Dynamics Of Random Boolean Networks Governed By A Generalization Of Rule 22 Of Elementary Cellular Automata., Gary L. Beck Dec 2006

Dynamics Of Random Boolean Networks Governed By A Generalization Of Rule 22 Of Elementary Cellular Automata., Gary L. Beck

Student Work

This study considers a simple Boolean network with N nodes, each node's state at time t being determined by a certain number of k parent nodes. The network is analyzed when the connectivity k is fixed or variable. This is an extension of a model studied by Andrecut [4) who considered the dynamics of two stochastic coupled maps. Making use of the Boolean rule that is a generalization of Rule 22 of elementary cellular automata, a generalization of the formula for providing the probability of finding a node in state 1 at a time t is determined and used to …


Secularism In Turkey: The Perpetual Tipping Point: Key To The Future Or Prelude To Collapse, Peter R. Catalono Dec 2006

Secularism In Turkey: The Perpetual Tipping Point: Key To The Future Or Prelude To Collapse, Peter R. Catalono

Student Work

During the Cold War, the strategic significance of Turkey to the United States was clear: limit the expansion of the Soviet Union and maintain control of the Dardanelles. For the past decade and a half Western policymakers (US and European) have sent mixed signals to the Turks as to the importance of Turkey in the region, as a bridge between East and West, and in the World. Through eight decades of secular rule Turkey has shown that a democratic and secular state can exist within an almost entirely Muslim population. This thesis is made up of five main parts that …


The Political Career Of Robert B. Crosby, Nebraska Governor, 1953-1955, Theodore J. Wehrbein Dec 2006

The Political Career Of Robert B. Crosby, Nebraska Governor, 1953-1955, Theodore J. Wehrbein

Student Work

This thesis examines the political career of Robert B. Crosby, Nebraska's twenty-seventh governor, whose early popularity ended with his efforts to comply with a State Supreme Court mandate to equalize state-wide property tax assessments. Elected to the Nebraska Legislature in 1940 and re-elected in 1942, Crosby was chosen at the age of 31 as the Speaker of the Legislature in 1943, the youngest person ever to hold that position. After serving two years in the United States Navy, he successfully ran as a Republican candidate for Lieutenant Governor in 1946, and then, in a landslide victory, was elected Governor in …


A Spatial Analysis Of The Foreign-Born Population In Douglas Sarpy County, Nebraska – 2000, Leigh Anne L. Opitz Dec 2006

A Spatial Analysis Of The Foreign-Born Population In Douglas Sarpy County, Nebraska – 2000, Leigh Anne L. Opitz

Student Work

For a city that was initially settled mostly by Europeans, the recent immigrants largely from non-European countries, arriving in a changed urban and societal setting, have altered the settlement geography of Omaha, Nebraska. Due to the economic attainment of many newcomers to the country, many immigrant groups are able to settle in more prosperous areas than previous immigrants, and therefore live further away from the inner city. The transportation infrastructure throughout the city has also improved since the beginning of the century, so immigrants are able widen their geographic mobility. The resulting settlement pattern of these new immigrants is therefore …

Taxonomic And Paleoclimatic Significance Of Late Cretaceous Wood From The San Juan Basin, New Mexico., Patrick J. Hudson

Student Work

Fossil wood has been demonstrated to be a powerful tool for studying past environments and biotas. Anatomical structure of silicified woods from Late Cretaceous sediments in northwestern New Mexico was used to conduct a taxonomic survey of plants with secondary growth and tree stature, as well as estimate paleoclimate. A total of 50 specimens compromising both gymnospermous and angiospermous remains were surveyed from deposits within the upper Fruitland and lower Kirtland formations of the San Juan Basin. Anatomical characters were used to designate distinct xylotypes, which were then linked to modern orders or families. Paleoclimate was estimated using three quantitative …

Levels of performance for the Comprehensive School Reform Demonstration programs' students were also found to be congruent with the posttest …


Acceptance Of Technological Change: Do Age, Expertise And Self-Efficacy Matter?, Cheryl Fernandez Aug 2006

Acceptance Of Technological Change: Do Age, Expertise And Self-Efficacy Matter?, Cheryl Fernandez

Student Work

This study was designed to examine the acceptance of change by employees of different ages, in different contexts. This study challenged the stereotypes held against older individuals by proposing that factors other than age contribute to the acceptance of changes. It examined two context-specific variables, self-efficacy and expertise which contribute to acceptance of technological changes. The findings indicated that older individuals with computer experience had higher self-efficacy. On the other hand, younger individuals had higher self-efficacy, regardless of computer experience. Also, individuals who felt younger than they actually were had higher self-efficacy when they had experience with computers, compared to …


