Especificamente, examinou que fatores relacionados ao trabalho e n?o-trabalho s?o preditores da inten??o de continuar trabalhando, explorando ainda, se significados da aposentadoria vinculam-se ? essa decis?o. A pesquisa, de corte transversal e com desenho de m?todos mistos incorporados, abrangeu 283 servidores de uma universidade federal do Nordeste que se encontravam pr?ximos ? aposentadoria. Envolveu a aplica??o de um question?rio on line, composto por quest?es abertas e pela escala Older Worker?s Intention to Continue Working (OWICW) de Shacklock e Brunetto (2011), que inicialmente foi submetida ? adapta??o transcultural. Os dados quantitativos foram submetidos a an?lises descritivas e multivariadas, sendo especificamente calculadas diferen?as entre m?dias e coeficientes de regress?o log?stica m?ltipla. Os dados textuais foram analisados utilizando a t?cnica lexicogr?fica de Classifica??o Hier?rquica Descendente. Os resultados revelaram que a maioria dos participantes querem continuar no trabalho remunerado, sendo preditores dessa inten??o a percep??o de autonomia pessoal no trabalho, a intera??o interpessoal no trabalho, interesses fora do trabalho, e condi??es flex?veis de trabalho. Quanto ? decis?o de adiar a aposentadoria e permanecer na organiza??o, s?o fatores preditivos a autonomia pessoal, condi??es flex?veis de trabalho, e o incentivo financeiro (abono de perman?ncia). A an?lise textual revelou a exist?ncia de cinco padr?es de significados de aposentadoria: direito do trabalhador, descanso, ficar em casa ocioso, nova etapa de vida, tempo de usufruir a vida. A decis?o de adiamento est? vinculada ? aposentadoria como ociosidade e aus?ncia de atividades substitutivas ao trabalho, e a decis?o de parar o trabalho vinculada ? aposentadoria como uma vida com mais qualidade. O estudo propicia informa??es que podem subsidiar pol?ticas de gest?o diante do processo de decis?o trabalho-aposentadoria. / This study investigated the intention of the older workers to continue working after state pension age/time. On this way, it explores the relation between this intention and factors related with the meanings of the work and retirement. Specifically, it was examined that factors related to work and non-work are predictors of the intention to continue working, and it was explored if meanings of retirement are linked to this decision. It is a crosssectional mixed methods study, using a survey conducted with 283 federal civil servants of a federal Northeastern University which were near retirement. It envolved an on-line questionnaire, with open-ended questions and the likert-type scale "Older Worker's Intention to Continue Working" (OWICW) of Shacklock and Brunneto (2011), which was validated to the Brazilian version. The quantitative data were analyzed using descriptive and multivariate statistics, specifically procedures for comparing means and coefficients of multiple logistic regression. The qualitative data were analyzed using the lexicographical technique Descending Hierarchical Classification. The findings indicate that most participants want to continue in paid work, and that perception of personal autonomy at work, interpersonal relationships at work, interests outside of work, and flexible working arrangements are significant predictors of intention to continue working. Furthermore, the perception of personal autonomy at work, flexible working arrangements, and the financial incentives are predictors of decision to postpone retirement and remain in the organization. The analysis revealed five patterns of meanings of retirement: "worker's right", "resting", "idle time at home", "new stage in the life course", and "enjoy the use of time?. The decision to postpone retirement is linked to idleness and lack of substitutionary activities work, and the decision to stop working linked to retirement as a life with more quality. The study provides information that can contribute with management policies before the process of retirement decision.

