The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations

How social/environmental determinants and inflammation affect salivary telomere length among middle-older adults in the health and retirement study

Social epidemiology posits that chronic stress from social determinants will lead to a prolonged inflammatory response that may induce accelerated aging as measured, for example, through telomere length (TL). In this paper, we hypothesize variables across demographic, health-related, and contextual/environmental domains influence the body’s stress response, increase inflammation (as measured through high-sensitivity C-reactive protein (hs-CRP)), and thereby lead to shortening of telomeres. This population-based research uses data from the 2008 Health and Retirement Study on participants ages ≤ 54–95 + years, estimating logistic regression and Cox proportional hazards models of variables (with and without confounders) across the domains on shortened TL. A mediation analysis is also conducted. Contrary to expectations, hs-CRP is not associated with risk of shortened TL. Rather, factors related to accessing health care, underlying conditions of frailty, and social inequality appear to predict risk of shorter TL, and models demonstrate considerable confounding. Further, hs-CRP is not a mediator for TL. Therefore, the social determinants of health examined do not appear to follow an inflammatory pathway for shortened TL. The finding of a relationship to social determinants affecting access to health care and medical conditions underscores the need to address social determinants alongside primary care when examining health inequities.

How Positive and Negative Emotions Promote Ritualistic Consumption Through Different Mechanisms

Ritualistic consumption refers to integrating ritual elements into the process of product design and usage. By conducting three studies, we find that ritualistic consumption can offer new and interesting experiences and help consumers gain a sense of control. Both positive and negative emotions can promote ritualistic consumption tendencies. However, their underlying psychological mechanisms are different. Specifically, positive emotion can arouse consumers’ desire for interesting experience and thus promotes their preference for ritualistic consumption, while negative emotion can arouse consumers’ need for control and thus promote their preference for ritualistic consumption. Our research results offer a theoretical contribution and practical inspiration for emotional marketing.

Humble Leadership and Team Innovation: The Mediating Role of Team Reflexivity and the Moderating Role of Expertise Diversity in Teams

The current study proposes a moderated mediation model to explain the relationship between humble leadership and team innovation. Our hypothesis integrates social information processing (SIP) theory with the existing literature on humble leadership. As a result, we theorize that when a humble individual leads a team, the team members are more likely to reconsider strategies, review events with self-awareness, share diverse information, and adapt to new ideas, which in turn promotes innovative team activities. Moreover, consistent with the research that emphasizes the inclusion of team culture in exploring leader-innovation relationships, we investigate the moderating role of a team's expertise diversity in the above positive, indirect relationship. We test our model by using both archival and survey data collected from 135 teams within 18 medium-to-large internet technology firms in China. The findings largely support our theoretical assertions, suggesting that humble leadership has important implications for team processes and innovation.

Work Stressors and Occupational Health of Young Employees: The Moderating Role of Work Adaptability

Work adaptability refers to the work experience, habits, and skills that enable an individual to adapt to current or changing work tasks and situations. It is a coping resource that individuals use to mitigate various types of stress. Adopting the interaction model of work stress, this study investigated 168 young employees in 20 organizations in Zhejiang Province through interview research and a questionnaire survey. The results show that work adaptability has a significant main effect on occupational health. The work adaptability of employees plays a moderating role in the relationship between occupational health and lack of work meaning stress, role conflict stress, interpersonal relationship stress, negative organizational atmosphere stress, and total score of work stressors. Young employees with high work adaptability have worse occupational health under high-level stress situations due to a lack of work meaning. For promoting occupational health in young employees, organizations should have this group of workers complete meaningful jobs or inform them of the importance of their jobs, reduce role conflict, and create a supportive organizational atmosphere. For management, it is imperative to eliminate high-level stress that stems from a lack of work meaning in order to retain young employees with high work adaptability. These findings shed light on how work adaptability helps young employees deal with stress and improve their occupational health. In organizational and self-stress management, it is beneficial to improve employees’ work adaptability continuously as a means of effectively resisting stress and maintaining occupational health.

Apology and Its Acceptance: Perceived Reconciliatory Attitudes Reduce Outgroup Dehumanization

Based on real-life intergroup animosities originating from a historical conflict, the current study examined how the perceived stance of the outgroup about the conflict affects the dehumanization of the outgroup. In Study 1 (N = 120), Korean undergraduates attributed more human nature to the Japanese after reading an article that the Japanese government did (vs. refused to) issue an official apology for a historical wrong. In turn, the more human nature assigned to the Japanese predicted higher expectations about positive mutual relations in the future. Similarly, in Study 2 (N = 209), Japanese undergraduates attributed more human uniqueness to Koreans after reading an article that an official apology for a historical wrong from Japan was accepted (vs. rejected) by Koreans. The higher the perceived human uniqueness of Koreans was, the higher were the willingness to help and the expectations of a positive relationship in the future. The findings demonstrate how mutual dehumanization can be reduced as a result of the other side’s reconciliatory stances and can further contribute to improving intergroup relations.

The Effect of FGF23 on Cardiac Hypertrophy Is Not Mediated by Systemic Renin-Angiotensin- Aldosterone System in Hemodialysis

Fibroblast growth factor 23 (FGF23) is elevated in patients with chronic kidney disease and contributes to left ventricular hypertrophy (LVH). The aim of the analysis was to determine whether this effect is mediated by the renin-angiotensin-aldosterone system (RAAS) in hemodialysis. Serum samples from 62 randomized hemodialysis patients with LVH were analyzed for plasma renin activity (PRA-S), angiotensin II (AngII), and metabolites, angiotensin-converting enzyme-2 (ACE2) and aldosterone using a high throughput mass spectrometry assay. Compared to healthy individuals, levels of the RAAS parameters PRA-S, AngII and aldosterone were generally lower [median (IQR) PRA-S 130 (46–269) vs. 196 (98, 238) pmol/L; AngII 70 (28–157) vs. 137 (76, 201) pmol/L; Aldosterone 130 (54, 278) vs. 196 (98, 238) pmol/L]. We did not find an indication that the effect of FGF23 on LVH was mediated by RAAS parameters, with all estimated indirect effects virtually zero. Furthermore, FGF23 was not associated with RAAS parameter levels throughout the study. While there was a clear association between FGF23 levels and left ventricular mass index (LVMI) at the end of the study and in the FGF23 fold change and LVMI change analysis, no association between RAAS and LVMI was observed. Serum concentrations of PRA-S, AngII, and aldosterone were below the ranges measured in healthy controls suggesting that RAAS is not systemically activated in hemodialysis patients. The effect of FGF23 on LVMI was not mediated by systemic RAAS activity. These findings challenge the current paradigm of LVH progression and treatment with RAAS blockers in dialysis.

Exploring the association between birthweight and breast cancer using summary statistics from a perspective of genetic correlation, mediation, and causality

BACKGROUND

Previous studies demonstrated a positive relationship between birthweight and breast cancer; however, inconsistent, sometimes even controversial, observations also emerged, and the nature of such relationship remains unknown.

METHODS

Using summary statistics of birthweight and breast cancer, we assessed the fetal/maternal-specific genetic correlation between them via LDSC and prioritized fetal/maternal-specific pleiotropic genes through MAIUP. Relying on summary statistics we conducted Mendelian randomization (MR) to evaluate the fetal/maternal-specific origin of causal relationship between birthweight, age of menarche, age at menopause and breast cancer.

RESULTS

With summary statistics we identified a positive genetic correlation between fetal-specific birthweight and breast cancer (r_g = 0.123 and P = 0.013) as well as a negative but insignificant correlation between maternal-specific birthweight and breast cancer (r_g = - 0.068, P = 0.206); and detected 84 pleiotropic genes shared by fetal-specific birthweight and breast cancer, 49 shared by maternal-specific birthweight and breast cancer. We also revealed fetal-specific birthweight indirectly influenced breast cancer risk in adulthood via the path of age of menarche or age at menopause in terms of MR-based mediation analysis.

