本文旨在探討第三者在談判中的角色，其究為斡旋者、調停者、仲裁者，或僅是信差 ？在何種環境下，應扮演何種角色，使用何種技術，較能促進談判成功？第三者對談 判的動機、利益與其干涉談判程度之關聯性如何？第三者對談判的功用如何？為了解 這些問題，乃以一九七七年至一九七九年以埃和談為個案，來看美國調停的情形與成 果，並藉以了解第三者在談判中的角色。 本文共分為七章。第一章導論，第一節中介紹研究架構、結構分析，以談判的價值、 議題、成員、陣營、實質及權力結構，自縱向來分析談判情形；第二節則探討有關第 三者在談判中角色之命題；第三節簡述以阿衝突之沿革。第二章至第六章為正文，依 美國干涉程度之改變，將一九七七年至一九七九年三月間之談判分為五個階段，各章 第一節敘述各階段歷史發展，第二節分析其價值與議題結構，第三結為權力結構之分 析，第四節則就成員、陣營、實質三結構分析，分別自橫向來看談判之進展與美國之 調停。第七章為結論。

The main objective of this thesis is to critically investigate and analyse the institutional role of the OAU in conflict resolution in Africa. In order to achieve that goal, among other things, it is argued that the philosophy, ideology and history of the Pan-African Movement influenced and shaped the institutionalisation process of the Pan-African Movement and the eventual establishment of the OAU, the formulation of its goals and objectives, as well as the OAU's potential in the resolution of conflicts on the continent. It is also argued on the one hand, that the tension between the preservation of sovereignty of the OAU member states, as well as their national interests and the promotion of continental interests on the other hand, directly affected the work of the OAU in conflict situations in Africa. Furthermore, it is emphasised in the thesis that the colonial legacy and the dynamics of the Cold War era did indeed affect the relations between the OAU member states and as a result, impacted on the African regional cooperation and the role of the OAU in conflict resolution processes in Africa. Another important aspect highlighted in the study was the evolution of the structures of the OAU involved in conflict management and resolution and their effect on the resolution of conflicts on the continent. A critical assessment was made of the various organs, mechanisms and methods adopted by the OAU and an attempt was made to ascertain whether they were suitable for the types of conflicts they were meant to resolve. Indeed, it is argued in the thesis that the principal organs of the OAU either lacked adequate powers to resolve inter-state conflicts, or they were inappropriately structured and thus they could not resolve these conflicts because their structures were not appropriate to intervene in most of these conflicts. Therefore, it can be stated that the mechanisms that were adopted by the OAU mediators to resolve these conflicts were not appropriate for the types of conflicts in which they were involved. It is important to mention that the conflict resolution mechanisms, which were provided for by the OAU Charter, were mainly aimed at resolving inter-state conflicts, and did not cater for various types of intra-state conflicts. An attempt was made in the study to ascertain to what extent this omission affected the role of the organisation in dealing with intra-state and other forms of conflicts, which emerged on the continent. Moreover, it is argued that the structural set up of the OAU's conflict resolution organs has produced complex legal and political problems for member states as well as to the parties to the conflicts. That situation in turn produced complex impediments in the operationalisation and the work of these organs in conflict resolution situations in Africa. This was because their functions were not distributed to minimise jurisdictual disputes such as boundary conflicts, hence resulting in the ineffectiveness of the work of the organisation. The study further analysed the extent to which the role and position of the UN as an international institution affected the role of the OAU in conflict management and resolution in Africa. The thesis also tried to ascertain to what extent the structural weaknesses and inherent challenges regarding the role of the UN in peace making in Africa hampered the work of the OAU in conflict situations where its cooperation with the UN was essential. Moreover, it is argued that the role and position of other regional organisations on the continent did in fact affect the role of the OAU in conflict management and resolution and that the inherent challenges and legal omissions of some vital provisions in the OAU charter regarding the role of the sub-regional organisations in peace-making in Africa did constrain the work of the OAU in conflict situations where its cooperation with sub-regional organisations was required. It was further argued that, although the American-European initiatives in conflict prevention, management and resolution in Africa was meant to facilitate and enhance the activities of the OAU in conflict situations in Africa, some of these initiatives did affect in different ways the role of the OAU. Finally, several arguments were presented to explain why the OAU was not able to successfully resolve the Ethiopian-Somali boundary dispute, a conflict seen as a typical inter-state dispute. Indeed, it is argued in the thesis that the Ethiopian-Somali boundary dispute exemplifies the challenges faced by and inherent weaknesses of the various mechanisms the OAU mediators had adopted to deal with conflict situations in Africa. / Political Science / D.

Balance-of-Power theory was tested by examining the 1977-1978 Ethiopian-Somali conflict and its outcome. The theory, according to Waltz (1979), claims to explain the international outcome arising from realpolitik or power politics, namely, the formation of balances of power. Given the close fit between the major developments leading to the eruption of conflict and the principal propositions of balance-of-power theory, the outcome of the conflict was expected to be consistent with that posited by the theory. This expectation was borne out by the study's finding which indicated that the conflict has produced a similar result. Confirmation of the theory was achieved by further subjecting the finding to the verification test established by Waltz.
