The first in a series for a CEPS-EPIN project entitled “The British Question and the Search for a Fresh European Narrative” this paper is pegged on an ambitious ongoing exercise by the British government to review all the competences of the European Union. The intention is that this should provide a basis for informed debate before the referendum on the UK remaining in the EU or not, which is scheduled for 2017. This paper summarises the first six reviews, each of which runs to around 80 pages, covering foreign policy, development policy, taxation, the single market, food safety, and public health. The present authors then add their own assessments of these materials. While understandably giving due place to British interests, they are of general European relevance. The substantive conclusions of this first set of reviews are that the competences of the EU are judged by respondents to be ‘about right’ on the whole, which came as a surprise to eurosceptic MPs and the tabloid media. Our own view is that the reviews are objective and impressively researched, and these populist complaints are illustrating the huge gap between the views of informed stakeholders and general public opinion, and therefore also the hazard of subjecting the ‘in or out’ choice for decision by referendum. If the referendum is to endorse the UK’s continuing membership there will have to emerge some fresh popular narratives about the EU. The paper therefore concludes with some thoughts along these lines, both for the UK and the EU as a whole.

This paper is the second in a series for a CEPS project entitled “The British Question and the Search for a Fresh European Narrative”. It is pegged on an ambitious exercise by the British government to review all the competences of the European Union on the basis of evidence submitted by independent stakeholders. In all, 32 sectoral policy reviews are being produced over the period 2013-2015, as input into public information and debate leading up to a referendum on whether the UK should remain in, or secede from, the EU, planned for 2017. This second set of reviews covers a broad range of EU policies (for the single market for goods, external trade, transport policy, environment, climate change, research, asylum, non-EU immigration, civil judicial cooperation, tourism, culture and sport). The findings confirm what emerged from the first set of reviews, namely that there is little or no case for repatriation of EU competences at the level they are defined in the treaties. This does not exclude that at a more detailed level there can be individual actions or laws that might be done better or not at all. However, that is the task of all the institutions to work at on a regular basis, and hardly a rationale for secession. For the UK in particular the EU has shown considerable flexibility in agreeing to special arrangements, such as in the case of the policies here reviewed of asylum, non-EU immigration and civil judicial cooperation. In other areas reviewed here, such as the single market for goods, external trade, transport, environment, climate change and research, there is a good fit between the EU’s policies and UK priorities, with the EU perceived by stakeholders as an ‘amplifier’ of British interests.

This paper, the third in a series for a CEPS project on the ‘The British Question’, is pegged on an ambitious exercise by the British government to review all the competences of the European Union on the basis of evidence submitted by independent stakeholders. The reviews considered in this paper cover the following EU policies: the single market for services, financial markets, the free movement of people, cohesion, energy, agriculture, fisheries, competition, social and employment policies, and fundamental rights. The declared objective of Prime Minister Cameron is to secure a ‘new settlement’ between the UK and the EU. From political speeches in the UK one can identify three different types of possible demand: reform of EU policies, renegotiation of the UK’s specific terms of membership, and repatriation of competences from the EU back to the member states. As most of the reviews are now complete, three points are becoming increasingly clear: i) The reform agenda – past, present or future - concerns virtually every branch of EU policy, including several cases reviewed here that are central to stated UK economic interests. The argument that the EU is ‘unreformable’ is shown to be a myth. ii) The highly sensitive cases of immigration from the EU and social policies may translate into requests for renegotiation of specific conditions for the UK, but further large-scale opt-outs, as in the case of the euro and justice and home affairs, are implausible. iii) While demands for repatriation of EU competences are voiced in general terms in public debate in the UK, no specific proposals emerge from the evidence as regards competences at the level at which they are identified in the treaties, and there is no chance of achieving consensus for such ideas among member states.

