Recently, Brazilian scientific production has increased greatly, due to demands for productivity from scientific agencies. However, this high increases requires a more qualified production, since it s essential that publications are relevant and original. In the psychological field, the assessment scientific journals of the CAPES/ANPEPP Commission had a strong effect on the scientific community and raised questions about the chosen evaluation method. Considering this impact, the aim of this research is a meta-analysis on the assessment of Psychological journals by CAPES to update the Qualis database. For this research, Psychology scientific editors (38 questionnaires were applied by e-mail) were consulted, also 5 librarians who work with scientific journals assessment (semi-structured interviews) and 8 members who acted as referees in the CAPES/ANPEPP Commission (open questions were sent by e-mail). The results are shown through 3 analysis: general evaluation of the Qualis process (including the Assessment Committee constitution), evaluation criteria used in the process and the effect of the evaluation on the scientific community (changes on the editing scene included). Some important points emerged: disagreement among different actors about the suitability of this evaluation model; the recognition of the improvement of scientific journals, mainly toward normalization and diffusion; the verification that the model does not point the quality of the journal, i.e., the content of the scientific articles published in the journal; the disagreement with the criteria used, seemed necessary and useful but needed to be discussed and cleared between the scientific community. Despite these points, the scientific journals evaluation still is the main method to assure quality for Psychology publications

The Triennial Evaluation of Coordination for the Improvement of Higher Education Personnel (CAPES) is made according to several indicators, divided into several issues and items, and their weights. In these it is evident the importance of scientific periodicals. This study aims to evaluate the relative efficiency of post-graduate students in Business Administration, Accounting and tourism evaluated by CAPES in Brazil. The methodology used the data envelopment analysis - DEA (Data Envelopment Analysis). The data were obtained from the site and organized by the CAPES Qualis score. The analysis was performed by the DEA variable returns to scale, product-oriented (BCC-O), with data from the three-year periods 2004-2006 and 2007-2009. Among the main results are the average increase significantly the relative efficiency of the programs in the period 2007-2009 compared to 2004-2006 period, the highest average efficiency of programs linked to public institutions in relation to private, doctoral programs with the present average efficiency sharply higher than those only with masters, and senior programs in general were more efficient. There is also moderate and significant correlation between the efficiency scores and concepts CAPES. The Malmquist index analysis showed that more than 85% of programs had increased productivity. It is noteworthy that the main effect that influences the increase of the Malmquist index is the displacement of the border (Frontier-shift)

From their early days, Electrical Submergible Pumping (ESP) units have excelled in lifting much greater liquid rates than most of the other types of artificial lift and developed by good performance in wells with high BSW, in onshore and offshore environments. For all artificial lift system, the lifetime and frequency of interventions are of paramount importance, given the high costs of rigs and equipment, plus the losses coming from a halt in production. In search of a better life of the system comes the need to work with the same efficiency and security within the limits of their equipment, this implies the need for periodic adjustments, monitoring and control. How is increasing the prospect of minimizing direct human actions, these adjustments should be made increasingly via automation. The automated system not only provides a longer life, but also greater control over the production of the well. The controller is the brain of most automation systems, it is inserted the logic and strategies in the work process in order to get you to work efficiently. So great is the importance of controlling for any automation system is expected that, with better understanding of ESP system and the development of research, many controllers will be proposed for this method of artificial lift. Once a controller is proposed, it must be tested and validated before they take it as efficient and functional. The use of a producing well or a test well could favor the completion of testing, but with the serious risk that flaws in the design of the controller were to cause damage to oil well equipment, many of them expensive. Given this reality, the main objective of the present work is to present an environment for evaluation of fuzzy controllers for wells equipped with ESP system, using a computer simulator representing a virtual oil well, a software design fuzzy controllers and a PLC. The use of the proposed environment will enable a reduction in time required for testing and adjustments to the controller and evaluated a rapid diagnosis of their efficiency and effectiveness. The control algorithms are implemented in both high-level language, through the controller design software, such as specific language for programming PLCs, Ladder Diagram language.

In Brazil school food is constitutionally guaranteed to public school students at the preschool and elementary level. This food must be nutritious, hygienic and sanitary. The aim of the present study was to assess the hygienic/sanitary conditions of food and table utensil handlers in municipal public schools in Natal, Brazil. In total, 27 public schools were assessed, using a checklist and microbiological analysis of the hands and table utensils. For the microbiological analyses of the hands, coliforms were analyzed at 45ºC and for the utensils aerobic mesophilic bacteria, using methods recognized by AOAC, 2002 and APHA, 1992, respectively. Most of the schools studied did not exhibit good food and utensil handling practice procedures in any of the variables analyzed. It was shown that 74.1% of the handlers received no periodic training, 51.9% did not undergo annual health examinations and 100% did not practice proper hand hygiene, which reflected significantly (p < 0.05) in hand contamination, where fecal coliforms were detected on 55.6% of the hands analyzed. With respect to the utensils, it was found that 100% of the schools studied did not follow correct hygiene practices and most were classified as very bad ; that is, aerobic mesophilic bacteria values above the limits established by PAHO (Pan American Health Organization), with schools in the north and south districts recording the highest percentages. The results show that the hygienic-sanitary conditions of the food and utensil handlers in the schools studied were inadequate, demonstrating the need for implanting good handling practices aimed at protecting the health of children that take part in the program and offering safer foods. Researchers from the areas of food microbiology, nutrition, public health and statistics participated in this study, a decisive factor for characterizing it as multidisciplinary

