Integrating the development of data mining and data warehouses via model-driven engineering

Data mining is one of the most important analysis techniques to automatically extract knowledge from large amount of data. Nowadays, data mining is based on low-level specifications of the employed techniques typically bounded to a specific analysis platform. Therefore, data mining lacks a modelling architecture that allows analysts to consider it as a truly software-engineering process. Bearing in mind this situation, we propose a model-driven approach which is based on (i) a conceptual modelling framework for data mining, and (ii) a set of model transformations to automatically generate both the data under analysis (that is deployed via data-warehousing technology) and the analysis models for data mining (tailored to a specific platform). Thus, analysts can concentrate on understanding the analysis problem via conceptual data-mining models instead of wasting efforts on low-level programming tasks related to the underlying-platform technical details. These time consuming tasks are now entrusted to the model-transformations scaffolding. The feasibility of our approach is shown by means of a hypothetical data-mining scenario where a time series analysis is required.

ICT in higher education: an experience with e-books

The present paper seeks to explain the diverse advantages of virtual books and also the main barriers that make it difficult their implementation in the classroom. A brief review of the literature on ICT, e-learning, distance education and e-books will be complemented with a case study about the preparation, development and implementation of an e-book. The paper could be helpful both for systems analysts and for teachers when they are developing and implementing e-books.

Two decades on from the break-up of Czechoslovakia: Departures, diversions and destinations. CEPS Commentary, 7 March 2013

Twenty years after the split of Czechoslovakia, expert analysts from the Czech Republic, Slovakia and the UK shed light on the political geography of this part of Central Europe in an extended three-part Commentary. The end points in the Euro-Atlantic integration processes of the successor states may be similar, argue the authors, but the journeys have been very different. Recent experience would suggest that in terms of EU politics, the Slovaks will be rather passive whilst the Czechs might be a little more troublesome. On the domestic front, the political discourse and competition in both states will largely revolve around the question of competence and corruption.

EEAS 2.0. A legal commentary on Council Decision 2010/427/EU establishing the organisation and functioning of the European External Action Service. EIPA Working Paper, 2013

From the Preface. Pursuant to Article 13(3) of Council Decision 2010/427/EU of 26 July 2010 establishing the organisation and functioning of the European External Action Service, the High Representative is held to provide a review of the organisation and functioning of the EEAS by mid-­‐2013. This review will cover, inter alia, the implementation of Article 6(6), (8) and (11), so as to ensure an adequate geographical and gender balance and a meaningful presence of nationals from all member states in the EEAS. If necessary, the review will be accompanied by appropriate proposals for the revision of the 2010 Council Decision (e.g., suggestions for additional specific measures to correct possible imbalances of staffing). In that case, the Council will, in accordance with Article 27(3) TEU, revise the Decision in light of the review by the beginning of 2014. This short and user-­‐friendly legal commentary on the 2010 Council Decision is the first of its kind and is intended to inform those involved in the review process and to serve as a reference document for practitioners and analysts dealing with the EEAS. This commentary is not an elaborate doctrinal piece, but rather a textual and contextual analysis of each article, that takes account of i) other relevant legal provisions (primary, secondary, international), ii) the process leading to the adoption of the 2010 Council Decision (i.e. travauxpréparatoires), iii) the preamble of the Council Decision, and iv) insofar as it is possible at this stage, early implementation. Wherever relevant, cross-­‐references to other provisions of the EEAS Council Decision have been made so as to tie in the different commentaries and ensure overall consistency.

Will the Transatlantic Trade and Investment Partnership be a game-changer? EU Centre Singapore Policy Brief No. 5, April 2013

In February 2013, US President Barrack Obama, European Council President Herman Van Rompuy and President of the European Commission José Manuel Barroso announced the decision to go for an ambitious and comprehensive trade and investment agreement between the US and the EU. To be called the Transatlantic Trade and Investment Partnership (TTIP), this agreement would lead to a new stage in the transatlantic relationship and be a much needed boost to the lacklustre economic recovery so far. Some analysts have even argued that TTIP would be a “game changer” – besides the economic gains, it would serve a bigger strategic purpose of promoting EU-US common objective to set higher standards of trade liberalisation, and thereby level the playing field in China and other key emerging markets. This policy brief examines the reasons behind the current push towards TTIP and the possible contents of such an agreement. It also discusses the possible obstacles to the realisation of TTIP, and at the same time, looks into what a successful conclusion of TTIP would mean for Asia and beyond.

