Este trabalho analisa o processo de implementação das políticas de certificação ocupacional (de competências) e de avaliação de desempenho (em serviço) de dirigentes escolares, na rede estadual de ensino da Bahia. Busca também aferir a visão que os sujeitos avaliados têm sobre essas políticas. As políticas de certificação e de avaliação de desempenho de dirigentes escolares integraram o Programa Educar para Vencer, formulado em 1999, no Governo de César Borges, em consonância com a reforma gerencialista da administração pública estadual que já vinha sendo planejada, desde a gestão do Governador Antônio Carlos Magalhães (1991-1993) e com a reforma administrativa gerencialista do Estado brasileiro realizada a partir de 1995, durante a presidência de Fernando Henrique Cardoso. Para desenvolver nossa análise, abordamos inicialmente as mudanças ocorridas no mundo do trabalho, a partir da década de 1970 e suas influências nos processos de formação e certificação profissional (baseados em competências). Em seguida, discutimos sobre a lógica que vem norteando a avaliação de profissionais da educação básica no Brasil. No percurso metodológico, além da pesquisa bibliográfica, utilizamos a pesquisa documental e a pesquisa empírica. A pesquisa empírica teve como público-alvo dez diretores escolares da rede estadual de ensino do município de Salvador. Com o estudo realizado, pudemos evidenciar que as políticas de avaliação de dirigentes escolares implantadas na rede estadual de ensino baiana assumem um caráter regulatório do trabalho desses profissionais, com base no mérito individual. Os diretores entrevistados apresentam uma visão equivocada e contraditória com relação à lógica que permeia essas políticas.(AU)

Estudos em ambiente laboral acerca do comportamento humano e saúde no trabalho, bem como a melhor forma de se aplicar as competências e habilidades do trabalhador, vêm ganhando maior corpo devido à crescente busca por melhores resultados organizacionais, ao aumento da competitividade no mercado e à necessidade empresarial de atingir melhor desempenho de suas equipes. Gestores procuram por recursos e inovações a fim de tornar possível o alcance das metas organizacionais. Empregados mais capacitados, satisfeitos e envolvidos com seu trabalho são também aqueles que têm maior comprometimento afetivo com a organização. Para a empresa, isto pode significar um aumento da produtividade, o rebaixamento do número de absenteísmo e turnover. A dimensão saúde no trabalho ganha relevância porque bem-estar no trabalho significa também empregado mais feliz, com menor probabilidade de adoecimento físico, psíquico ou moral, reduzindo custos relativos à restituição da saúde do trabalhador. Por outro lado, estudo realizado sobre a inteligência emocional em gestores sugere que pessoas com alto nível deste tipo de inteligência são capazes de ter relacionamentos mais profundos e constituir uma rede social mais segura, ajudar os outros de seu grupo, bem como desenvolver uma liderança onde se possa construir uma equipe coesa e uma comunicação mais efetiva com os outros e levar a cabo planos estratégicos empresariais com mais eficiência. Este estudo teve como objetivo geral analisar as relações entre as habilidades da inteligência emocional e as dimensões de bem-estar no trabalho. A pesquisa foi realizada em uma empresa do setor de plásticos e metalurgia, em uma amostra constituída por 386 participantes dos sexos masculino e feminino, com faixa etária entre 18 e 58 anos. Foi utilizado para a coleta de dados um questionário composto de quatro escalas que mediram os três componentes de bem-estar no trabalho e as habilidades da inteligência emocional. Os resultados do estudo revelaram que apenas três habilidades da inteligência emocional tiveram correlações significativas com as dimensões de bem-estar no trabalho: empatia, sociabilidade e automotivação. Foram observadas correlações mais significativas entre sociabilidade e bem-estar no trabalho. Portanto, o bem-estar no trabalho parece associar-se às habilidades intelectuais e emocionais dos trabalhadores de serem empáticos, manterem-se automotivados e, especialmente, de estabelecerem e conservarem suas amizades (sociabilidade)

