The present study was conducted to validate an adaptation of the Implicit Relational Assessment Procedure (IRAP) as an indirect latency-based measure of sexual orientation. Furthermore, reliability and criterion validity of the IRAP were compared to two established indirect measures of sexual orientation: a Choice Reaction Time task (CRT) and a Viewing Time (VT) task. A sample of 87 heterosexua...

BACKGROUND Low physical activity (PA) is linked to cancer and other diseases prevalent in racial/ethnic minorities and low-income populations. This study evaluated the PA questionnaire (PAQ) used in the Southern Cohort Community Study, a prospective investigation of health disparities between African-American and white adults. METHODS The PAQ was administered upon entry into the cohort (PAQ1)...

The Separability of Split Value (SSV) criterion is a simple and efficient tool for building classification trees and extraction of logical rules. It deals with both continuous and discrete features describing data vectors and requires no user interaction in the learning process. Extensions of methods based on this criterion are presented. They aim at improvement of reliability and efficiency of...

As reliability based methods gain increased acceptance, there is greater opportunity to use scarce resources more efficiently while maintaining a prescribed level of reliability of a structure throughout its service life. The goal is to provide management decisions that will balance lifetime system reliability and expected lifecycle cost in an optimal manner. This study proposes a system reliab...

BACKGROUND Few assessment instruments have examined the nutrition and physical activity environments in child care, and none are self-administered. Given the emerging focus on child care settings as a target for intervention, a valid and reliable measure of the nutrition and physical activity environment is needed. METHODS To measure inter-rater reliability, 59 child care center directors and...

The main aim of this paper is to revisit the curve fitting problem using the reliability of inductive inference as a primary criterion for the ‘fittest’ curve. Viewed from this perspective, it is argued that a crucial concern with the current framework for addressing the curve fitting problem is, on the one hand, the undue influence of the mathematical approximation perspective, and on the othe...

OBJECTIVE To develop and validate a clinical tool based on the biomechanical strategies exhibited by people with hemiparesis due to stroke during the performance of the Timed "Up and Go" test. DESIGN/METHODS The Timed "Up and Go" Assessment of Biomechanical Strategies (TUG-ABS) was developed for subjects with stroke, based on the analyses of 3 sources of information: published evidence; opini...

OBJECTIVE To investigate the reliability and construct and criterion- related validities of the Timed “Up and Go” Assessment of Biomechanical Strategies (TUG-ABS), when used with subjects with hemiparesis due to stroke within clinical settings. DESIGN/METHODS Construct validity was investigated by the following methods: the known groups, convergence, discriminant analyses, and the opinions of...

Multiversioning of objects in an objectbase system provides increased concurrency and enhanced reliability. The last decade has seen proposals for managing transactions in multiversion database systems. A new transaction model, a new correctness criterion, and an architecture that exploit multiple versions in objectbase systems are described in this paper. The architecture contains three main c...

Multi-criterion quantum programming is a new paradigm of decision making for complex systems. Quantum-based multiobjective algorithm utilizes a new representation, called a Q-bit, for the probabilistic representation that is based on the concept of qubits. Evolutionary computing with Q-bit representation has a better characteristic of population diversity than other representations, since it ca...
