A perceção dos alunos do 3º ciclo sobre a aprendizagem da Língua Portuguesa, da Matemática e da Educação Física

Para garantir a melhor aprendizagem para os alunos nas escolas, de forma a assegurar uma educação de qualidade e assim uma consequente preparação para o futuro dos mesmos na sociedade, é crucial que as escolas adotem estratégias de inclusão, de maneira a adaptar o ensino e a aprendizagem às diferentes características e necessidades dos alunos, e à diversidade que hoje em dia está patente no sistema de ensino. De forma a fomentar a educação inclusiva, é importante que as escolas e os professores organizem o processo ensino-aprendizagem com base na aprendizagem cooperativa, realizada em grupos heterogéneos, onde o sucesso do grupo depende de todos os alunos que o constituem. As interações estabelecidas tanto no seio do grupo como também entre o professor e o grupo de alunos, são fundamentais, pois são consideradas um fator positivo que assegura uma aprendizagem de qualidade sustentada nas relações de interdependência existentes entre alunos e professores. O objetivo deste estudo é perceber qual a perceção dos alunos do 3º ciclo relativamente à aprendizagem na sala de aula nas disciplinas de Língua Portuguesa, Matemática e Educação Física e se essas perceções variam de forma positiva ou negativa em função da disciplina em causa. A amostra foi constituída por 1159 alunos do 3º ciclo, à qual foi aplicado o questionário “A perceção dos alunos sobre a aprendizagem na sala de aula” (A.S.A - P.A., Leitão, 2012). Concluiu-se que os alunos têm uma perceção mais positiva sobre as aprendizagens na disciplina de Educação Física quando comparada com as demais. A perceção dos alunos do 3º ciclo relativamente à interdependência aluno/aluno varia em função da disciplina. Relativamente à interdependência professor/aluno, a perceção dos alunos só não varia entre as disciplinas de Língua Portuguesa e Educação Física quando comparadas. Já em relação à negociação, a perceção dos alunos apenas varia entre as disciplinas de Língua Portuguesa e Matemática quando comparadas. Por fim, referente à meta-aprendizagem concluímos que a perceção dos alunos do 3º ciclo não varia em função da disciplina.

A study of threshold and loudness summation in listeners with sensorineural hearing impairments

This paper investigates loudness summation in a group of listeners with moderate to severe hearing losses and the applicability of this information to hearing aid fittings.

Evaluating social skills in long term cochlear implant recipients

A longitudinal study observing cochlear implant recipients' social skills using ratings from their parents and the students themselves over time. The study looked at how adolescents using cochlear implants rate their own social skills compared to an age matched normative group of hearing students, and compared these ratings with social skills ratings obtained from their parents. The study also compared social ratings in adolescence to previous ratings of the same children obtained in elementary school.

Las claves semióticas de la televisión

La presente investigación aborda dos aspectos sobresalientes de la realidad mediática de nuestro tiempo: el discurso televisivo y la narrativa audiovisual; omnipresencia que amerita desplegar esfuerzos académicos que den cuenta de su estructura y funcionamiento, pues su incidencia sigue creciendo y proyectándose en medios tan portentosos como la internet, y en otras manifestaciones cotidianas como el videoclip, la publicidad o la misma grabación casera. El libro se adentra en el discurso televisivo para definir, explicar y esquematizar aspectos como el texto, el género, el programa, el formato y la programación, a la luz de los aportes de autores clásicos y contemporáneos. El estudio de la narrativa audiovisual, con base en los principios de la narratología y del cine, también es objeto de análisis, e involucra lo más trascendente de esta dimensión enunciativa: el relato, la historia narrativa y la narración, y sus fascinantes implicaciones. En virtud de su carácter teórico-metodológico, la obra incluye una síntesis conceptual de los temas fundamentales, con acotaciones y claves metalingüísticas, sin olvidar las fuentes y los autores más representativos, lo que allanará el recorrido científico y los afanes hermenéuticos de los lectores y lectoras.

Repensando la tradición y la diferencia (Debates)

La lectura y discusión de este texto de Herán lbarra es recomendable, por un lado porque constituye un aporte ecuatoriano al debate especializado acerca del significado de las rebeliones indigenas, tema que ha ocupado un espacio importante en la historiografta andina, por otro lado porque es un texto significativo en la discusión acerca del proceso de definición de identidades politicas actuales en nuestro país. El estudio de Ibarra plantea tres entradas al tema de la rebelión indígena, especificamente la de Yaruquíes, ocurrida en 1871, cuyo protagonista más conocido es Fernando Daquilema. La primera entrada es un acercamiento a las interpretaciones y apropiaciones que se han generado alrededor de este hecho histórico y este personaje. La segunda, es un estudio del contexto de los cambios sociales que afectaron a los indígenas en general \ durante el siglo XIX y en especifico a la zona lévantisca ubicada en la sierra central. Un tercer tema es la interpretación del sentido politico de este levantamiento y sus reivindicaciones. Por último Ibarra incluye tres anexos, el primero es un Cuadro que muestra el número de indígenas contribuyentes del trabajo subsidiario en Riobamba entre 1856-1871, diferenciando haciendas de comunidades. El segundo es el juicio criminal seguido a Serafín Ipo, por el tumulto en Yaruquíes y por último una exposición del Ministro del Interior y Relaciones Exteriores, en 1873, relativo al estado de sitio declarado en Chimborazo.

