Rhode Island School Terrorist Attack Preparedness, Michael Dube

Doctoral Dissertations and Projects

This study examined the state of safety and terrorist attack preparedness in Rhode Island Schools as determined by Rhode Island school leader perceptions. The study is descriptive in nature as it gathers data to describe a particular event or situation. Using a researcher generated survey based on terrorist preparedness guidelines and suggestions in part from the Department of Homeland Security (2007), U.S. Department of Education (2007), National School Safety Center (2005), and National Association of School Resource Officers (2005), Rhode Island school administrators were asked to use a Likert rating scale to indicate levels of agreement with accepted terrorist preparedness …

The Effects Of The Family On Student Achievement: A Comparative Study Of Traditional Nontraditional Families, Melinda Fonteboa

Doctoral Dissertations and Projects

The purpose of this quantitative, causal-comparative study was to test the interactive framework of social cognitive theory, attachment theory, and the theory of moral absolutism by comparing the academic achievement of over 200 high school seniors (as measured by the Georgia High School Graduation Test; GHSGT) based on the structures of their families. The independent variable of family structure was initially classified as either nontraditional or traditional. A nontraditional family was defined, for the purposes of this study, as any family that is not comprised in its entirety by two biological parents (or adoptive parents from birth), one male and …

Do Students Using Electronic Books Display Different Reading Comprehension And Motivation Levels Than Students Using Traditional Print Books?, Casey Wells

Doctoral Dissertations and Projects

The effect of electronic books on the reading comprehension of middle and high school students was examined using an experimental posttest-only control-group design. A convenience sample of 140 randomly assigned middle and high school English students at an independent school in eastern North Carolina participated. Half of the students used passages from text read on tablets while half utilized traditional print text passages. Data was collected during one class period in which the reading comprehension section of the Gates-MacGinitie Reading Tests®, a 35 minute test containing 48 questions, was administered. Reading comprehension data was analyzed using an independent t-test. The …

Estimating Dynamic Discrete Choice Models Of Product Differentiation: An Application To Medicare Part D With Switching Costs, Daniel P. Miller, Jungwon Yeo

Research Collection School Of Economics

This paper proposes an algorithm to estimate dynamic discrete choice models using aggregate market share data. The algorithm achieves a computational advantage by decomposing the complicated mapping between market shares and utility flows into two simpler ones. The first maps observed market shares to mean choice specific values, and the second then maps to mean utility flows. In the application, we estimate switching costs in the Medicare Part D market. Our results indicate a large switching cost of around $1,700, which implies an average welfare loss of $480 as enrollees choose to remain in sub-optimal plans to avoid switching costs.

Anaesthetic Management Of A Young Patient With Homocystinuria, Ali Asghar, Faiza Mazhar Ali

Department of Anaesthesia

Homocystinuria is a rare autosomal recessive genetic disease. It is caused by a deficiency in cystathionine-b-synthase leading to a defect in methionine metabolism. High levels of plasma homocysteine are associated with vascular injury via mechanisms of oxidative damage, vascular smooth muscle proliferation, promotion of platelet activation and aggregation,and disruption of normal procoagulant-anticoagulant balance favouring thrombosis. This is a case of 8 years old boy, a known case of homocystinuria, who was scheduled for bilateral lensectomy and intraocular lens placement. The major anaesthetic considerations include the development of thromboembolism, need to avoid nitrous oxide in balanced anaesthesia regimen and hypoglycaemia.

Colorectal Cancer Tumoral And Nodal Staging : Comparison Between Ct Findings And Pathological Findings, J Busaman, B Chaopathomkul, N Wisedopas, L. Vajragupta

Chulalongkorn Medical Journal

Background and Rationale : Colorectal cancer is a common malignancy of the gastrointestinal tract. In Thailand, colorectal cancer is the third most common cancer in males and fifth most common in females. Incidence rate of colorectal cancer has been rising in Thailand. Pathologic staging is the gold standard for colorectal cancer. However, it is followed by post-operative procedure. Computed tomography (CT) is noninvasive and preoperative assessment. Preoperative CT is useful for planning therapy by which local extension of the tumor into the adjacent organs or distant metastases are demonstrated. Differentiation between T2 and T3 colon cancer is important for consideration …

International Activity And Domestic Law, Adam I. Muchmore

Faculty Scholarship

This invited essay explores the ways States use their domestic laws to regulate activities that cross national borders. Domestic-law enforcement decisions play an underappreciated role in the development of international regulatory policy, particularly in situations where the enforcing State's power to apply its law extraterritorially is not contested. Collective action problems suggest there will be an undersupply of enforcement decisions that promote global welfare and an oversupply of enforcement decisions that promote national welfare. These collective action problems may be mitigated in part by government networks and other forms of regulatory cooperation.

Decrease In Central Venous Catheter Placement And Complications Due To Utilization Of Ultrasound-Guided Peripheral Intravenous Catheters, Arthur K Au, Masashi Rotte, Robert Grzybowski, Bon Ku, Jason M. Fields

Department of Emergency Medicine Faculty Papers

Poster presented at: American College of Emergency Physicians (ACEP) conference.

