Trajectories Of Substance Use Disorders In Youth: Identifying And Predicting Group Memberships, Chih-Yuan Lee, Ken C. Winters, Melanie M. Wall

Department of Family Science and Human Development Scholarship and Creative Works

This study used latent class regression to identify latent trajectory classes based on individuals' diagnostic course of substance use disorders (SUDs) from late adolescence to early adulthood as well as to examine whether several psychosocial risk factors predicted the trajectory class membership. The study sample consisted of 310 individuals originally recruited as children in a long-term prospective study. Diagnoses of alcohol or cannabis use disorders (abuse or dependence) were assessed when individuals were 18 (T1), 20 (T2), and 22 (T3) years old. The results showed that two trajectory classes were identified for both alcohol and cannabis use disorder cases and …

Multi-Element Airfoil Optimization Using Computational Fluid Dynamics, Mustafa Kubilay Ictuzer

Mechanical & Aerospace Engineering Theses & Dissertations

High-lift systems are frequently used on commercial transport aircrafts to obtain low speed performance, in terms of take-off and landing field lengths and approach speed. To maximize the take-off and landing performance within the critical restrictions required by the new generation transport wing designs, enhanced high-lift technologies are needed. Moreover, the economic realities faced by the airlines require a design that is mechanically simple and effective. These facts lead us to the optimization of the high lift systems.

Optimizing a high-lift system improves an aircraft's take-off and landing performance. The weight of the system, the advantages and the disadvantages all …

Body Size And Growth Patterns Of Microtus Pennsylvanicus (Ord.) In Chesapeake, Virginia, Sara E. Bell

Biological Sciences Theses & Dissertations

From Dec 2002-Feb 2008, a capture-mark-release study was conducted on 2 Chesapeake, Virginia populations of meadow voles (Microtus pennsylvanicus). The study sites were effectively 1 ha grids in old fields. Two modified live Fitch-type traps were placed at 12.5 m intervals on grids that were trapped for 3 days each month. In northern North America, voles have distinct breeding cohorts (spring and autumn), experience autumn and winter weight loss, demonstrate both delayed growth and sexual maturation in autumn-born young, have lifespans less than 15 weeks, and average about 35-50 g as adults. Chesapeake voles bred year-round, experienced no …

Interisland Variability Of Dune Plant Community Structure On Virginia's Barrier Islands, Justin K. Shafer

Biological Sciences Theses & Dissertations

The barrier islands of the Virginia Coast Reserve LTER site provide an opportunity to study interisland variability of dune plant communities. My research focused on the variation in biomass and diversity of communities among islands and dune positions. Grassy dunes of young, intermediate and old age were sampled on Smith, Hog, and Parramore Islands. Aboveground biomass was obtained from harvest plots, and roots were extracted from cores. Data were collected on depth to groundwater and total soil nitrogen. Variation in mean aboveground biomass was evident among the islands with the highest values on Hog Island, followed by Smith, then Parramore …

The Role Of Conservation Research And Education Centers In Growing Nature-Based Tourism, Richard Edwards, Eric Thompson

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

There are increasing numbers of private (nonprofit and for-profit) centers that carry out conservation research and education in locations of environmental concern. Such centers generate revenue streams that directly support conservation programs and also sustain surrounding human communities. This paper assesses the size of the centers’ economic impacts. We conducted separate studies of the economic impacts of the Cheetah Conservation Fund (Namibia) and (jointly) the Rowe Bird Sanctuary and Whooping Crane Trust (central Nebraska, USA). We collected data on direct expenditures and surveyed visitors and volunteers on their spending. For the Cheetah Conservation Fund, we estimate total economic impact using …

Proposed Standards And Guidelines For Private Nature Reserves In The Northern Great Plains, Curtis Freese, Dawn Montanye, Steve Forrest

