This study aimed to explore the impacts of COVID-19 on car and bus usage and their relationships with land use and land price. Large-scale trip data of car and bus usage in Daejeon, South Korea, were tested. We made a trip-chain-level data set to analyze travel behavior based on activity-based travel volumes. Hexagonal cells were used to capture geographical explanatory variables, and a mixed-effect regression model was adopted to determine the impacts of COVID-19. The modeling outcomes demonstrated behavioral differences between associated with using cars and buses amid the pandemic. People responded to the pandemic by reducing their trips more intensively during the daytime and weekends. Moreover, they avoided crowded or shared spaces by reducing bus trips and trips toward commercial areas. In terms of social equity, trips of people living in wealthier areas decreased more than those of people living in lower-priced areas, especially trips by buses. The findings contribute to the previous literature by adding a fundamental reference for the different impacts of pandemics on two universal transportation modes.

Purpose Despite recent advances in research on antecedents of social entrepreneurial intentions, founder social identity has rarely been part of the research effort. This paper aims to investigate how different types of founder social identity affect social entrepreneurial intentions (SE intentions). Design/methodology/approach This study investigates how different types of founder social identity, such as Darwinians, Communitarians and Missionaries, affect SE intentions. Specifically, this study predicts that entrepreneurs with Darwinian identity would be less likely to form SE intentions, while those with Missionary and Communitarian identities would be more prone to form SE intentions. The hypotheses are tested on a sample of 725 individuals recruited using Amazon Mechanical Turk. Most of the hypotheses, except for Communitarian identity, are supported by the data analysis. The results contribute to the literature on founder social identity and SE intentions and demonstrate that founder social identity is one of the important antecedents of social entrepreneurial intentions. Findings Two of the hypotheses were supported by the results. Specifically, this study found a positive relation between Missionary founder social identity (its locus of self-definition is “Impersonal-We”) and social entrepreneurial intentions. This research also confirms that Darwinian founder social identity (its locus of self-definition is “I”) has a negative impact on social entrepreneurial intentions. Originality/value First, a person’s social identity has been largely overlooked in social entrepreneurship intention literature (Bacq and Alt, 2018; Hockerts, 2017; Zaremohzzabieh et al, 2019). The findings provide the empirical evidence that individual-level antecedents, especially one’s membership in a social group (i.e. social identity), exert a significant impact on the formation of SE intentions. Second, among the two types of founder social identity predicted to have a positive influence on SE intentions, only Missionary identity was found to have such a positive impact. The typical Communitarian locus of self-definition of “Personal We,” is less influential than the self-definition of the typical Missionary locus of “Impersonal We.” This might imply that not all types of feelings of belonging to a community have a positive impact on the formation and development of social entrepreneurial intentions. Finally, this study found that Darwinians are less likely to pursue social entrepreneurship although the definition of Darwinians is close to the definition of traditional entrepreneurs (e.g. profit/opportunity seekers). This may signify that the traditional concept of entrepreneurship may not be enough to explain different types of entrepreneurial motivations (e.g. social vs commercial entrepreneurship).

Shared mobility is a service that allows users to share various transportation modes and use them with reservations when necessary. It started with private automotive car-sharing and ride-sharing services. Currently, it operates on a wider range, including personal mobility devices such as electric bicycles and scooters. The purpose of this study is to derive a direction for providing future shared mobility services through analysis of factors affecting the usage intention of both current and prospective users. The survey targets 753 citizens living in Gyeonggi Province, Korea. The survey period is from February 12, 2020, to February 26, 2020. In this study, a logistic regression analysis is conducted to investigate the factors affecting the use intention of shared mobility. The analysis results show that gender, car ownership, and education, among variables reflecting socio-demographic characteristics, have significant effects on intention to use shared mobility. Moreover, we find that experience factors, including mainly used transportation modes, ownership of shared mobility device, past experience in similar services, satisfaction of existing shared mobility services, and distance from the home to the nearest bus stop, are also statistically influential. The analysis results are expected to lay the foundation for the introduction of shared mobility services and can be used as data for planning smart mobility services in the future.

Purpose This study aims to investigate how three critical governance decisions by foreign firms impacted their survivability post-initial public offerings (IPO): the choice of CEO (founder vs non-founder); the power the founder CEO wields relative to the board in terms of CEO duality; and board size. Design/methodology/approach This study uses data from 86 foreign firms that completed IPOs in the US market between 2000 and 2008 and adopts a Cox proportional hazards model to examine how the founder, founder CEO duality and board size influence foreign firm delisting post-IPO. Findings A founder CEO or a founder CEO with duality (i.e. when a founder CEO is also chair of the board of directors) does not support a foreign firm’s survival post-IPO. Expectedly, board size has a negative impact on post-IPO firm survivability; however, founder CEO duality positively moderates this negative relationship. Therefore, founder CEO duality plays a positive indirect role in the context of post-IPO firms with large boards. Originality/value First, while the benefits of CEO duality have been empirically ambiguous, this study clarifies how founder CEO duality manifests its positive impacts in foreign listings. Second, by focusing on board cognition, this study confirms the negative impact of large boards, but highlights that this can be mitigated by governance leadership structure. Finally, despite organizational life-cycle theorists’ advocacy of the replacement of founder CEOs with professional CEOs in sizable ventures, this study shows the benefits of their retention when the board is large.

Purpose This study aims to understand how social experience influences social entrepreneurial (SE) intentions through different types of self-referent beliefs and how gender affects this mechanism. Design/methodology/approach To test this study’s conceptual model, the authors conducted an online survey and recruited respondents via Amazon’s Mechanical Turk. This study’s analysis is based on 743 responses. This study used structural equation modeling to test the main hypotheses, conducted decomposition tests using the bootstrapping method to test mediation effects via self-referent beliefs and executed multi-group analyses to examine gender-moderated mediation effects. Findings The results confirm that social experience significantly influences all three types of self-referent beliefs (entrepreneurial self-efficacy, SE self-efficacy and self-esteem). Furthermore, the mediating relationship across social experience, self-efficacies, and SE intentions is moderated by gender, as the relationships between social experience and self-efficacies are stronger for women than for men. Originality/value A clear gender gap exists in the way how social experience affects perceptual variables (self-referent beliefs), providing a practical suggestion to reduce the perceptual gender gap in social entrepreneurial contexts. This study also reveals the mediating mechanism across social experience, self-efficacies and SE intentions, also highlighting the importance of domain specific self-efficacies. This study’s findings support and extend Milliken’s (1987) framing of three distinct types of uncertainty to explain how individuals form SE intentions.

The aim of this study was to evaluate nutritional care and outcomes in a medical intensive care unit (ICU) following multidisciplinary nutritional team (MNT) involvement. The authors retrospectively reviewed the data of all patients admitted to a medical ICU from April to October 2013 (pre-MNT period) and from April to October 2014 (post-MNT period). In total, 140 patients were included and allocated to the pre-MNT group (n=70) or the post-MNT group (n=70). The post-MNT group was more likely to use enteral nutrition (61.4 vs 37.1%, P=0.002). In terms of total calories and protein provided, the number of nutritional goal-achieved days during stays in ICU was significantly greater in the post-MNT group than in the pre-MNT group (63.7% vs 47.6%, P<0.05 and 44.3% vs 29.9%, respectively, P<0.05). The MNT activities resulted in significant improvements in terms of nutritional provision and adequacy in a medical ICU.
