Predicting Mediation Role of Person-Environment Fit on Contextual Performance: Study in Indonesian Correctional Organization

ABSTRACT This study examined the mediating role of person – environment fit in the relationships of perceived organizational support and proactive personality on contextual performance. A total of 171 officers in correctional facilities in Nusakambangan Island returned usable questionnaires. Data were analyzed using SmartPLS 4. Results showed that person – environment fit partially mediated the influence of perceived organizational support and proactive personality on contextual performance. This study contributes to the existing literature by investigating and predicting the mediating role of person – environment fit which was little highlighted by previous research. The study is expected to provide insight, evidence, and knowledge for academics, HR managers, and correctional policymakers that improving officer contextual performance, improving organizational support, and attracting and retaining officers with proactive personalities can increase opportunities for organizations to build strong human resources and in turn contribute to contextual performance that can improve the achievement of organizational effectiveness.

How do customers react to the integration of AI in customer experience

Artificial Intelligence is revolutionizing customer service through enhanced customization and efficiency. Processing natural language makes interactions more human-like and guarantees higher levels of customer satisfaction. With the help of AI-enabled Chatbots communication with users occurs instantaneously, answering their questions and providing immediate responses. By forecasting preferences and suggesting recommendations through the evaluation of data collected on customers, artificial intelligence improves service quality. The amalgamation of modern technology and customer service provides a smooth, personalised and linear client experience. While AI-driven chatbots and tools prove time and cost-effective, occasional delays or failures instil human hesitation. The escalating trend of integrating AI in customer service significantly enhances the overall human experience, according to various studies. However, this study aims to address a dearth of empirical research on AI-enabled customer experiences. The absence of emotional intelligence in current AI models contributes to lacklustre customer commitment and engagement. This study investigates how customers react to Artificial intelligence being integrated into the customer service industry. The study scrutinizes pivotal factors—Perceived trustworthiness, personalization, perceived ease of use, perceived usefulness, accuracy, and quality of information provided—examining their interdependence in augmenting the customer experience. This study will utilise a proposed model which utilises the stimulus, organism, and response model. Results underscore how these factors contribute to improving customer loyalty through the mediation role of customer engagement. Hence, the study reveals the interconnectedness of these factors with brand affinity and loyalty, emphasizing the importance of these factors in fostering lasting customer relationships.

Association of glymphatic system dysfunction with cognitive impairment in temporal lobe epilepsy

ObjectivesTo explore the relationship between glymphatic dysfunction and cognitive impairment in unilateral temporal lobe epilepsy (TLE).MethodsThis study retrospectively included 38 patients with unilateral TLE and 26 age- and gender-matched healthy controls (HCs). The diffusion tensor image analysis along the perivascular space (DTI-ALPS) index, choroid plexus volume (CPV), and cognitive assessment were obtained for each participant. Neuropsychological test batteries included Montreal Cognitive Assessment (MoCA), Minimum Mental State Examination, Arithmetic Test (AT), Digit Symbol Substitution Test (DSST), Digit Span Test (DST), Boston Naming Test, Block design, Phonological Fluency Test (PFT), and Semantic Verbal Fluency (SVF).ResultsCompared to HCs, TLE patients had lower scores of MoCA, AT, DSST, DST, Block design, PFT and SVF (all p < 0.05) and lower values of mean DTI-ALPS index (1.491 ± 0.142 vs. 1.642 ± 0.123, p < 0.001). Significantly lower DTI-ALPS index values were observed in the ipsilateral hemisphere than in the contralateral hemisphere (1.466 ± 0.129 vs. 1.517 ± 0.175, p = 0.013) for patients with unilateral TLE. Correlation analyses found that SVF performance was significantly or borderline significantly associated with glymphatic function (FDR-corrected p < 0.05 for all DTI-ALPS index and FDR-corrected p = 0.057 for CPV) in TLE patients. Linear regression analyses showed that increased CPV and decreased DTI-ALPS index were independent risk factors for semantic fluency impairment (all p < 0.05). Furthermore, mediation analyses found the mediator role of the mean DTI-ALPS index in the relationship between choroid plexus enlargement and semantic fluency impairment (indirect effect: β = −0.182, 95%CI = −0.486 to −0.037).ConclusionThese findings reveal the important role of the DTI-ALPS index and CPV in SVF performance in unilateral TLE. Decreased DTI-ALPS index and increased CPV are the independent risk factors for semantic fluency impairment. The DTI-ALPS index may fully mediate the relationship between CP enlargement and SVF performance. These insights provide a radiological foundation for further investigations into the mechanism of the glymphatic system in TLE pathophysiology.

