ROBUS-2 is the current version of the fault-tolerant computer communication system used by the Scalable Processor-Independent Design for Enhanced Reliability (SPIDER), a general-purpose fault-tolerant integrated modular architecture (IMA) developed at the NASA Langley Research Center. The major components of SPIDER include processing elements (PEs) to perform calculations, bus interface units …

Money Market Fund Reform Viewed Through A Systemic Risk Lens, Hilary J. Allen

Scholarly Articles in Law Reviews & Journals

I. INTRODUCTION

Money market funds ("MMFs") were first developed in the 1970s, and since that time, they have become increasingly popular as an alternative to deposit accounts. Since the financial crisis of September 2008, there has been much discussion about the systemic risks posed by alternatives to commercial banking products. One of the key themes of this discussion is whether the systemic importance of these alternative banking products justifies the imposition of heightened regulation and supervision. This article takes the view, after a comparison of deposit accounts and MMFs, that MMFs are systemically important. It then goes on to consider, …

Body Lice, Yersinia Pestis Orientalis, And Black Death, Mark Welford, Brian Bossak, Robert G. Mclean, Michael W. Fall, Michel Drancourt, Didier Raoult

United States Department of Agriculture Wildlife Services: Staff Publications

Letters exchanged on role of Y. pestis in European plague Black Death.

Our colleague and mentor David E. Davis researched and wrote in his retirement after years of research and reflection on rat ecology and rodent-borne diseases (3,4). Rattus rattus is commonly recognized as the vertebrate host of fl ea-borne plague that swept through Europe in the 1300s, killing >50% of the population. Davis believed this explanation did not fit what he knew of the ecologic requirements of fleas and black rats. He studied reports of archeologic excavations and reviewed poems, medieval bestiaries, and paintings and concluded that these rats …

Factors Influencing Long-Term Population Dynamics Of Pronghorn (Antilocapra Americana): Evidence Of An Allee Effect, Justin D. Hoffman, Hugh H. Genoways, Rachel R. Jones

University of Nebraska State Museum: Mammalogy Papers

Populations of pronghorn (Antilocapra americana) are subjected to multiple forms of density-dependent and density-independent regulation. Little is known about the combined effects of these variables across multiple populations throughout the landscape. The objectives of this study were to examine long-term trends in density and recruitment in pronghorn and to assess how different forms of regulation influence these trends. We used multiple density-dependent and density-independent explanatory variables in a model selection process to explain variation in pronghorn density and July fawn : doe ratios from 1955 to 1993 in 4 pronghorn management units in Nebraska. We also investigated levels …

The Elasticity Of Taxable Income During The 1990s: New Estimates And Sensitivity Analyses, Seth H. Giertz

Department of Economics: Faculty Publications

Over the past two decades, the elasticity of taxable income has emerged as the central parameter for assessing efficiency and revenue implications from changes to tax policy. This article estimates short- and longer-run responses of taxable (and gross) income to changes in tax rates using panels of U.S. tax returns for the 1990s. With the richest set of income controls, income-weighted elasticity estimates range from 0.19 to 0.33, depending on whether responses are measured over one- or three-year intervals. An alternative approach designed to capture delayed and anticipatory responses yields much larger estimates -- ranging from 0.43 over the short …

Synthesis And Characterization Of An Europium-Porphyrin Complex, Alejandro Blinder

All Capstone Projects

Photodynamic therapy (PDT) is a promising treatment that has continued to improve over the past thirty years when the first commercially approved photosensitizer (PS) was introduced. Although PDT has many successful applications, the terrifying number of new cancer cases reported each year makes scientists focus their efforts towards the development of new efficient PS for PDT. The biggest obstacle that prohibits PDT from becoming a more widely used therapy is the ineffective photosensitizers (PS) that are available on the market today. The purpose of this study was to evaluate the synthesized metal-porphyrin complex as a possible candidate as a PS. …

Model Citizen: Exploring The Portrayal Of Unconventional Models On Television Shows In Relation To Women's Self Image, Nicole Jenelle James

All Capstone Projects

According to the renowned Mayo Clinic, having a low self-image can lead people to suffer harmful: physical, emotional, and behavioral consequences. Much of women’s selfimage is reliant on comparing themselves to the media’s perception of beauty. In an effort to bolster American women’s self-esteem, a workshop is proposed to explore the relation between portrayal of unconventional models on television shows and women’s/viewer’s self-image.

Total Protein Determination Using Micro Plate Assay, Julie Ruffatti

All Capstone Projects

One of the largest challenges that food manufactures are facing today is the management of food allergens. Allergenic protein in trace amounts, part per million concentrations, will trigger a reaction in some individuals. Food manufacturers need to prevent allergen cross-contamination by performing adequate sanitation after production of an allergenic containing food. Allergen detection kits are used to determine if sufficient protein was removed from the equipment surfaces during sanitation. One kit on the market is the 3M™ Clean- Trace™ Surface Protein (Allergen) swab tests. The test qualitatively detects the presence of protein based on the biuret reaction and will yield …

Purification And Analysis Of Folate-Dye Conjugate, Dilipkumar Sakhiya

All Capstone Projects

The folate receptor has achieved great importance for use in targeted drug delivery and in vitro and in vivo diagnostic assays. The folate receptor (FR) is over-expressed on several cancer cell types and activated macrophages, but exists in relatively low abundance on the surface of non-cancerous tissue and non inflammatory cells. This unique attribute is the hallmark of folate-targeted methodologies allowing the diagnostic agent and/or drug to be ferried to the specific disease sites while preventing “off target” effects in normal tissues. Protein toxins, chemotherapeutic agents, radioimaging agents, magnetic resonance imaging (MRI) contrast agents liposomes with entrapped drugs, radiotherapeutic agents, …

Mathematics Self-Efficacy Of Community College Students In Developmental Mathematics Courses, David Walker Clutts

Doctoral Dissertations and Projects

Mathematics self-efficacy was defined as an individual's beliefs about how he or she would perform a specific math task or in a specific mathematics or related course. Mathematics self-efficacy was differentiated from self-esteem. Previous literature found self-efficacy in general and mathematics self-efficacy in particular to be significantly related to enrollment, retention, and completion. This study used the Mathematics Self-Efficacy Survey to investigate whether age, gender, developmental mathematics course, or developmental mathematics grade were significantly predictive of mathematics self-efficacy among developmental mathematics students course at a Kentucky community college. Multiple linear regression found that none of these variables were statistically significant …
