RECIPROCIDADE ENTRE INDIVÍDUO E ORGANIZAÇÃO E SEUS IMPACTOS SOBRE A SATISFAÇÃO E O COMPROMETIMENTO

Reciprocidade indivíduo-organização e afetividade são dois fenômenos presentes na vida organizacional e que se tornaram tópicos de pesquisa no campo de estudos do comportamento organizacional. Esse estudo teve como objetivo reforçar as evidências empíricas acerca das relações entre cognições de troca indivíduo-organização e afetividade no contexto de trabalho. Para tanto, foram submetidas à teste empírico cinco hipóteses inspiradas em um estudo inédito desenvolvido por Siqueira (2002b). Contou-se com a utilização de um questionário composto por cinco escalas validadas, referentes as variáveis do estudo, que avaliaram percepção de suporte organizacional (PSO), percepção de reciprocidade organizacional (PRO), comprometimento organizacional normativo (CON), satisfação no trabalho (STR) e comprometimento organizacional afetivo (COA). Participaram 275 profissionais, sendo 183 pertencentes ao setor administrativo e 92 ao setor administrativo-acadêmico de uma Instituição de Ensino Superior, situada na região do Grande ABCD Paulista e com inserção no estado de São Paulo. OS participantes do estudo tinham idade média de 32 anos, sendo a maioria (58,2%) do sexo feminino, com escolaridade em nível superior (39,6%) e tempo médio de trabalho na organização de quatro anos. Os dados coletados foram organizados em um banco de dados eletrônico para tratamento estatístico, quando se utilizou o aplicativo SPSS (Statistical Package for the Social Scienses). Foram realizadas análises descritivas das variáveis e análises de correlação e de regressão múltipla para os testes das cinco hipóteses. Todas as hipóteses foram confirmadas. Conclui-se então, que o presente estudo reforça as proposições de Siqueira (2002b) acerca da pertinência de se considerar os três conceitos analisados (PSO, PRO E CON) como integrantes do esquema mental de reciprocidade. Ainda, os resultados do estudo reafirmam as evidências acerca da capacidade preditiva do EMR sobre satisfação no trabalho e comprometimento organizacional afetivo. Por fim, a análise dos dados aponta percepção de suporte organizacional como sendo o componente cognitivo do EMR com maior poder de influência sobre satisfação no trabalho e comprometimento organizacional afetivo. Portanto, cognições acerca das relações de troca social com organizações antecedem satisfação e comprometimento afetivo que, por sua vez, são importantes fatores a favor da organização, contribuindo para sua efetividade.

TV DIGITAL INTERATIVA NO BRASIL: ESTUDO DOS APLICATIVOS INTERATIVOS STICKERCENTER E DO TELEJORNAL MGTV

Com o avanço da tecnologia e chegada da TV digital no Brasil, estudos apontam que a televisão aberta começa um novo estágio desde seu surgimento. Esta mídia disponibiliza ferramentas que permitem aos emissores de conteúdo uma dimensão interativa ainda não experimentada, sobretudo nos processos de comunicação massivos indicando que é possível novos caminhos de investimento na produção de conteúdo por parte das emissoras de TV. Com esta realidade de fundo, experiências começam a ser testadas no âmbito da televisão, como o StickerCenter, um software - desenvolvido pela TOTVS - que reúne elementos da internet na TV possibilitando ao receptor maior interação com o conteúdo televisivo, outra experiência é a realizada pela Rede Integração, afiliada à Rede Globo em Minas Gerais, com o software desenvolvido pela HXD Interactive Television, que testa um modelo brasileiro de interatividade no telejornal. Este trabalho mostra como estas duas empresas estão desenvolvendo aplicativos interativos para a TV utilizando o Middleware Ginga e os motivos pelos quais sua popularização não aconteceu. O StickerCenter não se popularizou e indica que o motivo seja erro de estratégia da empresa em desenvolver um produto que une broadband e broadcast TV sem atrativos ao consumidor, já o aplicativo interativo da Rede Integração não foi colocado no ar e apresenta inúmeros fatores que demonstram que não explorará a interatividade pela ausência de canal de retorno. Este estudo investigou o impacto da interatividade no mercado da radiodifusão e como a convergência tecnológica aponta para a construção de uma nova mídia baseada em displays interativos capazes de oferecer aos consumidores uma nova forma de recepção de conteúdo.

