Modéliser l’instabilité ? La complexité au service de la décision stratégique
Le guerre en Ukraine paraît approcher un moment-clé : Moscou avance lentement tandis que Kyiv fait face à l’usure démographique, militaire et politique. Les erreurs d’analyse passées, tant russes qu’occidentales, ont fermé des fenêtres de négociation. Aujourd’hui, l’Ukraine doit déterminer s’il faut négocier pour éviter une issue plus défavorable, alors que l’aide occidentale s’érode, que les États-Unis privilégient ses propres intérêts, et que l…
Tranquillity amidst the bustle
The prevailing paradigm in urban public open space (POS) design emphasises fostering social interaction; it overlooks the equally critical need for urban solitude, secrecy and privacy. In this study, we aim to address this gap by contextualising positive solitude (PS) in POSs within high-density urban environments and examining the spatial conditions that shape these experiences, using Hong Kong as a case study. Empirical research methods, includ…
How public open spaces co-construct solitary experiences in densely populated urban environments
Loneliness in high-density cities is increasingly being recognised as a public health crisis, but the role of built environments in shaping the feelings of loneliness and solitary experiences remains underexplored. This study investigates how socio-material networks in Hong Kong's public open spaces (POSs) co-construct solitary experiences and contribute to emotional well-being. Using a mixed-methods approach, including individual-centred behavio…

Making Vulnerability Invisible
Despite the growing body of work on how COVID-19 impacts the use of public space, few studies focused on vulnerable social groups. This article outlines a systematic analysis of the use of public space by migrant domestic workers before and after the pandemic outbreak in Hong Kong. The analysis reveals changes in behavioral patterns, and we discuss them as part of an ongoing conflictual renegotiation of rights and space alongside the dual nature …
Of other waterfront spaces
In recent years waterfronts have progressively become the focus of local administrations, consultancy agencies, and private developers concerned with public health, city branding, and real estate development. Subsequently, they turned into central stages in which cities and societies can be represented, contested, and inverted. However, many questions remain unanswered concerning their capability to function as counter-spaces in the fast-changing…
Pedestrian access to transit in evolution
This article retraces the impact of evolving hegemonic rapid transit planning and design strategies on pedestrian integration between stations and neighbourhoods, using Hong Kong as a longitudinal case. Mixed-methods research, triangulating documentary analysis, spatial analysis, and in-depth interviews, identified six typologies across three historical phases. The findings demonstrate that pedestrian access to transit is spatially heterogeneous,…
Is justice grounded? How expertise shapes conceptual representation of institutional concepts
Using abstract concepts is a hallmark of human cognition. While multiple kinds of abstract concepts exist, they so far have been conceived as a unitary kind in opposition to concrete ones. Here, we focus on Institutional concepts, like justice or norm, investigating their fine-grained differences with respect to other kinds of abstract and concrete concepts, and exploring whether their representation varies according to individual proficiency. Sp…
Learning from Older Adults’ Use of Urban Parks in Hong Kong’s Low-income Areas
Spatial justice, specifically accessibility, Universal Design and the fulfilment of human rights for vulnerable groups are increasingly important issues in urban research and city-level agendas concerning public spaces. Although the development of older adult–friendly urban environments is part of the agenda to promote healthy ageing societies, public spaces (e.g., urban parks) often exclude those in the advanced age group in the community. This …
The Relationship between Creative Self-Efficacy, Achievement Motivation, and Job Burnout among Designers in China’s e-Market
The e-market is prosperous in China, but the factors that stimulate or deter its development remain unclear. This study focuses on designers (interaction, user interface, product, and user experience designers) in the Chinese e-marketplace to examine the relationship between creative self-efficacy (CSE), achievement motivation (including motivation to approach success [MS], and motivation to avoid failure [MF]), and job burnout. Eighty-two questi…
Pedestrianised streets in the global neoliberal city
The Association between Ground Floor Features and Public Open Space Face-To-Face Interactions
With face-to-face interaction proving beneficial for mental health, there is still a paucity of research on the correlation between ground floor features (GFFs), defined here as the features of the ground floor of buildings overlooking a street, and public open space face-to-face interaction density (POSFTFID), defined as the density of human face-to-face interactions in the public open space (POS) adjacent to each building. Is there a correlatio…
