Linguistic diversity is complicated. It involves two main elements: a headcount of “languages”, plus variation and variability within and between them. In this article we show how language policy in Europe claims to protect diversity but falls short on these two measures. Our legal analysis examines the institutional politics of the European Union, details of accession, and institutionalisation of multilingualism. We describe the manifestation of a multilevel language hierarchy: working languages are topmost, then official languages, then non-official languages. This largely privileges national languages, principally English. Meanwhile allochthonous (‘immigrant’) languages are discounted, despite outnumbering autochthonous (‘indigenous’) languages. Our legal analysis therefore suggests an early stumble for linguistic diversity: even limited to a headcount of “languages”, most are neglected. Next, our sociolinguistic analysis examines the Council of Europe’s approach to protecting minority languages. We show how diversity can decline even among protected languages, using two case studies: Cornish, a young revival; and Welsh, an older, more established revival. The Cornish revival could only proceed after agreement on singular standardisation. Meanwhile the internal diversity of Welsh as declined significantly, fuelled by the normative reproduction of its standard form in education, and by sharpened social pressures against local dialects. Moreover, by comparing the EU and the Council of Europe, we aim for an overarching argument about “European language policy”. We conclude that linguistic diversity is neglected, through exclusion of most of the languages spoken in Europe, and pressures on language-internal diversity within protected languages. Linguistic diversity is something richer and more complex than the limited goals of existing policies; it transcends language boundaries, and may be damaged by planned intervention.
Technologies for the IoT have reached a high level of maturity, and a largescale deployment will soon be possible. For the IoT to become an economic success, easy access to all kinds of real-world information must be enabled. Assuming that not all services will be available for free, an IoT infrastructure should support access control, accounting, and billing. We analyze available access control and payment schemes for their potential as payment schemes in the IoT. In addition to security and privacy, we discuss suitability for direct client to sensor communication and efficiency.
We show shortcomings of existing protocols that need to be addressed by future research.
Reputation systems are useful to assess the trustworthiness of potential transaction partners, but also a potential threat to privacy since rating profiles reveal users’ preferences. Anonymous reputation systems resolve this issue, but make it difficult to assess the trustworthiness of a rating. We introduce a privacy-preserving reputation system that enables anonymous ratings while making sure that only authorized users can issue ratings. In addition, ratings can be endorsed by other users. A user who has received a pre-defined number of endorsements can prove this fact, and be rewarded e.g. by receiving a “Premium member” status. The system is based on advanced cryptographic primitives such as Chaum-Pedersen blind signatures, verifiable secret sharing and oblivious transfer.
The characteristics of creative educational interventions and the way they are implemented in the field often make their evaluation a challenging task. This article uses an exemplary intervention from a large-scale consumer education program on climate protection to present the design, method, and results of a two-step evaluation procedure which allows evaluators to cope with such a situation. Step 1 aims to answer the question of whether or not an intervention actually has the intended effects. Step 2 then assesses the factors that contribute to those effects. Thus, such a two-step evaluation yields information, not only on which interventions are effective and should therefore be maintained, but also on how they should be designed to achieve maximum effects.
Although the Council of Europe has been working in the area of administrative law for decades, the body of pan-European general principles of good administration developed by this organisation remains mostly uncharted. This paper attempts to help fill this academic gap by examining the scope and content of the pan-European principles of administrative law stemming from the Council of Europe, with a special emphasis on the principle of good administration. In doing so, the sources of administrative law of the Council of Europe are considered together with the mechanisms by which they penetrate and permeate domestic legal systems. This paper concludes that the work done by the Council of Europe in the administrative field has contributed to a process of harmonisation in its Member States’ domestic law, but that the exact scope thereof has yet to be uncovered and requires further research.
Administrative and Security Challenges of Germany's Refugee Crisis: an Explorative Assessment

Vortrag gehalten auf der CES Konferenz 2017 in Glasgow zum e-government in der europäischen Zollunion.
The European Union adopts rules governing the protection of minors against harmful media content in the form of soft law. Using the example of media law and the theory of competition between legal orders, I try to shed light on the possible reasons for the regulatory choice of soft law. In the present paper, I propose that one important reason for the preponderance of soft law in a given policy area is the legislator’s ambition to bridge strongly converging policy fields with areas where diversity between Member States persists due to their varying cultural traditions and moral convictions.

Governments and energy operators are frequently confronted with opposition to the construction of new energy infrastructure and a lack of public support. This is also true for the planning of new high-voltage overhead transmission lines. In this context, a question of interest for policy makers and energy operators is how residents react when they realize that they may be affected by future transmission lines in close proximity to their homes. This study provides evidence of how local residents respond to the announcement of transmission line corridor route alternatives (TLCRAs). By means of a natural experiment, it estimates the causal effects of spatial proximity to proposed TLCRAs during the planning phase of an energy project. The results reveal that proximity significantly enhanced residents’ risk perceptions with respect to landscape deterioration, property/house value reduction, and damages to human health. We also found that increasing proximity decreased residents’ support for grid expansion and increased the likelihood of performing information seeking behavior and becoming a member of a local citizens’ initiative. Finally, our findings suggest that the relationship between spatial proximity and the dependent variables are appropriately modeled by a distance decay function, showing that effects attenuate with increasing distance from the infrastructure site.

Higher education in both Germany and the UK has undergone numerous changes in the last two decades. It seems worthwhile to examine how varying forms of HE governance and pan-European influences have played out upon these two national systems. Of note in particular are Bologna, European Standards and Guidelines in Quality Assurance, and various accreditation regulations. In this article we postulate to what extent these two systems may or may not be able to move forward in the imminent future. Is German higher education, for example, becoming more autonomous if it can display its own systems of quality control are working well (system-accreditation)? Has British higher education relinquished autonomy, as both research and teaching domains are subject to external review (REF/TEF)? What can we learn about the transformational impact any of these mechanisms are having? This chapter adresses these issues and asks which benefits or disadvantages are to be gained by different systems in article.

The function and role of legal expert at ministry level of European states is very different. The following considerations focus on two major states of central European administration style, France and Germany.
With Home Automation Systems steadily gaining popularity and affordability, the threat of attacks on these installations is increasing.
Previous research has shown that passive adversaries can obtain considerable amounts of information about the users' habits and about how they interact with their system. Although encryption and other measures to ensure condentiality in communication are becoming a standard, traffic analysis remains an unsolved problem. In this paper, we take a look at different research areas and show that existing solutions cannot be easily applied to this scenario. However, we establish a model for traffic analysis in Home Automation Systems which leverages existing research on Private Information Retrieval. Using this model, both attacks and countermeasures can be analysed and their effectiveness can be measured to yield comparable results. We also take a look at legal aspects, highlighting problem areas and recent developments in the interaction between technology such as Home Automation and legislature.
