The influence of spiritual leadership on the subjective well-being of Chinese registered nurses.

BACKGROUND: Challenging working conditions and job characteristics can result in nurses experiencing significant workplace stress and adversity. AIM: To examine how and why spiritual leadership may have a positive influence on nurses' subjective well-being. METHOD: A total of 339 registered nurses from five public hospitals in Mainland China participated in this study. Hypotheses were tested using the PROCESS macro. RESULTS: Spiritual leadership influenced the subjective well-being indirectly through workplace spirituality. The interaction between spiritual leadership and power distance orientation on workplace spirituality was significant. Power distance orientation moderates the indirect effect of spiritual leadership on the subjective well-being through workplace spirituality, and this indirect effect is more positive for nurse with lower power distance orientation. CONCLUSIONS: Spiritual leadership is a significant contextual factor in the workplace that may influence the nurses' workplace spirituality and subjective well-being. Based on their power distance orientation, nurses may have different responses to spiritual leadership, resulting in differing levels of workplace spirituality. IMPLICATIONS FOR NURSING MANAGEMENT: Spirituality can satisfy the internal needs of nurses. Spiritual leadership can facilitate a spiritual working context for sustaining the subjective well-being of nurses. Hospitals should provide training programmes to help existing leaders engage in spiritual leadership.

Narrowing the creativity gap: the moderating effects of perceived support for creativity.

This article examines the role of 3 types of perceived support for creativity in moderating the relation between creative self-efficacy and self-perceived creativity. The findings suggest significant interaction effects for perceived work-group support and supervisor support, but not for perceived organizational support. This study is among the first to (a) examine the importance of perceived support for creativity in unlocking creative potential and increasing creativity in organizations and (b) use interaction terms in structural equation modeling (SEM) to investigate moderator effects in an applied research setting. These results imply that organizational interventions focused on training supervisors and work-group members to support creativity in the workplace may be more effective than broader and less focused interventions at the organizational level.

How Trust in Information Sources Influences Preventative Measures Compliance during the COVID-19 Pandemic.

This paper explores how trust in formal information sources (government and media) and informal information sources (interpersonal) about COVID-19 influences compliance with preventive measures. This cross-sectional study uses convenience sampling of 478 adult participants. Data analyses using structural equation modeling with multigroup comparisons examine hypothesized relationships between trust in information sources and preventative behaviors and social distancing. Results suggest that understanding of COVID-19 causes is related to trust in formal information sources, but not to trust in informal information. Self-efficacy for prevention is related to trust in informal information sources, but not to trust in formal information sources. Worry about contracting COVID-19 is related to trust in formal information sources, but not to informal ones. Engaging in preventive measures is linked to both self-efficacy for prevention and worry, while social distancing was related only to worry. These findings have important implications for public health policy guidelines centered on clear and truthful media messages. The findings also facilitate comparative analyses of reactions to information sources across a decade of evolving attitudes toward media and government, between two cultures (Hong Kong vs. the USA), and between two different global pandemics.

Perceived organizational support and turnover intention: the mediating effects of personal sacrifice and job fit.

This study examines the mediating role of job fit on the relationship between perceived supervisor support (PSS) and perceived organizational support (POS), and the mediating role of personal sacrifice on the relationship between POS and turnover intention. We use structural equation modeling (SEM) with a data set consisting of a sample of 346 individuals in a manufacturing firm to test our proposed model of PSS, POS, and turnover intention. Consistent with prior literature, our hypothesized model confirms that PSS is a predictor of POS and that POS is a predictor of turnover intention. By testing two additional competing and theoretically derived nested models, our findings indicate that job fit partially mediates the relationship between PSS and POS, and that personal sacrifice partially mediates the relationship between POS and turnover intention. Our study is among the first to examine job fit and personal sacrifice as mediators within the POS-turnover intention model.

Self-leadership and stress among college students: Examining the moderating role of coping skills†.

Objective: Stress remains a major health concern among college students today. Consequently, research on student stress is imperative, from both an organizational and an individual perspective. This research study explores the moderating role of coping skills on the relationship between self-leadership and stress among college students. Participants: Data from 643 full-time undergraduate students attending a 4-year public university in the mid-Atlantic region were collected in February 2017 and analyzed using a moderated regression model. Results: The results indicate self-leadership practices do reduce student stress levels and that this relationship is moderated by student coping skills. Conclusion: The findings from this study deepen our understanding of how self-leadership practices may decrease student stress and showcases self-leadership as an effective tool for reducing college student stress.

