Análisis de la desigualdad económica en los municipios del País Vasco agrupados por tamaño de la población. Economic Inequality in the municipalities of the Basque Country aggregated by population size.

This paper analyses the economic inequality in the municipalities of the Basque Country during the period 1996 and 2010. We have used dates from the Udalmap database mainly the GDP per capita. We have drawn Lorenz Curves and also we have computed Gini indexes to analyse the evolution of inequality during this period. Therefore, we have concluded that there has been an increase of the economic inequality in the municipalities of the Basque Country during this period of time.

Nivel de vida de los pensionistas en España

[ES] La situación socioeconómica actual ha provocado la traslación de una mayor responsabilidad a la población para organizar su ahorro a largo plazo. La planificación financiera será la hoja de ruta de los ciudadanos para, a lo largo de su ciclo vital, destinar los ahorros necesarios para su jubilación. Sin embargo, la planificación no termina una vez alcanzada dicha edad, sino que los ahorros deben seguir gestionándose de forma que garanticen la cobertura de las necesidades de los jubilados hasta su fallecimiento. La elevada tasa de paro, el aumento de la longevidad y el envejecimiento de la población son factores que afectan a las arcas públicas de la Seguridad Social. Por lo tanto, ¿tienen los actuales pensionistas la garantía de recibir una pensión de jubilación que les permita vivir dignamente? Para dar respuesta a esta pregunta, será de vital importancia conocer la acumulación de capital durante su vida de activo para así, combinando la fuente de ingresos públicos, sus gastos y sus ahorros privados, conocer cuál será su nivel de vida durante su etapa como jubilados. Por lo tanto, a lo largo de este informe trataremos de identificar cuáles son los diferentes productos de ahorro en los que ha venido invirtiendo la población española previo a la jubilación, en función de su edad y renta. Para ello analizaremos la Encuesta Financiera de las Familias del año 2011. Con todo este estudio, pretendemos obtener resultados para determinar el nivel de ingresos y gastos de los pensionistas.

Dobutamine in Paediatric Population: A Systematic Review in Juvenile Animal Models

Objective: Although dobutamine is widely used in neonatal clinical practice, the evidence for its use in this specific population is not clear. We conducted a systematic review of the use of dobutamine in juvenile animals to determine whether the evidence from juvenile animal experiments with dobutamine supported the design of clinical trials in neonatal/ paediatric population. Methods: Studies were identified by searching MEDLINE (1946-2012) and EMBASE (1974-2012). Articles retrieved were independently reviewed by three authors and only those concerning efficacy and safety of the drug in juvenile animals were included. Only original articles published in English and Spanish were included. Results: Following our literature search, 265 articles were retrieved and 24 studies were included in the review: 17 focused on neonatal models and 7 on young animal models. Although the aims and design of these studies, as well as the doses and ages analysed, were quite heterogeneous, the majority of authors agree that dobutamine infusion improves cardiac output in a dose dependent manner. Moreover, the cardiovascular effects of dobutamine are influenced by postnatal age, as well as by the dose used and the duration of the therapy. There is inadequate information about the effects of dobutamine on cerebral perfusion to draw conclusions. Conclusion: There is enough preclinical evidence to ensure that dobutamine improves cardiac output, however to better understand its effects in peripheral organs, such as the brain, more specific and well designed studies are required to provide additional data to support the design of clinical trials in a paediatric population.

Envelhecimento, ciclo de vida e mudanças socioeconômicas: novos desafios para os sistemas de seguridade social

