This study is the first to analyze performance of Taiwanese domestic equity funds between January 2009 and October 2014, the period during which quantitative redirected capital flows toward developing economies and the Taiwanese Stock Exchange Weighted Index compounded at approximately 12.9% annually. Adopting methods endorsed by earlier research, we evaluated 15 Taiwanese equity funds' performance relative to market averages using the Sharpe (1966) and Treynor (1965) ratios and Jensen's alpha method (1968). To test market timing proficiency, we applied the Treynor and Mazuy (1966) and Henriksson and Merton (1981) regression analysis methods. Jensen's alpha method (1968) was used to measure fund managers' stock selection skills. Results revealed that funds significantly under-performed Taiwan's average annual market return and demonstrated no exceptional stock-selection skills and market timing proficiency during the era of quantitative easing.

As many companies have adopted and used ERP systems, concerns about ERP performance also have increased. The purpose of this research is to examine the relationships between qualitative variables and quantitative variables measuring ERP performances. Qualitative research, widely used in MIS research, typically examines perceived usefulness of ERP, such as information quality, system quality, system satisfaction. Quantitative research, often done in accounting research, usually examines ERP performance based on financial statements. An empirical study led to the following conclusions: 1) There were significant correlations among the qualitative variables measuring perceived usefulness of ERP; 2) Significant correlations were also observed among the quantitative variables based on financial statements; 3) However, no significant correlations was found between the qualitative variables and quantitative variables measuring ERP performance.

The interest in performance evaluation of public R&D has been dramatically increased. Many tries have been made to measure and to evaluate the quality of research performance. Quantitative indicators are considered increasingly important for this purpose. The most widely used are the number of research articles, citations and Impact Factors. However, such indicators are strongly discipline-dependent, and hence they should be used with careful attention. In this study we tried to provide quantitative evidence on the latent problems of discipline-dependent indicators. We also tried to provide a set of quantitative indicators for evaluating publications as a result of research activities. We put our focus on the quantitative indicators reflecting the characteristics on disciplines and provided several indicators with guideline on their usage.

Today, the importance of test and evaluation of defense systems is increasing day by day. In performing efficient defense systems test works, process improvement based on quantitative management is essential. The purpose of this paper is to present the results of process improvement for the defense systems test works of the test organization based on quantitative management activities. As a methodology to confirm process improvement performance, the 'MPM(Managing Performance and Measurement)' practice area of the CMMI model was applied. The quantitative management model for defense systems test works was developed so that it could be practically applied not only to the entire test organization but also to the organization at the department level that actually performs the test work. Finally, the application cases of the quantitative management model for defense system test works and the results of process improvement were described.

For Barrier-Free certification, the floor and ground surfaces must be finished with materials that are not slippery, flat, and have low-impact in fallis. However, the BF Certification Act does not provide specific methods to meet these regulations. In performance-based design, the responsibility of proving the performance rests with the building owner and architect, so quantitative evaluation indexes are needed to select suitable materials. Furthermore, changes in performance after completion should be checked periodically in 'As-Is' conditions. There are various methods for slips, trips and falls risk assessment, causing confusion for users. In this study, the results of previous studies on the evaluation methods of slips, trips and falls were considered closely, and each quantitative evaluation index that can be used in the new construction and maintenance phase was presented.

As the need for quantitative qualities of IT investment performance heightens, numerous research organizations are developing various measurement methods for the quantitative evaluation and its currency value conversion. Corporations utilizing these methods to evaluate IT investment performance are gradually increasing. However, working-level staff in the corporations that have introduced the quantitative evaluation can not assure if the evaluation sufficiently reflects the actual effect provided by IT since the results arising from the conversion of currency value can't be visibly confirmed. This study tries to identify whether the quantitative evaluation of IT investment performance can be explained in terms of the level of consumer satisfaction proven by the qualitative evaluation by analyzing the level of consumer satisfaction and quantitative evaluation of a case company and identifying the correlation between them. As the result of the case study, the following points have been concluded. Firstly, the currency value of IT effect correlates with the level of consumer satisfaction. Secondly, in order to come up with a rational currency value of IT effect, developing an indicator as well as managing data on currency conversion that will enable the internal system's efficiency to become more quantitative is essential. Thirdly, IT ROI is not appropriate to compare the performance between systems and is utilized as a measurement standard for each system's performance and efficiency. Lastly, quantitative evaluation is still inadequate in the evaluation of the system's strategic side, and consumer satisfaction can be utilized as a supplementary method.