Self-compassion improves barrier self-efficacy and subsequently physical activity: A test of longitudinal mediation using a representative sample of the United Kingdom.

Self-compassion, which directs the awareness of suffering, sympathetic concerns and caring motives towards oneself, is an important psychological quality and resource for health and well-being. In the context of physical activity, self-compassion can help individuals overcome obstacles, recuperate from a setback or a lapse and engage in regular physical activity. The present research was the first to examine the longitudinal effects of self-compassion on physical activity and the mediation role of barrier self-efficacy of such effects. We recruited a national representative sample of 654 UK adults and followed them over three timepoints across 9 months. At each time point, participants completed an online survey assessing levels of state self-compassion, barrier self-efficacy and physical activity behaviours. We examined the longitudinal effects of self-compassion on physical activity and the mediation role of barrier self-efficacy. Baseline state self-compassion consistently correlated with physical activity levels at Times 2 and 3. Barrier self-efficacy at Time 2 mediated the longitudinal effect of baseline state self-compassion on Time 3 physical activity, after controlling for within- (e.g., Time 1 on Time 2 self-compassion) and between-person variations (e.g., covariance of self-compassion and physical activity within a timepoint). Adopting a self-compassionate mind facilitates engagement and maintenance of physical activity. Future studies could consider accelerometer-based physical activity measures and develop and validate a more context-specific state self-compassion measure tailored for physical activity contexts. Researchers and practitioners should consider incorporating self-compassion to future interventions and education programmes for promoting physical activity.

Modelling tourists’ travel intention: Role of tourism destination image, perceived value and situational involvement

Promoting travelling intention within social media is significant for stakeholders to grasp a new tourism market and cultivate a new model for development of tourism industry. This study aims to understand path of destination image affecting travelling intention, and to investigate the mediation role of perceived value, furthermore, to uncover the role of moderator of situational involvement. This paper conducts a survey on tourists visiting Guilin, collecting 435 questionnaires, and uses the structural equation modeling method to explore how the image of the tourism destination affects tourists’ willingness to travel. The research results indicate that cognitive image, emotional image, and projected image all have a significant positive impact on perceived value, perceived value as a significant mediator to bridge the relationship among the destination image and tourists’ travel intention. Furthermore, situational involvement plays a negative moderating role in the mediating effect of emotional value. This study endeavor will serve to enrich the understanding of perceived value theory, destination image theory, and tourism consumer behavior theory. It will also provide theoretical foundations and policy recommendations for guiding tourism consumer behavior, analyzing destination image perception, and destination marketing.

Personality Traits and Quality of Life Among Older Adults: The Chain Mediating Effects of Perceived Social Support and Positive Coping Styles

The pathways between personality traits and older adults’ quality of life (QOL) have been well studied. However, perceived social support and positive coping styles should not be ignored by older adults’ QOL. Hence, this study examines the chain mediating role of perceived social support and positive coping styles between personality traits and older adults’ QOL. In total, 230 older individuals (Mean age = 69.43, SD age = 7.23, age range from 60 to 93) participated in this study. All older people provided a rating of QOL and perceived social support, the Chinese Big Five personality, and positive coping styles. (1a) the five personality traits of older adults were significantly associated with QOL; (2b) perceived social support mediated the relationship between three personality traits (neuroticism, extraversion, and agreeableness) and QOL; (3c) positive coping styles played a mediator role in the personality traits (neuroticism, extraversion, and agreeableness) and QOL; (4d) perceived social support and positive coping styles had a significant chain mediating effect on the three dimensions of personality traits (neuroticism, extraversion, and agreeableness) and QOL. As mediating influences, social support and positive coping styles can be applied to efforts to promote QOL for older adults who share the personality traits of neuroticism, extraversion, and agreeableness.

Navigating the New Normal: Psychological Capital's Mediating Role in the Work-From-Home Paradigm

Working from home (WFH) has become the expected trend as a result of the COVID-19 epidemic. The impact of family conflict, social isolation, distracting environment, job autonomy, and self-leadership on employees' productivity, work engagement, and stress levels have been examined in this study with a mediating role of Psychological capital. There has been little study on the impact of Psychological capital as a mediator and its influence on remote work productivity, work engagement, and stress. The data was collected from employees of IT sector organizations. Through online and print surveys, a sample of 429 respondents was gathered using the convenience sampling method. The dependent variables were workers’ productivity, work engagement, and Stress, the mediating variable was Psychological Capital and the independent variables were family-work conflict, social isolation, distracting environment, job autonomy, and self-leadership under the framework of the Job Demand and Resource model. The PLS-SEM tool was used to investigate the association between research variables. The SPSS tool was used to run the descriptive statistics of respondents. Through this study, it was able to conclude that Job Demand and Job Resources significantly impact productivity, work engagement, and stress through psychological capital. Job Demand negatively impacts productivity, and work engagement and positively impacts stress while Job Resource positively impacts productivity, and work engagement and negatively impact stress.

