Livestock Depredations By Black Vultures And Golden Eagles, Michael L. Avery, J. L. Cummings

United States Department of Agriculture Wildlife Services: Staff Publications

Black Vulture: The available evidence suggests that black vultures act as typical predators by seeking and disabling vulnerable animals prior to overwhelming and killing them (Gluesing et al., 1980). These birds take the path of least resistance and eat carrion when it is available. Black vultures are opportunists, however, and when the chance arises, they will attack and eat defenseless live animals. Defenseless does not necessarily mean sick or injured. Healthy newborn livestock are defenseless, especially if the mother is exhausted or otherwise not able to care for and protect the offspring. In assessing the role of black vultures as …

Evaluation Of A Deer-Activated Bioacoustic Frightening Device For Reducing Deer Damage In Cornfields, Jason M. Gildorf, Scott E. Hygnstrom, Kurt C. Vercauteren, Greg M. Clements, Erin E. Blankenship, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Deer (Odocoileus spp.) can cause substantial damage to agricultural crops, resulting in economic losses for producers. We developed a deer-activated bio-acoustic frightening device to reduce white-tailed deer (O. virginianus) damage in agricultural fields. The device consisted of an infrared detection system that activated an audio component which broadcast recorded distress and alarm calls of deer. We tested the device against unprotected controls in cornfields during the silking–tasseling stage of growth in July 2001. The device was not effective in reducing damage: track-count indices (F1,4=0.02, P=0.892), corn yield (F1,9=1.27, P=0.289), and estimated damage levels (F1,10=0.87, P=0.374) did not differ between experimental …

Predacides For Canid Predation Management, K. A. Fagerstone, J. J. Johnston, P. J. Savarie

United States Department of Agriculture Wildlife Services: Staff Publications

Throughout the livestock industry in the western United States, control of canid predators was considered to be of considerable importance to the livestock industry, especially to sheep producers, who sufkred high losses from coyotes and wolves. In the 19th century, the demand for predator control was communicated to Congress and the western state assemblies, with the result that predator control was provided in western states by the Fedcral Bureau of Biological Survey in cooperation with state agencies, and by trappers hired by stockmen. Steel traps and poisons were the principal methods used for predator control during the early years of …

Sympathy And Approbation In Hume And Smith: A Solution To The Other Rational Species Problem, David M. Levy, Sandra J. Peart

Jepson School of Leadership Studies articles, book chapters and other publications

This paper examines a key implication of the different conceptions of sympathy and the approbation associated with sympathy in the writings of David Hume and Adam Smith. For Hume, sympathy is an empathy we feel for those like us and hence we are motivated to obtain the praise or approbation of those with whom we sympathize. In Hume’s construction there is a direct link from sympathy to motivation because sympathy is reflected self-love. By contrast, in Smith’s construction sympathy is an act of imagination which only habit makes motivational. The abstraction by our imagination means we earn the approbation (or …

On The "Bitter Quarrel" Between Economics And Its Enemies, Sandra J. Peart

Jepson School of Leadership Studies articles, book chapters and other publications

Economics has long had its enemies. The question is, why? What, precisely, is it about economics that its critics oppose? William Coleman seeks to tell the story of «anti-economics», «to take its measure» (p. 3), and then finally to defend economics from these attacks. His is a broad, sweeping study that uses a wide lens, panoramically over time, to survey the opposition. The crisis in economics, edited by Edward Fullbrook, provides us instead with a detailed snapshot of a recent sort of anti-economics - the Post-Autistic Economics (PAE) movement that originated among French economics students in 2000. Both serve to …

Survivable Virtual Topology Routing Under Shared Risk Link Groups In Wdm Networks, Ajay Todimala, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Network survivability is one of the most important issues in the design of optical WDM networks. In this work we study the problem of survivable routing of a virtual topology on a physical topology with Shared Risk Link Groups (SRLG). The survivable virtual topology routing problem against single-link failures in the physical topology is proved to be NP-complete in [1]. We prove that survivable virtual topology routing problem against SRLG/node failures is also NP-complete. We present an improved integer linear programming (ILP) formulation (in comparison to [1]) for computing the survivable routing under SRLG/node failures. Using an ILP solver, we …

An Analysis Of Mcmc Sampling Methods For Estimating Weighted Sums In Winnow, Qingping Tao, Stephen Scott

