The Relationship Between Basic Needs Satisfaction, Self-determined Motivation, and Burnout in Korean Esports Players.

This article aims to understand the relationship between basic needs satisfaction, self-determined motivation, and burnout in esports players. To achieve this, we investigate three research hypotheses: (1) The three dimensions of basic needs satisfaction have a positive effect on the self-determined motivation of esports players, (2) The self-determined motivation of esports players has a negative effect on their burnout, and (3) All three dimensions of basic needs satisfaction affect esports player's burnout, indirectly via self-determined motivation. Data were collected through an online questionnaire (n = 608) administered to Korean esports players who play online games as a leisure activity. Results indicate that player competence has a negative relationship with self-determined motivation, suggesting that Korean players do not associate increased levels of competence with their intrinsic motivation. The results show that intrinsic motivation is negatively associated with burnout, particularly exhaustion and reduced sense of accomplishment. It should be noted that Korean players' high level of competence can result in reduced levels of self-determined motivation, which can lead them to burnout. This should be addressed by the industry, practitioners, and researchers considering the cultural context and the relationship between the factors, which will contribute to the sustainable growth and prosperity of the esports.

Knowledge management in sport mega-events: A systematic literature review.

Introduction: The aim of this study was to conduct a systematic review to describe and explore the current state-of-the-art of sport mega-event knowledge management research. Methods: Following the PRISMA protocol, the authors conducted a systematic search of academic and gray literature in sport, social sciences, and humanities databases. From the initial 1,751 studies reviewed, 16 met the inclusion criteria. Findings: In these studies, knowledge management in sport mega-events was mainly researched in the context of the Olympic Games. Compared with other events, the Olympic Games built a more formal knowledge management programme, which may explain why it attracted more attention. Discussion: Most of the studies highlighted the importance of tacit knowledge and individuals, as well as the needs of different stakeholder groups. Findings showed that social, cultural, political, and historical differences between hosts weaken the effect of knowledge management. Many of the published empirical studies are descriptive investigations and lack support of related theories or conceptual frameworks. The impacts of knowledge management process on the host regions and knowledge transfer between events and local stakeholders have been little explored.

Sport Mega-Events and Displacement of Host Community Residents: A Systematic Review.

The aim of this study was to conduct a systematic literature review to understand how empirical data have informed the knowledge about the relationship between hosting sport mega-events and displacement of host community residents. Following the PRISMA protocol, we conducted a search of academic and gray literature in sport, social sciences, and humanities databases. We excluded conceptual papers, conference abstracts, and works that discuss urban transformation or displacement but are not related to sport events. We also excluded works that associate sport mega-events with urban transformations but are not related to resident displacement. From the initial 2,372 works reviewed, 22 met the inclusion criteria. In empirical studies, displacement of residents has been studied exclusively in the context of the Olympic Games, since Seoul 1988, but with a higher frequency in most recent Games (Beijing, London, and Rio). The gigantism and the sense of urgency created by the Olympic Games may explain why this event has been frequently associated with resident displacement. Findings showed that residents suffered either direct, forced evictions or indirect displacements. The selected studies show a contradiction between the discourse of sport mega-events guardians for supporting the United Nations Sustainable Goals (SDG) and the practice of human rights within host cities of such events.

Drinking water with red beetroot food color antagonizes esophageal carcinogenesis in N-nitrosomethylbenzylamine-treated rats.

This study was undertaken to determine if the oral consumption of red beetroot food color would result in an inhibition of N-nitrosomethylbenzylamine (NMBA)-induced tumors in the rat esophagus. Rats were treated with NMBA and given either regular water ad libitum or water containing 78 microg/mL commercial red beetroot dye, E162. The number of NMBA-induced esophageal papillomas was reduced by 45% (P < .001) in animals that received the food color compared to controls. The treatment also resulted in reduced rates of cell proliferation in both precancerous esophageal lesions and in papillomas of NMBA-treated rats, as measured by immunohistochemical staining of Ki-67 in esophageal tissue specimens. The effects of beetroot food color on angiogenesis (microvessel density by CD34 immunostaining), inflammation (by CD45 immunostaining), and apoptosis (by terminal deoxynucleotidyl transferase dUTP nick end-labeling staining) in esophageal tissue specimens were also determined. Compared to rats treated with NMBA only, the levels of angiogenesis and inflammation in the beetroot color-consuming animals were reduced, and the apoptotic rate was increased. Thus, the mechanism(s) of chemoprevention by the active constituents of red beetroot color include reducing cell proliferation, angiogenesis, and inflammation and stimulating apoptosis. Importantly, consumption of the dye in the drinking water for a period of 35 weeks did not appear to induce any overt toxicity. Based on the fact that red beetroot color contains betanins, which have strong antioxidant activity, it is postulated that these effects are mediated through inhibition of oxygen radical-induced signal transduction. However, the sum of constituents of E162 has not been determined, and other components with other mechanisms may also be involved in antagonizing cancer development.
