Combinação social e construção de equipes: um estudo sobre os fatores relevantes para o processo de composição de equipes na educação executiva brasileira

A composição de equipes é um tema recorrente em diferentes áreas do conhecimento. O interesse pela definição das etapas e variáveis relevantes desse processo, considerado complexo, é manifestado por pesquisadores, profissionais e desenvolvedores de Sistemas de Informação (SI). Todavia, enquanto linhas teóricas, oriundas dos estudos organizacionais, buscam a consolidação de modelos matemáticos que reflitam a relação entre variáveis de composição de equipes e o seu desempenho, teorias emergentes, como a de Combinação Social, acrescentam novos elementos à discussão. Adicionalmente, variáveis específicas de cada contexto, que no caso dessa pesquisa é a educação executiva brasileira, também são mencionadas como tendo relevância para estruturação de grupos. Dado o interesse e a variedade de vertentes teóricas que abordam esse fenômeno, essa pesquisa foi proposta para descrever como ocorre a construção de equipes docentes e identificar as variáveis consideradas relevantes neste processo. Um modelo teórico inicial foi desenvolvido e aplicado. Dada a característica da questão de pesquisa, foi utilizada uma abordagem metodológica exploratório-descritiva, baseada em estudos de casos múltiplos, realizados em quatro instituições de ensino superior brasileiras, que oferecem cursos de educação executiva. A coleta e a análise de dados foi norteada pelos métodos propostos por Huberman e Miles (1983) e Yin (2010), compreendendo a utilização de um protocolo de estudo de caso, bem como o uso de tabelas e quadros, padronizados à luz do modelo teórico inicial. Os resultados desse trabalho indicam, majoritariamente, que: as teorias de Combinação Social e as teorias de Educação adicionam elementos que são relevantes ao entendimento do processo de composição de equipes; há variáveis não estruturadas que deixam de ser consideradas em documentos utilizados na avaliação e seleção de profissionais para equipes docentes; e há variáveis de composição que só são consideradas após o fim do primeiro ciclo de atividades das equipes. Com base nos achados empíricos, a aplicação do modelo teórico foi ajustada e apresentada. As contribuições adicionais, as reflexões, as limitações e as propostas de estudos futuros são apresentadas no capítulo de conclusões.

Construção e validação de uma escala de avaliação da consciência de carreira para a infância

Este estudo visa contribuir para a ampliação do conhecimento sobre o Desenvolvimento Vocacional na Infância, através da construção de uma escala teórica que seja capaz de avaliar a consciência de Carreira dos alunos do 1º Ciclo do Ensino Básico. As bases conceptuais para a construção do instrumento assentam nas nove dimensões do modelo teórico do Desenvolvimento de Carreira na Infância de Super (1990): curiosidade, exploração, informação, figuras de referência, interesses, locus de controlo, perspectiva de tempo, autoconceito e capacidade de planeamento. O objectivo principal desta investigação consiste na construção e validação da escala. A construção inicial da escala, incluindo a geração e o exame dos itens envolveu três peritos vocacionais da área da Psicologia, um pertencente ao Departamento de Psicologia da Universidade da Madeira e os outros, à Direcção Regional de Educação. Este estudo pressupôs uma revisão da literatura acerca do desenvolvimento vocacional na infância, procurando fazer uma análise aos modelos conceptuais com maior representatividade neste campo. Pretende dar sustentação à importância da integração progressiva desta orientação, no contexto educativo e fomentar a discussão e reflexão acerca da importância da educação para a carreira a partir da infância, nomeadamente a partir do primeiro ciclo do ensino básico, através da realização de actividades de exploração vocacional, desenvolvidas de forma transversal ao currículo escolar. Estas visam o desenvolvimento de competências de responsabilidade, autonomia, auto-estima, sociabilidade, hábitos de trabalho, planeamento do futuro e tomada de decisão, indispensáveis às escolhas conscientes e realistas.