CONCLUSION

This study reveals that shared genetic foundation and causal mediation commonly drive the connection between the two traits, and that fetal/maternal-specific birthweight plays substantially distinct roles in such relationship. However, our work offers little supportive evidence for the fetal origins hypothesis of breast cancer originating in utero.

Design thinking traits and cognitive passive resistance: mediating effect of linear thinking

Purpose

The purpose of this study is to theoretically link design thinking with behavioural strategy, using empirical results that relate three cognitive dimensions: design thinking personality traits, cognitive passive resistance and linear thinking, and, consequently, determine: if there is a negative relationship between design thinking traits and cognitive passive resistance and if this relationship is mediated by linear thinking.

Design/methodology/approach

This study used a quantitative methodology of covariance-based structural equation modelling. The data were collected from a three-scale, self-completed questionnaire, which was constructed using the existing modelling of the academic literature. The questionnaire was validated by confirmatory factor analysis and applied to a sample of 342 professional engineering and business graduates in Colombia.

Findings

The results of the structural equation modelling demonstrate a negative relationship between design thinking traits and cognitive passive resistance, and this relationship is mediated by linear thinking. These findings link design thinking and behavioural strategy and build new foundations for future studies, providing further theoretical support to the academic literature’s discussion of the relationship between design thinking and theories of managerial practices and innovation management.

Research limitations/implications

The main limitation of this study is the subjectivity of the answers because of potential bias from the respondents in completing the questionnaire. Another limitation is that the research was conducted only in the context of Colombia, so it is recommended that other studies be carried to generalise the results. This study has several theoretical implications. This study contributes to existing research on design thinking, evidencing a promising field of study to support it theoretically, such as the behavioural strategy. This study also contributes to the literature on innovation management deepening into a field of study that has received less attention in the literature, such as passive cognitive resistance to innovation. Likewise, this study presents a theoretical contribution to the dual process of cognition, proposing a new dimension to the construction of the multidimensional concept of nonlinear thinking. This study also contributes to the behavioural strategy field, evidencing a growing area of application in strategic management, such as design thinking. Finally, this research also proposes the development of a new research avenue about the concept of knowledge hiding as a possible source of innovation resistance.

Practical implications

This research also has implications for business and engineering education and practice. This study’s results suggest that before implementing an organisational initiative such as design thinking, which seeks to change people's behaviour, it is necessary to approach it as a cognitive process and develop strategies to mitigate passive cognitive resistance to change. This research’s results also present implications for business and engineering education, evidencing the need to include other perspectives of thinking that allow non-designers to develop creative thinking.

Originality/value

To the best of the authors’ knowledge, this is the first quantitative study on design thinking as a business management concept using linear thinking of non-designers to relate design thinking traits with cognitive passive resistance. This research provides theoretical and empirical support for framing design thinking within the field of behavioural strategy.

Influential factors for COVID-19 related distancing in daily life: a distinct focus on ego-gram

BACKGROUND

The coronavirus disease 2019 (COVID-19) has necessitated that individuals comply with personal quarantine rules in daily life. South Korea is implementing the concept of "distancing in daily life" to raise awareness on personal quarantine measures, which is communicated through various media channels and platforms. The continued rise in COVID-19 cases demands that all individuals strictly adhere to personal quarantine rules. It is worth paying particular attention to the college student group, which has the highest percentage of confirmed cases among all age groups in South Korea. This group understands and practices "distancing in daily life" but with drastic variations among individuals. Previous studies have reported that the level of adherence to social norms is different according to each ego stated, and media exposure level is reported as a major influencing factor. Therefore, this study examined the media exposure level to COVID-19 prevention rules and its effect on the observance of distancing in daily life; it also verified the moderating effect of ego-gram on the relationship between media exposure level and distancing in daily life.

METHODS

The participants comprised Korean university students (men = 143, women = 188, N = 331) aged 18-30 years, who were recruited through an online survey. The survey was conducted over 20 days from January 27 to February 15, 2021. Data were analyzed using SAS (version 9.4) to calculate hierarchical regression.

RESULTS

First, media exposure level and distancing in daily life among Korean university students was above average. Second, media exposure level (β = .161, P < .01) was identified as the most influential factor for distancing in daily life. Third, ego-grams had a moderating effect (β = .136, P < .05) on the relationship between media exposure levels and distancing in daily life.

CONCLUSIONS

This study examined the policy implications related to the development of diverse quarantine-related programs while considering influential factors and differences in how individuals' compliance with quarantine rules were presented. Considering the situation in which new infectious diseases such as COVID-19 occur every 4-5 years, this study serves as a preparation for future pandemics and is an important framework to enhance the level of personal quarantine.

Personality Traits, Technology-Related Teaching Skills, and Coping Mechanisms as Antecedents of Teachers' Job-Related Affective Well-Being and Burnout in Compulsory and Higher Education Online Teaching Settings

Teachers’ job-related well-being has been affected by the sudden shift to emergency remote online teaching due to the COVID-19 pandemic which has totally reshaped the task performance. Therefore, this study attempts to enlighten the possible reasons for the deterioration in teachers’ job-related well-being and proposes an integrated application of three models of prediction for job-related affective well-being and burnout as teachers’ indicators for the well-being in online teaching settings. The first model includes personality traits (extroversion, neuroticism, and conscientiousness) measured with the revised neuroticism, extroversion, and openness personality inventory (NEO-PI-R). The second model integrates an indispensable skill for the online teaching which is technological pedagogical content knowledge (TPCK) as technology-related teaching skill conceptualized by the TPACK framework. The TPACK model is a technology integration that identifies three types of knowledge instructors need to combine for successful EdTech integration - technological, pedagogical, and content knowledge (i.e., TPACK). The third model, a multidimensional one, includes coping mechanisms (e.g., problem-focused coping, emotion-focused coping, social support coping, and avoidant coping) as mediators in the relationship between personality traits and TPCK on the one side, and job-related well-being indicators on the other side. Findings from regression analyses were used to test the first two models, and the findings from a mediation analysis were used to test the third model to show that teachers’ TPCK explains a significant amount of variance in the job-related affective well-being of the teachers. The analyses also demonstrate that avoidant coping particularly mediates the relation between burnout and job-related affective well-being during COVID-19 school closures. Results indicate the efficacy of the TPACK model in increasing the job-related well-being of the teachers. The analysis of the data led to recommend that teachers should improve their personal technology-related teaching skills and adopt coping strategies in consistent with their personality traits. Moreover, public schools, as organizations, could advance educational technology programs to enhance technology-related teaching skills with the aim of increasing the well-being of their employees in online teaching settings.

Electronic health record implementation and healthcare workers' work characteristics and autonomous motivation-a before-and-after study

Background

Technological innovation in healthcare is often assumed to contribute to the quality of care. However, the question how technology implementation impacts healthcare workers has received little empirical attention. This study investigates the consequences of Electronic Health Record (EHR) implementation for healthcare workers’ autonomous work motivation. These effects are further hypothesized to be mediated by changes in perceived work characteristics (job autonomy and interdependence). Additionally, a moderating effect of profession on the relationship between EHR implementation and work characteristics is explored.

Methods

A quantitative uncontrolled before-and-after study was performed among employees from a large university medical centre in the Netherlands. Data were analysed following the component approach for testing a first stage moderated mediation model, using Generalized Estimating Equations (GEE).

Results

A total of 456 healthcare workers (75 physicians, 154 nurses, 145 allied healthcare professionals, and 82 administrative workers) finished both the baseline and the follow-up survey. After EHR implementation, perceived job autonomy decreased, whereas interdependence increased. In line with our hypothesis, job autonomy was positively associated with autonomous motivation. In contrast to our expectations, interdependence also showed a positive association with autonomous motivation. Autonomous motivation was stable over the course of EHR implementation. This study did not provide support for a moderating effect of profession: no differences were observed between the various professions regarding the changes in their experienced job autonomy and interdependence after EHR implementation.

