The EU Banking Union combines micro- and macro-prudential regulation. It aims at breaking the “doom loop” between banks and sovereign debt, promoting financial stability and mitigating the next financial shock to the real EU economy, at the lowest possible cost to the financial institutions and to the taxpayers. Success, or failure, is determined by how the banking union copes with the challenges to its two main pillars, the Single Supervisory Mechanism (SSM) and the Single Resolution Mechanism (SRM). Under the SSM, in its new supervisory role, the ECB may be subject to conflicts between the objectives of price and financial stability, and the single-supervisor role may be sub-optimal. Two regulators might have been preferable and more focus on ECB accountability will now be required. The shock-absorbing Single Resolution Fund (SRF), which is part of the SRM, may not have the capacity to deal with a crisis of the size of the one of 2008. Especially as the nature and severity of a future financial crisis cannot be forecasted. The design of the banking union is not the result of theoretical studies, but a political compromise to deal with an acute crisis. The theoretical studies that are included in this paper are not supportive of the banking union in its current form. Nevertheless, there is a good chance that the EU Banking Union may succeed, as ECB supervision of the 123 systemically important banks should contain potential demands on the SRM. In the event of a crisis that is too severe for the banking union to absorb with its current capability, the crucial assumption is that there is political will to rapidly provide new resources. The same applies, if a major financial crisis develops before the banking union is fully operational.

The strategic orientation of firms can take on many forms. Researchers most commonly distinguish between entrepreneurial, market, and learning orientations. In combination, strategic orientations represent a firm's value proposition in terms of the markets in which it operates, where it deploys its resources, and which behavioral patterns are established. This thesis provides insights into the effectiveness of strategic orientations by adopting multiple theoretical perspectives. The strategic orientations of entrepreneurial, market, learning, and innovation orientations are investigated in an isolated as well as interrelated manner. The first research article concentrates on entrepreneurial orientation as its conceptualization and operationalization is subject to several debates in the literature. This conceptual study shows how the challenges of the entrepreneurial orientation construct can be overcome in future research to arrive at a higher level of construct clarity. Thereby, the theoretical perspectives of entrepreneurial dominant logic and the theory of planned behavior are employed. The literature has predominantly focused on investigating the effectiveness of particular strategic orientations. Recently, scholars have stressed their synergetic impact on firm performance and, as such, the relevance of considering their combined role in creating superior value for firms. However, empirical research on their interrelatedness remains scant and dispersed, making it necessary to conduct further research on strategic orientations in an integrative manner. As such, the second research article demonstrates which interrelated roles are played by entrepreneurial, market, and learning orientations in their relationship to firm performance. The rich body of existing knowledge is synthesized by means of meta-analysis under the perspective of strategic coalignment as well as the resource-based view of the firm.

This paper takes a critical and evaluative stance toward micro-activity-based approaches to understanding strategy. It argues that such approaches bring with them important theoretical and empirical challenges. The paper argues against a tendency to reductionism without equal emphasis to the contextual influences that bound micro-strategising. Finally, the paper argues for a more international and comparative approach to micro-strategy studies than has currently been the case.

In 2002, we published a paper [Brock, J., Brown, C., Boucher, J., Rippon, G., 2002. The temporal binding deficit hypothesis of autism. Development and Psychopathology 142, 209-224] highlighting the parallels between the psychological model of 'central coherence' in information processing [Frith, U., 1989. Autism: Explaining the Enigma. Blackwell, Oxford] and the neuroscience model of neural integration or 'temporal binding'. We proposed that autism is associated with abnormalities of information integration that is caused by a reduction in the connectivity between specialised local neural networks in the brain and possible overconnectivity within the isolated individual neural assemblies. The current paper updates this model, providing a summary of theoretical and empirical advances in research implicating disordered connectivity in autism. This is in the context of changes in the approach to the core psychological deficits in autism, of greater emphasis on 'interactive specialisation' and the resultant stress on early and/or low-level deficits and their cascading effects on the developing brain [Johnson, M.H., Halit, H., Grice, S.J., Karmiloff-Smith, A., 2002. Neuroimaging of typical and atypical development: a perspective from multiple levels of analysis. Development and Psychopathology 14, 521-536].We also highlight recent developments in the measurement and modelling of connectivity, particularly in the emerging ability to track the temporal dynamics of the brain using electroencephalography (EEG) and magnetoencephalography (MEG) and to investigate the signal characteristics of this activity. This advance could be particularly pertinent in testing an emerging model of effective connectivity based on the balance between excitatory and inhibitory cortical activity [Rubenstein, J.L., Merzenich M.M., 2003. Model of autism: increased ratio of excitation/inhibition in key neural systems. Genes, Brain and Behavior 2, 255-267; Brown, C., Gruber, T., Rippon, G., Brock, J., Boucher, J., 2005. Gamma abnormalities during perception of illusory figures in autism. Cortex 41, 364-376]. Finally, we note that the consequence of this convergence of research developments not only enables a greater understanding of autism but also has implications for prevention and remediation. © 2006.

