Parturition Of Mule Deer In Southern Utah: Management Implications And Habitat Selection, Eric D. Freeman Mar 2014

Parturition Of Mule Deer In Southern Utah: Management Implications And Habitat Selection, Eric D. Freeman

Theses and Dissertations

Mule deer (Odocoileus hemionus) are an ecologically, economically, and socially important species across much of the western United States. As such, populations and habitat are intensely managed by state game agencies. However, populations have been declining in recent decades and several factors have been implicated (e.g., climate, predation, competition, and habitat availability). Population dynamics of mule deer are driven by a combination of survival of adults and juveniles and reproductive rates. While adult female mule deer typically have consistently high annual survival rates (85% annually), juveniles are more easily affected by stressors (biotic and abiotic conditions) and therefore …

Achilles Tendon Changes In Downhill, Level And Uphill Running, Katy Andrews Neves Mar 2014

Achilles Tendon Changes In Downhill, Level And Uphill Running, Katy Andrews Neves

Theses and Dissertations

In this study, we examined how hill running affects the Achilles tendon, which is a common location for injuries in runners. Twenty females ran for 10 min on three randomly selected grades (-6%, 0%, +6%). Achilles tendon (AT) cross-sectional area (CSA) was imaged using Doppler ultrasound and peak vertical forces were analyzed using high-speed (240 Hz) videography. A metabolic cart and gas analyzer ensured a similar metabolic cost across grades. Data were analyzed using a forward selection regression. Results showed a decrease in AT CSA from pre-run to post-run (p = .0001). Peak vertical forces were different across grades (p …

Security Of Graph Data: Hashing Schemes And Definitions, Muhammad U. Arshad, Ashish Kundu, Elisa Bertino, Krishna Madhavan, Arif Ghafoor Mar 2014

Security Of Graph Data: Hashing Schemes And Definitions, Muhammad U. Arshad, Ashish Kundu, Elisa Bertino, Krishna Madhavan, Arif Ghafoor

Cyber Center Publications

Use of graph-structured data models is on the rise - in graph databases, in representing biological and healthcare data as well as geographical data. In order to secure graph-structured data, and develop cryptographically secure schemes for graph databases, it is essential to formally define and develop suitable collision resistant one-way hashing schemes and show them they are efficient. The widely used Merkle hash technique is not suitable as it is, because graphs may be directed acyclic ones or cyclic ones. In this paper, we are addressing this problem. Our contributions are: (1) define the practical and formal security model of …

Soil Fertility Status And Degradation Of 2, 4, 6-Trinitrotoluene Contaminated Soils, Chelsea Kae Katseanes Mar 2014

Soil Fertility Status And Degradation Of 2, 4, 6-Trinitrotoluene Contaminated Soils, Chelsea Kae Katseanes

Theses and Dissertations

Current models for predicting the environmental fate of munitions constituents (MC) in soils are based mostly on chemical distribution parameters and neglect the larger considerations of other soil parameters. We are working towards a new approach based on the whole soil activity for predicting the long-term residence time and fate of MC in soils with connection to agronomic soil fertility concepts. These relationships are demonstrated by correlating experiments involving full physical and chemical characterization of eight taxonomically distinct soils, with batch reactor studies determining MC degradation potential. Soils were incubated in a slurry for 10 days in a closed reactor …

Deep Rna Sequencing Reveals Hidden Features And Dynamics Of Early Gene Transcription In Paramecium Bursaria Chlorella Virus 1, Guillaume Blanc, Michael Mozar, Irina V. Agarkova, James R. Gurnon, Giane Yanai-Balser, Janet M. Rowe, Yuannan Xia, Jean-Jack Riethoven, David D. Dunigan, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

