Designing A Comprehensive Framework For E-Government Implementation Success With A Special View Of The Case Of Saudi Arabia, Mohammed Alsaigh
Designing A Comprehensive Framework For E-Government Implementation Success With A Special View Of The Case Of Saudi Arabia, Mohammed Alsaigh
Theses and Dissertations
As a result of the increasing development in the field of Information Systems (IS) in the last decades, new concepts have appeared to serve specific requirements and needs (Smith 2010; Almarabeh and AbuAli 2010). E-government is one of these concepts, which appeared in 1993 (Silva 2006) to become one of the main tools for governments around the world to enhance the services provided by governments and their agencies (Atallah 2001). Investigating the literature shows that there are common issues in all e-government implementation projects which can be summarized as follows: 1) e-government implementation projects in their nature are vast, and …
My Identity, Kris Cho
My Identity, Kris Cho
Theses and Dissertations
My identity is the dominate theme in my works. As a Korean American, I am influenced by life experiences in both countries. These two vastly different cultures and experiences define me as an individual. I use references and symbolism from both cultures as elements in my painting, mixed media, and crafts. I have spent half of my life in Korea, my mother country, and the other half in America, my new homeland. Living as an American, my artworks keep me connected to my Korean roots. Creating artwork is my way to relay who I really am as a Korean American.
Adolescent Girls' Experience Of Binge And Loss Of Control Eating, Allison Palmberg
Adolescent Girls' Experience Of Binge And Loss Of Control Eating, Allison Palmberg
Theses and Dissertations
The current investigation used qualitative methodology to examine adolescent girls’ perceptions of control over their eating, as well as triggers, and consequences of binge and related eating behaviors. Focus groups were completed with 19 adolescent girls (aged 13-17, 58% African American, 41% White) who endorsed the behaviors. Responses to focus group questions were qualitatively analyzed using a grounded theory approach and constant comparison coding. Results reflected a fundamental lack of awareness of the loss of control (LOC) eating behaviors. Yet, the data did reflect a central theme of the need to affirm independence and autonomy through eating behaviors via three …
Elevating Endogenous Cannabinoids Reduces Opioid Withdrawal In Mice, Divya Ramesh
Elevating Endogenous Cannabinoids Reduces Opioid Withdrawal In Mice, Divya Ramesh
Theses and Dissertations
Delta9-tetrahydrocannbinol (THC), the primary active constituent of Cannabis sativa, has long been known to reduce opioid withdrawal symptoms. Although THC produces most of its pharmacological actions through the activation of CB1 and CB2 cannabinoid receptors, the role these receptors play in reducing opioid withdrawal symptoms remains unknown. The endogenous cannabinoids, N-arachidonoylethanolamine (anandamide; AEA) and 2-arachidonylglycerol (2-AG), activate both cannabinoid receptors, but are rapidly metabolized by fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), respectively. The objective of this dissertation was to test whether increasing AEA or 2-AG, via inhibition of their respective hydrolytic enzymes, reduces morphine withdrawal symptoms in …
Blood Glucose Monitoring And Metabolic Control In Youth With Type 1 Diabetes: Relation To Disease Care, Adrienne Borschuk
Blood Glucose Monitoring And Metabolic Control In Youth With Type 1 Diabetes: Relation To Disease Care, Adrienne Borschuk
Theses and Dissertations
Better disease care behaviors in youth with type 1 diabetes (T1D) are strongly related to better metabolic control (HbA1c). However, HbA1c results are only available, on average, every three months, and may not accurately capture intricacies of blood glucose fluctuations. Youth then must rely on blood glucose levels obtained throughout the day to determine which disease care behaviors to perform to maintain optimal metabolic control. Youth may have difficulty performing these disease care behaviors properly or consistently, which makes parental monitoring a crucial aspect of the diabetes regimen. Additionally, youth who experience frequent or severe hypoglycemia may develop a fear …
Comparison Of Steriplex™ Hc And Sodium Hypochlorite Cytotoxicity On Primary Human Gingival Fibroblasts, Jesse Harris
Comparison Of Steriplex™ Hc And Sodium Hypochlorite Cytotoxicity On Primary Human Gingival Fibroblasts, Jesse Harris
Theses and Dissertations
This study examined the cytotoxic effects of STERIPLEX™ HC (sBioMed, Orem, UT) and sodium hypochlorite (NaOCl) on human fibroblast cells in vitro. Fibroblasts exposed to various concentrations of NaOCl or STERIPLEX™ HC were visualized via light microscopy. Dilutions of either NaOCl or STERIPLEX™ HC that did not appear to disrupt the integrity of the cells were recorded for further analysis. Cells were then cultured and grown to confluence in five separate plates. A void was created down the middle of each plate. If the cells were viable, cellular confluence was seen. If nonviable, confluence of the cells did not occur. …
The Antimicrobial Effect Of Steriplex Hc In Comparison With Sodium Hypochlorite On Enterococcus Faecalis, Jonathan Coudron
The Antimicrobial Effect Of Steriplex Hc In Comparison With Sodium Hypochlorite On Enterococcus Faecalis, Jonathan Coudron
Theses and Dissertations
The study objective was to compare the antimicrobial activity of STERIPLEX™ HC with 5.25% sodium hypochlorite (NaOCl) at different dilutions (50%, 25%, 10%, 1%, 0.1%) and different time intervals (1, 3, 5 minutes) on Enterococcus faecalis. All data was analyzed using an ANOVA. The 50%, 25%, and 10% dilutions of both disinfectants reduced the colony forming unit (CFU) count to below the limit of detection (50 CFU/ml) after one minute. The 1% dilutions at each of the time intervals show NaOCl was significantly more effective than STERIPLEX™ HC (all Ps < .0001) in reducing the CFU/ml count. The 0.1% dilutions of NaOCl and STERIPLEX™ HC at 1 minute, were not different (P = 0.7808), while at 3 minutes and 5 minutes NaOCl was significantly more effective (P = 0.0098 and P < .0001, respectively).
