from rosana's point of view, following the decline of the dominant role of states in the international arena, the world system has changed from a uni-polar to a multi-polar system. in the new system, there are many independent players. in crease in citizen's knowldge and individual expertise is one of the charactristics of our new world. in this era, legitimacy is no longer derived fr...

The performance of three optics-based interference cancellation systems are compared and contrasted with each other, and with traditional electronic techniques for interference cancellation. The comparison is based on a set of common performance metrics that we have developed for this purpose. It is shown that thorough evaluation of our optical approaches takes into account the traditional noti...

Cross efficiency evaluation was developed as an extension of DEA. But the traditional DEA models usually have alternative optimal solutions and, as a result, cross efficiency scores may not be unique. It is recommended that without changing the DEA efficiency scores, the secondary goal should be introduced for optimization of the inputs/outputs weights.  Several reports evaluated the perfo...

implementing information technology projects requires a calculated process to prevent failure. at the same time application of information technology in organizations faces various potential risks. exploring information technology environment in organizations reveals the potential risks and provides a structure for comprehensive risk management. there are various methods available for risk mana...

results the accuracy for detecting number of main renal arteries were not different in both groups which were 96.7% in ct angiography group and 90% in traditional angiography group (p = 0.15). the accuracy for detection of main renal veins were 100% in group 1 and 96.7% in group 2 (p = 0.31). patients and methods a total number of 60 living kidney donors who underwent open surgical approach for...

With the development of RS technology, the evaluation of DOM becomes more important. Multi-level fuzzy comprehensive evaluation is the traditional method for DOM evaluation. But in the process of traditional multi-Level Fuzzy Comprehensive Assessment, the weight of evaluation factor which are subjective is always ascertained by experts. The method can cause evaluation bias because of the subjec...

The aim of Information Systems (IS) evaluation research is to produce ever more detailed answers to the question of why an IS initiative works (better) for whom and in what circumstances. This paper presents an alternative to traditional IS evaluation research approaches. The alternative, realistic IS evaluation research, is based on the philosophy of critical realism. Realistic IS evaluation r...

The traditional trustworthiness evaluation of running software is inaccurate and incomplete because each component is as an independent unit during reliability evaluation. According to the drawbacks of traditional models, this paper proposed a trustworthiness evaluation approach of component-based software based on level. The trustworthy behavior trace diagram of componentbased software was pre...

Design science consists of two major design processes: building and evaluation. A wellexecuted evaluation of design artifacts is crucial to their success. Traditional evaluation tools have certain weaknesses because design artifacts include “wicked” problems. Serious Gaming can help to overcome these problems. To this end an online based cloud resource managing game is developed which simulates...
