Determining Journal Article Impact In The School Psychology Literature Through Bibliometric Analyses, Patrick Mcnicholas

Electronic Theses and Dissertations Archive

Bibliometric analyses have been the primary form of examining and evaluating literature within a field of study. By focusing on citation count and source, researchers have been able to identify journal articles considered to be high impact in reach and relevance, branding them citation classics in a field (Garfield, 1977, 1979). As time progresses, technology, methods, and metrics for conducting these analyses have improved, and although there have been several studies designed to identify citation classics and patterns of citations supporting them in school psychology literature (e.g., Liu & Oakland, 2016; Price, Floyd, Fagan, & Smithson, 2011), none have done …

Electronic Theses and Dissertations Archive

AbstractMeiners-Lovel, Lorraine A. PhD. The University of Memphis. Preschool Teachers Use of Book Sharing Strategies to Build Academic Language Skills. May, 2020. Emily Thrush, PhD. ArrayIt is essential to understand the role of preschool teachers in the linguistic preparation of young children for kindergarten and elementary school. This understanding becomes even more important as more American preschoolers attend group care and public universal pre-kindergarten becomes more common. Children must master the variety of language known as the academic register, academic language, or school language in order to be academically successful. Preschool teachers need to understand the features of academic language …

Research In Emerging Financial Technologies, Jonathan Lee Miller

Electronic Theses and Dissertations Archive

In chapter one we investigate the price clustering of non-fiat cryptocurrency exchange rates or the pricing of items in cryptocurrency such as bitcoin, which has been accepted as payment at a growing list of companies. For litecoin, a non-fiat currency, priced in terms of satoshi, one hundred millionth of a bitcoin, over 35% are priced at 100 satoshi increments, providing support for the negotiation hypothesis. There is also strategic pricing at 1 satoshi below or above the 100 satoshi increments. At the transaction level, we find that prices are mainly formed due to negotiations and strategic trading, instead of based …

Transactional Distance In Middle And High School Online Learning Environments: An Empirical Study, Silas Njoroge

Electronic Theses and Dissertations Archive

Understanding the communication gap due to the separation of teachers-students and students-students in online learning environments can have a profound impact on improving online learning. Moores Transactional Distance Theory (TDT) is an important pedagogical theory in distance learning that can be used to gain a better understanding of K-12 distance education practices. This study sought to empirically verify the theory by investigating the relationship of dialogue, structure, learner autonomy, and transactional distance (TD) perceived by students in K-12 Online Learning Environments (OLE). The study also investigated the effect of environmental and demographic factors on TD. Participants were selected from online …

Approaches For Analyzing Multivariate Mixed Endpoints With High-Dimensional Covariates., Yunusa Olufadi

Electronic Theses and Dissertations Archive

In clinical trials and observational studies, clinicians often observe measurements on multiple causes of clinical progression or synthesize information from various sources. These measurements are collected because a single outcome is usually inadequate to describe the disease complexities or because the primary outcomes of interest are abstract constructs (e.g., quality of life, disease conditions) that cannot be measured directly. It is usually necessary to collect multiple endpoints in order to fully understand the true associations that exist among several clinical outcomes and how they jointly affect the primary outcomes. In addition, such datasets are often useful for characterizing treatment effectiveness, …

Development Of Forecasting And Scheduling Methods And Data Analytics Based Controls For Smart Loads In Residential Buildings., S M Mahfuz Alam

Electronic Theses and Dissertations Archive

A smart building is the one that is equipped with automated systems such as lighting, shading, heating, ventilation, and air-conditioning (HVAC), etc., for fulfilling consumers demand. An efficient load forecasting system helps the building energy management system (BEMS) schedule the loads, operate the energy sources and energy storage systems effectively during peak hours to reduce cost of energy and remove burden on the grids. Furthermore, the load scheduling is a key element for demand side management (DSM) system to actively participate in demand response program. Researchers have been investigating on improved and effective load forecasting and load scheduling methods over …

Multivariate Modeling Of Cognitive Performance And Categorical Perception From Neuroimaging Data, Rakib Al-Fahad

