A Bayesian Meta-Analysis Using The Gibbs Sampler, Shannon Marie Fair

UNF Graduate Theses and Dissertations

A meta-analysis is the combination of results from several similar studies, conducted by different scientists, in order to arrive at a single, overall conclusion. Unlike common experimental procedures, the data used in a meta-analysis happen to be the descriptive statistics from the distinct individual studies.

In this thesis, we will consider two regression studies performed by two scientists. These studies have one common dependent variable, Y, and one or more independent common variables, X. A regression of Y on X with other independent variables is carried out on both studies. We will estimate the regression coefficients of X …

A Java Implementation Of A Portable Desktop Manager, Scott J. Griswold

UNF Graduate Theses and Dissertations

Computers equipped with a Graphical User Interface (GUI) and connected to the Internet are common in both the business and educational communities. These computers, using a web browser, easily share programs written in the Java programming language that are able to execute on a variety of heterogeneous machines.

While programs written in many languages will not execute unmodified on different computing platforms because of portability restrictions, Java has overcome these limitations and provides a platform independent language. However, every programming language is limited, and no language provides all the features required for every program. Therefore, creation of any portable program …

Courting Serendipity: Constructivist Theory And Classroom Practice, Marilyn Duckworth Jensen

UNF Graduate Theses and Dissertations

This dissertation is a cross-case study and analysis of four teachers in a school involved in two reform initiatives which promote constructivist approaches to teaching and learning. The study describes the teachers' understandings of the learning theory and their interpretations of it in their classroom practice. The study found that three of the four teachers were practicing in ways consistent with constructivism while one was not because her need for control took precedence. The study found that although teachers are very aware of their students as individuals with different ways of learning and constructing an understanding, they are not much …

The Effects Of Systematically Fading Reinforcement While Maintaining Skills, Jodi Suzanne Bronson

Dissertations and Theses @ UNI

A review of the literature describing treatment programs for young children with autism revealed two distinctly different strategies. One, the Lovaas approach (Lovaas, 1987), focused on an intense, one-on-one discrete trial training format implemented for approximately 40 hours per week. A prescribed curriculum targeted at social and communication skills is incorporated. The second program, TEACCH, emphasized an individualized curriculum selected after a careful assessment process to determine a person's strengths and limitations. Goals and objectives were subsequently implemented in highly structured special education classrooms where the focus was on antecedent control and the use of visually mediated strategies. Interviews with …

The War At Home: Prisoner Of War Camps In Iowa During World War Ii, Julie K. Heintz

Dissertations and Theses @ UNI

Two base camps, along with their branch camps, located in the state of Iowa will provide the focus for this study. The camps in Iowa, located near the towns of Algona and Clarinda, provide an example of two camps that met or exceeded the criteria set by the Geneva Convention of 1929. The creation and administration of the camps raises three questions which constitute the body of this thesis. The first deals with the founding, administration and operation of the camps. Secondly, the study investigates the daily life of the camp inmates. Finally the third question examines how townspeople and …

Portrait Of Success: A Situational Analysis Case Study Of Students Challenged By Attention-Deficit/Hyperactivity Disorder, Sandra Hundley Zimmermann

Harold L. Hodgkinson Award for Outstanding Dissertation

This study examined factors that encouraged and supported academic success for students diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). Students with ADHD are often not academically successful and do not graduate from high school, due in large measure to ADHD symptoms of (a) impulsive and reckless behaviors, (b) alienation from significant others including peers, and (c) disorganization. Students in this study overcame symptoms of ADHD and were academically successful.

The situational analysis case study design for this research utilized both qualitative methods (interview, observation, and record review) and quantitative instrumentation. Five students with ADHD comprised the case study sample. Data from student, …

Inactivation Of Soybean Peroxidase During Sodium Azide Oxidation: A Comparative Study, Mohamed Yehia Zakaria Aboul Eish

Dissertations and Theses @ UNI

Azide ion is a mechanism-based inactivator of a number of peroxidases. However, there are often variations in the manner in which inactivation occurs. Soybean Peroxidase (SBP) is found in the plant's seed coat. Unlike many other peroxidases, a single enzyme rather than several isozymes are produced thus making more simple the purification and characterization of the enzyme. In this research it was shown that, as with other peroxidases, SBP is inactivated by azide during turnover. During azide oxidation SBP forms a ferrous-NO intermediate. In this respect, SBP is similar to the lignin peroxidases from Phanerochaete chrysosporium which also form ferrous-NO …

Time-Resolved Studies Of Ultracold Ionizing Collisions, Scott D. Bergeson, C. Orzel, S. Kulin, S. L. Rolston

Faculty Publications

Using 40 ns laser pulses, we probe the real-time dynamics of ultracold ionizing collisions in metastable xenon. We time resolve both shielding and enhancement effects, and observe the production of Xe2^+ molecular ions through associative ionization. We estimate the rate of molecule formation in excited-state collisions, and directly measure the role of both flux enhancement and excited state survival in the collisional enhancement process. Conceptually simple theoretical models are used to predict the dynamics of the collisional shielding.

