High-skilled Return Migration and Knowledge-based Development in Poland

It is by now well known that return migration of the highly skilled can have a significant impact on knowledge-based development in the regions to which they return. Whereas previous research has mainly focused on developing and newly industrializing countries, this paper looks at high-skilled return migration in an East European transformation economy, namely Poland. In our paper, we propose an analytical framework which integrates migration theory and regional development perspectives. Based on narrative interviews with high-skilled return migrants in Warsaw and Poznań, we show that high-skilled return migrants have an impact on economic development by acting as both investors and innovators, i.e. that they transfer and successfully integrate financial means as well as different types of knowledge into these local economies. Furthermore, the Polish example illustrates that social relations and institutional context are crucial in understanding how high-skilled return migrants contribute to knowledge-based development.     

Saami Circular Sacrificial Sites in Northern Coastal Sweden

Abstract

Saami circular sacrificial sites have been known for many years in northern Norway and northern interior Sweden. Oral or written sources regarding their origins are nevertheless lacking outside reindeer-herding areas. These circular features have now been documented in Swedish Bothnian coastal environments together with site complexes at elevations, suggesting that they were used during the Iron Age, medieval and historic periods. It is argued that these coastal features, stone circles or ring-shaped enclosures, are Saami sacrificial sites of the same character as documented in North Norway and in the mountains and the forest lands of northern Sweden.     

Affective politics and colonial heritage,Rhodes Must Fall at UCT and Oxford

ABSTRACT

The article analyses the spatial entanglement of colonial heritage struggles through a study of the Rhodes Must Fall student movement at the University of Cape Town and the University of Oxford. We aim to shed light over why statues still matter in analyzing colonial traces and legacies in urban spaces and how the decolonizing activism of the RMF movement mobilizes around the controversial heritage associated with Cecil Rhodes at both places – a heritage that encompasses statues, buildings, Rhodes scholarship and the Rhodes Trust funds. We include a comparative study of the Facebook use of RMF as it demonstrates significant differences between the two places in the development of the student movements as political activism. Investigating in more detail the heritage politics of RMF at UCT we fledge out what we call an affective politics using non-representational bodily strategies. We argue that in order for actual social movements to mobilize in current political controversies, they need to put affective tactics to use.     

Resilience unpacked – framing of ‘uncertainty’ and ‘adaptability’ in long-term flood risk management strategies for London and Rotterdam

Resilience is held as a promising concept to produce a paradigm shift from traditional flood control to an integration of flood risk management and spatial planning. Central ideas to the resilience narrative are that ‘nothing is certain except uncertainty itself’ and ‘adaptability’ is key to ‘governing the unknown’. However, this terminology is far from clear, yet increasingly used, which raises the question how it is made sense of in practice. To answer this question, we examine two long-term flood risk management strategies in the London and Rotterdam region with a policy framing perspective (i.e. the English Thames Estuary 2100 Plan and the Dutch Delta Programme). In both strategies, uncertainties are a key concern, leading to adaptive strategic plans. Reconstructing the framing processes shows that the English adopted a ‘scientific pragmatism’ frame and the Dutch a ‘joint fact-finding’ frame. While this led to different governance approaches, there are also striking parallels. Both cases use established methods such as scenario planning and monitoring to ‘manage’ uncertainties. Similarly to previous turns in flood risk management, the resilience narrative seems to be accommodated in a technical-rational way, resulting in policy strategies that are maintaining the status quo rather than bringing about a paradigm shift.     

Non-destructive fabric analysis of prehistoric pottery using high-resolution X-ray microtomography: a pilot study on the late Mesolithic to Neolithic site Hamburg-Boberg

The characterisation of prehistoric pottery fragments presents a quite complex task. In provenance studies, petrographic and chemical analyses of the ceramic materials are employed to investigate potential production areas in respect to the geolocial background. Moreover, also the production technology of the firing process, as well as the forming techniques used by the prehistoric potters are of great interest. Their investigation is most often accompanied by a destructive preparation of the samples. In this paper, we want to present high-resolution X-ray microtomography (μ-CT), a non-destructive and non-invasive method, as a supplementary research tool in the study of prehistoric pottery.     

A pilot study into the effects of X-ray and computed tomography exposure on the amplification of DNA from bone

This research investigates the intersection of radiography and aDNA, two commonly used methods in bioarchaeology. The goal of this project was to investigate the effects of radiation on the ability to amplify DNA from bone. Bones (n = 124) from domestic pig (Sus scrofa) feet were randomly sorted into a control group and four treatment groups: (1) single exposure X-ray; (2) single exposure CT; (3) multiple exposures X-ray; and (4) multiple exposures CT. Number of PCR cycles required to amplify DNA in 100 bp, 200 bp and 400 bp segments were used as a proxy for the amount of available DNA. In the 200 bp CT sample, distal phalanges required significantly more amplification cycles than did the other bones and were removed from analysis. Results suggest that in general radiation exposure fragments DNA thereby decreasing the amount that is amplifiable. While these results are suggestive, further research is required to elucidate the degree to which radiation fragments DNA in archaeological specimens.     

When open data and data activism meet: An analysis of civic participation in Cape Town,South Africa

Municipal open data projects are motivated by a desire to democratize data access and knowledge production, strengthen transparency, and advance cities socially and economically. However, their effects and implications are insufficiently analyzed. This paper examines civic engagement in open data in Cape Town, South Africa, the continent's first municipal-level open data initiative. Findings reveal how local civil society organizations have been driving engagement with municipal open data as part of their recent turn towards technology and data-driven forms of public engagement and activism. This analysis highlights the important role of the “smart civil society organization”—occupying a position between the smart city and smart citizen—that is developing significant capacity to produce and share data about the city's informal settlements with stakeholders in government, the private sector, and wider society. Minimal engagement with or recognition of civil society efforts illustrates the limits to the city's philosophy of data openness, which is largely restricted to releasing selected government datasets to the public. The notion of “bi-directional open data” is developed here to characterize emerging possibilities for data openness between governments and the public. This may be particularly relevant for cities like Cape Town with a highly active, capable, and data-literate civil society.     

?konomie in der EG-Wasserrahmenrichtlinie Erfolgskonzept oder unn?tige Herausforderung?

Die Integration ?konomischer Aspekte in die europ?ische Wasserpolitik und -bewirtschaftung gewann mit der EG-Wasserrahmenrichtlinie (WRRL) einen bedeutenden Impuls. Es ist die erste umweltpolitische Richtlinie auf europ?ischer Ebene, die explizit auf ?konomische Prinzipien – etwa das Verursacherprinzip –, Methoden wie die Kosteneffizienzanalyse und Instrumente wie beispielsweise die Wasserpreise zurückgreift, um ihre Ziele zu erreichen. Der Beitrag zieht eine erste Bilanz: Haben die ?konomischen Elemente der Richtlinie ihr Potenzial zur F?rderung eines effizienten Umsetzungsprozesses entfaltet oder sind sie (bislang) hinter den Erwartungen zurückgeblieben?
