We have developed Phylo-VISTA (Shah et al., 2003), an interactive software tool for analyzing multiple alignments by visualizing a similarity measure for DNA sequences of multiple species. The complexity of visual presentation is effectively organized using a framework based upon inter-species phylogenetic relationships. The phylogenetic organization supports rapid, user-guided inter-species co...

This paper gives the SNAP and SPAN ontologies relating to recognizing variable vista spatial environments, namely, SNAPVis and SPANVis. It proposes that recognizing spatial environments is a judgment process of whether the perceived environment is compatible with the remembered one. Their compatibility is based on both their spatial changes and the commonsense knowledge of objects’ stabilities....

Current advances in test development theory have mostly been influenced by item response theory. Notwithstanding this, classical test theory still plays a major part in the development of tests for applied educational and behavioral research. This article describes ViSta-CITA, a computer program that implements a set of classical item and test analysis methods that incorporate innovative graphi...

Questo paper presenta i primi esiti di un progetto di ricerca ancora in corso che mira a esplorare nuove forme di scrittura e rappresentazione etnografica. In particolare, la diffusione di tecnologie e pratiche di geo-tagging ha consentito di creare una piattaforma mediale plurale, in cui le tante soggettività che hanno osservato un complesso rituale funerario Bororo (nel Mato Grosso brasiliano...

When people have visual access to the same space, judgments of this shared visual space (shared vista) can facilitate communication and collaboration. This study establishes baseline performance on a shared vista task in real environments and draws comparisons with performance in visually immersive virtual environments. Participants indicated which parts of the scene were visible to an assistan...

Introduction The total dietary Ca requirement for broilers has previously been determined using limestone, monoor di-calcium phosphate, and in the presence of dietary phytate (Bar et al., 2003). Phytate has been reported to increase the total dietary Ca requirement of chickens from 0.50% to 0.95% (Nelson et al., 1968). The use of exogenous phytase promotes phytate hydrolysis and allows for a ma...
