Problemática da oferta de competências no Ensino Superior vs Dificuldades sentidas pelos profissionais no desempenho da sua actividade

A transição para uma sociedade sustentável requer um longo e complexo processo de aprendizagem colectiva. O processo em cada actor social exige práticas com regras, assume novas responsabilidades e adquire relativamente novas capacidades. Este artigo envolve a educação/formação de um sector particular que será responsável pelo desenvolvimento de produtos – Designer. A chave da questão reflectida por educadores de designers e explorada neste artigo é: o que deve ser mudado nas capacidades técnicas e criativas do designer para que este possa estar pronto e habilitado para fazer frente às mudanças exigidas numa sociedade cada vez mais desejosa de novos produtos, de produtos de inovação? Como se pode contribuir ao nível da formação de designers para que os mesmos possam adquirir as competências necessárias para dar resposta às constantes necessidades do meio empresarial

Surveying structural change: seminal contributions and a bibliometric account

The main aim of this paper is to provide a comprehensive survey of the economic literature on structural change. Along with an insightful literature review of the seminal contributions in the field, we perform a quantitative analysis that takes into account all the theoretical and empirical articles on the subject that were published from 1969 onwards. This effort to gather the relevant documentation is based on a review of 910 abstracts from articles published in all the economic journals found in the Econlit database over the past forty years. According to our quantitative analysis, structural change analysis received a major boost in the 1990s, with a considerable increase in the number of articles published on the matter. The marked rise in interest seems to be primarily related to the growing concern to find explanations for the process of technological change and its effects on the economy. In the first half of the current decade technological change comprises a predominant area of research, accounting for about one quarter of the articles published. Despite the increased formalism observed in the 1990s, our results further highlight that the bulk of the research in this field remains empirically led. Furthermore, and quite surprisingly, discussions concerning ICTs do not seem to have been translated so far into a substantial increase in research on structural change-related issues.Structural Change; Bibliometrics; Econlit

Does structure influence growth? A panel data econometric assessment of ‘relatively less developed’ countries, 1979-2003

Neo-Schumpeterian streams of research emphasize the close relationship between changes in economic structure in favour of high-skill and high-tech branches and rapid economic growth. They identify the emergence of a new technological paradigm, strongly based on the application of information and communication technologies (ICTs), in the 1970s, arguing that in such periods of transition and emergence of new techno-economic paradigms the relatively less developed countries have higher opportunities to catch-up. Although this debate is theoretically well documented, the empirics seem to lag behind the theory. In this paper, we contribute to this literature by adding illuminating evidence on the issue. More precisely, we relate the growth experiences of countries which had relatively similar economic structures in the late 1970s, with changes occurring in these countries’ structures between 1979 and 2003. The results reveal a robust relationship between structure and (labour) productivity growth, and lend support to the view that producing (though not user) ICT-related industries are strategic branches of economic activity.Structural change, Economic growth, Technical change

Cork Boiling Wastewater Treatment in Pilot Constructed Wetlands

most studies published on the topic of cork boiling wastewater (CBW) treatment or valorization used physico-chemical treatment options rather than biological processes. However, the related costs are high and above those of the biological treatment alternative for wastewaters with similar organic loads but from different sources. Thus, con- structed wetland systems (CWs) can be an alternative to conventional biological treatment systems, namely to activated sludge systems, with the prominent virtues of low construction and operation costs. Until today, there is no study or research published for the treatment of CBW using CW systems. Thus, this investigation is a novelty and included the monitoring over a period of four years of the operation of a horizontal subsurface flow constructed wetland (HSF CW) microcosm-scale system planted with common reeds (Phragmites australis) and filled with light expanded clay aggregates (LECA), as support media for the plants and for biofilm development. The contribution of plants to the treatment was assessed by the comparison with an identical wetland unit without plantation (control bed). After this extended period of operation intended to maximize biomass development and acclimatization, which included stepwise increase of the organic load rate (OLR) up to 8.9 g COD/m2/d, the assessment of the treatment capacity of the system was done by doubling the OLR to 16.4 g COD/m2/d during 200 days.info:eu-repo/semantics/publishedVersio

Complex phenotype of hypercholesterolaemia in a family with both ABCG8 and APOB mutations

Familial Hypercholesterolemia (FH) is the most common of all genetic hypercholesterolaemias with defects in LDLR, APOB and PCSK9 accounting for the majority of cases. However, there are other rare disorders like sitosterolaemia that can present the same phenotype. Both can cause premature atherosclerosis but have distinctive dietetic and therapeutic intervention.N/

Purely transmitting integrable defects

Some aspects of integrable field theories possessing purely transmitting defects are described. The main example is the sine-Gordon model and several striking features of a classical field theory containing one or more defects are pointed out. Similar features appearing in the associated quantum field theory are also reviewed briefly.Comment: 6 pages, to appear in Proceedings of the XVth International Colloquium on Integrable Systems and Quantum Symmetries, Prague, June 200

Water Quality Index In An Urban Watershed

This study aimed to verify the water quality of Ribeirão das Pedras (Stones River), Campinas, São Paulo, Brazil through the implementation of the Water Quality Index (WQI) and comparison with Brazilian legislation (Resolution of the National Environment Council - CONAMA 357/2005), thus being able to initiate discussions about anthropic interferences in watercourses located in urban areas. Ribeirão das Pedras is part of an urban watershed that suffered, and still suffers, from the rapid and intense urban and housing boom, finding its territorial space almost fully occupied. For the execution of this work, six sample points were defined in order to allow a discussion between the land use within their respective drainage area and the results of the WQI applications. The WQI is composed of nine parameters: dissolved oxygen, biochemical oxygen demand, nitrogen, temperature, thermotolerant coliforms, turbidity, phosphorus, pH, and total solids. The first sample point refers to the main watercourse source, four sample points are located throughout the watershed and the last point is located in its base level, at the confluence between Ribeirão das Pedras and its main stem, Ribeirão das Anhumas (Anhumas River). The results of water quality analysis obtained based on the WQI concept were featured as 'GOOD'; however, the isolated analysis of each parameter allows to compare them with the Brazilian legislation, where it appears that none of the points meets all established quality parameters. Thus, it can be concluded that the watercourse suffers significant impacts along its course, probably derived from the use of the surrounding drainage areas. © 2016 WIT Press.1161037104

The Effect of starter Cultures on the Portuguese Traditional Sausage "Paio do Alentejo" in Terms of its Sensory and Textural Characteristics and Polycyclic Aromatic Hydrocarbons Profile

“Paio do Alentejo” is a Portuguese dry-cured sausage, made with meat from the Alentejano pig breed. The main aim of this study is to evaluate the benefits of the use of starter cultures on the quality of the sausage, mainly with regard to its sensory properties, rheological characteristics and PAH profile. Three batches of the product were examined: S1-inoculated with a commercial starter comprising Lactobacillus spp., Micrococcaceae and yeasts; S2-inoculated with a starter comprising Lactobacillus sakei and Staphylococcus xylosus; C-the control batch, was not inoculated. A sensory panel of 12 experts analysed samples in accordance with a descriptive analysis using a structured scale. A Texture Profile Analysis and 16 EPA priority PAHs for dry fermented sausages were performed. Both inoculated batches were well received by the judges, no significant differences being noted between them. The use of S2 led to a slight improvement in terms of cohesiveness. However, the use of starter cultures was not found to influence PAH content
