With the club industry comprising of different types of clubs, a more in-depth analysis separating clubs with and without golf operations would be beneficial. Financial performance can be summarized via financial ratios. This study surveyed 115 clubs regarding their financial performance and calculated 24 financial ratios for 2014. The median profit margin of all clubs was at 1.65%. Clubs with golf operations reported a median profit margin at 1.73%, doubling that of the nongolf operations at 0.83%. T-tests using means of financial ratios showed a statistically significantly difference in only the food inventory turnover by days. 相似文献

Outdoor recreation provides a range of health and wellbeing benefits and facilitates engagement with natural environments. We explore older people's participation in outdoor recreation throughout their lives to examine how past experiences shape engagement later in life. A qualitative life history approach, consisting of semi-structured interviews and a focus group in three place-specific (urban, rural, and small town coastal) case studies in Scotland, was adopted. Thematic analysis revealed ways in which childhood experiences shaped adult engagement and highlighted life course transitions where behaviour change was most pronounced. Place and gender were considered as factors which may affect responses. Participants identified the points of getting married, becoming a parent, children entering adolescence, retirement, the onset of disabilities or ill health, and the death of others as “moments of change” in the extent and/or form of their outdoor recreation. The findings highlight potential for targeted interventions to promote outdoor recreation throughout life. 相似文献

In an initial coin offering (ICO), new ventures raise capital by selling tokens to a crowd of investors. Often, this token is a cryptocurrency, a digital medium of value exchange based on the distributed ledger technology. Both the number of ICOs and the amount of capital raised have exploded since 2017. Despite attracting significant attention from ventures, investors, and policy makers, little is known about the dynamics of ICOs. This initial study therefore assesses the determinants of the amount raised in 423 ICOs. Drawing on signaling theory, the study explores the role of signaling ventures' technological capabilities in ICOs. The results show that technical white papers and high-quality source codes increase the amount raised, while patents are not associated with increased amounts of funding. Exploring further determinants of the amount raised, the results indicate that some of the underlying mechanisms in ICOs resemble those found in prior research into entrepreneurial finance, while others are unique to the ICO context. The study's implications are multifold and discussed in detail. Importantly, the results enable investors to more accurately understand crucial determinants of the amount raised (e.g., technical white papers, source code quality, token supply, Ethereum-standard). This reduces the considerable uncertainty that investors face when investing in ICOs and enables more informed decision-making. 相似文献

基础设施公募RE I Ts是改善城镇化投融资机制、盘活基础设施存量资金、防范化解城镇化债务风险的重要创新。但是,现行制度安排对REITs的税收中性、法律框架、市场流动性等中长期发展因素的考虑存在不足,这可能带来摊薄REITs产品投资收益、加大治理与监管成本、制约市场可持续发展等问题,亦对城镇化区域均衡发展产生不确定影响。建议在结合国外经验和中国国情的基础上,加快推动REITs税收优惠政策落地,研究制定“REITs管理条例”等法律体系,完善二级市场建设和流动性培育,优化基础设施公募REITs支持新型城镇化的空间布局。 相似文献

高校思想政治理论课是大学生思想政治教育的主渠道。职业素养教育是高职院校人才培养体系中的特色环节,也是高职院校进行大学生素质教育的重要阵地。高职院校思想政治理论课与职业素养教育实现有机融合,可以有效调动各种资源形成教育合力,有利于高职院校构建大思政工作格局。高职院校可以从做好顶层设计、整合人才队伍、融入教育载体、互鉴教育方式、规范考核评价五个方面加强思想政治理论课与职业素养教育的有机融合,形成协同育人效果。 相似文献

以往对公募基金羊群行为的研究聚焦于宏观层面不同基金公司所持股票组合的相似性,而该研究则从微观视角研究了羊群行为:(1)单个公募基金公司所管理的多个基金相互模仿投资策略所呈现的羊群行为;(2)基金经理的交易行为所呈现的羊群行为。使用LSV模型测量2010—2019年多个公募基金公司内部的羊群行为,发现同个公募基金公司所管理的多个不同基金存在相互模仿投资策略的羊群行为,程度高于宏观层面不同公募基金之间相互模仿的羊群行为。此外,还发现基金经理的买入卖出交易行为存在羊群效应。研究从新的视角检验了微观层面的羊群行为,为基金公司加强内部管理、避免基金经理跟风投资造成风险聚集提供参考。 相似文献

ABSTRACTThis study discusses how to apply counseling-learning (CL) principles to a particular e-learning solution for teaching a tourism-related subject via a massive open online course (MOOC). Several effective caring patterns in achieving learning-related goals and being part of a community according to the CL principles are presented and discussed using the MOOC “eTourism: Communication Perspectives” as a case study. The study underlines how the MOOC platform can act as a place for contents enjoinment and active learning. Moreover, the active role of social media for increasing the engagement of learners in the proposed activities and for developing a sense of the community is identified. In particular, Facebook and Twitter can act as places for community building and informal social interactions among learners that last beyond the completion of the course, which in turn can be a valid aid for continuing the relationships among instructors/learners and learners/learners, and for reaching new ones. 相似文献

股权再融资往往意味着企业存在大量的融资需求,而实践中普遍存在的股权再融资后立即现金分红的现象有悖于募集资金的优序使用原则。基于此,本文从管理层自利视角出发,在对企业股权再融资后现金分红的行为偏好检验的基础上,进一步选取管理层薪酬增长率和企业股权质押活动作为管理层自利程度的代理变量,探索企业股权再融资后现金分红倾向的边界条件,为该行为背后的代理动机提供证明。基于2007~2017年所有A股上市公司样本,研究发现,企业的确存在股权再融资后立即现金分红的行为倾向;而较低的管理层薪酬增长率和企业股权质押活动会加剧企业股权融资对现金分红的促进作用。进一步研究发现,企业股权再融资活动会给现金分红带来消极的市场反应。上述研究结果表明,管理层自利是股权再融资的重要推动因素,而这一行为会给企业利益造成损害。 相似文献

论文对近历史记载以来黄河下游河段河道变迁历史进行总结概括并重新绘制了黄河下游河道变迁示意图。黄河下游河段按流向分为北、东、南三个方向。北流河道相对分散,形成了一系列三角洲沉积,有的已被沿岸河流带来的沉积物覆盖;东流河道在入海口处河道变迁频繁,形成了规模较大的三角洲并持续至今。南流河道在摆动起始有多股漫流,经由淮河水系扩散,至苏北一带汇成一股由苏北汇入黄海并在苏北形成了规模较大的三角洲。结合相关研究成果,分析黄河河口沉积环境发现:黄河入海泥沙堆积有极高的沉积速率,在沉积年份每年可沉积数十厘米至数米,可以快速向海淤进形成三角洲,而黄河行水期结束后,则无沉积甚至被侵蚀。研究结果表明,北至海河、南到淮河的大范围内沉积环境的塑造均与黄河有关,黄河与下游的滦河、小清河、弥河、潍河、淮河、射阳河等相互影响,共同塑造了华北平原的沉积格局。 相似文献
