Robust Residuals And Diagnostics In Autoregressive Time Series, Kirk W. Anderson

Dissertations

One of the goals of model diagnostics is outlier detection. In particular, we would like to use the residuals, appropriately standardized, to “flag” outliers. Hopefully, our (robust) procedure has yielded a fit that resists undue influence by outlying points, while simultaneously drawing attention to these interesting points via residual analysis. In this study we consider several different methods of standardizing the residuals resulting from autoregression. A large sample approximation for the variance of rank-based first order autoregressive time series residuals is developed. This provides studentized residuals, specific to the time series model and estimation procedure. Simulation studies are presented that …

New Statitstical Methods For The Estimation Of The Mean And Standard Deviation From Normally Distributed Censored Samples, Abou El-Makarim Abd El-Alim Aboueissa

Dissertations

The main objective of this dissertation is to estimate the mean /x and standard deviation cr of a normal population from left-censored samples. We have developed new methods for calculating estimates for the mean and standard deviation of a normal population from left-censored samples. Some of these methods based on traditional estimating procedures. A new method of obtaining the Cohen maximum likelihood estimates for fx and cr without the aid of an auxiliary table will be introduced. This new method will be used to extend Cohen table of estimating the Cohen A-parameter that is required for calculating the maximum likelihood …

The Strategic Uses Of Gender In Household Negotiations: Women Workers On Mexico’S Northern Border, Leslie C. Gates

Sociology Faculty Scholarship

The study illustrates the potential of the ‘doing gender’ perspective to explain why employment helps women win some negotiations at home but not others. Eighteen in-depth interviews with women maquiladora workers in Mexico suggest that employment may help women gain new rights and extend the limits of respect accorded them by male companions and parents. Women were more successful when they used negotiating strategies that conformed to their gender identity, such as making offers, than when they used negotiating strategies that challenged traditional gender norms, such as withdrawing services or making threats.

The Emergence Of Mini Uavs For Military Applications, Timothy Coffey, John A. Montgomery

Defense Horizons

The successes of the unmanned aerial vehicle (UAV) in Afghanistan most likely will accelerate the introduction of UAVs into the military force structure. What emerged in Afghanistan was a tiered observation-detection-targeting system consisting of spacecraft, the Global Hawk UAV, the Predator UAV, and often a spotter on the ground. However, in complex terrain, as in Afghanistan, and in urban situations, airborne assets may be needed much closer to the ground. A low-altitude tier of UAVs—mini UAVs—could serve such a purpose.

This paper provides a basic understanding of the aerodynamic scaling of mini UAVs and a sense of how their capabilities …

Historical Changes In Mid-Water Stands Of Common Reed In The Winnebago Pool Lakes, Wisconsin, Anthony O. Gabriel, Leo R. Bodensteiner

All Faculty Scholarship for the College of the Sciences

Despite the tolerance of common reed grass to environmental extremes, mid-water stands in the Winnebago pool lakes of central Wisconsin appear to be diminishing. Formerly occupying shoreline locations, water level manipulations subsequent to dam construction beginning in the 1850's have isolated reed stands off shore. These stands have persisted but casual observations indicate that stand size has been declining. To address this perception we obtained an approximately decadal series of aerial photographs dating back to 1937 for four stands in Lake Poygan. Annual records were available for 1986–94. Using image analysis software, we determined shape and size metrics. Changes in …

Chiefly Politics In The First Reactions In Rakiraki To The May 2000 Coup In Fiji, Stephen C. Leavitt

Pacific Studies

This essay describes the rationale behind local leaders' scramble to respond to unfolding reactions to the coup in Fiji. Once word spread across the countryside that there had been a takeover of Parliament, people felt an immediate sense that the country was undergoing "another coup." This perception created a need to assimilate the events in terms of prevailing political orientations. In Rakiraki, the Tui Navitilevu made a widely publicized pronouncement of support that provoked a hurried attempt to contain reactions from other high-status figures in the area. The incident brought out into the open the usually submerged conflicts over legitimate …

Foreigners At Home: Discourses Of Difference, Fiji Indians And The Looting Of May 19, Susanna Trnka

