A tremendous amount of information is being shared every day on social media sites such as Facebook, Twitter or Google+. However, only a small portion of users provide their location information, which can be helpful in targeted advertising and many other services. Current methods in location estimation using social relationships consider social friendship as a simple binary relationship. Howev...

This paper provides an alternate method of evaluating portfolio performance of stock pricing models. We apply Pitman Closeness Criterion to compare the accuracy of three popular pricing models. This comparison is used to assess which, if any, model outperforms the others. In assessing model performance over a long period of time, we find that the Fama-French three-factor model and the Carhart f...

P/poly, the class of sets with polynomial size circuits, has been the subject of considerable study in complexity theory. Two important subclasses of P/poly are the class of sparse sets 6] and the class of P-selective sets 31]. A large number of results have been proved about both these classes but it has been observed (for example, 17]) that despite their similarity, proofs about one class gen...

The present research addresses the interplay between agency motives and objective dyadic closeness with regard to the functioning of intimate couple relationships. Applying a Person × Situation approach, we hypothesized (a) that partners' implicit and explicit agency motives predict their selection of dyadic living arrangements characterized by high or low objective closeness (coresidence or li...

While historically under-studied in comparison to other family relationships, the fatherdaughter relationship is an important dyad within the family sytem and has been associated with a number of significant psycho-social developmental outcomes for women as they grow from young girls to young adults. Of particular importance is the quality of the emotional connection shared by fathers and daugh...

Identifying active site residues strictly from protein three-dimensional structure is a difficult task, especially for proteins that have few or no homologues. We transformed protein structures into residue interaction graphs (RIGs), where amino acid residues are graph nodes and their interactions with each other are the graph edges. We found that active site, ligand-binding and evolutionary co...
