The aim of this study was to analyze the dispersion and evaluate the level of access to sports uses based on data from Tehran

The method of the present research was applied and was descriptive-analytical in terms of monitoring variables and data analysis. ARC GIS software was used for data analysis. Evaluation of distribution and distribution of sports spaces was done in two ways: network analysis method based on access to sports spaces and focal spatial statistics analysis method based on the size of sports spaces

All results showed that District 10 to 86 percent, the highest level of sport's coverage area and then the 6, 14, 8 and 3 respectively with 84, 80, 79, and 77 percent in the next category were located. Regions 21 and 22 were not well distributed despite high per capita sports area with minimum coverage level of service sports space. After this, regions 18, 5 and 4, respectively 35, 43 and 57 percent of the least important loss of service. In the region of 21 only 43 percent of the residential land use sports spaces located in the service area. And then 22 and 5 least favorite areas in the distribution of its sports spaces. Regions 8 with 96% and District 10 to 99% have the highest proportion of residential land use in the coverage of sports spaces.

According to the results of this study, having a high per capita sport does not necessarily require more use and more access. In fact, the main sports facilities in Tehran are located in areas where the opportunity to visit them is relatively small.

With the advent of social media, social networks have also emerged as one of the newest management topics. Social networks play an essential role in promoting and circulating information in major sporting events. Concerning this, the purpose of this study is to investigate and compare how to promote the Rio 2016 and Tokyo 2020 Olympic Games on social media. The social network analysis approach used to examine the Games Promotion Network, for which all the tweets of the official page of the two Olympics extracted from Twitter. 2256 tweets obtained from the official page of the Rio Olympics and 3287 tweets from the official page of the Tokyo Olympics, which finally included 436 tweets from the Rio and 905 tweets from Tokyo. Findings showed that athletes were more numerous in both Olympics than other stakeholders regarding the number of actors in the network. At the same time, the communication weight of international sports organizations has been greater than that of other stakeholders. The present study showed that it is impossible to promote a sporting event on social media without employing multiple stakeholders. However, depending on the purpose of the sport and organizations, their pattern for brand or event promotion can be unique.

Scientometrics is one of the most common methods for scientific evaluations. The use of network analysis approach has been proposed in recent years as a suitable method for visualizing the co-word and co-author networks. The purpose of this study was a network-based analysis of a collection of articles published in the Journal of Applied Research in Sports Management since 2012 (384 articles). Published articles were examined from various aspects such as co-authors network, co-word network, and semantic network of articles. In this study, a proposed method for extracting and preprocessing the data required to illustrate different networks of articles and analyze them was proposed. PHP language was used for crawling and data processing and Python language and Gephi 0.9.2 software were used for network analysis and visualization of different networks. The results of co-word analysis show that in published articles, topics such as education, marketing, and organizational issues in the field of sports management are addressed more than other fields. Also, the clustering of the co-author network showed that the authors of the articles were more inclined to form small scientific groups in the form of universities or research institutes of their respective organizations. The presentation of the thematic map of the articles makes the researchers more aware of the status of the researches and also discovers the thematic gaps of the scientific researches.

The occurrence of corruption in sports is not a new phenomenon. However, in recent years, corruption in sports has taken on a complex and multifaceted form. It is no longer acceptable to consider isolated individuals or limited organizations as the main perpetrators of corrupt activities, because corruption has found a systemic character. And corrupt behaviors are usually carried out through a network that helps to hide the path of corruption. The purpose of this study is to analyze network corruption in sports. The research population is 18 university professors who have a history of research and study in the field of corruption. The factors of this research have been identified by reviewing the theoretical literature and research background (12 indicators). Multi-criteria decision making method including Fuzzy Delphi was used to analyze the data. Based on the findings of the present study, The highest consensus of experts on network corruption was assigned to the index of "diversity of skills and expertise of members" and the lowest was assigned to the criterion of "monopoly".

The purpose of this study is to analyze the status of studies conducted in the field of sports media in the international arena. The statistical population of the present study is all articles of sport media including 1360 ones indexed in the ISI database since 1983 to 2016, which have been analyzed using Scientometrics and network analysis software. The analysis was done on the identification of quantitive nature of studies by time, superisr journals in terms of number of articles, geographical distribution of relevant studies, the collaberative network of countries and the most frequent keywords used in title, abstract and per terms. The results showed that from 1983 to 2016, the number of research conducted in the field of sports media has grown relative, from 9 papers in 1983 to 92 papers in 2016. MEDICINE AND SCIENCE IN SPORTS AND EXERCISE magazine published 133 articles with the largest share in sport media. The United States, 670 articles and 49% of published articles, has the largest share of sports media coverage. The words "sport", "medium", and "performance", with 138, 129, and 124, are the most frequent in the title and abstract of the published articles, and the keywords of rehabilitation, community and internet are the most frequent words in the keywords espectively of these articles.
