A Tale Of Two Antennules: The Performance Of Crab Odor-Capture Organs In Air And Water, Lindsay D. Waldrop, Laura A. Miller, Shilpa Khatri

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Odour capture is an important part of olfaction, where dissolved chemical cues (odours) are brought into contact with chemosensory structures. Antennule flicking by marine crabs is an example of discrete odour capture (sniffing) where an array of chemosensory hairs is waved through the water to create a flow–no flow pattern based on a narrow range of speeds, diameters of and spacings between hairs. Changing the speed of movement and spacing of hairs at this scale to manipulate flow represents a complicated fluid dynamics problem. In this study, we use numerical simulation of the advection and diffusion of a chemical gradient …

The Artists Journey- Strolling The Edges Of The Universe, Mary P. Williams

Theses and Dissertations

Space exploration has always fascinated me, and so has the idea ( so far fictional) that humankind may someday encounter extraterrestrial life. My series of paintings and prints are a visual expression of the awe and wonder I feel as I follow our species’s unending drive to expand the boundaries of its known world.

But the unknown is not just out there in interstellar space. And there are other lifeforms to encounter right here on our own planet. Another series of my paintings documents Earth’s flora. Our ties to the microorganisms, animals, and plants on our planet, and the life …

Lipan Apache Tribe Of Texas: Ethnic And Racial Identity, Ashley S. Leal

Theses and Dissertations

The findings presented in this study are based on a series of semi-structured interviews, focused on racial, ethnic and cultural identity, with 20 registered members of the Lipan Apache Tribe of Texas. Analysis of the interviews show that while members are spread across the country the basic cultural identity still remains the same: they are all cultural and tribal ambassadors to future generations and the world around them. Results indicate that interviewed members share the same aspirations of becoming federally recognized by the United States government, not for any type of benefits but to be seen as real Indians through …

Antonio's Lament: "Mightily Abused" In Twelfth Night, Quintin Walton

Perpetua: The Journal of Undergraduate Research at UAH

The play Twelfth Night depicts the fluid nature of sexuality, although it ends with the standard trope undergirding romantic comedy: inevitable het-erosexual unions. Additionally, Twelfth Night upsets stereotypical constructions of masculinity and sexual desire by provocatively introducing Antonio (a heroic sea captain) who saves Sebastian (a beautiful young man) from watery destruction; more-over, they form a homoerotic domestic partnership that lasts three blissful months—a substantial time-line in Shakespearean comedy. The ongoing critical conversations on this topic are limited to a discussion of bisexuality (Pequigney), a consideration of the im-plications of homoerotic partnership (Thomas), and an observation of the inherent cruelty …

Inflationary Gravitational Waves And B-Mode Polarization Of The Cosmic Microwave Background, Kylie Todd Heflin

Perpetua: The Journal of Undergraduate Research at UAH

This paper is an attempt to introduce the concept of gravitational waves, interpret the results of BICEP2 and Planck, analyze the methods employed by both missions, and evaluate the implications of the existence of inflationary gravitational waves (IGWs). BICEP2/Keck Array are experiments aimed at meas-uring the polarization of the cosmic microwave back-ground (CMB), as well as providing speculation re-garding the origin of B-Mode polarization of the CMB. In June 2014, BICEP2 reported the detection of such polarization but acknowledged uncertainty regarding its origin due to the possibility of gravita-tional lensing caused by cosmic dust. BICEP2’s de-tection used a CMB polarimeter …

Prisoner Resistance In The Auschwitz And Buchenwald Concentration Camps, Regina Coffey

Honors Theses

A great deal has been written about the Holocaust and about resistance organizations that formed in the concentration camps. Much of this literature, however, tends to focus on the contributions of a particular group of prisoners rather than on the many groups that came together to form these organizations. The purpose of this study, therefore, is to examine the resistance organizations in Auschwitz and Buchenwald concentration camps using firsthand accounts and to come to a conclusion on how cooperation between different groups of prisoners affected the overall effectiveness of these resistance organizations.

