The Influence Of Classroom Management, Administrative Support, Parental Involvement, And Economic Factors On The Retention Of Novice Teachers, Katrina Moody Dwyer

Dissertations

The purpose of this study was to examine the impact of selected factors upon the intent of novice teachers to remain in the classroom. Teachers are leaving the profession in numbers that have prompted significant concern among policymakers and administrators. Many qualified college students are not considering the field of education as a potential career (Petty, 2007). Given that attrition rates among teachers are higher in their earliest years within the profession, it is essential to identify factors that contribute to the satisfaction and retention of novice teachers (Stockard & Lehman, 2004).

The primary data for this study were obtained …

Minimum Investment Requirement, Financial Integration And Economic (In)Stability: A Refinement To Matsuyama (2004), Haiping Zhang

Research Collection School Of Economics

This note proposes a simple, more precise, necessary condition for symmetry breaking in Matsuyama (Financial Market Globalization, Symmetry-Breaking, and Endogenous Inequality of Nations, Econometrica, 2004 ), i.e., the positive interest rate response to income changes, which essentially arises from the assumptions of financial frictions and minimum investment size requirement of individual projects. This condition also holds under the more general settings. Thus, this note o ers an empirically testable hypothesis, i.e., Matsuyama's symmetry breaking is more likely, if the interest rate response to income changes is positive and sufficiently large.

Predictive Regression Under Various Degrees Of Persistence And Robust Long-Horizon Regression, Peter C. B. Phillips, Ji Hyung Lee

Research Collection School Of Economics

The paper proposes a novel inference procedure for long-horizon predictive regression with persistent regressors, allowing the autoregressive roots to lie in a wide vicinity of unity. The invalidity of conventional tests when regressors are persistent has led to a large literature dealing with inference in predictive regressions with local to unity regressors. Magdalinos and Phillips (2009b) recently developed a new framework of extended IV procedures (IVX) that enables robtist chi-square testing for a wider class of persistent regressors. We extend this robust procedure to an even wider parameter space in the vicinity of unity and apply the methods to long-horizon …

Partial Least Squares Regression On Grassmannian Manifold For Emotion Recognition, M. Liu, R. Wang, Zhiwu Huang, S. Shan, X. Chen

Research Collection School Of Computing and Information Systems

In this paper, we propose a method for video-based human emotion recognition. For each video clip, all frames are represented as an image set, which can be modeled as a linear subspace to be embedded in Grassmannian manifold. After feature extraction, Class-specific One-to-Rest Partial Least Squares (PLS) is learned on video and audio data respectively to distinguish each class from the other confusing ones. Finally, an optimal fusion of classifiers learned from both modalities (video and audio) is conducted at decision level. Our method is evaluated on the Emotion Recognition In The Wild Challenge (EmotiW 2013). The experimental results on …

Adaptive Computer‐Generated Forces For Simulator‐Based Training, Expert Systems With Applications, Teck-Hou Teng, Ah-Hwee Tan, Loo-Nin Teow

Research Collection School Of Computing and Information Systems

Simulator-based training is in constant pursuit of increasing level of realism. The transition from doctrine-driven computer-generated forces (CGF) to adaptive CGF represents one such effort. The use of doctrine-driven CGF is fraught with challenges such as modeling of complex expert knowledge and adapting to the trainees’ progress in real time. Therefore, this paper reports on how the use of adaptive CGF can overcome these challenges. Using a self-organizing neural network to implement the adaptive CGF, air combat maneuvering strategies are learned incrementally and generalized in real time. The state space and action space are extracted from the same hierarchical doctrine …

The Influence Of Online Word-Of-Mouth On Long Tail Formation, Bin Gu, Qian Tang, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

The long tail phenomenon has been attributed to both supply side and demand side economies. While the cause on the supply side is well-known, research on the demand side has largely focused on the awareness effect of online information that helps consumers discover new and often niche products. This study expands the demand side factors by showing that online information also influences the long tail phenomenon through the informative effect, which affects consumers' evaluation of product quality. We examine the informative effect in the context of online WOM. Two sets of theories suggest opposite directions for the implication of the …

A Local Social Network Approach For Research Management, Xiaoyan Liu, Zhiling Guo, Zhenjiang Lin, Jian Ma

Research Collection School Of Computing and Information Systems

Traditional methods to evaluate research performance focus on citation count, quality and quantity of research output by individual researchers. These measures overlook the roles an individual plays in research collaboration, which is critical in an institutional research management environment due to the inherent interdependency among research entities. In order to address the organizational research management needs, we propose a research social network approach to better analyze local collaboration networks. For this purpose, we develop a new “collaboration supportiveness” measure to quantify an individual researcher's collaboration ability. Insights derived from this research are very helpful for managers to effectively allocate resources, …

