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...

The tremendous increase in smartphone usage is accompanied by an the need for more energy. This preoperational relationship between modern technology and energy generates energy-greedy apps, therefore power-hungry end users. With many apps falling under same category app store, these usually share similar functionality. Because developers follow different design development schools, each has it...

The “Software Package for Aerosol Size Distribution” is a novel graphical user interface application software used for the study of atmospheric aerosol size distribution from various aerosol models (Continental clean, Continental average, Continental polluted, Urban, Desert, Maritime clean, Maritime polluted, Maritime tropical, Arctic, Antarctic) and/or with different aerosol components (insolu...

A common way of classifying network connectivity is the association of the nodal degree distribution to specific probability distribution models. During the last decades, researchers classified many networks using the Poisson or Pareto distributions. Urban infrastructures – like transportation (railways, roads, etc.) and distribution (gas, water, energy, etc.) systems – are peculiar networks st...

Heat stress is one of the most severe climate threats to human society in a future warmer world. The situation is further exacerbated in urban areas by urban heat islands (UHIs). Because the majority of world’s population is projected to live in cities, there is a pressing need to find effective solutions for the heat stress problem. We use a climate model to investigate the effectiveness of va...

1. Description of the Model The model used for this study was GATOR-GCMOM, a parallelized and one-way-nested global-through-urban scale Gas, Aerosol, Transport, Radiation, General Circulation, Mesoscale, and Ocean Model (S1-S12),. The model treated time-dependent gas, aerosol, cloud, radiative, dynamical, ocean, and transport processes. Aerosol processes were treated among a single aerosol size...

this research compared ratings of task performance and contextual performance from three different sources: self, peer, and supervisor. participants were service industry employees in the service industries in yogyakarta, indonesia. a sample of 146 employees and 40 supervisors   from the service industries provided ratings of task performance and contextual performance. the results indicated th...

the logistic regression (lr) method, as an empirical estimation method, was used to model urban growth in gorgan city between the years 1987-2001. three groups of variables including social-economic, land use and biophysical variables were used. similarity among variables is probable. to remove the correlated variables, covariance was calculated and distance to administrative, sporting centers ...

Historically, job analysis has played a fundamental role for developing and validating licensure and certification examinations. Still, research on what constitutes reliable and valid job analysis data is lacking. This paper illustrates several ways to examine the reliability and validity of job analysis survey results. Generalizability theory and the many-facets Rasch model are applied to inve...