Expression Of Glycine-Rich Proteins Found In Salivary Glands Of The Lone Star Tick (Amblyomma Americanum) Using A Mammalian Cell Line, Annabelle Clark

Honors Theses

Ticks play an important ecological role as well as a growing role in human health and veterinary care. Ticks are hosts to a plethora of microbial pathogens that can be transferred during feeding to cause tick-borne diseases in humans and many animals. Ticks may in large part owe the success of the transfer of these pathogens between hosts to their complex saliva. The saliva secreted upon a tick’s attachment to a host serves the following, among other, functions: anti-hemostasis of the blood pool, preventing an inflammatory response at the bite site, and serving as a natural anti-microbial substance. An important …

A Study Evaluating If Targeted Training For Startle Effect Can Improve Pilot Reactions In Handling Unexpected Situations In A Flight Simulator, Michael Gillen

Theses and Dissertations

Recent airline accidents point to a crew’s failure to make correct and timely decisions following a sudden and unusual event that startled the crew. This study sought to determine if targeted training could augment decision making during a startle event. Following a startle event cognitive function is impaired for a short duration of time (30-90 seconds). In aviation, critical decisions are often required to be made during this brief, but critical, time frame.

A total of 40 volunteer crews (80 individual pilots) were solicited from a global U.S. passenger airline. Crews were briefed that they would fly a profile in …

The Effects Of Time Of Day And Circadian Rhythm On Performance During Variable Levels Of Cognitive Workload, Kathryn A. Feltman

Theses and Dissertations

The present study examined the effects of time of day of testing on a simulated aviation task. The tasks required the participants to engage in multitasking while electroencephalogram (EEG) data was collected to objectively measure participants’ workload. Task demands were altered throughout the testing period to expose participants to both high and low workload conditions. Additionally, individual differences in circadian rhythm were explored by assessing participants’ circadian typology. No significant differences in performance were found resulting from time of day differences. However, performance and EEG differences were found based on phase of testing and workload manipulations. Subjective workload measures were …

Regional Airline Pilot Commute: How Commuting By Air Affects Pilots' Satisfaction With Life, Andrew David Kleinfehn

Theses and Dissertations

At a time of increased use and competitiveness amongst U.S. regional airlines, and the growing pilot shortage, regional air carriers and pilots alike lack proper understanding how pilot commutes by airplane affect satisfaction with life. There are numerous studies on how commuting by vehicle, bicycle, mass transit system, or walking (traditional commute) to and from work affects one’s satisfaction with life. There are no identified studies which investigate regional airline pilots’ commute by airplane and its affect on satisfaction with life. The purpose of this study was to gain knowledge on regional airline pilot commutes, how commuting affects regional pilots’ …

Statistical Techniques To Model And Optimize Performance Of Scientific, Numerically Intensive Workloads, Steena Dominica Steven Monteiro

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Projecting performance of applications and hardware is important to several market segments—hardware designers, software developers, supercomputing centers, and end users. Hardware designers estimate performance of current applications on future systems when designing new hardware. Software developers make performance estimates to evaluate performance of their code on different architectures and input datasets. Supercomputing centers try to optimize the process of matching computing resources to computing needs. End users requesting time on supercomputers must provide estimates of their application’s run time, and incorrect estimates can lead to wasted supercomputing resources and time. However, application performance is challenging to predict because it is …

Oocyte Quality: Molecular Constituents Altered In The Oocyte Due To Various Environmental Factors, Lindsay Cox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimated 1.6 million American couples struggle with infertility. Some causes for poor fertility can be clearly defined but in many instances, subfertility is unexplained. Poor oocyte quality is now considered to be a main contributing factor for many causes of infertility. Good oocyte quality is crucial for many processes including embryo development and maintaining pregnancy. There is a possibility that any alterations to the oocyte can have long lasting effects on embryo development and the health of the offspring. The oocyte is very sensitive to any perturbations to its surrounding environment. Transcripts for apoptosis inhibitors and epigenetic modifiers were …

Simple Soil Quality Tests And Organic Management Practices For Orchards In The Intermountain West, Esther Oline Thomsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil health is often overlooked as a long-term management strategy as growers face an increasing number of short-term management challenges in the Intermountain West. The costs of inputs are rising and water resources are becoming more limited. Soil with poor health typically requires more amendments and fertlizers to meet crop needs. Soil health tests can help reveal management practices that reduce soil health, as well as those that improve soil health. Practices known to improve soil health are reduced to no tillage, cover crop use- especially legumes, and addition of mulch and other organic materials. Soil health testing is not …

