Abstract  

This paper surveys 32 renowned Industrial Engineering (IE) journals with regard to authorship for the period of 1996–2005. The findings show that the USA was the top contributing country, accounting for approximately one-third of the total number of articles. The 80/20 rule and the entropy measure consistently identify Issues in Science and Technology (IST), Industrial Engineer (IE), and R&D Magazine (RDM) as journals of high country concentration, or journals of low internationality. Conversely, Journal of Materials Processing Technology (JMPT), Production Planning & Control (PPC), and Technovation (TNV) have the highest degree of country diversity, or internationality. The quality of a journal, as expressed by impact factors, its internationality, and its number of articles published, are found to be independent of each other.

Abstract  

This paper surveys 56 internationally renowned OR journals published in 1996–2005 with regard to authorship. Our findings show that the USA was the country that contributed the largest amount, approximately one-third, of research results to OR journals. Authors tend to publish papers in their home-country journals. Journal of the Operations Research Society of Japan has the highest author concentration, with more than 85% of the authors from Japan and European Journal of Operational Research, on the contrary, has the widest country spread of its authors. The entropy measure provides a whole picture of the share of all countries, based on which the editorial policy of a journal can be adjusted.

Abstract  

As the major concerns of the university are teaching and research, this paper describes the study of a nation-wide evaluation of research performance in management for 168 universities in Taiwan. In addition to the popular indicators of SCI/SSCI journal publications and citations, the number of projects funded by the National Science Council of Taiwan was used to account for the special characteristic of the field of management. The evaluation was based on individual professors rather than management programs, so that all types of universities, including those without management departments, could be compared. Performances of each university in those three indicators were aggregated by a set of a posteriori weights which were most favourable to all universities in calculating the aggregated score. The results show that public universities, in general, performed better than private ones. Universities with specific missions had comparable performance to general comprehensive ones. Analyses from a set of a priori weights solicited from experts showed that the results of this study are robust to the indicators selected and the weights used.

Abstract

Research performance is difficult to evaluate because most of the criteria are incommensurable, and assessing its improvement over time is even more difficult. This paper assesses the performance improvement in management research in Taiwan between 2006 and 2010 using the Malmquist productivity index (MPI). The criteria for measuring research performance are journal publications, where the journals are classified as SI-, TI-, other international-, and other local-types. While the number of papers has increased for three types and decreased in one, the MPI indicates that the aggregate performance has improved significantly. The areas of management covered in this study are management information systems, production and operations management, and marketing. For all these areas the performance has improved, although the improvement in marketing is insignificant. The assessment sheds some light on the area and category of journals that contribute to the improvement of research performance, and which are useful for setting goals to reach higher levels.

Abstract  

Radiotherapy widely uses the polymer gel dosimeter. The advantage of polymer gel dosimetry is the mapped 3D absorbed dose distribution that other dosimeters cannot achieve. The Acrylamide (AAm) is a frequently used monomer; however, the extreme toxicity of Acrylamide (ORL-RAT LD50: 124 mg/kg) raises a concern. Therefore, this study developed a new type of Propylene acid based gel dosimeter, named DEMBIG gel. The following outlines the aim of this study: (1) using two-point formulation to find the optimal scan parameter of MRI according to the best sensitivity and linearity (correlation coefficient) of DEMBIG gel, (2) using the optimal scan parameter of MRI to observe the properties of DEMBIG gel, and (3) verifying the three-dimensional (3D) dose distributions of radiotherapy. This study obtained three major results: 1. The scan protocol of MRI was established. 2. The preliminary results of DEMBIG gel were: (1) The range of absorbed dose of DEMBIG gel: 0–20 Gy. (2) The sensitivity and correlation coefficient of DEMBIG gel at verification as slope: 0.181 sGy−1, R 2:0.997. (3) There is no energy dependency of the DEMBIG gel. 3. The dose difference was 3% in the three-dimensional (3D) isocenter dose in clinical radiotherapy. These data show that DEMBIG gel is a potential candidate for the 3D dosimeter.

Abstract  

To improve the quality of journals in Taiwan, the National Science Council (NSC) of the Republic of China evaluates journals in the fields of humanities and social sciences periodically. This paper describes the evaluation of 46 management journals conducted by the authors, as authorized by the NSC. Both a subjective approach, with judgments solicited from 345 experts, and an objective approach, with data collected on four indicators: journal cross citation, dissertation citation, authors’ scholastic reputation, and author diversity, were used to make a comprehensive evaluation. Performance in the four indicators were aggregated using weights which were most favourable to all journals, in a compromise sense, to produce the composite indices. The subjective evaluation reflects the general image, or reputation, of journals while the objective evaluation discloses blind spots which have been overlooked by experts. The results show that using either approach alone would have produced results which are misleading, which suggests that both approaches should be used. All of the editors of the journals being evaluated agreed that the evaluation was appropriate and the results are reasonable.
