The galaxy-halo connection of DESI luminous red galaxies with subhalo abundance matching

We use subhalo abundance and age distribution matching to create magnitude-limited mock galaxy catalogs at $z\sim0.43$, $0.52$, and $0.63$ with $z$-band and $3.4$ micron $W1$-band absolute magnitudes and ${r-z}$ and ${r-W1}$ colors. From these magnitude-limited mocks we select mock luminous red galaxy (LRG) samples according to the $(r-z)$-based (optical) and $(r-W1)$-based (infrared) selection criteria for the LRG sample of the Dark Energy Spectroscopic Instrument (DESI) Survey. Our models reproduce the number densities, luminosity functions, color distributions, and projected clustering of the DESI Legacy Surveys that are the basis for DESI LRG target selection. We predict the halo occupation statistics of both optical and IR DESI LRGs at fixed cosmology, and assess the differences between the two LRG samples. We find that IR-based SHAM modeling represents the differences between the optical and IR LRG populations better than using the $z$-band, and that age distribution matching overpredicts the clustering of LRGs, implying that galaxy color is uncorrelated with halo age in the LRG regime. Both the optical and IR DESI LRG target selections exclude some of the most luminous galaxies that would appear to be LRGs based on their position on the red sequence in optical color-magnitude space. Both selections also yield populations with a non-trivial LRG-halo connection that does not reach unity for the most massive halos. We find the IR selection achieves greater completeness ($\gtrsim 90\%$) than the optical selection across all redshift bins studied.Comment: 20 pages, 14 figures, submitted to Ap

Modeling Initial Participation of Diverse Communities in Competitive Swimming

This research note introduces the Initial Participation Model, which theorizes continued participation in a activity or group before individuals make commitment is a function of: enjoyment, feeling of inclusion, and/or involvement opportunities. The specific focus of this research is investigating how deficiency in enjoyment, feeling of inclusion, and involvement opportunities may discourage continuing participation in competitive swimming by underrepresented populations such as African American, Black, Hispanic, Latino, Native American, Pacific Islander and low-socioeconomic communities. Details explain how initial participation differs from other sport stages by emphasizing participation; relating to program instead of sport; and resetting each time an individual joins a new activity or group. Two examples are offered illustrating how the model may be used for identifying points of intervention that stimulate continued initial participation. Also included are specific factors constructing the model and future testing plans for validation

Como resultado se estableció una asociación negativa muy fuerte y estadísticamente significativa entre ambas variables (rs=-,985) y con un tamaño del efecto grande (r2= 0.970 ). Se concluye que a mayores experiencias de sexting existen menores niveles de bienestar psicológico en los jóvenes evaluados

MicroRNAs in systemic rheumatic diseases

MicroRNAs (miRNAs) are endogenous, non-coding, single-stranded RNAs about 21 nucleotides in length. miRNAs have been shown to regulate gene expression and thus influence a wide range of physiological and pathological processes. Moreover, they are detected in a variety of sources, including tissues, serum, and other body fluids, such as saliva. The role of miRNAs is evident in various malignant and nonmalignant diseases, and there is accumulating evidence also for an important role of miRNAs in systemic rheumatic diseases. Abnormal expression of miRNAs has been reported in autoimmune diseases, mainly in systemic lupus erythematosus and rheumatoid arthritis. miRNAs can be aberrantly expressed even in the different stages of disease progression, allowing miRNAs to be important biomarkers, to help understand the pathogenesis of the disease, and to monitor disease activity and effects of treatment. Different groups have demonstrated a link between miRNA expression and disease activity, as in the case of renal flares in lupus patients. Moreover, miRNAs are emerging as potential targets for new therapeutic strategies of autoimmune disorders. Taken together, recent data demonstrate that miRNAs can influence mechanisms involved in the pathogenesis, relapse, and specific organ involvement of autoimmune diseases. The ultimate goal is the identification of a miRNA target or targets that could be manipulated through specific therapies, aiming at activation or inhibition of specific miRNAs responsible for the development of disease

Percepción de la calidad de servicio del evento gastronómico internacional Mistura periodo 2014

Hoy en día la calidad de servicio es un elemento fundamental en la gestación de las empresas, Es así que la calidad de servicio está conformado por los elementos tangibles e intangibles que perciben los consumidores al recibir un servicio. Si en las organizaciones, todos estuvieran conscientes que la calidad es un progreso que de alguna manera asegura la permanencia en el mercado e incrementa las utilidades, pueda lograrse que todos conviertan a esta en un estilo de vida, que conlleva en familiarizarse y conocer a los clientes en sus gustos, comodidades, preferencias y lo más importante poder obtener una opinión de ellos para lograr mejoras continuas en la empresa. Por tal motivo la presente investigación desarrolla un estudio sobre como los usuarios perciben calidad de servicio en el evento gastronómico Mistura 2014. El diseño de estudio es descriptiva simple y la muestra se constituyó por 114 asistentes a este evento, donde las edades oscilan entre 23 a 64 años de edad; asimismo se evaluaron a 49 varones y 65 mujeres. A quienes se les aplico el Cuestionario de percepción de calidad de servicio Servqual de Parasuraman, Zeithmahl y Berry (1991). El instrumento compara las expectativas frente a las percepciones del consumidor y se encuentra representado por un cuestionario de 22 preguntas que mide la calidad de un servicio y que se basa en las percepciones y expectativas del consumidor. Los resultados de la investigación mostraron que existe una predominancia del nivel bajo (46.5%) de la calidad de servicio

