Despite the growth and interest in information processing research, understanding the supporting role of information systems (IS) has been limited. While cognitive processing of information has been examined in learning environments with traditional learning tasks, the investigation of cognitive load within complex simulated IS learning environments has received less attention. Traditional meas...

The explosive growth of the Internet, the widespread use of WWW-related applications, and the increased reliance on client-server architectures places interesting new demands on network servers. In particular, the operating system running on such systems needs to manage the machine's resources in a manner that maximizes and maintains throughput under conditions of extreme load. We propose a new...

The dynamics of range formation are important for understanding and predicting species distributions. Here, we focus on a process that has thus far been overlooked in the context of range formation; the accumulation of mutation load. We find that mutation accumulation severely reduces the extent of a range across an environmental gradient, especially when dispersal is limited, growth rate is lo...

This study investigates the evolution of human growth by analyzing differences in body mass growth trajectories among three populations: the Ache of eastern Paraguay, the US (NHANES, 1999-2000), and captive chimpanzees. The relative growth statistic "A" from the mammalian growth law is allowed to vary with age and proves useful for comparing growth across different ages, populations, and specie...

In this study, we analyzed the relationship between days after planting or growing degree (GDD) and number of labor hours spent on stem training, pruning, harvesting sweet pepper cultivated in commercial glass greenhouses. A model was developed for estimating according to plant height. three large-scale (>1 ha) greenhouse sites (1, 2, 3), weekly growth height, fruit, yield were measured manuall...
