Estrategias y actividades en la sala de aula con las tecnolog��as de la informaci��n y comunicaci��n: un estudio con profesores de la ense��anza b��sica y secund��ria en Portugal

En las escuelas portuguesas se han implementado en los ��ltimos a��os importantes programas de equipamiento y de formaci��n de profesores en Tecnolog��as de la Informaci��n y Comunicaci��n (TIC). La utilizaci��n de las tecnolog��as en contextos educativos, gana todos los d��as nuevos adeptos entre el profesorado, a pesar de las desconfianzas y de las limitaciones financieras de los centros educativos. La llegada de Internet a la sala de aula, podr�� constituir un importante recurso de manera a posibilitar nuevos caminos en la ense��anza y el aprendizaje. Es desde esta perspectiva, que hemos intentado comprender c��mo solucionan los profesores los problemas involucrados con la utilizaci��n de los nuevos medios que complejizan la sala de aula y con las actividades y estrategias propuestas y realizadas con los alumnos. Cierto es, que contin��an a ser casos puntuales, las experiencias hechas por profesores con las TIC en la sala de aula, pero es interesante observar, que a pesar de los esfuerzos en la innovaci��n, contin��an a existir asimismo algunas dificultades en adaptar los nuevos medios a las nuevas pedagog��as.

Seasonal variations in gross biochemical composition, percent edibility, and condition index of the clam Ruditapes Decussatus cultivated in the Ria Formosa (South Portugal)

The grooved carpet shell clam, Ruditapes decussatus (L. 1758), is one of the most popular and profitable molluscs exploited in rearing plots in the Mediterranean. However, annual catch has been declining steadily since the early nineties. In order to understand the seasonality of its nutritional value, thus providing an improved basis for economical valuation of the resource, gross biochemical composition, percentage edibility and condition index were investigated during a year with monthly periodicity in a commercially exploited population of the clam Ruditapes decussatus in the Ria Formosa, a temperate mesotidal coastal lagoon located in the south of Portugal. Our results show that total and non-protein nitrogen co-varied during the year, resulting in a protein content that peaked in the warmest months. Although complementary in summer, carbohydrate and lipid contents showed irregular annual trends. The observed seasonality was comparable to that shown by studies elsewhere at similar latitudes, and are underpinned by the reproductive cycle of the species. Our results show the clams to be at their prime nutritional value at the beginning of summer, when protein content peaks.

Estimation of unemployment rates in small areas of Portugal: a best linear unbiased prediction approach versus a hierarchical Bayes approach

The high level of unemployment is one of the major problems in most European countries nowadays. Hence, the demand for small area labor market statistics has rapidly increased over the past few years. The Labour Force Survey (LFS) conducted by the Portuguese Statistical Office is the main source of official statistics on the labour market at the macro level (e.g. NUTS2 and national level). However, the LFS was not designed to produce reliable statistics at the micro level (e.g. NUTS3, municipalities or further disaggregate level) due to small sample sizes. Consequently, traditional design-based estimators are not appropriate. A solution to this problem is to consider model-based estimators that "borrow information" from related areas or past samples by using auxiliary information. This paper reviews, under the model-based approach, Best Linear Unbiased Predictors and an estimator based on the posterior predictive distribution of a Hierarchical Bayesian model. The goal of this paper is to analyze the possibility to produce accurate unemployment rate statistics at micro level from the Portuguese LFS using these kinds of stimators. This paper discusses the advantages of using each approach and the viability of its implementation.
