Social ties play an important role in today's competitive world. The primary objective of this study is to explore the impact of intra- and inter-social ties on team innovativeness and performance. Through an empirical model of 97 teams in six companies, this study attempts to (i) examine how intra- and inter-social ties affect team innovativeness and team performance; and (ii) investigate how the support for information technology facilitates social ties. Our team-based analysis reveals that strong intra-bonds among members improve team innovativeness and enhance team performance. Inter-linkages among teams also lead to team performance through innovativeness, but they are not directly associated with performance. IT support also considerably enhances social ties.

This research empirically examined the determinants of competitive advantages and performance of Korean film industry from 1996 to 2003 over a sample of 396 movies. Especially, the effects of knowledge-based resources, social capital, product differentiation strategy, and market entry strategy on a film performance were hypothesized and empirically tested. Findings of this study are as follows; First, confirming the importance of knowledge-based resources in film industry, both the superior business track records of producers and the superior artistic track records of directors and actors had positive effects on film performance. Second, supporting social capital hypotheses, while the strong ties between directors and producers had positive effects, the strong ties between directors and actors had negative effects on film performance. Third, confirming the importance of product differentiation strategy, genre differentiation against competing films had positive effects on film performance. Finally, confirming the importance of market entry timing, the number of competing films released following a film opening within a week had negative effects on film performance. The findings of this research suggest that producers, directors, and actors are not only the critical knowledge-based resources to create competitive advantages indeed, but the pattern of relationships among them also systematically influences the film performance. Moreover, it is suggested that film performance may be improved by the proper genre differentiation and opening day selection.

The purpose of this study is to examine the effect of social anonymity on community quality and find out mediating factors that affect the relationship between social anonymity and community quality in online community sites. This study focuses on the factors such as self expression, self control, and community ties to investigate their mediating roles on the relationship between social anonymity and community quality. Also, discussion quality and information quality are used to measure online community quality. The results of this study show that social anonymity is directly related to discussion quality but not related to information quality. As for the mediating effects, self expression, self control and community ties are all shown to have strong mediating effects on the social anonymity and community quality relationship.

Knowledge residing in the heads of employees has always been regarded as one of the most critical resources within a firm. However, many tries to facilitate knowledge transfer among employees has been unsuccessful because of the motivational and cognitive problems between the knowledge source and the recipient. Social capital, which is defined as "the sum of the actual and potential resources embedded within, available through, derived from the network of relationships possessed by an individual or social unit [Nahapiet and Ghoshal, 1998]," is suggested to resolve these motivational and cognitive problems of knowledge transfer. In Social capital theory, there are two research streams. One insists that social capital strengthens group solidarity and brings up cooperative behaviors among group members, such as voluntary help to colleagues. Therefore, social capital can motivate an expert to transfer his/her knowledge to a colleague in need without any direct reward. The other stream insists that social capital provides an access to various resources that the owner of social capital doesn't possess directly. In knowledge transfer context, an employee with social capital can access and learn much knowledge from his/her colleagues. Therefore, social capital provides benefits to both the knowledge source and the recipient in different ways. However, prior research on knowledge transfer and social capital is mostly limited to either of the research stream of social capital and covered only the knowledge source's or the knowledge recipient's perspective. Social network theory which focuses on the structural dimension of social capital provides clear explanation about the in-depth mechanisms of social capital's two different benefits. 'Strong tie' builds up identification, trust, and emotional attachment between the knowledge source and the recipient; therefore, it motivates the knowledge source to transfer his/her knowledge to the recipient. On the other hand, 'weak tie' easily expands to 'diverse' knowledge sources because it does not take much effort to manage. Therefore, the real value of 'weak tie' comes from the 'diverse network structure,' not the 'weak tie' itself. It implies that the two different perspectives on strength of ties can co-exist. For example, an extroverted employee can manage many 'strong' ties with 'various' colleagues. In this regards, the individual-level structure of one's relationships as well as the dyadic-level relationship should be considered together to provide a holistic view of social capital. In addition, interaction effect between individual-level characteristics and dyadic-level characteristics can be examined, too. Based on these arguments, this study has following research questions. (1) How does the social capital of the knowledge source and the recipient influence knowledge transfer respectively? (2) How does the strength of ties between the knowledge source and the recipient influence knowledge transfer? (3) How does the social capital of the knowledge source and the recipient influence the effect of the strength of ties between the knowledge source and the recipient on knowledge transfer? Based on Social capital theory and Social network theory, a multi-level research model is developed to consider both the individual-level social capital of the knowledge source and the recipient and the dyadic-level strength of relationship between the knowledge source and the recipient. 'Cross-classified random effect model,' one of the multi-level analysis methods, is adopted to analyze the survey responses from 337 R&D employees. The results of analysis provide several findings. First, among three dimensions of the knowledge source's social capital, network centrality (i.e., structural dimension) shows the significant direct effect on knowledge transfer. On the other hand, the knowledge recipient's network centrality is not influential. Instead, it strengthens the influence of the strength of ties between the knowledge source and the recipient on knowledge transfer. It means that the knowledge source's network centrality does not directly increase knowledge transfer. Instead, by providing access to various knowledge sources, the network centrality provides only the context where the strong tie between the knowledge source and the recipient leads to effective knowledge transfer. In short, network centrality has indirect effect on knowledge transfer from the knowledge recipient's perspective, while it has direct effect from the knowledge source's perspective. This is the most important contribution of this research. In addition, contrary to the research hypothesis, company tenure of the knowledge recipient negatively influences knowledge transfer. It means that experienced employees do not look for new knowledge and stick to their own knowledge. This is also an interesting result. One of the possible reasons is the hierarchical culture of Korea, such as a fear of losing face in front of subordinates. In a research methodology perspective, multi-level analysis adopted in this study seems to be very promising in management research area which has a multi-level data structure, such as employee-team-department-company. In addition, social network analysis is also a promising research approach with an exploding availability of online social network data.

