A theory of spatial structure in ecological communities is presented and tested. At the core of the theory is a simple allocation rule for the assembly of species in space. The theory leads, with no adjustable parameters, to nonrandom statistical predictions for the spatial distribution of species at multiple spatial scales. The distributions are such that the abundance of a species at the larg...

Objective: The present study compared results on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) among adult patients with attention-deficit/hyperactivity disorder (AD/HD) and those with Asperger’s disorder (AD).

bispectral index (BIS) value while undergoing emergency kidney transplantation. Few reports have been made on intraoperative pitfall of BIS value associated with seizure. This case report suggests seizure should be taken into account as a reason for such brief fall of BIS, especially while under general anesthesia or in other specific cases in which clinical signs of seizure are unseen. (Korean...

“Which test provides the better measurement of intelligence, the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) or the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV)?” is an important question to professional psychologists; however, it has become a critical issue in Atkins cases wherein courts are often presented with divergent Full-Scale IQ (FSIQ) scores on the WAIS-III...

The present study examined the factor structure of the Wechsler Adult Intelligence Scale--Fourth Edition (WAIS-IV; D. Wechsler, 2008a) standardization sample using exploratory factor analysis, multiple factor extraction criteria, and higher order exploratory factor analysis (J. Schmid & J. M. Leiman, 1957) not included in the WAIS-IV Technical and Interpretation Manual (D. Wechsler, 2008b). Res...

introduction : very severe head trauma cases, defined as glasgow coma scale (gcs) scores of less than 6, have a higher mortality rate and poorer outcome. the purpose of this study was to recognize factors associated with survival and 6-month favorable outcome of very severe head trauma patients presenting to emergency department.  methods: in this historical cohort study, the authors retrospect...

The purpose of this study was to demonstrate the characteristics of the Instrumental Activities of Daily Living (IADL) ability, evaluated by the Assessment of Motor and Process Skills (AMPS), and everyday memory functions (the memory necessary for daily life), assessed by the Rivermead Behavioral Memory Test (RBMT) in elderly people with dementia compared with a community-dwelling group.
