Nonparametric Confidence Intervals For The One- And Two-Sample Problems, Xiao-Hua Zhou, Phillip Dinh

UW Biostatistics Working Paper Series

Confidence intervals for the mean of one sample and the difference in means of two independent samples based on the ordinary-t statistic suffer deficiencies when samples come from skewed distributions. In this article, we evaluate several existing techniques and propose new methods to improve coverage accuracy. The methods examined include the ordinary-t, the bootstrap-t, the biased-corrected acceleration (BCa) bootstrap, and three new intervals based on transformation of the t-statistic. Our study shows that our new transformation intervals and the bootstrap-t intervals give best coverage accuracy for a variety of skewed distributions; and that our new transformation intervals have shorter interval …

Medicaid's Disproportionate Share Hospital Program: Complex Structure, Critical Payments, Robert E. Mechanic

This background paper describes the history and political evolution of Medicaid’s disproportionate share hospital (DSH) program and examines DSH as it exists today. It highlights the importance of DSH payments for the viability of safety net hospitals and considers the consequences of states’ creative financing strategies for maximizing federal Medicaid matching funds. Finally, this paper reviews several options for improving the structure and effectiveness of the DSH program.

Estimation Of Treatment Effects In Randomized Trials With Noncompliance And A Dichotomous Outcome , Mark J. Van Der Laan, Alan E. Hubbard, Nicholas P. Jewell

U.C. Berkeley Division of Biostatistics Working Paper Series

We propose a class of estimators of the treatment effect on a dichotomous outcome among the treated subjects within covariate and treatment arm strata in randomized trials with non-compliance. Recent articles by Vansteelandt and Goethebeur (2003) and Robins and Rotnitzky (2004) have presented consistent and asymptotically linear estimators of a causal odds ratio, which rely, beyond correct specification of a model for the causal odds ratio, on a correctly specified model for a potentially high dimensional nuisance parameter. In this article we propose consistent, asymptotically linear and locally efficient estimators of a causal relative risk and a new parameter -- …

Cultural Value Orientations, Attributions, And Breast Cancer Screening Behaviors, Patricia M. Flynn

Loma Linda University Electronic Theses, Dissertations & Projects

Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributional processes, and breast cancer screening behavior among Anglo and Latino women. This study also investigated the influence of acculturation among Latino women in relation to the other study …

Pediatric Obesity: Intervention Outcomes, Kristy Anne Kuehfuss

Loma Linda University Electronic Theses, Dissertations & Projects

Childhood obesity is a national epidemic with serious medical and psychological implications. Almost one-fourth of children in the United States are overweight. Children do not typically grow out of obesity and without intervention the majority of overweight children become overweight adults. Further, childhood obesity results in numerous chronic medical conditions. Thus, the prevention and treatment of childhood obesity are paramount to the avoidance of resultant physical and psychological risk factors. Loma Linda University’s Growing Fit Program seeks to serve the critical and urgent needs of the ever-increasing population of obese children with a multi-disciplinary approach to pediatric weight management. Evaluating …

Psychological Factors Associated With Anticipatory Nausea And Vomiting, Melinda L. Nielsen

Loma Linda University Electronic Theses, Dissertations & Projects

Many cancer patients experience adverse chemotherapy-related side effects. The present study examined the relationships among disease variables (i.e. stage of cancer, type of breast cancer), medical treatment variables (i.e. toxicity of chemotherapy regimen, strength of antiemetic treatment), psychological variables (i.e. health locus of control, anxiety sensitivity, desire for control, coping strategies), and anticipatory nausea and vomiting in women with breast cancer. One hundred women with breast cancer completed the Multidimensional Health Locus of Control Scale - Form C, the Anxiety Sensitivity Index, the Krantz Health Opinion Survey, the Coping Inventory for Stressful Situations, and the Morrow Assessment of Nausea and …

A Report From The Forum Session "Implementing The New Medicare Drug Benefit: Challenges And Opportunities For States", Judith D. Moore

National Health Policy Forum

The National Health Policy Forum convened a meeting on July 22, 2004 to discuss state-based challenges associated with implementing the Medicare Prescription Drug, Improvement, and Modernization Act (MMA). The meeting brought together an extremely insightful and experienced group of current and former state officials and other experts to discuss key issues. In keeping with its tradition of promoting a frank, off-the-record exchange on health policy issues, NHPF does not normally prepare written summaries or reports of meetings. However, because this meeting provided vivid illustrations of the importance of state-federal collaboration for the successful implementation of the new Medicare drug benefit, …

How Much Weight Is Too Much For Manual Lifting : Determining A Weight Limit Guideline For Team-Effort Lifting Tasks, Piyush G. Chapla

Theses

Manual material handling is the primary cause of musculoskeletal injuries, which includes injuries related to lower back, at the workplaces in the U.S. Of all the manual material handling tasks, lifting has been the leading contributor to lower back injuries. These injuries may be induced by several risk factors associated with lifting tasks, weight of the object being lifted being one of them.

