The Minister for Health requested the Chief Medical Officer to prepare a Report for him on issues that arose following a Primetime Investigates programme relating to Portlaoise Hospital Maternity Services (PHMS) on 30th January 2014. This Report provides a preliminary assessment of PHMS focusing on perinatal deaths (2006-date) and related matters. Through a series of recommendations it sets out the need for further examination or actions where the findings of this preliminary assessment suggest such a need. It also makes clear who should be responsible for these further examinations or actions. Â Download the Report

In spite of the fact that the Ars predicandi populo is attributed to Eiximenis in only one of the three extant manuscripts, there is no doubt that it is one of his works.First of all, the internal references to this treatise in the pages of Terç and Dotzè del Crestià are an irrefutable testimony and, secondly, the presence of an autographvolume of sermons which begins with the Ars in the inventory of the Eiximenis library made shortly after his death. The writing of the Ars and the collection of sermons which introduces it must be dated prior to the beginning of the Crestià encyclopedia (1379) because of the complexity that entailed the writing of a collection of three perhaps four volumes of sermons. Due to a series of formal and codicological reasons it must be concluded that the chapter entitled De consiliis circa predicacionem cannot be attributed to Eiximenis and thus be excluded from the Ars

We investigated how territory quality, settlement date and morphometry affected several components of yearly breeding success of a Swiss population of Savi's Warblers Locustella luscinioides. Territories occupied by males differed from unoccupied sites of similar size and location by having higher and denser reeds, a more extensive straw litter, and a thicker cover of dead sedge leaves. Territories with these characteristics were the ones first chosen by males upon spring arrival. These males, however, did not differ in morphometry from those that arrived later. Availability of suitable nesting sites; rather than food availability, appears to be an important choice criterion for territories. Early arriving males had higher breeding success than late males because of a higher mating success and more successful clutches. The positive correlation between male breeding success and territory quality was thus mediated through their common dependence on occupancy date. Female breeding success decreased with the date of first-clutch laying, mainly because late-nesting females fledged fewer broods. Breeding success in either sex did not correlate with morphometry. Our results provide clear support for territory choice by males, but not for mate or territory choice by females, and show the crucial role played by individual settlement date on many aspects of the breeding cycle of both sexes. We propose a lottery model of mate choice. arriving females obtain the best available territories even without choosing mates or territories; since males occupy territories sequentially and in order of decreasing quality, the few unpaired males available at any moment also occupy the best available territories.

Ectoparasites are common in most bird species, but experimental evidence of their effects on life-history traits is scarce. We investigated experimentally the effects of the hematophagous hen flea (Ceratophyllus gallinae) on timing of reproduction, nest-site choice, nest desertion, clutch size, and hatching success in the great tit (Parus major). When great tits were offered a choice on their territory between an infested and a parasite-free nest-box, they chose the one without parasites. When there was no choice, the great tits in a territory containing an infested nest-box delayed laying the clutch by 11 days as compared with the birds that were offered a parasite-free nesting opportunity. The finding that there was no difference in phenotypic traits related to dominance between the birds nesting in infested boxes and birds nesting in parasite-free boxes suggests that the delay is not imposed by social dominance. Nest desertion between laying and shortly after hatching was significandy higher in infested nests. There was no difference between infested and parasite-free nests in clutch size, but hatching success and hence brood size at hatching were significantly smaller in infested nests. Nest-box studies of great tits have been seminal in the development of evolutionary, ecological, and behavioral theory, but recently a polemic has arisen in the literature about the validity of the conclusions drawn from nest-box studies where the naturally occurring, detrimental ectoparasites are eliminated by the routine removal of old nests between breeding seasons. Our study suggests that this criticism is valid and that the evaluation of the effects of ectoparasites may improve our understanding of behavioral traits, life-history traits, or population dynamics
