The financial and economic crisis has hit Europe in its core. While the crisis may not have originated in the European Union, it has laid bare structural weaknesses in the EU’s policy framework. Both public finances and the banking sector have been heavily affected. For a long time, the EU failed to take into account sufficiently the perverse link that existed between the two. Negative evolutions in one field of the crisis often dragged along the other in its downward spiral. In June 2012, in the early hours of a yet another EU Summit, the leaders of the eurozone finally decided to address the link between the banking and sovereign debt crises. Faced with soaring public borrowing costs in Spain and Italy, they decided to allow for the direct European recapitalisation of banks when the Member State itself would no longer be in a position to do so. In exchange, supervision of the banking sector would be lifted to the European level by means of a Single Supervisory Mechanism. The Single Supervisory Mechanism, or SSM in the EU jargon, is a first step in the broader revision of policies towards banks in Europe. The eventual goal is the creation of a Banking Union, which is to carry out effective surveillance and – if needed – crisis management of the banking sector. The SSM is to rely on national supervisors and the ECB, with the ECB having final authority on the matter. The involvement of the latter made it clear that the SSM would be centred on the eurozone – while it is to remain open to other Member States willing to join. Due to the ongoing problems and the link between the creation of the SSM and the recapitalisation of banks, the SSM became one of the key legislative priorities of the EU. In December 2012, Member States reached an agreement on the design of the SSM. After discussions with the European Parliament (which were still ongoing at the time of writing), the process towards making the SSM operational can be initiated. The goal is to have the SSM fully up and running in the first half of 2014. The decisions that were taken in June 2012 are likely to have had a bigger impact than the eurozone’s Heads of State and Government could have realised at the time for two important reasons. On the one hand, creating the SSM necessitates a full Banking Union and therefore shared risk. On the other hand, the decisions improved the ECB’s perception of the willingness of governments to take far-reaching measures. This undoubtedly played a significant role in the creation of the Outright Monetary Transactions programme by the ECB, which has led to a substantial easing of the crisis in the short-term. 1 These short-term gains should now be matched with a stable long-term framework for bank supervision and crisis management. The agreement on the SSM should be the first step in the direction of this goal. This paper provides an analysis of the SSM and its role in the creation of a Banking Union. The paper starts with a reminder of why the EU decided to put in place the SSM (§1) and the state of play of the ongoing negotiations on the SSM (§2). Subsequently, the supervisory responsibilities of the SSM are detailed, including its scope and the division of labour between the national supervisors and the ECB (§3). The internal functioning of the SSM (§4) and its relation to the other supervisors are discussed afterwards (§5). As mentioned earlier, the SSM is part of a wider move towards a Banking Union. Therefore, this paper sheds light on the other building blocks of this ambitious project (§6). The transition towards the Banking Union is important and will prove to be a bumpy ride. Before formulating a number of conclusions, this Working Paper therefore provides an overview of the planned road ahead (§7).

Enforcement of and compliance with laws and regulations in the single market of the European Union are not only legally necessary, but also of crucial economic importance for business, consumers and the EU economy at large. This book provides a comprehensive overview of the current EU enforcement landscape and its functioning. The classical infringement route via the Court of Justice of the European Union remains critical as a last resort, but it is increasingly seen as very slow and costly. The new emphasis relies heavily on a range of pre-infringement as well as preventive initiatives that prevent new technical barriers from arising. They also tend to be far less costly and more rapid, informal and effective in pursuing a properly functioning internal market. These improvements are welcome news for the single market, yet EU enforcement still has problems to solve, for example in the area of public procurement.

This study explores the existing policy problems and the possible options for reforming the EU copyright framework as provided by EU Directive 29/2001 on Copyright in the Information Society (InfoSoc Directive) and related legislation, with a specific focus on the need to strengthen the Internal Market for creative content. We find two main policy problems: i) the absence of a Digital Single Market for creative works; and ii) the increasing tension between the current system of exceptions and limitations and the legal treatment of emerging uses of copyrighted content in the online environment. Without prejudicing a future impact assessment that might focus on more specific and detailed policy options, our analysis suggests that ‘more Europe’ would be needed in the field of copyright, given the existing sources of productive, allocative and dynamic efficiency associated with the current system. Looking at copyright from an Internal Market perspective would, in this respect, also help to address many of the shortcomings in the current framework, which undermine legal certainty and industrial policy goals.

