Channel Rehabilitation To Increase Aquatic Habitat And Reestablish Floodplain Connectivity On The Upper Gila River, Eric Scherff

Water Resources Professional Project Reports

Stream restoration is an opportunity to recover a substantial amount of lost ecosystem structure and function. This may be particularly beneficial for perennial streams in semi-arid regions because of the striking differences in productivity and biodiversity between the riparian corridor and surrounding uplands. We develop a plan to restore floodplain connectivity along a channelized reach of the unregulated Upper Gila River in southwestern New Mexico, and evaluate its potential to provide additional aquatic habitat. To identify the extent of historical channelization, primary and secondary documents are examined. Signs of current geomorphic processes are also considered to formulate a restoration design. …

The Optimal Calibration Hypothesis: How Life History Modulates The Brain's Social Pain Network, David S. Chester, Richard S. Pond Jr., Stephanie B. Richman, C. Nathan Dewall

Psychology Faculty Publications

A growing body of work demonstrates that the brain responds similarly to physical and social injury. Both experiences are associated with activity in the dorsal anterior cingulate cortex (dACC) and anterior insula. This dual functionality of the dACC and anterior insula underscores the evolutionary importance of maintaining interpersonal bonds. Despite the weight that evolution has placed on social injury, the pain response to social rejection varies substantially across individuals. For example, work from our lab demonstrated that the brain's social pain response is moderated by attachment style: anxious-attachment was associated with greater intensity and avoidant-attachment was associated with less intensity …

Hippocampal Ca1 Transcriptional Profile Of Sleep Deprivation: Relation To Aging And Stress, Nada M. Porter, Julia H. Bohannon, Meredith Curran-Rauhut, Heather M. Buechel, Amy L.S. Dowling, Lawrence D. Brewer, Jelena Popovic, Veronique Thibault, Susan D. Kraner, Kuey-Chu Chen, Eric M. Blalock

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: Many aging changes seem similar to those elicited by sleep-deprivation and psychosocial stress. Further, sleep architecture changes with age suggest an age-related loss of sleep. Here, we hypothesized that sleep deprivation in young subjects would elicit both stress and aging-like transcriptional responses.

METHODOLOGY/PRINCIPAL FINDINGS: F344 rats were divided into control and sleep deprivation groups. Body weight, adrenal weight, corticosterone level and hippocampal CA1 transcriptional profiles were measured. A second group of animals was exposed to novel environment stress (NES), and their hippocampal transcriptional profiles measured. A third cohort exposed to control or SD was used to validate transcriptional results …

Dynamically Reconfigurable Management Of Energy, Performance, And Accuracy Applied To Digital Signal, Image, And Video Processing Applications, Daniel Rolando Llamocca Obregon

Electrical and Computer Engineering ETDs

There is strong interest in the development of dynamically reconfigurable systems that can meet real-time constraints in energy/power-performance-accuracy (EPA/PPA). In this dissertation, I introduce a framework for implementing dynamically reconfigurable digital signal, image, and video processing systems. The basic idea is to first generate a collection of Pareto-optimal realizations in the EPA/PPA space. Dynamic EPA/PPA management is then achieved by selecting the Pareto-optimal implementations that can meet the real-time constraints. The systems are then demonstrated using Dynamic Partial Reconfiguration (DPR) and dynamic frequency control on FPGAs. The framework is demonstrated on: i) a dynamic pixel processor, ii) a dynamically reconfigurable …

Adolescent Perceptions And Beliefs Of Proactive-Reactive Aggression Explored Through The Social Information Processing Model Of Aggression., John Salaz

Individual, Family, and Community Education ETDs

Human aggression is a frequently studied aspect of human behavior. Although great strides have been made not one single theory can fully explain the complexity of aggression. The Social Information Processing model of aggression (Crick and Dodge, 1994) has served as a useful tool to examine differences amongst individuals. This model considers mechanisms through which every individual processes social information, ultimately leading towards behavior. This study examined adolescent aggression through the Social Information Processing model. Participants consisted of 149 male and female students from a large urban school district in southwestern United States. Each participant was assessed with measures of …

Incident Shock Mach Number Effects On Richtmyer-Meshkov Mixing With Simultaneous Density And Velocity Measurements, Gregory Orlicz

Mechanical Engineering ETDs

Experiments were performed at the horizontal shock tube facility at Los Alamos National Laboratory to study the effect of incident shock Mach number (M) on the development of the Richtmyer-Meshkov instability after a shock wave impulsively accelerates a varicose-perturbed, heavy-gas curtain (air-SF6-air). Three cases of incident shock strength were experimentally investigated: M = 1.21, 1.36, and 1.50. The resulting instability and subsequent fluid mixing is measured using simultaneous quantitative Planar Laser-Induced Fluorescence (PLIF) and Particle Image Velocimetry (PIV) for the first time in a Richtmyer-Meshkov Mach number study, while exceptional experimental repeatability allows for isolation of Mach number effects. Investigated …

Dileme Slovenske Javnofinančne Konsolidacije Ob Ekonomski Recesiji In Krizi Evroobmočja, Marjan Senjur

