Structural Sexism in the United States and Patterns of Women's Alcohol Use in Recent Decades
Alcohol consumption is a leading cause of morbidity and premature mortality. In the United States, consumption remains highly prevalent, and certain subgroups have been increasing alcohol risks in recent decades. Among these are women in the mid-life, who have increased rates of both alcohol consumption (vs. abstention) and binge drinking (i.e., multiple drinks in a setting). Womenâs alcohol use has increased concurrent with social and economic gains. These gains in womenâs social and economic status are indicative of broader declines in structural sexism, a macro-level, systematic source of gender inequality. The objective of this dissertation is to examine the associations between state-level structural sexism (e.g.., social, political, and economic gender inequality) and patterns of womenâs alcohol consumption.
This dissertation is presented in five chapters: first, an introduction; second, a narrative historical review of the relationship between structural sexism in the United States and womenâs health outcomes, with a lens towards understanding the theoretical and epidemiologic sources of conflicting study findings; third, an empirical study of the relationship between state-level structural sexism and both alcohol consumption and binge drinking among women in the mid-life in recent cohorts; fourth, an empirical study examining structural sexism as a source of heterogeneity for relationships between womenâs social positionsânamely, their occupational characteristicsâand both alcohol consumption and binge drinking; fifth, a discussion of findings and implications for future research.
Materials and methods
The narrative literature review drew from empirical studies in public health, criminology, and sociology (N=43 studies). The two empirical aims used longitudinal data from Monitoring the Future (MTF), a national survey examining substance use throughout young adulthood, using data from cohorts who were high school seniors between 1988-2006. For both empirical aims, I measured structural sexism using a factor-analytically derived score based on state-level social and economic indicators of gender inequality, and assessed occasions of alcohol consumption and probability of binge drinking as study outcomes. Both studies used three-level multilevel models to estimate associations between structural sexism and each alcohol outcome. The first empirical aim included a sample of 23,862 women surveyed between 1988-2016, and beyond the marginal association also tested the role of three mediators: depressive symptoms, college completion, and restrictive alcohol norms. The second empirical aim included a sample of 16,571 women in the MTF follow-up surveys between 1989-2016, and examined whether associations among work status, high-status careers, occupational gender composition, and both alcohol outcomes varied across levels of structural sexism using interaction models between occupational characteristics and state structural sexism.
Results
The review identified the divergent theoretical frameworks and measurement invariance as the most pressing threats to reconciling competing findings. In the review I also observed a dearth of empirical studies relating structural sexism to any behavioral health outcomes, including alcohol use. In the first empirical study, I demonstrated that women living in states with lower levels of structural sexism evidenced increases in both occasions of alcohol consumption (RR: 0.974, 95% CI: 0.971, 0.976) and probability of binge drinking (OR: 0.917, 95% CI: 0.909, 0.926); I showed that this relationship was specific to women (i.e., it was less pronounced among men) and that mediators of this relationship included increases in college completion and decreases in restrictive alcohol norms. In the second empirical study, I found that working women evidenced higher frequencies of alcohol consumption and higher probabilities of binge drinking than non-working women, and that these differences were most pronounced among women in low-sexism environments. At the lowest level of structural sexism, employed women reported higher occasions of consumption (2.61, 95% CI 2.57, 2.64) then unemployed women (2.32, 95% CI 2.27, 2.37). I also found that women in high-status occupations reported more occasions of alcohol consumption than those in low-status occupations, but only in low-sexism environments.
