Title     　"Does organisational model affect quality of care?
　　　　　A comparison of for-profit, not-for profit, government run and social
　　　　　enterprise organisations in English social care"
Abstract  This seminar will share research that explores whether organisational
　　　　　model affects care quality. It compares not-for-profit, social enterprise,
　　　　　for-profit and government-run social care (long-term-care)
　　　　　organisations in England. Using England's Care Quality Commission and
　　　　　Skills for Care data alongside qualitative interviews with stakeholders
　　　　　and staff, findings suggest that social enterprises (businesses with a
　　　　　social mission) perform the same or better than any other
　　　　　organisational form. Qualitative insights point to governance,
　　　　　organisational relationships and size as key factors shaping quality
　　　　　outcomes.

Title　　　"AI Governance: The Good, the Bad, and the Uncertain in the EU, US,
　　　　　 and Japan"
Abstract　AI governance has become a central regulatory challenge,
　　　　　 reflecting divergent legal traditions, policy priorities, and risk
　　　　　 perceptions across major jurisdictions. This presentation compares
　　　　　 the European Union, the United States, and Japan, focusing on
　　　　　 the strengths, weaknesses, and uncertainties of their approaches.
　　　　　 The EU advances a comprehensive, precautionary model centered
　　　　　 on fundamental rights and ex ante risk regulation, though it raises
　　　　　 concerns about overregulation and limits on innovation.
　　　　　 The US relies on a fragmented, sectoral, and market-driven
　　　　　 framework that supports flexibility and technological growth but
　　　　　 leaves notable regulatory gaps and uneven protections.
　　　　　 Japan adopts a hybrid, soft-law approach grounded in human-
　　　　　 centric principles and societal trust, yet faces issues of
　　　　　 enforceability and limited global influence. Across these systems,
　　　　　 AI governance reveals deep tensions between individual rights and
　　　　　 collective interests, the resilience of social infrastructures, and
　　　　　 the pursuit of innovation and competitiveness. These tensions
　　　　　 highlight the scale of AI's impact and the difficult trade-offs
　　　　　 involved in balancing safeguards with the drive for technological
　　　　　 leadership. The analysis underscores the need for greater
　　　　　 coordination while preserving legal pluralism in global AI
　　　　　 governance.

Title　　　"Engaging Men and Boys in Sexual and Reproductive Health and
　　　　　 Rights (SRHR) & Gender Equality: Why and How?"
Abstract　Investing in programming and policies to enhance SRHR of women
　　　　　 and girls - in areas such as access to family planning, reducing
　　　　　 child marriage and preventing violence is well understood.
　　　　　 Less well researched, however, is the roles of men and boys.
　　　　　 In this seminar, Prof. Lohan will report on her research conducted
　　　　　 for the WHO examining why this is important and what is the status
　　　　　 of the global research.
　　　　　 She will also report on how SRHR programming can be implemented
　　　　　 with men and boys, including the Jack trial - the largest randomised
　　　　　 trial of school sex education to-date and the first to test boys'
　　　　　 engagement.

Title　　　"Using Mobile Phone Data for Spatial Information Science:
　　　　　 Generation, Inference, and Applications"
Abstract　Mobile phone location data have become an important data source
　　　　　 for spatial information science, offering new opportunities to
　　　　　 observe human activities, mobility patterns, and urban dynamics at
　　　　　 unprecedented spatial and temporal scales. At the same time, their
　　　　　 effective use raises several methodological challenges, including
　　　　　 privacy constraints, limited data accessibility, and the difficulty
　　　　　 of extracting socially meaningful information from raw trajectories.
　　　　　 This talk presents three complementary lines of research addressing
　　　　　 these challenges.
　　　　　 First, I introduce recent work on pseudo trajectory generation,
　　　　　 focusing on AI-driven generative model for GPS trajectory
　　　　　 generation that aims to improve scalability, transportation-mode
　　　　　 diversity, and generation efficiency under privacy-aware settings.
　　　　　 Second, I discuss demographic inference from mobile phone
　　　　　 trajectories, including a Bayesian approach for estimating age
　　　　　 and gender patterns from anonymized mobility data and census
　　　　　 information, with the goal of tracking demographic dynamics in
　　　　　 built environments. Third, I highlight how mobile phone data can
　　　　　 support urban applications by revealing behavioral patterns and
　　　　　 social heterogeneity in cities. Taken together, these studies
　　　　　 illustrate how mobile phone data can contribute not only to
　　　　　 movement observation, but also to data generation, semantic
　　　　　 inference, and evidence building for urban and spatial research.

Title　　　"Graph-Laplacian Modeling of Spatio-Temporal Effects for House-Price
　　　　　 Estimation"
Abstract　Many variables involve the modeling of spatial effects, and their
　　　　　 dynamics over time. This paper presents a linear model in which
　　　　　 spatio-temporal random effects are modeled by graph-
　　　　　 Laplacians. A graph-Laplacian flexibly encodes adjacency in both
　　　　　 space and time, in our case not depending on unknown parameters.
　　　　　 The graph-Laplacian can be input for a prior in a Bayesian estimation
　　　　　 setup, or used as regularization term in a Ridge regression. A spectral
　　　　　 decomposition of the graph-Laplacian significantly reduces
　　　　　 computation time for estimation.
　　　　　 As an application, we estimate graph-Laplacian hedonic pricing and
　　　　　 repeat-sales models on sales prices of Australian residential properties
　　　　　 in the period from 1990 to 2024. Bayesian and Ridge regression
　　　　　 estimation results are very similar, although the computation time for
　　　　　 the Ridge regression is orders of magnitude faster, however at the
　　　　　 expense of missing posterior density functions. Our results highlight
　　　　　 the advantages of graph-Laplacians for predicting individual property
　　　　　 prices and for producing stable, granular price indices, also in thin
　　　　　 markets.

Title　　　"Are Energy Efficiency Improvements Capitalized in Property Prices?
　　　　　 A Hedonic Analysis of Market Incentives"
Abstract　We combine Land Registry and Energy Performance Certificate (EPC)
　　　　　datasets at the micro-level to measure the extent to which energy
　　　　　efficiency improvements in England are capitalized in residential
　　　　　property prices. Using a double imputation hedonic approach?
　　　　　contrary to previous findings? we find that the costs of energy
　　　　　efficiency improvements are only partiallycapitalized in property prices.
　　　　　The capitalization rate is particularly low for detached houses in
　　　　　London. Our benchmark hedonic results are confirmed by robustness
　　　　　checks based on regression discontinuity design, two-stage least
　　　　　squares and repeat-sales.
　　　　　Our results indicate that government interventions are needed to satisfy
　　　　　climate policy goals.

Title　　　"Navigating authenticity and legitimacy in meaningful work:
　　　　　 Repair professionals' experiences in Finland"
Abstract　Authenticity (being true to oneself) and legitimacy (presenting as a
　　　　　competent professional) are closely related concepts central to
　　　　　management, yet their relationship remains unclear. This paper
　　　　　investigates that relationship in the work of repair professionals,
　　　　　where stories embedded in objects of repair carry meaning.
　　　　　Based on interviews and observations, the study reveals that
　　　　　commercial, emotional and material elements influence how these
　　　　　two concepts interact.