The Effect of Urinary Polycyclic Aromatic Hydrocarbon Metabolites on Lipid Profiles: Does Oxidative Stress Play a Crucial Mediation Role?

Urinary polycyclic aromatic hydrocarbon (PAH) metabolites are associated with oxidative stress; however, epidemiological studies have not reported the impacts of these urinary PAH metabolites on blood lipid levels. This study investigated the relationship between urinary PAH metabolites, urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), and blood lipid profiles. A total of 109 elderly volunteers were recruited with complete datasets for analysis. Blood and morning urine samples were collected in the winter of 2011. The PAH metabolites, creatinine, and 8-OHdG levels in urine samples were analyzed using Gas Chromatography-Mass Spectrometry, spectrophotometry, and an ELISA kit, respectively. The blood lipid profiles were analyzed using an automatic biochemical analyzer. The relationship between lipid profiles and 8-OHdG was assessed using a two-independent sample nonparametric test, categorized by gender, smoking, and alcohol consumption status. After normalizing the concentration values, a general linear regression model was employed to examine the correlations between PAH metabolites, 8-OHdG, and lipid profiles. A mediation model was developed to investigate the mediating effect of 8-OHdG on the relationship between PAH metabolites and lipid profiles. The median of eight PAH metabolite concentrations in urine samples ranged from 1 to 10 μmol/mol creatinine (Cr). Significant differences in lipid profiles were observed across genders. However, no significant differences were found in smoking or alcohol consumption status for both genders. Linear regression analysis revealed that an increase in the logarithmic concentration of 2-hydroxynaphthalene (2-OHNap), 9-hydroxyfluorene (9-OHFlu), 3-hydroxyfluorene (3-OHFlu), 2-hydroxyfluorene (2-OHFlu), 1-hydroxypyrene (1-OHPyr), and 6-hydroxychrysene (6-OHChr) was associated with an increase in urinary 8-OHdG levels, after adjusting for BMI and age. Specifically, 1-hydroxynaphthalene (1-OHNap) and 1-OHPyr correlated negatively with apolipoprotein A1 (Apo A1). Conversely, 1-OHPyr was positively correlated with low-density lipoprotein cholesterol (LDL-C). In addition, b,c-dihydroxyphenanthrene (2-OHBcPhe) was positively associated with apolipoprotein B (Apo B). Notably, 8-OHdG did not exhibit a significant correlation with lipid profiles. The mediating effect of 8-OHdG on the relationship between hydroxylated PAHs and lipid profiles was not statistically significant. However, the indirect effects of hydroxylated PAHs on blood lipids were statistically substantial, specifically for 1-OHNap to Apo A1 (-0.025, 95% CI: -0.041, -0.009), 1-OHPyr to LDL-C (0.107, 95% CI: 0.011, 0.203), and 2-OHBcPhe to Apo B (0.070, 95% CI: 0.005, 0.135). This study suggests that an increase in urinary PAH metabolites may elevate the levels of urinary 8-OHdG and influence blood lipid profiles. However, no direct relationship was found between 8-OHdG and lipid profiles. The mediation analysis indicated that the effects of PAH metabolites on lipid changes may operate through pathways other than oxidative stress.

Lean logistics and corporate green practices: messianic methodologies for achieving business excellence in the logistics industry via green stakeholder satisfaction

PurposeThis study aims to explore how logistics firms exploit lean logistics and corporate green practices as significant catalysts for achieving business excellence via the mediation roles of green internal stakeholder satisfaction and green external stakeholder satisfaction.Design/methodology/approachQuestionnaire is used in garnering data from 137 Ghanaian logistics firms. Structural equation modeling, particularly partial least squares, was applied to test all hypotheses.FindingsThe results confirm the notion that although lean logistics has positive effect on business performance, the effect is insignificant; hence, it is the concurrent implementation of lean logistics and corporate green practices that leads to superior business performance. The mediation analysis further confirms that both green internal stakeholder satisfaction and green external stakeholder satisfaction are significant precursors through which logistics firms can achieve superior business performance when lean logistics and corporate green practices can influence business performance.Research limitations/implicationsData is collected from logistics firms from a single country. Hence, the results obtained cannot be imported to reflect the general occurrence in other geographical settings.Practical implicationsThis study informs managers of logistics firms that lean and green strategies are compatible when implemented together; hence, it should not be treated in isolation. Managers are further enlightened that in their pursuit of business excellence, there is a need to prioritize green internal stakeholder satisfaction and green external stakeholder satisfaction via prudent investment in lean and green practices.Originality/valueThe research model proposed in this study magnifies the literature on lean and environmental management via bridging the literature gap concerning the interrelationship between lean logistics, corporate green practices, green internal stakeholder satisfaction, green external stakeholder satisfaction and business performance.

