If uniform coding (Gödelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME 6= EXPSPACE = 2-EXPTIME, and, for all p, we have p−EXPSPACE = p+1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2); the proof fails, when relativized to oracle-TM’s. A by-product of this research is that PTIMEF is not closed under number-...

according to philosophers, the soul is an immaterial essence that can be perfected by knowledge and action. but how does the soul perfect through knowledge and action? what is the way of perfection? furthermore, is such perfection stopped by death or does its life continue after death? in this paper, i will explain avicenna’s answers to these questions. also, i will examine the problem of the p...

The primary mode of reception in computer games is play. This implies that the agency performed by computer players does not limit itself to the process of reading, but is constituted by a creative enactment of the structures of interactive actions and events inherent in the game. As such, gameplay may be regarded as a kind of (unpaid) immaterial labour, implying players’ socialization, creativ...

In this paper, we compare the cause and effect of immaterial rewards and sanctions on cooperation in a voluntary contributions experiment. We find that both rewards and sanctions increase contributions only when subjects interact repeatedly, though rewards seem to be more effective than sanctions. Moreover, in contrast to sanctions, rewards do have an impact on future contributions. Although th...
