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持续过渡和振荡。 战争，公司，社会，市场或人类很少长期保持稳定，可预测的状态。 随机性，权力定律和人类行为可确保未来既未知又具有挑战性。 事件如何展开？ 他们什么时候抓住？ 为什么一些初始事件会导致雪崩，而另一些则不会？ 这些事件的特征是什么？ 有哪些阈值将海与非事件的变化区分开来？ 事实证明，复杂的自适应系统（CAS）方法是探索这些和其他相关现象的强大工具。 我们的目标是将来自CAS的工具和技术研究复杂系统的不同领域的研究人员和学生聚集在一起。 我们将重点介绍各个学科中的阈值效应，这是揭示在这些领域中发现的共同动态的途径。 智力优点。自25年前的成立以来，CAS作为一门学科的发展壮大。 然而，尽管CAS具有固有的跨学科性质，但在每个学科中都以“ stovepipe”的方式发展。 在自然，物理和社会科学方面非常需要增加协作和对话。 我们为建立一个基于广泛的研究人员和学生社区的努力通过将各种各样的组织者和参与者汇集在一起​​来满足这一需求。 该特定的研讨会着重于阈值效应 - 复杂系统中的非线性动态 - 作为鼓励跨学科对话的途径。 更广泛的影响。该研讨会是建立更广泛的CAS研究人员社区的重要步骤。 重要的是，不仅为年轻的研究人员和学生提供一个互相互动的论坛，而且要向在各自领域具有丰富经验的人那里学习。我们的研讨会对于学生与代表广泛学科和机构的人建立联系特别有用。
