The COVID-19 pandemic at the beginning of 2020 has changed the conventional learning mode for most students at schools all over the world, and the e-learning at home has become a new trend. Taking Chinese college students as the research subject and drawing on the stimulus–organism–response model, this paper examines the relationship between the peer referent, perceived closeness, and perceived control and the learning engagement. Using data from 377 college students who have used e-learning, this study shows that perceived closeness, (...) perceived control, and peer referents in e-learning have a positive effect on the self-efficacy and well-being of students, thus improving students’ enthusiasm for learning. Our intent is to assist researchers, instructors, designers, and others in identifying effective methods to conceptualize and measure student engagement in e-learning. (shrink)

We used social network analysis to examine a theoretical model exploring why, and under what circumstances, the perpetrators’ ostracizing behaviors are accurately perceived by the target employees. In turn, these perceptions of ostracism lead to the target employees’ counterproductive work behaviors. Adopting perspectives from both perpetrators and targets, we directly measured the ostracizing behaviors by all potential perpetrators and perceived workplace ostracism by target employees. We integrate Social information processing theory and conservation of resource theory to propose a moderated mediation (...) model, and found that employees who have a high level of need to belong are more likely to capture coworkers’ ostracizing behaviors, and those with low political skill are more likely to engage in counterproductive work behavior as their reaction to perceived workplace ostracism. Theoretical and practical implications are discussed. (shrink)

The purpose of this study is to investigate the current state of post-traumatic growth and identify its influencing factors in discharged COVID-19 patients. PTG refers to individual experiences of significant positive change arising from the struggle with a major life crisis. This descriptive cross-sectional study used the convenient sampling method to recruit 140 discharged COVID-19 patients in Hunan, China. The results show that the PTG of the discharged COVID-19 patients was positively correlated with self-esteem, post-traumatic stress disorder, coping style tendency, (...) and social support, but negatively correlated with the time from onset to diagnosis. Our findings could provide guidance on improving the psychological state and well-being of discharged COVID-19 patients. (shrink)

Memory modification technology (MMT) refers to the use of neurotechnologies to intervene in memories. Many scholars have reflected on the ethical issues in MMT, but a comprehensive review of this topic has not been seen. This article presents the first scoping review study of ethical issues in MMT using a bibliometric and systematic approach. After thorough examination, 133 records of key literature are included in this scoping review. Six core ethical themes are extracted: (1) self, identity, and authenticity; (2) autonomy (...) and informed consent; (3) welfare and happiness; (4) safety and risks; (5) responsibility and obligation; (6) social and legal justice. More detailed analyses are conducted on the moral stances and reasons held by different scholars concerning these ethical themes. As can be seen, current debates exhibit certain shortcomings, including ambiguous ethical concepts and a restricted scope of analysis. Therefore, we call for deeper reflections on the philosophical foundations, more precise definitions of ethical terms, and more comprehensive examinations of neurotechnological applications, in order to better address the ethical challenges in the future.

BackgroundMental stress and imbalance of its two neural stress systems, the autonomic nervous system and the hypothalamic–pituitary–adrenal axis, are associated with chronic prostatitis/chronic pelvic pain syndrome and erectile dysfunction. However, the comprehensive analyses of psychological stress and stress systems are under-investigated, particularly in CP/CPPS patients complicated by lower urinary tract symptoms and ED.Materials and methodsParticipants were 95 patients in CP/CPPS+ED group, 290 patients in CP/CPPS group, 124 patients in ED group and 52 healthy men in control group. The National Institutes (...) of Health Chronic Prostatitis Symptom Index, the International Index of Erectile Function-5 and the International Prostate Symptom Score were used for assessing the disease severity of CP/CPPS, LUTS and ED. Psychometric self-report questionnaires including the Beck Anxiety Inventory, Perceived Stress Scale, Type A Personality Test and Symptom Checklist 90 were completed for distress from physical symptoms. Twenty-five subjects per group were randomly selected for further investigating the changes of the HPA axis and ANS. Saliva samples were taken on 3 consecutive days at 8 specific times with strict reference to time of morning awakening for evaluation of free cortisol. Heart rate variability as marker of the ANS was measured using 24 h electrocardiography, and time-and frequency-domain variables were analyzed.ResultsThe BAI and SCL-90 scores were significantly higher in the CP/CPPS+ED, CP/CPPS and ED groups compared with the control group. The PSS scores of both groups with ED were significantly higher than the control group. Compared with the CP/CPPS group, the differences of PSS, SCL-90 and TAPT scores were statistically significant in CP/CPPS+ED patients. The IPSS scores were shown to have significantly positive correlations with BAI, PSS and SCL-90 in the CP/CPPS patients. However, in all subjects, the IIEF-5 scores were shown to have significantly negative correlations with BAI, PSS, SCL-90 and quality of life score in NIH-CPSI. Cortisol awakening response parameters and diurnal cortisol levels did not significantly vary between the four groups. Time-dependent parameters of HRV also did not differ significantly across groups. In the frequency domain analysis, low frequency was significantly lower in ED patients when compared with CP/CPPS+ED patients and healthy controls, high frequency power was significantly higher in healthy controls compared to patients with ED, CP/CPPS and CP/CPPS+ED, and the CP/CPPS+ED group had significantly higher LF/HF ratio than the control group.ConclusionCP/CPPS and ED patients score exceedingly high on most psychosocial variables. The symptom scores of LUTS and ED positively correlate with the severity of psychological stress. Our findings also suggest that the ANS sympathovagal imbalance is associated with ED and LUTS in CP/CPPS, whereas HPA axis activity is not. (shrink)