Do ponto de vista te?rico e pr?tico, estudou que lugar ocupa a ATD para resolu??o de ocorr?ncias que demandam o uso da for?a e/ou armas de fogo na atividade profissional de Cabos e Sargentos da PMRN. Procurou caracterizar os fatores que influenciam no processo da atividade em quest?o, discutindo, ainda, a Tomada de Decis?o no contexto da forma??o inicial e continuada. Al?m de refletir e interpretar os dados emp?ricos, a Tese, tamb?m, prop?e um referencial procedimental para potencializar o processo de Tomada de Decis?o em ocorr?ncias policiais cr?ticas. De natureza explorat?ria e descritiva, a pesquisa foi desenvolvida em mar?o de 2016, no Centro de Forma??o e Aperfei?oamento da Pol?cia Militar do Rio Grande do Norte (CFAPM), em Natal, inquirindo 23 Cabos e 34 Sargentos, em processo de forma??o continuada, onde, por meio de um question?rio misto, buscou desvelar a partir de um caso hipot?tico, que simulou uma ocorr?ncia cr?tica, com uma v?tima sob amea?a iminente de morte, que medidas imediatas da ATD seriam tomadas por esses policiais. Os resultados da pesquisa apontam para duas forma??es diferenciadas por se tratarem de categorias de n?veis diferentes, contudo, h? de se considerar as responsabilidades equivalentes no desempenho do policiamento ostensivo, cotidiano, mobilizando conhecimentos e saberes similares. Os Sargentos com uma m?dia de 30 anos de servi?o tiveram uma forma??o dentro do paradigma militarista, enquanto a dos Cabos foi embasada nas Bases Curriculares para os Profissionais de Seguran?a do Cidad?o, institucionalizadas pelo Minist?rio da Justi?a (MJ), por meio da Secretaria Nacional de Seguran?a P?blica (SENASP) a partir de 2000. Em que pese n?o haver um protocolo nacional e/ou estadual para nortear ? ATD dos policiais militares em ocorr?ncias cr?ticas, os resultados apontam para uma padroniza??o das a??es imediatas adotadas pelos informantes da pesquisa, a partir da doutrina de gerenciamento de crises, sistematizada por meio de curso da Rede EaD da SENASP/MJ. Evidenciou-se ainda maior autonomia profissional em conhecimentos e saberes nesse campo de estudos, por parte dos Cabos, que apresentam, tamb?m, maior n?vel de escolariza??o. No contexto institucional, apesar das pol?ticas implementadas no pa?s no ?mbito da seguran?a p?blica, sobressai-se a vis?o de que a forma??o ? muito mais protocolar do que voltada para atender ?s necessidades formativas da pr?tica profissional. / The thesis is about Decision Making Activity (DMA) as a professional knowledge that composes the educational training process of the Military Police. From a theoretical and practical perspective, it has been studied the role taken by ATD as a way to solve criminal activity incidents that demand the use of force and/or guns in the ordinary procedures performed by Cables and Sergeants of the PMRN while on duty. It aimed to characterize the factors that influence the process of the mentioned activity, also discussing the Decision Making in the context of initial and continuing training. In addition to reflecting and interpreting the empirical data, the thesis also proposes a procedural framework to enhance the decision-making process in critical crime incidents. Exploratory and descriptive, this survey was carried out in March 2016, at the Center for Training and Improvement of the Rio Grande do Norte Military Police (CFAPM), in Natal, inquiring 23 Cables and 34 Sergeants, in a process of continuous education, where, through a mixed questionnaire, it aimed to reveal ? from a hypothetical case, which simulated a critical crime incident, whereas a victim was under imminent death threat ? what immediate DMA measures would be taken by those police officers. The results collected from that survey point to two differentiated types of training, because they belong to different hierarchy levels under a Chain of Command, however, equal responsibilities must be considered in the performance of ostensible, everyday policing, mobilizing similar knowledge and skills. The sergeants with an average of 30 years of service had an training within the militaristic paradigms, whereas that one of the Cables? was established in the Curriculum Bases for the Citizen Security Professionals, institutionalized by the Ministry of Justice (MJ), through the National Board of Public Security (SENASP) since the year 2000. In spite of the lack of a national and/or state protocol to guide the DMA of military police officers in critical incidents, the results point to a standardization of the immediate actions adopted by those subject to the previously mentioned survey, based upon the crisis management doctrine, also systematized through a course from SENASP/MJ Distance Education Network. An even greater professional autonomy has been highlighted concerning the knowledge and skills in that area of study, presented by the Cables in the survey, who also demonstrated a higher level of schooling. In the institutional context, despite the policies implemented in the country in the area of public security, it stands out the perception that the police training is much more a protocol than directed to meet the standards of professional practice training.

