Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry

Speech Pathology and Audiology Faculty Research and Publications

This paper introduces a new method to track articulator movements, specifically jaw position and angle, using 5 degree of freedom (5 DOF) orientation data. The approach uses a quaternion rotation method to accomplish this jaw tracking during speech using a single senor on the mandibular incisor. Data were collected using the NDI Wave Speech Research System for one pilot subject with various speech tasks. The degree of jaw rotation from the proposed approach is compared with traditional geometric calculation. Results show that the quaternion based method is able to describe jaw angle trajectory and gives more accurate and smooth estimation …

The Experience Of Homelessness And The Human-Companion Animal Bond : A Quantitative Study : A Project Based Upon An Investigation At San Francisco Community Clinic Consortium/Veterinary Street Outreach Services, San Francisco, California, Erin J. Brewbaker

Theses, Dissertations, and Projects

This qualitative study explores homeless pet owners' perceptions regarding their experience of homelessness and the impact of companion pet accompaniment on this experience. In-person, semi-structured interviews were held with a diverse sample of 12 homeless pet owners receiving services from Veterinary Street Outreach Services (VET SOS), a volunteer-based project providing free veterinary care for the companion animals of homeless individuals in San Francisco. Participant narratives were used to explore the complexities of the experience of homelessness while being accompanied by a companion animal, personal experiences of homelessness, insights concerning the bond shared between companion animals and owner, and the experience …

Responding To Stern V. Marshall, Stephanie J. Bentley

Emory Bankruptcy Developments Journal

Stern v. Marshall is the most recent decision in a series of cases decided by the Supreme Court that involves the doctrine of public rights. The Court found that although 28 U.S.C. § 157(b)(2)(C) permits a bankruptcy court to enter final judgments on all counterclaims, Article III of the Constitution does not. The Court reiterated that Article III, Section 1 of the Constitution mandates the judicial power of the United States "be vested in one Supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish." The judges for these courts must have …

The Paradox Of Political Power: Post-Racialism, Equal Protection, And Democracy, William M. Carter Jr.

Emory Law Journal

Racial minorities have enjoyed increasing electoral success in recent years, while continuing to rank at or near the bottom in terms of health, wealth, income, education, and the effects of the criminal justice system. Some observers, including some members of the Supreme Court, have pointed to evidence of isolated electoral success as proof of "post-racialism," while ignoring the evidence of substantial continued disparities for the vast majority of people of color.

Tax Abuse - Lessons From Abroad, Orly Sulami Mazur

SMU Law Review

How does a government distinguish between tax planning and tax abuse? Most democratic societies agree that citizens have a right to limit their tax liability through tax planning. However, governments generally also agree that this right does not extend to tax abuse. Tax abuse substantially reduces government tax revenues and weakens the integrity of our tax systems and the efficiency of our economy. Thus, making this distinction between tax planning and tax abuse is critical. In an attempt to identify and counter tax abuse and its detrimental effects, the United States recently enacted an anti-abuse rule in Section 7701(o) of …

The People Paradox, Nicole Stelle Garnett

Journal Articles

U.S. land-use regulators are increasingly embracing mixed-land-use “urban” neighborhoods, rather than single-land-use “suburban” ones, as a planning ideal. This shift away from traditional regulatory practice reflects a growing endorsement of Jane Jacobs’s influential argument that mixed-land-use urban neighborhoods are safer and more socially cohesive than single-land-use suburban ones. Proponents of regulatory reforms encouraging greater mixing of residential and commercial land uses, however, completely disregard a sizable empirical literature suggesting that commercial land use generates, rather than suppress, crime and disorder, and that suburban communities have higher levels of social capital than urban communities. This Article constructs a case for mixed-land-use …

Rehabilitation Settings After Joint Replacement: An Application Of Multiattribute Preference Elicitation, Tiffany A. Radcliff, Murray J. Côté, David L. Olson, Debra Liebrecht

Department of Management: Faculty Publications

While advances in medical treatment and technologies have the potential to improve the delivery of health care, their use typically involves making multiple, complex decisions. Patients and their medical providers may share in the decision-making processes and balance a variety of criteria and/or attributes in the pursuit of improved health. This necessitates a stronger understanding of the role of human behavior in health care processes and presents a timely opportunity to use decision analysis tools to contribute to this important aspect of health care operations. This article reports on the application of multiattribute preference elicitation to identify postsurgical rehabilitation setting …

Measuring Implicit Psychological Constructs In Organizational Behavior: An Example Using Psychological Capital, Peter D. Harms, Fred Luthans

Department of Management: Faculty Publications

Implicit psychological constructs are effective predictors of behavioral outcomes but are rarely used in organizational settings because of real or imagined problems with measurement validity and administration. To address these concerns, we present a means of assessing implicit constructs quickly and easily by using psychological capital as an example.

