In old age, walking difficulty may reduce opportunities to reach valued activity destinations. Walking modifications, e.g., slower pace or using a walking aid, may enable individuals to continue going where they wish, and hence postpone the consequences of the onset of walking difficulties. We studied visited activity destinations (type, distance) among older people with varying degrees of walking limitations. Community-dwelling 75-85-year-old people living in Jyväskylä (N = 901) were asked to state whether they had no difficulty walking 2 km, had modified their walking, or had difficulty walking. On a digital map, participants located physical exercise, attractive, and regular destinations they had visited during the past month. Destination counts and median distance to destinations from home were computed. Participants with intact walking reported higher counts of physical exercise (IRR = 1.45, 95% CI [1.31, 1.61]) and attractive destinations (IRR = 1.23, 95% CI [1.10, 1.40]) than those with walking difficulty and also visited these destinations further away from home than the others (b = 0.46, 95% CI [0.20, 0.71]). Those with walking modifications reported higher counts of physical exercise destinations than those with walking difficulty (IRR = 1.23, 95% CI [1.09, 1.40]). Counts of regular destinations and distance traveled were not associated with walking limitations. Walking modifications may help people with walking difficulty reach destinations further away from home, potentially contributing to their sense of autonomy. For those with walking difficulty, a low count of destinations other than regular destinations, e.g., shops or healthcare facilities, may signal their abandonment of recreational activities and a decrease in their life space, potentially leading to reduced well-being.

Social and spatial mobility have been subject to substantial recent sociological and policy debate. Complementing other recent work, in this paper we explore these patterns in relation to higher education. Making use of high-quality data from the higher education statistics agency (HESA), we ran a set of multilevel models to test whether the local authority areas where young people grow up influence social and spatial mobility into a higher professional or managerial job on graduation. We found entry to these patterns reflect pre-existing geographies of wealth and income, with more affluent rural and suburban areas in South-East England having higher levels of entry to these occupations. Graduates clustered from major cities tended to be spatially immobile and those from peripheral areas further away from these cities show a higher density of long-distance moves following graduation. We also explored the intersection between social and spatial mobility for graduates with the economic geography of Britain, showing that access to high-class occupations is not necessarily associated with long-distance moves across most British districts. Our evidence further suggests that the \'London effect\', where working-class students have higher school attainment than their peers elsewhere, may not continue through to graduate employment.

Infant health problems are a persistent concern across the United States, disproportionally affecting socioeconomically vulnerable communities. We investigate how inequalities in infant health contribute to differences in interneighborhood commuting mobility and shape neighborhoods\' embeddedness in the citywide structure of employment networks in Chicago over a 14-year period. We use the Census Bureau\'s Longitudinal Employer-Household Dynamics\' Origin-Destination Employment Statistics to analyze commuting networks between 2002 and 2015. Results from longitudinal network analyses indicate two main patterns. First, after the Great Recession, a community\'s infant health problems began to significantly predict isolation from the citywide employment network. Second, pairwise dissimilarity in infant health problems predicts a lower likelihood of mobility ties between communities throughout the entire study period. The findings suggest that infant health problems present a fundamental barrier for communities in equally accessing the full range of jobs and opportunities across the city-compounding existing inequalities.

UNASSIGNED: we present a preliminary set of experimental studies that demonstrates device-aided echolocation enabling in blind and visually impaired individuals. The proposed device emits a click-like sound into the surrounding space and returning sound is perceived by participants to infer the surrounding environment.
UNASSIGNED: two sets of experiments were set up to evaluate the echolocation abilities of nine blind participants. The first setup was designed to identify four material types based on the sound reflection properties of materials, such as glass, metal, wood, and ceramics. The second setup was navigation through a basic maze with the device.
UNASSIGNED: experimental data demonstrate that the use of the proposed device enables active echolocation abilities in blind participants, particularly for material identification and spatial mobility.
UNASSIGNED: the proposed device can potentially be used to rehabilitate disabled blind and visually impaired individuals in terms of spatial mobility and orientation.

BACKGROUND: In this study, we analyze the association of social isolation in the first phase of the pandemic with perceived stress among residents of Poland and Italy with a look at how these populations adjust to and comply with implemented regulations, guidelines, and restrictions.
METHODS: Internet survey with Perceived Stress Scale (PSS-10) and questions regarding mobility patterns, attitude, and propensity to adjust toward the implemented measures and current health condition was made among Polish and Italian residents (Cronbach\'s alpha 0.86 and 0.79, respectively). The sample size was 7,108 (6,169 completed questionnaires in Poland and 939 in Italy).
RESULTS: The Polish group had a higher stress level than the Italian group (mean PSS-10 total score 22,14 vs 17,01, respectively; p < 0.01). There was a greater prevalence of chronic diseases among Polish respondents. Italian subjects expressed more concern about their health, as well as about their future employment. Italian subjects did not comply with suggested restrictions as much as Polish subjects and were less eager to restrain from their usual activities (social, physical, and religious), which were more often perceived as \"most needed matters\" in Italian than in Polish residents.
CONCLUSIONS: Higher activity level was found to be correlated with lower perceived stress, but the causality is unclear. Difference in adherence to restrictions between Polish and Italian residents suggests that introducing similar lockdown policies worldwide may not be as beneficial as expected. However, due to the applied method of convenience sampling and uneven study groups, one should be careful with generalizing these results.

