La coeducaci??n en los recreos : propuesta de intervenci??n did??ctica en Educaci??n F??sica atendiendo a las relaciones de g??nero entre los estudiantes, mediante el uso del material autoconstruido

Analizar el comportamiento del alumnado de Educaci??n Primaria de un colegio durante los periodos de recreo escolar y contrastar si el g??nero es una variable diferencial en cuanto a sus relaciones interpersonales cuando se les involucra en el uso de materiales autoconstruidos y estudiar las percepciones de los estudiantes de Educaci??n Primaria en cuanto a sus propias relaciones de g??nero cuando disponen libremente y no disponen del material autoconstruido durante los periodos de recreo son los objetivos de esta investigaci??n. Estructurada en tres partes: a) revisi??n te??rica del objeto de estudio, la coeducaci??n en el centro escolar y, m??s concretamente, durante los recreos: b) observaci??n durante los recreos de las relaciones que se producen entre los estudiantes, atendiendo especialmente a las relaciones con el otro g??nero, con o sin material autoconstruido; y c) desarrollo y aplicaci??n de una Unidad did??ctica durante las clases de Educaci??n F??sica y estudio de c??mo afecta ??sta en las relaciones de g??nero en las diferentes agrupaciones propuestas cuando se usa el material autoconstruido. Del an??lisis de los datos obtenidos, mediante la observaci??n directa no participante y de los cuestionarios pretest y postest, se concluye que el uso del material autoconstruido promueve que el reparto de la zona de juegos sea m??s equitativo por parte de ambos sexos. Igualmente limita las exclusiones y conflictos que se producen en los diferentes juegos o deportes convencionales en relaci??n al g??nero, favoreciendo la coeducaci??n, concretamente, en los periodos de recreo escolar. Finalmente, se propone un ejemplo de intervenci??n con materiales autoconstruidos en la clase de Educaci??n F??sica encaminada a favorecer la coeducaci??n. Para ello, se elabor?? una serie de sesiones con diferentes actividades encaminadas a favorecer la igualdad entre chicos y chicas. Se comprob?? que en la clase de Educaci??n F??sica, los juegos cooperativos unidos al material autoconstruido provocan una serie de actitudes positivas en las interacciones entre los estudiantes, promoviendo entre ellos, al igual que en los recreos, un uso m??s igualitario del espacio, la reducci??n de los conflictos y un aumento de las relaciones entre g??nero que repercute directamente en la cantidad y calidad de Educaci??n F??sica que realizan las chicas. Por ello, se concluye que el material no convencional desde el punto de vista actitudinal, puede favorecer la coeducaci??n, mejorar las interacciones interpersonales, la comunicaci??n, el trabajo en grupo y propiciar el disfrute y la diversi??n de todos los estudiantes.

La incontinencia urinaria en el cáncer de próstata: diseño de un programa de rehabilitación

Este trabajo presenta el diseño e implementación de un programa progresivo de rehabilitación basado en los ejercicios musculares del suelo pélvico, incorporando el trabajo muscular de fuerza contrarresistencia. El disenño del estudio es casi experimental.La muestra es de 33 participantes en fase de tratamiento. Las variables de estudio son las antropométricas, las relacionadas con la evolución de la incontinencia urinaria(IU (intensidad, dificultad, frecuencia y limitación de las actividades),la obesidad, fatiga y dolor,la fuerza muscular y la calidad de vida(CdV). Para evaluar el cambio intrasujeto se tomaron medidas pretest(semana 0)y postest(semana24. En el análisis estadístico se utilizan las pruebas t Student-Fisher, Wilcoxon oU de Mann Whitney y el test del w2. El análisis se realiza con el programa SPSS versión 15. El nivel de significación escogido es del 5%. Al finalizar las 24 semanas del programa se identifica una disminución significativa de las variables antropométricas índice de cintura cadera (p¼0,003), perímetro de cintura(pr0,001) y porcentaje de masa de grasa(pr0,001); de las variables de IU: intensidad(pr0,0001), frecuencia y dificultad y su relación con la limitación de las actividades (pr0,0001), así como la relación existente entre la mejora de IU y la mejora de la CdV(p¼0,039). Queda científicamente demostrada la eficacia del programa progresivo de fuerza para disminuir la IU. La mejora de la CdV del hombre mayor con cáncer de prósstata viene mediada por la mejora de la continencia urinaria

Effect of priming cooperation or individualism on a collective and interdependent task: changeover speed in the 4 x 100-meter relay race

Priming effects of cooperation vs. individualism were investigated on changeover speed within a 4 x 100-m relay race. Ten teams of four adult beginner athletes ran two relays, a pretest race and an experimental race 3 weeks later. Just before the experimental race, athletes were primed with either cooperation or individualism through a scrambled-sentence task. Comparing to the pretest performance, cooperation priming improved baton speed in the exchange zone (+30 cm/s). Individualism priming did not impair changeover performance. The boundary conditions of priming effects applied to collective and interdependent tasks are discussed within the implicit coordination framework.