Impact Of Employees’ Character Strengths Of Wisdom On Stress And Creative Performance, James B. Avey, Fred Luthans, Sean T. Hannah, David Sweetman, Christopher Peterson

Department of Management: Faculty Publications

Both conventional understanding and positive psychology recognise an important link between people’s character strengths and how they perform their jobs. However, no research to date has focused on the relationship of employees’ wisdom strengths, potential mediating effects and creative task performance. Utilising a large heterogeneous sample (N = 974) of working adults, this study found that participants’ levels of the character strengths of wisdom were positively related to their performance on a creative task and negatively related to their reported level of stress. In addition, stress was found to be negatively related to creative task performance, with reported stress partly …

Nepetalactones From Essential Oil Of Nepeta Cataria Represent A Stable Fly Feeding And Oviposition Repellent, J. J. Zhu, Dennis R. Berkebile, C. E. Dunlap, A. Zhang, D. Boxler, K. Tangtrakulwanich, R. Behle, Frederick P. Baxendale, Gary J. Brewer

Department of Entomology: Faculty Publications

The stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), is one of the most serious pests to livestock. It feeds mainly on cattle and causes significant economic losses in the cattle industry. Standard stable fly control involving insecticides and sanitation is usually costly and often has limited effectiveness. As we continue to evaluate and develop safer fly control strategies, the present study reports on the effectiveness of catnip (Nepeta cataria L.) oil and its constituent compounds, nepetalactones, as stable fly repellents. The essential oil of catnip reduced the feeding of stable flies by >96% in an in vitro bioassay system, …

The Soybean Aphid, Aphis Glycines (Hemiptera: Aphididae): Population Dynamics On Edamame Soybeans In Nebraska, Usa, Bamphitlhi Tiroesele, Thomas E. Hunt, Robert J. Wright, Erin E. Blankenship, John E. Foster

Department of Entomology: Faculty Publications

Edamame are soybeans harvested at a physiologically immature (R6) stage as a specialty food item for fresh and processed (frozen) markets. The soybean aphid, Aphis glycines Matsumura, is a newly introduced insect pest of soybeans in North America. This field study was to provide baseline information on the impact of A. glycines on the edamame soybean. This study determined the population growth rate of A. glycines on two edamame soybean cultivars, ‘Butterbeans’ and ‘Envy,’ at two planting dates during 2004 and 2005 in Nebraska. Aphid population growth was significantly higher on 'Butterbeans' than on 'Envy' for the first planting date …

Using Sex Pheromone Traps In The Decision-Making Process For Pesticide Application Against Fall Armyworm (Spodoptera Frugiperda [Smith] [Lepidoptera: Noctuidae]) Larvae In Maize, Ivan Cruz, Maria De Lourdes Corrêa Figueiredo, Rafael Braga Da Silva, Ivana Fernandes Da Silva, Cristiane De Souza Paula, John E. Foster

Department of Entomology: Faculty Publications

The fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), is a major pest of maize and frequently demands control measures. The timing of insecticide application is a key factor in determining its efficiency, so an experiment was designed to investigate this. Application of insecticide was based on three criteria: (i) the number of trap-caught moths in a Delta-type trap with a commercial sex pheromone lure placed in the center of the target area, soon after plant emergence; (ii) the percentage of plants exhibiting pinhole-type damage (10% or 20%), and (iii) the percentage of plants exhibiting shot hole–type damage (10% or 20%) …

Comparative Toxicity Of Acaricides To Honey Bee (Hymenoptera: Apidae) Workers And Queens, Lizette Dahlgren, Reed M. Johnson, Blair D. Siegfried, Marion D. Ellis

Department of Entomology: Faculty Publications

Acaricides are used to treat honey bee (Apis mellifera L.) colonies to control the varroa mite (Varroa destructor Anderson & Trueman), a worldwide threat to honey bee health. Although acaricides control a serious honey bee parasite and mitigate bee loss, they may cause harm to bees as well. We topically applied five acaricides, each with a different mode of action, to young adult queen and worker bees to generate dose-response curves and LD₅₀. Twenty-four hours after treatment, queens were found to be three times more tolerant of tau-fluvalinate and six times more tolerant of thymol than …

