'Sliabh in Irish place-names' in Nomina 32 (2009)

This article deals with one of the most common elements in names of Irish hills and mountains. The grammar, phonology, etymology, semantic range and chronology of the element are examined. Sliabh is particularly complex in terms of its semantic range, which includes the following senses: 1) a mountain or hill (standing alone or forming part of a range); 2) a range of hills or mountains; 3) an moor or area of upland. The word is present in the earliest attested stages of the Irish language, and there is some evidence for all three meanings in Old Irish, though senses 1 and 2 are best attested. It is suggested that the view advanced by MacBain and Thurneysen that sliabh is etymologically related to Eng. slope and that this reflects its original meaning is open to some doubt in view of the lack of evidence for this sense in early Irish and the lack of clear cognates in other branches of Celtic and Indo-European languages.

Effect of interleukin-6 polymorphisms on human longevity:a systematic review and meta-analysis

Several studies have assessed changes in frequency of -174 interleukin (IL)-6 single nucleotide polymorphism (SNP) with age. If IL-6 tracks with disability and age-related diseases, then there should be reduction, in the oldest old, of the frequency of homozygous GG subjects, who produce higher IL-6 levels. However, discordant results have been obtained. To explore the relationship between this polymorphism and longevity, we analyzed individual data on long-living subjects and controls from eight case-control studies conducted in Europeans, using meta-analysis. There was no significant difference in the IL-6 genotype between the oldest old and controls (Odds Ratio [OR]=0.96; 95% C.I.: 0.77-1.20; p=0.71), but there was significant between-study heterogeneity (I2=55.5%). In a subgroup analyses when male centenarians from the three Italian studies were included, the frequency of the IL-6 -174 GG genotype was significantly lower than the other genotypes (OR=0.49; 95% C.I.: 0.31-0.80; p=0.004), with no evidence of heterogeneity (I2=0%). Our data supports a negative association between the GG genotype of IL-6 SNP and longevity in Italian centenarians, with males who carry the genotype being two times less likely to reach extreme old age compared with subjects carrying CC or CG genotypes. These findings were not replicated in other European groups suggesting a possible interaction between genetics, sex and environment in reaching longevity.

A genome-wide association study of anorexia nervosa

Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3). Individual association analyses were conducted in each stratum and meta-analyzed across all 15 discovery data sets. Seventy-six (72 independent) single nucleotide polymorphisms were taken forward for in silico (two data sets) or de novo (13 data sets) replication genotyping in 2677 independent AN cases and 8629 European ancestry controls along with 458 AN cases and 421 controls from Japan. The final global meta-analysis across discovery and replication data sets comprised 5551 AN cases and 21 080 controls. AN subtype analyses (1606 AN restricting; 1445 AN binge-purge) were performed. No findings reached genome-wide significance. Two intronic variants were suggestively associated: rs9839776 (P=3.01 × 10(-7)) in SOX2OT and rs17030795 (P=5.84 × 10(-6)) in PPP3CA. Two additional signals were specific to Europeans: rs1523921 (P=5.76 × 10(-)(6)) between CUL3 and FAM124B and rs1886797 (P=8.05 × 10(-)(6)) near SPATA13. Comparing discovery with replication results, 76% of the effects were in the same direction, an observation highly unlikely to be due to chance (P=4 × 10(^-6)), strongly suggesting that true findings exist but our sample, the largest yet reported, was underpowered for their detection. The accrual of large genotyped AN case-control samples should be an immediate priority for the field.

Release of β-galactosidase from poloxamine/α-cyclodextrin hydrogels

All mammals lose their ability to produce lactase (β-galactosidase), the enzyme that cleaves lactose into galactose and glucose, after weaning. The prevalence of lactase deficiency (LD) spans from 2 to 15% among northern Europeans, to nearly 100% among Asians. Following lactose consumption, people with LD often experience gastrointestinal symptoms such as abdominal pain, bowel distension, cramps and flatulence, or even systemic problems such as headache, loss of concentration and muscle pain. These symptoms vary depending on the amount of lactose ingested, type of food and degree of intolerance. Although those affected can avoid the uptake of dairy products, in doing so, they lose a readily available source of calcium and protein. In this work, gels obtained by complexation of Tetronic 90R4 with α-cyclodextrin loaded with β-galactosidase are proposed as a way to administer the enzyme immediately before or with the lactose-containing meal. Both molecules are biocompatible, can form gels in situ, and show sustained erosion kinetics in aqueous media. The complex was characterized by FTIR that evidenced an inclusion complex between the polyethylene oxide block and α-cyclodextrin. The release profiles of β-galactosidase from two different matrices (gels and tablets) of the in situ hydrogels have been obtained. The influence of the percentage of Tetronic in media of different pH was evaluated. No differences were observed regarding the release rate from the gel matrices at pH 6 (t50 = 105 min). However, in the case of the tablets, the kinetics were faster and they released a greater amount of 90R4 (25%, t50 = 40–50 min). Also, the amount of enzyme released was higher for mixtures with 25% Tetronic. Using suitable mathematical models, the corresponding kinetic parameters have been calculated. In all cases, the release data fit quite well to the Peppas–Sahlin model equation, indicating that the release of β-galactosidase is governed by a combination of diffusion and erosion processes. It has been observed that the diffusion mechanism prevails over erosion during the first 50 minutes, followed by continued release of the enzyme due to the disintegration of the matrix.

