Uncovering the dynamics of enterprises digital transformation research: A comparative review on literature before and after the COVID-19 pandemic.

The COVID-19 pandemic has greatly changed global practices of enterprise digital transformation (EDT). However, the impact of the pandemic on EDT research patterns remains unexplored. This study examines the overall development and research pattern shift of literature on EDT in the field of business and economics. A bibliometric analysis with CiteSpace was conducted on a total of 140 journal articles indexed the SSCI and SCIE databases on Web of Science prior to the pandemic and 621 articles published after the pandemic. The results suggest that following the outbreak of COVID-19 pandemic, there has been a significantly rapid growth of EDT-related publications, and the contributing role in EDT research of influential countries has undergone significant changes. Furthermore, the changes in keyword patterns were identified before and after the pandemic. Specifically, EDT research after the COVID-19 outbreak has been focusing on emerging topics, such as corporate governance, sustainable development, platform ecosystems, and dynamic capabilities. Finally, recommendations for future research are provided at individual, organizational, and ecosystem levels. Overall, this study is one of the first studies to uncover the dynamics of EDT research patterns due to the COVID-19 Pandemic, thus enhancing our understanding of the features and structures of digital transformation research in uncertain environment.

Exploring the Complex Relationships Between Factors That Affect Employee Cyberloafing Using a Novel Approach: Findings from Fuzzy-Set Qualitative Comparative Analysis.

Cyberloafing is a workplace problem that has emerged over the past two decades and continues to be problematic as workers' schedules become more flexible and deterrents associated with being physically present in an office are unavailable. Understanding the complex conditions under which employees are more likely to engage in cyberloafing activity continues to be valuable for businesses. This study identifies and models seven conditions that influence cyberloafing and investigates how interconnected social and deterrence factors affect employees' cyberloafing behavior. With a cross-sectional random sample of 324 employees from 14 provinces in China, the necessary condition analysis is used to identify the necessary conditions for high cyberloafing, and the fuzzy-set qualitative comparative approach is conducted to explore the configurational impacts of multiple antecedent conditions on high cyberloafing. The results show that no single condition is necessary for a high level of employee cyberloafing and that three distinct configurations of multiple conditions equivalently contribute to high cyberloafing among employees. Among all configurations, high visibility of cyberloafing, a lack of certainty of formal sanctions, and a lack of reward for not cyberloafing play important roles in explaining employees' cyberloafing. This study is the first to use fuzzy-set qualitative comparative analysis to explore how different combinations of social and reinforcement antecedents contribute to cyberloafing, which goes beyond existing research that explores antecedents independently and offers new insights into cyberloafing's interconnected antecedents and their complex causality.

The biogeography and co-occurrence network patterns of bacteria and microeukaryotes in the estuarine and coastal waters.

Community and diversity shifts of bacteria and microeukaryotes with strong environmental and spatial variations have been unveiled in the Pearl River Estuary (PRE) and northern coastal part of South China Sea (SCS). However, it is not clear what the determining factors shape the microbial community and how the biotic interactions respond to the estuarine and oceanic environment. Here, we established the multiple regression models (MRM) and co-occurrence networks on microbial communities in PRE and SCS habitats. The results showed that there were significant differences of the abiotic factors affecting the bacterial and microeukaryotic communities between PRE and SCS habitats. Salinity explained the largest variations to the microbial community dissimilarities in PRE. Whereas spatial and environmental factors determined the microbial community dissimilarities in SCS. Positive relations between parasitic lineages (e.g. Perkinsea and Cercozoa) and algal taxa (Dinophyceae, Cryptophyta, Chlorophyta and Ochrophyta) dominated in the PRE network. While parasites Syndiniales positively correlated with other Syndiniales and protists in SCS. Strong positive associations among autotrophic and heterotrophic groups were revealed in both niches. Therefore, the biotic interactions are also important and may be responsible for the unexplained variations of the abiotic factors from MRM models. Microbial network in the PRE estuarine water had weakened resistance to environmental disturbances, while the SCS network had greater capacity to maintain network stability. This study shed light on the different mechanisms of abiotic and biotic factors in shaping the compositions of bacteria and microeukaryotes between PRE and SCS niches, and highlights the weakening effect of environmental disturbances on the microbial network stability.