Conclusions

Our study showed that healthcare professionals’ perceptions of their work characteristics, but not their autonomous motivation, were changed after EHR implementation, and that these experiences were relatively similar for physicians, nurses, and allied healthcare professionals. The stability of healthcare workers’ autonomous motivation may be explained by the opposite effects of decreased job autonomy and increased interdependence, and by the EHR being in line with healthcare workers’ values. The changes in job autonomy and interdependence may have consequences beyond motivation, for example by affecting clinical decision-making, proactive behaviour, and the quality of teamwork. These potential consequences of EHR implementation warrant further research.

Aberrant Salience and Disorganized Symptoms as Mediators of Psychosis

Introduction

Ideas of reference (IR) are frequent in psychopathology, mainly in psychotic disorders. The frequency of IR and preoccupation about them are related to the psychotic dimension, and to a lesser extent, to negative or emotional disorganized dimensions. Aberrant salience (AS), has been proposed as an indicator of the onset of psychosis, particularly of schizophrenia. This study analyzed the mediating role of AS, disorganized symptoms and preoccupation about IR in the relationship between IR and the psychotic dimension.

Method

The sample consisted of 330 participants (116 university students and 214 clinically active patients), 62.4% of whom were women aged 18-79. The Referential Thinking Scale, the Aberrant Salience Inventory, and the Brief Psychiatric Rating Scale were administered.

Results

Evidence of a partial mediation model showed that the relationships between IR and the psychotic dimension were mediated jointly by AS and the disorganized dimension, and preoccupation about IR no longer had a role. This relationship was significantly influenced by participant age. The variables in the model explained 54.16% of the variance.

Conclusion

The model proposed enabled a set of vulnerabilities (unusual thought content) to be predicted that could lead to a high-risk general pathological state and proneness to psychosis in particular. These findings are discussed with regard to early detection and prevention of psychosis.

The Presence of a Visual Dividing Line Increases Consumer Memory Through Attention Grabbing

Marketers often use a visual line to divide the product information on an advertisement into left-right (or top-bottom) segments for aesthetic or categorization purposes. The present research examined the effect of the dividing line on the consumer memory. Across three studies (including an eye-tracking study and a field one), we showed that the presence of a dividing line enhances consumers’ memory about the products displayed on the left/top of an advertisement. This effect occurs because the dividing line orients participants’ first eye fixation to the left/top area of the advertisement, such that their visual attention is largely restricted to that area and they could better remember the contents displayed on that area. The theoretical contributions and implications for marketers and consumers are discussed.

Psychological, social and technical factors influencing electronic medical records systems adoption by United States physicians: a systematic model

BACKGROUND

Wide adoption of electronic medical records (EMR) systems in the United States can lead to better-quality medical care at lower cost. Despite the laws and financial subsidies by the United States government for service providers and suppliers, interoperability still lags. An understanding of the drivers of EMR adoption for physicians and the role of policy-making can translate into increased adoption and enhanced information sharing between medical care providers.

METHODS

Physicians across the United States were surveyed to gather primary data on their psychological, social and technical perceptions towards EMR systems. This quantitative study builds on the theory of planned behaviour, the technology acceptance model and the diffusion of innovation theory to propose, test and validate an innovation adoption model for the healthcare industry. A total of 382 responses were collected, and data were analysed via linear regression to uncover the effects of 12 variables on the intention to adopt EMR systems.

RESULTS

Regression model testing uncovered that government policy-making or mandates and other social factors have little or negligible effect on physicians' intention to adopt an innovation. Rather, physicians are directly driven by their attitudes and ability to control, and indirectly motivated by their knowledge of the innovation, the financial ability to acquire the system, the holistic benefits to their industry and the relative advancement of the system compared to others.

CONCLUSIONS

Identifying physicians' needs regarding EMR systems and providing programmes that meet them can increase the potential for reaching the goal of nationwide interoperable medical records. Government, healthcare associations and EMR system vendors can benefit from our findings by working towards increasing physicians' knowledge of the proposed innovation, socializing how medical care providers and the overall industry can benefit from EMR system adoption, and solving for the financial burden of system implementation and sustainment.

Empathy and Anxiety in Young Girls with Fragile X Syndrome

We tested whether empathy is impaired and associated with anxiety in girls with fragile X syndrome (FXS). We measured parent-reported empathy and self-reported anxiety in young girls with FXS and in a developmentally-matched comparison group. Girls with FXS received higher parent-reported scores on cognitive and affective empathy but also self-reported more severe anxiety symptoms, particularly separation anxiety and phobia symptoms, than girls in the comparison group. Girls with FXS who received higher cognitive empathy scores, however, appeared buffered against risk for separation anxiety and phobia symptoms. Girls with FXS experience elevated empathy and anxiety relative to their developmentally-matched peers. Higher cognitive empathy in girls with FXS may indicate resilience against specific forms of anxiety that are commonly observed in FXS.

The Influence of Self-Serving Leadership on Deviant Behaviors in the Workplace: A Moderated Mediation Model

Self-serving leadership is a typical example of destructive leadership that has negative effects on its subordinates and organization. According to social identity theory, we propose a theoretical model that self-serving leadership induces employee interpersonal deviance and organizational deviance through organization identification, and we explore the moderating role of moral identity in this relationship. Based on survey data collected from 377 questionnaires by using a three-wave time lagged design, structural equation modeling results showed that (1) there was a significant positive correlation between self-serving leadership and employees’ deviant behavior, (2) organizational identification partially mediates the relationship between self-serving leadership and employees’ deviant behavior, and (3) employees’ moral identity negatively moderates the relationship between self-serving leadership and employees’ organizational identification. The findings further extend the research on the influence of self-serving leadership on employee workplace deviance. They also reveal the mechanisms and boundary conditions of the effect of self-serving leadership on employee workplace deviance.

The angiopoietin-like protein 4, apolipoprotein C3, and lipoprotein lipase axis is disrupted in patients with rheumatoid arthritis

Background

Modulators of triglyceride metabolism include lipoprotein lipase (LPL), angiopoietin-like protein 4 (ANGPTL4), and apolipoprotein C-3 (ApoC3). There is evidence on the influence of this triangle of molecules on an increased risk of atherosclerotic cardiovascular disease (CV) in the general population. Patients with rheumatoid arthritis (RA) present changes in lipid profiles and accelerated CV disease. In the present study, we set out to study whether the ANGPTL4, ApoC3, and LPL axis differs in subjects with RA compared to controls. In a further step, we investigated the relationship of this axis with subclinical atherosclerosis in patients with RA.

Methods

Cross-sectional study that included 569 individuals, 323 patients with RA and 246 age-matched controls. ANGPTL4, ApoC3 and LPL, and standard lipid profiles were analyzed in patients and controls. Carotid intima-media thickness (cIMT) and carotid plaques were assessed in RA patients. A multivariable analysis was performed to assess whether the ANGPTL4, ApoC3, and LPL axis was altered in RA and to study its relationship with RA dyslipidemia and subclinical carotid atherosclerosis.

Results

Most lipid profile molecules did not differ between patients and controls. Despite this, and after fully multivariable analysis including CV risk factors, use of statins, and changes in the lipid profile caused by the disease itself, patients with RA showed higher serum levels of ANGPTL4 (beta coef. 295 [95% CI 213–376] ng/ml, p<0.001) and ApoC3 (beta coef. 2.9 [95% CI 1.7–4.0] mg/dl, p<0.001), but lower circulating LPL (beta coef. −174 [95% CI −213 to −135] ng/ml, p<0.001). ANGPTL4 serum levels were positively and independently associated with a higher cIMT in patients with RA after fully multivariable adjustment.

Conclusion

The axis consisting in ANGPTL4, ApoC3, and LPL is disrupted in patients with RA. ANGPTL4 serum levels are positively and independently associated with a higher cIMT in RA patients.

