History And Development Of The Eurasian Watermilfoil Program In Iowa, Gary S. Phillips

Journal of the Iowa Academy of Science: JIAS

Following a concerted effort by citizens of the Iowa Great Lakes area to address the threat posed by Eurasian watermilfoil (Myriophyllum spicatum L.) to waterbodies in Iowa, the Iowa Eurasian Watermilfoil Law was passed in 1996 by the Iowa legislature. Passage of this law led to the establishment of the Eurasian Watermilfoil Program in July 1996 to address the requirements specified by this legislation. Since establishment of the Eurasian Watermilfoil Program, numerous activities have been carried out to address the threat posed to aquatic ecosystems by Eurasian watermilfoil. These include public awareness and education, boat access monitoring, aquatic vegetation monitoring, …

Ecological Problems With Iowa's Invasive And Introduced Fishes, Neil P. Bernstein, John R. Olson

Journal of the Iowa Academy of Science: JIAS

Since the time of European settlement, at least 59 non-indigenous fish species have been introduced, reached, or moved within Iowa waters. At least 28 nonnative fish species have been introduced into, or reported from Iowa waters since settlement. Of that number, 10 are established at this time through natural reproduction. In addition, many species of native fishes have been translocated within the state, and we provide documentation for 31 of these species. Two translocated species, gizzard shad (Dorosoma cepedianum) and yellow bass (Marone mississippiensis), have had adverse impacts on Iowa's aquatic ecosystems. While many introductions are thought to be benign, …

Polariton And Free-Exciton-Like Photoluminescence In Zno, D. C. Reynolds, David C. Look, B. Jogai, T. C. Collins

Physics Faculty Publications

An unusual photoluminescence line X has been observed in ZnO at an energy between that of the common donor-bound excitons (DBEs) and the free excitons (FEs). In the presence of a high carrier concentration, induced by a second below-band gap laser, the DBEs decrease in intensity, due to screening, and both the FEs and X increase. Thus, X has free-exciton, rather than bound-exciton, character. However, its electric-field vector lies in the plane perpendicular to the c axis, as is also found for the DBEs. The appearance of X is discussed in terms of the polariton picture.

"What's Good Is Bad, What's Bad Is Good, You'll Find Out When You Reach The Top, You're On The Bottom": Are The Americans With Disabilities Act (And Olmstead V. L. C.) Anything More Than "Idiot Wind?", Michael L. Perlin

University of Michigan Journal of Law Reform

Mental disability law is contaminated by "sanism, " an irrational prejudice similar to such other irrational prejudices as racism and sexism. The passage of the Americans with Disabilities Act (ADA)-a statute that focused specifically on questions of stereotyping and stigma-appeared at first to offer an opportunity to deal frontally with sanist attitudes and, optimally, to restructure the way that citizens with mental disabilities were dealt with by the remainder of society. However, in its first decade, the ADA did not prove to be a panacea for such persons. The Supreme Court's 1999 decision in Olmstead v. L.C. - ruling that …

Invasive Species In Iowa: An Introduction, James J. Dinsmore, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

Concern over the increasing spread of invasive species and the potential impacts of those species on native communities has been the subject of several books and hundreds of research papers in recent years. President Clinton's Executive Order on invasive species in February1999 raised national attention to this issue. Natural resource agencies have been plagued by an ever-increasing number of invasive species and now consider this issue the second most important problem (after habitat loss) in their fight to maintain some semblance of natural communities on this planet. One group of experts estimated that in the United States alone, invasives cost …

War On Weeds: Winning It For Natural Areas, Jerry E. Asher

Journal of the Iowa Academy of Science: JIAS

I am delighted to be here with you today to discuss the rapidly accelerating damage that invasive exotic plants are inflicting on natural areas in this country. This problem may seem overwhelming, but you need not despair because there are economical, realistic, and effective strategies available to meet this challenge.

There are two purposes to this presentation: to give you information you can use to convince others that invasive exotic plants are seriously harmful, and to suggest that we can win this war on invasive exotic plants if we engage enough of the right people.

An Overview And Management Plan Of Iowa's Non-Native, Invasive, Terrestrial Forbs, Deborah Q. Lewis, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

Non-native, invasive forb species have been a problem in Iowa since the earliest decades of Iowa's European settlement. The history of studies of Iowa's invasive plants began with L. H. Pammel, and these studies continue to present. Three tables cite the occurrence of many of these species in the state, with Table 1 listing 93 non-native forbs reported by Pammel, Table 2 citing ten invasive forbs of natural areas, and Table 3 adding 38 observed or potential aggressive species of Iowa's anthropogenic and natural areas.

