    “I don’t want to look sick skinny”: Perceptions of body image and weight loss in Hispanics living with HIV in South Texas

    Objective: Obesity is rising in people with HIV (PLWH) and Hispanics. Both HIV and obesity are associated with cardiovascular disease morbidity and mortality. Our goal is to understand perceptions of body image and lifestyle in Hispanics with HIV to adapt interventions appropriately. Methods: We conducted semi-structured interviews with 22 Hispanic PLWH and 6 providers. Purposive sampling selected patient participants across weights and genders. Interviews were coded and analyzed using grounded theory, comparing perspectives between patients with and without obesity, and patients and providers. Results: Participants felt obesity and diabetes were “normal” in the community. Patients exhibited understanding of healthy diet and lifestyle but felt incapable of maintaining either. Traditionally Hispanic foods were blamed for local obesity prevalence. Five patients equated weight with health and weight loss with illness, and four expressed concerns that weight loss could lead to unintentional disclosure of HIV status. Participants with overweight or obesity expressed awareness of their weight and felt shamed by providers. Providers found weight loss interventions to be ineffective. Conclusion: Interventions in this population must address identified barriers: overweight/obesity as a normative value, lack of self-efficacy, cultural beliefs surrounding food, fear of HIV-associated weight loss and stigma, and provider perspectives on intervention futility

    Optimized Multi-Frequency Spectra for Applications in Radiative Feedback and Cosmological Reionization

    Full text link
    The recent implementation of radiative transfer algorithms in numerous hydrodynamics codes has led to a dramatic improvement in studies of feedback in various astrophysical environments. However, because of methodological limitations and computational expense, the spectra of radiation sources are generally sampled at only a few evenly-spaced discrete emission frequencies. Using one-dimensional radiative transfer calculations, we investigate the discrepancies in gas properties surrounding model stars and accreting black holes that arise solely due to spectral discretization. We find that even in the idealized case of a static and uniform density field, commonly used discretization schemes induce errors in the neutral fraction and temperature by factors of two to three on average, and by over an order of magnitude in certain column density regimes. The consequences are most severe for radiative feedback operating on large scales, dense clumps of gas, and media consisting of multiple chemical species. We have developed a method for optimally constructing discrete spectra, and show that for two test cases of interest, carefully chosen four-bin spectra can eliminate errors associated with frequency resolution to high precision. Applying these findings to a fully three-dimensional radiation-hydrodynamic simulation of the early universe, we find that the HII region around a primordial star is substantially altered in both size and morphology, corroborating the one-dimensional prediction that discrete spectral energy distributions can lead to sizable inaccuracies in the physical properties of a medium, and as a result, the subsequent evolution and observable signatures of objects embedded within it.Comment: 15 pages, 13 figures, 2 tables, accepted for publication in the Astrophysical Journa

    The recruitment of knowledge regarding plurality and compound formation during language comprehension

    Get PDF
    Compound formation has been a major focus of research and debate in mental lexicon research. In particular, it has been widely observed that compounds with a regular plural non-head are dispreferred, and a long line of research has examined the nature of this constraint, including which morphological, semantic or phonological properties of the non-head underlie this dispreference. While it is typically assumed that this constraint in fact leads to the barring of a compound analysis to a noun-noun string which would otherwise violate the constraint, its implementation during sentence comprehension has not been thoroughly examined. Using self-paced reading, we demonstrate that knowledge of pluralization and compound formation is immediately utilized in the assignment of structure to noun-noun strings, and that the dispreference for regular plural non-heads in fact leads the parser away from the compound analysis in favor of a more complex grammatical alternative. These results provide new evidence for the online deployment of knowledge regarding pluralization and its interaction with compound formation, and inform our understanding of how morphological information is deployed during, and impacts real-time sentence comprehension

    Bloque de concreto prefabricado incorporando ceniza de bagazo de caña de azúcar, para mejorar su resistencia a compresión, Tarapoto – 2023

    Get PDF
    El objetivo del presente estudio es evaluar las propiedades físicas y mecánicas del bloque de concreto con ceniza de bagazo de la caña de azúcar (CBCA) como sustituto parcial del cemento, a fin de reducir el impacto que tiene este en el medio ambiente. Para ello, se sustituyó la CBCA en cuatro porcentajes: 0% (bloque patrón referencial), 3%, 5% y 8%, evaluando sus propiedades mecánicas (resistencia a la compresión) y físicas (humedad natural, peso unitario y específico, absorción de agua e índice de vacíos). Los resultados obtenidos fueron favorables al incorporar el 3% de CBCA en el bloque de concreto; el bloque patrón tubo un f’c=26.20 kg/cm2 siendo superado por el bloque de concreto con 3% de CBCA con un f’c=26.77 kg/cm2, el bloque patrón costó S/. 339.38 mientras que el bloque de concreto con 3% de CBCA fue de S/. 337.74, resultando el costo por m3 más económico por S/. 1.64