Fostering Hotel-Employee Creativity Through Micro-Level Corporate Social Responsibility: A Social Identity Theory Perspective

Due to globalization, a dynamic business environment, and stiff rivalry, the importance of employee creativity (EC) has increased in the current era more than ever before. The hotel sector has no exception, rather the need for creativity is high in this sector because most hotels operate in ways that are easy to imitate. Recently, researchers have paid attention to micro-level corporate social responsibility (ML-CSR) and have linked it to achieve different employee-related outcomes such as EC. However, the above relationship was less explored in a hospitality context. To bridge this gap, the current analysis aims to investigate the relationship of ML-CSR and EC with the mediating effect of work engagement (WE) in the hotel sector of a developing country. The study also attempts to extend the boundary of social identity theory in a collectivistic culture to explain the link between ML-CSR and EC. The data were collected from hotel employees (n = 461) and were analyzed with the help of structural equation modeling. The findings validated that ML-CSR positively influenced EC, and WE mediated this relationship. The current work offers different contributions to the theory and the field which are discussed in detail.

A Comparative Analysis of the Effects of Objective and Self-Assessed Financial Literacy on Stock Investment Return

Till now, comprehensive and quantitatively meaningful analyses of stock market participation outcomes of retail investors have been limited by data sources in developing countries. This article devised a special questionnaire related to stock investment to measure the financial literacy (FL) and stock investment return (SIR) for the subjects with stockownership in China and to theoretically and empirically study the effects of objective FL, self-assessed FL, and their composite FL on SIR. The results of the comparative analysis showed that self-assessed FL has a greater effect on SIR than objective FL, and the effect is mediated by risk preference. In addition, we found that competent and overconfident respondents have higher SIR, while under confident respondents cannot gain from the stock market. We also found that risk preference has a positive mediating effect in the relationship between competence and overconfidence and SIR, and a negative mediating effect in the relationship between under confidence and SIR. We thus concluded that confident investors can gain more stockholding returns via taking more risks regardless of the level of their actual financial knowledge. Our findings would be a meaningful complement to the studies of stock market participation.

Genetically Determined Lifestyle and Cardiometabolic Risk Factors Mediate the Association of Genetically Predicted Age at Menarche With Genetic Predisposition to Myocardial Infarction: A Two-Step, Two-Sample Mendelian Randomization Study

Background

Observational studies have shown an association between early age at menarche (AAM) and myocardial infarction (MI) with recorded cases. In this Mendelian randomization (MR) study, we used large amounts of summary data from genome-wide association studies (GWASs) to further estimate the association of genetically predicted AAM with genetically predicated risk of MI and investigate to what extent this association is mediated by genetically determined lifestyles, cardiometabolic factors, and estrogen exposure.

Methods

A two-step, two-sample MR study was performed by mediation analysis. Genetic variants identified by GWAS meta-analysis of reproductive genetics consortium (n = 182,416) were selected for genetically predicted AAM. Genetic variants identified by the Coronary ARtery DIsease Genome-wide Replication and Meta-analysis plus The Coronary Artery Disease Genetics Consortium (n = 184,305) were selected for genetically predicted risk of MI. Genetic variants from other international GWAS summary data were selected for genetically determined mediators.

Results

This MR study showed that increase in genetically predicted AAM was associated with lower risk of genetically predicted MI (odds ratio 0.91, 95% confidence interval 0.84–0.98). Inverse variance weighted (IVW) MR analysis also showed that decrease in genetically predicted AAM was associated with higher genetically predicted alcohol intake frequency, current smoking behavior, higher waist-to-hip ratio, and higher levels of systolic blood pressure (SBP), fasting blood glucose, hemoglobin A1c (HbA1c), and triglycerides (TGs). Furthermore, increase in genetically predicted AAM was associated with genetically predicted longer sleep duration, higher levels of high-density lipoproteins, and older age at which hormone replacement therapy was started. The most essential mediators identified were genetically predicted current smoking behavior and levels of HbA1c, SBP, and TGs, which were estimated to genetically mediate 13.9, 12.2, 10.5, and 9.2%, respectively, with a combined mediation proportion of 37.5% in the association of genetically predicted AAM with genetically predicted increased risk of MI in an MR framework.

Conclusion

Our MR analysis showed that increase in genetically predicted AAM was associated with lower genetically predicted risk of MI, which was substantially mediated by genetically determined current smoking behavior and levels of HbA1c, SBP, and TGs. Intervening on the above mediators may reduce the risk of MI.

Transcriptome-wide analyses of adipose tissue in outbred rats reveal genetic regulatory mechanisms relevant for human obesity

Transcriptomic analysis in metabolically active tissues allows a systems genetics approach to identify causal genes and networks involved in metabolic disease. Outbred heterogeneous stock (HS) rats are used for genetic mapping of complex traits, but to-date, a systems genetics analysis of metabolic tissues has not been done. We investigated whether adiposity-associated genes and gene co-expression networks in outbred heterogeneous stock (HS) rats overlap those found in humans. We analyzed RNAseq data from adipose tissue of 415 male HS rats, correlated these transcripts with body weight (BW) and compared transcriptome signatures to two human cohorts: the "African American Genetics of Metabolism and Expression" and "Metabolic Syndrome in Men". We used weighted gene co-expression network analysis to identify adiposity-associated gene networks and mediation analysis to identify genes under genetic control whose expression drives adiposity. We identified 554 orthologous "consensus genes" whose expression correlates with BW in the rat and with body mass index (BMI) in both human cohorts. Consensus genes fell within eight co-expressed networks and were enriched for genes involved in immune system function, cell growth, extracellular matrix organization and lipid metabolic processes. We identified 19 consensus genes for which genetic variation may influence BW via their expression, including those involved in lipolysis (e.g., Hcar1), inflammation (e.g., Rgs1), adipogenesis (e.g., Tmem120b) or no previously known role in obesity (e.g., St14, Msa4a6). Strong concordance between HS rat and human BW/BMI associated transcripts demonstrates translational utility of the rat model, while identification of novel genes expands our knowledge of the genetics underlying obesity.

Sleep Satisfaction May Modify the Association between Metabolic Syndrome and BMI, Respectively, and Occupational Stress in Japanese Office Workers

The association between obesity and psychological stress is ambiguous. The aim is to investigate the association between metabolic syndrome (MetS) and body mass index (BMI), respectively, with occupational stress among Japanese office workers. The study is a secondary analysis of the intervention group from a randomized controlled trial. There are 167 participants included in the analysis. Occupational stress is self-reported using the Brief Job Stress Questionnaire (BJSQ). BMI and the classification of MetS/pre-MetS was based on the participants’ annual health check-up data. The primary exposure is divided into three groups: no MetS, pre-MetS, and MetS in accordance with Japanese guidelines. The secondary exposure, BMI, remains as a continuous variable. Multiple linear regression is implemented. Sensitivity analyses are stratified by sleep satisfaction. Pre-MetS is significantly associated with occupational stress (7.84 points; 95% CI: 0.17, 15.51). Among participants with low sleep satisfaction, pre-MetS (14.09 points; 95% CI: 1.71, 26.48), MetS (14.72 points; 95% CI: 0.93, 28.51), and BMI (2.54 points; 95% CI: 0.05, 4.99) are all significantly associated with occupational stress. No significant associations are observed in participants with high sleep satisfaction. The findings of this study indicate that sleep satisfaction may modify the association between MetS and BMI, respectively, and occupational stress.

Chained multimediator model of sexual orientation disclosure, sexual minority stigma, sexual minority identity, social support, and resilience among ymsms

Introduction

This study aimed to investigate sexual orientation disclosure and mental health among young men who have sex with men (YMSMs). To this end, we constructed a chained multimediator model of sexual minority stigma, sexual minority identity, social support, and resilience, with the moderator of sexual orientation disclosure.

Methods

We conducted a cross-sectional survey of 345 YMSMs in Nanning, China. Bivariate analysis was used to evaluate factors associated with sexual orientation disclosure. Sexual minority stigma was used to predict identity, with social support as the step 1 mediator and resilience as the step 2 mediator. Sexual minority identity was analyzed using a chained moderated mediation model; sexual orientation disclosure was included as a moderator in all models to control its confounding effect.

