Customer engagement (CE) is an emerging perspective that provides a holistic view of the ways in which customers’ interactive experiences with organizations create value for both the parties. Central to this, is the need to develop an understanding of why a customer would choose to invest their resources (cognitive, emotional, and behavioral) with an organization, to be able to better facilitate this engagement and properly value the outcomes from it. Sport, with its inherently strong interactions for both participants and fans, would seem an ideal setting to study CE. To date, however, the CE work in sport domains has largely followed established paths. Given CE’s potential to unify many disparate areas of sport research, this paper presents a comprehensive review of the CE work to date and highlights several ways sport can leverage and advance this work through both academic research and management practice.

Business intelligence (BI) technologies can help firms optimize revenue and expenses if acquired and deployed proficiently. In parallel, the sport industry’s shift toward digitization is being driven by an influx of new, technology-savvy owners and managers. It follows that owners who are business intelligence experts could make their sport organizations more profitable. This paper models 14 years of Major League Baseball data to explore the degree to which owners with business intelligence career experience affect their organization’s operating margin through (a) optimizing revenue and (b) enhancing cost efficiency. It further explores owners’ knowledge accrual as a moderator in this process. Results suggest the effect of business intelligence expertise on margins is positive, but small. Margin increases were attained by spending more efficiently on labor, not by generating more revenue. These mediating effects were moderated by knowledge accrual, such that a longer tenure increased the early-tenure advantages of BI career experience.

While the progress of women in the sport industry has become more visible, there is still significant gender inequity. Extending the sport organizational literature, we argue that the unpaid, invisible, and emotional labor of women, especially those holding diverse social identities, is significantly contributing to gender inequity at the organizational level. In broader sport research, the micro, everyday experiences of women stakeholders and the connection to macro societal structures and ideologies have provided foundational insight to build upon. However, there is a need for research to focus on the meso-level organizational practices, policies, designs, structures, and culture to create real change. Therefore, we present a conceptual paper, focused on a meso-level analysis and the invisible labors that women stakeholders engage in, to extend existing work and provide a pathway for further investigation into gender inequity in sport.

Despite consistent interest in sport brands and the multitude of brands in the sport ecosystem, extant knowledge remains fragmented and unstructured. The purpose of this study is to integrate and synthesize extant sport brand research, appraise the current state of knowledge, and suggest future research directions. Following structured literature review guidelines, we coded 179 peer-reviewed articles published in four leading sport management journals between 2000 and 2020. Results reveal increased publications in sport brand research within the four examined journals, as well as opportunities to increase theoretical and methodological rigor. Based on the mapping and critical review of extant literature, we introduce the Sport Brand Ecosystem and Environment and discuss two distinct and complementary areas related to theory and research designs and topical domains to address existent concerns and guide future research directions.

Sport organizations are developing family-friendly spectator initiatives to boost engagement and sales to parents and children. While the number of women sport fans continues to grow, research has yet to explore how women, as mothers and fans, experience fandom. Informed by a maternal geography framework, this study explores women’s understanding of what does or does not make game-day experiences family-friendly by presenting the accounts of 15 women from North America and Australia who are sport fans and mothers. Interpretive phenomenological analysis is utilized to investigate how mothering as a spatially informed care practice shapes the perspectives of what constitutes a family-friendly sport spectating experience. Findings identify key components of the physical, structural, and social environments of women’s experiences of family-friendly sport fandom, as well as exposing that what is presumed to be family-friendly is not the same as mother-friendly.

