Concordance invariants and the Turaev genus

We show that the differences between various concordance invariants of knots, including Rasmussen's $s$-invariant and its generalizations $s_n$-invariants, give lower bounds to the Turaev genus of knots. Using the fact that our bounds are nontrivial for some quasi-alternating knots, we show the additivity of Turaev genus for a certain class of knots. This leads us to the first example of an infinite family of quasi-alternating knots with Turaev genus exactly $g$ for any fixed positive integer $g$, solving a question of Champanerkar-Kofman.Comment: 6 pages, 3 figures.

Transforming sport consumption: Exploring motivated sport fans innovativeness in the context of AR live sport streaming

Purpose This study delves into the psychological processes underlying sport fans' post-purchase innovativeness behaviour. This exploratory research aims to establish a theoretical framework that elucidates the formation of sport fans' word-of-mouth (WOM) behaviours, particularly emphasising the structural relationship between motivated consumer innovativeness and satisfaction in using AR live-streaming services. Design/methodology/approach Utilising an online survey and convenience sampling, the study garnered a total of 243 usable responses from three online baseball fan communities in South Korea. Confirmatory factor analysis was employed to assess the psychometric properties of the constructs. Subsequently, a structural equation model was used to probe the influence of motivated consumer innovativeness on WOM, with a particular focus on the mediating role of satisfaction. Findings Three dimensions of motivated sport fans innovativeness – functional, hedonic and cognitive – showed a positive association with WOM, partly mediated by satisfaction. In contrast, socially motivated sport fans innovativeness did not directly lead to WOM but influenced it solely through satisfaction. The full mediating role of satisfaction in the relationship between socially motivated fans innovativeness and WOM was found. Originality/value This research stands out as one of the scant studies exploring motivated sport fans innovativeness in the context of AR live sport streaming. The findings not only corroborate but also augment the extant literature by empirically confirming that three dimensions of motivated fans innovativeness, coupled with satisfaction, are pivotal antecedents to WOM intention

The effect of government-public relationships on residents’ support in mega sport events: A moderating effect of government crisis response

The study seeks to investigate the role of host governments’ policy public relations and crisis response strategies in shaping residents’ support for mega sport events. Specifically, the research focuses on the moderation effects of crisis response strategies on the relationships between the government-public relationships (GPR) dimensions (i.e., control mutuality, trust, and satisfaction) and residents’ support. The research targeted residents of Tokyo, a host city for the 2020 Olympic and Paralympic Games. Online surveys were disseminated via an international survey company between 23rd to 29th October 2020, obtaining 500 complete responses. Then, a two-step approach was utilised to ensure the tenability of the hypothesised model: CFA for testing the measurement model and SEM for testing the hypothetical relationships. There was a positive association between perceived control mutuality and satisfaction with residents’ support for the mega sport event. The study reaffirmed the importance of control mutuality and satisfaction as GPR indicators for residents’ support, introducing this concept into the mega sport event context. In addition, the relationship between control mutuality and residents’ support was moderated by their perception of the appropriateness of crisis response. Based on the results, theoretical and practical implications were presented

Does relationship quality matter in policy-making? The impact of government-public relationships and residents’ perceptions on their support towards a mega-sport event

Guided by the increase in social and political challenges faced by local governments in their efforts to host mega-sport events, this study attempts to shed light on the under-researched relationship quality between a local government and its residents. Enhancing the relationship quality and mutual understanding through two-way communication between the government and its residents has become more important than ever, with the host community considered a key stakeholder in the policy decision-making process, due to the development of online communication technologies. This research aims to identify the major determinants of residents’ support, using government public relationships and social exchange theory. Data collected through a survey of Tokyo residents (N = 406), where the Tokyo 2020 Olympic and Paralympic Games were hosted, are analysed using structural equation modelling. Results show that satisfaction with the government can considerably influence the perceived impacts of a mega-sport event and trust, while trust in the government is shown to be a robust predictor of residents’ support and a mediator to social exchange theory. Also, the importance of a mega-sport event’s perceived impacts on residents’ support is shown, further supporting social exchange theory. Through the findings and the integration of the two theories, this study illustrates the need for the government to focus on producing policies aiming to increase its public satisfaction and thus their trust in government using balanced symmetric communication, which in turn can raise residents’ support for a mega-sport event and help establish a mutually beneficial relationship between the government and its public

