ABSTRACT
The study intends to investigate the role of managerial personality traits on working capital management of Chinese SMEs with the mediating role of overconfidence behavior. Data from the Chinese SMEs managers is collected through a close-ended survey questionnaire using multi-stage cluster sampling and structural equation modeling is applied for empirical analysis. The results shown that extroversion, openness to experience, and agreeableness traits determines overconfidence behavior among the managers. While, conscientiousness and neuroticism traits were found insignificant with overconfidence behavior. Overconfidence behavior significantly mediated during COVID-19 between managerial personality traits (e.g., extroversion and agreeableness traits) and working capital management. Limitted time remained a major limitation in completing this study. The study extended the knowledge by investigating the working capital management practices during COVID-19 in Chinese SMEs and contributed by presenting multiple practical implications for effective working capital management.
ABSTRACT
The distribution of upper respiratory viral loads (VL) in asymptomatic children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown. We assessed PCR cycle threshold (Ct) values and estimated VL in infected asymptomatic children diagnosed in nine pediatric hospital testing programs. Records for asymptomatic and symptomatic patients with positive clinical SARS-CoV-2 tests were reviewed. Ct values were (i) adjusted by centering each value around the institutional median Ct value from symptomatic children tested with that assay and (ii) converted to estimated VL (numbers of copies per milliliter) using internal or manufacturer data. Adjusted Ct values and estimated VL for asymptomatic versus symptomatic children (118 asymptomatic versus 197 symptomatic children aged 0 to 4 years, 79 asymptomatic versus 97 symptomatic children aged 5 to 9 years, 69 asymptomatic versus 75 symptomatic children aged 10 to 13 years, 73 asymptomatic versus 109 symptomatic children aged 14 to 17 years) were compared. The median adjusted Ct value for asymptomatic children was 10.3 cycles higher than for symptomatic children (P < 0.0001), and VL were 3 to 4 logs lower than for symptomatic children (P < 0.0001); differences were consistent (P < 0.0001) across all four age brackets. These differences were consistent across all institutions and by sex, ethnicity, and race. Asymptomatic children with diabetes (odds ratio [OR], 6.5; P = 0.01), a recent contact (OR, 2.3; P = 0.02), and testing for surveillance (OR, 2.7; P = 0.005) had higher estimated risks of having a Ct value in the lowest quartile than children without, while an immunocompromised status had no effect. Children with asymptomatic SARS-CoV-2 infection had lower levels of virus in their nasopharynx/oropharynx than symptomatic children, but the timing of infection relative to diagnosis likely impacted levels in asymptomatic children. Caution is recommended when choosing diagnostic tests for screening of asymptomatic children.