Human Risk Of Infection With Borrelia Burgdorferi, The Lyme Disease Agent, In Eastern United States, Maria A. Diuk-Wasser, Anne Gatewood Hoen, Paul Cislo, Robert Brinkerhoff, Sarah A. Hamer, Michelle Rowland, Roberto Cortinas, Gwenaël Vourc’H, Forrest S. Melton, Graham J. Hickling, Jean I. Tsao, Jonas Bunikis, Alan G. Barbour, Uriel Kitron, Joseph Piesman, Durland Fish

Department of Entomology: Faculty Publications

The geographic pattern of human risk for infection with Borrelia burgdorferi sensu stricto, the tick-borne pathogen that causes Lyme disease, was mapped for the eastern United States. The map is based on standardized field sampling in 304 sites of the density of Ixodes scapularis host-seeking nymphs infected with B. burgdorferi, which is closely associated with human infection risk. Risk factors for the presence and density of infected nymphs were used to model a continuous 8 km × 8 km resolution predictive surface of human risk, including confidence intervals for each pixel. Discontinuous Lyme disease risk foci were identified in …

Using Video-Tracking To Assess Sublethal Effects Of Pesticides On Honey Bees (Apis Mellifera L.), Bethany S. Teeters, Reed M. Johnson, Marion D. Ellis, Blair D. Siegfried

Department of Entomology: Faculty Publications

Concern about the role of pesticides in honey bee decline has highlighted the need to examine the effects of sublethal exposure on bee behaviors. The video-tracking system EthoVisionXT (Noldus Information Technologies) was used to measure the effects of sublethal exposure to tau-fluvalinate and imidacloprid on honey bee locomotion, interactions, and time spent near a food source over a 24-h observation period. Bees were either treated topically with 0.3, 1.5, and 3 μg tau-fluvalinate or exposed to 0.05, 0.5, 5.0, 50, and 500 ppb imidacloprid in a sugar agar cube. Tau-fluvalinate caused a significant reduction in distance moved at all dose …

Roles In A Networked Software Development Ecosystem: A Case Study In Github, Patrick Wagstrom, Corey Jergensen, Anita Sarma

School of Computing: Technical Reports

Open source software development has evolved beyond single projects into complex networked ecosystems of projects that share portions of their code, social norms, and developer communities. This networked nature allows developers moving into a new project to easily leverage knowledge about process and social norms along with reputation gained in related projects. In this paper we examine a subset of the communities found in GitHub, a large software development community that focuses on “social coding”. We identify a variety of roles in the ecosystem that go beyond the previous user/developer dichotomy and find that these roles often persist across sub-communities …

A Preliminary Model For Comfortable Approach Distance Based On Environmental Conditions And Personal Factors, Brittany Duncan, Robin R. Murphy

School of Computing: Conference and Workshop Papers

This paper presents a model of “comfortable distance” that captures the factors and conditions known to affect personal space in human-human and human-robot interactions, as well as any identified relationships between them. In the first known human-robot interaction (HRI) survey on approach distance, 19 papers were reviewed and the “comfortable distance” model was synthesized with three distinct types of inputs: environmental conditions, personal factors, and agent factors. Five environmental conditions (lighting, ceiling height, indoor/outdoor, room size, and barrier height) and seven personal factors (gender, age, mood, personality, pet ownership, robot experience, and sitting/standing) structure the model, with four agent factors …

Improving Student Attitudes About Learning Science And Student Scientific Reasoning Skills, Douglas K. Duncan, Leilani Arthurs

Department of Earth and Atmospheric Sciences: Faculty Publications

Student attitudes about learning science and student ideas about the nature of science were compared at the end of two astronomy courses taught in Fall 2007, a course with a traditional astronomy curriculum and a transformed course, whose traditional astronomy curriculum was supplemented by an embedded curriculum that explicitly addressed the nature of science and student metacognition (i.e., thinking about one’s own thinking.) The embedded curriculum in the transformed course gave students practice at evaluating examples of valid science and pseudoscience found on the internet; it also provided students opportunities to discuss what they think about learning science. Student attitudes …

Quantification Of Salt Dust Pathways From A Groundwater-Fed Lake: Implications For Solute Budgets And Dust Emission Rates, Vitaly A. Zlotnik, John B. Ong, John D. Lenters, Jens Schmieder, Sherilyn C. Fritz

