An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham Jan 2015

An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham

Theses and Dissertations (Comprehensive)

Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at ...

Lkb1 Deficient Non-Small Cell Lung Cancer Cells Are Vulnerable To Energy Stress Induced By Atp Depletion, Chao Yang Dec 2014

Lkb1 Deficient Non-Small Cell Lung Cancer Cells Are Vulnerable To Energy Stress Induced By Atp Depletion, Chao Yang

UT GSBS Dissertations and Theses (Open Access)

Lung cancer is the second most frequent cancer in United States, which represents about 13.5% of new cancer cases every year. It accounts for about 27.2% of all cancer related deaths, which is more than the sum of deaths caused by prancretic, breast and colorectal. On average, only about 16% of lung cancer patients survive beyond 5 years. LKB1 is the third most mutated gene in lung cancer. It has been shown that LKB1 is mutated in at least 15% to 30% of NSCLC. Tumor with LKB1 mutation is associated with poor differentiation, high metastasis and worse response ...

STRUCTURAL INVESTIGATIONS OF LIGAND GATED ION CHANNELS

Swarna Ramaswamy, B.S

Advisor: Vasanthi Jayaraman, Ph.D.

Ion channels form an integral part of membrane proteins. In the nervous system including the central and the peripheral nervous system, ligand gated ion channels form a very important part of intercellular communications. They receive chemical signals and convert them to electrical signal, mainly by allowing ion passage across the cell membrane. Ion passage also translates into downstream signaling events. Faithful translation of these signals and transmittance is crucial for several physiological functions, implying that irregular ion channel function could lead to serious consequences ...


Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak Dec 2014

Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak

Theses, Dissertations, & Student Scholarship: Agricultural Leadership, Education & Communication Department

Carol Dweck’s research on fixed vs. growth mindset has led to many opportunities for educational research. According to Dweck, a person with a fixed mindset believes that his or her qualities related to a certain task are unchangeable while an individual with a growth mindset believes that his or her qualities related to a certain task can be changed and improved (Dweck, 2006). A correlative study was conducted to identify relationships that exist between student mindset and scores from the Nebraska State Accountability Test (NeSA). For this study, students in the 7th, 8th, and 11th grade ...


Testing Gene-Environment Interactions In The Presence Of Measurement Error, Chongzhi Di, Li Hsu, Charles Kooperberg, Alex Reiner, Ross Prentice Nov 2014

Testing Gene-Environment Interactions In The Presence Of Measurement Error, Chongzhi Di, Li Hsu, Charles Kooperberg, Alex Reiner, Ross Prentice

UW Biostatistics Working Paper Series

Complex diseases result from an interplay between genetic and environmental risk factors, and it is of great interest to study the gene-environment interaction (GxE) to understand the etiology of complex diseases. Recent developments in genetics field allows one to study GxE systematically. However, one difficulty with GxE arises from the fact that environmental exposures are often measured with error. In this paper, we focus on testing GxE when the environmental exposure E is subject to measurement error. Surprisingly, contrast to the well-established results that the naive test ignoring measurement error is valid in testing the main effects, we find that ...


University Professors’ Perceptions About The Impact Of Integrating Google Applications On Students’ Communication And Collaboration Skills, Jacqueline L. Cahill Nov 2014

University Professors’ Perceptions About The Impact Of Integrating Google Applications On Students’ Communication And Collaboration Skills, Jacqueline L. Cahill

Journal of Research Initiatives

A qualitative research study was conducted and data were collected by interviewing university professors on their perceptions about the impact of integrating Google Apps, as a means of classroom instructional delivery, on students’ communication and collaboration skills. The participants consisted of eight university professors from a major university, who integrate, or had previously integrated at least two Google Apps Education Edition collaborative tools into their instructional strategies. The result of this study has the potential to benefit universities that are debating on whether utilizing teaching collaborative technology skills, as an instruction tool, would engage students and enhance their communication skills ...


The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris Nov 2014

The Reduction Of Metabolic Cost While Using Handrail Support During Inclined Treadmill Walking Is Dependent On The Handrail-Use Instruction, Cory Hofmann, Connor Dougherty, Hagop Abkarian, Michele Fox, Paul Juris

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 339-345, 2014. Inclined treadmill walking is a commonly performed activity to increase cardiovascular health. Handrail support on a treadmill provides an individual the opportunity to change their posture with respect to the walking surface. Differences in metabolic cost during inclined walking due to postural changes with handrail use are unknown. To test the hypothesis that metabolic cost will differ depending on how handrail support is used, respiratory gas analysis was performed during inclined walking in 13 healthy subjects. Energy expenditure was quantified while each subject walked in four conditions: 5% incline unsupported, 10 ...