Paramecium bursaria chlorella virus 1 (PBCV-1) is the prototype of the genus Chlorovirus (family Phycodnaviridae) that infects the unicellular, eukaryotic green alga Chlorella variabilis NC64A. The 331-kb PBCV-1 genome contains 416 major open reading frames. A mRNA-seq approach was used to analyze PBCV-1 transcriptomes at 6 progressive times during the first hour of infection. The alignment of 17 million reads to the PBCV-1 genome allowed the construction of single-base transcriptome maps. Significant transcription was detected for a subset of 50 viral genes as soon as 7 min after infection. By 20 min post infection (p.i.), transcripts were detected for …

Characterizing Phantom Arteries With Multi-Channel Laser Ultrasonics And Photo-Acoustics, Jami L. Johnson, Kasper Van Wijk, Michelle Sabick Mar 2014

Characterizing Phantom Arteries With Multi-Channel Laser Ultrasonics And Photo-Acoustics, Jami L. Johnson, Kasper Van Wijk, Michelle Sabick

Mechanical and Biomedical Engineering Faculty Publications and Presentations

Multi-channel photo-acoustic and laser ultrasonic waves are used to sense the characteristics of proxies for healthy and diseased vessels. The acquisition system is non-contacting and non-invasive with a pulsed laser source and a laser vibrometer detector. As the wave signatures of our targets are typically low in amplitude, we exploit multi-channel acquisition and processing techniques. These are commonly used in seismology to improve the signal-to-noise ratio of data. We identify vessel proxies with a diameter on the order of 1 mm, at a depth of 18 mm. Variations in scattered and photo-acoustic signatures are related to differences in vessel wall …

Aesthetics For Green Roofs And Green Walls, Richard K. Sutton Mar 2014

Aesthetics For Green Roofs And Green Walls, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

Do green roofs and green walls have aesthetic benefits? Most green roof proponents would say so. But what are they and how do they relate to green roof design in terms of species selection, planting arrangement, viewable context, access, maintenance and other factors? Aesthetics according to the Green Roof Design 101 Manual 2nd Ed (GRHC 2006) provides “pleasure- and psycho-physiologically-oriented benefits” but, this narrow understanding suggests that the aesthetic potential of green roofs is limited to what one might experience looking upon any garden. We suggest other ways that need exploring to make aesthetics more relevant and understandable to …

Psychology Faculty Works

Recent studies on the effect of stress on modulation of fear memory in our laboratory have uncovered endogenous opioid and adrenergic based modulation systems, working in concert, that limit the strengthening or weakening of newly acquired fear memory during consolidation under conditions of mild or intense stress, respectively. The present study sought to determine if similar stress-dependent modulation, mediated by endogenous opioid and adrenergic systems, occurs during reconsolidation of newly retrieved fear memory. Rats underwent contextual fear conditioning followed 24 h later by reactivation of fear memory; a retention test was administered the next day. Stress was manipulated by varying …

Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard Mar 2014

Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard

Intermountain Bird Observatory Publications and Presentations

A critical element of diet analysis is species adaptability to alternative prey sources. The breeding-season diet of Northern Goshawks (Accipiter gentilis) includes both mammalian and avian species, varies geographically, and is often dependent upon tree squirrels of the genera Sciurus andTamiasciurus. We studied alternative prey sources of Northern Goshawks in the South Hills of south-central Idaho, an area where tree squirrels are naturally absent and other prey frequently important in the diet of goshawks, such as smaller corvids, are uncommon. We quantified the diet of goshawks using nest cameras and surveyed abundance of prey using line …

Lead Optimization Of Hmba To Develop Potent Hexim1 Inducers, Bo Zhong, Rati Lama, Wannarasmi Ketchart, Monica M. Montano, Bin Su Mar 2014

Lead Optimization Of Hmba To Develop Potent Hexim1 Inducers, Bo Zhong, Rati Lama, Wannarasmi Ketchart, Monica M. Montano, Bin Su

Chemistry Faculty Publications

The potency of a series of Hexamethylene bis-acetamide (HMBA) derivatives inducing Hexamethylene bis-acetamide inducible protein 1 (HEXIM1) was determined in LNCaP prostate cancer cells. Several compounds with unsymmetrical structures showed significantly improved activity. Distinct from HMBA, these analogs have increased hydrophobicity and can improve the short half-life of HMBA, which is one of the factors that have limited the application of HMBA in clinics. The unsymmetrical scaffolds of the new analogs provide the basis for further lead optimization of the compounds using combinatorial chemistry strategy.

