This dissertation of Mestrado investigated the performance and quality of web sites. The target of the research is the proposal of an integrated model of evaluation of services of digital information in web educational sites. The universe of the research was constituted by eighteen Brazilian Universities that offer after-graduation courses, in the levels of mestrado and doutorado in the area of Engineering of Production. The adopted methodology was a descriptive and exploratory research, using the technique of systematic comment and focus group, for the collection of the data, using itself changeable independent dependents and, through the application of two instruments of research. The analysis protocol was the instrument adopted for evaluation and attainment of qualitative results. E the analysis grating was applied for evaluation and attainment of the quantitative results. The qualitative results had identified to the lack of standardization of web sites, under the attributes of content, hierarchy of information, design of the colors and letters. It of accessibility for carriers of auditory and visual special necessities was observed inexistence, as well as the lack of convergence of medias and assistivas technologies. The language of the sites also was evaluated and all present Portuguese only language. The general result demonstrated in grafico and tables with classification of the Universities, predominating the Good note As for the quantitative results, analysis method ed was estatistico, in order to get the descriptive and inferencial result between the dependent and independent variaveis. How much a category of analysis of the services of the evaluated sites, was found it props up and the index generality weighed. These results had served of base for ranking of existence or inexistence the Universities, how much of the information of services in its web sites. In analysis inferencial the result of the test of correlation or association of the independent variaveis (level, concept of the CAPES and period of existence of the program) with the caracteristicas, called was gotten categories of services. For this analysis the estatisticos methods had been used: coefficient of Spearman and the Test of Fisher. But the category you discipline of the Program of Mestrado presented significance with variavel independent and concept of the CAPES. Main conclusion of this study it was ausencia of satandardization o how much to the subjective aspects, design, hierarchy of information navigability and content precision and the accessibility inexistence and convergence. How much to the quantitative aspects, the information services offered by web sites of the evaluated Universities, still they do not present a satisfactory and including quality. Absence of strategies, adoption of tools web, techniques of institucional marketing and services that become them more interactive, navigable is perceived and with aggregate value

O objetivo deste trabalho foi comparar as estimativas de parâmetros genéticos obtidas em análises bayesianas uni-característica e bi-característica, em modelo animal linear e de limiar, considerando-se as características categóricas morfológicas de bovinos da raça Nelore. Os dados de musculosidade, estrutura física e conformação foram obtidos entre 2000 e 2005, em 3.864 animais de 13 fazendas participantes do Programa Nelore Brasil. Foram realizadas análises bayesianas uni e bi-características, em modelos de limiar e linear. de modo geral, os modelos de limiar e linear foram eficientes na estimação dos parâmetros genéticos para escores visuais em análises bayesianas uni-características. Nas análises bi-características, observou-se que: com utilização de dados contínuos e categóricos, o modelo de limiar proporcionou estimativas de correlação genética de maior magnitude do que aquelas do modelo linear; e com o uso de dados categóricos, as estimativas de herdabilidade foram semelhantes. A vantagem do modelo linear foi o menor tempo gasto no processamento das análises. Na avaliação genética de animais para escores visuais, o uso do modelo de limiar ou linear não influenciou a classificação dos animais, quanto aos valores genéticos preditos, o que indica que ambos os modelos podem ser utilizados em programas de melhoramento genético.

The natural resources degradation and its consequences to the society life have provided several discussions about the evaluation methods and environmental management, and the available means to minimize the effects of man s actions over the environment. Amongst these actions is the encouragement to the community participation in the process of carrying out the environmental programs, considering government and enterprises representatives or residents of certain places as social actors. Within these context, this paper had as a goal the investigation of the public participation in the environmental programs in areas that are susceptible to desertification, specificly in Parelhas/RN. The choice for this town was due to its insertion in an area considered as a desetification nucleous, which is, a region that suffers land degradation as a consequence of climate variations or human activities. Therefore, the research in question, of a descriptive and exploratory type, had as an instrument a structured questionnaire, applied to a sample of 223 people out of an 11,068 over 20 years of age residents population. The data have been tabled from Statistics for Windows Program and later interpreted based on the theoretical reference over the subject. As a result, corroborating to the literature of the area, it was found that the community participation in any type of action or debate about environmental questions is associated to the perception and knowledge about the problems. Although the people who were interviewed believe in the responsibility of the ceramic industry in causing environmental problems, they also believe that the benefits brought by the sector overcome such problems