Grocery Store Botany, Laura K. Thompson Dr Nov 2014

Grocery Store Botany, Laura K. Thompson Dr

Biology Publications

The vast majority of the plants we consume in our diets are Angiosperms, the most common plants on Earth today. Angiosperms are the plants we encounter most frequently not only in the landscape, but also in the grocery store. In this laboratory, we use grocery store vegetables to examine how Angiosperms are constructed. The study of body form is called morphology, a term coined by the German poet Goethe. As we see in this laboratory, Angiosperms can have diverse morphology. Even among the relatively few domesticated plants we use for food, we find a wide range of forms in the ...

Anthropogenic Noise Alters Bat Activity Levels And Echolocation Calls, Jessie P. Bunkley, Christopher J.W. Mcclure, Nathan J. Kleist, Clinton D. Francis, Jesse R. Barber Nov 2014

Anthropogenic Noise Alters Bat Activity Levels And Echolocation Calls, Jessie P. Bunkley, Christopher J.W. Mcclure, Nathan J. Kleist, Clinton D. Francis, Jesse R. Barber

Biology Faculty Publications and Presentations

Negative impacts from anthropogenic noise are well documented for many wildlife taxa. Investigations of the effects of noise on bats however, have not been conducted outside of the laboratory. Bats that hunt arthropods rely on auditory information to forage. Part of this acoustic information can fall within the spectrum of anthropogenic noise, which can potentially interfere with signal reception and processing. Compressor stations associated with natural gas extraction produce broadband noise 24 hours a day, 365 days a year. With over half a million producing gas wells in the U.S. this infrastructure is a major source of noise pollution ...


Harmonic Language Arts: Music Inclusion In The Secondary English Language Arts Classroom, Julieanne Sthay Nov 2014

Harmonic Language Arts: Music Inclusion In The Secondary English Language Arts Classroom, Julieanne Sthay

CrissCross

Students are required to take four years of high school English, and the mandatory nature of English coupled with a scripted curriculum negatively impact student interest and motivation. English teachers who incorporate music into their academic teaching are finding music can improve student engagement, motivation, and learning (Goering & Burenheide, 2010). In this qualitative self study of student teaching, I explored questions including whether the addition of music is worthwhile in the English classroom, how it can be done, and what the benefits and drawbacks of doing so are. Based upon field notes, lesson plans, student feedback and research, I found ...


Experiencing The Ineffable, Joseph O'Brien Nov 2014

Experiencing The Ineffable, Joseph O'Brien

CrissCross

I can recall the first time I learned to take a fish off the hook after catching it. My grandfather and I were fishing in a river near my home in Connecticut, the sun shone off the yellow of a pumpkinseed sunfish's belly. After removing it from the hook, I put it in a five-gallon pail of water. Despite the clarity of the things I do recall, there are those elements of this memory that remain wholly inaccessible to me. I cannot remember whether it was late spring or early autumn, what color my rod was, or if there ...


Come On Down: Investigating An Informational Strategy To Debias The Anchoring Heuristic, Melissa A. Fuesting Nov 2014

Come On Down: Investigating An Informational Strategy To Debias The Anchoring Heuristic, Melissa A. Fuesting

CrissCross

When individuals estimate the price of goods or services, irrelevant factors may affect the estimates. For example, irrelevant numbers in individuals’ environments can cause participants to “anchor” to them as a starting point price estimates, such that estimates tend toward the anchor (Tversky & Kahneman, 1974; Chapman & Johnson, 1994). In fact, anchored individuals may pay up to three times as much for a product and buy 32% more products (Ariely, Loewenstein, & Prelec, 2003; Wansink, Kent, & Hoch, 1998). Because anchoring affects purchases large and small, this study investigates how to debias, or reduce the negative effects of, the anchoring heuristic. Debiasing strategies are not easily implemented outside the lab where anchoring has the largest real world effects (Strack & Mussweiler, 1997; Chapman & Johnson, 1994; George, Duffy, & Ahuja, 2000).We investigated an easily implemented informational debiasing strategy that would offer little disruption to an individual’s daily routine and investigated whether it could reduce the negative effects of the anchoring heuristic. The strategy had no effect on anchoring, but further investigation with a larger sample size and higher ...


