What Does Time Management Mean To You? Exploring Measures Of Time Management And Group Differences., Allison Burrus

Dissertations

For centuries people have been trying to find ways to effectively manage their time. Meanwhile, research in this area has lagged and provided inconsistent results about the outcomes (i.e., well-being and job performance) of the use of time management behaviors. A potential reason for the inconsistent results is the lack of a universal conceptualization of time management making it difficult to compare results. Further, it may be that certain groups use and/or interpret time management behaviors in different ways. This study investigated three of the most popular measures of time management concurrently. First, the measures were examined for statistical artifacts, …

Towards Completely Automated Glycan Synthesis, Matteo Panza

Dissertations

Carbohydrates are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. Although there has been continued interest in the synthesis of carbohydrates, chemical methods require specialized knowledge and hence remain cumbersome. The need for development of rapid, efficient and operationally simple procedures has come to the fore. This dissertation focuses on the development of a fully automated platform that will enable both experts and non-specialists to perform the synthesis of glycans. Existing automated methods for the synthesis of oligosaccharides are highly sophisticated, operationally complex, and require significant user know-how. By contrast, high performance liquid chromatography (HPLC) …

The Role Of Multidrug Resistance Regulators Mara, Soxs, Rob And Rama In Regulating Virulence Traits In Salmonella Enterica, Srinivas Thota

Dissertations

Enteric pathogens sense numerous signals specific to the anatomical location in the intestine and integrate them with the complex regulatory networks to temporally and spatially regulate their virulence genes. MarA, SoxS, Rob and RamA are homologous transcription factors that belong to AraC family of proteins in Salmonella enterica that primarily were thought to be involved in rendering antibiotic resistance to bacteria by up regulating efflux pumps and down regulating outer membrane porins. The fact that these transcription factors respond to the same intestinal compounds that regulate virulence genes in Salmonella motivated us to look for other roles of these transcription …

Regional And Historical Influences On The Spatial Distribution Of Neotropical Trees, Maria Isabel Loza

Dissertations

At small spatial scales, the composition of species assemblages depends on local conditions and the dispersal of propagules from surrounding regions. In turn, processes taking place at broad temporal and spatial scales, including changes in regional physiography and climate, shape the species pools in these source regions. This dissertation seeks to understand the effects of regional and historical processes on the spatial distribution of Neotropical tree species. In chapter 1, I investigate regional enrichment of local species assemblages testing two hypothesis: i) local species assemblages are enriched by unfiltered species pools, which are composed of all species that can …

Difficulty accessing services then can inhibit adjustment and may lead to homelessness.

The purpose of this study is to investigate the issue of homelessness as experienced by immigrants within an urban community. A case study will highlight the experience of a homeless immigrant family, as defined …

The Effect Of Union Affiliation On Salary For Female Community College Faculty, Kathleen Kanz White

Dissertations

There is a substantial pay disparity between the highest and lowest paid full-time community college faculty members, more so for women. Faculty unions, which are common at community colleges, are believed to increase pay equity, although research on unions is limited. This study provided evidence addressing gaps in the literature regarding the community college workforce and unionization in higher education. No previous research has been conducted at the community college level examining specific union affiliation and the role it plays in salary.

The purpose of the study was to examine salary variables for female community college faculty members employed in …

Can Free College Programs Level The Playing Field? An Exploratory Study Of Understanding Non-Economic Persistence Barriers For Low-Income Students, Alan Byrd

Dissertations

The rising cost of higher education has created substantial access and persistence barriers for low-income students. Consequently, gaps in educational attainment between low-income students and their middle- and high-income peers have continued to widen over the last few decades. Colleges and universities have taken notice of these growing disparities, and several institutions have responded by developing need-based financial aid programs to close unmet need gaps for Pell Grant recipients. These last-dollar financial aid programs have opened doors for more low-income students to attend selective institutions, but it is unclear how these programs will influence their persistence and completion rates. The …

Supervisory Working Alliance As A Predictor For Counselor Burnout: The Potential Mediating Role Of Supervisee Nondisclosure, Amanda Bohnenstiehl

