The Arm Motion (Amd) Detection Test, Maria C. Bengston, Leigh A. Mrotek, Tina M. Stoeckmann, Claude Ghez, Robert A. Scheidt

Biomedical Engineering Faculty Research and Publications

Stroke can lead to sensory deficits that impair functional control of arm movements. Here we describe a simple test of arm motion detection (AMD) that provides an objective, quantitative measure of movement perception related proprioceptive capabilities in the arm. Seven stroke survivors and thirteen neurologically intact control subjects performed the AMD test. In a series of ten trials that took less than 15 minutes to complete, participants used a two-button user interface to adjust the magnitude of hand displacements produced by a horizontal planar robot until the motions were just perceptible (i.e. on the threshold of detection). The standard deviation …

Characterization Of A Human Powered Nebulizer Compressor For Resource Poor Settings, Christopher J. Hallberg, Mary Therese Lysaught, Christopher E. Zmudka, William K. Kopesky, Lars E. Olson

Biomedical Engineering Faculty Research and Publications

Background

Respiratory disease accounts for three of the ten leading causes of death worldwide. Many of these diseases can be treated and diagnosed using a nebulizer. Nebulizers can also be used to safely and efficiently deliver vaccines. Unfortunately, commercially available nebulizers are not designed for use in regions of the world where lung disease is most prevalent: they are electricity-dependent, cost-prohibitive, and not built to be reliable in harsh operating conditions or under frequent use.

To overcome these limitations, the Human Powered Nebulizer compressor (HPN) was developed. The HPN does not require electricity; instead airflow is generated manually through a …

Questions/purposes

Which design and material factors are associated with differences in clinical wear performance (implant wear and periprosthetic tissue response) of (1) lumbar and (2) cervical total disc replacements?

Methods

We performed a systematic review on the topics of implant wear and periprosthetic tissue response using an advanced search in MEDLINE and Scopus …

Evaluation Of Upper Extremity Movement Characteristics During Standardized Pediatric Functional Assessment With A Kinect®-Based Markerless Motion Analysis System, Jacob R. Rammer, Joseph J. Krzak, Susan A. Riedel, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

A recently developed and evaluated upper extremity (UE) markerless motion analysis system based on the Microsoft® Kinect® has potential for improving functional assessment of patients with hemiplegic cerebral palsy. 12 typically-developing adolescents ages 12-17 were evaluated using both the Kinect-based system and the Shriners Hospitals for Children Upper Extremity Evaluation (SHUEE), a validated measure of UE motion. The study established population means of UE kinematic parameters for each activity. Statistical correlation analysis was used to identify key kinematic metrics used to develop automatic scoring algorithms. The Kinect motion analysis platform is technically sound and can be applied to standardized task-based …

African American And Hispanic Stem Students' Engagement At Predominantly White Institutions, Terrell Lamont Strayhorn, Fei Bie, Leroy L. Long Iii, Blossom A. Barrett

Publications

Although research has shown that involvement is a helpful predictor of students’ future success, underrepresented minorities (i.e., African Americans and Hispanics) face unique obstacles at predominantly White institutions, which limit their engagement in educationally purposeful activities. Survey data from a 2007 administration of the National Survey of Student Engagement (NSSE) were analyzed to measure African American and Hispanic students’ engagement in educationally purposeful activities. Results from the present study found that student satisfaction in college is positively related to time spent preparing for class and frequency of interactions with faculty members about careers. Furthermore, African American and Hispanic science, technology, …

The Child-Welfare System And The Limits Of Determinacy, Clare Huntington

Faculty Scholarship

To read Robert Mnookin’s seminal 1975 article, Child-Custody Adjudication: Judicial Functions in the Face of Indeterminacy, is to see a blueprint for legislative action. To a remarkable degree, the reforms Mnookin proposed to the child-welfare system are what Congress and the states adopted in the following two decades. And yet reading Mnookin’s article is also a Groundhog Day experience. The problems he described with the child-welfare system nearly forty years ago sound all too familiar today.

