Using Virtual Reality And Web Conferencing Technologies: Exploring Alternatives For Microteaching In A Rural Region, Raymond A. Dixon, Cassidy Hall, Farjahan Shawon Jan 2019

Using Virtual Reality And Web Conferencing Technologies: Exploring Alternatives For Microteaching In A Rural Region, Raymond A. Dixon, Cassidy Hall, Farjahan Shawon

Northwest Journal of Teacher Education

Preservice teachers’ views of two types of technologies which provided realistic environments in which to practice microteaching are described: (1) TLE TeachLivE™ Lab, a virtual reality environment that employs avatars as students in a virtual classroom, and (2) web conferencing technology to synchronously teach students in remotely located classrooms. Preservice teachers opined that each technology offers a relatively realistic environment that allows them to interact with virtual and real students. Microteaching through these technologies increases their self-confidence and provided a safe, non-threatening environment for them to reflect on their practice. We concluded these emerging technologies can provide viable alternatives to …


In Vitro Bioaccessibility Of Novel Low-Crystallinity Phytosterol Nanoparticles In Non-Fat And Regular-Fat Foods, Ali Ubeyitogullari, Ozan Ciftci Jan 2019

In Vitro Bioaccessibility Of Novel Low-Crystallinity Phytosterol Nanoparticles In Non-Fat And Regular-Fat Foods, Ali Ubeyitogullari, Ozan Ciftci

Department of Food Science and Technology: Faculty Publications

Crystalline structure of phytosterols leads to poor bioavailability and makes their incorporation into foods challenging. Bioaccessibility of first-of-their-kind low-crystallinity phytosterol nanoparticles impregnated in nanoporous starch aerogels (PS-NSA) was evaluated in non-, low-, and regular-fat solid and aqueous food formulations, namely, granola bars and puddings for the first time. Bioaccessibility of the phytosterol nanoparticles was significantly higher than that of crude phytosterols in all food formulations (p < .05); it was 88.2 and 91.8% for low- or regular-fat granola bars, respectively, whereas bioaccessibility of crude phytosterols was ca. 30% in those formulations. However, decreasing the lipid content to zero resulted in lower phytosterols' bioaccessibilities from both PS-NSA (53%) and crude phytosterols (ca. 16%) in non-fat granola bars. Bioaccessibility of crude phytosterols (2%) was significantly enhanced with PS-NSA (19%) in the pudding formulation. PS-NSA allows preparation of low- and non-fat foods enriched with phytosterols while enhancing the health benefits of phytosterols with smaller doses.


Radical Vulnerability, Richa Nagar, Roozbeh Shirazi Jan 2019

Radical Vulnerability, Richa Nagar, Roozbeh Shirazi

Study of Women, Gender, & Sexuality: Faculty Publications

The co‐constitutive concepts of radical vulnerability, situated solidarities, and hungry translations are rooted in evolving journeys of saathis of Sangtin Kisan Mazdoor Sangathan or SKMS, a movement of 8000 small kisans and mazdoors in Sitapur District of Uttar Pradesh in India that emerged from the battles summarised in Playing with Fire and Muddying the Waters. Radical vulnerability seeks to reimagine the temporalities and meanings of knowledge‐making partnerships by surrendering to a politics of co‐travelling and co‐authorship, politics that are accompanied by difficult refusals. A relationality embedded in radical vulnerability strives to internalise that our self is intensely co‐constituted and entangled …


Evaluation Of The Impact Of A Low Dose Subcutaneous Lignocaine And Ketamine Infusion Utilising Nerve Excitability Studies In A Chronic Migraine Population., Christopher Rofe Jan 2019

Evaluation Of The Impact Of A Low Dose Subcutaneous Lignocaine And Ketamine Infusion Utilising Nerve Excitability Studies In A Chronic Migraine Population., Christopher Rofe

Theses

Migraine is a common condition in which the diagnosis is based on clinical grounds. There is no clinically available biophysical marker that can evaluate migraine. Migraines are linked to functional brain changes in the absence of structural abnormalities. A clinically useful tool capable of evaluating functional changes in patients with migraine could be used to aid diagnosis and management.

