Evaluation Of Structural Equation Modeling (Sem) Fit Indices In Distinguishing Between Circumplex And Other Factor Models, Andrew J. Thurston
Evaluation Of Structural Equation Modeling (Sem) Fit Indices In Distinguishing Between Circumplex And Other Factor Models, Andrew J. Thurston
USF Tampa Graduate Theses and Dissertations
The circumplex offers a useful paradigm for simultaneously modeling relationships between latent variables and visually representing an individual’s profile. Previous research has demonstrated the Circular Stochastic Process Model (CSPM) can establish the presence of the circumplex in sample data using Confirmatory Factor Analysis (CFA), allowing researchers to test the circumplex with familiar global fit indices such as the Confirmatory Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Squared Error of Approximation (RMSEA), and Unbiased Standardized Root Mean Squared Residual (SRMRu). However, it is not yet clear if these fit indices are sensitive to detect circumplexes under a variety of conditions. …
Applications Of Agent Based Approaches In Business: A Three Essay Dissertation, Shankar Prawesh
Applications Of Agent Based Approaches In Business: A Three Essay Dissertation, Shankar Prawesh
USF Tampa Graduate Theses and Dissertations
The goal of this dissertation is to investigate the enabling role that agent based simulation plays in business and policy. The aforementioned issue has been addressed in this dissertation through three distinct, but related essays. The first essay is a literature review of different research applications of agent based simulation in various business disciplines, such as finance, economics, information systems, management, marketing and accounting. Various agent based simulation tools to develop computational models are discussed. The second essay uses an agent-based simulation approach to study important properties of the widely used most popular news recommender systems (NRS). This essay highlights …
Operational Performance Evaluation Of Four Types Of Exit Ramps On Florida's Freeways, Linjun Lu
Operational Performance Evaluation Of Four Types Of Exit Ramps On Florida's Freeways, Linjun Lu
USF Tampa Graduate Theses and Dissertations
This research focuses primarily on the analysis of exit ramp performance related to safety and operations. The safety analysis focuses on the impacts of different exit ramp types for freeway diverge areas and different factors contributing to the crashes that occur on the exit ramp sections. The operational analysis is based mainly on simulations by TSIS-CORSIM. Different ramp effects and guidance for selecting optimal exit ramp type are concluded. Issues related to ramp sections and crossroad sections are also demonstrated. Minimum ramp length and minimum distance between ramp terminal and downstream or upstream intersections are calculated. The operational analysis was …
