Transversalidade e continuidade em educação: um olhar sobre os instrumentos de registo e observação na educação pré-escolar e no 1º ciclo do ensino básico

Tomar consciência do papel do educador de infância e do professor do 1º CEB manifesta-se uma tarefa essencial à prática, permitindo uma orientação da intervenção educativa, no sentido de ir ao encontro do que é esperado por parte destes profissionais. O trabalho espelha as experiências nos contextos de 1º Ciclo do Ensino Básico e de Educação Pré-Escolar, sendo que se encontram evidenciadas as especificidades, transversalidade e continuidade existentes em ambos os contextos. A abordagem do estudo apresenta um caráter misto. Isto é, por um lado um caráter qualitativo, na medida em que procuramos perceber mecanismos, comportamentos e atitudes, por outro lado um caráter quantitativo, na medida em que a informação, recolhida através dos questionários e entrevistas, pode espelhar uma perspetiva quantitativa. O trabalho, comum a ambas as valências, com vista a um incremento na melhoria da intervenção educativa, visa compreender as necessidades, motivações e comportamentos dos sujeitos de estudo. Este estudo tem caraterísticas próximas de uma investigação-ação que permitiram uma avaliação constante da intervenção com o objetivo de a tornar mais eficaz. Os instrumentos e técnicas de investigação utilizados foram a análise documental, as listas de verificação ou controlo, as grelhas de observação, a observação participante, os registos de observação, o inquérito por questionário, a entrevista, os instrumentos de avaliação das aprendizagens, o portfólio de criança, o registo de projeto lúdico e arede curricular. O conhecimento dos grupos de crianças permite atitudes adequadas, assim como uma planificação mais eficaz, na medida em que são promovidas atividades significativas e diferenciadas que vão de encontro às necessidades e interesses de cada um. Estes reguladores da prática educativa são instrumentos que permitem a reflexão, prática sine-qua-non para uma intervenção de qualidade, pois esta ação vai permitir uma avaliação dos acontecimentos e suas consequências e, ainda, a remodelação de práticas e atitudes.

The Interactions between clients and providers of services related to marketing activities

The purpose of this paper is to analyze the business interactions involved in the purchase of services related to marketing activities. We build on the literature about business services classifications and the interaction between clients and providers of business services. An empirical study is conducted by means of a survey questionnaire. Data were collected from a sample of 80 buying firms of services related to marketing activities who agreed to cooperate and represent medium and large Portuguese’s firms. The results show that the buying of services related to marketing activities involves both the client and the provider in the interaction process. This paper contributes to understanding the interaction process of buying services related to marketing activities in terms of the parties involved, product/service exchange, financial and information exchange. Providers of services related to marketing activities can expect stable and preferred relationships if they can offer a good price and quality of service, meet the agreed deadlines and respond quickly to client orders. On the client’s side, the relevance, the characteristics and the wide diversity of services related to marketing activities requires a good understanding and management of the interaction portfolio with providers.

The influence of health expenditures on household impoverishment in Brazil

OBJECTIVE To analyze the variation in the proportion of households living below the poverty line in Brazil and the factors associated with their impoverishment. METHODS Income and expenditure data from the Household Budget Survey, which was conducted in Brazil between 2002-2003 (n = 48,470 households) and 2008-2009 (n = 55,970 households) with a national sample, were analyzed. Two cutoff points were used to define poverty. The first cutoff is a per capita monthly income below R$100.00 in 2002-2003 and R$140.00 in 2008-2009, as recommended by the Bolsa Família Program. The second, which is proposed by the World Bank and is adjusted for purchasing power parity, defines poverty as per capita income below US$2.34 and US$3.54 per day in 2002-2003 and 2008-2009, respectively. Logistic regression was used to identify the sociodemographic factors associated with the impoverishment of households. RESULTS After subtracting health expenditures, there was an increase in households living below the poverty line in Brazil. Using the World Bank poverty line, the increase in 2002-2003 and 2008-2009 was 2.6 percentage points (6.8%) and 2.3 percentage points (11.6%), respectively. Using the Bolsa Família Program poverty line, the increase was 1.6 (11.9%) and 1.3 (17.3%) percentage points, respectively. Expenditure on prescription drugs primarily contributed to the increase in poor households. According to the World Bank poverty line, the factors associated with impoverishment include a worse-off financial situation, a household headed by an individual with low education, the presence of children, and the absence of older adults. Using the Bolsa Família Program poverty line, the factors associated with impoverishment include a worse-off financial situation and the presence of children. CONCLUSIONS Health expenditures play an important role in the impoverishment of segments of the Brazilian population, especially among the most disadvantaged.

Access to continued-use medication among older adults, Brazil

OBJECTIVE To determine the prevalence and associated access factors for all continued-use prescription drugs and the ways in which they can be obtained.METHODS Data was obtained from the 2008 Household National Survey. The sample comprised 27,333 individuals above 60 years who reported that they used continued-use prescription drugs. A descriptive analysis and binary and multiple multinomial logistic regressions were performed.RESULTS 86.0% of the older adults had access to all the medication they needed, and among them, 50.7% purchased said medication. Those who obtained medication from the public health system were younger (60-64 years), did not have health insurance plans, and belonged to the lower income groups. It is remarkable that 14.0% of the subjects still had no access to any continued-use medication, and for those with more than four chronic diseases, this amount reached 22.0%. Those with a greater number of chronic diseases ran a higher risk of not having access to all the medication they needed.CONCLUSIONS There are some groups of older adults with an increased risk of not obtaining all the medication they need and of purchasing it. The results of this study are expected to contribute to guide programs and plans for access to medication in Brazil.

Impact of a price-maker pumped storage hydro unit on the integration of wind energy in power systems

The increasing integration of larger amounts of wind energy into power systems raises important operational issues, such as the balance between power generation and demand. The pumped storage hydro (PSH) units are one possible solution to mitigate this problem, once they can store the excess of energy in the periods of higher generation and lower demand. However, the behaviour of a PSH unit may differ considerably from the expected in terms of wind power integration when it operates in a liberalized electricity market under a price-maker context. In this regard, this paper models and computes the optimal PSH weekly scheduling in a price-taker and price-maker scenarios, either when the PSH unit operates in standalone and integrated in a portfolio of other generation assets. Results show that the price-maker standalone PSH will integrate less wind power in comparison with the price-taker situation. Moreover, when the PSH unit is integrated in a portfolio with a base load power plant, the role of the price elasticity of demand may completely change the operational profile of the PSH unit.

Integration of repositories in Moodle

Current Learning Management Systems focus on the management of students, keeping track of their progress across all types of training activities. This type of systems lacks integration with other e-Learning systems. For instance, learning objects stored in a centralized repository are unavailable throughout an organization for potential reuse. In this paper we present the interoperability features of crimsonHex - a service oriented repository of learning objects - highlighting the use of XML languages. Its nteroperability features are compliant with the existing standards and we propose extensions to the IMS interoperability recommendation, adding new functions, formalizing an XML message interchange and providing also a REST interface. To validate the proposed extensions and its implementation in crimsonHex we designed two repository plugins for Moodle 2.0, the first of which is already implemented and is expected to be included in the next release of this popular learning management system.