THE MEDIATING ROLE OF EMOTIONAL SATISFACTION AND PATIENT TRUST IN THE RELATIONSHIP BETWEEN SERVICE QUALITY AND REVISIT INTENTION

Revisit intention is an interesting issue in the field of marketing and is important in the service industry because maintaining customer loyalty in the long term is the success key of a business. Measuring and predicting revisit intention is considered as one of the important indicators of the achievement of service companies. This study aims to investigate the effects of service quality on the revisit intention of patients to hospitals, as well as the mediating role of emotional satisfaction and patient trust on the relationship between service quality and revisit intention. The sample used in this study amounted to 200 respondents who were patients with non BPJS Health insurance who visited at least three times in 2021-2023. The sampling technique in this study used non probability sampling technique (purposive sampling). The method used in this study is Structural Equation Modeling (SEM) and using smart PLS 3.2.9 software. The findings of this study shows that service quality does not have a direct impact on revisit intention of non-BPJS Health patients, but rather an indirect impact through emotional satisfaction and patient trust. Emotional satisfaction mediates the relationship between service quality and revisit intention, while patient trust also plays a role. Based on the analysis of mediation influence, emotional satisfaction and patient trust play a role in full mediation (indirect-only).

The Mediator Role of Psychological Ownership in the Effect of Perceived Managerial Support on Individual Work Performance: A Research in the Health Care Sector

The study aimed to determine the mediator role of psychological ownership in the relationship between nurses' perceived managerial support and individual work performance. The descriptive and cross-sectional study sample included Osmaniye provincial and district hospital nurses. A mixed analysis, including both quantitative (n=414) and qualitative (n=23) analysis methods, was used for the study. While the quantitative data were tested using the Structural Equation Model (SEM), content analysis was used to analyse the qualitative data. According to the findings, it was concluded that psychological ownership partially mediated the effect of perceived managerial support on individual work performance.

Impact of metals exposure on lung function and serum club cell secretory protein among schoolchildren: A mixture and mediation analysis

Particulate matter (PM) and its harmful components are significant contributors to respiratory diseases and impaired lung function, especially in children. Club cell secretory protein (CC16) is a maker of lung epithelium or club cell injuries. To date, the relationship between metals related with PM and CC16 and lung function impairment has been overlooked in children. We enrolled 603 schoolchildren exposed to different levels of PM in China. We found per doubling increase, urinary thallium, and iron was associated with a 3.42 % (95 % CI: 0.01, 6.72) and 3.09 % (95 % CI: 0.55, 5.56) decrease of serum CC16, respectively, whereas urinary cadmium was associated with a 4.74 % (95 % CI: 1.29, 8.31) increase of serum CC16. The Bayesian kernel machine regression (BKMR) model confirmed these associations and showed a potential synergistic interaction between thallium and cadmium. Urinary metal mixtures were associated with lower CC16 when they were below the 35th percentile compared with their median. Serum CC16 mediated 11.47 % (95 % CI: 0.06, 45.00) of the association between urinary thallium and FEV1/FVC decline. The inverted U-shaped association with CC16 and the mediation role of CC16 on associations with lung function provide insight into the mechanisms underlying lung injury induced by metals related with PM.

Sustainable Growth of Learner Engagement and Well‐Being Through Social (Teacher and Peer) Support: The Mediator Role of Self‐Efficacy

