Teachers Perceptions Of Implementing M-Learning Using Pedagogical Approaches, James Albert Barnes

Electronic Theses and Dissertations Archive

Mobile learning (m-learning) has begun its transition from focusing on technology devices to pedagogical approaches that guide the design, development, and implementation of teaching and learning. The trends in the literature have identified pedagogical approaches, professional development and instructional practices that have improved academic achievement with teachers abilities and perceptions as a contributing factor. However, a gap remains about the degree to which teachers effectively integrate and implement m-learning to make a significant impact on teaching and learning. To address this gap, this research was a causal comparative study examining two schools perceptions of implementing m-learning after receiving differing types …

Multi-Period Transportation Network Investment Decision-Making Using Link Ranking And An Econometric Framework, Khademul Haque

Electronic Theses and Dissertations Archive

Prospective transportation infrastructure projects take numerous years of planning before they are scheduled for construction. Moreover, limited funds are forcing national, regional and local governments to carefully prioritize their investments. Therefore, reliable quantitative tools are needed to help decision-makers choose their investments so that the allocation of available resources is optimized. Prioritization of projects over a multi-period planning horizon is a difficult task given a limited budget and an exhaustive set of possible combinations of when each project will be scheduled for construction. Although multi-period network investment is studied in the literature, its application by public agencies is limited because …

Electronic Theses and Dissertations Archive

The overall goal of this dissertation was to examine the adaptivenss of eight emotion regulation strategies for Chinese middle and high school students. The adaptiveness was evaluated by using an intrapersonal approach that focused on individual students in Study 1 and by using an interpersonal approach that focused on same-sex best friend dyads in Study 2. By using an intrapersonal approach, Study 1 found that students chose to use developing competencies, redirecting attention, expressive suppression, and seeking social support more often than the other four strategies. Among the eight emotion regulation strategies, developing competencies was the most adaptive and venting …

Cyclic Performance Improvement Of Existing Steel Semi-Rigid Connections Using Post-Tensioning, Sepehr Movaghati

Electronic Theses and Dissertations Archive

A practical retrofitting method for enhancing the inelastic performance of existing semi-rigid steel connections is introduced and verified in this study. The method entails adding high-strength steel strands parallel to the beam, passing them through the column, and anchoring and post-tensioning them properly. To verify the proposed retrofitting system, firstly, a series of semi-rigid bolted connections was experimentally tested under monotonic and cyclic loadings. Then, the post-tensioning system was applied on the connections with the same geometry, and the cyclic responses were studied under different post-tensioning parameters. Following the recommended setup explained in this study, a locally post-tensioned (PT) structural …

Regression Models For Analyzing Clustered Multinomial And Continuous Outcomes Under The Assumption Of Exchangeability, Peter Ogutu Ngutu

Electronic Theses and Dissertations Archive

We derive an expression for the joint distribution of exchangeable multinomial randomvariables and continous random variables for the purpose of analyzing clusteredmultinomial and continous data. In the past such clustered discrete and continous datacould be analyzed with the use of quasi-likelihood procedures and generalized estimatingequations to estimate marginal mean response parameters. Recently, the idea ofexchangeability has been introduced to handle such data but research has focusedprimarily on analysis of clustered binary and continous outcomes. In applications to areassuch as developmental toxicity studies, where discrete and contionus measures arerecorded on each fetus, the discrete data may not necessarily be binary. For …

Generating Diverse And Meaningful Captions: Unsupervised Specificity Optimization For Image Captioning, Annika Lindh, Robert J. Ross, Abhijit Mahalunkar, Giancarlo Salton, John D. Kelleher

Conference papers

Image Captioning is a task that requires models to acquire a multi-modal understanding of the world and to express this understanding in natural language text. While the state-of-the-art for this task has rapidly improved in terms of n-gram metrics, these models tend to output the same generic captions for similar images. In this work, we address this limitation and train a model that generates more diverse and specific captions through an unsupervised training approach that incorporates a learning signal from an Image Retrieval model. We summarize previous results and improve the state-of-the-art on caption diversity and novelty.

