- Stakeholders’ perceptions of new digital energy management platform in municipality of Loulé, Southern Portugal: a SWOT-AHP analysisPublication . Gago, David; Mendes, Paula; Murta, Pedro; Cabrita, Nuno; Ribau Teixeira, MargaridaThis study aimed to develop a multi-stakeholder analysis to identify the best strategies for the integration of a new Digital Energy Management Platform (DEMP). The municipality of Loulé (South of Portugal) was used as a case study. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) framework combined with an Analytical Hierarchy Process (AHP) framework and a TOWS Matrix was employed to analyse the stakeholder’s perceptions to propose strategies for integrating the DEMP. Five focus stakeholder groups were involved. Results showed that stakeholders considered that the positive aspects of DEMP outweigh the negative aspects by approximately 36%. Strengths were ranked with 34.4%, Opportunities with 33.8%, Weaknesses with 20.2%, and Threats with 11.6%. The sequence of factors with the highest overall score by stakeholders was O1(12.7%) > S2(11.1%) > W2(7.4%) > T3(4.1%). Based on stakeholder perceptions, the most suitable strategies were those that use Strengths and Opportunities of the system (SO strategies), and strategies that take advantage of Opportunities while dealing with Weaknesses (WO strategies), achieving a prevalence compared with the other strategies of 34% and 27%, respectively. Therefore, the participation process involving stakeholders’ groups in the implementation and monitoring of the DEMP provided an action plan and consensus capable of meeting the environmental and municipal energy management challenges.
- Determination of essential minerals and trace elements in edible sprouts from different botanical families—application of chemometric analysisPublication . Dobrowolska-Iwanek, Justyna; Zagrodzki, Paweł; Galanty, Agnieszka; Fołta, Maria; Kryczyk-Kozioł, Jadwiga; Szlósarczyk, Marek; Rubio, Pol Salvans; Saraiva de Carvalho, Isabel; Paśko, PawełBackground: elemental deficiency may result in the malfunctioning of human organisms. Sprouts, with their attractive looks and well-established popularity, may be considered as alternative sources of elements in the diet. Moreover, the uptake of micro- and macronutrients from sprouts is better when compared to other vegetable sources. The aim of the study was to determine and compare the level of the selected essential minerals and trace elements in 25 sprouts from different botanical families, to preselect the richest species of high importance for human diets. Methods: the Cu, Zn, Mn, Fe, Mg, Ca determinations were performed using atomic absorption spectrometry with flame atomization and iodine by the colorimetric method. Results: beetroot sprouts had the highest levels of Zn, Fe, and Mg, while onion sprouts were the richest in Mn and Ca, among all of the tested sprouts. Sprouts of the Brassicaceae family were generally richer in Ca, Mg, and Zn than sprouts from the Fabaceae family. Results allow preselection of the most perspective sprouts as possible dietary sources of essential minerals and trace elements. For rucola, leeks, onions, and beetroot sprouts, the data on minerals and trace element compositions were performed for the first time.
- O papel moderador do género na relação entre o workaholism e o conflito trabalho-família/família-trabalho e as suas implicações ao nível do bem-estarPublication . Encarnação, Tiago Filipe Laginha da; Sousa, CátiaAtualmente, são inúmeras as transformações verificáveis nos diferentes setores da sociedade. A família e as expectativas que as empresas colocam sobre os seus funcionários, através das elevadas exigências, são noções que merecem particular atenção, dada a necessidade de estabelecer um ponto de equilíbrio entre estas vertentes de inclusão. A impossibilidade de complementar os domínios familiar e laboral, correlaciona-se fortemente com o workaholism, traduzindo-se esta simbiose em consequências no bem-estar dos trabalhadores. Dado a sua relevância, este estudo de caráter quantitativo, ilustra como principais objetivos: 1) observar o efeito do workaholism sobre o conflito trabalho-família e família-trabalho (CTF-FT); 2) verificar o efeito destas variáveis sobre o bem-estar; 3) observar o papel do género enquanto moderador das relações entre o workaholism e o CTF-FT, o workaholism e o bem-estar, o CTF-FT e o bem-estar; 4) testar a qualidade de ajustamento do modelo proposto. Tendo por base uma amostra constituída por 321 participantes, sendo 187 do sexo feminino e 130 do sexo masculino, com idades entre os 18 e os 68 anos (M = 36.54; DP = 11.67), os resultados evidenciaram que o workaholism e o CTF são preditores significativos do bem-estar e que o workaholism influencia o CTF. Ao nível do género, verificaram-se somente diferenças estatisticamente significativas na variável workaholism e respetivas dimensões, apresentando os homens valores de média superiores comparativamente às mulheres. É imperativo que as empresas atentem à necessidade de estabelecer um conjunto de metodologias, que visem a conciliação entre domínios, prevenindo e evitando comportamentos de excesso e implementando práticas que promovam o bem-estar do seu capital humano.