Lose at sunrise, but gain at sunset: Linking social cyberloafing to psychological detachment, personal life enhancement of work, and mental health.

BACKGROUND: Previous research has demonstrated that the personal use of social media, i.e., social cyberloafing, is associated with employee mental health. However, the underlying mechanism through which social cyberloafing is related to mental health has received limited attention. OBJECTIVE: Drawing on conservation of resource theory and work/nonwork enhancement literatures, we developed and tested a model that examines health effect of social cyberloafing. As such, employees' social cyberloafing is posited as positively related to psychological detachment and personal life enhancement of work, which in turn would act as mediators that explain why social cyberloafing improves mental health. METHODS: Data from 375 Chinese employees were analyzed to test research hypotheses using the structural equation modeling and bias-corrected bootstrap method with Mplus 7.4. RESULTS: The results found that social cyberloafing is positively related to psychological detachment, but not with personal life enhancement of work. Social cyberloafing was positively related to employees' mental health through both psychological detachment and through psychological detachment and personal life enhancement of work serially. CONCLUSION: Psychological detachment alone and alongside personal life enhancement of work form part of the mechanisms explaining how and why engaging in social cyberloafing is positively associated with employees' mental health. These mechanisms offer insights to organizations into how the mental health of employees can be improved in the digital workplace.

Exploration of Biomarkers of Psoriasis through Combined Multiomics Analysis.

Background: Aberrant DNA methylation patterns are of increasing interest in the study of psoriasis mechanisms. This study aims to screen potential diagnostic indicators affected by DNA methylation for psoriasis based on bioinformatics using multiple machine learning algorithms and to preliminarily explore its molecular mechanisms. Methods: GSE13355, GSE14905, and GSE73894 were collected from the gene expression omnibus (GEO) database. Differentially expressed genes (DEGs) and differentially methylated region- (DMR-) genes between psoriasis and control samples were combined to obtain differentially expressed methylated genes. Subsequently, a protein-protein interaction (PPI) network was established to analyze the interaction between differentially expressed methylated genes. Moreover, the hub genes of psoriasis were screened by the least absolute shrinkage and selection operator (LASSO), Random Forest (RF), and Support Vector Machine (SVM), which were further performed single-gene gene set enrichment analysis (GSEA) to clarify the pathogenesis of psoriasis. The druggable genes were predicted using DGIdb. Finally, the expressions of hub genes in psoriasis lesions and healthy controls were detected by immunohistochemistry (IHC) and quantitative real-time PCR (RT-qPCR). Results: In this study, a total of 767 DEGs and 896 DMR-genes were obtained. Functional enrichment showed that they were significantly associated with skin development, skin barrier function, immune/inflammatory response, and cell cycle. The combined transcriptomic and DNA methylation data resulted in 33 differentially expressed methylated genes, of which GJB2 was the final identified hub gene for psoriasis, with robust diagnostic power. IHC and RT-qPCR showed that GJB2 was significantly higher in psoriasis samples than those in healthy controls. Additionally, GJB2 may be involved in the development and progression of psoriasis by disrupting the body's immune system, mediating the cell cycle, and destroying the skin barrier, in addition to possibly inducing diseases related to the skeletal aspects of psoriasis. Moreover, OCTANOL and CARBENOXOLONE were identified as promising compounds through the DGIdb database. Conclusion: The abnormal expression of GJB2 might play a critical role in psoriasis development and progression. The genes identified in our study might serve as a diagnostic indicator and therapeutic target in psoriasis.

Bacterial and Protistan Community Variation across the Changjiang Estuary to the Ocean with Multiple Environmental Gradients.

Plankton microorganisms play central roles in the marine food web and global biogeochemical cycles, while their distribution and abundance are affected by environmental variables. The determinants of microbial community composition and diversity in estuaries and surrounding waters with multiple environmental gradients at a fine scale remain largely unclear. Here, we investigated bacterial and protistan community assembly in surface waters from 27 stations across the Changjiang Estuary to the ocean, with salinity ranging from 0 to 32.1, using 16S rRNA and 18S rRNA gene amplicon sequencing. Statistical analyses revealed that salinity is the major factor structuring both bacterial and protistan communities. Salinity also acted as a significant environmental determinant influencing alpha-diversity patterns. Alpha diversity indices for bacterial and protistan communities revealed a species minimum in higher-salinity waters (22.1-32.1). Contrary to the protistan community, the highest bacterial diversity was identified in medium-salinity waters (2.8-18.8), contrasting Remane's Artenminimum concept. The distribution of major planktonic taxa followed the expected pattern, and the salinity boundary for Syndiniales was specifically identified. These findings revealed the significant effects of salinity on the microbial community across an estuary to ocean transect and the distinct response to salinity between bacterial and protistan communities.