Introduction: -Up to 40% of ED visits include diagnostic blood tests and 26% result in administration of IV fluids necessitating successful peripheral intravenous (IV) catheter placement.1 -There is a subset of patients with difficult IV access (DIVA) in which traditional cannulation methods are unsuccessful resulting in central venous cannulation (CVC). -CVCs have a 5-15 percent complication rate2 and attributable costs per CVC related infection have been estimated at $34,508-$56,000.3 -Ultrasound-guided peripheral IV catheters (USGPIVs) provide a method of potentially decreasing the need for CVC placement, however due to poor durability …

The Tax Expenditure Budget Is A Zombie Accountant, Steven A. Dean

Faculty Scholarship

Like a student blocking his access to the internet to help him study, governments across the globe rely on commitment devices to generate fiscal discipline. From the collapse of the Congressional Supercommittee in the United States to the near-cataclysmic failure of a mechanism designed to prevent the European Union debt crisis, the evidence suggests that faith in such commitment devices is misplaced. This Article focuses on one such device that stubbornly refuses to stay dead: the tax expenditure budget. Created to guard against abuse by publicizing the costs of tax subsidies then resurrected as a bean counter, the tax expenditure …

Truths We Must Tell Ourselves To Manage Climate Change, Robert H. Socolow

Vanderbilt Law Review

In 1958, Charles David Keeling began measuring the concentration of carbon dioxide (C02) in the atmosphere, at a site 11,000 feet above sea level near the top of Mauna Loa on the "big island" of Hawaii. The time series of monthly averages, the "Keeling Curve," is the iconic figure of climate change (see Figure 1). The curve oscillates and rises. The annual oscillations (whose details are seen in the Figure's inset) are the consequences of the seasonal breathing of the northern-hemisphere forests, which remove C02 from the atmosphere during their growing season and return C02 to the atmosphere as their …

Sustainable Consumption, Energy Policy, And Individual Well-Being, Daniel A. Farber

Vanderbilt Law Review

The United States is an exceptional place in many ways, not least in its consumption. The United States consumes a disproportionate share of the world's energy and resources, with a correspondingly large environmental footprint. At present, although we have been successful in creating economic wealth, well-being has lagged behind. Could the United States shift to a more sustainable path? Would that require an unacceptable sacrifice of social welfare? This Article argues that a shift really is possible, and that many of the steps to sustainability would actually make people better off even apart from their environmental benefits.

At present, we …

Can We Regulate Our Way To Energy Efficiency? Product Standards As Climate Policy, Noah M. Sachs

Vanderbilt Law Review

Alternative energy supplies get most of the attention in the climate change debate, but reducing energy demand should be the dominant strategy for cutting global greenhouse gas emissions. Dozens of technical studies have concluded that improving the efficiency of automobiles, furnaces, motors, consumer electronics, lighting, air conditioners, and other energy-using products is the cheapest and fastest way to achieve dramatic reductions in greenhouse gas emissions.' In fact, avoiding catastrophic global heating largely depends on how fast energy efficient technology can be deployed over the next few decades.

Energy efficiency can be promoted through multiple policies, such as energy taxes, a …

Hydro Law And The Future Of Hydroelectric Power Generation In The United States, Dan Tarlock

Vanderbilt Law Review

Hydroelectric energy ("hydro") is the oldest major source of noncarbon, renewable energy in the United States. For three reasons, increased hydro generation should be a major element of any national climate change and energy-security policy designed to promote the greater use of renewables to help the country transition to the production of sustainable, i.e., noncarbon-based, energy. First, hydro is relatively clean because it does not cause air pollution or substantial greenhouse gas emissions.' Second, hydro is relatively reliable. Third, hydro can help wean the United States from its dependence on imported and often politically unstable hydrocarbon sources of energy, because …

Sickle Cell Pain: A Critical Reappraisal., Samir K. Ballas, Kalpna Gupta, Patricia Adams-Graves

Department of Medicine Faculty Papers

Sickle cell pain includes 3 types: acute recurrent painful crises, chronic pain syndromes, and neuropathic pain. The acute painful crisis is the hallmark of the disease and the most common cause of hospitalization and treatment in the emergency department. It evolves through 4 phases: prodromal, initial, established, and resolving. Each acute painful episode is associated with inflammation that worsens with recurrent episodes, often culminating in serious complications and organ damage, such as acute chest syndrome, multiorgan failure, and sudden death. Three pathophysiologic events operate in unison during the prodromal phase of the crisis: vaso-occlusion, inflammation, and nociception. Aborting the acute …

Bandemia With Normal White Blood Cell Counts Associated With Infection., Marci Drees, Narrani Kanapathippillai, Marc T Zubrow

Department of Medicine Faculty Papers

OBJECTIVE: Measuring immature white blood cell forms ("bands") has been considered clinically unnecessary. We performed this study to determine whether elevated band counts, with normal total white blood cells on admission, were associated with infection or in-hospital death.