Mnookin famously argued that the best-interests standard was indeterminate in the context of the child-welfare system. According to Mnookin, this open-ended standard created …

The Effectiveness Of The Concordance-Discordance Model: Identifying Learning Disabilities In School-Aged Children, Bryan Hendricks

PCOM Psychology Dissertations

After the reauthorization of Individuals with Disabilities Education Act (IDEA) in
2004, the federal regulations indicated that there are three possible methods for the identification of a Specific Learning Disability (SLD). The three methods include the ability-achievement discrepancy (AAD), Response to Intervention (RTI), and the addition of a third method, which consists of other alternative research-based procedures. Hale and Fiorello (2004) proposed the use of a Concordance-Discordance Model (CDM), which suggests that learning disabled students have discordance between processing strength and both processing weakness and achievement deficit. In addition, SLD students have a concordance between the achievement deficit and processing …

Lqts: Gender Differences And Mother-Son Vs. Mother-Daughter, Thea Gallagher

PCOM Psychology Dissertations

Long QT syndrome is a chronic disorder, and one of the most common genetic arrhythmia syndromes that can cause unexpected cardiac arrest and death in individuals. Treatment options include medications, use of implantable cardioverter defibrillators (ICD) and restricting activities of daily life. Minimal research exists exploring the specific psychosocial aspects of the illness and/or the impact on the quality of life of individuals and families coping with the management and diagnosis of this illness. Furthermore, little research has attempted to understand the role of gender differences and mother-child perceptions among individuals with Long QT syndrome. The current study used data …

Improving Cognitive-Behavioral Therapy Homework Adherence With Change Talk And Commitment Language: A Cognitive Dissonance Perspective Of Behavioral Change, Robert J. Brecher

PCOM Psychology Dissertations

Adherence to homework assigned during cognitive-behavioral therapy (CBT) is an important factor contributing to positive outcomes. However, rates of adherence are poor, limited evidence supporting methods to improve adherence is limited. The current study aimed to develop and test an intervention designed to promote CBT homework adherence based on cognitive dissonance theory. Patients participating in outpatient CBT were randomly assigned to either an experimental or a control condition. In the experimental condition, participants engaged in an induced-compliance procedure eliciting change talk targeting the recommended homework activity. The control condition consisted of treatment as usual. Owing to limited sample size (n …

Child-Custody Decisionmaking, Katharine T. Bartlett, Elizabeth S. Scott

Faculty Scholarship

The most famous article on child-custody law, and one of the most important in family law scholarship altogether, is Robert H. Mnookin's Child Custody Adjudication: Judicial Functions in the Face of Indeterminacy, published in Law and Contemporary Problems in 1975. In that article, Professor Mnookin analyzed the best-interests-of-the-child standard, which by the 1970s had emerged as the dominant custody decision rule. Although the best-interests standard seemed on its face to be an uncomplicated and straightforward way to put the interests of children first in custody decisionmaking, Professor Mnookin explained its distinctive character and deficiencies as a legal rule. His …

The Mirror Image Of Asylums And Prisons, Sacha Raoult, Bernard E. Harcourt

Faculty Scholarship

This article analyzes trends in prison rates and mental hospital rates in France since the earliest available statistics. It shows that, on almost two centuries of data and amidst an agitated political history, every asylum trend in France is "countered" by an inverse prison trend, and vice-versa. Both trends are like a mirror image of each other. We reflect on the possible explanations for this intriguing fact and show that the most obvious ones (a population transfer or a building transfer) are not able to account for most of the relationship. After these explanations have been dismissed, we are left …

Governing, Exchanging, Securing: Big Data And The Production Of Digital Knowledge, Bernard E. Harcourt

Faculty Scholarship

The emergence of Big Data challenges the conventional boundaries between governing, exchange, and security. It ambiguates the lines between commerce and surveillance, between governing and exchanging, between democracy and the police state. The new digital knowledge reproduces consuming subjects who wittingly or unwittingly allow themselves to be watched, tracked, linked and predicted in a blurred amalgam of commercial and governmental projects. Linking back and forth from consumer data to government information to social media, these new webs of information become available to anyone who can purchase the information. How is it that governmental, commercial and security interests have converged, coincided, …

