As questões do ambiente e da natureza como um todo, tais como, preservação, conservação de ecossistemas, florestas, rios, descartes de dejetos líquidos, gasosos e sólidos, a colocação de elementos poluentes no solo, ar e água, são temas de extrema e extensa divulgação e discussão na mídia, na academia e na sociedade como um todo. A preocupação da sociedade, sensibilizada e temerosa por esta questão, uma vez que ela própria tornar-se vítima do processo de degradação do ambiente, é cada vez mais latente. Pessoas e empresas, aos poucos, tornam-se mais conscientes de suas necessidades e exigências de participação no processo de degradação e preservação do meio em que vivemos o que faz com que todos observem com profunda atenção, suas atitudes. As empresas, pressionadas pela mídia e pela sociedade e por uma legislação cada vez mais restritiva, veem-se obrigadas a agir cada vez mais de forma precavida, coerente e preocupada em relação ao ambiente. Assim, elas adotam estratégias empresarias frente às questões ambientais sem que, por outro lado, desconsiderem a sua lucratividade e seus ganhos, essenciais numa lógica empresarial, inserida no contexto do modelo econômico capitalista. Essa pesquisa, visa entender, quais passos e normativas legais as empresas de Shopping Center estabelecidas na cidade de Porto Alegre, no Estado do Rio Grande do Sul, mais precisamente o caso do Bourbon Shopping Wallig, necessitou seguir, para a implementação de seu empreendimento. Quais as medidas de mitigação e compensação aos impactos ambientais foram tomadas e baseadas em que normativas ou estudos. A pesquisa visa confirmar, também, se estas medidas tomadas, derivadas de sua implantação no local, desde sua construção - que alterou completamente a paisagem do local - até seus próprios elementos e suas técnicas de construção, seguiram as normas e exigências legais dos instrumentos utilizados para regrar esta obra. Além disso, se avalia quais foram efetivamente seus resultados na prática, analisando no empreendimento após sua conclusão, qual sua eficácia, seus resultados concretos e quais as manifestações que se obtém do mercado, na mídia e da sociedade em geral, frente a esta preocupação e às atitudes consideradas pró-ambientais. / The issues of the environment and nature as a whole, such as preservation, ecosystems conservation, forests , rivers, liquids, gases and solid waste discharges and the placement of polluting elements in the land, air and water are issues of extreme and extensive dissemination and discussion through out the media, at the academy and society as a whole. Because of the population concern about this issue, they are becoming sensitized and fearful about it. They eventually will become victimized by the environmental degradation that has had a latent increase as time goes by. People and companies gradually have become more aware of their participation in the process of environment degradation in which they are living. This is making everyone aware of their attitude towards the environment. Companies have been increasingly pressured by the media and society and more restrictive laws are finding themselves obligated to act very cautious, concerned and consistent about the environment. They are applying business strategies in order to comply with environmental issues without disregarding their profitability and earnings which are essential in the logistic of the capitalist business model. This research aims to understand which steps and legal ways the mall companies and stores established in the town of Porto Alegre , Rio Grande do Sul State, more precisely at the Bourbon Shopping Wallig were needed and followed by this enterprise implementation project. It also aims to understand the mitigation and compensation towards the environmental impact that they have caused, all based upon professional studies. Due to the complete landscape changed during the mall construction, this research also wants to prove if the construction techniques had followed all legal regulations and rules that are required by law. Furthermore , one should consider if the practical results of this enterprise had been achieved after completion. We should also evaluate the efficacy, the real results, media, market manifestations, opinions and in a grand spectrum if the environmental worries had been respected and fulfilled.