Weight limit guidelines have been developed by various groups recommending the weights that workers can lift safely without sustaining injuries. However, these guidelines are aimed to serve individual lifting tasks. Even though team lifting is a common …

Estimation Of Direct And Indirect Causal Effects In Longitudinal Studies, Mark J. Van Der Laan, Maya L. Petersen

U.C. Berkeley Division of Biostatistics Working Paper Series

The causal effect of a treatment on an outcome is generally mediated by several intermediate variables. Estimation of the component of the causal effect of a treatment that is mediated by a given intermediate variable (the indirect effect of the treatment), and the component that is not mediated by that intermediate variable (the direct effect of the treatment) is often relevant to mechanistic understanding and to the design of clinical and public health interventions. Under the assumption of no-unmeasured confounders, Robins & Greenland (1992) and Pearl (2000), develop two identifiability results for direct and indirect causal effects. They define an …

Determination Of The Efficacy Of Two Building Decontamination Strategies By Surface Sampling With Culture And Quantitative Pcr Analysis, Mark P. Buttner, Patrica Cruz, Linda Stetzenbach, Amy Klima-Comba

Environmental & Global Health Faculty Research

The efficacy of currently available decontamination strategies for the treatment of indoor furnishings contaminated with bioterrorism agents is poorly understood. Efficacy testing of decontamination products in a controlled environment is needed to ensure that effective methods are used to decontaminate domestic and workplace settings. An experimental room supplied with materials used in office furnishings (i.e., wood laminate, painted metal, and vinyl tile) was used with controlled dry aerosol releases of endospores of Bacillus atrophaeus (“Bacillus subtilis subsp. niger,” also referred to as BG), a Bacillus anthracis surrogate. Studies were performed using two test products, a foam decontaminant and chlorine dioxide …

CRVAW Faculty Journal Articles

Objectives: Social support for abused women may reduce the impact of abuse on mental health, yet few studies have addressed this issue. We wish to determine associations between intimate partner violence (IPV) and mental health outcomes and to assess the protective role of abuse disclosure and support on mental health among abused women.

Methods: A cross-sectional survey was conducted of 1152 women, ages 18–65, recruited from family practice clinics from 1997 through 1999. They were screened for IPV during a brief in-clinic interview, and physical and mental health status was assessed in a follow-up interview.

Results: IPV, defined as sexual, …

Defining Accelerometer Thresholds For Activity Intensities In Adolescent Girls, Margarita S. Treuth, Kathryn H. Schmitz, Diane J. Catellier, Robert G. Mcmurray, David M. Murray, Maria João C. A. Almeida, Scott Going, James E. Norman, Russell R. Pate

Faculty Publications

Purpose - To derive a regression equation that estimates metabolic equivalent (MET) from accelerometer counts, and to define thresholds of accelerometer counts that can be used to delineate sedentary, light, moderate, and vigorous activity.

Methods - Seventy-four healthy 8th grade girls, age 13-14 yr, were recruited from urban areas of Baltimore, MD, Minneapolis/St. Paul, MN, and Columbia, SC, to participate in the study. Accelerometer and oxygen consumption (VO₂) data for 10 activities that varied in intensity from sedentary (e.g., TV watching) to vigorous (e.g., running) were collected. While performing these activities, the girls wore two accelerometers, a heart …

Multiple Testing Methods For Chip-Chip High Density Oligonucleotide Array Data, Sunduz Keles, Mark J. Van Der Laan, Sandrine Dudoit, Simon E. Cawley

U.C. Berkeley Division of Biostatistics Working Paper Series

Cawley et al. (2004) have recently mapped the locations of binding sites for three transcription factors along human chromosomes 21 and 22 using ChIP-Chip experiments. ChIP-Chip experiments are a new approach to the genome-wide identification of transcription factor binding sites and consist of chromatin (Ch) immunoprecipitation (IP) of transcription factor-bound genomic DNA followed by high density oligonucleotide hybridization (Chip) of the IP-enriched DNA. We investigate the ChIP-Chip data structure and propose methods for inferring the location of transcription factor binding sites from these data. The proposed methods involve testing for each probe whether it is part of a bound sequence …