Os objetivos neste estudo foram estimar parâmetros genéticos das características categóricas musculosidade, estrutura física, aspectos raciais, conformação, ônfalo, pigmentação e sacro e predizer os valores genéticos utilizando-se a estatística bayesiana sob modelo animal de limiar, considerando diferentes idades de bovinos da raça Nelore. As informações de escores visuais foram obtidas nos anos de 2000 a 2005 de bovinos provenientes de 13 fazendas participantes do Programa Nelore Brasil. Nas análises bicaracterísticas, foram utilizados 500.000 até 1.100.000 ciclos para alcançar a convergência da cadeia de Gibbs. O descarte inicial e o intervalo amostral foram de 100.000 e 1.000 ciclos, respectivamente. As características de escores visuais avaliadas aos 8 e 22 meses de idade apresentaram estimativas de herdabilidades moderadas, indicando resposta rápida à seleção direta. Os escores visuais indicaram possibilidade de resposta rápida à seleção direta e, portanto, devem ser incorporados em programas de melhoramento genético como critérios de seleção. As estimativas de correlações genéticas entre musculosidade, estrutura física e conformação também indicam que a seleção direta para uma destas características trará progresso genético às outras. Recomenda-se utilizar os escores visuais como critérios de seleção em pelo menos duas fases de vida do animal, na desmama e ao sobreano.

This thesis aims at analyzing from the perspective of the manager the importance of the use of quality management tools and concepts in Federal Universities. It was motivated by the following research problem: do Federal University managers consider it to be relevant the quality management in their institution? Therefore, we sought to gather evidence for a satisfactory approach that addresses the complexity of the topic researched: quality, higher education and quality management systems. We chose to adopt an applied study, the exploratory-descriptive research as to the objective and the quantitative and qualitative research as to the approach to the problem. The object of study is composed by the Planning Provosts of Federal Universities listed in the University Ranking Sheet - (RUF) in 2013. We chose to restrict the sample listing only the provosts of the 20 best-placed universities in the ranking of the Federal Universities. The research instrument was composed of 26 questions, of which 6 questions were designed to identify the profile of the manager, 16 questions of perception (manifested variables) on the importance of quality management in the University, where the managers assigned values (answers) to the affirmatives (that address the main topic of this thesis) based on a Likert scale of 5 points, and 4 open and optional questions, in order to identify general management practices used. It was used for statistical analysis (data analysis) descriptive and factorial statistics. The responses collected through the questionnaire portray the managers´ perception regarding the importance of quality management in their institutions. Sixteen variables were addressed, the results of factor analysis of importance were "Important" and "Very Important", where the variable (V2) was "Important" and all others "Very important." With this information, it is possible to prioritize some areas that deserve immediate action. As it was observed that some variables are "Very important" for the vast majority of managers, others did not show the same result as example (V2, V10, V11). It is concluded that the manager´s perception of quality management in his or her institution is relevant, but the same importance is not given to quality programs implemented in other segments of the economy, and that, despite the advancements offered by SINAES, the model does not evaluate the institution in a global way. Thus, with the results, it is expected to contribute to the advancement of the subject, trying to arouse interest from the managers of Federal Universities in the subject, emphasizing the importance of quality management systems as a necessary tool to raise the institutional quality

O objetivo neste trabalho foi avaliar economicamente o uso da restrição alimentar qualitativa para suínos machos castrados em terminação sobre o desempenho e as características de carcaça de 60 animais. Dez suínos foram abatidos no início da fase experimental (89,0 ± 4,2 kg) e os demais, alimentados com rações contendo cinco níveis de restrição nutricional qualitativa (0, 5, 10, 15 e 20%), obtidas pela inclusão de casca de arroz finamente moída, até o final do experimento (127,8 ± 2,9 kg). Foram calculados os custos com alimentação durante o período experimental (R$alimento) e estimados os valores de receita bruta de cada carcaça de animais abatidos aos 128 kg (RBsuíno128kg) ou no início do experimento (RBmédia_suíno89kg). A partir destes três dados, foi calculado o resultado líquido (RL) do uso das dietas experimentais (RL = RBsuíno128kg - RBmédia_suíno89kg - R$alimento). Também foram analisadas as variações mensais dos preços do milho, do farelo de soja e do suíno, sendo determinado o preço do milho como o fator de maior impacto sobre a lucratividade do uso da restrição qualitativa. A equação de predição da probabilidade de aumento linear do resultado líquido pelo uso da restrição qualitativa foi determinada em função dos diferentes preços do milho - PM (valor de P RL = 0,392 - 0,625PM, R² = 0,73). Efeito significativo foi observado para preços do milho de cerca de quatro vezes ou mais acima do custo da casca de arroz. Assim, conclui-se que a viabilidade do uso da restrição qualitativa, até o nível de 20%, depende do cenário econômico, mas sobretudo do preço do milho, o principal ingrediente substituído nas rações ao empregar-se a restrição qualitativa, e de sua relação com o custo do resíduo utilizado para diluição energética.