The purpose of the present research was to investigate developmental trends in children's class-inclusion performance and to examine the influence of task characteristics(provision or deprivation of quantitative information and perceptual information) on a class-inclusion task. The subjects of this study were 96 children, 12boys and 12girls at each age level. 5, 6. 7 and 8 years of age. The experimental materials consisted of 12 stimulus boards which were constructed on the basis of picture cards used by Judd and Mervis(1979) and Lane and Hodkin(1985). The class-inclusion tasks were individually administered by the researcher. The data were analyzed by the statistical methods of t-test, one-way ANOVA and Duncan multiple range test. The results showed that (1) There were significant age differences in children's class-inclusion performance. That is, children's performance scores on the class-inclusion task increased with age.: (2) There were significant task characteristics differences in children's class-inclusion performance. That is, children performed better on the deprivation of quantitative information task than on the provision of quantitative information task.

In this paper, we suggest a quantitative management scheme to accomplish effective weapon systems test and evaluation service(T&E). The Capability Maturity Model Integration(CMMI) process model has been introduced and applied for that purpose by the 8th directorate, Agency for Defense Development(ADD). Although a CMMI process model was developed focusing on the software development, systematic approaching scheme in the CMMI process model can be utilized for the quantitative management implementation of a weapon systems T&E service. To manage a T&E service quantitatively, at first, organizational performance objectives and sub processes are established, and then each performance indicators and performance base lines are followed.

The purpose of this study is to investigate how software policy shows the moderating effects between organizational capability maturity and organizational performance. The software policy includes the proportions of development personnel and development budget that can affect organizational performance. It is important to empirically identify whether the ratios of budget and personnel, which are some of the main policy indexes of the organization can promote the causal relationship between organizational maturity and organizational performance. These personnel and budget may be assumed to affect the causal relationship between organizational capability maturity and organizational performance. The results of this study shows that the moderating effects of software policy are partially proved. The two policy indexes, personnel ratio and budget ratio, showed a moderating effect between process implementation and organizational performance, but did not show any moderating effect between quantitative management and organizational performance. This is because the companies participating in the survey are still in the early stages of quantitative process management and quantitative management does not show the differentiated results among the participating organizations. The significance of this study is as follows. In the academic aspect, the causal relationship between organizational maturity and organizational performance was examined empirically, and it was analyzed whether the two adopted policy indicators have a moderating effect between organizational maturity and organizational performance. On the practical side, the analysis suggested that the ratios of budget and personnel emphasized by the government or organization played a role of facilitating the organizational maturity and organizational performance.

Many enterprises are interested in using the IS development methodologies as a means of increasing system performance and solving the problems of delayed delivery time, excessive budget, and failure of integrated systems. Even if previous researches showed that the system productivity and quality improvement using the system development methodologies are very poor, we tried to find that the methodologies are meaningful as an innovative means for IS performance. We defined that the IS development methodology as a technical and managerial innovation for IS department. We intended to study the relationship between the implementation process of the IS development methodology divided into four steps and IS performance. A cross-sectional field survey with IS departments of domestic companies was conducted, and we used LISREL 8.12a to perform the structural equation model analysis and hypothesis verification. We found the meaningful relationship between the development methodology and qualitative performance. We reconfirmed that the relationship between the development methodology and quantitative performance is not meaningful as expected, which is the same result with the previous researches. But the qualitative performance affects very strongly to the quantitative performance. As a results, we suggest that IS managers and developers keep the principles of the IS development methodologies to get the quantitative performance through the qualitative performance improvement.