O processo de envelhecimento populacional, ainda que amplamente reconhecido como uma das principais conquistas do século XX engendra o desafio de assegurar que o processo de desenvolvimento ocorra com base em princípios capazes de garantir a dignidade humana e a equidade entre os grupos etários na partilha dos recursos, direitos e responsabilidades sociais. Além dos desafios impostos aos já tradicionais programas constantes dos atuais sistemas de seguridade social, o envelhecimento populacional acrescenta uma nova questão ou risco social: os cuidados de longa duração, demandados pelos idosos com perda de capacidade instrumental e/ou funcional para lidar com as atividades do cotidiano. Por capacidade instrumental pode-se entender a capacidade para a realização de atividades relacionadas a, por exemplo: preparar refeições, fazer compras no mercado, ir ao banco, cuidar da casa etc. Capacidade funcional, por sua vez, refere-se às seguintes atividades: alimentar-se, banhar-se, caminhar distâncias curtas, vestir-se etc. A preocupação com os cuidados de longa duração dos idosos nos países desenvolvidos, onde o processo de envelhecimento populacional já se encontra mais avançado, surgiu como uma necessidade de se separar os custos crescentes com o tratamento dos idosos dos demais gastos com saúde. Os custos, tangíveis ou não, envolvidos na atividade de cuidar/assistir aos idosos tendem a aumentar em função da entrada maciça das mulheres no mercado de trabalho e das mudanças nos contratos de gênero, sugerindo crescentes dificuldades para que as famílias arquem com a responsabilidade pelo cuidado de seus idosos. Em países em desenvolvimento, como o Brasil, essa questão é agravada por se somar a uma ampla lista a ser respondida pelos sistemas de seguridade social, tais como a pobreza, a exclusão de crescentes contingentes da população e o nível de desigualdade vigente. No Brasil, para que se possa avançar no debate sobre os cuidados de longa duração voltados para uma população idosa crescente, faz-se necessário rediscutir e redefinir uma série de parâmetros do atual sistema de seguridade social, em especial, a expressiva parcela de trabalhadores informais alijados do mesmo. O precário equilíbrio, ou resultado, do sistema de seguridade social brasileiro precisa ser revisto e analisado a luz das tendências demográficas, sociais e econômicas que se vislumbram para os próximos 20 ou 30 anos. Somente após o reequacionamento do sistema é possível pensar a incorporação desta nova e latente demanda da sociedade brasileira.

A report on the population structure of adult salmon and sea trout in the River Lune using scale samples - with reference to historical data.

During 1993, a comprehensive data set of scale readings, length and weight measurements was established for migratory salmonids on the River Lune. This information was collected using three methods of fish capture: 1. The Lune estuary commercial nets. 2. River Lune Forge weir fish trap. 3. River Lune rod catch scale returns. Additional information was contributed by the Kent, Leven and Duddon rod and commercial fisheries. The data shows that the salmon stock in 1993 was dominated by two year old smolts. This varies from year to year. The sea trout population displays a normal population curve in terms of numbers of fish in each age and weight class. The growth rate of salmon and sea trout is very similar even though salmon have the benefit of high sea feeding.

Sarcopenia em pacientes idosos com doença renal crônica em hemodiálise

Os pacientes idosos em hemodiálise (HD) são altamente suscetíveis ao desenvolvimento de sarcopenia, devido ao processo natural de envelhecimento e ao catabolismo induzido pelo procedimento de HD. O objetivo deste estudo foi primeiro, avaliar a prevalência de sarcopenia, dinapenia e atrofia muscular em um grupo de pacientes idosos em HD; o segundo, avaliar se os critérios aplicados para o diagnóstico de sarcopenia, propostos por sociedades internacionais, são capazes de distinguir os pacientes com pior condição clínica, estado nutricional e qualidade de vida. Este estudo multicêntrico e transversal incluiu 94 pacientes idosos em HD (> 60 anos) de cinco centros de diálise. Todos os participantes foram submetidos à avaliação antropométrica, de composição corporal, força de preensão manual (FPM), laboratorial e avaliação da condição nutricional através da avaliação subjetiva global de 7 pontos (AGS-7p). Adicionalmente, os participantes responderam um questionário de qualidade de vida. Para o diagnóstico de sarcopenia, foram adotados os critérios propostos por sociedades internacionais, que englobam os parâmetros indicativos de baixa massa muscular e baixa função muscular. Para a massa muscular adotou-se o índice de massa magra (IMM) < percentil 20 para o gênero e faixa etária de uma população de referência, avaliado a partir da massa magra obtida pelo somatório de dobras cutâneas. Para o critério de baixa função muscular, adotou-se a FPM < percentil 10 para o gênero, faixa etária e o braço utilizado de uma população de referência. Os pacientes foram classificados como Sarcopênicos (baixo IMM associado à baixa FPM); Dinapênicos (baixa FPM) e Atrofia muscular (baixo IMM). A sarcopenia estava presente em 13.8% dos pacientes, enquanto a dinapenia foi observada em 37.2% e a atrofia muscular em 35.1%. A sarcopenia foi capaz de distinguir os pacientes que possuíam maior comprometimento do estado nutricional e da composição corporal. O critério de função muscular (isoladamente ou em combinação com a massa muscular) também identificou os pacientes com pior qualidade de vida. Em conclusão, a prevalência de sarcopenia foi observada em 13,8% do grupo. Entretanto, ao usar apenas critérios que indicam redução da força ou massa muscular, esta prevalência aumentou para 30%. A condição de sarcopenia distinguiu pacientes com pior estado nutricional e qualidade de vida.

