENT); de estrutura de capital e liquidez (I_ECL); e de eficiência operacional (I_EFO). Assim, este estudo se apoia ao pressuposto de que o desempenho financeiro é medido pelos I_RENT e I_ECL; e o desempenho operacional, pelo I_EFO. No que se refere à análise de dados, inicialmente, utilizaram-se os testes de Hausman e de Lagrange, que apontaram a análise de painel no modelo de efeitos aleatórios a mais indicada. Os resultados da análise de painel mostraram que não é possível estabelecer relação entre a adoção dos inventários de emissões de GEE e os desempenhos operacional e financeiro, rejeita-se a hipótese do estudo. Diante desse resultado, sugere-se que pesquisas futuras utilizem outras proxies para a mensuração dos desempenhos operacional e financeiro. Além disso, propõe-se transformar as informações constantes nos inventários de emissões de GEE em uma proxy de desempenho ambiental. / This paper examines the relationship between the adoption of GHG emission inventories and the operational and financial performance of companies. It is based on the presuppositions of the theory of legitimacy that, when business organizations take action and signal engagement for the environment, they gain the preference of consumers and investors, who, for example, will give priority to the acquisition of their Products: this may impact on their operational and financial performance. In order to reach the objective of this study, the performance of two business groups was compared: the group that compiles the inventory of GHG emissions by contractual obligation, since they are companies participating in the Brazilian GHG Protocol program, and another group of companies formed by IBrX- 100 of BM & FBovespa. In order to measure the operational and financial performance, the model F_Score de Piotroski (2000) was used. This model is composed of three indicators: profitability (I_RENT); Capital structure and liquidity (I_ECL); And operational efficiency (I_EFO). Thus, this study is based on the assumption that financial performance is measured by I_RENT and I_ECL; And operational performance, by I_EFO. Regarding the data analysis, initially the Hausman and Lagrange tests were used, which pointed the panel analysis in the random effects model the most indicated. The results of the panel analysis showed that it is not possible to establish a relationship between the adoption of the GHG emissions inventories and the operational and financial performance, the hypothesis of the study is rejected. Given this result, it is suggested that future researches use other proxies for the measurement of operational and financial performance. In addition, it is proposed to transform the information contained in the GHG emissions inventories into an environmental performance proxy.

The scenarios designed of change are directly linked to the continuity of greenhouse gases emission. The modern coffee-growing requires the rational and sustainable use of natural resources and agricultural inputs, being essential to adopt environmentally friendly practices in the realization of cultural practices and conduct of the entire production process. The objective of this study is to inventory the sources and estimating emissions of greenhouse gases in the coffee production process, considering the direct and indirect emissions of the process. The inventory was performed using parameters of the GHG Protocol, Ministry of Science and Technology and the IPCC data. The inventory showed that the main greenhouse gas generated in the coffee corresponded to 2.13 tCO2eq h-1, and the consumption of nitrogen fertilizer (47.5%) and the use of agricultural rectification (30.8%) were the sources of greater contribution for these emissions, followed by the consumption of diesel oil. To carry out the planting operations, annual cultivation and harvest in mechanized coffee culture were issued 465.26 kg CO2 eq ha -1, and the planting were issued 242.58 kg CO2 eq ha -1, accounting for 52.14% of total emissions. The operations carried out in mechanized harvesting, issued 124.3 kg CO2 eq ha-1 contributing 26.72% of total emissions and representing 55.82% of the total issued in operations carried out in the annual cultivation. / RESUMO É grande a preocupação com as questões ambientais, em especial no que se refere à possibilidade de ocorrerem mudanças climáticas drásticas nos próximos anos. Os cenários projetados de mudança estão ligados diretamente à continuidade das emissões de gases de efeito estufa. A cafeicultura moderna exige o uso racional e sustentável dos recursos naturais e insumos agrícolas, sendo fundamental a adoção de práticas ambientalmente corretas na realização dos tratos culturais e condução de todo o processo produtivo. Objetivou-se com o presente estudo inventariar as fontes e estimar as emissões de gases de efeito estufa na produção do café, considerando as emissões diretas e indiretas do processo. O inventário foi realizado utilizando-se parâmetros do GHG Protocol, Ministério da Ciência e Tecnologia e dados do IPCC. O inventário demonstrou que os principais GEE gerados na cafeicultura corresponderam a 2,13 tCO2eq ha-1, sendo que o consumo de adubos nitrogenados (47,5%) e uso de corretivos (30,8%), foram as fontes de maior contribuição para essas emissões, seguidas pelo consumo de óleo diesel. Para a realização das operações do plantio, tratos culturais anuais e colheita na cultura do café de forma mecanizada foram emitidos 465,26 kg CO2 eq ha -1, sendo que no plantio foram emitidos 242,58 kg CO2 eq ha -1, sendo responsáveis por 52,14% das emissões totais. As operações realizadas na colheita mecanizada, emitiram 124,3 kg CO2 eq ha-1 contribuindo com 26,72% do total das emissões e representando 55,82% do total emitido nas operações realizadas nos tratos culturais anuais. Para o escoamento da produção de café da fazenda ao armazém foram emitidos 0,76 kg CO2 eq km -1 e do armazém ao porto 0,99 kg CO2 eq km -1.