Electronic Theses and Dissertations Archive

State-of-the-art cognitive-neuroscience mainly uses hypothesis-driven statistical testing to characterize and model neural disorders and diseases. While such techniques have proven to be powerful in understanding diseases and disorders, they are inadequate in explaining causal relationships as well as individuality and variations. In this study, we proposed multivariate data-driven approaches for predictive modeling of cognitive events and disorders. We developed network descriptions of both structural and functional connectivities that are critical in multivariate modeling of cognitive performance (i.e., fluency, attention, and working memory) and categorical perceptions (i.e., emotion, speech perception). We also performed dynamic network analysis on brain connectivity measures to …

Performance Beyond Ability: Exploring The Relationship Between Motivation And Mathematics Achievement At Community Colleges, Ezell Wesley Allen

Electronic Theses and Dissertations Archive

Mathematics achievement, both in high school and early in college, is one of the strongest predictors of college completion. Research has shown that math interest, utility, engagement, self-efficacy, and identity are related to mathematics achievement. Hence, this study uses structural equation modeling to evaluate Fords (2017) empirical model linking mathematics beliefs and achievement, which expanded on Eccles model of achievement-related choices (2005) and Middletons model of mathematics achievement (2013). This study also moves beyond the Allen (2019) limitations by exploring institutions that are different in geographic locations. With the new expanded scope, this study adds to the growing body of …

Administrators' Benevolent And Corrective Humor And Suspensions Of African American School Age Females, Roslyn E. Bacon

Electronic Theses and Dissertations Archive

African American female students suspension rates are rising and outpacing those of all categories of students, including African American males. This is due, in part, to an administrators over-reliance on zero-tolerance disciplinary policies, as well as a teachers negative perception of African American female students. Soaring rates of suspension contribute to school disengagement, high dropout rates, and a formidable risk of involvement in the school to prison pipeline. In addition to the toll these risks take on human lives, society loses the benefit of human productivity, taxable wages, and stable, thriving communities. As attention to the rising rate of suspension …

Engaging Critical Reflection And Authenticity In Higher Education: A Narrative Inquiry Into The Roles Of Educators In Architecture Education, Jennifer Barker

Electronic Theses and Dissertations Archive

In the 1980s, Donald Schn put forth his ideas on reflective practice that involved the architectural studio, and in particular, the tutorial interaction, as a model for knowing-in-action, reflection-in-action, and reflection-on-action. Schn (1984) noted, however, that the faculty involved appeared not to reflect on this reflective practice. With a history of apprenticeship, architectural education is dominated by the studio and while many architectural educators appreciate the attention Schns work has brought to the pedagogical model, others feel that more is demanded to shift it from a historically teacher-centered model, to one that is learner-centered (Webster, 2004, 2008; Mewburn, 2011). Calls …

A Closer Look At Eighth Grade Special Education Students Performance On High Stakes Testing: Examining The Compounding Effects Of Socioeconomic Status And Mobility Rate On Test Scores, Mary Brewer

Electronic Theses and Dissertations Archive

Despite the fact that the US spends millions of dollars on testing and instructional resources for students with exceptionalities (SWE) to participate on state tests, performance continues to be significantly below their general education peers. In an effort to determine if any additional factors may play a role in the performance discrepancy, two other factors, socio-economic status (SES) and mobility rate, were analyzed. Data from the Florida State Department of Education was used because of the public availability, the proposed generalizability of such a diverse state, and Florida being one of three states with the largest population of public education …

Writing Instruction For Students With Learning Disabilities: Examining Teacher Practice, Preparedness, And Self-Efficacy, Alycia M. Taylor

Electronic Theses and Dissertations Archive

ABSTRACT Writing is critical for high school students academic, social, and professional success. However, developing writing skills is a challenging process, particularly for students with learning disabilities (LDs). To produce high quality writing, substantial support from teachers is needed. Yet, many teachers are uninformed of how to assist students with LDs. Grounded in social cognitive and socio-cultural theories, the aim of this quantitative study was to expand the fields of writing instruction and LDs by comparing data from general and special education teachers. This study was designed to survey this population about their writing instruction, including the use of evidence-based …