School of Computing: Technical Reports

Chawla et al. introduced a way to use the Markov chain Monte Carlo method to estimate weighted sums in multiplicative weight update algorithms when the number of inputs is exponential. But their algorithm still required extensive simulation of the Markov chain in order to get accurate estimates of the weighted sums. We propose an optimized version of Chawla et al.’s algorithm, which produces exactly the same classifications while often using fewer Markov chain simulations. We also apply three other sampling techniques and empirically compare them with Chawla et al.’sMetropolis sampler to determine how effective each is in drawing good samples …

Rerouting Schemes For Dynamic Traffic Grooming In Optical Wdm Mesh Networks, Wang Yao, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Traffic grooming in optical WDM mesh networks is a two-layer routing problem to effectively pack low-rate connections onto high-rate lightpaths, which, in turn, are established on wavelength links. In this work, we employ the rerouting approach to improve the network throughput under the dynamic traffic model. We propose two rerouting schemes, rerouting at lightpath level (RRAL) and rerouting at connection level (RRAC). A qualitative comparison is made between RRAL and RRAC. We also propose the critical-wavelength-avoiding one-lightpath-limited (CWA-1L) and critical-lightpath-avoiding one-connection-limited (CLA-1C) rerouting heuristics, which are based on the two rerouting schemes respectively. Simulation results show that rerouting reduces the …

Maximizing Resource Sharing In Wdm Mesh Networks With Path-Based Protection And Sparse Oeo Regeneration, Xi Yang, Byrav Ramamurthy, Lu Shen

School of Computing: Conference and Workshop Papers

We propose a resource-sharing scheme that supports three kinds of sharing scenarios in a WDM mesh network with path-based protection and sparse OEO regeneration. Several approaches are used to maximize the sharing of wavelength-links and OEO regenerators.

Survivable Traffic Grooming With Path Protection At The Connection Level In Wdm Mesh Networks, Wang Yao, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Survivable traffic grooming (STG) is a promising approach to provide reliable and resource-efficient multigranularity connection services in wavelength division multiplexing (WDM) optical networks. In this paper, we study the STG problem in WDM mesh optical networks employing path protection at the connection level. Both dedicated protection and shared protection schemes are considered. Given the network resources, the objective of the STG problem is to maximize network throughput. To enable survivability under various kinds of single failures such as fiber cut and duct cut, we consider the general shared risk link group (SRLG) diverse routing constraints. We first resort to the …

Survivable Traffic Grooming With Differentiated End-To-End Availability Guarantees In Wdm Mesh Networks, Wang Yao, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Traffic grooming is critical in WDM optical metropolitan area networks (MANS), where low-rate connections are packed onto high-rate wavelength paths (lightpaths). Various applications in the MAN demand different levels of reliability. Therefore, it is necessary to provision connections with differentiated reliability guarantees in the MAN. In this paper, we first present an analytical model to calculate the availability of connections using different protection schemes in WDM optical MANs with general mesh topologies. Then we propose and simulate two grooming algorithms which can provision availability guaranteed connections based on per-connection requirements.

A Load-Balancing Spare Capacity Reallocation Approach In Service-Rich Sonet Metro Mesh Networks, Lu Shen, Xi Yang, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

The next-generation SONET metro network is evolving into a service-rich infrastructure. At the edge of such a network, multi-service provisioning platforms (MSPPs) provide efficient data mapping enabled by Generic Framing Procedure (GFP) and Virtual Concatenation (VC). The core of the network tends to be a meshed architecture equipped with Multi-Service Switches (MSSs). In the context of these emerging technologies, we propose a load-balancing spare capacity reallocation approach to improve network utilization in the next-generation SONET metro networks. Using our approach, carriers can postpone network upgrades, resulting in increased revenue with reduced capital expenditures (CAPEX). For the first time, we consider …

Using Transcendental Phenomenology To Explore The “Ripple Effect” In A Leadership Mentoring Program, Tammy Moerer-Urdahl, John W. Creswell

Department of Educational Psychology: Faculty Publications

Several approaches exist for organizing and analyzing data in a phenomenological qualitative study. Transcendental phenomenology, based on principles identified by Husserl (1931) and translated into a qualitative method by Moustakas (1994), holds promise as a viable procedure for phenomenological research. However, to best understand the approach to transcendental phenomenology, the procedures need to be illustrated by a qualitative study that employs this approach. This article first discusses the procedures for organizing and analyzing data according to Moustakas (1994). Then it illustrates each step in the data analysis procedure of transcendental phenomenology using a study of reinvestment or the “ripple effect” …

