The purpose of this White Paper is to set out Government policy on all issues relating to early childhood education. An essential starting point is to define what we mean by early childhood education. The Department of Education and Science�s mission is to support the development of a high quality education system which will enable individuals to develop to their full potential as persons and to participate fully as citizens in Ireland�s social and economic development. For many years, it was considered that education began when children went to school and ended when students left the formal education system at the end of first, second or third level. There is growing recognition of the importance of lifelong learning and the idea that children learn from the earliest moment and continue to learn throughout their lives. Education is concerned with all the phases of life, including the very early childhood phase.

This is Ireland’s first White Paper on Adult Education and marks the adoption of lifelong learning as the governing principle of educational policy. The Paper reflects on the role of adult education in society, builds on the consultation process following publication of the Green Paper, and sets out the Government’s policies and priorities for the future development of the sector. It does not aim to provide a policy blueprint for the training sector given that this work is being advanced through the National Employment Action Plans and previous publications, and the work of the Task Force on Lifelong Learning recently established by the Department of Enterprise, Trade and Employment. Rather, it seeks to ensure that there is a fit and complementarity between education and training provision, so as to ensure that learners can move progressively and incrementally within an over-arching co-ordinated and learner-centred framework.

Laser desorption ionisation mass spectrometry (LDI-MS) has demonstrated to be an excellent analytical method for the forensic analysis of inks on a questioned document. The ink can be analysed directly on its substrate (paper) and hence offers a fast method of analysis as sample preparation is kept to a minimum and more importantly, damage to the document is minimised. LDI-MS has also previously been reported to provide a high power of discrimination in the statistical comparison of ink samples and has the potential to be introduced as part of routine ink analysis. This paper looks into the methodology further and evaluates statistically the reproducibility and the influence of paper on black gel pen ink LDI-MS spectra; by comparing spectra of three different black gel pen inks on three different paper substrates. Although generally minimal, the influences of sample homogeneity and paper type were found to be sample dependent. This should be taken into account to avoid the risk of false differentiation of black gel pen ink samples. Other statistical approaches such as principal component analysis (PCA) proved to be a good alternative to correlation coefficients for the comparison of whole mass spectra.

Joint discussion paper funded by the Alzheimer Society of Ireland and authored by the Institute of Public Health Approximately 47,849 people were living with dementia in Ireland in 2011. This number is expected to double by 2031 to about 90,000 as incident rates of dementia are set to rise with population ageing (Pierce et. al. 2014). Although much remains to be established at a causal level, epidemiological research indicates that there is scope for reducing dementia prevalence and age-specific incidence through addressing modifiable risk factors. There is a growing consensus for the mobilisation of public health approaches to attempt to reduce the prevalence of dementia through primary prevention. This discussion paper presents a rapid review of evidence on the primary prevention of dementia and presents estimates for the number of dementia cases that could potentially be preventable through modifying specific risk factors in Ireland. The paper focuses only on primary prevention which relates to delaying or preventing the onset of dementia. Specifically, the discussion paper presents: a rapid review of the current evidence-base on dementia prevention internationally estimates of the number of dementia cases that might be prevented by addressing modifiable risk factors considerations for integrating a brain health and dementia prevention perspective into public health research, policy and practice in Ireland.

Public health services in Ireland, North and South, are committed to addressing inequalities in health on the island of Ireland. This report, prepared by Dr Lorraine Doherty, Assistant Director of Public Health (Health Protection), Public Health Agency NI for the Institute of Public Health in Ireland (IPH), specifically highlights health inequalities in relation to infectious diseases and other areas of health protection such as chemical hazards and environmental disruption. Infectious diseases disproportionately affect the most vulnerable in society. These vulnerable groups bear the highest burden of disease in relation to infectious diseases. The report also highlights the impact of climate change on health protection and the impacts for water, food and vector borne diseases. The aim of this report is to enable a programme of work to begin to document health protection inequalities and develop action plans for addressing them on an all island basis.

