Para uma andragogia do esporte:discutindo as diretrizes e a formação profissional para a Educação Física de Jovens e Adultos

For the development of this research the following general objective has been formulated, indicator of the process of inquiry: To discuss the relation between the attitudinal and the sportive contents presented in the proposal of Curricular Lines for the Physical Education of Young and Adults in Brazil. According to the corporeity and the ludicity, questioning the formation of the professional of Physical Education and delineating the perspective for a sport andragogy that values the Being and the Life. From this general objective, the following objectives, which had given greater specificity to the investigative process, were defined: 1. To create the theoretical context from the corporeity/ludicity axis, articulating transversally sportive knowledge, aiming to contribute for a sport Andragogy; 2. To analyze the objectives proposed for the Physical Education of Young and Adults according to an elaborated theoretical reference and to the testimonies of the egresses of 2005 of the Physical Education course of the UFRN. 3. To interpret the relation between attitudinal and educative content from the academic reality lived by the egresses of the Physical Education course of the UFRN. 4. To understand the most urgent necessities of sustained formation of the egresses of 2005 for satisfactory performance with the Physical Education of Young and Adults. 5. To propose perspectives for the construction of a sport Andragogy from the corporeity/ludicity axis. In attendance to the nature of this research and as form of guiding ourselves in this epistemological adventure, the following ones had been basically and theoretically estimated. 1. Corporeity is a radiant focus, prime and main of educational criteria; 2. The task of the education must be carried through with men and not for men; 3. Man must only play with the beauty and with the beauty he only must play. ; 4. The sportive education must be based on esthetic and fair play. The adopted research approach is of a qualitative nature, using the interview procedure with a group consisting of twelve egresses of the Physical Education Course of the UFRN of the year of 2005.2 After the discussion of the results on the attitudinal objectives and content for the Physical Education for Adults and Young, the study shows nine themes presented by the investigated group as priorities for their sustained formation, aiming at the performance of the professional of Physical Education with the EJA: inclusive experiences; leisure and quality of life; relationships; body and personal care; social values; self esteem; sportive phenomenon; EJA training; attitudinal contents. As a contribution to the construction of knowledge for a Andragogy of Sports, the study presents a metaphorical structure called Galaxy of Knowledge righteous Glamor of integrating nine elements inspired by the Ode to the Sport of Pierre de Coubertin: life, beauty, justice, daring, honesty, joy; Fertility; progress; peace. At the heart of the structure of knowledge is righteous install a system that articulates five principles ludopoiético epistemological function of connecting with the righteous knowledge of the sport that must integrate the content attitudinal proposed for Fitness for Youth and Adults in order to facilitate the realization of their objectives proposed for this method of teaching

Representações sociais de professor partilhadas por licenciados a partir de imagens de professor

This investigation had the teacher as object of study, whose objective was to know and analyze the teacher‟s Social Representations (SR) shared by undergraduates, as from images of this professional (teachers´ photos of several levels and school systems). It was searched out the process of depreciation or estimation, in which the teaching profession has been passing, trying to catch, specifically, possible existing correlations among such SR and the reflections in the attitudes developed by these students about their own development and professional practice. The data collection was carried out at the Federal University of Piauí Teresina with 165 undergraduates (15 from each course). It was applied a semi-structured interview, mediated by iconographic grouping (SALES, 2000, 2007), outlining a methodological widening of the studies fulfilled by (ROAZZI, 1995). It was used the function Factor Analysis, available in the SPSS (Statistical Package for the Social Sciences) for the analysis of the quantitative data, and it was proceeded a content analysis through the categorical analysis technique (BARDIN, 1977) for the analytical procedures of the qualitative data. It was resorted to the SR theory (MOSCOVICI, 1978) for the data interpretation and the Theory of Signs (PEIRCE. 1995) in the understanding of the decodification processes of signs that were present in the photos worked. It became evident that the undergraduates perceived the teaching profession inserted in a hierarchical scale of values (positive/negative), directly related to the school system and the teaching level, in which the teacher works. Most undergraduates share teacher‟s SR of negative content, consolidating the hegemonic SR about the teacher‟s social depreciation, although some of them imagine themselves, in the future, inserted among the teachers more appraised, showing that the SR orientate the positive and negative attitudes about the teacher. The presence of SR that mobilize the interviewers‟ attitudes in opposite senses related to the teacher, offer evidence of the necessity of future studies that can use a methodology more focused to understand other motivation factors that the undergraduates give evidence of having to the course they have chosen, besides the ones inferred by the SR caught in this investigation, as well as to establish a correlation between the teacher‟s SR (positive and negative) and the social economic level of the interviewers that share them. Such data revealed itself necessary since the literature signalizes for a relation between the course chosen and the applicant‟s social-economic level, and that the applicants‟ objective conditions to the licenciature courses are related to the subjective hopes that their group supplies

