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...

INTRODUCTION Rural residents generally experience a higher rate of injury than residents in urban settings. This article sought to identify and compare the pattern of injury mortality and hospitalised injury morbidity for urban and rural residents in New South Wales (NSW), Australia. METHOD Hospitalisation data for 1 July 2000 to 30 June 2005 and Australian Bureau of Statistics mortality data...

BACKGROUND The objective of the present work was to compare pollen counts at three different urban locations within a city to each other and to the counts from a fixed trap. This information could be useful to delimit zones in the urbanized part of the city according to the risk of allergic affections. METHODS Aerobiological sampling using portable traps was carried out at three points in urb...

BACKGROUND Urban environments generate constant loud noise, which creates a formidable challenge for many animals relying on acoustic communication. Some birds make vocal adjustments that reduce auditory masking by altering, for example, the frequency (kHz) or timing of vocalizations. Another adjustment, well documented for birds under laboratory and natural field conditions, is a noise level-d...

Excessive unplanned urban growth leads to many vulnerabilities and impacts on urban environments to varying degrees. However, the majority of the extant literature focuses on the problems related to location and socioeconomic conditions, rather than vulnerability processes and related environmental degradation. This paper analyzes the scope of urban vulnerabilities for five rapidly urbanizing a...

OBJECTIVES Early defibrillation in out-of-hospital cardiac arrest (OHCA) is of importance to improve survival. In many countries the number of automated external defibrillators (AEDs) is increasing, but the use is low. Guidelines suggest that AEDs should be installed in densely populated areas and in locations with many visitors. Attempts have been made to identify optimal AED locations based o...

This paper presents some installation and data analysis issues from an ongoing urban air temperature and humidity measurement campaign in Hangzhou and Ningbo, China. The location of the measurement sites, the positioning of the sensors and the harsh conditions in an urban environment can result in missing values and observations that are unrepresentative of the local urban microclimate. Missing...

This article demonstrates a research strategy and prevention methodology for substance using urban youth that incorporates individual, social, and geographical parameters to systematically understand the ecology of risk and protection for urban youth. The primary goal of this study was to describe and analyze substance using and nonusing urban adolescents' social networks; risky and protective ...

Detection of urban area extents by means of remotely sensed data is a difficult task, especially because of the multiple, diverse definitions of what an "urban area" is. The models of urban areas listed in technical literature are based on the combination of spectral information with spatial patterns, possibly at different spatial resolutions. Starting from the same data set, "urban area" extra...
