Effects Of Ectoparasites And Reproductive Class On Roost-Switching And Foraging Behavior Of Indiana Bats (Myotis Sodalis), Nicholas S. Gikas

All-Inclusive List of Electronic Theses and Dissertations

Ectoparasites of bats have been known to cause harm to their hosts and to affect roost-switching. Little research exists on effects ectoparasites may have on roosting and foraging behavior of the federally endangered Indiana bat (Myotis sodalis). From 2008 through 2010, I collected ectoparasite data and documented roost-switching and foraging behavior of Indiana bats on habitat restoration lands owned by the Indianapolis International Airport (IND) in central Indiana. I tested for differences in roosting and foraging behavior between bats with varying ectoparasite loads, and for differences in ectoparasite load, roost-switching frequency, and foraging behavior between different reproductive classes of Indiana …

An Automated Data Analysis Tool For Livestock Market Data, Galen S. Williams, Kellie Curry Raper

Journal of Extension

This article describes an automated data analysis tool that allows Oklahoma Cooperative Extension Service educators to disseminate results in a timely manner. Primary data collected at Oklahoma Quality Beef Network (OQBN) certified calf auctions across the state results in a large amount of data per sale site. Sale summaries for an individual sale need to be quickly dispensed to program coordinators, auction barn owners, and program participants. Data entered into a Microsoft Excel spreadsheet at sales is summarized using Excel database commands. A link to Microsoft Publisher then generates the sale summary for an individual OQBN sale.

Escape From Competition: Neighbors Reduce Centaurea Stoebe Performance At Home But Not Away, Ragan M. Callaway, Lauren P. Waller, Alecu Diaconu, Robert Pal, Alexandra R. Collins, Heingz Mueller-Schaerer, John L. Maron

Biological Sciences Faculty Publications

The greater abundance of some exotic plants in their nonnative ranges might be explained in part by biogeographic differences in the strength of competition, but these competitive effects have not been experimentally examined in the field. We compared the effects of neighbors on the growth and reproduction of spotted knapweed (Centaurea stoebe) in Europe, where it is native, and in Montana, where it is invasive. There were strong negative competitive effects of neighboring vegetation on C. stoebe growth and reproduction in Europe. In contrast, identical experiments in Montana resulted in insignificant impacts on C. stoebe. Although the …

Recent Rates Of Forest Harvest And Conversion In North America, Jeffrey G. Masek, Warren B. Cohen, Donald Leckie, Michael A. Wulder, Rodrigo Vargas, Ben De Jong, S. P. Healey, Beverly Law, Richard Birdsey, R. A. Houghton, David J. Mildrexler, Samuel Goward, W. Brad Smith

Numerical Terradynamic Simulation Group Publications

Incorporating ecological disturbance into biogeochemical models is critical for estimating current and future carbon stocks and fluxes. In particular, anthropogenic disturbances, such as forest conversion and wood harvest, strongly affect forest carbon dynamics within North America. This paper summarizes recent (2000–2008) rates of extraction, including both conversion and harvest, derived from national forest inventories for North America (the United States, Canada, and Mexico). During the 2000s, 6.1 million ha/yr were affected by harvest, another 1.0 million ha/yr were converted to other land uses through gross deforestation, and 0.4 million ha/yr were degraded. Thus about 1.0% of North America's forests experienced …

High-Resolution Study Of Layering Within The Percolation And Soaked Facies Of The Greenland Ice Sheet, Joel Brown, Joel T. Harper, W. Tad Pfeffer, Neil Humphrey, John H. Bradford

Geosciences Faculty Publications

Within the percolation and soaked facies of the Greenland ice sheet, the relationship between radar-derived internal reflection horizons and the layered structure of the firm column is unclear. We conducted two small-scale ground-penetrating radar (GPR) surveys in conjunction with 10 m firm cores that we colleced within the percolation and soaked facies of the Greenland ice sheet. The two surveys were separated by the distance of about 50 km and about 340 m of elevation leading to about 40 days of difference in the duration of average annual melt. At the higher site (about 1997 ma.s.l.), which receives less melt, …

Genetic Monitoring For Managers: A New Online Resource, Jeffrey Brian Stetz, Katherine Kendall, Christina D. Vojta, Genetic Monitoring (Gem) Working Group

