Assessing The Classification Accuracy Of Digitized National Aerial Photography Program Imagery: Comparison With Botanical Data, Mark Arthur Alexander

Dissertations and Theses @ UNI

The ability to acquire and use remotely sensed data has revolutionized large-scale ecological studies by reducing dependence on difficult and expensive field survey techniques for acquisition of land use and land cover data. Multispectral satellite imagery, typically from the Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and the SPOT High Resolution Visible (HRV) instruments, has proven particularly valuable in surveying and classifying vegetation cover (Frank & Thorn, 1985). Further studies have concluded that alpine vegetation communities and habitats can be mapped successfully by including the geomorphic parameters of elevation, slope, and incidence when classifying remotely sensed data.

Photodecomposition Of Crystal Violet Dye In Water Solution And Suspensions Of Metal Oxides, Tatiana Yurievna Zakharian

Dissertations and Theses @ UNI

Photodecomposition and photodecolorization of crystal violet dye were studied in water solution, hydrogen peroxide solution and suspensions of metal oxides. Spectroscopic evidence for the formation of methylated pararosanilines and demethylated derivatives of Michler's ketone as the reaction intermediates was obtained for the photodecomposition of crystal violet in water solution. The mechanism of formation of the intermediates was discussed in terms of charges of individual atoms calculated using Spartan software.

Photooxidation of crystal violet was shown to occur faster in hydrogen peroxide solution due to the higher oxidation potential of hydrogen peroxide and hydroxyl radicals. A mechanism similar to photooxidation in …

Trade Liberalization And Environmental Quality: Opposing Viewpoints, Additional Issues, And The Necessity Of Intervention, John R. Ubben

Major Themes in Economics

International trade, while promoting economic growth and development, is one of many suspects contributing to excessive rates of environmental degradation. Free trade compromises environmental quality in favor of welfare improvements and economic prosperity. The difficulty of measuring environmental amenities, trade theory’s inability to address externalities and decisions overtime, and numerous market failures regarding socially optimal prices, serve as red flags requiring intervention. The most successful form of intervention is domestic policies that internalize externalities. Intervention is also necessary to balance the interests of environmentalists and free traders and to ensure that the gains from trade are devoted to environmental protection.

Secret Pain : Understanding And Treating Self-Injurious Behaviors In Women, Eva Schoen

Graduate Research Papers

This paper is an attempt to raise awareness of the presence of self-injury in Western societies. Causes, symptoms, related diagnoses, and treatment of self-injurious behaviors will be discussed. Most importantly, however, this paper is meant to challenge and, ultimately, decrease the stigma surrounding SD and increase empathy and compassion for the self-injuring person.

Due to constraints of this research paper, the author focuses on female self-injurers and excludes information on self-injury in mentally retarded individuals and prisoners.

Swallow Summer. Charles R. Brown. 1998. The University of Nebraska Press, Lincoln, NE. 371 pages. ISBN 0-8032-6145-4.

This book, Swallow Summer, is a popular account of the Browns fifteenth year at Cedar Point Biological Station in Keith County, Nebraska. Brown presents a daily log of the activities that he undertakes for the 1995 field season, describing the work supporting his research program. In the preface, Brown hopes Swallow Summer can explain his fascination with Cliff Swallows and why he enjoys his research. His intent is to describe "the challenges, thrills, and frustrations that come with studying wild animals in the …

Morphology, Ultrastructure, And Function Of Extrafloral Nectaries In Three Species Of Caesalpiniaceae, Lenore T. Durkee, Matthew H. Haber, Lisa Dorn, Ann Remington

Journal of the Iowa Academy of Science: JIAS

Light and electron microscopy reveal that the morphologically well-differentiated petiolar nectaries of Chamaecrista fasciculata, Senna hepecarpa, and S. marilandica have an unusually simple anatomy consisting of an epidermis immediately subtended by a mass of small, loosely-packed parenchyma cells. Vascular strands from the petiolar bundles enter the nectary and terminate as phloem within or near this parenchyma. In mature, secreting nectaries, the cuticle of the epidermis extends between the epidermal cells and into the nectary parenchyma, where it occupies, but does not occlude, much of the free space of this tissue. The cutin is not found below the level …

"Epidemic" Depression In School-Age Youth, Trudy L. Erickson

Graduate Research Papers

With the traditional image of children as happy and care-free, it has been troubling to think of them suffering the effects of major depression and dysthymia. Successful intervention for.depressive youth is complicated by failure to diagnose, limited referral or consuItation, and resolute parental denial.

The purpose of this paper is to inform the reader about depression in today's student population. Depression will be defined and described as it is manifested in youth. Typical symptoms and proposed etiologies will be discussed. Finally, suggested interventions will be addressed, although research concerning interventions for depressed youth, particularly children, has been sparse.
