- Modeling the determinants of sustainable green growth in the menat region: using the dcce-mg approachPublication . Odugbesan, Jamiu; Aghazadeh, Sanaz; Rjoub, Husam; Dantas, Rui; Correia, Anabela; Rita, João; Mata, MárioThe attempt of ensuring that economic growth is becoming greener with additional efficient use of natural capital which is captured in green growth has gained the interest of researchers, but studies in this regard on MENAT countries are scant. Thus, this study attempted to model the determinant factors of green growth in the MENAT countries using data from 1990 to 2019 and employed the Westerlund and Edgerton (2008) panel cointegration test to examine the cointegration among the variables of interest, and employed DCCE-MG technique to establish the significance of the determinant factors, while FMOLS and DOLS were utilized for robustness check. The result from the panel cointegration test revealed an existence of cointegration relationship between the variables in cases of “cross-sectional dependency” and structural breaks, which suggests that the variables move together in the long-run. Moreover, the findings from DCCE-MG estimates revealed that foreign direct investment, economic growth, renewable energy and institutional quality drives sustainable green growth in the MENAT countries, while population was found to exert negative impact on sustainable green growth. The study provides some information that will assist the policymakers in the MENAT countries to balance sustainable green growth, economic growth, internationalization, institutional quality, environmental cost, and population.
- Para vós: um solo coral sobre o lugar onde vivem as memórias: memória, narração e envolvimento interpessoalPublication . Alexandre, Mafalda Pires da Trindade; Rosa, Armando NascimentoEste relatório versa uma narrativa descritiva sobre a experiência de estágio no âmbito do projeto Para Vós. Trabalham-se conceitos como o Teatro Documental, o Biodrama, a identidade, a memória, a coralidade, a ética numa perspetiva comunitária, a cidadania participativa e as potencialidades de transformação no processo teatral. No seguimento, foi feita a recolha de histórias, por via oral, de grupos de avós locais, com quem foram criadas fortes relações, provando que, de facto, é possível estabelecer uma ponte entre o teatro e a comunidade, evidenciado as suas capacidades revigorantes e inclusivas. Estas memórias, quando partilhadas, adquirem a particularidade de gerar elos de ligação, contribuindo para demonstrar a legitimidade das relações de proximidade entre criador e comunidade, entre o espaço de palco e plateia.
- Assessing the value of demand response in microgridsPublication . Gomes, Isaías; Melício, Rui; Mendes, VictorThis paper presents a computer application to assist in decisions about sustainability enhancement due to the effect of shifting demand from less favorable periods to periods that are more convenient for the operation of a microgrid. Specifically, assessing how the decisions affect the eco nomic participation of the aggregating agent of the microgrid bidding in an electricity day-ahead market. The aggregating agent must manage microturbines, wind systems, photovoltaic systems, energy storage systems, and loads, facing load uncertainty and further uncertainties due to the use of renewable sources of energy and participation in the day-ahead market. These uncertainties can not be removed from the decision making, and, therefore, require proper formulation, and the proposed approach customizes a stochastic programming problem for this operation. Case studies show that under these uncertainties and the shifting of demand to convenient periods, there are opportunities to make decisions that lead to significant enhancements of the expected profit. These enhancements are due to better bidding in the day-ahead market and shifting energy consumption in periods of favorable market prices for exporting energy. Through the case studies it is concluded that the proposed approach is useful for the operation of a microgrid.
