Towards Examining the Link Between Green HRM Practices and Employee Green in-Role Behavior: Spiritual Leadership as a Moderator
2023
Grounding on the supplies-values fit theory, this study examines the effect of green HRM practices on an employee's in-role green behavior after the Covid-19 pandemic. Moreover, this study examined the mediating role of psychological green climate between green HRM practices and in-role green behaviour. In addition, we studied that spiritual leadership as a buffering mechanism strengthens the relation between psychological green climate and employee in-role behavior.
The paths were examined using hierarchical multiple regression and for moderation mediation, we used PROCESS Hayes (2003) to evaluate the data collected from 374 Chinese MNCs employees.
The findings indicate that green HRM practices have a positive effect on employees' in-role green behaviour. In addition, psychological green climate mediates the relation between green HRM practices and employee in-role green behavior. Spiritual leadership influences the strength of the moderated mediated path between green HRM practices and employee in-role green behavior (through a psychological green environment).
The most apparent manifestation of green HRM practices is the integration of environmental concerns into traditional HRM processes after Covid-19 pandemic, including hiring, training, evaluating performance, and distributing pay and benefits. These green-focused management initiatives are more likely to result in employees acting greenly.

Background
Internet gaming addiction (IGA) is a serious condition that can significantly impact personal and social functioning. Many studies of IGA have been conducted in adolescents and young adults, but there are limited data available in children. We investigated the time spent using internet gaming apps in children and its association with behavioral problems, sleep problems, alexithymia, and emotional regulation.
Methods
The research populations (N = 564) were categorized based on the number of hours spent using online gaming applications. The Strengths and Difficulties Questionnaire, the Children's Sleep Habits Questionnaire Abbreviated, the Children's Alexithymia Measure (CAM), and the Clinical Evaluation of Emotional Regulation–9 were used to assess all participants.
Results
Compared to other groups, children who used internet gaming applications for more than 6 h had a higher proportion of abnormal responses on the emotional symptoms and hyperactivity scales. Children who used internet gaming applications for more than 6 h had the poorest sleep quality (75%), while children who used internet gaming applications for 1–2 h had the best (36.7%). Participants who used internet gaming apps for 1–2 h had significantly lower mean total scores on the emotional regulation scale and total CAM, whereas those using internet gaming apps for more than 6 h had the highest mean scores in the CAM.
Conclusions
Excessive use of internet gaming apps during childhood may be associated with hyperactivity, peer problems, high socioeconomic level, alexithymia concerns, shorter daytime sleep duration, and a delayed morning wake-up.

Background
Non-Suicidal Self-injury is a critical public health concern among adolescents, often co-occurring with depression and associated with severe psychopathology. Despite its clinical relevance, research in Middle Eastern contexts remains limited. This study examined the methods, correlates, and mechanisms of self-injurious behaviours among Egyptian adolescents with and without major depressive disorder (MDD).
Methods
A case–control observational study recruited 110 adolescents (55 with MDD and 55 matched controls) from the Child and Adolescent Psychiatry Outpatient Clinic, Suez Canal University, Egypt. Diagnoses were established using DSM-IV-TR criteria. NSSI was assessed with the Deliberate Self-Harm Inventory (DSHI), and personality traits with the Junior Eysenck Personality Questionnaire (JEPQ). Between-group comparisons used chi-square and t-tests; associations were evaluated with Spearman’s correlations. Mediation was tested with structural equation modeling.
Results
NSSI was significantly more prevalent among adolescents with MDD (89.1%) than controls (56.4%,
p
< 0.001). The MDD group reported a greater variety of NSSI methods (mean 4.49 ± 3.98 vs. 2.11 ± 2.57,
p
< 0.001), with cutting the most common form. Recurrent NSSI and recent episodes (within 6 months and past year) were also more common in the MDD group. Neuroticism scores were significantly higher in the MDD group and showed positive correlations with the number of NSSI methods and frequency in both groups. Mediation analysis further indicated that depressive symptoms partially mediated the relationship between neuroticism and last-year NSSI frequency when adjusting for age and sex.
Conclusion
Adolescents with depression demonstrate higher rates, greater severity, and more diverse patterns of NSSI compared to healthy peers. Neuroticism emerged as a central personality factor linked to NSSI directly and indirectly through depressive symptoms. These findings underscore the importance of routine NSSI screening in clinical practice and the development of culturally sensitive interventions targeting emotional vulnerability among Egyptian youth.

