Analytical Derivations of the Neighborhood Effect Averaging Problem ( Neap ) and Its Two Variants
Accurate environmental exposure measurements that maximally mitigate contextual errors are necessary for reliable modeling of human health outcomes. Recent advances in environmental exposure measurements highlight a new manifestation of contextual errors called the neighborhood effect averaging problem (NEAP). This study conceptualizes the NEAP in terms of geostatistical sampling and provides rigorous derivations. We aimed to articulate that the …
The Neighborhood Effect Averaging Problem
The neighborhood effect averaging problem (NEAP) is the problem that individual mobility‐based exposures to environmental factors tend toward the mean level of the participants or population of a study area when compared to their residence‐based exposures. As a result of the NEAP, ignoring people's daily mobility and exposures to nonresidential contexts in geographic or epidemiological studies may lead to erroneous results in the study of mobilit…
Usage of Urban Space and Sociospatial Differentiation of Income Groups
With rapid economic and urban development in recent decades, sociospatial inequalities in Chinese cities are exacerbating. In China, the sociospatial structure of cities has experienced tremendous changes during the economic transition. Based on a person‐based perspective, this study explores the relationship between urban spaces and individual behaviours of low‐income and non‐low‐income groups in general and at the community level. The results i…
Gendered Space‐Time Constraints, Activity Participation and Household Structure
Space‐time constraints imposed by employment and household responsibilities may lead to greater gender differences in individuals’ participation in daily activities. However, few studies have directly examined the impact of household structure on the gender differences in space‐time constraints associated with various daily activities due to the lack of accurate space‐time data. Using a 7‐day GPS‐based activity‐travel diary dataset collected in B…
Gender differences in commute time and accessibility in Sofia, Bulgaria
Much research on human mobility patterns and accessibility to date has been conducted largely in Western European and North American countries, where the private vehicle is the main means for commuting. As a result, most studies focused largely on car-based mobility (automobility) and accessibility, and relatively little is known about countries in other regions of the world. Based on an activity-travel dataset collected in Sofia, Bulgaria and us…
Space–time measures of demand for service
Demand for service in location modelling is often evaluated based on the spatial proximity of fixed and static reference locations of demand (e.g. home) to a facility, which ignores person‐specific activity–travel patterns and the temporal changes in demand for service throughout the day. To address these limitations, this study draws upon recent developments in space–time measures of individual accessibility to explore the spatial and temporal s…
The Internet and the gender division of household labour
Geographers and others have long since examined the distribution of paid work, childcare and housework within households and have more recently begun to explore the various effects of Internet use on everyday life and digital inequalities along lines of gender and other social markers. These lines of inquiry have so far remained largely separate and this paper brings them together by analysing the interrelations between the Internet and the gende…
Using GIS and perceived distance to understand the unequal geographies of healthcare in lower-income urban neighbourhoods
Geographers play important roles in public health research, particularly in understanding healthcare accessibility, utilisation, and individual healthcare experiences. Most accessibility studies have benefited from the increased sophistication of geographic information systems (GIS). Some studies have been enhanced with semi-structured in-depth interviews to understand individual experiences of people as they access healthcare. However, few acces…
Visualisation of Socio‐spatial Isolation Based on Human Activity Patterns and Social Networks in Space‐time
Few previous studies of socio‐spatial isolation have explored both its spatial and temporal dimensions. This study proposes and implemented four visual methods for analysing socio‐spatial isolation using graphic representation of people's social networks and activity patterns in space and time: 3D space‐time paths, time windows, 3D activity density surfaces, and ring‐based visualisation of social networks. These visualisations utilise both activi…
Icts and the Decoupling of Everyday Activities, Space and Time
This article is an introduction to and reflection on the papers about ICTs and everyday life in this issue. It outlines the motivations for the focus on the decoupling of activities, physical space and chronological time and characterises this process and three of its modalities: activity fragmentation; multi‐tasking; and personalised networking. The piece concludes by singling out some common elements that run through the set of papers and by id…
Beyond Difference
Gis methods in time-geographic research
Over the past 40 years or so, human activities and movements in space-time have attracted considerable research interest in geography. One of the earliest analytical perspectives for the analysis of human activity patterns and movements in space-time is time geography. Despite the usefulness of time geography in many areas of geographical research, there are very few studies that actually implemented its constructs as analytical methods up to the…
Individual Accessibility Revisited
Analytical methods for evaluating accessibility have been based on a spatial logic through which the impedance of distance shapes mobility and urban form through processes of locational and travel decision making. These methods are not suitable for understanding individual experiences because of recent changes in the processes underlying contemporary urbanism and the increasing importance of information and communications technologies (ICTs) in p…
Gender differences in space‐time constraints
This study explores gender differences in space‐time constraints and their impact on women's and men's activity‐travel patterns from a time‐geographic perspective. Using a travel diary data set collected in Columbus, Ohio (USA), the time‐budget and fixity constraints of three population subgroups are examined. This paper concludes that space‐time constraints have a significant impact on individual's activity‐travel patterns
Gender, the Home-Work Link, and Space-Time Patterns of Nonemployment Activities
Building upon recent theoretical work on the reconceptualized homework link, this study identifies out-of-home, nonemployment activities as another crucial component of the dynamic dependencies between home and work. Using travel diary data from Columbus, Ohio, and GIS-based three-dimensional visualization techniques, I compare the space-time patterns of these activities for three population subgroups. I examine the complex interrelations among w…
Space‐Time and Integral Measures of Individual Accessibility
Conventional integral measures of accessibility, although valuable as indicators of place accessibility, have several limitations when used to evaluate individual accessibility. Two alternatives for overcoming some of the difficulties involved are explored in this study. One is to adapt these measures for evaluating individual accessibility using a disaggregate, nonzonal approach. The other is to develop different types of measures based on an al…
