Social competence and career development: validation of a scale with secondary students

This paper presents a validation study of the Perceived Social Competence in Career Scale (SCCarS). The sample included 571 adolescents, 283 girls (49.6%) and 287 boys (50.3%), aged 14 to 25 years old (ì=16.33±1.41), 10th and 11th grade students attending secondary schools in the northern, central and southern Portugal. Exploratory factor analysis indicates the presence of eight factors, with eigenvalues superior to 1.00, explaining 79.16% of the total variance of the items. Confirmatory factor analysis provided support to the factorial structure of eight factors, with adequate fit indices (X2/df=4.229, CFI= 0.909, GFI= 0.869, RMSEA= 0.079, p= 0.000). These results are consistent with the factorial structure found in previous studies carried out with Portuguese samples from 8th grade. Implications are drawn related to the need for further study of the psychometric characteristics of the SCCarS with young people from different age groups

Development of a long-life vacuum-packaged ready-to-eat meat product based on a traditional Portuguese seasoned meat

Carne do alguidar is a Portuguese traditional pork fried meat, usually manufactured for self-consumption purposes. This study developed a ready-to-eat (RTE) meat product, to meet today's consumers’ convenience, manufactured at the industrial scale evaluating its quality and shelf-life, assessing the effect of vacuum packaging and the use of an antioxidant (50 ppm BHT) to enhance oxidative stability. Physicochemical and microbiological parameters were assessed and a sensory analysis was performed. Interestingly, no significant differences were recorded between control (non-BHT) and antioxidant (BHT) samples. Microbiological counts remained at low levels throughout the storage period, ensuring the product’s required microbiological quality. At later storage stages, higher values of thiobarbituric acid reactive substances arose and off flavours and aromas were perceived. Still, overall appreciation was not affected until 12 months storage and a significant depreciation was perceived only after 15 months. Fibrousness and rising of off flavours were negatively correlated with overall appreciation.

Study of different atmospheric environments associated to storms development in the Madeira Island

The study aims to improve the understanding about different atmospheric environments leading to the development of storms associated with heavy precipitation in Madeira Island. For this purpose, four main goals have been considered: 1) To document the synoptic and mesoscale environments associated with heavy precipitation. 2) To characterize surface precipitation patterns that affected the island during some periods of significant accumulated precipitation using numerical modelling. 3) To study the relationship between surface precipitation patterns and mesoscale environments. 4) To highlight how the PhD findings obtained in the first three goals can be translated into an operational forecast context. Concerning the large scale environment, precipitation over the island was favoured by weather systems (e.g, mesoscale convective systems and low pressure systems), as well as by the meridional transport of high amount of moisture from a structure denominated as “Atmospheric River”. The tropical origin of this moisture is underscored, however, their impact on the precipitation in Madeira was not so high during the 10 winter seasons [2002 – 2012] studied. The main factor triggering heavy precipitation events over the island is related to the local orography. The steep terrain favours orographically-induced stationary precipitation over the highlands, although maximum of precipitation at coastal region may be produced by localized blocking effect. These orographic precipitating systems presented different structures, associated with shallow and deep convection. Essentially, the study shows that the combination of airflow dynamics, moist content, and orography is the major mechanism that produces precipitation over the island. These factors together with the event duration act to define the regions of excessive precipitation. Finally, the study highlights two useful points for the operational sector, regarding the meridional water vapour transport and local effects causing significant precipitation over the Island; RESUMO: O estudo procura melhorar o entendimento sobre os diferentes ambientes atmosféricos que favorecem o desenvolvimento de tempestades associadas com precipitação intensa na ilha da Madeira. Nesse sentido foram definidos quatro objetivos: 1) Documentar os ambientes sinópticos e de mesoescala associados com precipitação intensa; 2) Caracterizar padrões de precipitação na superfície, em eventos de elevada precipitação acumulada, utilizando modelação numérica; 3) Estudar as relações entre os padrões de precipitação e ambientes de mesoescala; 4) Mostrar como tais resultados podem ser utilizados num contexto operacional de previsão do tempo. Em relação a ambientes de larga escala, verificou-se que a ocorrência de eventos de precipitação intensa sobre a ilha foi favorecida por sistemas meteorológicos, assim como pelo transporte meridional de humidade por meio de estruturas atualmente denominadas Rios atmosféricos. Neste último caso é de destacar a origem tropical de humidade, no entanto, o seu impacto na precipitação sobre a Madeira durante os 10 invernos estudados [2002-2012] não foi tão elevada. O principal fator que favorece os eventos de precipitação intensa está relacionado com a orografia local. O terreno complexo da ilha favorece a ocorrência de precipitação estacionária induzida orograficamente sobre as terras mais altas, embora a precipitação nas zonas costeiras possa ser produzida por um efeito localizado de bloqueio. Estes sistemas orográficos precipitantes apresentaram diferentes estruturas, associados a convecção pouco profunda e profunda. O estudo mostra que a combinação entre as características do escoamento, a quantidade de humidade, e a orografia são os condimentos essenciais para o desenvolvimento da precipitação sobre a ilha, atuando de maneira a definir as regiões de precipitação excessiva. Por fim, o estudo destaca dois pontos que podem ser úteis na previsão do tempo operacional, ligados a larga escala e aos efeitos locais, os quais podem levar ao desenvolvimento de tempestades e precipitação intensa sobre a ilha.

