Effects Of Aversive Conditioning On Behavior Of Nuisance Louisiana Black Bears, Jennifer Leigh, Michael J. Chamberlain

Human–Wildlife Interactions

Complaints associated with nuisance activity by Louisiana black bears (Ursus americanus luteolus) in south Louisiana have steadily increased since 2000, demanding intervention by state and federal agencies. As a federally threatened species, Louisiana black bears that are a nuisance require nonlethal management, referred to as aversive conditioning. We used rubber buckshot and dogs to test the effectiveness of management techniques used by the state of Louisiana to deter nuisance bear activity. We captured 11 bears in residential and industrial areas where nuisance bear activity was reported. We fitted bears with radiotransmitting collars and released them within 2 km …

How People Should Respond When Encountering A Large Carnivore: Opinions Of Wildlife Professionals, Dylan E. Brown, Michael R. Conover

Human–Wildlife Interactions

We conducted telephone surveys of wildlife professionals who work with large carnivores to ask their opinions about how people should respond to avoid being injured when confronted by a black bear (Ursus americana), grizzly bear (Ursus arctos), mountain lion (Puma concolor), or gray wolf (Canis lupus). The respondents agreed that the most appropriate response was to try to increase the distance between a person and the carnivore. In the event of an attack by a black bear, mountain lion, or wolf, most respondents said to fight back. Opinion was divided over the …

Evaluation Of Physical Barriers To Prevent Prairie Dog Colony Expansion, Gary W. Witmer, James Gionfriddo, Michael Pipas

Human–Wildlife Interactions

Expansion of black-tailed prairie dog (Cynomys ludovicianus) colonies on public and private lands can result in damage to property. Physical barriers to prairie dogs can be used to minimize human–wildlife conflicts. We evaluated 17 existing barriers in the Fort Collins and Boulder, Colorado, areas. Most barriers were made of a single row of vinyl material; these barriers sustained high levels of damage, primarily from wind, and were frequently breached by prairie dogs digging underneath them. Barriers that included a vegetation and a vinyl barrier or a double-vinyl barrier were wind damaged and breached less frequently than the singlevinyl …

Mammalian Hazards At Small Airports In Indiana: Impact Of Perimeter Fencing, Travis L. Devault, Jacob E. Kubel, David J. Glista, Olin E. Rhodes Jr.

Human–Wildlife Interactions

Fences are used at many airports and small airfields to exclude wildlife from entering critical areas. However, not all fences exclude hazardous mammals reliably, and effective fences can be too expensive for small airports to purchase and maintain. In this study, we evaluated fencing at 10 small airports in Indiana and documented the presence and relative abundance of wildlife within airport boundaries using remote cameras and spotlight surveys. Only 4 airports were completely fenced, and four were Odocoileusvirginianus) or coyotes (Canis latrans) at nine of the airports with remote cameras and during spotlight surveys. There were …

Relationship Between Raccoon Abundance And Crop Damage, James C. Beasley, Olin E. Rhodes Jr

Human–Wildlife Interactions

Wildlife damage to crops is a widespread concern among agricultural producers and wildlife professionals. In the United States, raccoon (Procyon lotor) damage to field corn (Zea maize) has become a serious concern, as raccoon depredation to corn has increased significantly in recent years. However, little information is available to suggest the underlying factors responsible for recent increases in raccoon depredation on agricultural crops because there is a limited understanding of the ecological factors influencing wildlife damage to crops at local scales. During 2004, we initiated a study to elucidate the ecological factors influencing depredation to field …

Use Of A Population Viability Analysis To Evaluate Human-Induced Impacts And Mitigation For The Endangered Lower Keys Marsh Rabbit, David H. Lafever, Paige M. Schmidt, Neil D. Perry, Craig A. Faulhaber, Roel R. Lopez, Nova J. Silvy, Elizabeth A. Forys

