Inequality in analgesic prescription in Spain: a gender development issue

Objectives: It is well known that sex differences in analgesic prescription are not merely the logical result of greater prevalence of pain in women, since this therapeutic variability is related to factors such as educational level or social class. This study aims to analyse the relationship between analgesic prescription and gender development in different regions of Spain. Methods: Cross-sectional study of sex-differences in analgesic prescription according to the gender development of the regions studied. Analgesic prescription, pain and demographic variables were obtained from the Spanish Health Interview Survey in 2006. Gender development was measured with the Gender Development Index (GDI). A logistic regression analysis was conducted to compare analgesic prescription by sex in regions with a GDI above or below the Spanish average. Results: Once adjusted by pain, age and social class, women were more likely to be prescribed analgesics than men, odds ratio (OR) = 1.74 (1.59-1.91), as residents in regions with a lower GDI compared with those in region with a higher GDI: ORWomen = 1.26 (1.12-1.42), ORMen = 1.30 (1.13-1.50). Women experiencing pain in regions with a lower GDI were more likely than men to be treated by a general practitioner rather than by a specialist, OR = 1.32 (1.04-1.67), irrespective of age and social class. Conclusions: Gender bias may be one of the pathways by which inequalities in analgesic treatment adversely affect women's health. Moreover, research into the adequacy of analgesic treatment and the possible medicalisation of women should consider contextual factors, such as gender development.

Innovation in public services: the case of Spanish local government

The present paper aims to determine the level of implementation of innovations in Spanish local government as well as to identify which types of innovations are most common. The paper also considers the link between innovative behavior and organizational size. However, since innovations cannot occur as isolated phenomena but rather as a part of corporate strategy, the study compares the innovative behavior of the local governments analyzed with their typologies or strategic profiles. In order to achieve the aforementioned aims, the paper uses a survey of the Human Resource Managers of Town Halls in the largest Spanish municipalities. The results of this survey show that the most frequent innovations in the local governments analyzed are collaborative; the largest town halls show more propensities to innovate and they focus on external relationships which are collaborative and on the basis on Information and Communication Technologies. The study reconfirms that town halls with a prospective profile are the most innovative.

Salud comunitaria y acción social en el control epidemiológico del tracoma infantil, España (1932-1939)

En el contexto de la endemia tracomatosa que afectó a diversas regiones españolas hasta la década de 1960, se analizan los determinantes epidemiológicos del tracoma infantil y su abordaje desde el modelo de asistencia preventiva que encerraba el concepto de salud comunitaria que se perfiló en el período de entreguerras. La detección precoz de casos, unida a actividades preventivas, educativas, terapéuticas y de inspección, como las que llevaron a cabo las enfermeras visitadoras, contribuyeron al control de la enfermedad. Los resultados reafirman la validez de las estrategias de intervención horizontal de mejora de las condiciones higiénicas y de los factores medioambientales que explicaban la prevalencia del tracoma.

A neural network algorithm to simplify 2D meshes

In this paper we propose a neural network model to simplify and 2D meshes. This model is based on the Growing Neural Gas model and is able to simplify any mesh with different topologies and sizes. A triangulation process is included with the objective to reconstruct the mesh. This model is applied to some problems related to urban networks.

Fate and Transport of Naproxen in a Sandy Aquifer Material: Saturated Column Studies and Model Evaluation

Naproxen-C14H14O3 is a nonsteroidal anti-inflammatory drug which has been found at detectable concentrations in wastewater, surface water, and groundwater. Naproxen is relatively hydrophilic and is in anionic form at pH between 6 and 8. In this study, column experiments were performed using an unconsolidated aquifer material from an area near Barcelona (Spain) to assess transport and reaction mechanisms of Naproxen in the aquifer matrix under different pore water fluxes. Results were evaluated using HYDRUS-1D, which was used to estimate transport parameters. Batch sorption isotherms for Naproxen conformed with the linear model with a sorption coefficient of 0.42 (cm3 g−1), suggesting a low sorption affinity. Naproxen breakthrough curves (BTCs) measured in soil columns under steady-state, saturated water flow conditions displayed similar behavior, with no apparent hysteresis in sorption or dependence of retardation (R, 3.85-4.24) on pore water velocities. Soil sorption did not show any significant decrease for increasing flow rates, as observed from Naproxen recovery in the effluent. Sorption parameters estimated by the model suggest that Naproxen has a low sorption affinity to aquifer matrix. Most sorption of Naproxen occurred on the instantaneous sorption sites, with the kinetic sorption sites representing only about 10 to 40% of total sorption.

Desigualdades de género en la investigación en salud pública y epidemiología en España (2007-2014)

Objetivo: Analizar las desigualdades de género en investigación en salud pública y epidemiología en España, en el periodo 2007-2014. Método: Estudio descriptivo según sexo de posiciones de liderazgo del Centro de Investigación Biomédica en Red (CIBER), especialmente en el área temática de epidemiología y salud pública (CIBERESP) en 2014; de sociedades científicas de salud pública (SESPAS) y epidemiología (SEE), 2009-2014; y de proyectos de investigación solicitados (13.320) y financiados (4699), e importes de convocatorias de Acción Estratégica en Salud (AES), 2007-2013. Resultados: Existe una clara infrarrepresentación de mujeres líderes y contratadas en investigación de excelencia en salud pública (CIBERESP), con predominio de los hombres en puestos de decisión. Aunque los proyectos de investigación de la Acción Estratégica en Salud (AES) liderados por mujeres han crecido ligeramente entre 2007 y 2013, entre los solicitados no alcanzan el 50%, con excepción de los de la Comisión de Salud Pública. La brecha de género es aún mayor en proyectos financiados. Los proyectos liderados por hombres tienen mayor probabilidad de obtener financiación, alcanzando el 29% en los de salud pública. Persiste una segregación horizontal de género en posiciones de reconocimiento científico en congresos de SESPAS y SEE. Conclusiones: La sobrerrepresentación de líderes masculinos en la investigación en salud pública en España debe entenderse como indicador y consecuencia del androcentrismo en las sociedades científicas y los grupos profesionales. Esta situación sexista pone en riesgo la existencia de productos y servicios innovadores desde la perspectiva de género que den respuestas a necesidades y demandas de toda la sociedad. Se necesitan más mujeres en investigación que tengan incorporada esta perspectiva.

Willingness Towards Continuous Assessment

Among the factors that affect the convergence towards the European Higher Education Area, university teaching staff's motivation is fundamental, and consequently, it is crucial to empirically know what this motivation depends on. In this context, one of the most relevant changes in the teacher-student relationship is assessment. In fact, the transition from a static assessment -focused on only one temporal point (final exam)- to a dynamic assessment, will require changes in thought and action, both on the part of teachers and students. In this line, the objective of this paper is to analyze the determinants of teaching staff's predisposition to the continuous assessment method. Specifically, we consider the following explanatory dimensions: teaching method used (which measures their degree of involvement with the ongoing adaptation process), type of subject (core, compulsory and optional), and teacher's personal characteristics (professional status and gender). The empirical application carried out at the University of Alicante uses Logit Models with Random Coefficients to capture heterogeneity, and shows that "cooperative learning" is a clear-cut determinant of "continuous assessment" as well as "continuous assessment plus final examination". Also, a conspicuous result, which in turn becomes a thought-provoking finding, is that professional status is highly relevant as a teacher's engagement is closely related to prospects of stability. Consequently, the most relevant implications from the results revolve around the way academic institutions can propose and implement inducement for their teaching staff.
