Sociología del campo filosófico español entre el Franquismo y la Transición democrática: una validación cuantitativa

La más reciente investigación dedicada al análisis del campo filosófico español entre el tardofranquismo y la Transición, señaló la existencia de dos redes intelectuales: una, denominada «oficial», que aglutinaba a los filósofos de perfil más estrictamente académico (v. g. Sergio Rábade), y otra, designada como «alternativa», que integraba a los pensadores más vanguardistas (v. g. López Aranguren). Los materiales utilizados en La filosofía española. Herederos y pretendientes. Una lectura sociológica (1963-1990) (Vázquez García 2009), fueron objeto en esta obra de una aproximación cualitativa. Nuestro objetivo en este artículo, privilegiando la fiabilidad sobre la validez, es la realización de un análisis de correspondencias múltiples, en el que se han cuantificado más de 15 variables sobre cincuenta filósofos españoles. En las conclusiones se profundiza en las diferencias y similitudes entre los resultados obtenidos con las metodologías cualitativa y cuantitativ

[Determinants of the use of different healthcare levels in the General System of Social Security in Health in Colombia and the Unified Health System in Brazil].

OBJECTIVE: To compare the use of different healthcare levels, and its determinants, in two different health systems, the General System of Social Security in Health (GSSSH) and the Unified Health System (UHS) in municipalities in Colombia and Brazil. METHODS: A cross-sectional study was carried out, based on a population survey in two municipalities in Colombia (n=2163) and two in Brazil (n=2155). Outcome variables consisted of the use of primary care services, outpatient secondary care services, and emergency care in the previous 3 months. Explanatory variables were need and predisposing and enabling factors. Bivariate and multivariate logistic regression analyses were performed by healthcare level and country. RESULTS: The determinants of use differed by healthcare level and country: having a chronic disease was associated with a greater use of primary and outpatient secondary care in Colombia, and was also associated with the use of emergency care in Brazil. In Colombia, persons enrolled in the contributory scheme more frequently used the services of the GSSSH than persons enrolled with subsidized contributions in primary and outpatient secondary care and more than persons without insurance in any healthcare level. In Brazil, the low-income population and those without private insurance more frequently used the UHS at any level. In both countries, the use of primary care was increased when persons knew the healthcare center to which they were assigned and if they had a regular source of care. Knowledge of the referral hospital increased the use of outpatient secondary care and emergency care. CONCLUSIONS: In both countries, the influence of the determinants of use differed according to the level of care used, emphasizing the need to analyze healthcare use by disaggregating it by level of care

Phytochemicals as antibiotic alternatives to promote growth and enhance host health

There are heightened concerns globally on emerging drug-resistant superbugs and the lack of new antibiotics for treating human and animal diseases. For the agricultural industry, there is an urgent need to develop strategies to replace antibiotics for food-producing animals, especially poultry and livestock. The 2nd International Symposium on Alternatives to Antibiotics was held at the World Organization for Animal Health in Paris, France, December 12-15, 2016 to discuss recent scientific developments on strategic antibiotic-free management plans, to evaluate regional differences in policies regarding the reduction of antibiotics in animal agriculture and to develop antibiotic alternatives to combat the global increase in antibiotic resistance. More than 270 participants from academia, government research institutions, regulatory agencies, and private animal industries from >25 different countries came together to discuss recent research and promising novel technologies that could provide alternatives to antibiotics for use in animal health and production; assess challenges associated with their commercialization; and devise actionable strategies to facilitate the development of alternatives to antibiotic growth promoters (AGPs) without hampering animal production. The 3-day meeting consisted of four scientific sessions including vaccines, microbial products, phytochemicals, immune-related products, and innovative drugs, chemicals and enzymes, followed by the last session on regulation and funding. Each session was followed by an expert panel discussion that included industry representatives and session speakers. The session on phytochemicals included talks describing recent research achievements, with examples of successful agricultural use of various phytochemicals as antibiotic alternatives and their mode of action in major agricultural animals (poultry, swine and ruminants). Scientists from industry and academia and government research institutes shared their experience in developing and applying potential antibiotic-alternative phytochemicals commercially to reduce AGPs and to develop a sustainable animal production system in the absence of antibiotics.Fil: Lillehoj, Hyun.

