Understanding information system quality on public e-government service intention: an empirical study

Taqwa Hariguna; Min Tsai Lai; Chung-Wen Hung; Shih-Chih Chen

The aim of this study is the proposition of a model for the understanding and examination of public satisfaction and intention towards e-government service. Based on the online survey of 366 e-government experienced participants, this study uses the structural equation modelling approach to test the research model. The results of analysis reflect that public intention use is significantly determined by public satisfaction, and perceived usefulness toward e-government, and information system quality (ISQ) is positively influenced by public intention usage directly, while public perceived usefulness directly is influenced by ISQ, and indirectly influenced through public confirmation of expectation. Other results indicate that public satisfaction is directly influenced by ISQ and indirectly influenced through public perceived usefulness. Finally, the findings of this research offers detailed theoretical, and managerial implications for scholars, governmental and software engineering.

Preventive replacement policy with cumulative repair-cost limit for a system under increasing failure rate shock model

Min Tsai Lai; Chung-Wen Hung

A system is subject to shocks and these shocks are divided into two types: non-lethal and lethal shocks. Non-lethal shocks increase the failure rate of the system along with the age of the system and make the system eventually into a minor failure. Lethal shock whenever occurs makes the system critical failure. This shock process is called an increasing failure rate shock model. A minor failure is corrected by minimal repair, while a critical failure is rectified by replacement. In this paper, we propose a periodical replacement policy for a system, incorporating with the concept of cumulative repair-cost limit. While carrying out minimal repair, the repair cost and the accumulated repair cost are calculated. The system is replaced at age T or a minor failure at which the accumulated repair cost exceeds a predetermined threshold L or at a critical failure. The minimum-cost replacement policy is studied and a sensitivity analysis is conducted to evaluate the effect of model parameters on the optimal T*.

Efficient Storage and Retrieval of XML Documents Using XQuery

Yu-Bin Chiu; Huei-Huang Chen; Chu Yen Liu; Shih-Chih Chen; Chung-Wen Hung

XML has already been the standard of data interchange on the Internet. Nowadays, a large amount of data is represented in XML format. However, most of the critical data in businesses are still stored in relational database management systems. It is difficult to query XML databases because of its textual format. This research intends to tackle this problem, and we proposed a system to manage XML documents that could be queried by the query language XQuery. XML documents are stored in relational format and the XQuery expressions are translated into appropriate SQL queries. The results of the SQL queries are transformed into XML documents. Comparing with LegoDB System, our system reduces processing time to search a relation configuration and proposes a better translating and executing technique which is more efficiently.

Expiration Day Effects and Futures Trading Profits: Evidence from Taiwan

Edward H. Chow; Chung-Wen Hung; Christine Shu-Hua Liu; Cheng-Yi Shiu

We set out in this study to analyze the expiration effects of index futures on the cash market in Taiwan, and find that both volatility and trading volume are higher on the final settlement days as compared to normal trading days. We also calculate the volume of open interest for final settlement relating to different classes of traders, as well as the profits from the open interest positions of these traders in index futures contracts. We find that proprietary traders exhibit superior performance whereas foreign investors achieve the worst returns. Our empirical results provide strong evidence in support of the view that the expiration effects in the Taiwan futures market are partially attributable to attempts at ‘marking the close’.

Stock Liquidity and the Choice between Public Offerings and Private Placements

Chung-Wen Hung; Cheng-Yi Shiu; Hui-Shan Wei

This study attempts to verify whether stock liquidity is an important determinant of the choice between public offerings and private placements. Using a sample of 628 SEOs in Taiwan stock market, we find that, ceteris paribus, firms with highly liquid stocks prefer public offerings, whereas firms with illiquid stocks tend to engage in the private placement of new shares. We also find that issuers experience poor operating performance prior to the private placements. Our findings suggest that private placements serve as a substitute for public offerings when the issuing firms are unable to gain access to the public market.
