O contexto hodierno caracteriza-se como um panorama de uso contínuo de informação nas mais variadas esferas da sociedade. A informação é usada em diversos contextos sob vários formatos e isso se torna possível com a evolução tecnológica realizada em ritmo acelerado, sobretudo nos últimos dois séculos. Essa evolução trouxe consigo a possibilidade ampliada de acesso à informação, mas por outro lado, impôs desafios circunstanciais no seu tratamento e difusão. Nos diversos tipos de unidades de informação, faz-se necessária a adoção de estratégias para a melhoria do gerenciamento e desenvolvimento das coleções, sobretudo as coleções digitais. De tal modo, o trabalho visa a traçar um panorama ligado às questões relacionadas à comunicação cientifica com a bibliotecas universitárias, com vistas a ampliar o debate sobre o desenvolvimento digital de coleções de periódicos em bibliotecas universitárias, bem como aspectos relacionados à adoção de critérios de seleção e avaliação destes itens de informação. Aborda os casos específicos, como o do Portal Capes e o SciELO como coleções digitais de periódicos sujeitos a estratégias de desenvolvimento das coleções. Aponta opções para a melhoria da gestão da coleção digital em bibliotecas universitárias. A metodologia empregada foi a de pesquisa bibliográfica em uso de fontes eletrônicas e convencionais, bem como análise de critérios utilizados na Avaliação e Coleções para Bibliotecas Universitárias e o Indicadores Qualis pela Condenação de Aperfeiçoamento de Pessoa de Ensino Superior (CAPES).

In an environment of constant change, technological developments, market competition and more informed consumers, the search for a lasting relationship through the conquest of loyalty has become the objective of companies. However, several authors suggest that this loyalty can be affected by negative comments available on the internet. Therefore, this dissertation has as objective to examine if the complaints are available on the internet impact the loyalty to a brand of mobile phone. The research used as the basis the Expanded NCSB model suggest by Johnson et al. (2001), studying five prominent drives of loyalty: image/brand reputation, affective commitment, calculative commitment, perceived value and trust, beyond the satisfaction construct as moderator variable. The research method adopted was the experimental design which included 285 undergraduate students, with the trial which included 285 undergraduate students, with the field study of the mobile industry, specifically, the brands of cell phones. The research approach was quantitative and methods were descriptive statistics, factor analysis, cluster analysis, linear regression and non-parametric test of Wilcoxon for data analysis. Of the 16 hypothesis stemmed from the research model proposed, 12 were confirmed. The results showed that the complaint available on the internet, here represented by the available on the site Reclame Aqui, may impact consumer perceptions about brand loyalty, as well as its antecedents, being that these complaints can affect all the consumers, regardless of historical satisfaction with the brand. It also noted the positive relationship between the independent variables trust, image/brand reputation, perceived value, affective commitment and calculative commitment and the dependent variable - loyalty, even when considering the data obtained after exposure to the complaint. However, no unanimous conclusion that the relationship between these variables was strongest in the group with satisfactory experience. At the first moment of the research, the trust was the most important variable for the formation of loyalty. However, after exposure to treatment, the image/brand reputation, was more relevant. Contributions of the study, limitations and recommendations for future researches are approached in the present investigation

The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pollution resulting from inappropriate management of residues. Thus, is necessary achieve a new equilibrium between the grow from raw materials and energy and the residue generation. This equilibrium should be achieved by technical and economic feasibility of environmental supported models through recycling and reuse. The red ceramic industry stand out in residue absorption question as raw material due their clay mass heterogeneity, constituted by clay minerals and non-clay minerals with wide mineralogical variation, allowing residue inclusion which act like plastic or non-plastic materials, contributing to retain heavy metals contained in residues in the vitreous mass formed during the burning of the ceramic bodies. This work propose the study of the influence of incorporation of 25 wt.% sludge from wastewater treatment plant, according preliminary results, in the mass to produce ceramic bodies. The raw materials was characterized through chemical composition analyses by XRF, mineralogical analyses by XRD, thermal analyses by TG and DTA, Atterberg limits and thermodilatometry. Subsequently was composed the mass with 75 wt.% of clay and 25 wt.% of dried wastewater sludge from UFRN WWTP. Samples with 6,0 x 2,0 x 0,5 cm was produced with unidirectional compacting under pressure of 20MPa and burned in temperatures between 950 and 1,200ºC. After fired, the ceramic bodies have been submitted to physical and mechanical analyses through the measure of firing shrinkage, water absorption, density, apparent porosity and flexural strength; crystallographic analyses through XRD and microstructure analyses by SEM. The technological properties obtained was satisfactory to production of roof tiles with 25 wt.% at 1,200 ºC, but the production of others products at lower temperatures was not feasible

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.
