This paper examines the spatiotemporal pattern of urbanization in Kathmandu Valley using remote sensing and spatial metrics techniques. The study is based on 33-years of time series data compiled from satellite images. Along with new developments within the city fringes and rural villages in the valley, shifts in the natural environment and newly developed socioeconomic strains between resident...

Recent empirical work suggests that declining industries lobby more successfully for policy concessions than do growing industries. This paper presents a novel and simple explanation for this phenomenon. It is shown that an industry in decline is constrained in its ability to raise revenue through production and therefore has a greater incentive to protect profits by lobbying for more favorable...

We consider the distribution of economic activity within a country in light of three leading theories – increasing returns, random growth, and locational fundamentals. To do so, we examine the distribution of regional population in Japan from the stone age to the modern era. We also consider the Allied bombing of Japanese cities in WWII as a shock to relative city sizes. Our results support a h...

We use a novel kernel estimator with a spatially adaptive smoothing bandwidth to visualise the spatial pattern of Salmonella risk determined from testing in the Danish swine Salmonella control programme. This approach improves on previous methods by allowing focussed estimation of risk in areas of high population density while maintaining stable estimates in regions where the data are sparse. T...

Previous research has shown that forest roads are an important feature in many landscapes and have significant effects on wildfire ignition and cessation. However, forest road effects on burn severity have not been studied at the landscape level. Therefore, the overarching goal of our study is to identify the influences of road edge effects on the spatial patterns of burn severity. We analyzed ...

This paper explores an addition to theory in urban geography pertaining to spatio-temporal dynamies. Remotely sensed data on the historical extent of urban areas were used in a spatial metrics analysis of geographical form of towns and cities in the Central Valley of California (USA). Regularities in the spatiotemporal pattern of urban growth were delected and characterized over a hundred year ...

Remotely sensed images often contain a combination of both pure and mixed pixels. Analysis and classification of remotely sensed imagery used to provide information on the spatial pattern of land cover feature suffer from the problem of class mixing within pixels. Therefore, how to get spatial pattern and boundaries information of endmembers in sub-pixel scale has been receiving increasing atte...

Event-related potentials (ERPs) were recorded while subjects monitored a visually presented sequence of stimuli that provided information about both a temporal pattern (rhythm) and a spatial pattern, and responded to rhythmical or spatial deviants. A third task, which required the monitoring of the same sequence for screen flickers served as a perceptual baseline condition and controlled for re...

A Simple Theory of Industry Location and Residence Choice This paper provides a simple theory of geographical mobility which simultaneously explains people’s choice of residences in space and the location of industry. Residences are chosen on the basis of the utility which mobile households obtain across locations. The spatial pattern of industry is determined by the location decision of a scar...

Present-day surface wind stress climatology is manipulated to simulate wind conditions during the last glacial maximum. These estimated wind fields force a onelayer, wind-driven numerical model of the southern ocean to determine if a change in the strength of the surface wind stress can shift the location of the Antarctic Polar Front, which is part of the Antarctic Circumpolar Current. A change...
