Indicadores de desempenho e percepção subjetiva de esforço entre técnico e atletas de voleibol

The present study has for objective been to know the answers of performance indicators between different positions of volleyball and check for possible relationship between subjective perception referred by coach effort of volleyball athletes during training. Eleven athlete of the feminine sex, during eight weeks, 23 carried through sessions of training and eleven games, inferior members (Vertical Jump) and superiors had been evaluated by means of measures of explosive power in (Throw Medicine Ball), at the beginning and end of each week. For the verification of the subjective perceived of exertion it was used scales proposal for Foster (1998), to the end of each session of training. The collected data had been kept in computer file, producing information in the descriptive plan (measured central and dispersion) and the inferencial for the analysis of variance for the model with a factor complemented with the test of multiple comparisons of Tukey and linear correlation of Pearson. The results present as it has detached: i) the exercises specifics as content of bigger frequency in the training; ii) the test of vertical jump presented difference between the positions and, finally, iii) the subjective perceived of exertion between coach and athlete, he points that the trainer overestimates in 9,76% the perceived of the athletes. Such data are argued how much to the contents of the training as well as the load used in the interior of the process of preparation and monitoring of the training.

Possibilidades de enfoque CTS para o ensino superior de química: proposta de uma abordagem para ácidos e bases

Scientific education has been passing by redefinitions, contestations and new contributions from the research on science teaching. One contribution is the idea of science and technology literacy, allowing the citizens not only knowing science but also understand aspects on the construction and motivation of scientific and technological research. In accordance with this idea, there is the Science-Technology-Society (STS) studies which, since the 1970s, has been contributing for science teaching and learning according to the comprehension of the relationships with society in the Western countries of the North. In Brazil, this approach began to gain projection from the 1990s when the first essays on the theme were published. Currently, there is a clear influence of this approach on the national curriculum guidelines, especially for the area of Natural Sciences, and also on the textbooks chosen by the High School National Program (Programa Nacional do Ensino Médio). However, there seems to be a gap in relation to the discussion on the specific curricular component seen in college on this approach. Thus, this study aims at adopting the approach STS, face to the preparation of complimentary educational material on acid and bases concepts studied in the course of General Chemistry of the Natural Sciences graduation program. To this end, it was performed a bibliographical research aiming at making the state-of-the-art in in these concepts in specific literature to science teaching. It is divided in two stages: systematic study (with sixteen journals chosen according to Qualis-Capes and an unsystematic study with direct search in databases and references in the papers of the systematic study. The studies had their content analyzed and the categories chosen a priori were the level of education, the acid-base theory adopted, and the strategy/theoretical frame of reference adopted. A second stage aimed at identifying attitudes and beliefs on STS (Science-Technology-Society) and CSE (Chemistry-Society-Environment) of students in the teacher and technologist training course in three diferent institutions: UTFPR, UFRN and IFRN. In this study, it was used two questionnaires, composed of a Likert scale, semantic differential scale and open questions. The quantitative data reliability was estimated through Cronbach’s alpha method, and tha data were treated according to classic statistics, using the mean as the centrality measures, and the mean deviation as dispersion. The qualitative data were treated according to the content analysis with categories taken from the reading of answers. In the third stage, it was analyzed the presence of STS and CSE content in chapters on acid and bases concepts of nine General Chemistry textbooks, frequently used in graduation programs in public institutions of the state of Rio Grande do Norte. The results showed that there are few proposals of acid and bases teaching, and they are generally aimed at High School or at instrumentation for teaching courses, and no course for General Chemistry. The student’s attitudes and beliefs show the presence of a positivist point of view based on the concept of Science and Technology neutrality and the salvation of its mediation. The books analysis showed just a few content on STS and CSE are found in the studied chapters, and they are generally presented disjointedly in relation to the rest of the main text. In the end, as suggestion to solve the absence of proposals STS in General Chemistry books, as well as the student’s positivist attitudes, it was developed some educational material to be used in the course of General Chemistry at College. The material is structured to introduce a historical view of the concepts preparation, present the use of materials, the industrial and technological processes, and social and environmental consequences of this activities

Química em cena: uma proposta para formação inicial de professores de química

In educational observed difficulty in train teachers to meet the medium and higher education needs, and one reason for this is the different experiences in the training of educators in relation to those found in the classroom. So often arise criticisms related to relevance and efficiency of degree courses, as regards the performance of its natural mission, which weakens the teacher training. Thus, improving the quality of education is very dependent on the initiatives of teachers, creating teaching alternatives to strengthen their performance in school. From this reflection, it is concluded that teacher training needs new educational proposals that qualify, and so can promote the formation of his students more adequately. Among the educational proposals as alternatives to initial teacher training may use the scientific theater (TC). Considering this possibility, this work has been proposed as investigate and discuss the influence of TC combined with experimentation in the initial training of future teachers in Chemistry who participate in the Groups Fanatics chemistry Theatre (UERN) and Chemistry on Stage (UFRN). Therefore, there was, in a first stage, theatrical essays based on the theater of the oppressed, and written dramaturgical scripts, a collaborative proposal. To incorporate experimentation in chemistry to theater rehearsals, there was a systematic literature search and after content analysis, were selected categories, materials and reagents easily accessible, easy procedures and implementation with low risk of accidents and easy care chemical waste. In the second part we identified: a) the beliefs of student teachers in the use of TC ally trial for initial training of chemistry teachers; b) the influence of TC ally to trial on learning of chemical concepts of high school students who attended the shows; c) the reasons for using or not TC ally to trial by chemistry teachers who participated in the TC group and currently work in the classroom. In this study, questionnaires and interviews were used, compounds, respectively, by a Likert scale and open questions. Quantitative data were analyzed by classical statistics the media, using as centrality measures the average, the concordance argument and the average deviation. Qualitative data were discussed according to content analysis, with categories that emerged from reading the answers. These analyzes concluded that the licensees have a positive view on the use of scientific theater for disclosure of the chemical for use in the learning of chemical concepts, pedagogical and disciplinary knowledge, and to form promotion strategy for research and extension at the University. They credit improvements in their initial training on the use of scientific theater combined with experimentation. The TC provides motivation for the construction of conceptual thinking in an informal way of chemical communication, allowing the student to expand their knowledge, not only favoring the phenomenological approach, but also the construction of chemical knowledge and the internalization of scientific concepts.