The Effect of Perceived Threat Avoidability of COVID-19 on Coping Strategies and Psychic Anxiety Among Chinese College Students in the Early Stage of COVID-19 Pandemic.

Background: The novel coronavirus disease 2019 (COVID-19) outbreak has seriously threatened the mental health of college students. This study intended to invest whether perceived threat avoidability of COVID-19 relates to psychic anxiety among college students during the early stage of the COVID-19 pandemic, as well as the mediating roles of COVID-19-specific wishful thinking and COVID-19-specific protective behaviors in this relationship. Methods: A cross-sectional study was conducted in China, using a random sampling method (February 6-25, 2020). Self-reported questionnaires were conducted online included the Perceived Threat Avoidability of COVID-19 Scale, COVID-19-specific Wishful Thinking Scale, COVID-19-specific Protective Behaviors Scale, and the Hamilton Psychogenic Anxiety Scale. The data were analyzed using Structural equation modeling and Bootstrapping procedure. Results: A total of 2922 samples were collected in this study. Perceived threat avoidability of COVID-19 is negatively related to psychic anxiety (ß = -0.158, p< 0.001), and both COVID-19-specific wishful thinking (ß = -0.006, p = 0.029, 95% CI: [-0.012, -0.001]) and protective behaviors (ß = -0.029, p< 0.001, 95% CI: [-0.043, -0.018]) mediate this relationship. Also, COVID-19-specific wishful thinking is found to correlate with COVID-19-specific protective behaviors negatively (ß = -0.112, p < 0.001). Conclusion: Perceived threat avoidability of COVID-19 contributes to psychic anxiety among college students. COVID-19-specific wishful thinking strategy plays a negative mediating role and increases the level of anxiety; COVID-19-specific protective behaviors strategy plays a positive mediating role and reduces the level of anxiety; meanwhile, wishful thinking also suppresses college students from adopting protective behaviors.

Expression of Serum sLOX-1 in Patients with Non-Small-Cell Lung Cancer and Its Correlation with Lipid Metabolism.

Objective: The aim of this study was to investigate the expression level of soluble LOX-1 (sLOX-1) in the serum of non-small-cell lung cancer (NSCLC) patients and its correlation with lipid metabolism. Methods: 99 inpatients with NSCLC and 81 healthy controls were enrolled in this study. The levels of serum sLOX-1 were compared between the two groups, and the correlation of sLOX-1 with clinicopathological characteristics, blood lipid indices, and carcinoembryonic antigen was analyzed. Results: Compared with the healthy controls, sLOX-1, low-density lipoprotein, triglyceride, and carcinoembryonic antigen in the patients with NSCLC were significantly higher (p < 0.05), while the expression level of high-density lipoprotein was lower (p < 0.05). The expression level of sLOX-1 in the serum of patients with healthy controls was positively correlated with low-density lipoprotein (r = 0.72, p < 0.05). The levels of sLOX-1 and low-density lipoprotein in the serum of patients with NSCLC were closely related to the lymph node metastasis, distant metastasis, and TNM stage (p < 0.05). Compared with a single index, when the sLOX-1 was combined with the CEA, its specificity increased significantly to 97.5% (AUC = 0.995, p < 0.01, 95% CI: 0.989-1.000). Conclusion: sLOX-1 and low-density lipoprotein were overexpressed in the serum of patients with NSCLC, positively correlated, and closely related to the TNM stage and metastasis. This result suggested that lipid metabolic disorders may promote the progression of NSCLC through sLOX-1, which could be a potential serological marker with diagnostic value for NSCLC.

Linking Safety-Specific Leader Reward and Punishment Omission to Safety Compliance Behavior: The Role of Distributive Justice and Role Ambiguity.