Manipulation of domain wall dynamics in amorphous microwires through the magnetoelastic anisotropy

We studied the effect of magnetoelastic anisotropy on domain wall (DW) dynamics and remagnetization process of magnetically bistable Fe-Co-rich microwires with metallic nucleus diameters (from 1.4 to 22 μm). We manipulated the magnetoelastic anisotropy applying the tensile stresses and changing the magnetostriction constant and strength of the internal stresses. Microwires of the same composition of metallic nucleus but with different geometries exhibit different magnetic field dependence of DW velocity with different slopes. Application of stresses resulted in decrease of the DW velocity, v, and DW mobility, S. Quite fast DW propagation (v until 2,500 m/s at H about 30 A/m) has been observed in low magnetostrictive magnetically bistable Co(56)Fe(8)Ni(10)Si(10)B(16) microwires. Consequently, we observed certain correlation between the magnetoelastic energy and DW dynamics in microwires: decreasing the magnetoelastic energy, K(me), DW velocity increases

Measurement of the Bottom-Strange Meson Mixing Phase in the Full CDF Data Set

We report a measurement of the bottom-strange meson mixing phase \beta_s using the time evolution of B0_s -> J/\psi (->\mu+\mu-) \phi (-> K+ K-) decays in which the quark-flavor content of the bottom-strange meson is identified at production. This measurement uses the full data set of proton-antiproton collisions at sqrt(s)= 1.96 TeV collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.6 fb-1 of integrated luminosity. We report confidence regions in the two-dimensional space of \beta_s and the B0_s decay-width difference \Delta\Gamma_s, and measure \beta_s in [-\pi/2, -1.51] U [-0.06, 0.30] U [1.26, \pi/2] at the 68% confidence level, in agreement with the standard model expectation. Assuming the standard model value of \beta_s, we also determine \Delta\Gamma_s = 0.068 +- 0.026 (stat) +- 0.009 (syst) ps-1 and the mean B0_s lifetime, \tau_s = 1.528 +- 0.019 (stat) +- 0.009 (syst) ps, which are consistent and competitive with determinations by other experiments.Comment: 8 pages, 2 figures, Phys.

The α1-adrenergic receptors: diversity of signaling networks and regulation

The α1-adrenergic receptor (AR) subtypes (α1a, α1b, and α1d) mediate several physiological effects of epinephrineand norepinephrine. Despite several studies in recombinant systems and insightfrom genetically modified mice, our understanding of the physiological relevance and specificity of the α1-AR subtypes is still limited. Constitutive activity and receptor oligomerization have emerged as potential features regulating receptor function. Another recent paradigm is that βarrestins and G protein-coupled receptors themselves can act as scaffolds binding a variety of proteins and this can result in growing complexity of the receptor-mediated cellular effects. The aim of this review is to summarize our current knowledge on some recently identified functional paradigms and signaling networks that might help to elucidate the functional diversity of the α1-AR subtypes in various organs

Psychological characteristics of aggressors of young couple

[EN] Violence against women in relationships young people has become in recent years a public health problem of major social. This article, with a view to the prevention, seeks to address the psychological characteristics of the perpetrator of pair in young relations. An initial review of the personality features investigated in previous studies and their influence on violent behaviour was carried out. Following this, an empirical study on a sample of young people was performed. Methods: We conducted a study with 100 young people of Valencia. Of these, 50 are young offenders and 50 couple, young students of compulsory secondary education. Data are obtained and analyzed psychological characteristics differences between groups. Results: The study conducted shows that in general, young offenders have one hand high scores on neuroticism, impulsivity, external locus of control, psychoticism and antisocial behavior. Furthermore show low scores on self-control, empathy, selfesteem and frustration tolerance Conclusions: The results of this paper make it abundantly clear that violence in young relationships is important enough to be considered from different sectors of society and justifies the need to develop and implement prevention programs adapted adolescents and their characteristics.[ES] La violencia contra la mujer en relaciones de pareja jóvenes se ha convertido en los últimos tiempos en un problema de salud pública de gran envergadura social. Este artículo, de cara a la prevención, trata de abordar las características psicológicas del agresor en parejas jóvenes. En primer lugar se hace una revisión de las características de personalidad investigadas en estudios previos y su influencia en el comportamiento violento. Después se aportan datos de un estudio empírico realizado por nuestro equipo de investigación con una muestra de jóvenes de la Comunidad Valenciana. Método: El estudio llevado a cabo cuenta con 100 jóvenes de la Comunidad Valenciana. De ellos, 50 son jóvenes agresores de pareja y otros 50, jóvenes estudiantes de Educación Secundaria Obligatoria. Se obtienen datos de características psicológicas y se analizan las diferencias entre ambos grupos. Resultados: Los datos muestran que generalmente, los jóvenes agresores presentan puntuaciones elevadas en neuroticismo, impulsividad, locus de control externo, psicoticismo, conducta antisocial y puntuaciones bajas en autocontrol, empatía, autoestima y tolerancia a la frustración. Conclusiones: Los resultados del presente trabajo dejan muy claro que la violencia en relaciones de pareja jóvenes tiene la suficiente importancia como para ser tenida en cuenta desde los diferentes sectores de la sociedad y se justifica la necesidad de elaborar y poner en práctica programas de prevención adaptados a los adolescentes y a sus características peculiaresHernández Jiménez, MJ.
