Informal Karst Education In The United States And Internationally, Leslie A. North
Informal Karst Education In The United States And Internationally, Leslie A. North
USF Tampa Graduate Theses and Dissertations
Despite the abundance of karst terrains and the important role they play in a wide variety of roles including supplying freshwater drinking supplies, no single, comprehensive study investigates the role of informal education for the improved understanding and protection of the terrains. Commonly overlooked anthropogenic karst disturbances partially occur because of the poor dissemination of scientific information to the general populace and policymakers and budgetary and time constraints of municipalities, thus generating a need to use informal education to fill these shortcomings. The purpose of this study was to: 1) establish the status of and quantify the amount of karst-related …
Two-Language, Two-Paradigm Introductory Computing Curriculum Model And Its Implementation, Vladimir Zanev, Atanas Radenski
Two-Language, Two-Paradigm Introductory Computing Curriculum Model And Its Implementation, Vladimir Zanev, Atanas Radenski
Mathematics, Physics, and Computer Science Faculty Articles and Research
This paper analyzes difficulties with the introduction of object-oriented concepts in introductory computing education and then proposes a two-language, two-paradigm curriculum model that alleviates such difficulties. Our two-language, two-paradigm curriculum model begins with teaching imperative programming using Python programming language, continues with teaching object-oriented computing using Java, and concludes with teaching object-oriented data structures with Java.
Elementary Teachers' Views Of Environmental Education, Rose M. Hotchkiss
Elementary Teachers' Views Of Environmental Education, Rose M. Hotchkiss
Teaching & Learning Theses & Dissertations
The purpose of this research is to examine teachers' views of environmental education (EE) at the elementary level. The study addresses teachers' attitudes toward the EE at the elementary school level and their self-efficacy in teaching EE.
The study's sample consisted of 201 randomly selected kindergarten through fifth grade United States public school teachers. The participants completed an on-line survey with eight percent of the respondents participating in follow up interviews. The questionnaire measured two constructs; Teachers Attitudes Toward EE and Teacher Efficacy in EE. Teachers Attitudes Toward EE had 3 subscales; Advocacy for EE, Stewardship in EE, …
Kernel-Based Interior-Point Methods For Cartesian P*(Κ)-Linear Complementarity Problems Over Symmetric Cones, Goran Lesaja
Kernel-Based Interior-Point Methods For Cartesian P*(Κ)-Linear Complementarity Problems Over Symmetric Cones, Goran Lesaja
Department of Mathematical Sciences Faculty Publications
We present an interior point method for Cartesian P*(k)-Linear Complementarity Problems over Symmetric Cones (SCLCPs). The Cartesian P*(k)-SCLCPs have been recently introduced as the generalization of the more commonly known and more widely used monotone SCLCPs. The IPM is based on the barrier functions that are defined by a large class of univariate functions called eligible kernel function which have recently been successfully used to design new IPMs for various optimization problems. Eligible barrier (kernel) functions are used in calculating the Nesterov-Todd search directions and the default step-size which leads to a very good complexity results for the method. For …
Unified Analysis Of Kernel-Based Interior-Point Methods For P *(Κ)-Lcp, Goran Lesaja, C. Roos
Unified Analysis Of Kernel-Based Interior-Point Methods For P *(Κ)-Lcp, Goran Lesaja, C. Roos
Department of Mathematical Sciences Faculty Publications
We present an interior-point method for the P∗(κ)-linear complementarity problem (LCP) that is based on barrier functions which are defined by a large class of univariate functions called eligible kernel functions. This class is fairly general and includes the classical logarithmic function and the self-regular functions, as well as many non-self-regular functions as special cases. We provide a unified analysis of the method and give a general scheme on how to calculate the iteration bounds for the entire class. We also calculate the iteration bounds of both long-step and short-step versions of the method for several …
Meander Graphs And Frobenius Seaweed Lie Algebras, Colton Magnant, Vincent E. Coll, Anthony Giaquinto
Meander Graphs And Frobenius Seaweed Lie Algebras, Colton Magnant, Vincent E. Coll, Anthony Giaquinto
Department of Mathematical Sciences Faculty Publications
The index of a seaweed Lie algebra can be computed from its associated meander graph. We examine this graph in several ways with a goal of determining families of Frobenius (index zero) seaweed algebras. Our analysis gives two new families of Frobenius seaweed algebras as well as elementary proofs of known families of such Lie algebras.

Long Path Lemma Concerning Connectivity And Independence Number, Shinya Fujita, Alexander Halperin, Colton Magnant
Department of Mathematical Sciences Faculty Publications
We show that, in a k-connected graph G of order n with α(G)=α, between any pair of vertices, there exists a path P joining them with
|P|≥min{n,(k−1)(n−k)/α +k}.
This implies that, for any edge e∈E(G), there is a cycle containing e of length at least
min{n,(k−1)(n−k)/α +k}.
Moreover, we generalize our result as follows: for any choice S of s≤k vertices in G, there exists a tree T whose set of leaves is S with
|T|≥min{n,(k−s+1)(n−k)/α +k}.