Modeling Temporal Adoptions Using Dynamic Matrix Factorization, Freddy Chong-Tat Chua, Richard Jayadi Oentaryo, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The problem of recommending items to users is relevant to many applications and the problem has often been solved using methods developed from Collaborative Filtering (CF). Collaborative Filtering model-based methods such as Matrix Factorization have been shown to produce good results for static rating-type data, but have not been applied to time-stamped item adoption data. In this paper, we adopted a Dynamic Matrix Factorization (DMF) technique to derive different temporal factorization models that can predict missing adoptions at different time steps in the users' adoption history. This DMF technique is an extension of the Non-negative Matrix Factorization (NMF) based on …

Topicsketch: Real-Time Bursty Topic Detection From Twitter, Wei Xie, Feida Zhu, Jing Jiang, Ee Peng Lim, Ke Wang

Research Collection School Of Computing and Information Systems

Twitter has become one of the largest platforms for users around the world to share anything happening around them with friends and beyond. A bursty topic in Twitter is one that triggers a surge of relevant tweets within a short time, which often reflects important events of mass interest. How to leverage Twitter for early detection of bursty topics has therefore become an important research problem with immense practical value. Despite the wealth of research work on topic modeling and analysis in Twitter, it remains a huge challenge to detect bursty topics in real-time. As existing methods can hardly scale …

Testing Homogeneity In Panel Data Models With Interactive Fixed Effects, Liangjun Su, Qihui Chen

Research Collection School Of Economics

This paper proposes a residual-based LM test for slope homogeneity in large dimensional panel data models with interactive fixed effects. We first run the panel regression under the null to obtain the restricted residuals, and then use them to construct our LM test statistic. We show that after being appropriately centered and scaled, our test statistic is asymptotically normally distributed under the null and a sequence of Pitman local alternatives. The asymptotic distributional theories are established under fairly general conditions which allow for both lagged dependent variables and conditional heteroskedasticity of unknown form by relying on the concept of conditional …

Combining Attentional Control And Semantic Memory Retrieval: A Sensitive Marker For Early Stage Ad And Ad-Related Biomarkers In Healthy Older Adults, Andrew Jacob Aschenbrenner

All Theses and Dissertations (ETDs)

Past studies have shown that measures of attentional control and semantic memory retrieval are sensitive markers of Alzheimer disease: AD). The present study examined the utility of combining measures of attentional control and semantic retrieval within a single task to discriminate healthy aging from early stage AD and show sensitivity to AD biomarkers in healthy control individuals. On each trial of the present task, participants viewed a category: e.g. “a unit of time”) and verified whether a subsequent target item was an exemplar of the category: “hour”) or not: “clock”). Importantly, the nonmembers of the category were associatively related: e.g., …

Predictive Admission Criteria In Graduate Programs In Speech-Language Pathology, Mary Lloyd Moore

Dissertations

Speech-language pathology is a profession for which there is increasing demand as well as being one of the most desirable career paths in the United States. Graduation of qualified persons who can pass the Praxis exam is an essential outcome of all graduate programs in speech-language pathology. If predictors of competence could be identified before admission, graduate programs would be better able to select students who would maximize the expenditure of materials, energy, and expertise, thereby decreasing the potential failure for both students and universities. Therefore, this research addresses the extent to which selected variables may serve to predict success …

Tests, Tests, And More Tests: A New Era For Dementia Diagnosis, Jonathan Gooblar

All Theses and Dissertations (ETDs)

Cerebrospinal fluid: CSF) proteins correlate with pathological changes that are hallmarks of Alzheimer’s disease: AD). CSF biomarkers have been used in research settings to predict AD diagnosis and rate of cognitive decline, however their use in clinical settings is limited. Given their potential utility in identifying preclinical AD and in increasing diagnostic confidence in clinical settings, we sought to understand how clinicians use CSF biomarkers in conjunction with other clinical details to diagnose AD. Participants: N = 193) were physicians and other medical professionals who routinely evaluate older adults for neurodegenerative disease. In a within-subjects factorial design, participants were randomized …

The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey

All Theses and Dissertations (ETDs)

Audiovisual: AV) speech perception is perception in which both auditory and visual information is available in order to understand a talker, compared to an auditory signal alone, during face-to-face communication. This form of communication yields significantly higher word recognition performance as compared to either sensory modality alone, constituting a general AV advantage for speech perception. Despite an overall AV advantage, older adults seem to receive less benefit from this bimodal presentation than do younger adults. However, there is evidence to suggest that not all age-related deficits in AV speech perception are of a sensory nature, but are also influenced by …

