Ciência, teoria social contemporânea e educação

Os modelos científicos vigentes acabam por refletirem sempre nas práticas escolares, nas pedagogias dominantes, na educação. O objetivo principal deste ensaio é correlacionar os paradigmas científicos com os paradigmas pedagógicos e mostrar como, em parte, “somos filhos de Descartes”. Foi com ele que aprendemos o que era a ciência, o método científico, no singular, e a objetividade como valor sagrado da ciência. Foi o seu Discurso do Método que marcou a ciência do século XX e, também, a pedagogia escolar e a educação em geral. Aprendemos a pensar com a cabeça e não com o coração; desumanizamos, desantropomorfizamos a ciência, o que teve efeitos diretos na educação, essencialmente durante toda a primeira metade do século XX. As Ciências da Educação são assim, a nosso ver, no seu início, mais filhas das ciências experimentais e naturais do que das próprias ciências humanas e sociais. De resto, também elas buscavam para si o estatuto de ciências, procurando generalizar o por vezes não generalizável; procurando leis em que imperam a especificidade e a idiossincrasia do humano. Então, o positivismo do século XIX e do início do século XX, que marca as Ciências Sociais e as Ciências da Educação, que se recusam a ser subjetivas, a serem simplesmente humanas, e, logo, não científicas, vigorou e vigora, ainda, na ciência e na educação.

Modelo institucional do processo de estruturação de empresas de desenvolvimento de software: um estudo de múltiplos casos

Some authors have shown the need of understanding the technological structuring process in contemporary firms. From this perspective, the software industry is a very important element because it provides products and services directly to many organizations from many fields. In this case, the Brazilian software industry has some peculiarities that distinguish it from other industries located in developed countries, which makes its understanding even more relevant. There is evidence that local firms take different strategies and structural configurations to enter into a market naturally dominated by large multinational firms. Therefore, this study aims to understand not only the structural configurations assumed by domestic firms but also the dynamic and the process that lead to these different configurations. To do so, this PhD dissertation investigates the institutional environment, its entities and the isomorphic movements, by employing an exploratory, descriptive and explanatory multiple cases study. Eight software development companies from the Recife's information technology Cluster were visited. Also, a form was applied and an interview with one of the main firm s professional was conducted. Although the study is predominantly qualitative, part of the data was analyzed through charts and graphs, providing a companies and environment overview that was very useful to analysis done through the interviews interpretation. As a result, it was realized that companies are structured around hybrids business models from two ideal types of software development companies, which are: software factory and technology-based company. Regarding the development process, it was found that there is a balanced distribution between the traditional and agile development paradigm. Among the traditional methodologies, the Rational Unified Process (RUP) is predominant. The Scrum is the most used methodology among the organizations based on the Agile Manifesto's principles. Regarding the structuring process, each institutional entity acts in such way that generates different isomorphic pressure. Emphasis was given to entities such as customers, research agencies, clusters, market-leading businesses, public universities, incubators, software industry organizations, technology vendors, development tool suppliers and manager s school and background because they relate themselves in a close way with the software firms. About this relationship, a dual and bilateral influence was found. Finally, the structuring level of the organizational field has been also identified as low, which gives a chance to organizational actors of acting independently

Gerenciamento de impressões e qualidade dos serviços em hotéis da Paraíba

The present study has got as its aim to show how the impressions management is being used by the hotels in Paraiba State. For that, the dramma or role play perspective has been adopted as a model for service management. From the theater metaphor, the physical environment and its components can be seen as a scenery of the service show. We conduct the reader to notice the importance of the consummer about the service quality demand and its influence on his satisfaction. A methodology with exploring and qualifying nature has been adopted by using the analyses of content technique in interviews applied to hotel managers lebeled as having 4 and 5 stars in the State, trying to check how impression management takes place, identifying impression management tools used in relation to the physical evidences and to contacting people, as well as checking managers views in the survey about the use of impression management for client satisfaction make. The information revealed that managers, maybe for being unaware about impression management theory, haven t considered neither the physical evidences yet, nor contacting people as marketing tools. About the physical evidences, we could see that hotels take actions in a pulverized way referring to environment decoration and colors, however there isn t a global usage of physical evidences to highlight the service. Contacting people by their turn, receive better importance and attention. It was possible to make sure that managers are aware about the influence of the employee over the attendance quality. This way, we may come into a conclusion that impression management at Paraiba hotels has been under used, as long as managers seem to be, most times, turned to actions related to contacting people, not having realized the planning importance and national-wide use of service scenery in a genaral way yet

Avaliação de projetos sociais: análise da metodologia utilizada pela Petrobrás

On the aggravation of social problems and the shortage of resources, the improvement of evaluation methods and control of its application, requiring more efficiency, efficacy, effectiveness and participation in its management, has been growing. As a result, emerges the importance of studying and developing such methodologies. The overall goal of this dissertation is to know what are the difficults to incorporate the point of view of executers and beneficiaries in evaluation process. To do so, has been done a research characterized as qualitative, with a field strategy using the case study of two social projects called Petrobras Child Program, situated in the metropolitan region of Natal, and Content Analysis technique for analyze the data. The conclusions of this work can assist in improving the process of projects evaluation financed by Petrobras, contributing with its social role, besides the possibility of encouraging a greater participation of other society actors, such as beneficiaries, in the evaluation process

