News You Can Use or News That Moves?

This study investigates how journalists covering international humanitarian crises make decisions regarding what types of information to include in stories. Specifically, the inclusion/exclusion of solutions-oriented information is addressed, since crises represent a key time during which the potential for international engagement is discussed in the mainstream media. Interviews with journalists covering hunger crises in Africa reveal an internal tension between maintaining a neutral, unbiased position and writing in a way that supports engagement and action. Ironically, perhaps, journalists find that including solutions-oriented information amounts to unethical and biased coverage, despite the fact that inclusion of solutions to social problems is an accepted and institutionalized aspect of the US news media’s mandate to the public. Reasons for this seeming contradiction are discussed, and I argue that solutions-oriented information not only can be included without demonstrating bias, but that it ought to be included to support ethical coverage that properly informs citizens about potential paths for political engagement.

DC steady-states analysis of lossy uniform transmission lines

1 Introduction In the past 20 years with the rapid development of VLSI (very large scale integration) circuits and continual spread of electric power system scale, theories on transmission lines have become an important research field where finding the analytic solutions to lossy transmission line equations remains a tough nut. Since the mathematical tool cannot provide effective help, there is no universal method to solve transmission line equations [1]. A number of researchers have obtaine…