Dissertations

Clinical supervision sometimes lacks the elements necessary for a rigorous, helpful, and meaningful experience for the supervisee. The purpose of this study was to examine the relationships between the supervisory working alliance, supervisee nondisclosure (i.e., when a supervisee does not communicate information that would otherwise be shared with the supervisor), and counselor burnout, specifically in a sample of counselors, social workers, and psychologists pursuing their original state licenses. Nondisclosure was examined to determine if it was a mediator of the relationship between the supervisory working alliance and burnout. Participants (n = 288) completed a demographic questionnaire, the supervisee form …

Recover Data In Sparse Expansion Forms Modeled By Special Basis Functions, Abdulmtalb Mohamed Hussen

Dissertations

In data analysis and signal processing, the recovery of structured functions (in terms of frequencies and coefficients) with respect to certain basis functions from the given sampling values is a fundamental problem. The original Prony method is the main tool to solve this problem, which requires the equispaced sampling values.

In this dissertation, we use the equispaced sampling values in the frequency domain after the short time Fourier transform in order to reconstruct some signal expansions, such as the exponential expansions and the cosine expansions. In particular, we consider the case that the phase of the cosine expansion is quadratic. …

An Exploration Of Contextual Factors Of Weight-Based Discrimination Against Business Leaders, Ellen Hermann Lynch

Dissertations

Two-thirds of the adult population of the United States are considered overweight (Ogden, Carroll, Kit, & Flegal, 2013) and are susceptible to weight-based discrimination in the workplace (Rudolph, Wells, Weller, & Baltes, 2009). The weight-based discrimination experienced by business leaders is relatively unknown. The present research used Leader Categorization Theory (Lord & Maher, 1991) as a framework to examine the extent to which a business leader’s weight is associated with their perceived leadership qualities and effectiveness in two studies. The first study isolated the relationship between the base rate of weight in an organization and the assumed weight of the …

Evaluating Controlled Substance Documentation In An Electronic Medical Record, Delora Brooks

Dissertations

The Centers for Disease Control and Prevention (CDC) directives issued in 2016 gave guidelines for safely prescribing opiates; however, primary source discussions about methods used for documenting opioid and controlled substance monitoring within an electronic medical record (EMR) are limited (Hussain, Nelson, Polston & Zheng, 2019). This leaves individual providers to determine the appropriate way to document. Inconsistent documentation may not protect providers or organizations from regulatory, civil or criminal liability. As stated by Raveesh, Nayak & Kumbar (2016), “The best way to handle medico-legal issues is by preventing them”. Even with the advent and widespread use of EMRs, documentation …

Chemical Synthesis Of Oligosaccharides From Human Milk, Mithila Dulanjalee Bandara Weerasooriya Mudiyanselage

Dissertations

Human milk oligosaccharides (HMO) are a family of structurally related glycans that are highly abundant in breast milk. Oligosaccharide fraction is the third largest solid component in human milk after lactose and lipids. There is an accumulating evidence that HMO can provide significant benefits to the breast-fed infants. However, understanding of the exact HMO functions is still incomplete due to the lack of individual compounds in sufficient quantities. Therefore, development of expeditious strategies for the chemical synthesis of HMO has been increasingly important. Among all the methods available for oligosaccharide synthesis, armed-disarmed strategy introduced by Fraser-Reid is based on chemoselective …

The Relationship Of Self-Directed Learning Readiness And Completion Of Officers In The Army War College Distance Education Program, Kevin Mangan

Dissertations

Today, more adults are participating in online education than ever before. The latest data from the Department of Educational Statistics show an increase of students taking all coursework online grew to 15.4% (Ginder, Kelly-Reid, & Mann, 2018). Despite this trend, some adults lack the readiness to engage in formal adult education. Readiness and other factors such as time and personal matters adults encounter are some of the most significant challenges for institutions in addressing attrition rates, which average 38% (USDE, 2011). The Army higher education programs experience the same problem in their educational institutions (U.S. Army War College Data, 2016). …
