ABSTRACTThe effects of organic cleaning agents (totally three) and degradation products from solid technical adsorbents (two) on the sorption of Eu on cement and TiO2 were measured with variation of concentration (0.001–10 % of the water phase for the cleaning agents, alkaline degradation products corresponding to 0.03–8 mM DOC for the adsorbents) and reaction time (up to 420 d). The effects of the cleaning agents Industrikombi and Prefect Citron were minor. The degradation of the ion exchanger (metaacrylic polymer) had no significant effect on the Eu-sorption. The other adsorbent (filter aid, inert fibre; acrylonitrile polymer) was rapidly degrading at high pH, and the degradation products had a significant reducing effect on the sorption of Eu at added DOC-levels in the mM-range. This category of adsorbent materials should not be incorporated in a cement waste matrix or be stored in a cementitious environment together with radionuclides.

Abstract This article develops the concept of the monopoly of jurisdiction of the Court of Justice of the European Union (CJEU) through the analysis of the case study of the Investment Court System (ICS). By providing a general framework over the criteria that have been developed by the Court, the work sheds light on the controversial principle of autonomy of the European Union (EU) and its implications to the EU’s external action. The work intends to be both pragmatic and analytical. On the one hand, the criteria are extracted as operative tools from the jurisprudence of the CJEU and then used in the context of the validity of the ICS. This provides the reader with some definitive standards that can then be applied to future cases whenever a question concerning autonomy arises. On the other hand, the article questions the reasons behind the idea of the monopoly of jurisdiction of the CJEU, advancing a concept of autonomy of the EU as a claim for power and critiquing the legitimacy and coherence of its foundations. Both dimensions will hopefully help to provide some clarity over the meaning of autonomy and the monopoly of jurisdiction, while, at the same time, promoting a larger discussion on its impact on the external action of the EU.

In an era of increased globalisation, the need for a sense of belonging and an identity is becoming more pressing. The way nations form images of others and, conversely, conscious or unconscious images of themselves is becoming increasingly important as these images impact on public opinion and on political and decision-making discourse. With the development of supranationalism in Europe, the age-old notion of European identity has come more and more to the fore. Conflicting interpretations and a general disinclination to consider the matter leave the notion of European identity as polysemic as ever. Furthermore, the expansion of the EU has contributed to blurring this notion, so much so that in the collective psyche, it has become closely linked to the membership of the European Union and it is proving sometimes difficult to dissociate one from the other. In this context, the debate surrounding Turkey’s membership of the EU gives an insight into prototypical and stereotypical representations of Europe. As the controversy has been particularly salient in France, the aim of this study is to explore the European self-conceptions and images of the other through the example of France’s opposition to Turkey’s membership of the EU. For this purpose, opinion polls and the Press will be used as forms of narrative in order to highlight these representations and how they have evolved in time. The first part of the study will concentrate on the arguments put forward to justify the opposition to Turkey joining the EU. The second part will then evaluate how the image of the other contributes to the prototypical representation French citizens have of Europe.

This article examines the impact of national borders on public discourses, based on a case study of the struggle surrounding Turkey’s application to join the European Union (EU). Comparing opinions, reasons and interpretation patterns in quality press commentaries about enlarging the EU beyond the Bosphorus, the article confirms the importance and robustness of national cleavages between the German and the French public spheres on the one hand and the British public sphere on the other. Whereas Turkish membership was predominantly rejected on the continent, the British commentators strongly and almost unanimously supported Ankara’s request. These similarities and divergences, I argue, are first and foremost the result of competing visions of Europe’s finality, especially regarding various constitutional ideas and cultural principles. Against this background, the Turkey question was partly exploited as an instrument to advance or to suppress different concepts on the future of European integration.

The primary goal of this book is to trace the European Commission’s strategies of dealing with the politicisation of EU legislation. In a case study on President Jean-Claude Juncker's term of office, the authors of this volume analyse how the EU Commission set and advanced certain political priorities between 2014 and 2019. The analysis focuses on the ten political priorities which the Juncker Commission retained in all of its annual work programmes from its inception onwards, starting with its self-proclaimed role as a ‘political commission’. However, this study’s assessment of the ‘politicisation’ of integration policy is ambiguous: On the one hand, the Juncker Commission deliberately adopted politicised issues and tried to use them as opportunities for political leadership as well as to hone its own institutional profile. On the other hand, controversies and crises repeatedly forced the EU Commission to resort to damage control.

Euroscepticism has become more and more embedded both at the EU and national levels (Usherwood et al. 2013) and persistent across domestic debates (Usherwood and Startin 2013). This study presents an in-depth analysis of contemporary narratives of Euroscepticism. It first introduces its question related to understanding public Euroscepticism, following the British EU referendum campaign and outcome, to then present the established literature, and the analysis of the British case study. A survey run in Britain in May 2019 shows that, as already noted by Oliver Daddow (2006, 2011), Euroscepticism is very much identifiable in the traditional narratives of Europe as the Other. Context accountability (Daddow 2006) is still cause for concern in Britain and by assuming a more positive view of a European Britain (Daddow 2006) does not make the debate more informed. Images, narratives and specific issues to reform the Eurosceptic toolbox into a more neutral, but informative, instrument could be applied at the grassroots level, as the post-referendum demonstrations and manifestations have shown. British citizens are reclaiming their own European citizenship, and deconstructing existing Euromyths can be a first small step forward.

As the concern for the welfare of elderly people is rather poor in our country, unlike the other countries in the EU, it is a legitimate priority to look for improvements of the situation. Therefore the paper aims at presenting a non-invasive and creative procedure that allows the assessment and helps the rehabilitation of elderly people who suffer various physical traumas and are also affected by other diseases like high blood pressure, osteoporosis, osteoarthritis, etc. A case study is developed as a model for other future assessments and procedures in order to open new opportunities for the improvement of elderly people life quality.

