Relaxing or imposing constraints? Exploring the associations between digitalization and space-time flexibilities in Qinghe, Beijing
While information and communications technology (ICT)-based multitasking has become a routine feature of daily activity organization, its implications for space-time constraints remain insufficiently understood. This study develops ICT-based multitasking by distinguishing foreground and background ICT use and examines how different forms of ICT use are associated with perceived temporal and spatial flexibility at the activity and daily levels. Th…
Integrating renewable energy into food supply chains
Purpose Negative electricity prices are becoming more prevalent in European wholesale energy markets, driven by increasing renewable energy integration. This phenomenon, while widely studied in the context of energy systems, remains underexplored in relation to energy-intensive industries, particularly food supply chains. The purpose of this paper is to explore the operational and economic implications of negative electricity pricing on cold chai…
Digitalization Enabling Decoupling of Activities from Traditional Locations in Space and Time
Digitalization has enabled individuals to perform activities partially separated from traditional geographical locations and time of day (i.e., space–time locations), a process referred to as space–time decoupling. Despite decoupling, individuals still occupy space and consume time to perform activities. Therefore, activities involving information and communications technologies (ICTs), or ICT-based activities, might exhibit different patterns of…
Person-based aggregate space-time accessibility (Pasta)
Accessibility is the potential to interact with opportunities. Place-based measures of accessibility, such as gravity-type measures, have been widely applied to compute the opportunities accessible when traveling from a given origin and reflect aggregate geographic patterns of access across a city or region. Despite this, place-based measures are criticized for lacking a consideration of individual-level space-time constraints, which can result i…
Exploring equity implications of online grocery, online restaurant delivery and e-shopping service usage in a suburban context
By examining how different demographics engage with online services, researchers and policymakers can better understand patterns and disparities in their access, usability, and engagement. This study explores the factors driving the frequent usage of online services, particularly online grocery shopping, online restaurant delivery, and e-shopping. By utilizing a representative sample of Scarborough, Ontario, Canada, collected in 2022, this study …
How is grocery shopping completed in households with children? Gender gaps and typologies of grocery shopping in four Canadian metropolises
Grocery shopping is important household labor that directly impacts diet quality and related downstream health outcomes. Like other household tasks, it is usually divided unequally in opposite-gender households, with women doing more grocery shopping than men. However, common indicators used to identify gender gaps, like activity frequency and duration, are unable to sufficiently depict the full picture of the constraints faced by women during gr…
From Displacement to Integration
Proximity-centred accessibility – A conceptual debate involving planning practitioners worldwide
In recent years, the concept of proximity has garnered increasing attention in both transportation research and practice, albeit under various terms and interpretations. Among these, the concept of the 15-minute city has catalysed attention in planning practice, with recent evolution to the x-minute city and city of proximities. In research, proximity-centred accessibility has been offered as an umbrella term to express the ability to reach activ…
Personalizing the dichotomy of fixed and flexible activities in everyday life
Understanding the Hybridization of Everyday Activities from a Time-Geographic Perspective
In contrast to the dichotomous distinction between offline and online activity in much previous research, we argue for hybridization as a key feature of the digitalized postpandemic society, shaping and constraining the everyday lives and activities of individuals in new, unforeseen ways. The current understanding of the complex ways in which hybridization plays out and reorders everyday life is limited, partly due to a lack of relevant conceptua…
From lockdown to precise prevention
Changes in Everyday Internet Use and Home Activity During and After Pandemic‐Related Lockdowns
The outbreak of the COVID‐19 pandemic affected the everyday lives of people. Recent studies have found that Internet use increased during lockdowns and helped people cope with spatial constraints on daily activity. However, long‐term implications on the digitalization of everyday life are still unknown. This study aims to improve the understanding of changes in Internet use during and after lockdown and how these changes relate to home activity a…
Spatiotemporal patterns and mechanisms of street vending from the social sensing perspective
Do spatial factors outweigh institutional factors? Changes in influencing factors of home-work separation from 2007 to 2017 in Beijing
A Multilevel Analysis of Perceived Noise Pollution, Geographic Contexts and Mental Health in Beijing
With rapid urbanization and increase in car ownership, ambient noise pollution resulting from diversified sources (e.g., road traffic, railway, commercial services) has become a severe environmental problem in the populated areas in China. However, research on the spatial variation of noise pollution and its potential effects on urban residents' mental health has to date been quite scarce in developing countries like China. Using a health survey …
