Let G be a topological group acting on a space X. We construct a family of Steenrod’s ∪i -product [Ann. of Math. (2) 48 (1947) 290] on the Bredon–Illman cochain complex of X [Quart. J. Math. Oxford Ser. (2) 47 (1996) 199]. As corollaries, we get the existence of Steenrod squares on Bredon– Illman cohomology with appropriate coefficients as well as the triviality of the Gerstenhaber bracket indu...

My colleague Richard F. West and I began studies of context effects on the word recognition of children when we were both graduate students at the University of Michigan in the mid-i9705.At the time we were heavily influenced by the popular top-tiown models of the reading process.’ We fully expected to make an experimental mark by providing more rigorous confirmationsof the individual-differenc...

The US has experienced a sustained increase in productivity growth since the mid-1990s, particularly in sectors that intensively use information technologies (IT). This has not occurred in Europe. If the US “productivity miracle” is due to a natural advantage of being located in the US then we would not expect to see any evidence of it for US establishments located abroad. This paper shows in f...

The term “plea bargaining”has become a label often used to describe a series of disparate mechanisms to investigate,prosecute,and adjudicate criminal liability. For some,plea bargaining is the indispensable tool to address criminal conduct,while for others it has become a symbol of coercion and injustice. The purpose of this Article will be to distinguish the very different mechanisms that are ...

Different attempts have been made to answer Reich's question why the majority of those who are hungry don't steal and why the majority of those who are exploited don't strike. The two most influential approaches have been the ideological one and the gunman theory. The gunman theory seems to have the upper hand in that it not only explains many cases of successful oppression by a minority of a m...

Let p(~x) ∈ R[~x] be SOS in t real polynomial squares. Then, p(~x) must have even degree. Let deg(p(~x)) = 2k. Then, ∃q1, . . . , qt ∈ R[~x] s.t. deg(qi(~x)) ≤ k and p(~x) = ∑t i=1 q 2 i (~x). A key observation is that we can now exactly characterise the finitely many possible power-products that could occur in each qi(~x). Definition 1.1. Let Λn(d) = {α = 〈α1, . . . , αn〉 ∈ Nn | α1 + . . .+ αn...

Global health expenditures to prevent and treat diabetes and its complications will total at least US dollar (USD) 376 billion in 2010. By 2030, this number will exceed some USD490 billion. Expressed in International Dollars (ID), which correct for differences in purchasing power, the global expenditures on diabetes will be at least ID418 billion in 2010, and at least ID561 billion in 2030. An ...
