This article explores the relations between a foreign aid donor and local actors in the context of the dissemination of development discourses and practices in an authoritarian context. It addresses the question “To what extent may the local dynamics alter the original goals of a donor and lead to unintended consequences?” Based on archival research, interviews, and secondary literature, this case study examines the Yunnan Uplands Management Project (YUM) in 1990–95, the Ford Foundation's first grant program on rural poverty alleviation in China. While the Foundation did not attain its main goal of making YUM a national model for poverty alleviation, the local actors were able to use YUM to develop individual capacities and to build roles for themselves as development actors in the form of associations and nongovernmental organizations, resulting in further support from the Foundation. The study contributes to our understanding of donor-local actor dynamics by highlighting the gaps between the original goals of a donor and the perspectives and motivations of local actors. The study suggests that local dynamics may influence the goals of donors and the ways they seek to disseminate development discourses and practices to local actors, despite the common conception of donors as hegemonic or culturally imperialistic.

The Anapa bay-bar is located in the northwestern part of the Black Sea. With the goal in mind to determine the short-term dynamics of the Anapa bay-bar we analyzed satellite images from 2003 to the present. Depending on the hydro-lithodynamical situation the shoreline configuration during storm can vary from a rectilinear to sinusoidal forms. There are regions of local erosion or accumulation whose formation is related to the alongshore motion of sediments and dynamics of underwater bars. Comparison of the data on 1965 and 1966 showed that in this period the amplitude of the shoreline position was more than 20 m but average displacement of the shoreline for 13 months was only 0.8 m. This study showed that for the analysis of changes in the shoreline position is necessary to consider the configuration of the coastline at the time of each observation and the local dynamics.

This chapter assesses transdisciplinarity as an epistemological and methodological approach to research and teaching in the emerging field of global studies. It posits that the world’s most pressing problems in the areas of migration, health, and intersectional identities, to name a few, are unlikely to be addressed convincingly by inquiries rooted exclusively in singular social science disciplines. At the same time, transdisciplinarity is understood as a means to complement disciplinary research, not to dispense with it. By foregrounding global–local dynamics and their effects across scales, global studies can draw from a wealth of approaches and experiences in interdisciplinary scholarship without becoming entangled in protracted epistemological battles over scholarly turf. This chapter then provides examples of transdisciplinary research in global studies and closes by stressing the importance of disciplinary methodological innovations as building blocks for multimodal designs and arguing for methodological rigor in global studies, whether transdisciplinary or not.

After the renewal of national independence in 1945 former anti-fascist partisans were among the Czechoslovak Communist Party's most reliable and radical allies. Nevertheless, following the communist coup of 1948, a group of partisans in the rural region of Moravian Wallachia began to mobilise wartime networks and tactics against the consolidating party dictatorship, establishing the Světlana resistance network. Simultaneously, state authorities also drew on partisan practices to reconstitute opposition and resistance in this region as evidence of an international conspiracy that could be understood and prosecuted within the framework of official ideology and propaganda. This article analyses the case of Světlana to examine the politics of people's democracy in Czechoslovakia and explore local dynamics of resistance and repression during the early years of the communist regime.

AbstractWe study coagulation equations under non-equilibrium conditions which are induced by the addition of a source term for small cluster sizes. We consider both discrete and continuous coagulation equations, and allow for a large class of coagulation rate kernels, with the main restriction being boundedness from above and below by certain weight functions. The weight functions depend on two power law parameters, and the assumptions cover, in particular, the commonly used free molecular and diffusion limited aggregation coagulation kernels. Our main result shows that the two weight function parameters already determine whether there exists a stationary solution under the presence of a source term. In particular, we find that the diffusive kernel allows for the existence of stationary solutions while there cannot be any such solutions for the free molecular kernel. The argument to prove the non-existence of solutions relies on a novel power law lower bound, valid in the appropriate parameter regime, for the decay of stationary solutions with a constant flux. We obtain optimal lower and upper estimates of the solutions for large cluster sizes, and prove that the solutions of the discrete model behave asymptotically as solutions of the continuous model.

Abstract Since its introduction from the West, social work has unprecedentedly developed in China in recent decades. Accordingly, existing definitions of social work became outdated quickly inevitably. Indigenisation offers a useful perspective for understanding the development of social work in the rapidly changing context of China. However, indigenisation is often regarded as a linear and unidirectional process of knowledge transfer and adoption from the West to third world countries, which easily results in local dynamics getting ignored. This article views indigenisation as the result of competition amongst different local stakeholders. By discussing social work in China presently and examining the performance of different stakeholders, we argue that Chinese social work differs from social work in the West to some extent, especially in terms of its professional value, which has been challenged. Finally, the article highlights the implications of China’s experience with social work for the international community.

It is a well-known fact that the Newtonian description of dynamics within Galaxies for its known matter content is in disagreement with the observations as the acceleration approaches a0≈1.2×10−10 m/s2 (slighter larger for clusters). Both the Dark Matter scenario and Modified Gravity Theories (MGT) fail to explain the existence of such an acceleration scale. Motivated by the closeness of the acceleration scale and the Hubble constant cH0≈10−9 h m/s2, we are led to analyze whether this coincidence might have a Cosmological origin for scalar-tensor and spinor-tensor theories by performing detailed calculations for perturbations that represent the local matter distribution on the top of the cosmological background. Then, we solve the field equations for these perturbations in a power series in the present value of the Hubble constant. As we shall see, for both theories, the power expansion contains only even powers in the Hubble constant, a fact that renders the cosmological expansion irrelevant for the local dynamics.