Novel insight into mutational landscape of head and neck squamous cell carcinoma.

Development of head and neck squamous cell carcinoma (HNSCC) is characterized by accumulation of mutations in several oncogenes and tumor suppressor genes. We have formerly described the mutation pattern of HNSCC and described NOTCH signaling pathway alterations. Given the complexity of the HNSCC, here we extend the previous study to understand the overall HNSCC mutation context and to discover additional genetic alterations. We performed high depth targeted exon sequencing of 51 highly actionable cancer-related genes with a high frequency of mutation across many cancer types, including head and neck. DNA from primary tumor tissues and matched normal tissues was analyzed for 37 HNSCC patients. We identified 26 non-synonymous or stop-gained mutations targeting 11 of 51 selected genes. These genes were mutated in 17 out of 37 (46%) studied HNSCC patients. Smokers harbored 3.2-fold more mutations than non-smokers. Importantly, TP53 was mutated in 30%, NOTCH1 in 8% and FGFR3 in 5% of HNSCC. HPV negative patients harbored 4-fold more TP53 mutations than HPV positive patients. These data confirm prior reports of the HNSCC mutational profile. Additionally, we detected mutations in two new genes, CEBPA and FES, which have not been previously reported in HNSCC. These data extend the spectrum of HNSCC mutations and define novel mutation targets in HNSCC carcinogenesis, especially for smokers and HNSCC without HPV infection.

Activation of the NOTCH pathway in head and neck cancer.

NOTCH1 mutations have been reported to occur in 10% to 15% of head and neck squamous cell carcinomas (HNSCC). To determine the significance of these mutations, we embarked upon a comprehensive study of NOTCH signaling in a cohort of 44 HNSCC tumors and 25 normal mucosal samples through a set of expression, copy number, methylation, and mutation analyses. Copy number increases were identified in NOTCH pathway genes, including the NOTCH ligand JAG1. Gene set analysis defined a differential expression of the NOTCH signaling pathway in HNSCC relative to normal tissues. Analysis of individual pathway-related genes revealed overexpression of ligands JAG1 and JAG2 and receptor NOTCH3. In 32% of the HNSCC examined, activation of the downstream NOTCH effectors HES1/HEY1 was documented. Notably, exomic sequencing identified 5 novel inactivating NOTCH1 mutations in 4 of the 37 tumors analyzed, with none of these tumors exhibiting HES1/HEY1 overexpression. Our results revealed a bimodal pattern of NOTCH pathway alterations in HNSCC, with a smaller subset exhibiting inactivating NOTCH1 receptor mutations but a larger subset exhibiting other NOTCH1 pathway alterations, including increases in expression or gene copy number of the receptor or ligands as well as downstream pathway activation. Our results imply that therapies that target the NOTCH pathway may be more widely suitable for HNSCC treatment than appreciated currently.

Differential angiogenic regulation of experimental colitis.

Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders of the intestinal tract with unknown multifactorial etiology that, among other things, result in alteration and dysfunction of the intestinal microvasculature. Clinical observations of increased colon microvascular density during IBD have been made. However, there have been no reports investigating the physiological or pathological importance of angiogenic stimulation during the development of intestinal inflammation. Here we report that the dextran sodium sulfate and CD4+CD45RBhigh T-cell transfer models of colitis stimulate angiogenesis that results in increased blood vessel density concomitant with increased histopathology, suggesting that the neovasculature contributes to tissue damage during colitis. We also show that leukocyte infiltration is an obligatory requirement for the stimulation of angiogenesis. The angiogenic response during experimental colitis was differentially regulated in that the production of various angiogenic mediators was diverse between the two models with only a small group of molecules being similarly controlled. Importantly, treatment with the anti-angiogenic agent thalidomide or ATN-161 significantly reduced angiogenic activity and associated tissue histopathology during experimental colitis. Our findings identify a direct pathological link between angiogenesis and the development of experimental colitis, representing a novel therapeutic target for IBD.
