This study explored how psychology educators in South Africa can be professionally developed to embed Acceptance and Commitment Therapy(ACT)principles into their pedagogy,thereby enhancing psychological flexibility among postgraduate students.Using a Collaborative Action Research approach,seven educators and thirteen students participated in a ten-month intervention comprising four iterative cycles of training,implementation,and reflection.The thematic analysis found that ACT-informed pedagogy not only promoted student resilience,present-moment awareness(mindfulness),and values-based engagement(authenticity)but also catalysed shifts in educator identity toward more reflexive teaching.Students cultivated resilience by learning to tolerate emotional discomfort and sustain values-driven action,while developing mindfulness through present-moment awareness that fostered engagement.This process also nurtured authenticity,as students aligned their academic and professional identities with personally meaningful values,paralleled by educators’growing reflexivity and relational openness,signalling a values-informed pedagogy.These findings provide a theoretically grounded,contextually responsive model for cultivating soft skills in higher education,affirming the potential of ACT as a scalable,culturally congruent framework for professional development. 展开更多

This study aims to investigate the relationship between job satisfaction and organizational commitment among 206 employees in the Guinean mining sector.Organizational commitment is measured using the revised version of the three-component model developed by Meyer,Allen,and Smith(1993),while job satisfaction is measured using the Minnesota Satisfaction Questionnaire(short-form).A positive and significant association(r=0.46,p<0.01)is found between organizational commitment and job satisfaction,supporting the argument that highly satisfied workers are more committed to their organization.The findings also show that organizational commitment is positively and significantly associated with both extrinsic job satisfaction and intrinsic job satisfaction.Finally,the study also highlights a positive and significant association between job satisfaction and each dimension of organizational commitment,as well as a positive and significant correlation between the dimensions of job satisfaction and those of organizational commitment. 展开更多

Frontline employees often experience customer incivility,which may increase their intention to leave service organizations.Drawing on conservation of resources theory,this study examines how customer incivility affects turnover intention through perceived overqualification and career commitment,and whether coworker support moderates these relationships.Survey data were collected from 483 hotel employees in China and analyzed using reliability tests,correlation analysis,mediation,and moderated mediation procedures.The results show that customer incivility is positively related to turnover intention.Career commitment significantly mediates this relationship,and perceived overqualification and career commitment form a significant serial mediation path.However,the single mediation effect of perceived overqualification is not significant.Coworker support weakens the positive effects of customer incivility and perceived overqualification on turnover intention and strengthens the protective effect of career commitment. 展开更多

In this paper,a strength-constrained unit commitment(UC)model incorporating system strength constraints based on the weighted short-circuit ratio(WSCR)is proposed.This model facilitates the comprehensive assessment of area-wide system strength in power systems with high inverter-based resource(IBR)penetration,thereby contributing to the mitigation of weak grid issues.Unlike traditional models,this approach considers the interactions among multiple IBRs.The UC problem is initially formulated as a mixed-integer nonlinear programming(MINLP)model,reflecting WSCR and bus impedance matrix modification constraints.To enhance computational tractability,the model is transformed into a mixed-integer linear programming(MILP)form.The effectiveness of the proposed approach is validated through simulations on the IEEE 5-bus,IEEE 39-bus,and a modified Korean power system,demonstrating the ability of the proposed UC model enhancing system strength compared to the conventional methodologies. 展开更多

The quantum hybrid algorithm has recently become a very promising and speedy method for solving larger-scale optimization problems in the noisy intermediate-scale quantum(NISQ)era.The unit commitment(UC)problem is a fundamental problem in the field of power systems that aims to satisfy the power balance constraint with minimal cost.In this paper,we focus on the implementation of the UC solution using exact quantum algorithms based on the quantum neural network(QNN).This method is tested with a ten-unit system under the power balance constraint.In order to improve computing precision and reduce network complexity,we propose a knowledge-based partially connected quantum neural network(PCQNN).The results show that exact solutions can be obtained by the improved algorithm and that the depth of the quantum circuit can be reduced simultaneously. 展开更多