A teoria de Callista Roy, a nanda-i e o cuidado ao paciente prostatectomizado

Trata-se de um estudo descritivo de caso clínico, com abordagem qualitativa, o qual possui como objetivo estabelecer relações entre os diagnósticos de enfermagem da NANDA-I e os problemas de adaptação segundo o Modelo Teórico de Roy em um paciente prostatectomizado. A coleta de dados ocorreu em um hospital universitário localizado na cidade de Natal-RN, no mês de janeiro de 2011, por meio de um roteiro de entrevista e exame físico. Os diagnósticos que apresentaram relações entre a NANDA-I e o Modelo de Roy foram: dor, ansiedade, constipação, sono, atividade, volume de líquido e infecção. Conclui-se que grande parte dos problemas adaptativos segundo o Modelo de Roy, manifestados pelos pacientes no pós-operatório de prostatectomia, possuem semelhança com os diagnósticos da NANDA-I

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

Fatores que influenciam a aceitação de práticas avançadas de gestão de segurança da informação: um estudo com gestores públicos estaduais no Brasil

This study examines the factors that influence public managers in the adoption of advanced practices related to Information Security Management. This research used, as the basis of assertions, Security Standard ISO 27001:2005 and theoretical model based on TAM (Technology Acceptance Model) from Venkatesh and Davis (2000). The method adopted was field research of national scope with participation of eighty public administrators from states of Brazil, all of them managers and planners of state governments. The approach was quantitative and research methods were descriptive statistics, factor analysis and multiple linear regression for data analysis. The survey results showed correlation between the constructs of the TAM model (ease of use, perceptions of value, attitude and intention to use) and agreement with the assertions made in accordance with ISO 27001, showing that these factors influence the managers in adoption of such practices. On the other independent variables of the model (organizational profile, demographic profile and managers behavior) no significant correlation was identified with the assertions of the same standard, witch means the need for expansion researches using such constructs. It is hoped that this study may contribute positively to the progress on discussions about Information Security Management, Adoption of Safety Standards and Technology Acceptance Model

Gestão colegiada da cadeia produtiva da cajucultura: o papel do comitê gestor no Rio Grande do Norte à luz do desenvolvimento regional sustentável

The theme of this dissertation is the collegiate management in the cashew cultivation s productive chain by the reading of the Managerial Committee s role in accordance with Sustainable Regional Development. The research had as aim to reveal the way as Managerial Committee s members of cashew cultivation s productive chain interpret the economic, social and environmental dimensions to the sustainability of entrepreneurships, using as interpretative base Sachs (2004) theoretical model. The theoretical reference is based in precepts of Solidarity Economy as a strategy to the Sustainable Regional Development. To reach this aim was done a case study, based in analysis of contents and semi-structured interviews with the solidarities economic entrepreneurships that integrate the Committee and with the group of Entities of Support and Fomentation responsible for formulating and conducting actions in favour of development of the chain. The research permitted to conclude that the economic, mainly, and social dimension, secondly, to super-impose the environmental dimension. The actions in favour of the chain are yet restricted and with low effectiveness when interpreted, in an integrated way, by a side, by the informers of this research and, by another side, in accordance with precepts of sustainable development

"O que é que há? O que é que está se passando" nessas cabeças? : um estudo sobre a concepção de projetos recentes da arquitetura residencial unifamiliar em Natal

L étude se fonde sur la recherche du processus inhérent à la conception du projet par le biais de l approche architecturologique proposée par Philippe Boudon et al (2000) ; un modèle théorique qui sert de fondement à la construction d une connaissance de l architecture au moyen d une étude de la nature des opérations mentales de chaque architecte lorsqu il organise son travail de conception. La modélisation de l architecturologie concentre son étude sur le travail qui a lieu avant même la confection matérielle du projet (représentation graphique finale). De cette façon, douze projets furent analysés d architecture résidencielle unifamiliale; conçus récemment par six architectes « potiguares » pour Natal et sa région périphérique. Les résultats mettent en évidence un ensemble de modèles substrats (comme point de départ) et téléologiques (comme point d arrivée) adoptés par les auteurs au cours de la conception de leurs projets. Ces modèles, de façon générale, sont liés aux pertinences socio-culturelles (conventions, formes traditionnelles ou coutumes) du contexte pour lesquels ils sont conçus (lotissements privés de co-propriété des classes moyennes et moyennes-supérieures) et en même temps, ils sont le fruit de croyances, d idéologies et d expériences antérieures propres à l espace de la conception de chaque architecte

Habitus, representações sociais e construção identitária dos professores de Maracanaú

