- Modelos locais de governação na educaçãoPublication . Moreira, Ana Gabriela; Alves, José MatiasA transferência de competências na área da educação assume em 2023 um ponto incontornável na agenda das autarquias e das escolas. Quer a nível local, quer a nível territorial os modos de regulação na área da educação poderão corresponder a modelos de domínio e de subordinação, ou de participação, de co-autoria ou regulação sociocomunitária. Estes diferentes modos de regulação, contraditórios e ambíguos, podem colocar em risco o papel do Estado na garantia de justiça, democracia e equidade. O projeto de investigação apresentado para a prova de qualificação da Universidade Católica Portuguesa, no qual pretendemos estudar os diferentes modelos de governação adotados em diferentes municípios, na área da educação, e analisar como é que esses modelos contribuem para o desenvolvimento das pessoas, das organizações e dos contextos locais, foi vertido neste artigo. Através do estudo extensivo de caso, que se pretende realizar nos municípios da Área Metropolitana do Porto, tentaremos abordar os modelos de governação adotados desde o programa Aproximar até hoje. A metodologia a adotar é uma metodologia mista, realizando análise documental, inquéritos por entrevista e questionários. Perspetiva-se que se encontrem várias formas de governação: uma regulação sociocomunitária, uma municipalista, e outra centralista de natureza ambígua, tornando incerto o sentido do desenvolvimento da educação no território.
- Decoding consumer preferences in wine : predictive analytics and machine learning in analyzing Portuguese wine consumer ratingsPublication . Schneider, Lukas Florian; Bertani, NicolòThe increasing significance of electronic markets and platforms has revolutionized how consumers interact with and purchase products such as wine. This change provides more information availability to distinguish it from others. Consequently, it is easier to convey a distinct message for characterful products. Nevertheless, it also results in drawbacks like information overload and a loss of the ability to differentiate. This thesis uses advanced analytics to decode the most important factors for consumer preferences in the Portuguese wine market. At the same time, it addresses the challenges and opportunities presented by the information-rich environment of electronic marketplaces. Specifically, I conducted a study to identify, using predictive analytics tools, the essential qualitative product features of Portuguese wine that matter for consumer satisfaction. To do this, robust predictive models were built using individual consumer review ratings and the descriptive characteristics of Portuguese wines from the electronic marketplace and platform Vivino. Ultimately, relative feature importance was determined using Random Forest, AdaBoost, Gradient Boosting, and XGBoost. Additionally, the study incorporates user comments via topic modeling into the predictive models. As a result of this analysis, the study revealed consumer participation, user engagement, sensory perception, generalization, and price description as driving factors for consumer satisfaction. In summary, all models demonstrated similar outcomes, recommending a focus on extrinsic rather than intrinsic product attributes to differentiate from other product groups. These findings can be used further for strategic market decisions and research.
- Wound-healing potentiation in mice treated with phenolic extracts of Moringa oleifera leaves planted at different climatic areasPublication . Benkiran, Sara; Zinedine, Abdellah; Aziz, Tariq; Rocha, João Miguel; Ayam, Iman Msegued; Raoui, Sidi Mohammed; Chabir, Rachida; Errachidi, Faouzi; Alharbi, Metab; Albekairi, Thamer H.; Alasmari, Abdullah F.For years, Moringa oleifera has been known for possessing wound-healing properties. This study aimed to investigate the effect of two extracts: aqueous extract (AE) and ethanolic extract (EE) of Moringa oleifera leaves planted at two regions (Mssisi and Lamta) in Morocco for their anti-inflammatory and healing properties, for which mice were used as a biological model. Inflammation was monitored by assessing forepaw volume of mice, measured at 0 min, 1 h, 3 h, and 5 h, after its induction by carrageenan. Hind paw of mice were treated with extracts of M. oleifera, at a dose of 50 mg/kg, obtained from Mssisi region. This resulted in reduction of edema by 99.2% with EE and by 91.8% with AE, compared to controls and the phenolic extract of M. oleifera planted at Lamta region. Regarding healing of burns induced on rat’s dorsal region; results showed that application of Moringa-based ointment for 14 days, at a dose of 50 mg/kg on wounds, resulted in total healing, compared to controls (negative control: more than 22 days, and positive control: 22 days). M. oleifera extracts resulted in nearly complete tissue repair of 98.26% and 95.34% with EE and AE, respectively.
