Ten Suggestions To Strengthen The Science Of Ecology, Gary E. Belovsky, Daniel B. Botkin, Todd A. Crowl, Kenneth W. Cummins, Jerry F. Franklin, Malcolm L. Hunter, Anthony Joern, David B. Lindenmayer, James A. Macmahon, Chris R. Margules, J. Michael Scott

Papers in Ecology

There are few well-documented, general ecological principles that can be applied to pressing environmental issues. When they discuss them at all, ecologists often disagree about the relative importance of different aspects of the science’s original and still important issues. It may be that the sum of ecological science is not open to universal statements because of the wide range of organizational, spatial, and temporal phenomena, as well as the sheer number of possible interactions.We believe, however, that the search for general principles has been inadequate to establish the extent to which generalities are possible.We suggest that ecologists may need to …

Graduate Education In Surgery In The Kingdom Of Saudi Arabia. The Challenge Of Growing Pains., Ahmed A. Alsaddique

Saudi Medical Journal

With the establishment of undergraduate medical education and the progress of health care in the country heralded by the return of well trained and dedicated physicians and surgeons, it was only natural that the attention will be focused on establishing graduate training for the different medical specialties in the Kingdom of Saudi Arabia. This paper addresses the current status of general surgery training in the country and compares our model with the experience of others from the perspective of a program director. It is not the exception, but it is the rule to have challenges at this stage of development. …

Vitamin D Receptor, Her-2 Polymorphisms And Risk Of Prostate Cancer In Men With Benign Prostate Hyperplasia, Mohammed T. Tayeb, Caroline Clark, Neva E. Haites, Linda Sharp, Graeme I. Murray, Howard L. Mcleod

Saudi Medical Journal

OBJECTIVE: Prostate cancer (PRCa) is one of the most common causes of cancer death in men and determinants of PRCa risk remain largely unidentified. Benign prostatic hyperplasia (BPH) is found in the majority of ageing men and has been associated with PRCa. Many candidate genes have been suggested to be involved in PRCa, such as those that are central to cellular growth and differentiation in the prostate gland. The vitamin D receptor (VDR) and HER-2 protooncogene have been shown to be involved in the regulation of cell proliferation and differentiation in prostate cells. Genetic variations of these genes could be …

Fum3p, A 2-Ketoglutarate-Dependent Dioxygenase Required For C-5 Hydroxylation Of Fumonisins In Fusarium Verticillioides, Yousong Ding, Ravi S. Bojja, Liangcheng Du

Liangcheng Du Publications

Fumonisins are polyketide-derived mycotoxins produced by several agriculturally important Fusarium species. The B series fumonisins, FB₁, FB₂, FB₃, and FB₄, are fumonisins produced by wild-type Fusarium verticillioides strains, differing in the number and location of hydroxyl groups attached to the carbon backbone. We characterized the protein encoded by FUM3, a gene in the fumonisin biosynthetic gene cluster. The 33-kDa FUM3 protein (Fum3p) was heterologously expressed and purified from Saccharomyces cerevisiae. Yeast cells expressing the Fum3p converted FB₃ to FB₁, indicating that Fum3p catalyzes the C-5 hydroxylation of fumonisins. …

Management Of Vegetation To Reduce Wildlife Hazards At Airports, Brian E. Washburn, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Wildlife strikes cost civil and military aviation at least S490 million annually in the United States (Cleary et al. [I]). Over 46,500 wildlife strikes with civil aircraft were reported to the U.S. Federal Aviation Administration (FAA) during 1990-2002 (Cleary et al. 111). Aircraft collisions with birds accounted for 97% of the reported strikes, whereas strikes with mammals and reptiles were 3% and Larus spp.), waterfowl such as Canada geese (Branta canadensis), raptors (hawks and owls), and blackbirds (Ictennae)/starlings (Sturnus vulgaris) are the species presently of …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report three species of the digenean genus Parallopharynx, one previously undescribed, from the Área de Conservación Guanacaste (ACG) in northwestern Costa Rica. Parallopharynx gonzalezi, which was originally described in Basiliscus sp. and Ctenosaura similis from central Costa Rica, inhabits C. quinquecarinata; P. jonesi, originally described in Anolis lionotus (syn. Norops oxylophus) from Nicaragua, inhabits N. oxylophus, N. biporcatus, and Basiliscus basiliscus; and the new species, which inhabits B. basiliscus. Parallopharynx matternae n. sp. differs from all other members of the genus by having a metraterm extending posteriad from the genital …

“Emerging” Parasitic Infections In Arctic Ungulates, Susan J. Kutz, Eric P. Hoberg, John Nagy, Lydden Polley, Brett Elkin

