Atualmente a análise de pontos de função é a técnica mais utilizada entre as organizações brasileiras. Por outro lado, o COSMIC é uma técnica de medição considerada como a segunda geração em método de medição funcional de projetos de desenvolvimento e manutenção de software, sendo precisa e abrangente para medir software e estimar esforço de desenvolvimento, despertando o interesse do mercado de desenvolvimento de software por essa métrica. Quando considerada a migração das bases históricas de medição de software das organizações para uma nova unidade de medida, há como consequência um alto custo para se medir os projetos legados. Nesse sentido, o objetivo desse trabalho é propor uma alternativa para migração de bases históricas de Pontos de Função para o COSMIC. A abordagem propõe uma fórmula de conversão, o qual foi encontrada a partir da medição de quatro projetos de desenvolvimento de software analisados nessas duas técnicas, para atualizar seus dados sem o custo de refazer toda sua base histórica. / There is a tendency in software development and maintenance organizations in using Function Points as a standard measure in their measurement processes. Currently the analysis of function points is the most used technique among Brazilian organizations. On the other hand, COSMIC is a measurement technique considered as the secondgeneration method of functional measurement for software development and maintenance projects, with an accurate and comprehensive approach to measure and estimate software development effort, arousing interest of software development market for this metric. When organizations are considering the migration of their historical measure basis for a new measurement unit, there is a consequent high cost to measure the legacy projects. In this sense, the purpose of this work is to propose an alternative to migrate historical bases of Function Points to COSMIC. The approach proposes a conversion factor, which was found from the measurement of four software development projects analyzed in these two techniques to update its data without the cost of redoing the entire historical basis.

During 20th century main concern was to have sanitary water flowing through the tap. In 21st century constant supply of safe drinking water is common at any home in USA. Hence consumers pay attention to aesthetic quality of tap water. Odorous algal metabolites in source water and metals introduced to drinking water due to corrosion of pipes in the distribution system cause taste, odor and color problems, and result in complaints and perception of tap water as unhealthy. Millions of dollars are spent each year by water industry to address and prevent these issues. This research focused on some of the taste-and-odor issues associated with drinking water. First aim was to understand when geosmin, 2-MIB, and nonadienal become detectable, employing two-resistance mass transfer theory to determine the concentration of odorants in bathroom air. Results showed that water temperature and odorant concentration in water play an important role. Next focus was to develop an international odor standard to be used for training of sensory analysis panelists. There are many sensory methods to monitor drinking water to detect the off-flavors however an odor standard has been missing. Hexanal was studied with trained flavor profile analysis panels and was proposed as an ideal odor reference standard to be used for training and sensory assessment of water samples. Main focus was to understand metallic flavor of drinking water caused by iron and copper. It was shown that metallic sensation has taste and retronasal components creating the flavor and humans are very sensitive to it. Occurrence of lipid oxidation in the oral cavity was shown when metals were ingested, that produces carbonyls which are responsible for the metallic flavor. Antioxidants and chelators were investigated to study prevention of lipid oxidation and, chelators were determined to be more effective. Oral epithelial cell cultures were developed as a model for oral cavity to further investigate lipid oxidation and effectiveness of the antioxidants and chelators. This dissertation is a result of inter-disciplinary work and possibly a good example for how problems may be solved by incorporating different methods and point of views from several disciplines. / Ph.

Utilizing survey data gathered from local local level floodplain administrators (FPAs) operating within Federal Emergency Management Agency Region 6, this study provides a more nuanced understanding of perceived competency among FPAs across key floodplain management topics through the use of a principal component analysis (PCA). PCA identified six distinct components related to perceived competency among FPAs including; Modification and Update Process, General Knowledge, Grants and Programs, Analysis, Development and Real Estate, and Administration and Outreach. The study then employed regression analyses to identify organizational and individual level characteristics that predict perceived competency. Data analyses identified several organizational variables as significant positive predictors of perceived competency including working within an urban community, full-time job status and overall workload percentage dedicated to floodplain management. Additionally, several individual characteristics such as educational attainment, professional certification, previous disaster experience, and years of experience working as an FPA were also identified as significant positive predictors of perceived competency. Based on these findings the study makes several recommendations about improvements to training and educational materials for practitioners and students.