Processo de implantação de um sistema integrado de gestão em uma organização pública à luz da teoria da hospitalidade :um estudo de caso

In the present time, public organizations are employing more and more solutions that uses information technology in order to ofer more transparency and better services for all citizens. Integrated Systems are IT which carry in their kernel features of integration and the use of a unique database. These systems bring several benefits and face some obstacles that make their adoption difficult. The conversion to a integrated system may take years and, thus, the study of the adoption of this IT in public sector organizations become very stimulant due to some peculiarities of this sector and the features of this technology. First of all, information about the particular integrated system in study and about its process of conversion are offered. Then, the researcher designs the configuration of the conversion process aim of this study the agents envolved and the moments and the tools used to support the process in order to elaborate the methodology of the conversion process understood as the set of procedures and tools used during all the conversion process. After this, the researcher points out, together with all the members of the conversion team, the negative and positive factors during the project. Finally, these factors were analysed through the Hospitality Theory lens which, in the researcher opinion, was very useful to understand the elements, events and moments that interfered in the project. The results consolidated empirically the Hospitality Theory presumptions, showing yet a limitation of this theory in the case in study

Aplicação da metodologia numérica “fast bounds crack” para uma estimativa eficiente da evolução do tamanho de trinca

A significant part of the life of a mechanical component occurs, the crack propagation stage in fatigue. Currently, it is had several mathematical models to describe the crack growth behavior. These models are classified into two categories in terms of stress range amplitude: constant and variable. In general, these propagation models are formulated as an initial value problem, and from this, the evolution curve of the crack is obtained by applying a numerical method. This dissertation presented the application of the methodology "Fast Bounds Crack" for the establishment of upper and lower bounds functions for model evolution of crack size. The performance of this methodology was evaluated by the relative deviation and computational times, in relation to approximate numerical solutions obtained by the Runge-Kutta method of 4th explicit order (RK4). Has been reached a maximum relative deviation of 5.92% and the computational time was, for examples solved, 130,000 times more higher than achieved by the method RK4. Was performed yet an Engineering application in order to obtain an approximate numerical solution, from the arithmetic mean of the upper and lower bounds obtained in the methodology applied in this work, when you don’t know the law of evolution. The maximum relative error found in this application was 2.08% which proves the efficiency of the methodology "Fast Bounds Crack".

Aspectos do desenvolvimento da experiência docente na educação superior: um estudo sob a ótica da teoria dos gêneros de atividade

This analysis introduces results related to development of teaching experience from two professors of one Federal University who have taken part of one action of continued teacher training. We consider that the interplay among the individual, the language and the world cannot function straightly. It occurs through utterances, defined like real unit discursive communication, and genres of discourse (BAKHTIN, 1979/2011). Along the same line, the relation between the employee and his employment do not occur in a direct manner. This relationship takes place through genres of activity (CLOT, 2008/2010). As well as, a domain of speech genres has given possibility to individual an interaction with several discursive fields, a domain of activity genre allows the professional protruding in difficult situations traced in his employment. We know that the drafting for wield the teaching in the Tertiary Education is recommended by LDBEN (9394/96), which suggests that should be done in postgraduate program. In the mean time, what frequently happens an educational background based in a survey and not in the teaching. Thereby, several times we have observed difficulties in the accomplishment of teaching practice. Considering such aspects, this study seeks to comprehend the manner how the lecturers deal with the difficulties encountered in the classroom and how the years of experience have contributed or not for a domain of activity genre. In this regard, we have propped up in the development approach, introduced by Vigotsky, who asserts that the learning suitably organized results in development (VIGOTSKY, 1984/2007) and still explains the development of individual on the basis of relationship that it has with another, the social (VIGOTSKY, 1996b). For this purpose, were accomplished, by means of a snipped filmed lesson from each teacher, four sessions of self-confrontation (FAÏTA, 1996; CLOT, 2008/2010), two Simple and two Crusade, recorded in a visual format. This material was transcribed in accordance with standards from project NURC-SP (PRETI, 1999). For the analysis, we used three mains theories: of Linguistic, is mobilized the concept of speech genres (BAKHTIN) and all discursive topics (JUBRAN; FÁVERO); from Occupational Psychology, is utilized the activity genres (CLOT); from Psychology Historical-Cultural, is adopted the concept from Zone of Proximal Development and another/social in the development of individual (VIGOTSKY). In compliance with the study achieved, was possible to identify the aspects related to development of teaching experience of Tertiary Education. During the classes and reports of self-confrontation, we identify that both the professors, in the beginning of the career, they got more difficulties to deal with hindrances, and which now, with some years of experience, they get to domain better the difficult situations which they come across. They built up, for example, a greater facility in improvise examples in face of students’ difficulties in the comprehension of concepts. These aspects show that the professors have evolved the higher domain of genre, which allow them getting, in addition to turn the unexpected situation around that spring up in the professional context, as well know how to taking action in similar situation, which they have already run into in another moments. This domain enabled and enables the developing of the lecturers over the course of their professional performance.

