Endomorphisms Of Abelian Groups With Small Algebraic Entropy, D. Dikranjan, Ketao Gong, P. Zanardo

Articles

We study the endomorphisms ϕ of abelian groups G having a “small” algebraic entropy h (where “small” usually means ). Using essentially elementary tools from linear algebra, we show that this study can be carried out in the group , where an automorphism ϕ with must have all eigenvalues in the open circle of radius 2, centered at 0 and ϕ must leave invariant a lattice in , i.e., be essentially an automorphism of . In particular, all eigenvalues of an automorphism ϕ with must be roots of unity. This is a particular case of a more general fact known …

On The Long Duration Of Till Sheet Construction : A Reassessment Of How Quaternary Grounding Line Translations Relate To Near-Surface Seismic-Stratigraphy Of Eastern Ross Sea, Antarctica, Sydney Grace Bowles

LSU Master's Theses

Previously acquired seismic surveys provide strong evidence that the post-Last Glacial Maximum (LGM) retreat of the West Antarctic Ice Sheet (WAIS) deposited a back-stepping succession of seismically-resolved grounding zone wedges (GZWs) in eastern Ross Sea. However, the chronology of WAIS retreat is debated. The conventional view is that three GZWs (Red, Brown, and Gray Units) were deposited since the LGM. An alternative view, based on recent radiocarbon dates, is that the youngest GZW (the Gray Unit) was deposited during the LGM. If correct, then the older GZWs (Red and Brown Units) were deposited prior to LGM. A recent study (Bart …

Atp-Induced Changes In F-Actin Expression Via P2x7, Taylor Hircock

Honors Program Theses

The purpose of this research project was to study the effects that extracellular ATP has on F-actin levels in cells containing the P2X7 purinergic receptor. MAC-T cells which express the receptor were exposed to various levels of ATP and stained to undergo flow cytometry. In this case, F-actin was labeled with 488 phalloidin which was able to be detected by the flow cytometer. This was done in conjuction with controls to show how ATP exposure affected Factin levels. Based on these results, the cytoskeletal changes taking place in the cell in response to ATP were able to be measured and …

The criteria gained through research can be used by teacher librarians to support and enhance the Latin collection in the Storm Lake Middle School library and others by creating guidelines literature should match. The questions asked in the study were: 1. What examples of Latino stereotyping are found in the Storm Lake collection and …

The Effects Of Stem Inquiry Practices On English Language Acquisition In A First Grade Classroom In Thailand, Rebecca J. Fuhrman-Petersen

Graduate Research Papers

This mixed-methods teacher action research project describes and interprets the effects of one American teacher's bicultural critical inquiry praxis on Thai first grade students' English language acquisition. The observations were conducted for one full academic year for 37 students enrolled in a bilingual, multicultural STEM pilot program. The results are based upon participant observation and narrative inquiry from a qualitative standpoint. However, quantitative methods were used to analyze 1) students' questioning, answering techniques and physical activities based on video recordings of STEM lesson activities; 2) students' growth in critical thinking skills as measured by their writing in relation to their …

Path Dependence In Tax Subsidies For Home Sales, Lily Kahng

Faculty Articles

At a time of looming fiscal crisis and virtual unanimity that tax expenditures must be curtailed, tax subsidies for homeownership stand out as among the most costly and unfair of these expenditures. As a result of tax subsidies for homeownership, the government foregoes billions of dollars in revenue each year, most of which benefits wealthy taxpayers. Moreover, subsidies for homeownership encourage overinvestment in housing and underinvestment in other business sectors, which impedes economic productivity, jobs creation and the ability of U.S. businesses to compete in the global marketplace.

Scholars and commentators have analyzed extensively the tax subsidy for home mortgage …

Evaluation Of The Live Release Rate Formula & Implementation: Example Analysis Of The Effects Of Mandatory Spay/Neuter Laws On Intake At Shelters Within Dallas, Tx, Amanda Laskoe

MPA/MPP/MPFM Capstone Projects

It is estimated that shelters spend $1 billion annually dealing with unwanted animals (Frank & Carlisle-Frank, 2007). Approximately six to eight million cats and dogs enter U.S. shelters each year, and three to four million of these animals are then euthanized (HSUS, 2009). These are staggering statistics, yet in the early nineties, euthanasia estimates ranged from seven to seventeen million dogs/cats annually (Frank & Carlisle-Frank, 2011). Such improvements have resulted from a greater understanding of, and resources being dedicated to, the issue. Unfortunately, the rate of decline for euthanasia has slowed because programs have not been accurately targeted toward animal …

Motivation In Athletes With And Without Autism Spectrum Disorder: Sq, Eq And Aq Relationships To Preferred Feedback, Julia C. Harreschou