Caracterización de la curva de lactancia y el comportamiento reproductivo de vaquillas Holstein bajo implementación de medidas de manejo en el período pre-parto

Con el objetivo de caracterizar la curva de lactancia y evaluar el comportamiento reproductivo se analizaron los registros mensuales (N=10) de vaquillas Holstein bajo la implementación y falta de implementación de medidas de manejo pre-parto en la Empresa Agropecuaria “San Ignacio” Mateare, Nicaragua. Para caracterizar la curva de lactancia, se utilizó el modelo de Wood (1967) de forma linealizada Ln Yx = Lna + b Lnx - ex , donde Yx es la producción diaria en el período x, a representa la producción inicial, b el ascenso al pico, c el descenso de producción, a partir del mismo se generaron la Persistencia (S), Rendimiento al pico (RP), Tiempo al pico (TP), también se evaluó el Intervalo parto - concepción (IPC) y el Número de servicios por concepción (NSPC) . Al presentar problemas reproductivos la proporción de curvas atípicas encontradas en este Trabajo fue de 40%. Al analizar la curva de lactancia del grupo experimental se observa un a= 11.00212 kg, b = 0.083528 kg, e = 0.00407148 kg, RP = 12.790 kg, TP = 29.54 días, S = 6.126. El grupo testigo presenta un a = 6.4384 kg, b = 0.193048 kg, e = 0.00466974 kg, RP = 9.49 kg, TP = 34.32 días, S = 6.421. En el análisis de varianza se encontró que el RP tiene diferencia significativa entre los tratamientos a un nivel de significancia (P<0.05). Los parámetros reproductivos IPC y NSPC para el grupo experimental fueron de 243.6 días y 3 servicios respectivamente, el grupo testigo presentó un IPC = 221.8 días y NSPC = 3.6 servicios .

Evaluación perceptivo auditiva de voces degradas y su correlación con medidas acústicas

Resumen: El objetivo es determinar utilizando las mediciones acústicas, qué información es más relevante para el oyente al momento de categorizar el grado general de disfonía. Se eligieron 8 (4 voces femeninas y 4 voces masculinas. Cada emisión fue evaluada auditivo perceptualmente a través del item G de la escala GRBAS por 10 oyentes experimentados y acústicamente mediante medidas de aperiodicidad, ruido y caos. El estudio estadístico de análisis discriminante señala la importancia de GNE, Jit y Jitter_cc y Lyapunov como parámetros predictores del grado general de disfonía. La aplicación del método k-means evidencia que existen rasgos en los parámetros acústicos empleados que permiten agrupar objetivamente las voces estudiadas con 100% de precisión para la clase 0, 96% a la clase 2 y 79% a la clase 3. Un mayor número y variabilidad de casos se necesita a fin de verificar los resultados preliminares.

Medidas alternativas de la pobreza en el Gran Buenos Aires, 1995-2006

Resumen: En este trabajo, calculamos y analizamos el Índice de Severidad de la pobreza o squared poverty gap para el Gran Buenos Aires, en el período 1995-2006. Este índice es una de las tres medidas más conocidas correspondientes a la clase FGT (Foster, Greer and Thorbecke 1984), aunque menos utilizada que la incidencia o head count ratio (calculado por el INDEC), y la brecha de pobreza o poverty gap. El Índice de Severidad de la pobreza tiene en cuenta no sólo la distancia que separa a los pobres de la línea de pobreza (como en el caso de la brecha de pobreza) sino también la desigualdad entre los pobres. Es decir, le da un mayor peso a los hogares que están más alejados de la línea de pobreza. Por lo tanto, este índice cumple con el axioma de transferencia, a diferencia de los otros dos. Calculamos el Índice de Severidad tanto a nivel hogares como individuos. Además, realizamos una descomposición del índice por grupos – según la situación laboral, el nivel de educación, el tamaño del hogar, la edad y el sexo del jefe de hogar; y calculamos el riesgo relativo de cada grupo. Realizamos también una comparación entre los índices de incidencia (INDEC) y severidad. Concluimos presentando los índices de incidencia y severidad para todo el país, y su descomposición por regiones, para el año 2006.

Una aplicación de las medidas de Alkire-Foster al estudio de la pobreza y desigualdad multidimensional de los hogares urbanos argentinos entre 2004 y 2008

Resumen: Si bien el período de recuperación posterior a la crisis del fin de la convertibilidad mostró mejoras en las mediciones de pobreza y desigualdad monetarias, el análisis de medidas multidimensionales permite detectar un estancamiento en estas mejoras ya a partir del año 2007. Este documento intenta indagar en los componentes de este cambio, mediante un ejercicio de descomposición temporal y por grupos de la medida Alkire-Foster (2007) aplicada a los datos de la Encuesta de la Deuda Social Argentina.
