Wage differentials between native and immigrant women in Spain: accounting for differences in support

Purpose: The objective of the study is to quantify the wage gap between native and immigrant women in Spain, taking into account differences in their characteristics and the need to control for common support. If immigrant women are segregated in occupations with few native women, it is important to take this into account to analyse wage differentials between both collectives. Methodology: We use microdata from the Continuous Sample of Working Histories (Muestra Continua de Vidas Laborales) on wages and other personal characteristics such as gender, country of origin, and age to apply the matching procedure and the decomposition of the wage gap along the lines of Ñopo (2008) for the analysis of wage differentials between native and immigrant women. The advantage of this procedure is that we can simultaneously estimate the common support and the mean counterfactual wage for the women on the common support (i.e., comparing native and immigrant women with similar observable characteristics). In addition, we can describe differences not only at the mean but also along the entire wage distribution. Findings: The results obtained indicate that, on average, immigrant women earn less than native women in the Spanish labour market. This wage gap is bigger when we consider immigrant women from developing countries, but our main finding is that an important part of this wage gap is related to differences in common support (i.e., immigrant women are segregated in certain jobs with low wages different from those occupied by native women). If the need to control for common support is neglected, estimates of the wage gap will be biased. Originality: Studying the case of Spain is particularly interesting because it is a country with abundant and recent immigration. Immigrant women account for more than half of the total immigrants in Spain, and unlike other host countries, they come from a highly varied range of countries, with origins as diverse as Latin America, the Maghreb and Eastern Europe. To our knowledge, no other study has explicitly focused on the analysis of the wage differential of immigrant women in the Spanish labour market by taking into account the need to control for common support. Moreover, published papers illustrating the potentiality of Ñopo"s (2008) methodology are also very scarce.

Caracterização de plantas e de frutos de araticunzeiro (Annona crassiflora Mart.) nativos no Cerrado Matogrossense

O araticunzeiro (Annona crassiflora Mart - Annonaceae) é uma frutífera nativa do cerrado brasileiro que necessita de estudos visando à geração de dados para subsidiar pesquisas relativas à sua domesticação. Com o presente trabalho, objetivou-se estudar uma população de araticunzeiro em relação ao diâmetro do caule e altura das plantas, à produção e às características físicas e químicas de frutos. Nas plantas, mensuraram-se diâmetro do caule, altura e produção de frutos. Nos frutos, analisaram-se os diâmetros longitudinal (DL) e transversal (DT), a relação DL/DT, as massas do fruto, da casca, da semente e da polpa, e calculou-se o rendimento de polpa. Na polpa, efetuaram-se as determinações de sólidos solúveis (SS), acidez titulável (AT), relação SS/AT, pH e umidade. As árvores possuem diâmetro do caule de 10,4±3,1 cm e altura de 3,7±0,7m com produção média de 6,0±3,6 frutos por planta. Em média, os frutos possuem DL de 14,2±1,4, DT de 15,2±2,2 e relação DL/DT de 0,9±0,1; possuem massa média de 1.565,5±508,5g, tendo as massas da casca, das sementes e da polpa médias de 662,2±198,2g, 179,8±66,2g e 723,5±276,7g, respectivamente, com rendimento médio de polpa igual a 45,9±4,7% do fruto. Na polpa, constataram-se médias de SS de 17,60±1,86 ºBrix, AT de 0,37±0,11% de ácido málico, relação SS/AT de 52,23±17,64, pH de 4,45±0,23 e umidade média igual a 74,3±2,86%. O araticunzeiro possui características físicas e químicas que o tornam uma alternativa para a fruticultura nativa brasileira.

