Profiles of dual commitment to the occupation and organization: Relations to well-being and turnover intentions

Abstract: Work-relevant commitments have important implications for employee behavior and well-being, but the connections are complicated by the fact that commitments can be characterized by different mindsets and be directed at different targets. Recent developments in person-centered analytic strategies (e.g., latent profile analysis) have helped to address these complexities, particularly as they pertain to the interactions among the mindset of affective, normative, and continuance commitment to the organization. In the present study we extend application of the person-centered approach to identify profiles of commitment to two interrelated targets—the organization and the occupation—in a sample of 1,096 Hong Kong teachers. We identified seven distinct profiles reflecting both similarities and differences in the nature of the dual commitments across targets, and demonstrated differing patterns of turnover intentions and well-being across the profiles. Implications for commitment theory, future research, and practice are discussed.

Type of screen time moderates effects on outcomes in 4013 children: evidence from the Longitudinal Study of Australian Children

Abstract: Excessive engagement with digital screens is harmful to children’s health. However, new evidence suggests that exposure at moderate levels may not be harmful and may even provide benefit. Therefore, our objective was to determine if there are curvilinear relationships between different types of screen time and a diverse set of outcomes, including health and education. We address our objective using a repeated measures design. Children (N = 4013), initially aged 10–11 were assessed every 2 years between 2010 and 2014. Children’s screen time behavior was measured using time-use diaries, and categorized into five types: social, passive, interactive, educational, or other. We used measures of children’s physical health, health-related quality of life, socio-emotional outcomes, and school achievement. The analysis plan was pre-registered. Models were adjusted for gender, socio-economic status, ethnicity, number of siblings, and housing factors. There were linear associations between total screen time and all outcomes, such that more screen time was associated with worse outcomes. However, there was variability when examined by screen time type. Passive screen time (e.g., TV) was associated with worse outcomes, educational screen time (e.g., computer for homework) was associated with positive educational outcomes and had no negative relations with other outcomes. Interactive screen time (e.g., video games) had positive associations with educational outcomes but negative associations with other outcomes. In all instances, these significant associations were small or very small, with standardised effects < 0.07. We found little evidence of curvilinear relationships. The small effects of screen time on children’s outcomes appear to be moderated by the type of screen time. Policy makers, educators, and parents should consider the type of screen time when considering the benefits and harms of use.

Influence of playing standard on the physical demands of professional rugby league

Abstract: In this paper we report on two studies that investigated the physical demands of professional rugby league match-play. Instudy one, National Rugby League (NRL) and National Youth Competition (NYC) players underwent global positioning system (GPS) analysis during competitive matches. No differences (P > 0.05) were observed between playing standards for minutes played, total distance covered, or the distances covered at low and high speeds. However, NRL players engaged in significantly more repeated high-intensity effort bouts than NYC players (13.1 ± 0.8 bouts vs. 9.7 ± 1.1 bouts). Reductions in physical performance occurred from the first to second half for both NRL and NYC players. In study two, we investigated, in the same players, the physical demands of professional rugby league match-play when players were competing in trial and regular fixture matches. The locomotor demands of trial matches were lower than fixture matches, with players covering less distance per minute of match-play, including less distance at low and high speeds. Players were also less likely to engage in repeated high-intensity effort bouts in trial matches than fixtures. These findings demonstrate that neither NYC matches nor NRL trial matches adequately reflect the intense physical demands of NRL fixture matches.

Evaluating brief motivational and self-regulatory hand hygiene interventions: a cross-over longitudinal design

Abstract: Background Frequent handwashing can prevent infections, but non-compliance to hand hygiene is pervasive. Few theory- and evidence-based interventions to improve regular handwashing are available. Therefore, two intervention modules, a motivational and a self-regulatory one, were designed and evaluated.