Patients with chronic migraine have frequent or continuous headache which is accompanied by significant morbidity. There are limited data available regarding treatment options for curtailment of chronic migraine. In this prospective observational study, patients suffering from chronic migraine underwent a prolonged …


Mark Oliphant And The Invisible College Of The Peaceful Atom, Darren Holden Jan 2019

Mark Oliphant And The Invisible College Of The Peaceful Atom, Darren Holden

Theses

The weapon first created by atomic scientists of the 1940s was unprecedented in its power and potential to kill. Not only can it destroy infrastructure and all living things over a wide area, it leaves a haunting invisible footprint of radiation that can continue to harm long after its heat has dissipated. The atomic bomb was first conceptualised, proven and built by civilian scientists and overseen by an ambitious military and wary bureaucrats. The scientists belligerently lobbied their governments to take the potential of atomic weaponry seriously and it is hence not surprising that they are often portrayed as ghoulishly …


Hemodynamic Interference Of Serial Stenoses And Its Impact On Ffr And Ifr Measurements, Siyeong Ju, Linxia Gu Jan 2019

Hemodynamic Interference Of Serial Stenoses And Its Impact On Ffr And Ifr Measurements, Siyeong Ju, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

The hemodynamic interference of serial stenoses poses challenges for identifying the functional severity using the fractional flow reserve (FFR) method. The instantaneous wave-free ratio (iFR), i.e., the distal-to-proximal pressure ratio at 75% of diastole, was recently proposed to overcome the disadvantages of the FFR. However, the underlying mechanism remained ambiguous due to the lack of quantitative definition of hemodynamic interference. The objective of this study is to quantitatively define the hemodynamic interference and then examine its role on the FFR and iFR measurements. Pressure distributions, velocity fields, and Q-criterion which identifies vortices, were obtained through the computational fluid dynamics (CFD) …

Hemodynamics And Wall Mechanics After Surgical Repair Of Aortic Arch: Implication For Better Clinical Decisions, Siyeong Ju, Ibrahim Abdullah, Shengmao Lin, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

Graft repair of aortic coarctation is commonly used to mimic the physiological aortic arch shape and function. Various graft materials and shapes have been adopted for the surgery. The goal of this work is to quantitatively assess the impact of graft materials and shapes in the hemodynamics and wall mechanics of the restored aortic arch and its correlation with clinical outcomes. A three-dimensional aortic arch model was reconstructed from magnetic resonance images. The fluid–structure interaction (FSI) analysis was performed to characterize the hemodynamics and solid wall mechanics of the repaired aortic arch. Two graft shapes (i.e., a half-moon shape and …

Faculty Publications

Exogenous ketones may provide therapeutic benefit in treatment of obesity. Administration of the ketone ester (KE) R,S-1,3-butanediol acetoacetate diester (BD-AcAc) decreases body weight in mice, but effects on energy balance have not been extensively characterized. The purpose of this investigation was to explore concentration-dependent effects of BD-AcAc on energy intake and expenditure in mice. Forty-two male C57BL/6J mice were randomly assigned to one of seven isocaloric diets ( = 6 per group): (1) Control (CON, 0% KE by kcals); (2) KE5 (5% KE); (3) KE10 (10% KE); (4) KE15 (15% KE); (5) KE20 (20% KE); (6) KE25 (25% KE); and …


Beyond Beholden, Da Lin Jan 2019

Beyond Beholden, Da Lin

Law Faculty Publications

Corporate law has long been concerned with director independence. In controlled companies, the conventional wisdom focuses on "beholdenness" as the main threat to independence. The prevailing theory argues that directors might feel pressured to reciprocate a past kindness from the controlling shareholder or fear retaliation. This Article argues that this conventional narrative is troublingly incomplete. I show that directors are also influenced by the prospect of rewards, or patronage, from the controller.

This Article is the first to identify controlling shareholder patronage as a systemic phenomenon and to explore how anticipation of future patronage can affect director behavior. It presents …

The Effect Of Obstructive Sleep Apnea Screening On Outcomes Of Adult Surgical Patients In A Suburban Hospital, Candice Gray-Cunningham Jan 2019

The Effect Of Obstructive Sleep Apnea Screening On Outcomes Of Adult Surgical Patients In A Suburban Hospital, Candice Gray-Cunningham

DNP Projects

Background: Obstructive sleep apnea (OSA) characteristics are present in up to one-quarter of the U.S. adult population (Fernandez-Bustamante, Bartels, Clavijo, Scott, Kacmar, Bullard, Moss, Henderson, Juarez-Colunga, & Jameson, 2017). It is estimated that 80-90% of patients with moderate to severe OSA have never been diagnosed (Chung, Abdullah, & Liao, 2016a). The high prevalence of OSA combined with low diagnosis rates give rise to an environment with considerable surgical risk, including respiratory failure and cardiac arrhythmias (Kaw, Chung, Pasupuleti, Mehta, Gay, & Hernandez, 2012). Guidelines have been established by the Society of Anesthesia and Sleep (SASM) for preoperative OSA screening in …


What Is The Prevalence Of Adhd In Children Who Were Diagnosed With Neonatal Abstinence Syndrome? A Retrospective Chart Review., Scott Graham Jan 2019

What Is The Prevalence Of Adhd In Children Who Were Diagnosed With Neonatal Abstinence Syndrome? A Retrospective Chart Review., Scott Graham

DNP Projects

Background: Neonatal abstinence syndrome (NAS) is the set of signs and symptoms present in a newborn whose mother was addicted to drugs while pregnant. NAS can occur due to sudden withdrawal from several drugs, including opioids, benzodiazepines, methamphetamines, and caffeine. It can cause many different issues in the newborn, including diarrhea, tremors, fever, and seizures. While these specific signs and symptoms are self-limited, research is showing that these children grow in to childhood and adolescence with increased risk of Attention-Deficit/Hyperactivity Disorder (ADHD), autism, motor dysregulation, and other cognitive and behavioral sequelae.

