Marathon Runners: A Fertile Market for “Green” Donations?
Stavros Triantafyllidis,Kyriaki Kaplanidou 글로벌지식마케팅경영학회 2021 Journal of Global Sport Management Vol.6 No.4
Marathon events are hosted annually by various communities around the United States. Within this context, marathon runners train and compete in various natural environments. Nature-based places can be primary training areas and often consist a large part of marathon events. Marathon runners, therefore, may care more about the quality of the nature they train in, as the environmental quality can connect to health benefits. The purpose of this study was to test how various types of marathon runner’s motivations influence their environmental concern and donation intentions toward green initiatives. Data was collected from marathon runners of a marathon event using a web-survey. In total, 103 marathon runners responded fully to the questionnaire. Findings indicated motivations related to self-esteem, health benefits, and environmental concern influences significantly and positive marathon runners’ donation intentions for green initiatives. Limitations are highlighted, as future research can explore further the conceptual model of this inquiry.

The bifurcation problem of thin walled structures in contact with rigid surfaces is formulated by adopting the multiple scales asymptotic technique. The general theory developed in this paper is very useful for the bifurcation analysis of waviness instabilities in the sheet metal forming. The formulation is presented in a full Lagrangian formulation. Through this general formulation, the bifurcation functional is derived within an error of O($(E^4)$) (E: shell's thickness parameter). This functional can be used in numerical solutions to sheet metal forming instability problem.

<B>Graphic Abstract</B> <P>Cracking good cracking: Mesoporous ZSM-5 zeolite catalysts (see TEM image) made by soft templating methods show higher gas–oil cracking activity and greatly enhanced product selectivity than conventional ZSM-5. The cracking of large hydrocarbons to gasoline and diesel fuel occurs in intracrystal mesopores, while the conversion of smaller molecules into feedstock olefins occurs in framework micropores. <img src='wiley_img/14337851-2009-48-41-ANIE200901551-content.gif' alt='wiley_img/14337851-2009-48-41-ANIE200901551-content'> </P>