Results

The average age of YMSMs was 20.0 ± 1.3 years. Bivariate analysis indicated that YMSMs who disclosed sexual orientation may have experienced less stigma (15.49 ± 3.02 vs 16.21 ± 2.74), obtained more social support (65.98 ± 11.18 vs 63.19 ± 11.13), had strong psychological resilience (37.40 ± 8.57 vs 35.39 ± 7.73), and had a more positive self-identity (104.12 ± 21.10 vs 95.35 ± 16.67); differences between subgroups were statistically significant (p < 0.05). Sexual minority stigma, perceived stigma, and enacted stigma were significantly associated with social support and resilience. The association between sexual minority stigma and sexual minority identity was significantly mediated by social support (indirect effect [95% CI] =  − 3.307 [− 4.782, − 1.907]). Resilience significantly mediated the same association for identity (− 2.544 [− 4.052, − 1.114]). The chained relationship from sexual minority stigma to social support, resilience, and identity was also significant, with an indirect effect of − 0.404 [− 0.621, − 0.249].

Conclusion

Among YMSMs in China, sexual minority stigma affects sexual minority identity through social support and resilience. Given the psychological effects of stigma, social support and resilience must be considered to better promote positive self-identity and mental health among YMSMs.

Internal Migration and Depression Among Junior High School Students in China: A Comparison Between Migrant and Left-Behind Children

Using data from the China Education Panel Survey (CEPS), which was a nationally representative sample of junior high school students, this study examined the association of internal migration with depression among migrant and left-behind children, while exploring the moderating effect of gender difference and the mediating effects of social relationships. The results showed that migrant children had a significantly lower level of depression than left-behind children. Further, the difference in mental health between migrant children and left-behind children was more prominent for boys than girls. The mechanism analyses indicated that compared to left-behind children, internal migration positively predicted parent–child relationships and peer relationships of migrant children, which in turn reduced their depressive symptoms. Although migrant children suffered from a higher level of teacher discrimination than their left-behind counterparts, it had no significant relationship with depression after controlling for children’s social relationships with parents and peers. Our findings suggested that migrating with parents was helpful to reduce children’s depressive symptoms in comparison with being left behind. Therefore, actions should be implemented to reduce the occurrence of involuntary parent–child separation and the prevalence of children’s depressive disorders due to institutional constraints. In addition, necessary treatments are needed to improve the psychological wellbeing of disadvantaged children, especially among left-behind children with mental illness.

The Multilevel Study on the Impact of High-Performance Human Resource Practices on Employees' Voice Behavior: A Moderated Mediation Model

Based on the social identity theory, the relationship and influencing mechanism between high-performance human resource practices (HPHRPs) and employees’ voice behavior were explored by constructing a moderated mediation model, and the relationship between the field of human resources and the field of organizational behavior was also established. Through 1,178 paired samples of supervisor-employee survey and multilevel linear model analysis technology, it was found that (1) HPHRPs had a positive impact on employees’ voice behavior; (2) perceived insider status played a mediating role between HPHRPs and voice behavior; (3) voice efficacy played a moderating role between perceived insider status and voice behavior; and (4) voice efficacy played a mediating role in the relationship between “HPHRPs-perceived insider status-voice behavior.”

Exploring the Impact and Path of Environmental Protection Tax on Different Air Pollutant Emissions

Existing studies have examined the double dividend effect of environmental protection tax. However, less attention has been paid to the influencing factors and transmission paths of the pollution abatement effect of the environmental protection tax. Based on the panel data for 30 of China’s provinces from 2007 to 2019, this study discusses the environmental protection tax’s influencing factors and transmission paths on the emission scale and intensity of different air pollutants through the panel threshold regression model and mediating effect model. The results show that: (1) the environmental protection tax has a positive emission reduction effect on the emission scale or emission intensity of sulfur dioxide (SO₂) and nitrogen oxides (NO₂); (2) the abatement effect is stronger when per capita gross regional product is above the threshold value; (3) technological progress, economic growth, and industrial structure all have positive mediating effects. Therefore, the local environmental protection tax rate should be set with comprehensive consideration of regional economic development, industrial structure, and technological progress.

Maternal and child social support and food availability in relation to child growth in four low- and middle-income countries

Previous studies showed positive associations between specific types of social capital and child nutritional status. Our study examined whether improved food availability mediates the impact of maternal and child social support on child nutritional status in four low- and middle-income countries. We used data from the Young Lives cohort study, comprising 1,000 children aged 8 and 12 in Vietnam and Ethiopia, 1008 in India, and 714 in Peru. The outcome variables were the z-scores for height for age and body mass index (HAZ and BAZ, respectively). The causal mediation analysis framework was used. In Peru, above-median values of maternal social support and receiving child financial support were positively associated with HAZ at age 12. The level of maternal financial support was positively associated with BAZ among 12-year-old children in India. Peru was the only country where a positive association was found between food availability and maternal financial support among children aged 12. However, food availability did not mediate the effect of maternal financial support on HAZ at age 12. Strengthening social support to improve child nutritional status, especially by improving food availability, may not be a sufficient intervention in resource-poor settings because sources of support may lack sufficient food resources to share. However, more comprehensive measurements of social support and food security are necessary to better understand the mechanism of social support and child nutritional status.

How Does Inequality Affect the Residents' Subjective Well-Being: Inequality of Opportunity and Inequality of Effort

Based on the Chinese General Social Survey database (2010-2015), this article explores the relationship between income inequality and residents' subjective well-being from the perspective of inequality of opportunity and inequality of effort. We find that inequality of opportunity has a negative impact on subjective well-being in China, where inequality of effort has a positive impact. Our empirical results are robust for changing the inequality indicators. In the sub-sample studies, consistent conclusions are obtained in rural areas, whereas in urban areas only inequality of effort has a significant impact. The results of mechanism study show that inequality of opportunity decreases residents' sense of fairness, and inequality of effort increases residents' sense of fairness, thus affecting their subjective well-being. The results of this study provide a good response to the inconclusive research findings on the impact of income inequality on subjective well-being.

Optimism and survival: health behaviors as a mediator-a ten-year follow-up study of Chinese elderly people

Background

Optimism—the generalized expectation that good things will happen—is a promising health asset. Mounting evidence indicates that there are specific associations between optimism and survival rates. However, for public health purposes, it is critical to consider whether the relationship between optimism and survival holds for older adults as a whole and to explore the role of health behaviors as potential mediators.

Methods

Prospective data were obtained from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Optimism was measured in 2008, and survival was measured by survival time of the interviewees during the whole observation period from 2008 to 2018. Cox proportional hazard models were employed to evaluate the association between optimism and survival among the elderly. The mediating effect analysis method was used to explore the potential mediating role of health behaviors on the association between optimism and survival.

Results

Compared to less optimistic older adults, optimistic individuals were associated with lower odds of mortality (HR = 0.94, 95% CI = 0.89 − 0.99). Health behaviors are key elements that play a positive role in survival (HR = 0.95, 95% CI = 0.94 − 0.96). Health behaviors played an intermediary role in the relationship between optimism and mortality, and the mediating effect was -0.005.

Conclusions

Optimism and health behaviors were broadly and robustly associated with a lower risk of mortality. Health behaviors mediate the relationship between optimism and mortality. Appropriate intervention should be carried out on optimism and health behaviors among elderly people to improve the likelihood of health in aging.

Organizational Justice and Employee Readiness for Change: The Mediating Role of Perceived Organizational Support

Recent studies have shown that an organization must adapt to change to succeed in a constantly changing market. However, most change efforts fail due to employee resistance to change. It is critical to address employee readiness for change to avoid employee resistance. Employees’ perceptions of fair treatment by their organizations have positively predicted their Readiness for organizational change. This research aims to investigate the influence of organizational justice on employee readiness for change using perceived organizational support (POS) as a mediator. This study was carried out on the Ethiopian Revenue and Customs Authority (ERCA) and conducted with 359 employees. The study used a structural equation model and multiple regression analysis to analyze the data. The model developed explains how POS mediates the positive relationship between organizational justice and employee readiness for change. The result shows that organizational justice is a significant influencing factor on employee readiness for change. Furthermore, POS mediates the positive influence of organizational justice on employee readiness for change. This study can assist public and private organizations, as well as policymakers and practitioners, in improving and encouraging different organizational change practices in Ethiopia. Moreover, this study can also contribute to the literature on organizational change by filling the gaps in the relationship between organizational justice and employees’ Readiness for organizational change. Overall, this study concludes that organizations in Ethiopia, including ERCA, should investigate the influence of organizational justice on employee readiness for change to have successful organizational change.

