The Moderating Effect of Organizational Identification on Occupational Stress and Insomnia Among Nurses

Objective:To explore the relationship between organizational identification,occupational stress,and insomnia among nurses and to analyze the moderating role of organizational identification between occupational stress and insomnia.Methods:Through stratified sampling,720 nurses working in a tertiary A-level hospital in Shandong Province from March to May 2021 were surveyed using an effort-reward imbalance questionnaire,an organizational identification questionnaire,and the Athens Insomnia scale.Results:Organizational identification was negatively correlated with occupational stress and insomnia(r_(1)=-0.121,P_(1)<0.01;r_(2)=-0.144,P_(2)<0.01).Occupational stress was positively correlated with insomnia(r=0.379,P<0.01).Organizational identity significantly moderated nurses’occupational stress and insomnia(β=-0.192,t=-2.558,P<0.05).Conclusion:Occupational stress and organizational identification can predict insomnia.Organizational identification could negatively mediate the relationship between occupational stress and insomnia.Improving organizational identification may help alleviate insomnia symptoms by relieving occupational stress.

Burden of disability in type 2 diabetes mellitus and the moderating effects of physical activity

The growing diabetic epidemic has created a substantial burden,not only on the people with diabetes but also on society at large.This mini-review discussed the limitations and patterns of disability in type 2 diabetes mellitus and put forward a case for the moderating effects of physical activity(PA)in the management of diabetes.The limitations and impairments associated with diabetes include vascular,neurological,cardiac,and renal impairments.Moreover,individuals participate less in their daily lives and in their instrumental activities of daily living,which negatively impacts the quality of life of individuals with diabetes.This often leads to a loss of quality of life due to disabilities,resulting in an increased rate of disability-adjusted life years among people with type 2 diabetes mellitus.Moreover,there are psychosocial sequelae of diabetes mellitus.This necessitates looking for moderating factors that may reduce the burden of the disease.PA has been shown to be one of the factors that can mitigate these burdens.PA does this in several ways,including through the benefits it confers,such as a reduction of hemoglobin A1c,a reduction of excess fat in the liver and pancreas,and the reduction of cardiovascular risk factors,all of which favorably affect glycemic parameters.Specifically,PA regulates or moderates diabetes disability through two mechanisms:The regulation of glucolipid metabolism disorders and the optimization of body mass index and systemic conditions.Therefore,efforts should be directed at PA uptake through identified strategies.This will not only prevent diabetes or diabetes complications but will reduce its burden.

The Effect of a Chocolate Bar Supplementation on Moderate Exercise Recovery of Recreational Runners

To study the effects of a chocolate bar supplementation before exercise on improving recovery of physiological and metabolic changes induced by exercise, 16 male students aged 18-20 years voluntarily served as subjects. A crossover design was employed. Each subject took part in two trials and ran an hour on a treadmill with the intensity of keeping heart rate at 148-150 min for each trial. Results showed that plasma glucose levels of subjects increased significantly (5.42±0.83 mmol/L) at 15 min after ingestion of a chocolate bar and maintained in moderate high levels (4.92 ±0.57 mmol/L) until 30 min after an hour's running while the glucose levels were low and dropped to under normal ranges (3.84 ± 0.31 mmol/L) at 30 min after exercise as they were with a supplement of placebo. Results of plasma FFA, blood lactate and plasma urea nitrogen levels and RPE all indicated that chocolate bar supplementation before exercise benefits to create the necessary prerequisite for exercise and recovery

The Effect of Perceived Anonymity on Online Transgressions:The Moderating Role of Moral Excuses

With the development of science and technology,the use of the Internet is becoming more and more widespread.However,with the popularity of the Internet,some problems have gradually surfaced.The anonymity of Internet use has become a breeding ground for many acts that are contrary to public decency,and this study is conducted against this background.This study explored the impact of perceived anonymity on online transgressions and investigated the moderating effect of moral excuses.A total of 414 subjects,210 males and 204 females,participated in this experimental survey.The SPSS data analysis concluded that perceived anonymity played a significant positive predictive role on online deviance(p<0.01),and the moderating role of moral excuses was not significant.This study will be conducive to the better implementation of the action of clearing cyberspace and to the regulation of public behaviour in cyberspace.

Seeking Health Information Online:The Moderating Effects of Problematic Situations on User Intention

Purpose： This study investigates how online user intention in searching health information is affected by problematic situations.Design/methodology/approach： Based on the Theory of Reasoned Action, the Technology Acceptance Model, and Sense-making theory, we propose two dimensions of problematic situations： urgency and severity of health issues being searched online. Data were collected through a questionnaire survey among 214 Wuhan University students and analyzed using hierarchical regression analysis.Findings： Perceived usefulness, perceived ease of use, and subjective norm can influence user intention to seek health information online. The urgency of problematic situations has a negative moderating effect on the relationship between perceived ease of use and user intention and the relationship between subjective norm and user intention. The severity of problematic situations has a negative moderating effect on the relationship between subjective norm and user intention.Research limitations： The respondents of the survey are limited to students in one Chinese university, so whether this study＇s results can be applied to another population or not remains to be verified. In addition, only two dimensions of problematic situations are considered in this study. Practical implications： The paper puts forward the moderating effect of problematic situations and verifies it, which is the compensation for online health information-seeking behavior research. Besides, our analyses have implications for professional design of health care systems and related consumer information searches, and improve their performance. Originality/value： Previous work has reported the effects of problematic situation on user intention to seek health information online, ignoring its influence on other factors. This empirical study extends that work to identify the influence of problematic situation when seeking intention-behavior data in two dimensions, urgency and severity.

