Diversity and difference in the everyday lives of Ugandan street children: The significance of age and gender for understanding the use of space

Childhood is characterised by diversity and difference across and within societies. Street children have a unique relationship to the urban environment evident through their use of the city. The everyday geographies that street children produce are diversified through the spaces they frequent and the activities they engage in. Drawing on a range of children-centred qualitative methods, this article focuses on street children's use of urban space in Kampala, Uganda. The article demonstrates the importance of considering variables such as gender and age in the analysis of street children's socio-spatial experiences, which, to date, have rarely been considered in other accounts of street children's lives. In addition the article highlights the need for also including street children's individuality and agency into understanding their use of space. The article concludes by arguing for policies to be sensitive to the diversity that characterises street children's lives and calls for a more nuanced approach where policies are designed to accommodate street children's age and gender differences, and their individual needs, interests and abilities.

In-street wind direction variability in the vicinity of a busy intersection in central London

We present results from fast-response wind measurements within and above a busy intersection between two street canyons (Marylebone Road and Gloucester Place) in Westminster, London taken as part of the DAPPLE (Dispersion of Air Pollution and Penetration into the Local Environment; www.dapple.org.uk) 2007 field campaign. The data reported here were collected using ultrasonic anemometers on the roof-top of a building adjacent to the intersection and at two heights on a pair of lamp-posts on opposite sides of the intersection. Site characteristics, data analysis and the variation of intersection flow with the above-roof wind direction (θref) are discussed. Evidence of both flow channelling and recirculation was identified within the canyon, only a few metres from the intersection for along-street and across-street roof-top winds respectively. Results also indicate that for oblique rooftop flows, the intersection flow is a complex combination of bifurcated channelled flows, recirculation and corner vortices. Asymmetries in local building geometry around the intersection and small changes in the background wind direction (changes in 15-min mean θref of 5–10 degrees) were also observed to have profound influences on the behaviour of intersection flow patterns. Consequently, short time-scale variability in the background flow direction can lead to highly scattered in-street mean flow angles masking the true multi-modal features of the flow and thus further complicating modelling challenges.

Lighting the homes of people who are visually impaired

An extended research project, funded by the Thomas Pocklington Trust, and carried out by the Research Group for Inclusive Environments (RGIE) at The University of Reading, has examined the lighting found in the homes of people who are visually impaired (VIP). This paper will summarise the results of this substantive study. All the surveyed homes have been occupied by people with sight loss, some of the dwellings were shared with sighted partners. There are several safety issues concerning domestic lighting where inadequate provision may contribute to the incidence of personal injuries occurring in the home. Qualitative and quantitative data from questionnaires, photometric surveys and faceto- face interviews have been obtained from 57 homes. The nature and extent of the visual impairment of each study participant has been identified. This paper will identify important findings from the study, including: a range of areas and tasks within the home that visually impaired people find inadequately lit; the variability of illuminance provided for task lighting and general lighting; and how effective visually impaired people find a selection different lighting systems to those that they commonly use. The research team are able to offer preliminary design guidance for lighting the homes of people who are visually impaired. These will be summarised in the paper.
