The signature of fine scale local adaptation in Atlantic salmon revealed from common garden experiments in nature

Understanding the extent, scale and genetic basis of local adaptation is important for conservation and management. Its relevance in salmonids at microgeographic scales, where dispersal (and hence potential gene flow) can be substantial, has however been questioned. Here we compare the fitness of communally-reared offspring of local and foreign Atlantic salmon Salmo salar from adjacent Irish rivers and reciprocal F1 hybrid crosses between them, in the wild ‘home’ environment of the local population. Experimental groups did not differ in wild smolt output but a catastrophic flood event may have limited our ability to detect freshwater performance differences, which were evident in a previous study. Foreign parr exhibited higher, and hybrids intermediate, emigration rates from the natal stream relative to local parr, consistent with genetically-based behavioural differences. Adult return rates were lower for the foreign compared to the local group. Overall lifetime success of foreigners and hybrids relative to locals was estimated at 31% and 40% (mean of both hybrid groups), respectively. The results imply a genetic basis to fitness differences among populations separated by only 50km, driven largely by variation in smolt to adult return rates. Hence even if supplementary stocking programs obtain broodstock from neighbouring rivers, the risk of extrinsic outbreeding depression may be high.

O conto literário de temática açoriana: a ilha, o mar e a emigração

O conto literário de temática açoriana reflecte uma visão do mundo particular, resultante de condições geográficas, geológicas, climáticas, sociais, históricas e culturais. A análise dos textos permitiu-nos detectar recorrências temáticas inspiradas em impressões e experiências reiteradas relacionadas com a realidade circundante, as quais requisitam, constantemente, a expressão literária. A ilha, perspectivada eufórica e disforicamente, o mar e a emigração constituem elementos centrais no imaginário açoriano. O presente trabalho identifica e estuda as imagens e os temas mais importantes na trajectória deste conto, mostrando até que ponto se pode falar de uma tradição literária açoriana no contexto da literatura portuguesa.

