Practices and trends of telework in the Portuguese industry: the results of surveys in the textile, metal and software sectors

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal – supported by IDICT – Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called “hybrid” forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called “traditional” sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called “traditional” sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.

Changing representations and practices in school mathematics: the case of Modern Math in Portugal

The curricular movement known as Modern Mathematics aimed at the transformation of representations and practices in school mathematics. Its study provides us with ways of understanding how these changes came about. The purpose of this paper is to contribute to the understanding of the ways in which representations of school mathematics gradually were influenced by ideas from the Modern Mathematics movement, how these new ideas merged into local educational traditions, and how they were transformed into meaningful practice. This work is centred on the Portuguese context from the middle 1950s to the middle 1960s, and builds on Chervel’s notion of school culture and Gruzinski’s discussion of connected histories.

Knowledge and practices of general practitioners of district Peshawar about schizophrenia

ABSTRACT: Schizophrenia with its disabling features has been placed in the top ten of global burden of disease and is associated with long-term decline in functional ability. General Practitioners not only have an important role in treating patients with an established diagnosis of schizophrenia but they can also contribute significantly by identifying people in early stages of psychosis as they are the first hand medical help available and the duration of untreated psychosis is a good indicator of patient’s prognosis. This cross sectional survey, conducted at the clinics of General Practitioners, was designed to assess the knowledge and practices of general practitioners in Peshawar on diagnosis and treatment of schizophrenia. A semi structured questionnaire was used to assess their knowledge and practices regarding schizophrenia. The Knowledge/Practice was then categorized as good or poor based on their responses to the questions of the administered questionnaire. Overall, the results showed that the knowledge and practices of general practitioners of district Peshawar were poor regarding schizophrenia and may be responsible for delayed diagnosis, inadequate treatment and poor prognosis.

HPV : devem os rapazes ser vacinados?

RESUMO - A infecção por Vírus do Papiloma Humano (Human Papillomavirus - HPV) é uma das doenças de transmissão sexual mais frequentes em todo o mundo. A descoberta de que esta infecção é responsável pelo carcinoma do colo do útero impulsionou o desenvolvimento de vacinas contra o HPV. Em Portugal, a vacina tetravalente contra o HPV faz parte do Plano Nacional de Vacinação, sendo administrada apenas a raparigas aos 13 anos de idade como medida profiláctica do carcinoma do colo do útero. Nos Estados Unidos da América, em Dezembro de 2010, a Food and Drugs Administration (FDA) aprovou o uso da vacina tetravalente na prevenção de lesões pré-cancerígenas e cancerígenas do ânus, tanto em rapazes como em raparigas, dos 9 aos 26 anos. A 25 de Outubro de 2011, o Advisory Committee on Immunization Practices (ACIP) recomendou que todos os rapazes de 11 e 12 anos sejam vacinados contra o HPV com a vacina tetravalente. Partindo desta realidade, o que se pretende com o presente trabalho é compilar evidência científica suficiente que permita ponderar mais aprofundadamente acerca das implicações, a partir de dados epidemiológicos e económicos, de se vacinar ou não os rapazes contra o HPV em Portugal. Em primeiro lugar recolheu-se evidência científica acerca da relação entre a infecção por HPV e o desenvolvimento de carcinomas de diversas regiões anatómicas. Em segundo lugar compilaram-se dados epidemiológicos sobre a incidência e sobrevivência associada aos diferentes tipos de tumores potencialmente associados à infecção por HPV, dando especial ênfase à realidade portuguesa. Em terceiro lugar enquadrou-se sucintamente a história da vacinação contra o HPV em Portugal e as vacinas existentes para prevenir esta infecção. Em quarto lugar foram revistos estudos de avaliação económica da vacinação contra o HPV quer em mulheres quer em homens, após uma introdução ao conceito de avaliação económica do medicamento. Em quinto lugar, foi feita uma estimativa dos custos com a vacinação dos rapazes contra o HPV durante os próximos 20 anos. Por último, procurou-se reflectir acerca das implicações de se alargar ou não a vacinação contra o HPV aos rapazes em Portugal.
