Most interesting phenomena in natural and social systems include constant transitions and oscillations among their various phases. Wars, companies, societies, markets, or humans rarely stay in a stable, predictable state for long. Randomness, power laws, and human behavior ensure that the future is both unknown and challenging. How do events unfold? When do they take hold? Why do some initial events cause an avalanche while others do not? What characterizes these events? What are the thresholds that differentiate a sea change from a non-event? The Complex Adaptive Systems (CAS) method has proven to be a powerful tool for exploring these and other related phenomena. Our goal is to bring together researchers and students from diverse fields who study complex systems using the tools and techniques of CAS. We will highlight threshold effects in various disciplines as one avenue towards uncovering common dynamics that are found in these domains. Intellectual Merit. CAS as a discipline has grown tremendously since its inception nearly 25 years ago. Yet, despite its inherent interdisciplinary nature, CAS has grown in a "stovepipe" fashion within each discipline. There is a great need for increased collaboration and dialogue across the natural, physical, and social sciences. Our efforts to build a broad-based community of researchers and students addresses this need by bringing together a diverse set of organizers and participants. This particular symposium focuses on the threshold effect -- non-linear dynamics in complex systems -- as one avenue to encourage a cross-disciplinary conversation. Broader Impact. This symposium represents an important step for building a broader community of CAS researchers. It is important to not only provide a forum for young researchers and students to engage with each other, but also to learn from those with deep experience in their respective fields. Our symposium will be particularly useful for students to make connections with people who represent a broad range of disciplines and institutions.

自然和社会系统中最有趣的现象包括各个阶段之间的不断转变和振荡。 战争、公司、社会、市场或人类很少能长期保持稳定、可预测的状态。 随机性、幂律和人类行为确保未来既未知又充满挑战。 事件如何展开？ 他们什么时候站稳脚跟？ 为什么一些初始事件会导致雪崩，而另一些则不会？ 这些事件有何特点？ 区分巨大变化和非事件的阈值是什么？ 复杂自适应系统 (CAS) 方法已被证明是探索这些现象和其他相关现象的强大工具。 我们的目标是将来自不同领域的研究人员和学生聚集在一起，使用 CAS 的工具和技术研究复杂系统。 我们将强调各个学科中的阈值效应，作为揭示这些领域中常见动态的一种途径。 智力优点。自近 25 年前成立以来，CAS 作为一门学科取得了巨大的发展。 然而，尽管 CAS 具有固有的跨学科性质，但它在每个学科中都以“烟囱”的方式发展。 非常需要加强自然科学、物理科学和社会科学领域的合作和对话。 我们致力于建立一个基础广泛的研究人员和学生社区，通过汇集不同的组织者和参与者来满足这一需求。 这次特别的研讨会重点关注阈值效应——复杂系统中的非线性动力学——作为鼓励跨学科对话的一种途径。 更广泛的影响。本次研讨会是建立更广泛的 CAS 研究人员社区的重要一步。 重要的是，不仅要为年轻研究人员和学生提供一个相互交流的论坛，而且要向在各自领域拥有丰富经验的人学习。我们的研讨会对于学生与代表广泛学科和机构的人士建立联系特别有用。
