Examining Ambiguities In The Automatic Packet Reporting System, Kenneth W. Finnegan

Master's Theses

The Automatic Packet Reporting System (APRS) is an amateur radio packet network that has evolved over the last several decades in tandem with, and then arguably beyond, the lifetime of other VHF/UHF amateur packet networks, to the point where it is one of very few packet networks left on the amateur VHF/UHF bands. This is proving to be problematic due to the loss of institutional knowledge as older amateur radio operators who designed and built APRS and other AX.25-based packet networks abandon the hobby or pass away. The purpose of this document is to collect and curate a sufficient body …

Growth Media And Lipid Determination Comparison Of High Rate Algae Ponds, Eric Alexander Nicolai

Growth Media and Lipid Determination Comparison

of High Rate Algae Ponds

Eric Alexander Nicolai

The feasibility of algal biofuel production relies on the use of a non-potable water source. Municipal wastewater is nutrient-rich and a cost effective option as a growth media in algae ponds. However, this resource may be too valuable for algal biomass production, as reclaimed wastewater is needed for surface irrigation and groundwater recharge. This thesis compares the performance of 4.2 m² high rate algal raceway ponds (HRAPs) to 33 m² HRAPs grown on primary settled wastewater during a media recycling study and a growth …

Bridging Structure And Function In Semi-Arid Ecosystems By Integrating Remote Sensing And Ground Based Measurements, Dan J. Krofcheck

Biology ETDs

The Southwestern US is projected to continue the current significant warming trend, with increased variability in the timing and magnitude of rainfall events. The effects of these changes in climate are already evident in the form of multi-year droughts which have resulted in the widespread mortality of woody vegetation across the region. Therefore, the need to monitor and model forest mortality and carbon dynamics at the landscape and regional scale is an essential component of regional and global climate mitigation strategies, and critical if we are to understand how the imminent state transitions taking place in forests globally will affect …

Community Ecology, Climate Change And Ecohydrology In Desert Grassland And Shrubland, Matthew Daniel Petrie

Biology ETDs

This dissertation explores the climate, ecology and hydrology of Chihuahuan Desert ecosystems in the context of global climate change. In coming decades, the southwestern United States is projected to experience greater temperature-driven aridity, possible small decreases in annual precipitation, and a later onset of summer monsoon rainfall. These changes may have profound consequences for ecological systems in the Chihuahuan Desert, which are intensely water-limited and respond to even small pulses of moisture availability. The first chapter (Chapter 2) compares change in the properties of monsoon season precipitation from 1910-2010 in the northern Chihuahuan Desert region to local variability in monsoon …

Aret: A Novel Regulator Of Alternative Splicing In The Flight Muscle Transcripts In Drosophila Melanogaster, Sandy Thi Oas

Biology ETDs

Drosophila melanogaster has been used as a model organism for understanding muscle development. Drosophila flight and jump muscles are distinct functionally and biochemically. This distinction is due to differentially expressed genes and differentially spliced mRNA transcripts. The exact mechanism of alternative splicing in somatic muscles is not well characterized. Aret was previously shown to be a transcriptional repressor, and has been implicated in splicing regulation based upon literature analysis and preliminary work. This study aims to define the regulatory role of Aret and the impact of alternative splicing on determining muscle diversification and fiber choice. We indicate the importance of …

Comparison Of Upper Tropospheric Carbon Monoxide From Mopitt, Ace-Fts, And Hippo-Qcls, Sara Martínez-Alonzo, Merritt N. Deeter, Helen M. Worden, John C. Gille, Louisa K. Emmons, Laura L. Pan, Mijeong Park, Gloria L. Manney, Peter F. Bernath, Chris D. Boone

Chemistry & Biochemistry Faculty Publications

Products from the Measurements Of Pollution In The Troposphere (MOPITT) instrument are regularly validated using in situ airborne measurements. However, few of these measurements reach into the upper troposphere, thus hindering MOPITT validation in that region. Here we evaluate upper tropospheric (~500 hPa to the tropopause) MOPITT CO profiles by comparing them to satellite Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) retrievals and to measurements from the High-performance Instrumented Airborne Platform for Environmental Research Pole to Pole Observations (HIPPO) Quantum Cascade Laser Spectrometer (QCLS). Direct comparison of colocated v5 MOPITT thermal infrared-only retrievals, v3.0 ACE-FTS retrievals, and HIPPO-QCLS measurements shows …