Esta dissertação tem como tema as relações que a agricultura familiar estabelece com os mercados e o papel das políticas públicas nesse processo, sendo o Programa de Aquisição de Alimentos – PAA o principal objeto de estudo. A escolha do PAA deve-se ao fato do programa não se caracterizar como uma política meramente assistencialista. É um programa com múltiplas facetas, tem o interesse duplo de fortalecer a agricultura familiar, mantendo-a no campo, valorizando suas tradições, melhorando sua renda, estimulando relações de produção e consumo locais e, ao mesmo tempo, abastecer a rede socioassistencial da região em que é operacionalizado. Para melhor compreender estas questões foi realizado um estudo de caso sobre o PAA no município de Varginha com o objetivo geral de analisar como o PAA contribui para o fortalecimento das relações de mercado e para a inserção da agricultura familiar em diferentes redes de comercialização na microrregião de Varginha. A coleta de dados do trabalho empírico ocorreu em duas etapas, na primeira os dados foram obtidos através de pesquisa documental e na segunda etapa através de entrevistas em profundidade direcionadas aos agricultores familiares ativos no PAA Varginha. A elaboração do roteiro de perguntas que direcionou as entrevistas foi precedida pela construção de três categorias analíticas que nortearam a articulação das perguntas e posteriormente fundamentaram a interpretação final dos dados. As categorias criadas foram Segurança alimentar e nutricional, Inclusão econômica e social da agricultura familiar e Fortalecimento de circuitos locais de comercialização. Os dados coletados foram analisados através do método Análise de Conteúdo Categorial proposto por Bardin (2011). Para a realização da análise dos dados foram criadas três subcategorias para cada uma das categorias analíticas mencionadas anteriormente. Através do estudo de caso constatou-se que em Varginha o PAA contribui para o fortalecimento da agricultura familiar e para sua inserção no mercado à medida que incentiva que os beneficiários fornecedores a ampliarem e diversificarem a produção familiar. Além disso, o programa tem contribuído nesse município para melhorar a renda dos agricultores que passam a investir na infraestrutura da propriedade e também na produção de alimentos, com maior capacidade de investimento são capazes de procurar novos mercados regionais. Saliente-se que o próprio PAA Varginha apresenta-se como uma nova rede de comercialização que mantém outras redes como a do café, por exemplo, diagnosticada como a principal rede de comércio dos agricultores envolvidos na pesquisa. / This dissertation approaches the relationship established by family-farming with the market and the role of public policies in this process in the light of the Food Acquisition Program (FAP), the core object of this study, which was chosen due to its non-handout policy profile. FAP is a multi faceted program that intends to reinforce the family agriculture by keeping families farming, valorizing their tradition, improving their income, stimulating the interaction between production and local consumption while supplying the social aided region net where the program is managed. To understand better those questions it was conducted a case study about the FPA in the county of Varginha in order to analyze how FPA contributes to both consolidate market relations and inserting family-farming in different commercialization nets in the Microregion of Varginha. Data collection of empirical work occurred in two stages, the first data were obtained through desk research and in the second phase by depth interviews directed to active farmers in PAA Varginha. The preparation of the questions guide which guided the interviews was preceded by the construction of three analytical categories that oriented the articulation of the questions and later validated the final interpretation of the data. The categories created were food and nutrition safety, family-farming economic and social inclusion and Strengthening of local marketing channels. The collected data were analyzed using the method of Categorical Content Analysis proposed by Bardin (2011). To perform the data analysis three subcategories were created for each of the analytical categories previously mentioned. Through the case study it was found that in Varginha, PAA contributes to the strengthening of family-farming and its insertion into the market, considering that it encourages the beneficiary suppliers to enlarge and diversify the family production. Beyond that, the program has contributed to the county to improve the income of the family-farmers who started to invest in the infrastructure of their property and also in food production, by increasing their investment capacity they will be able to look for new regional markets. Note that PAA Varginha presents itself as a new marketing network that keeps other networks like coffee, for instance, diagnosed as the main trading network of farmers involved in the research.

