Merging and Creating Culturally Relevant Pedagogy in Public Schools

During the last fifty years, numerous individuals have sought new strategies for students, such as African Americans, whom the public schools have historically underserved. Not only are some parents of these students seeking change, but also researchers, politicians, and local groups. Nevertheless, it is clear that these efforts have posed several dilemmas, which (a) limit the voice and personal choice of learners, (b) standardize the value of learning, and (c) connote a hegemonic discourse. Therefore, this Best Practices essay is based on the theory that a culturally value-driven framework (CVD) of learning will allow African Americans and other students of color to receive an education that promotes personal interest, meaning, and value to their communities

Parallel Maximum Clique Algorithms with Applications to Network Analysis and Storage

We propose a fast, parallel maximum clique algorithm for large sparse graphs that is designed to exploit characteristics of social and information networks. The method exhibits a roughly linear runtime scaling over real-world networks ranging from 1000 to 100 million nodes. In a test on a social network with 1.8 billion edges, the algorithm finds the largest clique in about 20 minutes. Our method employs a branch and bound strategy with novel and aggressive pruning techniques. For instance, we use the core number of a vertex in combination with a good heuristic clique finder to efficiently remove the vast majority of the search space. In addition, we parallelize the exploration of the search tree. During the search, processes immediately communicate changes to upper and lower bounds on the size of maximum clique, which occasionally results in a super-linear speedup because vertices with large search spaces can be pruned by other processes. We apply the algorithm to two problems: to compute temporal strong components and to compress graphs.Comment: 11 page

Application of DWF to heavy-light mesons

We consider application of domain wall fermions to quarks with relatively heavy masses, aiming at precision calculations of charmed meson properties. Preliminary results for a few basic quantities are presented.Comment: Lattice2003(heavy), 3 pages, 3 figure
