Alternative approach to credit scoring by DEA: Evaluating borrowers with respect to PFI projects

Private finance initiative (PFI), as a form of public/private partnership (PPP), helps to contract the private sector to governmental projects. In contrast to traditional public financed projects, PFI projects are procured by allowing a private sector entity to take the responsibility to design, build, finance, and operate (DBFO) an asset for a contract period of up to several decades. Moreover, banks are perceived to take the leading role in financing PFI projects. Since project financing involves credit assessment of loan applicants, banks have employed popular credit scoring models to assess their creditworthiness. Although the existing models are useful for credit scoring, new models have to emerge in response to ever-changing business practices. This paper therefore aims at introducing the application of data envelopment analysis (DEA) as an alternative credit-scoring model. Unlike traditional credit-scoring building on a formula where weights to a set of criteria are assigned subjectively, DEA will automatically generate the relative weights for analysis. However, incorporating DEA demands additional considerations, which are discussed in this paper. Finally, examples are demonstrated for illustrating this alterative approach to credit scoring by DEA. © 2006 Elsevier Ltd. All rights reserved.link_to_subscribed_fulltex

Examining repercussions of consumptions and inputs placed on the construction sector by use of I-O tables and DEA

This paper aims at introducing the data envelopment analysis (DEA) method to input-output (I-O) analyses. I-O tables have been developed for many decades and have been used extensively to describe and explain economic, social, and environmental issues. One of its major benefits is the derivation of intermediate inputs and demands, which offers more information for data analysis. On the other hand, DEA is argued to be an objective method addressing decision problems. In this paper, it helps to calculate the relative efficiency for each industrial sector based on inputs and outputs of an I-O table. This has extended the static I-O tables to dynamic applications. In order to demonstrate this, five objectives are created to examine repercussions of consumptions and inputs placed on the construction sector in terms of the relative degree of reliance. A numerical example based on the Japanese case is discussed. Based upon the results, strategies and policies can be formulated to overcome difficulties and problems faced by the construction related companies, the construction sector as a whole, and the government as well. © 2005 Elsevier Ltd.

Why Do Some Students Become More Engaged in Collaborative Wiki Writing? The Role of Sense of Relatedness

The article can be viewed at: http://www.opensym.org/os2014-files/proceedings/p400.pdfThis study aims to investigate the role of sense of relatedness in students' engagement in using wikis in collaborative writing. Hong Kong secondary school students (N = 422) participated in the study and answered questionnaires about their sense of relatedness and their level of engagement when using wikis for open collaborative project work. Results from the regression analyses showed that students' sense of relatedness with their teacher and peers facilitated their engagement in the collaborative wiki writing environment. The results were also consistent with the educational psychology research findings in a traditional classroom setting. Most importantly, the result from this study showed the possible linkage between IT in education research and the educational psychology literature. Implications of psychological factors on students' learning in technologically-enriched learning environments are discussed

Impact of cognitive development and training on students’ plagiarism behavior

Symposium Theme: Learning without Limits?Paper Presentation: Parallel Session 2 - Track: Technology-Supported Professional LearningThis research aims to concentrate on how the learner’s cognitive development and additional anti-plagiarism training may affect plagiarism-free learning. This is with regard to Secondary 1 and Secondary 3 students under the context of collaborative learning. Two classes in each grade (Secondary 1 and 3) of a government secondary school in Hong Kong will participate in this study
