Exchange Rate Regimes for the New Member States of the European Union
One important issue for the new Member States (NMS) of the EU is the choice of the exchange rate regime that will allow them to participate successfully in the EMU process. Two exchange rate arrangements, compatible with the EU Treaty and ERM2 regulations, deserve special attention: flexible exchange rate regime and currency board with respect to the euro. The first regime (within stipulated bands), coupled with an inflation targeting scheme, agrees with the spirit of the European Commission and absorbs more easily supply shocks and Balassa Samuelson effects (which are present in real convergence and catching up episodes). It also prompts the process of nominal convergence. The second regime is suited to countries that need to foster the credibility of their monetary policy, but makes real adjustments to country-specific shocks and Balassa-Samuelson effects more difficult and/or costly. In this paper we investigate the dynamics of output and inflation under each exchange rate regime in NMS during the post EU accession and Maastricht phases. For that purpose, our model extends Gerlach and Smets (2000) and Detken and Gaspar (2003), icluding market distortions and three possible exchange rate regimes. In the empirical part of the paper we estimate SVAR models, following Bayoumi and Eichengreen (1993) methodology, in order to extract variances and covariances between shocks to each NMS and to the euro zone and compute individual social losses under each exchange rate arrangement. We use monthly data on industrial production and CPI for eight NMS countries. Our main result is that the optimal choice varies depending on the institutional and structural features of each economy, and on the likely source and nature of economic shocks to which it is exposed with respect to the whole euro area. Interestingly, the results for each country seem to conform to the general prescriptions that one would derive from the theory of optimal currency areasEU enlargment, exchange rate systems, SVAR, European monetary integration
A Gravity Approach to Assess the Effects of Association Agreements on Euromediterranean Trade of Fruits and Vegetables
The paper is intended to draw on a gravity methodology to assess the impact of EuroMediterranean Association Agreement on Fruit and Vegetable trade from Mediterranean Partner Countries (MPC) to the EU. The Association Agreements appear to be significant as an explanatory of both fruit and vegetablesâ trade flows to the EU. However, while the impact of such arrangements has contributed to boost MPCâs horticultural exports, it has not been sufficient to compensate the export loss related to the nature of MPCs as third countries. MPCs may have obtained gains from the EuroMed Agrements but the Barcelona process is still far to achieve its initial goals, at least concerning crucial products for the MPCsâ export strategy. The presented approach supplies a method to monitor future developments in the EuroMediterranean process.agricultural trade; Euro-Mediterranean agreements; fruit and vegetables
Probing the Higgs self-coupling through double Higgs production in vector boson scattering at the LHC
In this work we explore the sensitivity to the Higgs self-coupling λ in the production of two Higgs bosons via vector boson scattering at the LHC. Although these production channels, concretely W+WââHH and ZZâHH, have lower rates than gluon-gluon fusion, they benefit from being tree level processes, being independent of top physics and having very distinctive kinematics that allow us to obtain very clean experimental signatures. This makes them competitive channels concerning the sensitivity to the Higgs self-coupling. In order to give predictions for the sensitivity to this coupling, we first study the role of λ at the subprocess level, both in and beyond the Standard Model, to move afterwards to the LHC scenario. We characterize the ppâHHjj case first and then provide quantitative results for the values of λ that can be probed at the LHC in vector boson scattering processes after considering the Higgs boson decays. We focus mainly on ppâbbÂŻbbÂŻjj, since it has the largest signal rates, and also comment on the potential of other channels, such as ppâbb¯γγjj, as they lead to cleaner, although smaller, signals. Our whole study is performed for a center of mass energy of s=14TeV and for various future expected LHC luminositiesThis work is supported by the European Union through the ITN ELUSIVES H2020-MSCA-ITN-2015//674896 and the RISE INVISIBLESPLUS H2020-MSCA-RISE-2015//690575, by the CICYT through the projects FPA2016-78645-P, by the Spanish Consolider-Ingenio 2010 Programme CPAN (CSD2007-00042) and by the Spanish MINECO's âCentro de Excelencia Severo Ochoaâ Programme under grant SEV-2016-0597.