Department of Earth and Atmospheric Sciences: Faculty Publications

Emissions of salt dust from the shores of saline lakes significantly impact lake chemistry, air quality, transportation, human health, and climate. Quantitative methods for assessing these emissions, however, are still in the developmental stage. We investigate salt pathways from groundwater to dust using an approach that takes advantage of opportune conditions at a groundwater-fed, saline lake in the Nebraska Sand Hills region. The mass of salt in the lakeshore surface crust and soil was measured, as well as in the dust on the surrounding dune field. These data, together with information on the lake hydrology, show that dust emission is …

Imbalance Fault Detection Of Direct-Drive Wind Turbines Using Generator Current Signals, Xiang Gong, Wei Qiao

Department of Electrical and Computer Engineering: Faculty Publications

Imbalance faults constitute a significant portion of all faults in wind turbine generators (WTGs). WTG imbalance fault detection using generator current measurements has advantages over traditional vibration-based methods in terms of cost, implementation, and system reliability. However, there are challenges in using current signals for imbalance fault detection due to low signal-to-noise ratio of the useful information in current signals and non-stationary characteristic frequencies of imbalance faults. This paper proposes a method of using generator stator currents for imbalance fault detection of direct-drive WTGs. In the proposed method, the variable shaft rotating frequency of a WTG is estimated from one …

Analysis Of Π-Phase-Shifted Fiber Bragg Gratings For Ultrasonic Detection, Tongqing Liu, Ming Han

Department of Electrical and Computer Engineering: Faculty Publications

Using numerical simulations, we investigated the responses of the π-phase-shifted fiber Bragg gratings (πFBGs) impinged by pressure ultrasonic waves. The effect of the grating length, grating refractive index modification depth, and ultrasonic frequency on the wavelength sensitivity and intensity sensitivity of the πFBG ultrasonic sensor for ultrasonic waves of different wavelengths was analyzed. The directivity of a πFBG sensor was also studied. Our analysis revealed several unique πFBG response characteristics and will be useful in the design and optimization of fiber-optic ultrasonic sensors that use a πFBG as the sensing element.

A Low-Cost, Reliable, High-Throughput System For Rodent Behavioral Phenotyping In A Home Cage Environment, Steven A. Parkison, Jay D. Carlson, Tammy R. Chaudoin, Traci A. Hoke, A. Katrin Schenk, Evan H. Goulding, Lance C. Pérez, Stephen J. Bonasera

Department of Electrical and Computer Engineering: Faculty Publications

Inexpensive, high-throughput, low maintenance systems for precise temporal and spatial measurement of mouse home cage behavior (including movement, feeding, and drinking) are required to evaluate products from large scale pharmaceutical design and genetic lesion programs. These measurements are also required to interpret results from more focused behavioral assays. We describe the design and validation of a highly-scalable, reliable mouse home cage behavioral monitoring system modeled on a previously described, one-ofa- kind system [1]. Mouse position was determined by solving static equilibrium equations describing the force and torques acting on the system strain gauges; feeding events were detected by a photobeam …

(Im)Mobile Metaphors: Toward An Intersectional Rhetorical History, Carly S. Woods

Department of Communication Studies: Faculty Publications

Metaphors not only "structure our experience" but "by organizing reality in particular ways, our selected metaphors also prescribe how we are to act." As the opening chapter of this volume notes, feminist scholars have long grappled with the figurative language of intersectionality in order to find the conceptual framing that best accounts for varied relationships between power, oppression, and privilege. Similarly, rhetorical historians have an obligation to think critically about the metaphors we use. One cluster of metaphors, in particular, characterizes both intersectional and rhetorical-historical research: the spatial and geographic. Moreover, critiques of both research approaches essentially point to the …

An Examination Of Privacy Rules For Academic Advisors And College Student-Athletes: A Communication Privacy Management Perspective, Jason Thompson, Sandra Petronio, Dawn O. Braithwaite

Department of Communication Studies: Faculty Publications

This study explored how academic advisors managed revealed private information from college student-athletes. The 37 academic advisors were interviewed to address: What criteria advisors use to judge privacy rules regulating access or protection of shared private information from student-athletes, and how privacy-rule choices function in this context? Academic advisors interviewed represented 21 different institutions of the four NCAA division levels and 10 separate athletic conferences. Using Communication Privacy Management theory as a framework, findings indicated there were two main criteria: motivations and risk-benefit ratios used to develop privacy rules managing revealing and concealing the student-athlete’s private information.