Deference Mistakes, Jonathan Masur, Lisa Larrimore Ouellette Mar 2014

Deference Mistakes, Jonathan Masur, Lisa Larrimore Ouellette

Public Law and Legal Theory Working Papers

This Article begins with what should seem a relatively straightforward proposition: it is impossible to fully understand the holding of a case without understanding its “deference regime”—the standard of review or burden of proof that governs the case. If a court holds in the context of a habeas petition that a constitutional right was not “clearly established,” that does not mean that the court would hold that the right does not exist were it writing on a blank slate. If a court refuses to invalidate a granted patent, which is presumed valid and can only be held invalid upon a …

Nasal T Cell Lymphoma: A Rare Entity, Maliha Kazi, Mubasher Ikram, Montasir Junaid

Section of Otolaryngology, Head & Neck Surgery

Nasal type of Natural Killer (NK)/T cell lymphoma manifests in the nasal cavity. Approximately 95% of them are associated with EBV(Ebstein Barr Virus) with a strong predilection for the Asian population. It has certain systemic and localized symptoms which aid in diagnosis of the condition. However, the histological criteria is pivotal in confirming the diagnosis as well as aiding in confirming the association of EBV. Nasal type of NK/T cell lymphoma has a guarded prognosis. Treatment plan include radiotherapy with concurrent chemotherapy. Despite all this, the 5-year survival rate ranges from 15-75%. A 35 years old male presented with an …

Microstructural Abnormalities In Language And Limbic Pathways In Orphanage-Reared Children: A Diffusion Tensor Imaging Study, Ajay Kumar, Michael E. Behen, Piti Singsoonsud, Amy L. Veenstra

University Faculty Publications and Creative Works

This study utilized diffusion tensor imaging fiber tractography to examine the miscrostructural integrity of limbic and paralimbic white matter tracts in 36 children (age M = 124 months) with histories of early deprivation, raised from birth in orphanages and subsequently adopted into the United States, compared to 16 age-matched typically developing children. We found increased mean diffusivity bilaterally in the arcuate fasciculus and increased mean diffusivity and reduced fractional anisotropy bilaterally in the uncinate fasciculus and cingulum in children with early deprivation. Microstructural integrity of the left arcuate fasciculus and right cingulum was related to language and behavioral functioning, respectively. …

Cluster M Mycobacteriophages Bongo, Pegleg, And Rey With Unusually Large Repertoires Of Trna Isotypes, Welkin H. Pope, Kirk R. Anders, Madison Baird, Charles A. Bowman

University Faculty Publications and Creative Works

Genomic analysis of a large set of phages infecting the common host Mycobacterium smegmatis mc2155 shows that they span considerable genetic diversity. There are more than 20 distinct types that lack nucleotide similarity with each other, and there is considerable diversity within most of the groups. Three newly isolated temperate mycobacteriophages, Bongo, PegLeg, and Rey, constitute a new group (cluster M), with the closely related phages Bongo and PegLeg forming subcluster M1 and the more distantly related Rey forming subcluster M2. The clusterMmycobacteriophages have siphoviral morphologies with unusually long tails, are homoimmune, and have larger than average genomes (80.2 to …

Policing By Numbers: Big Data And The Fourth Amendment, Elizabeth E. Joh Mar 2014

Policing By Numbers: Big Data And The Fourth Amendment, Elizabeth E. Joh

Washington Law Review

This article identifies three uses of big data that hint at the future of policing and the questions these tools raise about conventional Fourth Amendment analysis. Two of these examples, predictive policing and mass surveillance systems, have already been adopted by a small number of police departments around the country. A third example—the potential use of DNA databank samples—presents an untapped source of big data analysis. Whether any of these three examples of big data policing attract more widespread adoption by the police is yet unknown, but it likely that the prospect of being able to analyze large amounts of …

