Música ao vivo e transformação urbana em Lisboa: Entre resistência cultural e turistificação
No full textNas redes sociais, nos folhetos turísticos e nas campanhas promocionais, Lisboa é vendida como um destino irresistível: cidade da luz e das sete colinas, com elétricos fotogénicos, azulejos, miradouros e noites de fado autêntico. Uma cidade onde tradição e modernidade supostamente convivem em harmonia. Mas, por trás desta imagem encantadora, opera-se a transformação de áreas urbanas em versões estilizadas, controladas e “limpas” para consumo turístico, criando uma fachada sedutora que oculta desigualdades e fragilidades [1]. A proliferação de cafés “instagramáveis” e o ruído constante dos tuk-tuks são apenas alguns dos sintomas de uma Lisboa que se vende bem, mas onde viver e criar se torna cada vez mais difícil.info:eu-repo/semantics/publishedVersio
Sovereignty in the global economic order: Histories of OPEC
No full textThis critical review discuss the history of the Organization of Petroleum Exporting Countries (OPEC) through the lens of national resource sovereignty and its place in the evolving global economic order. Drawing on historical accounts and economic analyses, the study methodologically contrasts insider narratives that emphasize anti-colonialism and self-determination with outsider perspectives focused on price-setting and cartel behavior. The analysis traces OPEC’s trajectory from its sovereign aspirations in the 1960s and its economic clout in the 1970s, to the erosion of cohesion under market pressures in the 1980s and 1990s. The shale oil revolution further challenged OPEC’s relevance, revealing limitations in collective action and pricing power. While Saudi Arabia emerged as the de facto dominant producer, other members often prioritized national agendas, eroding OPEC’s unity. Ultimately, the paper reframes OPEC not merely as a price setting institution, but as a dynamic organization shaped by the interplay between sovereignty ideals and global economic forces. This dual perspective shows that the powerful struggle for national sovereignty and liberation from colonial rule in the Middle East was ultimately undermined by the pressures of competitive market forces.info:eu-repo/semantics/publishedVersio
Not even remotely close: How co-location imbalance affects subgroup formation in hybrid teams
Full text linkDespite the substantial proliferation of hybrid work, little has been done to reconcile extant individual- and team-level perspectives. This is problematic because it does not acknowledge how individuals' hybrid work practices constrain team-level interactions and subsequent outcomes. Specifically, the extant literature does not yet capture the complex configurations that result from team members alternating between co-located and remote forms of collaboration and how these may provoke the formation of subgroups within the team. In this conceptual paper, we introduce the construct co-location imbalance, which we define as the disparity in co-location between different combinations of team members, as a way of capturing geographic configurations in hybrid teams. Through illustrative hybrid teamwork archetypes, we demonstrate the meaning and implications of co-location imbalance on subgroup formation. We then map out a nomological network surrounding co-location imbalance and derive testable propositions on its temporal dynamics and antecedents. Our paper concludes with a discussion of our research's theoretical and practical contributions and directions to advance future research on hybrid teamwork.info:eu-repo/semantics/publishedVersio
The origins of monetary policy disagreement: The role of supply and demand shocks
Full text linkWe investigate how dissent in the Federal Open Market Committee (FOMC) is affected by structural macroeconomic shocks obtained using a medium-scale dynamic stochastic general equilibrium model. We find that dissent is less (more) frequent when demand (supply) shocks are the predominant source of inflation fluctuations. In addition, supply shocks are found to raise private sector forecasting uncertainty about the path of interest rates. Since supply shocks impose a tradeoff between inflation and output stabilization while demand shocks do not, our findings are consistent with heterogeneous preferences over the dual mandate among FOMC members as a driver of policy disagreement.info:eu-repo/semantics/acceptedVersio
The role of non-profit organizations in territorial cohesion in cross-border regions
No full textCross-border regions usually suffer from barriers hindering networking and creating contact among people. On a sample of 244 non-profit organizations (NPOs) in the Upper-Rhine region at the French, German, and Swiss borders, the research used partial least squares structural equation modeling (PLS-SEM) to investigate how NPOs contribute to social capital creation and cross-border territorial cohesion, via the reduction of persistent cross-border barriers. Results show that NPOs are similar to other types of stakeholders. They are primarily oriented at the local level, not towards cross-border cohesion. The primary networking and regional social capital creation are implemented throughout business activities. Barriers influencing cross-border territorial cohesion show that NPOs can effectively overcome them. For that, NPOs in all three countries in our sample follow similar values and principles of work.info:eu-repo/semantics/publishedVersio
Temporary or sustainable? Strategic and leadership perspectives on the four-day work week
No full textPurpose
This study aims to investigate whether the four-day work week (4DWW) can function not merely as a human resource policy but as a strategic organizational resource capable of creating sustainable competitive advantage. Addressing a key gap in the literature, it explores the four-day week from a strategic and leadership perspective, contrasting with prior research that has focused primarily on employee well-being and productivity outcomes.