Polinização e biologia reprodutiva de Araticum-liso (Annona coriacea Mart.: Annonaceae) em uma área de cerrado paulista: implicações para fruticultura

Anonáceas, em geral, são espécies cantarófilas e altamente especializadas, apresentando pétalas espessas, carnosas e nutritivas que formam uma câmara floral com ocorrência de termogênege. Este estudo objetivou verificar os efetivos polinizadores e sistema reprodutivo prevalente em A. coriacea. Flores foram marcadas e acompanhadas durante períodos do dia e da noite para verificar os polinizadores legítimos. Tratamentos de polinização manual foram realizados para determinar o sistema reprodutivo. Besouros escarabeídeos Cyclocephala atricapilla e Cyclocephala quatuordecimpunctata (Dynastinae) foram atraídos pelo odor emitido pelas flores no início da noite já contendo pólen em seus corpos e penetraram na câmara floral, onde permaneceram por até 48h alimentando-se das pétalas e de pólen, copulando, e ao tocarem nos estigmas receptivos, depositaram pólen. Posteriormente, flores em fase masculina liberaram pólen que novamente sujou o corpo dos besouros e, com a queda da flor, voaram para outra flor recém-aberta e em fase feminina, iniciando novo ciclo de polinização. A. coriacea é uma espécie autocompatível e Cyclocephala foram polinizadores muito eficientes.

Fruit and vegetables and cancer risk : a review of southern European studies

High intakes of fruit and vegetables may reduce the risk of cancer at several sites. Evidence has been derived mainly from case-control studies. We reviewed the relationship between consumption of vegetables and fruit and the risk of several common cancers in a network of Italian and Swiss case-control studies including over 10 000 cases of fourteen different cancers and about 17 000 controls. Data were suggestive of a protective role of vegetable intake on the risk of several common epithelial cancers. OR for the highest compared with the lowest levels of consumption ranged from 0·2 (larynx, oral cavity and pharynx) to 0·9 (prostate). Inverse associations were found for both raw and cooked vegetables, although for upper digestive tract cancers the former were somewhat stronger. Similar inverse associations were found for cruciferous vegetables. Frequent consumption of allium vegetables was also associated with reduced risk of several cancers. Fruit was a favourable correlate of the risk of several cancers, particularly of the upper digestive tract, with associations generally weaker than those reported for vegetables. A reduced risk of cancers of the digestive tract and larynx was found for high consumption of citrus fruit. Suggestive protections against several forms of cancer, mainly digestive tract cancers, were found for high consumption of apples and tomatoes. High intakes of fibres, flavonoids and proanthocyanidins were inversely related to various forms of cancer. In conclusion, data from our series of case-control studies suggested a favourable role of high intakes of fruit and vegetables in the risk of many common cancers, particularly of the digestive tract. This adds evidence to the indication that aspects of the Mediterranean diet may have a favourable impact not only on CVD, but also on several common (epithelial) cancers, particularly of the digestive tract.

INFLUENCE OF INFORMATION ABOUT THE BENEFITS OF CONSUMING FRUIT ON CONSUMER PREFERENCES IN TEMUCO, REGION OF THE ARAUCANÍA

ABSTRACT With the aim of identifying strategies to increase fruit consumption in Temuco, consumer segments were classified according to the importance and preference of theattributes type of fruit, package/ brand, benefit associated with fruit consumption and price. A survey was applied to 400 people in Temuco,Chile, distributed using a simple allocation: 200 working adults and 200university students. The questionnaire included the SWFL (Satisfaction with Food-related Life) scale, respondents’ fruit consumption habits and their characteristics. Using conjoint and cluster analyses, three segments were distinguished: Group 1 (22.0%) gave greatest importance to the package/brand and preferred themessage “prevents diseases” and “without information”; Group 2 (47.5%) gave greatest importance to the package/brand and preferred the message “prevents diseases”; Group 3 (30.5%) assigned greatest importance to the price and preferred the message “contains antioxidants”. The segments differed in their level of satisfaction with food-related life, self-declared lifestyle, age and presence of university students. The results provide input to promote fruit consumption in working adults and university students.