Purpose: The purpose of this project was to establish …

Field Evaluation Of Tobacco Engineered For High Leaf-Oil Accumulation, James Perry Jan 2019

Field Evaluation Of Tobacco Engineered For High Leaf-Oil Accumulation, James Perry

Theses and Dissertations--Plant and Soil Sciences

The biofuel market is dominated by ethanol and biodiesel derived from cellulosic and lipid-based biomass crops. This is largely due to the relatively low costs and reliability of production. At present, production of non-food plant-derived oils for biofuel production in the U.S. is minimal. A research team from the Commonwealth Scientific and Industrial Research Organization (CSIRO), an independent Australian federal government research institution, has developed an efficient transgenic system to engineer oil production in tobacco leaves. This novel system is comprised of multiple transgenes that direct the endogenous metabolic flux of oil precursors towards triacylglycerol (TAG) production. Additional genes were …

Higher levels of Fusarium damaged kernels and the toxin deoxynivalenol (DON) were observed in the warmed treatment compared to the control, and plant development was …


Stress, Cognitive Distortions, Engagement In Self-Care, And Burnout In Psychology Graduate Students, Lauren Matturro Jan 2019

Stress, Cognitive Distortions, Engagement In Self-Care, And Burnout In Psychology Graduate Students, Lauren Matturro

PCOM Psychology Dissertations

Psychology graduate students are tasked with finding a balance between academic responsibilities, clinical training, home life, time constraints, and financial concerns. These competing demands lead to stress, which is well documented in medical students with similar workloads, but understudied in psychology graduate students. Previous studies indicate that perceived stress can be linked to prevalence of an individual’s cognitive distortions. Additionally, stress within the human service fields often leads to burnout. Self-care is widely recognized as a preventative effort against developing burnout. However, as students have limited time, they may find engaging in self-care activities to be difficult. The purpose of …

A Case For United States Overhaul Of Its Current Biotechnology Regulation Scheme Through The Implementation Of Biotechnology-Specific Legislation To Clarify Existing Uncertainties Seen In The Collective Framework, Jordan Emmert Jan 2019

A Case For United States Overhaul Of Its Current Biotechnology Regulation Scheme Through The Implementation Of Biotechnology-Specific Legislation To Clarify Existing Uncertainties Seen In The Collective Framework, Jordan Emmert

Cardozo International & Comparative Law Review

The U.S. biotechnology regulatory framework, established by the 1986 Coordinated Framework and its 1992 Update, is outdated and insufficient to address modern biotechnology products, particularly genetically modified organisms (GMOs). While efforts such as the Obama Administration’s 2015 Memorandum and the 2016 Update aimed to modernize the system, they failed to resolve jurisdictional ambiguities and regulatory gaps, leading to inconsistent agency enforcement and public distrust. The note argues that updating the statutory framework is essential to align U.S. regulations with international norms, ensure public safety, and maintain global competitiveness.


Weak Warning Signals Can Persist In The Absence Of Gene Flow, J. P. Lawrence, Bibiana Rojas, Antoine Fouquet, Johanna Mappes, Annelise Blanchette, Ralph A. Saporito, Renan Janke Bosque, Elodie A. Courtois, Brice Noonan Jan 2019

Weak Warning Signals Can Persist In The Absence Of Gene Flow, J. P. Lawrence, Bibiana Rojas, Antoine Fouquet, Johanna Mappes, Annelise Blanchette, Ralph A. Saporito, Renan Janke Bosque, Elodie A. Courtois, Brice Noonan

Faculty and Student Publications

Aposematic organisms couple conspicuous warning signals with a secondary defense to deter predators from attacking. Novel signals of aposematic prey are expected to be selected against due to positive frequency-dependent selection. How, then, can novel phenotypes persist after they arise, and why do so many aposematic species exhibit intrapopulation signal variability? Using a polytypic poison frog (Dendrobates tinctorius), we explored the forces of selection on variable aposematic signals using 2 phenotypically distinct (white, yellow) populations. Contrary to expectations, local phenotype was not always better protected compared to novel phenotypes in either population; in the white population, the novel phenotype evoked …

