Kant y el problema de las mujeres: una revisión feminista de las posibilidades de su inclusión cívica

The aim of this paper is to evaluate the possibility of harmonizing Kant’s juridical-political thought with a feministperspective of women’s emancipation. To this end, first of all, the mechanisms by which the author deprives women of the abilityto guide their behavior by principles of reason will be analyzed. Consequently, it will be argued that women’s moral inferiorityis the cause of their political or civic inferiority. Secondly, once this link has been made, the viability of a conciliation will beanalyzed, taking into account the consequences that this would bring about in the sexual division by spheres and in the fact ofthinking of political subjects as disincarnated subjects.The aim of this paper is to evaluate the possibility of harmonizing Kant’s juridical-political thought with a feministperspective of women’s emancipation.

Child and adolescent anxiety: investigating temporal trends and explanatory factors

Emerging evidence indicates that the prevalence of child and adolescent psychiatric symptoms and disorders increased in the twenty-first century. However, few studies have focused on recent time trends in the prevalence of anxiety disorders among United States (US) children and adolescents specifically. Relatedly, an open question in the field is what factors are driving increases in reported mental health symptoms and disorders, including anxiety, among US youth. To this end, this study uses data from the National Survey on Children’s Health, a nationally representative cross-sectional survey of US parents and caregivers, to assess recent temporal trends in anxiety disorders among US children and adolescents. This study also tests associations between multiple social ecological factors (i.e., socioeconomic status, physical health, family composition, parental mental health, and neighborhood disadvantage) and youth anxiety at each survey year. Overall, results indicated that among US 6 to 17-year-olds the prevalence of parent-reported lifetime anxiety or depression increased from 5.4% to 8.3% between 2003 to 2011/12. The estimated prevalence of parent-reported lifetime anxiety rose from 10.0% to 11.5% between 2016 and 2018 among US children and adolescents aged 6 to 17. The estimated prevalence of parent-reported current anxiety increased from 8.5% to 9.5% between 2016 and 2018. Additionally, several socioecological factors at the individual- and family-level were associated with youth anxiety at each survey year. Results suggest that ongoing collaboration amongst parents/caregivers, physicians, mental health providers, and school staff might help identify at-risk youth, as well as inform the need for effective prevention and intervention strategies and guide best practices for these strategies

Isocyanurate transformation induced healing of isocyanurate–oxazolidone polymers

Isocyanurate–oxazolidone (ISOX) polymers have been reported as a novel, intrinsically self‐healable thermoset, and their healing mechanism under the effect of nucleophiles, such as tertiary amines and pyridines during polymerization, is thoroughly investigated in this study. This work provides evidence that the healing behavior of the polymers results part from the transformation of isocyanurate to oxazolidone on the fracture surfaces of the ISOX polymers at elevated temperatures. The isocyanurate transformation is characterized by chemical composition of the ISOX polymers before and after a predetermined healing procedure, through a combination characterization of Fourier transform infrared spectroscopy and carbon nuclear magnetic resonance spectroscopy. From the chemical composition of the ISOX polymers, an increased oxazolidone fraction is observed after the healing event, which verifies the hypothesized healing mechanism. By correlating the change in oxazolidone fraction in the polymers during the healing event, with the corresponding healing performance of the polymers, healing efficiencies of the polymers are shown to be inversely proportional to the ratio of oxazolidone to isocyanurate in the polymers. The transformation to oxazolidone is also shown to be dependent on two variables, nucleophilicity of the polymerization catalyst and duration of the postcure. The isocyanate and epoxide polymerization mechanism in the presence of nucleophiles is also investigated to explain the effect of the catalyst nucleophilicity on the chemical composition as well as the healing performance of the ISOX polymers. © 2019 Wiley Periodicals, Inc.

Supernova type Ia luminosities, their dependence on second parameters, and the value of H_0

A sample of 35 SNe Ia with good to excellent photometry in B and V, minimum internal absorption, and 1200 < v < \approx 30000 km/s is compiled from the literature. As far as their spectra are known they are all Branch-normal. For 29 of the SNe Ia also peak magnitudes in I are known. The SNe Ia have uniform colors at maximum, i.e. =-0.012 mag (sigma=0.051) and =-0.276 mag (sigma=0.078). In the Hubble diagram they define a Hubble line with a scatter of $\sigma_M$=0.21-0.16 mag, decreasing with wavelength. The scatter is further reduced if the SNe Ia are corrected for differences in decline rate Delta_m_15 or color (B-V). A combined correction reduces the scatter to sigma<=0.13 mag. After the correction no significant dependence remains on Hubble type or galactocentric distance. The Hubble line suggests some curvature which can be differently interpreted. A consistent solution is obtained for a cosmological model with Omega_M=0.3, Omega_Lambda=0.7, which is indicated also by much more distant SNe Ia. Absolute magnitudes are available for eight equally blue (Branch-normal) SNe Ia in spirals, whose Cepheid distances are known. If their well defined mean values of M_B, M_V, and M_I are used to fit the Hubble line to the above sample of SNe Ia one obtains H_0=58.3 km/s/Mpc, or, after adjusting all SNe Ia to the average values of Delta_m_15 and (B-V), H_0=60.9 km/s/Mpc. Various systematic errors are discussed whose elimination tends to decrease H_0. The finally adopted value at the 90-percent level, including random and systematic errors, is H_0=58.5 +/- 6.3 km/s/Mpc. Several higher values of H_0 from SNe Ia, as suggested in the literature, are found to depend on large corrections for variations of the light curve parameter and/or on an unwarranted reduction of the Cepheid distances of the calibrating SNe Ia.Comment: 42 pages, including 9 figures; submitted to Ap

Molybdenum sputtering film characterization for high gradient accelerating structures

Technological advancements are strongly required to fulfill the demands of new accelerator devices with the highest accelerating gradients and operation reliability for the future colliders. To this purpose an extensive R&D regarding molybdenum coatings on copper is in progress. In this contribution we describe chemical composition, deposition quality and resistivity properties of different molybdenum coatings obtained via sputtering. The deposited films are thick metallic disorder layers with different resistivity values above and below the molibdenum dioxide reference value. Chemical and electrical properties of these sputtered coatings have been characterized by Rutherford backscattering, XANES and photoemission spectroscopy. We will also present a three cells standing wave section coated by a molybdenum layer $\sim$ 500 nm thick designed to improve the performance of X-Band accelerating systems.Comment: manuscript has been submitted and accepted by Chinese Physics C (2012
