An Index of Child Well-being in the European Union

While the living conditions of children and young people in the European Union have gained increasing recognition across the EU, the well-being of children is not monitored on the European level. Based on a rights-based, multi-dimensional understanding of child well-being we analyse data already available for the EU 25, using series data as well as comparative surveys of children and young people. We compare the performance of EU Member States on eight clusters with 23 domains and 51 indicators and give a picture of children’s overall well-being in the European Union. The clusters are children’s material situation, housing, health, subjective well-being, education, children’s relationships, civic participation and risk and safety

Polyglot Semantic Parsing in APIs

Traditional approaches to semantic parsing (SP) work by training individual models for each available parallel dataset of text-meaning pairs. In this paper, we explore the idea of polyglot semantic translation, or learning semantic parsing models that are trained on multiple datasets and natural languages. In particular, we focus on translating text to code signature representations using the software component datasets of Richardson and Kuhn (2017a,b). The advantage of such models is that they can be used for parsing a wide variety of input natural languages and output programming languages, or mixed input languages, using a single unified model. To facilitate modeling of this type, we develop a novel graph-based decoding framework that achieves state-of-the-art performance on the above datasets, and apply this method to two other benchmark SP tasks.Comment: accepted for NAACL-2018 (camera ready version

Uncertainty of flow in porous media

The problem posed to the Study Group was, in essence, how to estimate the probability distribution of f(x) from the probability distribution of x. Here x is a large vector and f is a complicated function which can be expensive to evaluate. For Schlumberger's applications f is a computer simulator of a hydrocarbon reservoir, and x is a description of the geology of the reservoir, which is uncertain

Towards the ‘Big Society’: What role for neighbourhood working? Evidence from a comparative European study

Under the New Labour government, the neighbourhood emerged prominently as a site for policy interventions and as a space for civic activity, resulting in the widespread establishment of neighbourhood-level structures for decision-making and service delivery. The future existence and utility of these arrangements is now unclear under the Coalition government's Big Society proposals and fiscal austerity measures. On the one hand, sub-local governance structures might be seen as promoting central-to-local and local-to-community devolution of decision-making. On the other, they might be seen as layers of expensive bureaucracy standing in the way of bottom-up community action. Arguably the current value and future role of these structures in facilitating the Big Society will depend on how they are constituted and with what purpose. There are many local variations. In this paper we look at three case studies, in England, France and the Netherlands, to learn how different approaches to neighbourhood working have facilitated and constrained civic participation and action. Drawing on the work of Lowndes and Sullivan (2008) we show how the achievement of civic objectives can be hampered in structures set up primarily to achieve social, economic and political goals, partly because of (remediable) flaws in civic engagement but partly because of the inherent tensions between these objectives in relation to issues of spatial scale and the constitution and function of neighbourhood structures. The purpose of neighbourhood structures needs to be clearly thought through. We also note a distinction between 'invited' and 'popular' spaces for citizen involvement, the latter being created by citizens themselves. 'Invited' spaces have tended to dominate to date, and the Coalition's agenda suggests a fundamental shift to 'popular' spaces. However we conclude that the Big Society will require neighbourhood working to be both invited and popular. Citizen participation cannot always replace local government - sometimes it requires its support and stimulation. The challenge for local authorities is to reconstitute 'invited' spaces (not to abolish them) and at the same time to facilitate 'popular' spaces for neighbourhood working.Big Society, local government, neighbourhood, neighbourhood management, community

An analysis and visualization of the output mode-matching requirements for squeezing in Advanced LIGO and future gravitational wave detectors

