Relationships Between Landscape Factors And Crayfish Density And The Interacting Effects Of Grazing And Increased Sedimentation On Algal Biomass, Katheryn Haley Rose

Graduate Theses and Dissertations

In recent years in the United States there has been a rapid expansion in anthropogenic sources of sediment in streams including construction, agriculture, and drilling for natural gas. Potential effects land disturbance associated with activities from natural gas development on aquatic biota in surrounding streams have not yet been well documented. An increase in inorganic sediment in streams can be detrimental to organisms through a variety of mechanisms including alteration of dominant substrate type, higher turbidity resulting in lower visibility, and burial of food resources such as algae and detritus. Increasing sedimentation in stream environments through anthropogenic disturbance is a …

Identifying Emerging Researchers Using Social Network Analysis, Syed Masum Billah

Graduate Theses and Dissertations

Finding rising stars in academia early in their careers has many implications when hiring new faculty, applying for promotion, and/or requesting grants. Typically, the impact and productivity of a researcher are assessed by a popular measurement called the h-index that grows linearly with the academic age of a researcher. Therefore, h-indices of researchers in the early stages of their careers are almost uniformly low, making it difficult to identify those who will, in future, emerge as influential leaders in their field. To overcome this problem, we make use of Social network analysis to identify young researchers most likely to become …

Consumer Adoption Of Health Information Systems, Sankara Subramanian Srinivasan

Graduate Theses and Dissertations

At nearly 18 percent of the country's GDP, the U.S. healthcare industry continues to wrestle with growing cost and a quality of care that does not match the increased spending. The dominant focus to date has been on promoting Health IT (HIT) system implementation and digitizing health records at the provider's end, with scant attention to the role of the patient in the healthcare process. The source of inefficiency in the healthcare system is not only on account of shortcomings at the provider's end but also due to non-compliance (such as failing to adhere to medication advice and follow-up visits) …

The Role Of The Musical - Self In Promoting Career Longevity Among Music Therapists, Peter Davis

Theses & Dissertations

To attend to the musical and clinical needs of music therapy consumers, music therapists must attend to their own music so as to nurture their musical-self (Bruscia, 1987; Priestley, 1994; Robbins & Robbins, 1998). Yet, despite the fact that music is the basic tool music therapists rely upon to conduct their work (Aigen, 2005b; Brookins, 1984), the topic of nurturing the musical-self has received scarce, if any attention in the music therapy literature. The purpose of this study was to understand the views of professional music therapists in regard to the role of the musical-self in promoting career longevity among …

Post-Inpatient Attrition From Care “As Usual” In Veterans With Multiple Psychiatric Admissions, Nicholas W. Bowersox, Stephen M. Saunders, Bertrand Berger

Psychology Faculty Research and Publications

Disengagement from outpatient care following psychiatric hospitalization is common in high-utilizing psychiatric patients and contributes to intensive care utilization. To investigate variables related to treatment attrition, a range of demographic, diagnostic, cognitive, social, and behavioral variables were collected from 233 veterans receiving inpatient psychiatric services who were then monitored over the following 2 years. During the follow-up period, 88.0 % (n = 202) of patients disengaged from post-inpatient care. Attrition was associated with male gender, younger age, increased expectations of stigma, less short-term participation in group therapy, and poorer medication adherence. Of those who left care, earlier attrition was …

Improving Patient Length-Of-Stay In Emergency Department Through Dynamic Queue Management, Kar Way Tan, Hoong Chuin Lau, Francis Chun Yue Lee

Research Collection School Of Computing and Information Systems

Addressing issue of crowding in an Emergency Department (ED) typically takes the form of process engineering or single-faceted queue management strategies such as demand restriction, queue prioritization or staffing the ED. This work provides an integrated framework to manage queue dynamically from both demand and supply perspectives. More precisely, we introduce intelligent dynamic patient prioritization strategies to manage the demand concurrently with dynamic resource adjustment policies to manage supply. Our framework allows decision-makers to select both the demand-side and supply-side strategies to suit the needs of their ED. We verify through a simulation that such a framework improves the patients' …

Effect Of Electrostatic Spraying Of Food-Grade Organic And Inorganic Acids, And Grape Seed Extract On Salmonella Typhimurium And Escherichia Coli O157:H7 On Spinach And Iceberg Lettuce, Vijayalakshmi Ganesh

Graduate Theses and Dissertations

The safety of fresh produce is often challenged by the sporadic incidences of outbreaks owing to Salmonella Typhimurium (S.T.) and Escherichia coli O157:H7 (E.c.). Washing and current disinfection strategies do not completely decontaminate leafy greens such as spinach and iceberg lettuce. Therefore, more effective treatments are essential to ensure the microbial safety of the produce at the selling point. Here, a multiple hurdle approach was applied: (1) Natural antimicrobials - organic acids (malic, lactic and tartaric acids; MA, LA, TA, respectively) and plant extract (grape seed extract, GSE) and (2) Application method - Electrostatic spraying, was …

Ecological Importance Of Ectomycorrhizal Linkages In The Ozark Mountains And The Fernow Experimental Forests, Shelly Kendra Bursick

Graduate Theses and Dissertations

Underground stem-to-stem linkages involving ectomycorrhizal (ECM) fungi are probably important in forest ecosystems, since these linkages could assist in the survival of established trees as well as increasing the growth and development of seedlings and saplings. This study compared forest communities of the Ozark Mountains of northwest Arkansas and the Fernow Experimental Forest in West Virginia by examining species richness, diversity, relative abundance, and the potential for stems to exhibit spatial distribution and clustering patterns that reflected the existence of linkages by ECM fungi. Data on forest communities in the Ozarks were obtained from eight plot locations in Devil's Den …

Perceptions Of Poverty: The Evolution Of German Attitudes Towards Social Welfare From 1830 To World War I, Rebekah O'Zell Mcmillan

Graduate Theses and Dissertations

Today's Western European countries have the world's most extensive government Social welfare systems, beginning with Germany as the forerunner. Prior to the eventual 20th century German welfare state, Germany was not devoid of distributing aid to combat the effects of poverty. Religious and public benevolent institutions, several centuries earlier, managed local poverty, resulting in an interesting relationship between the German citizens and these charities. The willingness of these institutions to address the poverty issue opened the door for the 20th century German welfare state to emerge.

This study examines the evolution of the attitudes towards poverty in nineteenth century Germany. …

Distortion-Tolerant Communications With Correlated Information, Ning Sun

Graduate Theses and Dissertations

This dissertation is devoted to the development of distortion-tolerant communication techniques by exploiting the spatial and/or temporal correlation in a broad range of wireless communication systems under various system configurations. Signals observed in wireless communication systems are often correlated in the spatial and/or temporal domains, and the correlation can be used to facilitate system designs and to improve system performance. First, the optimum

node density, i.e., the optimum number of nodes in a unit area, is identified by utilizing the spatial data correlation in the one- and two-dimensional wireless sensor networks (WSNs), under the

constraint of fixed power per unit …

Developing A Presumptive Test For Select Synthetic Cannabinoids, Carrie Snyder

Graduate Theses and Dissertations

Synthetic cannabinoids (SC's) began to gain popularity around the world in 2009. Since then, many of the compounds have been outlawed and methods developed to detect them and their metabolites using mass spectrometry. Our work investigated the possibility of developing a colorimetric presumptive test. The SC JWH-019 was synthesized and its ketone targeted as a possible reaction site. Many SC's contain ketones and thus a reaction at this site would be applicable to many of the compounds. Since JWH-019 is costly and time consuming to synthesize, much of the experimental work was done using benzophenone (BP). BP contains a diaryl …