Tamb?m investigamos, medindo o tempo de perman?ncia em cada ?rea, a influ?ncia do aprendizado no desempenho das oper?rias ao longo de sucessivas viagens. Foram simulados quatro cen?rios. Cada oper?ria realizou 10 viagens em cada cen?rio. Cen?rio 1: oper?rias sempre encontravam alimento de alta qualidade; Cen?rio 2: oper?rias encontravam alimento de alta qualidade em somente 50% das viagens; Cen?rio 3: oper?rias encontravam alimento de alta e baixa qualidade com probabilidades de ocorr?ncia de 0,5 para cada tamanho de alimento. Cen?rio 4: oper?rias tinham tr?s possibilidades, encontrar alimento de alta qualidade (33%), encontrar alimento de baixa qualidade (33%) e n?o encontrar alimento. Em todos os cen?rios, havia duas rotas poss?veis de explora??o, uma com 300 cm e outra com 600 cm de comprimento. A pesquisa mostrou que oper?rias da esp?cie D. quadr?ceps tendem a retornar ao mesmo local onde o alimento foi encontrado na viagem anterior, n?o importando a dist?ncia, tamanho do alimento ou taxa de recompensa. Nos casos de viagens sem captura, oper?rias eram mais propensas a trocar de ?rea em busca de alimento. No entanto, no cen?rio 4 essa decis?o de ?troca? foi menos evidente, possivelmente pela maior din?mica do cen?rio. Resultados tamb?m indicaram um processo de aprendizado das rotas de explora??o assim como das condi??es das ?reas de explora??o. Com a repeti??o das viagens, forrageadoras reduziram o tempo de busca nas ?reas nas viagens que n?o capturavam alimento e rapidamente trocavam de ?rea. / When searching for food, animals often make decisions of where to go, how long to stay in a foraging area and whether or not to return to the last visited spot. These decisions can be enhanced by cognitive traits and adjusted based on previous experience. In social insects such as ants, foraging efficiency have an impact on both individual and colony level. The present study investigated, in the laboratory, the effect of distance from food, capture success and food size, and reward rate on decisions of where to forage in Dinoponera quadriceps, a ponerine ant that forage solitarily and individually make their foraging decisions. We also investigated the influence of learning on the performance of workers over successive trips searching for food by measuring the patch residence time in each foraging trip. Four scenarios were created differing in food reward rates, food size offered and distances colony-food site. Our work has shown that as a rule-of-thumb, workers of D. quadriceps return to the place where a prey item was found on the previous trip, regardless of distance, food size and reward rate. When ants did not capture preys, they were more likely to change path to search for food. However, in one of the scenarios, this decision to switch paths when unsuccessful was less evident, possibly due to the greater variation of possible outcomes ants could experience in this scenario and cognitive constraints of D. quadriceps to predict variations of food distribution. Our results also indicated a learning process of routes of exploration as well as the food site conditions for exploration. After repeated trips, foragers reduced the patch residence time in areas that they did not capture food and quickly changed of foraging area, increasing their foraging efficiency.

In the present study, I investigated the relationship between theta power and choice selection during spatial decision-making. I recorded local field potentials from the CA1 region of rats retrieving reward locations in a 4-arm maze. In trained but not in na?ve animals, I observed a significant increase in theta power during decision-making, which could not be explained by changes in locomotion speed. Furthermore, a Bayesian decoder based on theta power predicted choice outcomes in speed-matched trials. The decoding time course revealed that performance increased above chance before the decision moment exclusively for theta power, remaining flat for other frequency bands. These results occurred for trained animals, but no significant prediction could be made for na?ve animals. Altogether, the data support a mnemonic function of theta rhythm during spatial decision-making, indicating that these oscillations correlate with the retrieval of memories required for successful decisions / O hipocampo ? uma estrutura essencial para o processamento de mem?rias espaciais e epis?dicas.

