There is considerable interest in alcohol in Irish society, yet minimal sociologcial understanding of its consumption, particularly of the sites where most drinking occurs: the country's 8750 pubs. Despite widespread public discussions on the role of the pub, there is scant social science evidence to better inform debate. Pubs are central to Irish community and are key sites of social interaction. American sociologist Ray Oldenburg has argued that "third places" (neither workplace nor home) are crucial to the maintenance of the community and the enhancement of social capital. According to Oldenburg, the role of the third place in the community is to provide continuity, regularity, a sense of place - all of which conceptually contribute to the construction of the self, the projection of the self within the public sphere, the distribution of social capital and the generation of a collective identity. The pub is the archetypal third place, but Oldenburg is concerned that modern pubs are less able to provide this vital function. Social scientists have suggested that community is in a state of fragmentation and decline due to changes in modes of social interaction and a decrease in shared spaces, resulting in a weakened connection to place. Community without propinquity has been characterised by social alienation, fragmentation and what Oldenburg refers to as the "problem of place" (13). Third places, and thus the Irish pub, have been particularly affected. In order to increase the sociological knowledge of the pub in Ireland, this project critically engages with the pub to assess the importance that public drinking houses have in the everyday. Moreover, this research sets out to investigate the people/place relationship using the pub as an investigative lens and examine the ways in which people shape place, place shapes people and how that relationship is implicated in the construction of irish identities. Furthermore, this is also an articulation of a cultural shift within Ireland and Irish places whose effects are deep and multi-layered. This project aims to explore the development of the contemporary geography of identity as the irish pub as a third place is transformed or disappears from the social landscape.

RESUMO Padrões de riqueza de espécies, abundância, diversidade, equitabilidade e dominância, além da organização em guildas tróficas e comportamentais da fauna de Scarabaeinae foram analisados em três diferentes fitofisionomias (floresta, campo natural e lavoura) na região noroeste do estado do Rio Grande do Sul, Brasil, entre setembro e novembro de 2012, através da utilização de armadilhas de queda iscadas com distintos recursos (fezes, carne em decomposição e banana fermentada). Foram capturados 9.325 espécimes, distribuídos em nove gêneros e 32 espécies. As espécies mais abundantes foram Onthophagus aff.tristis Harold, 1873, Canthidium aff.trinodosum (Boheman, 1858), Canthon aff.fallax Harold, 1868, Canthon lividusBlanchard, 1845 e Deltochilum morbillosum Burmeister, 1848 que representaram 65,54% do total de indivíduos amostrados. A floresta apresentou os valores mais elevados de número de indivíduos e de espécies. A menor riqueza foi observada no campo, enquanto a lavoura apresentou a menor abundância de indivíduos. Scarabaeinae apresentou diferenças quali- e quantitativas em suas assembleias pelas fitofisionomias amostradas. A floresta abrigou a maior riqueza observada de espécies e uma fração destas é exclusiva deste ambiente, e dificilmente ocorre em outros tipos de ecossistemas. A floresta apresentou uma proporção maior de espécies generalistas ou copro-necrófagas em sua composição. Outra parte desta fauna, representada por espécies coprófagas, está adaptada ao ambiente aberto indicando uma modificação na guilda alimentar causada pela substituição da floresta por pastagem. Dessa forma, em um contexto mais amplo a paisagem pode desempenhar um papel importante na diversidade de Scarabaeinae.

The paper is divided into four sections. The first offers a critical assessment of explanations of both rationalist and constructivist approaches currently dominating European studies and assesses the notion of path dependence. The second and third sections analyse the role of both material interests and polity ideas in EU enlargement to Turkey, and conclude that explanations exclusively based on either strategic calculations or values and identities have significant shortcomings. The fourth section examines the institutional path of Turkey's candidacy to show how the course of action begun at Helsinki restricted the range of possible and legitimate options three years later in Copenhagen.

The main motivation for exploring the relationship between globalization and Europeanization is the understanding of the importance of exogenous factors for policy change at the domestic level. Can we distinguish the impact of Europeanization to that of globalization? What is the relationship between globalization and Europeanization and what can we learn about the impact of the two phenomena upon political institutions, public policies, identities and values of EU member-states? Can we distinguish the traces of globalization to those of Europeanization upon the domestic level? The paper draws upon International Relations and International Political Economy theories of globalization as well as upon the Europeanization literature. Both phenomena are multi-dimensional and in order to assess their impact and their relationship three dimensions are explored: political institutions, public policies and values and identities. It is concluded that the two phenomena are interwoven and that there is no antithetical relationship between them. Their core is similar, based on the values of neo-liberalism, representative democracy and open market economy.