Background: Although positive safety leadership has attracted increasingly academic and practical attention due to its critical effects on followers' safety compliance behavior, far fewer steps have been taken to study the safety impact of laissez-faire leadership. Objective: This study examines the relationships between safety-specific leader reward and punishment omission (laissez-faire leadership) and followers' safety compliance, and the mediations of safety-specific distributive justice and role ambiguity. Methods: On a two-wave online survey of 307 workers from high-risk enterprises in China, these relationships were tested by structural equations modeling and bootstrapping procedures. Results: Findings show that safety-specific leader reward omission was negatively associated with followers' safety compliance through the mediating effects of safety-specific distributive justice and role ambiguity. Safety-specific leader punishment omission was also negatively associated with followers' safety compliance through the mediating effect of safety-specific role ambiguity, while safety-specific distributive justice was an insignificant mediator. Originality: The study addresses and closes more gaps by explaining how two contextualized laissez-faire leadership measures relate to followers' safety behaviors, following the contextualization and matching principles between predictors, mediators and criteria, and by revealing two mechanisms behind the detrimental effects of laissez-faire leadership on safety outcomes.

Response Efficacy and Self-Efficacy Mediated the Relationship between Perceived Threat and Psychic Anxiety among College Students in the Early Stage of the COVID-19 Pandemic.

Applying Fear Appeals Theory and Social Learning Theory, this study aims to explore the impact of perceived threat on psychic anxiety among college students in the early stage of the COVID-19 pandemic and the mediating roles of response efficacy and self-efficacy. An empirical study was conducted using an online cross-sectional survey in the early stage of the COVID-19 pandemic in February 2020. A random sampling method was applied to administer questionnaires to 646 Chinese college students. The results showed that: (1) the perceived threat of the COVID-19 pandemic, including perceived susceptibility and severity, was positively correlated with psychic anxiety; (2) self-efficacy mediated the effect of both perceived susceptibility and severity on psychic anxiety, while the response efficacy only mediated the effect of perceived susceptibility on psychic anxiety; and (3) response efficacy and self-efficacy played a serial mediating role on the relationship between perceived susceptibility and psychic anxiety. This study elucidates the relationship between perceived threat and psychic anxiety from the perspective of cognitive appraisal of threat, showing the role positive efficacy appraisal played in reducing psychic anxiety, which could be induced by the perceived threat of major public health emergencies such as COVID-19 pandemic.

The impact of health education videos on general public's mental health and behavior during COVID-19.

BACKGROUND: COVID-19 has seriously affected people's mental health and changed their behaviors. Previous studies for mental state and behavior promotion only targeted limited people or were not suitable for daily activity restrictions. Therefore, we decided to explore the effect of health education videos on people's mental state and health-related behaviors. METHODS: Based on WeChat, QQ, and other social media, we conducted an online survey by snowball sampling. Spearman's non-parametric method was used to analyze the correlation related to mental health problems and health-related behaviors. Besides, we used binary logistic regression analyses to examine mental health problems and health-related behaviors' predictors. We performed SPSS macro PROCESS (model 4 and model 6) to analyze mediation relationships between exposure to health education videos and depression/anxiety/health-related behaviors. These models were regarded as exploratory. RESULTS: Binary logistic regression analyses indicated that people who watched the health education videos were more likely to wear masks (OR 1.15, p < 0.001), disinfect (OR 1.26, p < 0.001), and take temperature (OR 1.37, p < 0.001). With higher level of posttraumatic growth (PTG) or perceived social support (PSS), people had lower percentage of depression (For PSS, OR 0.98, p < 0.001; For PTG, OR 0.98, p < 0.01) and anxiety (For PSS, OR 0.98, p < 0.001; For PTG, OR 0.98, p = 0.01) and better health behaviors. The serial multiple-mediation model supported the positive indirect effects of exposure to health education videos on the depression and three health-related behaviors through PSS and PTG (Depression: B[SE] = - 0.0046 [0.0021], 95% CI - 0.0098, - 0.0012; Mask-wearing: B[SE] = 0.0051 [0.0023], 95% CI 0.0015, 0.0010; Disinfection: B[SE] = 0.0059 [0.0024], 95% CI 0.0024, 0.0012; Temperature-taking: B[SE] = 0.0067 [0.0026], 95% CI 0.0023, 0.0013). CONCLUSION: Exposure to health education videos can improve people's self-perceived social support and inner growth and help them cope with the adverse impact of public health emergencies with better mental health and health-related behaviors.