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

More than three-quarters of the land in the Northern Great Plains is privately owned and less than 2% of the region is in public protected areas; therefore, sound private-land management is critical for restoring and conserving the region’s biodiversity. Although considerable progress has been made in recent years in fostering and assembling nature reserves on private lands in various regions of the world, this approach has received little attention in North America, including the Northern Great Plains. We review here recommendations, trends and issues related to private protected areas globally and in Canada and the United States. We then discuss …

Toward A Strategy For The Conservation And Protection Of The World’S Temperate Grasslands, William D. Henwood

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Temperate grasslands are one of the world’s great biomes and were once home to some of the largest assemblages of wildlife the earth has ever known. Today these grasslands are considered the most altered terrestrial ecosystem on the planet and are recognized as the most endangered ecosystem on most continents. While species and habitat declines continue, temperate grasslands have the lowest level of protection of the world’s 14 biomes. With only 4% of the biome under protected status, considerable effort will be required to increase this level of protection. Several international bodies have suggested that achieving at least a 10% …

Cattle Ranching And Biodiversity Conservation As Allies In South America’S Flooded Savannas, Almira Hoogesteijn, Rafael Hoogesteijn

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Cattle ranching in Latin America supports wildlife conservation. Ranching probably represents one of the few land uses in which we can advance conservation goals. The approximately 950,000 km2 of Bolivian, Brazilian, Paraguayan, Colombian, and Venezuelan savannas that are privately owned and dedicated to meat production provide a model for conservation programs. We present a geographic and historical description that covers several centuries and ends with descriptions of seven successful cattle ranches (three in the Venezuelan Llanos and four in the Brazilian Pantanal) where cattle ranching, ecotourism, and wildlife conservation coexist. These three activities support each other: tourism creates additional income …

Book Review: Remarkable Plants Of Texas: Uncommon Accounts Of Our Common Natives By Matt Warnock Turner, Jackie M. Poole

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

At last: a book dealing with numerous Texas plants that is neither a field guide nor a dry litany of ethnobotanical uses. Remarkable Plants of Texas is an easy, informative, and enjoyable read. Its 65 entries cover over 80 species of some of the most common, well-known, and well-used plants of Texas (many of which also occur in the southeastern or southwestern United States or Mexico). The short (four- to eight-page) chapters are grouped by life form: trees, shrubs, and herbaceous plants (also including cacti, grasses, vines, and aquatics). Although most treatments are about a single species, a few cover …

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This volume is a capstone of George W. Gill’s long and productive (and continuing) career at the University of Wyoming, where he has spent the last three and a half decades teaching and in pursuit of the data encapsulated here. Contributions from 21 scholars, most of them his students, present studies of bioarchaeology and skeletal biology, especially in the fields of demography, pathology, and morphology. The 19 chapters (and the introductory comments by William M. Bass, Douglas H. Ubelaker, and the senior editor) cover 10,000 years on the Northwestern Plains, from the Archaic period to historic times, encompassing studies of …

C - Reactive Protein Induced Rearrangement Of Phosphatidylcholine On Nanoparticle Mimics Of Lipoprotein Particles, Marilyn R. Mackiewicz, Heather L. Hodges, Scott M. Reed

Chemistry Faculty Publications and Presentations

Lipid-coated metal nanoparticles are developed here as a mimic of low-density lipoprotein (LDL) particles and used to study C-reactive protein (CRP) binding to highly curved lipid membranes. A 12 nm shift in the localized surface plasmon resonance (LSPR) was observed when CRP was added to the lipid-coated gold nanoparticles. Transmission electron microscopy (TEM) revealed that CRP induced a structural change to the lipids, resulting in clusters of nanoparticles. This clustering provides a visualization of how CRP could cause the aggregation of LDL particles, which is a key step in atherosclerosis. The cluster formation and resultant LSPR shift requires the presence …

The Genetic Heritability
 Of
 Survey
 Response 
Styles, Levente Littvay

Survey Research and Methodology Program: Dissertations, Theses, and Student Research