Highlights • In its Digital Single Market strategy, the European Commission has rightly noted the importance of reducing the price paid for basic cross-border parcel delivery by consumers and by small and medium size retail senders. • The payment flows for cross-border parcel delivery are strikingly similar to those for telecommunications. Comparisons with roaming can be instructive. As with roaming, it is clear that the links between wholesale payments between the national postal operators and retail prices need to be properly understood in order to craft good policy. Another useful lesson is that national postal regulatory authorities are unlikely to address cross-border problems because of limitations in their respective mandates and because they have no incentive to take measures to benefit residents of other countries. • There are also significant differences between roaming and parcel delivery.While high wholesale charges were a major driver of high retail prices for international mobile roaming, the wholesale payments for cross-border parcel delivery appear to be below cost.This implies that it is the ‘spread’ between retail price and thewholesale payment that is inflated, at least for small retail senders and for consumers. • Comprehensive statistics gathering, coordinated at European level, is indispensable.

The aim of this study was to analyze the psychometric properties of the Spanish translation of the List of Social Situation Problems (LSSP; S. H. Spence, 1980). The questionnaire was administered to a sample of 388 adolescents between the ages of 12 and 18. Exploratory factor analysis identified four factors: Social Anxiety, Adult Oppositional, Assertiveness, and Making Friends, which accounted for 26.64% of the variance. Internal consistency of the total scale was high (alpha = .86). Correlations between the LSSP and two self-report measures of social anxiety, the Questionnaire about Interpersonal Difficulties for Adolescents (r = .45) and the Social Phobia and Anxiety Inventory (r = .48), were statistically significant. A significant difference was found between LSSP total scores for adolescents with and without social anxiety (d = 1.14), supporting the construct validity of the scale.

Research in conditioning (all the processes of preparation for competition) has used group research designs, where multiple athletes are observed at one or more points in time. However, empirical reports of large inter-individual differences in response to conditioning regimens suggest that applied conditioning research would greatly benefit from single-subject research designs. Single-subject research designs allow us to find out the extent to which a specific conditioning regimen works for a specific athlete, as opposed to the average athlete, who is the focal point of group research designs. The aim of the following review is to outline the strategies and procedures of single-subject research as they pertain to.. the assessment of conditioning for individual athletes. The four main experimental designs in single-subject research are: the AB design, reversal (withdrawal) designs and their extensions, multiple baseline designs and alternating treatment designs. Visual and statistical analyses commonly used to analyse single-subject data, and advantages and limitations are discussed. Modelling of multivariate single-subject data using techniques such as dynamic factor analysis and structural equation modelling may identify individualised models of conditioning leading to better prediction of performance. Despite problems associated with data analyses in single-subject research (e.g. serial dependency), sports scientists should use single-subject research designs in applied conditioning research to understand how well an intervention (e.g. a training method) works and to predict performance for a particular athlete.

Objective: The Temptation and Restraint Inventory (TRI) is commonly used to measure drinking restraint in relation to problem drinking behavior. However, as yet the TRI has not been validated in a clinical group with alcohol dependence. Method: Male (n = 111) and female (n = 57) inpatients with DSM-IV diagnosed alcohol dependence completed the TRI and measures of problem drinking severity, including the Alcohol Dependence Scale and the quantity, frequency and week total of alcohol consumed. Results: The factor structure of the TRI was replicated in the alcohol dependent sample. Cognitive Emotional Preoccupation (CEP), one of the two higher order factors of the TRI, demonstrated sound predictive power toward all dependence severity indices. The other higher order factor, Cognitive Behavioral Control (CBC), was related to frequency of drinking. There was limited support for the CEP/CBC interactional model of drinking restraint. Conclusions: Although the construct validity of the TRI was sound, the measure appears more useful in understanding the development, maintenance and severity of alcohol-related problems in nondependent drinkers. The TRI may show promise in detecting either continuous drinking or heavy episodic type dependent drinkers.

We have proposed a novel robust inversion-based neurocontroller that searches for the optimal control law by sampling from the estimated Gaussian distribution of the inverse plant model. However, for problems involving the prediction of continuous variables, a Gaussian model approximation provides only a very limited description of the properties of the inverse model. This is usually the case for problems in which the mapping to be learned is multi-valued or involves hysteritic transfer characteristics. This often arises in the solution of inverse plant models. In order to obtain a complete description of the inverse model, a more general multicomponent distributions must be modeled. In this paper we test whether our proposed sampling approach can be used when considering an arbitrary conditional probability distributions. These arbitrary distributions will be modeled by a mixture density network. Importance sampling provides a structured and principled approach to constrain the complexity of the search space for the ideal control law. The effectiveness of the importance sampling from an arbitrary conditional probability distribution will be demonstrated using a simple single input single output static nonlinear system with hysteretic characteristics in the inverse plant model.