Famílias envelhecidas: percursos e diversidade

O conhecimento sobre famílias envelhecidas é ainda escasso. Neste âmbito, a pesquisa tem incidido nos cuidados familiares a idosos dependentes, focando os problemas de saúde, dependência funcional e declínio cognitivo. Esta investigação pretende contribuir para aprofundar o conhecimento sobre as famílias envelhecidas, assumindo uma perspetiva normativa e desenvolvimental, e contemplando a diversidade de contextos de vida e envelhecimento. O capítulo 1 centra casais compostos por pessoas idosas, e tem por objetivos: caracterizar a estrutura, dinâmica e valores do agregado familiar dos casais idosos; evidenciar valores e dinâmica relacional dos casais idosos. A amostra compreende 136 participantes, a quem foi administrado um questionário sobre a fase última do ciclo de vida familiar (Cerveny,1997). A análise de dados efetuou-se com recurso ao programa de análise de dados estatística SPSS 17.1. Os resultados indicam que os casais vivem predominantemente em casal, com uma dinâmica relacional do agregado caracterizada pelo respeito, diálogo e carinho; dinâmica relacional do casal caracterizada por clima afetuoso, amizade e diálogo, e valores assentes no amor, diálogo e convívio familiar. A dinâmica relacional do casal é pautada por atividades de lazer realizadas em conjunto e vida sexual tão boa como antes; os valores dão ao casamento significados de realização pessoal e perpetuação através dos filhos na juventude, e adaptação e descoberta na velhice. O capítulo 2 foca a construção da integridade familiar considerando a diversidade de contextos socioeconómicos (pessoas idosas que viveram em contexto de pobreza ao longo da vida), socioculturais (ex-emigrantes portugueses) e novas formas de famílias (homens homossexuais). Foi aplicada uma entrevista semiestruturada (King & Wynne, 2004) a uma amostra de 12, 20 e 10 pessoas, respetivamente. A análise de dados foi efetuada com base na análise de conteúdo com recurso a juízes independentes baseada na grounded theory, contudo no caso do contexto socioeconómico recorreu-se ao programa de análise de dados qualitativa N-Vivo 7. Os resultados sugerem que a diversidade de contextos analisada coloca desafios à rutura familiar o que pode potenciar o caminho da desconexão e alienação. Contudo, o contexto das significações exerce um papel fundamental na construção da integridade familiar. A redefinição da identidade associada a uma filosofia de vida que enfatize as forças em vez dos fracassos parece determinar a construção da integridade familiar, contudo existem especificidades. Relativamente ao contexto socioeconómico: as pessoas idosas no caminho da integridade revelam um sentido de autovalorização (ter vivido uma vida significativa) apesar da pobreza; as pessoas idosas no caminho da desconexão/alienação alimentam sentimentos de insignificância devido à escassez de recursos económicos. Ainda neste contexto, os valores (princípios de conduta) reinterpretam a identidade ao longo da vida e permitem compreender que a integridade familiar ocorre quando ser pobre é encarado pelas conquistas; a desconexão/alienação emerge quando ser pobre incorpora sentimentos de desvalorização e inferioridade. No contexto sociocultural, as pessoas idosas ex-emigrantes cujo processo de emigração se desenvolveu em família (a família está envolvida no processo de emigração e funciona como um pilar desde a fase de decisão até ao regresso) desenvolveram uma filosofia de vida assente numa atitude ativa e solidária e estão em integridade familiar; as pessoas em desconexão relatam episódios de conflito familiar que marcam a trajetória de emigração, e uma atitude passiva na resolução desses conflitos até à atualidade; as pessoas em alienação familiar, cujo processo de emigração se desenrolou de forma solitária, desenvolvem uma filosofia de vida assente na luta solitária: a sua força e identidade estão em enfrentar tudo sem precisar de ninguém. Relativamente às novas formas de família, a integridade familiar evolui desde a revelação da homossexualidade (em idade jovem) e conclui-se na velhice quando a homossexualidade se torna um legado. A desconexão parece evoluir da luta constante da falha da aceitação da homossexualidade pela família e outras pessoas significativas. O capítulo 3 analisa as trajetórias de vida de homens homossexuais atualmente idosos, para compreender melhor a influência da homossexualidade e os principais eventos. Adotou-se a técnica da linha de acontecimentos de vida (Acquaviva et al., 2007), aplicada a 10 participantes com 60 anos ou mais. Os resultados sugerem que vários eventos de vida influenciam o curso de vida: i) o autoconhecimento da homossexualidade; ii) tentar passar por heterossexual; iii) assumir a homossexualidade (explicita ou implicitamente); iv) sentir limitações e desafios relacionados com o ser idoso e homossexual. O capítulo 4 procurou alargar a perspetiva do envelhecimento considerando uma abordagem transcultural. Assim, realizou-se um estudo numa comunidade indígena (Guarani Mbya, Brasil). Neste estudo analisase o modo de viver e ser idoso nessa comunidade. A amostra compreende 6 participantes a quem foi administrada uma entrevista aberta. Este estudo contemplou ainda a observação com registo etnográfico e realização de um diário de bordo. A análise de conteúdo efetuou-se com apoio do software de dados qualitativa WebQDA 1.4.3. Os resultados sugerem o papel das pessoas idosas na preservação de uma cultura ágrafa, garantindo que as tradições estejam presentes nas gerações atuais através da oralidade. A adoção de lentes normativas no estudo e compreensão das famílias envelhecidas permite compreender as tarefas desenvolvimentais e normativas no fim da vida.

A internacionalização do setor bancário português

O processo de globalização, na esfera dos mercados financeiros, exigiu às instituições bancárias opções de investimento estratégico na plataforma internacional. O movimento de implantação dos bancos portugueses no estrangeiro acompanhou esse processo, permitindo a oferta de serviços bancários de captação e financiamento nos principais mercados de destino das exportações e emigração. A presente dissertação tem como objetivo o estudo do processo de internacionalização do setor bancário português centrado na seguinte questão geral de investigação: “Quais os fatores determinantes das variáveis que caraterizam a evolução do setor bancário português no exterior?” O desenvolvimento desta questão é conduzido através da construção de um modelo explicativo dos impactos de um conjunto de determinantes, selecionados a partir da revisão de literatura, sobre os indicadores que traduzem a dinâmica do negócio bancário no exterior. Neste contexto, pretendeu-se obter evidência empírica desses efeitos através de uma metodologia que consiste na estimação de modelos de dados em painel, utilizando uma amostra de seis bancos com relevância ao nível de investimento no mercado externo relativos ao período compreendido entre 2004 e 2014. Os resultados empíricos sugerem a existência de relações estatisticamente significativas entre as variáveis consideradas nos modelos. Foram encontrados indícios que associam consistentemente as variáveis emigração, Investimento Direto Estrangeiro, Produto Interno Bruto em Portugal e nos países de acolhimento, ativo bancário e inflação, com a evolução da atividade bancária no exterior. Adicionalmente, os resultados revelam que o desemprego e o rácio do crédito em relação ao ativo são estatisticamente significativos na sua influência sobre o indicador da rendibilidade dos bancos. Conclui-se que a significância dos fatores selecionados permite explicar o comportamento dos indicadores de negócio no exterior para os bancos estudados e, consequentemente, a validade do modelo de análise proposto. No entanto, não se exclui que outros elementos explicativos não ponderados no estudo tenham igualmente preponderância explicativa no processo de internacionalização do setor bancário.

