Women’s football struggles to build a solid platform in terms of fan interest. However, while an increase in gate receipts can help assist its long-term sustainability, there is limited evidence in the academic literature on the factors influencing spectator demand in women’s football. The authors investigate determinants of stadium attendance for UEFA Women's Champions League (UWCL) matches. Using regression models deployed on 554 UWCL games played between 2009/10 and 2017/18, the authors examine contextual and sport-related variables as the main predictors of stadium attendance. Findings show that there is no continuous growth of attendance over the period examined, and highlight that spectators’ interest is positively associated with five factors: stage of the competition, uncertainty of match outcome, competitive intensity, away club’s reputation and weather conditions. Football governing bodies should put in place initiatives to ensure match outcome uncertainty is maintained as this represents a key determinant to maximise stadium attendance. Based on the specific context of European women’s football, recommendations to foster its development are discussed. These include incentivising investment into the elite women’s game and designing sport policies to encourage participation at grassroots levels. 相似文献

Team identification and sports fandom as predictors of fan aggression: The moderating role of ageing
《Sport Management Review》2019,22(2):194-208
In the current study, the explored the moderating role of ageing in the relationship between team identification/fandom and fan aggression. The authors used an online panel-based survey that offered access to a realworld population of sports fans. Participants were 740 fans of Israeli professional basketball. Results from structural equation modelling demonstrated that older fans reported higher levels of mere sports fandom and lower levels of self-reported aggression and acceptance of aggression. Moreover, age moderated the relationships between team identification (or fandom) and self-reported aggression, such that team identification (or fandom) was more strongly associated with selfreported fan aggression among younger fans than among older fans. The moderating role of age in the relationships between team identification (or fandom) and perceptions of appropriateness of aggression was not supported. The findings contribute to our theoretical understanding of the role of ageing in the relationship between fan identification and fan aggression. Based on these findings, the authors assert that managers might particularly benefit from leveraging the potential, but often neglected, segment of senior fans, since older fans can play a key role in reducing the level of aggression during competitive sports events. Suggestions for future research are also discussed. 相似文献

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history. 相似文献

《四时田园杂兴》是范成大退居石湖创作的一组诗歌,自问世以来颇受瞩目,但至今仍少有人关注其特殊的结构形式。作者选择这一特殊结构形式有其特殊的寓意:纪念伴随其出生以来历久弥深的国耻。这一选择的驱动力来自我国的文化传统、作者的经历及对诗歌风格的好尚。 相似文献

不等式的证明在高等数学通用教材中遇到的较多,学生对它的处理往往无从下手,主要是因为由条件向结论过渡的解题方向不易确定,但是高等数学中不等式的证明还是有一些规律可循的。本文就不等式的证明归纳出了证明方法和基本思路。 相似文献