Considerando a acelerada expansão da Educação a Distância (EaD) no Brasil e os desafios que ainda enfrenta, torna-se importante dedicar um olhar cuidadoso sobre as questões envolvidas. Do ponto de vista da Psicologia, o foco no indivíduo que trabalha com EaD é fundamental. Neste contexto, destaca-se o trabalho do tutor, um recorte deste complexo mundo do trabalho em EaD, alvo deste estudo. O desempenho profissional do tutor depende de fatores tecnológicos, ambientais e psicossociais. Neste este estudo, o objetivo foi verificar o impacto que as crenças de autoeficácia no trabalho, a percepção de suporte social e o engajamento no trabalho exercem sobre o desempenho de tutores de disciplinas oferecidas a distância. A pesquisa teve caráter transversal e foi desenvolvida em uma universidade brasileira com sede no Estado de São Paulo. Os 227 tutores participantes atuavam em diferentes localidades do Brasil; 62% eram mulheres, 65% casados, 66% possuíam idades entre 25 e 45 anos e 97% cursou pelo menos especialização. A coleta dos dados foi realizada por meio eletrônico. Foram aplicadas escalas válidas e confiáveis de autoeficácia, engajamento e percepção de suporte social no trabalho, além de um questionário de dados sociodemográficos. Foi ainda realizada pesquisa documental para levantar informações sobre desempenho. Cálculos de médias, desvios-padrão, medianas e quartis revelaram que os tutores possuem bons níveis de autoeficácia, engajamento no trabalho e desempenho. Mais de 75% deles percebem ter acesso a informações suficientes e importantes, bem como contar com relacionamentos confiáveis e afetivos no trabalho, enquanto metade percebe dispor de bons insumos materiais, financeiros, técnicos e gerenciais. Resultados de análises de variância revelaram não haver diferenças entre desempenho de grupos que exercem outras atividades profissionais além da tutoria e os que não exercem, nem entre grupos que possuem e não possuem formação específica para atuar em tutoria em EaD. Resultados de regressões lineares múltiplas revelaram que as crenças de autoeficácia no trabalho, a percepção de suporte social e o engajamento no trabalho não explicam significantemente a variância do desempenho de tutores. Os resultados foram discutidos, sustentados principalmente na pequena variabilidade das notas de desempenho, considerando que 98,8% dos tutores obtiveram pontuação superior à média do instrumento de avaliação utilizado pela instituição, o que pode revelar dificuldades no processo de avaliação ou problemas relativos à validade do instrumento. Discutiram-se, além disso, questões relacionadas ao desempenho humano, como fenômeno complexo e multidimensional, buscando abordar o papel das variáveis do estudo em sua determinação, à luz da literatura especializada. Ao final, foram apresentadas implicações metodológicas, teóricas e práticas, bem como limitações do estudo e agenda de pesquisa.

In recent years, as part of the expansion process of its activities, the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte – IFRN (Federal Institute for Education, Science and Technology of the State of Rio Grande do Norte – IFRN) detected the need to hire more employees for the institution. This expansion process, a policy of the Federal Government, together with the increase of human resources, required the construction of an adequate facility in the municipality of São Gonçalo do Amarante-RN, for training and qualification and as a means of better enabling its personnel. Along with this policy, the Federal Government is also deeply concerned that its buildings be environmentally friendly. This study deals with this subject matter, as it develops an architectural design of a public building with an emphasis upon the reduction of energy consumption, through the study of energy performance factors such as defined by Carneiro (1988) and adapted by the author of the present study. It is known that residential, commercial and public buildings represent about 45 % of energy consumption in Brazil. That is why it is necessary to consider the reduction of such consumption in buildings, as well as the role that professionals, especially architects, play in this issue. The most effective participation in this regard in the field of architecture occurs in the design phase. However, the architectural solution proposed here goes beyond the energy performance factors, since it also involves other aspects, such as the definition of the concept, the parti and the spatial solution itself. In this sense, the architectural project of the Centro de Treinamento dos Servidores do IFRN - CTSIFRN (Training Center for IFRN Personnel – CTSFIRN) is particularly fitting as a subject for research at the Professional Master Program at PPGAU/UFRN, which is devoted to research on architecture, design and the environment.