A Cross-Sectional Study of Individual Learning Passion in Medical Education: Understanding Self-Development in Positive Psychology

Background

Boosting the individual learning passion of medical students is a novel approach to improve their academic performance. It facilitates the medical education reform, motivating both policymakers and educators to focus on the function of positive psychology in the career development of medical students. Therefore, this study aimed (1) to assess the status of two types of learning passion; (2) to clarify the relationship between self-esteem and two types of learning passion among Chinese medical students; (3) to examine the mediating role of psychological capital (PsyCap) in the relationship between self-esteem and two types of learning passion, respectively; and (4) to identify the moderating role of professional identity in the relationship between PsyCap and two types of learning passion, respectively.

Methods

A cross-sectional online survey was conducted from April to June 2016 in China. A total of 1,218 valid questionnaires (effective completion rate: 67.93%) were collected from four medical schools.

Results

Self-esteem significantly and positively influenced medical students’ PsyCap (β = 0.637, P < 0.01) and two types of learning passion, including harmonious learning passion (β = 0.589, P < 0.01) and obsessive learning passion (β = 0.436, P < 0.01). PsyCap fully mediated the relationship (β = 0.578, P < 0.01) between self-esteem and harmonious learning passion positively, whereas it suppressed the relationship (β = 0.490, P < 0.01) between self-esteem and obsessive learning passion. Further, professional identity significantly moderated the correlation between PsyCap and harmonious learning passion (β = −0.554, P < 0.05), rather than obsessive learning passion (P > 0.05).

Conclusion

Two types of learning passion of medical students are positively influenced by self-esteem and PsyCap. Medical students with high-level self-esteem should possess strong PsyCap, which augments their harmonious as well as obsessive learning passion. Moreover, the positive effect of medical students’ PsyCap on harmonious learning passion is more notable among those with a lower professional identity. Finally, this study argues that strengths-based interventions of self-esteem and PsyCap are a beneficial approach for future enhancing learning passion in the domain of medical education.

Perceived usefulness of technology and multiple salient outcomes: the improbable case of oil and gas workers

This research aimed at assessing the effect perceived usefulness of technology on multiple salient outcomes in Nigeria. Specifically determining how employee performance affects the perceived usefulness of technology in the oil and gas sector. The study used a descriptive research design. The target population of the study was 495 employees of selected oil and gas firms in Nigeria who have been recognized to have adopted strategies to communicate the usefulness of adopted technology in their business operations. This study used the purposive sampling technique to collect data from the employees of the selected firm. The questionnaire was used as the main data collection instrument, on a population of 495 and a total of 460 was collected back for the study analysis. A descriptive research design was adopted to establish trends related to the objectives of this study. Specifically, this research used a quantitative method (questionnaire) for the collection of data while structural equation modeling was used to analyze the data collected. The result showed that the perceived usefulness of technology has a significant effect on salient outcomes on workers in the oil and gas. Hence, the result shows that the perceived usefulness of technology contributes more to employees' satisfaction, organizational support, and employees' productivity while employees' commitment had the least. This study recommended that organizations in the oil and gas industry have to increase their efforts using strategies to improve the use of adopted technologies to promote employees’ commitment. However, organizations are to maintain strategies of perceived usefulness of technology on organizational support.

Two-level moderated mediation models with single-level data and new measures of effect sizes

This article proposes a two-level moderated mediation (2moME) model with single level data, and develops measures to quantify the moderated mediation (moME) effect sizes for both the conventional moME model and the 2moME model. A Bayesian approach is developed to estimate and test moME effects and the corresponding effect sizes (ES). Monte Carlo results indicate that (1) the 2moME model yields more accurate estimates of the parameters than the conventional moME model; (2) the 95% credibility interval following the 2moME model covers the moME effects and the ESs more accurately than that following the conventional moME model; and (3) statistical tests for the existence of the moME effects with the 2moME model are more reliable in controlling type I errors than those with the conventional moME model, especially under heteroscedasticity conditions. In addition, the developed measures of ES are more interpretable, and directly answer the questions regarding the extent to which a moderator can account for the change of the mediation effect between the predictor and the outcome variable through the mediator variable. An empirical example illustrates the application of the 2moME model and the ES measures.

The association between social media addiction and eating disturbances is mediated by muscle dysmorphia-related symptoms: a cross-sectional study in a sample of young adults

PURPOSE

Although the association between problematic use of the internet and eating disorders (EDs) in young adults has been previously established, its underlying mechanisms have not been completely clarified. It has been suggested that exposure to idealized very thin and toned body images (e.g., "thinspiration" and "fitspiration" trends) on social media might lead to increased feelings of body dissatisfaction which, in turn, can represent a trigger for EDs. We have tested this hypothesis in a sample (N = 721) of young adults (504 females, mean age: 24.13 ± 3.70 years; range 18-34).

METHODS

Self-report measures investigating symptoms related to social media addiction (SMA), muscle dysmorphia (MD), and EDs were used. A mediational model analyzing the direct and indirect effects of SMA-related symptoms on ED-related symptoms through the mediating role of MD-related symptoms was performed controlling for confounding factors (e.g., socio-demographic variables, substances use, body mass index, psychopathological distress).

RESULTS

The model showed that the total effect of SMA-related symptoms on ED-related symptoms was significant (B = 0.213; p = 0.022) and that this association was mediated by MD-related symptoms (B = 0.083; p = 0.021).

DISCUSSION

Our findings support the possibility that MD-related symptoms play a relevant role in mediating the association between SMA severity and ED pathology.

LEVEL OF EVIDENCE

Level III, evidence obtained from well-designed cohort or case-control analytic studies.

Chief Executive Officer Tenacity and Employee Intrapreneurial Behavior: The Mediating Role of Corporate Social Responsibility

Chief executive officer (CEO) tenacity plays an important role in corporate entrepreneurial activity. However, much less is known about its impact on employee intrapreneurship. Drawing from social information processing theory and upper echelons theory, this article examines the hitherto unexplored nexus between CEO tenacity and employee intrapreneurship, as well as the mediating role of corporate social responsibility (CSR). Quantitative data were collected through a survey administered to 294 employees working in different sectors that engage in CSR activities in China. Data analysis was performed using hierarchical regression method through Stata 16.0. It was found that CEO tenacity was significantly positively correlated with employee strategic renewal behavior (β = 0.523, p < 0.001) and employee venture behavior (β = 0.510, p < 0.001). The positive correlation between CEO tenacity and CSR was also significant (β = 0.578, p < 0.001). Besides, CSR partially mediated the relationship between CEO tenacity and employee strategic renewal behavior (40.0%) or employee venture behavior (50.2%). This study extends research on CEO tenacity, CSR, or employee intrapreneurial behavior by providing a better understanding of the direct effects of CEO tenacity on employee intrapreneurial behavior and CSR. From the perspective of cross-fertilization between psychology and management, this study establishes the interface role of CSR by elucidating the intrinsic mechanism of CEOs with high levels of tenacity to stimulate employee intrapreneurial behavior through CSR.

Associations of Face-to-Face and Instant Messaging Family Communication and Their Contents With Family Wellbeing and Personal Happiness Amidst the COVID-19 Pandemic

Background

Both face-to-face and instant messaging (IM) communication are important for families, but face-to-face communication has reduced amidst the COVID-19 pandemic. We examined the use and contents of both communication methods amidst the pandemic, their associations with family wellbeing and personal happiness, and the mediation effects of communication quality in Hong Kong Chinese adults.

Methods

This population-based online survey enrolled 4,921 respondents in May 2020, who reported (i) any face-to-face or IM family communication when the pandemic was severe; (ii) communication contents being classified as neutral, positive, supportive, and negative; and (iii) communication quality, family wellbeing and personal happiness (score 0-10). Associations of family wellbeing and personal happiness with communication methods and contents (no communication excluded) were examined using linear regressions (β), adjusting for each other, sex, age, socioeconomic status, and the number of cohabitants. Mediating effects of communication quality on these associations were examined. Prevalence estimates were weighted by sex, age, and education of the general population. Interactions of methods and contents were examined.

