The impact of pollution on cultural heritage in the Historic Centre of Porto, Portugal
2024-03-25 - Silva, Fátima Matos; Arreiol, Marta; Fragata, Ana
Pollution is a constant threat to cultural heritage, mainly affecting its constituent materials, and it is urgent to implement mitigation and adaptation measures to prevent pollution. The city of Porto currently has several initiatives that aim to prepare this municipality for climate change adaptation. This article aims to study the impact of pollution on built heritage, as well as the initiatives that are being implemented in the Municipality of Porto (as part of the Portuguese Camino to Santiago) to protect heritage, based on three case studies, namely Carmelitas Church, São João Novo Church, and Vitória Church, contextualising them over time and understanding their structure and materials. The methodology is based on an anomalies survey through local and surrounding photographic records to assess the effects of pollution, following the model developed at Carmo Church in Olinda, Pernambuco. This study’s results showed that the stone facade of Carmelitas Church, which is in a busier area of the city, is much more deteriorated when compared with the other case studies due to the direct impact of pollution.

Green Shocks: The spillover effects of Green Equity Indices on global market dynamics
2024-04-07 - Trancoso, Tiago; Gomes, Sofia
This study investigates the impact of green equity indices on global market dynamics using a time-varying parameter vector autoregression (TVP-VAR) model. We uncover a significant shift in the role of the global market, transitioning from a shock transmitter to a shock receiver, as the influence of green finance grows. By directly comparing green equity indices with their corresponding global parent indices, we adopt a global perspective that transcends the limitations of studies focusing on specific regions, such as the USA, China, or Europe. This novel approach minimizes the potential biases in the transmission channels within regional markets, enabling a more comprehensive understanding of the relationship between green finance and global market dynamics. Moreover, by focusing on equity indices we ensure a consistent comparison of financial instruments, avoiding the complexities that arise when comparing different asset classes such as green bonds and conventional equities. For global investors, our results highlight the importance of dynamic and flexible hedging strategies that adapt to the distinct characteristics of green assets and their growing influence on the global market. Risk managers should incorporate these time-varying spillover effects into their models to better assess and mitigate potential risks. Policymakers should consider the growing influence of green finance on the broader market when formulating regulations and incentives to support sustainable investing, as our findings underscore the increasing importance of this sector in shaping market dynamics.

Técnicas de diagnóstico cualitativo para la regeneración urbana
2024-04-01 - Alcindor, Mónica
El arquitecto, entendido como el responsable de la construcción de artefactos, así como de diferentes modificaciones que definen nuestro medio espacial, tiene una clara influencia en nuestras relaciones a través de las intervenciones que propone. El arquitecto debe tener en cuenta todos los que de un modo u otro se verán afectados con su intervención, sobre todo en el caso de la regeneración urbana como escenario de la vida social. Mediante el uso de técnicas de diagnóstico social es posible acceder a tener una visión poliédrica de las cosmovisiones de todos los actores que forman parte del lugar de intervención. Estas técnicas se basan en que la comprensión del conocimiento de la realidad siempre es poliédrico y se enriquece con la confluencia de distintas perspectivas al mismo tiempo que se fortalece la acción conjunta como comunidad.