The Long Aftermath: Cultural Legacies of Europe at War, 1936-2016

In its totality, the “Long Second World War”—extending from the beginning of the Spanish Civil War to the end of hostilities in 1945—has exerted enormous influence over European culture. Bringing together leading historians, sociologists, and literary and film scholars, this broadly interdisciplinary volume investigates Europeans’ individual and collective memories and the ways in which they have shaped the continent’s cultural heritage. Focusing on the major combatant nations—Spain, Britain, France, Italy, Germany, Poland, and Russia—it offers thoroughly contextualized explorations of novels, memoirs, films, and a host of other cultural forms to illuminate European public memory.

Institutional Frameworks and Structural Factors Relating to Educational Access Across Europe

In this article institutional and structural factors relating to access to education are assessed. First, the macro frameworks of institutional regulation that exert influence on the educational trajectories of young Europeans are demonstrated. Based on different aspects of these frameworks and drawing from extant research, the article presents a typology of education systems that provide varying levels of access to and accessibility of education in Finland, France, Germany, Italy, Poland, the Netherlands, Slovenia, and the United Kingdom. Second, using survey data (N = 6,366) it analyzes the impact of gender and parental education on young people’s educational aspirations and early labor-market entry across the countries.

Global mitochondrial DNA phylogeography and population structure of the silky shark, Carcharhinus falciformis

Globally, sharks are under enormous pressure from fishing efforts. One such species is the silky shark, Carcharhinus falciformis, which occurs in all the Earth’s tropical oceans and is captured in large numbers in pelagic fisheries. Regionally, the silky shark is listed as Vulnerable to Near Threatened by the International Union for the Conservation of Nature due to high levels of direct and by catch exploitation. Despite major conservation concerns about this species, little is known about its genetic status and level of demographic or evolutionary connectivity among its regional distributions. We report a genetic assessment of silky sharks sampled across a major portion of the species’ global range. We sequenced the complete mitochondrial DNA control region from 276 individuals taken from the western Atlantic and Indo-Pacific Oceans and the Red Sea. Overall, haplotype and nucleotide diversities were relatively large (0.93 ± 0.01 and 0.61 ± 0.32 %, respectively). Nucleotide diversity in Indo-Pacific sharks, however, was significantly lower and about half that in Atlantic sharks. Strong phylogeographic partitioning occurred between ocean basins. Furthermore, shallow but significant pairwise statistical differentiation occurred among most regional samples within the Indo-Pacific, but not the western Atlantic. Overall, at least five mitochondrial DNA populations of silky sharks were identified globally. Despite historically large population sizes, silky sharks appear to be isolated on relatively small spatial scales, at least in the Indo-Pacific, indicating that conservation and management efforts will need to be exerted at relatively small scales in a pelagic and highly vagile species.

Neolithic and Bronze age migration to Ireland and establishment of the insular Atlantic genome

The Neolithic and Bronze Age transitions were profound cultural shifts catalyzed in parts of Europe by migrations, first of early farmers from the Near East and then Bronze Age herders from the Pontic Steppe. However, a decades-long, unresolved controversy is whether population change or cultural adoption occurred at the Atlantic edge, within the British Isles. We address this issue by using the first whole genome data from prehistoric Irish individuals. A Neolithic woman (3343–3020 cal BC) from a megalithic burial (10.3× coverage) possessed a genome of predominantly Near Eastern origin. She had some hunter–gatherer ancestry but belonged to a population of large effective size, suggesting a substantial influx of early farmers to the island. Three Bronze Age individuals from Rathlin Island (2026–1534 cal BC), including one high coverage (10.5×) genome, showed substantial Steppe genetic heritage indicating that the European population upheavals of the third millennium manifested all of the way from southern Siberia to the western ocean. This turnover invites the possibility of accompanying introduction of Indo-European, perhaps early Celtic, language. Irish Bronze Age haplotypic similarity is strongest within modern Irish, Scottish, and Welsh populations, and several important genetic variants that today show maximal or very high frequencies in Ireland appear at this horizon. These include those coding for lactase persistence, blue eye color, Y chromosome R1b haplotypes, and the hemochromatosis C282Y allele; to our knowledge, the first detection of a known Mendelian disease variant in prehistory. These findings together suggest the establishment of central attributes of the Irish genome 4,000 y ago.