Then The Burning Began: Omaha, Riots, And The Growth Of Black Radicalism, 1966-1969, Ashley M. Howard Aug 2006

Then The Burning Began: Omaha, Riots, And The Growth Of Black Radicalism, 1966-1969, Ashley M. Howard

Student Work

Throughout the 1960s, America witnessed one metropolis after another suffer from major civil disturbances. The first of these incidents occurred in Selma, Alabama, but it was not until Watts, California exploded that the nation began to take notice. As America was throttling towards a major race war, nobody anticipated the Midwestern town of 'Omaha, Nebraska to experience the same disturbances larger cities had. Although the life of average Omaha blacks was better than that of many of their urban counterparts, black Omahans still faced frequent job discrimination, lack of adequate educational facilities, and general disenchantment with Northern ghetto life. Between …


The Impact Of E-Government In Bridging The Privilege Gap: A Case Study Of The City Of Omaha, Nebraska, Sandra Denise Andralie Reade Aug 2006

The Impact Of E-Government In Bridging The Privilege Gap: A Case Study Of The City Of Omaha, Nebraska, Sandra Denise Andralie Reade

Student Work

In the United States today, approximately one third of the population fails to access the Internet for one reason or another. This can have dire consequences for local, state, and national governments who are committed to providing e-government services to citizens. These services range from offering information to users to affording citizens the opportunity to place online ballots and almost everything in between. As governments attempt to reach their most unreachable citizens through use of information and communication technologies (ICTs), they are faced with the difficult task of finding ways to overcome factors which can affect citizen access. These factors …


Qualifying The Definition Of Dispositions, Brooke S. Wiseman Dowse Aug 2006

Qualifying The Definition Of Dispositions, Brooke S. Wiseman Dowse

Student Work

The National Council for Accreditation of Teacher Education (NCATE) Standards are in place to ensure teacher preparation programs produce candidates who meet the high standards of the field and who work to help all students learn. NCATE dictates that teacher preparation programs must provide assessment data which demonstrates the knowledge, skills, and professional dispositions of candidates in the program. While teacher preparation programs have historically assessed the areas of knowledge and skills in candidates, the same programs are struggling to understand the concept of dispositions and how to assess the professional dispositions of candidates. The purpose of this research study …


Views Of School Success Among Spanish-. And English-.Speaking Parents, Jessica Gregory-Wells Aug 2006

Views Of School Success Among Spanish-. And English-.Speaking Parents, Jessica Gregory-Wells

Student Work

As the diversity of American society continues to increase, schools are seeing an influx of children from different cultures. One of the fastest growing minority groups is the Latino population. Research shows that Latino children are at risk for underachievement in American schools; however, the reasons for this are still unknown. Many researchers have speculated that factors such as conflicting cultural value systems, differing academic values, and lower levels of acculturation vis-a-vis the dominant culture influence the underachievement of Latino children. In the present study, I investigate the views of both Spanish-speaking and English-speaking parents to determine whether they differ …


Gains In 8th Grade Student's Reading Skills In Group Within A Group And Large Group Guided Reading Instruction, Brian A. Wedemeyer Aug 2006

Gains In 8th Grade Student's Reading Skills In Group Within A Group And Large Group Guided Reading Instruction, Brian A. Wedemeyer

Student Work

The purpose of this study was to compare two guided reading strategies, group within a group instruction and large group guided reading instruction to determine if one is more effective at raising student word meaning, literal comprehension, inferential comprehension and critical judgment achievement test scores. Tri-Center had used both reading strategies. If there is a significant improvement in student achievement levels using one reading strategy over another, it would indicate that Tri-Center Middle School would need to look at converting other reading sections to the more successful reading strategy. The study was limited to 42 students all being eighth grade …

Species richness of native Asteraceae measured along an elevational gradient ranged from a low …


The Influence Of Feedlots On Epiphytic Lichen Species Composition And Cover In Eastern Nebraska., Margaret K. Reed Aug 2006

The Influence Of Feedlots On Epiphytic Lichen Species Composition And Cover In Eastern Nebraska., Margaret K. Reed

