    Interbank syndicated lending
    (2027) Pinheiro, C. M.; Pozzolo, A. F.
    We study syndicated lending among financial intermediaries, focusing on interactions between banks and non-bank financial intermediaries (NBFIs) around the Global Financial Crisis (GFC). Using granular loan-level data for more than 80,000 lender-borrower relationships across more than 100 countries, we decompose the growth of syndicated lending into lender-side and borrower-side components following a matched fixed-effects approach, controlling for differences between domestic and cross-border relationships. We document a marked reallocation of syndicated credit toward NBFIs during the GFC, in both domestic and cross-border markets, driven almost entirely by borrowers’ rather than lenders’ characteristics. These results point to the importance of monitoring non-bank borrowers’ characteristics within the financial sector.

    Navigating climate risk for resilience: A roadmap of research patterns and emerging trends
    (2026) Rebelo, J.; Pereira, H.; Pinheiro, C. M.; Ribeiro, M. F.
    Climate risk has become a defining challenge for business strategy, yet its research landscape remains fragmented across disciplines. This study maps the intellectual structure of climate risk research through a bibliometric analysis enriched with latent Dirichlet allocation (LDA) topic modeling of 2715 peer-reviewed articles. Our analysis first identifies the following six consolidated research patterns: (1) climate adaptation and community resilience, (2) climate risk and insurance mechanisms, (3) climate finance and green investment, (4) climate extremes and scenario modeling, (5) climate impacts and agricultural resilience, and (6) climate mitigation and energy transition. Analysis of the 2020–2024 literature reveals four emerging trends: urban climate adaptation, climate risk and financial stability, extreme climate events and climate modeling, agriculture, food security and household security. The findings indicate a shift toward integrated approaches connecting the physical, social, and financial dimensions of climate risk. The resulting roadmap identifies converging risks and strategic priorities for organizational resilience while providing policymakers with an evolving evidence base to support climate governance and informed decision-making under deepening uncertainty.

    Pseudo-haptics for rover teleoperation enhanced traction loss situation awareness
    (2026) Xavier, R.; Batista, J.; Corujeira, J.; Silva, J. L.; Ventura, R.
    Teleoperation of Unmanned Ground Vehicles (UGVs) in hazardous environments is significantly constrained by the operator’s limited Situation Awareness (SA) regarding locomotion disturbances such as wheel slippage, lateral sliding, and vehicle-stuck states). These subtle physical interactions are often imperceptible through conventional video streams, risking critical mission failure. Active force-feedback haptic interfaces mitigate this, but require the introduction of significant hardware complexity and stability challenges. To overcome these constraints, we propose a novel visual-perceptual approach using Pseudo-Haptic Techniques (PHT) to convey physical vehicle-terrain forces without active force-feedback haptic devices. The primary contributions of this work are: (i) the design, implementation, and integration of three novel PHT visual metaphors (rover wheel dynamics virtual cue representation, screen peripheral border manipulation, and dynamic particle virtual cues flow); (ii) an experimental user study (with 32 participants) linking physical UGV locomotion disturbances directly to real-time PHT visual effects dynamics; (iii) a comprehensive user study evaluating both objective SA performance (disturbance detection and accuracy across Endsley’s perception and comprehension levels) and subjective workload (via NASA-TLX). Statistical results demonstrate that all PHT metaphors significantly enhanced the detection of subtle traction loss compared to standard video feeds, while maintaining equivalent subjective workload and physical discomfort levels. These findings indicate that PHT offers a possible robust, software-defined, low-cost, and stability-safe alternative for enhancing SA in remote robotic operation.