O objetivo deste trabalho foi avaliar o potencial de utilização dos sensores de reflectância e fluorescência na avaliação de teores de N‑NO3‑ no pecíolo, na produção de biomassa e na produtividade do algodoeiro. Utilizou-se o delineamento experimental de blocos ao acaso em arranjo fatorial 3x4, com quatro repetições. Os tratamentos consistiram de três variedades de algodão (ST‑4288‑B2RF, ST‑4498‑B2RF e DP-164‑B2RF) e quatro doses de N (0, 45, 90 e 135 kg ha‑1). Aos 120 dias após a semeadura, foram realizadas leituras com sensores ópticos de reflectância e fluorescência. Não houve correlação significativa dos teores de N‑NO3‑ no pecíolo com os índices de reflectância; porém, houve correlação destes com a produção de biomassa (0,39) e a produtividade (0,32 a 0,41). Os índices do sensor de fluorescência correlacionaram-se significativamente com teores de N‑NO3‑ no pecíolo (0,34 a 0,61), produção de biomassa (0,30 a 0,53) e produtividade (0,34). em comparação com os índices de reflectância, os de fluorescência apresentam maior capacidade de avaliar os teores de N‑NO3‑ no pecíolo, capacidade semelhante em detectar variação na biomassa e menor capacidade de detectar variação da produtividade do algodoeiro, quando se aplicam doses crescentes de N.

Este projeto teve por objetivo avaliar a eficácia de herbicidas para controle de plantas aquáticas submersas das espécies Egeria densa e Egeria najas. O estudo foi realizado em três etapas consecutivas: em laboratório, em caixas d'água e numa represa de pequeno porte, sem fluxo de água. Na primeira etapa, avaliou-se a eficiência de 23 herbicidas utilizados em áreas agrícolas e disponíveis no mercado brasileiro. As elevadas concentrações em que os herbicidas foram efetivos inviabilizam programas de controle fundamentados em uma única aplicação. No experimento em caixas d'água, foram avaliados os efeitos de doses crescentes de fluridone, nas formulações líquida e granulada, no controle de Egeria densa e Egeria najas. Foram testadas as concentrações de 10, 20, 40, 80 e 150 ppb de fluridone na formulação líquida e 20, 40, 80 e 150 ppb na granulada. Após uma única aplicação, os resultados indicaram que o fluridone, nas concentrações de 80 e 150 ppb, em ambas as formulações, foi eficaz no controle dessas duas espécies. No experimento em represa de pequeno porte sem fluxo de água, avaliou-se o efeito da manutenção das concentrações de fluridone no controle de Egeria najas. Uma represa de 1.980 m² foi tratada com sete aplicações de fluridone, na formulação líquida, visando a manutenção das concentrações do ingrediente ativo na água entre 10 e 20 ppb. Os resultados indicaram que o controle proporcionado pelo herbicida foi superior a 99%. Não houve modificação significativa nas características relacionadas à qualidade da água.

The reality of water resources management in semiarid regions, such as the Seridó region, has been shaped by a complex chain involving social-cultural, political, economic and environmental aspects, covering different spheres of activity - from local to federal. Because water is a scarce element, the most rational way pointed out by our recent history has been to move towards an increasing emphasis on the need for a truly rational, integrated, sustainable and participatory water resources management, supported by legislation and by a network of institutions that could materialize it. In this sense, despite all the advances in the formulation of public policies in water resources, which ones have indeed lead to significant changes that have occurred or are underway in semiarid regions such as Seridó? What factors may be preventing the realization of the desires rationality embedded in the framers of water policies intents? How to properly manage water resources if the current actors who promote their management and the political, human, cultural and institutional processes that intervene in this management, show strong traces of unsustainability? The research methodology adopted in this paper led to a breakdown of the traditional approach to water resource management, to integrate it into other areas of knowledge, especially to political science and public administration, catalyzed by the concept of "sustainable development". From a broad, interdisciplinary literature review, an exhaustive characterization of the river basin Seridó, a set of interviews with key people in the public administration acting in the region, a series of diagnoses and a set of propositions were made in order to correct the direction of current public policies for the region. From the point of view of public policies, it is in the deployment phase, not in its formulation, which lies a major problem of the lack of significant progress in water management. The lack of coordination between government programs are well characterized, as well as the lack of efficiency and effectiveness of their actions. The causes of this secular model are also discussed, including political factors and social relations of production, which led to a stalemate difficult, but of possible solution. It can be perceived there is a scenario of progressive deterioration of natural resources of the fragile ecosystem and a network of environmental and social consequences difficult to reverse, the result of a persistent and inertial sociopolitical culture, whose main factors reinforce itself. The work leads towards a characterization of the water resources management also from the perspective of environmental, institutional, political and human sustainability , the latter being identified, particularly as investment in the development of people as autonomous beings - not based in ideological directives of any kind - in the emancipation of the traditional figure of the poor man of the hinterland" to the "catalyst for change" responsible for their own decisions or omissions, based upon an education for free-thinking that brings each one as co-responsible epicenter of (self-) sustainable changes in their midst