A composição e estratificação da atividade Phlebotominae desenvolvida numa mata residual e área aberta com intensa atividade agrícola, tomam parte desta investigação. O emprego da armadilha CDC tornou acessivo determinar a fauna local. Treze espécies e um número global de 5.423 indivíduos foram capturados. Os pontos situados no ecótono foram os que apresentaram maiores rendimentos, com destaque para P. intermedius, L. migonei e L. fischeri. Desse modo, os resultados levam acreditar serem portadoras de hábito acrodendrófilo. Por outro lado, quando o resultado global foi agrupado segundo o sexo masculino e feminino, o primeiro foi predominante. A análise da distruição estacional dessas espécies citadas revelou claramente picos de atividades mais elevados, bi e tri-modal, para diferentes estações. Na estação outono, P. intermedius teve atividade quase exclusivamente ao nível do solo. Esta exclusividade praticamente se estendeu aos locais de coleta situados em campo aberto.

BACKGROUND: This study describes the prevalence, associated anomalies, and demographic characteristics of cases of multiple congenital anomalies (MCA) in 19 population-based European registries (EUROCAT) covering 959,446 births in 2004 and 2010. METHODS: EUROCAT implemented a computer algorithm for classification of congenital anomaly cases followed by manual review of potential MCA cases by geneticists. MCA cases are defined as cases with two or more major anomalies of different organ systems, excluding sequences, chromosomal and monogenic syndromes. RESULTS: The combination of an epidemiological and clinical approach for classification of cases has improved the quality and accuracy of the MCA data. Total prevalence of MCA cases was 15.8 per 10,000 births. Fetal deaths and termination of pregnancy were significantly more frequent in MCA cases compared with isolated cases (p < 0.001) and MCA cases were more frequently prenatally diagnosed (p < 0.001). Live born infants with MCA were more often born preterm (p < 0.01) and with birth weight < 2500 grams (p < 0.01). Respiratory and ear, face, and neck anomalies were the most likely to occur with other anomalies (34% and 32%) and congenital heart defects and limb anomalies were the least likely to occur with other anomalies (13%) (p < 0.01). However, due to their high prevalence, congenital heart defects were present in half of all MCA cases. Among males with MCA, the frequency of genital anomalies was significantly greater than the frequency of genital anomalies among females with MCA (p < 0.001). CONCLUSION: Although rare, MCA cases are an important public health issue, because of their severity. The EUROCAT database of MCA cases will allow future investigation on the epidemiology of these conditions and related clinical and diagnostic problems.

BackgroundThe great diversity of bat haemosporidians is being uncovered with the help of molecular tools. Yet most of these studies provide only snapshots in time of the parasites discovered. Polychromophilus murinus, a malaria-like blood parasite, specialised on temperate-zone bats is a species that is being `rediscovered¿. This study describes the infection dynamics over time and between host sex and age classes.MethodsFor three years we followed the members of three breeding colonies of Myotis daubentonii in Western Switzerland and screened them for the prevalence and parasitemia of P. murinus using both molecular tools and traditional microscopy. In order to identify more susceptible classes of hosts, we measured, sexed and aged all individuals. During one year, we additionally measured body temperature and haematocrit values.ResultsJuvenile bats demonstrated much higher parasitemia than any other age class sampled, suggesting that first exposure to the parasite is very early in life during which infections are also at their most intense. Moreover, in subadults there was a clear negative correlation between body condition and intensity of infection, whereas a weak positive correlation was observed in adults. Neither body temperature, nor haematocrit, two proxies used for pathology, could be linked to intensities of infection.ConclusionIf both weaker condition and younger age are associated with higher infection intensity, then the highest selection pressure exerted by P. murinus should be at the juvenile stage. Confusion over the identities and nomenclature of malarial-like parasites requires that molecular barcodes are coupled to accurate morphological descriptions.

Only few cases of classical phenylketonuria (PKU) in premature infants have been reported. Treatment of these patients is challenging due to the lack of a phenylalanine-free amino acid solution for parenteral infusion. The boy was born at 27 weeks of gestation with a weight of 1000 g (P10). He received parenteral nutrition with a protein intake of 3 g/kg/day. On day 7 he was diagnosed with classical PKU (genotype IVS10-11G>A/IVS12+ 1G>A) due to highly elevated phenylalanine (Phe) level in newborn screening (2800 micromol/L). His maximum plasma Phe level reached 3696 micromol/L. Phe intake was stopped for 4 days. During this time the boy received intravenous glucose and lipids as well as little amounts of Phe-free formula by a nasogastric tube. Due to a deficit of essential amino acids and insufficient growth, a parenteral nutrition rich in branched-chain amino-acids and relatively poor in Phe was added, in order to promote protein synthesis without overloading in Phe. Under this regimen, Phe plasma levels normalized on day 19 when intake of natural protein was started. The boy has now a corrected age of 2 years. He shows normal growth parameters and psychomotor development. Despite a long period of highly elevated Phe levels in the postnatal period our patient shows good psychomotor development. The management of premature infants with PKU depends on the child's tolerance to enteral nutrition. It demands an intensive follow-up by an experienced team and dedicated dietician. Appropriate Phe-free parenteral nutrition would be necessary especially in case of gastro-intestinal complications of prematurity.