The indirect amygdala-dorsal striatum pathway mediates conditioned freezing: Insights on emotional memory networks

The dorsal striatum (DS) is involved in various forms of learning and memory such as procedural learning, habit learning, reward-association and emotional learning. We have previously reported that bilateral DS lesions disrupt tone fear conditioning (TFC), but not contextual fear conditioning (CFC) [Ferreira TL, Moreira KM, Ikeda DC, Bueno OFA, Oliveira MGM (2003) Effects of dorsal striatum lesions in tone fear conditioning and contextual fear conditioning. Brain Res 987:17-24]. To further elucidate the participation of DS in emotional learning, in the present study, we investigated the effects of bilateral pretest (postraining) electrolytic DS lesions on TFC. Given the well-acknowledged role of the amygdala in emotional learning, we also examined a possible cooperation between DS and the amygdala in TFC, by using asymmetrical electrolytic lesions, consisting of a unilateral lesion of the central amygdaloid nucleus (CeA) combined to a contralateral DS lesion. The results show that pre-test bilateral DS lesions disrupt TFC responses, suggesting that DS plays a role in the expression of TFC. More importantly, rats with asymmetrical pre-training lesions were impaired in TFC, but not in CFC tasks. This result was confirmed with muscimol asymmetrical microinjections in DS and CeA, which reversibly inactivate these structures. On the other hand, similar pretest lesions as well as unilateral electrolytic lesions of CeA and DS in the same hemisphere did not affect TFC. Possible anatomical substrates underlying the observed effects are proposed. Overall, the present results underscore that other routes, aside from the well-established CeA projections to the periaqueductal gray, may contribute to the acquisition/consolidation of the freezing response associated to a TFC task. It is suggested that CeA may presumably influence DS processing via a synaptic relay on dopaminergic neurons of the substantia nigra compacta and retrorubral nucleus. The present observations are also in line with other studies showing that TFC and CFC responses are mediated by different anatomical networks. (C) 2008 IBRO. Published by Elsevier Ltd.

Bayesian analysis of skew-t multivariate null intercept measurement error model

The multivariate skew-t distribution (J Multivar Anal 79:93-113, 2001; J R Stat Soc, Ser B 65:367-389, 2003; Statistics 37:359-363, 2003) includes the Student t, skew-Cauchy and Cauchy distributions as special cases and the normal and skew-normal ones as limiting cases. In this paper, we explore the use of Markov Chain Monte Carlo (MCMC) methods to develop a Bayesian analysis of repeated measures, pretest/post-test data, under multivariate null intercept measurement error model (J Biopharm Stat 13(4):763-771, 2003) where the random errors and the unobserved value of the covariate (latent variable) follows a Student t and skew-t distribution, respectively. The results and methods are numerically illustrated with an example in the field of dentistry.

Using Clickers to Teach Biology-Based Material in a Developmental Psychology Class

This talk will describe a study designed to assess if clicker technology during a lesson can improve learning relative to traditional lecture alone. A control group was exposed to the stages of prenatal development via traditional lecture, and an experimental group was exposed to the material via an exercise that used clickers. A pretest showed no difference before the intervention. A posttest showed that the clicker group had significant gains indicating clickers may facilitate learning of science-based material.

A teoria de Dienes no ensino de transformação de medidas de comprimento, área e volume no curso de pedagogia

The study was aimed to test a teaching module on the Zoltan Paul Dienes theory, focusing on the content: The transformation of measurements: length, areas and volumes. The study based on constructivist theory consisted in a methodological intervention with students of the 7th period of the Course of Pedagogy, in Central Campus, Federal University of Rio Grande do Norte (UFRN). A preliminary study with 40 students called diagnostic evaluation found that students did not understand the concept of measurements transformation and its processing steps. The latter was performed only with the help of the table of measurements transformation with no understanding of the content. He applied a pretest, a set of activities and a post-test. The latter was used as a tool for evaluation of the student learning process. The answers of these ones were evaluated according to the concept of reflective abstraction of Jean Piaget, one of the authors who influenced the Dienes theory

Tradução e adaptação transcultural do instrumento de avaliação prenatal selfevaluation questionnaire

Introduction: The human gestation period is 40 weeks. This is the essential time for maternal psychosocial adaptation, in which there is the intense transformation of a life without offspring into a life with one or more children. The Pregnancy Self-Evaluation Questionnaire (PSEQ) has 79 items, subdivided into seven subcategories: acceptance of pregnancy, identification with the maternal role, well-being of mother and baby, preparing for labor, control in labor, relationship with the mother and the relationship with the partner. Objective: To translate and cross-culturally adapt the instrument PSEQ to be used with Brazilian women. Methods: It is a cross-sectional observational study. We followed some methodological steps to achieve the cross-cultural adaptation of this measuring instrument. They are: translation, synthesis, back translation, analysis of the committee of specialists and pre-test. Another questionnaire was applied to characterize the socio-demographic and clinical status of the pregnant women (n = 36). The descriptive statistics was gotten through the average, standard deviation (SD), absolute and relative frequency. The statistical test used for the analysis of the internal consistency was Cronbach's alpha coefficient, using SPSS version 17.0. Results: The volunteers had low socioeconomic status, average age of 25.1 years (± 5.52), and average gestational age of 25.9 weeks (± 8.11). 58.3% of these volunteers had not planned their current pregnancy. The pretest showed that 75% of pregnant women found the questionnaire easy to understand. There was an average of 76.9 (± 3.23) answered items among the participants. Regarding the instrument PSEQ, the identification with the maternal role was the subcategory which showed the highest average 24.8 (± 5.6), while the relationship with the mother had the lowest average 15.4 (± 7.7). The internal consistency ranged from 0.52-0.89. Conclusion: The translation and cross-cultural adaptation of the PSEQ to Portuguese language were carried out with methodological rigor and can be considered an instrument with good internal consistency