Biomimética como conceito para uma embarcação na Ria de Aveiro

A Natureza é composta por estruturas, formas, sistemas, cores e até padrões que podem proporcionar ao design referências úteis e precisas, para que este consiga tornar os seus produtos e processos ecologicamente sustentáveis, indo de encontro com as necessidades ambientais que a sociedade humana atualmente se depara. A disciplina que utiliza estes fundamentos define-se pelo nome de Biomimética, temática escolhida para abordagem deste estudo. Partindo da região de Aveiro, e em específico a escolha da Ria, este espaço apresenta-se como um pretexto para a criação de uma embarcação Biomimética que funcione através do esforço físico do utilizador, revelando-se na hipótese de investigação proposta por este trabalho. O estudo incide sobre conceitos e definições em relação à Biomimética, bem como a ecologia, sustentabilidade, ergonomia e mercado, abordando uma base teórica fundamental para o estudo do tema proposto. A esse nível aprofundou-se questões relacionadas à construção de uma embarcação tendo em conta três pilares que se considera fundamentais: a inspiração das formas de diversos animais, e ainda a sua propulsão, o movimento mais adequado para este produto; finalizando com o estudo do mercado na pesquisa de referências reais na procura da forma. O resultado deste estudo culmina na realização de um protótipo à escala real em fibra de vidro, com o intuito de demonstrar o seu funcionamento, constatando a viabilidade na sua forma de deslocação.

Exploring the micro-politics of place: lifestyle migrants, collective identities and modes of belonging

Taking up Hopkins and Dixon’s (2006) call to attend to the micro-politics of everyday constructions of space and place, which necessarily involves psychological concepts such as identity, belonging and attachment, this paper aims to show how a critical socio-cognitive approach to discourse analysis is an effective means of unpacking the ways in which versions of place are (re)produced and negotiated through discursive practices, and in particular the ways in which ‘legitimate’ collective identities are constructed in relation to place. I focus on the contemporary social phenomenon of lifestyle migration. Within Europe, this typically involves relatively affluent northern Europeans moving to destinations in southern Europe that are strongly linked to tourism. Although lifestyle migrants are generally viewed by their hosts as ‘desirable’ migrants due to their perceived economic and socio-cultural capital, their integration into destination communities is often minimal. The question arises as to how these migrants construct modes of belonging in relation to their adopted home-place and how they relate to the other social groups with whom they share it. Using texts from a variety of sources, including in-depth interviews with British migrants in Portugal, I explore not only how migrants position themselves (and others) discursively in relation to places, but also how they are already positioned by discursive practices in the public sphere. I also examine to what extent the construction of a ‘legitimate’ mode of belonging involves the construction of intergroup cooperation within that place.

Corporate social marketing: um estudo de caso no setor da energia elétrica

Grupos privados que comercializam eletricidade ao setor residencial estão, atualmente, a implementar programas que procuram alcançar Eficiência Energética (EE). Estes programas levam a um menor consumo do produto core destas empresas. A EE é um tema destacado na atualidade, nações de todo o mundo traçam planos para alcançá-la, indo ao encontro do estabelecido no Protocolo de Quioto. Em Portugal, o setor da energia elétrica encontra-se entre os que mais danos acarretam para o ambiente. O presente estudo quis conhecer a orientação destes grupos nestes programas. Ou seja, conhecer a sua motivação para os implementar, bem como conhecer a abordagem disciplinar utilizada para os “desenhar”, procurando saber até que ponto o Corporate Social Marketing (CSM) é aplicado. O CSM utiliza a tecnologia do Marketing mainstream para alcançar mudanças comportamentais desejadas. Visa o bem-estar social e/ou ambiental e mede os resultados que atinge. A sua aplicação em programas que visam a EE no consumo, tratando-a como um produto social, é o foco da presente pesquisa. Para o efeito delineou-se a pesquisa através da metodologia Estudo de Caso, com o objetivo de estudar a orientação do Grupo EDP nestes programas, através do programa A Tua Energia, sabendo que “os projetos de Eficiência Energética são sempre definidos e implementados pela EDP enquanto Grupo” (EDP, 2012). A metodologia de análise de dados utilizada é a Grounded Theory (GT) que procura ir ao encontro de uma teoria substantiva, emersa dos dados, que se enquadre ao contexto da pesquisa. O Estudo da orientação do Grupo EDP levou a pesquisa a conhecer a realidade do setor elétrico em relação a estes programas, não só em Portugal mas noutro mercado onde a empresa EDP atua, o Brasil. Os principais resultados alcançados quanto à motivação dos Grupos privados para implementar estes programas foram Ganhos Empresariais, nos quais se integram Imagem Positiva, Estratégia de Negócio e Relacionamento com Stakeholders. Os dados revelam que o programa A Tua Energia não é um programa de CSM pois ainda que foque a mudança comportamental não a alcança efetivamente. Já a EDP no Brasil implementa um programa de mudança comportamental assente na abordagem do CSM. Concluiu-se que a envolvente influencia a orientação da EDP nestes programas, ainda que estes sejam designados pela EDP enquanto Grupo.