Moderating effect of psychological resilience on the perceived social support and loneliness in the left-behind elderly in rural areas

Objective:To investigate the loneliness and psychological resilience with the perceived social support of the left-behind elderly in rural areas and explore the moderating effect of psychological resilience on the understanding of social support and loneliness of the left-behind elderly in rural areas.Methods:A cross-sectional study was conducted;272 left-behind elderly people in 6 rural villages in the Sichuan Province were investigated by using the General Situation Questionnaire,Perceived Social Support Scale(PSSS),Connor-Davidson Resilience Scale(CD-RISC),and the University of California at Los Angeles Loneliness Scale(UCLA)with a stratified random cluster sampling method.Results:The loneliness score of the left-behind elderly in rural areas was 52.54±7.25,the psychological resilience score was 78(68.87),and the perceived social support score was 57(51.62).The perceived social support and psychological resilience were negatively correlated with loneliness,while the perceived social support was positively correlated with psychological resilience.The moderating effect of psychological resilience on the perceived social support and loneliness of the left-behind elderly in rural areas was−0.102(P<0.001).Conclusions:Higher level resilience is of positive significance to alleviate the negative effect of social support on loneliness.Improving the resilience of the left-behind elderly in rural areas is a beneficial exploration to promote their mental health.

Analysis of the Moderator Effect of RMB Exchange-- Rate on Export The Case of Guangdong Province in China

An important limitation of the research literatures which study the effect on the export of the real effective exchange rates is the lack of application of interaction or moderator effect among the independent variables. To remedy this lacuna, the authors developed a model in which real effective exchange rate moderated the effect of import and utilization of foreign capital on export. The sample comprised 11 years＇ data in Guangdong China. The result showed that real effective exchange rate of RMB affected the export by interacting with utilization of foreign capital. Moreover, to some degree, the real effective exchange rate can also act as moderator between import and export.

Relationship between Parent-Child Attachment and Problem Behaviors among Chinese Firstborn Children in Family Transitions: A Meta-Analysis

The implementation of China’s three-child fertility policy has led to a notable increase in multiple-child families.Notably,firstborn children experience a significant transition from being an only child to a non-only child.This transition is associated with problematic behaviors,affecting their social adjustment,sibling relationships,and family harmony.Although several studies have examined the relationship between parent-child attachment and problem behaviors exhibited byfirstborn children during family transitions,thefindings have been inconsistent.Hence,a meta-analytic study was undertaken to elucidate the inconsistencies in this relationship and explore the moderating factors that may contribute to these discrepancies.Using a systematic literature retrieval and screening method,12 effect sizes were derived from the 10 eligible articles,encompassing a sample size of 5319.The meta-analysis demonstrated a low negative association between parent-child secure attachment and problem behaviors exhibited byfirstborn children during family transitions.Furthermore,the present study investigates potential moderator factors,such as children’s age and geographic region,to gain a more nuanced understanding of the relationship.Consequently,the establishment of parent-child attachment relationships has the potential to mitigate problem behaviors observed infirst-born children during family transitions.The implications of thesefindings indicate that parents can nurture secure attachment bonds with their children by demonstrating sensitive responsiveness,employing positive parenting practices,and fostering emotional availability.These efforts contribute to the cultivation of secure internal working models and positive behavioral manifestations withinfirst-born children,which in turn affect their relationships with siblings.

心理契约对基层全科医师工作绩效的影响机制:离职倾向的中介调节作用

目的 分析心理契约对基层全科医师工作绩效的影响机制,探析离职倾向在其中的中介调节作用,为基层全科医师队伍建设提供依据。方法 采用问卷调查对南京市浦口区基层医疗卫生机构的全科医师进行调研,收集其社会人口学信息,测量其心理契约、工作绩效和离职倾向水平,拟合多重线性回归模型分析作用机制和中介调节效应,验证本研究的4个研究假设。结果 基层全科医师心理契约对工作绩效存在正向促进作用(b=0.554,P<0.001)。纳入离职倾向后,心理契约和队伍稳定性对于工作绩效均存在正向促进作用(b=0.285、0.357,P<0.001)。纳入心理契约和离职倾向的交互项后,交互项的偏回归系数差异具有统计学意义(b=-0.013,P=0.006),说明低离职倾向抑制了心理契约提升工作绩效的正向作用。结论 应重视基层全科医师内在情感(即心理契约)的激励作用,采用多举措降低离职意愿,提升职业认同,避免发生“出工不出力”现象,促进工作绩效提升和基层全科医师队伍稳定。