Student Work

Environmental factors greatly influence what species of lichens may occur in a particular region. Among these factors is nitrogen deposition in the form of ammonia as a result of feedlot operations, which may be manifested by an increase in bark pH. Epiphytic lichens on trees located in close proximity to medium and large-scale feedlot operations in Eastern Nebraska were analyzed for bark pH levels, species composition and species abundance, then compared to trees located at a greater distance from feedlot operations. Five sites were selected based on the presence of trees and accessibility. Ten trees from each site were selected …


Acquisition And Forensic Analysis Of Volatile Data Stores, Timothy Vidas Jul 2006

Acquisition And Forensic Analysis Of Volatile Data Stores, Timothy Vidas

Student Work

The advent of more witted threats against typical computer systems demonstrates a need for forensic analysis of memory-resident data in addition to the conventional static analysis common today. Some tools are starting to become available to duplicate various types of volatile data stores. Once the data store has been duplicated, current forensic procedures have no vector for extrapolating further information from the duplicate. This thesis is focused on providing the groundwork for performing forensic investigations on the data that is typically stored in a volatile data store, such as system RAM, while creating as small an impact as possible to …

Student Work

This thesis examines key moments in my experience directing Euripides' The Bakkhai (as translated by C. K. Williams) in February of 2003 at the University of Nebraska at Omaha, in partial fulfillment of my Master of Arts degree in Theatre. It also explores some of the theories and techniques which informed that production. Chapter One examines my experience as a theatre practitioner and the factors that led to my directing The Bakkhai. A close reading of selected moments in Euripides' text make up Chapter Two, which also reviews recent literature, defines key terms and explains the choice of translation. Documented …


Restoration Of Quercus Macrocarpa (Bur Oak) Savanna In Iowa's Loess Hills., David A. Mckenzie Jul 2006

Restoration Of Quercus Macrocarpa (Bur Oak) Savanna In Iowa's Loess Hills., David A. Mckenzie

Student Work

Prescribed burning and tree-cutting were used alone and in combination to assess means by which to restore the historic Quercus savanna ecosystem that once dominated the western Iowa Loess Hills. Pre- and post-treatment evaluations of woody and herbaceous understory species, overstory canopy cover, and woody plant density were conducted in permanently established treatment plots approximately 1000-2000m2 in size. Of all plant groups, forb canopy cover increased the most, with the greatest increases occurring in pots that were burned with all trees removed (average increase from 8% to 41%), followed by burned plots with all but Quercus macrocarpa (bur oak) removed …


A Compact Blimp Remote Sensing System For Analysis Of Environmental Change, Joann Sullivan Jun 2006

A Compact Blimp Remote Sensing System For Analysis Of Environmental Change, Joann Sullivan

Student Work

The goal of this research is to demonstrate that developing an inexpensive compact blimp remote sensing system will allow for analysis and change detection of environmental characteristics over a small area. This system has scale and temporal advantages over existing aircraft and space platforms. The blimp remote sensing platform is capable of temporal resolutions of hours or days, while generating low cost, high spatial resolution images. This contrasts with satellite and fixed wing aircraft systems that are costly to purchase and operate, have low temporal resolutions, and may not provide adequate spatial resolution to investigate small scale phenomena. As designed, …


Logic Programming With Solution Preferences: A Declarative Method., Miao Liu May 2006

Logic Programming With Solution Preferences: A Declarative Method., Miao Liu

Student Work

Preference logic programming (PLP) is an extension of constraint logic program­ming for declaratively specifying problems requiring optimization or comparison and selection among alternative solutions to a query. PLP essentially separates the programming of a problem itself from the criteria specification of its solution selection. This thesis presents a declarative method of specifying and executing preference logic programs based on a tabled Prolog system. The method intro­duces a formal predicate mode declaration for designating certain predicates as optimization predicates, and stating the criteria for determining their optimal so­lutions via preference rules. A flexible mode declaration scheme is implemented in a tabled …


Comparative Analysis Of French And U.S Influence In Francophone Africa -A Case Study Of The Republic Of Senegal, Mamadou Faye May 2006

Comparative Analysis Of French And U.S Influence In Francophone Africa -A Case Study Of The Republic Of Senegal, Mamadou Faye

Student Work

This thesis addresses French and U.S. political influence in Francophone Africa, particularly in Senegal-what is known as a French backyard dating back to the Berlin Conference in 1884. This thesis analyzes the political, cultural, and economic influence of the United Sates and France in Francophone Africa, particularly in Senegal in the period following the Cold War (1989 to present). I hypothesize that French political influence has been in decline in its backyard, Francophone Africa, particularly in Senegal and that France seems unable to counteract growing U.S. influence and hegemonic ambitions. The study concludes that while French political decline is not …