Modelování četností pojistných událostí / Claims count modeling in insurance

Škoda, Štěpán January 2013 (has links)
1 Abstract: The present work investigates techniques of insurence ratemaking accor- ding to the claims counts of policyholders on the basis of information contained in policies. At the beginning, we provide a closer examination of the theory of genera- lized linear models, which have wide range of applications in the field of actuarial modeling. The second chapter presents the basic Poisson regression model as well as some particular verification methods. Specifically, deviance and Wald test could be found here and furthermore also important results for residuals. The third chapter contains information on alternative approaches to modeling the claim frequencies and at the end the GEE method, that can be applied in case of panel data, is de- scribed. The numerical study based on real insurace data in last part of this diploma thesis illustrate's previously described techniques which were obtained with the help of statistical software SAS.

Traditional Korean Music in Contemporary Context: A Performance Guide to Gideon Gee Bum Kim's Kangkangsullae

Lee, Hyejin 05 1900 (has links)
Gideon Gee Bum Kim is an internationally-acclaimed contemporary Korean-Canadian composer. Kim has utilized traditional Korean music with Western composition techniques in some of his works. Kim created his own style by incorporating traditional Korean musical elements such as the scale, rhythmic diversity, syncopation, variation, ornamentation, and the progression of melody into a body of music that is otherwise contemporary and Western. The purpose of this study is to develop a performance guide for Gideon Gee Bum Kim's Kangkangsullae for string trio. Kangkangsullae trio is based on Korean historical, cultural and musical influences. I give a detailed historical and cultural background for this work and demonstrate how Kim integrated Western compositional techniques with traditional Korean music. My emphasis is on defining specific characteristics of traditional Korean music which will provide several points toward understanding Kim's compositional style.

[en] DECARBONIZING THE SUPPLY CHAIN IN THE OIL AND GAS SECTOR IN INFRASTRUCTURE PROJECTS / [pt] DESCARBONIZAÇÃO DA CADEIA DE SUPRIMENTOS NO SETOR DE ÓLEO E GÁS EM PROJETOS DE INFRAESTRUTURA

