ABSTRACT
Biofilm formation is a multistep process that requires initial contact between a bacterial cell and a surface substrate. Recent work has shown that nanoscale topologies impact bacterial cell viability; however, less is understood about how nanoscale surface properties impact other aspects of bacterial behavior. In this study, we examine the adhesive, viability, morphology, and colonization behavior of the bacterium Escherichia coli on 21 plasma-etched polymeric surfaces. Although we predicted that specific nanoscale surface structures of the surface would control specific aspects of bacterial behavior, we observed no correlation between any bacterial response or surface structures/properties. Instead, it appears that the surface composition of the polymer plays the most significant role in controlling and determining a bacterial response to a substrate, although changes to a polymeric surface via plasma etching alter initial bacteria colonization and morphology.
ABSTRACT
The COVID-19 outbreak has changed rapidly the business operation and travel behavior of global communities and calls for research on resilience. This study aims to identify the changing destination image of Thailand as a MICE destination during crises and examine the resilience of Thai MICE stakeholders. A mixed method of qualitative and quantitative design was employed using interviews, observations and questionnaire surveys. A longitudinal study of Thai MICE stakeholders during 14 years revealed that the Buddhist concepts of resilience and Thainess contribute to psychological resilience. Buddhism and Thainess cultivate the concept of crisis concierge. Surveys showed unchanged image of exhibition facilities during the political instability. Thailand's incentive travel benefits from the availability of bleisure (a combination of business and leisure) attractions. Good value for money, Thai hospitality, bleisure attractions, and international standard venues are key resilient factors.