Validity Evidence Related To The Internal Structure Of The High School Longitudinal Study Mathematics Attitude And Belief Scales, Jessica Webb

Electronic Theses and Dissertations Archive

Research has examined whether mathematics attitudes and beliefs are related to achievement and persistence in mathematics (e.g., Gottlieb, 2018; Kaspersen, Pepin, & Sikko, 2017a; Lauermann, Tsai, & Eccles, 2017; Lent, et al., 2018; Meyer, Fleckenstein, & Kller, 2019; Middleton, 2013; Peters, 2013; Sahin, Waxman, & Ekmekci, 2017; Wang, 2012; Wang, 2013; Yu & Singh, 2018). If attitudes and beliefs influence achievement and persistence and if they are malleable, educators can foster positive attitudes and beliefs as a way of positioning students for positive outcomes in mathematics. In order to study mathematics attitudes and beliefs and their relationship to desired outcomes, …

Childhood Obesity In California: The Impact Of School Lunch Options And Physical Education Standards In Public Elementary Schools, Audrey Connell

Scripps Senior Theses

Obesity is a biosocial phenomenon in that it is shaped by both biological and social processes. On the biological level, excess body fat increases one’s risk of placing the body in a non-homeostatic state that can weaken the immune response. On the social level, social inequalities are linked to obesity in the United States where racial and ethnic minority communities with low education and high poverty rates bear the largest burden of obesity. In various institutions, multiple actors such as food marketers, public health officials, policy makers, and school administrators dictate the opportunities available to children for them to reach …

Bayesian Modelling Of Nonlinear Poisson Regression With Artificial Neural Networks, Hansapani Rodrigo, Chris P. Tsokos

School of Mathematical & Statistical Sciences Faculty Publications

Modelling and prediction of count and rate responses have substantial usage in many fields, including health, finance, social, etc. Conventionally, linear Poisson regression models have been widely used to model these responses. However, the linearity assumption of the systematic component of linear Poisson regression models restricts their capability of handling complex data patterns. In this regard, it is important to develop nonlinear Poisson regression models to capture the inherent variability within the count data. In this study, we introduce a probabilistically driven nonlinear Poisson regression model with Bayesian artificial neural networks (ANN) to model count and rate data. This new …

On Cohen-Macaulay Hopf Monoids In Species, Jacob A. White

School of Mathematical & Statistical Sciences Faculty Publications

We study Cohen-Macaulay Hopf monoids in the category of species. The goal is to apply techniques from topological combinatorics to the study of polynomial invariants arising from combinatorial Hopf algebras. Given a polynomial invariant arising from a linearized Hopf monoid, we show that under certain conditions it is the Hilbert polynomial of a relative simplicial complex. If the Hopf monoid is Cohen- Macaulay, we give necessary and sufficient conditions for the corresponding relative simplicial complex to be relatively Cohen-Macaulay, which implies that the polynomial has a nonnegative h-vector. We apply our results to the weak and strong chromatic polynomials of …

The Quantization Of The Standard Triadic Cantor Distribution, Mrinal Kanti Roychowdhury

School of Mathematical & Statistical Sciences Faculty Publications

The quantization scheme in probability theory deals with finding a best approximation of a given probability distribution by a probability distribution that is supported on finitely many points. For a given k ≥ 2, let {Sj : 1 ≤ j ≤ k} be a set of k contractive similarity mappings such that Sj(x) = 1 2k−1x + 2(j−1) 2k−1 for all x ∈ R, and let P = 1 k Pk j=1 P ◦ S−1 j . Then, P is a unique Borel probability measure on R such that P has support the Cantor set generated by the similarity mappings …

Access Foundation Student Progression At Technological University Dublin: A Quantitative Study, Annette Forster, Fiona Faulkner, Mark Prendergast

Irish Journal of Academic Practice

Despite a global expansion of higher education in the twentieth century, inequalities in terms of student demographic still remain. The number of mature students (students aged 23 years and over) and students from lower socio-economic backgrounds in full-time higher education in the Republic of Ireland remains low. In order to address this issue, Dublin Institute of Technology (DIT) offered a one-year Access Foundation programme providing a route to higher education for mature students and young adults (students less than 23 years) from lower socioeconomic backgrounds. This study examines the factors affecting the progression of students on this programme to undergraduate …

