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 …

Social Support Protects Against The Negative Effects Of Partner Violence On Mental Health, Ann L. Coker, Paige H. Smith, Martie P. Thompson, Robert E. Mckeown, Lesa Bethea, Keith E. Davis

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, …

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 purpose of this study was to identify the variables that influence the frequency of personal respiratory protection (PRP) use by workers in swine confinement buildings (SCBs). 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 …

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 …

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 …

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 …

Patient Handling Ergonomics, Paul Reichert

Theses

The incidence of musculoskeletal injuries among healthcare workers has been well documented in the medical and ergonomic literature. The epidemiological evidence demonstrates high injury rate among nurses, nurse's aides, therapists and other medical workers who frequently handle patients. The biomechanical research has shown large compressive forces developed in the lumbar spine performing various patient handling transfers that exceed the National Institute of Occupational Safety and Health's recommended guideline. One of the most strenuous patient handling tasks is transferring the patient from bed to the chair and vice versa.

One of the objectives of this thesis is to design and conduct …

Economic Efficiency And Consumer Choice Theory In Nutritional Labeling, Michael Mccann

Law Faculty Scholarship

As more Americans consume fast food each year, more Americans are contracting serious diseases related to obesity. Considering that obesity ranks second behind tobacco use as the largest contributor to mortality rates in the United States, and also that it gives rise to greater publicly funded health care expenses than does tobacco, this phenomenon begs the obvious question: To what extent does the growing consumption of fast food contribute to the obesity epidemic and the incidence of disease? If the answer indicates a meaningful contribution, a natural follow-up question then emerges: In a sensible legal system, what instruments would best …

Anthrax In A Highly Endemic Area: Survey Of Knowledge, Attitudes And Beliefs Among Haitian Livestock Owners And Follow-Up Public Health Practice, Katie Steneroden

International Journal of Global Health and Health Disparities

Anthrax, a zoonotic disease with worldwide distribution, is endemic and enzootic in Haiti. Hyper-endemic areas exist and regional outbreaks occur sporadically throughout the country. The number of cases of human cutaneous anthrax reported in a rural area of central Haiti has increased in the last several years. A cross-sectional questionnaire was developed to ascertain livestock owners' knowledge of anthrax and analyzed for potential risk factors and intervention strategies. Results of this survey indicate that a lack of knowledge of the signs, symptoms and transmission of anthrax may be contributing to an increase in human cases. Survey results have been reported …

Socioeconomic Status And Domestic Violence, Disa K. V. Lubker

International Journal of Global Health and Health Disparities

Domestic violence is pandemic and affects women and families all over the world. It involves the "systematic use of violence and abuse to gain power over and to control a partner of ex-partner (DVIP)." Forms of domestic violence include any physical or sexual contact, aggression or violence that is unwanted and may take the form of threats, harassment, verbal abuse, hitting, kicking, etc. (DVIP). It is estimated that 20 to 50 percent of the world's female population will be victims of domestic violence (Feminist Majority), and in the United States, it is estimated that at some point in their lives, …
