Educational transfer: Analytical frameworks, conceptualisations and motives

Educational transfer is an important and growing body of literature in the field of comparative education. Work from the last decade has focused on the stages of the borrowing cycle, and the context, cause and rationale for education borrowing. This recent work has contributed to earlier research on the role of multilateral organizations such as UNESCO, the OECD or the World Bank in education development and transfer. This paper provides an overview of current work on educational transfer, focusing on analytical framework, conceptualisations and motives. In doing so, the authors deliberately link related literature from different disciplines and perspectives to account for education policy changes. Rather than describing the substance, agents or mechanisms of educational transfer, the paper takes an analytical approach at a higher level of abstraction by asking questions such as: What are the domain's major dimensions or sub- domains in terms of methodology and theoretical perspective? What are the strengths or weaknesses of each dimension? What topics have yet to receive attention? What conceptual models are likely to be useful in guiding next steps in the study of educational transfer? Based on the systemisation, the authors then try to chart the way forward in the domain of educational transfer research

Calculation of the Coherent Synchrotron Radiation Impedance from a Wiggler

Most studies of Coherent Synchrotron Radiation (CSR) have only considered the radiation from independent dipole magnets. However, in the damping rings of future linear colliders, a large fraction of the radiation power will be emitted in damping wigglers. In this paper, the longitudinal wakefield and impedance due to CSR in a wiggler are derived in the limit of a large wiggler parameter $K$. After an appropriate scaling, the results can be expressed in terms of universal functions, which are independent of $K$. Analytical asymptotic results are obtained for the wakefield in the limit of large and small distances, and for the impedance in the limit of small and high frequencies.Comment: 10 pages, 8 figure