Comparing The Effect Of Two Types Of Computer Screen Background Lighting On Students’ Reading Engagement And Achievement, Jennifer A. Botello Mar 2014

Comparing The Effect Of Two Types Of Computer Screen Background Lighting On Students’ Reading Engagement And Achievement, Jennifer A. Botello

Dissertations

With increased dependence on computer-based standardized tests to assess academic achievement, technological literacy has become an essential skill. Yet, because students have unequal access to technology, they may not have equal opportunities to perform well on these computer-based tests. The researcher had observed students taking the STAR Reading test (Renaissance Learning, 2009) and noticed a variance in scores in relation to classroom performance. The researcher intended, therefore, to explore variables that may affect the performance of students on a computer-based reading assessment. The researcher tested two different technology-related variables as students took a summative exam, the STAR Reading test. The …

Traumatic Brain Injury: The Efficacy Of A Half-Day Training For School Psychologists, Susan C. Davies, Ashlyn M. Ray Mar 2014

Traumatic Brain Injury: The Efficacy Of A Half-Day Training For School Psychologists, Susan C. Davies, Ashlyn M. Ray

Counselor Education and Human Services Faculty Publications

The incidence rates of traumatic brain injuries (TBI) are increasing, yet educators continue to be inadequately trained in assessing and serving students with TBIs. This study examined the efficacy of a half-day TBI training program for school psychologists designed to improve their knowledge and skills. Results of quantitative and qualitative survey analysis indicated there was little increase in knowledge and skills from pre-training to one-year follow-up, although participants did increase in confidence related to their decision-making abilities in working with students with TBI. The data indicate a need for future study of more effective training models.

Gender Identity, Ethnic Identity, And Self-Esteem In Latino Adolescent Males, Miriam Asya Reder Mar 2014

Gender Identity, Ethnic Identity, And Self-Esteem In Latino Adolescent Males, Miriam Asya Reder

Master's Theses

The relationship between gender identity and psychological adjustment has long been investigated, but it is only in the 21st century that gender identity has been examined as a multi-faceted construct. According to Egan and Perry (2001), there are five dimensions comprising a person’s gender identity and they have demonstrated a significant relationship between these dimensions and youth’s psychological adjustment. Three of their gender identity constructs are pertinent to this study: gender typicality, gender contentedness, and felt pressure. While subsequent studies have had similar significant results (Carver, Yunger, & Perry, 2003; Yunger, Carver, & Perry, 2004), one study found that …

Nascent Peptides That Induce Translational Arrest, Christopher J. Woolstenhulme Mar 2014

Nascent Peptides That Induce Translational Arrest, Christopher J. Woolstenhulme

Theses and Dissertations

Although the ribosome is a very general catalyst, it cannot synthesize all protein sequences equally well. Certain proteins are capable of stalling the ribosome during their own synthesis. Stalling events are used by both prokaryotic and eukaryotic cells to regulate gene expression. Characterization of natural stalling peptides shows that only a few strategically placed amino acids are needed to inactivate the ribosome. These motifs share little sequence similarity suggesting that there are more stalling motifs yet to be discovered. Here we use two genetic selections in E. coli to discover novel stalling peptides and detail their subsequent characterization. Kinetic studies …

Faculty Senate Newsletter, March 2014, Louisiana State University And Agricultural & Mechanical College

LSU Faculty Senate Publications

Message from President: A temptation for the writer of a “welcome” column to a journal of academic controversy is to win faculty sympathy by selecting the error or abuse of the month and then targeting the perpetrators in some or other corner of the administration. Although it is true that Louisiana higher education suffers from frustrated and stymied as well as from less than altruistic management, it is also true that, up and down the state, faculty members avoid the exercise of assorted options that could make matters better. Given the slow flow of information in secrecy-obsessed Louisiana, it is …