Combining Predictors For Classification Using The Area Under The Roc Curve, Margaret S. Pepe, Tianxi Cai, Zheng Zhang

UW Biostatistics Working Paper Series

We compare simple logistic regression with an alternative robust procedure for constructing linear predictors to be used for the two state classification task. Theoritical advantages of the robust procedure over logistic regression are: (i) although it assumes a generalized linear model for the dichotomous outcome variable, it does not require specification of the link function; (ii) it accommodates case-control designs even when the model is not logistic; and (iii) it yields sensible results even when the generalized linear model assumption fails to hold. Surprisingly, we find that the linear predictor derived from the logistic regression likelihood is very robust in …

Effects Of A Tailored Follow-Up Intervention On Health Behaviors, Beliefs, And Attitudes, Alissa D. Jacobs, Alice S. Ammerman, Susan T. Ennett, Marci K. Campbell, Katherine W. Tawney, Semra Aytur, Stephen W. Marshall, Julie C. Will, Wayne D. Rosamond

Health Management & Policy

Background: The high rates of relapse that tend to occur after short-term behavioral interventions indicate the need for maintenance programs that promote long-term adherence to new behavior patterns. Computer-tailored health messages that are mailed to participants or given in brief telephone calls offer an innovative and time-efficient alternative to ongoing face-to-face contact with healthcare providers.

Methods: Following a 1-year behavior change program, 22 North Carolina health departments were randomly assigned to a follow-up intervention or control condition. Data were collected from 1999 to 2001 by telephone-administered surveys at preintervention and postintervention for 511 low-income, midlife adult women enrolled …

The Association Of Blood Type On The Five Factors Of Personality In Chinese Adolescents, Kunher Wu

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to identify the number of personality factors in Chinese adolescents using the Chinese Revised NEO Personality Inventory (NEO-PI-R) and to determine whether blood type is associated with personality. It is widely accepted by psychologists that the five-factor model can provide an adequate representation of adult personality dimensions, but there is less agreement on the number of factors observable in adolescence. A total of 3,396 11^th graders from the city of Kaohsiung, Taiwan completed the Chinese NEO-PI-R. Principle component analysis with varimax rotation showed five factors of personality in these Taiwanese adolescents, which clearly …

An Ergonomic Assessment Of The Airline Baggage Handler, Stephen P. Salomon

Theses

A material or baggage handler is responsible for loading and unloading baggage and materials from inbound/outbound aircraft flights and transferring the materials to and from the baggage holding and sorting areas and back to the passengers or output source. Baggage handlers work in all types of inclement weather, all over the airport, and in-and-around the aircraft. The baggage handler's job entails repeated lifting pulling, pushing, squatting, twisting, kneeling, and stretching of the arms and back, which makes the baggage handler's job one of the more challenging material handling jobs to ergonomically assess and make corrections for. The aim of the …

Osha Laboratory Safety Standard 29 Cfr 1910.1450 And Achieving Compliance In The Microelectronic Laboratory, Danielle M. Digironimo

Theses

This thesis is a practical application of occupational exposures to hazardous substances in a microelectronics laboratory. The Occupational Safety and Health Administration (OSHA) standard for the safety in laboratories is (29 CFR 1910.1450). The application is a demonstration of the implementation of the standard in a university setting. Hazards that exist in laboratory settings are very complex and the task of providing a safe workplace can become increasingly complicated. A laboratory can and does impose different health and safety concerns that a standard industrial workplace setting might not have. The need for a laboratory safety standard program to be implemented …

Predicting The Use Of Personal Respiratory Protection Among Workers In Swine Confinement Buildings, M. Susan Jones

The study was designed to answer four research questions: 1). What is the validity and reliability of the Personal Respiratory Protection Survey (PRPS)? 2). How frequently do workers in SCBs wear PRP? 3). How do demographics, occupational histories, and self-reported respiratory health histories influence the use of PRP in SCBs? and 4). What are the relationships of the constructs (benefits, barriers, susceptibility, severity, norms) to the use of PRP by workers in SCBs? …

On Corrected Score Approach For Proportional Hazards Model With Covariate Measurement Error, Xiao Song, Yijian Huang

