How the Conflict of Autonomous and Controlled Motivation Influences Sales Controls to Inside Sales Agents' Work Outcomes
Access:
Use of this item is restricted to the UNT Community
Through the use of multiple methodologies and analytical approaches, this dissertation combines (1) sales control; (2) call center service; and (3) motivational theory to extend sales control literature beyond its current state, to consider the conflicting motivational perspectives an inside sales agent has to experience. To achieve this unification, this dissertation consists of three essays intended to: (1) identify the influence of autonomous and controlled motivation on operational sales outcome controls and performance; (2) explore the influence these motivators have on sales controls and sales performance; and, (3) understand the impact of autonomous and controlled motivation on sales agent tenure.

The Crutch of Ritual: Social Control in the Modern American Capital Punishment System
Contemporary American capital punishment contains many processual elements, such as the prisoner's last meal and the cleansing of his body immediately before death, that serve no concrete, practical purpose but share a nature with ritual practices. In this project, I utilize a hermeneutic phenomenological lens to identify and list these ritual elements. I also use concepts drawn from the structural functionalist tradition to both analyze the specific purposes the elements serve within individual parts of the death penalty and to discuss the overarching result of the inclusion of these elements within the process as a whole. Ultimately, I find that the ritual elements present in the capital punishment process serve a social control purpose, insulating and reinforcing the death penalty as a whole. Ritual works to do this by controlling the behavior and image of the prisoner and emotionally soothing both participants of the process and the public at large.

Mining Biomedical Data for Hidden Relationship Discovery
Access:
Use of this item is restricted to the UNT Community
With an ever-growing number of publications in the biomedical domain, it becomes likely that important implicit connections between individual concepts of biomedical knowledge are overlooked. Literature based discovery (LBD) is in practice for many years to identify plausible associations between previously unrelated concepts. In this paper, we present a new, completely automatic and interactive system that creates a graph-based knowledge base to capture multifaceted complex associations among biomedical concepts. For a given pair of input concepts, our system auto-generates a list of ranked subgraphs uncovering possible previously unnoticed associations based on context information. To rank these subgraphs, we implement a novel ranking method using the context information obtained by performing random walks on the graph. In addition, we enhance the system by training a Neural Network Classifier to output the likelihood of the two concepts being likely related, which provides better insights to the end user.

Through His Own Words: An Exploration of the Pedagogy of Robert Marcellus
This dissertation presents the clarinet pedagogy of Robert Marcellus through reorganizing, documenting, and consolidating the archival recordings of summer master classes held at Northwestern University from 1977-1990. Pedagogical discussions and exercises are examined on topics such as wind, articulation, hand and finger position, and phrasing. Marcellus' interpretation and comments are discussed, along with musical examples from Cyrille Rose's 40 Studies for Clarinet, numbers 13, 21 and 32. This dissertation contains Marcellus' repertoire list and a sequence of study. Through this examination and consolidation of Marcellus' own words, this dissertation serves as a unique resource for those clarinetists interested in learning about this distinguished pedagogue.

A Feasibility Study of Cellular Communication and Control of Unmanned Aerial Vehicles
Consumer drones have used both standards such as Wi-Fi as well as proprietary communication protocols, such as DJI's OcuSync. While these methods are well suited to certain flying scenarios, they are limited in range to around 4.3 miles. Government and military unmanned aerial vehicles (UAVs) controlled through satellites allow for a global reach in a low-latency environment. To address the range issue of commercial UAVs, this thesis investigates using standardized cellular technologies for command and control of UAV systems. The thesis is divided into five chapters: Chapter 1 is the introduction to the thesis. Chapter 2 describes the equipment used as well as the test setup. This includes the drone used, the cellular module used, the microcontroller used, and a description of the software written to collect the data. Chapter 3 describes the data collection goals, as well as locations in the sky that were flown in order to gather experimental data. Finally, the results are presented in Chapter 4, which draws limited correlation between the collected data and flight readiness Chapter 5 wraps up the thesis with a conclusion and future areas for research are also presented.

Therapeutic Assessment as Preparation for Psychotherapy
This study examined the impact therapeutic assessment (TA) had on participants recruited from the UNT Psychology Clinic's waiting list. Using a pretest-posttest design, participants completed measures prior to and following their assessment. UNT Psychology Clinic archive data was used to compare this sample to clients who received traditional information gathering assessments with implicit measures, those receiving assessments relying on only self-report measures, and those who did not receive an assessment before beginning psychotherapy. The findings of this study vary based on the criteria being examined. Due to the small sample in the experimental group, no statistical significance was found through null hypothesis testing. However, the TA group's scores on the Outcome Questionnaire – 45 (OQ) and the Working Alliance Inventory (WAI) indicated better outcomes than those without a TA, with large effect sizes. Furthermore, those who received a TA were more likely than those without a TA to score below the clinically significant cutoff levels on the OQ. The study raises issues for consideration in what is deemed "effective" in therapeutic efficacy research.

