Role Theory in International Relations provides a comprehensive, up-to-date survey of recent theoretical scholarship on foreign policy roles and extensive empirical analysis of role behaviour of a variety of states in the current era of eroding American hegemony. Taking stock of the evolution of role theory within foreign policy analysis, international relations and social science theory, the authors probe role approaches in combination with IR concepts such as socialization, learning and communicative action. They draw upon comparative case studies of foreign policy roles of states (the United States, Japan, PR China, Germany, France, UK, Poland, Sweden, and Norway) and international institutions (NATO, EU) to assess NATO's transformation, the EU as a normative power as well as the impact of China's rise on U.S. hegemony under the Bush and Obama administrations. The chapters also offer compelling theoretical arguments about the nexus between foreign policy role change and the evolution of the international society. This important new volume advances current role theory scholarship, offering concrete theoretical suggestions of how foreign policy analysis and IR theory could benefit from a closer integration of role theory. It will be of great interest to all scholars and students of international relations, foreign policy and international politics.

How do you get students to engage in a historical episode or era? How do you bring the immediacy and contingency of history to life? Michael A. Barnhart shares the secret to his award-winning success in the classroom with Can You Beat Churchill? , which encourages role-playing for immersive teaching and learning. Combating the declining enrollment in humanities classes, this innovative approach reminds us how critical learning skills are transmitted to students: by reactivating their curiosity and problem-solving abilities. Barnhart provides advice and procedures, both for the use of off-the-shelf commercial simulations and for the instructor who wishes to custom design a simulation from scratch. These reenactments allow students to step into the past, requiring them to think and act in ways historical figures might have. Students must make crucial or dramatic decisions, though these decisions need not align with the historical record. In doing so, they learn, through action and strategic consideration, the impact of real individuals and groups of people on the course of history. There is a quiet revolution underway in how history is taught to undergraduates. Can You Beat Churchill? hopes to make it a noisy one.

Background In medical education, new technologies like Virtual Reality (VR) are increasingly integrated to enhance digital learning. Originally used to train surgical procedures, now use cases also cover emergency scenarios and non-technical skills like clinical decision-making. This scoping review aims to provide an overview of VR in medical education, including requirements, advantages, disadvantages, as well as evaluation methods and respective study results to establish a foundation for future VR integration into medical curricula. Methods This review follows the updated JBI methodology for scoping reviews and adheres to the respective PRISMA extension. We included reviews in English or German language from 2012 to March 2022 that examine the use of VR in education for medical and nursing students, registered nurses, and qualified physicians. Data extraction focused on medical specialties, subjects, curricula, technical/didactic requirements, evaluation methods and study outcomes as well as advantages and disadvantages of VR. Results A total of 763 records were identified. After eligibility assessment, 69 studies were included. Nearly half of them were published between 2021 and 2022, predominantly from high-income countries. Most reviews focused on surgical training in laparoscopic and minimally invasive procedures (43.5%) and included studies with qualified physicians as participants (43.5%). Technical, didactic and organisational requirements were highlighted and evaluations covering performance time and quality, skills acquisition and validity, often showed positive outcomes. Accessibility, repeatability, cost-effectiveness, and improved skill development were reported as advantages, while financial challenges, technical limitations, lack of scientific evidence, and potential user discomfort were cited as disadvantages. Discussion Despite a high potential of VR in medical education, there are mandatory requirements for its integration into medical curricula addressing challenges related to finances, technical limitations, and didactic aspects. The reported lack of standardised and validated guidelines for evaluating VR training must be overcome to enable high-quality evidence for VR usage in medical education. Interdisciplinary teams of software developers, AI experts, designers, medical didactics experts and end users are required to design useful VR courses. Technical issues and compromised realism can be mitigated by further technological advancements.

Coffee is one of the drinks that are consumed worldwide. The global coffee beans industry is currently facing several challenges, including The COVID19 pandemic’s long-term effects on their supply chains (SCs), adverse weather conditions affecting major coffee-producing regions, escalating price dynamics, and the increased in transportation costs. Jordan significantly relies on coffee imports, a critical agricultural product that constitutes an important part of local trade. Due to the lack of previous studies, the research aims to evaluate the current SC and improve Jordan’s coffee SC performance by reducing lead time and shipping cost. The research first uses the combined Fuzzy Analytic Hierarchy Process (FAHP) and The Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method to rank the supplier and choose the best suppliers based on established criteria. Then, the research proposes an analysis with the goal of enhancing the efficiency of Jordan’s coffee SC by applying Discrete Event Simulation (DES). Real company data is utilized to study, apply and evaluate the methodology used. The decision-making process employ decision makers and expert opinion input, providing a comprehensive and balanced evaluation of suppliers. Different scenarios are evaluated and compared based on the integrations of the FMCDM results in the simulation model. The findings identify the best and least favorable suppliers, highlighting Ethiopia’s leadership in several indicators. The outcomes suggest reducing lead time and shipping costs, investing in technology, and establishing a culture of continuous improvement to improve efficiency, stability, and adapt to market conditions. The research provides a comprehensive analysis of the current state of the coffee SC and suggests opportunities for development. Finally, recommendations to improve the current coffee SC in Jordan and directions for future research are discussed.

