Alcohol Use And Gender Effects On Hiv Risk Behaviors In Cocaine-Using Methadone Patients, Carla J. Rash, Nancy M. Petry

UCHC Articles - Research

Injection drug users engage in behaviors that increase the spread of human immunodeficiency virus (HIV) and other infectious diseases. Although methadone maintenance (MM) is highly effective in decreasing heroin use and the spread of HIV, polydrug use, especially the combined use of cocaine and alcohol, is common in MM patients. Alcohol use is independently associated with HIV risk behaviors, and the effects of alcohol use on risk behaviors may vary by gender. This study evaluated the effects of recent heavy alcohol use and gender with respect to HIV risk behaviors in 118 cocaine-abusing methadone patients. Both lifetime and past month …

Individualized Assessment And Treatment Program For Alcohol Dependence: Results Of An Initial Study To Train Coping Skills, Mark D. Litt, Ronald M. Kadden, Elise Kabela-Cormier

UCHC Articles - Research

Cognitive-behavioral treatments (CBT) are among the most popular interventions offered for alcohol and other substance use disorders, but it is not clear how they achieve their effects. CBT is purported to exert its beneficial effects by altering coping skills, but data supporting coping changes as the mechanism of action are mixed. The purpose of this pilot study was to test a treatment in which coping skills were trained in a highly individualized way, allowing us to determine if such training would result in an effective treatment. Conclusions The IATP approach was more successful than PCBT at training adaptive coping responses …

Control Of Electrochemical And Ferryloxy Formation Kinetics Of Cyt P450s In Polyion Films By Heme Iron Spin State And Secondary Structure, Sadagopan Krishnan, Amila Abeykoon, John B. Schenkman, James F. Rusling

UCHC Articles - Research

Voltammetry of cytochrome P450 (cyt P450) enzymes in ultrathin films with polyions was related for the first time to electronic and secondary structure. Heterogeneous electron transfer (hET) rate constants for reduction of the cyt P450s depended on heme iron spin state, with low spin cyt P450cam giving a value 40-fold larger than high spin human cyt P450 1A2, with mixed spin human P450 cyt 2E1 at an intermediate value. Asymmetric reduction–oxidation peak separations with increasing scan rates were explained by simulations featuring faster oxidation than reduction. Results are consistent with a square scheme in which oxidized and reduced forms of …

Burning Men In Effigy: Lindenwood Ladies Confront Changing Gender Ideals, Julian Barr

Student Scholarship

Lindenwood was founded in 1827 as a women’s college and it took 142 years to break this tradition. In the fall 1968 semester returning students came back and found a big surprise. That year the first men came to campus and changed Lindenwood forever. Periodically men could be found in any given year that were part of the theater program but it wasn’t until 1968 when men were admitted and given a dorm. In 1969 Lindenwood expanded as a coordinate college with Lindenwood I and Lindenwood II and later became a single college, as it is now. This seems like …

Paying Medicare Advantage Plans By A Blend-Based System: Where Are The Gains And Losses?, Brian Biles, Jonah Pozen, Grace Arnold

Health Policy and Management Issue Briefs

Medicare Advantage (MA) plans are now paid $11 billion a year and $150 billion over 10 years more than costs in fee-for-service (FFS) Medicare. In the past two years there have been discussions about reducing MA payments to the level of FFS costs and using the savings to offset the costs of new Federal initiatives such as health care reform. These discussions have included a number of options on the specific new approach to pay plans including: average FFS costs in each county; a blend of local county FFS costs and national FFS average costs; and a regional system based …

How The Conception Of Knowledge Influences Our Educational Practices: Toward A Philosophical Understanding Of Epistemology In Education, James Magrini

Philosophy Scholarship

This paper explores how the conception and valuation of the knowledge within our educational practices determines the planning, writing, and implementation of the curriculum. There is a pressing need for educators to philosophically and systematically understand the relationship between the foundational epistemological beliefs that ground a curriculum and its relationship to forming the notions of competency, pedagogy, and the methods for evaluating and assessing student progress. These issues are not only relevant, but crucial when attempting to justify a particular conception of education, which relates directly to the student's potential for intellectual growth and social development. It may be argued …

Detecting Lag-One Autocorrelation In Interrupted Time Series Experiments With Small Datasets, Clare Riviello, S. Natasha Beretvas

Journal of Modern Applied Statistical Methods

The power and type I error rates of eight indices for lag-one autocorrelation detection were assessed for interrupted time series experiments (ITSEs) with small numbers of data points. Performance of Huitema and McKean’s (2000) z_HM statistic was modified and compared with the z_HM, five information criteria and the Durbin-Watson statistic.

