The implications for the EU and national budgets of the use of EU instruments for macro-financial stability. CEPS Special Report, 4 September 2012

The euro crisis has forced member states and the EU institutions to create a series of new instruments to safeguard macro-financial stability of the Union. This study describes the status of existing instruments, the role of the European Parliament and how the use of the instruments impinges on the EU budget also through their effects on national budgets. In addition, it presents a survey of other possible instruments that have been proposed in recent years (e.g. E-bonds and eurobonds), in order to provide an assessment of how EU macro-financial stability assistance could evolve in the future and what could be its impact on EU public finances.

Do the citizens of the EU actually know what it is worth to them personally? The surveys increasingly suggest that they reject it and regard it with contempt. After living for years in a state of emergency, many people have started to cast doubt on the whole notion of integration, and on the ability of the politicians involved to find meaningful solutions to the crisis.

Evaluation of the use of radiosonde humidity data to predict the occurrence of persistent contrails

Regular visual observations of persistent contrails over Reading, UK, have been used to evaluate radiosonde measurements of temperature and humidity defining cold ice-supersaturated atmospheric regions which are assumed to be a necessary condition for persistent condensation trails (contrails) to form. Results show a good correlation between observations and predictions using data from Larkhill, 63 km from Reading. A statistical analysis of this result and the forecasts using data from four additional UK radiosonde stations are presented. The horizontal extent of supersaturated layers could be inferred from this to be several hundred kilometres. The necessity of bias corrections to radiosonde humidity measurements is discussed and an analysis of measured ice-supersaturated atmospheric layers in the troposphere is presented. It is found that ice supersaturation is more likely to occur in winter than in summer, with frequencies of 17.3% and 9.4%, respectively, which is mostly due to the layers being thicker in winter than in summer. The most probable height for them to occur is about 10 km.

Plant remains as evidence for seasonality of site use in the Mesolithic period

Attempts to identify the seasons during which Mesolithic sites may have been occupied have usually concentrated on evidence from faunal assemblages, while the potential of plant remains has been largely neglected. In this paper the use of plant remains as indicators of seasonality is discussed, especially where they represent the accidental charring of species unlikely to have been deliberately collected and stored. This is illustrated with reference to the early Mesolithic site of Star Carr, North Yorkshire, and discussed in the context of other Mesolithic sites from which assemblages of charred plant remains have been recovered.

Case study of the use of remotely sensed data for modeling flood inundation on the river Severn, UK.

A methodology for using remotely sensed data to both generate and evaluate a hydraulic model of floodplain inundation is presented for a rural case study in the United Kingdom: Upton-upon-Severn. Remotely sensed data have been processed and assembled to provide an excellent test data set for both model construction and validation. In order to assess the usefulness of the data and the issues encountered in their use, two models for floodplain inundation were constructed: one based on an industry standard one-dimensional approach and the other based on a simple two-dimensional approach. The results and their implications for the future use of remotely sensed data for predicting flood inundation are discussed. Key conclusions for the use of remotely sensed data are that care must be taken to integrate different data sources for both model construction and validation and that improvements in ground height data shift the focus in terms of model uncertainties to other sources such as boundary conditions. The differences between the two models are found to be of minor significance.