In the last three decades, the subject of the teacher's social identity has been discussed under various theoretical focuses, not only in Brazil, but also beyond our borders. In this thesis, the theme is approached starting from the theoretical proposal that has been developed by Domingos Sobrinho (1994), which is strongly based in the epistemological approach between Pierre Bourdieu’s praxiology and the Theory of the Social Representations formulated by Serge Moscovici. It presupposes that this would make it easier to apprehend the process of construction of social identity of the investigated social group. The universe of the research is constituted by teachers of the fundamental teaching of the municipal district of Maracanaú, state of Ceará, that were active in class-room work there during at least three years, and were registered or had concluded the Course of Educational Formation promoted by UECE in that municipal district. Taking into account that the teacher's social identity is a process in permanent construction, resulting of their daily experiences and of the interferences originated from of the social context, the investigative tasks were implemented in two different stages, although they complement each other. Initially, with the objective of putting in evidence the genesis of the formation of that group’s habitus, an analysis of the family and school lives of eleven teachers who participated in the course was made, using as main sources of data: thematic memorials, semi-structured interviews and observations - inside and out of the class-room – during four school semesters. In the second stage a test of free association of words was applied to 426 teachers, seeking to apprehend the structure of the social representations of family and school – a methodological strategy considered necessary to enhance and identify certain outlines of the habitus in study, besides being in agreement with the theoretical model followed. It became evident from the results that the identity of Maracanaú’s teachers is molded and transformed into a multifaceted dynamic unit that shows successes and mistakes, certainties and doubts. For instance, besides an innovative speech seeking to reassure that teaching is a profession and not a simple vocation or mission, some discourse and attitudes are identified that point to the opposite direction, extolling the school as extension of the family, defending a parental relationship with the students, and looking at certain aspects of daily school life as “sacramental”. However, in the light of science such ambiguities and incoherences are inherent to common sense discourse, where the influences of the patterns and cultural references are present in the process of identity construction of the group, which was confirmed by the research of their social representations of family and school

Representação social do ensinar: a dimensão pedagógica do habitus professoral

Teaching is an activity inherent to the human condition. Historically, from the institutionalization of education, the key role to pursue that activity has been attributed to the teacher, who is required to adapt to the demands of each historical conjuncture. Currently, according to the new paradigmatic requirements, the teacher must possess various skills in order to handle the complex and challenging act of teaching. Assuming the existence of a gap between what the State and the scientific discourse recommend the teacher act upon in the classroom, a decision was made to identify the configuration and structure of social representation in the act of teaching, put forth by elementary school teachers in the public schools of Natal, RN, Brazil. Therefore, the research relied on the theoretical model developed by Domingos Sobrinho (1998, 2000, 2003), which articulates the praxeology of Pierre Bourdieu with the theory of social representations of Serge Moscovici (1978). It was intended to demonstrate how teachers habitus, in its due historical context, directs the construction of social representations in the act of teaching which guides the actions of the teacher, particularly in the classroom context. At the methodological level, the following methods and techniques were used: bibliographic and documentary review in order to identify the scientific discourse on the subject matter and the official parameters of educational regulation and the act of teaching; the Procedure of Multiple Classifications PMC in order to capture the configuration and structure of the representational content in focus, the direct observation of the classroom to identify in actual terms the social representation as "guide to action" as the theory preaches. From the standpoint of the analysis, quantitative data were analysed through Multidimensional Scaling MDS, covering in this study the Multidimensional Scale Analysis MSA and Smallest Space Analysis SSA; and non-parametric statiscal techniques. Additional data of qualitative value had to undergo categorical content analysis. It was then concluded that the teachers investigated guided themselves by social representation, the product of collectively constructed and shared assumptions about the act of teaching, forming a synthesis of different sources of information and knowledge acquirement, involving elements of common sense, religious habitus, pedagogic models considered outdated, the agencies responsible for teacher training and the hegemonic discourse about education today

Filtros acústicos em cristais fonônicos

In this work, we have studied the acoustic phonon wave propagation within the periodic and quasiperiodic superlattices of Fibonacci type. These structures are formed by phononic crystals, whose periodicity allows the raise of regions known as stop bands, which prevent the phonon propagation throughout the structure for specific frequency values. This phenomenon allows the construction of acoustic filters with great technological potential. Our theoretical model were based on the method of the transfer matrix, thery acoustics phonons which describes the propagation of the transverse and longitudinal modes within a unit cell, linking them with the precedent cell in the multilayer structure. The transfer matrix is built taking into account the elastic and electromagnetic boundary conditions in the superllatice interfaces, and it is related to the coupled differential equation solutions (elastic and electromagnetic) that describe each model under consideration. We investigated the piezoelectric properties of GaN and AlN the nitride semiconductors, whose properties are important to applications in the semiconductor device industry. The calculations that characterize the piezoelectric system, depend strongly on the cubic (zinc-bend) and hexagonal (wurtzite) crystal symmetries, that are described the elastic and piezoelectric tensors. The investigation of the liquid Hg (mercury), Ga (gallium) and Ar (argon) systems in static conditions also using the classical theory of elasticity. Together with the Euler s equation of fluid mechanics they one solved to the solid/liquid and the liquid/liquid interfaces to obtain and discuss several interesting physical results. In particular, the acoustical filters obtained from these structures are again presented and their features discussed