Simulação numérica do escoamento monofásico em uma bomba centrífuga radial

Centrifugal pumps are vastly used in many industrial applications. Knowledge of how these components behave in several circumstances is crucial for the development of more efficient and, therefore, less expensive pumping installations. The combination of multiple impellers, vaned diffusers and a volute might introduce several complex flow characteristics that largely deviate from regular inviscid pump flow theory. Computational Fluid Dynamics can be very helpful to extract information about which physical phenomena are involved in such flows. In this sense, this work performs a numerical study of the flow in a two-stage centrifugal pump (Imbil ITAP 65-330/2) with a vaned diffuser and a volute. The flow in the pump is modeled using the software Ansys CFX, by means of a multi-block, transient rotor-stator technique, with structured grids for all pump parts. The simulations were performed using water and a mixture of water and glycerin as work fluids. Several viscosities were considered, in a range between 87 and 720 cP. Comparisons between experimental data obtained by Amaral (2007) and numerical head curves showed a good agreement, with an average deviation of 6.8% for water. The behavior of velocity, pressure and turbulence kinetic energy fields was evaluated for several operational conditions. In general, the results obtained by this work achieved the proposed goals and are a significant contribution to the understanding of the flow studied.

Ocratoxina A e citrinina em arroz: um estudo de metodologia para determinação simultânea de ocorrência

A ocratoxina A e a citrinina são micotoxinas encontrados naturalmente em alimentos e rações animais. A avaliação do risco do consumo de alimentos contaminados por esses compostos deve ser estimada a partir de dados confiáveis que reflitam a verdadeira concentração destas toxinas em diferentes alimentos ou insumos, especialmente se ingeridos com freqüência. Isto gera a necessidade de métodos analíticos precisos que sejam rápidos sem desconsiderar as etapas clássicas de avaliação de traços, amostragem representativa, extração, limpeza, concentração, separação de formas químicas, detecção, confirmação de identidade e quantificação. Para as micotoxinas em geral as técnicas cromatográficas são as mais aplicadas e relatadas em vista da diversidade estrutural destes compostos. Neste trabalho foi realizada uma otimização de extração utilizando o método QuEChERS modificado em comparação com os métodos Soares e Rodrigues Amaya (1989), Tanaka (2001) e Ultrassom (Palma et. al., 2007) empregando diferentes técnicas cromatográficas com detectores distintos para análise destas micotoxinas simultaneamente. Foram analisadas 38 amostras de arroz cultivadas e armazenadas em campos experimentais de Cachoeirinha na região Sul do Brasil. O uso dos sistemas CCD, HPLC-DAD e LC-MS proporcionou especificidade, precisão e sensibilidade, de modo que os limites de detecção e quantificação, obtivessem valores inferiores ao limite máximo estabelecido por órgãos reguladores internacionais (5 µg Kg-1 para ocratoxina A). Os limites de detecção encontrados para citrinina e ocratoxina A em camada delgada foram 4,7 e 6 vezes maior que para cromatografia líquida de alta eficiência acoplada a detector de arranjo de diodos, 14 e 300 vezes maior que cromatografia líquida acoplada a detector de massas. Os limites de quantificação das duas micotoxinas ficaram dentro do exigido pela legislação européia para OTA de 5 µg Kg-1 para HPLC-DAD e LC-MS. Na cromatografia de camada delgada esse valor ficou 4 vezes acima do estabelecido para ocratoxina A. A ocorrência de ocratoxina A e citrinina foi verificada em 16 % das amostras estando os teores variando entre 3 e 560 µg Kg-1, sugerindo possível exposição crônica a estas micotoxinas caso as amostras sejam consumidas.

Metodologia participativa para repositórios de recursos educacionais abertos

This research deals with the use of a participatory design methodology to develop a repository of open educational resources, the Arcaz. Discusses key aspects of neutrality and determinism of technology within the context of Social Studies of Science and Technology and presents some concepts of critical theory of technology related to the democratic construction of technological artifacts. Discusses the philosophical heritage of the movements that led to the emergence of free software, open education and open educational resources and argues that participatory design share similar ideals. It presents concepts of human-computer interaction, interaction design and user centered design, important to enhance the user experience in information systems. It addresses the participatory design as a methodology that allows the democratic participation of users in the technological construction, promoting mutual learning and active voice for the participants. Develops a participatory design methodology adapted to the Arcaz context of use and provides the procedures for the meetings conducted to apply participatory design techniques to the repository and the results obtained. It concludes with a study of some of the interventions suggested in the system and orientations for future applications of participatory practices in the development of the repository and a list of best practices, focusing on ethical principles that should guide the participatory design.