Warehouse is an essential component in the supply chain, linking the chain partners and providing them with functions of product storage, inbound and outbound operations along with value-added processes. Allocation of warehouse resources should be efficient and effective to achieve optimum productivity and reduce operational costs. Radio frequency identification (RFID) is a technology capable of providing real-time information about supply chain operations. It has been used by warehousing and logistic enterprises to achieve reduced shrinkage, improved material handling and tracking as well as increased accuracy of data collection. However, both academics and practitioners express concerns about challenges to RFID adoption in the supply chain. This paper provides a comprehensive analysis of the problems encountered in RFID implementation at warehouses, discussing the theoretical and practical adoption barriers and causes of not achieving full potential of the technology. Lack of foreseeable return on investment (ROI) and high costs are the most commonly reported obstacles. Variety of standards and radio wave frequencies are identified as source of concern for decision makers. Inaccurate performance of the RFID within the warehouse environment is examined. Description of integration challenges between warehouse management system and RFID technology is given. The paper discusses the existing solutions to technological, investment and performance RFID adoption barriers. Factors to consider when implementing the RFID technology are given to help alleviate implementation problems. By illustrating the challenges of RFID in the warehouse environment and discussing possible solutions the paper aims to help both academics and practitioners to focus on key areas constituting an obstacle to the technology growth. As more studies will address these challenges, the realisation of RFID benefits for warehouses and supply chain will become a reality.

Background Changing the relationship between citizens and the state is at the heart of current policy reforms. Across England and the developed world, from Oslo to Ontario, Newcastle to Newquay, giving the public a more direct say in shaping the organization and delivery of healthcare services is central to the current health reform agenda. Realigning public services around those they serve, based on evidence from service user's experiences, and designed with and by the people rather than simply on their behalf, is challenging the dominance of managerialism, marketization and bureaucratic expertise. Despite this attention there is limited conceptual and theoretical work to underpin policy and practice. Objective This article proposes a conceptual framework for patient and public involvement (PPI) and goes on to explore the different justifications for involvement and the implications of a rights-based rather than a regulatory approach. These issues are highlighted through exploring the particular evolution of English health policy in relation to PPI on the one hand and patient choice on the other before turning to similar patterns apparent in the United States and more broadly. Conclusions A framework for conceptualizing PPI is presented that differentiates between the different types and aims of involvement and their potential impact. Approaches to involvement are different in those countries that adopt a rights-based rather than a regulatory approach. I conclude with a discussion of the tension and interaction apparent in the globalization of both involvement and patient choice in both policy and practice. © 2009 Blackwell Publishing Ltd.

The publication represents a multi-dimensional and multi-faced, in depth assessment of the most significant determinants of the EU development as a political, economic and legal entity, in its format emerging from the Lisbon Treaty. The book represents an important contribution to our understanding of the most profound issues in the recent process of EU integration, including the issue of maintaining its cohesion and coherence under the stress of global challanges faced also by the European Union. Autohors formulated worthwhile conclusions of high value not only for academics but also for political decision-makers, which gives the book same competitive edge over its more theoretical and, hence, less practice-oriented, knack. The arumentation presented in the book would not be left without a reaction of the academic and/or professional circles. I take it almost for granted that the overall setting of the argumentation presented in it, as well as specific points made in its various chapters would find their adequate resonance in a high profile discussion likely to emerge after the book would have been published.

Outsourcing or offshoring as it is now known has been around for many decades. In the beginning, it was only very peripheral activities that were outsourced, i.e. blue-collar (lower skilled) work but this is now all changing with the outsourcing of white-collar jobs. The digital revolution, the falling costs of transport and telecom costs and the opening up of the global economy helped the outsourcing market. For companies going down or contemplating the road of outsourcing there are both potential benefits and challenges, for example, the type of outsourcing they want to get involved in, and the country they want to outsource to. Outsourcing can potentially happen anywhere in the world where the costs are lower and the quality higher. The main places that have been used for outsourcing have been India, China, Ireland, South-East Asia, Russia, Mexico and the Czech Republic. The research currently underway is initially focusing on a literature review of current outsourcing applications in the market place. From this literature review, a questionnaire is being developed to assess the impact Outsourcing has on businesses. This research focuses on the Irish Market place.