Wildlife Biology Faculty Publications

Monitoring our natural resources will increasingly rely on genetic tools in order to understand and respond to invasive species, habitat degradation, fragmentation, disease, or climate-related changes. In recent years, the rapidly evolving field of genetic monitoring has seen explosive growth in sampling methods, genetic markers, and analytical approaches designed to estimate a wide range of parameters from connectivity to population growth rates. Some of these methods have taken root and now dominate particular aspects of population assessment and monitoring, whereas others have seen less success in real-world applications. To aid managers and researchers with limited genetics experience, we developed a …

Entrepreneurial Illegality: Empirical Examination Of The Effects Of Bribery And Tax Evasion On Firm Performance, Nnaoke Ufere

Student Scholarship

We examined the nexus of entrepreneurial illegality and firm performance in an emerging market by investigating the extent to which antecedent conditions such as economic constraints, bureaucratic demands, institutional pressures and entrepreneurial agency increase the supply of illegal opportunities exploited by entrepreneurs for private gains. Using 2009 World Bank Enterprise Survey data of 2599 small and medium-sized entrepreneurial enterprises (SMEEs) in Nigeria, we demonstrate that illegal entrepreneurial behaviors in developing markets--specifically bribery and tax evasion--affect firm performance measured by sales and employment growth. Results show that illegal opportunities significantly increase with bureaucratic and regulatory intervention in entrepreneurial activities, suggesting current …

Maternal Separation Affects Dopamine Transporter Function In The Spontaneously Hypertensive Rat: An In Vivo Electrochemical Study, Jacqueline S. Womersley, Jennifer H. Hsieh, Lauriston A. Kellaway, Greg A. Gerhardt, Vivienne A. Russell

Neuroscience Faculty Publications

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder characterised by symptoms of inattention, impulsivity and hyperactivity. The spontaneously hypertensive rat (SHR) is a well-characterised model of this disorder and has been shown to exhibit dopamine dysregulation, one of the hypothesised causes of ADHD. Since stress experienced in the early stages of life can have long-lasting effects on behaviour, it was considered that early life stress may alter development of the dopaminergic system and thereby contribute to the behavioural characteristics of SHR. It was hypothesized that maternal separation would alter dopamine regulation by the transporter (DAT) in ways that distinguish SHR …

Pluralism And Property, Gregory S. Alexander

Cornell Law Faculty Publications

Welfarism is no longer the only game in the town of property theory. In the last several years a number of property scholars have begun developing various versions of a general vision of property and ownership that, although consistent with welfarism in some respects, purports to provide an alternative to the still-dominant welfarist account. This alternative proceeds under different labels, including “virtue theory” and “progressive,” but for convenience purposes let us call them collectively “social obligation” theories. For what they have in common is a desire to correct the common but mistaken notion that ownership is solely about rights. These …

Property's Memories, Eduardo M. Peñalver

Cornell Law Faculty Publications

This short essay, presented at Fordham's conference on the social functions of property (and in an earlier form at a conference on law and memory at USC), explores the relationship between property and memory. It distinguishes between property as the object of memory ("memory of property") and property as a medium of memory ("memory in property"). With respect to both kinds of memory, the common law expresses a great deal of ambivalence towards memory. Unlimited memory is no less dangerous to a system of property than it is to an individual’s ability to think. Recent reforms of adverse possession, the …

Children’S Independent Mobility : And The Mobile Phone: 8 To 12 Year Olds, Catherine Underwood

Program monitoring and evaluation

Children who know how to use a mobile phone, as opposed to those who don’t, are more likely to move about their neighbourhood without adult supervision, research from the Australian Council for Educational Research (ACER) suggests. The study, by ACER Research Fellow Ms Catherine Underwood, examined the extent to which knowing how to use a mobile phone is correlated with children’s physical activity and ability to move through their neighbourhood without adult supervision, also known as independent mobility. More than 800 Victorian primary school children aged between 8 and 12 years participated in the research, of which 84 per cent …

Novel Amino Acid Transporter-Targeted Radiotracers For Breast Cancer Imaging, Fanlin Kong

Dissertations and Theses (Open Access)

Breast cancer is the most common malignancy among women in the world. Its 5-year survival rate ranges from 23.4% in patients with stage IV to 98% in stage I disease, highlighting the importance of early detection and diagnosis. ¹⁸F-2-Fluoro-2-deoxy-glucose (¹⁸F-FDG), using positron emission tomography (PET), is the most common functional imaging tool for breast cancer diagnosis currently. Unfortunately, ¹⁸F-FDG-PET has several limitations such as poorly differentiating tumor tissues from inflammatory and normal brain tissues. Therefore, ¹⁸F-labeled amino acid-based radiotracers have been reported as an alternative, which is based on the fact that tumor cells uptake …

