Evolución estructural organizacional de la dirección general de comunicación social y relaciones públicas. Caso: Universidad Autónoma de Nuevo León, México

A sus 77 años de servicio (2010), la UNAL consideró necesaria la creación de un órgano especializado que gestionara los procesos de comunicación y relaciones públicas, con el objeto de responder a este rubro a nivel nacional e iniciar con el proceso de internacionalización; en ese año se realizó un estudio diagnóstico para conocer las necesidades estructurales y proceder al diseño de la estructura organizacional

Análisis de contenido: Tratamiento informativo de la mujer en la prensa.

Esta investigación parte de un análisis del tratamiento informativo sobre la perspectiva de la mujer en la prensa escrita de Nuevo León, hecho por la Universidad Autónoma de Nuevo León, para describir el manejo de la información, como primer paso para determinar la contribución de este medio masivo de información a la formación de actitudes y percepciones sobre la mujer y su discurso. Se realizó un análisis de contenido cuantitativo de 723 notas resumidas, con fichas de información publicada por la prensa escrita y digital de Nuevo León, lo anterior bajo el enfoque de la Declaración de Beijing 1995. El estudio arroja que el 27% de las notas estudiadas en el 2012, manejan implícita o explícitamente el tema violencia, lo que reafirma la urgencia de promover la igualdad, respeto y seguridad a la mujer en el ámbito social

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Measurement of the muon charge asymmetry in inclusive pp to WX production at sqrt(s)=7 TeV and an improved determination of light parton distribution functions

Measurements of the muon charge asymmetry in inclusive pp to WX production at sqrt(s)=7 TeV are presented. The data sample corresponds to an integrated luminosity of 4.7 inverse femtobarns recorded with the CMS detector at the LHC. With a sample of more than twenty million W to mu nu events, the statistical precision is greatly improved in comparison to previous measurements. These new results provide additional constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10E-3 to 10E-1. These measurements and the recent CMS measurement of associated W + charm production are used together with the cross sections for inclusive deep inelastic ep scattering at HERA in a next-to-leading-order QCD analysis. The determination of the valence quark distributions is improved, and the strange-quark distribution is probed directly through the leading-order process g + s to W + c in proton-proton collisions at the LHC

Determination of the top-quark pole mass and strong coupling constant from the ttˉt\bar{t} production cross section in pp collisions at s\sqrt{s} = 7 TeV

The inclusive cross section for top-quark pair production measured by the CMS experiment in proton-proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order with various parton distribution functions to determine the top-quark pole mass, $m_t^{pole}$, or the strong coupling constant, $\alpha_S$. With the parton distribution function set NNPDF2.3, a pole mass of 176.7$^{+3.8}_{-3.4}$ GeV is obtained when constraining $\alpha_S$ at the scale of the Z boson mass, $m_Z$, to the current world average. Alternatively, by constraining $m_t^{pole}$ to the latest average from direct mass measurements, a value of $\alpha_S(m_Z)$ = 0.1151$^{+0.0033}_{-0.0032}$ is extracted. This is the first determination of $\alpha_S$ using events from top-quark production