Majorana Fermions In Chiral Topological Superconductors, Eugen Florin Dumitrescu

All Dissertations

Majorana fermions were first proposed in the context of high energy physics by Ettore Majorana in 1937, just before his mysterious disappearance. Now, over 70 years later, signatures of condensed matter ana-logues of Majorana fermions are finally appearing in low-dimensional superconductor-based heterostructures. In low-dimensional systems, these order parameter, defect-bound Majorana quasiparticles obey non-Abelian quantum statistics and can therefore be used as the building blocks of a topological quantum computer. In this thesis we will analyze the signatures associated with, and the robustness of, Majorana bound states in a variety of one-dimensional superconducting platforms. Our main result is the finding that …

Issues In Central Bank Communication, Williams D. Kareem

Bullion

This article examines salient issues in communication which is a key aspect of Central Banking. Although, the value of communication has been hitherto ignored, it has become evident over time that, for a central bank to succeed in achieving its set objectives and mandates, it must put in place effective and efficient mechanisms needed in crafting, and disseminating information about its policies. The ability of the central banks to identify their stakeholders and address their unique communication needs will enable them to earn the trust of their stakeholders and portray them as transparent and accountable entities.

A Simple Adjustment For Bandwidth Snooping, Timothy B. Armstrong, Michal Kolesár

Cowles Foundation Discussion Papers

Kernel-based estimators are often evaluated at multiple bandwidths as a form of sensitivity analysis. However, if in the reported results, a researcher selects the bandwidth based on this analysis, the associated confidence intervals may not have correct coverage, even if the estimator is unbiased. This paper proposes a simple adjustment that gives correct coverage in such situations: replace the Normal quantile with a critical value that depends only on the kernel and ratio of the maximum and minimum bandwidths the researcher has entertained. We tabulate these critical values and quantify the loss in coverage for conventional confidence intervals. For a …

True Limit Distributions Of The Anderson-Hsiao Iv Estimators In Panel Autoregression, Peter C.B. Phillips, Chirok Han

Cowles Foundation Discussion Papers

This note derives the correct limit distributions of the Anderson Hsiao (1981) levels and differences instrumental variable estimators, provides comparisons showing that the levels IV estimator has uniformly smaller variance asymptotically as the cross section ( n ) and time series ( T ) sample sizes tend to infinity, and compares these results with those of the first difference least squares (FDLS) estimator.

Weak Convergence To Stochastic Integrals For Econometric Applications, Hanying Liang, Peter C.B. Phillips, Hanchao Wang, Qiying Wang

Cowles Foundation Discussion Papers

Limit theory involving stochastic integrals is now widespread in time series econometrics and relies on a few key results on function space weak convergence. In establishing weak convergence of sample covariances to stochastic integrals, the literature commonly uses martingale and semimartingale structures. While these structures have wide relevance, many applications in econometrics involve a cointegration framework where endogeneity and nonlinearity play a major role and lead to complications in the limit theory. This paper explores weak convergence limit theory to stochastic integral functionals in such settings. We use a novel decomposition of sample covariances of functions of I(1) and I(0) …

Intellectual Origins Of (Modern) Substantive Due Process, The, Joshua D. Hawley

Faculty Publications

Almost fifty years after the Supreme Court revived the doctrine, substantive due process remains a puzzle. Detractors insist it is nothing more than judicial policy making. Defenders say it accords with the deepest values of the Constitution. But on all sides, the present scholarly debate suffers from an impoverished understanding of modern substantive due process's intellectual history, which has led to an impoverished understanding of the doctrine's core normative content. It is time for a revisionist turn. This Article supplies that turn by excavating the intellectual origins of modern substantive due process and relating that history to the doctrine's development. …

Plant–Soil Feedbacks Of Exotic Plant Species Across Life Forms: A Meta-Analysis, Annelein Meisner, W. H. Gera Hol, Wietse De Boer, Jennifer Adams Krumins, David A. Wardle, Wim H. Van Der Putten

Department of Biology Faculty Scholarship and Creative Works

Invasive exotic plant species effects on soil biota and processes in their new range can promote or counteract invasions via changed plant–soil feedback interactions to themselves or to native plant species. Recent meta-analyses reveale that soil influenced by native and exotic plant species is affecting growth and performance of natives more strongly than exotics. However, the question is how uniform these responses are across contrasting life forms. Here, we test the hypothesis that life form matters for effects on soil and plant–soil feedback. In a meta-analysis we show that exotics enhanced C cycling, numbers of meso-invertebrates and nematodes, while having …