Relationship Between Internal Consistency And Goodness Of Fit Maximum Likelihood Factor Analysis With Varimax Rotation, Gibbs Y. Kanyongo, James B. Schreiber

Journal of Modern Applied Statistical Methods

This study investigates how reliability (internal consistency) affects model-fitting in maximum likelihood exploratory factor analysis (EFA). This was accomplished through an examination of goodness of fit indices between the population and the sample matrices. Monte Carlo simulations were performed to create pseudo-populations with known parameters. Results indicated that the higher the internal consistency the worse the fit. It is postulated that the observations are similar to those from structural equation modeling where a good fit with low correlations can be observed and also the reverse with higher item correlations.

Estimating Model Complexity Of Feed-Forward Neural Networks, Douglas Landsittel

Journal of Modern Applied Statistical Methods

In a previous simulation study, the complexity of neural networks for limited cases of binary and normally-distributed variables based the null distribution of the likelihood ratio statistic and the corresponding chi-square distribution was characterized. This study expands on those results and presents a more general formulation for calculating degrees of freedom.

Level Robust Methods Based On The Least Squares Regression Estimator, Marie Ng, Rand R. Wilcox

Journal of Modern Applied Statistical Methods

Heteroscedastic consistent covariance matrix (HCCM) estimators provide ways for testing hypotheses about regression coefficients under heteroscedasticity. Recent studies have found that methods combining the HCCM-based test statistic with the wild bootstrap consistently perform better than non-bootstrap HCCM-based methods (Davidson & Flachaire, 2008; Flachaire, 2005; Godfrey, 2006). This finding is more closely examined by considering a broader range of situations which were not included in any of the previous studies. In addition, the latest version of HCCM, HC5 (Cribari-Neto, et al., 2007), is evaluated.

Least Error Sample Distribution Function, Vassili F. Pastushenko

Journal of Modern Applied Statistical Methods

Email: The empirical distribution function (ecdf) is unbiased in the usual sense, but shows certain order bias. Pyke suggested discrete ecdf using expectations of order statistics. Piecewise constant optimal ecdf saves 200%/N of sample size N. Results are compared with linear interpolation for U(0, 1), which require up to sixfold shorter samples at the same accuracy.

Closed Form Confidence Intervals For Small Sample Matched Proportions, James F. Reed Iii

Journal of Modern Applied Statistical Methods

The behavior of the Wald-z, Wald-c, Quesenberry-Hurst, Wald-m and Agresti-Min methods was investigated for matched proportions confidence intervals. It was concluded that given the widespread use of the repeated-measure design, pretest-posttest design, matched-pairs design, and cross-over design, the textbook Wald-z method should be abandoned in favor of the Agresti-Min alternative.

Multiple Search Paths And The General-To-Specific Methodology, Paul Turner

Journal of Modern Applied Statistical Methods

Increased interest in computer automation of the general-to-specific methodology has resulted from research by Hoover and Perez (1999) and Krolzig and Hendry (2001). This article presents simulation results for a multiple search path algorithm that has better properties than those generated by a single search path. The most noticeable improvements occur when the data contain unit roots.

Estimation Of The Standardized Mean Difference For Repeated Measures Designs, Lindsey J. Wolff Smith, S. Natasha Beretvas

Journal of Modern Applied Statistical Methods

This simulation study modified the repeated measures mean difference effect size, d⁼_RM , for scenarios with unequal pre- and post-test score variances. Relative parameter and SE bias were calculated for dRM ≠ versus dRM = . Results consistently favored d^≠_RM over d⁼_RM with worse positive parameter and negative SE bias identified for d⁼_RM for increasingly heterogeneous variance conditions.