The sensitivity of ground-based gravitational wave (GW) detectors will be improved in the future via the injection of frequency-dependent squeezed vacuum. The achievable improvement is ultimately limited by losses of the interferometer electromagnetic field that carries the GW signal. The analysis and reduction of optical loss in the GW signal chain will be critical for optimal squeezed light-enhanced interferometry. In this work we analyze a strategy for reducing output-side losses due to spatial mode mismatch between optical cavities with the use of adaptive optics. Our goal is not to design a detector from the top down, but rather to minimize losses within the current design. Accordingly, we consider actuation on optics already present and one transmissive optic to be added between the signal recycling mirror and the output mode cleaner. The results of our calculation show that adaptive mode-matching with the current Advanced LIGO design is a suitable strategy for loss reduction that provides less than 2% mean output mode-matching loss. The range of actuation required is +47 uD on SR3, +140 mD on OM1 and OM2, +50 mD on the SRM substrate, and -50 mD on the added new transmissive optic. These requirements are within the demonstrated ranges of real actuators in similar or identical configurations to the proposed implementation. We also present a novel technique that graphically illustrates the matching of interferometer modes and allows for a quantitative comparison of different combinations of actuators.Comment: Matches version accepted in PR

A policy analysis of the Anglican and Roman Catholic school systems in England.

This is a study of the contemporary Anglican and Catholic school systems in England. It compares the main characteristics of each and seeks to establish how far these are attributable to characteristics of the churches themselves and the extent to which there is convergence between the two school systems as they and their churches respond to contemporary challenges. This is a complex subject, analysis of which is aided by a model developed from the work of Ball (1994) in the field of education policy studies. Using this model, the broader context in which church schools operate is analysed first, including especially the historical development of church schools, the educational requirements of modern government, the characteristics of the two churches in England as they have adapted to the social changes of the 20th century, together with the relevant aspects of those changes, particularly the secularisation of society. The relationship between this broad 'context of influence' and the contemporary church school systems is emphasised throughout this study. Against this background the Anglican and Catholic school systems are analysed and compared at two levels - the strategic level at which Official’ policy is produced and the school level at which it is implemented, with the relationship between the two levels examined in detail. The main features of the two systems are identified and analysed, together with each of the main areas of policy relating to church schools, using a classification system to assist the comparison between them. For example, the issue of pupil admissions is analysed in terms of the stated policies of each church at national and diocesan levels and examined in terms of application at school level in each system. Whilst this is a study of church schools nationally, it is illustrated where appropriate by a case study of Anglican and Catholic schools in the city of Liverpool. This study has demonstrated clearly that, despite many obvious similarities between the Anglican and Catholic school systems, they do indeed reflect a number of distinctive characteristics of each church. The study also suggests that these characteristics have made it easier for the Anglican system to adapt to the demands of the modern state and the secularisation of society than it has been for the Catholic system, not least because most Anglican schools have traditionally served children from any or no religious background. These differences, it is argued, help to explain the contrasting current approaches of the two churches to the possibilities for expandin

The Halo Occupation Distribution of X-ray-Bright Active Galactic Nuclei: A Comparison with Luminous Quasars

We perform halo occupation distribution (HOD) modeling of the projected two-point correlation function (2PCF) of high-redshift (z~1.2) X-ray-bright active galactic nuclei (AGN) in the XMM-COSMOS field measured by Allevato et al. The HOD parameterization is based on low-luminosity AGN in cosmological simulations. At the median redshift of z~1.2, we derive a median mass of (1.02+0.21/-0.23)x10^{13} Msun/h for halos hosting central AGN and an upper limit of ~10% on the AGN satellite fraction. Our modeling results indicate (at the 2.5-sigma level) that X-ray AGN reside in more massive halos compared to more bolometrically luminous, optically-selected quasars at similar redshift. The modeling also yields constraints on the duty cycle of the X-ray AGN, and we find that at z~1.2 the average duration of the X-ray AGN phase is two orders of magnitude longer than that of the quasar phase. Our inferred mean occupation function of X-ray AGN is similar to recent empirical measurements with a group catalog and suggests that AGN halo occupancy increases with increasing halo mass. We project the XMM-COSMOS 2PCF measurements to forecast the required survey parameters needed in future AGN clustering studies to enable higher precision HOD constraints and determinations of key physical parameters like the satellite fraction and duty cycle. We find that N^{2}/A~5x10^{6} deg^{-2} (with N the number of AGN in a survey area of A deg^{2}) is sufficient to constrain the HOD parameters at the 10% level, which is easily achievable by upcoming and proposed X-ray surveys.Comment: 11 pages, 4 figures, accepted in Ap
