The research is not concerned with creating a justification for lean manufacturing strategies but rather it evaluates the inadequacies of standard financial reporting methods to accurately reflect operational improvements possible in the key performance measures through the early stages of a lean program.

ProModel simulation software is used in conjunction with Microsoft Excel and Visual Basic to create a simulated repetitive manufacturing environment and production planning and control system. The study examines the …

The Relationship Between Locus Of Control And Nutrition Health Status Among Adult Wic Participants, Damita Jo Zweiback

Dissertations

The purpose of this study is to examine the relationship between locus of control orientation and the nutrition health status of adult WIC participants in Michigan. The locus of control variable is defined as the degree to which an individual perceives reinforcement or outcomes as contingent upon his or her own behavior. It ranges from internal to external. Internal locus of control is the individual's belief that s/he is an actor and can determine one's fate within limits. External locus of control is the person's belief that s/he is controlled by forces outside of one's self (Lefcourt, 1976; Koger, 1999). …

Common Sense Parenting (Csp) Learn At Home Kit: A Clinical Effectiveness Evaluation Of A Commercially Available Video Training Program For Parents, Sean T. Smitham

Dissertations

Much has been made of the gap between psychotherapy research and clinical practice. Most current psychotherapy research is focused on what could be viewed as macro-level efficacy type issues, while practicing clinicians are often most concerned with micro-level effectiveness questions. The current study-an evaluation of a parent training (PT) program provides an example of how scientist-practitioners can contribute meaningfully to psychotherapy research by conducting small scale clinical effectiveness studies. Parent Training (PT) is a well established efficacious treatment approach for child disruptive behaviors and non-compliance. Recent research has also established that self-administered videotape PT programs may also be efficacious. A …

Divine Minds: The Cognitive Foundations Of God And Religion, Todd Tremlin

Dissertations

Understanding how human brains work bears directly on the study of religion. Introducing the new "cognitive science of religion," this dissertation explains how natural mental processes that shape everyday human thought are also responsible for the arising and persistence of religious ideas and for the content and development of religions. The central claim of this work is that understanding the origin and features of god concepts and the religious systems that form around them requires an understanding of the adapted mind. This argument unfolds in two parts. The first explores the cognitive foundations ofsupernatural beings. It discusses in both evolutionary …

The Effects Of Negotiated Written Feedback Within Formative Assessment On Fourth Grade Students' Motivation And Goal Orientations, Craig Alan Waddell

Dissertations

This research was a field-based investigation into the impact of written feedback on students' perceptions, motivation, and academic performance. Seventy-nine fourth grade students, from five elementary classrooms participated in two studies. Study 1 (n=15) was an ABAB-type, reversal design, intended to provide support for a cause-and-effect relationship between feedback scores (i.e., a rubric-based evaluation of teacher's written feedback) and feedback effectiveness (i.e., a survey-based measure of students' views on the value of written feedback). Study 2 (n=64) was a quasi-experimental study intended to demonstrate: a) the relationship between feedback scores and feedback effectiveness, b) an association between feedback effectiveness and …

Effects Of Disability Disclosure And Acknowledgment On Ratings Of Interviewees With Visible Disabilities, Lisa Lynn Roberts

Dissertations

While some authors stress the benefits of disclosing one's disability prior to the interview in order to eliminate interviewer surprise, attention-related research suggests that such disclosure is likely to result in self-focused thinking by the interviewer, reducing the ability to judge performance accurately. Similarly, verbal acknowledgment of a visible disability during an interview has been predicted to reduce interviewer anxiety, yet some authors contend that acknowledgment is a violation of the rules of interviewing and adds to discomfort. The present research addressed the question: What are the effects of an applicant's pre-interview disability disclosure and disability acknowledgment during the interview? …

Pitchfork Bifurcations Of Invariant Manifolds, Jyoti Champanerkar

Dissertations

In a parameter dependent, dynamical system, when the qualitative structure of the solutions changes due to a small change in the parameter, the system is said to have undergone a bifurcation. Bifurcations have been classified on the basis of the topological properties of fixed points and invariant manifolds of dynamical systems. A pitchfork bifurcation in R is said to have occurred when a stable fixed point becomes unstable and two new stable fixed points, separated by the unstable fixed point come into existence.

