"A collection of essays from scholars around the globe examining the ethical issues and problems associated with some of the major areas within contemporary international communication: journalism, PR, marketing communication, and political rhetoric"--

This study is a content analysis of the coverage of the war in Kosovo by three major American magazines - Time, Newsweek, and US News & World Report. American and independent international official documents show that the Kosovo conflict was a civil war between Kosovo's Serbian population supported by the Yugoslavian government and an Albanian nationalist terrorist organization (KLA). The main question of this study is: Did the American media tell this story correctly? The general hypothesis of this study was that the photo coverage of the war had been imbalanced with apparent bias against the Serbs. The hypothesis was statistically supported. A theoretical explanation for similar types of situations is offered in the discussion section. The author refers to this phenomenon as the media agitation mode and identifies eight main characteristics of such situations. The theory of supply and demand of political news is also introduced in this article.

To make causal inferences from observational data, researchers have often turned to matching methods. These methods are variably successful. We address issues with matching methods by redefining the matching problem as a subset selection problem. Given a set of covariates, we seek to find two subsets, a control group and a treatment group, so that we obtain optimal balance, or, in other words, the minimum discrepancy between the distributions of these covariates in the control and treatment groups. Our formulation captures the key elements of the Rubin causal model and translates nicely into a discrete optimization framework.
