A Methodology facilitating Knowledge Transfer to both research experienced companies and to novice SMEs
by Magnus Holm, Marcus Frantzén, Tehseen Aslam, Philip Moore, Lihui Wang
Abstract: In this paper, knowledge transfer is defined as a process of disseminating both technological and theoretical understanding as well as enhancing both industrial and academic knowledge through conducted research to project partners collaborating within a research project. To achieve this, a new methodology called user groups is introduced. It facilitates knowledge transfer between project participants in collaborative research programmes engaging both experienced and unexperienced partners regardless of level of input.rnThe introduced methodology user groups provides tools for collaborating with several research partners even though their levels of engagement in the project and prior research experience may vary without dividing them into separate groups. It enables all project partners to gain new knowledge and by so doing extending the Knowledge Society. The case study shows that the eight engaged companies are able to cooperate, achieve their own objectives and, both jointly and individually, contribute to the overall project goals.
Keywords: methodology facilitating knowledge transfer; technology transfer; SME; Small and medium enterprises; knowledge society.
Learning in Academic Enterprise- A study on Antecedents using Lisrel 8.7 and Smart PLS 2.0
by A. K. KRANTHI, A.T.Resmi
Abstract: The concept of Learning Organizations has its application across the various disciplines in different sectors which aim at continuous improvement. Education sector particularly higher education with special reference to the universities will fit in into this concept perfectly. Universities being the knowledge intensive organizations often face the criticism of not being a learning organizations. The reason can be attributed to the lack of leadership of immediate supervisor that leverages affective commitment of the faculty members by psychologically empowering them followed by lack of commitment and empowerment among the faculty members. Thus, the present paper empirically puts forth the impact of affective commitment on Learning Organization when mediated by resonant leadership and psychological empowerment in university faculty context. To keep up with the pace in the prevailing competitive scenario, it becomes a conscious mandate for the universities to unlearn the conventional process and switch over to the process of organizational learning. Unlearning the old process and learning the new process always calls for the gesture of acceptance and willingness to move forward from faculty members. They also are expected to be committed. Affective commitment alone doesnt cater to the need of learning organization, since the commitment in the context of university faculty is often triggered by a leadership of the immediate supervisor who holds a crucial role in psychologically empowering the employees. This calls for the need to address the relation between affective commitment, Resonant Leadership Psychological empowerment and the concept of Learning Organization.
Keywords: Key words: Learning Organization (LO), Organizational Learning (OL), Organizational Commitment (OC), Resonant Leadership, Psychological Empowerment (PE).
An Efficient Radon Mapped Discrete Wavelet Transform Based Algorithm for MC-CDMA System.
by Sowmy I, Jayakumari j
Abstract: The proposed work is aimed at improving bit error rate (BER) performance and spectral efficiency, increasing data rate, reducing intersymbol interference (ISI) and interchannel interference (ICI). Implementation of a conventional MC-CDMA system normally involves the use of QAM techniques for mapping. In the proposed work a mapping technique which is based on finite radon transform is used. The use of finite radon transform (FRT) improves orthogonality between the subcarriers. It also reduces Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI), which is due to the loss of orthogonality between carriers. Since discrete wavelet transform (DWT) is used instead of Fast Fourier transform (FFT) which is employed in conventional Multi-Carrier CDMA techniques, the insertion of guard interval is not required and it offers better spectral efficiency. Result shows that the Bit Error Rate performance of the proposed algorithm is far better than conventional techniques in AWGN channel.

STATISTICAL ANALYSIS ON CENTRALIZATION OF SOFTWARE TESTING ORGANIZATION AND ITS IMPACT ON PRODUCTION DEFECT AND COST OF TESTING
by Sanjay Mohapatra, Suman Kumar Kanth, P.C. Basak
Abstract: Software testing is a critical component in the shifting paradigms of software development because of the changing nature of technology and the increasing complexity of real time changes impacting in this area. Still the area is very less researched and the impacts have been less analysed statistically. In practice cost and quality are the two important items apart from the on time delivery. Centralization and partial centralization of testing units in the organizations is one such area where organizations always struggle to see the impact. Knowledge management is another area where the changes are explicit but never well researched. This study tries to fill that gap where the impact of the centralization of testing unit and the knowledge management process on Production Defect and Cost of Testing is analysed on the basis of statistical model. The survey conducted with practitioners gives us the reliable data points to conclude that these variables positively impact the researched topics however their impacts vary in terms of their significance. It is sincerely hoped that this research will give a stage for further researches happening in the area of software testing and its centralization in an organization.
Keywords: Centralized Testing Unit; Knowledge Management; Production Defect; Software Testing; Cost of Testing.
A Model of Institutionalising Practices by SMEs in China
by Jonathon Hu, John Stanton
Abstract: How and to what effect small businesses in China build and utilise their guanxi networks as an informal institution remain unanswered questions. Modelling and testing a model of institutionalising, or the performance-conducive managerial practices involved in building, leading, and utilising a SMEs guanxi institution, is the purpose of this paper. Drawing from the literature and interviews we propose key aspects of institutionalising practices, the antecedents of each aspect, and a survey questionnaire which were hand-delivered to 308 SMEs in China, achieving 212 valid samples. Governing, Diversifying, Weaving, Sharing and Distributing, the five institutionalising aspects hypothesised in the SME institutionalising model, were found to moderately covary with each other and contribute significantly to SME performance. The strategic actions corresponding to the five aspects can help a SME identify its institutionalising deficiencies and acknowledge its institutionalising achievements. The model also enables SME stakeholders to effectively explain, anticipate and respond to institutionalising actions. The findings indicate that institutionalising is not only to gain institutional legitimacy as suggested in the extant literature, but also to strive for institutional prestige within the Chinese institutional environment.
Keywords: institution theory; Chinese business network; guanxi; SME.

Estimating the parameters of Software Reliability Growth Models using Hybrid DEO-ANN Algorithm
by Shailee Lohmor, B.B. Sagar
Abstract: The parameter estimation of Software reliability growth model (SRGM) is extremely useful for software developers and has been broadly acknowledged and applied. However, each SRGM contains some undetermined parameters and estimation of these parameters is a fundamental task. Mostly, these parameters are estimated by the Least Square Estimation (LSE) or the Maximum Likelihood Estimation (MLE). However, these methods impose certain constraints on the parameter estimation of SRGM like requiring the modelling function. In this paper, we propose an efficient approach to estimate the parameters of software reliability growth model (SRGM) using a Hybrid Dolphin Echolocation Optimization-Artificial Neural Network (DEO-ANN) through parallel computation. The DEO is utilize to optimize the weights and the structure of the ANN to reduce computational complexity. The performance of the proposed approach for parameter estimation of SRGM is also compared with other existing approaches. The experimental results show that the proposed parameter estimation approach using DEO-ANN is very effective and flexible, and the better software reliability growth performance can be obtained on the different software failure datasets.