An Algorithm For Triangulating 3d Polygons, Ming Zou

All Theses and Dissertations (ETDs)

In this thesis, we present an algorithm for obtaining a triangulation of multiple, non-planar 3D polygons. The output minimizes additive weights, such as the total triangle areas or the total dihedral angles between adjacent triangles. Our algorithm generalizes a classical method for optimally triangulating a single polygon. The key novelty is a mechanism for avoiding non-manifold outputs for two and more input polygons without compromising opti- mality. For better performance on real-world data, we also propose an approximate solution by feeding the algorithm with a reduced set of triangles. In particular, we demonstrate experimentally that the triangles in the Delaunay …

Emg-Emg Coherence Analysis Of Elbow And Shoulder Muscles, Manu Stephen

All Theses and Dissertations (ETDs)

Motor coordination can be described by the activation of a few intermuscular coordination patterns, or muscle synergies. Muscle synergy can be defined as a relatively fixed pattern of activation across a set of muscles. The neural mechanisms underlying muscle synergies remain to be fairly unknown. Through a muscle synergy study [13], co-activation in muscle pairs was discovered through a non-negative matrix factorization: NMF) analysis. In order to evaluate the same muscles under the frequency domain, coherence analysis: a correlational method) was used. Additionally, a comparison can be made to determine if the resulting muscle pairs overlap with the muscle pairs …

A Study Of The Aiken-Rhett Stew Stove, Julia Anne Tew

All Theses

The stew stove found in the kitchen of the Aiken-Rhett House in Charleston, South Carolina is a rare and well-preserved example of antebellum stew stove technology. This masonry stove was installed in the main kitchen of Governor William Aiken in 1858 and contains six cast iron stew holes and a set kettle. Masonry cook stoves appeared in the United States as early as the mid-eighteenth century. Stoves like this were not an American invention. A French device known as the potager is the predecessor and inspiration for such devices. This potager eased the cook's labors in preparing meals and offered …

An Examination Of Twitter's Role In The Formation Of Collegiate Sport Fans' Allegiance Using The Revised Psychological Continuum Model (Pcm), Sukjoon Yoon

All Theses

Allegiance has long been considered one of the most notable research topics in sport studies (Funk & Pastore, 2000; Wann & Branscombe 1990). Allegiant fans are those who have formed strong connections to their favorite team, and these attitudes strengthen their psychological involvement. Twitter has grown dramatically since its inception in 2006, totaling more than 500 million users as of early 2013 (Gupta, Goel, Lin, Sharma, Wang, & Zadeh, 2013). Twitter is one of the most popular communication technologies used by both fans and sport organizations (Clavio, 2011), and allows individuals, organizations, and other social groups to connect with one …

Cost And Embodied Energy Optimization Of Rectangular Reinforced Concrete Beams, Alexander Kosloski

All Theses

Concrete has a large environmental footprint so it is desirable to find ways to efficiently design structural members. Engineers can exercise their abilities early on in the design phase of construction projects to reduce the environmental footprint by minimizing the amount of materials required. One way to achieve these results is to optimize the design of structural concrete. In this study, simple-span rectangular reinforced concrete (RC) beams with a range of different bending moments were analyzed. The primary goal was to combine life cycle analysis (LCA), numerical optimization, and reinforced concrete mechanics to create a framework for designing efficient RC …

Twelve Mile Creek Channel Morphology, Substrate Composition, And The Macroinvertebrate Community Changes Resulting From Multiple Dam Removals, Patricia Whitener

All Theses

Dam removal is gaining global attention as a potential restoration tool for impacted rivers. As the practice of dam removal increases, physical, chemical and biological monitoring before and after dam removal is essential to our understanding of the ecological consequences of this type of disturbance. Under the Lake Hartwell Restoration and Compensation Determination Plan, two dams (>9 m height) were removed from the Twelve Mile Creek watershed (170 km2) in Pickens county, South Carolina. To assess the short term impacts of dam removal on the Twelve Mile Creek ecosystem we conducted biomonitoring of macroinvertebrate species and surveys of river …

Creating Tradition: Change Ringing And The Myth Of The 'Holy City', Charlotte Hewitt Causey

All Theses

This thesis analyzes the recent creation of tradition surrounding church bells and bell towers in Charleston, South Carolina. Church bells have been a significant feature of Charleston’s aural landscape since the mid-eighteenth century when St. Michael’s hung a ring of bells in the tower that still dominates the intersection of Meeting and Broad Streets. The histories of four churches, St. Michael’s (1751), the Cathedral of St. Luke and St. Paul (1811), St, Matthew’s Lutheran (1867), and Grace Episcopal (1846) affirms the important role that bells played for these congregations. The bells installed in these churches and the uses to which …
