BACKGROUND AND OBJECTIVES Fast-food companies have been reproached for rising obesity levels due to aggressive marketing tactics targeted at children. They have countered that parents should be held responsible considering their critical role as nutritional gatekeepers. This study examined the comparative effects of media exposure and parental mediation on Indonesian children's fast food consum...

Due to the recent proliferation of digital broadcasting, various schemes for broadcasting continuous media data have been studied. In general broadcasting systems, since data is broadcast repetitively, clients have to wait until their desired data is broadcast. These schemes reduce this waiting time by dividing the data into several segments of equal size. However, data often have appropriate d...

We consider information flow via physical transport of inscribed media through space and compare it to information flow via electromagnetic radiation. Somewhat counterintuitively for point to point links, physical transport of inscribed mass is often energetically more efficient by many orders of magnitude than electromagnetic broadcast. And perhaps more surprising, even in a broadcast setting ...

In this study, we designed and constructed a live media streaming system to broadcast important activities such as: graduation ceremonies, sport games, and banquets. There are many different streaming systems and coding formats. In this study, the selecting procedure would be conducted to find suitable and stable technology for implementing live broadcast service, and evaluate the feasibility o...

Social media platforms like Facebook, Twitter, and LinkedIn let people broadcast messages to their entire network of contacts all at once. As the number of users and the amount of information they broadcast grow, platform managers face an increasingly pressing problem – which broadcasts should they show their users? To address this question, I study the database of a social media company that s...

Streaming media is pervasive on the Internet now and is continuing to grow rapidly. Most streaming media systems have adopted the model of broadcast. Unfortunately, the nature of the broadcast-like one-to-many communication model is not able to foster interaction and collaboration among people. In this paper we discuss a community-oriented communication model for sharing streaming video and int...

The paper addresses the problem of solving classic distributed algorithmic problems under the practical model of Broadcast Communication Networks. Our main result is a new Leader Election algorithm, with O(n) time complexity and O(n lg(n)) message transmission complexity. Our distributed solution uses a special form of the propagation of information with feedback (PIF) building block tuned to t...