Bio-Inspired Material Surfaces with Self-cleaning, Micromanipulation and Water Collection
Access:
Use of this item is restricted to the UNT Community
Geckos are famous for the skill of switchable adhesion that they use to stick on various surface while keep their fingers super clean. In the dissertation, a unique mechanism was discovered to explain gecko self-cleaning phenomena. Using atomic force microscopy (AFM), we managed to compare the microparticle-substrate adhesion and the microparticle-seta adhesion with a single seta bonded to the AFM cantilever. A dynamic effect was approved that high pulling-off speed could increase the microparticle-substrate adhesion and thus the self-cleaning appears at high moving speed. Based on the self-cleaning theory, a gecko-inspired N-doped graphene surface with switchable adhesion was achieved, which was designed into a bio-inspired micromanipulator with a success rate over 90%. When electrical bias was applied on this biomimetic surface, the charge concentration induced an electrical double layer (ELD) on the convex surfaces, which attracts polar water molecules to form a water bridge on it, significantly enhancing the adhesion on the wrinkled graphene surface, mimicking the capillary force on beetle feet. Therefore, the bio-inspired adhesive surface can be controlled with speed, electrical bias, humidity and different material surfaces. The water attraction phenomenon on the polarized surface was further tested for the potential application of water collection and evaporation in …

The Effectiveness of Child Parent Relationship Therapy (CPRT) for Fathers
High levels of quality father involvement in childhood are associated with children's socio-emotional, cognitive, and behavioral wellbeing. However, fathers can experience difficulty in building positive relationships with their kids due to work-life balance, lack of relational experience, and other life stressors. The purpose of this study was to assess the effectiveness of child-parent relationship therapy (CPRT) on fathers' parental empathy, parental stress, and child behavior problems. Though an abundance of literature exists to support the efficacy of CPRT, this was the first study to include a randomized controlled design with an all-male sample. This was also the first CPRT study to include both English and Spanish speaking fathers with intervention offered in both languages. Participants were 30 fathers (22 English, 8 Spanish; 53% Latino, 40% Caucasian, 7% Asian) with children between the ages of 3 and 10 (60% male, 40% female; 57% Latino/a, 37% Caucasian, 6% Asian). Fathers were randomly assigned to the experimental group (CPRT) (n = 14) or waitlist control group (n = 16). Results from 2 (Group) by 2 (Time) repeated measures ANOVAs did not yield statistically significant interaction effects on the dependent variables. However, results indicated a statistically significant main effect for time on each dependent …

Ligand Effects in Gold(I) Acyclic Diaminocarbene Complexes and Their Influence on Regio- and Enantioselectivity of Homogeneous Gold(I) Catalysis
Access:
Use of this item is restricted to the UNT Community
This dissertation focuses on the computational investigation of gold(I) acyclic diaminocarbene (ADC) complexes and their application in homogeneous gold(I) catalysis. Chapter 2 is an in-depth computational investigation of the σ- and π-bonding interactions that make up the gold-carbene bond. Due to the inherent conformation flexibility of ADC ligands, distortions of the carbene plane can arise that disrupt orbital overlap between the lone pairs on the adjacent nitrogen atoms and the empty p-orbital of the carbene. This study investigated the affect these distortions have on the strength of the σ- and π-bonding interactions. This investigation demonstrated that while these distortions can affect the σ- and π-bonding interactions, the ADC ligand have to become highly distorted before any significant change in energy of either the σ- or π-bonding interactions occurs. Chapter 3 is a collaborative investigation between experimental and computational methods, DFT calculations were employed to support the experimental catalytic results and determine the role that steric effects have in controlling the regioselectivity of a long-standing electronically controlled gold(I)-catalyzed tandem 1,6-enyne cyclization/hydroarylation reaction with indole. This study demonstrated that by sterically hindering nucleophilic attack of indole at the favored position, nucleophilic attack would occur at a secondary position leading to the selective …

Fabrication of Large-Scale and Thickness-Modulated Two-Dimensional Transition Metal Dichalcogenides [2D TMDs] Nanolayers
This thesis describes the fabrication and characterization of two-dimensional transition dichalcogenides (2D TMDs) nanolayers for various applications in electronic and opto-electronic devices applications. In Chapter 1, crystal and optical structure of TMDs materials are introduced. Many TMDs materials reveal three structure polytypes (1T, 2H, and 3R). The important electronic properties are determined by the crystal structure of TMDs; thus, the information of crystal structure is explained. In addition, the detailed information of photon vibration and optical band gap structure from single-layer to bulk TMDs materials are introduced in this chapter. In Chapter 2, detailed information of physical properties and synthesis techniques for molybdenum disulfide (MoS2), tungsten disulfide (WS2), and molybdenum ditelluride (MoTe2) nanolayers are explained. The three representative crystal structures are trigonal prismatic (hexagonal, H), octahedral (tetragonal, T), and distorted structure (Tʹ). At room temperature, the stable structure of MoS2 and WS2 is semiconducting 2H phase, and MoTe2 can reveal both 2H (semiconducting phase) and 1Tʹ (semi-metallic phase) phases determined by the existence of strains. In addition, the pros and cons of the synthesis techniques for nanolayers are discussed. In Chapter 3, the topic of synthesized large-scale MoS2, WS2, and MoTe2 films is considered. For MoS2 and WS2 films, the …