Dynamics Of Substrate Interactions In Trna (M1g37) Methyltransferase: Implications For Drug Discovery, Maria Kiouppis Palesis
Dynamics Of Substrate Interactions In Trna (M1g37) Methyltransferase: Implications For Drug Discovery, Maria Kiouppis Palesis
Theses and Dissertations
The bacterial enzyme t-RNA (m1G37) methyltransferase (TrmD) is an ideal anti-microbial drug target since it is found in all eubacteria, serves an essential role during protein synthesis, and shares very little sequence or structural homology with its eukaryotic counterpart, Trm5. TrmD, a homodimeric protein, methylates the G37 nucleotide of tRNA using S-adenosyl-L-methionine (SAM) as the methyl donor and thus enables proper codon-anticodon alignment during translation. The two deeply buried binding sites for SAM seen in X-ray crystallography suggest that significant conformational changes must occur for substrate binding and catalytic turnover. Results from molecular dynamics simulations implicate a flexible loop region …
The Role Of Calcineurin In Dendritic Remodeling And Epileptogenesis In A Rat Model Of Traumatic Brain Injury, John Campbell
The Role Of Calcineurin In Dendritic Remodeling And Epileptogenesis In A Rat Model Of Traumatic Brain Injury, John Campbell
Theses and Dissertations
Traumatic brain injury (TBI), a leading cause of death and disability in the United States, causes potentially preventable damage in part through the dysregulation of neural calcium levels. This dysregulation likely affects the activity of the calcium-sensitive phosphatase, calcineurin, with serious implications for neural function. To test this possibility, the present study characterized the role of calcineurin in a rat model of brain trauma, the lateral fluid percussion injury model. Golgi-Cox histochemistry revealed an acute post-TBI loss and delayed overgrowth of dendritic spines on principal cortical cells. The spine loss appeared to require calcineurin activity, since administering a calcineurin inhibitor, …
The Role Of Positive Emotions In Health-Related Outcomes For Caregivers Of Veterans With Traumatic Brain Injury, Suzzette Chopin
The Role Of Positive Emotions In Health-Related Outcomes For Caregivers Of Veterans With Traumatic Brain Injury, Suzzette Chopin
Theses and Dissertations
The purpose of this study was to examine the relationship between both self-efficacy for caregiving and personal gain and several variables related to well-being in caregivers (N = 70) of veterans who sustained a traumatic brain injury (TBI). Specifically, the relationship between self-efficacy for caregiving and perceived physical health and the relationship between personal gain related to caregiving and depression and anxiety was examined. The relationship between caregiver personal gain and perceived care recipient behavior was also examined. Exploratory analyses considered kinship and racial/ethnic differences. This was a secondary analysis of pilot data collected at four Polytrauma Rehabilitation Centers (PRC) …
Determination Of Effective Training Methods To Learn A Laparoscopic Camera Navigation Task Under Stressful Environments, Devnath Vasudevan
Determination Of Effective Training Methods To Learn A Laparoscopic Camera Navigation Task Under Stressful Environments, Devnath Vasudevan
Theses and Dissertations
Stress in surgical environment is generally very high and can result in performance degradation increasing patient risk .Current Training systems for learning minimally invasive surgical skills do not consider the component of stress in their training model. In this study the focus was on developing alternative training models that would allow the learner to effectively perform minimally invasive skill under stress. Two alternate training methods: 1) Training under stress until high performance levels and 2) training until high performance and low cognitive load are achieved were considered for this study. The control group consisted of training under no stress and …

Spatial Distribution And Modulation Of Nitric Oxide Synthase In A Hypertensive Rat Model, Andrew Yannaccone
Spatial Distribution And Modulation Of Nitric Oxide Synthase In A Hypertensive Rat Model, Andrew Yannaccone
Theses and Dissertations
There are gaps in the fundamental understanding of the expression of nitric oxide synthases (NOS) in the microvasculature. We examined co-localization of NOS1 (nNOS), NOS2 (iNOS) and NOS3 (eNOS) in the spinotrapezius muscle of young adult male Wistar-Kyoto (WKY) and Spontaneously Hypertensive (SHR) rats according to fiber type using immunohistochemistry and brightfield microscopy. Data regarding fiber distribution, population and morphology data were collected. Alkaline phosphatase staining was used to determine capillary density and average number of capillaries around a fiber. Gel electrophoresis and Western blot techniques were used to compare myosin heavy chain (MHC) protein expression with fiber type population …