One of the impacts caused by these changes is observed in decision-making, one of the components of executive functioning. In the context of emergency care in health work, decision making becomes one of the most important elements, because although most decisions can be resolved with a prepared team, the unpredictability scenario and the severity of interventions exposes the medical team to a constant stress, which can impair activities such as plan appropriate responses. This study aimed to assess the relationship between sleep and decision making in 26 medical technicians of the emergency care units undergoing shifts schemes and to translate and adapt to Portuguese decision-making hypothetical scenarios based on Policy-Capturing Technique. To sleep evaluation, we used the Pittsburgh Sleep Quality Index (PSQI), the Sleep Habits Questionnaire, the Epworth Sleepiness Scale and Chronotype Identification Questionnaire Horne-Ostberg. To evaluate the decision-making, was used the Iowa Gambling Task (IGT) and hypothetical scenarios created according to the Policy-Capturing Technique, which were translated into Portuguese and adapted according to the needs of our sample. For inclusion / exclusion criteria, the participants answered the Chalder Fatigue Scale, the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI) and the Inventory of Stress Symptoms for adults of Lipp (ISSL). Participants were divided into day shift (N = 6) and alternating shift (N = 20). The results showed a good sleep quality for physicians of the day shift and poor sleep quality for the alternating shift. A good quality sleep and less somnolence were correlated with better performance in decision-making. An assessment was made in order to verify the relationship between the two decision-making protocols and the results showed a correlation between them, indicating worse decision-making evaluated by IGT related to losses in decision making evaluated by the scenarios. It was found impaired decision making when measured along the shift. It is concluded that the scheme of alternating shift work can be detrimental to the sleep quality of doctors and a good sleep quality can contribute to a better performance in decision-making.

Pesquisa do Estado do Rio Grande do Sul (FAPERGS) / There is relative consensus that low level and quality of education are limiting factors of a country?s growth. Statistics show that many students have difficulties in learning or do not display the necessary abilities to succeed academically. Trying to reduce such difficulties, neuropsychology has developed remediation and rehabilitation interventions. There is, however, a need to invest in intervention programs that promote cognitive health and stimulate neurocognitive skills among children. These programs may potentiate cognitive processes and lead to short and long term benefits. Evidence shows that the executive functions (EF) have a crucial role in education, and are relevant in learning and in autoregulatory behavior. Given this context, the objective of this thesis was to develop and verify the effectiveness of an early and preventive neuropsychological intervention program with the intent of stimulating the EF among Elementary School students. The program was called Program of Neuropsychological Stimulation of Cognition in Students: emphasis on Executive Functions, or PENcE (an acronym from its original name in Portuguese, Programa de Estimula??o Neuropsicol?gica da Cogni??o em Escolares: ?nfase nas Fun??es Executivas). The First Study performed a systematic review of empirical studies about neuropsychological interventions of EF among children with typical development, looking for an overview that could guide the construction of the PENcE. Nineteen studies were found through the PRISMA method: most of them provided evidences that the children who participated in the intervention programs improved their executive functions. For the most part, they used computerized cognitive training to stimulate working memory. Other studies proposed a curricular approach to potentiate autoregulation. It was possible to observe that the studies are very heterogenic in terms of approach, methods, and closing measurement tools. Computerized trainings seem improve trained cognitive skills, but are limited in terms of transferring gains. Curricular programs seem more generalizable, with effects on transferring gains and functionality. The objective of the Second Study was to present the process of construction and content validity evidences for the PENcE. There were four steps involved in reaching that goal: internal stage of program organization; program construction; analysis by expert judges; and data integration and program finalization. All stages were important and contributed to improve the program. Furthermore, the assessment of the program (global and of each module) presented a level of agreement among judges equal to one, allowing for the achievement of content validity evidences. Finally, the Third Study