Identifying changes in the spatial structure of cities is a prerequisite for the development and validation of adequate planning strategies. Nevertheless, current methods of measurement are becoming ever more challenged by the highly diverse and intertwined ways of how people actually make use of urban space. Here, we propose a new quantitative measure for the centrality of locations, taking in...

Urban regeneration has proved to be a testing and on-going challenge for both central government and local authorities within the UK and successful solutions have proved to be elusive, at best partial rather than comprehensive and often difficult to sustain. Long-term structural economic decline, the continuing shift from a manufacturing to a service and knowledge based economy, the relentless ...

OBJECTIVES To document current bicycle helmet use in Winnipeg, Manitoba and nearby rural communities, and to identify target groups for a helmet promotion campaign. METHODS Cyclist helmet use was observed between 28 May and 20 August 1996 at a sample of urban and rural locations. Age, gender, helmet use, riding companion(s), location type, correct helmet use, and use of headphones were record...

We followed radio-collared striped skunks (Mephitis mephitis) from January 2004-December 2005 in two urban areas of Flagstaff, Arizona, USA to determine seasonal patterns of movement and home-range size. We also used automated cameras to determine the potential for inter- and intraspecific interaction at skunks' diurnal resting sites and nocturnal focal locations. We found no difference between...

Time location patterns are a significant factor for exposure assessment models of air pollutants. Factors associated with time location patterns in urban populations are typically due to high air pollution levels in urban areas. The objective of this study was to determine the seasonal differences in time location patterns in two urban cities. A Time Use Survey of Korean Statistics (KOSTAT) was...

this study was initiated to characterize urban and peri-urban sheep production systems and their economic importance in and around the towns of debre berhan and dessie, ethiopia. the study was undertaken using group discussions, structured questionnaire and personal observations. in both locations the majority of sheep producers were male household heads and predominantly traders in urban and f...

Existing research suggests that victimization risk is higher among urban residents. Violence against women a notable exception in this trend. While the literature does indicate rural are at equal for violent victimization, it not differentiate between types of non-urban spaces (exurbs, suburbs, small towns, dispersed rural). We use five-category measure rural-urban location articulated land to ...

This paper explores residential and job location patterns and commuting behavior in a monocentric urban model with decentralized employment. We show that, in some cases, identical households choose different residential rings depending on their workers’ job locations. This means that high-income households whose workers work near the central business district (CBD) may choose residential locati...

Measurement of intertidal rock assemblages was investigated as a potential biological indicator to provide a quantitative estimate of the impact of urbanised catchment discharge on the estuaries of Sydney, Australia, from 1995 to 1999. Based on the presence and characteristics of adjacent human activities, sampling locations were categorised as: Bush; Urban; Urban with Sewer Overflows; and Indu...
