This paper studies the change-point problem for a general parametric, univariate or multivariate family of distributions. An information theoretic procedure is developed which is based on general divergence measures for testing the hypothesis of the existence of a change. For comparing the exact sizes of the new test-statistic using the criterion proposed in Dale (J R Stat Soc B 48–59, 1986), a simulation study is performed for the special case of exponentially distributed random variables. A complete study of powers of the test-statistics and their corresponding relative local efficiencies, is also considered.

A procedure is proposed to name new chemical elements. After the discovery of a new element is established by the joint IUPAC-IUPAP Working Group, the discoverers are invited to propose a name and a symbol to the IUPAC Inorganic Chemistry Division. Elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist. After examination and acceptance by the Inorganic Chemistry Division, the proposal follows the accepted IUPAC procedure and is then ratified by the Council of IUPAC. This document is a slightly amended version of the 2002 IUPAC Recommendations; the most important change is that the names of all new elements should have an ending that reflects and maintains historical and chemical consistency. This would be in general “-ium” for elements belonging to groups 1–16, i.e. including the f-block elements, “-ine” for elements of group 17 and “-on” for elements of group 18.

A novel procedure for the preparation of solid Pd(II)-based catalysts consisting of the anchorage of designed Pd(II)-complexes on an activated carbon (AC) surface is reported. Two molecules of the Ar–S–F type (where Ar is a plane-pyrimidine moiety, F a Pd(II)-ligand and S an aliphatic linker) differing in F, were grafted on AC by π–π stacking of the Ar moiety and the graphene planes of the AC, thus favouring the retaining of the metal-complexing ability of F. Adsorption of Pd(II) by the AC/Ar–S–F hybrids occurs via Pd(II)-complexation by F. After deep characterization, the catalytic activities of the AC/Ar–S–F/Pd(II) hybrids on the hydrogenation of 1-octene in methanol as a catalytic test were evaluated. 100% conversion to n-octane at T = 323.1 K and P = 15 bar, was obtained with both catalysts and most of Pd(II) was reduced to Pd(0) nanoparticles, which remained on the AC surface. Reusing the catalysts in three additional cycles reveals that the catalyst bearing the F ligand with a larger Pd-complexing ability showed no loss of activity (100% conversion to n-octane) which is assigned to its larger structural stability. The catalyst with the weaker F ligand underwent a progressive loss of activity (from 100% to 79% in four cycles), due to the constant aggregation of the Pd(0) nanoparticles. Milder conditions, T = 303.1 K and P = 1.5 bar, prevent the aggregation of the Pd(0) nanoparticles in this catalyst allowing the retention of the high catalytic efficiency (100% conversion) in four reaction cycles.

A new interview procedure is proposed for collecting valid information on the acquisition of high-level performance in sport. The procedure elicits verifiable information on the development of athletes' achievements in their primary sport, as well as factors that might influence performance, including involvement in other sporting activities, injuries, physical growth and quality of training resources. Interviewed athletes also describe their engagement in specific training and other relevant activities during each year of their development as well as how they experienced each type of activity. The collected information is then examined to identify those aspects of the athletes' recall of their development that meet criteria of reliability and validity. Recommendations to coaches and scientists are discussed for how retrospective interviews can uncover aspects of development that distinguish elite from less accomplished athletes.