This study was developed with the aim of identifying as well as assessing the environmental impacts associated to the construction of Municipal Landfills, according to technical standards. The research is classified as qualitative, carrying out documentary analysis, bibliographic research and data collection. The environmental impacts associated to the main activities related to Municipal Landfills, which were proposed by Sánchez (2008), were evaluated making use of an Interaction Matrix and the Ad hoc method. With the collected data, the activities in the Landfills which represented greater impact potential were identified under the negative aspect, so as to verify, with the use of Interaction Networks, the probable negative chain environmental impacts as well as the proposal of mitigating measures for these impacts. The activity which presented more negative impacts on the environmental compartments was the Implementation of the construction site, followed by the vegetation Removal activity. Both activities are part of the Implementation phase: Preparatory activities for a Landfill, confirming the obtained result in the assessment of environmental impacts in the Interaction Matrix, where this phase presented the greatest possibility of negative environmental impacts on the environmental compartments. For all the probable negative environmental impacts, at least one mitigating measure was selected, and the most recurrent ones were the Implementation of a vegetation curtain, planting of grass and curbs on the slopes, covering the garbage with earth and, the installation of draining systems and waterproof coating. This study works as a tool for the municipal government agents, especially due to the importance of implementing the mitigating measures which were proposed, minding the negative environmental impacts. / Este estudo foi desenvolvido com o objetivo de identificar e avaliar os impactos ambientais associados à construção de Aterros Sanitários Municipais, de conformidade com as normas técnicas. A pesquisa classifica-se como qualitativa, com a realização de análise documental, pesquisa bibliográfica e de levantamento. Foram avaliados os impactos ambientais associados às principais atividades relacionadas a Aterros Sanitários Municipais, propostas por Sánchez (2008), utilizando-se de uma Matriz de Interação e do método Ad hoc . Com os dados gerados, foram identificadas as atividades dos Aterros Sanitários de maior potencial impactante sob o aspecto negativo, para então, com o emprego de Redes de Interação, serem averiguados os prováveis impactos ambientais negativos em cadeia, bem como, propostas medidas mitigadoras a estes impactos. A atividade que mais apresentou impactos de caráter negativo sobre os compartimentos ambientais foi a Implantação do canteiro de obras, seguida da atividade de Remoção da vegetação. Ambas as atividades fazem parte da fase de Implantação: Atividades preparatórias de um Aterro Sanitário, confirmando o resultado obtido na avaliação de impactos ambientais da Matriz de Interação, onde esta fase apresentou a maior possibilidade de impactos ambientais negativos sobre os compartimentos ambientais. Para todos os prováveis impactos ambientais negativos foram elencadas, pelo menos, uma medida mitigadora, sendo que as mais recorrentes foram a Implantação da cortina vegetal, o Plantio de gramíneas e bermas nos taludes, o Recobrimento do lixo com terra e, a Instalação de sistemas de drenagem e manta impermeável. Este estudo serve como ferramenta para os gestores públicos municipais, especialmente pela importância de se implantar as medidas mitigadoras que foram propostas, atendendo aos impactos ambientais negativos.

This dissertation presents a liquidity stress-testing model for evaluating liquidity and systemic risk in banks from developed and emerging economies respectively. The model further relies on simulations to generate liquidity buffer losses for both a non-crisis and crisis period as well. The emerging economy is represented by South Africa (SA) and the developed economy by the United Kingdom (henceforth UK). The Liquidity Stress Tester model (LST) has been successfully applied to both the Dutch and UK markets in previous research. The model's flexibility and adaptability allows it to assess different banking systems and different reactions (buffer restoration and leverage targeting) of participants within these milieus. The LST considers feedback effects arising from bank reactions and allows for the assessment of severely stressed haircuts and systemic risk increases caused by reputation degradation and increased contagion from other banks. Losses stemming from the second round effects of a liquidity event are explored through the reactions conducted by banks in the banking system. The study conducts a review of liquidity risk models utilised in previous research. Characteristics of these models and the data they used are highlighted, shedding light on the advantages and shortcomings of these models. Possible restrictions in liquidity risk management are also explored. The study discusses the relevance of the South African/UK economies' comparison, as well as the selected periods chosen for investigation. To assist further research with the LST, the study illustrates and discusses how it is modelled and developed in Microsoft Office Excel. The results obtained illustrate the potential severity of second round feedback effects of a liquidity event on liquidity positions in banks. The effects of mitigating actions conducted by banking institutions reacting to initial liquidity stress shocks are explored, as well as the way these actions could potentially affect second round effects on banks. The analysis and discussion of simulated results attempts to isolate and identify characteristics of economies and periods used that may have contributed to specific liquidity events. The study concludes with a summary of the research and suggestions for possible future work and development using the LST. / MCom (Risk Management), North-West University, Potchefstroom Campus, 2013