ABSTRACTThe facilitation of learners' achievement may be enhanced by considering the role of different constructs of positive psychology (PP) such as well‐being and engagement. Besides, there is a widespread belief that self‐efficacy has become an important psychological construct that can affect learners' academic performance. Additionally, the interpersonal connections that learners have with their teachers and peers within the educational setting play a pivotal role in their intellectual development. Several studies have confirmed that both peers and teachers have a significant role in shaping the academic performance of learners. Nevertheless, there is a dearth of empirical research examining the potential relationship between peer and teacher support and its impact on learner engagement (LE), and well‐being with the mediator role of self‐efficacy. Therefore, this research was designed to examine it among 640 students in China. The package of five questionnaires, namely the teacher and peer support, LE, well‐being, and self‐efficacy was administered to collect the data. The results obtained from the structural equation model (SEM) indicated that students who receive higher levels of support from their educators and classmates were engaged more and had high well‐being. Moreover, regression analysis indicated that social (teacher and peer) support was a predictor of both well‐being (β = 0.436, p < 0.01) and engagement (β = 0.666, p < 0.01). Furthermore, social (teacher and peer) support was a strong predictor of efficacy (β = 0.768, p < 0.01). Indeed, self‐efficacy could predict both well‐being (β = 0.446, p < 0.01) and engagement (β = 0.183, p < 0.01). As a result, some suggestions are recommended for teachers, students, teacher educators and other members of the academic community.

The Mediation Role of Coping With Stress in the Relationship Between Psychological Flexibility and Posttraumatic Growth in Cancer Patients.

Objectives: Active and adaptive coping strategies have been identified as factors that can assist cancer patients in effectively managing and overcoming the crisis, leading to the potential for post-traumatic growth during the diagnosis and treatment stages. Psychological flexibility is another factor that can protect individuals and promote more adaptive reactions to traumatic situations. The study aims to examine the investigation of the mediation role of coping with stress in the relationship between psychological flexibility and posttraumatic growth in cancer patients. Methods: This study was conducted with 97 (63 women, 34 male) participants aged between 38 and 82 who are literate and diagnosed with breast cancer or gynecological cancers (endometrial, cervical, vulvar) undergoing radiotherapy planning at the Radiation Oncology Clinic of Zonguldak Bülent Ecevit University Hospital. Demographic Information Form, Psychological Flexibility Scale, Post-Traumatic Growth Inventory, and Coping Styles Scale were applied to the participants. The mediation effects were interpreted using bootstrap confidence intervals and VAF values. Results: This study showed that the active coping styles partially mediated the relationship between psychological flexibility and posttraumatic growth. Conclusion: In this regard, by organizing psychoeducational programs and interventions aimed at increasing psychological flexibility for individuals diagnosed with cancer or undergoing treatment, individuals can be enabled to cope with stress more actively, and thus post-traumatic growth can be achieved.

Parental attachment and mental health in Chinese early adolescents: The mediation role of narcissism

The generalization of multiple attachment models in Chinese youth is still unknown, and the specific effect of combined parental attachment on the mental health of early Chinese adolescents and the mechanism behind it remains unclear. Therefore, the aim of this study was to empirically investigate the effect of parental attachment on early Chinese adolescents’ mental health, to examine which multiple attachment model could best explain this impact, and to explore the mediating effect of narcissism between them. A sample of 834 early adolescents was recruited to complete standard questionnaires. Regression analyses, MANOVA, and mediation analysis were performed. We found (1) the effects of parental attachment on the mental health of early Chinese adolescents were generally consistent with the integrative model of multiple attachment; (2) a linear relationship was observed between combined parental attachment and anxiety/depression, while a curvilinear relationship was observed between combined parental attachment and life satisfaction; (3) combined parental attachment could affect mental health through vulnerable narcissism instead of grandiose narcissism. The current study offered one of the first evidence for the association between parental attachments and early adolescents’ mental health within a multiple attachment framework in China and provided valuable insight into the role of narcissism between them, as well as contributing to the literature by suggesting that the integrative model could be better refined by considering the characteristics of the indicators.

Segregation in 1 Kings 12:1-24 as a warning against the culture of religion and ethnicity in Nigeria

This paper examines the account of segregation in 1 Kings 12:1-24, where the Kingdom of Israel divides into two distinct entities due to political, religious, and ethnic tensions. By analysing this biblical narrative, the study highlights the destructive consequences of division based on cultural and religious differences. The paper draws parallels to the contemporary context of Nigeria, a nation marked by diverse ethnic and religious identities. It argues that the story serves as a cautionary tale for Nigeria, emphasizing the dangers of allowing cultural and religious differences to foster division and conflict. This is a qualitative study using the narrative method. Data was gotten from secondary literature and analysed using content analysis. The impacts of the culture of religion and ethnicity reveal that it affects electoral politics, governance and representation, conflict and instability, social cohesion, education and socialisation, and economic inequality. Emerged themes include: a) leadership and consultation; b) economic disparities and grievances; c) responses to grievances; d) secessionist movements; and e) role of mediation and reconciliation. Recommendations are discussed.
