Consider the problem of deciding whether a graph is 3-colorable. This problem is NP-complete. The optimization version of this problem is, given a 3-colorable graph G, color it using as few colors as possible. In the regime of polynomial time approximation algorithms, this problem has been studied extensively [Wig82, Blu94, KMS98, ACC06, Chl07]. The current best known approximation factor is ac...

S tudents often approach the familiar stories of the Bible wondering what more they can learn from texts they have been reading since childhood.As teachers, we face the challenge of getting students to focus on the text itself, without being overly influenced by the preconceptions and interpretations that have become attached to these stories through centuries of retelling and commentary. One d...

The coevolution of environment and living organisms is well known in nature. Here, it is suggested that similar processes can take place before the onset of life, where protocellular entities, rather than full-fledged living systems, coevolve along with their surroundings. Specifically, it is suggested that the chemical composition of the environment may have governed the chemical repertoire ge...

Some 30 years after integrative theory was first introduced to criminology as an explicit attempt to move beyond mono-disciplinary thinking (Jeffrey, 1978; Johnson, 1979; Elliott, Agerton, & Canter, 1979; Elliott, Huizinger & Ageton, 1985; Colvin & Pauly, 1983; Hawkins & Weis, 1985; Pearson & Weiner, 1985; Messner, Krohn, & Liska, 1989; Akers, 1994; Hagan, 1989), it is surprising that criminolo...

Over the past two decades, the contribution that a rich learning environment makes toward attaining educational goals such as improvement in learning achievements and attitudes towards studies and school has been considered in educational research (Fraser, Giddings, & McRobbie, 1995; Fraser & Tobin, 1991; Perkins, 1992). The term rich learning environment not only includes physical devices, suc...

We show a tight relation between the behavior of unique games under parallel repetition and their semidefinite value. Let G be a unique game with alphabet size k. Suppose the semidefinite value of G, denoted sdp(G), is at least 1− ε. Then, we show that the optimal value opt(G) of the `-fold repetition of G is at least 1 − O( √ `ε log k). This bound confirms a conjecture of Barak et al. (2008), ...
