Abstract

The EU AI Act (Art. 27) requires deployers of high-risk AI systems to conduct Fundamental Rights Impact Assessments (FRIAs) before deployment, yet the evidence needed for credible assessments is fragmented across incompatible incident repositories, risk vocabularies, and legal texts. We present a reusable Semantic Web-based framework that consolidates this evidence for two high-risk public sector categories: employment and worker management (Annex III(4)) and access to essential public services (Annex III(5)(a)). A curated 150-record corpus is annotated along four axes using keyword, LLM, and hybrid methods and serialised as a SPARQL-queryable knowledge graph of 1,351 RDF triples. Five FRIA demonstration scenarios surface 103 records (68.7% coverage). Evaluation against a 69-record gold standard reveals that LLM-assisted classification of the employment domain achieves only $κ= 0.045$, a cautionary result for automated fairness-related evidence retrieval in this domain. All artefacts are released openly to support adoption by regulators, national authorities, and SMEs.

Who Does Withholding Delay? A Welfare Model of Open-Weight AI Release Under Asymmetric Proliferation

Withholding a dual-use AI model delays only the actors that lack other routes to a comparable capability. If sophisticated adversaries obtain substitutes faster than distributed defenders, restriction can delay defenders more than the adversaries it targets. We compare controlled access, a defender-first window followed by public release, safeguarded open weights, and minimally restricted open weights in a discounted welfare model with actor-specific substitute acquisition. Under exponential acquisition, restriction gives adversaries a positive discounted access advantage exactly when they substitute faster than defenders, and, with equal usefulness, immediate release adds more expected capability at a fixed horizon to the slower-substituting group. Neither result implies that release is preferable, because opportunistic misuse, defensive reach, safeguard friction, and irreversible losses can reverse the ranking. In a linear benchmark, broad release overtakes control above a unique adversary-substitution threshold whenever such a threshold exists, and we derive the probability that selected defenders deploy before both adversary substitution and public release. In a nonlinear implementation, each of the four policies is optimal somewhere in the parameter space. Three nested 2,048-point designs over thirteen inputs show that policy shares depend strongly on the chosen parameter bounds. Release records and cybersecurity reports illustrate the quantities a release review would need to measure and are kept separate from the calibration.

What Personal Information Improves LLM-Based Next-Location Prediction?

Large language models (LLMs) are increasingly used for individual next-location prediction, with personal information easily added to prompts alongside mobility history. Yet the incremental predictive value of such information remains unclear. Using linked sociodemographic records and mobility traces from 5,000 Shenzhen residents, this study separates model responsiveness from predictive value. GPT-5 is the primary model, with GPT-5.5 and Claude Opus 4.6 used for replication. In 1,000 paired prediction instances, models rank 100 candidate destinations with and without age, gender, occupation and income while all other inputs are held fixed. Behavioural history raises top-1 accuracy from 5.6% to 18.5% as prior history increases from zero to six days. By contrast, sociodemographic attributes produce no detectable overall gain, although replacing correct attributes with those of another person reduces accuracy by 5.4 percentage points. Candidate construction also matters, removing distance raises accuracy by 7.7 points under proximity sampling but lowers it by 22.3 points under popularity sampling, with the reversal reproduced across all three LLMs. These findings identify behavioural history as the clearest source of incremental value and show that personal information should be evaluated under matched, explicitly specified conditions before its privacy and governance costs are justified.

Political polarization and mental wellbeing: asymmetric evidence for bidirectionality

A growing body of evidence suggests that political polarization and mental health and wellbeing influence each other. Yet the two directions, how polarization shapes mental wellbeing and how mental wellbeing shapes polarization, remain siloed across disciplines. We review both literatures to evaluate the strength and alignment of evidence for bidirectional effects. We find that the literature varies widely in constructs, measures, and levels of analysis, and that the evidence for the two pathways is asymmetric: links from polarization to mental wellbeing are more direct, grounded in well-developed theoretical frameworks and social-relational mechanisms. In contrast, the reverse pathway is substantially less direct, with studies often examining cognitive and socio-emotional factors, or political outcomes adjacent to polarization rather than polarization itself. We identify clear gaps in the literature highlighting the need for future studies with conceptual clarity, unified frameworks, validated measures, and multilevel designs examining both pathways within the same empirical and theoretical setting.
