It is not only a complicated but also long-term mission to implement the information system and system project. It involves a variety of interior and exterior problems, such as the supporting from decision management, users' resistance, conflict between departments, leadership of project members, outsourcing¡¦s cooperation, supporting of develop tools (Software & Hardware) and cooperation of supply chain. Therefore, we have defined the social network of the CIO as seven dimensions, which are CEO, users, cross dept. chiefs, MIS dept. employees, Supplies & Clients, Outsourcings & Consultant and Software/Hardware supplies. The research tries to approach the topics from the angle of observer, starting from the social network of the CIO, by case study method, to process the detailed data analysis through a great different of CIO interviews. Thus we may find out and realize the circumstance CIO may faced and the phenomenal incurred in intercourse with the others, which intends to explore that CIO faces the challenge & response while they are trying to push information system in the enterprise. We also take the perspective of Social Capital consists of three dimensions which are structural dimension, cognitive dimension and relational dimension combined as a analyzing perspective to interpret and analyze how the CIO create and take advantage of his social capital to solve problems and achieve the goal eventually. The first finding of the research is that the social network of the CIO was suitable and practicable analyzing perspective based on the three dimensions of social capital theory; secondly, the communication between the correspondents of the CIO social network and CEO is the most importance and the most difficulty as well. The enterprise culture, background, CIO network structure have the influence on intercourse benefit. It is inter-supported with the three dimensions of the social capital. We hereby hope to achieve the following progresses with the research: 1. The reference to the qualified candidate of the CIO to an enterprise. 2. Target on the managers of information management and offer them a brief and simple analyzing perspective, in order to make an accurate diagnose & analysis to the problems. 3. The enterprise could take advantage of social capital to impulse the information system, so that it may reduce information management from any cognitive difference, conflicts between interfaces and get promotion of the service quality of the information department.

Most corporations today have an organizational framework that includes a separation between ownership and management of the company. Along with the Board of Directors, the chief executive officer (CEO) usually has the power to make significant decisions on corporate policy and also takes personal responsibility for the performance of the company. Thus the selection of an optimal CEO is a crucial business decision, and is the focus of this management study. When undertaking the procedures for CEO succession, the members of the Board must select appropriate candidates for the position, as well as deciding upon the CEO¡¦s job responsibilities. The Board evaluates the extent to which the various candidates¡¦ capabilities and experiences match the needs of the corporation. After discussing the pros and cons of each candidate, the Board selects the most appropriate individual for the position. However, certain circumstances often exist that serve to affect this decision process. Specifically, the quality and timing of Board meetings may have a serious detrimental affect on selecting the optimal candidate. By analyzing the literature reviews and annual reports of 682 public companies in Taiwan in 2003, three succession logics of selecting a CEO can be observed: 1) social relationship, 2) political power, and 3) rational capability. From these three logics, the following conclusions can be drawn: 1) The social relationship has the most influence on the selection outcome, with political power acting as the second most influential aspect, and management capability as the third; 2) The influence of the Chairman¡¦s abstract power, as well as his ownership of stock, do not have an obvious influence on the selection outcome, though the Chairman¡¦s control over Board seats has a statistically significant impact on CEO selection; 3) A CEO¡¦s social relationship can not be replaced by his management capability; 4) CEO¡¦s social relationship and stock ownership both have high positive correlation with his involvement of the Board, while the Chairman¡¦s power and the CEO¡¦s management capability don¡¦t.

Abstract This study is based on social capital theory and we made used of the concept of community action as the output of the proposition of social capital theory. The purposes of the study are to discuss rural community elites¡¦ social capital and the application of social capital theory in the participation of community action. In the strategies of analysis, we used community role as an indicator to measure the level of social capital and the participation of community action, and then present the differentiation of rural community elites. In practice operation, social capital could be measuring with two dimensions, including social tie, social network and the social capital of the bridge role (cognitions, trust, and support). The measurement of the participation of community action is based on the concept of community development. And we made use of the indicator¡Xcommunity role to measure the differentiation of rural community elites participation in community action. This study was conducted in three rural communities in the edge of Kaohsiung Metropolitan¡XTashe town, Jenwu town, and Yenchao town.76 valid samples were surveyed .We also made use of the community role as an indicator to separate the rural community elites into five categories, as a comparison and analysis. And this includes: the township office administrators, the local representative, primary school principles, the leaders of social groups, and the directors of community development association. There are four main findings in this study: First, the results to experiment shows that there are some differentiations between the community role of rural community elites in the concepts of social network and the social capital, especially it expressed significantly on the local representative. Second, there are some differentiations when the rural community elites take part in different extent of their community action. But there is no differentiation between the participation of the whole community action. Third, social network is a form of social capital. However, in order to become a form of social capital must work with actions. It causes resources mobility in social network. Also, there will be some differentiations between the community roles if it makes use of social network as social capital by affecting community action. The final one, as the cognitions, trust, and support to the bridge roles of the community by rural community elites, causes their participation of community action. In other words, the social capital owned by the bridge roles affects the degree of rural community elites¡¦ participation of community action.