Building team brand equity through perceived CSR: the mediating role of dual identification

While involvement in CSR activities is common practice in today’s sporting world, there is a need to go beyond the activities themselves to explore how fans’ perceptions of CSR can affect customer-based brand equity and what role online-community and team identification can play in this relationship, which this study aims to explore. Data collected through an online survey of South Korean Samsung Lions baseball club fans (N=331), analysed through structural equation modelling, support the positive influence of perceived CSR on dual identification (team and online-community), and the impact of team identification on brand equity. Interestingly, CSR perception is shown to be an insignificant predictor of brand equity, influenced fully by team identification. This study suggests that promoting a sport team’s socially responsible image is important in terms of building both team and online community identification while developing team identification can be vital in increasing the value of the sport brand

Classification of thermal environment control indicators according to the thermal sensitivity of office occupants

The control that have the greatest influence on comfortable in the office occupants are the heating, ventilation, and air conditioning (HVAC) system operation and the thermal environment. However, comfortable HVAC operation is difficult in the office space characterized by a recommended standard thermal environment or a centralized HVAC system. To consider the occupant's thermal comfort to the greatest possible extent, must establish a method to quantify the variables related to the occupant’s thermal comfort. This study aims to group occupants in Thermal sensation vote (TSV) clusters and perform sensitivity analysis (SA) on the relationship between thermal environmental factors in an office building and each cluster’s TSV to establish the typology of the control indicators for each cluster. A total of 10 field experiments were conducted in the same office. This field study was carried out 2022. The indoor thermal environmental parameters, the subjective evaluation of the thermal comfort of the resident and the operation pattern of the heating system were monitored at the same time. A total of 4,200 datasets related to indoor thermal environmental parameters and a total of 1,680 datasets related to occupants’ thermal comfort were collected and analyzed. The results of this study show that people have different levels of adaptability and sensitivity to a given thermal environment. This study founded distinguishable similarities in their thermal sensation traits and grouped similar TSV values into five clusters that responded differently to the same thermal environment. Each cluster showed different TSV and Thermal comfort vote (TCV) patterns, which allowed us to classify the groups that had sensitive responses to the thermal environment and those that did not. This study was determined different control indicators and guidelines for the divided groups according to thermal sensitivity

From horizontal to vertical relationships: how online community identification fosters sport fans’ team identification and behavioural intentions

Purpose: With the remarkable advancements in information and communication technologies, comprehending online sport fan communities is being pushed further up in the agenda of sport teams worldwide. Based on social identity theory, the main purpose of this research paper is to test the mechanism of how horizontal relationships developed through online communities lead to vertical relationships such as team identification and behavioural intentions. Design/methodology/approach: Using a sample of online baseball fan community members in South Korea (N = 400) and employing structural equations modelling, the current research examined the structural relations among online community identification, team identification, behavioural intention and WOM intention while testing moderating effect of perceived authenticity. Findings: This study finds that online community identification has a significant positive impact on team-level consumer outcomes: team identification, behavioural intention and WOM intention. Team identification is verified as a significant determinant of both behavioural intention and WOM intention. Moreover, the partial mediating role of team identification in the relationships between online community identification and behavioural intentions are corroborated. Originality/value: The present study furnishes essential information for identifying the underlying mechanism of how fan-to-fan horizontal relationships cultivate team-to-fan vertical relationships in the context of the virtual fan community.</p

Public relations: the missing element in the eSport governance

Despite the enormous value public relations can yield to the eSport ecosystem in communicating and building sustainable relationships with various stakeholders, scant research emphasises the necessity for the adoption of a public relations approach in eSport. This commentary argues that the lack of a unified governance structure or an international governing body is the foremost hurdle of eSport, while a critical omission in the eSport governance discussion is how to build and sustain relationships among partners. By combining these two and viewing issues through the lens of public relations, we suggest that principles of good governance such as transparency, public communication and democratic processes, can be achieved in eSport by employing appropriate public relations strategies.</p
