- Emergência relacionada com o uso de substâncias psicoativas em ambiente recriativo : emergências psicológicas e emergências médicasPublication . Teles, Ana Carolina Carvalho de Oliva; Carvalho, Maria Carmo de AzevedoO presente estudo tem como objetivo descrever as emergências médicas associadas ao uso de substâncias psicoativas em ambiente recreativo com ênfase nos riscos médicos e psicológicos, situações e fatores que levam ao seu agravamento. Esta investigação qualitativa parte de um estudo de caso coletivo onde foram analisados documentos preenchidos pelos profissionais que realizaram a intervenção dos participantes atendidos num serviço de emergência psicadélica de um festival de música e cultura psicadélica em Portugal, no ano de 2023. Num total de 409 casos atendidos no serviço de emergência psicadélica, 36 encontravam-se em emergência médica, sendo que houve a necessidade de reencaminhamento para serviços médicos mais especializados em 10 casos. Nesta amostra (n=36), os resultados evidenciam uma marcada tendência pelo policonsumo e sobredosagens, práticas que se apresentam como fatores de risco para consequências adversas pelo impacto que tem, simultaneamente, nos diversos sistemas do organismo. Concluiu-se que as principais alterações a nível do estado mental e físico são uma agitação psicomotora, delírios, humor ansioso, conteúdo do pensamento desorganizado, inquietação grave e consciência deprimida. Assim, ansiolíticos e antipsicóticos foram as principais medicações administradas e as principais estratégias de intervenção foram de suporte psicológico e fornecer um espaço com baixa estimulação para descansar.
- A predestinação do Homem à filiação divina em Cristo na perspetiva de Ruiz de la Peña e Luis LadariaPublication . Culembe, Jacob Francisco; Martins, António Manuel AlvesEste trabalho sobre a predestinação do Homem à filiação divina feito a partir de duas obras de Antropologia teológica dos autores, Ruiz de la Peña e Luis Ladaria, procura desenvolver a filiação divina no horizonte de uma criação em Cristo, cuja mediação se encontra na criação e na redenção. Jesus, mediante a sua encarnação, uniu-se a cada ser humano, para o fazer participar da sua divindade, ou seja, da sua filiação divina. Ainda mais, o próprio Filho de Deus, para realizar o desígnio do Pai, entregou também a sua vida na cruz a fim de redimir o pecado do ser humano. Por isso, mediante a encarnação e a justificação de Cristo, abre-se de novo ao Homem, através da fé e do batismo, a vida de comunhão e de filiação em Deus pela ação do Espírito Santo. O Homem, na vivência do dom gratuito da graça de Cristo, é verdadeiramente filho de Deus e, uma vez unido a Cristo, entra na fraternidade com todos os seres humanos.
- The power of the yield curve prediction : an analysis of the yield curve prediction for recessions in the eurozone between 2004 and 2024Publication . Schuch, Raphael; Silva, JoanaThis dissertation examines the predictive power of the yield curve (10Y-3M spread triple-A rated government bonds) as a leading indicator of recessions in the Eurozone in the period 2004- 2024. In the economic literature, an inverted yield curve is considered a reliable signal of impending recessions but the monetary policy interventions of the European Central Bank (ECB) after the 2008 financial crisis may have distorted this relationship. Probit models are used to analyze whether the 10Y-3M spread continues to have significant predictive power for recessions and to what extent macroeconomic indicators such as inflation (HICP) and economic growth (GDP growth) influence this effect. The results show that the spread continues to act as a leading indicator for recessions, but that its predictive power was weakened after 2008. In addition, the analysis shows that strong economic growth reduces the predictive power of the spread, while high inflation strengthens this effect. Robustness tests, including a logit model, time lags (t-3, t-6), an AUC-ROC and McFadden R² test, confirm that while the yield curve remains a useful indicator, it should no longer be considered in isolation. The results have far reaching implications for monetary policy and financial markets: the ECB should take greater account of alternative indicators such as labor market and credit market data, while investors should include additional macroeconomic factors in their recession forecasts.
- Equity valuation : the Sage groupPublication . Dário, Martin Caribe; Martins, José TudelaThis dissertation aims to estimate the share price of The Sage Group (LON:SGE), a prominent player operating in the enterprise resource planning software (ERP) market for small and medium-sized businesses, as of November 27th 2024. The objective of the valuation is anchored on ultimately providing a “buy”, “hold”, or “sell” recommendation after a thorough analysis of macroeconomic factors, market conditions, competitive dynamics, and company-specific data. The target price is derived from four valuation approaches: Discounted Cash Flow (DCF), forward P/E multiple, forward EV/S multiple, and forward EV/EBITDA multiple, with the DCF model constituting the primary driver (80% weighting) and subject to sensitivity analysis. The DCF valuation yields a target price of GBX 1,324, with a sensitivity range between GBX 1,039.61 and GBX 1,817.53, reflecting potential variations of -22% to +37% under fluctuations of +/- 1 percentage point in WACC and +/- 0.5 percentage points in the terminal growth rate. The relative valuation methods yield a lower target price: GBX 746 from the forward P/E ratio, GBX 1,132 from the forward EV/S, and GBX 926 from the forward EV/EBITDA multiple. The resulting Sage target price per share amounts to GBG 1,246, representing a slight downside of -3% relative to the November 27th 2024 trading price of GBX 1,303 and a -4% downside compared to the GBX 1,290 target from HSBC. Therefore, considering all factors, this dissertation issues a “hold” recommendation.
- Challenges and opportunities in AI adoption for small and medium-sized family firms : a strategic analysisPublication . Künne, Nick-Marvin; Dinis, LilianaArtificial Intelligence (AI) is reshaping industries, yet small and mediumsized family firms often struggle to unlock its potential. Many familyowned SMEs resist change, face financial constraints, and lack AI expertise, which makes AI adoption a complex challenge. This study examines the unique hurdles family businesses encounter and offers a structured framework to help owners, successors, and consultants navigate AI integration effectively. Using a qualitative approach, this research combines indepth expert interviews with a systematic literature review. Insights from various participants, including family firm owners, successors, nonfamily managers, AI specialists, and consultants, provide a wellrounded perspective on both the obstacles and opportunities of AI adoption. Findings reveal that financial constraints, generational resistance, and risk aversion frequently slow down AI implementation. However, family firms also have key advantages, such as agility, strong stakeholder relationships, and a longterm vision. These advantages, when leveraged strategically, can drive successful AI adoption. These strengths can help improving efficiency, decisionmaking, and competitive positioning. To address adoption challenges, this study presents a phased framework that prioritizes leadership commitment, alignment with family values, workforce training, gradual implementation, and ongoing adaptation. By following this structured approach, family firms can integrate AI in a way that enhances competitiveness while preserving their traditions and core identity.
