2016  Social Network Analysis of the FIFA 2014 World Cup: Quantification of Games Won by Germany  単独  2016/04/09 
International Network for Social Network Analysis  , XXXVI International Sunbelt Social Network Conference Presentation and Poster Abstract  , INSNA  , 211-212   

概要(Abstract) In a soccer game, players pass a ball to each other to score a goal. By entering the number of times player i passes the ball to player j into the (i, j) element of an adjacency matrix, we can analyze the game with social network analysis (SNA). In this presentation, we examine how the difference between a one-sided game and a close game can be quantified using SNA. The presenter will cite games from the FIFA 2014 World Cup, when Germany was the champion, as examples. The focus will be on four games in the second stage: Germany vs. Algeria (Round of 16), 2-1; France vs. Germany (Quarter-Finals), 0-1; Brazil vs. Germany (Semi-Finals), 1-7; and Germany vs. Argentina (Final), 1-0.

2015  Applying Actor-Network Theory to Engineering Ethics: the Challenger Case  未設定  2015/11/14 
Society for Social Studies of Science 2015  , Society for Social Studies of Science 2015 Abstracts   

概要(Abstract) Today, many STS scholars are interested in how STS can contribute to engineering ethics research and education. Engineering ethics is professional ethics for engineers, and has been studied mainly by moral philosophers. Now, however, increasing number of STS researchers are focusing on social responsibility of engineers. The purpose of this study is to show how actor-network theory (ANT) within STS can be used to realize fruitful engineering ethics. First, I will survey the preceding studies that applied STS approaches to ethical research and education in engineering. Second, I will review ANT, focusing on the concept of translation. I will suggest that the methodology of ANT should be complemented by an ethical point of view. Third, I will survey the preceding studies that sought to introduce an ethical point of view to ANT. Fourth, I will discuss how we can use ANT method with an ethical point of view in engineering ethics. Fifth, based on an ethical ANT approach, I will introduce the case study of the Challenger space shuttle accident in 1986 with the assistance of Vaughan’s STS study on the disaster. This case is one of the most important ones in engineering ethics, and my analysis of it will provide a new interpretation of the disaster compared with its traditional interpretation within engineering ethics. Finally, I will provide a summary of my study and suggest that more ANT-based research in case studies will provide a new perspective both for engineering ethics and STS.

2015  Application of Social Network Analysis to FIFA 2014 World Cup Soccer Games: Quantification of the Strength of Germany as the Champion  未設定  2015/05/24 
XXXV Sunbelt Conference of the International Network for Social Network Analysis  , Sunbelt XXXV International Sunbelt Social Network ABSTRACTS  , 277   

概要(Abstract) In a soccer game, players pass a ball each other to score a goal. By entering the number of times player i passes the ball to player j into the (i, j) element of an adjacency matrix, we can analyze the game with social network analysis (SNA). The research question in this presentation is how the strength of a winner of a soccer game can be quantified using SNA. The presenter will cite games from the FIFA 2014 World Cup as examples. Germany was the champion of the World Cup. The presenter will focus on 4 games of Germany in the 2nd Stage. These games include Germany vs. Algeria (Round of 16): 2-1, France vs. Germany (Quarter-Finals): 0-1, Brazil vs. Germany (Semi-Finals): 1-7, Germany vs. Argentina (Final): 1-0. First, the presenter will show the number of total passes and the ball possession rate of each team in each match. These numbers will provide a brief account of each match. Second, the presenter will draw a pass network graph of each team in each match. In the graph, each node represents a player and the location of the node in the network corresponds to the position the player takes in the system of the team. In the graph, the width of each arrow, from player i to player j, shows the number of passes from player i to player j. The graph will give us an overview of passes among the players in the team. Third, the presenter will show the degree centrality (out), degree centrality (in), closeness centrality, betweenness centrality and clustering coefficient of each player. These scores and the coefficient will show which player is the central player and how well the players around each player in the pass network are connected. Fourth, the presenter will show the means of degree centrality (out), degree centrality (in), closeness centrality, betweennes centrality and clustering coefficient of each team. By comparing these means of Germany with those means of the loosing team, we examine the difference between the winner and the loser in terms of centrality and clustering coefficient. Fifth, the presenter will provide centralization scores of degree (out), degree (in), closeness and beweenness, of each team. By comparing these scores between Germany and the loosing team, we can know that the players in Germany do not tend to be one-sided in terms of centrality score, while the players in the losing team tend to be one-sided in terms of centrality score. Sixth, the presenter will provide the standard deviation of the clustering coefficient of each team. By comparing the scores between Germany and the loosing team, we can notice that the degree of connectedness of the players around a player in Germany dose not tend to be one-sided, while the degree of connectedness around a player in the losing team tends to be one-sided. Finally, based on these findings, the presenter will discuss how the strength of Germany as the champion can be quantified using SNA.

2014  An Approach for Integrating Actor-Network Theory and Social Network Analysis: Analyzing Science as Collective Action  単独  2014/09/18 
European Association for the Study of Science and Technology   

概要(Abstract) Science is a form of collective action engaged in by scientists. The purpose of this paper is to show how the integration of actor-network theory (ANT) and social network analysis (SNA) can facilitate a fruitful understanding of science as collective action. First, I review ANT and SNA. According to Freeman, research that examines links among objects of study is called structural. In social science, the structural approach that is based on the study of interaction among social actors is called SNA. SNA is defined by the following features: (1) SNA is motivated by a structural institution based on ties linking social actors, (2) it is grounded in systematic empirical data, (3) it draws heavily on graphic imagery, and (4) it relies on the use of mathematical and/or computational models. Beyond the commitment to these four features, modern social network analysts recognize that a wide range of empirical phenomena can be explored in terms of their structural patterning. Second, I survey preceding studies that have tried to integrate ANT and SNA. Third, I introduce a method used in SNA known as centrality analysis. Fourth, I focus on Callon, Law, and Rip’s use of ANT in their study on qualitative scientometrics. Fifth, I show how applying the method of centrality analysis from SNA to Callon, Law, and Rip’s ANT-based qualitative scientometrics can yield a fruitful quantification of their analysis. Finally, I suggest that integrating ANT and SNA can facilitate a useful understanding of social movements other than science.

2013  Application of Social Network Analysis to FIFA 2010 World Cup Soccer Games: Quantification of the Difference between the Dominant Team and the Outplayed Team  未設定  2014/02/22 
International Network for Social Network Analysis  , Abstracts for Sunbelt XXXIV  , 298   

概要(Abstract) In a soccer game, players pass a ball between one another for scoring a goal. By entering the number of times player i passes the ball to player j into the (i, j) element of an adjacency matrix, we can analyze the game using Social Network Analysis (SNA). The research question in this presentation is how the difference between a dominant team and an outplayed team can be quantified using SNA. As an example of games with difference in ball possession rates, the author cites games from the FIFA 2010 World Cup. At the second stage, the largest difference in the ball possession rate was observed in two games. The games were: Spain versus Portugal (Round of 16) where the ball possession rates were 60% and 40% respectively, and Paraguay versus Spain (Quarter-finals), where the respective rates were 40% and 60%. Spain won both the games and was also the World Cup winner. The author applies structural equivalence analysis, block modeling, and centrality analysis to the two games. By using structural equivalence analysis and block modeling, he indicates that Spain's players were better at passing the ball to each other when compared with the players of the Portugal and Paraguay teams. In centrality analysis, the author suggests that players in the Spain team with high centrality scores did not stay on one side in the team, while in the Portugal and Paraguay teams the players with high centrality scores tended to stay on one side of the team.
