Preparing faculty for eTeaching : leading horses to water?

In February this year, Deakin University launched Deakin Studies Online (DSO), its institution-wide learning management system (LMS) powered by WebCT Vista. Previously academics had a variety of applications available to them (and still do until DSO is fully implemented by late 2004) to support teaching and learning. These include TopClass, FirstClass, WebCT 3.6 and various custom-built systems and web pages.

Reuse of learning objects? why, how and when?

This paper describes the rationale behind the specification and acquisition of a Digital Objects Management System (DOMS) at Deakin University. Key drivers are: compliance with the provisions of the Digital Agenda Act for the communication of copyright works; improved management of Deakin’s intellectual property, and reduction in costs of delivering online content via a learning management system.

Details of the desired functionality and potential integration issues are addressed. During the specification stage, additional uses for a digital object management system were identified that relate to the broader notion of knowledge management, and these will be discussed.

At the time of writing, no decision has been made as to which vendor(s) will be successful in gaining the University’s contract for the management of digital learning objects.

Using social software to support the teaching of IT professional practice

Social software has been used to support problem-based learning activities in a wholly online information technology (IT) professional practice course at Deakin University since 2006. When the course was first delivered, the authentic learning environment was a website, with an intranet and team forums created in Drupal, the open source content management system (CMS). Although this environment was suitable, feedback from students and teaching staff highlighted areas where improvements could be made. In the second year of the course, Joomla!, the open source CMS, in combination with Simple Machines Forum (SMF), the open source online discussion community software, was used to provide the website, as well as the intranet and team forums respectively. Feedback in 2007 was more positive, suggesting that the Joomla!-SMF social software combination and the features implemented, improved the learning and teaching experience in comparison to the 2006 version of the course.

Increasing population happiness through the distribution of resources

This paper concerns the ways in which public policy regarding the distribution of resources might be used to increase the happiness of the Thai population. The term happiness refers to the subjective side of life quality, which in contemporary science is more commonly referred to as subjective wellbeing (SWB). The SWB construct is described within the theoretical context of SWB homeostasis. This is a proposed management system which has the role of maintaining a positive view of the self. It will be described how the homeostatic system can be challenged by hardship. The resources that the system requires to manage such challenges will also be described. Recommended forms of SWB measurement will be considered. It is concluded that public policy which directs resources to disadvantaged population sectors may be one of the most effective initiatives to enhance population wellbeing and national productivity.

Reforms in the Bangladesh agriculture input sector : room for complacency?

Market-based reforms implemented in the agricultural input management system are often claimed to be one of the success stories in Bangladesh. Based on the findings of 154 surveys and 16 in-depth interviews with the stakeholders during 2003-2004, the paper found that although there have been some notable achievements, the reforms have not achieved their expected outcomes and more importantly, in cases where they have been achieved, their sustainability is in question. The paper discusses the underlying reasons for the success and the problems of the reforms and also offers some policy recommendations to resolve the gap between the expected and the achieved outcomes. In the context of increasing donor pressure for adopting market-based reforms, the findings are likely to have important implications for both the donors and other countries in South Asia.

Students' perceptions of the value of the elements of an online learning environment : looking back in moving forward

In 2003, Deakin University implemented a centralised learning management system (LMS) under the banner of Deakin Studies Online (DSO), as well as implementing policies requiring all its units of study to have at least a basic online presence from 2004. Given the scope of the university's commitment to online education, it was considered essential to evaluate the effectiveness of this investment. Based on more than 5400 responses obtained from students in 2004 and 2005 as part of the DSO evaluation survey, the analysis presented here identifies those elements of the online learning environment (OLE) that are most used and valued by students, those elements of the OLE that students most want to see improved, and, those factors that most contribute to students' perceptions that use of the OLE enhanced their learning experience. The most used and valued elements were core LMS functions, including accessing unit information, accessing lecture/tute/lab notes, interacting with unit learning resources, reading online discussions, contacting lecturers/tutors and submitting assignments online. The OLE elements identified as most needing attention were receiving feedback on assignments; viewing my marks; and reviewing unit progress. Students felt that using DSO enhanced their learning experience when they were adequately supported by unit teachers and technical support services; when they were able to find and use unit information; and when they were able to read the online contributions of other unit members. The retrospective analysis of data collected in the period 2004-2005 has been shaped by a forward-looking agenda. The array of elements available within, and in association with, traditional LMSs which has emerged since that time raises the future challenge of how to maximise and evidence educational value through the optimal combination of elements from the portfolio of e-learning technologies increasingly available to educators.