A Qualitative Study Evaluating Bedside Reporting And The Impact On Nurse Satisfaction And Communication Barriers With Washington Regional Medical Center, Win Szeto, Sarah Wren, Molly Milborn

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Nursing care occurs on a continuum that involves transferring the responsibility of a patient’s care from one nurse to another during shift change. Hand-off reports are a vital part of the communication cycle to ensure safe and effective care. Studies have shown bedside reporting increases patient and nurse satisfaction as well as the nurse-patient relationship (Agency for Healthcare Research and Quality, 2013b). The aim of this study was to educate nurses on the importance of bedside reporting and to implement a standardized hand-off. This study was evaluated through two measures. The first measure involved a survey/interview on nurses' perception before …

Saturated Free Fatty Acids Induce Cholangiocyte Lipoapoptosis, Sathish Kumar Natarajan, Sally A. Ingham, Ashley M. Mohr, Cody J. Wehrkamp, Anuttoma Ray, Sohini Roy, Sophie C. Cazanave, Mary A. Smith, Justin L. Mott

Journal Articles: Biochemistry & Molecular Biology

Recent studies have identified a cholestatic variant of nonalcoholic fatty liver disease (NAFLD) with portal inflammation and ductular reaction. Based on reports of biliary damage, as well as increased circulating free fatty acids (FFAs) in NAFLD, we hypothesized the involvement of cholangiocyte lipoapoptosis as a mechanism of cellular injury. Here, we demonstrate that the saturated FFAs palmitate and stearate induced robust and rapid cell death in cholangiocytes. Palmitate and stearate induced cholangiocyte lipoapoptosis in a concentration-dependent manner in multiple cholangiocyte-derived cell lines. The mechanism of lipoapoptosis relied on the activation of caspase 3/7 activity. There was also a significant up-regulation …

The Double Role Of Ethnic Heterogeneity In Explaining Welfare-State Generosity, Markus Jäntti, Gerald David Jaynes, John E. Roemer

Cowles Foundation Discussion Papers

Based on theoretical models of budget-balanced social insurance and individual choice, we argue that in addition to the well-known empathy mechanism whereby ethnic heterogeneity undermines sentiments of solidarity among a citizenry to reduce welfare generosity, population heterogeneity affects the generosity of a polity’s social insurance programs through another distinct mechanism, political conflict . Ethnic heterogeneity likely intensifies political conflict and reduces welfare generosity because heterogeneity of unemployment risk makes it more difficult to achieve social consensus concerning tax-benefit programs. Utilizing two separate regression analyses covering highly diverse polities, the 50 U.S. states and District of Columbia (CPS data), and 13 …

Asymptotic Size Of Kleibergen's Lm And Conditional Lr Tests For Moment Condition Models, Donald W.K. Andrews, Patrik Guggenberger

Cowles Foundation Discussion Papers

An influential paper by Kleibergen (2005) introduces Lagrange multiplier (LM) and conditional likelihood ratio-like (CLR) tests for nonlinear moment condition models. These procedures aim to have good size performance even when the parameters are unidentified or poorly identified. However, the asymptotic size and similarity (in a uniform sense) of these procedures has not been determined in the literature. This paper does so. This paper shows that the LM test has correct asymptotic size and is asymptotically similar for a suitably chosen parameter space of null distributions. It shows that the CLR tests also have these properties when the dimension p …

The Theoretical And Research Basis Of Co-Constructing Meaning In Dialogue, Janet Beavin Bavelas, Peter De Jong, Sara Smock Jordan, Harry Korman

Journal of Solution Focused Practices

de Shazer (1991) introduced a post-structural view of language in therapy in which the participants' sociai interaction determines the meaning of the words they are using. Broader theories of social construction are similar but lack details about the role of language. This article focuses on the observable details of co-constructing meaning in dialogue. Research in psycholinguistics has provided experimental ev­idence for how speakers and their addressees collaboratively co-construct their dialogues. We review several of the experiments that have demonstrated the in­fluence and importance of the addressee in shaping what the speaker is saying. Building on this research, we present a …

A Taste Of Wittgenstein For Sfbt. 2: Philosophical Investigations, Nick Drury

Journal of Solution Focused Practices

This second of two papers provides an overview of Wittgenstein's later work and life from the perspective of what is called the 'resolute' or 'elucidatory' reading, for Solution-Focused Brief Therapists. This perspective takes the view that Witt­genstein's work can be seen as a form of therapy that enables us to be more at­ tuned to the world and each other.
