Exquisitor at the Lifelog Search Challenge 2024 : Blending Conversational Search with User Relevance Feedback
(Association for Computing Machinery, Inc, 2024-06-18) Khan, Omar Shahbaz; Sharma, Ujjwal; Zhu, Hongyi; Rudinac, Stevan; Jónsson, Björn Pór; Department of Computer Science
The past decade has seen a rapid expansion of personal and interpersonal multimedia collections. These collections offer a wealth of information about individuals, including their interests, health, and significant life events. While automated techniques can assist in structuring and organizing these collections, they often have limitations in helping users effectively navigate and find relevant items within such large datasets. The Lifelog Search Challenge (LSC) provides a valuable benchmark for evaluating interactive retrieval systems designed for personal multimedia collections. Exquisitor utilizes a large-scale user relevance feedback (URF) approach for searching through large collections. To address challenges in highly descriptive retrieval tasks where the relevance feedback model may fail to identify essential elements, we have enhanced Exquisitor with conversational search capabilities powered by a Vision Language Model (VLM) and refined the features underlying the URF model. Furthermore, Exquisitor has been updated with a streamlined user interface that enables seamless switching between conversational search and URF modes.
Help and support for gambling harm among United Kingdom Armed Forces personnel : A mixed-methods study
(2026-10) Biggar, Blair; Champion, Hannah; Jones, Matthew; Dighton, Glen; Larcombe, Justyn; Fossey, Matt; Dymond, Simon; Department of Psychology
Objectives: To explore the accessibility of mental health and gambling related support within the United Kingdom (UK) Armed Forces and investigate potential barriers to engagement. Methods: We conducted a survey of Armed Forces service personnel (n = 438) and specialist healthcare and welfare staff (n = 94) regarding gambling harm and related challenges. Results: Personnel rarely sought on-base support and recognition of existing service provision was low. Among those who did seek help, healthcare and welfare staff were equally effective in engaging with personnel, with greater professional experience playing a key role in fostering meaningful interactions. Conclusions: Improving access to specialist gambling harm support may enhance help-seeking.
Environmental Sustainability of Hydropower and Its Adaptation to Climate Change
(Springer Science and Business Media Deutschland GmbH, 2026) Patro, Epari Ritesh; Balouchi, Behnam; Gosselin, Marie Pierre; Aparicio, Maria Ubierna; Finger, David Christian; Department of Engineering
Despite the ongoing technological innovation and the rapidly increasing penetration of new renewable energy sources, the hydropower sector managed to remain a central actor for power production worldwide while establishing itself as a strong support to compensate the intermittency induced by most of these new energy sources. However, the sustainability of hydropower is increasingly challenged by climate-induced hydrological shifts, sediment regime changes, and complex socio-environmental trade-offs. This chapter argues that sustainable hydropower in the 21st century demands a holistic, multi-stakeholder approach that integrates climate adaptation, sediment management, ecological integrity, and social equity. Drawing on case studies and modelling examples, the physical foundations, e.g. climate, hydrology, sediment dynamics, and their interconnections with ecosystems and society are highlighted. As a renewable and affordable, usually low-carbon source of energy, hydropower can significantly contribute to the fulfilment of the UN Sustainable Development Goals. However, any hydropower plant also potentially induces important ecological, social, and economic impacts at the local scale, calling for a sustainable strategy in building and management, but also in existing hydropower infrastructures.

In this “centenary” paper, an expert panel revisited Hans Berger's groundbreaking discovery of human restingstate electroencephalographic (rsEEG) alpha rhythms (8–12 Hz) in 1924, his foresight of substantial clinical applications in patients with “senile dementia,” and new developments in the field, focusing on Alzheimer's disease (AD), the most prevalent cause of dementia in pathological aging. Clinical guidelines issued in 2024 by the US National Institute on Aging-Alzheimer's Association (NIA-AA) and the European Neuroscience Societies did not endorse routine use of rsEEG biomarkers in the clinical workup of older adults with cognitive impairment. Nevertheless, the expert panel highlighted decades of research from independent workgroups and different techniques showing consistent evidence that abnormalities in rsEEG delta, theta, and alpha rhythms (< 30 Hz) observed in AD patients correlate with wellestablished AD biomarkers of neuropathology, neurodegeneration, and cognitive decline. We posit that these abnormalities may reflect alterations in oscillatory synchronization within subcortical and cortical circuits, inducing cortical inhibitory-excitatory imbalance (in some cases leading to epileptiform activity) and vigilance dysfunctions (e.g., mental fatigue and drowsiness), which may impact AD patients’ quality of life. Berger's vision of using EEG to understand and manage dementia in pathological aging is still actual.
Circular Economy Practices in Manufacturing SMEs : Exploration of Stakeholder Pressure, Managerial Perception, and the Mediating Role of Circular Economy Orientation
(2025-06-30) Ahmadov, Tarlan; Durst, Susanne; Nguyen, Quang M.; Foli, Samuel; Gerstlberger, Wolfgang; Department of Business and Economics
This study delves into the dynamics of Circular Economy (CE) practices in Small and Medium-sized Enterprises (SMEs), acknowledging their essential contribution to promoting sustainability. As we explore the various influences on SMEs' adoption of CE, we closely examine the distinct impacts of internal and external stakeholder pressure. Additionally, we highlight the role of positive managerial perceptions and introduce a fresh perspective by framing CE orientation as a mediating force. Employing a survey methodology, our data collection spanned three phases, resulting in 196 responses from the Estonian SMEs. The results challenge the assumptions of uniform stakeholder pressures, unveiling nuanced effects on CE practices. Significantly, a heightened CE orientation emerges as a driving factor in enhancing organisational responsiveness to external stakeholder pressure. This study advances our understanding of the intricate relationships between stakeholder dynamics, managerial perceptions, and CE practices, providing valuable insights essential for SMEs to navigate the path towards sustainable practices. This study presents both theoretical and practical contributions and suggests avenues for future research to further explore the multifaceted nature of the relationships uncovered in this study.