Multiscale systems that are characterized by a great range of spatial–temporal scales arise widely in many scientific domains. These range from the study of protein conformational dynamics to multiphase processes in, for example, granular media or haemodynamics, and from nuclear reactor physics to astrophysics. Despite the diversity in subject areas and terminology, there are many common challenges in multiscale modelling, including validation and design of tools for programming and executing multiscale simulations. This Theme Issue seeks to establish common frameworks for theoretical modelling, computing and validation, and to help practical applications to benefit from the modelling results. This Theme Issue has been inspired by discussions held during two recent workshops in 2013: ‘Multiscale modelling and simulation’ at the Lorentz Center, Leiden (http://www.lorentzcenter.nl/lc/web/2013/569/info.php3?wsid=569&venue=Snellius), and ‘Multiscale systems: linking quantum chemistry, molecular dynamics and microfluidic hydrodynamics’ at the Royal Society Kavli Centre. The objective of both meetings was to identify common approaches for dealing with multiscale problems across different applications in fluid and soft matter systems. This was achieved by bringing together experts from several diverse communities.

Existing political theory, particularly which deals with justice and/or rights, has long assumed citizenship as a core concept. Noncitizenship, if it is considered at all, is generally defined merely as the negation or deprivation of citizenship. As such, it is difficult to examine successfully the status of noncitizens, obligations towards them, and the nature of their role in political systems. This article addresses this critical gap by defining the theoretical problem that noncitizenship presents and demonstrating why it is an urgent concern. It surveys the contributions to the special issue for which the article is an introduction, drawing on cross-cutting themes and debates to highlight the importance of theorising noncitizenship due to both the problematic gap that exists in the theoretical literature, and the real world problems created as a result of noncitizenship which are not currently successfully addressed. Finally, the article discusses key future directions for the theorisation of noncitizenship.

The latest reform of the Common Agricultural Policy (CAP) has recently been accepted, identifying important challenges for EU agriculture, but proposing only limited changes to the previous CAP. Now it is time for the implementation of the new measures. However, from a theoretical point of view, it seems that the CAP can hardly meet the challenges it faces due to the inconsistencies between the predefined challenges and the measures proposed to meet them. The aim of the paper is to systematically analyse the consistency between the challenges of European agriculture and the policy measures aimed at meeting them. It seems that not all measures are consistent with the challenges.

This study evaluated the relative fit of both Finn's (1989) Participation-Identification and Wehlage, Rutter, Smith, Lesko and Fernandez's (1989) School Membership models of high school completion to a sample of 4,597 eighth graders taken from the National Educational Longitudinal Study of 1988, (NELS:88), utilizing structural equation modeling techniques. This study found support for the importance of educational engagement as a factor in understanding academic achievement. The Participation-Identification model was particularly well fitting when applied to the sample of high school completers, dropouts (both overall and White dropouts) and African-American students. This study also confirmed the contribution of school environmental factors (i.e., size, diversity of economic and ethnic status among students) and family resources (i.e., availability of learning resources in the home and parent educational level) to students' educational engagement. Based on these findings, school social workers will need to be more attentive to utilizing macro-level interventions (i.e., community organization, interagency coordination) to achieve the organizational restructuring needed to address future challenges. The support found for the Participation-Identification model supports a shift in school social workers' attention from reactive attempts to improve the affective-interpersonal lives of students to proactive attention to their academic lives. The model concentrates school social work practices on the central mission of schools, which is educational engagement. School social workers guided by this model would be encouraged to seek changes in school policies and organization that would facilitate educational engagement. ^

‘Noncitizenship’, if it is considered at all, is generally seen only as the negation or deprivation of citizenship. It is rarely examined in its own right, whether in relation to States, to noncitizens, or citizens. This means that it is difficult to examine successfully the status of noncitizens, obligations towards them, and the nature of their role in political systems. As a result, not only are there theoretical black holes, but also the real world difficulties created as a result of noncitizenship are not currently successfully addressed. In response, Theorising Noncitizenship seeks to define the theoretical challenge that noncitizenship presents and to consider why it should be seen as a foundational concept in social science. The contributions, from leading scholars in the field and across disciplinary backgrounds, capture a diversity of perspectives on the meaning, position and lived experience of noncitizenship. They demonstrate that, we need to look beyond citizenship in order to take noncitizenship seriously and to capture fully the lived realities of the contemporary State system. This book was previously published as a special issue of Citizenship Studies.