Carving The Perfect Citizen: The Adventures Of Soviet Pinocchio In Text And On Screen, Rachel Branson Nov 2014

Carving The Perfect Citizen: The Adventures Of Soviet Pinocchio In Text And On Screen, Rachel Branson

CrissCross

In 1936, Alexei Tolstoy’s The Golden Key, or The Adventures of Buratino was published, heralding the use of children’s literature and fairy tale structure as an ideological and transformative tool for children in the Soviet Union. The Adventures of Buratino, framed by Alexei Tolstoy’s alleged recreation from memory of Carlo Collodi’sThe Adventures of Pinocchio (1883), was a Soviet fairy tale, portraying Buratino as a hero for his fellow puppets in helping to free them from the corrupt and oppressive power of Karabas Barabas, the owner of the puppet theater. While Barabas serves as an embodiment ...


The Sustained Impact Of An Engaging Diversity Program On College Seniors’ Color-Blind Racial Attitudes, Josefina Banales Nov 2014

The Sustained Impact Of An Engaging Diversity Program On College Seniors’ Color-Blind Racial Attitudes, Josefina Banales

CrissCross

This study utilizes a mixed-methods (quantitative and qualitative) approach to evaluate the long-term impact of Illinois Wesleyan University’s Engaging Diversity Program on white students’ color-blind racial attitudes. Survey data reveals that white students who participated in the program not only endorse fewer color-blind racial attitudes than they did immediately after completing the program, but that they also have a more critical awareness of race than the control sample of non-Engaging Diversity students. Individual interviews with Engaging Diversity participants also reveal a link between these students’ learned racial consciousness and their involvement as social justice leaders and advocates on campus ...


Transforming The Farm Bill: The Local Food Movement And Political Change, Daniel Kenny Nov 2014

Transforming The Farm Bill: The Local Food Movement And Political Change, Daniel Kenny

CrissCross

This study uses the political opportunity structure to measure the success of the local food movement in America. Drawing from the Political Process theory of social movements, I analyze the ability of the local food movement to leverage its transformative capacity into political gain, most notably through the Farm Bill. The current agricultural regime consists of a directed political opportunity structure and political setting, and I find that although the local food movement has made some gains in food and farm policy, the agricultural political landscape continues to be dominated by the interests of industrial agriculture.

Lactate Threshold Comparison In Anaerobic Vs. Aerobic Athletes And Untrained Subjects, Matt Green, Jared Hornsby, Robert Pritchett, Kelley Pritchett

International Journal of Exercise Science

International Journal of Exercise Science 7(4) : 329-338, 2014. This study compared VO2 max, lactate threshold (LT) and VO2 at LT (VO2LT) among aerobic athletes (ARA) (n=10), anaerobic athletes (ANA) (n=9) and untrained participants (UTS) (n=7). From a treadmill test to exhaustion, VO2 max and LT (4 mmol·L-1 blood lactate concentration) were assessed. Analysis of variance showed VO2 max (ml·kg-1·min-1) was significantly greater for ARA (67.6 ± 9.4) than ANA (53.4 ± 6.4) and UTS (44.9 + 6.9), with ANA significantly greater than ...


The Development Of A Valid And Reliable Biogeochemistry Concept Inventory, Chris Mead Nov 2014

The Development Of A Valid And Reliable Biogeochemistry Concept Inventory, Chris Mead

DBER Speaker Series

Concept inventories are a commonly used tool to measure conceptual understanding. To date, concept inventories have been published for geology, chemistry, and biology, but no instrument has been designed to measure conceptual understanding at the intersection of those fields. To fill that gap, we constructed a 32‐item biogeochemistry concept inventory (BGC‐CI). Item response theory analysis, using the Rasch model, shows the BGC‐CI is a reliable and valid tool to measure the biogeochemistry knowledge of science majors. Because biogeochemistry is an interdisciplinary field, we were concerned about the unidimensionality of the instrument. However, our analysis showed the BGC ...

Two Distinct Microbial Communities Revealed In The Sponge Cinachyrella, Marie L. Cuvelier, Emily Blake, Rebecca Mulheron, Peter J. Mccarthy, Patricia Blackwelder, Rebecca Vega-Thurber, Jose V. Lopez

Oceanography Faculty Articles

Marine sponges are vital components of benthic and coral reef ecosystems, providing shelter and nutrition for many organisms. In addition, sponges act as an essential carbon and nutrient link between the pelagic and benthic environment by filtering large quantities of seawater. Many sponge species harbor a diverse microbial community (including Archaea, Bacteria and Eukaryotes), which can constitute up to 50% of the sponge biomass. Sponges of the genus Cinachyrella are common in Caribbean and Floridian reefs and their archaeal and bacterial microbiomes were explored here using 16S rRNA gene tag pyrosequencing. Cinachyrella specimens and seawater samples were collected from the ...
