Recently, Yamashita and Fukushima [11] established an interesting quadratic convergence result for the Levenberg-Marquardt method without the nonsingularity assumption. This paper extends the result of Yamashita and Fukushima by using l k ¼ kF ðx k Þk d , where d 2 ½1; 2Š, instead of l k ¼ kF ðx k Þk 2 as the Levenberg-Marquardt parameter. If kF ðxÞk(More)
In this paper, we present a new trust region method for nonlinear equations with the trust region converging to zero. The new method preserves the global convergence of the traditional trust region methods in which the trust region radius will be larger than a positive constant. We study the convergence rate of the new method under the local error bound(More)
The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1(More)
OBJECTIVE To examine the reliability of testing strength in children with juvenile arthritis (JA), and to determine the relationship between strength and function. METHODS Children with JA were tested for grip and pinch strength (n = 32). Isometric force produced by hip abductors and knee extensors was tested with a hand-held dynamometer (n = 29). Two(More)
Before the developmental trajectory, outcomes, and related interventions of gratitude can be accurately and confidently studied among the youth, researchers must ensure that they have psychometrically sound measures of gratitude that are suitable for this population. Thus, considering that no known scales were specifically designed to measure gratitude in(More)
