Abstract Policymakers employ economic sanctions to deal with a wide range of international challenges, making them an indispensable foreign policy tool. While scholarship on sanctions has tended to focus on the factors affecting their success, newer research programs have emerged that explore the reasons for why sanctions are threatened and initiated, the ways they are designed and enforced, and their consequences. This scholarship has yielded a wealth of new insights into how economic sanctions work, but most of those insights are based on sanctions observations from the 20th Century. The ways that policymakers employ sanctions have fundamentally changed over the past two decades, though, raising concerns about whether historically derived insights are still relevant to contemporary sanctions policies. In this forum, the contributors discuss the scholarly and policy-relevant insights of existing research on sanctions and then explore what gaps remain in our knowledge and new trends in sanctions policymaking. This forum will inform readers on the state of the art in sanctions research and propose avenues for future research.

During the past two decades, critical infrastructures (CIs) faced a growing number of challenges worldwide due to natural disasters and other disruptive events. To respond to and handle these disasters and disruptive events, the concept of resilience was introduced to CIs. Particularly, many institutions and scholars developed various types of frameworks to assess and enhance CI resilience. The purpose of this paper is to review the resilience assessment frameworks of the CIs proposed by quality papers published in the past decade, determine and analyze the common dimensions and the key indicators of resilience assessment frameworks of CIs, and propose possible opportunities for future research. To achieve these goals, a comprehensive literature review was conducted, which identified 24 resilience assessment frameworks from 24 quality papers. This paper contributes to the current body of resilience research by identifying the common dimensions and the key indicators of the resilience assessment frameworks proposed for CIs. In addition, this paper is beneficial to the practice, because it provides a comprehensive view of the resilience assessment frameworks of CIs from the perspective of implementation, and the indicators are pragmatic and actionable in practice.

For international and domestic actors, postconflict situations constitute one of the most difficult policy arenas to understand and operate within. In this context, the sustainable management of natural resources to prevent conflict and build peace—before, during, or after conflict—has received increasing scholarly attention over the past three decades. Emphasizing the potential for environmental cooperation to support peace and stability, researchers have focused on the ecological foundations for a socially, economically, and politically resilient peace. This chapter takes stock of the current state of the art on environmental peacebuilding, providing a summary of the most common definitions before looking back at the development of environmental peacebuilding along the two most noticeable perspectives and the remaining challenges and pathways for future research.


Trust is one of the most classic themes across the social and behavioral sciences. It is also a topic is that is strongly intertwined with cooperation and social dilemmas, and there is little doubt that trust is an effective tool to promote cooperation, even if cooperation without trust is possible under certain circumstances. The past decade has also increasingly revealed emerging themes, new theoretical developments, intriguing questions, and a challenging debate revolving around the evolution, as well as strengths and limitations, of trust in social dilemmas and other situations of interdependence. Major societal issues are partially issues of trust: the financial crisis and the refuge crisis are two examples. Why can systems of excessive bonuses emerge and survive? Why is it that we tend to approach individuals with a healthy dose of trust, but we tend to be suspicious of other groups—or even individual members of other groups? Some scientists make the claim that it is ultimately trust—or rather the lack of it—that undermines intergroup relations. One of the next challenges is to examine the workings of trust and how best to organize a system that exploits the opportunities of trust within groups and between groups in contemporary society. We hope this book provides a state of the art of this literature and that the themes discussed in this book will indeed turn out to be prominent ones in future research on trust in social dilemmas—whether they operate at the level of interpersonal or intergroup relations.

Data-driven crowd modeling has now become a popular and effective approach for generating realistic crowd simulation and has been applied to a range of applications, such as anomaly detection and game design. In the past decades, a number of data-driven crowd modeling techniques have been proposed, providing many options for people to generate virtual crowd simulation. This article provides a comprehensive survey of these state-of-the-art data-driven modeling techniques. We first describe the commonly used datasets for crowd modeling. Then, we categorize and discuss the state-of-the-art data-driven crowd modeling methods. After that, data-driven crowd model validation techniques are discussed. Finally, six promising future research topics of data-driven crowd modeling are discussed.

Ketamine [2-(2-chlorophenyl)-2-(methylamino)cyclohexanone] is a dissociative anaesthetic, first developed in 1963 by Parke-Davis. It finds widespread application in the treatment of battlefield injuries, and in emergency departments for use in children. In recent times the clinical interest in ketamine has increased due to the positive impact it has in treating depression and the rapid onset of its antidepressant effect. This review covers the synthetic effort towards ketamine and related analogues over the past 60 years to give readers an overview of past, current, and future research outlook pertaining to ketamine-like molecules.1 Introduction2 Early Work3 Synthesis3.1 Ketamine3.2 Norketamine3.3 Ketamine Analogues4 Future Outlook and Conclusion

Autonomic service-driven applications represent a new realm of software that can discover new capabilities, automatically integrate with other systems, and adapt to changing system environmental conditions. For the past many years, researchers and practitioners have been investigating, prototyping, and evaluating these self-configuring, self-healing, self-optimizing, and self-protecting systems. Although validation is expected to play a key role in the success of autonomic systems, there are few works that address this topic. Dynamic adaptation in autonomic software results in structural and behavioral runtime changes, which cannot be validated offline at design-time. Runtime testing has therefore emerged as a possible solution to validating dynamic adaptations in autonomic software. This chapter summarizes the state-of-the-art in runtime testing of autonomic systems, describes key challenges associated with runtime testing, and provides guidelines for integrating runtime testing approaches into autonomic software using self-testing architectures. Finally, directions for future research for validation of autonomic components are discussed.

This article reports on the state of the art of artificial hands, discussing some of the field's most important trends and suggesting directions for future research. We review and group the most important application domains of robotic hands, extracting the set of requirements that ultimately led to the use of simplified actuation schemes and soft materials and structures—two themes that clearly emerge from our examination of developments over the past century. We provide a comprehensive analysis of novel technologies for the design of joints, transmissions, and actuators that enabled these trends. We conclude by discussing some important new perspectives generated by simpler and softer hands and their interaction with other aspects of hand design and robotics in general.