Positive regional species-people correlations: A sampling artefact or a key issue for sustainable development?

Many studies are documenting positive large-scale species– people correlations (Luck, 2007; Schuldt & Assmann, 2010). The issue is scale dependent: the local association of species richness and people is in many cases a negative one (Pautasso, 2007; Pecher et al., 2010). This biogeographical pattern is thus important for conservation. If species-rich regions are also densely populated, preserving biodiversity becomes more difficult, ceteris paribus, than if species-rich regions were sparsely populated. At the same time, positive, regional species–people correlations are an opportunity for the biodiversity education of the majority of the human population and underline the importance of conservation in human-modified landscapes (e.g. Sheil & Meijaard, 2010; Ward, 2010).

Early Childhood Education For Sustainable Development in Portugal

This chapter reports on the Portuguese trial of the Environmental Rating Scale for Sustainable Development in Early Childhood (ERS-SDEC) scale which was carried out in the context of the initial training of pre-school teachers at the University of Évora and during their practicum in local pre-schools. The particular context of this trial in initial teacher education provides a particular focus on the professional development of the students, and the cooperating teachers provided by their engagement in a collaborative action-research project that was focused upon Education for Sustainable Development. After providing some Portuguese contextual elements related with ESD, we will report on the trial of the scale in Évora and its results in terms of improving the quality of classroom practices and students and teachers professional development provided by their participation in the project. Finally we will share some reflections on the project, the format and use of the scale and on some critical issues that we learned to be critical in terms of ESD in Early Childhood.

The Decent Work Questionnaire (DWQ): Development and validation in two samples of knowledge workers

This research aimed to develop a questionnaire measure of workers’ perceptions of decent work. The initial pool of 72 items covered the substantive elements used by the International Labour Organization to characterize decent work. It was administered to workers from Portugal (N = 636) and Brazil (N = 1039) and submitted to exploratory and confirmatory factor analysis. The final 31-item version yields seven factor scores in addition to the global decent work score. With good reliability, convergent and discriminant validity indices, the DWQ could open new avenues for empirical studies of the decent work concept.

Interdisciplinarity and Design Conceptualisation: Contributions from a Small-Scale Design Experiment

Literature emphasises the sparse research focused in collaborative and open approaches in the design conceptualisation stage, also known as the Fuzzy Front-End (FFE). Presently, the most challenging discussion arising from this specific field of research lies in understanding on whether or not to structure the referred conceptual stage. Accordingly, the established hypothesis behind this study sustains that a structured approach in the FFE would benefit the interdisciplinary dialogue. Therefore, two objectives support this study: to understand the benefits of an interdisciplinary approach in the FFE, and to test one proposed model for this conceptual stage. By means of a small-scale design experiment, this paper pretends to give additional contributions to this area of research, in the context of new product development (NPD). The general research supporting this specific study aims to conceptualise in the area of newly and futuristic aircraft configurations. Hence, this same topic based the conceptualisation process in the conducted ideation sessions, which are conducted by five different teams of three elements each. The results of the different ideation sessions reinforce the contemporary paradigm of Open Innovation (OI), which is based in trust and communication to better collaborate. The postulated hypothesis for this study is partially validated as teams testing the proposed and structured model generally consider that its usage would benefit the integration of different disciplines. Besides, a general feeling that a structured approach integrates different perspectives and gives creativity a focus pervades. Nevertheless, the small-scale of the design experiment attributes some limitations to this study, despite giving new insights in how to better organise coming and more sustained studies. Interestingly, the importance of sketching as an interdisciplinary means of communication is underlined with the obtained results.

Large scale underground energy storage for renewables integration: general criteria for reservoir identification and viable technologies.

The increasing integration of renewable energies in the electricity grid contributes considerably to achieve the European Union goals on energy and Greenhouse Gases (GHG) emissions reduction. However, it also brings problems to grid management. Large scale energy storage can provide the means for a better integration of the renewable energy sources, for balancing supply and demand, to increase energy security, to enhance a better management of the grid and also to converge towards a low carbon economy. Geological formations have the potential to store large volumes of fluids with minimal impact to environment and society. One of the ways to ensure a large scale energy storage is to use the storage capacity in geological reservoir. In fact, there are several viable technologies for underground energy storage, as well as several types of underground reservoirs that can be considered. The geological energy storage technologies considered in this research were: Underground Gas Storage (UGS), Hydrogen Storage (HS), Compressed Air Energy Storage (CAES), Underground Pumped Hydro Storage (UPHS) and Thermal Energy Storage (TES). For these different types of underground energy storage technologies there are several types of geological reservoirs that can be suitable, namely: depleted hydrocarbon reservoirs, aquifers, salt formations and caverns, engineered rock caverns and abandoned mines. Specific site screening criteria are applicable to each of these reservoir types and technologies, which determines the viability of the reservoir itself, and of the technology for any particular site. This paper presents a review of the criteria applied in the scope of the Portuguese contribution to the EU funded project ESTMAP – Energy Storage Mapping and Planning.
