Cellular Localization And Expression Of Ski Family Proteins In Rhabdomyosarcoma, Brian Lee Reinert May 2010

Cellular Localization And Expression Of Ski Family Proteins In Rhabdomyosarcoma, Brian Lee Reinert

Biomedical Sciences ETDs

Ski and SnoN are two highly related transcription factors that are transcribed from two separate genes named SKI and SKIL, respectively. They are both co-repressors of the Smad-mediated transforming growth factor beta (TGFβ) signaling pathway. Originally they were classified as oncogenes as they have the ability to transform quail fibroblasts. However, they have also been found to have anti-proliferative properties so they are also considered tumor suppressors. They are involved in normal growth and development and thought to be essential as there is evidence that a homozygous mouse knockout of either SKI or SKIL is embryonic lethal. Both Ski and …


Exploiting Query Logs For Cross-Lingual Query Suggestions., Wei Gao, Cheng Niu, Jian-Yun Nie, Ming Zhou, Kam-Fai Wong, Hsiao-Wuen Hon May 2010

Exploiting Query Logs For Cross-Lingual Query Suggestions., Wei Gao, Cheng Niu, Jian-Yun Nie, Ming Zhou, Kam-Fai Wong, Hsiao-Wuen Hon

Research Collection School Of Computing and Information Systems

Query suggestion aims to suggest relevant queries for a given query, which helps users better specify their information needs. Previous work on query suggestion has been limited to the same language. In this article, we extend it to cross-lingual query suggestion (CLQS): for a query in one language, we suggest similar or relevant queries in other languages. This is very important to the scenarios of cross-language information retrieval (CLIR) and other related cross-lingual applications. Instead of relying on existing query translation technologies for CLQS, we present an effective means to map the input query of one language to queries of …

Tracing Deuterium Through The Food Web And Into Birds And Mammals Along An Elevational Gradient In The Southern Rocky Mountains, Matthew J. Baumann May 2010

Tracing Deuterium Through The Food Web And Into Birds And Mammals Along An Elevational Gradient In The Southern Rocky Mountains, Matthew J. Baumann

Biology ETDs

Animals incorporate local δ2H values from available water and dietary sources during tissue synthesis, which can provide evidence of elevational movements if multiple tissues with different turnover times are examined. Here we test the applicability of using δ2H as an indicator of altitudinal movements by examining multiple tissues (δ2Hbw (body water), δ2Hfeather, δ2Hfur, and δ2Hclaw) in birds and mammals in the Sangre de Cristo Mountains. Additionally, we measured δ2Hsw (stem water) and insect δ2bw and δ2wb (whole body) values to assess changes with elevation. We sampled 15 species of birds and two small mammal species along with potential food sources …


Dispersal, Facilitation, And Burrow Architecture In Banner-Tailed Kangaroo Rats, Andrew J. Edelman May 2010

Dispersal, Facilitation, And Burrow Architecture In Banner-Tailed Kangaroo Rats, Andrew J. Edelman

Biology ETDs

The largest and most dominant kangaroo rat species in the Chihuahuan Desert is the banner-tailed kangaroo rat (Dipodomys spectabilis). This keystone species constructs mounds containing a complex burrow system around which their ecosystem engineering activities are centered. I studied a population of banner-tailed kangaroo rats at the Sevilleta National Wildlife Refuge, New Mexico from 2005-2009. Specifically, I examined how banner-tailed kangaroo rats: 1) modify their mounds in response to seasonal conditions; 2) spatially affect harvester ants (Pogonomyrmex rugosus) through ecosystem engineering activities; and 3) differ in timing of natal dispersal between sexes. I used mark-recapture, genetic, experimental, and spatially-explicit methods …


Respiratory Physiology During Gravidity In Crotaphytus Collaris And Gambelia Wislizenii, Casey Anderson Gilman May 2010

Respiratory Physiology During Gravidity In Crotaphytus Collaris And Gambelia Wislizenii, Casey Anderson Gilman

Biology ETDs

During gravidity lizards experience a significant decrease in lung volume as a result of compression by growing eggs within the body cavity. In order to understand the effect of this decrease in lung volume on respiratory physiology of gravid egg-laying lizards I measured changes in: total lung volume, resting and post-exercise expired volume, minute volume, respiratory frequency, and carbon dioxide production during reproduction in Crotaphytus collaris and Gambelia wislizenii. I found that compression of the lungs by eggs resulted in an average 48% (range: 26 to 70%) decrease in total lung volume in C. collaris, and an average 38% (range: …


Why Conical Pots? An Examination Of The Relationship Among Vessel Shape, Subsistence, And Mobility, Claire Kathleen Helton-Croll May 2010

Why Conical Pots? An Examination Of The Relationship Among Vessel Shape, Subsistence, And Mobility, Claire Kathleen Helton-Croll