THE ROLE OF MINERAL NUTRITION ON YIELDS AND FRUIT QUALITY IN GRAPEVINE, PEAR AND APPLE

ABSTRACT Fertilization of temperate fruit trees, such as grapevine ( Vitis spp.), apple ( Malus domestica), and pear ( Pyrus communis) is an important tool to achive maximum yield and fruit quality. Fertilizers are provided when soil fertility does not allow trees to express their genetic potential, and time and rate of application should be scheduled to promote fruit quality. Grapevine berries, must and wine quality are affected principally by N, that regulate the synthesis of some important compounds, such as anthocyanins, which are responsible for coloring of the must and the wine. Fermenation of the must may stop in grapes with low concentration of N because N is requested in high amount by yeasts. An N excess may increase the pulp to peel ratio, diluting the concentration of anthocyanins and promoting the migration of anthocyanins from berries to the growing plant organs; a decrease of grape juice soluble solid concentration is also expected because of an increase in vegetative growth. Potassium is also important for wine quality contributing to adequate berry maturation, concentration of sugars, synthesis of phenols and the regulation of pH and acidity. In apple and pear, Ca and K are important for fruit quality and storage. Potassium is the most important component of fruit, however, any excess should be avoided and an adequate K:Ca balance should be achieved. Adequate concentration of Ca in the fruit prevents pre- and post-harvest fruit disorders and, at the same time, increases tolerance to pathogens. Although N promotes adequate growth soil N availability should be monitored to avoid excessive N uptake that may decrease fruit skin color and storability.

Associations between fruit and vegetable consumption and psychological distress: results from a population-based study.

BACKGROUND: Several studies observed associations of various aspects of diet with mental health, but little is known about the relationship between following the 5-a-day recommendation for fruit and vegetables consumption and mental health. Thus, we examined the associations of the Swiss daily recommended fruit and vegetable intake with psychological distress. METHODS: Data from 20,220 individuals aged 15+ years from the 2012 Swiss Health Survey were analyzed. The recommended portions of fruit and vegetables per day were defined as 5-a-day (at least 2 portions of fruit and 3 of vegetables). The outcome was perceived psychological distress over the previous 4 weeks (measured by the 5-item mental health index [MHI-5]). High distress (MHI-5 score ≤ 52), moderate distress (MHI-5 > 52 and ≤ 72) and low distress (MHI-5 > 72 and ≤ 100) were differentiated and multinomial logistic regression analyses adjusted for known confounding factors were performed. RESULTS: The 5-a-day recommendation was met by 11.6 % of the participants with low distress, 9.3 % of those with moderate distress, and 6.2 % of those with high distress. Consumers fulfilling the 5-a-day recommendation had lower odds of being highly or moderately distressed than individuals consuming less fruit and vegetables (moderate vs. low distress: OR = 0.82, 95 % confidence interval [CI] 0.69-0.97; high vs. low distress: OR = 0.55, 95 % CI 0.41-0.75). CONCLUSIONS: Daily intake of 5 servings of fruit and vegetable was associated with lower psychological distress. Longitudinal studies are needed to further determine the causal nature of this relationship.

Reconstructing native American migrations from whole-genome and whole-exome data.

There is great scientific and popular interest in understanding the genetic history of populations in the Americas. We wish to understand when different regions of the continent were inhabited, where settlers came from, and how current inhabitants relate genetically to earlier populations. Recent studies unraveled parts of the genetic history of the continent using genotyping arrays and uniparental markers. The 1000 Genomes Project provides a unique opportunity for improving our understanding of population genetic history by providing over a hundred sequenced low coverage genomes and exomes from Colombian (CLM), Mexican-American (MXL), and Puerto Rican (PUR) populations. Here, we explore the genomic contributions of African, European, and especially Native American ancestry to these populations. Estimated Native American ancestry is 48% in MXL, 25% in CLM, and 13% in PUR. Native American ancestry in PUR is most closely related to populations surrounding the Orinoco River basin, confirming the Southern American ancestry of the Taíno people of the Caribbean. We present new methods to estimate the allele frequencies in the Native American fraction of the populations, and model their distribution using a demographic model for three ancestral Native American populations. These ancestral populations likely split in close succession: the most likely scenario, based on a peopling of the Americas 16 thousand years ago (kya), supports that the MXL Ancestors split 12.2kya, with a subsequent split of the ancestors to CLM and PUR 11.7kya. The model also features effective populations of 62,000 in Mexico, 8,700 in Colombia, and 1,900 in Puerto Rico. Modeling Identity-by-descent (IBD) and ancestry tract length, we show that post-contact populations also differ markedly in their effective sizes and migration patterns, with Puerto Rico showing the smallest effective size and the earlier migration from Europe. Finally, we compare IBD and ancestry assignments to find evidence for relatedness among European founders to the three populations.

First records and potential palaeoecological significance of Dianella (Xanthorrhoeaceae), an extinct representative of the native flora of Rapa Nui (Easter Island).

