Syou-Ching Lai, Cecilia Lin, Hung-Chih Li and Frederick H. Wu
Published January 2010
This study examines the economic consequences of internet financial reporting (IFR) in Taiwan. The results show that the stock prices of IFR firms change more quickly than those of the non-FR firms using Akaike’s (1969) Final Prediction Error (FPE) methodology. Second, the results from the event study methodology show that the cumulative abnormal returns of the firms with IFR are significantly higher than those of the firms without IFR. Lastly, the results indicate that firms with a higher degree of information transparency yield a higher abnormal return on theirstock prices.
|Visualizing Basic Accounting Flows: Does XBRL + Model + Animation = Understanding?
Byron Marshall, Kristian Mortenson, Amy Bourne and Kevin Price
Published March 2010
The usefulness of XBRL (eXtensible Business Reporting Language) in facilitating efficient data sharing is clear, but widespread use of XBRL also promises to support more effective analysis processes. This format should allow managers, investors, regulators, and students to aggregate, compare and analyze financial information. This study explores an XBRL-based visualization tool that maps the organization of financial statements captured in the XBRL formalism into a graphical representation that organizes, depicts, and animates financial data. We show that our tool integrates and presents profitability, liquidity, financing, and market value data in a manner recognizable to business students. Our findings suggest the promise of XBRL-based visualization tools both in helping students grasp basic accounting concepts and in facilitating financial analysis in general.
|Discovering Important Factors of Intangible Firm Value by Association Rules

It is very important for investors to understand the critical factors affecting the value of firms before making investments. In knowledge-based economy, the method for creating firm value transfers from traditional physical assets to intangible knowledge. As intangible assets value is an important part of firm value, valuation of intangible assets becomes a widespread topic of interest in the future of economy. This paper applies association rules, one data mining technique, to discover critical factors affecting firm value in Taiwan and to provide a more flexible model than the traditional regression method. Based on collecting related factors found in literature, the results indicate that R&D intensity, family, participation in management, pyramids, profitability, and dividend are the six important factors, in which some are consistent with significant important variables in prior literature, but most of them are unique for Taiwan, one emerging economy.
|Trends of e-Government Research. Contextualization and Research Opportunities

Published July 2010
E-Government is a broad research field in which researchers are currently involved in a
range of different research projects. Our purpose in this paper is to assist researchers in the
development and direction of future analyses, identifying trends in terms of research and the
methodology used. Universities and departments that make the main scientific contributions are
identified, in order to locate and contextualize the research carried out into e-Government and to
enhance intercommunication among researchers and thus knowledge in this field. To achieve this
goal, we examined periodical publications listed in the Social Science Citation Index (SSCI) of the
Institute for Scientific Information (ISI) in the fields of Public Administration and Information
Science, during the period 2000-2009. Knowledge gaps and research opportunities have been
derived, highlighting the need to use quantitative methodologies and to identify key factors to promote a theoretical framework to enhance the efficient implementation of e-Government, as well as identification the main universities where the researchers can complete their doctoral academic training.
|The Implementation of Free Software in Firms: an Empirical Analysis
Carmen de Pablos Heredero, David López Berzosa and Roberto Santos Santos
Published September 2010
This article presents the findings of a research aimed at characterizing open source migration initiatives. Thirty experiences have been considered in total, ninety of them are Public Administrations and the rest are private firms, operating different industries in eight different countries. Open source migration projects have become a recent research topic, especially from the managerial perspective. To overcome the lack of theoretical models, an empirical approach relying on grounded theory has been adopted. This inductive approach allows theory building and hypothesis formulation. According to the results, migrating from proprietary into open source is dependent on contextual and organizational factors, as for example, the need of the change itself, the political support for the change, the access to IT resources, the organizational climate, the motivation of the human resources, and the leadership style for the project or the firm complexity. Besides, migration efforts imply strategic and organizational consequences that the organization must properly evaluate beforehand.
|Analysis of XBRL Literature: A Decade of Progress and Puzzle
Saeed Roohani, Zhao Xianming, Ernest A. Capozzoli and Barbara Lamberton
Published November 2010
XBRL (eXtensible Business Reporting language) was recently, in 2008, in its 10th year. The concept was articulated in 1998 by Charles Hoffman, known as XFRML (eXtensible Financial Reporting Mark Up Language) to facilitate the business reporting process and improve financial reporting. The objective of this paper is to examine a decade (1998-2008) of XBRL articles published in various publications including trade, practitioner and academic journals to identify trends and patterns, milestones, and organizations actively contributed to this development. Another goal is to assess public perceptions of XBRL, its capabilities and its future. We examined published articles where XBRL appeared either in the title or abstract of the article during 1998-2008. Considering that XBRL reporting is being required only in recent years, the research shows various interest groups worked together for a long time to achieve a common goal. The academic community has also been proactive in contributing to and assessing this new reporting standard. There is a trail of research articles to document this contribution. This paper provides various charts and interesting statistics.
