There is growing attention to science diplomacy among scholars, policymakers, and scientific associations around the world. However, there continues to be contestation around the concept of science diplomacy, currently framed alternately as a new understanding of diplomacy, part of the global challenges discourse, central to the internationalization of science, and typifying competitive innovation. This contestation is furthered by the involvement of a broad array of policy instruments and actors in science diplomacy. In response, this paper focuses on a single policy instrument, examining eight bilateral and multilateral scientific cooperation agreements led by Canada, India, Norway, and the United Kingdom. Kingdon’s multiple streams framework is employed to explain how the interplay between policy actors, the policy agenda, policy problems, and policy alternatives leads to the creation of science diplomacy policies. Across the cases, all of the current science diplomacy discourses were applicable, holding stronger explanatory power in the problem and policy streams of the policy process while not obviously matching processes seen in the political stream. The findings also identified a gap in the current framing in understanding how geopolitical dynamics impact the creation of science diplomacy policies and how different policy actors negotiate, exploit, or are subject to these forces. By stabilizing one element of the ongoing debates around science diplomacy, the paper contributes a deeper examination of the array of policy actors and their involvement in different stages of the policy process leading to the formation of scientific cooperation agreements as tools of science diplomacy.
This study explored the identity management processes in interfaith marital communication in a United States setting. Sixteen marital partners participated in this interview study. Interviews were transcribed verbatim, interpreted, and analyzed. Guided by identity management theory, the interview data analysis revealed three general themes: development of the interfaith relational identity via the co-creation of a superordinate spiritual and value system; implementation of relational boundaries to prioritize the relational identity; and identification of key milestone decisions (i.e. wedding plans and children socialization coordination) interfaith partners face in their intimate relationships. Contributions, limitations, and directions for future studies on interfaith marital communication are addressed. 相似文献
As emerging technologies become increasingly inexpensive and robust, there is an exciting opportunity to move beyond general
purpose computing platforms to realize a new generation of K-12 technology-based learning environments. Mixed-reality technologies
integrate real world components with interactive digital media to offer new potential to combine best practices in traditional
science learning with the powerful affordances of audio/visual simulations. This paper introduces the realization of a learning
environment called SMALLab, the Situated Multimedia Arts Learning Laboratory. We present a recent teaching experiment for
high school chemistry students. A mix of qualitative and quantitative research documents the efficacy of this approach for
students and teachers. We conclude that mixed-reality learning is viable in mainstream high school classrooms and that students
can achieve significant learning gains when this technology is co-designed with educators. 相似文献
In this paper, we propose a feedback-based control approach to execute the time optimal motion trajectories for a differential drive robot. These trajectories are composed of straight lines and rotations in place. We show that the evolution of the position of a single landmark over time, in a local reference frame, makes it possible to track a prescribed time-optimal robot’s trajectory, based on feedback of the landmark’s position. We also show that the closed-loop system is an exponentially stable one with a nonvanishing perturbation, and that globally uniformly ultimately boundedness of the tracking errors can be achieved. The two main results of this work are: 1) Our approach leverages visual servo control type of methods with tools from optimal control for executing time-optimal trajectories in the state space based on feedback information. 2) The approach is able to work with the minimum number of landmarks–only one–this represents a necessary and sufficientcondition for landmark-based navigation. Experiments in a physical robot, a nonholonomic differential drive system equipped with an omnidirectional laser sensor, are shown, which validate the proposed theoretical modelling. 相似文献
We designed and used a series of activities (named activities to teaching electric field (ATEF)) based on the Physics by Inquiry (PBI) strategy to teaching the electric field concept with university students. We used a concentration factor tool to assess the effectiveness of those activities used during three weeks of instruction. Results indicate that students who had traditional teaching obtained a very tiny gain (less than 1%); concentration factors indicate that most of their responses fall into a random area, which is not favorable. On the other hand, the experimental group using our activities had greater gains (〉 10%) than the control group. Concentration factors showed that after instruction, students' mental models changed toward a favorable pattern about comprehension of electric field concept and Coulomb's law. A hypothesis test of two samples indicated that there is a significant difference between both traditional teaching and ATEF based on PBI. 相似文献
Teachers in U.S. schools report high rates of victimization, yet previous studies focus on select types of victimization and student perpetrators, which may underestimate the extent of the problem. This national study was based on work conducted by the American Psychological Association Classroom Violence Directed Against Teachers Task Force and is one of the few national studies to examine violence directed at teachers. Participants included 2,998 kindergarten through 12th‐grade (K‐12) teachers from 48 states who completed an anonymous web‐based survey assessing their experiences with victimization. Results revealed that 80% of teachers reported at least one victimization, and of these teachers, 94% reported being victimized by students. Nearly three‐fourths of all teachers experienced at least one harassment offense, more than half experienced property offenses, and 44% reported physical attacks. Findings suggest that specific teacher and community characteristics are associated with a higher likelihood of victimization, namely, male gender and urban settings; whereas, African American teachers were less likely to report victimization. Implications for teacher training, school interventions, public policy, and future research are discussed. 相似文献
Librarians in higher education who work in technical services must frequently rely on student employees to accomplish tasks previously assigned to professional staff. Hiring, training, managing, and mentoring student workers for the performance of high-level library functions can prove challenging. However, working side-by-side with student employees can be a positive experience when evidence-based training techniques and effective coaching and mentoring strategies are utilized. This article focuses on training techniques integrated with ongoing coaching and mentoring strategies to promote a positive work environment and motivated, successful student employees. 相似文献