This study assesses the genetic heritability of various survey response styles using a classical twin design. The National Survey of Midlife Development in the United States (MIDUS) collected in 1995-96 included an oversample of twins with self-reported zygosity along with a large number of survey items that allowed for the assessment of acquiescent and extreme response style. The MIDUS singleton sample was used for the careful development of appropriate and reliable measures of these traits. The second wave of the MIDUS (2005-06), was used to assess the sources of survey response trait stability. Acquiescence appears to have a sizable and …

Narrative Mappings Of The Land As Space And Place In Willa Cather's O Pioneers!, Karen E. Ramirez

Great Plains Quarterly (through 2013)

At the conclusion of Willa Cather's 1913 novel O Pioneers!, Alexandra Bergson muses about landownership, and more broadly about the human-land relationship, by reflecting on the transience of the county plat map, one of the most popular forms of mapping rural America in the late nineteenth and early twentieth centuries. These maps were not only housed at the county clerk's office; by the 1880s and 1890s, while Cather was living in Nebraska, commercialized survey maps periodically were collected and published in large, colorful county atlases, also called plat books, becoming among the most widely circulated maps of rural areas …

Scandal On The Plains: William F. Slocum, Edward S. Parsons, And The Colorado College Controversies, Joe P. Dunn

Great Plains Quarterly (through 2013)

This is a story about a scandal that took place on the western frontier, a sexual harassment crisis involving one of giants of late-nineteenth and early twentieth-century education and the disgraceful treatment of the man who pursued the case. The treatment of the two related incidents in the several official histories of the institution constitutes a travesty that one is tempted to call "scandalous." The physical place of this saga is important because the original events transpired within a burgeoning frontier community and at a young western institution that was successfully carving out its place in the national academic scene. …

Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton

Department of Environmental Studies: Undergraduate Student Theses

Abstract Water temperature and dissolved oxygen (DO) profiles were measured once every month from mid July to mid February in a relatively deep sand-pit lake in southeast Nebraska. These profiles showed depleted DO concentrations below the thermocline during summer stratification indicating areas fish will likely avoid in summer months. Colder temperatures in fall caused complete mixing of the water column allowing fish to inhabit all depths of the lake. An inverse temperature stratification occurred directly below the ice during winter months as ice cover cooled the surface water to below 4 degrees Celsius. Ice cover also blocked air – water …

Herbicides And Amphibian Populations, Zach Shirk

Department of Environmental Studies: Undergraduate Student Theses

Amphibians are a unique class of species that are found worldwide except Antarctica and Greenland. They range in size from a few millimeters to over six feet long. Amphibian’s habitats are as various as their size, but one thing in common is that amphibians require an aquatic location to breed. Amphibians live in deserts, mountain prairies, rain forest, wetlands, and almost everywhere in between. Amphibians are an integrated part of most natural ecosystems across the world. Amphibians are a critical part of many food chains; they provide the important link between secondary and tertiary consumers. Amphibians are indicator species in …

Space Use And Mating Activities In The Speckled Rattlesnake, Xavier Glaudas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our understanding of space use variation in response to the temporally varying importance of specific resources is poorly understood in reptiles, because spatial studies are rarely placed into an explicit ecological and behavioral context. I examined how space use differed between the mating and post-mating seasons, and how this variation related to three important resources, mating partners, food, and refuge, in an adult population of the speckled rattlesnake Crotalus mitchellii in the Mojave Desert of southwestern North America. During the mating season (late April to early June), Crotalus mitchellii increased distance traveled per unit time, because wide-ranging behavior likely enhances …

The Role Of Transcription In Stationary Phase Mutagenesis In Bacillus Subtilis, Holly Anne Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Stationary phase mutagenesis, also known as stress-induced or adaptive mutagenesis, is defined as the accumulation of mutations during conditions of no net growth or conditions of stress. This process has been implicated in acquiring antibiotic resistance and evasion of host immune responses in microbial pathogens and in the generation of mutations that lead to neoplasia in animal cells. Previous work has shown that defects in DNA synthesis and repair systems contribute to the formation of adaptive mutations; however the role of transcription in the accumulation of mutations is still being examined. It is speculated that transcriptional derepression leads to an …