In this thesis, a pitchfork bifurcation of an (in- 1)-dimensional invariant submani-fold of a dynamical system in …

Network Anomaly Detection Using Management Information Base (Mib) Network Traffic Variables, Jun Li

Dissertations

In this dissertation, a hierarchical, multi-tier, multiple-observation-window, network anomaly detection system (NADS) is introduced, namely, the MIB Anomaly Detection (MAD) system, which is capable of detecting and diagnosing network anomalies (including network faults and Denial of Service computer network attacks) proactively and adaptively. The MAD system utilizes statistical models and neural network classifier to detect network anomalies through monitoring the subtle changes of network traffic patterns. The process of measuring network traffic pattern is achieved by monitoring the Management Information Base (Mifi) II variables, supplied by the Simple Network Management Protocol (SNMP) LI. The MAD system then converted each monitored …

Modeling Contaminant Transport And Fate And Subsequent Impacts On Ecosystems, Ming Fan

Dissertations

Assessing risks associated with the release of metals into the environment and managing remedial activities requires simulation tools that depict speciation and risk with accurate mechanistic models and well-defined transport parameters. Such tools need to address the following processes: (1) aqueous speciation, (2) distribution mechanisms, (3) transport, and (4) ecological risk. The primary objective of this research is to develop a simulation tool that accounts for these processes. Speciation in the aqueous phase can be assessed with geochemical equilibrium models, such as MINEQL+. Furthermore, metal distribution can be addressed mechanistically. Studies with Pb sorption to amorphous aluminum (HAG), iron (HFO), …

The United States Supreme Court And American Individualism, Gary C. Roberts

Dissertations

The United States Supreme Court occupies an unusual, oftentimes paradoxical position within American democracy. On one hand, it is an institution that seemingly lacks democratic legitimacy, and on the other, it is an institution that dutifully gives meaning to the nation's democratic values. The uniqueness and possibly the grandeur of the American Supreme Court is that it has historically been able to successfully combine these two apparently contradictory aspects in such a manner as to expand upon the nation's traditional sense of individualism--the whole notion of an individual's inalienable right to life, liberty, and property.

Using legal case analysis, the …

A Comparative Study Of Interrater Reliability Coefficients Obtained From Different Statistical Procedures Using Monte Carlo Simulation Techniques, Ebrima Nying

Dissertations

Reliability estimation is a key research component within the global area of educational assessment. The literature reports numerous studies using different statistical techniques for estimating reliability of educational measures. However, few have focused on the estimation of interrater reliability of performance assessment (Abedi, Baker, & Herl, 1995). Specifically, this study compared three different methods for estimating interrater reliability to determine if there are differences among these estimates as a function of: sample size, measurement scale, number of raters and the theoretical population reliability (rho). The three methods of estimation were the Intraclass Correlation (ICC(2, k )) (Shrout & Fleiss, 1979), …

From Violence-Prone To Violence-Prepared Organizations Assessing The Role Of Human Resources Management In Preventing Workplace Violence In American City Governments, Saleh Abdel Rahman Ahmed

Dissertations

Violence is a significant occupational hazard in the American workplace. Nearly a thousand employees are murdered on the job each year and workplacehomicide has become the leading cause of death for women and the second for men. From 1993 to 1999, there were an average of 1.7 million nonfatal violent victimizations each year, accounting for 18% of all violent crime. Although government employees accounted for 18% of the U.S. workforce, they made up 37% of workplace violence victims.

A review of literature found no unified definition of workplace violence. Recent scientific research regarding this problem is rare, despite its increasing …

Essays On The Econometrics Of Financial Volatility, Yasemin Bardakci

Dissertations

My dissertation consists of three essays on the econometric analysis of financial volatility.