investigated the effectiveness of the PENcE among children attending 3rd and 4th grades of Elementary School. It also analyzed the effects of transferring to other skills (executive, cognitive, academic, behavioral) beyond the main executive closings. From an initial sample of 160 children, 113 participated in the study. They were divided into two groups: experimental group (EG) (n=64) and control group (CG) (n=49). There were no differences between the groups before the intervention. After the study, the groups were compared, and the EG presented significant gains in inhibitory control, working memory, and abstract planning. There were transferring effects to other cognitive abilities (such as attention and fluid thinking), academic abilities (math and written skills), and changes in behavior (relationship and behavioral problems), and the overcame the CG. As a group, the findings from the three studies offer an early and preventive intervention program that has theoretical basis, has followed a rigorous construction process, and possesses content validity and effectiveness analysis. For future studies, it is suggested to extend and adapt the program to other age groups and to children who already present executive deficits, including learning difficulties and ADHD. Moreover, with the goal of contributing to public policies, it is recommended that the PENcE be implemented in public schools in developing countries, helping to bridge the gap between neuropsychology and education in a practical way. / Atualmente, h? relativo consenso de que o baixo n?vel educacional e a reduzida qualidade do processo de escolariza??o s?o fatores limitadores de crescimento de um pa?s. Al?m disso, as estimativas mostram que um elevado n?mero de alunos apresenta dificuldades de aprendizagem ou n?o apresenta habilidades necess?rias para ter sucesso acad?mico. Na tentativa de contribuir com a diminui??o de tais dificuldades, a neuropsicologia desenvolveu predominantemente interven??es de remedia??o e de reabilita??o. Destaca-se, contudo, a necessidade de se investir em programas de interven??es de promo??o ? sa?de cognitiva e de estimula??o de habilidades neurocognitivas em crian?as, uma vez que tais programas podem potencializar os processos cognitivos e levar a benef?cios de curto a longo prazo. Com o avan?o da neuropsicologia, h? evid?ncias de que as fun??es executivas (FE) t?m um papel crucial na educa??o e s?o relevantes para aprendizagem e comportamento autorregulat?rio. Frente a esse contexto, essa tese teve como objetivo desenvolver e verificar a efetividade de um programa de interven??o neuropsicol?gica precoce-preventiva em busca da estimula??o das FE em escolares no Ensino Fundamental I. Tal programa foi denominado Programa de Estimula??o Neuropsicol?gica da Cogni??o em Escolares: ?nfase nas fun??es executivas (PENcE). No primeiro estudo, a partir de uma revis?o sistem?tica, buscou-se caracterizar os estudos emp?ricos sobre interven??es neuropsicol?gicas de FE em crian?as com desenvolvimento t?pico, em busca de um panorama que norteasse a constru??o do PENcE. Seguindo o m?todo PRISMA, foram encontrados 19 estudos e a maioria forneceu evid?ncias que as crian?as que participaram dos programas de interven??o melhoraram suas habilidades executivas. A maioria utilizou o treino cognitivo computadorizado, envolvendo a estimula??o da mem?ria de trabalho. Outros propuseram uma abordagem curricular com intuito de potencializar a autorregula??o. Foi poss?vel verificar que os estudos s?o bastante heterog?neos em rela??o a tipos de abordagem, m?todos e instrumentos de medida de desfecho. Contudo, os treinos computadorizados parecem levar a uma melhora na habilidade cognitiva treinada, por?m, s?o limitados em termos de transfer?ncia de ganhos. Os programas de abordagem curricular, por sua vez, parecem mais generaliz?veis, com efeito de transfer?ncia e ganho na funcionalidade. No Estudo 2, objetivou-se apresentar o processo de constru??o e evid?ncias de validade de conte?do do PENcE. Para isso, quatro etapas foram realizadas: fase interna de organiza??o do programa; constru??o do programa; an?lise de ju?zes especialistas; integra??o dos dados e finaliza??o do programa. Todas as etapas foram essenciais e contribu?ram para aprimorar o programa. Al?m disso, evidenciou-se que a avalia??o global do programa e de cada um dos m?dulos apresentou um n?vel de concord?ncia de 1,0 entre os ju?zes, permitindo obter evid?ncias de validade de conte?do. Por fim, no Estudo 3 buscou-se investigar a efetividade do PENcE em crian?as do 3? ou 4? ano do Ensino Fundamental, bem como, analisar o efeito de transfer?ncia para outras habilidades executivas e cognitivas, habilidades acad?micas e comportamento, para al?m dos desfechos executivos principais. De uma amostra inicial de 160 crian?as, 113 participaram do estudo e foram subdivididas em dois grupos: grupo experimental (GE) (n=64) e grupo controle (GC) (n=49). Os grupos n?o se diferenciaram em nenhuma medida na avalia??o pr?