Indirect effects of paediatric conjugate vaccines on invasive pneumococcal disease in older adults

Objectives: The aim of this study was to assess the indirect effect of paediatric 13-valent pneumococcal conjugate vaccine (PCV13) vaccination on people ≥65 years of age with invasive pneumococcal disease (IPD) in Catalonia and to determine factors predictive of mortality. Methods: During 2014-2016, 1285 IPD cases were reported to the Public Health Agency of Catalonia. The indirect effect of paediatric PCV13 vaccination was calculated by comparing the incidence rate (IR) in 2016 (PCV13 year) with that in 2009 (pre-PCV13). Predictors of mortality were determined using multivariate logistic regression. Results: Comparing 2016 and 2009, IPD decreased by 19% (IR 40.1 and 32.5 per 100 000 person-years, respectively). PCV13 serotypes decreased by 57% (IR 23.7 and 10.1), while non-PCV13 serotypes increased by 36% (IR 16.4 and 22.4). During 2014-2016, the mortality rate was 17.5%, and mortality was associated with age ≥85 years (adjusted odds ratio (aOR) 2.91, 95% confidence interval (CI) 1.89, 4.48), meningitis (aOR 2.29, 95% CI 1.25, 4.19), non-focal bacteraemia (aOR 3.73, 95% CI 2.00, 6.94), and ≥1 high-risk condition (aOR 1.89, 95% CI 1.08, 3.32). PPV23non13 serotypes were associated with lower mortality than PCV13 serotypes (aOR 0.54, 95% CI 0.34, 0.86). Conclusions: The incidence of IPD in people ≥65 years of age decreased after the introduction of paediatric PCV13, and this was due to a reduction in PCV13 serotypes, although an increase in non-PCV13 serotypes was observed. Mortality was associated with age, meningitis, non-focal bacteraemia, ≥1 high-risk condition, and PCV13 serotypes

Norovirus outbreaks in long-term care facilities in Catalonia from 2017 to 2018

Norovirus is the leading cause of outbreaks of acute viral gastroenteritis. We carried out this study to investigate outbreaks in long-term care facilities reported in 2017 and 2018 in Catalonia (Spain). The characteristics of the centers, exposed persons and the genogroups responsible were analyzed. Viral loads were estimated. The attack rate (AR) of the outbreaks studied, and the rate ratio (RR) and the odds ratio (OR) and their 95% confdence intervals as measures of association were calculated. The mean cycle thresholds were compared using the t-test for independent means. We included 30 outbreaks (4631 exposed people). The global AR was 25.93%. The RR of residents vs. staf was 2.28 (95% CI 2.0-2.6). The RR between AR in residents with total or severe dependence vs. residents with moderate, low or no-dependence was 1.23 (95% CI 1.05-1.45). The AR were higher in smaller centers than in larger ones (38.47% vs. 19.25% and RR 2; 95% CI 1.82-2.2). GII was responsible for 70% of outbreaks. No association was found between the genogroup and presenting symptoms (OR 0.96; 95% CI 0.41-2.26). Viral loads were higher in symptomatic than in asymptomatic patients (p = 0.001)

Determinar las causas por las cuales las capacitaciones no influyen positivamente en la disminución de la accidentalidad del personal encargado de las labores de recolección y cosecha en Elixir LTDA en el año 2019.En el presente trabajo nos dispusimos a analizar las características y calidad de las capacitaciones en Seguridad y Salud ocupacional, regidas en la empresa agrícola Elixir LTDA.. Para esto, hemos usado la metodología de Kirkpatrick que busca en 4 pasos secuenciales verificar como los conocimientos generados en la capacitación se transforman (o no) en resultados prácticos. Al aplicar este método en la empresa Elixir LTDA hemos concluido que los trabajadores no se sienten suficientemente motivados para cumplir con las regulaciones de Seguridad y Salud en el trabajo. Es en ese sentido que hemos propuesto la aplicación de un modelo de capacitación Andragogico en la empresa, que coloca al trabajador en el centro del sistema de enseñanza y aumenta su nivel de motivación

Three new bricks in the wall: Berkeley 23, Berkeley 31, and King 8

A comprehensive census of Galactic open cluster properties places unique constraints on the Galactic disc structure and evolution. In this framework we investigate the evolutionary status of three poorly-studied open clusters, Berkeley 31, Berkeley 23 and King 8, all located in the Galactic anti-centre direction. To this aim, we make use of deep LBT observations, reaching more than 6 mag below the main sequence Turn- Off. To determine the cluster parameters, namely age, metallicity, distance, reddening and binary fraction, we compare the observational colour-magnitude diagrams (CMDs) with a library of synthetic CMDs generated with different evolutionary sets (Padova, FRANEC and FST) and metallicities. We find that Berkeley 31 is relatively old, with an age between 2.3 and 2.9 Gyr, and rather high above the Galactic plane, at about 700 pc. Berkeley 23 and King 8 are younger, with best fitting ages in the range 1.1-1.3 Gyr and 0.8-1.3 Gyr, respectively. The position above the Galactic plane is about 500- 600 pc for the former, and 200 pc for the latter. Although a spectroscopic confirmation is needed, our analysis suggests a sub-solar metallicity for all three clusters.Comment: 17 Pages, Accepted for publication in MNRA
