The role of psychological stress in the subjective well-being of aviation ground crews: mediating effects of social support and self-esteem.

Background: This study investigated the relationship between psychological stress and subjective well-being among aviation ground crews, with a focus on the mediating roles of social support and self-esteem.

Methods: In this cross-sectional investigation, 533 ground crew members completed validated assessments, including the Stress Self-evaluation Test, the Perceived Social Support Scale, the Self-liking/Self-competence Scale-Revised, the Satisfaction with Life Scale and the Positive and Negative Affect Scale. Statistical analyses were performed via R software and Mplus.

A latent profile analysis of shift work tolerance among Chinese male sailors during a prolonged non-24-h rotating shift schedule at sea.

Shift work tolerance (SWT) refers to the ability to adapt to shift work without significant adverse consequences. The present study aimed to examine the individual differences in SWT and their predictors and outcomes. Latent profile analyses were conducted using cross-sectional data collected form 448 Chinese male sailors who experienced a prolonged (>30 d) non-24-h rotating shift schedule at sea.

Independent and joint trajectories of depression and anxiety symptoms among Chinese male sailors throughout a prolonged non-24-h rotating shift schedule at sea: a parallel-process growth mixture modeling approach.

Background: The predictive and protective effect of hardiness on mental health remains unclear among shift workers on non-24-h working schedules. The present study aimed to investigate the independent and joint trajectories of depression and anxiety symptoms and the role of hardiness during a prolonged period of non-24-h shift working schedule.

Methods: Four hundred nine Chinese male sailors (working on 18-h watchstanding schedule) were recruited and completed all 5-wave tests through online questionnaires (at Day 1, 14, 28, 42, 55, respectively) during a 55-day sailing.

Psychometric properties of the Brief Version of Pittsburgh Sleep Quality Index (B-PSQI) among Chinese male sailors on 18-hr rotating shift schedule.

Sleep problems among shift workers have emerged as a public health concern in recent years. However, few validation studies of self-reported sleep quality questionnaires were performed among shift workers. The present study aimed to examine the psychometric properties of the Brief Version of Pittsburgh Sleep Quality Index (B-PSQI) in a shift workers sample.

Psychometric properties of the 10-item Connor-Davidson Resilience Scale in Chinese military personnel.

Background: The 10-item Connor-Davidson Resilience Scale (CD-RISC-10) is a widely used assessment of resilience. However, psychometric properties of the Chinese version of CD-RISC-10 have not been well investigated in a Chinese military personnel sample.

Methods: A total of 3,129 Chinese military personnel completed the CD-RISC-10, Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS).

Can restricting while-in-bed smartphone use improve sleep quality via decreasing pre-sleep cognitive arousal among Chinese undergraduates with problematic smartphone use? Longitudinal mediation analysis using parallel process latent growth curve modeling.

Background And Aim: Problematic smartphone use (PSU) has become a global public health problem. Excessive while-in-bed smartphone use may result in poor sleep quality. The present study aimed to examine whether restricting while-in-bed smartphone use can improve sleep quality and the mediating role of pre-sleep cognitive arousal in this process.

Can limiting bedtime smartphone use improve next-day working memory among undergraduates with problematic smartphone use?

This study implemented a longitudinal self-control intervention experiment to examine whether limiting bedtime smartphone use can improve next-day working memory among individuals with problematic smartphone use (PSU). 156 Chinese undergraduates with PSU completed the 6-day experiment (3 nights for intervention condition and 2 nights for control condition). All participants were asked to complete N-back tests in the afternoon everyday during the experiment.

Development and validation of the while-in-bed-smartphone-use-induced sleep procrastination scale (WSPS) in Chinese undergraduates with/without problematic smartphone use.

Purpose: Problematic smartphone use (PSU) has become a global public health problem. Excessive while-in-bed smartphone use may result in sleep procrastination and other negative outcomes. The present study aimed to develop and validate a new scale called WSPS to assess while-in-bed-smartphone-use-induced sleep procrastination among undergraduates.

Parental attachment and emotional intelligence mediates the effect of childhood maltreatment on callous-unemotional traits among incarcerated male adolescents.

This study aimed to examine the impact of childhood maltreatment on callous-unemotional (CU) traits among incarcerated male adolescents, focusing primarily on the roles of parental attachment and emotional intelligence. A total of 454 male incarcerated adolescents from two juvenile correctional facilities, ranging in age from 14 to 18 years, completed a set of questionnaires consisting of a childhood trauma questionnaire, parent-attachment scale, emotional intelligence scale, and the Inventory of CU traits. The results revealed that childhood maltreatment, parental attachment, and emotional intelligence were all correlated with CU traits.

The commission of crime from the perspective of decision-making differences.

A criminal act can be regarded as an irrational decision-making process. Therefore, understanding differences in the criminal decision-making process would shed light on criminal behavior. We utilized dual processing theory to propose that offenders' differences in decision-making may cause them to adopt non-adaptive behaviors, such as high reference point setting, abnormal reward-punishment sensitivity, delayed discounting rate, and decision-making style.

Analysis of two naval pilots' ejection injuries: Two case reports.

Background: Recently, two naval pilots in a two-seat trainer jet were forced to eject urgently due to sudden mechanical failure during night-time training. They were both successfully rescued and sent to the hospital for emergency treatment. In this study, we investigate their ejection injuries and recovery process.

Circulating miR-27b as a Biomarker of the Development and Progression of Carotid Artery Stenosis.

Objective: A close relationship of microRNAs (miRNAs) with various human diseases has been widely reported, including cardiovascular disease. The current study attempted to examine the abnormal expression of miR-27b in asymptomatic carotid artery stenosis (ACAS), its diagnostic value and predictive value for the development of ACAS were also assessed.

Methods: Clinical serum samples were collected from both ACAS patients and healthy individuals, and levels of miR-27b in the clinical samples were detected using Real-time quantitative PCR.

Effect of Sleep Deprivation on the Working Memory-Related N2-P3 Components of the Event-Related Potential Waveform.

Working memory is very sensitive to acute sleep deprivation, and many studies focus on the brain areas or network activities of working memory after sleep deprivation. However, little is known about event-related potential (ERP)-related changes in working memory after sleep loss. The purpose of this research was to explore the effects of 36 h of total sleep deprivation (TSD) on working memory through ERPs.