Judicial Leadership In Family Court: A Cautionary Tale, Jane M. Spinak

Faculty Scholarship

For the past 35 years I have been practicing in, teaching, and writing about the Family Court. The problem-solving court movement in the last two decades – with its proliferation of drug courts, mental health courts, and veterans courts, to name a few – renewed my interest in the historical roots of the family court because of the parallels between the original juvenile court and the recent problem solving court movement. One of the key elements – perhaps the defining element – in both is the role of the judge as the leader of the court. That is what I …

Exposure To Btex And Assessment Of The Potential Risk Among Pregnant Residents Living In The Vicinity Of A Petro-Chemical Industrial Estate, Santi Keadthongthawee, Nipa Maharachpong, Sirirat Chanvaivit, Nalinee Sripaung, Nantaporn Phatrabuddha

Applied Environmental Research

This research was conducted to estimate exposure and risk of exposure to BTEX (benzene, toluene, ethylbenzene and xylene)by a cross-sectional studying among pregnant women who lived in the vicinity of a petro-chemical industrial estatearea. Personal exposure was monitored by environmental and biological sampling.Other relevant data were gathered by a structured questionnaire for analysis. The relationship between BTEX exposure and potential risk factors was determined by multiple linear regression. Average BTEX exposure levels were 18.89, 29.40, 10.26, and 17.85µg m-3, respectively, which were significantlyhigher than the control group. Urinary metabolite levels of muconic acid(t,t-MA), hippuric acid (HA),mandelic acid (MA), andmethyl-hippuric acid …

Another Look At The Root Of The Angiosperms Reveals A Familiar Tale, Bryan T. Drew, Brad R. Ruhfel, Stephen A. Smith, Michael J. Moore, Barbara G. Briggs, Matthew A. Gitzendanner, Pamela S. Soltis, Douglas E. Soltis

Faculty & Staff Scholarship

Since the advent of molecular phylogenetics more than 25 years ago, a major goal of plant systematists has been to discern the root of the angiosperms. While most studies indicate that Amborella trichopoda is sister to all remaining extant flowering plants, support for this position has varied with respect to both the sequence data sets and analyses employed. Recently, Goremykin et al. (2013) questioned the “Amborella-sister hypothesis” using a “noise-reduction” approach and reported a topology with Amborella + Nymphaeales (water lilies) sister to all remaining angiosperms. Through a series of analyses of both plastid genomes and mitochondrial genes, we continue …

An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli

Psychology Faculty Research and Publications

Recently research on the relationship between stress and cognition, emotion, and behavior has greatly increased. These advances have yielded insights into important questions ranging from the nature of stress' influence on addiction1 to the role of stress in neural changes associated with alterations in decision-making^2,3. As topics being examined by the field evolve, however, so too must the methodologies involved. In this article a practical and effective alternative to a classic stress induction technique, the cold pressor test (CPT), is presented: the cold pressor arm wrap (CPAW). CPT typically involves immersion of a participant's dominant hand in ice-cold …

Nuisance American Alligators: An Investigation Into Trends And Public Opinion, Cord B. Eversol, Scott E. Henke, Jacob L. Ogdee, David B. Wester, Amos Cooper

Human–Wildlife Interactions

The population rebound of the American alligator (Alligator mississippiensis; hereafter, alligator), with the rapid growth of populations throughout its range, has caused an influx of human–alligator conflicts. We quantified 5,838 nuisance alligator reports from 2000 to 2011 to develop more site-specific strategies of management and to determine where management should be focused to minimize the conflict. We also surveyed the general public’s attitude toward and knowledge of alligators (n = 98) as a technique to better understand human dimensions of nuisance alligator management in Texas. Counties that received the largest numbers of nuisance alligator reports were Jefferson (16%), Fort Bend …

Determination Of Residue Levels Of Alpha-Chloralose In Duck Tissues, David A. Goldade, Randal S. Stahl, John. J. Johnston