Online discussion in engineering education : student responses and learning outcomes

A ubiquitous and widely used feature of online learning environments is the asynchronous discussion board. This chapter presents a case study of the introduction and evaluation of student use of an online discussion in an engineering management study unit. We introduced an assessable assignment task based on student use of an online discussion, in response to falling student unit evaluation results after we initially moved the unit to wholly online delivery mode. Both quantitative and qualitative unit evaluation data suggest that students perceive value in the online discussion activities. A regression analysis based on discussion usage data suggests that students derived significant learning outcome benefit toward their final unit grade from making reflective postings in the online discussion.

Students' perceptions of the value of the elements of an online learning environment : an investigation of discipline differences

This paper presents a large scale, quantitative investigation of the impact of discipline differences on the student experience of using an online learning environment (OLE). Based on a representative sample of 2526 respondents, a number of significant differences in the mean rating by broad discipline area of the importance of, and satisfaction with, a range of elements of an OLE were found. Broadly speaking, the Arts and Science and Technology discipline areas reported the lowest importance and satisfaction ratings for the OLE, while the Health and Behavioural Sciences area was the most satisfied with the OLE. A number of specific, systematic discipline differences are reported and discussed. Compared to the observed significant differences in mean importance ratings, there were fewer significant differences in mean satisfaction ratings, and those that were observed were less systematic than for importance ratings.

Guest editorial : In Journal of networks, v.7 n.3

Networking of computing devices has been going through rapid evolution and thus continuing to be an ever expanding area of importance in recent years. New technologies, protocols, services and usage patterns have contributed to the major research interests in this area of computer science. The current special issue is an effort to bring forward some of these interesting developments that are being pursued by researchers at present in different parts of the globe. Our objective is to provide the readership with some insight into the latest innovations in computer networking through this. This Special Issue presents selected papers from the thirteenth conference of the series (ICCIT 2010) held during December 23-25, 2010 at the Ahsanullah University of Science and Technology. The first ICCIT was held in Dhaka, Bangladesh, in 1998. Since then the conference has grown to be one of the largest computer and IT related research conferences in the South Asian region, with participation of academics and researchers from many countries around the world. Starting in 2008 the proceedings of ICCIT are included in IEEExplore. In 2010, a total of 410 full papers were submitted to the conference of which 136 were accepted after reviews conducted by an international program committee comprising 81 members from 16 countries. This was tantamount to an acceptance rate of 33%. From these 136 papers, 14 highly ranked manuscripts were invited for this Special Issue. The authors were advised to enhance their papers significantly and submit them to undergo review for suitability of inclusion into this publication. Of those, eight papers survived the review process and have been selected for inclusion in this Special Issue. The authors of these papers represent academic and/or research institutions from Australia, Bangladesh, Japan, Korea and USA. These papers address issues concerning different domains of networks namely, optical fiber communication, wireless and interconnection networks, issues related to networking hardware and software and network mobility. The paper titled “Virtualization in Wireless Sensor Network: Challenges and Opportunities” argues in favor of bringing in different heterogeneous sensors under a common virtual framework so that the issues like flexibility, diversity, management and security can be handled practically. The authors Md. Motaharul Islam and Eui-Num Huh propose an architecture for sensor virtualization. They also present the current status and the challenges and opportunities for further research on the topic. The manuscript “Effect of Polarization Mode Dispersion on the BER Performance of Optical CDMA” deals with impact of polarization mode dispersion on the bit error rate performance of direct sequence optical code division multiple access. The authors, Md. Jahedul Islam and Md. Rafiqul Islam present an analytical approach toward determining the impact of different performance parameters. The authors show that the bit error rate performance improves significantly by the third order polarization mode dispersion than its first or second order counterparts. The authors Md. Shohrab Hossain, Mohammed Atiquzzaman and William Ivancic of the paper “Cost and Efficiency Analysis of NEMO Protocol Entities” present an analytical model for estimating the cost incurred by major mobility entities of a NEMO. The authors define a new metric for cost calculation in the process. Both the newly developed metric and the analytical model are likely to be useful to network engineers in estimating the resource requirement at the key entities while designing such a network. The article titled “A Highly Flexible LDPC Decoder using Hierarchical Quasi-Cyclic Matrix with Layered Permutation” deals with Low Density Parity Check decoders. The authors, Vikram Arkalgud Chandrasetty and Syed Mahfuzul Aziz propose a novel multi-level structured hierarchical matrix approach for generating codes of different lengths flexibly depending upon the requirement of the application. The manuscript “Analysis of Performance Limitations in Fiber Bragg Grating Based Optical Add-Drop Multiplexer due to Crosstalk” has been contributed by M. Mahiuddin and M. S. Islam. The paper proposes a new method of handling crosstalk with a fiber Bragg grating based optical add drop multiplexer (OADM). The authors show with an analytical model that different parameters improve using their proposed OADM. The paper “High Performance Hierarchical Torus Network Under Adverse Traffic Patterns” addresses issues related to hierarchical torus network (HTN) under adverse traffic patterns. The authors, M.M. Hafizur Rahman, Yukinori Sato, and Yasushi Inoguchi observe that dynamic communication performance of an HTN under adverse traffic conditions has not yet been addressed. The authors evaluate the performance of HTN for comparison with some other relevant networks. It is interesting to see that HTN outperforms these counterparts in terms of throughput and data transfer under adverse traffic. The manuscript titled “Dynamic Communication Performance Enhancement in Hierarchical Torus Network by Selection Algorithm” has been contributed by M.M. Hafizur Rahman, Yukinori Sato, and Yasushi Inoguchi. The authors introduce three simple adapting routing algorithms for efficient use of physical links and virtual channels in hierarchical torus network. The authors show that their approaches yield better performance for such networks. The final title “An Optimization Technique for Improved VoIP Performance over Wireless LAN” has been contributed by five authors, namely, Tamal Chakraborty, Atri Mukhopadhyay, Suman Bhunia, Iti Saha Misra and Salil K. Sanyal. The authors propose an optimization technique for configuring the parameters of the access points. In addition, they come up with an optimization mechanism in order to tune the threshold of active queue management system appropriately. Put together, the mechanisms improve the VoIP performance significantly under congestion. Finally, the Guest Editors would like to express their sincere gratitude to the 15 reviewers besides the guest editors themselves (Khalid M. Awan, Mukaddim Pathan, Ben Townsend, Morshed Chowdhury, Iftekhar Ahmad, Gour Karmakar, Shivali Goel, Hairulnizam Mahdin, Abdullah A Yusuf, Kashif Sattar, A.K.M. Azad, F. Rahman, Bahman Javadi, Abdelrahman Desoky, Lenin Mehedy) from several countries (Australia, Bangladesh, Japan, Pakistan, UK and USA) who have given immensely to this process. They have responded to the Guest Editors in the shortest possible time and dedicated their valuable time to ensure that the Special Issue contains high-quality papers with significant novelty and contributions.