Pacific Studies

This essay focuses on Fiji Indians' reactions to the property destruction and ethnic violence that followed the 19 May 2000 coup. In particular, it explores why, in the first few weeks following the coup, Indo-Fijians despaired over the looting of downtown shops, rather than over other acts of seemingly more direct anti-Indian violence, such as the burning of Indo-Fijian homes and physical attacks against Indo-Fijian men and women. I analyze how Fiji's Sanatan Hindus discursively posited Indians, on the one hand, as central to the development of Fiji as a "modern," capitalist nation, and Fijians, on the other, as detrimental …

Development Of Water-Based Ink System For Braille Printing, Saurabh Varma

Masters Theses

The most commonly used system of writing by and for blind persons is called Braille, named after its French inventor, Louis Braille (1809-1952). Braille is comprised of a rectangular six-dot cell on its end, with up to 63 possible combinations using one or more of the six dots. Braille is the only reliable method of literacy for blind persons, because it enables them to read and write by touch¹.

Currently, Braille is printed by special embossers that serve as a printing press. These embossers create Braille output when it is attached appropriately to computers. The speed of these …

Specifying The Psychomotor Domain Of The Construct Of Nursing Competence, Joni L. Jones

Dissertations

The measurement of an individual's predicted performance in his/her field is a requirement of many professions. The NCLEX-RN® is the measurement tool used to determine whether or not new graduates of registered nursing programs are competent to enter the profession. Although there are three domains of learning in nursing (cognitive, affective, and psychomotor) the only domain tested for licensure is the cognitive. Many factors contribute to the lack of testing in the psychomotor area. One of the major impediments is that the entry-level psychomotor domain for registered nursing has yet to be defined. The purpose of this study was to …

A Comparison Of One-To-One And Small Group Instruction For Young Children With Autism: Focus On Effective Teaching And Behavior Management, Kathy Marie Bertsch

Dissertations

Over the past two decades, research has focused on identifying successful instructional methods and appropriate programming for young children with autism. Much of this early research focused on the effectiveness of intensive one-to-one behavioral programs. Support for intensive one-to-one instruction for children with autism began a long-term debate over the effectiveness, efficiency and appropriateness of one-to-one instructional strategies for young children with autism. In response, researchers and educators began considering and studying small group instruction, a less restrictive alternative to intensive one-to-one instruction. While support is mounting for the use of small group instructional strategies, there continues to be limited …

Co-Occurring Disorders And Selective Substance Use In Females Ages 10 To 25 Diagnosed With Attention Deficit Hyperactivity Disorder, Nancy A. Clinton

Dissertations

The paucity o f research on females diagnosed with attention deficit hyperactivity disorder (ADHD) precipitated this exploratory investigation into co-occurring disorders and selective substance use in females (n = 70), ranging in age between 10 and 25, diagnosed with ADHD and substance use disorder (SUD). Data extracted from archived substance abuse treatment center records were tested via chi-square analyses to determine proportional differences between frequencies in predetermined co-occurring disorder groups (disruptive behavior disorders, moodanxiety disorders, and learning disorders) and predetermined substance groups (stimulant, depressant, and cannabis) for the total ADHD cohort and for specific diagnoses (inattentive, hyperactive-impulsive, combined, and with …

The Cultural Script Of Special Needs Adoption, George Grant, Jr.

Dissertations

The purpose of the study was to examine special needs adoption from the perspective of the adoptive parents. Using the general guidelines of grounded theory, the study analyzed secondary data from a post-adoption program providing services to families who adopted special needs children. The data revealed that adoptive parents function under a cultural script of special needs adoption. The cultural script influences how families view themselves, the environment around them and how they decide to function as adoptive families. The study explains the cultural script, ways that professionals working in adoption can use that cultural script to support adoptive families …

The Effects Of Group Size On Incentive Effectiveness: A Meta-Analysis, Angelica C. Grindle

Dissertations

A meta-analysis was conducted to examine the effects of group size on incentive effectiveness using data obtained from incentive systems implemented in 13 companies. Other predictor variables included the organizational level targeted for improvement, long/short-term profitability type, company number, and length of exposure to the incentive system. The main dependent variable was the monthly score for each measure of performance. Three types of meaningful comparisons were defined for these data: (1) Between-Group - Within-Company comparisons in which a performance measure was in place in two or more units of an organization; (2) Between-Group - Across-Company comparisons in which a performance …

A Study Of The Leadership Preparedness Of U.S. Public University Chief Business Officers, Daniel J. Hurley

Dissertations

Despite the enormous role that Chief Business Officers (CBOs) play in administering the business and financial affairs of American public universities, little research has been conducted on their leadership preparedness. The primary objectives of this study were to assess the self-perceived preparedness of U.S. public university CBOs at the time they assumed their first position in the role, and to determine if specific factors could be associated with their overall preparedness.

