  • A Model of Institutionalising Practices by SMEs in China   Order a copy of this article
    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.

  • Estimating the parameters of Software Reliability Growth Models using Hybrid DEO-ANN Algorithm   Order a copy of this article
    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.

  • MULTI - OBJECTIVE OPTIMIZATION OF MAHUA OIL TRANSESTERIFICATION USING RESPONSE SURFACE METHODOLOGY AND GREY RELATIONAL ANALYSIS   Order a copy of this article
    by R.R.Neela Rajan, R. Rajesh 
    Abstract: A mathematical model for the transesterification of Mahua oil was developed at five different process parameters such as catalyst concentration, methanol to oil ratio, reaction time, stirrer speed and extraction temperature. A three - level five factorial Box Behnken - Response Surface Methodology (RSM) was employed to design the experiment. Analysis of variance (ANOVA) of experimental results at 95% confidence level showed that catalyst concentration and methanol to oil ratio were significant process parameters in the transesterification process and the predicted values were quite close to the experimental values, thus, validating the credibility of the model. The Grey Relational Analysis (GRA) was employed to optimize the process parameters for minimizing the viscosity of transesterified mahua oil and maximizing the yield of mahua oil biodiesel.

  • IMPROVING OPERATIONAL EFFICIENCY IN UTILITY SECTOR THROUGH TECHNOLOGY INTERVENTION   Order a copy of this article
    by Sanjay Mohapatra 
    Abstract: The purpose of this paper is to perform an empirical study of factors which determine the improvement of operational efficiency in utility sector. After numerous literature review, the variables that affect operational efficiency were identified which are common across different utilities.All the stake holders were interviewed. The interview was taken using a structured questionnaire, which contained questions mainly on Likert scale. The data was collected from 15 villages and 3 urban areas. Data from 222 respondents was collected, out of which 52 respondents were domestic rural consumers, 50 respondents were domestic urban consumers, 50 respondents were non-government employees, 60 of the respondents were government employees and 10 respondents were expert to the utility The data collected was divided into two sets, the first data set contained data pertaining to rural and urban domestic consumers and the second set contained data pertaining to government employee, non-government employee and experts. The analysis was then done separately for the two sets of data. Thereafter the collected data was analysed using Exploratory factor analysis technique in SPSS. The factors which came out during the exploratory factor analysis were used to perform confirmatory factor analysis by drawing a model in SPSS AMOS. From the analysis, the factors which are most important in determining the operational efficiency of the utility was determined for the two sets of data separately. It was found out that Process re-engineering and reducing AT&C losses are the most important factors that determine operational efficiency. The research was conducted considering certain factors which were conjured to have a role in determining the operational efficiency of a utility. Certain other factors of significance might not have been taken into account. The research was carried out with the responses from the people through a random sampling belonging to a particular region or geography. The scenario might vary with respect to other geographies. Due to time constraint, the sample size was also limited. A greater sample size should be taken to find out the real factors which determine the operational efficiency.