The primary goal of this study is to identify disintegration and reconstruction of the family/kinship structure in the rapidly industrializing urban area, Seoul. For this purpose, detailed data about (1) the value related to the family and kinship (2) the family relationship, especially marital relationship (3) the attitude of divorce and remarriage (4) the characteristics of the social network (5) the family/kin rites and attitude about the rites are gathered. A total of 716 subjects completed structured questionnaires. Major conclusions of the study are as follows: Firstly, most of the respondents are found not to support familism and boy preference, and they show an ambivalence about the child value analyzed by concepts of the cost and reward. Secondly, most of the respondents perceive that marital relationship has been changed toward the direction of increased relative importance of wives' opinion in the decision making process within the family. However, they believe that husbands still have more power than their wives. Respondents also believe that parents have more power than their children. Thirdly, most of the respondents view divorce as an altemative to unhappy marriage. It was also shown that relatively few have negative attitude toward remarriage. Fourthly, the social network of the respondents is characterized by two distinct trends, namely, strong parent-child ties and narrowed kin relationship. Fifthly, the urbanization and the introduction of western life style have disrupted the traditional rites of passage. But ancestral rites serve to confirm family ties, especially the gathering of siblings to perform ancestral rites for parents. Therefore foreign element exist in parallel with pre-existing traditional elements.

The purpose of this study is to investigate actual conditions of family/kin ritual transition and to find out relationships to socio-economic variables. For this purpose, 716 subjects of urban family were interviewed with questionnaires. The results of this study may be summarized as follows: 1. It was discovered the pervasive themes of family/kin ritual transition: westernization, commercialization, socialization, and cultural anomie. 2. In contemporary family/kin rites, traditional structure coexists with external westernized aspects under the influnce of industrialization and commercialization. The rites were continued to provide a place where participants reproduce the ideology of patriarchal family group, especially the strong parent-child ties and narrow kin relationships. 3. Respondents who support traditional ritual style are old, lower class, and Buddhist. 4. Respondents who support westernization and socialization of family/kin rites are young, higher class, and Christian. But family/kin rites are not affected by sex relatively.

This study applied the network text analysis to reveal the scope and trends of low cost carrier studies. We analyzed low cost carrier research published in Korean journals and news articles. The results showed that there are three clusters in terms of research topics. First dimension consists of articles investigating growth in the low cost carrier industry. The second dimension is associated with service characteristics. The last dimension has strong ties organizational and human resource dimension. We run Krkwic, Krtitle, Netdraw, and Ucinet 6.0 to conduct the network text analysis. This study suggests the direction of low cost carrier research in the future.
