Disparities in Healthcare Utilization Among Adults with Obesity in the United States,Findings from the NHIS: 2006–2015

Population Research and Policy Review - Few studies of disparities consider logistical hurdles faced by adults with obesity in obtaining needed healthcare. This study compared adults with obesity...     

Estimation of tail parameters under type i censoring

This paper is a continuation of previous work concerning the estimation of tail-parameters under Type II censoring (Weissman 1978). The same estimation problem is considered here, this truip under Type I censoring. A sample of size n is censored below aE a given level x₀it is assumed that che underlying distriibution .function (df)belogs to the domain of attraction of a known extreme-value distribution and that K - K(x_o) , the number of observed values, remains finite as on - ∞ . We offer here estimators, which are asymptotically maximum likelihood estimators (MLE's), for quantiles associated with the tail of F such as location and scale parameters, quantiles and F(x) itself (for x in the tail). The results are applied to two illustrative examples.     

On Francis Galton's Difference Problem

Francis Galton proposed to split the money available for the first two prizes in a competition according to some ratio X, depending on the marks of the three best competitors, but invariant under change of location or scale of the marks. Assuming normality, Galton found that EX is about .75 and empirically he observed that X is nearly uniformly distributed between and 1. Our main purpose is to show that Galton was indeed right for a wide class of underlying distributions. As the number of competitors tends to ∞, the ratio X tends (in distribution) to a uniform random variable.     

Statistical Modelling of Brain Morphological Measures Within Family Pedigrees

Large, family-based imaging studies can provide a better understanding of the interactions of environmental and genetic influences on brain structure and function. The interpretation of imaging data from large family studies, however, has been hindered by the paucity of well-developed statistical tools for that permit the analysis of complex imaging data together with behavioral and clinical data. In this paper, we propose to use two methods for these analyses. First, a variance components model along with score statistics is used to test linear hypotheses of unknown parameters, such as the associations of brain measures (e.g., cortical and subcortical surfaces) with their potential genetic determinants. Second, we develop a test procedure based on a resampling method to assess simultaneously the statistical significance of linear hypotheses across the entire brain. The value of these methods lies in their computational simplicity and in their applicability to a wide range of imaging data. Simulation studies show that our test procedure can accurately control the family-wise error rate. We apply our methods to the detection of statistical significance of gender-by-age interactions and of the effects of genetic variation on the thickness of the cerebral cortex in a family study of major depressive disorder.     

Adolescent Externalizing Problems: Contributions of Community Crime Exposure and Neural Function During Emotion Introspection in Mexican‐Origin Youth

Models of the etiology of adolescent antisocial behavior suggest that externalizing problems may reflect a susceptibility to crime exposure and a diminished capacity for emotion introspection. In this study, adolescents of Mexican origin completed a neuroimaging task that involved rating their subjective feelings of sadness in response to emotional facial expressions or a nonemotional aspect of each face. At lower levels of neural activity during sadness introspection in posterior cingulate and left temporoparietal junction, and in left amygdala, brain regions involved in mentalizing and emotion, respectively, a stronger positive association between community crime exposure and externalizing problems was found. The specification of emotion introspection as a psychological process showing neural variation may help inform targeted interventions to positively affect adolescent behavior.     

Marital Outcomes and Consideration of Divorce Among Orthodox Jews After Signing a Religious Prenuptial Agreement to Facilitate Future Divorce

This study examined marital satisfaction, marital adjustment, and consideration of divorce among Orthodox Jews in North America (N = 2,652). These marital outcomes were compared for individuals who signed or did not sign a religious prenuptial agreement that facilitates a woman’s future ability to receive a religious divorce from her husband. Results indicated a higher level of marital satisfaction among those who signed the religious prenuptial agreement, and no significant difference in marital adjustment or tendency to consider divorce between groups of individuals who signed or did not sign the religious prenuptial agreement.     

Repronormativity and the Reproduction of the Nation-State: The State and Sexuality Collide

ABSTRACT

This article seeks to explain the consistent margins between popular support for same-sex marriage and same-sex adoption/parenting. I posit that the paradigm of repronormativity explains these differences, in permitting only “legitimate,” state-sanctioned, heteronormative reproduction. Through three case studies—Poland's strict abortion policies, France's law against lesbians utilizing artificial reproduction technologies, and Sweden's history of sterilizing trans individuals—I will demonstrate how not only does repronormativity select and enforce an inside/outside, in-group(s)/out-group(s) binary and legitimize only certain reproduction, it also tethers female sexuality to reproduction and creates an inevitability of reproduction.