The thesis is concerned with the electron properties of single-polepiece magnetic electron lenses especially under conditions of extreme polepiece saturation. The electron optical properties are first analysed under conditions of high polepiece permeability. From this analysis, a general idea can be obtained of the important parameters that affect ultimate lens performance. In addition, useful information is obtained concerning the design of improved lenses operating under conditions of extreme polepiece saturation, for example at flux densities of the order of 10 Tesla. It is shown that in a single-polepiece lens , the position and shape of the lens exciting coil plays an important role. In particular, the maximum permissible current density in the windings,rather than the properties of the iron, can set a limit to lens performance. This factor was therefore investigated in some detail. The axial field distribution of a single-polepiece lens, unlike that of a conventional lens, is highly asymmetrical. There are therefore two possible physical arrangements of the lens with respect to the incoming electron beam. In general these two orientations will result in different aberration coefficients. This feature has also been investigated in some detail. Single-pole piece lenses are thus considerably more complicated electron- optically than conventional double polepiece lenses. In particular, the absence of the usual second polepiece causes most of the axial magnetic flux density distribution to lie outside the body of the lens. This can have many advantages in electron microscopy but it creates problems in calculating the magnetic field distribution. In particular, presently available computer programs are liable to be considerably in error when applied to such structures. It was therefore necessary to find independent ways of checking the field calculations. Furthermore, if the polepiece is allowed to saturate, much more calculation is involved since the field distribution becomes a non-linear function of the lens excitation. In searching for optimum lens designs, care was therefore taken to ensure that the coil was placed in the optimum position. If this condition is satisfied there seems to be no theoretical limit to the maximum flux density that can be attained at the polepiece tip. However , under iron saturation condition, some broadening of the axial field distribution will take place, thereby changing the lens aberrations . Extensive calculations were therefore made to find the minimum spherical and chromatic aberration coefficients . The focal properties of such lens designs are presented and compared with the best conventional double-polepiece lenses presently available.

This research examines women GPs' careers, how they run their practices and how they reconcile professional and domestic lives. It looks at the particular experiences of women GPs who practise alone, and at the pressures in past practice experience which have led them to do so. It is argued that many of the problems of group practice which can be identified are attributable to gender. For example, one reason given for entering general practice is a desire to be able to provide the full range of medical care and not to specialise. Women GPs, however, may find themselves seeing more women patients for "women's problems" and children than they would freely choose. Women have not entered general practice in order to specialise in these areas of medicine. Indeed, if they had wanted to specialise in obstetrics, gynaecology or paediatrics they would have had difficulty advancing very far in these male-dominated areas of hospital hierarchy. Other gender related problems exist for women in general practice and practising single-handedly is one strategy that women GPs have used to counter the problems of working in male-dominated practices and partnerships. However, the twenty-four hour commitment of single-handed practice may bring further pressures in reconciling this with responsibility for home life. Out-of-hours cover, which can be viewed as the link between professional and domestic life, where the one intrudes into the other, is also examined in terms of the gender issues it raises. The interaction of gender and ethnicity is also considered for the 11 Asian women GPs in the study. Interviews were conducted with 29 single-handed women GPs in the Midlands. In addition, some cases were studied in greater depth by being observed in their surgeries and on home visits for a day each. A qualitative/feminist approach to analysis has been employed.

The use of the multiple indicators, multiple causes model to operationalize formative variables (the formative MIMIC model) is advocated in the methodological literature. Yet, contrary to popular belief, the formative MIMIC model does not provide a valid method of integrating formative variables into empirical studies and we recommend discarding it from formative models. Our arguments rest on the following observations. First, much formative variable literature appears to conceptualize a causal structure between the formative variable and its indicators which can be tested or estimated. We demonstrate that this assumption is illogical, that a formative variable is simply a researcher-defined composite of sub-dimensions, and that such tests and estimates are unnecessary. Second, despite this, researchers often use the formative MIMIC model as a means to include formative variables in their models and to estimate the magnitude of linkages between formative variables and their indicators. However, the formative MIMIC model cannot provide this information since it is simply a model in which a common factor is predicted by some exogenous variables—the model does not integrate within it a formative variable. Empirical results from such studies need reassessing, since their interpretation may lead to inaccurate theoretical insights and the development of untested recommendations to managers. Finally, the use of the formative MIMIC model can foster fuzzy conceptualizations of variables, particularly since it can erroneously encourage the view that a single focal variable is measured with formative and reflective indicators. We explain these interlinked arguments in more detail and provide a set of recommendations for researchers to consider when dealing with formative variables.
