Increasing Technology-Based Driver’s Productivity Under Covid-19 Pandemic in Vietnam: the Significant Contribution of Consumer Behavior

Purpose: Ride-hailing service, after the emergence in Hanoi – capital of Vietnam in 2014, has experienced major development and gradually enhanced the inner-city travelling of citizens. This study aims at investigating technology-based driver productivity perception and identifying several important influencing factors during the period of COVID-19 pandemic   Design/methodology/approach: The samples of 370 technology-based drivers have been surveyed to collect significant data about factors impacting on worker productivity in Vietnam ride-hailing service. SPSS 26 software is conducted with two types of analyses, including descriptive analysis and statistical analysis   Findings: The findings indicate that social distances, service waste and customer behaviors possess significant impacts on worker productivity in Vietnam ride-hailing services. Several special concerned factors have been identified to raise driver’s awareness of productivity improvement in ride-hailing service.   Research, Practical and Social implication: Major implications can be suggested for improving driver productivity during and after COVID-19 pandemic, especially in term of reducing service waste and increasing customer behavior towards ride-hailing services.   Originality/value: Basing on research findings, the study becomes significant contribution to further papers as well as service managers to enhance technological driver productivity during COVID-19 pandemic.

Newton polytope of good symmetric polynomials

We introduce a general class of symmetric polynomials that have saturated Newton polytope and their Newton polytope has integer decomposition property. The class covers numerous previously studied symmetric polynomials.Comment: 10 pages, 3 figure
