    Many compulsive and hypersexualized behaviors, including pornography use, have been associated with negative emotional, neurological, and psychosocial problems in a subset of users. Research showed that the constructs of shame, shame-proneness, and attachment may be related to the use of pornography as well as the theory of addiction. Shame-proneness is a construct that is consistently and positively associated with a variety of internalizing symptoms including depression, social, and generalized anxiety as well as a linked to an assortment of externalizing and risky behaviors such as anger, substance use, and criminal offending. Research suggested that higher levels of religiosity have a strong relationship to the moral disapproval of the use of pornography based on individual religious beliefs. This study examined the correlation between religiosity and sexual shame based on earlier research, which hypothesized that moral disapproval would mediate the relationship between religiosity and sexual shame. This research also hypothesized that shame-proneness would moderate the relationships between religiosity and moral disapproval, moral disapproval, and sexual shame, and finally the relationship between religiosity and sexual shame. The results showed that consistent with earlier research; moral disapproval mediated the relationship between religiosity and sexual shame. The study found that shame-proneness was a direct predictor of sexual shame however it did not moderate direct or indirect effects on the proposed theoretical relationships

    Loss of Free Fatty Acid Receptor 2 leads to impaired islet mass and beta cell survival

    The regulation of pancreatic β cell mass is a critical factor to help maintain normoglycemia during insulin resistance. Nutrient-sensing G protein-coupled receptors (GPCR) contribute to aspects of β cell function, including regulation of β cell mass. Nutrients such as free fatty acids (FFAs) contribute to precise regulation of β cell mass by signaling through cognate GPCRs, and considerable evidence suggests that circulating FFAs promote β cell expansion by direct and indirect mechanisms. Free Fatty Acid Receptor 2 (FFA2) is a β cell-expressed GPCR that is activated by short chain fatty acids, particularly acetate. Recent studies of FFA2 suggest that it may act as a regulator of β cell function. Here, we set out to explore what role FFA2 may play in regulation of β cell mass. Interestingly, Ffar2(-/-) mice exhibit diminished β cell mass at birth and throughout adulthood, and increased β cell death at adolescent time points, suggesting a role for FFA2 in establishment and maintenance of β cell mass. Additionally, activation of FFA2 with Gαq/11-biased agonists substantially increased β cell proliferation in in vitro and ex vivo proliferation assays. Collectively, these data suggest that FFA2 may be a novel therapeutic target to stimulate β cell growth and proliferation

RAG acknowledges the funding from the PLATO CNES grant.With recent advances in modelling stars using high-precision asteroseismology, the systematic effects associated with our assumptions of stellar helium abundance (Y) and the mixing-length theory parameter (αMLT) are becoming more important. We apply a new method to improve the inference of stellar parameters for a sample of Kepler dwarfs and subgiants across a narrow mass range (⁠0.8<M<1.2M⊙). In this method, we include a statistical treatment of Y and the αMLT. We develop a hierarchical Bayesian model to encode information about the distribution of Y and αMLT in the population, fitting a linear helium enrichment law including an intrinsic spread around this relation and normal distribution in αMLT. We test various levels of pooling parameters, with and without solar data as a calibrator. When including the Sun as a star, we find the gradient for the enrichment law, ΔY/ΔZ=1.05+0.28−0.25 and the mean αMLT in the population, μα=1.90+0.10−0.09, μα=1.90+0.10−0.09⁠. While accounting for the uncertainty in Y and αMLT, we are still able to report statistical uncertainties of 2.5 per cent in mass, 1.2 per cent in radius, and 12 per cent in age. Our method can also be applied to larger samples that will lead to improved constraints on both the population level inference and the star-by-star fundamental parameters.Publisher PDFPeer reviewe

    PBjam: A Python package for automating asteroseismology of solar-like oscillators

    Full text link
    Asteroseismology is an exceptional tool for studying stars by using the properties of observed modes of oscillation. So far the process of performing an asteroseismic analysis of a star has remained somewhat esoteric and inaccessible to non-experts. In this software paper we describe PBjam, an open-source Python package for analyzing the frequency spectra of solar-like oscillators in a simple but principled and automated way. The aim of PBjam is to provide a set of easy-to-use tools to extract information about the radial and quadrupole oscillations in stars that oscillate like the Sun, which may then be used to infer bulk properties such as stellar mass, radius and age or even structure. Asteroseismology and its data analysis methods are becoming increasingly important as space-based photometric observatories are producing a wealth of new data, allowing asteroseismology to be applied in a wide range of contexts such as exoplanet, stellar structure and evolution, and Galactic population studies.Comment: 12 Pages, 4 figures.