Corporate governance quality
2023
Motivated by agency and stakeholder theories, this study aims to investigate the effect of corporate governance quality as measured by a single index on investment efficiency in the six Arab Gulf countries, commonly known as Gulf Cooperation Council (GCC) for the period 2015-2020. The study tries to develop a corporate governance quality model comprises 60 items under five main corporate governance elements of disclosure; responsibilities of the board; board effective composition; rights of shareholders and the role of stakeholders; and examines its effect on firms' investment efficiency in 301 non-financial firms listed in six emerging capital markets in the GCC region. The findings reveal significant evidence that good corporate governance quality as a composite index enhances investment efficiency and mitigates both over- and under-investment. However, when the subcomponents of the corporate governance quality index were regressed individually on investment inefficiency, the findings were mixed. Our findings remain consistent when we control for potential endogeneity bias. The study has theoretically contributed to the corporate governance literature on corporate governance indices and quality by proposing a corporate governance quality model that considers all stakeholders. The practical implications of the study emphasize the significance of good company governance as a driver of investment efficiency; companies are expected to manage resources effectively, and regulators can implement regulations that enhance corporate governance standards in the GCC countries using the developed corporate governance quality model.

Cross Culture Examination of Perceived Overqualification, Psychological Well-Being and Job Search: The Moderating Role of Proactive Behavior
2024
This study delves into the intricate interplay between perceived overqualification, job search behavior, psychological well-being, and proactive behavior, within two distinct and diverse work settings.
Drawing upon the Person-Job Fit theory, we investigated these dynamics in two unique samples: Sample 1 encompassed corporate sector employees in the United Arab Emirates (N=409), while Sample 2 comprised IT sector workers in Pakistan (N=337). Hayes PROCESS macro were used to examine the proposed hypotheses and AMOS (Version 28) were conducted to examine model fitness.
In Study 1, we established a positive association between perceived overqualification and job search behavior among employees in the UAE corporate sector. Notably, this relationship was mediated by psychological well-being, suggesting that the impact of perceived overqualification on job search behavior is, in part, channeled through its effects on individuals' psychological well-being. Study 2 showed that proactive behavior exhibited a moderating effect on the negative link between perceived overqualification and psychological well-being. Specifically, employees displaying higher levels of proactive behavior demonstrated a less adverse influence of perceived overqualification on psychological well-being. Importantly, this adaptive effect of proactive behavior was found to indirectly influence job search behavior.
The findings highlight the nature of perceived overqualification in the workplace and its varying impact on employee behavior and well-being across different cultural and work settings. The mediation by psychological well-being and moderation by proactive behavior in these relationships underscores the importance of individual responses to perceived job fit issues. These insights are crucial for understanding employee behavior in diverse work environments and can inform practices for managing perceived overqualification.

Introduction: There is an ongoing debate about the efficacy and postoperative outcomes of transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) inguinal hernia repair. Our aim is to assess the surgical outcomes of each technique, focusing predominantly on postoperative components to determine if establishing a policy to advocate for a single technique is warranted.Method: A literary review of randomized control trials and cohort studies to delineate recurrent concerns or points of contention was undertaken. A retrospective, comparative analysis was performed of TEP and TAPP primary inguinal hernia repairs performed by surgeons with more than five-year experience with their preferred technique over a three-year period (January 2020 to December 2022) at three separate institutions.Results: A total of 279 applicable cases were reviewed of which 38% (n=106) were performed as TEP and 62% (n=173) performed as TAPP. The demographic of the cohort was heavily skewed towards the male population as expected; however, there were no differences between each subgroup. TEP hernia repair showed a significantly improved postoperative pain score at one and 24 hours, respectively (1.67 ± 0.45, p < 0.05 and 1.97 ± 0.31, p < 0.05). No discernible difference was noted in the categories of length of hospital stay, recurrence rate, and overall patient satisfaction.Conclusion: The study showed overall improved results using the TEP inguinal hernia repair technique; however, no statistically significant results were demonstrated in the long term to advocate for changes to pre-existing surgeon preferences.

Background. Nipah belongs to the genus Henipavirus and the Paramyxoviridae family. It is an endemic most commonly found at South Asia and has first emerged in Malaysia in 1998. Bats are found to be the main reservoir for this virus, causing disease in both humans and animals. The last outbreak has occurred in May 2018 in Kerala. It is characterized by high pathogenicity and fatality rates which varies from 40% to 70% depending on the severity of the disease and on the availability of adequate healthcare facilities. Currently, there are no antiviral drugs available for NiV disease and the treatment is just supportive. Clinical presentations for this virus range from asymptomatic infection to fatal encephalitis. Objective. This study is aimed at predicting an effective epitope-based vaccine against glycoprotein G of Nipah henipavirus, using immunoinformatics approaches. Methods and Materials. Glycoprotein G of the Nipah virus sequence was retrieved from NCBI. Different prediction tools were used to analyze the epitopes, namely, BepiPred-2.0: Sequential B Cell Epitope Predictor for B cell and T cell MHC classes II and I. Then, the proposed peptides were docked using Autodock 4.0 software program. Results and Conclusions. The two peptides TVYHCSAVY and FLIDRINWI have showed a very strong binding affinity to MHC class I and MHC class II alleles. Furthermore, considering the conservancy, the affinity, and the population coverage, the peptide FLIDRINWIT is highly suitable to be utilized to formulate a new vaccine against glycoprotein G of Nipah henipavirus. An in vivo study for the proposed peptides is also highly recommended.

