In this article, the need for an explicit consideration of the environment in order to address everyday competence (EC) in old age is illustrated based on an analysis of the day-to-day challenges of visually impaired older adults. Data are based on a sample of elderly adults suffering from different degrees of visual impairment (visually severely impaired vs blind, each N = 42) and a control gr...

BACKGROUND To investigate whether motives for exercise participation predicted exercise dependence (ED) among endurance athletes. The rationale for the study centred upon a test of the affect regulation model utilising constructs that form part of the Self-Determination Theory as predictors of ED. It was hypothesised that non self-determined motivation, specifically external regulation, would b...

Long-term variability of bioassessments has not been well evaluated. We analyzed a 20-year data set (1984-2003) from four sites in two northern California streams to examine the variability of bioassessment indices (two multivariate RIVPACS-type O/E scores and one multimetric index of biotic integrity, IBI), as well as eight metrics. All sites were sampled in spring; one site was also sampled i...

INTRODUCTION This study explores predictive factors in safety culture. METHOD In 2008, a sample 939 employees was drawn from 22 departments of a telecoms firm in five regions in central Taiwan. The sample completed a questionnaire containing four scales: the employer safety leadership scale, the operations manager safety leadership scale, the safety professional safety leadership scale, and t...

Available evidence indicates that responses to conditional inferences using concrete causal premises is affected by the relative number of available alternate causes (Cummins, D.D., 1995. Memory and Cognition 23 (5), 646-658). We propose that another important factor that may influence the kinds of inferences made to causal conditionals is the relative strength of association between such cause...

This study analyzed the possibility of using movement velocity and the rate of perceived exertion as predictors of relative load in the parallel squat (PSQ) exercise. To determine the full load-velocity and load-rate of perceived exertion relationships, 290 young, resistance-trained athletes (209 males and 81 females) performed a progressive strength test up to the 1 repetition maximum. Longitu...

PURPOSE This study examined the moderating and mediating effects of self-efficacy on the relationships between predictor variables (decisional balance and processes of change) and the outcome variable (stages of change) using the Transtheoretical Model. DESIGN Cross-sectional data were collected from 147 current and former smokers at three vocational technical high schools in Korean metropoli...

INTRODUCTION According to the health-promoting approach, people should be empowered such that they take responsibility for their health and follow a healthy lifestyle. Empowerment is a process in which people confront problems and tasks in their lives in order to better control them. This study was conducted to specify the relationship between individual empowerment and health-promoting lifesty...

We take a semiparametric approach in fitting a linear transformation model to a right censored data when predictive variables are subject to measurement errors. We construct consistent estimating equations when repeated measurements of a surrogate of the unobserved true predictor are available. The proposed approach applies under minimal assumptions on the distributions of the true covariate or...

The aim of this study was to demonstrate that handgrip strength test can discriminate the presence/absence of asthma and between intermittent and moderate persistent asthma in children. 140 children (70 healthy and 70 with asthma) completed the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and performed the handgrip strength test. Forty-eight hours later, subjects performed spirometry....