Generalized linear mixed models for the genetic evaluation of binary reproductive traits: a simulation study

The objective of this study was to evaluate the use of probit and logit link functions for the genetic evaluation of early pregnancy using simulated data. The following simulation/analysis structures were constructed: logit/logit, logit/probit, probit/logit, and probit/probit. The percentages of precocious females were 5, 10, 15, 20, 25 and 30% and were adjusted based on a change in the mean of the latent variable. The parametric heritability (h²) was 0.40. Simulation and genetic evaluation were implemented in the R software. Heritability estimates (ĥ²) were compared with h² using the mean squared error. Pearson correlations between predicted and true breeding values and the percentage of coincidence between true and predicted ranking, considering the 10% of bulls with the highest breeding values (TOP10) were calculated. The mean ĥ² values were under- and overestimated for all percentages of precocious females when logit/probit and probit/logit models used. In addition, the mean squared errors of these models were high when compared with those obtained with the probit/probit and logit/logit models. Considering ĥ², probit/probit and logit/logit were also superior to logit/probit and probit/logit, providing values close to the parametric heritability. Logit/probit and probit/logit presented low Pearson correlations, whereas the correlations obtained with probit/probit and logit/logit ranged from moderate to high. With respect to the TOP10 bulls, logit/probit and probit/logit presented much lower percentages than probit/probit and logit/logit. The genetic parameter estimates and predictions of breeding values of the animals obtained with the logit/logit and probit/probit models were similar. In contrast, the results obtained with probit/logit and logit/probit were not satisfactory. There is need to compare the estimation and prediction ability of logit and probit link functions.

Arranjo de antenas de microfita com substrato anisotrópico com patch supercondutor e aplicações em nanotecnologia

The main objective in this work is the analysis of resonance frequency microstrip structures with glass fiber and electromagnetic band gap (EBG/PBG) substrate and analysis of microstrip antennas with rectangular patch of superconductor of high critical temperature (HTS). In this work was used the superconductors YBCO (critical temperature of 90K), SnBaCaCuOy (critical temperature of 160K), and Sn5InCa2Ba4Cu10Oy (critical temperature of 212K) with results in Gigahertz and Terahertz. Was used microstrip antennas arrays planar and linear phase and linear phase planar with patch with superconductor. It presents a study of the major theories that explain superconductivity. In phase arrays were obtained the factors arrays for such configurations, and the criteria of phase and spacing between the elements compound in the array, which were examined in order to get a main lobe with high directivity and high gain. In the analysis we used the method of Transverse Transmission Line (TTL) used in domain of the Fourier Transform (FTD). The LTT is a full wave method, which obtains the electromagnetic field in terms of the components transverse of the structure. The addition of superconductive patch is made using the boundary condition resistive complex. Results are obtained resonance frequency as a function of the parameters of the antenna, radiation patterns of the E and H Planes, for the phase antenna arrays in linear and planar configurations, for different values of the phase and the spacing between elements

Aplicações de arranjos de antenas de microfita com patch supercondutor

This work has as main objective the study of arrays of microstrip antennas with superconductor rectangular patch. The phases and the radiation patterns are analyzed. A study of the main theories is presented that explain the microscopic and macroscopic phenomena of superconductivity. The BCS, London equations and the Two Fluid Model, are theories used in the applications of superconductors, at the microstrip antennas and antennas arrays. Phase Arrangements will be analyzed in linear and planar configurations. The arrangement factors of these configurations are obtained, and the phase criteria and the spacing between the elements, are examined in order to minimize losses in the superconductor, compared with normal conductors. The new rectangular patch antenna, consist of a superconducting material, with the critical temperature of 233 K, whose formula is Tl5Ba4Ca2Cu9Oy, is analyzed by the method of the Transverse nTransmission Line (TTL), developed by H. C. C. Fernandes, applied in the Fourier Transform Domain (FTD). The TTL is a full-wave method, which has committed to obtaining the electromagnetic fields in terms of the transverse components of the structure. The inclusion of superconducting patch is made using the complex resistive boundary condition, using the impedance of the superconductor in the Dyadic Green function, in the structure. Results are obtained from the resonance frequency depending on the parameters of the antenna using superconducting material, radiation patterns in E-Plane and H -Plane, the phased antennas array in linear and planar configurations, for different values of phase angles and different spacing between the elements

Evolução da biodegradabilidade da matéria orgânica em um sistema de lagoas de estabilização