This research is aimed to build a social network system for college teachers by retrieving different data sources available on the Internet, the characteristics of the constructed social network are represented in graphic and numeric modes. By applying relationships maintained in the social network, we can find the shortest path between any two researchers or the ego-center social network of any individual teacher according to the input parameters given by a query user.. That is to say we have realized the knowledge map concept for college teachers. In this research, we focus on searching the advisory relationships between advisors and students. . Because after a Ph.D. student graduated, he/she could be an advisor guiding other students, by applying recursion of advisory relationships ¡A we can construct a multi-level hierarchy of family-tree for a given advisor and the family-tree can be viewed as a whole family-tree and just those non-leaf nodes. We also analyzed some interesting characteristics of the created family-tree¡A compared with the human relationships in our real society to evaluate and explain some phenomena happened in our academic society. Furthermore, we combine two information of social network and knowledge map for developing the ANIWEB system, providing web-based query functions for users to search teachers¡¦ social network. Two types of query can be applied, one is searching for teacher¡¦s personal information, such as biography, educational background, specialty and NSC projects; the other is searching for social network information about an interested teacher, such as multi-level advisory relationship, co-advisory relationship, ego-center social network and the shortest path between any two teachers. Users can apply different search patterns for their different needs. For example, a user can first search for those teachers with an expertise of a given research topics, then search for the shortest path from the social network to find out the expert he/she could get in touch.

In this thesis, we propose a system for finding friend groups in Blogosphere. This system includes two parts: The first part can traverse the Blogosphere so as to obtain the friend network; and the second part is used to find friend groups from the friend network. Our practical performance was tested on Wretch, which is the largest Blogosphere in Taiwan. In today's blog service environment, the establishments of friend relationships are usually unidirectional, i.e., a blogger can add any other as his friend without confirmation. Traditional methods such as clique/club or 2-clique/club are not suitable because the bidirectional link is built incompletely in the social network under such circumstances. To solve this problem, we propose the 1.5-club based on transitive extension. We further make a comparison among the results of finding groups by 1-club, 1.5-club, 2-club and k-clique, and analyze the historical data of social networks from over almost one year. The experimental results show that our proposed method is effective and promising.

Executive search recruiting by head hunters have been the main and important human resources strategy. In the past, there are a few thesis topics on executive search recruiter (head hunter), and all of these studies focus on either executive search industry or the competency of executive search recruiter. This study surveyed a sample of executive search recruiters island wide, and learn the effects of hunter hunter¡¦s personality trait, human capital and social network on job performance. A brief version of Goldberg¡¦s Unipolar Big-Five Markers was used to evaluate head hunters; as for social networks we focus on four properties of the social network that have been identified as important in the study of executives' networks: the propensity to network, the scope of the network, the strength of ties with network members, and the prestige of network members. The effective sample is 65 after deleting two ineffective questionnaires. The result after regression analysis is as follows: 1. Head hunter¡¦s current job seniority and the seniority of their past original professional field before being a head hunter have a positive impact on their job performance. 2. Having master degree or not and the total seniority of being a head hunter have no obvious impact on job performance. 3. The personality trait of head hunter has impact on their subjective job performance but has no impact on their objective job performance. 4. Head hunter¡¦s social network has no impact on their job performance.

With the advancement of internet technology, online news content has become very popular. People can now get live updates of the world's news through online news sites. Social networking sites are also very popular among Internet users, for sharing pictures, videos, news links and other online content. Twitter is one of the most popular social networking and microblogging sites. With Twitter's URL shortening service, a news link can be included in a tweet with only a small number of characters, allowing the rest of the tweet to be used for expressing views on the news story. Social links can be unidirectional in Twitter, allowing people to follow any person or organization and get their tweet updates, and share those updates with their own followers if desired. Through Twitter thousands of news links are tweeted every day. Whenever there is a popular new story, different news sites will publish identical or nearly identical versions (``clones'') of that story. Though these clones have the same or very similar content, the level of popularity they achieve may be quite different due to content agnostic factors such as influential tweeters, time of publication and the popularities of the news sites. It is very important for the content provider site to know about which factor plays a important role to make their news link popular. In this thesis research, a data set is collected containing the tweets made for the 218 members of 25 distinct sets of news story clones. The collected data is analyzed with respect to basic popularity characteristics concerning number of tweets of various types, relative publication times of clone set members, tweet timing and number of tweeter followers. Then, several other factors are investigated to see their impact in making some news story clones more popular than others. It is found that multiple content-agnostic factors i.e. maximum number of followers, self promotional tweets plays an impact on news site's stories overall popularity, and a first step is taken at quantifying their relative importance.

Technologically mediated listening has changed the way in which music is heard as well as the way in which musical communities are constructed. Communities are no longer necessarily tied to place, and in the case of virtual communities, musicians can create a sense of community and a sense of place through their interactions. Some virtual communities of musicians - specifically those that specialize in electronic music - are ideally situated in cyberspace; what a producer of electronic music hears in his or her headphones when composing music is exactly what the audience hears after downloading or streaming it. The music remains in a digital format from its conception to its reception.In a Brazilian virtual community of electronic musicians called EnergyBR.net, fans, DJs, and producers exchange ideas about music, creating a feedback loop. In EnergyBR.net, this cyber-feedback loop shapes musical creation as well as a sense of place and community.