There has been a divergence of interest and research in the management of invasive species …

More Than A Century Of Change In The Ames, Iowa Flora (1859-2000), William R. Norris, Mark P. Widrlechner, Deborah Q. Lewis, Jimmie D. Thompson, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

We compared two floras compiled in Ames, Iowa: (1) an "historic" flora based on two published floras (1871, 1890) and on 1450 herbarium voucher specimens of plants collected in Ames between 1859 and 1899, and (2) a "current" flora compiled by us during recent fieldwork (1990-2000). Our goals were to determine 1) long-term changes in composition (i.e., the proportion of native species) over time, 2) long-term changes in the abundance of individual plant species over time, and 3) the extent of gains and losses of native and non-native plant species. We found that the proportion of native species declined over …

Purple Loosestrife: History, Management, And Biological Control In Iowa, Amy P. Wiebe, John J. Obrycki

Journal of the Iowa Academy of Science: JIAS

Purple loosestrife (Lythrum salicaria) is an invasive plant species infesting wetlands in North America. Biodiversity and wetland habitat quality are reduced following purple loosestrife establishment. Several management tactics, including cultural, mechanical, and chemical controls, have had limited success in reducing the spread of purple loosestrife. Beginning in the 1990s, a biological control program has introduced several species of natural enemies from Europe that feed on purple loosestrife. Since 1994, Iowa State University has reared and released two species of beetles that feed on purple loosestrife, Galerucella calmariensis and G. pusilla. Biological control is one component of an integrated purple loosestrife …

Forest Invasives In Iowa: Current Problems And Future Issues, John Walkowiak, John Haanstad

Journal of the Iowa Academy of Science: JIAS

Iowa's forest resources of primarily deciduous trees covers over 0.8 million hectares (2 million acres) of upland and floodplain sites too steep or too wet for traditional row crop agriculture. These limited natural forests along with urban trees and shelterbelts plantings of trees are critical for environmental and economic enhancement in the state. Although not yet established in the state, exotic insects, such as gypsy moth, Asian longhorned beetle, and pine shoot beetle, threaten native tree vitality. Established exotic diseases such as oak wilt and Dutch elm disease continue to plague the survival of Iowa's oak and elm resources, respectively. …

Non-Native Amphibians And Reptiles In Iowa, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Only a few species appear as introductions into Iowa in the last 30 years. The bullfrog, Rana catesbeiana, was systematically introduced along with fish stocked from hatcheries in the 1930s and this species continues to spread in northern Iowa where it poses a hazard to smaller frogs. Turtles sold as pets, primarily map turtles (Graptemys pseudogeographica and G. geographica) and red-eared turtles (Trachemys scripta) continue to be found in scattered ponds, usually rural, throughout the state. The eastern box turtle (Terrapene carolma) has been reported in or on the edge of most major Iowa cities even though no breeding population …

Techniques For The Regeneration Of Wideband Speech From Narrowband Speech, Jason A. Fuemmeler, Russell C. Hardie, William R. Gardner

Electrical and Computer Engineering Faculty Publications

This paper addresses the problem of reconstructing wideband speech signals from observed narrowband speech signals. The goal of this work is to improve the perceived quality of speech signals which have been transmitted through narrowband channels or degraded during acquisition. We describe a system, based on linear predictive coding, for estimating wideband speech from narrowband. This system employs both previously identified and novel techniques. Experimental results are provided in order to illustrate the system’s ability to improve speech quality. Both objective and subjective criteria are used to evaluate the quality of the processed speech signals.

The goal of this study was to investigate the subtle interrelationships between the insurance claim’s data and clinic performance of medical institutes. Because the medical claims data increase drastically, the review efforts and processes become rather complex and inefficient. The physicians of review committee should have an enterprise view of the claims.We create the performance indicators from consistent data & meta data established from the clinic performance of medical institutes. We adopted 16 outpatient review indicators. We collected rehabilitation claims in middle branch of NHIB since July 1996 till Feb 1997. The prediction model created using both the neural network …

Clinical Experience In Asian Type Multiple Sclerosis, Der-Sheng Han, Jau-Jia Lin, Yen-Ho Wang, Chih-Chao Yang

Rehabilitation Practice and Science

Multiple sclerosis is a heterogeneous disease entity, and also the most common disabling neurological disorder of people in middle life in USA. The prevalence of multiple sclerosis in Asia is lower than that in Western countries of similar latitude. Besides, there are some different features, clinically as well as pathologically, between this disease in Asia and in Western countries. We collected 27 cases diagnosed as clinically definite MS at NTUH between 1990-2000, whose clinical presentations are restricted to optic nerves and spinal cord. Their clinical charts were reviewed retrospectively, and the data was collected in a standard coding sheet. The …