Do Deterrence Mechanisms Reduce Cyberloafing When It Is an Observed Workplace Norm? A Moderated Mediation Model.

Despite the documented individual, job, and organizational antecedents of cyberloafing at the workplace, few studies have addressed whether, how and when group factors affect employees' cyberloafing behaviors. Drawing on social learning theory and general deterrence theory, the purpose of this study is to test if observability of coworkers' cyberloafing behavior affects employees' perceptions of norms related to cyberloafing and subsequent cyberloafing behaviors and to test if sanctions can play a role in buffering these effects. An investigation of 335 employees working at Chinese enterprises establishes that observing others engaging in cyberloafing influences the employees' perceived norms and cyberloafing behaviors and that employees' perceived norms related to cyberloafing play a partial mediating role in the relationship between observability and employees' cyberloafing. As predicted, we also found that perceived certainty and severity of potential sanctions for cyberloafing moderate the effect of observability on employees' cyberloafing as well as the indirect effect of observability on employees' cyberloafing via perceived norms related to cyberloafing. This study enriched the cyberloafing literature by revealing how observability of cyberloafing influences employees' cyberloafing and by unveiling two boundary conditions under which the cyberloafing learning effect can be buffered.

Effects of Service Recovery Expectation and Recovery Justice on Customer Citizenship Behavior in the E-Retailing Context.

Customer citizenship behavior in the online shopping environment is vital to the success of e-retailers. However, it is unclear whether and how service recovery expectation and recovery justice predict customer citizenship behavior in e-retailing settings. Grounded on the expectation confirmation theory and social exchange theory, this study examined the influence of service recovery expectation and recovery justice on customer citizenship behavior with a serial mediation of recovery expectation confirmation and post-recovery satisfaction. A total of 774 samples from e-shoppers with most impressive (N = 401) and most recent (N = 373) service recovery experience were collected to test the hypotheses using structural equation modeling and bootstrapping procedures. This study reveals that service recovery expectation has a negative impact on recovery expectation confirmation, while recovery justice positively affects recovery expectation confirmation, which is further positively correlated with post-recovery satisfaction and customer citizenship behavior. Moreover, recovery expectation confirmation and post-recovery satisfaction play a serial mediation in the relationship between service recovery expectation and recovery justice, and customer citizenship behavior. Our study contributes to the growing body of customer citizenship behavior literature by offering an alternative perspective (i.e., service recovery) to understand what encourage or impede customer citizenship behavior, and expands service recovery literature by combining service recovery expectation and recovery justice into a framework and revealing the expectation-confirmation mechanism through which they influence post-recovery satisfaction in online shopping setting.

Clinical value of serum and exhaled breath condensate inflammatory factor IL-11 levels in non-small cell lung cancer: Clinical value of IL-11 in non-small cell lung cancer.

OBJECTIVE: Our study aimed to observe and evaluate the clinical value of interleukin (IL)-11 in the serum and exhaled breath condensate of patients with non-small cell lung cancer (NSCLC). METHODS: A total of 91 patients with NSCLC and 72 healthy volunteers were included in this study. IL-11 concentration was determined by ELISA, and the relationship between IL-11 expression in serum and exhaled breath condensate specimens, and the clinicopathological characteristics of patients with NSCLC were analyzed. The relationship between serum IL-11 expression and traditional tumor markers and inflammation indicators of NSCLC was also analyzed. The correlation between serum IL-11 and exhaled breath condensate IL-11 level was determined. The receiver operating characteristic curve was used to evaluate the diagnostic value of IL-11 and carcinoembryonic antigen single and combined detection for NSCLC. The published data from online databases were used to analyze the relationship between the expression of IL-11 and the prognosis of NSCLC. RESULTS: IL-11 concentration in serum and exhaled breath condensate specimens of patients with NSCLC were significantly increased. IL-11 expression was positively correlated with lymph node metastasis, distant metastasis, tumor node metastasis stage, and tumor differentiation degree of NSCLC. The expression of IL-11 in serum was positively correlated with that in exhaled breath condensate specimens. IL-11 expression was closely related to that of neutrophil-to-lymphocyte ratio and carcinoembryonic antigen. The combination of serum IL-11 with exhaled breath condensate IL-11 and carcinoembryonic antigen showed significantly higher diagnostic value than any one marker alone. Besides, the high IL-11 expression was closely related to the poor prognosis of NSCLC. CONCLUSION: IL-11 can be used as a potential diagnostic and prognostic biomarker for NSCLC.

