政黨政治向來為研究憲政運作、民主深化的核心議題。過往的研究，多將政黨政治視為影響憲政與民主的自變項，但憲政特性以及民主轉型的過程，也可能系統性的影響政黨體系，對於政黨體系變遷的規模、機率，存在一定的關連性。基於此，本文以政黨體系變遷為依變數，從制度特性以及民主化背景來觀察政黨體系變遷的特性。核心假設有三：首先，就制度特性而言，直選總統的國家，比起議會內閣制的國家，政黨體系變遷的機率較高、規模較大；第二，以選舉時程而言，也是制度面向的因素，在直選總統的國家中，同時選舉或蜜月選舉，因為總統衣..

Party politics is an important issue to explain the constitutional work and consolidation of a democracy, and especially for newly democracies.

2011 年 5 月 2 日美國特種部隊攻擊賓拉登(Osama bin Laden)之住處並且結束長達十年對於頭號國際恐怖分子的追擊，在此之後，各國對於此事件的反應呈現出不同的面貌。本文將以實證方法研究美國與各國的外交關係、各國對賓拉登事件的反應、主要媒體評論之間的互動關連，整理出支持與不支持美國的總表。本研究亦將思考:在採取爭議性的方法達成其國家利益的同時，美國霸權是否可以在未來持盈保泰?本研究所採取的新聞分析方法，是否能夠提供外交政策研究更多的可能性? ..

As the U.S. special forces thundered into Bin Laden’s compound and terminated the decade long chase of the most wanted terrorist on May 2, 2011, the global reaction to this incident presented diverse versions for interpretation. This empirical study answers the questions: can the U.S. identify those who support or oppose its foreign policy by their reactions to the Bin Laden incident? By probing into the governmental archives and major media in selected countries, this research answers two more important questions: has ..