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Important drivers for emergence of infectious disease in wildlife include changes in the environment, shrinking habitats or concentration of wildlife, and movement of people, animals, pathogens, or vectors. In this paper we present three case-studies of emerging parasitic infections and diseases in ungulates in the Canadian north. First we discuss climate warming as an important driver for the emergence of disease associated with Umingmakstrongylus pallikuukensis, a nematode lungworm of muskoxen. Then we examine how Protostrongylus stilesi, the sheep lungworm, emerged (or re-emerged) in muskoxen after re-introduction of this host into its historical range made it sympatric with Dall’s …

Willamette River Basin Temperature Tmdl Model: Model Scenarios, Robert Leslie Annear, Michael Lee Mckillip, Sher Jamal Khan, Chris Berger, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The State of Oregon Department of Environmental Quality (DEQ) is developing a TMDL for temperature in the Willamette River basin shown in Figure 1. The study area included the Willamette River and all major tributaries (except the Tualatin River where a TMDL process was already concluded). A large section of the Columbia River was also modeled to provide adequate boundary representation of tidal flows in the lower Willamette River. The Willamette River below the Oregon City Falls in the Portland metropolitan area has a typical diurnal tidal range of 1 m. The development of a dynamic model of temperature and …

"Accommodations" For The Learning Disabled: A Level Playing Field Or Affirmative Action For Elites?, Craig S. Lerner

Vanderbilt Law Review

A growing number of students in American higher education are being diagnosed as "learning disabled" and then using that diagnosis to secure beneficial "accommodations," such as extra time on exams. These accommodations are often said to be mandated by the Americans with Disabilities Act (ADA). This Article challenges the premise that the ADA necessarily requires educational institutions to provide learning disabled students with any accommodations. The ADA defines "disability" as an impairment that substantially limits a major life activity. Whether one is substantially limited is determined with reference not to one's innate abilities, but to the skills of the average …

Re-Assessment Of Carrying Capacities In The Ashburton River Catchment, Alan L. Payne, A M E Van Vreeswyk, K A. Leighton

Agriculture reports

Potential carrying capacities for land systems in the catchment of the Ashburton River were first estimated in 1983 as a result of a rangeland survey of the area undertaken during 1976, 1977 and 1978. Potential carrying capacity (termed capability capacity in the 1988 report) is a suggested sustainable level of use assuming that all pastures are in good range condition, the entire station is adequately watered for the effective management of livestock and seasonal conditions are average.

The Ashburton Land Conservation District Committee had previously requested a re-assessment of carrying capacities for Ashburton stations following the widespread establishment of buffel …

Low Self-Esteem As It Relates To Anxiety And Depression, Joel B. Makowski

Masters Theses

The purpose of this qualitative study was to explore the relationship between low self-esteem and anxiety and/or depression. Participants were selected based on their subjective experience of having high or low self-esteem. Low self-esteem participants were then selected on the basis of their subjective assessment of attributing anxiety/and or depression to their low self-esteem experience. Two high self-esteem and two low self-esteem participants were interviewed.

High self-esteem participants were found to base their self-worth and respect on an internal locus of evaluation. They did not identify any notable anxiety or depression. Low self-esteem participants were found to base their worth …

Developmental Expression Patterns Of "Eyes Absent" Genes I, Ii, And Iii In Xenopus Laevis, Aaron Bishop Glass

Senior Honors Theses

The original eyes absent gene was first located in Drosophila (fruit fly) and its crucial role in embryological sensorial development has stimulated research which has been conducted on this family of genes in mouse, frog, chick and human. Dr. Martin Offield isolated Eya1, 2 and 3 in Xenopus laevis (African clawed frog) in Rob Grainger's lab at the University of Virginia (Personal communication). The present study was a follow up study using the process of in situ hybridization to record the expression patterns of these genes using embryos at various stages of development. After a staining procedure, embryos were photographed …

An Integration Of Biblical Principles In Counseling: Psychology Filtered Through Scripture, Jennifer Marie Mccarron

Senior Honors Theses

Psychology is sometimes rejected altogether by evangelical Christians on the basis that it is a flawed discipline. Evangelicals are threatened by what they might call spirituality hiding behind the veil of science. But psychology must be viewed properly, as must theology, in order to interpret and apply its claims correctly. The Bible may be considered revealed truth, but it is not the only truth God has revealed to humans. The Bible is God's revelation to man in written form, and is reliable as long as it is interpreted and applied properly. God has also given man truth which is outside …

Predictors Of Perceived Work-Family Balance: Gender Difference Or Gender Similarity?, Jennifer Reid Keene, Jill Quadagno

Sociology Faculty Research

This article uses the 1996 General Social Survey (GSS) and the 1992 National Study of the Changing Workforce (NSCW) to examine two issues: the relationship of work characteristics, family characteristics, and work-family spillover to perceptions of work-family balance; and models of “gender difference” versus “gender similarity.” The GSS analysis supports the gender similarity model. It demonstrates that work demands such as the number of hours worked per week and work spillover into family life are the most salient predictors of feelings of imbalance for both women and men. The NSCW includes subtler measures of family spillover into work as well …