My first essay is titled "The Runs Test for Volatility Forecastibility: Extensions and Comparisons with Tests for GARCH." Recently, Diebold and Christoffersen (2000) introduced a test for forecastable volatility. In this paper, I compare the size and the power of the runs test and the optimal LM test for GARCH by Monte Carlo simulation. For high frequency returns the LM test has superior power to the runs test. For low frequency returns however, the tests have very similar power. I also propose a switching variance model. For …

The Effects Of Task Structure And Group Target Monetary Incentives On Social Loafing, Nelson R. Eikenhout

Dissertations

Social loafing refers to the decrease in individual performance output that occurs when individuals perform a task in groups in which the output is pooled. Pooled output refers to the performance of all group members added together to get a total group output. Therefore, because all group members contribute to a single group outcome, individual performance output is obscured. This study examined the following questions. First, what are the effects of the method of pooling the output (additive vs. disjunctive) on individuals who work on a concurrent task in small groups? Second, what are the effects of group target based …

The Effects Of Individual And Group Incentives On High Performance, Heather M. Mcgee

Dissertations

The present study examined the performance levels of high performers under equally-divided group monetary incentives, individual monetary incentives, and hourly pay to determine: (a) whether the performance levels of high performers would be higher under individual and group incentive pay systems than under an hourly pay system, (b) whether the performance of high performers would be lower under group incentives than under individual incentives, and (c) whether changes in performance would be due to comparative feedback indicating that the participant is a high performer. Participants were eleven college students who performed a computerized work task that simulated the job of …

Role Of Naming In Stimulus Categorization By Preschool Children, Caio Flavio Miguel

Dissertations

The purpose of the current study was to assess whether children would categorize pictures when taught the relevant listener and speaker behaviors separately. A category-sort test was used to assess emergent conditional relations. Category-sort trials consisted of looking at (Test 1) or tacting/labeling (Test 2) a samplestimulus and selecting the appropriate comparison stimuli. In Experiment 1, 4 children (3- 5 years) were taught to tact pictures of six U.S. state maps as either north or south. An assessment was conducted to determine whether they would (1) correctly categorize or sort when presented with a visual sample and (2) select the …

A Behavioral Account Of Remembering: Precurrent Behavior And Mediation Of Delayed Matching To Sample, David W. Sidener

Dissertations

Although “memory” research and theory often come under the domain of cognitive psychology, these areas may also be seen as being open to radical behavioral interpretations. Delayed matching to sample (DMTS) preparations have often been used to study performance that involves the occurrence of behavior some time after the presentation of a relevant stimulus, or what is typically called short-term memory (STM). The current study involved three experiments that provided evidence for the role of overt behavior in the mediation of DMTS performance in five-year-old children. Experiments 1 and 2 support the assertion that sample-specific, differential mediating behavior (in the …

Electronic Literacy: Teaching Literary Reading Through The Digital Medium, Robert Adams Rozema

Dissertations

Over the last decade, digital technology has become an increasingly important part of education. In the discipline of English language arts, digital technology has been enlisted to teach writing, as the word processor and more recently, the World Wide Web, have provided new tools and new publishing opportunities for student writers. The presence of digital technology is less pronounced, however, in literature instruction in secondary schools. In both theoretical and practical discussions of digital technology and literature, the two mediums have been conceived as radically different. This dissertation argues that the digital medium, and more specifically the World Wide Web, …

“Imagined Communities” In Showcases: The Nationality Rooms Program At The University Of Pittsburgh (1926-1945), Lucia Curta

Dissertations

From the inception of the program in 1926, the Nationality Rooms at the University of Pittsburgh were viewed as apolitical in their iconography. Their purpose was primarily didactic. Designed as classrooms meant for lectures and seminars, they were however ad-hoc museums for the display of symbols of national identity. In many ways, they constitute an excellent illustration in terms of the decorative arts of Benedict Anderson's concept of "imagined communities."