Conclusions
Lower levels of structural sexism are related to increases in both alcohol consumption and binge drinking among women. In low-sexism environments, working and belonging to a high-status career increases womenâs alcohol use. Increases in womenâs equality are positive and important social forces, but have conferred new acceptability of alcohol use that has implications for womenâs health
Preparation and characteristics of the sulfonated chitosan derivatives electrodeposited onto 316l stainless steel surface
In order to ameliorate the properties of corrosion resistance and achieve applications in anti-biofouling of 316L stainless steel (SS), a sulfated derivative of chitosan was deposited onto stainless steel surface by an electrochemical method. In detail, chitosan-catechol (CS-CT) was synthesised in the hydrochloric acid solution by the Mannich reaction and then electrodeposited on the surface of the polished 316L stainless steel. The chitosan-catechol deposited SS sample was further modified with maleic anhydride and sulfite. The grafting progress was monitored by FTIR, UV spectrophotometer and X-ray photoelectron spectroscopy. Hydrophilicity and corrosion resistance of modified SS were characterized by water contact angle measurements, Tafel curves and electrochemical impedance spectroscopy. The morphology of the SS surface before and after the modification was investigated by atomic force microscopy and scanning electron microscope. Further, the anti-biofouling performance in terms of the anti-adsorption protein and anti-bacteria effects of all modified SS samples were estimated, and the modified 316L exhibits the capability of lower protein adsorption and improved antibacterial effect.info:eu-repo/semantics/publishedVersio
Police killings of Black people and rates of sexually transmitted infections: A cross-sectional analysis of 75 large US metropolitan areas, 2016
Objectives Emerging literature shows that racialised police brutality, a form of structural racism, significantly affects health and well-being of racial/ethnic minorities in the USA. While public health research suggests that structural racism is a distal determinant of sexually transmitted infections (STIs) among Black people, no studies have empirically linked police violence to STIs. To address this gap, our study measures associations between police killings and rates of STIs among Black residents of US metropolitan statistical areas (MSAs). Methods This cross-sectional ecological analysis assessed associations between the number of Black people killed by police in 2015 and rates of primary and secondary syphilis, gonorrhoea and chlamydia per 100 000 Black residents of all ages in 2016 in 75 large MSAs. Multivariable models controlled for MSA-level demographic and socioeconomic characteristics, police expenditures, violent crime, arrest and incarceration rates, insurance rates and healthcare funding. Results In 2015, the median number of Black people killed by police per MSA was 1.0. In multivariable models, police killings were positively and significantly associated with syphilis and gonorrhoea rates among Black residents. Each additional police killing in 2015 was associated with syphilis rates that were 7.5% higher and gonorrhoea rates that were 4.0% higher in 2016. Conclusions Police killings of Black people may increase MSA-level risk of STI infections among Black residents. If future longitudinal analyses support these findings, efforts to reduce STIs among Black people should include reducing police brutality and addressing mechanisms linking this violence to STIs
Evidence for HIV transmission across key populations: a longitudinal analysis of HIV and AIDS rates among Black people who inject drugs and Black heterosexuals in 84 large U.S. metropolitan areas, 2008â2016
Purpose: To assess cross-population linkages in HIV/AIDS epidemics, we tested the hypothesis that the number of newly diagnosed AIDS cases among Black people who inject drugs (PWID) was positively related to the natural log of the rate of newly diagnosed HIV infections among Black non-PWID heterosexuals in 84 large U.S. metropolitan statistical areas (MSAs) in 2008â2016. Methods: We estimated a multilevel model centering the time-varying continuous exposures at baseline between the independent (Black PWID AIDS rates) and dependent (HIV diagnoses rate among Black heterosexuals) variables. Results: At MSA level, baseline (standardized ÎČ = 0.12) Black PWID AIDS rates and change in these rates over time (standardized ÎČ = 0.11) were positively associated with the log of new HIV diagnoses rates among Black heterosexuals. Thus, MSAs with Black PWID AIDS rates that were 1 standard deviation= higher at baseline also had rates of newly diagnosed HIV infections among Black non-PWID heterosexuals that were 10.3% higher. A 1 standard deviation increase in independent variable over time corresponded to a 7.8% increase in dependent variable. Conclusions: Black PWID AIDS rates may predict HIV rates among non-PWID Black heterosexuals. Effective HIV programming may be predicated, in part, on addressing intertwining of HIV epidemics across populations
Towards Carbon Neutral CO2 Conversion to Hydrocarbons
With fossil fuels still predicted to contribute close to 80â% of the primary energy consumption by 2040, methods to limit further CO2 emissions in the atmosphere are urgently needed to avoid the catastrophic scenarios associated with global warming. In parallel with improvements in energy efficiency and CO2 storage, the conversion of CO2 has emerged as a complementary route with significant potential. In this work we present the direct thermoâcatalytic conversion of CO2 to hydrocarbons using a novel iron nanoparticleâcarbon nanotube (Fe@CNT) catalyst. We adopted a holistic and systematic approach to CO2 conversion by integrating process optimizationâidentifying reaction conditions to maximize conversion and selectivity towards long chain hydrocarbons and/or short olefinsâwith catalyst optimization through the addition of promoters. The result is the production of valuable hydrocarbons in a manner that can approach carbon neutrality under realistic industrial process conditions