Configuration Of Traffic-Responsive Plan Selection System Parameters And Thresholds: Robust Bayesian Approach, Montasir M. Abbas, Anuj Sharma

Department of Civil and Environmental Engineering: Faculty Publications

Traffic-responsive plan selection (TRPS) is one of the two major closed-loop system modes of operation. The TRPS mode is more beneficial than its competitor (time-of-day mode) because of its ability to accommodate abnormal traffic conditions such as incidents, special events, and holiday traffic. However, no guidelines are available for optimal setup of TRPS systems. Improper configuration of a TRPS system can result in inefficient system performance or unstable operation in which the closed-loop system operates in a perpetual transitioning state. The TRPS mechanism implemented in current traffic signal controllers is described, and a Bayesian-based methodology for selecting an optimal set …

Additional design variations of the new system included stiffened versions using reduced (half and quarter) post spacings as well as a standard guardrail design configured with a concrete curb 152 mm (6 in.) high. All full-scale vehicle crash tests were successfully performed in accordance with the Test Level 3 requirements specified in NCHRP Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features. The research …

Four Arguments Against A Marriage Amendment That Even An Opponent Of Gay Marriage Should Accept, Dale Carpenter

Faculty Journal Articles and Book Chapters

In this article, the author argues against a federal constitutional amendment preventing states from recognizing same-sex marriages. As of now, a nationwide policy debate is underway on the merits of providing full marital recognition to gay couples. That debate is still in its infancy and is proceeding in a variety of ways, with divergent policy choices in the states. It should not be cut short by the extraordinary mechanism of a constitutional amendment that would substantially delay or permanently foreclose what may turn out to be a valuable social reform.

To summarize, the four main points the author makes are: …

Copyright Under Siege: The First Amendment Front, Lackland H. Bloom Jr.

Faculty Journal Articles and Book Chapters

Over the past decade, the law of copyright - traditionally an arcane and obscure specialty - has evolved into an extraordinarily controversial legal arena. To a significant extent, though not exclusively, this has been caused by the emerging clashes between copyright on the one hand and digital technology and the internet on the other. Some see copyright as the aggressor in the copyright wars, guilty of threatening the digital revolution, the internet, information policy, privacy, freedom of speech and the public domain. Much of this assault on copyright is culturally driven by the Internet's champions. Inevitably, this cultural challenge is …

Diatom Biostratigraphy Of The Cenozoic Glaciomarine Pagodroma Group, Northern Prince Charles Mountains, East Antarctica, Jason M. Whitehead, David M. Harwood, Barrie Mckelvey, Andrew Mcminn

Department of Earth and Atmospheric Sciences: Faculty Publications

In the northern Prince Charles Mountains glaciomarine sediments of the Pagodroma Group outcrop on Fisher Massif (Mt Johnston and Fisher Bench Formations) and at the Amery Oasis (Battye Glacier and Bardin Bluffs Formations), at locations 300 and 250 km south of the Amery Ice Shelf edge, respectively. Most of the Pagodroma Group consists of ice-proximal glaciomarine diamict, and a much subordinate (<2%) amount of more ice-distal mudstone. Microfossil biostratigraphy based upon in situ and glacially reworked diatoms constrains the ages of the four formations, and identifies at least six intervals of marine fjordal deposition. Sparse diatoms in Mt Johnston Formation diamicts indicate an Early Oligocene age. However, it is …

Human Performance Reliability: On-Line Assessment Using Fuzzy Logic, William J. Kolarik, Jeffrey C. Woldstad, Susan Lu, Huitian Lu

Department of Industrial and Management Systems Engineering: Faculty Publications

This paper presents an on-line approach to monitoring human performance in terms of conditional reliability when one is performing a task. Unlike traditional human reliability analysis, this approach develops a dynamic model that is able to cope with constantly changing conditions that affect operator performance. A fuzzy knowledge-based assessment approach is developed in order to deal with uncertainty and subjectivity associated with human performance assessment. This technology includes three main parts/functions: (i) on-line performance monitoring; (ii) real-time performance forecasting; and (iii) performance reliability assessment. The technology is demonstrated in real-time and provides timely conditioned reliability information regarding task success/failure. In …

