The purpose of this study was to investigate the effects of dark side personality traits on self-other rating agreement in leader effectiveness. Data were collected from 80 team leaders and their peers in college. Peers who conducted a team project were asked to assess performance of their team leaders on leader effectiveness, task performance, and contextual performance. The leaders were also asked to self-rate their performance on the same measures. Results indicated that there was disagreement of perceptions about personality traits between leader's self-ratings and the rating of others. First, leaders considered their own Bold, Diligent behaviors as positive influence on their leadership-related criteria, whereas peers of these leaders provided negative ratings. Also, leaders viewed Leisurely and Cautious characteristics as unrelated or negative to performance, whereas peers perceiveed these personality traits as positive to performance. Suggestions for future research were provided based on the findings.

The self-organizing map (SOM) is a unsupervised learning method projecting high-dimensional data into low-dimensional nodes. It can visualize data in 2 or 3 dimensional space using the nodes and it is available to explore characteristics of data through the nodes. To understand the structure of data, cluster analysis is often used for nodes obtained from SOM. In cluster analysis, the optimal number of clusters is one of important issues. To help to determine it, various cluster validity indexes have been developed and they can be applied to clustering outcomes for nodes from SOM. However, while SOM has an advantage in that it reflects the topological properties of original data in the low-dimensional space, these indexes do not consider it. Thus, we propose a new cluster validity index for SOM based on connectivity between nodes which considers topological properties of data. The performance of the proposed index is evaluated through simulations and it is compared with various existing cluster validity indexes.

This study explored three questions: (1) what are the motives of producing and using user-created contents (UCC, video clips which are produced and uploaded at various web sites by individuals), (2) what are the gratifications that users obtain from UCC, and (3) what are the differences of gratifications according to individual uses of UCC. A survey was conducted to 258 UCC users and data were factor-analyzed to find the dimensions of motives and gratifications. As for the motives of UCC uses, six factors were constructed: self-expression, private life, participation, information retrieval, rest, and entertainment, among which self-expression showed the largest variation. As for the gratifications, five factors were constructed: self-expression, rest, information retrieval, socializing, and entertainment.