Safety-Specific Passive-Avoidant Leadership and Safety Compliance among Chinese Steel Workers: The Moderating Role of Safety Moral Belief and Organizational Size.

Despite the documented relationship between active-approaching leadership behaviors and workplace safety, few studies have addressed whether and when passive-avoidant leadership affects safety behavior. This study examined the relationship between two types of safety-specific passive-avoidant leadership, i.e., safety-specific leader reward omission (SLRO) and safety-specific leader punishment omission (SLPO), and safety compliance, as well as the moderating effects of an individual difference (safety moral belief) and an organizational difference (organizational size) in these relationships. These predictions were tested on a sample of 704 steel workers in China. The results showed that, although both SLRO and SLPO are negatively related to safety compliance, SLPO demonstrated a greater effect than SLRO. Moreover, we found that steel workers with high levels of safety moral belief were more resistant to the negative effects of SLRO and SLPO on safety compliance. Although steel workers in large enterprises were more resistant to the negative effects of SLPO than those in small enterprises, the SLRO-compliance relationship is not contingent upon organizational size. The current study enriched the safety leadership literature by demonstrating the detrimental and relative effects of two types of safety-specific passive-avoidant leadership on safety compliance and by identifying two boundary conditions that can buffer these relationships among steel workers.

Efficient biosynthesis of exopolysaccharide from Jerusalem artichoke using a novel strain of Bacillus velezensis LT-2.

This study focused on the non-grain biorefining of Jerusalem artichoke (JA) for exopolysaccharide (EPS) efficient production by using Bacillus velezensis LT-2. Results showed that LT-2 could directly utilize JA tuber power (JATP) for EPS production, and its EPS yield reached 11.47 ± 0.33 g/L in the simultaneous saccharification and fermentation (SSF) mode. Furthermore, the SSF mode shortened the fermentation period by 26.67% and reduced the fermentation cost by 79.41% due to the improved substrate utilization and the avoidance of inhibition effects of a high fructose concentration. Transcriptome sequencing results showed that inulin could accelerate nucleotide-sugars biosynthesis, induce EPS synthetic gene cluster transcription, and strengthen the electron transport respiratory chain and the transporter systems, thereby ensuring EPS efficient synthesis. This work exhibited a productive non-grain and environmentally friendly fermentation strategy for EPS biosynthesis, which promoted the JA industry development and created new prospects for high-value industrial products biosynthesis by using JATP.

Role of Farnesoid X Receptor in the Pathogenesis of Respiratory Diseases.

Farnesoid X receptor (FXR) is a bile acid receptor encoded by the Nr1h4 gene. FXR plays an important role in maintaining the stability of the internal environment and the integrity of many organs, including the liver and intestines. The expression of FXR in nondigestible tissues other than in the liver and small intestine is known as the expression of "nonclassical" bile acid target organs, such as blood vessels and lungs. In recent years, several studies have shown that FXR is widely involved in the pathogenesis of various respiratory diseases, such as chronic obstructive pulmonary disease, bronchial asthma, and idiopathic pulmonary fibrosis. Moreover, a number of works have confirmed that FXR can regulate the bile acid metabolism in the body and exert its anti-inflammatory and antifibrotic effects in the airways and lungs. In addition, FXR may be used as a potential therapeutic target for some respiratory diseases. For example, FXR can regulate the tumor microenvironment by regulating the balance of inflammatory and immune responses in the body to promote the occurrence and development of non-small-cell lung cancer (NSCLC), thereby being considered a potential target for immunotherapy of NSCLC. In this article, we provide an overview of the internal relationship between FXR and respiratory diseases to track the progress that has been achieved thus far in this direction and suggest potential therapeutic prospects of FXR in respiratory diseases.