In complex systems, agents often interact with others in two distinct types of interactions, pairwise interaction and group interaction. The Deffuant–Weisbuch model adopting pairwise interaction and the Hegselmann–Krause model adopting group interaction are the two most widely studied opinion dynamics. In this study, we propose a novel opinion dynamics by combining pairwise and group interactions for agents and study the effects of the combination on consensus in the population. In the model, we introduce a parameter α to control the weights (...) of the two interactions in the dynamics. Through numerical simulations, we find that there exists an optimal α, which can lead to a highest probability of complete consensus and minimum critical bounded confidence for the formation of consensus. Furthermore, we show the effects of α on opinion formation by presenting the observations for opinion clusters. Moreover, we check the robustness of the results on different network structures and find the promotion of opinion consensus by α not limited to a complete graph. (shrink)

BackgroundCognitive behavioral therapy has well-characterized benefits in alleviating diseases associated with depression, anxiety, and obesity, resulting in a marked improvement in the patient’s quality of life. There are some studies regarding the effects of CBT on patients with polycystic ovary syndrome. However, there is still no report of a meta-analysis for systematic assessment.ObjectivesThis study aimed to evaluate the effectiveness of CBT in improving weight loss, anxiety, depression, life quality, compliance, and pregnancy outcomes in patients with PCOS.MethodsStudies regarding CBT related to (...) PCOS in PubMed, Cochrane library, Embase, ClinicalTrials.gov, CNKI, and WANFANG DATA were searched for up to 19 November 2020. A random-effects model was used to perform a meta-analysis.ResultsEight trials regarding CBT compared with lifestyle modification and routine treatments were included. No differences in depression, body mass index, or overall life quality were evident between CBT and control groups; however, anxiety and quality of life in hirsutism were significantly improved. For secondary outcomes, both patient compliance and pregnancy rate were improved, but no significant change in pregnancy loss rate was identified.ConclusionCBT exhibited obvious advantages in the alleviation of anxiety, improvement of quality of life in hirsutism, and increase of compliance and pregnancy rate in patients with PCOS. Larger and higher-quality randomized controlled trials are needed to clarify the role of CBT in PCOS.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42021225856].

This longitudinal case study identifies corporate governance responses in a Chinese state-owned enterprise facing institutional logic multiplicity and demands to shoulder sociopolitical responsibilities beyond economic responsibility. We find that overseas listing led to the incorporation of market logic into an enterprise in which party-state logic prevailed. The prioritization of sociopolitical responsibilities vis-à-vis economic responsibility has shifted through three phases, reflecting changes in institutional logic centrality amid changing politico-institutional and firm conditions. In response, the enterprise developed hybrid corporate governance structures based (...) first on decoupling (2001–2011) and then on translation of a “foreign” corporate governance model to fit the domestic context (2012–2016) but has since sought to dehybridize by strengthening the state-controlled governance structure (2017–2019). Our study contributes to the varieties-of-capitalism approach to corporate governance and offers perspectives on institutional change, institutional logic, and hybrid organizing as well as the implicit ethical issue.

Students’ active learning behavior determines learning performance. In post-COVID-19 period, Online Merging Offline method become a common way of university students’ learning. However, at present, there are few studies in active learning behavior in the OMO mode. Combined with learning satisfaction and Technology Acceptance Model, this paper proposes an Online Active Learning Model to predict the influencing factors of college students’ active learning behavior and then analyzes the differences between OMO model and pure online model by multi-group analysis based on (...) the model. The designed questionnaire was distributed, and a total of 498 valid questionnaires were collected. Using SmartPLS to analyze partial least squares structural equation modeling and MGA, it is found that: there are differences in the influencing factors of active learning between OMO and pure online model; the moderating effect of learning complaint in OMO mode is not established, and social isolation and age does not affect active learning in OMO mode; learning quality, perceived ease of use, expectation, perceived usefulness, and social isolation indirectly affect active learning through learning satisfaction in both OMO model and pure online model; learning satisfaction is an important mediating variable affecting active learning; and learning complaints will negatively regulate the relationship between learning satisfaction and active learning only in pure online model. According to these findings, the paper provides theoretical and practical implementation suggestions implications for OMO teaching and OAL to ensure the expected learning outcome. (shrink)
