Cost-Effective Location Management for Mobile Agents on the Internet

Abstract: Many mobile agent system-related services and applications require interacting with a mobile agent by passing messages. However, an agent’s mobility raises several challenges in delivering messages to a mobile agent accurately. Consisting of tracking and message delivery phases, most mobile agent location management schemes create or receive many update messages and interaction messages to ensure the effectiveness of the schemes. In addition to downgrading the overall performance of a mobile agent location management scheme, excessive transmission of messages increases the network load. The migration locality of a mobile agent and the interaction rate between mobile agents significantly affect the performance of a mobile agent location management scheme with respect to location management cost. This work presents a novel Dual Home based Scheme (DHS) that can lower the location management costs in terms of migration locality and interaction rate. While the DHS scheme uniquely adopts dual home location management architecture, a selective update strategy based on that architecture is also designed for cost-effective location management of mobile agents. Moreover, DHS is compared with available schemes based on formulations and simulation experiments from the perspective of location management costs. Simulation results demonstrate that the proposed DHS scheme performs satisfactorily in terms of migration locality and interaction rate.

Individual Fund Manager Sentiment, Fund Performance and Performance Persistence

Abstract: This study contributes to the literature by examining the relation among fund performance, performance persistence and individual fund manager sentiment, rather than the fund industry sentitment. This study employs the turnover rate as the proxy of individual fund manager sentiment. Using the one and two-way sorting methods and the panel data regression analysis, this study finds that the equity funds in Taiwan have performance persistence in the both short and long run. We find the funds with a higher turnover rate (i.e., higher fund managers’ sentiment) perform better no matter they are in the winner or loser groups. This phenomenon persists both in the short- and long-terms, which implies the influence of sentiment on the performance is persistent. The investors should choose winner funds due to their persistence, and choose those whose turnover rate is in top 40% of the winners.

Partial Least Squares Structural Equation Modeling in Online Shopping: the Moderator Effect Between Impulsive Buying Tendency and Behavior

Abstract: Single’s Daywas first promoted by Alibaba's shopping website on November 11, 2009. Ten years later, Taobao successfully developed this day into a global carnival shopping festival. This research focuses on undergraduate business school students through online questionnaires across the Taiwan Strait. This study is based on five impact factors, including impulse buying tendencies, herd behavior, website features, promotional techniques and impulse buying behavior. No evidence showed that gender, age and monthly disposable income affect students’ buying behavior. This study also found that herd behavior, website features and promotional techniques are moderator effects between impulse buying tendency and impulse buying behavior. We also proved that website design and the opinions of their peers affect consumers' decision aking. According to the analysis, in the current online shopping environment, operators should pay more attention to herd behavior, website features and promotional techniques. This study suggests that the industry should provide sufficient information to reduce emotional conflict, and use these important factors to attract consumers' future purchases.

Impacts of day trading on the intraday pattern of market quality

Abstract: In Taiwan's stock market, buying first and selling later, as well as selling first and buying later, are permitted, as of January 1, 2014, and June 30, 2014, respectively. This study investigates day trading stocks (pilot stocks) and non-day trading stocks (control stocks) that appear in the Taiwan 50 index and Taiwan mid-cap 100 index during 2013–2014, with the goal of investigating the impact of day trading on the intraday pattern of market quality. With the difference analysis and cross-sectional regression analysis, this study reveals insights into a stock market that is populated mainly by individual investors. Prior research into intraday patterns of market quality rarely focused on individual investors. The current study demonstrates that the effective spread of pilot stocks decreases significantly, and trading depth increases significantly, after the implementation of buying first and selling later options. This liquidity increase phenomenon then is offset when the selling first and buying later option is permitted.