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. II: Changing ENSO regimes

Integrations of a fully-coupled climate model with and without flux adjustments in the equatorial oceans are performed under 2×CO2 conditions to explore in more detail the impact of increased greenhouse gas forcing on the monsoon-ENSO system. When flux adjustments are used to correct some systematic model biases, ENSO behaviour in the modelled future climate features distinct irregular and periodic (biennial) regimes. Comparison with the observed record yields some consistency with ENSO modes primarily based on air-sea interaction and those dependent on basinwide ocean wave dynamics. Simple theory is also used to draw analogies between the regimes and irregular (stochastically forced) and self-excited oscillations respectively. Periodic behaviour is also found in the Asian-Australian monsoon system, part of an overall biennial tendency of the model under these conditions related to strong monsoon forcing and increased coupling between the Indian and Pacific Oceans. The tropospheric biennial oscillation (TBO) thus serves as a useful descriptor for the coupled monsoon-ENSO system in this case. The presence of obvious regime changes in the monsoon-ENSO system on interdecadal timescales, when using flux adjustments, suggests there may be greater uncertainty in projections of future climate, although further modelling studies are required to confirm the realism and cause of such changes.

Sufficiency of Favard's condition for a class of band-dominated operators on the axis

The purpose of this paper is to show that, for a large class of band-dominated operators on $\ell^\infty(Z,U)$, with $U$ being a complex Banach space, the injectivity of all limit operators of $A$ already implies their invertibility and the uniform boundedness of their inverses. The latter property is known to be equivalent to the invertibility at infinity of $A$, which, on the other hand, is often equivalent to the Fredholmness of $A$. As a consequence, for operators $A$ in the Wiener algebra, we can characterize the essential spectrum of $A$ on $\ell^p(Z,U)$, regardless of $p\in[1,\infty]$, as the union of point spectra of its limit operators considered as acting on $\ell^p(Z,U)$.

Climate entropy budget of the HadCM3 atmosphere-ocean general circulation model and of FAMOUS, its low resolution version

The entropy budget is calculated of the coupled atmosphere–ocean general circulation model HadCM3. Estimates of the different entropy sources and sinks of the climate system are obtained directly from the diabatic heating terms, and an approximate estimate of the planetary entropy production is also provided. The rate of material entropy production of the climate system is found to be ∼50 mW m−2 K−1, a value intermediate in the range 30–70 mW m−2 K−1 previously reported from different models. The largest part of this is due to sensible and latent heat transport (∼38 mW m−2 K−1). Another 13 mW m−2 K−1 is due to dissipation of kinetic energy in the atmosphere by friction and Reynolds stresses. Numerical entropy production in the atmosphere dynamical core is found to be about 0.7 mW m−2 K−1. The material entropy production within the ocean due to turbulent mixing is ∼1 mW m−2 K−1, a very small contribution to the material entropy production of the climate system. The rate of change of entropy of the model climate system is about 1 mW m−2 K−1 or less, which is comparable with the typical size of the fluctuations of the entropy sources due to interannual variability, and a more accurate closure of the budget than achieved by previous analyses. Results are similar for FAMOUS, which has a lower spatial resolution but similar formulation to HadCM3, while more substantial differences are found with respect to other models, suggesting that the formulation of the model has an important influence on the climate entropy budget. Since this is the first diagnosis of the entropy budget in a climate model of the type and complexity used for projection of twenty-first century climate change, it would be valuable if similar analyses were carried out for other such models.

Modeling of atmospheric effects on InSAR measurements by incorporating terrain elevation information

We propose an elevation-dependent calibratory method to correct for the water vapour-induced delays over Mt. Etna that affect the interferometric syntheric aperture radar (InSAR) results. Water vapour delay fields are modelled from individual zenith delay estimates on a network of continuous GPS receivers. These are interpolated using simple kriging with varying local means over two domains, above and below 2 km in altitude. Test results with data from a meteorological station and 14 continuous GPS stations over Mt. Etna show that a reduction of the mean phase delay field of about 27% is achieved after the model is applied to a 35-day interferogram. (C) 2006 Elsevier Ltd. All rights reserved.

Effect of acute administration of recombinant human leptin during the neonatal period on body temperature and endocrine profile of the piglet

Background: Leptin is produced predominantly by white adipocytes; in adults it regulates appetite and energy expenditure but its role in the neonate remains to be fully established. Objectives: To examine the effects of acute administration of recombinant human leptin on the endocrine profile and thermoregulation of neonatal pigs. Methods: 24 pairs of siblings (n = 48) were administered with either a single dose (4 mu g ml(-1) kg(-1) body weight) of leptin (L: n = 24) or a placebo (P: n = 24) on day 6 of neonatal life. Rectal temperature was recorded, and tissue samples were taken at 1 (n = 12), 2 (n = 12), 4 (n = 12) or 6 (n = 12) hours post-administration. Plasma concentrations of hormones and metabolites were determined in conjunction with messenger RNA (mRNA) for leptin and uncoupling protein-2. Results: Plasma leptin increased following leptin administration, and differences in concentrations of insulin, thyroxine and non-esterified fatty acids were observed between the two groups. Initially, rectal temperature decreased in L pigs but returned to start values by 1.5 h. This decline in rectal temperature was delayed in placebo animals, resulting in differences between treatments at 1.5 and 2 h. Conclusions: Acute leptin administration alters the endocrine profile of pigs and influences the thermoregulatory ability of the neonate. Copyright (C) 2007 S. Karger AG, Basel.