This study examined the relationships among workplace spirituality,mindfulness,mental well-being,and organizational commitment in professional female dancers.A total of 424 dancers from the United States participated in the survey.Structural equation modeling indicated that workplace spirituality was positively associated with both mental well-being and organizational commitment,whereas mindfulness was significantly related only to organizational commitment.Mental well-being was a significant predictor of organizational commitment and mediated the relationship between workplace spirituality and organizational commitment,but not between mindfulness and commitment.These results suggest that workplace spirituality functions as a psychological resource that enhances emotional health and strengthens organizational engagement.Thesefindings are consistent with self-determination theory,highlighting the role of value congruence and intrinsic purpose in sustaining motivation in high-performance contexts.Moreover,the studyfindings underscore the importance of fostering spiritually supportive work environments to promote psychological well-being and long-term organizational commitment. 展开更多

As power systems expand,solving the unit commitment problem(UCP)becomes increasingly challenging due to the curse of dimensionality,and traditional methods often struggle to balance computational efficiency and solution optimality.To tackle this issue,we propose a problem-structure-informed quantum approximate optimization algorithm(QAOA)framework that fully exploits the quantum advantage under extremely limited quantum resources.Specifically,we leverage the inherent topological structure of power systems to decompose large-scale UCP instances into smaller subproblems,which are solvable in parallel by limited number of qubits.This decomposition not only circumvents the current hardware limitations of quantum computing but also achieves higher performance as the graph structure of the power system becomes more sparse.Consequently,our approach can be extended to future power systems that are larger and more complex. 展开更多

This paper examines the application of the Verkle tree—an efficient data structure that leverages commitments and a novel proof technique in cryptographic solutions.Unlike traditional Merkle trees,the Verkle tree significantly reduces signature size by utilizing polynomial and vector commitments.Compact proofs also accelerate the verification process,reducing computational overhead,which makes Verkle trees particularly useful.The study proposes a new approach based on a non-positional polynomial notation(NPN)employing the Chinese Remainder Theorem(CRT).CRT enables efficient data representation and verification by decomposing data into smaller,indepen-dent components,simplifying computations,reducing overhead,and enhancing scalability.This technique facilitates parallel data processing,which is especially advantageous in cryptographic applications such as commitment and proof construction in Verkle trees,as well as in systems with constrained computational resources.Theoretical foundations of the approach,its advantages,and practical implementation aspects are explored,including resistance to potential attacks,application domains,and a comparative analysis with existing methods based on well-known parameters and characteristics.An analysis of potential attacks and vulnerabilities,including greatest common divisor(GCD)attacks,approximate multiple attacks(LLL lattice-based),brute-force search for irreducible polynomials,and the estimation of their total number,indicates that no vulnerabilities have been identified in the proposed method thus far.Furthermore,the study demonstrates that integrating CRT with Verkle trees ensures high scalability,making this approach promising for blockchain systems and other distributed systems requiring compact and efficient proofs. 展开更多