Counter-Mapping As Place-Framing: Naturalized Injustice, De-Naturalized Community And Organizing For Social Change On Google Earth, Joshua P. Ewalt

Department of Communication Studies: Dissertations, Theses, and Student Research

In this thesis, I perform an analysis of counter-mapping on Google Earth as a process of organizing for social change. I address the process of mapping the virtual earth as an act of place-framing, an organizing process by which space is transformed to place so as to motivate action on the part of current and potential organizational adherents. Specifically, I argue that there are at least two ways in which place is framed on Google Earth so as to motivate action: place as “naturalized injustice” and place as “de-naturalized community.” Using the analytical vocabulary of collective action framing, and Martin’s …

Effects Of Aquaculture On Migration And Movement Patterns Of Double-Crested Cormorants, D. Tommy King, Bradley F. Blackwell, Brian S. Dorr

United States Department of Agriculture Wildlife Services: Staff Publications

We analyzed 10,620 recovery records for double-crested cormorants (Phalacrocorax auritus) banded as nestlings from 1923 to 2006 to determine the population’s age structure, migration routes, dispersal patterns, and the possible influence of the expansion of the aquaculture industry in the southeastern United States on these population characteristics. Ninety-nine percent of the birds were banded during June to August, and 78% were banded as pre-fl edged birds. Cormorants banded in the interior region of the United States comprised 91% of all birds banded from 1955 to 2006; these birds wintered primarily in the Lower Mississippi Valley and the northern …

Identity Of Diphyllobothrium Spp. (Cestoda: Diphyllobothriidae) From Sea Lions And People Along The Pacific Coast Of South America, Robert L. Rausch, Ann M. Adams, Leo Margolis

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Host specificity evidently is not expressed by various species of Diphyllobothrium that occur typically in marine mammals, and people become infected occasionally when dietary customs favor ingestion of plerocercoids. This report mainly concerns two species, Diphyllobothrium pacificum and Diphyllobothrium arctocephalinum, for which sea lions (Otariidae) are final hosts. The taxonomic status of those cestodes has not been clearly discernible because of misinterpretation of relationships; complex synonymies have resulted from misidentification(s). Stiles and Hassall in 1899 obtained, but did not describe, cestodes from the northern fur seal (Otariidae; Pribilof Islands). That taxon was subsequently studied by several investigators, with diverse …

Eradicating Rats On Lehua Island, Hawaii, With The Help Of Gis And Gps, Justin W. Fischer, Peter Dunlevy

United States Department of Agriculture Wildlife Services: Staff Publications

Lehua Island is an uninhabited, 290-acre crescent-shaped volcanic cone located approximately 150 miles north-northwest of Honolulu, Hawaii, or approximately 20 miles west of the island of Kauai. Lehua is a state-designated seabird sanctuary managed by the Hawaii Department of Land and Natural Resources (HIDLNR) and federally owned by the U.S. Coast Guard. Renowned for its diversity of nesting seabirds, it is home to at least 17 recorded species of seabirds, including, but not limited to, colonies of Laysan and black-footed albatross, red-footed and brown boobies, black noddies, and Newell's shearwaters. Lehua is also home to several species of native coastal …

Temperamental Attention And Activity, Classroom Emotional Support, And Academic Achievement In Third Grade, Kathleen Moritz Rudasill, Kathleen Cranley Gallagher, Jamie M. White

Department of Educational Psychology: Faculty Publications

The purpose of this study is to examine the interplay of children’s temperamental attention and activity (assessed when children were 4-and-a-half years old) and classroom emotional support as they relate to children’s academic achievement in third grade. Particular focus is placed on the moderating role of classroom emotional support on the relationship between temperament (attention and activity level) and academic achievement. Regression analyses indicated that children’s attention and activity level were associated with children’s third grade reading and mathematics achievement, and classroom emotional support was associated with children’s third grade reading and mathematics achievement. In addition, classroom emotional support moderated …