Design/methodology/approach
The study applies the resource-based view (RBV) and the valuable, rare, inimitable and organizationally (VRIO) framework to assess the strategic value, rarity, inimitability and organizational feasibility of this work arrangement. A qualitative design was adopted, based on 20 semi-structured interviews with chief executive officers, managers and directors. Interview data were analyzed using text-mining tools to identify dominant patterns and themes aligned with VRIO dimensions.
Findings
Results reveal divided managerial perceptions: the policy is widely perceived as valuable and rare, but less consistently inimitable or organizationally feasible. This indicates that, in its current stage, the 4DWW represents a temporary competitive advantage with potential to evolve into a sustainable one as organizational capabilities mature.
Research limitations/implications
The research is limited by its single-country sample (Portugal), the early stage of policy adoption and the lack of cross-sectoral comparison. Future research could integrate employee perspectives and quantitative performance indicators to strengthen empirical generalization.
Practical implications
The findings suggest that leadership commitment, communication and strategic alignment are essential for the successful implementation of the 4DWW. Organizations that embed the policy within broader strategic and cultural frameworks may enhance talent attraction, retention and innovation capacity while differentiating themselves in competitive markets.
Social implications
Leadership-driven adoption of reduced working time can support employee well-being, inclusion and gender equality, while promoting healthier work–life integration. However, attention must be given to workload management and sectoral adaptability to prevent unintended inequalities.
Originility/value
This study fills a theoretical and empirical gap by applying the VRIO framework to the 4DWW and reframing it as an intangible strategic resource shaped by leadership behavior and organizational design. It contributes to the literature by linking strategic management and leadership theory with emerging debates on work-time reduction and sustainable competitiveness.info:eu-repo/semantics/acceptedVersio
Enhancing public healthcare through VADER sentiment analysis: A case study on patient complaints
No full textThis study investigates the application of Valence Aware Dictionary and Sentiment Reasoner (VADER), a rule-based sentiment analysis tool, for rapidly analyzing patient complaints in healthcare environments. By leveraging VADER's efficiency in processing free-text data, the research examines how sentiment analysis can support digital transformation and enhance patient experience management. The study assesses VADER's effectiveness in detecting emotional tone within patient feedback, enabling early identification of systemic issues and informing data-driven decision-making. The dataset comprises 63 written complaints collected throughout 2024 from a key surgery service in a 10 000-employee public hospital in Portugal. Sentiment analysis was conducted using Orange text mining tools integrated with VADER. Three core findings highlight VADER's value: (a) its balance of efficiency and accuracy in sentiment classification, (b) its contribution to patient-centered care strategies, and (c) its support for process optimization, particularly in triage and prioritization workflows. These insights demonstrate how sentiment analysis can help build smarter, more responsive healthcare systems through enhanced digital capabilities.info:eu-repo/semantics/publishedVersio
University students’ condom use during the COVID-19 pandemic: Cross-cultural differences and what predict them
No full textHumans instinctively adopt methods to reduce their risk of encountering harmful pathogens, yet their adherence to preventive health practices can often be erratic. Condoms exemplify one vital preventive tool against sexually transmitted infections (STIs) that, despite their effectiveness, are not consistently utilized. This pattern of behavior appears to persist even during periods of widespread disease transmission, with varied data from the COVID-19 pandemic indicating that condom usage remained inconsistent. The present study aimed to clarify these inconsistencies by examining changes in condom use cross-culturally. Heterosexual participants who were sexually active (N = 3,972 [1,327 men, 2,645 women], Mage = 22.82) across 18 countries were asked about their condom use prior to the pandemic, then about their current use. Results revealed a significant decline in Australia, Canada, Portugal, Vietnam, Uganda, and Taiwan. Vaccination percentage and lockdown stringency were associated with this decline cross-culturally. These findings continue to add concerns about the spread of STIs among young people during the pandemic.info:eu-repo/semantics/publishedVersio