Compensating variation and the young Portuguese emigrants: A study on how to keep our own

Emigration has been a very present word in Portugal. Due to the effects of the Economic Crisis and the Memorandum of Understanding policies, we have witnessed a significant yearly migration outflow of people searching for better conditions. This study aims to measure the factors affecting this flow as well as how much the probability of emigrating has evolved during the years bridging 2006 to 2012. I shall consider the decision of emigrating as Discrete Choice Random Utility maximization use a conditional Logit framework to model the probability choice for 31 OECD countries of destination. Moreover I will ascertain the compensating variation required such that the probability of choice in 2012 is adjusted back to 2007 values, keeping all other variables constant. I replicate this exercise using the unemployment rate instead of income. The most likely country of destination is Luxembourg throughout the years analyzed and the values obtained for the CV is of circa 1.700€ in terms of Income per capita and -11% in terms of the unemployment rate adjustment.

Abortion trends 1990-1999 in a Swiss region and determinants of abortion recurrence.

OBJECTIVE: To assess age- and nationality-specific trends in abortion rates over the last decade, and to describe women's characteristics, identifying risk factors for repeated abortion. METHODS: From 1990-1999, the Health Department of Canton Vaud (Switzerland) received 13'857 abortion requests from residents aged 14-49. Population data were obtained to compute rates. RESULTS: Both the number of abortions (1400 annually) as well as their rate (8.9 per thousand women [95% confidence interval (CI) 7.3-10.5]) were stable over the decade in question. The rate of abortion for foreign women, especially from ex-Yugoslavia and Africa, was twice that for Swiss women. Half of the requests came from single women, 43% had a low education level, and half were childless. The main reason for requesting termination of pregnancy was psychosocial (93%). The mean gestational age was 7.7 weeks (SD +/- 2.3), but 96% of requests were submitted before 12 weeks. Sixty-three percent of women reported that they had used no contraception, 36% the condom and 17% the pill. Among requests, the adjusted risk of repeated abortion (22% of abortion candidates) was greater among divorced/separated/widowed women (odds ratio [OR] 1.9 [95% CI 1.5-2.4]), unemployed women (OR 1.8 [95% CI 1.5-2.1]), and those who had not attended university (OR 1.6 [95% CI 1.1-2.2]). CONCLUSIONS: Although Swiss law only permitted abortion under strict conditions, this procedure was widely available in Vaud, which nevertheless has one of the lowest rates worldwide. Efforts must be intensified to ensure universal access to family planning services, especially for foreign women and adolescents. Professionals should also target "repeaters" to provide personalised counselling.

Genes mirror geography within Europe.

Understanding the genetic structure of human populations is of fundamental interest to medical, forensic and anthropological sciences. Advances in high-throughput genotyping technology have markedly improved our understanding of global patterns of human genetic variation and suggest the potential to use large samples to uncover variation among closely spaced populations. Here we characterize genetic variation in a sample of 3,000 European individuals genotyped at over half a million variable DNA sites in the human genome. Despite low average levels of genetic differentiation among Europeans, we find a close correspondence between genetic and geographic distances; indeed, a geographical map of Europe arises naturally as an efficient two-dimensional summary of genetic variation in Europeans. The results emphasize that when mapping the genetic basis of a disease phenotype, spurious associations can arise if genetic structure is not properly accounted for. In addition, the results are relevant to the prospects of genetic ancestry testing; an individual's DNA can be used to infer their geographic origin with surprising accuracy-often to within a few hundred kilometres.

Perception of the damaging effects of smoking, and brief cessation counselling by doctors.

