We describe the design, implementation, and evaluation of Popcorn, a media delivery system that hides clients’ consumption (even from the content distributor). Popcorn relies on a powerful cryptographic primitive: private information retrieval (PIR). With novel refinements that leverage the properties of PIR protocols and media streaming, Popcorn scales to the size of Netflix’s library (8000 mo...

Over the years the fidelity and quantity of TV content has steadily increased, but consumers are still experiencing considerable difficulties in finding the content matching their personal interests. New mobile and IP consumption environments have emerged with the promise of ubiquitous delivery of desired content, but in many cases, available content descriptions in the form of electronic progr...

This study tests the proposition that peer influence mediates the effect of sensation seeking, a personality trait, on alcohol use among college students. Cross-sectional data to test this proposition were collected from a representative sample of college students at a large public northeastern university (N = 427). Results of hierarchical regression analyses showed that, as hypothesized, sensa...

This study assessed the speed of recognition of facial emotional expressions (happy and angry) as a function of violent media consumption. Color photos of calm facial expressions morphed to either an angry or a happy facial expression. Participants were asked to make a speeded identification of the emotion (happiness or anger) during the morph. Results indicated that, independent of trait aggre...

the idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. in addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. a useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...