The impact of ecocentric leadership on organizational green innovation examining the serial mediation of green knowledge sharing and ambidexterity
2025
Drawing on social exchange theory, this study investigates the serial mediation relationship between ecocentric leadership, green knowledge sharing, green ambidexterity, and organizational green innovation. Additionally, it examines the moderating effects of technological orientation. Data were collected from 623 hotel employees working in the Guangdong-China hospitality industry. The structural model was analyzed using Mplus 8.6 to test the proposed model. The results indicate that ecocentric leadership has a positive influence on organizational green innovation. This relationship is mediated by green knowledge sharing and green ambidexterity, individually and sequentially. Furthermore, the mediated relationship between ecocentric leadership and organizational green innovation, facilitated through green knowledge sharing, is moderated by technological orientation. The findings suggest that fostering ecocentric leadership and enhancing technological orientation for the hospitality sector can significantly boost green innovation. Hospitality organizations should promote green knowledge sharing and ambidexterity to drive sustainable practices and innovations. This study contributes to how ecocentric leadership influences organizational green innovation through green knowledge sharing and ambidexterity. It highlights the importance of technological orientation as a moderating factor, providing valuable insights for hospitality industry practitioners.

Background
Type 1 diabetes (T1DM) in children is frequently associated with sleep disorders. The prevalence of these disorders varies by region attributable to variations in co-sleeping customs, nocturnal rituals, and environmental influences. This study aims to assess sleep problems and their related characteristics among children diagnosed with T1DM in the Upper Egypt region. This cross-sectional study involved 118 children with T1DM, aged 6 to 12 years. The outcomes from the Children’s Sleep Habits Questionnaire-Abbreviated (CSHQ-A) were utilized to categorize the subjects into two groups: the first group comprised individuals with sleep problems (
N
= 70), and the second group included individuals with non-sleep problems (
N
= 48). All participants were evaluated using the Socioeconomic Scale, the Clinical Evaluation of Emotional Regulation–9 (CEER-9), the Strengths and Difficulties Questionnaire, the Pediatric Quality of Life Inventory, and the Children’s Alexithymia Measure (CAM).
Results
Sleep problems were prevalent in 59.3% of participants. Children with sleep problems had elevated rates of overweight/obesity, ocular problems increased medication usage, exercise difficulties, diminished quality of life, higher mean scores on the emotional regulation scale, and greater levels of alexithymia as compared to those without sleep disorders. The prevalence of conduct and hyperactivity problems was greater in children with sleep problems compared to those without sleep problems. Regression analysis revealed that increased BMI, presence of ocular issues, higher alexithymia scores, and poor quality of life were associated with a greater likelihood of experiencing sleep problems.
Conclusions
Nearly two-thirds of children with T1DM in Upper Egypt experienced sleep problems. These issues were associated with higher BMI, ocular problems, elevated alexithymia scores, and poorer quality of life.

This study examines the impact of artificial intelligence (AI)-driven insights on sustainable Human Resource Management (HRM) performance in higher education institutions. It explores the mediating roles of HRM practices optimization and decision-making enhancement, as well as the moderating effects of organizational culture, AI adoption readiness, and ethical considerations. By incorporating innovative insights into artificial intelligence technologies, this research contributes to career and HRM literature by revealing how AI transforms workforce dynamics in academic institutions. Data was collected via a quantitative survey from 215 participants, including administrators, AI and data science experts, data analysts, human resource management professionals, institutional leaders, IT staff, and policymakers from higher education institutions in the UAE. Using non-probability quota sampling. Data analysis was conducted through descriptive statistics, t-tests, correlation analysis, and structural equation modeling (SEM) using Partial Least Squares SEM (PLS-SEM) in SmartPLS software. Findings confirm that AI-driven insights significantly enhance sustainable HRM performance. Both HRM practices optimization and decision-making enhancement mediate this relationship. While ethical considerations, organizational culture, and AI adoption readiness directly influence HRM sustainability, they do not significantly moderate AI’s impact, suggesting that individual engagement with AI technologies plays a more pivotal role than broader organizational factors. This research uniquely integrates the Resource-Based View (RBV) and Technology Acceptance Model (TAM) to examine AI adoption in HRM within higher education—an area previously underexplored. It underscores the importance of HRM optimization and decision-making in maximizing AI’s benefits. The findings offer strategic insights for higher education institutions seeking to enhance HRM sustainability through effective AI integration.