Evaluation Of Deformable Image Registration For Improved 4d Ct-Derived Ventilation For Image Guided Radiotherapy, Richard Castillo

Dissertations and Theses (Open Access)

Recent treatment planning studies have demonstrated the use of physiologic images in radiation therapy treatment planning to identify regions for functional avoidance. This image-guided radiotherapy (IGRT) strategy may reduce the injury and/or functional loss following thoracic radiotherapy. 4D computed tomography (CT), developed for radiotherapy treatment planning, is a relatively new imaging technique that allows the acquisition of a time-varying sequence of 3D CT images of the patient's lungs through the respiratory cycle. Guerrero et al. developed a method to calculate ventilation imaging from 4D CT, which is potentially better suited and more broadly available for IGRT than the current standard …

Purinergic Signaling Regulates Filopodia-Induced Zippering, Jessica Lynn Bowser

Dissertations and Theses (Open Access)

The molecular mechanisms that mediate endometrial cancer invasion and metastasis remain poorly understood. This is a significant clinical problem, as there is no definitive cure for metastatic disease. The purinergic pathway’s generation of adenosine and its activation of the adenosine receptor A2B (A2BR) induces cell-cell adhesion to promote barrier function. This barrier function is known to be important in maintaining homeostasis during hypoxia, trauma, and sepsis. Loss of this epithelial barrier function provides a considerable advantage for carcinoma progression, as loss of cell-cell adhesions supports proliferation, aberrant signaling, epithelial-to-mesenchymal transition, invasion, and metastasis. The present work provides strong evidence that …

Entry-Level Student Affairs Administrators' Attitudes Toward Mental Illness In College Students., Jennifer A. Schum

Electronic Theses and Dissertations

Calls for universities to better serve college students with mental illness have been growing. While a considerable literature base supports Corrigan's (2004) Social Cognitive Model of Mental Illness Stigma and the complex relationship among stereotypes, prejudice, and discrimination, limited research has been conducted examining university administrators on attitudes toward and knowledge of mental illness in college students. Participants of the current study were 206 entry-level student affairs professionals who completed an online, modified version of Becker, Martin, Wajeeh, Ward, and Shern's (2002) Mental Illness Awareness Survey. Simultaneous regression was used to determine the significance of seven demographic variables (gender, age, …

Efficacy Of Child Parent Relationship Therapy For Caregivers Of Children With Attachment Problems., Margaret Sergeant

A Masterable Past? Swiss Historical Memory Of World War Ii, Sara Ormes

Senior Honors Theses

After World War II, every country that had been touched by or involved in the war had to come to terms with its past. In the case of Switzerland, the Swiss government, the army and some of the country’s leadership established a strong official historical memory of the war, portraying Switzerland as a neutral, benevolent and well-fortified country that remained innocent and untouched by the war.

From the 1960s onwards, Swiss artists and intellectuals challenged these myths by presenting alternative views of the Swiss past in their work. Beginning in the 1970s, Swiss historians published an increasing amount of scholarly …

The Ripple Effect, Ashley J. Hunter

Senior Honors Theses

In 2006, Steven Oakley, an eighteen-year-old high school senior from Pennsylvania, is bribed by his father to go on a volunteer trip to hurricane-ravaged New Orleans, Louisiana. During his time, he meets a broken family whose experiences change Steven’s perspective on his own privileged life.

The Impact Of Ambrosia Trifida (Giant Ragweed) On Native Prairie Species In An Early Prairie Restoration Project, Krisztian Megyeri

Senior Honors Theses

As the ecological importance of prairies is becoming more recognized, the number of prairie restoration projects is increasing worldwide. One of the major challenges in restoring any disturbed ecosystem is the successful establishment of native species at the expensive of invasive species. While some weedy species are gradually replaced as other, more desired, species become established, there are invasive species that, due to their level of dominance, may out-compete native species indefinitely. The objectives of this study were 1) to quantify the impact of Ambrosia trifida (giant ragweed) on the plant community of a newsly established prairie, 2) to assess …

Comparing Cropping System Productivity Between Fixed Rotations And A Flexible Fallow System Using Modeling And Historical Weather Data In The Semi-Arid Central Great Plains, Juan Jose Miceli-Garcia