We make our …

On The Structure Of Dense Graphs, And Other Extremal Problems, Richard Snyder

Electronic Theses and Dissertations Archive

Extremal combinatorics is an area of mathematics populated by problems that are easy to state, yet often difficult to resolve. The typical question in this field is the following: What is the maximum or minimum size of a collection of finite objects (e.g., graphs, finite families of sets) subject to some set of constraints? Despite its apparent simplicity, this question has led to a rather rich body of work. This dissertation consists of several new results in this field.The first two chapters concern structural results for dense graphs, thus justifying the first part of my title. In the first chapter, …

Attaining Scientific Literacy Through A Rhetoric Of Science Composition Pedagogy, Stephen C. Smith

Electronic Theses and Dissertations Archive

For the past sixty years, acquiring scientific literacy has proven to be a daunting task in education, especially for undergraduate nonscience majors. Although some education scholars have recognized the importance and use of arguments to teach science, these pedagogical practices often are aimed at primary school children rather than college students or involve reporting science experiments rather than actually studying or constructing arguments about issues related to science.However, in this dissertation, I contend that educators often neglect a more available tool that not only examines arguments concerning scientific issues but also demonstrates the very heart of scientific literacy: critical thinking. …

Statistical Analysis Of Seismicity Catalog Of Alaska: The Mysteries Of The Timeseries, Shima Azizzadehroodpish

Electronic Theses and Dissertations Archive

Abstract:This dissertation presents the results of applying three independent statistical techniques on the seismic catalog of Alaska and Aleutian subduction zone. I perform Visibility Graph Analysis and Multifractal Detrended Fluctuation Analysis respectively on the seismic catalogs of several defined seismogenic zones in surface and depth. Forecasting earthquake hazard is based on the assumption that the Gutenberg-Richter relation represents the size distribution of future earthquakes and we show that the series produced by these methods have properties with close correlation with the b-value of the Gutenberg-Richter law. Visibility graph analysis basically maps a time series into the networks of nodes and …

A Simple Model For Elastic-Plastic Contact Of Granular Geomaterials, Jian Wang, Qimin Li, Changwei Yang, Yidan Huang, Caizhi Zhou

Materials Science and Engineering Faculty Research & Creative Works

We propose a simple elastic-plastic contact model by considering the interaction of two spheres in the normal direction, for use in discrete element method (DEM) simulations of geomaterials. This model has been developed by using the finite element method (FEM) and nonlinear fitting methods, in the form of power-law relation of the dimensionless normal force and displacement. Only four parameters are needed for each loading-unloading contact process between two spheres, which are relevant to material properties evaluated by FEM simulations. Within the given range of material properties, those four parameters can be quickly accessed by interpolating the data appended or …

The Use Of Item Response Theory In Survey Methodology: Application In Seat Belt Data, Mark K. Ledbetter, Norou Diawara, Bryan E. Porter

Mathematics & Statistics Faculty Publications

Problem: Several approaches to analyze survey data have been proposed in the literature. One method that is not popular in survey research methodology is the use of item response theory (IRT). Since accurate methods to make prediction behaviors are based upon observed data, the design model must overcome computation challenges, but also consideration towards calibration and proficiency estimation. The IRT model deems to be offered those latter options. We review that model and apply it to an observational survey data. We then compare the findings with the more popular weighted logistic regression. Method: Apply IRT model to the observed data …

Numerical Simulation For A Rising Bubble Interacting With A Solid Wall: Impact, Bounce, And Thin Film Dynamics, Changjuan Zhang, Jie Li, Li-Shi Luo, Tiezheng Qian

Mathematics & Statistics Faculty Publications

Using an arbitrary Lagrangian-Eulerian method on an adaptive moving unstructured mesh, we carry out numerical simulations for a rising bubble interacting with a solid wall. Driven by the buoyancy force, the axisymmetric bubble rises in a viscous liquid toward a horizontal wall, with impact on and possible bounce from the wall. First, our simulation is quantitatively validated through a detailed comparison between numerical results and experimental data. We then investigate the bubble dynamics which exhibits four different behaviors depending on the competition among the inertial, viscous, gravitational, and capillary forces. A phase diagram for bubble dynamics has been produced using …
