This paper considers prior-independent mechanism design, namely identifying a single mechanism that has near optimal performance on every prior distribution. We show that mechanisms with truthtelling equilibria, a.k.a., revelation mechanisms, do not always give optimal priorindependent mechanisms and we define the revelation gap to quantify the non-optimality of revelation mechanisms. This stud...

Classic direct mechanisms suffer from the drawback of requiring full type (or utility function) revelation from participating agents. In complex settings with multi-attribute utility, assessing utility functions can be very difficult, a problem addressed by recent work on preference elicitation. In this work we propose a framework for incremental, partial revelation mechanisms and study the use...

abstract determining whether a surah is makki or madani is an effective way to understand the surah and to choose the most desirable interpretative traditions. there are many surahs considered makki and a few ones considered madani. on the other hand, there is another group of surahs which their dating can be disputable. surah al-ra’d should be put in this group. by analyzing the traditions rel...

The handiwork and the glory of God displayed by the heavens and the firmament have been called General Divine Revelation. In this category one may also include the constitution of human personality, for man himself is a creation of God and in some sense bears the marks of his Creator. This “light of nature and the works of creation and providence do so far manifest the goodness, wisdom, and pow...