The Effects Of Rootstock, Scion, Grafting Method And Plant Growth Regulators On Flexural Strength And Hydraulic Resistance Of Apple, Stuart W. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The apple rootstock ‘Geneva^® 41’ (‘G.41’), is desirable for its resistance to fire blight, Erwinia amylovora, while producing high yields. However, ‘G.41’ and other Geneva^® selections tend to form weak graft unions in the nursery that are susceptible to breaking in the wind, at harvest, or during shipment. In order to understand and remedy this graft union weakness, six scions (‘Fuji’, ‘Gala’, ‘Honeycrisp’, ‘McIntosh’, ‘Pink Lady’, and ‘Scilate’) by seven rootstocks (‘G.41’, ‘G.935’, ‘G.214’, ‘G.11’, ‘M.9-NIC 29’, ‘B.9’ and ‘EMLA 26’), by two grafting methods (chip bud and saddle graft) in a factorial design were tested for graft …

The Effect Of Prosody On Preschool Children’S Emotional, Cognitive, And Behavioral-Eye And Behavioral-Body Engagement During Story Time, Trevor Rowe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many children have insufficient early literacy experiences and fail to obtain proficient emergent literacy before they enter kindergarten. Reading to young children has been positively linked to improving their emergent literacy. Numerous factors influence how engaged children are while being read to including the adult’s prosody, receptive vocabulary, and the home literacy environment. Using a quantitative quasi-experimental design, this study sought to understand the association among prosody, child engagement (emotional, cognitive, behavioral-eye, and behavioral-body), receptive vocabulary, and the home literacy environment. The sample included 76 3- to 5-year-old children from local child care centers and their parents. To understand the …

School of Health Professions

BACKGROUND: Around 17% of people eligible for UK cardiac rehabilitation programmes following an acute coronary syndrome report moderate or severe depressive symptoms. While maximising psychological health is a core goal of cardiac rehabilitation, psychological care can be fragmented and patchy. This study tests the feasibility and acceptability of embedding enhanced psychological care, composed of two management strategies of proven effectiveness in other settings (nurse-led mental health care coordination and behavioural activation), within the cardiac rehabilitation care pathway. METHODS/DESIGN: This study tests the uncertainties associated with a large-scale evaluation by conducting an external pilot trial with a nested qualitative study. We …

The Use Of Scenarios In Legal Education To Develop Futures Thinking And Sustainability Competencies, Michelle Mei Ling Lim, Andrew Allan

Research Collection Yong Pung How School Of Law

Achieving sustainability requires a populace equipped to deal with complex, interacting and ever-changing realities as well as uncertain futures. There is however a significant lack of focus on developing sustainability competencies within legal and governance education. Legal education plays a key role in shaping sustainable futures. Long-term sustainability relies on lawyers, judges and policy-makers being able to make optimal decisions in the present when faced with significant uncertainty about the future. This paper discusses how the combination of problem-based learning (PBL) and scenario-based pedagogical approaches can provide an authentic contextualised learning environment to empower law students to deal with the …

Social Media And Political Communication In The 2014 Elections To The European Parliament, Paul Nulty, Yannis Theocharis, Sebastian Adrian Popa, Olivier Parnet, Kenneth Benoit

Research Collection School of Social Sciences

Social media play an increasingly important part in the communication strategies of political campaigns by reflecting information about the policy preferences and opinions of political actors and their public followers. In addition, the content of the messages provides rich information about the political issues and the framing of those issues during elections, such as whether contested issues concern Europe or rather extend pre-existing national debates. In this study, we survey the European landscape of social media using tweets originating from and referring to political actors during the 2014 European Parliament election campaign. We describe the language and national distribution of …

“Grand challenges” are formulations of global problems that can be plausibly addressed through coordinated and collaborative effort. In this Special Research Forum, we showcase management research that examines societal problems that individuals, organizations, communities, and nations face around the world. We develop a framework to guide future research to provide systematic empirical evidence on the formulation, articulation, and implementation of grand challenges. We highlight several factors that likely enhance or suppress the attainment of collective goals, and identify representative research questions for future empirical work. In so doing, we aspire to encourage management scholars to engage in tackling broader societal …

Processing Incomplete K Nearest Neighbor Search, Xiaoye Miao, Yunjun Gao, Gang Chen, Baihua Zheng, Huiyong Cui

Research Collection School Of Computing and Information Systems

Given a setS of multidimensional objects and a query object q, a k nearest neighbor (kNN) query finds from S the k closest objects to q. This query is a fundamental problem in database, data mining, and information retrieval research. It plays an important role in a wide spectrum of real applications such as image recognition and location-based services. However, due to the failure of data transmission devices, improper storage, and accidental loss, incomplete data exist widely in those applications, where some dimensional values of data items are missing. In this paper, we systematically study incomplete k nearest neighbor (IkNN) …