LUCIANA SALVATORE 20 April 2021 (has links)
[pt] Desenvolvimento sustentável e emissões de dióxido carbono têm sido amplamente debatido no setor de óleo e gás, que desenvolve planos para reduzir a emissão deste gás em suas operações. Movimentos nesse sentido são influenciados pelos compromissos assumidos no Acordo de Paris que limita o aumento da temperatura global em até 2 graus Celsius pela redução de emissão de gases de efeito estufa (GEE). Além disso, recentes manifestações de fundos de investimentos para que organizações tenham ações de proteção ao meio ambiente indicam ser necessária a preparação das empresas brasileiras para mapear as emissões de GEE em toda a sua cadeia de valor. É objetivo deste trabalho contribuir para que iniciativas de redução de emissão de GEE sejam incluídas em processos licitatórios de projetos de investimento de capital. O estudo foca em projetos de infraestrutura logística e apoio a áreas industriais, especificamente na execução de serviços de construção e montagem de forma a dar materialidade às iniciativas de sustentabilidade ambiental da área de gestão e implantação de empreendimentos. Lançando mão de um estudo de caso, a documentação referente a quatro oportunidades de contrato de construção e montagem de obras de infraestrutura e de apoio a áreas industriais abertas ao mercado brasileiro foi avaliada à luz de critérios levantados na literatura para identificar iniciativas de redução de emissões de GEE durante a fase de construção. Entrevistas com profissionais experientes em gestão e implantação de empreendimentos desse tipo, observação direta da preparação da documentação para contratação de serviços para dois empreendimentos em fase de projeto e revisão de documentos de arquivo e dados corporativos compuseram o estudo. Esta análise permitiu compreender que algumas iniciativas já são encontradas sob a forma de requisitos contratuais com vistas à eficiência energética, minimização de custos e maximização de produtividade associados ao uso de equipamentos e máquinas emissores de GEE e podem ser amadurecidas no cenário da organização estudada, recomendando-se para isso um guia para incorporação de iniciativas de sustentabilidade ambiental com foco em redução de emissão de GEE aos processos de contratação de serviços de construção e montagem de projetos de infraestrutura logística e de apoio às áreas industriais. / [en] Sustainable development and carbon dioxide emissions have been widely debated in the oil and gas sector, which is developing plans to reduce the emission of this gas in its operations. Movements in this direction are influenced by the commitments made in the Paris Agreement limiting the increase in global temperature by up to 2 degrees Celsius by reducing the emission of greenhouse gases (GHG). Also, recent manifestations of investment funds demanding organizations to take actions to protect the environment, mean a call to prepare Brazilian companies to outline GHG emissions throughout their value chain. The objective of this work is to contribute to the inclusion of initiatives to reduce GHG emissions in bidding processes for capital investment projects. The study focuses on logistics infrastructure and support for industrial areas projects, specifically in the execution of construction and assembly services to give materiality to the environmental sustainability initiatives in management and implementation of projects. Using a case study, the documentation related to four contract opportunities for the construction and assembly of infrastructure and offsite areas available in the Brazilian market was evaluated in the light of criteria raised in the literature to identify initiatives to reduce emissions of GHG during the construction phase. Interviews with experienced professionals in the management and implementation of projects of this type, direct observation of the preparation of the documentation for procurement process for two projects in the design phase, and review of archival documents and corporate data comprised the study. This analysis allowed us to understand that some initiatives are already found in the form of contractual requirements with a view to energy efficiency, minimizing costs, and maximizing productivity associated with the use of GHG-emitting equipment and machines and can be developed in the scenario of the studied organization, recommending to this end, a guide for incorporating environmental sustainability initiatives with a focus on reducing GHG emissions into the processes for procuring construction services and assembling of logistics infrastructure and offsite projects.

The study includes some instruments that make up the reference framework of the International Environmental Law (IEL), including the Agenda 21 and the United Nations Framework Convention on Climate Change, as well as some internal planning documents: the Inventory of Greenhouse Gas Emissions, prepared by CETESB (Companhia de Tecnologia de Saneamento Ambiental - Environmental Sanitation Technology Company), and the Environmental Agenda local Port. The research presents initiatives and best practices of two international ports - Shanghai and Los Angeles - that consolidated a partnership for mitigation and adaptation of anthropogenic GHG emissions. Considering the contributions of these tools, this study provides opportunities for the development of local and regional public policies that lead to the reduction of air emissions and greenhouse gases. / Este trabalho traz uma abordagem sobre os impactos ambientais oriundos das atividades do Porto de Santos, mais especificamente aqueles relacionados às emissões antrópicas de gases de efeito estufa (GEE), considerando a vulnerabilidade socioambiental dos municípios desta zona costeira, como consequência das mudanças climáticas. O estudo contempla alguns instrumentos que compõem o marco referencial do Direito Ambiental Internacional (DAI), dentre eles a Agenda 21 e Convenção Quadro das Mudanças Climáticas, bem como alguns documentos de ordenamento interno: o Inventário de Emissões de Gases de Efeito Estufa, elaborado pela CETESB e a Agenda Ambiental Portuária local. Estão incluídas na pesquisa as iniciativas e boas práticas de portos internacionais ¿ Xangai e Los Angeles ¿ que consolidaram parceria para mitigação e adaptação das emissões antrópicas de GEE. À luz das contribuições dessas ferramentas, esse estudo indica caminhos para a formulação de políticas públicas locais e regionais, que conduzam à redução de emissões atmosféricas e de gases de efeito estufa. Pelo esforço de uma governança local, abre-se a oportunidade de criação de uma agenda de compromissos. Esta agenda, se implementada, poderá fomentar o desenvolvimento de novas práticas de gestão ambiental, considerando-se oportunidades oriundas do panorama atual e incorporando as vocações da região.
