A estrutura subcognitiva da visão estratégica : um experimento psicológico sobre a natureza dos Chunks

How strategical decisions are taken? The present work consists of a psychological experiment that it aims to search the knowledge about the subcognitive structure of strategical vision of deeper form, investigating its interaction with the cognitives processes of human beings ¿ perception, memory, and learning. We also argue the nature of chunks (pieces or units), that, in opposition to the current theories, we consider to be provided with essence or meanings in detriment of the appearance or superficial features. In this way, we choose as domain for our experiment the chess game, because its dealing with lesser complexity of the one that decisions in the politics or industry. Thus, we shows the importance that the perception of the abstract roles playing in specific chess position, leading to a strategical vision of this. Moreover, after the experiment, was verified that the expert chess players are capable to perceive distinct positions in the appearance as being similar strategically", while that the beginners had gotten greater difficulty. Finally, we present part of an emergent theory that claims that the human being cognition is nothing more than the abstract perception, as well as the replication of this theory in other domains, for example in the management and the real world."

Dança Folclórica: um estudo das qualidades físicas básicas em universitários de diferentes níveis técnicos

Health and life quality can be preserved and improved by the regular practice of physical activity. Sedentarism is an undesirable condition and represents risk for the health. This study has as objective to analyze the caloric cost and the basic physical qualities in college students of different technical levels. The research was descriptive and applied to 35 students, volunteers, from 19 to 34 years old, from both sexes, participants of the Dance Body of State University of Piauí, in the city of Teresina, in the activities of folkloric dance and walking. The caloric cost was evaluated with the accelerometer Caltrac 100/100 Plan, the basic physical qualities through the sitting and reaching test (flexibility); the vertical impulsion test, crouch (inferior members strength); the abdominal test (located muscular resistance); and the Burpee test (motor coordination). The participants were separated in two groups according to their time of practice: group 1 (beginners), group 2 (advanced). The parametric tests t by Student and correlation by Pearson were used, observing a significance p<0,05 in the sense of comparing the observed results, which showed that there are no significant differences between the two groups of students, according to the time of practice, in which concerns the caloric cost. The results of Strength, Resistance and Co-ordination test did not differ so much between the two groups. On the other hand, in the variable flexibility significant differences were observed (sig.p = 0,0022 << 0,05) between the observed groups, being Group 1 (31,5 ± 6,3) meaningfully less than Group 2 (38,1 ± 4,9), which constitutes a difference of about 21%. Such results present relations of caloric cost compensation between the studied groups, the motivation to the beginners group and flexibility to tne advanced group, justifying the lack of significant distinctions. In this sense the folkloric dance, as a physical activity, appears to be efficient, for significant co-relations are still noticed between the caloric cost levels of the dance with the walking, besides not presenting expressive differences between them.

Um estudo sobre o estágio supervisionado na formação inicial de professores de matemática na Bahia

This work arose from our concerns with the issues of teacher training for early childhood education. From the difficulties encountered as a novice teacher in elementary, we deem important to research training needs of these professionals. Thus, we define the objective of this research to investigate the training needs of novice teachers teaching Early Childhood Education/Elementary school. Our work fits in Educational Research Qualitative Approach, and its construction procedures of the semistructured interview data and document analysis. Our empirical field was made up of schools in the metropolitan region of Natal / RN, offering kindergarten / elementary school. The subjects are five teachers who act as holder of the elementary school class and have 0-3 years of teaching practice, characterizing the second Huberman (2007) as novice teachers. Data analysis, based on principles of content analysis, three themes emerged: Beginner Teaching Professor in Early Childhood Education / Preschool; Reasons explaining the difficulties Faculty / Formative Needs Teaching and Training in Early Childhood Education / Elementary school, from the Training Needs Analysis, with their respective categories, subcategories, contributing to our understanding of the subject matter. The entry into the profession is marked by mixed feelings of euphoria and fear, where there seems to be a "clash" with reality. The difficulties are related to the planning / execution of activities, meet the individual needs of learning and assessment of children. As a strategy to overcome the difficulties the teachers exercise the action-reflection-action in their practices and seek continuous updates in the theoretical and methodological framework of early childhood education. The reasons that define these difficulties may be related to the teacher, school, family, and students of these institutions. In experiencing these difficulties has outlined the need for teacher training, among which stand out studies on ethics in teaching with children, the concept of children and their childhoods, peculiarities of teaching / learning in preschool, toys and legal determinations on early childhood education, multi-language and expressions in early childhood education, specific content areas of knowledge, among others. Furthermore, studies on the theoretical as Piaget, Vigotsky, Maria Carmen Barbosa and Emily Smith. For these professionals to be a professional early childhood education is: like children, be patient and careful, have specific theoretical and practical training for teachers in kindergarten, being able to improvise with seriousness and competence and get updates on continuing education. The surveys, together with the authors and teachers, to confirm our understanding that the training needs of beginners may be related to shortcomings in the initial and continuing education