METHODS: We performed a retrospective cohort study including all patients admitted to the Christiana Care Health System 2-hospital, 1100-bed community-based academic health system in 2009 with normal white blood cells (3800-10,800 per mm(3)) on admission who had manual differentials performed. We defined our band groups as normal (≤10% bands and other immature cells), moderate (11%-19%), or high (≥20%). Via chart review, we …

Differential Effects Of The Hydrophobic Surfactant Proteins On The Formation Of Inverse Bicontinuous Cubic Phases, Mariya Chavarha, Ryan W. Loney, Kamlesh Kumar, Shankar B. Rananavare, Stephen B. Hall

Chemistry Faculty Publications and Presentations

Prior studies have shown that the biological mixture of the two hydrophobic surfactant proteins, SP-B and SP-C, produces faster adsorption of the surfactant lipids to an air/water interface, and that they induce 1-palmitoyl-2-oleoyl phosphatidylethanolamine (POPE) to form inverse bicontinuous cubic phases. SP-B has a much greater effect than SP-C on adsorption. If the two proteins induce formation of the bicontinuous structures and faster adsorption by similar mechanisms, then they should also have differential ability to form the cubic phases. To test this hypothesis, we measured small angle X-ray scattering on the individual proteins combined with POPE. SP-B replicated the doserelated …

Thiol Reactive Probes And Chemosensors, Robert M. Strongin, Lovemore Hakuna, Hanjing Peng, Weixuan Chen, Yunfeng Cheng, Binghe Wang

Chemistry Faculty Publications and Presentations

Thiols are important molecules in the environment and in biological processes. Cysteine (Cys), homocysteine (Hcy), glutathione (GSH) and hydrogen sulfide (H2S) play critical roles in a variety of physiological and pathological processes. The selective detection of thiols using reaction-based probes and sensors is very important in basic research and in disease diagnosis. This review focuses on the design of fluorescent and colorimetric probes and sensors for thiol detection. Thiol detection methods include probes and labeling agents based on nucleophilic addition and substitution, Michael addition, disulfide bond or Se-N bond cleavage, metal-sulfur interactions and more. Probes for H2S are based on …

The Transcription Factor Gli1 Mediates Tgfb1 Driven Emt In Hepatocellular Carcinoma Via A Snai1-Dependent Mechanism, Sherine F. Elsawa, Xin Zheng, Natalia B. Rumie Vittar, Xiaohong Gai, Maite G. Fernandez-Barrena, Catherine D. Moser, Chunling Hu, Luciana L. Almada, Angela L. Mccleary-Wheeler, Anne M. Vrabel, Abdirashid M. Shire, Andrea Comba, Snorri S. Thorgeirsson, Youngsoo Kim, Qingguang Liu, Martin E. Fernandez-Zapico, Lewis R. Roberts

Faculty Articles, Papers, and Other Scholarship

The role of the epithelial-to-mesenchymal transition (EMT) during hepatocellular carcinoma (HCC) progression is well established, however the regulatory mechanisms modulating this phenomenon remain unclear. Here, we demonstrate that transcription factor glioma-associated oncogene 1 (GLI1) modulates EMT through direct up-regulation of SNAI1 and serves as a downstream effector of the transforming growth factor-b1 (TGFb1) pathway, a well-known regulator of EMT in cancer cells. Overexpression of GLI1 increased proliferation, viability, migration, invasion, and colony formation by HCC cells. Conversely, GLI1 knockdown led to a decrease in all the above-mentioned cancer-associated phenotypes in HCC cells. Further analysis of GLI1 regulated cellular functions showed …

Analysis Of Travel Time Reliability For Freight Corridors Connecting The Pacific Northwest, Miguel A. Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

A new methodology and algorithms were developed to combine diverse data sources and to estimate the impacts of recurrent and non-recurrent congestion on freight movements’ reliability and delays, costs, and emissions. The results suggest that traditional traffic sensor data tend to underestimate the impacts of congestion on commercial vehicles travel times and variability. This research also shows that congestion is not only detrimental for carriers and shippers costs but also for the planet due to major increases in GHG emissions and for the local community due to large increases in NOx, PM, and other harmful pollutants.

The methodologies developed throughout …

Health Behaviour Changes After Diagnosis Of Chronic Illness Among Canadians Aged 50 Or Older, Jason T. Newsom, Nathalie Huguet, Pamela L. Ramage-Morin, Michael Joseph Mccarthy, Julie Bernier, Mark S. Kaplan, Bentson H. Mcfarland

Community Health Faculty Publications and Presentations

Changes in health behaviors (smoking, physical activity, alcohol consumption, and fruit and vegetable consumption) after diagnosis of chronic health conditions (heart disease, cancer, stroke, respiratory disease, and diabetes) were examined among Canadians aged 50 or older. Results from 12 years of longitudinal data from the Canadian National Population Health Survey indicated relatively modest changes in behavior. Although significant decreases in smoking were observed among all groups except those with respiratory disease, at least 75% of smokers did not quit. No significant changes emerged in the percentage meeting physical activity recommendations, except those with diabetes, or in excessive alcohol consumption, except …
