The present study focuses on the construct of entrepreneurial alertness, investigating the external antecedents of the construct, responding to the call for more research pledged by Tang, Kacmar, and Busenitz (2012). Namely, we examine how receiving feedback, awards and collaboration offers in relation to an individual’s hobby activity influences the development of entrepreneurial alertness dimensions. Additionally, we make a contribution by testing the effect of these external factors in a non-entrepreneurial context of homebrewing communities, that is individuals producing beer at home as a hobby. In line with other form of craft activities, this context has demonstrated a high potential for business start-up development due to the increasing number of new small brewing businesses in North America run by entrepreneurs that were previously homebrewers (Carroll & Swaminathan, 2000). We test our tenets within the complexity theory, where configurations of antecedents are examined in order to gain deeper understanding of the possible outcome (Woodside, 2014), using 213 completed questionnaires. We apply fuzzy-set qualitative comparative analysis (fsQCA, Ragin 2000; 2008) to achieve a holistic overview of the examined interrelationships (Ordanini, Parasuraman & Rubera, 2015). We find that high feedback is a sufficient condition for high scanning and search, association and connection, as well as evaluation and judgement activities of entrepreneurial alertness. Without feedback, people at the hobby stage engage in their leisure activities solely because they like it. However, receiving feedback in relation to their hobby outcomes provides an opportunity for individuals to develop and experience additional motivations beyond enjoyment, where they understand that the hobby could be commercialized and bring monetary rewards. Moreover, we find that an individual receiving low amount of awards but high amount of collaboration offers may also have high entrepreneurial alertness. Since individuals receive rewards related to the excellent performance in their leisure activity, it may not provide any cue for a potential transformation into a business. However, the more collaboration offers people receive, the more likely they get involved in scanning and search, association and connection, and evaluation and judgement activities of entrepreneurial alertness. Therefore, they are likely to conduct additional search, connect bits of available information and evaluate this business opportunity (Gaglio & Winter, 2009). The findings of this study could help entrepreneurs reflect on their decisions and behaviours during the business start-up planning process, and measure their entrepreneurial alertness and the extent of readiness to engage in business venturing.

The paper investigates the Brain Drain in Chinese family business based on a sample of 319 family businesses in China. Using a fuzzy set qualitative comparative analysis (fsQCA) to uncover different combinations of conditions (pay and welfare, work environment, management style of the leaders, and career planning) that are sufficient to achieve high and low brain drain. The results show that pay and welfare is a necessary but not a sufficient condition by itself to achieve high brain drain. The findings show that three causal recipes are equifinal in achieving high brain drain. The first causal recipe combines high work environment with low level of career planning and with high pay and welfare. The second combines low work environment with high level of career planning and with high pay and welfare. Finally, the third combines high work environment with high level of management style of the leaders and with high pay and welfare. The study also found two causal configurations that are equifinal to achieve low brain drain. Moreover, these combinations are not a mirror of the combinations founded for high brain drain. This study offers several implications to both researchers and business practitioners: It is acquired that in order to prevent brain drain, the pay and welfare of employees should be raised while the management philosophy should pay attention to humans in the first place. Secondly, the leaders need to improve their own quality so as to strengthen the management of family businesses. Finally, a refined human resource system needs to be established. After brain drain, enterprises should perfect their contract constraining mechanism and, bring in suitable talents promptly so that the loss is minimised.

This study addresses the influence of corruption on firm innovation in Chinese market. Using both the logit model and a fuzzy-set analytical approaches based on a new official sample of 2700 privately-owned and 148 state-owned firms over the period of 2011 to 2013, the study add further evidence to growing methodological consideration regarding complexity theory. The results show a significant negative effect of corruption on firm innovation, additional, firm sale and education and market have a positive bearing on innovation activity. However, the government ownership firms have a negative and significant effect on innovation. The findings have important implication for theory, practitioners and policy-making and shed light on a new perspective to focus on the long run effect of corruption.

The management of the New Service Development (NSD) process remains a key research priority for service organizations. As a diverse mix of team members with different skills, perspectives and backgrounds participate in development teams and close collaboration is required among them, conflicts are likely to arise among team members. Different team members perceive conflict episodes in a different way and often embrace different conflict management behaviours and orientations (e.g. competing, avoiding) to deal with them. This study recognises NSD team as a complex system, through which individual members’ conflict management style choices enable team developmental dynamics, which sequentially lead to intragroup conflict resolution. Although a lot of work exists around the role of individual members’ conflict management styles, little research scrutiny is attracted on how teams solve intragroup conflicts and even limited empirical evidence is available regarding the linkages between individual and team factors can contribute to resolve intragroup conflicts. The present study taking under consideration the causal complexity, asymmetry and idiosyncratic nature of NSD conflict resolution, utilizes Complexity theory and leverages the advantages of fs/QCA in order to shed light on the NSD intragroup conflict resolution. Data was collected from employees in several service industries such as advertising, financial, insurance, consulting, IT services and telecommunications providers. The results confirm the major tenets of Complexity theory highlighting that any attempt to examine complex phenomena, such as NSD conflict resolution, as simple ones, based on symmetrical methodological approaches, may lead to simplistic and distorted explanations. In fact, the results demonstrate that there is not a ‘one fits all’ solution in order to solve NSD conflicts. Different facets for both the conflict-management styles and team dynamics act in various combinations in order to predict high scores in NSD conflict resolution.

PURPOSES: Nighttime driving is very different from daytime driving because drivers must obtain nighttime sight-distances based on road lights and headlights. Unfortunately, nighttime driving conditions in Korea are far from ideal due to poor lighting and an insufficient number of road lights and inadequate operation and maintenance of delineators. This study is conducted to develop new standards for nighttime road visibility based on experiments of driver perception for nighttime visibility conditions. METHODS : In the study, perception level and satisfaction of nighttime visibility were investigated. A total of 60 drivers participated, including 34 older drivers and 31 young drivers. To evaluate driver perceptions of nighttime road visibility, fuzzy set theory was used because the conventional analysis methods for driver perception are limited in effectiveness for considering the characteristics of perception which are subjective and vague, and are generally expressed in terms of linguistic terminologies rather than numerical parameters. RESULTS : This study found that levels of nighttime visibility, as perceived by drivers, are remarkably similar to their satisfactions in different nighttime driving conditions with a log-function relationship. Older drivers evaluated unambiguously degree of nighttime visibility but evaluations by young drivers regarding it were unclear. CONCLUSIONS : A minimum value of brightness on roads was established as YUX 30, based on final analyzed results. In other words, road lights should be installed and operated to obtain more than YUX 30 brightness for the safety and comfort of nighttime driving.