Waste stabilization ponds (WSP) have been widely used for sewage treatment in hot climate regions because they are economic and environmentally sustainable. In the present study a WSP complex comprising a primary facultative pond (PFP) followed by two maturation ponds (MP-1 and MP-2) was studied, in the city of Natal-RN. The main objective was to study the bio-degradability of organic matter through the determination of the kinetic constant k throughout the system. The work was carried out in two phases. In the first, the variability in BOD, COD and TOC concentrations and an analysis of the relations between these parameters, in the influent raw sewage, pond effluents and in specific areas inside the ponds was studied. In the second stage, the decay rate for organic matter (k) was determined throughout the system based on BOD tests on the influent sewage, pond effluents and water column samples taken from fixed locations within the ponds, using the mathematical methods of Least Squares and the Thomas equation. Subsequently k was estimated as a function of a hydrodynamic model determined from the dispersion number (d), using empirical methods and a Partial Hydrodynamic Evaluation (PHE), obtained from tracer studies in a section of the primary facultative pond corresponding to 10% of its total length. The concentrations of biodegradable organic matter, measured as BOD and COD, gradually reduced through the series of ponds, giving overall removal efficiencies of 71.95% for BOD and of 52.45% for COD. Determining the values for k, in the influent and effluent samples of the ponds using the mathematical method of Least Squares, gave the following values respectively: primary facultative pond (0,23 day-1 and 0,09 day-1), maturation 1 (0,04 day-1 and 0,03 day-1) and maturation 2 (0,03 day-1 and 0,08 day-1). When using the Thomas method, the values of k in the influents and effluents of the ponds were: primary facultative pond (0,17 day-1 and 0,07 day-1), maturation 1 (0,02 day-1 and 0,01 day-1) and maturation 2 (0,01 day-1 and 0,02 day-1). From the Partial Hydrodynamic Evaluation, in the first section of the facultative pond corresponding to 10% of its total length, it can be concluded from the dispersion number obtained of d = 0.04, that the hydraulic regime is one of dispersed flow with a kinetic constant value of 0.20 day-1

O leitor universitário e a construção das práticas de ler e escrever textos impressos e digitais

The construction of a mapping of the practices of reading and writing printed and digital texts, declared by graduating students from the Bachelor s degree in Science and Technology (BCT), has provided us the analysis of the course they are making in such a socio-historical moment characterized by the revolution of the post-paper. In this sense, the general objective of this research is to understand how that construction works under the point of view of those graduating students. For this, our reflection has been guided by the search of answers for some questions which have presented to us: what reading and writing conceptions BCT graduating students have; what reading and writing practices those collaborators develop; what collections they declare to have access to; what differences they declare to have between printed and digital reading and writing along the different social roles they develop; what the reader/writer identity relations of those collaborators are. To achieving the plausible answers, we have gathered a corpus composed by texts of three genres of the argument order: academic profiles (or self-portrait), opinion articles and argumentative letters. Besides, we have made semi-structured interviews and questionnaires in the online tool of the Google Docs. The methodology which supports this academic work is the qualitative research (SIGNORINI; CAVALCANTI, 1998)of ethnographic direction (THOMAS, 1993; ANDRÉ, 1995) in Applied Linguistics (CELANI, 2000; MOITA-LOPES, 2006) and the theoretical contribution comes from the bakhtinian perspective of language conception (BAKHTIN [1929] 1981); the socio-historical writing construction (LÉVY, 1996; CHARTIER, R., 1998, 2002, 2007; COSCARELLI, 2006; CHARTIER, A., 2007; ARAÚJO, 2007; COSCARELLI; RIBEIRO, 2007; XAVIER, 2009; MARCUSCHI; XAVIER, 2010); from the studies of the pedagogy of the writing (GIROUX, 1997); from the literacy studies understood as sociocultural practice, plural and situated (TFOUNI, 1988; KLEIMAN, 1995; TINOCO, 2003, 2008; OLIVEIRA; KLEIMAN, 2008), from the studies about identity in postmodernity (HALL, 2003; BAUMAN, 2005). The results of the analysis have pointed at a multiplicity of reading/writing practices of printed and digital texts developed by the BCT graduating students due to the coexistence of the modality printed and that one derived from the new mobile devices. In that multiplicity, the prevalent idea of the collaborators is that there is a continuum between printed texts and digital texts (not a dichotomy), since the option of reading/writing printed texts or digital ones is always linked to specific communication situations, which involve participants, objectives, strategies, values, (dis)advantages, besides (re)creation of discursive genres in function of the mobile devices to which those collaborators have access in the different spheres of activities that they participate. All of that has caused a deep intersection in the identity traces of college students readers/writers in the 21st century which cannot be ignored by academic formation