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages, Craig H. Hart, David A. Nelson, Clyde C. Robinson, Susanne Frost Olson, Mary Kay Mcneilly-Choque

Faculty Publications

Maternal and paternal parenting styles and marital interactions linked in childhood aggressive behavior as described in Western psychological literature were measured in an ethnic Russian sample of 207 families of nursery-school-age children. Results corroborated and extended findings from Western samples. Maternal and paternal coercion, lack of responsiveness, and psychological control (for mothers only) were significantly correlated with children's overt aggression with peers. Less responsiveness (for mothers and fathers) and maternal coercion positively correlated with relational aggression. Some of these associations differed for boys versus girls. Marital conflict was also linked to more overt and relational aggression for boys. When entered …

Family Generativity And Generative Counseling: Helping Families Keep Faith With The Next Generation, David C. Dollahite, Brent D. Slife, Alan J. Hawkins

Faculty Publications

Counselors who are concerned with strengthening and healing relationships between generations can draw on the concept of generativity to assist them. This chapter invites counselors to grant a more prominent place for generativity in clinical work with families by (a) presenting the concept of family generativity as a logical extension of the generativity concept and (b) presenting some initial ideas on the new approach to clinical work designed to help families develop and sustain family generativity, which we call generative counseling. Generative counseling is illustrated by use of a clinical example, which is introduced briefly in a subsequent section …

A Mathematical Model For Fibroblast And Collagen Orientation, J. C. Dallon, J. A. Sherratt

Faculty Publications

Due to the increasing importance of the extracellular matrix in many biological problems, in this paper we develop a model for fibroblast and collagen orientation with the ultimate objective of understanding how fibroblasts form and remodel the extracellular matrix, in particular its collagen component. The model uses integro-differential equations to describe the interaction between the cells and fibers at a point in space with various orientations. The equations are studied both analytically and numerically to discover different types of solutions and their behavior. In particular we examine solutions where all the fibroblasts and collagen have discrete orientations, a localized continuum …

The Star-Spangled Banner Forever Be Furled: The Mormon Exodus As Liberty, Richard Bennett

Faculty Publications

You wanted to know what we waited to move for, wrote Sidney Tanner, an early Mormon pioneer, to his family in the East. "It was to go to a land of freedom where we could enjoy the peace of society and our liberty. We did not want to live in a country where there was no peace, no liberty and its citizens [were] not allowed their rights." So much has been written about the Mormon Trail that one wonders if there is anything of consequence to be said. Surely all the prominent details are well known. And were it not …

Modeling Soot Derived From Pulverized Coal, Alexander L. Brown, Thomas H. Fletcher

Faculty Publications

A semiempirical model has been developed for predicting coal-derived soot. The main feature of the model is a transport equation for soot mass fraction. Tar prediction options include either an empirical or a transport equation approach, which directly impacts the source term for soot formation. Also, the number of soot particles per unit mass of gas may be calculated using either a transport equation or an assumed average. Kinetics are based on Arrhenius rates taken from published measurements. Radiative properties are calculated as a function of averaged optical constants, predicted gas temperatures, predicted gas densities, and the soot mass fractions. …

Approximations Of Open Quotient And Speed Quotient From Glottal Airflow And Egg Waveforms: Effects Of Measurement Criteria And Sound Pressure Level, Christopher Dromey, Christine M. Sapienza, Elaine T. Stathopoulos

Faculty Publications

Summary: Noninvasive measures of vocal fold activity are useful for describing normal and disordered voice production. Measures of open and speed quotient from glottal airflow and electroglottographic (EGG) waveforms have been used to describe timing events associated with vocal fold vibration. To date, there has been little consistency in the measurement criteria used to calculate quotient values. In this study, criteria of 20% and 50% were applied to the AC amplitude of glottal airflow and inverted EGG waveforms for measurement of open quotient. Criteria of 20%, 50%, and 80%, and a midslope criterion that segmented the waveform between 20% and …

Object-Oriented Programming And Parallelism, Atanas Radenski

Mathematics, Physics, and Computer Science Faculty Articles and Research

Initially, object-orientation and parallelism originated and developed as separate and relatively independent areas. During the last decade, however, more and more researchers were attracted by the benefits from a potential marriage of the two powerful paradigms. Numerous research projects and an increasing number of practical applications were aimed at different forms of amalgamation of parallelism with object-orientation. It has been realized that parallelism is a inherently needed enhancement for the traditional object-oriented programming (OOP) paradigm, and that object orientation can add significant flexibility to the parallel programming paradigm.

