Mom, dad, put down your phone and talk to me: how parental phubbing influences problematic internet use among adolescents.

BACKGROUND: The positive association of parental phubbing with internalising and externalising problems among adolescents has gained academic traction. To date, limited research has investigated the association of parental phubbing and adolescents' Problematic Internet Use (PIU). Furthermore, the mechanism underlying this association is largely unknown. These gaps limit our understanding of family-related issues affecting PIU among adolescents. The present study explores whether there is a relation between parental phubbing and PIU and investigates the mechanisms underlying this relation among adolescents. METHODS: The participants were 495 junior high schoolers aged 11-15 years. Participants completed questionnaires on their experiences with PIU, parental phubbing, parent-child relationships, and basic psychological needs satisfaction. RESULTS: The results showed a direct and indirect positive association between parental phubbing and PIU. Furthermore, parental phubbing indirectly influenced PIU and was mediated by the parent-child relationship and basic psychological needs satisfaction, respectively. Moreover, the parent-child relationship and basic psychological needs satisfaction were sequentially mediated. CONCLUSIONS: Our study highlights the crucial role of parents in the development of adolescent PIU and provides theoretical and practical guidelines for PIU prevention and intervention.

Linkage of calling and burnout among Chinese airline pilots: the role of psychological capital and organizational identification.

Objectives. Burnout of airline pilots has an extremely adverse impact on their physical and mental state, their work efficiency and safe operation of airlines, and is thus an important issue in occupational safety and health. Therefore, it is crucial to identify factors that may reduce burnout among airline pilots. Drawing on conservation of resources theory, the present study investigates the relationships between calling, psychological capital, organizational identification and burnout in order to understand the mechanisms underlying pilot burnout. Method. A cross-sectional survey was conducted to measure calling, psychological capital, organizational identification and burnout among a sample consisting of 242 Chinese commercial airline pilots (age: M 31.60 years, SD 6.44). Correlation analysis, mediation analysis and moderated analysis were conducted. Results. The results showed that calling has a direct and negative effect on pilot burnout, and an indirect effect on burnout through influencing psychological capital. Moreover, organizational identification was found to positively moderate the negative relationship between calling and pilot burnout. Conclusion. This study contributes to deepening theoretical research on burnout, and provides empirical evidence for effective intervention in the burnout of airline pilots, which is beneficial to reduce pilot human error and ensure flight safety. Future research directions are also discussed.

The influence of time structure on number prediction motion.

Time structure refers to the ratio of time spent moving during visible segments and occluded segments in position prediction motion (PM) tasks. Recent research has found that an equal time structure can improve performance in position prediction motion tasks. However, there is no research to explore the influence of time structure on the number PM task. In three behavioural experiments, this study explored whether an equal time structure improved number prediction motion performance, as it did in position tasks. The results demonstrated that an equal time structure could improve participant performance in the number prediction motion task (Experiment 1). However, equal time structures did not improve task performance when the numbers before the transition number were presented regularly one by one (Experiment 2). Experiment 3 showed that participants could actively take advantage of equal time information when the numbers before the transition number were presented irregularly. These findings demonstrated that when the number sequence was not presented in order, people could use the time structure heuristics to estimate completion time estimates (CTEs). People could sub-vocally count through mental number space when the number sequence was presented in order.

The influence of time structure on prediction motion in visual and auditory modalities.

Usually people can estimate the correct position of a moving object even when it temporarily moves behind an occlusion. Studies have been performed on this type of occluded motion with prediction motion (PM) tasks in the laboratory. Previous publications have emphasized that people could use mental imagery or apply an oculomotor system to estimate the arrival of a moving stimulus at the target place. Nevertheless, these two ways cannot account for the performance difference under a different set of conditions. Our study tested the role of time structure in a time-to-collision (TTC) task using visual and auditory modalities. In the visual condition, the moving red bar travelled from left to right and was invisible during the entire course but flashed at the initial and the occluded points. The auditory condition and visual condition were alike, except that the flashes in the visual condition were changed to clicks at the initial and the occluded points. The results illustrated that participants' performance was better in the equal time structure condition. The comparison between the two sense modalities demonstrated a similar tendency, which suggested there could be common cognitive processes between visual and auditory modalities when participants took advantage of temporal cues to judge TTC.

The Role of Work Engagement in the Association between Psychological Capital and Safety Citizenship Behavior in Coal Miners: A Mediation Analysis.

With the development of science and technology and the increasing importance attached by to these domains by the state and government departments in recent years, China's coal production and safety supervision level continue to increase. However, the prevalence of frequent coal mine safety accidents has not been effectively curbed. The main purpose of this study was to explore the mediating role of work engagement in the relationship between psychological capital and safety citizenship behavior among Chinese coal miners. Data for 317 coal miners were collected from five coal and energy enterprises. The Psychological Capital Questionnaire (PCQ), the Job Engagement Scale (JES), and the Safety Citizenship Behavior Scale (SCBS) were used to evaluate the coal miners' psychological capital, work engagement, and safety citizenship behavior. The causal steps approach and bootstrap Method were used in this study to assess the proposed mediation models. A correlation analysis indicated that psychological capital, work engagement, and safety citizenship behavior were significantly correlated with each other. Furthermore, the mediation analysis showed that work engagement mediated the relationship between psychological capital and safety citizenship behavior. Psychological capital does not only have a direct impact on coal miners' safety citizenship behavior, but it also has an indirect impact on coal miners' safety citizenship behavior via work engagement. Therefore, effectively enhancing an individual's psychological capital and work engagement may be a basic factor determining coal miners' safety citizenship behavior, which further promotes safety production within the enterprise.