Legalmente, foi implementado pelo Governo Federal, o Programa Nacional de Produção do Biodiesel (PNPB). Entretanto, sua produção gera o glicerol. Para os pesquisadores, caso disposto indevidamente, esse coproduto poderá acarretar problemas ambientais. Assim, se o intuito é alcançar a sustentabilidade com a implantação do biodiesel na matriz energética, tornase relevante sua adequada gestão, uma vez que não há controle sobre sua produção e destinação. Falhas de mercado geralmente coexistem com as chamadas falhas de regulação. Nesse contexto, o objetivo foi analisar alternativas de destinação do glicerol realizadas por produtores de biodiesel que podem contribuir no âmbito das medidas compensatórias e mitigadoras. Os métodos utilizados foram pesquisa bibliográfica, documental e de campo para se estudar a teoria e a prática que envolvem o tema. A análise de conteúdo foi realizada com o uso do software MAXQDA®. Além das unidades estudadas, compostas por grandes e pequenos produtores de biodiesel, foram entrevistados engenheiros químicos e pesquisadores na área. Como resultados tem-se que as alternativas de destinação do glicerol realizadas pelos pequenos produtores estudados parecem evidenciar alocação eficiente de recursos. Assim, dentre os aspectos sustentáveis, o econômico se destaca na forma de oportunidade de negócios e geração de renda para o pequeno produtor. Ao contrário, nos grandes produtores, uma vez que poderá demandar maiores custos de transação a destinação é ineficiente e transferida para terceiros. Assim, buscando perpetuar o sistema econômico e proteger o meio ambiente, espera-se que os resultados possam fornecer subsídios para a implantação de políticas que visem remediar ineficiências relacionadas à preservação ambiental e sustentabilidade nos negócios. / Legally, the Federal Government implemented the National Biodiesel Production Program (PNPB). However, its production generates glycerol. For researchers, if improperly disposed of, this co-product could lead to environmental problems. Thus, if the intention is to achieve sustainability with the implementation of biodiesel in the energy matrix, it becomes relevant its adequate management, since there is no control over its production and destination. Market failures generally coexist with so-called regulatory failures. In this context, the objective was to analyze which alternatives of destination of glycerol carried out by biodiesel producers can contribute in the scope of the compensatory and mitigating measures. The methods used were bibliographic, documentary and field research to study the theory and practice that involve the theme. Content analysis was performed using MAXQDA® software. In addition to the units studied, composed of large and small biodiesel producers, were interviewed chemical engineers and researchers in the area. As a result, the alternatives of destination of the glycerol carried out by the small producers studied seem to show efficient allocation of resources. Thus, among the sustainable aspects, the economic stands out in the form of business opportunity and income generation for the small producer. On the contrary, in large producers, the destination is transferred to third parties, since it may demand higher transaction costs. Thus, a system is proposed to encourage, discipline and facilitate alternatives that may contribute to the perpetuation of the economic system in conjunction with environmental protection, attributing functionality to compensatory and mitigating measures. It is hoped that the results could contribute to the implementation of policies aimed at increasing subsidies, especially for small producers.

Secondary infusions is a common method to deliver short infusions of intravenous (IV) drugs and fluids. Errors associated with this infusion method have led to patient safety concerns. This study's objective was to empirically evaluate interventions to mitigate secondary infusion risks. Three interventions, including a technology-based intervention (clamp detector on a smart pump), a training-based intervention (educational module), and a practice-based intervention (use of a separate pump for short infusions), were tested in a simulated inpatient unit. The technology-based intervention significantly decreased secondary clamp errors whereas the training-based intervention reduced complex pressure differential errors. The practice-based intervention was the only intervention that significantly decreased both secondary clamp errors and pressure differential errors, but introduced new risks due to mismanagement of residual volume in IV tubing. Study results highlight the need for a combination of mitigation strategies and can help guide the selection of interventions to reduce secondary infusion errors.

Wind is the second largest renewable energy source after solar. It is one of the fastest growing sources of electricity in the world and currently of wind energy is installed in the United States and an additional is under construction (Office of Energy and Environment Affairs, 2011). For the growth of wind electricity, one of the most prominent environmental concerns relates to the death of birds, bats and other avian species resulting from collision with turbine blades. This thesis develops a model that provides the optimal strategy of turning the turbines off in a wind farm for certain periods to mitigate bird mortalities. We first create a single turbine optimization model for each hour on each day of a single month. We maximize the expected revenue generation and limit the expected bird mortalities to a certain level to solve for the dates and times for which the turbine should be turned off. The optimization problem is found to be part of common class of problems called Knapsack problems and through experiments we conclude that a linear programming (LP) relaxation of the problem provides a near-optimal solution. We extend the single-turbine model to a multiple-turbine model applicable to a wind farm. In this case, we solve for the percentage of wind turbines that should be turned off to limit the expected bird mortalities to a certain level. Finally, we carry out an uncertainty analysis and estimate probability distributions over the outcome of optimal strategy of turning the turbine off. We consider the Cape Wind project as a case study and limit the analysis to only one species of endangered birds called the common loon. We find that in order to save an expected number of 10 such birds in the month of March; we need to turn the turbine off for a total of 23 hours spread over specific dates and times. The average cost per bird was found to be $171.