Executive Function Skills Of 6–8 Year Olds: Brain And Behavioral Evidence And Implications For School Achievement, Victoria J. Molfese, Peter J. Molfese, Dennis L. Molfese, Kathleen Moritz Rudasill, Natalie Armstrong, Gillian Starkey

Department of Educational Psychology: Faculty Publications

Academic and social success in school has been linked to children’s self-regulation. This study investigated the assessment of the executive function (EF) component of self-regulation using a low-cost, easily administered measure to determine whether scores obtained from the behavioral task would agree with those obtained using a laboratory-based neuropsychological measure of EF skills. The sample included 74 children (37 females; M = 86.2 months) who participated in two assessments of working memory and inhibitory control: Knock–Tap (NEPSY: Korkman, Kirk, & Kemp, 1998), and participated in event-related potential (ERP) testing that included the directional stroop test (DST: Davidson, Cruess, Diamond, O’Craven, …

Misconstruals Or More? The Interactions Of Orbit Diagrams And Explanations Of The Seasons, Victor R. Lee

Instructional Technology and Learning Sciences Faculty Publications

This paper examines a “misconstrual hypothesis” regarding diagrams of the Earth’s orbit around the sun and how middle school students explain the cause of the seasons. Drawing from 24 semi-structured interviews, I present qualitative analyses of students’ explanations of why temperatures vary in summer and winter and how those are influenced by the elliptical shape of perspective drawings of the Earth’s orbit, common to many science textbooks. The results of the analysis suggest that diagram interpretation does not necessarily follow what has been often predicted in the literature and that conceptualizations can shift quite rapidly as different diagram features are …

Mechanical Impact Of Incisor Loading On The Primate Midfacial Skeleton And Its Relevance To Human Evolution, Qian Wang, Barth Wright, Amanda L. Smith, Janine Chalk, Craig Byron

Faculty and Staff Publications

The midfacial skeleton in the human lineage demonstrates a wide spectrum of variation that may be the consequence of different environmental and mechanical selective pressures. However, different facial configurations may develop under comparable selective regimes. For example, the Neanderthal high and projected face and the Inuit broad and flat face are hypothesized to be the consequence of (1) life in a cold climate, and (2) excessive paramasticatory stresses focused on the anterior dentition. In this study, the second of these two hypotheses is tested using finite element analyses of a monkey skull. Results indicate that incisor loading induces heavy stress …

The Structural Rigidity Of The Cranium Of Australopithecus Africanus: Implications For Diet, Dietary Adaptations, And The Allometry Of Feeding Biomechanics, David S. Strait, Ian R. Grosse, Paul C. Dechow, Amanda L. Smith, Qian Wang, Gerhard W. Weber, Simon Neubauer, Dennis E. Slice, Janine Chalk, Brian G. Richmond, Peter W. Lucas, Mark A. Spencer, Caitlin Schrein, Barth Wright, Craig Byron, Callum F. Ross

Faculty and Staff Publications

Australopithecus africanus is an early hominin (i.e., human relative) believed to exhibit stress-reducing adaptations in its craniofacial skeleton that may be related to the consumption of resistant food items using its premolar teeth. Finite element analyses simulating molar and premolar biting were used to test the hypothesis that the cranium of A. africanus is structurally more rigid than that of Macaca fascicularis, an Old World monkey that lacks derived australopith facial features. Previously generated finite element models of crania of these species were subjected to isometrically scaled loads, permitting a direct comparison of strain magnitudes. Moreover, strain energy (SE) in …

Impact Of Freshman Transition Interventions On Ninth Grade Academic Achievement, Emily Spake Brown

Doctoral Dissertations and Projects

The purpose of this study was to examine the impact of various freshman transition interventions on student academic achievement. Specifically, this study aimed to measure academic success by focusing upon ninth grade End of Course Test (EOCT) scores. The data were collected using a researcher-developed survey. After securing permission from all superintendents, the survey was electronically mailed to all high school principals within the state of Georgia. Among participating systems, the survey response rate was 78.4 percent. Based upon expert opinion, the twenty individual intervention items were categorized into three domains. The domain data were analyzed using analysis of variance …