Analysing business processes to manage and resolve strategic issues in a manufacturing business

This paper demonstrates the value of applying heuristics to knowledge systems of business processes in a manufacturing company to resolve strategic issues and enable the attainment of strategic business goals. The manufacturing company was losing market share through not being able to get its new products to market quickly enough. The research illustrates the ‘location’ and use of information systems in a manufacturing context. The researchers collected the specific business process knowledge in the company and developed a knowledge management system and then applied heuristics to the ‘AS IS’ manufacturing process to determine better models of manufacturing that would enable faster to market product development and thus enable better strategic alignment between company expectations and realisation of market share. The paper highlights the strategic use of information systems as a means of directly solving business problems.

KM value creation : evidence from a case

One of the fundamental knowledge management questions is how organizations can use their knowledge to create value. There is general agreement that knowledge management should add value. It is not clear, however, what value means in the context of knowledge management and how it is created. This fundamental question is complex as value has different meanings to different people. Understanding value in the context of KM will lead to better understanding of the potential sources of value creation from knowledge management and better management of knowledge assets. It will inform the measurement of knowledge and its impacts on organizations. It will lead to recognition of the contribution of knowledge assets to organizational success.

This paper provides a review of prior research on value creation and how this can improve the understanding of value in the context of knowledge management. Based on this review it poses questions to explore value creation in the context of knowledge management. It then reports on preliminary analysis of a case study of a process-based knowledge management system and the expressions of value, value creating actions and value capture as perceived by different stakeholders.

The determinants of happiness

Measures of mood happiness are increasingly used to assess the development and progress of nations. The limitations of this approach are, however, considerable. Within developed nations population happiness is quite resistant to change, despite major improvements in the objective standard of living. The reason, we propose, is that levels of subjective wellbeing are psychologically managed for each person, to be held around their genetically determined 'set-point'. This homeostatic management system acts to keep people feeling normally positive about them self, and so resists change. Thus, the search for 'happiness determinants' in the form of objective circumstances is often unrewarding in normally functioning samples. Due to homeostatic resistance, changes in objective variables will have weak effects on mood happiness. If large changes in mood happiness are found, they can be attributed to homeostatic failure and represent pathology.