Production of Crotonaldehyde from Acetaldol
Optimum operating conditions for the production of crotonaldehyde from acetaldol were investigated and the kinetics of the reaction were determined. The most important operating conditions were found to be the cracking time, the pH value of the reaction mixture, and the initial concentration of acetaldol. The order of the reaction was found to be 1.8 with respect to the acetaldol concentration. The kinetic parameters were determined to be 20.583 (m3/kmol)0.8/min for the frequency factor, and 3416.800 kJ/kmol for the activation energy. Copyright © 1994 Publisher John Wiley & Sons, Ltd
Binary approach to the analysis of prehistoric bison distribution and paleoecology in northern Colorado and southern Wyoming, A
2014 Fall.Includes bibliographical references.Bison exploitation is at the heart of prehistoric hunter-gatherer subsistence on the Great Plains and can reveal robust information regarding patterns of migration, chronology, and variability in paleoclimate. However, despite association with human subsistence practices, bison population and distribution patterns across time and space are unclear. This thesis presents a study of prehistoric bison distribution and population ecology in archaeological and natural contexts in northern Colorado and southern Wyoming. Two methods are used here to reconstruct the diet and distributions of prehistoric bison populations. The first method involves identifying the known distribution of bison in archaeological and natural settings in the study area through an analysis of archival documentation. Cultural chronologies based on archaeological associations have long been valuable in regional research, but can be imprecise and of insufficient resolution for constructing detailed sequences of prehistoric events. Therefore, to expand knowledge of the regional archaeological distribution of bison, this research utilized a total of 272 archaeological sites containing faunal remains. In addition, 291 calibrated radiocarbon dates were used to compile and analyze bison presence and absence through sum probability distributions and statistical analyses. The second method explores the paleoecology of bison through the use of carbon (13C/12C) and nitrogen (15N/14N) stable isotopes analysis of bone collagen from 35 prehistoric bison specimens. Stable isotopes analysis helps to characterize bison distribution and ecology through reconstruction of bison dietary forage and is compared with paleoclimate data in order to identify trends in bison migration and population patterns. This study adds significant chronological information to the regional record of bison presence in northern Colorado and southern Wyoming and helps to correlate bison distribution patterns with the paleoclimate record

The Leo Castelli Gallery in Metro magazine : American approaches to post-abstract figuration in an Italian context
textBetween the years 1960 and 1970, New York gallerist Leo Castelli was closely involved with Milanese editor and publisher Bruno Alfieri's Metro magazine--an international review of contemporary art. By placing his artists in Metro, Castelli inserted them into the world of Italian art criticism and theory. This recontextualization familiarized the American artists of Castelli's gallery to a European audience and positioned them at the end of a succession of modern European styles. Specifically, Castelli's artists, each of whom engaged in a form of pictorial figuration, were seen as ending the dominance of the "pure" abstraction of the French informel style. This thesis uses the archive of correspondence between Bruno Alfieri and Leo Castelli to examine Castelli's contribution to Metro during the 1960s. Departing from this chronology, it also seeks to understand the unique brand of figuration that each of Castelli's artists brought to Metro, given cues from contemporary Italian theory and criticism--particularly that of Gillo Dorfles, who wrote on several of Castelli's artists.Art Histor

Asymptotic autobiography : fairy tales as narrative map in the writing of Zelda Fitzgerald
textWhen a writer, usually a woman, uses fairy tales as a veil through which to narrate a story of her life, I call this practice asymptotic autobiography. In mathematics, the asymptote is a straight line that a curve approaches increasingly closely, but never actually touches. I define âasymptotic autobiographyâ as a term for discussing any personal narrative that deliberately employs fiction in order to tell truth. In this inquiry, I examine the use of fairy tale language in giving voice to women writersâ autobiographical representations, using Zelda Fitzgeraldâs novel and letters as the focus for my analysis. My research and critical analysis will examine how Save Me the Waltz, which Zelda Fitzgerald wrote while she was a psychiatric patient in the Phipps Clinic, uses fairy tales to provide a mapping of the many performances that autobiographical selfhood entails. By experimenting with open-ended fairy tale conventions instead of being limited by clinical truths, and by contextualizing her personal history in the realm of the imaginary, Fitzgerald removes her story from the psychiatric ward and places it safely in legend.
The first three chapters of this dissertation show how, in sequence, the autobiographical self becomes free through the use of fairy tales in three stages: once the autobiographer has worked to separate herself from being bound by illness or clinical reality (Chapter One), she is free to make the decision of which self or selves she wishes to narrate and perform (Chapter Two); only once she has established her sense of self can the autobiographer then locate her plot, her map, and her narrative (Chapter Three). In Chapter Four, I offer an example of asymptotic autobiography in the form of a one-person play script that I wrote and performed about Zelda Fitzgeraldâs life and hospitalization, using as a frame the fairy tale âThe Swan Maiden.â This hybrid essay-performance combines the play script itself with personal writing of my own in which I describe the difficulties I had approaching and performing the rich material of Zeldaâs life.Englis
