Ofshoring de servicios en la economía española en el periodo 2000-2007

La literatura económica ha centrado la atención en el offshoring de servicios y en su efecto sobre el nivel de empleo nacional, unido a importantes críticas en relación al impacto negativo que esta estrategia provoca en términos de destrucción de empleos nacionales. En este trabajo se analiza la relevancia que tiene el offshoring de servicios en la economía española y, en concreto, en las ramas de servicios y se estudia su efecto sobre el nivel de empleo de este sector. El análisis empírico se lleva a cabo estimando una función de demanda de trabajo con elasticidad de sustitución constante (CES), incluyendo en la misma el efecto de offshoring. Este estudio se realiza para el periodo previo a la crisis, 2000-2007, a partir de los datos contenidos en las Tablas Input-Output de la Contabilidad Nacional del INE.

No effect of unemployment on intimate partner-related femicide during the financial crisis: a longitudinal ecological study in Spain

Background: Spain’s financial crisis has been characterized by an increase in unemployment. This increase could have produced an increase in deaths of women due to intimate partner-related femicides (IPF). This study aims to determine whether the increase in unemployment among both sexes in different regions in Spain is related to an increase in the rates of IPF during the current financial crisis period. Methods: An ecological longitudinal study was carried out in Spain’s 17 regions. Two study periods were defined: pre-crisis period (2005–2007) and crisis period (2008–2013). IPF rates adjusted by age and unemployment rates for men and women were calculated. We fitted multilevel linear regression models in which observations at level 1 were nested within regions according to a repeated measurements design. Results: Rates of unemployment have progressively increased in Spain, rising above 20 % from 2008 to 2013 in some regions. IPF rates decreased in some regions during crisis period with respect to pre-crisis period. The multilevel analysis does not support the existence of a significant relationship between the increase in unemployment in men and women and the decrease in IPF since 2008. Discussion: The increase in unemployment in men and women in Spain does not appear to have an effect on IPF. The results of the multilevel analysis discard the hypothesis that the increase in the rates of unemployment in women and men are related to an increase in IPF rates. Conclusions: The decline in IPF since 2008 might be interpreted as the result of exposure to other factors such as the lower frequency of divorces in recent years or the medium term effects of the integral protection measures of the law on gender violence that began in 2005.

Aceptabilidad de la vacuna contra el VPH en estudiantes universitarios españoles durante la etapa pre-vacunal: un estudio transversal

Introducción. El cáncer de cuello de útero (CCU), segunda causa de mortalidad por cáncer en mujeres, está asociado a la infección por virus de papiloma humano (VPH), cuya máxima prevalencia se sitúa entre los 20 y 24 años de edad. Desde 2006 se dispone de una vacuna contra el VPH. El objetivo de este estudio es evaluar los conocimientos sobre CCU, la infección por VPH y su vacuna, valorando su aceptabilidad en población universitaria. Métodos. Estudio transversal sobre 1.750 estudiantes de la Universidad de Alicante (2008) seleccionados al azar, proporcional por sexo y estudios, mediante un cuestionario ad-hoc validado. Se calcularon porcentajes, intervalos de confianza, tablas de contingencia según sexo, edad y tipo de estudios, calculando odds ratios ajustadas (OR). Resultados. Muestra con 58,6% mujeres y 6,6% de estudiantes biosanitarios. Un 87,3% dispuestos a vacunarse frente al VPH, el 94,3% vacunaría a sus hijas, un 48,0% había oído hablar de la vacuna. El 90,6% tiene bajos conocimiento sobre la infección por VPH y un 82,2% sobre la vacuna. Un 22,4% manifiesta conocer la asociación entre VPH y CCU. Las mujeres registran OR mayores en conocimientos y predisposición a vacunarse. La aceptabilidad de la vacuna contra VPH se asocia con el sexo y la confianza en las vacunas como método preventivo, la influencia de los conocimientos previos es escasa sobre la predisposición vacunal. Conclusiones. Alta aceptabilidad de la vacuna en el periodo estudiado. Aumentar la confianza hacia las vacunas puede influir en una mejor predisposición a vacunarse.

A VLT/FLAMES survey for massive binaries in Westerlund 1. IV. Wd1-5 – binary product and a pre-supernova companion for the magnetar CXOU J1647-45?

Context. The first soft gamma-ray repeater was discovered over three decades ago, and was subsequently identified as a magnetar, a class of highly magnetised neutron star. It has been hypothesised that these stars power some of the brightest supernovae known, and that they may form the central engines of some long duration gamma-ray bursts. However there is currently no consenus on the formation channel(s) of these objects. Aims. The presence of a magnetar in the starburst cluster Westerlund 1 implies a progenitor with a mass ≥40 M⊙, which favours its formation in a binary that was disrupted at supernova. To test this hypothesis we conducted a search for the putative pre-SN companion. Methods. This was accomplished via a radial velocity survey to identify high-velocity runaways, with subsequent non-LTE model atmosphere analysis of the resultant candidate, Wd1-5. Results. Wd1-5 closely resembles the primaries in the short-period binaries, Wd1-13 and 44, suggesting a similar evolutionary history, although it currently appears single. It is overluminous for its spectroscopic mass and we find evidence of He- and N-enrichement, O-depletion, and critically C-enrichment, a combination of properties that is difficult to explain under single star evolutionary paradigms. We infer a pre-SN history for Wd1-5 which supposes an initial close binary comprising two stars of comparable (~ 41 M⊙ + 35 M⊙) masses. Efficient mass transfer from the initially more massive component leads to the mass-gainer evolving more rapidly, initiating luminous blue variable/common envelope evolution. Reverse, wind-driven mass transfer during its subsequent WC Wolf-Rayet phase leads to the carbon pollution of Wd1-5, before a type Ibc supernova disrupts the binary system. Under the assumption of a physical association between Wd1-5 and J1647-45, the secondary is identified as the magnetar progenitor; its common envelope evolutionary phase prevents spin-down of its core prior to SN and the seed magnetic field for the magnetar forms either in this phase or during the earlier episode of mass transfer in which it was spun-up. Conclusions. Our results suggest that binarity is a key ingredient in the formation of at least a subset of magnetars by preventing spin-down via core-coupling and potentially generating a seed magnetic field. The apparent formation of a magnetar in a Type Ibc supernova is consistent with recent suggestions that superluminous Type Ibc supernovae are powered by the rapid spin-down of these objects.

Anglicisms and calques in upper social class in pre-revolutionary Cuba (1930–1959): A sociolinguistic analysis

The geographical proximity and socioeconomic dependence on the United States brought about a deep rooted anglicization of the Cuban Spanish lexis and social strata, especially throughout the Neocolonial period (1902–1959). This study is based on the revision of a renowned newspaper of that time, Diario de la Marina, and the corresponding elaboration of a corpus of English-induced loanwords. Diario de la Marina particularly targeted upper social class, and only crónicas sociales (society pages’ columns) and print advertising were revised because of their fully descriptive texts, which encoded the ruling class ideology and consumerism. The findings show that there existed a high number of lexical and cultural anglicisms in the sociolect in question, and that the sociolinguistic anglicization was openly embraced by the upper socioeconomic stratum, entailing a differentiating sign of sophistication and social stratification. Likewise, a number of the anglicisms collected, particularly those related with social events, are unused in contemporary Cuban Spanish, which suggests a major semantic shifting in this sociolect after 1959.