-interven??o. Na compara??o dos grupos, verificou-se o GE apresentou ganhos significativos de controle inibit?rio, mem?ria de trabalho, planejamento abstrato. Houve efeito de transfer?ncia para outras habilidades cognitivas (como aten??o e racioc?nio fluido), habilidades acad?micas (matem?tica e escrita) e mudan?a no comportamento (relacionamento e problemas de conduta), sendo que o GE superou o GC. Em conjunto, os achados dos tr?s estudos contribuem disponibilizando um programa de interven??o precoce-preventiva, que possui embasamento te?rico, que seguiu um rigoroso processo de constru??o e que denota de validade de conte?do e de an?lise de efetividade. Sugere-se, para os pr?ximos estudos, estender e adaptar o programa para outras faixas et?rias e para grupos de crian?as que j? apresentam d?ficits executivos, como com transtornos espec?ficos de aprendizagem e TDAH. Al?m disso, visando a contribuir com as pol?ticas p?blicas, recomenda-se que o PENcE possa ser implementado em escolas p?blicas nos pa?ses em desenvolvimento, rumo a uma interface cada vez mais pr?tica entre neuropsicologia e educa??o.

In this scenario, investors seek to organize themselves through Investment Funds, require the definition of policies and regulations, and hire experienced Managers who can achieve a better performance for their equity. Given the criticality of this Management, whether due to its effect on investors' equity or through the propagation of mistaken analyzes about the economy, it implies the need to understand better how the decision-making of these Managers is, in fact, structured in real contexts. From this perspective, the objective of this work is to characterize the decisionmaking of the Managers of Investment Funds in Variable Income in the perspective of the naturalistic decision. This research presents a qualitative study with 13 Managers of Investment Funds in Variable Income that manage 31 Investment Funds. In addition to exploratory interviews and analysis of documents of approximation with the field of study, the RPD (recognition-primed decision) model was used based on episodic interviews through the CDM (critical decision method) protocol to elicit knowledge about manager?s critical decision activities, which are the allocation and management of the portfolio. The results suggest that the management of the Investment Fund does not obey the order of the choices and the Manager's expertise and intuition plays a decisive role in the construction of investment strategies. The data also show that there are significant differences between novice managers and experts who impact on performance, being the expert defined by the repertoires of acquired standards and their model of mental simulations practiced. It was also explored that self-regulation and self-efficacy constructs may explain differences in performance over time. Finally, research contributions and limitations are presented. / As decis?es de investimento financeiro s?o din?micas e complexas pois s?o orientadas por uma s?rie de fatores, tais como, o contexto macroecon?mico, a volatilidade dos mercados e o risco potencial de perda financeira, que impactam o valor dos ativos. Nesse cen?rio, os investidores buscam se organizar atrav?s de Fundos de Investimento, exigem a defini??o de pol?ticas e regulamentos, e contratam Gestores experientes que consigam obter um melhor desempenho para seu patrim?nio. Tendo em vista a criticidade dessa Gest?o, quer seja por seu efeito sobre o patrim?nio dos investidores, quer seja pela propaga??o de an?lises equivocadas sobre a economia, implica na necessidade de se compreender melhor como a tomada de decis?o desses Gestores ?, de fato, estruturada em contextos reais. Sob essa ?tica, o objetivo desse trabalho ? caracterizar a tomada de decis?o dos Gestores de Fundos de Investimento em Renda Vari?vel na perspectiva da decis?o natural?stica. Esta pesquisa apresenta um estudo qualitativo com 13 Gestores de Fundos de Investimento em Renda Vari?vel que administram 31 Fundos de Investimento. Al?m de entrevistas explorat?rias e an?lise de documentos de aproxima??o com o campo de estudo, foi utilizado o modelo RPD (recognition-primed decision) com base em entrevistas epis?dicas atrav?s do protocolo CDM (critical decision method) para elicitar conhecimento sobre as atividades cr?ticas de decis?o dos Gestores que s?o a aloca??o e a gest?o do portfolio. Os resultados sugerem que a gest?o de Fundo de Investimento n?o obedece a ordem das escolhas e a expertise e a intui??o do Gestor possui um papel determinante na constru??o de estrat?gias de investimento. Os dados demonstram ainda que existem diferen?as relevantes entre Gestores novatos e peritos que impactam no desempenho, sendo o perito definido pelos repert?rios de padr?es adquiridos e seu modelo de simula??es mentais praticadas. Explorou-se tamb?m que os construtos de auto-regula??o e auto-efic?cia podem explicar diferen?as entre o desempenho ao longo do tempo. Por fim, contribui??es e limita??es da pesquisa s?o apresentadas.

