Subjective Usability, Mental Workload Assessments And Their Impact On Objective Human Performance, Luca Longo

Articles

Self-reporting procedures and inspection methods have been largely employed in the fields of interaction and web-design for assessing the usability of interfaces. However, there seems to be a propensity to ignore features related to end-users or the context of application during the usability assessment procedure. This research proposes the adoption of the construct of mental workload as an additional aid to inform interaction and web-design. A user-study has been performed in the context of human-web interaction. The main objective was to explore the relationship between the perception of usability of the interfaces of three popular web-sites and the mental workload …

A Conceptual Framework For A Software Development Process Based On Computational Thinking, Catherine Higgins, Ciaran O'Leary, Orla Hanratty, Fredrick Mtenzi

Articles

A software development process is a mechanism for problem solving to help software developers plan, design and structure the development of software to solve a problem. Without a process to guide the structured evolution of a solution, it is extremely likely that at least some aspect of the resulting software will be omitted or incorrectly implemented. Even though the importance of utilising a software process for solving problems is accepted in the business and academic communities, it is a topic that is addressed very lightly (if at all) in most freshman undergraduate computing courses with most courses focussing on programming …

Operator Locality In The Quantum Simulation Of Fermionic Models, Vojtěch Havlíček, Matthias Troyer, James D. Whitfield

Dartmouth Scholarship

Simulating fermionic lattice models with qubits requires mapping fermionic degrees of freedom to qubits. The simplest method for this task, the Jordan-Wigner transformation, yields strings of Pauli operators acting on an extensive number of qubits. This overhead can be a hindrance to implementation of qubit-based quantum simulators, especially in the analog context. Here we thus review and analyze alternative fermion-to-qubit mappings, including the two approaches by Bravyi and Kitaev and the Auxiliary Fermion transformation. The Bravyi-Kitaev transform is reformulated in terms of a classical data structure and generalized to achieve a further locality improvement for local fermionic models on a …

Is Having Too Many Aggravating Factors The Same As Having None At All?: A Comment On The Hidalgo Cert. Petition, Chad Flanders

All Faculty Scholarship

While the Court does not dispute that at first blush the defendant's argument appears logical, it is disturbed by the prospect of how one determines the point at which the number of aggravating circumstances causes the death penalty statute to be generally unconstitutional. Is the Court to engage in some mathematical calculation as to who might be covered by the statute and who is not; and if so, what would be reasonable and logical factors to include in the formula? Can the Court arbitrarily declare that fifty aggravating circumstances is too many but forty-nine is permissible? Even assuming one could …

The Relative Effectiveness Of Course Delivery Methodology On Student Success, Retention, And Persistence In Remedial Mathematics, John P. Eveland

Murray State Theses and Dissertations

There are a substantial number of studies that consider the effectiveness of online instructional methodologies in general, but there is sparse previous work specifically targeting developmental mathematics students in community colleges. This study examines the relative effectiveness of online versus traditionally delivered developmental mathematics courses at Somerset Community College (SCC) in Somerset, Kentucky. At SCC, developmental mathematics is divided into three consecutive courses, MAT 055, MAT 065, and MAT 085, and this study considered each of these courses separately.

For this study, each student enrollment in any of SCC’s developmental mathematics courses was obtained for students in the Fall 2011 …

Concurrent Validity Of The Missouri Adaptive Behavior Inventory, Hannah Janecek

Murray State Theses and Dissertations

This study was designed to determine the concurrent validity of the Missouri Adaptive Behavior Inventory (MABI) by comparing it to the Adaptive Behavior Assessment ScaleThird Edition (ABAS-3). The MABI is an unpublished measure of adaptive behavior developed to specifically measure adaptive functioning required by federal statute. The ABAS-3 is a norm-referenced, valid, and reliable measure of adaptive behavior published in 2015. Twenty-five children were administered the MABI and the ABAS-3 in a counter-balanced manner, and raw scores were statistically compared using Pearson correlations. As expected, numerous statistically significant correlations were found among the MABI subtests and between the MABI and …