La intenció d'aquest article és detallar l'abast del capital social als esdeveniments culturals celebrats a Catalunya i analitzar la influència sobre l'atracció turística dels mateixos. Es pretén determinar també quin és l'impacte que tres elements de capital social que intervenen en l'organització d'esdeveniments (elements de motivació, creació de xarxes internes i lideratge) tenen sobre el sector turístic local. L'estudi parteix d'una mostra de 263 esdeveniments als quals s'ha adreçat una enquesta per determinar la presència i pes dels factors de capital social. Aquesta informació s'ha creuat amb dades sobre impactes i atracció turística obtingudes també a partir de la mateixa enquesta i, a partir de l'aplicació del test del chi quadrat, s'ha contrastat si les diferències existents entre els diferents factors del capital social són estadísticament significatives. Les conclusions principals obtingudes indiquen que els esdeveniments que tenen elements de capital social que els reforça la seva cohesió social entenen i justifiquen la celebració com a fet socialitzador, independentment del seu abast turístic. A més es detecta que la creació de xarxes de relació enforteix la cohesió interna, la representativitat i el sentit d'identitat de la comunitat. Finalment es constata que la presència d'elements de lideratge que donen visibilitat i vinculen l'esdeveniment amb xarxes externes explica la diferència existent en la capacitat d'atracció i impactes turístics dels esdeveniments. La principal aportació del treball és posar de manifest el paper del capital social com a factor que incideix en la repercussió social i turística dels esdeveniments catalans. La diagnosi efectuada permet recomanar la incorporació del capital social com un actiu estratègic per a la gestió i per a la creació de nous productes i polítiques turístiques centrades en els esdeveniments culturals.

In this paper we examine the problem of compositional data from a different startingpoint. Chemical compositional data, as used in provenance studies on archaeologicalmaterials, will be approached from the measurement theory. The results will show, in avery intuitive way that chemical data can only be treated by using the approachdeveloped for compositional data. It will be shown that compositional data analysis is aparticular case in projective geometry, when the projective coordinates are in thepositive orthant, and they have the properties of logarithmic interval metrics. Moreover,it will be shown that this approach can be extended to a very large number ofapplications, including shape analysis. This will be exemplified with a case study inarchitecture of Early Christian churches dated back to the 5th-7th centuries AD

Compositional data naturally arises from the scientific analysis of the chemicalcomposition of archaeological material such as ceramic and glass artefacts. Data of thistype can be explored using a variety of techniques, from standard multivariate methodssuch as principal components analysis and cluster analysis, to methods based upon theuse of log-ratios. The general aim is to identify groups of chemically similar artefactsthat could potentially be used to answer questions of provenance.This paper will demonstrate work in progress on the development of a documentedlibrary of methods, implemented using the statistical package R, for the analysis ofcompositional data. R is an open source package that makes available very powerfulstatistical facilities at no cost. We aim to show how, with the aid of statistical softwaresuch as R, traditional exploratory multivariate analysis can easily be used alongside, orin combination with, specialist techniques of compositional data analysis.The library has been developed from a core of basic R functionality, together withpurpose-written routines arising from our own research (for example that reported atCoDaWork'03). In addition, we have included other appropriate publicly availabletechniques and libraries that have been implemented in R by other authors. Availablefunctions range from standard multivariate techniques through to various approaches tolog-ratio analysis and zero replacement. We also discuss and demonstrate a smallselection of relatively new techniques that have hitherto been little-used inarchaeometric applications involving compositional data. The application of the libraryto the analysis of data arising in archaeometry will be demonstrated; results fromdifferent analyses will be compared; and the utility of the various methods discussed