Human–Wildlife Interactions

Rapid development and urbanization of the lower Florida Keys in the last 30 years has fragmented the habitat of the Lower Keys marsh rabbit (Sylvilagus palustris hefneri), hereafter called marsh rabbit, and threatened it with extinction. On the Naval Air Station–Key West (NAS), Boca Chica Key, marsh rabbits exist as a meta-population of discrete habitat patches in a matrix of wetlands and airfield facilities. Airfield safety regulations require NAS to maintain vegetation below a minimum height on runway peripheries (clear zones). We developed a spatially-explicit, stage-structured, stochastic matrix model using the programs RAMAS-Metapop and ArcGIS. Model parameters were …

Population And Spatial Dynamics Of Resident Canada Geese In Southeastern Nebraska, Scott R. Groepper, P. Joseph Gabig, Mark P. Vrtiska, Jason M. Gilsdorf, Scott E. Hygnstrom, Larkin A. Powell

Human–Wildlife Interactions

In response to increasing populations, damage complaints, and a desire to understand population and spatial dynamics, we studied population size, survival rates, home ranges, movements, and site fidelity of female resident Canada geese (Branta canadensis) at 18 study sites within 23 km of Lincoln, Nebraska, during 1991–1994. Based on mean flock size (x̄ = 93) and number of collared geese in flocks (x̄ = 13), the estimated population of resident Canada geese was nearly 4,000. Estimated monthly survival for female Canada geese was 0.94, mean home range was 25 km², and mean maximum distance moved between …

Preparation And Characterization Of (Gesbte)) Semiconductors For Phase-Change Optical Storage, Hessa Ali Humeid Al-Shamisi

Theses

In the last decade, the phase change optical recording based upon chalcogenide glasses has advanced remarkably at full-scale commercial applications in the form of rewritable compact disks (CD-RWs). The principle of phase-change optical recording is based on a thermally induced reversible transformation between amorphous and crystalline phases. The search for recording materials possessing fast crystallization rate and long data retention has been pursued. Research results have revealed that Ge-Sb-Te compounds exhibit fast crystallization, which has been explained in terms of their single-phase structure.

In the present work, electrical properties of Ge-Sb-Te thin films using Impedance Spectroscopy, Current-Voltage, and Capacitance-Voltage techniques …

Evaluation Of Nutrient (Protein) – Organism (Fish) Relationship Using A Saturation Kinetic Model, Zainab Saad Abdul Rahman

Theses

The primary objective of this thesis was to demonstrate that the net nutrient (protein) deposition and weight gain as a function of nutrient (protein) intake fits the Saturation Kinetic Model and utilize the model parameters to describe and predict intake-deposition relationship.

Groups of Nile tilapia, Oreochromis niloticus, fry (0.01 g) and small fingerlings (0.15 g) were each separately fed twelve semi purified diets in triplicates to the fingerling and duplicate to the fry trial. Each test diet contains a percentage of protein. Protein levels were 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and 54 percent …

Methyl Bromide Alternatives For Post-Harvest Disinfestation Of Dates, Shamsa Hareb Al-Dhahery

Theses

Methyl bromide is a highly effective fumigant to control infestation of dates by insects such as saw-toothed grain beetle, Oryzaephilus surinamensis. The use of methyl bromide will be phased out by 2015 due its adverse effects on Ozone layer. Therefore, environmentally friendly and cost-effective alternatives for controlling insects in dates during storage are needed. Such a treatment should not degrade quality of dates.

The objective of this study was to investigate the effectiveness of conventional heating, freezing, and microwave heating as alternatives to methyl bromide fumigation and to determine the effect of these treatments on date’s quality. Date samples …

Effect Of Oilfield Brine On Groundwater Quality In Marmul Area, Sultanate Of Oman, Salim Ahmed Sakroon

Theses

During a period of 28 years, more than 96 million m³ of oilfield produced water was re-injected in the shallow aquifer at Marmul oilfield area, and changed groundwater characteristics. The 10 wells of Shallow Water Disposal (SWD) have been used to inject water in shallow groundwater aquifers of Dammam and Rus formations. The disposal of oilfield produced water to shallow aquifer has been continuing since 1980, with approximately 96 Mm³ of produced water having been disposed and an estimation of approximately 9600 m³ oil has been disposed of in this case until the beginning of 2008.