Psychologist s social commitment in scientific articles published in scientific papers in Brazil. A situation analysis of the scientific production concerning psychologist s social commitment can aid the historical constitution of this theme and also subsidize reflections about the course of this profession in Brazil. In order to contribute to this debate, the theme social commitment of psychologist was analyzed in the scientific literature concerning psychologist profession in the country. Specifically, papers about the profession that mentioned the theme social commitment were characterized and their approach of this matter was analyzed. In order to accomplish these goals, two research stages were fulfilled: first, in a systematic search for scientific literature in internet databases, studies about the psychologist profession in the country were gathered; in the second stage, scientific papers relating to social commitment in their titles, abstracts or keywords were selected. 61 papers were retrieved, organized in electronic database and full-text analyzed, based in two axis: scientometric and thematic. The papers were identified, in general, as recent, of theoretic character and aligned with several Psychology subareas; mainly produced in public universities, in country s southwest; were of conjunctural interest to the authors research projects, individually published, by professors in touch with post-graduation; published in open access journals, with high Qualis evaluation. It was verified that there is no consensus on the meaning of the theme, prevailing definitions concerning the understanding of the social reality, to the majority of people or to a progressive-aligned professional performance. Are adduced as committed agents: the psychologist (sometimes together with other kinds of professionals or with users), the academia, and the representative entities of the profession. Depending on the subareas and the nature of study, all papers mentioned at least one of the following criteria: expansion of target-audience, renewal of practices, political direction, defined theoretical approach or adequate technical competence, sometimes relating each other. In short, psychologist s social commitment is a contradictory issue which have earned projection in scientific literature, reiterating the historical custom of evaluate the psychologist profession. As conclusion, it is regarded as indispensable to intensify the reflection about the role whose psychologist plays in a class-cleaved society and the limits and potentials of his performing in that framework.

The Brazilian CAPES Journal Portal aims to provide Information in Science and Technology (IST) for academic users. Thus, it is considered a relevant instrument for post-graduation dynamics and the country´s Science and Technology (S&T) development. Despite its importance, there are still few studies that focus on the policy analysis and efficiency of these resources. This research aims to fill in this gap once it proposes an analysis of the use of the CAPES Journal Portal done on behalf of the master´s and doctoral alumni of the Post Graduate Program in Management (PPGA) at the Federal University of Rio Grande do Norte (UFRN). The operationalization of the research´s main objective was possible through the specific objectives: characterize graduate profile as CAPES Journal Portal users b) identify motivation for the use of CAPES Journal Portal c) detect graduate satisfaction degree in information seeking done at CAPES Journal Portal d) verify graduate satisfaction regarding the use of the CAPES Journal Portal e) verify the use of the information that is obtained by graduates in the development of their academic activities. The research is of descriptive nature employing a mixed methodological strategy in which quantitative approach predominates. Data collection was done through a web survey questionnaire. Quantitative data analysis was made possible through the use of a statistical method. As for qualitative analysis, there was use of the Brenda Dervin´s sense-making approach as well as content analysis in open ended questions. The research samples were composed by 90 graduate students who had defended their dissertation/thesis in the PPGA program at UFRN in the time span of 2010-2013. This represented by 88% of this population. As for user profile, the analysis has made evident that there are no quantitative differences related to gender. There is predominance of male graduates that were aged 26 to 30 years old. As for female graduates, the great majority were 31 o 35 years old. Most graduates had Master´s degree scholarship in order to support their study. It was also seen that the great majority claim to use the Portal during their post graduation studies. The main reasons responsible for non use was: preference for the use of other data bases and lack of knowledge regarding the Portal. It was observed that the most used information resources were theses and dissertations. Data also indicate preference for complete text. Those who have used the Portal also claimed to have used other electronic information fonts in order to fulfill their information needs. The information fonts that were researched outside in the Portal were monographs, dissertations and thesis. Scielo was the most used information font. Results reveal that access and use of the Portal has been done in a regular manner during post graduation studies. But on the other hand, graduates also make use of other electronic information fonts in order to meet their information needs. The study also confirmed the important mission performed by the Portal regarding Brazilian scientific communication production. This was seen even though users have reported the need for improvement in some aspects such as: periodic training in order to promote, encourage and teach more effective use of the portal; investment aiming the expansion of Social Sciences Collection in the Portal as well as the need to implement continuous evaluation process related to user satisfaction in regarding the services provided.
