Terrorism as Transnational Advocacy: An Organizational and Tactical Examination

This article attempts to shed light on the dynamics and machinations within terrorist organizations by incorporating a heretofore overlooked literature which is directly applicable, that of transnational advocacy networks (TANs). Terror networks have been described using every possible analogy, from multinational corporations to organized crime to the anthropomorphic classic “cut off the head, and the body will die.” In reality, terrorist organizations function in much the same way, and using many of the same techniques, as transnational advocacy networks concerned with issues like the environment or human rights. By describing these characteristics, and comparing TANs and Terror TANs (TTANs), this article aims to offer insight into the tactics and motivations that define modern, as well as the much heralded post-modern, terrorism.     

Winning Coalition Formation in the U.S. Senate: The Effects of Legislative Decision Rules and Agenda Change

Recent empirical work has brought a renewed attention to the effect congressional rules of procedure have on the size of winning coalitions. Specifically, scholars have posited that legislative success hinges on the support of legislators identified by institutionally defined decision rules. Under these theories, supermajority decision rules in the U.S. Senate lead to larger, more inclusive coalitions on final passage. In this article, I reevaluate these claims by controlling for changes in the legislative agenda and the roll‐call voting record. I find that the aggregate size of winning coalitions is highly responsive to the underlying legislative agenda, the size of the Senate's majority party, and the manner in which researchers treat unrecorded votes. Further, my findings suggest that any connection between changes in the Senate's voting rules and the size of winning coalitions is spurious. Eric Schickler and Gregory J. Wawro have authored a response to this article, and Anthony J. Madonna has authored a rejoinder to this response. Both are available as Supporting Information .     

Al Shabaab's Foreign Threat to Somalia

This article focuses on the threat to Somalia by al Shabaab (The Youth), an extremist organization that controls most of southern and central Somalia. It learned its strategy and tactics from al Qaeda and the Taliban and relies heavily on a relatively small number of foreign fighters, most of whom are Somalis with foreign passports from the large Somali diaspora. The non-Somali contingent probably numbers only about 200 to 300, although it brings battlefield experience from Afghanistan and Iraq and provides al Shabaab with expertise in bomb making, remote-controlled explosions, suicide bombing and assassinations. Some of the foreigners occupy key positions in al Shabaab. The connection between al Shabaab and al Qaeda is growing stronger but has not yet reached the level of operational control by al Qaeda. Al Shabaab's draconian tactics, which are imported from outside and are anathema to most Somalis, and its foreign component may be its undoing.     

Commitment and Consequences: Reneging on Cosponsorship Pledges in the U.S. House

We argue that bill cosponsorship in Congress represents an institutional arrangement that provides credibility to commitments of support. We predict that if cosponsorship fosters legislative deals, MCs will only rarely back out on their pledges to support a bill if it comes up for a floor vote, and when they do, these choices will reflect strategic calculations. Further, legislators who violate their cosponsorship agreements will face punishment from colleagues, compromising their ability to gain support for their own bills. We explore the causes and effects of MCs' choices to renege on a pledge by voting no on a bill for which they were a cosponsor, focusing on all cosponsorship decisions in the 101st–108th Houses. The results reveal that patterns of reneging and its consequences are consistent with the idea that cosponsorship functions as a commitment mechanism.
