DIFFERENCES BETWEEN ALCOHOLIC DRUNK DRIVERS WHO ABSTAIN, CONTROL THEIR DRINKING OR RELAPSE AFTER TREATMENT.

The present study used univariate and multivariate data analyses to investigate the combination of variables that could be used to differentiate between and predict drinking habits of male alcoholics after treatment. Alcoholic subjects were Abstainers (N = 60), Controlled drinkers (N = 60) and Relapsed drinkers (N = 60). Forty variables were assessed including measures of demographics and social stability, problem drinking, treatment characteristics, and psychopathology. The ANOVA revealed that alcoholics who relapse after treatment had lower incomes, higher alcohol consumption, and higher Michigan Alcoholism Screening Test and Behavior Impairment Index scores than the controlled drinkers. Relapsed drinkers had more frequent and longer previous inpatient treatment and attended more A.A. meetings than the controlled drinkers. The relapsed drinkers also had less ongoing treatment and poorer attendance in treatment than the abstainers. The relapsed drinkers had significantly higher scores than the abstainers or controlled drinkers on the Frequency (F), Hypochondriasis (Hs), Depression (D), Psychopathic deviate (Pd), Paranoia (Pa), Psychasthenia (Pt), Schizophrenia (Sc), Social Introversion (Si), and Anxiety (A) scales of the MMPI. A stepwise multiple regression technique that maximized the multiple correlation coefficient (R(\u272)) produced a 28 variable model which accounted for 25 percent of the variance in drinking behavior. Discriminant analysis differentiated between the three groups such that the relapsed drinkers were very high on psychopathology (Function 1) and near the mid range of problem drinking (Function 2). The abstainers were low on psychopathology and moderately high on problem drinking while the controlled drinkers were low on psychopathology and moderately low on problem drinking. Classification coefficients were generated for use in predicting or classifying drinking behavior of new subjects. Unfortunately, the discriminant analysis revealed that, although better than at a chance level (33 percent), the model was able to correctly classify only 63 percent of the abstainers, 60 percent of the controlled drinkers, and 65 percent of the relapsed drinkers. The implications and problems of the present study are discussed.Dept. of Psychology. Paper copy at Leddy Library: Theses & Major Papers - Basement, West Bldg. / Call Number: Thesis1985 .S658.

Soliton cellular automata for the affine general linear Lie superalgebra

The box-ball system (BBS) is a cellular automaton that is an ultradiscrete analogue of the Korteweg--de Vries equation, a non-linear PDE used to model water waves. In 2001, Hikami and Inoue generalised the BBS to the general linear Lie superalgebra $\mathfrak{gl}(m|n)$. We further generalise the Hikami--Inoue BBS to column tableaux using the Kirillov--Reshetikhin crystals for $\hat{\mathfrak{gl}}{(m|n)}$ devised by Kwon and Okado (arXiv:1804.05456), where we find similar solitonic behaviour under certain conditions.Comment: 53 pages, 0 figure

Frozen reaction fronts in steady flows: a burning-invariant-manifold perspective

The dynamics of fronts, such as chemical reaction fronts, propagating in two-dimensional fluid flows can be remarkably rich and varied. For time-invariant flows, the front dynamics may simplify, settling in to a steady state in which the reacted domain is static, and the front appears "frozen". Our central result is that these frozen fronts in the two-dimensional fluid are composed of segments of burning invariant manifolds---invariant manifolds of front-element dynamics in $xy\theta$-space, where $\theta$ is the front orientation. Burning invariant manifolds (BIMs) have been identified previously as important local barriers to front propagation in fluid flows. The relevance of BIMs for frozen fronts rests in their ability, under appropriate conditions, to form global barriers, separating reacted domains from nonreacted domains for all time. The second main result of this paper is an understanding of bifurcations that lead from a nonfrozen state to a frozen state, as well as bifurcations that change the topological structure of the frozen front. Though the primary results of this study apply to general fluid flows, our analysis focuses on a chain of vortices in a channel flow with an imposed wind. For this system, we present both experimental and numerical studies that support the theoretical analysis developed here.Comment: 21 pages, 30 figure

How Perioperative Clinics at Duke University Can be Utilized to Narrow the Gap of Health Disparities in African American Populations: A Narrative Review

An issue often explored in today’s social climate is racial inequalities in our healthcare system and the strong negative outcomes it has on minority patient populations. This is a result of a combination of social factors not limited to, healthcare resources available to these patients, implicit bias by providers, discrimination of patient population, and a system of healthcare perpetuating continued injustices. Research has shown the operating room is no exception, but recent advances in perioperative medicine may be a key to eliminating barriers to equitable healthcare for patients of color. The purpose of this narrative review is to bring awareness to the utility of using perioperative clinics to bring equitable health care to patients of color who are historically at an increased risk of post-operative complications. Innovation of these multidisciplinary clinics is not only a huge stepping-stone in the field of anesthesia, but also an avenue to narrow the gap in health disparities amongst patients of color. Perioperative clinics utilize objective data to assess a patient’s readiness for surgery and minimize physician bias while boosting access to healthcare for disadvantaged patient populations

On the interaction of Jupiter's Great Red Spot and zonal jet streams

In this paper, Jupiter's Great Red Spot (GRS) is used to determine properties of the Jovian atmosphere that cannot otherwise be found. These properties include the potential vorticity of the GRS and its neighboring jet streams, the shear imposed on the GRS by the jet streams, and the vertical entropy gradient (i.e., Rossby deformation radius). The cloud cover of the GRS, which is often used to define the GRS's area and aspect ratio, is found to differ significantly from the region of the GRS's potential vorticity anomaly. The westward-going jet stream to the north of the GRS and the eastward-going jet stream to its south are each found to have a large potential vorticity ``jump''. The jumps have opposite sign and as a consequence of their interaction with the GRS, the shear imposed on the GRS is reduced. The east-west to north-south aspect ratio of the GRS's potential vorticity anomaly depends on the ratio of the imposed shear to the strength of the anomaly. The aspect ratio is found to be $\approx$2:1, but without the opposing jumps it would be much greater. The GRS's high-speed collar and quiescent interior require that the potential vorticity in the interior be approximately half that in the collar. No other persistent geophysical vortex has a significant minimum of potential vorticity in its interior and laboratory vortices with such a minimum are unstable.Comment: Manuscript accepted to Journal of the Atmospheric Sciences, March 2007. v2: minor stylistic changes (after journal proof reading

Nosology, epidemiology and pathogenesis of bipolar disorder: Recent approaches

Bipolar disorder is a highly prevalent, chronic and deteriorating mental illness that requires medical, psychological and social care for life. Realizing that bipolar disorder is more common than initially thought, the associated disability and the heterogeneity in their clinical presentation, has strengthened the research on this topic. Recent advances in the field of nosology, epidemiology and pathogenesis have begun to unravel some of the complexity of this disorder and have had a marked influence on the changes in the way they are beginning to diagnose a broad spectrum of bipolar disorders according to the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM 5)