It is the aim of the present poster to show two approaches for assessing the influence of the alkaline degradation of cellulose on the sorption of tri- and tetravalent radionuclides. The two approaches differ in their degree of conservativity, one is a conservative, the other a realistic model case. The result of both examinations is expressed in terms of sorption reduction factors, valid for a situation where cellulose degradation products are influencing the sorption of radionuclides on cement.

This aims to review and analyze the Jordanian experiment in the developmental regional planning field within the decentralized managerial methods, which is considered one of the primary basic provisions for applying and success of this kind of planning. The study shoed that Jordan has passed important steps in the way for implanting the decentralized administration, but these steps are still not enough to established the effective and active regional planning. The study reveled that there are many problems facing the decentralized regional planning in Jordan, despite of the clear goals that this planning is trying to achieve. These problems have resulted from the existing relationship between the decentralized administration process’ dimensions from one side, and between its levels which ranged from weak to medium decentralization from the other side, In spite of the official trends aiming at applying more of the decentralized administrative policies, still high portion of these procedures are theoretical, did not yet find a way to reality. Because any progress or success at the level of applying the decentralized administrative policies doubtless means greater effectiveness and influence on the development regional planning in life of the residents in the kingdom’s different regions. So, it is important to go a head in applying more steps and decentralized administrative procedures, gradually and continuously to guarantee the control over any negative effects that might result from Appling this kind of systems.   © 2018 JASET, International Scholars and Researchers Association

Bu çalışmanın amacı, Türkiye’den göç ve Almanya’nın ekonomik göstergeleri arasındaki ilişkiyi, nicel metot yöntemleri kullanarak değerlendirmektir. Türkiye’nin belirsiz Avrupa ile bütünleşme beklentilerine rağmen  Avrupa Birliğinin köklü üyelerine olan Türk göçü devam edecektir. Çok sayıda Türk azınlığın yaşadığı ve hayat standartlarının yüksek olduğu Almanya, Hollanda ve Fransa’ya  büyük bir göç dalgası gerçekleşebilir. Çalışmanın istatistiksel bölümünün sonuçları, toplam göç ile gayri safi yurtiçi hasıladaki büyüme arasında pozitif, toplam göç ile işsizlik arasındaki negatif ve tahmin edilen bağımlılık yönüyle uygunluk içerisinde olan toplam göç ile aylık gelir arasında pozitif ilişki olduğunu göstermektedir. Türkiye’den göçle işsizlik arasındaki ilişki, toplam göçle olan ilişkiden daha düşüktür. Ancak, Almanya’daki yabancı mevcudiyeti ile Türkiye’den göç arasında bir ilişki bulunmaktadır. Bu durum, var olan göçmen topluluğunun olduğu yerin, yeni göçmenleri, köken bağlarına dayanarak cezbetmesi ve maliyet- riskler sebebiyle göçün düşük seviye de olduğuna dayanan kuramsal Ağ teorisi görüşü ile uygunluk göstermektedir. Göç ve işsizlik arasında gözlenen ilişki, Almanya’ya göçün  işgücü piyasasında talepte meydana gelen değişime karşılık geldiği gerçeğini göstermektedir. İşsizlik ve göç olgularının meydana geliş zamanlarında bir aralık  olsa bile  göç, Alman emek pazarında var olan dengesizliklerin azaltılmasında nispeten etkili bir mekanizma gibi görünmektedir. ENGLISH TITLE & ABSTRACTTurkish Immigration to the European Union: The Case of GermanyThe objective of the paper was to evaluate the relationships between immigration from Turkey and economic indicators in Germany using  quantitative methods. Despite Turkey’s unclear European integration prospects, it is predicted that Turkish immigration to  established member countries of the EU will continue. The strongest waves may flow to Germany, Netherlands or France, where numerous Turkish minorities are already present and where the living standards are high. Results from the statistical analysis of the paper showed a positive correlation between immigration total and the growth of gross domestic product. On the other hand, a negative correlation of immigration total and unemployment was found and a positive relationship between immigration total and income total which is in agreement with the expected dependency direction. With regards to  immigration from Turkey it is less correlated to unemployment than immigration total. But there is a correlation between immigration from Turkey and the stock of foreigners in Germany This is in accordance with the theoretical concept of network theory where an existing community of migrants keeps attracting new migrants because the costs and risks associated with migration are lower, thanks to established linkages to the country of origin. The observed correlation of migration and unemployment points to the fact that immigration to Germany responds to changes in demand in the labour market. Even though a time lag may occur in the case of unemployment and immigration, migration appears to be a relatively effective mechanism to offset existing imbalances in German labour markets.

There are many factors that can lead to internship satisfaction. Working environment is one of the factors that will result to such outcome. However, many organizations discarded the fact of its importance. The purpose of this study is to determine whether there is a significant relationship between working environment and internship satisfaction level as well as to determine whether the dimensions of working environment significantly affect internship satisfaction. The said dimensions are, learning opportunities, supervisory support, career development opportunities, co-workers support, organization satisfaction, working hours and esteem needs. A total of 111 questionnaires were distributed to the respondents and were processed by SPSS program to obtain the result of this study. The results reveal that learning opportunities, career development opportunities, organization satisfaction and esteem needs are factors that contribute to internship satisfaction level. In the other hand, supervisory support, co-workers support and working hours are factors that lead to internship dissatisfaction. The result also shows that organization satisfaction is the strongest factor that affects internship satisfaction while co-workers support is the weakest.