Trajetória de carreira do profissional de recursos humanos

The idea that the career consists in a linear path throughout the individual s professional life structured by the company where he or she works has been changing to a new reality in which the career is seen as a journey, open to possibilities and uncertainties. Several models have come up as an attempt to comprehend and analyze this journey. Among them, there is the model of career narrative, which assumes that, while narrating, individuals give meaning to their own path, and at the same time they consider personal factors and the environment that act on their professional biography. This paper aimed to explore and articulate issues related to the environment and career paths of the human resource professionals working in the Greater Natal. For this purpose, the model of career narrative was used. From the methodological viewpoint, the project was divided in two stages. The first was characterized by conducting a survey with the intention of mapping professionals socio-occupational characteristics, through the application of a semi-structured questionnaire. The data was analyzed by descriptive statistical techniques and cluster analysis. The descriptive statistical analyses included 117 participants. The results indicated that HR professionals of Greater Natal have different functions, develop activities focused on different subsystems, have an increasing career path, and focus their professional formation in Business Administration and Psychology. The second stage of the study was characterized by the use of 17 narrative interviews, whose participants, in the process of nonprobabilistic sampling, were identified based on their belonging to the three clusters: Group 1, HR and public administration; Group 2, HR experts; and Group 3, HR beginners. Analyzing the results of the qualitative phase, it was found that the identification with the activity practiced is a deciding factor for choosing and remaining in the HR field. The lack of professional recognition appears as the main difficulty faced by professionals, as well as the lack of employment opportunity in the Greater Natal. The results analysis leads to a series of discussions on the career path in HR and reflections for this professional category, its representative bodies and educational institutions

Blood lactate response and critical speed in swimmers aged 10-12 years of different standards

It has previously been shown that measurement of the critical speed is a non-invasive method of estimating the blood lactate response during exercise. However, its validity in children has yet to be demonstrated. The aims of this study were: (1) to verify if the critical speed determined in accordance with the protocol of Wakayoshi et al. is a non-invasive means of estimating the swimming speed equivalent to a blood lactate concentration of 4 mmol . l(-1) in children aged 10-12 years; and (2) to establish whether standard of performance has an effect on its determination. Sixteen swimmers were divided into two groups: beginners and trained. They initially completed a protocol for determination of speed equivalent to a blood lactate concentration of 4 mmol . l(-1). Later, during training sessions, maximum efforts were swum over distances of 50, 100 and 200 m for the calculation of the critical speed. The speeds equivalent to a blood lactate concentration of 4 mmol . l(-1) (beginners = 0.82 +/- 0.09 m . s(-1), trained = 1.19 +/- 0.11 m . s(-1); mean +/- s) were significantly faster than the critical speeds (beginners = 0.78 +/- 0.25 m . s(-1), trained = 1.08 +/- 0.04 m . s(-1)) in both groups. There was a high correlation between speed at a blood lactate concentration of 4 mmol . l(-1) and the critical speed for the beginners (r = 0.96, P < 0.001), but not for the trained group (r = 0.60, P > 0.05). The blood lactate concentration corresponding to the critical speed was 2.7 +/- 1.1 and 3.1 +/- 0.4 mmol . l(-1) for the beginners and trained group respectively. The percent difference between speed at a blood lactate concentration of 4 mmol . l(-1) and the critical speed was not significantly different between the two groups. At all distances studied, swimming performance was significantly faster in the trained group. Our results suggest that the critical speed underestimates swimming intensity corresponding to a blood lactate concentration of 4 mmol . l(-1) in children aged 10-12 years and that standard of performance does not affect the determination of the critical speed.

Desempenho motor no esporte: das restrições do iniciante ao experiente

A set of constraints on the performance of motor skills is a determinant factor of success in many sport modalities that require from the athlete continuous adaptation to changes in the game context. Taking into account Newell's model of organism (or performer), task and environmental constraints in the acquisition of motor skills (NEWELL, 1986), the focus of this study is the set of changes that take place in motor behavior from the beginner to the high level athlete. In specific, the focus is toward changes in sports settings in which the ball is the center of the game, responsible for the relationship among athletes of the same team as well as between opponents, as in volleyball. The ball, in its trajectory, carries on a set of constraints to the player's behavior. To be able of imposing constraints on the opponent's behavior is so important as to know how to deal with a ball sent to you by the opponent in an unpredictable trajectory.

Treino musical e capacidade da memória operacional em crianças iniciantes, veteranas e sem conhecimentos musicais

A memória operacional e a atividade musical ativam áreas encefálicas recíprocas e homólogas, contudo não há evidências se o treino musical pode ampliar a capacidade da memória operacional. Objetivo: Avaliar o desempenho do treino musical sob a memória operacional em crianças de 9 e 10 anos de idade, praticantes de treino musical e sem experiência musical. PARTICIPANTES: Crianças Iniciantes (n=20), Veteranas (n=20) e Grupo Controle (n=20). MATERIAIS: Instrumentos computadorizados para avaliação da memória operacional. RESULTADOS: Crianças veteranas apresentaram melhores pontuações no BCPR (Teste de Repetição de Pseudopalavras para crianças brasileiras) e em subtestes da AWMA (Avaliação Automatizada da Memória Operacional). CONCLUSÃO: O treino musical parece ter contribuído para o desenvolvimento da memória operacional em crianças veteranas no programa de treino musical.
