Social networking sites have gained popularity among all populations, especially young adults. Personality traits were found to be predictive of how individuals use social media. Therefore, this study sought to examine the association between shyness and self-disclosure to a Facebook friend as well as self-disclosure to a face-to-face friend. Two studies were conducted. The first study tested h...

Sugars are the OPERATING SYSTEM (OS) of the body, processing DNA data, thought, and all cellular communication. Glycomics, the science of sugars, may be thousands of times more complex than the genome project. The eight Royal Sugars used to construct glycoprotein receptor sites that coat every healthy human cell were described by Robert K. Murray, M.D., PhD, in Harper’s Biochemistry first in 19...

Community portals such as blogs, wikis and photo sharing sites have become the new channels for information dissemination on the Web. When searching for information, many results end up in some type of community site. However, one cannot make use of the wealth of information that is available through the preferences of one's thematic social network, or through bookmarks or other documents, only...

We have used the Vimos VLT Deep Survey in combination with other spectroscopic, photometric and X-ray surveys from literature to detect several galaxy structures in the Chandra Deep Field South (CDFS). Both a friend-of-friend based algorithm applied to the spectroscopic redshift catalog and an adaptative kernel galaxy density and colour maps correlated with photometric redshift estimates have b...

This article addresses the ongoing, increasing privatization of peer-to-peer (P2P) file sharing systems – the emergence of systems that users may only join by personal, friend-to-friend invitation. It argues that, within P2P systems, privacy is increasingly coinciding with “mere” invisibility vis-à-vis the rest of the Internet ecosystem because of a trend that has shaped the recent history of P...

We compare the mass functions obtained analytically, in the framework of an extended Press & Schechter (PS) formalism, in a previous paper to the numerical mass functions obtained in N – body simulations, using different algorithms to define objects in the density field. After discussing the properties of the algorithms, we show that the mass function obtained using the friend – of – friend alg...

To my family and good friends, both scattered around the World. Acknowledgments I would like to thank my mentor and thesis advisor, H.E. Stanley. Gene is an institution himself. A great scientist, a perfect advisor and a great friend. In the final version of this draft I will write a luxurious paragraph on him and the five years I spent at BU. I enjoyed so much in his research group. Unfortunat...

We study the problem of achieving cooperation between two self-interested agents that play a sequence of different randomly generated normal form games. The agent learns how much the opponent is willing to cooperate and reciprocates. We present empirical results that show that both agents benefit from cooperation and that a small number of games is sufficient to learn the cooperation level of t...
