Abstract This study introduces the type-I heavy-tailed Burr XII (TIHTBXII) distribution, a highly flexible and robust statistical model designed to address the limitations of conventional distributions in analyzing data characterized by skewness, heavy tails, and diverse hazard behaviors. We meticulously develop the TIHTBXII’s mathematical foundations, including its probability density function (PDF), cumulative distribution function (CDF), and essential statistical properties, crucial for theoretical understanding and practical application. A comprehensive Monte Carlo simulation evaluates four parameter estimation methods: maximum likelihood (MLE), maximum product spacing (MPS), least squares (LS), and weighted least squares (WLS). The simulation results consistently show… More >

Abstract This study aimed to confirm the hierarchical factor structure and the criterion validity of the Brief Mental Flexibility Questionnaire (BMFQ) in the South African context. Three hundred and eighty-five employees from a public institution in South Africa participated in the study. Confirmatory factor analysis affirmed the structural validity of the measure, comprising a general factor of mental flexibility and six distinct processes consistent with acceptance and commitment therapy (ACT): cognitive, affective, perceptual, attentional, motivational, and behavioral flexibility. Multiple regression analysis revealed differential predictive weights of these dimensions for general mental health, with cognitive flexibility as More >

Abstract Objectives: College students face increasing mental health challenges. Although Acceptance and Commitment Therapy (ACT) is effective, the efficacy of Internet-based ACT (iACT) needs further exploration. Methods: This study examines the efficacy of iACT on college students’ mental health through a randomized controlled trial. We recruited 90 college students (19.16 ± 1.02 years old) and randomly divided them into the iACT group, face-to-face ACT group, and control group. The effects of the interventions were evaluated using the comprehensive assessment of ACT processes (CompACT) and the Depression Anxiety Stress Scales (DASS-21). Results: Two-factor repeated measures ANOVA revealed a… More >

Abstract Background: Restrained eating, often motivated by the desire to control weight, is prevalent among young female college students and is considered a risk factor for eating disorders. Negative evaluation fear, exacerbated by social pressure, peer comparison, and academic stress, has been identified as a potential contributor to restrained eating behavior. However, research exploring the relationship between negative evaluation fear and restrained eating, particularly in the context of self-esteem and physical appearance perfectionism, remains limited. This study aims to investigate these relationships and design an intervention program to reduce restrained eating behaviors in female college students.… More >

Abstract Objectives: This study aimed to assess the reliability and validity of the abbreviated Committed Action Questionnaire (CAQ-8) in a cohort of 1635 Chinese university students. Methods: Participants completed the Chinese version of the CAQ-8 along with other standardized measures, including the Acceptance and Action Questionnaire-II (AAQ-II), the Valuing Questionnaire (VQ), the Satisfaction with Life Scale (SWLS), the Depression Anxiety Stress Scales (DASS-21), and the World Health Organization Five-item Well-Being Index (WHO-5). A retest was conducted one month later with 300 valid responses. Results: Exploratory factor analysis (n = 818) identified a 2-factor structure, confirmed through validated… More >

Abstract The Cross-domain Heuristic Search Challenge (CHeSC) is a competition focused on creating efficient search algorithms adaptable to diverse problem domains. Selection hyper-heuristics are a class of algorithms that dynamically choose heuristics during the search process. Numerous selection hyper-heuristics have different implementation strategies. However, comparisons between them are lacking in the literature, and previous works have not highlighted the beneficial and detrimental implementation methods of different components. The question is how to effectively employ them to produce an efficient search heuristic. Furthermore, the algorithms that competed in the inaugural CHeSC have not been collectively reviewed. This… More >

Abstract Communication could be an essential part of couples in their daily life. Based on Monitor and Acceptance Theory (MAT), the present study explored the mediating role of communication in the relationship between mindfulness and relationship quality among college-student couples. The research examined the dynamic relationship of monitoring and acceptance to relationship satisfaction in the Actor-Partner Interdependence Model (APIM), and the mediating effect of positive or negative communications in these relationships. A total of 96 pairs of couples in the universities in Nanjing, China participated in the research. Momentary measurements were used to measure the momentary More >

Abstract Objectives: This study reviewed published randomized controlled trials (RCTs) and evaluated the efficacy of internet-based acceptance and commitment therapy (IACT) on adolescent mental health. Methods: Searches were conducted in PubMed, ProQuest, APA (PsycNET/PsycINFO), and Web of Science from inception to January 2022 to identify RCTs evaluating the effects of IACT on adolescents. The included studies were assessed for quality and risk of bias. This study was performed using the standard mean difference and associated 95% confidence interval of effective measures. Review Manager 5.4 software was adopted to calculate the effect size. Results: Compared to adolescents in control… More >

Abstract To meet the needs of today’s library users, institutions are developing library mobile apps (LMAs), as their libraries are increasingly intelligent and rely on deep learning. This paper explores the influencing factors and differences in the perception of LMAs at different time points after a user has downloaded an LMA. A research model was constructed based on the technology acceptance model. A questionnaire was designed and distributed twice to LMA users with an interval of three months to collect dynamic data. The analysis was based on structural equation modeling. The empirical results show that the… More >

Abstract Acceptance sampling is used to decide either the whole lot will be accepted or rejected, based on inspection of randomly sampled items from the same lot. As an alternative to traditional sampling plans, it is possible to use Bayesian approaches using previous knowledge on process variation. This study presents a Bayesian two-sided group chain sampling plan (BTSGChSP) by using various combinations of design parameters. In BTSGChSP, inspection is based on preceding as well as succeeding lots. Poisson function is used to derive the probability of lot acceptance based on defective and non-defective products.