In this paper we present first results of the study of planktonic Foraminifera, large benthic Foraminifera and carbonate facies of La Désirade, aiming at a definition of the age and depositional environments of the Neogene carbonates of this island. The study of planktonic Foraminifera from the Detrital Offshore Limestones (DOL) of the Anciènne Carrière allows to constrain the biochronology of this formation to the lower Zone N19 and indicates a latest Miocene to early Pliocene (5.48 - 4.52 Ma) age. Large benthic Foraminifera were studied both as isolated and often naturally split specimens from the DOL, and in thin sections of limestones from the DOL and the Limestone Table (LT). The assemblages of Foraminifera include Nummulitidae, Amphisteginidae, Asterigerinidae, Peneroplidae, Soritidae, Rotalidae (Globigerinidae: Globigerinoides, Sphaeroidenellopsis, Orbulina) and incrusting Foraminifera (Homotrema and Sporadotrema). The genera Amphistegina, Archaias and Operculina are discussed. Concerning the Nummulitidae we include both "Paraspiroclypeus" chawneri and "Nummulites" cojimarensis, as well as a newly described species, Operculina desiradensis new species, in the genus Operculina, because the differences between these 3 species are rather on the specific than the generic level, while their morphology, studied by SEM, is compatible with the definition of the genus Operculina (D'Orbigny1826, emend. Hottinger 1977). The three species can be easily distinguished on the basis of their differences in spiral growth: while O. desiradensis has an overall logarithmic spiral growth, O. cojimarensis and especially O. chawneri show a tighter and more geometric spiral growth. O. cojimarensis and O. chawneri were originally described from Cuba in outcrops originally dated as Oligocene and later redated as early Pliocene. Therefore, O. chawneri was considered until now as restricted to the early Pliocene. However, in the absence of a detailed morphometric and biostratigraphic study of the Caribbean Neogene nummulitids, it is difficult to evaluate the biochronologic range of these species.The history of the carbonates begins with the initial tectonic uplift and erosion of the Jurassic igneous basement of La Désirade, that must have occurred at latest in late Miocene times, when sea-level oscillated around a long term stable mean. The rhythmic deposition of the Désirade Limestone Table (LT) can be explained by synsedimentary subsidence in a context of rapidly oscillating sea-level due to precession-driven (19-21 kyr) glacio-eustatic sea-level changes during the latest Miocene- Pliocene. Except for a thin reef cap present at the eastern edge of the LT, no other in-place reefal constructions have been observed in the LT. The DOL of western Désirade are interpreted as below wave base gravity deposits that accumulated beneath a steep fore-reef slope. They document the mobilisation of carbonate material (including Larger Foraminifera) from an adjacent carbonate platform by storms and their gravitational emplacement as debris and grain flows. The provenance of both the reefal carbonate debris and the tuffaceous components redeposited in the carbonates of La Désirade must be to the west, i. e. the carbonate platforms of Marie Galante and Grande Terre.

Objetivos: 1.-Identificar los factores clínicos y microbiológicos que ayuden a predecir la aparición de exacerbaciones en la EPOC. 2.-Diagnóstico y cuantificación de las especies bacterianas aisladas en esputo (fase de exacerbación y estable) .3.- Tipificación genotípica secuencial de las cepas de H. influenzae y P. aeruginosa. 4.- Impacto del tratamiento antibiótico en la aparición de resistencias en estos patógenos. 5.- Diseño: Estudio prospectivo (3 años). Ámbito del estudio: Hospital Universitario de tercer nivel. Pacientes con EPOC grave atendidos en la Consulta Monográfica de EPOC del Servicio de Neumología. Métodos microbiológicos: Cuantificación de la carga bacteriana en muestras respiratorias en fase estable y en exacerbación. Estudio de la sensibilidad “in vitro”. Tipificación molecular (PFGE y MLST) de H. influenzae y P. aeruginosa. Estudio de los genes de virulencia de H. influenzae mediante PCR. Resultados: Desde Febrero de 2010 a Julio de 2011 se han incluido 77 pacientes. Los microorganismos más frecuentemente aislados en fase de exacerbación fueron: P. aeruginosa (29.3%), H. influenzae (15.92%), M. catarrhalis (12.74%), S. pneumoniae (10.19%) y S. aureus (5.10%). En los 88 episodios por P. aeruginosa se detectaron 38 genotipos diferentes. En los 41 episodios por H. influenzae se detectaron 39 genotipos diferentes. El 10% de los episodios fueron polimicrobianos. Los episodios de EAEPOC y de fase estable tuvieron una distribución de microorganismos similar. Sin embargo, cuando se cuantificaron las cargas bacterianas fueron mayores en EAEPOC (intervalo 4x107 -2x108) que en fase estable (intervalo 2x105 -4x107). Conclusiones: El genotipo de las cepas de P. aeruginosa y H. influenzae aisladas en EAEPOC difieren de un paciente a otro, sin embargo la mayoría de los episodios de cada paciente están causados por un genotipo único.