The aim of this paper is to analyse the proposed Directive on criminal sanctions for insider dealing and market manipulation (COM(2011)654 final), which represents the first exercise of the European Union competence provided for by Article 83(2) of the Treaty on the Functioning of the European Union. The proposal aims at harmonising the sanctioning regimes provided by the Member States for market abuse, imposing the introduction of criminal sanctions and providing an opportunity to critically reflect on the position taken by the Commission towards the use of criminal law. The paper will discuss briefly the evolution of the EU’s criminal law competence, focusing on the Lisbon Treaty. It will analyse the ‘essentiality standard’ for the harmonisation of criminal law included in Article 83(2) TFEU, concluding that this standard encompasses both the subsidiarity and the ultima ratio principles and implies important practical consequences for the Union’s legislator. The research will then focus on the proposed Directive, trying to assess if the Union’s legislator, notwithstanding the ‘symbolic’ function of this proposal in the financial crisis, provides consistent arguments on the respect of the ‘essentiality standard’. The paper will note that the proposal raises some concerns, because of the lack of a clear reliance on empirical data regarding the essential need for the introduction of criminal law provisions. It will be stressed that only the assessment of the essential need of an EU action, according to the standard set in Article 83(2) TFEU, can guarantee a coherent choice of the areas interested by the harmonisation process, preventing the legislator to choose on the basis of other grounds.

Intercultural competence (IC) as an essential part of conceptualization of the cultural dimension in FLT has been promoted by educationalists as the most preferred type of competence. One of the challenges of incorporating IC into FLT is to move from the recognition of IC as a model of teaching (Byram, Nichols and Stevens, 2001) to the development of practical applications. This can be due to the fact that teachers do not have sufficient knowledge of the theory behind the concept and consequently, have difficulties to implement the curriculum requirements with regards to IC into their teaching. The purpose of this study was to investigate how teachers of English in upper secondary schools in Sweden interpret the concept of IC and, accordingly, what is their view of culture in English language teaching. In order to answer the research question, I used an exploratory investigation by adopting a qualitative research method in form of semi-structured interviews. The results are similar to the previous studies (Lundgren, 2002; Larzén, 2005) and suggest that teachers lack theoretical background and central guidance with regards to IC and do not always integrate language and culture into an intercultural model of the English language pedagogy.

To examine the question of whether Queensland judicial officers endorse the need for competence tests for non-accused child witnesses in criminal proceedings, a mail survey was sent to judicial officers - questions considered the need to distinguish between children's sworn and unsworn evidence - relevance of age to competence - desirability of competence test formalities.

The non-geniculate crustose coralline alga (CCA) Mastophora pacifica can induce the metamorphosis of competent Haliotis asinina (Vetigastropoda) larvae. The ability to respond to this natural cue varies considerably with larval age, with a higher proportion of older larvae (e.g. 90 h) able to metamorphose in response to M. pacifica than younger larvae (e.g. 66 h). Here we document the variation in time to acquisition of competence within a larval age class. For example, after 18 h of exposure to M. pacifica, approximately 15 and 36% of 84 and 90-h-old H. asinina larvae had initiated metamorphosis, respectively. This age-dependent response to M. pacifica is also observed when different aged larvae are exposed to CCA for varying periods. A higher proportion of older larvae require shorter periods of exposure to CCA than younger larvae in order to initiate metamorphosis. In this experiment, as in the previous, a small proportion of young larvae were able to respond to brief periods of CCA exposure, suggesting that they had developed the same state of competency as the majority of their older counterparts. Comparisons of the proportions of larvae undergoing metamorphosis between families reveals that parentage also has a significant (P < 0.05) affect on whether an individual will initiate metamorphosis at a given age. These familial differences are more pronounced when younger, largely pre-competent larvae (i.e. 66 h old) are exposed to M. pacifica, with proportions of larvae undergoing metamorphosis differing by as much as 10 fold between families. As these data suggest that variation in the rate of development of the competent state has a genetic basis, and as a first step towards identifying the molecular basis to this variation, we have identified numerous genes that are differentially expressed later in larval development using a differential display approach. Spatial expression analysis of these genes suggests that they may be directly involved in the acquisition of competence, or may play a functional role in the postlarva following metamorphosis.