Análise numérica de dutos enterrados sujeitos a elevação e recalque localizado

Problems associated to longitudinal interactions in buried pipelines are characterized as three-dimensional and can lead to different soil-pipe issues. Despite the progress achieved in research on buried pipelines, little attention has been given to the three-dimensional nature of the problem throughout the last decades. Most of researches simplify the problem by considering it in plane strain condition. This dissertation aims to present a study on the behavior of buried pipelines under local settlement or elevation, using three-dimensional simulations. Finite element code Plaxis 3D was used for the simulations. Particular aspects of the numerical modeling were evaluated and parametric analyzes were performed, was investigated the effects of soil arching in three-dimensional form. The main variables investigated were as follows: relative density, displacement of the elevation or settlement zone, elevated zone size, height of soil cover and pipe diameter/thickness ratio. The simulations were performed in two stages. The first stage was involved the validation of the numerical analysis using the physical models put forward by Costa (2005). In the second stage, numerical analyzes of a full-scale pipeline subjected to a localized elevation were performed. The obtained results allowed a detailed evaluation of the redistribution of stresses in the soil mass and the deflections along the pipe. It was observed the reduction of stresses in the soil mass and pipe deflections when the height of soil cover was decreased on regions of the pipe subjected to elevation. It was also shown for the analyzed situation that longitudinal thrusts were higher than vi circumferential trusts and exceeded the allowable stresses and deflections. Furthermore, the benefits of minimizing stress with technical as the false trench, compressible cradle and a combination of both applied to the simulated pipeline were verified

Modelagem e simulação da solubilidade de sais em sistemas aquosos com Monoetilenoglicol

Primary processing of natural gas platforms as Mexilhão Field (PMXL-1 ) in the Santos Basin, where monoethylene glycol (MEG) has been used to inhibit the formation of hydrates, present operational problems caused by salt scale in the recovery unit of MEG. Bibliographic search and data analysis of salt solubility in mixed solvents, namely water and MEG, indicate that experimental reports are available to a relatively restricted number of ionic species present in the produced water, such as NaCl and KCl. The aim of this study was to develop a method for calculating of salt solubilities in mixed solvent mixtures, in explantion, NaCl or KCl in aqueous mixtures of MEG. The method of calculating extend the Pitzer model, with the approach Lorimer, for aqueous systems containing a salt and another solvent (MEG). Python language in the Integrated Development Environment (IDE) Eclipse was used in the creation of the computational applications. The results indicate the feasibility of the proposed calculation method for a systematic series of salt (NaCl or KCl) solubility data in aqueous mixtures of MEG at various temperatures. Moreover, the application of the developed tool in Python has proven to be suitable for parameter estimation and simulation purposes

Elaboração de ferramenta computacional para aprendizado da anatomia do pescoço

The teaching-learning process requires a constant search on the part of educators for didatic innovations aimed at improving learning. Among these are technological innovations our students are familiar with. In human anatomy teaching, these innovations are increasingly important, since the need for “mechanizing” many structures may make learning tiresome and nonstimulating for students. The search for new technologies may make this process simpler. Another important issue is the need to constantly emphasize applying the knowledge in question, in order for students to better understand the meaning of learning. Accordingly, this project aims to develop an interactive tablet application for neck anatomy. This application will function as a guide to dissection, containing text, photographs, drawings and videos, distributed systematically, with a script emphasizing the clinical and surgical importance of neck anatomy.

Ostomy is an open surgical origin, when it is necessary to deviate temporarily or permanently, the normal transit of food and / or deletions. The patient with ostomy disposal is faced with changes in their physiology, also emerging on the need to care collection bag. This study aimed to analyze the quality of life (QOL) of people living with ostomy Intestinal (EI), who attended the Pediatric and Adult Rehabilitation Center of Rio Grande do Norte (CRI / CRA-RN). It is an analytical study with cross-sectional design and quantitative approach, accomplished with 89 people who had EI. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (CEP / UFRN), CAAE: 19866413.3.0000.5537. Held data collection in the period January-March 2015 using two instruments: an adapted general questionnaire covering socio-demographic, clinical and self-care and a specific instrument for assessing QOL of people with stoma titled as City of Hope Quality of Life - Ostomy Questionnaire (COH-QOL-Q), validated and adapted to Portuguese in 2010, composed of four areas, namely: Welfare Body (BEF), Welfare Psychological (BEP), Welfare (BES ) and Spiritual Well-Being (BEE). The collected data were entered into a database in Microsoft Excel 2007 spreadsheet application and processed in computerized software for descriptive and inferential analysis. The results showed that 83.1% had a colostomy and ileostomy 16.9%. Sociodemographic characteristics prevailed in males (57.3%), over 50 (57.3%), mulatto (46.1%), with presence of companion / a (57.3%), retired / beneficiaries (50.5%), monthly income above the minimum wage (68.5%) and who have studied up to elementary school (67.4%). Regarding clinical aspects, it was observed that the main cause that led to the making of the stoma was the neoplasm (59.6%) followed by trauma (21.3%). The sample showed people with stoma for more than six months (79.8%) of permanently (57.3%), in use sink equipment piece drainable (68.5%) of flat base (82.0%). With respect to self-care, 93.3% emptied and washed the bag alone (care related to hygiene) and 75.3% fixed the new exchange on the skin during the exchange (care related to the stock). Patients with more than six months of ostomy and had no partner (a) had higher averages of self-care related hygiene and purse. The average of respondents QoL scores was 68.90% for General QOL; 68.03% for the BEF; 68.38% for the BEP; 66.46% for BES and 75.41% for BEE. Among the aspects that influenced QOL included: physical strength, pain, suffering and gases (physical domain); appearance, care of the stoma and adaptation to new condition (psychological domain); isolation, interference in personal relationships and social activities (social domain) and going to church or synagogue, spiritual activities and positive change after ostomy (spiritual realm). Based on these results, it is concluded that this was a predominantly adult sample / elderly (between 50 and 70 years), with low education and the cause motivating the stoma, neoplasms. However, such findings did not pass at low percentage levels on the self-care capacity to deliver even at low QOL scores.