Introduction. Unintended as it was, the European Court of Justice (ECJ, the Court, the Court of the EU) has played an extremely important role in the construction of the Area of Freedom Security and Justice (AFSJ). The AFSJ was set up by the Treaty of Amsterdam in 1997 and only entered into force in May 1999. The fact that this is a new field of EU competence, poses afresh all the fundamental questions – both political and legal – triggered by European integration, namely in terms of: a) distribution of powers between the Union and its Member States, b) attribution of competences between the various EU Institutions, c) direct effect and supremacy of EU rules, d) scope of competence of the ECJ, and e) extent of the protection given to fundamental rights. The above questions have prompted judicial solutions which take into account both the extremely sensible fields of law upon which the AFSJ is anchored, and the EU’s highly inconvenient three-pillar institutional framework.1 The ECJ is the body whose institutional role is to benefit most from this upcoming ‘depilarisation’, possibly more than that of the European Parliament. This structure is on the verge of being abandoned, provided the Treaty of Lisbon enters into force.2 However spectacular this formal boost of the Court’s competence, the changes in real terms are not going to be that dramatic. This apparent contradiction is explained, to a large extent, by the fact that the Court has in many ways ‘provoked’, or even ‘anticipated’, the depilarisation of its own jurisdictional role, already under the existing three-pillar structure. Simply put, under the new – post Treaty of Lisbon – regime, the Court will have full jurisdiction over all AFSJ matters, as those are going to be fully integrated in what is now the first pillar. Some limitations will continue to apply, however, while a special AFSJ procedure will be institutionalised. Indeed, if we look into the new Treaty we may identify general modifications to the Court’s structure and jurisdiction affecting the AFSJ (section 2), modifications in the field of the AFSJ stemming from the abolition of the pillar structure (section 3) and, finally, some rules specifically applicable to the AFSJ (section 4).

In this new Policy Brief, CEPS Director Daniel Gros argues that the 13 November announcement of the European Commission that Germany is running an excessive current account surplus appears to be much ado about little. All the Commission can, and will, do is to start an ‘in depth analysis’. This might lead to strong political reactions and an enormous echo in the media. But nothing of concrete substance is likely to follow.

This CEPS Special Report analyses the composition of the 20 committees in the new European Parliament and how representative they are of the 28 member states, identifying which policy areas or committees are of particular interest to MEPs from certain countries. It also examines the allocation of committee chairs and party coordinator positions to assess whether the country of origin matters and if so, why. The study reveals that in general the countries’ share of representatives in the committees is very similar in most of the cases to their representation in Parliament. Still, some policy areas have a special relevance for some countries and attract their MEPs in larger numbers. Due to the procedure used in the allocation of the committee chairs, which favours the largest political groups and the largest national parties within them, MEPs from larger member states tend to hold most of these coveted positions. The internal process followed by the political groups in appointing their coordinators in the respective committees is predisposed towards MEPs with seniority, experience and good connections. All in all, the strategic relevance that national parties attach to these positions makes a difference.

Russians or so-called Russian-speakers in Latvia and Estonia pose a significant problem for both countries. Russian-speakers are a numerous minority in Latvia and Estonia, which causes deep division in these countries from the ethnical point of view. The problem of highest importance in the legal aspect is the unregulated status of the Russian-speakers. Though they are permanent residents of Latvia and Estonia many of them still do not have these countries' citizenship. The complex naturalisation procedure introduced by Latvia and Estonia soon after restoring independence in 1991 is considered to be main responsible for this.

The Ross operation remains a controversially discussed procedure when performed in the full root technique because concern exists regarding late dilatation of the pulmonary autograft and regurgitation of the neo-aortic valve. In 2008, we published our short-term experience when using external reinforcement of the autograft, which was inserted into a prosthetic Dacron graft. This detail was thought to prevent neoaortic root dilatation. Since 2006, 22 adult patients have undergone a Ross procedure using this technique. Indications were aortic regurgitation (n = 2), aortic stenosis (n = 15), and combined aortic stenosis and insufficiency (n = 5). A bicuspid aortic valve was present in 10 patients. Prior balloon valvuloplasty had been performed in seven patients. No early or late deaths occurred in this small series. One patient required aortic valve replacement early postoperatively, but freedom from late reoperation is 100% in the 21 remaining patients. Echocardiography confirmed the absence of more than trivial aortic insufficiency in 15 patients after a mean of 70 months (range, 14 to 108 months). No autograft dilatation was observed during follow-up and all patients are in New York Heart Association Class I. Autograft reinforcement is a simple and reproducible technical adjunct that may be especially useful in situations known for late autograft dilatation, namely, bicuspid aortic valve, predominant aortic insufficiency, and ascending aortic enlargement. The mid- to long-term results are encouraging because no late aortic root enlargement has been observed and the autograft valve is well functioning in all cases.