Anthropology ETDs

This study examines the functional relationship between ceramic cooking vessel shape and subsistence and mobility using vessels from Navajo and Towa-speaking Puebloan groups from the Protohistoric period (A.D. 1450-1700) in the southwestern United States. Conical shape vessels are found in association with mobile foragers throughout the past. Navajo peoples produced Dinetah and Navajo Gray wares, both of which have conical bases. Towa-speaking Puebloan peoples from the Jemez and Pecos areas produced rounded-base cooking vessels. The Navajo and Towa-speaking Puebloans practice different subsistence and mobility strategies. The primary goal of this research was to determine if variation in cooking vessel form …


Childhood Animal Cruelty Methods And Their Link To Adult Interpersonal Violence, Brandy B. Henderson May 2010

Childhood Animal Cruelty Methods And Their Link To Adult Interpersonal Violence, Brandy B. Henderson

Masters Theses and Doctoral Dissertations

Recent research has begun to establish a relationship between childhood acts of animal cruelty and later violence against humans. However, few studies have focused on the influence of animal cruelty methods on later interpersonal violence. In a replication of a study by Hensley and Tallichet (2009) and based on a sample of 180 inmates at medium- and maximum-security prisons in a Southern state, the present study examines the relationship between several retrospectively-identified animal cruelty met hods (drowned, hit, shot, kicked, choked, burned, and had sex with) and interpersonal violence committed against humans. Four out of five inmates reported hitting animals. …

Characterization And Modification Of Helmet Padding System To Improve Shockwave Dissipation, Katelyn Howay May 2010

Characterization And Modification Of Helmet Padding System To Improve Shockwave Dissipation, Katelyn Howay

All Theses

Currently soldiers are being exposed a much higher number of improvised explosive devices (IEDs) and the resulting shockwaves. These shockwaves can cause traumatic brain injuries (TBIs) even without the occurrence of ballistic impact. The focus of this research was to reduce the amount of shockwaves soldiers are exposed to by inserting fibers and woven fabrics into a foam padding system. These fibers and fabrics facilitate the dissipation of the shockwave energy before it is able to penetrate the padding and cause TBIs.
The sound velocity of high-performance fibers, commodity fibers and woven fabric was measured using a Dynamic Modulus Tester. …

Using The Internet To Survey Small Towns And Communities: Limitations And Possibilities In The Early 21st Century, Jolene D. Smyth, Don A. Dillman, Leah Melani Christian, Allison C. O'Neill

Department of Sociology: Faculty Publications

Researchers who are interested in small towns and rural communities in the United States often find that they need to conduct their own sample surveys because many large national surveys, such as the American Community Survey, do not collect enough representative responses to make precise estimates. In collecting their own survey data, researchers face a number of challenges, such as sampling and coverage limitations. This article summarizes those challenges and tests mail and Internet methodologies for collecting data in small towns and rural communities using the U.S. Postal Service’s Delivery Sequence File as a sample frame. Findings indicate that the …

Estimation Of Aboveground Terrestrial Net Primary Productivity And Analysis Of Its Spatial And Temporal Trends In The Conterminous United States From 1997 To 2007 Using Nasa-Casa Model, Sami Khanal

Theses and Dissertations

This study estimated monthly and annual Net Primary Productivity (NPP), an important indicator of carbon sequestration, in the Conterminous US from 1997 to 2007 using Carnegie-Ames-Stanford Approach. Vegetation condition, temperature, precipitation, photosynthetically active radiation and soil water holding capacity were used as model’s inputs. NPP values were lower than mean annual values during the year 2000 to 2003 which was probably due to extreme drought conditions during these years. Higher NPP per square meter was generally found in Savannah and Subtropical eco-divisions whereas Tropical/Subtropical deserts had the lowest NPP. Southeastern states had the highest NPP per square meter thus, made …

Assessing Effects Of Land Use On Streams Along The Natchez Trace Parkway Using Rapid Bioassessment Protocol Techniques, Bonnie Laine Earleywine May 2010

Assessing Effects Of Land Use On Streams Along The Natchez Trace Parkway Using Rapid Bioassessment Protocol Techniques, Bonnie Laine Earleywine

Theses and Dissertations

Stream quality along the Natchez Trace Parkway was evaluated by hydrologic unit code 4 (HUC4) watersheds and habitat assessment scores as a broad and local scale, respectively. Water chemistry parameters and rapid bioassessment techniques for habitat and fish and invertebrate communities were sampled in 18 streams and six HUC4 watersheds. Forest, agriculture, and developed land use had little variation at HUC4 level; land use impacts could not be determined. Turbidity and TSS were important factors determining habitat scores and created a “boundary” separating southern and northern watersheds. A latitudinal trophic shift was observed of fish omnivoreinsectivore- piscivore in southern watersheds …