Proposta de método para avaliação do desempenho térmico de residências unifamiliares em clima quente e úmido

Nowadays, evaluation methods to measure thermal performance of buildings have been developed in order to improve thermal comfort in buildings and reduce the use of energy with active cooling and heating systems. However, in developed countries, the criteria used in rating systems to asses the thermal and energy performance of buildings have demonstrated some limitations when applied to naturally ventilated building in tropical climates. The present research has as its main objective to propose a method to evaluate the thermal performance of low-rise residential buildings in warm humid climates, through computational simulation. The method was developed in order to conceive a suitable rating system for the athermal performance assessment of such buildings using as criteria the indoor air temperature and a thermal comfort adaptive model. The research made use of the software VisualDOE 4.1 in two simulations runs of a base case modeled for two basic types of occupancies: living room and bedroom. In the first simulation run, sensitive analyses were made to identify the variables with the higher impact over the cases´ thermal performance. Besides that, the results also allowed the formulation of design recommendations to warm humid climates toward an improvement on the thermal performance of residential building in similar situations. The results of the second simulation run was used to identify the named Thermal Performance Spectrum (TPS) of both occupancies types, which reflect the variations on the thermal performance considering the local climate, building typology, chosen construction material and studied occupancies. This analysis generates an index named IDTR Thermal Performance Resultant Index, which was configured as a thermal performance rating system. It correlates the thermal performance with the number of hours that the indoor air temperature was on each of the six thermal comfort bands pre-defined that received weights to measure the discomfort intensity. The use of this rating system showed to be appropriated when used in one of the simulated cases, presenting advantages in relation to other evaluation methods and becoming a tool for the understanding of building thermal behavior

Uma metodologia heurística para minimizar o roteiro nos serviços de leitura de hidrômetros

Este trabalho tem por objetivo propor uma metodologia heurística para o Problema de Cobertura de Arcos aplicado aos serviços de saneamento, em específico na leitura de hidrômetros. Dentro deste contexto desenvolveu-se um aplicativo que permite o planejamento de rotas de maneira que os custos em distância percorrida sejam reduzidos e mantenham-se aproximadamente os mesmos em todos os percursos. A metodologia foi dividida em etapas. Na primeira etapa, para compreender melhor o problema, fez-se uma pesquisa de campo organizando os dados disponibilizados por uma empresa de saneamento. A segunda etapa foi caracterizada pela determinação de pontos em cada metade de trechos de quadra e nas interseções de ruas, os quais foram cadastrados, em um mapa georeferenciado. Este mapa contemplou a região escolhida para o estudo e os pontos cadastrados serviram para determinar e consequentemente, designar as medianas relacionadas, o que constitui a terceira etapa. Para isso utilizou-se respectivamente o algoritmo de Teitz Bart Modificado por CADP e o algoritmo de designação de Gillet e Johnson adaptado. Ao final desta etapa formaram-se subsetores dentro de um setor específico. Na última etapa encontrou-se as rotas de cada subsetor através do algoritmo genético. O aplicativo desenvolvido permitiu flexibilidade de ações, dando autonomia para o usuário na escolha das opções de cálculo. Sua interface gráfica possibilitou a elaboração de mapas e a visualização das rotas em cada subsetor. Além disso o aplicativo minimizou os percursos e distribuiu os subsetores com distâncias aproximadas. A eficiência das heurísticas que embasaram o aplicativo desenvolvido, foi comprovada através dos testes realizados, os quais obtiveram resultados de boa qualidade.
