EMOTIONAL LABOR: HOW GENDERED RACISM AFFECTS AFRICAN AMERICAN WOMEN WORKING IN MENTAL HEALTH CRISIS RESPONSE
The research uses the framework of emotional labor to analyze the effect of gendered racism on mental health, physical well-being, and burn out of African American women who provide mental health crisis response. The focus on the emotional toll an African American woman experiences while dealing with clients who may respond with racist and/or sexist actions or words. Also explored are coping strategies and protective factors while managing the stressors of sexism and racism while working in a mental health crisis response. The study uses in- depth interviews to explore the lived experiences of African American/Black women. Axial coding links emerging themes of the effect of gendered racism and emotional labor on Black women working in crisis response. A post-positive and qualitative design assisted in exploring the cost of emotional labor on Black women and coping strategies used when faced with the specific triangulation of oppression, gendered racism, and crisis work. Findings are that women utilize friends and coworkers to debrief and process gendered racism on the job. Also, the majority of women interviewed cited healthy coping skills and unhealthy coping skills as a way to minimize and compartmentalize gendered racism while working
Properties of Magnetized Quark-Hybrid Stars
The structure of a magnetized quark-hybrid stars (QHS) is modeled using a
standard relativistic mean-field equation of state (EoS) for the description of
hadronic matter. For quark matter we consider a bag model EoS which is modified
perturbatively to account for the presence of a uniform magnetic field. The
mass-radius (M-R) relationship, gravitational redshift and rotational Kepler
periods of such stars are compared with those of standard neutron stars (NS).Comment: 5 pages, 2 figures, prepared for the 2nd International Symposium on

Only in the people we trust": The moral structure of the Chilean urban poor's radical political discourse in the Partido Igualdad
IndexaciĂłn: Scopus; Scielo.En el presente artĂculo, se analiza la estructura del discurso polĂtico radical de los pobladores chilenos, a travĂ©s del caso del Partido Igualdad. La hipĂłtesis que orienta este artĂculo es que el discurso que vehiculiza el Partido tiene una lĂłgica populista centrada en el significante pueblo y elementos anti-elitistas. Si bien esta estructura coincide con la literatura contemporánea acerca del populismo, el significante pueblo estarĂa limitado por otros dos significantes: el “sufrimiento compartido” y la “dignidad”, lo que restringe sus posibilidades de articulaciĂłn.In the present article, the structure of the radical political discourse of the Chilean squatters is analyzed through the case of the Partido Igualdad. The hypothesis that guides the article is that the discourse of the party has a populist logic centered on the signifier “the people” and anti-elitist elements. Although this structure coincides with contemporary literature about populism, the signifier “the people” would be limited by two other signifiers: "shared suffering" and "dignity", which restricts their possibilities of articulation.http://www.izquierdas.cl/images/pdf/2019/n46/art2.pd
Measuring Security Price Performance Using Chilean Daily Stock Returns: The event Study Method
24 p.Siguiendo el enfoque de simulaciĂłn de Brown y Warner y usando retornos diarios del mercado accionario chileno,examinamos la especificaciĂłn y el poder de tres estadĂsticos comĂşnmente utilizados en estudios de evento: el test estandarizado,el de corte transversal y el de portfolio. Nuestros resultados muestran que aunque los retornos y excesos de retornos a nivel
individual evidentemente no distribuyen normal, la media muestral converge hacia la normalidad en la medida que el nĂşmero de acciones del portfolio muestral aumenta. AsĂ, las pruebas estadĂsticas tĂpicamente utilizadas en estudios de evento de un dĂa estarĂan bien especificadas, al menos para un nivel de significancia del 5%. En tĂ©rminos del poder del test, el test estandarizado siempre se muestra más poderoso para capturar la presencia de un retorno anormal que sus dos competidores: el test de corte
transversal y el de portfolio. TambiĂ©n encontramos, sin embargo, que el poder de las tres pruebas estadĂsticas analizadas es muy
sensible tanto al tamaño muestral como al nĂşmero de dĂas que involucre el evento
Norovirus Infection and Disease in an Ecuadorian Birth Cohort: Association of Certain Norovirus Genotypes With Host FUT2 Secretor Status.
BACKGROUND: Although norovirus is the most common cause of gastroenteritis, there are few data on the community incidence of infection/disease or the patterns of acquired immunity or innate resistance to norovirus. METHODS: We followed a community-based birth cohort of 194 children in Ecuador with the aim to estimate (1) the incidence of norovirus gastroenteritis from birth to age 3 years, (2) the protective effect of norovirus infection against subsequent infection/disease, and (3) the association of infection and disease with FUT2 secretor status. RESULTS: Over the 3-year period, we detected a mean of 2.26 diarrheal episodes per child (range, 0-12 episodes). Norovirus was detected in 260 samples (18%) but was not found more frequently in diarrheal samples (79 of 438 [18%]), compared with diarrhea-free samples (181 of 1016 [18%]; P = .919). A total of 66% of children had at least 1 norovirus infection during the first 3 years of life, and 40% of children had 2 infections. Previous norovirus infections were not associated with the risk of subsequent infection. All genogroup II, genotype 4 (GII.4) infections were among secretor-positive children (P < .001), but higher rates of non-GII.4 infections were found in secretor-negative children (relative risk, 0.56; P = .029). CONCLUSIONS: GII.4 infections were uniquely detected in secretor-positive children, while non-GII.4 infections were more often found in secretor-negative children
Density-Matrix functional theory of strongly-correlated lattice fermions
A density functional theory (DFT) of lattice fermion models is presented,
which uses the single-particle density matrix gamma_{ij} as basic variable. A
simple, explicit approximation to the interaction-energy functional W[gamma] of
the Hubbard model is derived from exact dimer results, scaling properties of
W[gamma] and known limits. Systematic tests on the one-dimensional chain show a
remarkable agreement with theBethe-Ansatz exact solution for all interaction
regimes and band fillings. New results are obtained for the ground-state
energyand charge-excitation gap in two dimensions. A successful description of
strong electron correlations within DFT is achieved.Comment: 15 pages, 6 figures Submitted to PR
Synthesis, physicochemical and photophysical characterization of 4-(1-Pyrenyl)-Butyl-α-d-mannopyranoside
IndexaciĂłn: Web of Science; Scopus; Scielo.Glycolipids are biomolecules composed of a lipid chain (lipophilic) and a monosaccharide or oligosaccharide as hydrophilic group. Their chemical structure and biological role make them undoubtedly good candidates for a large and continuously growing number of biotechnological applications. Mannose is a carbohydrate present on membrane glycolipids of a wide number of pathogenic microorganisms (bacteria, fungi, protozoa, and viruses) and specifically recognized by several lectins. We synthesized a mannose derivative linked through a short methylene chain to a pyrene moiety which behaves as a surfactant, able to aggregate, and retains the photophysical properties of pyrene: showing comparable absorption and emission spectra, having lower fluorescence quantum yield and the ability to form excimer, and finally the ability to produce O-2((1)Delta(g)) with high quantum yields. Thus, this novel molecule would open future applications for detection (fluorescence) or inactivation (singlet oxygen) of bacterial pathogens, viruses, tumor cells, or particular cells.http://ref.scielo.org/pcn4d
