Extended model reduces the redundancy of roles, lowers the complexity of authorization management and enhances the flexibility and maintainability of users＇ authorization. It is well proved in its application in postgraduate student management system.展开更多

During analysis and interpretation of data, some touch of context is also given to clear the picture of weakness and strengths of project theory in terms of context. The main objective of project under study was to provide alternative energy to the communities living inside forest to reduce wood cutting for domestic purpose. Though there were many short term surveys were conducted during project, such as, average wood consumption at household level, community motivation survey. Instead to all MRDS （Mehran Research ＆ Development Society） felt need to conduct a detailed impact evaluation to see overall impact of project implementation and review on the life of end users or communities. After three years of project exit, MRDS conducted a qualitative impact study of project in the end of 2014. There were three key questions to explore during study： What was the overall impact of project on end users？ What the best practices of project and why？ What are project learnings and how？展开更多
