When an electric charge is supported at rest in a static gravitational field, its electric field is not supported with the charge, and it falls freely in the gravitationa field. Drawing the electric field lines continuously in time, we find that they always emerge from the charge, but the electric field is curved and there is a stress force between the freely falling (curved)field and the static charge. The charge radiates

This article considers how professionals \think by doing\and provides theoretical rationale for reflective practice as a model for teaching journalism. It presents a model focused on the development of graduate efficacy in the intellectual skills and understanding required of professional practitioners. The model uses critical reflection as a cognitive bridge between journalism theory and professional

This study examines the relationship between the extent of initial public offering (IPO) underpricing and market sentiment surrounding technology issues listing on the Australian Stock Exchange(AsX) during 1999 and 2000. We consider hype surrounding these issues as reflected in the media and as reflected in the market 's sentiment towards recent offerings by similar firms We also consider the relationship between technology firms' need for follow-on offerings due to

In the deliberations of scholars, policy analysts, and policy makers, power and influence. Yet the historical record shows that television has not changed the economics of attention not merely a fluke or just ironic. It points to a major impediment to the development of information societies. State-owned-and-controlled media can be an important policy lever for overcoming this opposition