Objectives:For the younger generation(i.e.,Millennials and Generation Z),running is not only about physical health,but also about building psychological resources and multidimensional well-being,reflecting their unique culture and lifestyle.This study aims to investigate the structural relationships among exercise commitment,psychological capital(PsyCap),and flourishing in younger adults in South Korea by integrating Social Cognitive Theory(SCT)and Broaden-and-Build Theory(BBT)using a second-order partial least squares structural equation modeling(PLS-SEM).Methods:A total of 166 participants were recruited through convenience sampling via online survey.They were young South Korean adults(born 1983–2005)who run at least once a week and were recruited through two universities and running communities.The survey included validated scales measuring exercise commitment(cognitive and behavioral),PsyCap(hope,efficacy,resilience,and optimism),and flourishing(emotional,psychological,and social well-being).Data were analyzed using PLS-SEM with 5000 bootstrap resamples in SmartPLS 4.1.1.2.Subsequently,mea-surement and structural models were assessed through confirmatory composite analysis(CCA),and common method variance(CMV)was checked using Harman’s single-factor test.Results:Exercise commitment significantly predicted PsyCap(β=0.171,p<0.05)and PsyCap significantly predicted flourishing(β=0.444,p<0.001).Mediation analysis confirmed that PsyCap fully mediated the relationship between exercise commitment and flourishing(β=0.071,p<0.05).Although the indirect effect may appear numerically small,it translated to a 7.1%increase in flourishing scores—a practically meaningful effect in social science contexts where even modest changes yield real-world impact.The findings empirically support the integration of two frameworks,highlighting both motivational(SCT)and affective(BBT)pathways through which exercise fosters multidimensional well-being.Conclusions:Theoretically,this study advances understanding of how cognitive and behavioral commitment contribute to the development of psychological resources that collectively drive flourishing.Practically,the results suggest that running programs targeting younger adults should focus on fostering PsyCap—via goal setting,social support,and digital engagement—to maximize well-being outcomes.Moreover,the findings have the potential to inform mental health promotion strategies beyond the Korean context.This study has several limitations,including a skewed sample resulting from convenience sampling,the lack of comparative analysis across different age cohorts,and the use of second-order constructs that may obscure dimension-specific effects.Future research should address these limitations by employing stratified sampling,adopting comparative study designs,and conducting model comparisons between first-and second-order constructs to elucidate both overarching and dimension-specific pathways. 展开更多

BACKGROUND Acceptance and commitment therapy(ACT)is a third-generation therapy that appears to be a promising psychological intervention for psychotic disorders.While several systematic reviews and meta-analyses that address the efficacy of ACT for psychosis have been conducted,no systematic review has specifically focused on the application of ACT to the early stages of psychosis.AIM To review the state of the art regarding the feasibility and efficacy of treating early psychosis(EP)with ACT-based interventions.METHODS First,we describe the foundations of the ACT model to provide the background required to contextualize the main objective of this review.Second,we searched the PubMed and PsycINFO databases for studies published up to January 2025 and identified eight studies that met our selection criteria.The systematic review was conducted in accordance with the PRISMA guidelines and the critical appraisal checklist provided by the Joanna Briggs Institute for randomized controlled trials(RCTs).RESULTS All studies were published after 2019.Among the reviewed studies,five were RCTs with a total combined sample of 399 nonoverlapping participants.The methodological quality was moderate for RCTs.The results showed that ACTbased treatments are feasible and improve psychotic symptoms,medication adherence,and global functioning in patients with EP.Furthermore,preliminary evidence exists for the benefits of group-based and online-delivered programs and those that combine face-to-face therapy with novel real-time digital interventions,such as“ecological momentary intervention”,to apply therapeutic con cepts to real life.CONCLUSION ACT-based treatments in the early stages of psychosis are feasible and improve symptoms,treatment adherence,and self-care skills.Although promising,these results are inconclusive.Further research is required. 展开更多

This paper presents a new method based on an immune-tabu hybrid algorithm to solve the thermal unit commitment （TUC） problem in power plant optimization. The mathematical model of the TUC problem is established by analyzing the generating units in modem power plants. A novel immune-tabu hybrid algorithm is proposed to solve this complex problem. In the algorithm, the objective function of the TUC problem is considered as an antigen and the solutions are considered as antibodies, which are determined by the affinity computation. The code length of an antibody is shortened by encoding the continuous operating time, and the optimum searching speed is improved. Each feasible individual in the immune algorithm （IA） is used as the initial solution of the tabu search （TS） algorithm after certain generations of IA iteration. As examples, the proposed method has been applied to several thermal unit systems for a period of 24 h. The computation results demonstrate the good global optimum searching performance of the proposed immune-tabu hybrid algorithm. The presented algorithm can also be used to solve other optimization problems in fields such as the chemical industry and the power industry. 展开更多