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

In the Central Great Plains, the predominant crop rotation is winter wheat (Triticum aestivum L.)-fallow. Producers are looking to add diversity and intensity to their cropping systems by adding summer crops, however, the elimination of summer fallow may increase crop production risk. The objective of this study was to use crop simulation modeling to compare the productivity of two fixed rotations [winter wheat-corn (Zea mays L.)-fallow and winter wheat-corn-spring triticale (X Triticosecale Wittmack)] with simulated flexible fallow rotations. The flexible fallow rotations made the decision to plant triticale or use summer fallow prior to winter wheat seeding based …

Using A Micro-Integrator To Eliminate The Numerical Butterfly Effect In Non-Linear Chaotic Partial Differential Equations, Joshua Jemegbe

Electrical Engineering Theses

Chaos theory is a relatively new scientific paradigm for the analysis, simulation and prediction of non-linear phenomena whose initial conditions determine the behavior of their entire time series representation. It finds many applications in mathematics, science, and engineering. These include, but are not limited, to data encryption and decryption, designing secure communication systems, predicting weather patterns, noise fluctuations on data lines, understanding turbulence in fluid flow, and analyzing quantum wells. Systems that exhibit chaos are called chaotic systems. In computing solutions to nonlinear chaotic partial differential equation sets, slight deviations in step size could lead to completely diverging trajectories as …

Compressive Sensing For Speech Signals In Mobile Systems, Sabir Ahmed

Electrical Engineering Theses

Compressive sensing is an emerging and revolutionary technology that strongly relies on the sparsity of the signal. In compressive sensing the signal is sparsely compressively sampled by taking a small number of random projections of the signal, which contain most of the salient information. Compressive sensing has been previously applied in areas like: image processing, radar systems and sonar systems. This research work will discuss the potential implementation of compressive sensing in mobile communication systems and how it will influence their data rates. In a typical mobile communication system, the signal of interest is sampled at least at the Nyquist …

Practical, Scalable Algorithms For Byzantine Agreement, Olumuyiwa Oluwasanmi

Computer Science ETDs

With the growth of the Internet, there has been a push toward designing reliable algorithms that scale effectively in terms of latency, bandwidth and other computational resources. Scalability has been a serious problem especially with peer-to-peer (p2p) networks which may have sizes of more than a million nodes. An important problem in designing reliable algorithms is Byzantine agreement. For reasons of scalability, message complexity is a critical resource for this problem. Unfortunately, previous solutions to Byzantine agreement require each processor to send $O(n)$ messages, where $n$ is the total number of processors in the network. In this dissertation, we show …

Keeping Checkpoint/Restart Viable For Exascale Systems, Kurt Ferreira

Computer Science ETDs

Next-generation exascale systems, those capable of performing a quintillion operations per second, are expected to be delivered in the next 8-10 years. These systems, which will be 1,000 times faster than current systems, will be of unprecedented scale. As these systems continue to grow in size, faults will become increasingly common, even over the course of small calculations. Therefore, issues such as fault tolerance and reliability will limit application scalability. Current techniques to ensure progress across faults like checkpoint/restart, the dominant fault tolerance mechanism for the last 25 years, are increasingly problematic at the scales of future systems due to …

Atlantic Multidecadal Oscillation-Forced Regional Summertime Precipitation Variations In The Central United States, Michael C. Veres

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The purpose of this research is to identify the regional mechanisms by which the Atlantic Multidecadal Oscillation (AMO) influences summer (June-August) precipitation in the central U.S. This was accomplished by running two different sets of simulations using the Weather Research and Forecasting (WRF) regional climate model, one forced by observations and the other forced only by variations in the AMO as obtained via a global climate model (GCM). The results reveal a complex set of mechanisms active in the lower and middle troposphere by which the AMO influences summer circulation and precipitation in the central U.S. During the cold phase …

Cultural Orientation And Drinking Behaviors Among Chinese University Students, Shiyuan Wang

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study aimed to develop a cultural orientation instrument among Chinese university students and to investigate the relationship between cultural orientation and their drinking behaviors. Four research questions were raised regarding these two objectives. A sample of 1421 students from universities in Beijing, Kunming and Wuhan participated in this study. The final instrument included 67 items consisting of 10 factors that loaded on two second-order factors: Chinese and Western culture. Thus, four categories of cultural orientation (Traditional, Western, Bicultural and Marginal) emerged, confirming the applicability of Berry’s acculturation theory in cultural orientation. The result also indicated that traditional oriented group …