This work describes the design process of a small recreational gated community in Pium, Nísia Floresta/RN, from concept to final design stages, with emphasis on low environmental impact, thermal comfort and the spatial quality of housing. The process consisted in a review of the literature and relevant standards, studies of design references and architectural programming. The project development was initially focused on the project’s feasibility, with the definition of the number of units, implantation, size and location of the dwellings and the common areas of the development. Two types of houses (four low rise and five duplex units) have been proposed in order to attend the premises of architectural programming. The conception of the architectural design began with the rooms’ zoning according to the lots. This resulted in the pre-selection of three alternatives that were evaluated in terms of spatial quality and environmental performance. The development of sketches focused on the envelope consistent with the bioclimatic guidelines and on the language of the compatible proposal with the lowest possible environmental impact of the building system, which resulted in the selection of the eucalyptus wood type. During the working drawings, the Quality Technical Regulation for the Level of Energy Efficiency Residential Buildings (RTQ -R) was adopted for the evaluation of the envelope, which resulted in "B" level of efficiency for the first case. After minor adjustments, mainly in frames, the efficiency level rose to "A", demonstrating that early project decisions contributed to the envelope energy performance. Besides the design of the two types of units, the final proposal of the gated community includes the design of the equipment for the common areas (entrance, multipurpose room and support and service sector), and the descriptive texts explaining the project and construction’s details.

This research analyses the components of the organizational structure of the UFRN (Rio Grande do Norte Federal University) and to what extent they affect organizational performance. The study, classified as exploratory and descriptive, was conducted in two phases. The first phase consists of a pilot test to refine the research instrument and to identify the latent components of the organizational structure, and the second to characterize these components and thereby establish relationships with organizational performance. In the first phase, the research was conducted in 20 UFRN organizational units with the participation of 84 employees between technical-administrative and teachers, after considering missing values and outliers, while the second phase occurred in two stages: one conducted with 279 valid cases, consisting of technical-administrative and teachers of 37 UFRN units, and another with 112 managers of the institution in the 49 units identified in this research. The instrument adopted in the first phase was composed of 36 indicators of organizational structure, with six extracted and adapted from the instrument developed by Medeiros (2003) and 30 prepared based on the literature review, from Mintzberg (2012), Hall (1984), Vasconcellos and Hemsley (1997) and Seiffert and Costa (2007) and 7 performance indicators adapted from Fleury and Mills (2006), Vieira and Vieira (2003) and Kaplan and Norton (1997) from the self-assessment instrument in use by the university. In this stage the data were analyzed using the techniques of factor analysis and reliability analysis by means of Cronbach’s alpha, aiming to extract the factors representing the components of the organizational structure. In step 1 of the second phase, the instrument, refined and reduced in the previous phase, with 24 variables of organizational structure and 6 for performance was used, while in step 2, a semi-structured interview guide with questions, organized into nine organizational structure elements, was adopted aiming to gather information to understand the relationship of structure to performance of the UFRN. The techniques used in the second phase, as a whole, were factor analysis and reliability analysis to characterize the components extracted in the previous phase and to validate the performance variables and correlation analysis, regression and content analysis to establish and understand the relationship between structure and performance. The results showed, in the two stages, six latent components of organizational structure in the context under study: training and internalization, communication, hierarchy, decentralization, formalization and departmentalization - with high levels of Cronbach's alpha indexes - which can thereby be characterized as components of UFRN structure. Six performance indicators were validated in this study, showing them as efficient and highly reliable. Finally, it was found that the formalization, communication, decentralization, training and internalization components positively affect UFRN performance, while departmentalization has an adverse affect and hierarchy did not show a significant relationship. The results achieved in this work are important in future studies to support the development of a model structure that represents the specifics of the university