Scripps Senior Theses

All athletes are driven by motivation, sources or reasons to push their bodies to their limits and continue to do so regularly. There have been several studies concerning motivation in typical athletes, and many regarding social motivation in people with High Functioning Autism (HFA), however most have been limited to children, and there have been no investigations into HFA athletes’ motivation. The current study looks into the role of social dimensions in athletics, and tests how one’s gender and placement on the Empathy Questionnaire (EQ), Systemizing Questionnaire (SQ), and on the Autism Questionnaire (AQ) affect intrinsic motivation in athletics. It …

Impact Of Pre-Columbian Agriculture, Climate Change, And Tectonic Activity Inferred From A 5,700-Year Paleolimnological Record From Lake Nicaragua, Jennifer E. Slate, Thomas C. Johnson, Ted C. Moore

Biology Faculty Publications

Lake Nicaragua, the largest lake in Central America, is a promising site for paleolimnological study of past climate change, tectonic and volcanic activity, and pre-Columbian agriculture in the region. It is near the northern limit of the Intertropical Convergence Zone (ITCZ), which brings the rainy season to the tropics, so effects of decreasing precipitation due to southern migration of the ITCZ through the Holocene should be observable. Because fault zones and an active volcano lie within the lake, the long-term impact of tectonic and volcanic activity can also be examined. Finally, the fertile volcanic soils near the lake may have …

A Comparative Analysis Of Point-Of-View Modeling For Industrial And Technology Education Courses, Petros J. Katsioloudis, Todd D. Fantz, Millie Jones

STEMPS Faculty Publications

(First paragraph): Enrollment in technology education at the college level has been declining (Isbell & Lovedahl, 1989; Volk, 1997; Daugherty, 1998; Hill, 1999; Ndahi & Ritz, 2003; Moye, 2009). It is essential for technology teacher educators to investigate ways to increase the enrollment in their programs, or the profession may fail to provide technology teachers in the future (Ndahi & Ritz, 2003). A solution that several institutions with technology education programs have adopted is the offering of the program via distance learning. Distance learning “allows participants to collapse time and space” (Cole, 2000, p. ix). According to Flowers (2003) technology …

Ricean Over Gaussian Modelling In Magnitude Fmri Analysis—Added Complexity With Negligible Practical Benefits, Daniel W. Adrian, Ranjan Maitra, Daniel B. Rowe

Mathematics, Statistics and Computer Science Faculty Research and Publications

It is well known that Gaussian modelling of functional magnetic resonance imaging (fMRI) magnitude time-course data, which are truly Rice distributed, constitutes an approximation, especially at low signal-to-noise ratios (SNRs). Based on this fact, previous work has argued that Rice-based activation tests show superior performance over their Gaussian-based counterparts at low SNRs and should be preferred in spite of the attendant additional computational and estimation burden. Here, we revisit these past studies and, after identifying and removing their underlying limiting assumptions and approximations, provide a more comprehensive comparison. Our experimental evaluations using Receiver Operating Characteristic (ROC) curve methodology show that …

Considerations In Designing Human-Computer Interfaces For Elderly People, Drew Williams, Mohammad Arif Ul Alam, Sheikh Iqbal Ahamed, William Chu

Mathematics, Statistics and Computer Science Faculty Research and Publications

As computing devices continue to become more heavily integrated into our lives, proper design of human-computer interfaces becomes a more important topic of discussion. Efficient and useful human-computer interfaces need to take into account the abilities of the humans who will be using such interfaces, and adapt to difficulties that different users may face – such as the difficulties that elderly users must deal with. Interfaces that allow for user-specific customization, while taking into account the multiple difficulties that older users might face, can assist the elderly in properly using these newer computing devices, and in doing so possibly achieving …

Ionization In Diesel Combustion For On-Board Diagnostics And Engine Control, Tamer Hassan Badawy

Wayne State University Dissertations

Diesel engines have been known for their high thermal efficiency and specific power output, but there is concern about engine-out NOx and particulate matter emissions. To meet the current emission standards, advanced diesel engines are fitted with electronically controlled fuel injection systems and sophisticated and expensive after-treatment devices. Further improvements are still needed to meet future goals in better fuel economy and the more stringent emission standards. In order to meet these goals, there is a need for the control of the combustion process to reduce engine-out emissions in real-time and reduce the demand on the after-treatment devices. This requires …

Managing Soil Microbial Communities With Organic Amendments To Promote Soil Aggregate Formation And Plant Health, Shawn T. Lucas

Theses and Dissertations--Plant and Soil Sciences

The effects of managing soil with organic amendments were examined with respect to soil microbial community dynamics, macroaggregate formation, and plant physio-genetic responses. The objective was to examine the possibility of managing soil microbial communities via soil management, such that the microbial community would provide agronomic benefits. In part one of this research, effects of three amendments (hairy vetch residue, manure, compost) on soil chemical and microbial properties were examined relative to formation of large macroaggregates in three different soils. Vetch and manure promoted fungal proliferation (measured via two biomarkers: fatty acid methyl ester 18:2ω6c and ergosterol) and also stimulated …

