As part of a recent effort to bridge the studies of terrorism and civil war, new research has begun to emerge on the use of terrorism by rebel groups as a strategy of war. Building on these findings, we examine the role of affiliated political wings in shaping the use of terrorism by rebel groups during civil wars. We contend that the presence of an affiliated political wing during the civil war should increase the use of terrorism by rebel groups only in countries where there are relatively few restrictions on the freedom of the press. As political wings are often designed to engage with the civilian population through the dissemination of information, these apparatuses are in a key position to frame the use of terrorism as part of the rebel’s broader war effort. To test this proposition, we examine the use of terrorism by all rebel groups from 1970 to 2011. The results from the analysis provide strong support for our argument that political wings increase the use of terrorism by rebel groups only when the press is allowed to independently cover terrorist attacks.  相似文献

This article presents a detailed examination of some key political dimen- sions underlying cooperative research in agricultural biotechnology among state land-grant universities, state legislatures, and biotechnology corpora- tions. Factor analysis and path analysis methods are employed to assess differences in the perceptions of university administrators, biotechnology corporation researchers, and state legislators, using national and state survey data. Two attitudinal dimensions, one regarding cooperation among university and corporate researchers, and the other regarding barriers to joint research, are extracted. Generally similar attitudes are shared by university and legislative respondents, who are concerned over the prospects of market-oriented university research. In contrast, corporate respondents are more concerned with reducing barriers to cooperative research and the need for more open communication between academia and industry, and with issues of patent rights. Extensions of this work to other states and to other high-technology industries are considered.  相似文献
