We trace the difference between the ways in which apes and humans co-operate to differences in communicative abilities, claiming that the pressure for futuredirected co-operation was a major force behind the evolution of language. Competitive co-operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future-directed...

Is thought computation over ideas? Turing, and many cognitive scientists since, have assumed so, and formulated computational systems in which meaningful concepts are encoded by symbols which are the objects of computation. Cognition has been carved into parts, each a function defined over such symbols. This paper reports on a research program aimed at computing these symbolic functions without...

The research presented in this paper shows that merely activating the idea of money affects the social behavior and social preferences of young children who do not understand the economic functions of money. From an economic point of view, money is universal, instrumental, and can be defined by the functions that it provides. From the psychological point of view, money is more symbolic and emot...

We present Symbolic Quick Error Detection (Symbolic QED), a structured approach for logic bug detection and localization which can be used both during pre-silicon design verification as well as post-silicon validation and debug. This new methodology leverages prior work on Quick Error Detection (QED) which has been demonstrated to drastically reduce the latency, in terms of the number of clock ...

We study interrelations between symbolic descriptions of concurrently evolving systems and underlying sequential dynamics. We focus our interests on minimal shifts and t-shifts generated by them, assuming that an independence relation is given by a five vertex co-graph.

Nuclear receptor coregulators are coactivators or corepressors that are required by nuclear receptors for efficient transcripitonal regulation. In this context, we define coactivators, broadly, as molecules that interact with nuclear receptors and enhance their transactivation. Analogously, we refer to nuclear receptor corepressors as factors that interact with nuclear receptors and lower the t...

we need sociology theories, for that understand of sociology and politic problems. french sociologist pierre bourdieu's theory practice and symbolic power are our best resource; for understanding social and political fields. this article reviews the language and symbolic power; indicating its function in social and political fields. we need sociology theories, for that understand of sociol...