The Spanish Pension System: Overview and Long-Term Projections

In the middle of the so-called pension crisis, the ageing of population and the sharp decrease in affiliations to Social Security are threatening the well-functioning of the Spanish public pension system. The purpose of this paper is to present the main challenges to be faced by the Spanish pension system, as well as to shed light on the main determinants that will condition the evolution of pension expenditure over GDP along the following decades. This quantitative analysis, which considers the 2011 and 2013 pension reforms, uses the latest data on the Spanish demographic, labor market and institutional factors in order to project the evolution of the system from the expenditure side up to 2060. For the purpose of analyzing the dynamics and the underlying drivers of pension expenditure, the so-called aggregate accounting approach will be utilized. The alternative scenarios proposed allow for exploring the robustness of the results within the baseline scenario, which constitutes the reference point of projections in the exercise. The analysis concludes that, by the end of the projected period, Spain will count on a similar public pension expenditure ratio as the current one.

Report on the analysis of salmon scale samples returned by anglers on the Rivers Ribble and Hodder

Fisheries technical staff from the North West Central Area of the National Rivers Authority (NRA) currently provide a service for the ageing of salmon scales from fish caught by anglers on the Rivers Ribble and Hodder in order to gather information on the biological characteristics of the salmon population on the River Ribble system in terms of weight, freshwater age and sea age. At the beginning of each fishing season, scale envelopes are distributed by the NRA to angling clubs and some individual anglers. Scales taken from salmon caught on the rivers are returned to the NRA Central Area Office by the anglers, or more often, by NRA bailiffs. The age of each fish caught is then determined by the identification and counting of annuli for both the river and sea zones on the scale. Information is provided by the angler on the scale packet concerning the length and weight of the fish caught, and the date, location and method of capture. Both this information and the age of the fish is recorded on a database. These data can be used to investigate the distribution, and exploitation patterns of the different age classes of the salmon stock within the river system. This report is principally concerned with the scale samples received in 1994, although comparison is also made with samples from 1993 and 1992. References to data will all relate to that received in 1994 unless an alternate year is stated.

Aspects of the biology and population dynamics of freshwater mussels in Lake Kariba and Lake McIlwaine

The essential aim of this study was to provide a broad foundation of biological knowledge upon which a programme of mussel utilization and management could be built. Results of the study are presented in three main sections. Part 1 describes the stock of Lake Kariba and Lake McIlwaine; part 2 describes various aspects of the breeding biology of the three species; and part 3 presents the results of morphological, biochemical and age analyses - aspects which are used for initial standing crop and production calculations. The final discussion concludes the thesis with a general examination in ecological terms of the factors which have influenced the development and nature of the mussel faunas of the two lakes under consideration.

Effects of the 1997-1998 El Niño on population size and diet of the Galápagos sea lion (Zalophus wollebaeki)

The multi-annual climatic event, El Niño Southern Oscillation (ENSO) is an important factor in the population dynamics of coastal marine species in the Galápagos. The Galápagos sea lion, Zalophus wollebaeki, suffered an apparent population decline of about 50%, considering both mortality and movements away from study sites during the 1997-98 El Niño. This change was in part due to changes in the availability of sardines of the Family Clupeidae, its main prey. These declines resulted partly from elevated mortality (35%) in sea lion colonies, particularly among pups, juveniles (< 1 year old), and dominant males and as a result of movements of adults elsewhere (15%), presumably where there were alternative prey and better environmental conditions.

Population structure of pink salmon (Oncorhynchus gorbuscha) in British Columbia and Washington, determined with microsatellites

Population structure of pink salmon (Oncorhynchus gorbuscha) from British Columbia and Washington was examined with a survey of microsatellite variation to describe the distribution of genetic variation. Variation at 16 microsatellite loci was surveyed for approximately 46,500 pink salmon sampled from 146 locations in the odd-year broodline and from 116 locations in the even-year broodline. An index of genetic differentiation, FST, over all populations and loci in the odd-year broodline was 0.005, with individual locus values ranging from 0.002 to 0.025. Population differentiation was less in the even-year broodline, with a FST value of 0.002 over all loci, and with individual locus values ranging from 0.001 to 0.005. Greater genetic diversity was observed in the odd-year broodline. Differentiation in pink salmon allele frequencies between broodlines was approximately 5.5 times greater than regional differentiation within broodlines. A regional structuring of populations was the general pattern observed, and a greater regional structure in the odd-year broodline than in the even-year broodline. The geographic distribution of microsatellite variation in populations of pink salmon likely ref lects a distribution of broodlines from separate refuges after the last glaciation period.