Inúmeras estruturas de concreto no Brasil e no mundo estão atingindo o limite de sua vida útil projetada, completando um ciclo de cinco ou mais décadas de uso e operação. Além das estruturas mais antigas, existem ainda estruturas com reduzido tempo de serviço, e qualidade discutível, que já apresentam patologias em estado tão avançado que chegam a comprometer o seu desempenho. Vindo ao encontro dessas necessidades e no sentido de contribuir para o avanço científico e tecnológico do setor, este trabalho apresenta um método para dosagem, preparo e aplicação de argamassas de alto desempenho para recuperação de estruturas deterioradas, além de sugerir procedimentos para a realização desses reparos, fomentando a cultura das manutenções preventivas e desmistificando a complexidade atribuída a tais operações. Para tanto, foram realizados ensaios mecânicos, microestruturais e relacionados à durabilidade em corpos-de-prova moldados com sílica ativa e látex de estireno-butadieno. Os resultados indicaram que a adoção desses ingredientes, na composição da argamassa de reparo, provocou uma redução significativa da permeabilidade total e descontinuidade de poros, assim como promoveu uma melhor integridade dos constituintes da argamassa, traduzindo-se em uma ampliação, expressiva, das suas capacidades mecânicas. Quando comparada aos produtos industrializados da construção civil, com padrões similares, proporcionou uma economia da ordem de 85%, que permitiria recuperar, com os mesmos custos, quase cinco vezes mais estruturas comprometidas. Este estudo, de viés altamente tecnológico, vem oferecer à construção civil uma argamassa polimérica de alto desempenho, com função reparadora e custo mais acessível, que pode ser adotada em canteiros de obras, implementando ações de natureza sustentável e ainda atendendo às atuais exigências elencadas pela literatura, relacionadas à desempenho, vida útil e durabilidade das estruturas reparadas.

This work test the relationship of performance and legal form of microfinance institutions (MFI), in our work MFI can be banks, non-governmental organizations (NGO), cooperatives, non-banks financial institutions (NBFI) or rural banks. We use linear regression model, panel data and variables dummy for the legal forms. Our samples are 243 MFI from all continents, except North America, in the period from 2007 to 2012. We found that bigger MFI generates higher profit, higher returns and higher self-sufficiency rates, so the growing can be a way for consolidation of MFI. For smaller MFI a way can be assimilation or merging with other MFI. Cooperatives, non-bank financial institutions and rural banks can serve more customers, causing greater impact on society, and get higher returns. This suggests the most appropriate legal form for microfinance market can be cooperatives, non-banks financial institutions or rural banks balancing social orientation and profit orientation.

The soursop (A. muricata) is a fruit rich in minerals especially the potassium content. The commercialization of soursop in natura and processed has increased greatly in recent years. Drying fruit pulp in order to obtain the powdered pulp has been studied, seeking alternatives to ensure the quality of dehydrated products at a low cost of production. The high concentration of sugars reducing present in fruits causes problems of agglomeration and retention during fruit pulp drying in spouted bed dryers. On the other hand in relation to drying of milk and fruit pulp with added milk in spouted bed, promising results are reported in the literature. Based on these results was studied in this work drying of the pulp soursop with added milk in spouted bed with inert particles. The tests were based on a 24 factorial design were evaluated for the effects of milk concentration (30 to 50% m/m), drying air temperature (70 to 90 °C), intermittency time (10 to 14 min), and ratio of air velocity in relation to the minimum spout (1.2 to 1.5) on the rate of production, of powder moisture, yield, rate of drying and thermal efficiency of the process. There were physical and chemical analysis of mixtures, of powders and of mixtures reconstituted by rehydration powders. Were adjusted statistical models of first order to data the rate of production, yield and thermal efficiency, that were statistically significant and predictive. An efficiency greater than 40% under the conditions of 50% milk mixture, at 70 ° C the drying air temperature and 1.5 for the ratio between the air velocity and the minimum spout has been reached. The intermittency time showed no significant effect on the analyzed variables. The final product had moisture in the range of 4.18% to 9.99% and water activity between 0.274 to 0.375. The mixtures reconstituted by rehydration powders maintained the same characteristics of natural blends.