Kinetic Analysis And Mechanochemical Syntheses Of Palladium Complexes, Jonathon Zachary

Murray State Theses and Dissertations

Mechanochemical synthesis is a rapidly developing, more environmentally friendly alternative to traditional solution based syntheses. Mechanochemical methods often result in higher overall yields, minimize undesirable side reactions, and present cleaner more concise methods for compound preparation. This work will address the syntheses of three dialkyl 2,2′-bipyridyl-4,4′-dicarboxylate complexes of palladium(II) iodide and the kinetics of these reactions. Then, this work will address the improved synthesis and purification of 1,3-dimethyl-1H-benzimidazolium iodide and the synthesis of diiodo-bis(1,3-dimethyl benzimidazol-2-ylidene) palladium(II).

The successful synthesis of dialkyl 2,2′-bipyridyl-4,4′-dicarboxylate complexes of palladium(II) iodide was carried out under solvent free ball milling conditions and the kinetic analysis was …

A Quartz Crystal Microbalance Study Of Thiol:Ene Poly(Ionic Liquid) Polymerization And Gas Absorption, Yueming Wu

Murray State Theses and Dissertations

ABSTRACT

The polymerization process of, and gas absorption by, imidazolium-containing thiol:ene poly (ionic liquid)s (PILs), prepared from bisallylimidazolium bis(trifluoromethyl sulfonyl)imide [NTf₂^-] and pentaerythritoltetrakis(3 mercaptopropionate), was studied. The thiol:ene PILs examined were recently reported by groups at Murray State University. The advantage of thiol:ene PILs over other reported PILs is that thiol:ene polymers are made rapidly by UV exposure and exhibit high mechanical and thermal stability due to high cross-linking. The properties of interest for the thiol:ene PILs were studied using a quartz crystal microbalance (QCM). QCM techniques are based on the piezoelectric effect, where certain crystals (e.g., …

Implementation Of A Flipped Classroom In A Non-Majors’ Biology Course, Leah Good

Murray State Theses and Dissertations

Changes to teaching practices have been requested in almost every field of science and mathematics but their implementation can be daunting. The flipped classroom has become a popular method in K-16 education for integrating active learning in the classroom. Research on the implementation of flipped classrooms has been met with mixed results, however. I sought to determine the effectiveness of the flipped classroom while addressing methodology needs cited by past studies including: using both faculty and student demographic variables, addressing assessment performance using concept inventories, and studying faculty who are not experts in education. I found that flipped and non-flipped …

Neural Network Predictions Of A Simulation-Based Statistical And Graph Theoretic Study Of The Board Game Risk, Jacob Munson

Murray State Theses and Dissertations

We translate the RISK board into a graph which undergoes updates as the game advances. The dissection of the game into a network model in discrete time is a novel approach to examining RISK. A review of the existing statistical findings of skirmishes in RISK is provided. The graphical changes are accompanied by an examination of the statistical properties of RISK. The game is modeled as a discrete time dynamic network graph, with the various features of the game modeled as properties of the network at a given time. As the network is computationally intensive to implement, results are produced …

Potential For Asymmetric Competition Among Co-Inhabiting Invasive Silver Carp And Native Shad Species In The Lower Midwest, Dalton D. Lebeda

Murray State Theses and Dissertations

In the United States, Silver Carp are an invasive voracious planktivorous fish that are capable of competing with many native fish species. Until the last decade, very little was known about how Silver Carp would interact with native fish species or how quickly their populations would expand. In the early 2000’s, established Silver Carp populations were reported in Kentucky Lake although they were reported in the Tennessee River much earlier (1987). Kentucky Lake is the first large flood storage reservoir that has been invaded by a reproducing population of Silver Carp in the United States. To date, control measures for …
