Estrategias y actividades en la sala de aula con las tecnologías de la información y comunicación: un estudio con profesores de la enseñanza básica y secundária en Portugal

En las escuelas portuguesas se han implementado en los últimos años importantes programas de equipamiento y de formación de profesores en Tecnologías de la Información y Comunicación (TIC). La utilización de las tecnologías en contextos educativos, gana todos los días 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, podrá constituir un importante recurso de manera a posibilitar nuevos caminos en la enseñanza y el aprendizaje. Es desde esta perspectiva, que hemos intentado comprender cómo solucionan los profesores los problemas involucrados con la utilización 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 continúan 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 innovación, continúan a existir asimismo algunas dificultades en adaptar los nuevos medios a las nuevas pedagogías.

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.

Profiles of ageing in the South of Portugal: education and cognitive functioning in elderly persons living in institutionalized and community contexts

The region of the Algarve shows huge differences between the coastline where population in the urban areas grows, and the inland rural areas, in some cases very isolated, which frequently have high ageing indexes. This general scenario, with an elderly population with very different economic and social conditions, frames the ongoing PhD research designed as a cross-sectional study of an intentional sample of elderly persons. The basic theoretical framework departs from the perspective of developmental psychology of life-span and the model of selection, optimisation and compensation for optimal ageing (Baltes & Baltes, 1990; Freund & Baltes, 2002). The present study is a first step in the analysis of empirical data collected in the PhD sample (N=156; age range 65 to 97 years; M = 80.4 years; SD = 7.2 years). Its purpose is to assess the cognitive functioning of participants, screening for cognitive impairment and examine the relations between the cognitive status of the subjects and a number of selected variables including educational level, age, physical activity and living contexts of the subjects. We accessed the cognitive status of the participants with the Portuguese version of Mini Mental State Examination (MMSE) finding a 10.3% prevalence of positive cases with cognitive impairment. The results also show significant relationships between the cognitive status accessed by the MMSE and educational level, professional qualification, age, living arrangement and activity level of the participants. The relationship verified between educational level and cognitive status of the participants was the largest correlation found in the study with the variability in educational level accounting for 44.8% of the variability in MMSE score. This results points in the same direction of several lines of research that corroborate the strong intercorrelation between education and cognitive functioning in old age.

Microplankton composition, production and upwelling dynamics in Sagres (SW Portugal) during summer 2001

Microplankton community, production, and respiration were studied alongside physical and chemical conditions at Sagres (SW Portugal) during the upwelling season, from May to September 2001. The sampling station was 5 km east of the upwelling center off Cabo S. Vicente, and 2 km of an offshore installation for bivalve aquaculture.

Sistema de informação para os Indicadores de Monitorização e Previsão da Actividade Turística (IMPACTUR) como experiência para Portugal

Tendo por objectivo apresentar o desenvolvimento de um sistema de informação associado a um caso concreto do sector económico - turismo, o presente artigo resulta do desenvolvimento metodológico de uma componente do projecto de investigação científica denominado IMPACTUR - Indicadores de Monitorização e Previsão da Actividade Turística, sendo este beneficiário da parceria estabelecida entre a Direcção-Geral do Turismo de Portugal e a Universidade do Algarve / Centro Internacional de Investigação em Território e Turismo, aos quais os autores agradecem o apoio concedido. Os SI aplicados ao turismo permitem a criação de ferramentas que possibilitam aos decisores adquirir aquela pequena vantagem essencial para serem os melhores. O sistema de informação IMPACTUR é uma dessas ferramentas, inovadora no panorama português e internacional, a qual disponibiliza informação estatística on-line sobre turismo, em formato electrónico, através de um Web Site acessível a todos os profissionais e investigadores do turismo.
