Abstract The use of ethnography for theological inquiry is no longer novel. Yet, as the introduction to this special issue indicates, the ethnographic turn in Christian theology is animated by distinct postliberal and liberationist trajectories, each with their own theological presumptions and methodological aims. Should the future development of this turn favour one trajectory over another? This paper explores this question in conversation with Todd Whitmore’s Imitating Christ in Magwi: An Anthropological Theology. Through a sustained engagement with Imitating Christ in Magwi, I unearth both postliberal and liberationist inheritances to show that Whitmore’s text exceeds a postliberal-liberationist binary. I then ask what the dual inheritance of his work signifies for the future of the ethnographic turn. Drawing from cultural anthropology’s mode of ‘studying up,’ I suggest that the turn should orient itself more broadly to the care of our common life by expanding attention to subjects with power.

The article examines the state of the Holocaust historiography in Ukraine for the period of 2010 – beginning of 2014. The review analyzes activities of major research and educational organizations in Ukraine which have significant part of projects devoted to the Holocaust; main publications and discussions on the Holocaust in Ukraine, including publications of Ukrainian authors in academic European and American journals. The article illustrates contemporary tendencies and conditions of the Holocaust Studies in Ukraine, defines major problems and shows perspectives of the future development of the Holocaust historiography in Ukraine.

This paper,first presented on 21 October 1995 at ajoint seminar ofthe Scottish Law Commission and the Faculty of Law, University of Edinburgh, on the subject of breach of contract, considers the future development of the law in this area, first by considering its history and current state in comparative terms and drawing the conclusion that it is characterised by a mixture of Civilian and Common Law elements; second, by comparing Scots law with the provisions on breach contained in recently published proposals for a harmonised law of contract (the UNIDROIT Principles of International Commercial Contracts, the Principles of European Contract Law prepared by the Lando Commission, and the draft “code”for the United Kingdom prepared on behalf of the English Law Commission by Harvey McGregor in the late 1960s) and in international conventions on the sale of goods. Although Scots law emerges reasonably wellfrom this exercise, there are a number of points to be taken on board in any future reform, as well as some insights into important underlying principles.

A practical and concise total synthesis of tricyclic ketone 7 (CDE ring), a valuable intermediate for the synthesis of racemic camptothecin and analogs, was described (8 chemical steps and 29% overall yield). The synthesis starts with two inexpensive, readily available materials and is operationally simple to perform. It is worth mentioning that the reported protecting group-free synthesis, with advantages of a short route, would be helpful for the future development of industry-scale syntheses of camptothecin-family alkaloids.

Environmental problems such as air pollution and greenhouse gas emissions are especially challenging in urban areas. Electric mobility in different forms may be a solution. While in recent years a major focus was put on private electric vehicles, e-mobility in public transport is already a very well-established and mature technology with a long history. The core objective of this paper is to analyze the economics of e-mobility in the Austrian capital of Vienna and the corresponding impact on the environment. In this paper, the historical developments, policy framework and scenarios for the future development of mobility in Vienna up to 2030 are presented. A major result shows that in an ambitious scenario for the deployment of battery electric vehicles, the total energy demand in road transport can be reduced by about 60% in 2030 compared to 2018. The major conclusion is that the policies, especially subsidies and emission-free zones will have the largest impact on the future development of private and public e-mobility in Vienna. Regarding the environmental performance, the most important is to ensure that a very high share of electricity used for electric mobility is generated from renewable energy sources.