Sttructure-Function Correlations Of The Antagonist Effects Of Flavonoids Present In Medicinal Plants On Oxidative Reactive Molecules, Deema Khalil Al Jayousi

Theses

Flavonoids are phenolic compounds with significant antioxidant properties. The propensity of a flavonoid to inhibit free-radical mediated events is governed by its chemical structure. Since these compounds are based on the flavan nucleus, the number, positions, and types of substitutions influence radical scavenging and chelating activity. The main objective of this thesis was to establish structure-activity relationships of flavonoids by means of experimental and computational techniques.

Initially, a series of dietary flavonoids belonging to the most representative families (flavonols; myricetin, quercetin, morin, kaempferol, and 3-hydrxoyflavone, flavones; flavone and flavanones; naringenin) were studied during the reaction with DPPH radical following addition …

Removal Of Selected Heavy Metals From Wash Water Generated From Ready-Mix Concrete Trucks, Dubai, Uae., Imad Juma Mohammed Abunqira

Theses

Dubai is one of seven Emirates that form the United Arab Emirates. The Emirate of Dubai is currently undergoing a fast-paced construction boom that involves huge amounts of concrete mixes. Such mixes are usually delivered to the site in ready form. The major environmental issue with ready-mix concrete production around the world is water pollution. The wash water generated from ready-mix concrete trucks is extremely alkaline and contains significant levels of heavy metals. Removal of heavy metals from the wash water is an environmental problem and economic concern. This demonstrates the urgent need for safe, feasible and economical methods for …

An Action For A Classical String, The Equation Of Motion And Group Invariant Classical Solutions, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

A string action which is essentially a Willmore functional is presented and studied. This action determines the physics of a surface in Euclidean three space which can be used to model classical string configurations. By varying this action an equation of motion for the mean curvature of the surface is obtained which is shown to govern certain classical string configurations. Several classes of classical solutions for this equation are discussed from the symmetry group point of view and an application is presented.

Quantum Phases For A Generalized Harmonic Oscillator, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

An effective Hamiltonian for the generalized harmonic oscillator is determined by using squeezed state wavefunctions. The equations of motion over an extended phase space are determined and then solved perturbatively for a specific choice of the oscillator parameters. These results are used to calculate the dynamic and geometric phases for the generalized oscillator with this choice of parameters.

The Well-Being Of Nations: Linking Together Trust, Cooperation, And Democracy, William Tov, Ed Diener

Research Collection School of Social Sciences

The theme of this chapter is that cooperative and trusting social relationships tend to enhance people’s subjective well-being (happiness and life satisfaction), and that in turn positive feelings of well-being tend to augment cooperation and trust. Extensive empirical work now supports the fact that sociability, interpersonal warmth, community involvement, and interpersonal trust are heightened by positive emotions. New analyses based on the World Value Survey show that nations that are high on subjective well-being (SWB) also tend to be high on generalized trust, volunteerism, and democratic attitudes. Additional analyses indicate that the association of SWB to volunteerism and democratic attitudes …

The Stress-Affiliation Paradigm Revisited: Do People Prefer The Kindness Of Strangers Or Their Attractiveness?, Norman P. Li, Rose A. Halterman, Margaret J. Cason, George P. Knight, Jon K. Maner

Research Collection School of Social Sciences

Two studies employed a classic affiliation-under-stress paradigm and examined people's preferences for affiliating with kind versus attractive same- and opposite-sex targets. When men were under default conditions of low stress, they preferred to affiliate with attractive women. However, men placed in a high stress situation instead preferred to interact with kind women. Regardless of stress level, women preferred to affiliate with kind, rather than attractive, men. When choosing among interaction partners of their own sex, participants uniformly chose to interact with kind others, regardless of stress level. This research builds on traditional stress-affiliation research, which has focused on whether people …

Anarcho-Multiculturalism: The Pure Theory Of Liberalism, Chandran Kukathas

Research Collection School of Social Sciences

Most modern states today are, at least to some degree, culturally diverse.Trade, tourism, international dialogue among scholars, scientists, and artists,and the movement of skilled labor—as well as migration—have ensured thatfew countries do not contain within them significant numbers of people fromalien cultures. The one cultural minority found almost everywhere is the international frequent flyer. Many societies today are multicultural because theyare open to a diversity of peoples who come and go and, sometimes, stay.