Lumbar Disc Herniation Along With Ruptured Abdominal Aortic Aneurysm: A Casereport And Literature Review, Woan-Chwen Wu, Chen-Liang Chou, Ming-Chi Yung, Shing-Su Chen, Tcho-Jen Liu, Rai-Chi Chan

Rehabilitation Practice and Science

Abdominal aortic aneurysm is a condition affecting nearly 4% of the elderly population. It has a potential for producing a wide range of symptoms, including abdominal pain and back pain. It is rare that abdominal aortic aneurysm presents with paraplegia. From literature review there have been very few reports of patients who sustained lumbar disc herniation along with ruptured abdominal aortic aneurysm. We reported a 68-year-old man with a previously undiagnosed abdominal aortic aneurysm presenting with acute paraplegia. This patient had a history of lumbar disc herniation and was receiving pelvic traction. He survived after operation, but some long-term sequelae, …

Acoustic Emission For Periodic Inspection Of Composite Pressure Vessels, Bao Rasebolai Mosinyi

Master's Theses - Daytona Beach

Cost savings can be achieved in a wide range of applications by replacing the current procedure for hydrostatic recertification of high-pressure composite gas cylinders with acoustic emission (AE) nondestructive testing. Advantages of AE recertification over the current hydrostatic method include: (1) no water contamination, since pressurization of the cylinders is done with air as opposed to water; (2) the risk of damage is decreased since the test pressure is reduced from 166% of design pressure to 110% of operating pressure; (3) the ability of acoustic emission to detect and locate flaws increases safety; and (4) the in-situ method will reduce …

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer

Faculty Publications

An outbreak of Fusobacterium necrophorum-induced septicemia occurred in a group of 40 captive wild-caught pronghorns (Antilocapra americana). Primary pododermatitis or necrotic stomatitis progressed to produce fatal septicemia with metastatic lesions in the forestomachs, lung, liver, and cecum in 38 of the animals. Two remaining animals were euthanatized because of chronic pododermatitis. Housing the animals in a pasture previously used by bovids and heavy rains with persistence of ground water pools in the pasture were contributing factors in the pathogenesis of this outbreak.

Value For Diversity: An Investigation Of Diversity Climate, Job Satisfaction, Organizational Commitment, And Intent To Leave, Quionna Caldwell

Masters Theses and Doctoral Dissertations

This research examined the relationships of diversity climate via organizational fairness and organizational inclusion (Mor Barak et al., 1998) and job satisfaction, organizational commitment, and intent to leave. Further, personal value for diversity was investigated as a moderator of those relationships. The participants included 202 African American women affiliated with a national sorority. The mean age and years of experience was 29.62 and 4.33, respectively. Data were collected electronically using an Internet site hosting the survey questions. The present study provides evidence that diversity climate positively affects job satisfaction and affective commitment, and negatively affects intent to leave. In addition, …

Effects Of Land Use On Biotic Integrity In Ridge And Valley Streams In The Chattanooga Metropolitan Area, Tennessee-Georgia, Jeannie Long

Masters Theses and Doctoral Dissertations

Twenty-one sites across seven streams in the Chattanooga metropolitan area, Tennessee-Georgia, were studied from April-August, 1999, as part of the Urban Streams Project. All sites are in the Ridge and Valley ecoregion and are part of the Nickajack Reservoir watershed in the Tennessee River system. Study sites were characterized in terms of water quality, habitat, and fish assemblages. Relationships among these features and land use, at both the riparian and watershed scales, were examined. A total of 40 species representing nine families of fishes were collected by electrofishing. Biotic integrity at all sites was degraded to some extent, with 16 …

Wetland Mitigation Banking In Tennessee: An Assessment Of Three Banks Performance, Matthew David Skilling

Masters Theses and Doctoral Dissertations

Each year, the nation as a whole loses nearly 58,000 acres of wetlands. The national goal of both the EPA and the Army Corps of Engineers is to achieve no net loss of wetlands. Wetlands law allows for mitigation of wetland impacts with the implied assumption that the mitigation will adequately compensate for the wetland loss. Mitigation banks are becoming a popular mitigation option. Mitigation banks, due to their large size and ample mitigation ratios, make a significant contribution to the national goal of no net loss. This study evaluates three mitigation banks currently operating in Tennessee. The evaluation is …