Sport team licensed merchandise plays an important role in sport fan experiences. Existing work has explored how consumers perceive these items, motivation and consumption habits, and intent to purchase. Extending upon the performative sport fandom framework, this study explores the marketing messages of sport fan merchandise, and the resulting implied gendered and fan performances. Employing a multimodal critical discourse analysis, we analyzed the top 20 T-shirts for men and women for five National College Athletic Association institutions on their official ecommerce sites. By examining the text descriptions, visual images, and messages perceived when combining text and visuals, we found that the marketing messages of clothing items rely heavily on traditional discourses of femininity and masculinity, placing gender performances as more relevant to fan performances for women. Atypical designs suggest alternative gender and fan performances but continue to indicate that gender identity is central to clothing appearance and messaging to consumers.
运动队授权商品在体育迷体验中扮演着重要的角色。现有的工作已经探索了消费者如何看待这些物品，动机和消费习惯，以及购买意图。在表演性体育迷框架的基础上，本研究探讨了体育迷商品的营销信息，以及由此产生的隐含性别和球迷表演。采用多模态批评话语分析，我们分析了五家美国大学体育协会(National College Athletic Association)官方电子商务网站上排名前20的男女t恤。通过研究文本描述、视觉图像以及文本和视觉结合时所感知到的信息，我们发现服装的营销信息严重依赖于传统的女性气质和男性气质话语，将性别表演与女性粉丝的表演更相关。非典型设计暗示了另类性别和粉丝表演，但继续表明性别认同是服装外观和向消费者传达信息的核心。

With few exceptions, researchers have seldom explored the experiences of any female sport fan who may be identified as a member of a racial minority. Given related calls for further research, an examination into the lived experiences of ice hockey fans who identify as Black and female was undertaken. Interviews with 18 such fans revealed that the sport and its fandom were akin to ‘White spaces’: therein, participants were keenly aware of their minoritized place; subject to racial and gender stereotyping and discrimination; and prone to experiencing exclusion and trepidation. Conversely, interactions with the Black Girl Hockey Club, an organization devoted to making ice hockey more diverse and accessible, provoked feelings of belongingness and validation; and afforded a means through which interviewees could deepen their engagement with the sport. The research participants’ lived experiences ultimately point to the need for organizations and managers to construct more inclusive spaces.
除了少数例外，研究人员很少探索任何可能被认定为少数种族成员的女性体育迷的经历。考虑到需要进一步研究的相关呼吁，研究人员对黑人和女性冰球球迷的生活经历进行了调查。对18位这样的粉丝的采访显示，这项运动及其粉丝圈类似于“空白地带”:在那里，参与者敏锐地意识到自己的少数群体地位;受到种族和性别陈规定型观念和歧视;而且容易受到排斥和恐惧。相反，与黑人女孩冰球俱乐部(Black Girl Hockey Club)的互动激发了归属感和认同感，该组织致力于让冰球变得更加多样化和大众化;并提供了一种方法，通过这种方法，受访者可以加深他们对这项运动的参与。研究参与者的生活经历最终指向组织和管理者需要构建更具包容性的空间。

Athletes may be especially primed to become referees; yet, we do not know what former athletes think about this career choice. To address the worldwide referee shortage, it is important to better understand athletes’ perceptions of refereeing. From a Career Contingency Model framework, it is evident athletes’ perception would influence their decision to consider refereeing. This study’s aim was to examine athletes’ perceptions of the refereeing environment (RQ1) and identify referee recruitment barriers (RQ2). Utilizing a descriptive phenomenological approach, 23 current and former athletes took part in semistructured interviews based on their lived experience as an athlete. The participants identified the officiating environment as a high-stress environment with financial instability, while time and lack of knowledge and support were identified as recruitment barriers. The results contributed to the burgeoning line of research attempting to address the global referee shortage and provide both theoretical and practical implications for sport managers.

Scholars have begun to explore the interplay between the multiple identities within a sport fan’s salience hierarchy, noting fandom may compete with other central roles. Researchers have also recently emphasized well-being outcomes for fans, with increasing focus on physical health. Though sport consumer behavior and health consciousness have concurrently emerged, the social psychological connection between the two is unclear. Thus, we aim to clarify this relationship. We leverage an emerging quantitative approach: polynomial regression and response surface methodology. Our findings indicate individuals who value both fandom and health consciousness (i.e., demonstrate high fan identity and health consciousness congruence) experience identity conflict, with men reporting higher levels of identity conflict than women. Thus, we contribute to literature on the potential negative sides (or challenges) of fan identity. The food and sedentarism common to fan culture appear to prompt psychological turmoil for health-conscious individuals. Fan identity may naturally integrate with other social roles, yet our results indicate fandom and health consciousness are often viewed in conflict.