Economic and Business Review

In 2009, Slovenia recorded a public budget deficit of two billion euros due to the economic recession. This situation has extended to 2010, which is fiscally unsustainable, so fiscal consolidation is urgently needed. The economic recession has highlighted the macroeconomic instability of the Eurozone, leaving Slovenia with the task of stabilising its economy in an otherwise unstable region of the Eurozone. The situation in the Eurozone has also brought to the fore the issue of the competitiveness of Slovenian exports and Slovenia as a business location. Slovenia needs to create greater competitiveness in the Eurozone, where countries compete in competitiveness, …

Design And Polarimetric Calibration Of Dual-Polarized Phased Array Feeds For Radio Astronomy, Taylor D. Webb

Theses and Dissertations

Research institutions around the globe are developing phased array feed (PAF) systems for wide-field L-band radio astronomical observations. PAFs offer faster survey speeds and larger fields of view than standard single-pixel feeds, which enable rapid sky surveys and significantly increased scientific capability. Because deep space astronomical signals are inherently weak, PAF systems must meet stringent noise and sensitivity requirements. Meeting these requirements requires detailed modeling of the phased array itself as well as the reflector it is mounted on. This thesis details a novel approach to dual-pol PAF design that models the array and reflector as a complete system in …

A Maple Program For Computing Landau-Ginzburg A- And B-Models And An Exploration Of Mirror Symmetry, Evan D. Merrell

Theses and Dissertations

Mirror symmetry has been a significant area of research for geometry and physics for over two decades. Berglund and Hubsch proposed that for a certain family of singularities W, the so called "transposed" singularity WT should be the mirror partner of W. cite{BH} The techniques for constructing the orbifold LG models to test this conjecture were developed by FJR in cite{FJR} with a cohomological field theory generalized from the study of r-spin curves. The duality of LG A- and B-models became more elaborate when Krawitz cite{Krawitz} generalized the Intriligator-Vafa orbifold B-model to include contributions from more than one sector.This thesis …

Liquid Dielectric Spectroscopy And Protein Simulation, Brett Lee Mellor

Theses and Dissertations

Protein electrical properties have been studied using dielectric relaxation measurements throughout the past century. These measurements have advanced both the theory and practice of liquid dielectric spectroscopy and have contributed to understanding of protein structure and function. In this dissertation, the relationship between permittivity measurements and underlying molecular mechanisms is explored. Also presented is a method to take molecular structures from the Protein Data Bank and subsequently estimate the charge distribution and dielectric relaxation properties of the proteins in solution. This process enables screening of target compounds for analysis by dielectric spectroscopy as well as better interpretation of protein relaxation …

Does Social Role Functioning Predict Work Productivity? Further Validation Of The Social Role Scale Of The Outcome Questionnaire, Aaron M. Allred

Theses and Dissertations

Mental health problems are associated with significant losses in work productivity and, consequently, have significant ramifications for business entities and the general economy. Several instruments have been developed to measure productivity-related constructs such as absenteeism and presenteeism. The current study examines the utility of the Outcome Questionnaire-45 (OQ), a commonly used mental health questionnaire, in predicting work productivity. This relationship is explored as a preliminary step in assessing the degree to which changes in mental health brought about by psychotherapy will improve work productivity. Forty-nine participants were recruited from a call center in a small market research firm based in …

Parental Asset Accumulation Trajectories And Children's College Outcomes, Vernon Loke

Center for Social Development Research

The effects of parental assets on children’s educational outcomes have mainly been explored from the perspective of asset holdings. However, the process of asset accumulation may also have effects. While asset-based policies are predicated on the premise of asset accumulation, little is known about the effects of different asset accumulation trajectories. This study attempts to fill this gap. The results indicate that youths born into households that had asset holdings significantly higher than zero have better college outcomes compared to youths born into households with lower levels of net worth that did not increase significantly over time. However, when lower-wealth …

Three Dimensional Characterization Of Vocal Fold Fluid Structure Interactions, Joseph R. Nielson

Theses and Dissertations

Voice quality is strongly linked to quality of life; those who suffer from voice disorders are adversely affected in their social, family, and professional relationships. An effort has been made to more fully understand the physics behind how the voice is created, specifically the fluid structure interactions that occur during vocal fold vibration. Many techniques have been developed and implemented to study both the motion of the vocal folds and the airflow that creates the motion. Until recently these techniques have sought to understand a highly three-dimensional phenomenon with 1D or 2D perspectives.This research focuses on the development and implementation …

Temporal Trends In West Antarctic Accumulation Rates: Evidence From Observed And Simulated Records, Landon Kelly Burgener

Theses and Dissertations

Reconstructed snow accumulation rate observations from five new firn cores show a statistically significant negative trend in accumulation rates over the past four decades across the central West Antarctic ice sheet. A negative temporal trend in accumulation is unexpected in light of rising surface temperatures and simulations run by GCMs. Both the magnitude of the mean accumulation rates and the range of interannual variability observed in the new records compares favorably to older records, suggesting that the new accumulation rate records may serve as a regional proxy for recent temporal trends in West Antarctic accumulation rates. The observed negative trend …

Where There Is Design, Elizabeth A. Crowe

Theses and Dissertations

Giving up a certain amount of control can be healthy, productive, and natural. Nature has an important part to play in our lives, and nature is random even as it obeys natural laws. In the same way, creating ceramic objects requires obedience to the laws of nature even as it benefits from freedom from control. Creation requires a certain amount of letting go of control, allowing nature to take its course, and recognizing when good things happen. I have learned that my most successful pieces emerge when I combine conscious control with serendipity. The work in this show reflects that …