Easter Island, a remote island in the Pacific Ocean, is currently primarily covered by grasslands, but palaeoecological studies have shown the former presence of different vegetation. Much of its original biota has been removed during the last two millennia, most likely by human activities, and little is known about the native flora.Macrofossil and pollen analyses of a sediment core from the Raraku crater lake have revealed the occurrence of a plant that is currently extinct from the island: Dianella cf. intermedia/adenanthera (Xanthorrhoeaceae), which grew and disappeared at the Raraku site long before human arrival. The occurrence of Dianella within the Raraku sedimentary sequence (between 9.4 and 5.4 cal. kyr B.P.) could have been linked to the existence of favorable palaeoenvironmental conditions (peatland rather than the present-day lacustrine environment) during the early to mid Holocene. This finding contributes new knowledge about indigenous plant diversity on Easter Island and reinforces the usefulness of further macrofossil and pollen analyses to identify native species on Easter Island and elsewhere.

Drenaje torácico cerrado. Procedimiento y cuidados de enfermería a propósito de un caso

La acumulación en el espacio pleural de aire y/o sangre, pus o partículas grasas, o la acumulación de líquido por tumores que infiltran la pleura, impide la libre expansión pulmonar, pudiendo llegarse al colapso de este pulmón con un intercambio gaseoso limitado o nulo. Por esto, sea cual sea la causa (traumatismos, enfermedades, cirugías), hemos de extraer estas sustancias de la cavidad pleural. Podemos hacerlo a través de una toracocentesis evacuadora, pero en muchos casos la cantidad y las características de las sustancias o el estado del paciente recomiendan instaurar un drenaje torácico permanente y conectarlo a un dispositivo cerrado de recogida. Esto se consigue introduciendo un tubo o trocar a través de la pared torácica hasta el espacio pleural, vaciando las sustancias alojadas de forma patológica. Este tubo, o trocar, se conecta a un aspirador con la finalidad de mantener la presión negativa fisiológica de la cavidad pleural y facilitar de esta manera la completa expansión de los pulmones. Hay trocares de diversas dimensiones y diferentes modelos de dispositivo de recogida, pero todos se basan, a partir de 1876, en el sistema que utilizó Gotthard Bülau para el tratamiento de los empiemas. Tanto para la preparación del paciente como del material, para la instauración y los cuidados, desde el primer momento hasta la retirada, pasando por las muchas valoraciones, comprobaciones y atenciones para evitar los riesgos y las complicaciones inherentes a este drenaje, es imprescindible que los profesionales de enfermería conozcan el procedimiento y las muchas particularidades que hay que observar con él, dada la especificidad de la cavidad en la que está inserto. Asimismo, es fundamental el conocimiento del dispositivo de recogida cerrado más utilizado (Pleur-evac®) desde la preparación, pasando por el funcionamiento y hasta los controles necesarios para una utilización correcta. Este artículo pretende unificar criterios de actuación en los cuidados que requieren los pacientes portadores de drenaje torácico.

Drenaje torácico cerrado. Sistema de recogida no reutilizable: Pleur-evac®

Funcionamiento del sistema desechable de recogida Pleur-evac®. Se trata de un sistema compacto de recogida de drenaje con sello de agua de manejo fácil construido sobre la base del sistema convencional de montaje de drenaje de aspiración de tres botellas. Este sistema se basa en el utilizado en 1876 por Gotthard Bülau para el tratamiento de empiemas y que ha dado nombre a los sistemas de recogida...

Job loss among immigrant and native workers: evidence from Spain's economic downturn

The profound crisis that has affected the Spanish economy since mid - 2008 has been characterized by significant job losses and a marked rise in the country´s unemployment rate. However, unemployment has had a differential impact on different population groups. Compared to native, immigrant workers have experienced higher rates of job loss. Against this backdrop, this paper examines the differences between immigrants and natives (distinguished by gender) in terms of their probability of suffering job loss in the downturn of late 2008 and 2009. Our results indicate that the higher rate of job loss among female immigrant workers can be fully explained by their lower endowment of human capital. By contrast, human capital endowment and over-representation in certain occupations, sectors and regions in which the crisis had greatest impact do not appear to be the only reason for the penalty suffered by immigrant males in terms of their chances of losing their job in the downturn.
