The management of urban sprawl is fundamental to achieving sustainable urban development. Monitoring urban sprawl is, however, challenging. This study proposes the use of two spatial statistics, namely global Moran and local Moran to indentify statistically significant urban sprawl hot and cold spots. The findings reveal that the Moran indexes are sensitive to the distance band spatial weight m...

CONTEXT AND OBJECTIVE Alzheimer's disease is a common cause of dementia and identifying possible spatial patterns of mortality due to this disease may enable preventive actions. The objective of this study was to identify spatial distribution patterns of mortality due to Alzheimer's disease in the state of São Paulo. DESIGN AND SETTING Ecological and exploratory study conducted in all municip...

an upward trend in the divorce rate in iran in recent years has attracted officials, researchers and sociologists towards investigating causes and factors contributing such a social menace. based on the statistics published by the statistics center of iran (sci), the divorce rate has gone up from 1.5 in 1000 cases in 1996 to 2.3 in 1999 and 3.1 in 2006. results of previous studies show that fac...

BACKGROUND The Samburu region of northern Kenya is undergoing significant change, driven by factors including greater value on formal education, improvements in infrastructure and development, a shift from community to private ownership of land, increased sedentary lifestyles and global climate change. One outcome of these changes are an increasingly greater likelihood for adolescent boys to be...

Starting from any graph on $\{1, \ldots, n\}$, consider the Markov chain where at each time-step a uniformly chosen vertex is disconnected all of its neighbors and reconnected to another vertex. This has stationary distribution whose support set non-empty forests n\}$. The random forest corresponding this interesting connections with uniform rooted labeled tree attachment tree. We fully charact...

The relationship between the M-species stochastic Lotka-Volterra competition (SLVC) model and the M-allele Moran model of population genetics is explored via timescale separation arguments. When selection for species is weak and the population size is large but finite, precise conditions are determined for the stochastic dynamics of the SLVC model to be mappable to the neutral Moran model, the ...
