The principal aims of the study were to define different profiles of cohesion and perceived efficacy in soccer players and to measure their differences in performance. The subjects were 235 soccer players in the under-18 category who played in the National League in Spain and 15 coaches whose ages ranged from 29 to 45 years. Diverse instruments to assess cohesion, perceived efficacy, and expect...

We evaluated the efficacy of a mindful parenting program for changing parents' mindfulness, child management practices, and relationships with their early adolescent youth and tested whether changes in parents' mindfulness mediated changes in other domains. We conducted a pilot randomized trial with 65 families and tested an adapted version of the Strengthening Families Program: For Parent and ...

The effects of cutting tool coating material and cutting speed on cutting forces and surface roughness were investigated by Taguchi experimental design. Main cutting force, Fz is considered as a criterion. The effects of machining parameters were investigated using Taguchi L18 orthogonal array. Optimal cutting conditions were determined using the signal-to-noise (S/N) ratio which is calculated ...

BACKGROUND In-stent restenosis (ISR) remains a difficult problem in interventional cardiology. The relative efficacy and safety of available interventions is not clear. We aimed to perform a network meta-analysis using both direct evidence and indirect evidence to compare all available interventions. METHODS AND RESULTS We systematically searched electronic databases for randomized trials com...

This study examined the effects of creativity training on creative self-efficacy. We developed a creativity course based on social cognitive theory. The course was conducted in two formats: a five-day course and a condensed one-day course. Samples consisted of students and municipality employees (five-day course), and special education teachers (one-day course). Students from amathematics and s...