Translocation As A Strategy To Rehabilitate The Queen Conch (Strombus Gigas) Population In The Florida Keys, Gabriel A. Delgado, Claudine T. Bartels, Robert A. Glazer, Nancy J. Brown-Peterson, Kevin J. Mccarthy

Faculty Publications

Queen conch (Strombus gigas) stocks in the Florida Keys once supported commercial and recreational fisheries, but overharvesting has decimated this once abundant snail. Despite a ban on harvesting this species since 1985, the local conch population has not recovered. In addition, previous work has reported that conch located in nearshore Keys waters are incapable of spawning because of poor gonadal condition, although reproduction does occur offshore. Queen conch in other areas undergo ontogenetic migrations from shallow, nearshore sites to offshore habitats, but conch in the Florida Keys are prevented from doing so by Hawk Channel. The present study was initiated …

A New Method For Estimation Of The Sensible Heat Flux Under Unstable Conditions Using Satellite Vector Winds, Jiayi Pan, Xiao-Hai Yan, Young-Heon Jo, Quanan Zheng, W. Timothy Liu

Faculty Publications

It has been difficult to estimate the sensible heat flux at the air - sea interface using satellite data because of the difficulty in remotely observing the sea level air temperature. In this study, a new method is developed for estimating the sensible heat flux using satellite observations under unstable conditions. The basic idea of the method is that the air - sea temperature difference is related to the atmospheric convergence. Employed data include the wind convergence, sea level humidity, and sea surface temperature. These parameters can be derived from the satellite wind vectors, Special Sensor Microwave Imager (SSM/I) precipitable …

Cultural Literacy And The Field Of The Media, Tony Schirato, Jen Webb

Reconstruction: Studies in Contemporary Culture

[First paragraph]

This paper is concerned with the notion of cultural literacy, specifically with regard to the media, and focuses on two interrelated questions. First, what do we mean by the term cultural literacy, and how can this term be extended and applied to the field, texts and practices of the media? Second, what is it about the place and function of the media in the contemporary world that requires us (as citizens, educators or audiences) to be culturally and media literate?

Endangered Species Act Innovations In The Post-Babbittonian Era--Are There Any?, J.B. Ruhl

Vanderbilt Law School Faculty Publications

One of the mysteries of environmental policy in the Bush Administration will be how and why it squandered an opportunity to continue market-based administrative reforms of the Endangered Species Act begun, ironically, in the Clinton Administration under the direction of then Secretary of the Interior Bruce Babbitt. This article traces the momentum built for reform in the Babbittonian era and examines what has not happened since then.

The Battle Over Endangered Species Act Methodology, J.B. Ruhl

Vanderbilt Law School Faculty Publications

The substantive contours of the Endangered Species Act (ESA) have been largely worked out for quite some time. Starting in the mid-1990s, however, opponents of Fish and Wildlife Service and National Marine Fisheries Service decisions realized that the methodological contours of the ESA were not nearly as settled as their substantive kin. Industry and environmental interests alike appreciate that how these methodological rules get worked out could revolutionize the ESA for decades to come, and during the 1990s they opened the debate over ESA methodology and have been going strong at it ever since. This Article explores the breadth and …

George H. Brimhall's Legacy Of Service To Brigham Young University, Joseph H. Groberg, Mary Jane Woodger

BYU Studies

Franklin S. Harris, president of Brigham Young University from 1921 to 1945, said of his predecessor, George H. Brimhall (fig. 1), "George H. Brimhall, under a tree would make a university any day for where he teaches students will always gather to be taught." Brimhall had two great causes, Harris said: his religion and the cause of education. From his youth to his old age, Brimhall carried these causes forward with unrelenting vigor. In his service as president of Brigham Young University (1904-1921), they merged into one: a university supported by, loyal to, and controlled by The Church of Jesus …

Developmental Changes In Pedunculopontine Nucleus (Ppn) Neurons, T. Kobayashi, C. Good, J. Biedermann, Christina B. Cooley, R. D. Skinner, E. E. García-Rill

Chemistry Faculty Research

The developmental decrease in rapid-eye-movement (REM) sleep in man occurs between birth and after puberty. We hypothesize that if this decrease in REM sleep does not occur, lifelong increases in REM sleep drive may ensue. Such disorders are characterized by hypervigilance and sensory-gating deficits, such as are present in postpubertal onset disorders like schizophrenia, panic attacks (a form of anxiety disorder), and depression. The decrease in REM sleep in the rat occurs between 10 and 30 days of age. We studied changes in size and physiological properties of pedunculopontine nucleus (PPN) cells involved in the control of arousal, i.e., waking …