In the other hand, nowadays reality shows, not only in terms of access to education but also by one s free choice, that the graduated professions aren t the only way to achieve stability and professional satisfaction. Job market needs professional with other kinds of qualifications. The main goal of this research was to evaluate a professional guidance program under the perspective of the Behavior Analysis for non graduated professions. The program was composed by five meetings: the first and a part of the second were designated to the development of the contingencies concerning self knowledge and the knowledge of the other; the rest of the second and the third meetings boarded the contingencies referring the professional information and the professional world. Finally, the fourth and last meetings were about the contingencies of the decision taking. The specimen was composed careless of any education degree. The participants had, at minimum fourteen years old, and in the case of being under this age, they should at least have concluded junior high. The specimen were about to join the job market, they wouldn t go to a college (by their own choice); they belonged to the low socio-economic layer of the society and lived in a capital of one of the southern states of the country. Seventeen participants were selected and nine concluded the program. The study was done using two groups in separated ways. This was necessary because of the big quitclaim that happened in the first group right after the first meeting. The results obtained were analyzed separately for the two groups, for although they were exposed to the same methodology, the reduced number of participants in the first group couldn t allowed an statistic analysis that showed that the two specimen were of the same population. The statistic analysis was only made to the results obtained with Group 2 (G2). The statistic results showed that only in the discrimination feeling about the decision taking factor a difference with statistic matter happened. In qualitative terms, there was practically total satisfaction among the participants about the program methodology and structure. Besides that, functional analysis were made of some verbal episodes, in which some of the participants behavior trough the program and the reaching of the goals for each meeting could be evidenced. The program showed itself efficient in its goals, raised the participants variability to the professional information and made them more discriminative towards the decision taking process, upgrading of the verbal repertory. / A escolha profissional ? uma decis?o muito importante e normalmente est? vinculada ? quest?o da inser??o no ensino superior. Por?m a realidade atual seja em termos do acesso ao ensino, seja por escolha pr?pria, demonstra que n?o apenas as profiss?es universit?rias podem possibilitar estabilidade e realiza??o profissional. O mercado de trabalho necessita de profissionais com outros tipos de qualifica??es. O objetivo da pesquisa foi avaliar um programa de orienta??o profissional sob a perspectiva da An?lise do comportamento para profiss?es n?o universit?rias. Tal programa foi composto por 5 encontros: o primeiro e uma parte do segundo destinados as atividades de promo??o do autoconhecimento e conhecimento do outro; parte do segundo e o terceiro abordou a informa??o profissional e o mundo do trabalho. Por fim, o quarto e o ?ltimo fizeram refer?ncia ?s conting?ncias de tomada de decis?o. A amostra foi composta independente do n?vel de escolaridade. Os participantes tinham no m?nimo 14 anos ou, caso fossem menor do que essa faixa et?ria, deveriam ter conclu?do o Ensino Fundamental, estavam para ingressar no mercado de trabalho, n?o cursariam o ensino superior (por op??o pr?pria), pertenciam ? camada s?cio-econ?mica baixa e residiam em uma capital de estado do sul do pa?s. Foram selecionados 17 participantes e 9 conclu?ram o programa. O estudo foi realizado com 2 grupos, separadamente, devido a grande desist?ncia que ocorreu no primeiro grupo, logo ap?s o primeiro encontro. Os resultados obtidos foram analisados separadamente para os dois grupos, pois embora todos fossem expostos ? mesma metodologia, o n?mero reduzido de participantes no primeiro grupo n?o permitiu uma an?lise estat?stica que pudesse demonstrar se as duas amostras eram provenientes da mesma popula??o. Apenas para os resultados obtidos com o Grupo 2 (G2) foi realizada a an?lise estat?stica. Os resultados estat?sticos mostraram que apenas no fator referente ? discrimina??o dos sentimentos sobre a tomada de decis?o, houve diferen?a significante entre o teste pr? e o p?s-programa de Orienta??o Profissional. Em termos qualitativos, houve grande satisfa??o dos participantes em rela??o ? metodologia e a estrutura do programa. Al?m disso, foram feitas an?lises funcionais de alguns epis?dios verbais, as quais puderam evidenciar que os objetivos para cada encontro foram atingidos. O programa se mostrou eficaz nos seus objetivos, aumentou a variabilidade dos participantes em rela??o ? informa??o profissional e tornou-os mais discriminativos em rela??o ao processo de tomada de decis?o e aumentou os seus repert?rios verbais.