Transformations, Bioavailability And Toxicity Of Manufactured Zno Nanomaterials In Wastewter, Sewwandi Rathnayake

Theses and Dissertations--Plant and Soil Sciences

In order to properly evaluate the ecological and human health risks of ZnO Manufactured nanomaterials (MNMs) released to the environment, it is critical to understand the likely transformation products in the wastewater treatment process and in soils receiving biosolids. To address this critical knowledge gap, we examined the transformation reactions of 30 nm ZnO MNMs in single component and multi-component systems, with phosphate and natural organic matter (NOM). We also assessed the influence of nano ZnO transformation on the bioavailability, and toxicity of ZnO transformation products to Triticum aestivum. The data revealed that ZnO MNMs react with phosphate at …

Influence Of Riparian Buffer Management Strategies On Soil Properties, Amanda A. Gumbert

Theses and Dissertations--Plant and Soil Sciences

The Kentucky Division of Water indicates that agriculture is responsible for 55% of the Commonwealth’s assessed streams not supporting their designated uses. Riparian buffers reduce nonpoint source pollution in agroecosystems by storing and cycling nutrients, stabilizing streambanks, increasing infiltration, and storing water. Specific information regarding riparian buffer management is needed for land managers to maximize buffer effectiveness at reducing agricultural contaminants impairing water quality.

Baseline soil properties (texture, pH, C and nutrients) of the riparian buffer surrounding a tributary of Cane Run Creek in Fayette County, KY were characterized prior to imposing three mowing regimes (intense, moderate, and no mow …

Mapping And Decomposing Scale-Dependent Soil Moisture Variability Within An Inner Bluegrass Landscape, Carla Landrum

Theses and Dissertations--Plant and Soil Sciences

There is a shared desire among public and private sectors to make more reliable predictions, accurate mapping, and appropriate scaling of soil moisture and associated parameters across landscapes. A discrepancy often exists between the scale at which soil hydrologic properties are measured and the scale at which they are modeled for management purposes. Moreover, little is known about the relative importance of hydrologic modeling parameters as soil moisture fluctuates with time. More research is needed to establish which observation scales in space and time are optimal for managing soil moisture variation over large spatial extents and how these scales are …

Risk Perception In Cardiovascular Disease, Michelle Ellen Block

Dissertations

Cardiovascular disease (CVD) remains among the leading causes of death in the United States despite widespread knowledge about risk factors as well as effective primary prevention strategies. Risk perception is a complex phenomenon that plays an important role in how persons view disease and ultimately how they make health behavior choices. This study is supported by the knowledge that few studies have examined how persons perceive cardiovascular risk or the variables thought to contribute to the formation of risk perception.

Purpose: The purpose of this study was to examine how accurately persons perceive personal risk for cardiovascular disease and identify …

Most avalanche fatalities in Turkey have occurred in Bitlis Province. The scope of this research was to identify the avalanche hazard area of that province, using geographical information system (GIS) based multicriteria decision analysis (MCDA) and to evaluate it by means of sensitivity and accuracy analysis. The model consists of 5 GIS layers: elevation, slope, aspect, vegetation density, and land use. The hazard model is obtained by using a comparison matrix where all identified criteria of GIS layers are compared against each other. The acceptability of the model was determined using historical events. All of these events plotted over the …

Hedge Fund Governance, Houman B. Shadab

Articles & Chapters

This Article provides the first comprehensive scholarly analysis of the internal governance of hedge funds. Hedge fund governance consists of the funds' underlying legal regime and the practices they adopt in response to lacking permanent capital and to reduce agency costs. Hedge fund governance is important because better governance can improve investor returns and help managers raise and retain capital. I argue that hedge fund governance is best understood as a type of responsive managerialism. It is a type of managerialism because applicable law and contracting structures give managers uniquely wide-ranging control over the fund and its operations. Hedge fund …

Orientation Invariant Ecg-Based Stethoscope Tracking For Heart Auscultation Training On Augmented Standardized Patients, Nahom Kidane, Salim Chemlal, Jiang Li, Frederic D. Mckenzie, Tom Hubbard

Computational Modeling & Simulation Engineering Faculty Publications

Auscultation, the act of listening to the heart and lung sounds, can reveal substantial information about patients’ health and other cardiac-related problems; therefore, competent training can be a key for accurate and reliable diagnosis. Standardized patients (SPs), who are healthy individuals trained to portray real patients, have been extensively used for such training and other medical teaching techniques; however, the range of symptoms and conditions they can simulate remains limited since they are only patient actors. In this work, we describe a novel tracking method for placing virtual symptoms in correct auscultation areas based on recorded ECG signals with various …
