The research aimed to estimate the economic-recreational value of Yadegar Emam Stadium in Tabriz from the spectators' perspective using the contingent valuation approach. A sample size of 415 football fans attending the matches was studied through simple random sampling. A researcher-made questionnaire was used, and Logit and Probit rank-based methods with Stata software were employed for data analysis. The findings revealed that factors including income, proposed price, watching matches on television, satisfaction with stadium facilities, and enjoyment from watching games, positively influenced the willingness to pay. Conversely, variables including education level, age, and marital status had a negative correlation with willingness to pay. These results highlight the significant economic and recreational value held by Yadegar Emam Stadium. The estimation data can aid in managerial decision-making, sports development, and planning, leading to economic and social benefits, and promoting the football industry.

Today, using new technologies is considered a vital factor in the sports tourism area. Tourist destinations try to use these technologies to create a competitive advantage to be a leader in this area. The use of these technologies brings lots of advantages. This research aims to identify the consequences of using new technologies in sports tourism. The research method is mixed with a sequential exploratory approach. In the first phase, the main indicators and components are identified using the online focus group research method, then in order to confirm them, a quantitative survey method was used. The data collection tools are semi-structured interviews collected from two focus groups including academic and executive participants related to the fields of sports management, sports tourism, and information technology. According to the research findings, 67 primary codes, 27 open codes, 13 axial codes, and 4 selective categories were extracted. In the quantitative phase of the research, all the values ​​related to the components and indicators were confirmed.  From the results of the present research, we can point out the benefits such as "smart health, smart sports tourism, green technologies, sustainable development (healthy and sustainable environment, dynamic and healthy economy, etc.), smart and sustainable sports tourism destinations" that were found to be the main advantages of using new technologies in sports tourism.

Schadenfreude has been defined as the enjoyment of others’ misery; a kind of happiness from malice, which one acquires when one learns that others are lucky or experiencing a setback. The purpose of this study was to analyze the experiences of Sulaymaniyah football team fans regarding the theory of happiness from the Erbil team's discomfort in Iraq. An interview was conducted with the fans who had lived experiences (N = 18) and the data were analyzed using thematic analysis. The findings showed that several factors affect schadenfreude, such as political and governmental problems, managerial weaknesses of responsible people, past problems, and discrimination between teams. The findings extend the theory of social identity theory. According to the results, the managers of the teams and the officials of the Kurdistan Region in Iraq can provide the ground for reducing the happiness of the opponent's team with proper management and non-partisanship of the teams. Research in the field of schadenfreude can reduce the problems of advocacy and the wrong decisions of managers and officials and contribute to equality in this field.

Background: Alzheimer’s disease (AD), the most prevalent neurodegenerative disorder, is characterized by amyloid-beta (Aβ) plaque accumulation, neurofibrillary tangles, neuronal death, inflammation, and oxidative stress.Aim: We investigated the effects of treadmill exercise and intranasal insulin on spatial memory, blood glucose level, and Physical growth indicators including weight, head circumference, and tail length.Materials and Methods: Seventy-two male Wistar rats, aged 8 weeks were into 9 gtoups at random (control, Sham, Aβ, Aβ + EX, Aβ +PINS, Aβ + INST, Aβ + EX + PINS, Aβ + EX + INST, and Aβ + EX + PINS + INST). We discovered that rats receiving Aβ25-35 had impaired spatial memory, which was associated with weight loss, brain growth retardation, Tail Length, and elevated blood glucose levels. Data from each trial was statistically analyzed using IBM SPSSStatistics 22 software, Two-way ANOVA, and post-hoc analysis Tukey test. The cut-off for statistical significance was P≤0.05.Results: Our results show that the improvement of spatial memory due to the improvement of metabolism and growth indicators can be affected by pretreatment exercise and intranasal insulin. Also, exercise training and intranasal insulin improved spatial memory and prevented brain growth retardation, increased blood glucose, weight loss, and tail length in animals treated with Aβ25-35.Conclusion: Exercise can amplify the positive benefits of intranasal insulin treatment on memory. The results of our research showed that exercise and insulin can prevent brain growth retardation and prevent spatial memory disorders by improving glucose metabolismy.

This study investigates what effect stadium elevation has on the win-loss performance of home teams in major college football. Despite extensive research on factors that influence home-field advantage in sports, the potential impact of altitude on the performance of college football teams has not been thoroughly explored. Therefore, the purpose of this study is to compare the records of institutions playing home games at the highest elevation stadiums with national averages. In contrast to its effect on sports like international soccer or running, results indicate that teams playing in stadiums at higher elevations have no significant difference in win-loss percentage than the national average as findings suggest that altitude does not play a significant role in the performance of FBS teams. Unlike soccer teams playing in high-altitude cities or runners training in the mountains prior to racing at lower levels, this study concludes that playing in stadiums located at higher elevations does not significantly impact win-loss percentage of college football teams. This study contributes to the understanding of the factors that influence home-field advantage in college football and the limited impact of altitude on college football.

This study deals with the effect of structural empowerment on professional commitment of male referees with the mediating role of job characteristics in Iranian football premier League. Datacollected using a self-report survey. In addition to demographic items, the survey comprised 46 items measuring structural empowerment, professional commitment and, job characteristics. Experts in sports management and football refereeing confirmed the face and content validity of the questionnaire. 130 valid questionnaires completed by referees in the Persian Gulf Pro League in Iran. Structural equation modeling, confirmatory factor analysis and, path analysis were conducted for data analysis by using PLS Smart software. The effects of structural empowerment on professional commitment (T-Value= 2.27 and ß= -0. 18) and job characteristics on professional commitment (T-Value = 8.93 and ß = 0.63) were both positive and significant. The effect of structural empowerment on job characteristics (T-Value = 4.94 and ß = 0.43) was positive and significant. Referee’s Job characteristics had a significant mediating role in the relationship between structural empowerment and their professional commitment (T-Value= 4.15, ß= 0.27). The findings can provide critical insights for sport managers be more efficient in the field of football refereeing.