Human–Wildlife Interactions

Alpha-chloralose (AC) is used to capture nuisance waterfowl so that they can be relocated. Concerns for food safety limit its use prior to or during the waterfowl hunting season. To determine its half-life in tissue, we administered AC to adult male (n = 7) and female (n = 5) mallard ducks (Anas platyrhynchos) via oral gavage. A gel capsule containing 100 μCi of radioactive AC (14C-AC) and sufficient nonlabeled AC to produce a dose of approximately 30 mg/kg was given to each duck.The ducks were euthanized at 2, 6, 10, and 18 hours postdosing …

Chipman, Todd Atwood, Tyler Cozzens, Frank Fillo, Robert Hale, Brody Hatch, Joanne Maki, Olin E. Rhodes, Erin E. Rees, Charles E. Rupprecht, Rowland Tinline, Kurt C. Vercauteren, Dennis Slate

Human–Wildlife Interactions

The Centers for Disease Control (CDC) and USDA Wildlife Services (WS) have been involved in an oral rabies vaccination (ORV) program for raccoons (Procyon lotor) that has slowed the westward spread of raccoon rabies. The objective of this study was to forecast the spread of the disease if an ORV zone was not maintained. A group decision-making process was designed to address the forecasting problem and was implemented using a group of 15 experts and 4 support personnel at a meeting at the USDA National Wildlife Research Center. Ten expansion regions were constructed that described the spread of …

Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox

Human–Wildlife Interactions

Feral cats (Felis catus) are abundant in many parts of the world and pose a threat to native wildlife. Human–wildlife conflicts regarding how feral cats should be managed have increased recently. In Hawaii, previous research has revealed that most residents would like to see the feral cat abundance reduced, but opinions differ regarding which techniques are acceptable for achieving this. This paper describes an analytical hierarchy process that combines rankings of decision criteria by Hawaii’s residents with expert knowledge of the costs and benefits associated with 7 techniques (live-capture and adoption, live-capture and lethal injection, live-capture and lethal gunshot, trap-neuter-release …

American Black Bear–Apiary Conflicts In Michigan, Beverly K. Mckinley, Jerrold L. Belant, Dwayne R. Etter

Human–Wildlife Interactions

American black bear (Ursus americanus) damage to apiaries can result in substantial economic loss. We used records of black–bear apiary conflicts collected by the Michigan Department of Natural Resources to characterize damage in the Upper and Northern Lower peninsulas of Michigan from April 2003 to May 2011. Most conflicts occurred between May and July, and the number of conflicts decreased across years. The number of reported conflicts was directly correlated with bear population size. However, we found no positive association between numbers of reported conflicts with bear condition as indexed by winter severity and hive abundance. Intolerance toward …

Wildlife Strikes With U.S. Military Rotary-Wing Aircraft Deployed In Foreign Countries, Brian E. Washburn, Paul J. Cisar, Travis L. Devault

Human–Wildlife Interactions

During recent decades, rotary-wing aircraft (helicopters) within the U.S. Department of Defense (e.g., U.S Army and U.S. Air Force) have been deployed overseas to conduct a variety of noncombat and combat missions. Our objective was to conduct a comprehensive analysis of wildlife (birds, bats, insects) strikes with U.S. Army and U.S. Air Force rotarywing aircraft during overseas deployments. We acquired all available wildlife strike information involving U.S. Army and U.S. Air Force military rotary-wing aircraft engaged in flight operations associated with U.S. military bases around the world during 1990 to 2011. Wildlife strikes with military rotary-wing aircraft occurred in >31 …

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball

Human–Wildlife Interactions

We examined the repellency of a commercially available animal repellent to determine the efficacy of its application to objects that are attractive to coyotes (Canis latrans). Specifically, we aimed to both prevent chewing behavior by coyotes on a nylon-like strapping material, which is used to construct barrier-arresting systems on military airstrips, and determine the ability of the solution to prevent the animals from repeating the undesired behavior. We mixed Ropel® Animal and Rodent Repellent with a liquid latex sticker to form a 2% latex and 98% Ropel solution. We used a 2% latex and 98% water solution as …