Commercial Codification As Negotiation, David Frisch

Law Faculty Publications

Part I of this Article endeavors to put the sales law in perspective by emphasizing its role in the broader system of commercial law. Then, in Part II we focus on a particular example (the buyer's right to recover goods upon the seller's insolvency) to support our general observation that the revision reflects a fatal insensitivity to the need for article 2 to fit with other bodies of commercial codification. Part III demonstrates the revi~ion's failure to come to terms with the role of context and makes the argument that the drafters' shortsightedness is evidenced by the manner in which …

A Comparative Study Of The Motivations And Academic Self-Concept Of Midlife Male Graduate Students With Those Of Midlife Female, Early Adulthood Male, And Early Adulthood Female Graduate Students, Scott Brewer Clift

UNF Graduate Theses and Dissertations

This study was designed to compare midlife male graduate students with midlife female, early adulthood male, and early adulthood female graduate students in terms of their motivations for returning to higher education and their academic self-concept as returning students. Data were gathered, using Boshiers's Education Participation Scale (1995) and Drummond's Academic Self-Concept Scale (1984), from graduate students at a comprehensive, urban, southeastern, public university of approximately 10,000 students. The 426 graduate student participants were enrolled in three colleges (Business, Education, and Health) at the university.

Three Types Of Gamma-Ray Bursts, Soma Mukherjee, Eric D. Feigelson, Gutti Jogesh Babu, Flonn Murtagh, Chris Fralev, Adrian Raftery

Physics & Astronomy Faculty Publications

A multivariate analysis of gamma-ray burst (GRB) bulk properties is presented to discriminate between distinct classes of GRBs. Several variables representing burst duration, fluence, and spectral hardness are considered. Two multivariate clustering procedures are used on a sample of 797 bursts from the Third BATSE Catalog, a nonparametric average linkage hierarchical agglomerative clustering procedure validated with Wilks' Λ* and other multivariate analysis of variance tests and a parametric maximum likelihood model-based clustering procedure assuming multinormal populations calculated with the Expectation-Maximization algorithm and validated with the Bayesian Information Criterion. The two methods yield very similar results. The BATSE GRB population consists …

Searching For Periodic Sources With Ligo, Patrick R. Brady, Teviet Creighton, Curt Cutler, Bernard F. Schutz

Physics & Astronomy Faculty Publications

We investigate the computational requirements for all-sky, all-frequency searches for gravitational waves from spinning neutron stars, using archived data from interferometric gravitational wave detectors such as LIGO. These sources are expected to be weak, so the optimal strategy involves coherent accumulaton of signal-to-noise using Fourier transforms of long stretches of data (months to years). Earth-motion-induced Doppler shifts, and intrinsic pulsar spindown, will reduce the narrow-band signal-to-noise by spreading power across many frequency bins; therefore, it is necessary to correct for these effects before performing the Fourier transform. The corrections can be implemented by a parametrized model, in which one does …

A Data Analysis Approach For Detecting Gravitational Waves From Psr 0437-4715, Soumya Mohanty, I. S. Heng, David Blair, S. Dhurandhar, M. Tovar, E. Ivanov

Physics & Astronomy Faculty Publications

A search for gravitational waves from the millisecond pulsar PSR 0437-4715 has been initiated using the bar detector NIOBE which is located at the University of Western Australia. We present a detailed report on the data analysis algorithm, called phase plane rotation, which will be used in this search. A discussion of the actual implementation of the algorithm is presented. The data analysis algorithm mentioned above has the advantage that it requires minimal changes to the already-existing data acquisition facility of NIOBE but, at the same time, it is as efficient as optimal filtering in detecting a signal. This …

Critical Casimir Forces Between Spherical Particles In Fluids, Andreas Hanke, F. Schlesener, E. Eisenriegler, S. Dietrich

Physics & Astronomy Faculty Publications

Long-ranged correlations in a fluid close to its critical point Tc cause distinct forces between immersed colloidal particles and the container walls. We calculate such a force and its temperature dependence for the generic case of a spherical particle located at a distance D from a planar wall and find that the force attains a maximum at a temperature Tmax(D) above Tc, which facilitates quantitative experimental tests. The corresponding effective pair interaction between the colloidal particles themselves, potentially leading to aggregation, is also discussed.