Reconfiguring space based on images: Infinite visual atlas of Lisbon’s riverfront
No full textO artigo apresenta a investigação sobre a zona ribeirinha de Lisboa realizada pelo Laboratório Lisboa e o Rio (constituído por 12 estudantes, 1 professor e 2 investigadores), no âmbito do Mestrado Integrado em Arquitetura do Iscte (2020/2021). Com base numa grelha conceptual associada a imagens e constituída por diferentes categorias – Topografia, Fronteira/Limite, Memória, Infraestruturas, Paisagens Frágeis, Ícones, Acontecimentos, Mobilidade, Vida, (In)previsibilidade e Utopia – construímos um atlas visual da zona ribeirinha de Lisboa de modo a compreender o território e dar-lhe novos significados (Laboratório Lisboa e o Rio, 2021a). O objetivo central foi perceber a origem e evolução do edificado existente e as dinâmicas da população ribeirinha, para posterior realização de propostas arquitetónicas de regeneração da linha de costa. O Atlas Mnemosyne, de Aby Warburg (2010), foi a principal referência. A metodologia teve por base pesquisa bibliografia e imagens de arquivos da Câmara Municipal de Lisboa, do Porto de Lisboa, do Museu de Lisboa, da Biblioteca Nacional, entre outros, e de sites e páginas web. Produzir o atlas foi “reconfigurar o espaço, redistribuí-lo, desorientá-lo” (Didi-Huberman, 2010, pp. 6-7), de modo a construir uma geografia alternativa, uma nova forma de ver e dar a ver, associando diferentes matérias que fomos recolhendo ao longo do tempo. Combinar imagens e realizar conexões inesperadas a partir de diferentes categorias que construíam uma linha de pensamento, fez-nos descobrir olhares diferentes sobre a zona ribeirinha e, com isso, criar uma base de investigação para a realização de propostas arquitetónicas de regeneração da linha de costa.The article presents the research on Lisbon’s riverside area carried out by the Lisbon and the River Laboratory (12 students, 1 professor and 2 researchers), as part of the Integrated Master’s Degree in Architecture at Iscte (2020/2021). Based on a conceptual grid associated with images and made up of different categories – Topography, Border/Limit, Memory, Infrastructures, Fragile Landscapes, Icons, Events, Mobility, Life, (In)predictability and Utopia – we built a visual atlas of Lisbon’s riverside area in order to understand the territory and give it new meanings (Laboratório Lisboa e o Rio, 2021a). The main objective was to understand the origin and evolution of the existing buildings and the dynamics of the riverside population, in order to subsequently realise architectural proposals for regenerating the coastline. The Mnemosyne Atlas by Aby Warburg (2010) was the main reference. The methodology was based on bibliographical research and images from the archives of Lisbon City Council, the Port of Lisbon, the Lisbon Museum, the National Library, among others, and from websites. Producing the atlas meant ‘reconfiguring space, redistributing it, disorientating it’ (Didi-Huberman, 2010, pp. 6-7), in order to build an alternative geography, a new way of seeing and making visible, associating different materials that we have collected over time. Combining images and making unexpected connections from different categories that built a line of thought, allowed us to discover different views of the riverside area and, with this, create a research base for the realisation of architectural proposals for the regeneration of the coastline.publicad
Do health care professionals trust parents? A team ethnography of childhood vaccine hesitancy from seven European countries
No full textSocial-scientific scholarship on vaccination has often stressed the importance of trust. Vaccine hesitancy has commonly been viewed as determined by the degree of trust that parents have in expert knowledge, health care authorities, and health care professionals (HCPs). Focusing primarily on parents as trustors, the bilateral nature of trust and HCPs’ trust in parents have seldom been considered. This article systematically explores these commonly overlooked aspects of trust-building. Drawing on a team ethnography in seven European countries consisting of 466 hours of observations, 167 in-depth interviews with vaccine-hesitant parents, and 171 in-depth interviews with HCPs, this article explores the levels, expressions, and outcomes of trust in the vaccination context. We suggest that trustful relationships are influenced by interpersonal and generalized trust and expressed through both the affective and cognitive dimensions. We further explore interactions where HCPs’ (dis)trust may mitigate vaccine hesitancy. We conclude by providing policy implications for education, campaigns, and interventions.info:eu-repo/semantics/publishedVersio