Results

Of 4,891 included respondents (female: 52.9%, 45-54 years: 37.7%, ≥65 years: 21.3%), 7.1% reported no communication, 12.7% face-to-face communication only, 26.7% IM only, and 53.4% both methods. More males and those at younger ages, had lower socioeconomic status, or fewer cohabitants showed no family communication or face-to-face only. More respondents reported neutral (83.1-99.3%) than positive (42.1-62.2%), supportive (37.5-54.8%), and negative (10.9-34.5%) contents despite communication methods. Communication quality was higher with both methods than IM only, face-to-face only, and no communication (scores: 6.7 vs. 4.5-6.6, all P ≤ 0.02). Better family wellbeing and personal happiness were associated with using IM only (adjusted βs: 0.37 and 0.48) and both methods (0.37 and 0.42) than face-to-face only, and positive (0.62 and 0.74) or supportive (0.45 and 0.46) contents (all P ≤ 0.001). Communication quality mediated 35.2-93.5% of these associations. Stronger associations between positive contents and family wellbeing showed in both methods and face-to-face only than IM only (P for interaction = 0.006).

Conclusions

We have first shown that, amidst the COVID-19 pandemic, family IM communication and positive and supportive contents may promote family wellbeing and personal happiness. People with no family communication may need assistance.

Causal relationship of excess body weight on cardiovascular events through risk factors

Excess body weight is associated with cardiovascular events (CVEs) and premature death. This study aimed to find the causal pathways between excess body weight and CVEs through risk factors in a general adult population. A total of 7921 employees of the Electricity Generating Authority of Thailand were enrolled during 1997-2009. Baseline characteristics and blood test results were collected. A body mass index (BMI) ≥ 23 kg/m², using WHO criteria for Asians was defined as excess body weight. A mediation analysis was applied to assess potential causal pathways. BMI ≥ 23 kg/m² was considered as an independent variable, whereas diabetes mellitus (DM), hypertension (HT), and chronic kidney disease (CKD) were considered as mediators, and CVEs (i.e., fatal and non-fatal coronary artery disease or stroke) were considered as the outcomes. The prevalence of BMI ≥ 23 kg/m², DM, HT, and CKD were 62.7%, 7.8%, 28.1% and 11.8% respectively. During an average of 17.2 ± 5.5 years follow-up, subjects with BMI ≥ 23 kg/m² compared with those with lower BMIs more frequently developed CVEs (9.4 vs 6.2%, P < 0.001). The effects of BMI ≥ 23 kg/m² on CVEs were mediated indirectly through DM and HT with significant ORs of 1.61 (1.34, 2.09) and 1.57 (1.39, 1.80), respectively. The indirect effect of CKD on CVEs was significantly increased if mediated through DM → HT or HT [ORs of 1.17 (1.09, 1.32) and 1.20 (1.10, 1.32), respectively]. Subjects with excess body weight were prone to develop CVEs which were mediated indirectly through DM and HT. The effect of CKD on CVEs was small but enhanced if it occurred as a complication of DM or HT.

Physical Self Matters: How the Dual Nature of Body Image Influences Smart Watch Purchase Intention

To determine the role of physical self in body-involving consumption, we explore how body image influences purchasing intention toward hybrid products with body-involving features. In this study, we establish the dual nature of body image: specifically, body image influences intention to purchase via the perception of utilitarian value and symbolic value. Further, we find a competitive mediation in which positive body image (PBI) negatively influences purchase intention (direct effect), while PBI is positively related to purchase intention via utilitarian and symbolic value (indirect effect). This indicates that without the mediation testing of the utilitarian-symbolic framework, the positive influence of body image will be "hidden." Additionally, the mediated effect of symbolic value is moderated by personal innovativeness toward technology (PITT), suggesting that a consumer's knowledge of wearables enhances the effect of body image. With the introduction of body image, this paper provides a more comprehensive model to analyze purchase intention with regard to digital products with body-involving features.

Young women's food consumption and mental health: the role of employment

Objectives

This study explores the relationship between young women’s consumption of healthy and unhealthy food and depression and examines the moderating effect of their employment status on the relationship.

Methods

The National Longitudinal Survey of Youth 79 for Children and Young Adults (NLSY79 CY) was used for this study. The final sample included a total of 1524 young women aged from 18 to 35 years. Multiple Linear Regression was conducted to answer the research questions.

Results

Fast food consumption was related to higher levels of depression among young women while fruit intake was associated with lower levels of depression. Employment status moderated the relationship between young women’s fruit consumption and depression.

Conclusions

Young women are encouraged to consume more fruit and less fast food in order to ameliorate depression. Programs that target young women’s mental health should consider addressing their nutritional needs, through, for example, vouchers for fresh, nutritious foods; nutrition or cooking education; or having a certified nutrition specialist on staff.

How Media Exposure, Media Trust, and Media Bias Perception Influence Public Evaluation of COVID-19 Pandemic in International Metropolises

International metropolises are key sites of outbreaks of COVID-19 cases. Global public evaluation of the pandemic in international cities is affected by many factors. This study examines how media exposure affects this evaluation and how media trust and media bias perception moderate the relationship between them. Based on an online survey of the evaluation of 13 international cities’ pandemic performances by 1171 citizens from 11 countries, this study conducted a multi-level stepwise regression analysis and discovered that: (1) different forms of media affect global citizens’ perceptions of international metropolis COVID-19 pandemic performance differently; and the role of traditional paper media, including newspapers and magazines, is of little significance in comparison to electronic media. (2) Among electronic media, TV and broadcasting have the greatest impact, followed by social media and the Internet. (3) Media trust and media bias perception affect people’s evaluations of international urban pandemics, but our survey reveals that they only function with regard to social media.

What Influences Miners' Safety Risk Perception?

The risks faced by the mining industry have always been prominent for every walk of life in China. As the direct cause of accidents, individual unsafe behaviors are closely related to their risk perception. So, it is important to explore the factors affecting miners’ risk perception and analyze the influencing mechanisms between these factors and risk perception. The questionnaire survey method was used to collect the data of risk perception from nearly 400 respondents working in metal mines in China. Exploratory factor analysis and confirmatory factor analysis were used to analyze and process collected data. The impact of four factors affecting miners’ risk perception was verified, namely: organizational safety atmosphere, organizational trust, knowledge level, and risk communication. Then, regression analysis, Pearson correlation analysis, and structural equation model analysis were used to examine the effect of the four influencing factors on miners’ risk perception. The four influencing factors all have a positive impact on miners’ risk perception; knowledge level has the largest explained variation of miners’ risk perception, followed by risk communication. Organizational trust and organizational safety atmosphere have an indirect and positive impact on miners’ risk perception intermediated by knowledge level and risk communication. The results offer four important aspects of mine safety management to help miners establish quick and accurate risk perception, thereby reducing unsafe behaviors and avoiding accidents.

How Does Corporate Social Responsibility Affect Sustainability of Social Enterprises in Korea?

Social enterprises (SEs) are a new concept, integrating corporate profitability and social purposes. SEs seek to realize sustainable social values, rather than short-term profits. It is therefore important to study the factors that affect the sustainable management of SEs. Corporate social responsibility (CSR) is known to improve corporate image and performance; it can also promote the sustainable development of companies. Innovation has been described as the driving force behind corporate growth and ultimate performance. This study aims to investigate whether CSR can affect sustainability through the economic and social performance of SEs. In addition, it attempts to verify the moderating role of innovativeness in the relationship between CSR and social enterprise (SE) performance. Using survey data from 226 employees of 204 SEs in Korea, we have empirically tested this conceptual framework. The results suggest that, while CSR can improve sustainability through economic and social performance, innovativeness has no moderating effect on the relationship between CSR and SE performance. This study enriches our understanding of the important role played by CSR in driving SE sustainability. It provides new insights into the mechanisms through which SEs can achieve sustainable development. It also contributes to the literature by emphasizing the need for innovation through technical support for SEs.