With support from the National Association of College and University Business Officers, a survey was developed and mailed to the entire population of CBOs at four-year public universities in …

On Rank-Based Considerations For Generalized Linear Models And Generalized Estimating Equation Models, Diana R. Cucos

Dissertations

This study discusses rank-based robust methods for estimation of parameters and hypotheses testing in the generalized linear models (GLM) and generalized estimating equations (GEE) setting. The robust estimates are obtained by minimizing a Wilcoxon drop in dispersion function for linear or nonlinear regression models. In addition, diagnostic tools for outliers and influential observations are being developed. These models are generalizations of linear and nonlinear models. They allow for both nonlinear mean functions and heteroscedasticity of their random errors. This makes them quite useful in practice. Rank-based inference has been developed for linear models over the last thirty years. This inference …

Teaching My Son To Be A Father: The Plight Of Unmarried Adolescent African American Fathers, Michael George Till

Dissertations

A quantitative research design was utilized to examine and understand the perceptions of fatherhood and manhood held by unmarried African American adolescent fathers. In face-to-face 60-90 minute interviews using a semistructured interview guide developed by the researcher, participants were asked open-ended questions to provide these young men with a voice and an opportunity to express their needs, support, neglect, understanding, and perception of how society views them and its impact on the functioning of the family unit. Using purposeful sampling, 10 unmarried African American adolescent fathers, located in the southwestern area of Michigan, were interviewed for data collection.

Interviews were …

The Effectiveness Of Behavioral Activation Group Therapy: Treating Comorbid Depression On A Specialized Inpatient Posttraumatic Stress Disorder Unit For Combat Veterans, Theodore P. Wright

Dissertations

The comorbidity of depression and PTSD has been shown to be relatively prevalent. Researchers have found a 70% lifetime prevalence o f comorbid PTSD and depression among combat veterans. This study examined the effectiveness of a behavioral activation (BA) group treatment when administered to combat veterans with comorbid depression and PTSD in the residential treatment program at the Battle Creek Veteran Affairs Medical Center. Forty-five veterans participated in the study. Twenty-four veterans participated in a BA treatment group while in the treatment program. Twenty-one veterans attended the treatment program, but did not participate in the BA treatment group and served …

Modeling The Economic Costs Of A Terrorist Threat To A Large-Venue Public Facility, Gregory C. Ashley

Student Work

Insurance companies will pay out an estimated $50 billion in claims as a result of the September 11, 2001 terrorist attacks. The enormous consequences of the attacks to both the local and national economy surprised many and have raised concerns about the cost of such events. Predicting the occurrence and economic cost of terrorist attacks is fundamentally different than predicting the occurrence and economic cost of natural disasters. The cost of natural disasters is more predictable and often can be accurately estimated using historical data. Even losses from typical kinds of crime such as burglary show predictable patterns. Both the …

After Turning Points: Evidence Of The Adoption Of Middle School Reforms In The United States 1987-2000., Nancy Barnes Mansberger

Dissertations

The purpose of this study was to explore the adoption by U.S. middle schools of key practices recommended by the 1989 Turning Points report. Three questions were examined: (1) To what extent have the organizational practices identified by research to impact the development of "small learning communities" been adopted by U.S. middle schools? (2) To what extent do the instructional practices of U.S. middle school teachers reflect developmentally responsive or traditional/bureaucratic methods?, and (3) Do the instructional practices of U.S. middle school teachers differ between those who teach in schools with developmentally responsive organizational practices and those who teach in …

A Teller’S Tale: Joining The Circle -- A Discussion Of Process In The Writing Of A Novel For Young Adults, Susan A. Butler

Critical and Creative Thinking Capstones Collection

In this thesis, I reflect on the writing of fiction for young adults against the backdrop of autobiography. Context is provided by the accompanying opening chapters of a novel for young adults—The Defectives of Ulibar— and excerpts from a journal written during the writing process. Aspects of the creative engagement—open brainstorming, focusing, rewriting—are anchored in the specific locations—a country road, a cabin in the woods, an indoor study—in which the processes occur. In the course of this endeavor, I learn that the writing of fiction, and the reflecting on the writing of fiction, are not after all so different. It …
