Dynamic capabilities have been widely discussed in the past decade but how the determinants of dynamic capabilities affect a firm's competitive advantage has not been fully explored. This paper develops a quantitative method to investigate how a firm's dynamic capabilities affect a firm's competitive advantage. This study examines the developed hypotheses through a questionnaire survey of 165 firms together with a number of interviews drawn from Taiwan's information and communication technology industry. The results suggest that three determinants of dynamic capabilities (i.e., path, process, and position) influence a technological firm's competitive advantage in different ways. Both position and process have direct positive impacts on firm competitive advantage while position also has a mediating effect on the relationship between process and firm competitive advantage. This paper closes with theoretical and practical implications. [ABSTRACT FROM PUBLISHER]

Short Message Service (SMS) is the most popular mobile data service today. In Taiwan, a subscriber sends more than 200 short messages per year on average. The huge demand for SMS significantly increases network traffic, and it is essential that mobile operators should provide efficient SMS delivery mechanism. In this paper, we study the short message retransmission policies and derive some facts about these policies. Then, we propose an analytic model to investigate the short message retransmission performance. The analytic model is validated against simulation experiments. We also collect SMS statistics from a commercial mobile telecommunications network. Our study indicates that the performance trends for the analytic/simulation models and the measured data are consistent. [ABSTRACT FROM AUTHOR]

The article provides information on the activities during the 11th Optoelectronics and Communications Conference held from July 3-7, 2007 in Kaohsiung, Taiwan. Workshops of the conference were held on July 3, which focuses on the radio telecommunication on fiber technologies. In the first workshop, issues of the feasible photonic networks were discussed. Furthermore, in the regular technical sessions, maximum 6 sessions were progressed in parallel. In the post deadline session, 8 hot topics were reported.
