This study aimed to verify the impact of servant leadership on innovative behaviour in non-governmental organisations (NGOs). It particularly investigated the role of a mediator for self-efficacy in the relationship between servant leadership and innovative behaviour. This study defined the organisational psychology-behaviour mechanism in non-profit organisations by verifying the moderated mediating effect of vocational calling in the relationship between servant leadership, self-efficacy, and innovative behaviour. The 174 pilot samples used in this study comprised community service participants in NGOs. The analysis verified the hypothesis set through causal correlations among four variables using regression analysis and the PROCESS macro developed by Hayes. Vocational calling played a moderating role in the relationship between servant leadership and self-efficacy, and vocational calling had a conditional effect on the impact of servant leadership on innovative behaviour through self-efficacy. Meanwhile, self-efficacy fully mediated servant leadership and innovative behaviour. Based on the verification of the mechanism of organisational psychology-action, this study sought ways to develop the organisation of NGOs and improve the working environment.

Critics argue that service firms should pay more attention to human resource management’s psychological and voluntary aspects to contribute to overall organizational development. The purpose of this study was to investigate the effects of physical self-efficacy on the psychological well-being and organizational citizenship behavior among hotel employees and the moderating effects of leisure-time physical activity on the relationships between the previously mentioned variables. To achieve the research purpose, 346 hotel employees working at the room, food, beverage, and kitchen departments of 10 hotels located in Seoul, South Korea, participated in the study. The researchers visited their department meetings and provided a brief description of the present study and informed consent forms to participate in the study. After obtaining written informed consent forms, the researchers distributed the surveys and asked participants to complete them. Several statistical analyses, including descriptive statistics, confirmatory factor analysis (CFA) for examining the hypothesized model’s psychometric properties, and structural equation modeling (SEM) for testing the hypotheses were conducted using SPSS Ver. 23.0 and AMOS 23.0. Results revealed that perceived physical ability and self-presentation confidence, and psychological well-being positively affected organizational citizenship behavior. Perceived physical ability also had a positive effect on psychological well-being. Lastly, leisure-time physical activity had a partial moderating role in the relationships between the variables mentioned above. This study suggests that promoting employees’ participation in leisure-time physical activity is needed to improve service workers’ organizational citizenship behavior via physical self-efficacy and psychological well-being enhancement.

The COVID-19 pandemic has changed traditional consumer consumption behavior and requires a new service strategy to cope with sustainable consumption. Moreover, it is necessary to focus academic attention on consumer behavior to cook and eat more easily amid Korea’s socioeconomic changes such as the increase in single-person households, aging, rising prices, and continuing economic recession. In this study, we used a revised importance–performance analysis (IPA) to identify specific measures to improve consumer satisfaction with home meal replacements (HMRs). An online survey of Korean adults who had purchased HMRs was conducted based on a convenience sampling method. According to the results, items that could be intensively improved were the ‘introduction of new dishes’, ‘creation of various flavors’, ‘cost-effectiveness, and ‘reasonable price’, whereas ‘easy to prepare’, ‘easily available’, and ‘identified country of origin’ received favorable assessments. With the growth of the non-face-to-face economy due to COVID-19, our findings suggest marketing strategies for sustainable HMR consumption.

We explored the definition of food safety in the coffee service business during the 2019 coronavirus disease (COVID-19) pandemic because consumer values and decision-making may have been affected by the pandemic. The food safety dimensions are freshness, quarantine, hygiene, and healthiness. We evaluated the effects of café food safety on both the consumer intention to revisit a café and their intention to switch to other cafés. We used the Amazon Mechanical Turk system for data collection. In total, 474 individuals responded to the survey questions. We used the statistical package for the social sciences (SPSS) ver. 20.0 and the analysis of moment structure (AMOS) ver. 21.0. We subjected the definition of café food safety to confirmatory factor analysis and then used structural equations to test the research hypotheses. The four dimensions adequately defined food safety. The results indicated that food safety positively influenced the intention to revisit, although it had no significant impact on the intention to switch cafés. Our findings will assist managers because we identify the implications of food safety for the coffee service business.