Protective Factors for Loneliness among Adolescents during COVID-19: Role of the Interpersonal Relationships and Sibling Status

This study examined the moderating effects of parent-child,same-sex,opposite-sex and teacher-student relation-ships between sibling status and loneliness during COVID-19.A total of 1,591 adolescents in China completed the study questionnaires which assessed the aforementioned variables.The results showed that same-sex and teacher-student relationships moderated the association between sibling status and loneliness.The results indicated that among participants with good same-sex relationships during COVID-19,compared to non-only-children parti-cipants,the only-children participants were more likely to experience a lower level of loneliness.However,parti-cipants with poor same-sex relationships experienced similar level of loneliness regardless of whether they had siblings.Thesefindings would be helpful for parents,teachers,and other stakeholders to take effective measures to reduce loneliness feelings among Chinese adolescents.

Digital Transformation, Market Competition, and Corporate Green Technology Innovation

This paper selects China's A-share listed companies from 2012 to 2021 as the research sample and explores the impact of digital transformation on corporate green technology innovation and the moderating role of corporate competitive position in this relationship.The research findings are as follows:Digital transformation plays a significant role in promoting corporate green technology innovation.The improvement of corporate competitive position weakens the promoting effect of digital transformation on corporate green technology innovation.The moderating effect of the corporate competition position is more pronounced in the enterprises of the eastern and western regions,as well as in the listed companies in the manufacturing industry.The promoting effect of digital transformation on utility model patent innovation is dramatically attenuated when the corporate competitive position is strengthened.However,the weakening effect on invention patent innovation is not statistically significant.

Organizational Ambidexterity and Innovation Performance： The Moderating Effect of Entrepreneurial Orientation

The influence of organizational ambidexterity on innovation and the growth of enterprises has gradually become an important research topic in the field of strategic management and organization theory. This paper builds up a theoretical framework of the relationship between organizational ambidexterity and innovation performance with regards to corporate entrepreneurship orientation. We select 175 companies from high and new technology industries in China＇s three large cities, Beijing, Tianjin and Dalian, as samples to carry out an empirical test. We find that the balance and complement of organizational ambidexterity are positively correlated with the innovation performance of enterprises; a corporate entrepreneurial orientation has a significantly moderating effect on the relationship between the balance dimension of organizational ambidexterity and innovation performance, yet it has no significant positive moderating effect on the relationship between the combined dimension oforganizational ambidexterity and innovation performance.

Evaluating the moderating effect of in-vehicle warning information on mental workload and collision avoidance performance

Purpose–The presentation of in-vehicle warnings information at risky driving scenarios is aimed to improve the collision avoidance ability of drivers.Existing studies have found that driver’s collision avoidance performance is affected by both warning information and driver’s workload.However,whether moderation and mediation effects exist among warning information,driver’s cognition,behavior and risky avoidance performance is unclear.Design/methodology/approach–This purpose of this study is to examine whether the warning information type modifies the relationship between the forward collision risk and collision avoidance behavior.A driving simulator experiment was conducted with waring and command information.Findings–Results of 30 participants indicated that command information improves collision avoidance behavior more than notification warning under the forward collision risky driving scenario.The primary reason for this is that collision avoidance behavior can be negatively affected by the forward collision risk.At the same time,command information can weaken this negative effect.Moreover,improved collision avoidance behavior can be achieved through increasing drivers’mental workload.Practical implications–The proposed model provides a comprehensive understanding of the factors influencing collision avoidance behavior,thus contributing to improved in-vehicle information system design.Originality/value–The significant moderation effects evoke the fact that information types and mental workloads are critical in improving drivers’collision avoidance ability.Through further calibration with larger sample size,the proposed structural model can be used to predict the effect of invehicle warnings in different risky driving scenarios.

City size and employment dynamics in China:Evidence from recruitment website data

This article explored China’s urban employment dynamics with particular focus on the city size effect.Big data derived from the largest recruitment website were used to examine the direct and indirect impacts of city size on employment demand by using mediating and moderating models.We also investigated the roles of the government and location factors which have seldom been considered in literature.Results showed that the concentration degree of new jobs is higher than that of stock employment and population across cities,implying a path dependency mechanism of job creation and employment expansion.Meanwhile,numerous job posts in inland central cities are probably a symptom of more even distribution of employment in future China.Econometric models further verified the significant correlation between city size and job creation.Moreover,industrial diversity,fixed asset investment,and spatial location have heterogeneous effects on employment demand in cities of different sizes and different levels of administration.These results can not only deepen our understanding of the crucial role of city size in urban employment growth but also demonstrate the future trend of labor and population geography of China.Policy implications are then proposed for job creation in cities of China and other developing countries.