Land, Labour and Capital Markets in European Agriculture: Diversity under a Common Policy. CEPS Paperback. October 2013

Well-functioning factor markets are an essential condition for the competitiveness and sustainable development of agriculture and rural areas. At the same time, the functioning of the factor markets themselves is influenced by changes in agriculture and the rural economy. Such changes can be the result of progress in technology, globalisation and European market integration, changing consumer preferences and shifts in policy. Changes in the Common Agricultural Policy (CAP) over the last decade have particularly affected the rural factor markets. This book analyses the functioning of factor markets for agriculture in the EU-27 and several candidate countries. Written by leading academics and policy analysts from various European countries, these chapters compare the different markets, their institutional framework, their impact on agricultural development and structural change, and their interaction with the CAP. As the first comparative study to cover rural factor markets in Europe, highlighting their diversity − despite the Common Agricultural Policy and an integrated single market − Land, Labour & Capital Markets in European Agriculture provides a timely and valuable source of information at a time of further CAP reform and the continuing transformation of the EU's rural areas.

Turkey after the start of negotiations with the European Union - foreign relations and the domestic situation, Part II. OSW Report, July 2008

The Centre for Eastern Studies has decided to embark on the project entitled 'Turkey after the start of negotiations with the European Union - foreign relations and the domestic situation' for two major reasons: the start of the accession negotiations between Ankara and the European Union in October 2005, and the significant part which Turkey plays in western Eurasia (the Caucasus, the countries in the basins of the Black and Caspian Seas, the Middle East and the Balkans) which We wish to present our readers our second report discussing Turkey's relations with Central Asia, the Caucasus and Russia, the aspect of Turkish foreign policy regarding the Black Sea, and the role of Turkey as a transit country for oil and gas from the Middle East and the Caspian regions. The evaluation of Turkey's standpoint and potential regarding the aforementioned issues is especially important, considering the tensions existing in Turkey's relations with the EU and the USA, as well as the West's increasing engagement in the Caucasus, Central Asia and Black Sea regions. In this process, Ankara may play the role of a significant ally for the West. However, it may just as readily play the role of its rival, who could co-operate with other countries and may seriously frustrate the implementation of the EU and US' goals. The Report was developed between autumn 2006 and autumn 2007, over which time the project participants searched for publicly available documents in Poland, Turkey, EU countries and the USA, and went on five research trips to Central Asia, Russia, Turkey and Caucasus, where they met local analysts, officials and researchers.

Turkey after the start of negotiations with the European Union - foreign relations and the domestic situation, Part I. OSW Report, June 2007

The start of accession negotiations between Ankara and the EU is vital for the future of both Turkey and the Union, including Poland as its member state, as well as for the geopolitical situation in Eurasia (the Black Sea region, Caucasus, Central Asia and the Middle East). Appreciating the significance of these issues, the Centre for Eastern Studies in early 2005 decided to launch a project entitled "Turkey after the start of negotiations with the European Union - foreign relations and the domestic situation". The goal of this project is to present, within the context of accession negotiations, Turkey's greatest internal challenges as well as Ankara's relations with its neighbour regions, the EU and the USA. This Report is the first of three which will be published as part of the project. The Report includes texts on Turkish-US relations since 2003, major political and social challenges on Turkey's path towards the EU and the current condition of the Turkish economy. The Report was developed between July 2005 and November 2006, over which time CES workers and associates searched for publicly available materials in Poland, Turkey and EU countries, and went on three research trips to Turkey, where they met local researchers, analysts, politicians and officials. The authors of the Report would like to express their gratitude to everyone who have shared their opinions with them, and to the Polish Embassy in Ankara, especially to Ambassador Grzegorz Michalski and Minister Andrzej Ananicz for their expert support and assistance in the authors' work on this Report. This Report does not present the official stance of the Polish government on the issues discussed therein; instead it reflects the personal views of its authors, who have made their best efforts to ensure that their work is reliable.

