An important performance measure for a Supply Chain (SC) is the 'total SC profit' (SC surplus). Coordination between SC partners is required to produce higher SC Profit. Information sharing is one of the best mechanisms to ensure and enhance the SC coordination. Literature shows that the lack of coordination and information sharing causes the bullwhip and finally it affects the performance of SC adversely. Chen et al. (2000) studied the impact of forecasting, lead times and information on bullwhip effect in an SC and quantified the same. They proved that the bullwhip effect can be reduced, but not completely eliminated, by centralizing demand information. Studies reveal that the lack of information sharing affects SC responsiveness, inventory cost, replenishment lead time, transportation cost, etc. adversely and they support the importance of this study. It is already found that simulation is a very useful tool for predicting SC performance. Simulation with live players is a good methodology as it involves

The perceptions of employees about six important safety management practices and selfreported safety behaviour are measured with the help of a questionnaire survey administered in eight chemical companies in the state of Kerala in India. One thousand five hundred and sixty six workers participated in the survey with a response rate of 72%. The validity and reliability of the scales are found acceptable. Analysis of the data revealed that employees in companies with OHSAS 18001, ISO 9001 and no certification at all perceive different levels of the above safety variables in them and those in OHSAS 18001 organizations are significantly higher compared with the others. Step-wise regression analysis revealed that four out of six safety management practices predicted safety behaviour in OHSAS 18001 certified organization and three safety management practices were found to predict safety behaviour in the other two groups. But, safety rules and procedures (SR) emerged as a common predictor of safety behaviour in all the three models. This study emphasizes the need for OHSAS 18001 certification to reduce the accidents and thereby to reduce liability and improve productivity and safety and health of employees.

It tries to arrive at conclusions regarding the measurement of incentives due to Human Capital Investment made by nations both at the short run and long run Bridging the gap in human capital requirement between the current and future is a challenge which needs to be addressed starting from nations to organizations and finally by individuals. The paper also discusses the role of education in the twenty-first century and the challenges the sector needs to address to make human capital development focused and productive, above all sustainable in a global perspective. Originality/value: The findings contribute to the existing research scenario by providing important insights with respect to the existing researches and current trends in the area of planning and development of education for the twenty-first century. Limitation: This work has developed a framework for continuous evaluation and development of human capital. However the factors used in the study for measuring human capital should be applied depending upon the category of the institution and employees as a whole. The prevailing environmental factors also should be taken care while measuring the impact of these factors. Operational framework developed in the current research work for human capital is based on expert opinion and literature review. The scope for further research could be about finalizing this framework by testing it in different groups and in geographic regions.

Therefore, risk management in global software development receives attention from many researchers today. The primary focus in this paper is an investigation of risks associated with the maintenance of information systems by teams distributed across geographical locations, cultures, and vendors. Here the authors present the case study of a large offshore outsourced program that maintained a portfolio of business applications for a fortune 500 US client. The program exhibited a wide variety of characteristics typical of maintenance projects. The study investigated the risks, risk resolution techniques, lessons learned and best practices adopted in the program, from a vendor perspective. The findings provide useful insights into understanding and responding to the challenges in initiating, transitioning and managing global software maintenanc...

Empirical testing of a model formed is done by a questionnaire survey conducted among the selected Small and Medium Enterprises (SMEs) in India. Univariate tests indicate the significant influence of forecasting usage, type of forecasts, standardization, training and learning on SME performance. Combined influence on firm performance is analysed by means of a logistic regression model. Use of forecasting, standardization and learning orientation influenced the SME performance and take a role in classifying below and above performing firms. Less importance is given to training. Use of forecasting, standardization and training methods are to be improved. Features of above and below performers provide information to industry people. Conceptual and measurement models may give input to researches and may help to improve the existing models. This study is a particular one conducted in the Indian SME context.

As in other spheres, here too, despite the vast extent of interactive and participatory software practice and theory, there is still little shared understanding amongst those involved. The success of a software project is directly affected by the lack of understanding and estimating stakeholder's needs and expectations along with lack of effective communication amongst the software stakeholders. The following paper aims to understand the existing software stakeholder management techniques in IT industry. This will further help in dealing with unforeseen circumstances and potential risks.

Measurement plays a key role in science, technology and industry. Where there are measurements there is associated errors. Study of measurement errors has a long history. Attempts have been made to classify and understand the factors that contribute to errors in measurement. The understanding of this is useful for error reduction and also providing the margin for errors and reducing damage caused due to errors. For the purpose of classification and study, measurement errors have been divided into instrument error, method error and human error. The former two are easier to study and correct, but the later is less understood. In this study an attempt has been made to study the effect of selected work related variables on human errors in observing and noting measurements which contribute to measurement errors. In a measuring system, though some of the effects of variables on measurement errors can be guessed, only an experimental study will be able to isolate, quantify and present the effect of each variable separately. Hence an experimental study was designed and conducted to quantify and present the effect of selected work related variables of two sets of human subjects used in the experiments. Analysis of the results revealed that the variables identified and studied have significant effect on measurement errors, and their effects were also separately quantified. This will be of use to professionals trying to reduce measurement errors, especially in industrial environments, where knowing the variables and the extent of error they induce, appropriate work related settings can be adopted to keep human errors within the tolerable limits.

In this paper the crystallisation behaviour of coconut oil and the effect of additive addition and the chemical modification on its pour point were analysed using differential scanning calorimetry (DSC). Coconut oil showed the highest pour point among the vegetable oils considered in the study. This can be attributed to the predominantly saturated nature of its fatty acid constituents. Addition of additives did not show any significant improvement in the pour point of coconut oil. The chemical modification procedures described in this work have been effective in improving the pour point of coconut oil to some extent. The DSC method used in the present work has been found to be helpful in understanding the crystallisation behaviour of vegetable oils with different fatty acid compositions, the effect of additive addition and the chemical modification on pour point of coconut oil.

As we know, the revolution in information technology (IT) has ushered in significant changes to software engineering practices, as well as IT business models. These happenings have resulted in changes to software risk perception and risk management. While there are numerous studies on software risk, we need a thorough investigation of contemporary Industry practices to build a software risk management model that is practically useful. Based on an investigation of 145 software projects, we propose a model for risk management applicable to non-inhouse projects. We explain the distinctive features of our model in comparison with the existing literature on software risk. The model identifies the key focus areas of software risk management in offshored or outsourced projects in order to achieve the best outcome.