Faculty and Student Publications

© 2018 The Linnean Society of London The non-monophyly of both the genus Myersiohyla and the Boana punctata group has been recovered in a number of published phylogenetic analyses. In this paper we report on the analysis of sequences of Boana liliae, a species originally assigned to the B. punctata group, in a dataset of Cophomantini that recovered novel phylogenetic relationships for this hylid tribe. Our results reveal Myersiohyla to be paraphyletic with respect to B. liliae. Support for the placement of Myersiohyla kanaima is poor, but this taxon is recovered as the sister taxon of the other Cophomantini genera …

Shared Value Over Fair Use: Technology, Added Value, And The Reinvention Of Copyright, Amy Whitaker Jan 2019

Shared Value Over Fair Use: Technology, Added Value, And The Reinvention Of Copyright, Amy Whitaker

Cardozo Arts & Entertainment Law Journal

The protection of fair use in the arts has become an inflexible binary. Either artist Shepard Fairey has permission to use the Associated Press photograph of Barack Obama to create the Hope Poster, or he has stolen the image in violation of copyright. This legal framework is rigid, inaccurate, and creatively unsafe. Yet it is the interpretation, not the doctrine itself, that needs shifting. The copyright statute already includes an overlooked "value" test that can more accurately reflect collaboration and sampling in the digital age. And yet instead, some scholars have responded to digital copying by suggesting we throw out …


Changes In The Children's Television Marketplace, The Children's Television Act, And The First Amendment, Joel Timmer Jan 2019

Changes In The Children's Television Marketplace, The Children's Television Act, And The First Amendment, Joel Timmer

Cardozo Arts & Entertainment Law Journal

Since the passage of the Children's Television Act of 1990, broadcast television stations have been required to provide educational programming for children as a condition for license renewal. Since 1996, broadcasters can fulfill this obligation by providing three hours of such programming according to the Federal Communications Commission's (FCC) guidelines. These requirements were later extended to broadcasters' multicast channels. With more children's programming available today than ever before from a wide variety of sources, and with changes in the ways children consume programming, the FCC has proposed to revise its rules to reflect these changes. This Article considers the constitutionality …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Considerable effort has been directed toward controlling Johne’s disease (JD), a chronic granulomatous intestinal inflammatory disease caused by Mycobacterium avium subsp. paratuberculosis (MAP) in cattle and other ruminants. However, progress in controlling the spread of MAP infection has been impeded by the lack of reliable diagnostic tests that can identify animals early in the infection process and help break the transmission chain. To identify reliable antigens for early diagnosis of MAP infection, we constructed a MAP protein array with 868 purified recombinant MAP proteins, and screened a total of 180 well-characterized serum samples from cows assigned to 4 groups based …

Quantification Of Macrophages And Mycobacterium Avium Subsp. Paratuberculosis In Bovine Intestinal Tissue During Different Stages Of Johne’S Disease, Caitlin J. Jenvey, Jesse M. Hostetter, Adrienne L. Shircliff, John Bannantine, Judith R. Stabel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Johne’s disease is an enteric disease caused by the intracellular pathogen Mycobacterium avium subsp. paratuberculosis (MAP). Upon ingestion of MAP, it is translocated across the intestinal epithelium and may be killed by intestinal macrophages, or depending on the bacterial burden and immunological status of the animal, MAP may thwart innate defense mechanisms and persist within the macrophage. This study aimed to determine the numbers of macrophages and MAP present in bovine midileal tissue during different stages of infection. Immunofluorescent (IF) labeling was performed on frozen bovine midileal intestinal tissue collected from 28 Holstein dairy cows. The number of macrophages in …

Wolves: A Primer For Ranchers, John Williams, Douglas E. Johnson, Patrick E. Clark, Larry L. Larson, Tyanne J. Roland

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Ranch management has become more complex since wolves were reintroduced into Idaho and Wyoming in 1996. In wolf areas, livestock have experienced increased death loss and greater stress. Increased livestock aggressiveness has been observed, especially toward working dogs, making handling livestock more difficult. Additionally ranchers have reported a loss of body condition, lower conception rates, increased time and expense for management. Our study was designed to investigate the effect of wolf presence on cattle behavior, landscape use patterns, and resource selection by comparing high wolf density areas against low wolf density areas. This study also generated baseline information on cattle …


Weaving A Localized Context Of Use: What It Means For Instructional Design, John Baaki, Monica W. Tracey Jan 2019

Weaving A Localized Context Of Use: What It Means For Instructional Design, John Baaki, Monica W. Tracey

STEMPS Faculty Publications

The purpose of our manuscript is to probe what a localized context of use means for instructional design practice and of environments in which learning occurs. A localized context of use emphasizes specific moments of use where context is scaled back to what is needed in a situation or moment. We begin by looking at the evolution of context of design. We review context in instructional design since Tessmer and Richey's (1997) contextual approach to instruction. We then present our localized context of use through the actions of a learner and a designer, provide applications for practice, and implications for …