Atmospheric particles are a major environmental health risk. Assessments of air pollution related health burden are often based on outdoor concentrations estimated at residential locations, ignoring spatial mobility, time-activity patterns, and indoor exposures. The aim of this work is to quantify impacts of these factors on outdoor-originated fine particle exposures of school children. We apply nested WRF-CAMx modelling of PM2.5 concentrations, gridded population, and school location data. Infiltration and enrichment factors were collected and applied to Athens, Kuopio, Lisbon, Porto, and Treviso. Exposures of school children were calculated for residential and school outdoor and indoor, other indoor, and traffic microenvironments. Combined with time-activity patterns six exposure models were created. Model complexity was increased incrementally starting from residential and school outdoor exposures. Even though levels in traffic and outdoors were considerably higher, 80-84% of the exposure to outdoor particles occurred in indoor environments. The simplest and also commonly used approach of using residential outdoor concentrations as population exposure descriptor (model 1), led on average to 26% higher estimates (15.7 μg/m3) compared with the most complex model (# 6) including home and school outdoor and indoor, other indoor and traffic microenvironments (12.5 μg/m3). These results emphasize the importance of including spatial mobility, time-activity and infiltration to reduce bias in exposure estimates.

The purpose of this study was to examine and quantify spatial mobility among HIV-negative young men who have sex with men (YMSM) within and across high prevalence HIV neighborhoods in New York City (NYC). We completed an analysis with global positioning system (GPS) and survey data to quantify spatial mobility for participants enrolled in the P18 Neighborhood Study (analytic n = 211; 83.4%). Spatial mobility was documented with self-reported survey data and objective GPS data, which was uncorrelated. Nearly one-quarter of participants (26.1%) said that they consider the neighborhood in which they currently live to differ from the neighborhood in which they had sex most frequently. In addition, 62.9% of participants\' GPS points were recorded in NYC ZIP Code Tabulation Areas within the highest quartile of HIV prevalence. Future studies of YMSM populations should be conducted to examine how environments beyond the residential neighborhood can influence sexual health, which may guide HIV prevention services.

Gerontological scholarship has long seen the environment to be a silent partner in aging. Environmental Gerontology, an established approach in Social Gerontology, has shown how the everyday lives of older adults are deeply entangled in socio-spatial environments. Adopting an Environmental Gerontology approach, we explore social and cultural dimensions of the association between out-of-home mobility and wellbeing among older adults in a north western city of India. This was established by combining high resolution time-space data collected using GPS receivers, questionnaire data and time diaries. Following a multi-staged analytical strategy, we first examine the correlation between out-of-home mobility and wellbeing using bivariate correlation. Second, we introduce gender and family structure into regression models as moderating variables to improve the models\' explanatory power. Finally, we use our results to reinterpret the Ecological Press Model of Aging to include familial structure as a factor that moderates environmental stress. Findings emphasize the central role that social constructs play in the long-established relationship between the environment and the wellbeing of older adults.

This article focuses on generational differences in spatial mobility. Assuming that the ability to cope with the social transformations related to growing mobility varies significantly across generations, we use mobile positioning data collected in Estonia during 2014 providing four main indicators, namely, the number of locations visited and the distances between visited locations, within Estonia and abroad. The results indicate that spatial mobility declines linearly with age; however, a high degree of heterogeneity exists within age groups. Whereas the spatial mobility of the most active members of the younger generation takes place mostly within Estonia, among the most active older generation focus their activity beyond its borders. The study reveals \"delayed mobility\" patterns among the most active groups of the older generation and a new \"immobility culture\" among the younger generation in terms of cross-border activities in a transition society.

In this article we carry out the most comprehensive analysis of social and spatial mobility in the UK to date and the first to directly link different dimensions of mobility to processes of social class formation. Using new analytical techniques in this field, we integrate quantitative and qualitative data from the 1958 Birth Cohort Study, combining text-mining and correspondence analysis in order to examine the intersection of geographical and social mobility with class identities. This work reflects a revival of interest in the spatialization of class inequalities, which is connected to policy concerns about the regional dimension of Britain\'s mobility \'crisis\' that have intensified in the wake of the \'Brexit\' vote. We find that the South\'s role as an \'escalator\' region for upward mobility has continued and that the relationship between social and spatial mobility both confirms and qualifies the role of London and the South East in generating inequalities. We show that different migration-mobility transitions are associated with distinctive and contrasting class identity narratives. Those who move from North to South stand out in particular for the way their \'class talk\' reveals the social disorientation that attends their success. The contrasting ways in which other groups express their social identities suggests that the interplay of geographical and social mobilities performs a significant role in regional cultural divisions.