The identity referent of the symbolism attached to the decorative arrangements of these rooms was not that of the ethnic communities in Pittsburgh, for whom the rooms were supposedly designed …

Recipes For Reform: Americanization And Foodways In Chicago Settlement Houses, 1890-1920, Stephanie J. Jass

Dissertations

During the late nineteenth century as tens of thousands of immigrants flooded American cities, public debate among reformers--who tended to be middle-class, white, Anglo-Saxon Protestants--began to center on the best ways to assimilate these foreigners into American society. Although some Americanization groups stressed language and citizenship training, two major reform movements focused on foodways as an important tool of assimilation.

This dissertation examines how both the home economics and settlement house movements attempted to Americanize ethnic food practices. It describes why reformers saw foodways as a viable and meaningful avenue for reform, as well as the varied responses that reformers …

The Interactions Between An Orthodox Christian Worldview And Environmental Attitudes And Beliefs; For The Purpose Of Developing Better Instructional Practice In Support Of Environmental/Ecological Attitudes And Knowledge, Robert S. Keys

Dissertations

Students bring with them to the classroom a wide variety of beliefs and attitudes about the environment and its associated issues. One worldview belief structure prominently discussed in ecological discussions is the worldview of orthodox Christianity. This study uses both quantitative and qualitative measures to analyze the degree to which the orthodox Christian worldview of students influences their environmental attitudes and beliefs. Surveys were conducted with 281 undergraduate pre-service elementary teaching students enrolled in a science methods course to determine the degree to which orthodox Christian worldviews and ecological worldviews interact with one another. From this pool of students, 16 …

Islam And Democracy: An Empirical Examiniation Of Muslims' Political Culture, Moataz Bellah Mohamed Abdel Fattah

Dissertations

This dissertation focuses on the following empirical puzzle: do the attitudes of ordinary educated Muslims stand as an obstacle toward the adoption of democracy? This research question calls for empirical/behavioral methodological tools that bring into focus contemporary Muslims' attitudes rather than ancient jurists' contributions. In other words, the dissertation shifts attention from ancient Islamic texts to contemporary Muslims' mindsets through written and web-bases surveys in 32 Muslim societies.

At the aggregate level, Muslim societies perplex with two types of sub-cultures: the culture of "dictator, but..." and the culture of "democracy-as-a-must." The former is the sub-couture of two groups of Muslims: …

On Similarity Measures For Cluster Analysis, Ahmed Najeeb Khalaf Albatineh

Dissertations

This study discusses the relationship between measures of similarity which quantify the agreement between two clusterings of the same set of data. This study identifies a family [Special characters omitted.] of similarity measures which are of a special form and attain a maximum value of 1 and becomes identical when corrected for chance agreement. In particular, this study proves that the similarity measures of Rand (R), Hubert (H), and Czekanowski (CZ) are identical when corrected for chance agreement. It also proves that the measures of McConnaughey (MC) and Kulczynski (K) are identical when corrected for chance agreement. Moreover, if the …

Deconstructing Fordism: Legacies Of The Ford Sociological Department, Georgios Paris Loizides

Dissertations

Institutional theories of organizations state that organizations reflect society's wider values and norms. Less attention has been placed on the questions of whether and how private interest organizations influence wider societal values and norms. This study examines archival material, as well as published primary and secondary sources, relating to the history of the Ford Motor Company, in particular its Sociological Department, in an effort to assess the company's progressive era project to instill in its workforce a particular set of values and attitudes, which were seen by Ford as healthy, and appropriate. Though we are used to seeing Henry Ford …

Inelastic X-Ray Scattering Studies In Lithium And Metal Ammonia Solutions, Ayman Hasan Said

Dissertations

In this work, inelastic x-ray scattering was used to measure the ionic collective excitations of a metal-ammonia system and the atomic form factor of lithium in a single crystal. For lithium and sodium ammonia systems, the measurements were carried out for different metal concentrations (lithium-ammonia with 2 0 , 16, and 13 mole percent metal [MPM] at T'=240K and sodium-ammonia with 18, 14, and 10 MPM at T=222K). These data were analyzed to determine the acoustic collective excitation dispersion relation and the linewidth. Deviations from the Bohm-Staver model for electron-ion coupling are discussed for the low electronic densities. For the …
