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 …

RESULTS Of the 5 studies analyzed, 3 included a rationale for mixing based on the need …

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 …

Midwest Guardrail System For Standard And Special Applications, Ronald K. Faller, Karla A. Polivka, Beau D. Kuipers, Robert W. Bielenberg, John D. Reid, John R. Rohde, Dean L. Sicking Ph.D.

Department of Civil and Environmental Engineering: Faculty Publications

Development, testing, and evaluation of the Midwest Guardrail System were continued from the original research started in 2000. This new strong-post W-beam guardrail system provides increased safety for impacts with higher-center-of-mass vehicles. 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 …

A Defense Of The Causal Efficacy Of Dispositions, Jennifer Mckitrick

Department of Philosophy: Faculty Publications

Disposition terms, such as 'cowardice,' 'fragility' and 'reactivity,' often appear in explanations. Sometimes we explain why a man ran away by saying that he was cowardly, or we explain why something broke by saying it was fragile. Scientific explanations of certain phenomena feature dispositional properties like instability, reactivity, and conductivity. And these look like causal explanations - they seem to provide information about the causal history of various events.

Philosophers such as Ned Block, Jaegwon Kim, Elizabeth Prior, Robert Pargetter, and Frank Jacksonl have suggested reasons for thinking that dispositions are causally inert. I call this the "Inert Dispositions View." …

Modification Of Growing-Season Surface Temperature Records In The Northern Great Plains Due To Land-Use Transformation: Verification Of Modelling Results And Implication For Global Climate Change, Rezaul Mamood, Kenneth G. Hubbard, Christy Carlson

School of Natural Resources: Faculty Publications

Land-use and land-cover change can modify near-surface atmospheric condition. Mesoscale modelling studies have shown that modification in land use affects near-surface soil moisture storage and energy balance. Such a study in the Great Plains showed that changes in land use from natural grass to irrigated agriculture enhanced soil water storage in the root zone and increased latent energy flux. This increase in latent energy flux would correspond to a decrease in sensible heat flux and, therefore, modify near-surface temperature records. To verify this deduction, we have investigated the changes in the historical near-surface temperature records in Nebraska, USA. We have …

Discrimination Against And Adaptation Of Italians In The Coal Counties Of Oklahoma, David G. Loconto

Great Plains Quarterly (through 2013)

In the late 1800s and early 1900s coal reigned supreme in what is now southeastern Oklahoma. As was the case in the northeastern United States, Italians and other immigrants from southern and eastern Europe were brought in as a form of inexpensive labor to work the mines. Italians had different customs, a different language, a unique appearance, and a lack of training in mining compared with the American, English, Irish, and Scottish miners that preceded them. These differences were the foundation of an atmosphere in which immigrant groups would settle in communities. The results were struggles between southern and eastern …

Book Review: Gone: Photographs Of Abandonment On The High Plains, David Taylor

Great Plains Quarterly (through 2013)

Steve Fitch's photographs depicting the interior of abandoned houses, schools, and stores on the High Plains are struck though with melancholy. Not the self-absorbed and self-pitying brand, but that of an observer who has come upon something tragic - lost potential, displaced lives, failed communities.

Refining Rural Spaces: Women And Vernacular Gentility In The Great Plains, 1880-1920, Andrea G. Radke

Great Plains Quarterly (through 2013)

In 1887 the Plains photographer Solomon Butcher met the David Hilton family in Custer County, Nebraska. Mrs. Hilton desired a photograph to send to relatives back East, but felt embarrassed by the family's sod dwelling. She insisted that Butcher not take a photo of the house, but asked the men to drag the Hiltons' beautiful new pump organ out into the field, where the family could pose around the instrument. The sod house remained outside the photograph, and after the session the men returned the organ to the house. To Mrs. Hilton, the organ became her personal symbol of aspirations …