An open prospective study was conducted among the patients visiting an urban medical policlinic for the first time without an appointment to assess whether the immigrants (who represent more than half of our patients) are aware of the health effects of smoking, whether the level of acculturation influences knowledge, and whether doctors give similar advice to Swiss and foreign smokers. 226 smokers, 105 Swiss (46.5%), and 121 foreign-born (53.5%), participated in the study. 32.2% (95% CI [24.4%; 41.1%]) of migrants and 9.6% [5.3%; 16.8%] of Swiss patients were not aware of negative effects of smoking. After adjustment for age, the multivariate model showed that the estimated odds of "ignorance of health effects of smoking" was higher for people lacking mastery of the local language compared with those mastering it (odds ratio (OR) = 7.5 [3.6; 15.8], p < 0.001), and higher for men (OR = 4.3 [1.9; 10.0], p < 0.001). Advice to stop smoking was given with similar frequency to immigrants (31.9% [24.2%; 40.8%] and Swiss patients (29.0% [21.0%; 38.5%]). Nonintegrated patients did not appear to receive less counselling than integrated patients (OR = 1.1 [0.6; 2.1], p = 0.812). We conclude that the level of knowledge among male immigrants not integrated or unable to speak the local language is lower than among integrated foreign-born and Swiss patients. Smoking cessation counselling by a doctor was only given to a minority of patients, but such counselling seemed irrespective of nationality.

Influence of socioeconomic factors on delays, management and outcome amongst patients with acute myocardial infarction undergoing primary percutaneous coronary intervention.

The outcome after primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI) is strongly affected by time delays. In this study, we sought to identify the impact of specific socioeconomic factors on time delays, subsequent STEMI management and outcomes in STEMI patients undergoing pPCI, who came from a well-defined region of the French part of Switzerland. A total of 402 consecutive patients undergoing pPCI for STEMI in a large tertiary hospital were retrospectively studied. Symptom-to-first-medical-contact time was analysed for the following socioeconomic factors: level of education, origin and marital status. Main exclusion criteria were: time delay beyond 12 hours, previous treatment with fibrinolytic agents or patients immediately referred for coronary artery bypass graft surgery. Therefore, 222 patients were finally included. At 1 year, there was no difference in mortality between the different socioeconomic groups. Furthermore, there was no difference in management characteristics between them. Symptom-to-first-medical-contact time was significantly longer for patients with a low level of education, Swiss citizens and unmarried patients, with median differences of 23 minutes, 18 minutes and 13 minutes, respectively (p <0.05). Nevertheless, no difference was found regarding in-hospital management and clinical outcome. This study demonstrates that symptom-to-first-medical-contact time is longer amongst people with a lower educational level, Swiss citizens and unmarried people. Because of the low mortality rate in general, these differences in delays did not affect clinical outcomes. Still, tertiary prevention measures should particularly focus on these vulnerable populations.

Global migration : patriarchy, propoganda and the well- being of women and children

This critical analysis explores the conflicted position of women as ''trailing spouses" and the effects on families who relocate globally under the auspices of a multinational corporation, by utilizing a discursive analysis of two contemporary films and available literature. Current portrayals of women and children in contemporary media provide emotional yet conflicting images of the perfect woman, wife, mother, child and family. The basic tenets of a North American patriarchal economic system are being televised around the world. Technological advancements have made it possible to advertise political agendas on a global television screen. Much of what we see is propaganda couched in films and advertisements that are designed to romantic~e the practice of deriving profits from the unpaid labor of woman and invisibility of children and child rearing. I intend to show that the materiality of trailing a spouse globally conflicts with these romanticized images and supports feminist literature that asserts the notion that mothers and children are oppressed and managed for the benefit of capital.

Locating home : the diverse experiences of recent newcomer youth and first generation youth within Ontario's education system

This study has found that youth who or whose parents had left their home country for fear-based reasons were less involved within their school and wider community than youth who left or whose parents left for reasons concerning their social mobility. Many existing studies focus on the challenges newcomer youth experience within the education system (see Anisef, Brown, Phythian, & Sweet, 2010), however through the use of qualitative methodologies this study expanded on the current literature by further examining why it is some youth are successful in overcoming such challenges, while others are not. This study supported what has been demonstrated in the literature regarding challenges faced by newcomer youth and resources to address such challenges. Despite challenges experienced within the education system, youth planned to complete secondary school and attend a postsecondary institution. However, not all youth anticipated remaining in Canada upon completion of their education, with youth or youth whose parents left their home country for fear-based reasons frequently discussing the possibility of returning to their or their parents' home country. Thus, perhaps these youth were less involved within their school, as their goal was not necessarily to establish or maintain connections within their community as they may have viewed residing in Canada as temporary. This finding has important implications, as there are benefits to involvement in extracurricular activities, which may assist youth in overcoming challenges encountered within the education system. Therefore, it would seem that youth who had or whose parents had left their home country for reasons concerning their social mobility may have be at an advantage within the education system with respect to their involvement in school. Perhaps then this differential involvement may at least partially explain why it is some newcomer youth are able to overcome challenges they experience in the education system, while others are not. Both policy and theoretical implications are discussed.