Confinamento de fónons ópticos em estruturas piezoelétricas periódicas e quasiperiódicas

We study the optical-phonon spectra in periodic and quasiperiodic (Fibonacci type) superlattices made up from III-V nitride materials (GaN and AlN) intercalated by a dielectric material (silica - SiO2). Due to the misalignments between the silica and the GaN, AlN layers that can lead to threading dislocation of densities as high as 1010 cm−1, and a significant lattice mismatch (_ 14%), the phonon dynamics is described by a coupled elastic and electromagnetic equations beyond the continuum dielectric model, stressing the importance of the piezoelectric polarization field in a strained condition. We use a transfer-matrix treatment to simplify the algebra, which would be otherwise quite complicated, allowing a neat analytical expressions for the phonon dispersion relation. Furthermore, a quantitative analysis of the localization and magnitude of the allowed band widths in the optical phonon s spectra, as well as their scale law are presented and discussed

Efeitos interfaciais em heteroestruturas quânticas nô-abruptas: GaAs/ALxGa1-xAs

Um minuncioso estudo das propriedades de confinamento em heterostructuras bidimensionais(poços quânticos) GaAs/AlxGa1_xAs, com interfaces graduais é realizado. Um modelo teórico que represente bem a variação da fração molar do alumínio nas interfaces, resultante do aparecimento de micro-rugosidades e ilhas durante os processos de crescimento e recozimento pós-crescimento da amostra, é elaborado. Vários perfis desta fração molar de alumínio nas interfaces são considerados. Soluções analíticas da equação de Schrodinger, na aproximação da massa efetiva constatne nas interfaces, resultando em equações transcendentais, que possibilitam a obtenção dos níveis de energia dos portadores, decorrentes do seu confinamento quântico, são apresentadas. Energias de ligação e de confinamento de excitons 2D, utilizando-se um método analítico e numerérico e a aproximação do potencial efetivo, são também calculadas. Resultados numéricos para os níveis de energia dos portadores e para as energias de ligação e de confinamento dos excitons 2D, em poços quânticos GaAs/Al0.35Ga0.65As não-abruptos, sem e com a presença de campo elétrico aplicado para vários perfis interfaciais da fração de molar, são mostrados. Para a obtenção desses resultados, faz-se uso do método dos degraus múltiplos e da técnica da matriz de transferência, e adota-se, como operador de energia cinética, o de Ben-Daniel e Duque para uma massa efetiva dependente da posição. Conclui-se que um modelo que leva em conta a existência de interfaces não-abruptas e seus diversos perfis é indispensável para uma melhor descrição das propriedades opto-eletrônicas de poços quânticos GaAs/AlxGa1-xAs, enquanto que a aproximação das interfaces abruptas apresenta-se bastante limitada

Espectro de Polariton de Plasmons e Ondas de Luz em Quasi-Cristais

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior

Excitações em cristais fotônicos unidimensionais

In this work, we present a theoretical study of the propagation of electromagnetic waves in multilayer structures called Photonic Crystals. For this purpose, we investigate the phonon-polariton band gaps in periodic and quasi-periodic (Fibonacci-type) multilayers made up of both positive and negative refractive index materials in the terahertz (THz) region. The behavior of the polaritonic band gaps as a function of the multilayer period is investigated systematically. We use a theoretical model based on the formalism of transfer matrix in order to simplify the algebra involved in obtaining the dispersion relation of phonon-polaritons (bulk and surface modes). We also present a quantitative analysis of the results, pointing out the distribution of the allowed polaritonic bandwidths for high Fibonacci generations, which gives good insight about their localization and power laws. We calculate the emittance spectrum of the electromagnetic radiation, in THZ frequency, normally and obliquely incident (s and p polarized modes) on a one-dimensional multilayer structure composed of positive and negative refractive index materials organized periodically and quasi-periodically. We model the negative refractive index material by a effective medium whose electric permittivity is characterized by a phonon-polariton frequency dependent dielectric function, while for the magnetic permeability we have a Drude like frequency-dependent function. Similarity to the one-dimensional photonic crystal, this layered effective medium, called polaritonic Crystals, allow us the control of the electromagnetic propagation, generating regions named polaritonic bandgap. The emittance spectra are determined by means of a well known theoretical model based on Kirchoff s second law, together with a transfer matrix formalism. Our results shows that the omnidirectional band gaps will appear in the THz regime, in a well defined interval, that are independent of polarization in periodic case as well as in quasiperiodic case
