Concept Graphs: Applications To Biomedical Text Categorization And Concept Extraction, Said Bleik

Dissertations

As science advances, the underlying literature grows rapidly providing valuable knowledge mines for researchers and practitioners. The text content that makes up these knowledge collections is often unstructured and, thus, extracting relevant or novel information could be nontrivial and costly. In addition, human knowledge and expertise are being transformed into structured digital information in the form of vocabulary databases and ontologies. These knowledge bases hold substantial hierarchical and semantic relationships of common domain concepts. Consequently, automating learning tasks could be reinforced with those knowledge bases through constructing human-like representations of knowledge. This allows developing algorithms that simulate the human reasoning …

Escherichia Coli 2-Oxoglutarate Dehydrogenase Multienzyme Complex: E1 And E2 Substrate Specificty, E1 Carboligase Activity, And E2 Interchain Succinyl Transfer, Da Jeong Shim

Dissertations

Escherichia coli (E. coli) 2-oxoglutarate dehydrogenase multienzyme complex (OGDHc) contains three components: a thiamin di phosphate (ThD P) dependent 2-oxogl utarate dehydrogenase (E1 o), a di hydrol i poylsucci nyl transferase (E2o), and a di hydrol i poyl dehydrogenase (E3). The first two components carry out the principal reactions for succinyl CoA formation while the third one reoxidizes dihydrolipoamide to lipoamide. This mechanism is similar to other 2-oxoacid dehydrogenase complexes, including pyruvate dehydrogenases (PDHc) and branched-chain dehydrogenases.

E1o of the E. coli OGDHc was engineered to accept unnatural substrates. The natural substrate for E1 o is 2-oxogl utarate …

Hosx: Hospital Operations Excellence Model, Shivon S. Boodhoo

Dissertations

Hospital performance can be evaluated in four categories: (i) quality of care, (ii) process of care (iii) financial and (iv) operations productivity. Of these, ‘quality of care’ is the most widely reported and studied measure of performance, and focuses primarily on the clinical outcomes of the patient. In contrast, operations productivity and efficiency is the least studied measure, and currently there is limited ability to evaluate how efficiently the hospital has used its resources to deliver healthcare services. Cost containment in the healthcare industry is a challenging problem, and there is a lack of models and methods to benchmark hospital …

The Investigation Of Iron(Ii) Complexes And Their Catalytic Applications, Matthew Joseph Lenze

Dissertations

Several new η5-indenyl (Ind) complexes of iron featuring phosphinooxazoline (PHOX) ligands were synthesized and spectroscopically characterized and in a few cases structurally. The complexes were synthesized using phosphinooxazoline ligands and the corresponding iron precursor [Fe(η5-Ind) I(CO)2], yielding novel piano-stool iron complexes of the general formula [Fe(η5-Ind)(CO)(PHOX)]+ in 73% to 81% isolated yields. The complexes were tested for their efficacy in a carbon-carbon bond formation known as the Mukaiyama aldol reaction. The [Fe(η5-Ind)(CO)(PHOX)]+ complexes were capable of activating the carbonyl of aromatic aldehydes towards by attack 1-(tertbutyldimethylsilyloxy)-1-methoxyethene to form the expected silyl protected β-hydroxyesters. In these complexes, the η5-η3 haptotropic shift …

An Implementation Evaluation Of An Actuarial Risk Assessment Instrument, James Robert Johnson

Dissertations

As a result of years of legislation aimed at getting tough on crime, the United States now boasts some remarkable and unenviable statistics. Today, one in every 45 adults in the United States is under some form of community supervision (Pew Center, 2009). At a time when states are facing budget crises that have not been seen in decades, state leaders have an opportunity to both cut costs and improve public safety by focusing community supervision resources on higher-risk offenders through evidence-based practices (Austin, 2007; Latessa, 2003; MacKenzie, 2000; Pew Center, 2009).

Risk assessment is the critical first step …

Community Metrics And Trophic Dynamics In Tidal Creeks In An Anthropogenically Fragmented, Coastal Landscape, Michael Robert Lowe

Dissertations

Salt marsh landscapes are among the most anthropogenically altered ecosystems in the world. Urbanization (i.e., accumulation of impervious cover and man made structrues) of the coastal landscape can disrupt the delivery of numerous ecosystem services. Among the many services provided by salt marsh habitats, they serves as the primary habitats for distinct macroinfauna (i.e., benthic and epibenthic macrofauna) and nekton (i.e., fish and decapod crustaceans) assemblages. In this dissertation, I used a number of metrics to test the overarching hypothesis that coastal urbanization has negative consequences for salt marsh faunal assemblages. Chapter I uses a landscape ecology approach to show …

Risk-Appropriate Maternal Care: Identifying Risk Factors That Effect Maternal Outcome, Lucy R. Van Otterloo Phd, Msn, Rnc, Cns

Dissertations

Although maternal deaths are the most tragic of obstetric events it continues to be a rare event. Maternal morbidity, on the other hand, is increasing and poses a greater impact on the economic, psychological, and physical health of the woman and her family, yet it has not been the focus of measurement or research since there is no systematic collection of data available. As complications increase, the likelihood of adverse maternal outcomes such as longer postpartum stays due to the need for more extensive care will also increase. Nurses are being challenged to use their knowledge and skills to identify …

Gambling In San Diego County: A Case Study, Michael Kelley Phd

Dissertations

Legal gambling operations in the United States are based on public policy decisions. Although research has shown that gambling intensity levels are related to a number of individual disorders and impose significant economic costs on society, the data is incomplete. For example, while research indicates that certain demographic categories and proximity to places of gambling are predictors of high gambling rates, there is little information on the impact of economic conditions on gambling intensity, as well as the prevalence of such behavior in specific locations. With multiple gambling venues, a growing population of the demographic groups associated with higher gambling …

Work/Life Boundary Management In An Integrative Environment: A Study Of Residence Life Professionals Who Live At Their Place Of Work, Pressley Robinson Rankin Iv Phd

Dissertations

How individuals manage work/life boundaries when they live at the place they work, as opposed to working from home, is a gap in both work/life literature and in higher education literature. An obvious example from higher education is the resident life professional that lives in the residential facility that she or he oversees. Living in a residential facility creates challenges to boundary creation. The job requirements; pressures from students and staff; supervisor expectations, both spoken and unspoken; and the physical location of their home within the building creates a highly boundary integrative environment making the establishment of boundaries difficult. The …
