Things that can and things that can ’ t be done in PRA Ulrich

Details of Work Done by Lura

In this paper a review is presented based on experimental studies done on high performance concrete. The compiled test data revealed distinct differences in the mechanical properties of normal, high strength and high performance concrete. Shape of the specimen ( cube, cylinder, beam etc), size of specimen, magnitude of temperature load applied on the specimen, percentage of fibers varied in the...

Things That Can and Things That Cannot Be Done in PRA

Things that can and things that can’t be done in PRA

It is well-known by now that large parts of (non-constructive) mathematical reasoning can be carried out in systems T which are conservative over primitive recursive arithmetic PRA (and even much weaker systems). On the other hand there are principles S of elementary analysis (like the Bolzano-Weierstraß principle, the existence of a limit superior for bounded sequences etc.) which are known to...

Pursuing goals with others: group identification and motivation resulting from things done versus things left undone.

This article addresses what factors best motivate individuals to work toward shared goals. We propose that when individuals do not identify highly with a group, their contributions will mimic others': An emphasis on things done will increase their contributions toward achieving a goal, because such emphasis suggests the goal is worth pursuing. Conversely, we propose that when individuals identi...