Mutual Fund Tournaments: Evidence From Global And International Funds, Michael R. Melton, Thomas S. Zorn, Richard A. Defusco

Department of Finance: Faculty Publications

For a sample of global and international equity mutual funds, we test the proposition that managers likely to end up as “losers” manipulate fund risk differently from interim winners. In contrast with Brown, Harlow, and Starks (1996) who found robust support for the tournament model, we found no evidence of tournament like behavior for international and global mutual funds. A possible explanation of this behavior is that investors in these funds are primarily seeking diversification and therefore are less sensitive to relative performance.

Hydrologic Variation During The Last 170,000 Years In The Southern Hemisphere Tropics Of South America, Sherilyn C. Fritz, Paul A. Baker, Tim K. Lowenstein, Geoffrey O. Seltzer, Catherine A. Rigsby, Gary S. Dwyer, Pedro M. Tapia, Kimberly K. Arnold, Teh-Lung Ku, Shangde Luo

Department of Earth and Atmospheric Sciences: Faculty Publications

Despite the hypothesized importance of the tropics in the global climate system, few tropical paleoclimatic records extend to periods earlier than the last glacial maximum (LGM), about 20,000 years before present. We present a well-dated 170,000-year time series of hydrologic variation from the southern hemisphere tropics of South America that extends from modern times through most of the penultimate glacial period. Alternating mud and salt units in a core from Salar de Uyuni, Bolivia reflect alternations between wet and dry periods. The most striking feature of the sequence is that the duration of paleolakes increased in the late Quaternary. This …

What I Believe About Educational Leadership: A Reflective Essay, Janet Young

Graduate Research Papers

Education, in my opinion, is one of the most honorable professions a person can experience. Each teacher or principal involved with educating children is someone that makes a difference in the lives of children and influences them as they become adults. It is amazing to think about the profound impact each educator has on others. No other occupation has such a responsibility. I believe that all children can learn, and I have had a passion for making that a reality since my childhood. I know that I can help children reach their potential. Parents must know that we cherish their …

Observations Of The Pulsating White Dwarf G 185-32, Bárbara Garcia Castanheira, Matt A. Wood

Aerospace, Physics, and Space Science Faculty Publications

We observed the pulsating hydrogen atmosphere white dwarf G 185-32 with the Whole Earth Telescope in 1992. We report on a weighted Fourier transform of the data detecting 18 periodicities in its light curve. Using the Hubble Space Telescope Faint Object Spectrograph time resolved spectroscopy, and the wavelength dependence of the relative amplitudes, we identify the spherical harmonic degree (ℓ) for 14 pulsation signals. We also compare the determinations of effective temperature and surface gravity using the excited modes and atmospheric methods, obtaining Teff = 11960 ± 80 K, log g = 8.02 ± 0.04 and M = 0.617 ± …

A Vision For Administering An Elementary School, Karen L. Thorpe

Graduate Research Papers

My philosophy of educational leadership has developed from the experiences I have had over the course of my lifetime. It began with the values taught to me by my parents and has continued to build to the present. My parents provided a caring and secure family life for my four siblings and me. Neither my mother nor my father had the benefit of much formal education. Neither was able to graduate from high school because they had the obligation to contribute income to their families during the depression. Perhaps the hardships they lived through were the basis of the values …

Morphology Predicts Suction Feeding Performance In Centrarchid Fishes, Andrew M. Carroll, Peter C. Wainwright, Stephen H. Huskey, David C. Collar, Ralph G. Turingan

Ocean Engineering and Marine Sciences Faculty Publications

Suction feeding fish differ in their capacity to generate subambient pressure while feeding, and these differences appear to relate to morphological variation. We developed a morphological model of force transmission in the fish head and parameterized it with measurements from individual fish. The model was applied to 45 individuals from five species of centrarchid fishes: Lepomis macrochirus, Lepomis punctatus, Lepomis microlophus, Micropterus salmoides and Pomoxis nigromaculatus. Measurements of epaxial cross-sectional area, epaxial moment arm, buccal area and buccal area moment arm were combined to estimate pressure generation capacity for individual fish. This estimation was correlated with pressure measured in fish …
