ADHOCISM Dataset

Against the background of a crisis of United Nations (UN) peace operations, military ad hoc coalitions (AHCs) have increasingly gained a foothold as conflict management tools. This dataset, associated with the article \"Military Ad Hoc Coalitions and Their Role in International Conflict Management: Insights from the ADHOCISM Dataset,\" published in International Peacekeeping, offers the first comprehensive empirical mapping of 58 military AHCs since 1945. We map attributes of temporality, membership, organizational structure, geographical orientation and mandate, and show that military AHCs are not a new phenomenon, but that their composition and use have changed considerably over time. The ADHOCISM dataset makes comparative analysis possible among military AHCs, but also between them and other types of arrangements, such as UN peace operations or operations implemented by regional organizations. It offers much-needed data for scholars who wish to understand how the field of international conflict management is changing amidst a crisis of multilateralism and what role AHCs can perform in parallel with, or in replacement of UN peace operations.

在联合国（United Nations）维和行动陷入危机的背景下，军事临时联盟（military ad hoc coalitions, AHCs）作为冲突管理工具的地位日益巩固。本数据集关联发表于《国际维和》（International Peacekeeping）的论文《军事临时联盟及其在国际冲突管理中的作用：来自ADHOCISM数据集的洞察》，首次对1945年以来的58个军事临时联盟开展了全面的实证刻画。数据集涵盖了时间属性、成员构成、组织结构、地理定位与任务授权等核心维度，并揭示出军事临时联盟并非新兴现象，但其组成结构与应用方式随时间推移已发生显著变化。ADHOCISM数据集不仅支持军事临时联盟之间的比较分析，还可实现该类联盟与其他合作安排（如联合国维和行动或区域组织主导的行动）之间的对比研究。对于希望理解多边主义危机背景下国际冲突管理领域的演变趋势，以及军事临时联盟可在何种程度上协同乃至替代联合国维和行动发挥作用的学者而言，本数据集提供了亟需的研究数据。