"I'll Worry About It Tomorrow" - Fostering Emotion Regulation Skills to Overcome Procrastination

Procrastination remains an omnipresent phenomenon impeding especially students' academic performance and well-being. Preliminary findings suggest that procrastination emerges due to dysfunctional emotion regulation efforts to regulate aversive emotions. This study's objective was to clarify whether the enhancement of general adaptive emotion regulation skills reduces subsequent procrastination. For the purpose of this study, data from a two-armed randomized controlled trial (RCT) with (N = 148) university students, comprising an active intervention (IG) and a passive wait-list control (WLC) group, was collected. Participants of the intervention group were provided with an online emotion regulation training over a period of 9 weeks. The results showed that the enhancement of general emotion regulation skills significantly reduced subsequent procrastination behavior within the IG as compared to the untreated WLC. Moreover, subsequent mediation analyses revealed that the reduction of procrastination was significantly mediated by the increase in general ER skills. The present results suggest that trainings which enhance general ER skills are an appropriate measure to reduce procrastination behavior among university students. The practical value of ER training interventions, particularly for student populations, is discussed.

The Influence of Guanxi Between Boundary Spanners on Opportunistic Behaviors Based on the Theory of Reasoned Action Model

This study constructs a mechanism of the influence of Guanxi between boundary spanners on opportunistic behaviors in collaborative innovation projects based on the theory of reasoned action model. The study conducts a survey in the automobile industry in Changchun, Jilin Province, China, and analyzes the research data using the structural equation model. The findings show that Guanxi has a negative an significant influence on opportunistic behavior attitudes and subjective norms., Guanxi has the greater influence on subjective norms than attitudes. Then, opportunistic behavior attitudes and subjective norms positively influence intentions. The influence of subjective norms is stronger. The attitudes and subjective norms of opportunistic behaviors also play mediation roles. Furthermore, opportunistic behavior intentions have a positive and significant influence on behaviors. In short, the study's findings reveal a mechanism of Guanxi between boundary spanners influencing opportunistic behaviors of boundary spanners. It also provides a reference for corporate managers to govern opportunistic behaviors of collaborator while inhabiting opportunistic behaviors of their own boundary spanners.

Stigmatization and Interpersonal Deviance Behaviors of Tour Guides: The Influence of Self-Identity Threat and Moral Disengagement

Severe tour guide stigma is a significant problem hindering tourism development. Based on self-identity threat and moral disengagement theory, this study analyzed the relationship between tour guide stigmatization and tour guides’ interpersonal deviance behavior. Survey data collected from 241 tour guides at three different points in time showed that tour guide stigmatization was positively related to tour guides’ interpersonal deviance behavior and that self-identity threat mediated this effect. The results also show that moral disengagement moderated the effect of tour guides’ self-identity threat on interpersonal deviance behavior, as well as the indirect effect of tour guide stigmatization on tour guides’ interpersonal deviance behavior via self-identity threat. This study enriches theoretical research on tour guide stigmatization and offers practical suggestions for solving stigmatization problems for tour guides and organizations.

Air Pollution, Environmental Violation Risk, and the Cost of Debt: Evidence from China

Although a firm’s exposure to air pollution-related risk has become an important factor that creditors cannot ignore in the procedure of lending decision making with the aggravation of air pollution, empirical evidence on whether and how air pollution affects the cost of debt has been relatively scarce. Employing a series of Chinese listed firms from the main board of the Shanghai and Shenzhen Stock Exchanges covering 2014 to 2018, our research responds to this research gap by exploring how air pollution-induced environmental violation risk affects the cost of debt by constructing an assessment system of firms’ environmental violation risk. The results shed light on an issue that firms exposed to higher concentrations of air pollution may suffer a higher environmental violation risk, resulting in a higher debt cost. In addition, a further analysis shows that environmental regulatory pressure and heavily polluting firms enhance the influence of air pollution on the cost of debt, while state-owned firms and firms’ economic contributions weaken the influence of air pollution on the cost of debt. Our research is conducive to highlighting not only the importance of environmental governance for mitigating the cost of debt to the firms exposed to air pollution, but also its importance to creditors exposed to their clients’ environmental violation risk and default risk.

Gender Differences in Transdiagnostic Predictors of Problematic Alcohol Consumption in a Large Sample of College Students in Ecuador

Background

Alcohol use is one of the main risk factors that leads to detrimental health effects and support for a transdiagnostic approach to alcohol use disorders is growing. However, the role of transdiagnostic predictors of problematic alcohol consumption in Ecuador are understudied.

Objective

The aim of this study was to examine gender differences in psychological stress and inflexibility as transdiagnostic predictors of problematic alcohol consumption in a large sample of college students in Ecuador.

Methods

A total of 7,905 college students (21.49 years, SD = 3.68; 53.75% females) were surveyed using the following standardized scales: Alcohol Use Disorders Identification Test, Perceived Stress Scale-14, and Acceptance and Action Questionnaire (AAQ-7). Macro Process for SPSS (models 4 and 7) was used to analyze mediation and moderation effects.

Results

Reported alcohol consumption was significantly higher in men than women students. On the other hand, women reported significantly higher levels of perceived stress and psychological inflexibility than men students. Gender, age, psychological stress, and inflexibility were significant predictors of alcohol consumption. Moreover, psychological inflexibility mediated the impact of stress on alcohol consumption, particularly in women (for men b = 0.065, 95% CI [0.048 to 0.083], for women b = 0.070, 95% CI [0.051 to 0.089]).

Discussion

Results of this study support psychological stress and psychological inflexibility as critical transdiagnostic variables related to increased rates of alcohol consumption among Ecuadorian college students. These conclusions contribute to the development of transdiagnostic comprehensive programs, which encompasses promotive, preventive, and treatment services that allow to alleviate the burden of alcohol, as well as to enrich the growing research on alcohol consumption in this population from a gender perspective.

Brain conditions mediate the association between aging and happiness

As the population ages, the realization of a long and happy life is becoming an increasingly important issue in many societies. Therefore, it is important to clarify how happiness and the brain change with aging. In this study, which was conducted with 417 healthy adults in Japan, the analysis showed that fractional anisotropy (FA) correlated with happiness, especially in the internal capsule, corona radiata, posterior thalamic radiation, cingulum, and superior longitudinal fasciculus. According to previous neuroscience studies, these regions are involved in emotional regulation. In psychological studies, emotional regulation has been associated with improvement in happiness. Therefore, this study is the first to show that FA mediates the relationship between age and subjective happiness in a way that bridges these different fields.

Exploring the Effect of Parental Styles on Social Skills: The Mediating Role of Affects

Parental educational styles have a significant effect in personal development. These styles (authoritative, democratic, permissive and neglectful) can be related to affects and social skills at the individual level. The study presented here, which comprised 456 participants (151 men; 33.11%), with an average age of 22.01 years (s.d. = 2.80), aimed to analyse the relationship between parental styles, affects and social skills, as well as the role played by affects in the relationship between parental style and social skills. The results suggest that the constructs under study are closely related. The most common parental style is democratic. By gender, permissive styles were more often applied to women and authoritative styles to men. No significant gender differences were found in the application of democratic and neglectful parental styles. In terms of emotional support, women were found to have higher negative affect scores and men higher emotional support scores. People with parents that use democratic and permissive styles scored higher in all variables related to affects and social skills, which challenges the notion that democratic styles are the best parental styles in terms of socialisation of children. The results of the affect and social skills scales were analysed in relation to parenting styles, indicating that children educated under a democratic parental regime tend to yield higher scores in terms of social skills than children educated under any other form of parental regime and medium scores in terms of affects. Finally, it was found that parenting styles have a direct influence on social skills, which tend to improve when affects play a mediating role between these two constructs. These results suggest that parenting styles are closely related to affects and social skills. In addition, they also suggest that affects play a mediating role in the relationship between parenting styles and social skills. Finally, owing to the impact that parenting styles have on affects and social skills, more research is needed to address this issue.