Paralelo a este crescimento, o Brasil continua se tornando cada vez menos rural. Esta aparente contradição sugere duas explicações. A primeira delas é que a agenda rural se apoia no próprio voto rural, que por sua vez é sobre-representado eleitoralmente. A segunda delas é que a agenda rural seria justificada por outros fatores externos às eleições, sobretudo o financiamento eleitoral. Este trabalho analisa e testa estas hipóteses com o intuito de explicar o que sustenta a agenda rural na 54 a Legislatura da Câmara dos Deputados (2011-2015). O principal elemento a ser explicado foi o conjunto de proposições de políticas públicas traduzidas em Projetos de Emenda à Constituição, Projetos de Lei, Requerimentos e Indicações. Os fatores explicativos utilizados foram (i) o voto rural (calculado com base na distribuição demográfica por município), (ii) o que chamo de “voto agropecuário” (calculado com base na distribuição do PIB agropecuário municipal), (iii) o financiamento de campanha, (iv) as profissões declaradas pelos deputados e (v) o nível de segurança eleitoral dos mesmos. Com estas mesmas variáveis, esta pesquisa buscou explicar a formação da Frente Parlamentar da Agropecuária – FPA, da Comissão de Agricultura, Pecuária, Abastecimento e Desenvolvimento Rural da Câmara dos Deputados – CAPADR, e a votação nominal do primeiro turno do Código Florestal. Os resultados dos testes empíricos mostram que deputados ruralistas não respondem ao voto rural. No entanto, eles respondem ao voto agropecuário, sendo esta a correlação mais forte. O financiamento de campanhas e a profissão declarada pelos deputados são relevantes para a priorização da agenda rural, e a CAPADR é o espaço político onde esta priorização ocorre. Por fim, as variáveis utilizadas para explicar o comportamento pró-ativo dos deputados não servem para interpretar a votação nominal do Código Florestal, que pode ser mais bem explicado pelo ambiente legislativo do que pelas bases eleitorais ou financiamento de campanha dos parlamentares. / The Congressional Rural Caucus in the Chamber of Deputies has grown in number and influence. Parallel to that, Brazil has continued to become less and less rural. That seeming contradiction suggests two explanations. The first one is that the rural agenda is based on the rural vote, which is overrepresented. The second one is that the rural agenda is justified by other factors external to the elections, mainly campaign financing. The current work analyses and tests these hypotheses aiming to explain what gives support to the rural agenda in the Chamber of Deputies’ 54 th Legislature (2011-2015). The main element to be explained is the group of policy proposals formed by Constitutional Amendments, Ordinary Bills, Petitions and Indications. The possible explanations are (i) the rural vote (based on the demographic distribution per municipality), (ii) what I call “agribusiness vote” (based on the distribution of the agricultural GDP per municipality), (iii) the campaign financing, (iv) the declared profession of the representatives and (v) their level of electoral safety. Using the same variables the current research explained the composition of the Agricultural Parliamentary Front, the composition of the Agricultural Permanent Commission of the Chamber of Deputies, and the first round roll call voting for the Forest Code. The results of the empirical tests show that rural representatives are not responsive to the rural vote. However, they are responsive to the agribusiness vote with which the correlation is strongest among the variables. The representatives’ campaign financing and declared professions are relevant for prioritizing the rural agenda, and the Agricultural Commission is the political place where it happens. The independent variables applied to explain the representatives’ proactive policy propositions cannot be used to interpret the roll call voting of the Forest Code, which could be better explained by the legislative modus operandi than the representatives’ electoral context.

This Master's thesis examines the possibility of implementing an intelligent transport system for monitoring road vehicles carrying dangerous goods through the territory of the Czech Republic, for the purpose of providing relevant information to emergency responders in the event of an accident involving such vehicles. The aim is to explore whether, and how, can radio-frequency identification technology be used in such a system. The scope of the research is not limited to technical aspects of the solution. Various options are considered in terms of capital costs, complexity of the required information system and impact on shippers and carriers from an economic and business process standpoint. The paper briefly describes the current legislation concerning the transport of dangerous goods, the existing processes and entities involved in transport and handling of traffic accidents. Following is a comparison of several possible implementations of the monitoring system.

Russian government justified the war with Georgia by a set of normatively-legislative arguments. Intervention in Georgia was in accordance to those arguments legitimate. This rationalization proved to be invalid. Main goal of this diploma thesis was therefore to find Russian motives for the war with Georgia. Our hypothesis was that the reaction to Georgian military operation in South Ossetia was a result of a certain dilemma in Russian government. We used two methodological concepts introduced in the book of Graham T. Allison "Essence of Decision: Explaining the Cuban Missile Crisis" for the analysis. The first model, "rational actor", presumes that countries act in the international relations always rationally. "Rational actor" showed that Russian reaction was a result of the rational choice - Russia evaluated military confrontation with Georgia as the most advantageous alternative. The governments' behavior is in accordance to the second model, "organizational process", always limited by behavior of their parts - organizations. The second model revealed that the Russian reaction was result of activated programs, whose character led to massive military action. Our analysis showed that the model which fits better in the case of finding motives of Russian government for the intervention in Georgia...