Samples were processed according to standard microbiological protocols, and microorganisms identified using morphological, biochemical and molecular methods. A total of 71 bacteria (2324 isolates) and 50 fungi (1445 isolates) were …


An Exploration Of Amniotic Fluids As A Possible Source Of Fetal Infection In The Feline Immunodeficiency Virus (Fiv)-Infected Cat Model Of Pediatric Aid, Brittany Tenille Clay May 2010

An Exploration Of Amniotic Fluids As A Possible Source Of Fetal Infection In The Feline Immunodeficiency Virus (Fiv)-Infected Cat Model Of Pediatric Aid, Brittany Tenille Clay

Theses and Dissertations

The role that amniotic fluid (AF) may play in HIV vertical infection is unresolved. We used the FIV-infected cat model to study this question. We hypothesized that AF may be a source of fetal infection if the virus is present in the fluids. However, virus neutralizing (VN) antibodies in AF may limit vertical transfer. Fetuses were delivered from FIV-infected queens by cesarean section at early and late gestation. AFs were aspirated from intact fetal membranes and tested for viral antigen and RNA and for FIV-specific antibody. Randomlyselected samples were tested for VN activity using a syncytium reduction assay. Neither FIV …


Comparison And Analysis Of A Lignite Seam In The Wilcox Group, Choctaw And Kemper County, Mississippi, Joshua M. Johns May 2010

Comparison And Analysis Of A Lignite Seam In The Wilcox Group, Choctaw And Kemper County, Mississippi, Joshua M. Johns

Theses and Dissertations

The Wilcox Group includes the most abundant lignite bearing strata in Mississippi. Currently, the only lignite mine in Mississippi is located in Choctaw County with a proposed mine in Kemper County. Six lignite seams are currently mined in Choctaw County. One of those seams is believed to be continuous, from SE Choctaw County through central Winston County, NE Neshoba County into SW Kemper County (roughly 50 miles). Establishing a cross section from Choctaw to Kemper County verifying a continuous lignite seam would provide a stratigraphic marker horizon in correlation along strike, which is uncommon in the Wilcox Group sediments. Through …

Examining Preferences For Prevention Of Louisiana's Wetland Loss, Ross Gordon Moore

Theses and Dissertations

This study analyzed preferences for wetland-loss prevention in coastal Louisiana. Data were obtained through a contingent-valuation mail survey of a random sample of Louisiana households. Results, based on 511 responses, indicate that respondents have a strong preference for a short-run program (72.41% chose this program over a long-run program or no action). Respondents that had higher incomes, were white, had prior knowledge of ongoing restoration efforts, and had confidence in government were more likely to support some program relative to no action, as were those citing hurricane, environmental, and/or climate-change protection as their primary concern. Older respondents and those with …


Macrophyte Re-Establishment And Deductive Gis Modeling To Identify Planting Locations For Fish Habitat Enhancement Projects, Jonathan Paul Fleming May 2010

Macrophyte Re-Establishment And Deductive Gis Modeling To Identify Planting Locations For Fish Habitat Enhancement Projects, Jonathan Paul Fleming

Theses and Dissertations

Aquatic macrophytes are important components in structuring aquatic communities because they provide physical and biological functions that contribute to the stability of the ecosystem. Macrophytes provide the basis for the aquatic food-web and also provide habitat and refugia for aquatic fauna. In systems that lack macrophytes, anthropogenic re-establishment may be a feasible management approach to improve aquatic ecosystems. Understanding environmental factors that regulate colonization, dispersal, and persistence of aquatic macrophytes is pertinent to re-establishment efforts. The purpose of this study is to test hypotheses regarding success of macrophyte re-establishment efforts in Little Bear Creek Reservoir, Alabama using different macrophyte species, …

Sensory properties of dried kudzu leaves were compared by using three different drying techniques: Convection oven, vacuum and food dehydrator. Covariate analysis determined the effects of leaf size, days, dryers and their interaction on 44 sensory variables. The fitted response regressions were determined …


We Are Clay People: The Struggle Against Choctaw Communal Dissolution, 1801-1861, Gary Coleman Cheek May 2010

We Are Clay People: The Struggle Against Choctaw Communal Dissolution, 1801-1861, Gary Coleman Cheek

Theses and Dissertations

Acculturation has become an integral part of scholarship about Native Americans in the Southeast. Recent studies have focused on trade the eighteenth century and Choctaw entry into the American market economy during the beginning of the nineteenth century. This study analyzes acculturation from 1801 to 1861, carrying the story about cultural change and persistence through the Removal era and to the American Civil War. It argues that while Choctaws acculturated to survive, prosper, and protect autonomy in a changing world, they continuously battled communal dissolution, which threatened to destroy their nation. Some individuals attempted to promote new methods of subsistence, …
