Previous studies have suggested that leadership style may have an impact on job insecurity among employees. Authentic leaders encourage the development of the people around them by practicing real values, beliefs and behaviours, being subordinate oriented and making honest evaluations of the behaviour and performance of employees. Authentic leadership, often considered the ‘root construct’ of other positive leadership forms, conforms to Chinese culture and hence, may be the most suitable leadership style for organizations following this culture. As the effect of authentic leadership on job insecurity is unclear, this study aimed to examine the mechanism between job insecurity and authentic leadership and further explore the mediating effect of psychological empowerment and psychological capital. The results of this study, involving 451 employees from 68 departments of a communications enterprise in China, revealed that authentic leadership has a cross‐level negative impact on employees' job insecurity. Moreover, psychological empowerment and psychological capital played a multiple mediating role between authentic leadership and job insecurity.

COVID-19 is an acute infectious pneumonia, which is a respiratory disease caused by a new coronavirus infection symptom, may combined with mild dry cough, fatigue, poor breathing, diarrhoea and other symptoms, catarrh and other symptoms such as runny nose and sputum are rare (National Health Commission of China). Respiratory droplets and contact transmission are the main

Effective control of the COVID-19 pandemic via appropriate management of the built environment is an urgent issue. This study develops a research framework to explore the relationship between COVID-19 incidence and influential factors related to protection of vulnerable populations, intervention in transmission pathways, and provision of healthcare resources. Relevant data for regression analysis and structural equation modeling is collected during the first wave of the pandemic in the United States, from counties with over 100 confirmed cases. In addition to confirming certain factors found in the existing literature, we uncover six new factors significantly associated with COVID-19 incidence. Furthermore, incidence during the lockdown is found to significantly affect incidence after the reopening, highlighting that timely quarantining and treating of patients is essential to avoid the snowballing transmission over time. These findings suggest ways to mitigate the negative effects of subsequent waves of the pandemic, such as special attention of infection prevention in neighborhoods with unsanitary and overcrowded housing, minimization of social activities organized by neighborhood associations, and contactless home delivery service of healthy food. Also worth noting is the need to provide support to people less capable of complying with the stay-at-home order because of their occupations or socio-economic disadvantage.