It has been analyzed how the business administrators - who live or work in the state of Rio de Janeiro, have been able to achieve satisfactory results in their meetings by using networks, especially e-mails and the internet as a tool of information technologies to decide processes, as well as have increased efficiency, which is a priority worldwide, and have, consequently, optimized the meetings. Although business meetings have a range of measurable parameters distinguishing them from one another, theoretically, some variables, such as communication, team work, decision making and information technologies may contribute to a better or worse performance of the professionals attending them. Based on the research which has been carried out with 68 business administrators who work in different areas, such as service industry, commerce and industry, it has been proved that 100% of these professionals consider it important to bring together people in order to work in teams, that normally vary from 4 to 8 people. According to what has been said by the professionals interviewed, those meetings should last, on average, one to three hours. A series of other characteristics of these meetings, as well as characteristics of the behavior of those attending the meetings has been unveiled throughout. Finally, the internet is a proven catalyst for saving time and money, which can be confirmed by the results: 93% of the people interviewed have answered that they do use electronic ways for internal communication; and 86% of the business administrators have reported that virtual interactions have been shown to be helpful and have shared the common objective of accelerating and enhancing human communications. By comparing the various tools available, we may conclude that e-mails, the intranet and video conferences are largely spread, what makes them a fundamental communication tool to accomplish a range of organizational goals. / O presente estudo foi realizado objetivando-se estudar o fen?meno organizacional das reuni?es de trabalho. Buscou-se analisar como os administradores domiciliados no Estado do Rio de Janeiro t?m conseguido obter resultados satisfat?rios em suas reuni?es, partindo-se da hip?tese de que quando esses profissionais se valem da internet, sobretudo dos correios eletr?nicos, como ferramenta de tecnologias de informa??o, em seus processos decis?rios, conseguem otimizar as reuni?es realizadas. A fundamenta??o te?rica isolou algumas vari?veis que atuam para um melhor ou pior desempenho dos profissionais presentes a essas reuni?es: comunica??o, trabalho em equipe, processo decis?rio e tecnologias da informa??o que auxiliem essas intera??es. Por meio da pesquisa cuja amostra foi de 68 administradores dos ramos de servi?o, ind?stria e com?rcio se p?de constatar que 100% desses profissionais consideram importante o ato de reunir suas equipes de trabalho, que normalmente variam de 4 a 8 pessoas reunidas e que duram em m?dia de 1 a 3 horas. Uma s?rie de outras caracter?sticas dessas reuni?es e do comportamento de seus participantes foi revelada ao longo da pesquisa apresentada, sendo que a hip?tese foi confirmada quando 93% os pesquisados responderam que usam meios eletr?nicos para suas comunica??es internas e que para 86% dos administradores as intera??es virtuais melhoraram os seus processos decis?rios e administra??o do tempo, destacando-se os correios eletr?nicos (emails) e a intranet entre as ferramentas mais difundidas no contexto organizacional, al?m da v?deo-confer?ncia no caso de contatos entre sede e filiais das empresas onde atuam os administradores.