Se ofrece una revisiĂłn de las principales orientaciones teĂłricas sobre redes sociales en el paĂs, asĂ como un esquema en el que se plantean tres tipos de reflexividad: autoconsciente, autorreferente y constitutiva, como vĂas especĂficas para la diferenciaciĂłn del caso de estudio
La ConservaciĂłn del Patrimonio en la Obra Civil al inicio del Siglo XXI y sus riesgos
Una vez que la humanidad ha construido un ingente patrimonio, tanto arquitectĂłnico como en obra civil, uno de los principales problemas que enfrenta la ingenierĂa para el siglo que se inicia es el de su conservaciĂłn! Todas las estructuras tienden a deteriorarse con el tiempo como consecuencia de la adaptaciĂłn de los materiales que las componen al entorno en que se encuentran ubicadas, y de su disposiciĂłn. El mantenimiento en uso de dichas estructuras el mayor tiempo posible genera importantes costes que es preciso reducir con estrategias y tĂ©cnicas racionales. Dentro de todas ellas, este documento, sin embargo, solo se centrarĂĄ en aquellas que, por testimoniar nuestra memoria como colectivo, constituyen elementos de valor histĂłrico. Para examinar los principales problemas de conservaciĂłn que afectan al patrimonio histĂłrico en obra civil, se dividirĂĄn formalmente en sus aspectos criteriolĂłgicos o doctrinales, estratĂ©gicos o metodolĂłgicos, y especĂficamente tĂ©cnicos

MARKET SEGMENTATION AND WILLINGNESS TO PAY FOR ORGANIC PRODUCTS IN SPAIN
In recent years, consumer concerns on environmental and health issues related to food products have increased and, as a result, the demand for organically grown production has grown. Higher costs of production and retailer margins generate a gap between real prices and those that consumers are willing to pay for organic food. In this article, consumer willingness to pay for organic food in two Spanish regions is analyzed. Markets in both regions are segmented considering consumers lifestyles. Results indicate that consumers concerned about healthy diet and environmental degradation are the most likely to buy organic food, and are willing to pay a high premium. Organic attributes are easily identified in perishable products as the premium consumers would pay for organic meat, fruits, and vegetables is higher.Demand and Price Analysis,
Decision-making in an emergency department: A nursing accountability model
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Introduction
Nurses that work in an emergency department regularly care for acute patients in a fast-paced environment, being at risk of suffering high levels of burnout. This situation makes them especially vulnerable to be accountable for decisions they did not have time to consider or have been pressured into.
Research objective
The objective of this study was to find which factors influence ethical, legal and professional accountability in nursing practice in an emergency department.
Research design
Data were analysed, codified and triangulated using qualitative ethnographic content analysis.
Participants and research context
This research is set in a large emergency department in the Midlands area of England. Data was collected from 186 nurses using participant observation, 34 semi-structured interviews with nurses and ethical analysis of 54 applicable clinical policies
Ethical considerations
Ethical approval was granted by two research ethics committees and the National Health Service Health Research Authority.
Results
The main result was the clinical nursing accountability cycle model, which showed accountability as a subjective concept that flows between the nurse and the healthcare institution. Moreover, the relations amongst the clinical nursing accountability factors are also analysed to understand which factors affect decision-making.
Discussion
The retrospective understanding of the factors that regulate nursing accountability is essential to promote that both the nurse and the healthcare institution take responsibility not only for the direct consequences of their actions but also for the indirect consequences derived from previous decisions.
Conclusion
The decision-making process and the accountability linked to it are affected by several factors that represent the holistic nature of both entities, which are organised and interconnected in a complex grid. This pragmatic interpretation of nursing accountability allows the nurse to comprehend how their decisions are affected, while the healthcare institution could act proactively to avoid any problems before they happen
Microrreservas de flora en Castilla y LeĂłn: una herramienta legal para la conservaciĂłn de Senecio coincyi
En junio de 2007 el BoletĂn Oficial de Castilla y LeĂłn publicĂł el Decreto 63/2007 por el cual se estableciĂł el CatĂĄlogo de Flora Protegida de Castilla y LeĂłn y la figura de protecciĂłn denominada Microrreserva de Flora. Ambos, CatĂĄlogo y microrreservas, se han convertido en instrumentos legales complementarios de enorme importancia para la conservaciĂłn de la flora amenazada de esta comunidad autĂłnoma. El objetivo de las microrreservas de flora es declarar como espacios protegidos ĂĄreas de reducida extensiĂłn -menos de 200 hectĂĄreas- que presenten el mĂĄximo interĂ©s por albergar poblaciones sobresalientes de las especies mĂĄs amenazadas incluidas en el CatĂĄlogo de Flora Protegida de Castilla y LeĂłn. Para desarrollar esta ley (Decreto 63/2007), la ConsejerĂa de Medio Ambiente de la Junta de Castilla y LeĂłn estableciĂł en el año 2008 un convenio especĂfico con la Universidad de LeĂłn con el fin de realizar los necesarios trabajos cientĂficos y tĂ©cnicos que permitan identificar ĂĄreas susceptibles de ser declaradas microrreservas de flora
A comparative analysis between two statistical deviationâbased consensus measures in group decision making problems
The mean absolute deviation and the standard deviation, two statistical measures commonly used in quantifying variability, may become an interesting tool when defining consensus measures. Two consensus indexes which obtain the level of consensus in some problems of Group Decision Making are introduced in this paper by expanding the aforementioned statistical concepts. A comparative analysis reveals that the levels of consensus derived from these indexes are close to those obtained employing distance functions when a fuzzy preference relations frame is considered, so they turn out to be a useful tool in this context. In addition, these indexes are different from each other and with the distance functions considered. Thus, they are applicable tools in the calculation of consensus in our context and are different from those commonly used
