When prediction using a diagnostic test outperforms simple prediction using base rates, the test is said to be "clinically efficient," a term first introduced into the literature by Meehl and Rosen (1955) in Psychological Bulletin. This article provides three equivalent conditions for determining the clinical efficiency of a diagnostic test: (a) Meehl-Rosen (Meehl & Rosen, 1955); (b) Dawes (Daw...

Nanoparticles (NPs) are a heterogeneous group of materials that have various applications, and their risk assessment is an essential condition. This study aimed to review the applicable risk assessment methods in occupational and environmental exposures to NPs. A literature search for articles published since 2005 in Web of Knowledge, Scopus, PubMed, Science Direct, and Google Scholar, using ap...

A new research instrument, the MacArthur Structured Assessment of Competencies of Criminal Defendants (MacSAC-CD), was administered to three groups of women defendants: those adjudicated incompetent and committed to forensic hospitals for treatment (n = 38), jail inmates receiving mental health treatment (n = 18) who had not been adjudicated incompetent, and randomly selected jail inmates (n = ...

A small group of individuals with mental illness is repeatedly involved in violence. Little is known about how often and how consistently these high-risk individuals experience delusions or hallucinations just before a violent incident. To address these questions, data from the MacArthur Violence Risk Assessment Study were used to identify 305 violent incidents associated with 100 former inpati...

MacArthur and Wilson's Theory of Island Biogeography (TIB) is among the most well-known process-based explanations for the distribution of species richness. It helps understand the species-area relationship, a fundamental pattern in ecology and an essential tool for conservation. The classic TIB does not, however, account for the complex structure of ecological systems. We extend the TIB to tak...

Most contemporary clinical reasoning tests typically assess non-automatic thinking. Therefore, a test is needed to measure automatic reasoning or pattern recognition, which has been largely neglected in clinical reasoning tests. The Puzzle Test (PT) is dedicated to assess automatic clinical reasoning in routine situations. This test has been introduced first in 2009 by Monajemi et al in the Oly...

Abstract The US campaign for Biak in 1944 was one of the most challenging, albeit little known, operations Pacific war. Major General Horace Fuller’s HURRICANE Task Force faced a tenacious enemy determined to hold island’s three airfields at all costs. Grossly underestimating number Japanese defenders on Biak, MacArthur and Kreuger allocated Fuller only two regimental combat teams initial invas...