The natural resources deficit: the implications for German politics. OSW Commentary No. 46, 2011-02-08

Falling amounts of natural resources and the ‘peak oil’ question, i.e. the point in time when the maximum rate of extraction of easily-accessible oil reserves is reached, have been among the key issues in public debate in Germany on all levels: expert, business and – most crucially – the government level. The alarming assessments of German analysts anticipate a rapid shrinkage of oil reserves and a sharp rise in oil prices, which in the longer term will affect the economic and political systems of importer countries. Concerns about the consequences of the projected resource deficit, especially among representatives of German industry, are also fuelled by the stance of those countries which export raw materials. China, which meets 97% of global demand for minerals crucial for the production of new technologies, cut its exports by 40% in summer 2010 (compared to 2009), arguing that it had to protect its reserves from overexploitation. In 2009 the value of natural resources Germany imported reached €84 billion, of which €62 billion were spent on energy carriers, and €22 billion on metals. For Germany, the shrinkage of resources is a political problem of the utmost importance, since the country is poor in mineral resources and has to acquire petroleum and other necessary raw materials abroad1. In autumn 2010, the German minister of economy initiated the establishment of a Resources Agency designed to support companies in their search for natural resources, and the government prepared and adopted a national Raw Material Strategy. In the next decade the policy of the German government, including foreign policy, will be affected by the consequences of the decreasing availability of natural resources. It can be expected that the mission of the Bundeswehr will be redefined, and the importance of African states and current exporter countries such as Russia and China for German policies will increase. At the same time, Germany will seek to strengthen cooperation among importer countries, which should make pressure on resource-exporting states more effective. In this context, it can be expected that the efforts taken to develop an EU resource strategy or even a ‘comprehensive resource policy’ will be intensified; or at least, the EU’s energy policy will permanently include the issue of sourcing raw materials.

Multipolar myths and unipolar fantasies. Egmont Security Policy Brief No. 60, February 2015

Is the world becoming multipolar or will it remain unipolar? Analysts disagree, but it might be that this does not matter too much and that we better skip polarity terminology altogether.

China on Central-Eastern Europe: ‘16+1’ as seen from Beijing. OSW COMMENTARY NUMBER 166/15.04.2015

From the Introduction. In 2012, China approached the countries of Central-Eastern Europe (CEE) with a proposal concerning regional cooperation in the ‘16+1’ formula. According to Chinese analysts, the rationale behind this breakthrough decision was Beijing’s acknowledgment of the growing importance of the region’s states within the European Union as well as a partial elimination of the ideological differences which had hamstrung cooperation in previous years. It seems that the eurozone crisis may be perceived as the reason for the CEE states’ increased interest in developing their cooperation with China. These circumstances have opened a ‘window of opportunity’ which Beijing has decided to exploit to create a kind of bridgehead in the region which it could later use in its further economic expansion in Europe. Apart from opening the CEE region up for investments, the ‘16+1’ format was intended to facilitate the shaping of relations between China and the EU and to become a tool in building a positive image for China. Chinese experts agree that after three years of functioning, the ‘16+1’ regional cooperation format has helped Beijing achieve its goals only to a limited extent. The major obstacles have included: the immense diversification of the region, barriers related to EU law, insufficient expertise on the part of Chinese companies, the asymmetry of economic needs on both sides, and no willingness within the region itself to develop cooperation. Regardless of the limited effectiveness of activities carried out so far, China has continued its ‘16+1’ initiative. This continuation and the progressing institutionalisation of cooperation in the ‘16+1’ format have often seemed superficial. China has been using this multi-party formula to improve its long-term bilateral relations with selected states in the region and thereby to create a basis for Beijing’s political and economic presence in Central-Eastern Europe.

Analysis of developments in EU capital flows in the global context. Bruegel Final study Bruegel N° 2015.2574, November 2015

Free movement of capital, which is one of the four fundamental economic freedoms of the European Union, can enhance welfare if it leads to better allocation of financial and productive resources. However, it can also be a source of vulnerability, with far-reaching spillovers. Monitoring and assessing capital flows is therefore crucial for policymakers, market participants and analysts.

Between nuclear armament and economic pragmatism: Is North Korea facing change? Asia Policy Brief 2013/04, September 2013

The balance a year and a half after the meanwhile second hereditary power transfer to Kim Jong-Un (Kim Chŏng-ŭn), grandson of the founder of the state, is undecided. The breakdown of the system, predicted by many analysts, has not happened yet. Neither have the reforms that were expected from the young man who has supposedly been educated in Switzerland. The country is not in stagnation however – quite the opposite. What has happened in North Korea in the last two years? What development trends are there and how can other countries approach them? These questions are discussed in the light of the tense security-political and humanitarian environment and the corresponding risks in this Asia Policy Brief.