Due to the high cost of robots, the algorithm testing cost for physical robots is high, and the construction of motion control programs is complex, with low operation fault tolerance. To address this issue, this paper proposes a low-cost, cross-platform SCARA robot digital-twin simulation system based on the concept of digital twins. This method establishes a 5D architecture based on the characteristics of different platforms, classifies data and integrates functions, and designs a data-processing layer for motion trajectory calculation and data storage for a virtual-reality robot. To address the complexity of data interaction under different cross-platform communication forms, an editable, modular, cross-platform communication system is constructed, and various control commands are encapsulated into simple programming statements for easy invocation. Experimental results showed that, based on modular communication control, users can accurately control data communication and synchronous motion between virtual and physical models using simple command statements, reducing the development cost of control algorithms. Meanwhile, the virtual-robot simulation system, as a data mapping of the real experimental platform, accurately simulated the physical robot’s operating state and spatial environment. The robot algorithms tested using the virtual simulation system can be successfully applied to real robot platforms, accurately reproducing the operating results of the virtual system.

In Thailand, the populations of a commercially important crab Portunus pelagicus (Linnaeus, 1758) have been decreasing due to overfishing, raising concerns about the conservation efforts of this crab species. The Crab Bank Project has recently been established to restore crab populations by releasing crab larvae from each crab bank station. However, the fate of crab larvae after the release is poorly understood. Here, we assessed the dispersal and settlement patterns of the larvae P. pelagicus released from crab banks along the coast of Trang Province, Southern Thailand. The Lagrangian particle tracking model was employed to simulate the larval dispersal and settlement patterns after release from the crab banks during the inter-monsoon, southwest monsoon, and northeast monsoon. Our simulation revealed that virtual larvae were predominantly retained within inshore areas after the release for 14 days, regulated by tidal-driven currents, wind-induced currents, and local coastal topography. Monsoon periods affected the larval dispersal, with some larvae being transported into estuaries due to the SW monsoonal effects. After the 14-day release period, our modelled simulations suggested that the crab larvae arrived at numerous seagrass meadows along the coast, indicating potential settlement and growth. This result highlights the connectivity of sources and sinks for crab larvae after release from crab banks. Moreover, significant implications for conservation efforts and the fishery management of P. pelagicus were also discussed based on our modelled simulations.

Simulation-based education is a key aspect of health professions education used to aid healthcare providers in developing and maintaining clinical skills. Rural and remote healthcare providers have limited access to skills development opportunities. Training tools such as simulators are primarily limited to university and hospital-based research centers in urban areas. This scoping review aimed to examine current literature to identify a partnership model involving academic institutions and non-profit organizations (NPOs) that focuses on facilitating the wider distribution of simulators. The five-stage Arksey and O’Malley methodological framework for conducting scoping reviews and the Joanna Briggs Institute Manual for Evidence Synthesis was used to guide the scoping review. The search was conducted on five literature databases, three grey literature databases and through manual reference searching with an applied time frame of 2000 to 2022. The search identified 15 articles that met the eligibility criteria and were included in the study. Analysis of the articles revealed that no partnership model currently exists that facilitates the production and distribution of simulators through a partnership between academic institutions and NPOs. Establishing the partnership, acquiring funding, implementation, monitoring and evaluation, and dissemination were identified as key stages of a multi-institutional partnership. Further research is necessary to fill the gaps of the partnership process pertaining to the development and production of simulators to train healthcare providers.

This article presents ViEWS – a political violence early-warning system that seeks to be maximally transparent, publicly available, and have uniform coverage, and sketches the methodological innovations required to achieve these objectives. ViEWS produces monthly forecasts at the country and subnational level for 36 months into the future and all three UCDP types of organized violence: state-based conflict, non-state conflict, and one-sided violence in Africa. The article presents the methodology and data behind these forecasts, evaluates their predictive performance, provides selected forecasts for October 2018 through October 2021, and indicates future extensions. ViEWS is built as an ensemble of constituent models designed to optimize its predictions. Each of these represents a theme that the conflict research literature suggests is relevant, or implements a specific statistical/machine-learning approach. Current forecasts indicate a persistence of conflict in regions in Africa with a recent history of political violence but also alert to new conflicts such as in Southern Cameroon and Northern Mozambique. The subsequent evaluation additionally shows that ViEWS is able to accurately capture the long-term behavior of established political violence, as well as diffusion processes such as the spread of violence in Cameroon. The performance demonstrated here indicates that ViEWS can be a useful complement to nonpublic conflict-warning systems, and also serves as a reference against which future improvements can be evaluated.