The present dissertation aims to analyze the evaluation process of environmental performance inside an organization from the building construction section of civil construction based on the NBR ISO 14031 guidelines, which provide orientation regarding the implementation of this project towards the internal organizational management. The theoretical research has addressed concepts and historical development of environmental management inside organizations, from the emergence of the first models to the strengthening of environmental management through the standardization of the Environmental Management System caused by the publication of ISO 14001. It has also addressed the evaluation of environmental performance, the NBR ISO 14031 (concepts, types of indicators of evaluation of environmental performance, the elaboration process of such indicators, as well as its use and evaluation by the high administration). The research has an applied character, with exploratory and descriptive goals, and a qualitative approach based on case study. The data collection will be made through questionnaires, interviews, and documental analysis. Through the present research project, one expects to learn the elements taken into consideration by the organization for the elaboration and selection of indicators; to identify which interested parties contribute in the aforementioned process; to discover which sources are taken into consideration by the organization while establishing its environmental performance goals; to learn how the different kinds of environmental indicators are handled by organizations on daily basis, considering the existence of interferences on the decision making process, whether or not the interested parties are integrated, and if there is an periodical evaluation of environmental performance and how it is handled. One also expects to identify the opportunities for improvement regarding the organization that is object of study.

The great amount of data generated as the result of the automation and process supervision in industry implies in two problems: a big demand of storage in discs and the difficulty in streaming this data through a telecommunications link. The lossy data compression algorithms were born in the 90’s with the goal of solving these problems and, by consequence, industries started to use those algorithms in industrial supervision systems to compress data in real time. These algorithms were projected to eliminate redundant and undesired information in a efficient and simple way. However, those algorithms parameters must be set for each process variable, becoming impracticable to configure this parameters for each variable in case of systems that monitor thousands of them. In that context, this paper propose the algorithm Adaptive Swinging Door Trending that consists in a adaptation of the Swinging Door Trending, as this main parameters are adjusted dynamically by the analysis of the signal tendencies in real time. It’s also proposed a comparative analysis of performance in lossy data compression algorithms applied on time series process variables and dynamometer cards. The algorithms used to compare were the piecewise linear and the transforms.

A type of macro drainage solution widely used in urban areas with predomi-nance of closed catchments (basins without outlet) is the implementation of detention and infiltration reservoirs (DIR). This type of solution has the main function of storing surface runoff and to promote soil infiltration and, consequently, aquifer recharge. The practice is to avoid floods in the drainage basin low-lying areas. The catchment waterproofing reduces the distributed groundwater recharge in urban areas, as is the case of Natal city, RN. However, the advantage of DIR is to concentrate the runoff and to promote aquifer recharge to an amount that can surpass the distributed natu-ral recharge. In this paper, we proposed studying a small urban drainage catchment, named Experimental Mirassol Watershed (EMW) in Natal, RN, whose outlet is a DIR. The rainfall-runoff transformation processes, water accumulation in DIR and the pro-cess of infiltration and percolation in the soil profile until the free aquifer were mod-eled and, from rainfall event observations, water levels in DIR and free aquifer water level measurements, and also, parameter values determination, it is was enabled to calibrate and modeling these combined processes. The mathematical modeling was carried out from two numerical models. We used the rainfall-runoff model developed by RIGHETTO (2014), and besides, we developed a one-dimensional model to simu-late the soil infiltration, percolation, redistribution soil water and groundwater in a combined system to the reservoir water balance. Continuous simulation was run over a period of eighteen months in time intervals of one minute. The drainage basin was discretized in blocks units as well as street reaches and the soil profile in vertical cells of 2 cm deep to a total depth of 30 m. The generated hydrographs were transformed into inlet volumes to the DIR and then, it was carried out water balance in these time intervals, considering infiltration and percolation of water in the soil profile. As a re-sult, we get to evaluate the storage water process in DIR as well as the infiltration of water, redistribution into the soil and the groundwater aquifer recharge, in continuous temporal simulation. We found that the DIR has good performance to storage excess water drainage and to contribute to the local aquifer recharge process (Aquifer Dunas / Barreiras).