New Technologies And New Spaces: Opportunities For Innovative Educational Environments, Gene Carolan, Cathal Curran, Alan Mccormack

Irish Journal of Academic Practice

Both the National Strategy for Higher Education to 2030 and the EU Commission's Report on the Modernisation of Higher Education emphasized the need for high-quality learning environments that are driven by state-of-the-art physical spaces and e-learning platforms. TU Dublin’s impending move to a new consciously designed campus at Grangegorman, and its adoption of the new virtual learning environment, Brightspace, are reflective of these trends. In anticipation of these developments, this paper explores how Brightspace might be integrated into the novel learning spaces created by TU Dublin’s migration to the Grangegorman Campus. The migration presents an excellent opportunity for students and …

Stem Or Steam?: The Critical Role Of Arts In Technology Education (And The Critical Role Of Art In Technology), Etain Watson

Irish Journal of Academic Practice

This paper outlines the interdependency between arts and technology, and explains the absolute necessity of keeping them together in our education systems. While arts and humanities can be successfully taught without technology, technology greatly enhances learning, and more technology is connected to arts in some way than any other use. According to PwC Chief Executive Luke Sayers, science, technology, engineering and mathematics (STEM) are the solution to our workforce and growth challenge. Deckers suggests that all the levels of Maslow’s Hierarchy exist in order to get us to the highest level where decisions are made according to aesthetics. Both STEM …

Sampling Device-Dependence Of Prokaryotic Community Structure On Marine Particles: Higher Diversity Recovered By In Situ Pumps Than By Oceanographic Bottles, Viena Puigcorbe, Clara Ruiz-Gonzalez, Pere Masque´, Josep M. Gasol

Research outputs 2014 to 2021

Microbes associated with sinking marine particles play key roles in carbon sequestration in the ocean. The sampling of particle-attached microorganisms is often done with sediment traps or by filtration of water collected with oceanographic bottles, both involving a certain time lapse between collection and processing of samples that may result in changes in particle-attached microbial communities. Conversely, in situ water filtration through submersible pumps allows a faster storage of sampled particles, but it has rarely been used to study the associated microbial communities and has never been compared to other particle-sampling methods in terms of the recovery of particle microbial …

Pedogenic Processes In A Posidonia Oceanica Mat, Nerea Pineiro-Juncal, Carmen Leiva-Duenas, Oscar Serrano, Miguel Angel Mateo, Antonio Martinez-Cortizas

Research outputs 2014 to 2021

Scientists studying seagrasses typically refer to their substratum as sediment, but recently researchers have begun to refer to it as a soil. However, the logistics of sampling underwater substrata and the fragility of these ecosystems challenge their study using pedological methods. Previous studies have reported geochemical processes within the rhizosphere that are compatible with pedogenesis. Seagrass substratum accumulated over the Recent Holocene and can reach several meters in thickness, but studies about deeper layers are scarce. This study is a first attempt to find sound evidence of vertical structuring in Posidonia oceanica deposits to serve as a basis for more …

Navigating Coasts Of Concrete: Pervasive Use Of Artificial Habitats By Shorebirds In The Asia-Pacific, Micha V. Jackson, Chi-Yeung Choi, Tatsuya Amano, Sora M. Estrella, Weipan Lei, Nial Moores, Taej Mundkur, Danny I. Rogers, Richard A. Fuller

Research outputs 2014 to 2021

Loss and degradation of wetlands has occurred worldwide, impacting ecosystems and contributing to the decline of waterbirds, including shorebirds that occur along the heavily developed coasts of the East Asian-Australasian Flyway (EAAF). Artificial (i.e. human-made) wetlands are pervasive in the EAAF and known to be used by shorebirds, but this phenomenon has not been systematically reviewed. We collated data and expert knowledge to understand the extent and intensity of shorebird use of coastal artificial habitats along the EAAF. We found records of 83 species, including all regularly occurring coastal migratory shorebirds, across 176 artificial sites with eight different land uses. …