UW Biostatistics Working Paper Series

In the presence of covariate measurement error with the proportional hazards model, several functional modeling methods have been proposed. These include the conditional score estimator (Tsiatis and Davidian, 2001), the parametric correction estimator (Nakamura, 1992) and the nonparametric correction estimator (Huang and Wang, 2000, 2003) in the order of weaker assumptions on the error. Although they are all consistent, each suffers from potential difficulties with small samples and substantial measurement error. In this article, upon noting that the conditional score and parametric correction estimators are asymptotically equivalent in the case of normal error, we investigate their relative finite sample performance …

Religion And Crime: A Study Of Inmates In State And Federal Prisons In The United States., Dhanalakshmi Thirumalai

Electronic Theses and Dissertations

Persistent high levels of crime in this country have provided support for the need for public programs that help in reducing crime rates through effective interventions. Spirituality and religion are considered to play a major part in determining an individual's attitude towards committing a crime. This study analyzed if inmates in State and Federal prisons in the US are involved in prison religious activities and personal prayers in order to determine if criminality (measured by offense type) of inmates affects their participation in religious activities. Based on logistic regression analysis, gender, race, and marital status of inmates were found to …

Investigation And Calculation Of Dose Coefficients For Radionuclides Produced In A Spallation Neutron Source Using The Ensdf And Nubase Nuclear Databases, Yayun Song

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dose coefficients are useful for risk assessment during the design and siting of accelerator-driven nuclear facilities including the Spallation Neutron Source. There are seventy-two radionuclides with half-lives equal to or greater than one minute that will be produced by the spallation of a mercury target for which no published dose coefficients exist. Out of these seventy-two, twenty-four currently have conflicting published nuclear data in the Evaluated Nuclear Structure Data Files (ENSDF) and the NUBASE data files. In this research these twenty-four radionuclides have been studied. Because of missing ENSDF records, internal and external dose coefficients were determined for only six …

Evaluating Markers For Selecting A Patient's Treatment, Xiao Song, Margaret S. Pepe

UW Biostatistics Working Paper Series

Selecting the best treatment for a patient's disease may be facilitated by evaluating clinical characteristics or biomarker measurements at diagnosis. We consider how to evaluate the potential of such measurements to impact on treatment selection algorithms. For example, magnetic resonance neurographic imaging is potentially useful for deciding whether a patient should be treated surgically for carpal tunnel syndrome or if he/she should receive less invasive conservative therapy. We propose a graphical display, the selection impact (SI) curve, that shows the population response rate as a function of treatment selection criteria based on the marker. The curve can be useful for …

The Influence Of Social Status On Token Women Leaders’ Expectations About Leading Male-Dominated Groups, Theodore W. Mcdonald, Loren L. Toussaint, Jennifer A. Schweiger

Public and Population Health Faculty Publications and Presentations

Prior research has shown that women report mostly negative expectations about being a gender-token in male-dominated work groups. We speculate that this is partially caused by the socially-ascribed status devaluation of women. In the present study we investigated the degree to which elevated social status may lessen negative expectations of gender-token women assigned to leadership positions. Sixty-three undergraduate women participated in one of three tokenism conditions: 1) nontoken, 2) gender-token, and 3) high-status gender-token. In all conditions participants were led to believe that they would be leading a group of men in a decision-making exercise. Leader expectations were then assessed. …

An Assessment Of Hiv/Aids Risk In Higher Education Students In Yerevan, Armenia, Talin Babikian, Mary Catherin Freier, Gary L. Hopkins, Ralph Diclemente, Duane C. Mcbride, Matt Riggs

Faculty Publications

Armenia's current sociopolitical and economic instability and the alarming HIV incidence rates in neighboring countries amplify its risk for a national epidemic. The goals of this study were to assess HIV/AIDS knowledge and risk behaviors among higher education students in Yerevan. Knowledge of HIV transmission through sexual intercourse was markedly higher than that on intravenous transmission and prevailing myths; however, HIV/AIDS knowledge was not related to risk behaviors. Tobacco and alcohol prevalence was relatively high. Students reported risky sexual behaviors, including inconsistent condom use, casual sex, and multiple partners. In addition to descriptive statistics delineating gender differences across the target …

Pain As A Secondary Condition Experienced Byrural Medicaid Beneficiaries With Disabilities, Craig Ravesloot Ph.D., University Of Montana Rural Institute
