Purpose The primary purpose of this study is to show and guide how to construct a large variety of behaviors in systems dynamic for sport science. Methods By applying a simple algorithm to networked agents, which could, conceivably, offer a straightforward way out of the complexity, computational mechanism which along with its dynamics (payoff, failure, and strategy) involved. Results The model starts with the probability that systemic risk potential such as failure spreads. Even in a very random structure commonly used in sports field, propagation of the potential is guaranteed by an arbitrary network property of a set of elements. Despite the intensive systemic potential, the opposite type of potential like absence of failure could also be driven when there has been a strong investment in protection through a heuristically evolved protection level. Conclusion The implementation still needs to be polished against what happens in the real sports world, but in general, applied conceptual principle and methodological techniques behind the network-agent based mechanisms could be useful for researchers those who need to use systemes dynamic to guard in sport science.
PURPOSE This study aimed to verify the differences in anticipated regret and gambling discontinuance intent based on the fear appeal type and source similarity in different types of horse-racing gamblers. METHODS Using convenience sampling, 172 responses were collected from horse-racing participants who bought horseracing tickets within the last 6 months. After eliminating 30 insincere responses, descriptive, correlation, reliability, and two-way multivariate covariance analyses were conducted using SPSS Ver. 26.0. RESULTS Anticipated regret and discontinuance intent were higher under fear appeal using social compared with financial risk. Compared to recreational gamblers, problem gamblers had higher anticipated regret and discontinuance intent under fear appeal using social compared with financial risk. There were no differential impacts of source similarity on anticipated regret and discontinuance intent in both types of gambler. CONCLUSIONS Practitioners in charge of conducting messaging campaign to prevent addiction to horse-racing gambling may cause problem gamblers to expect regret and quit gambling by delivering preventive messages with relatively unfamiliar risks such as social risks, rather than familiar risks such as financial ones.
