Air Temperature And Diet Are Not Associated With Oxygen Consumption Rate In Banded Crickets, Gryllodes Sigillatus, Nicole Bailey, Connor Oakes, Rachel Sleeth, Mallorie Smith Apr 2023

Air Temperature And Diet Are Not Associated With Oxygen Consumption Rate In Banded Crickets, Gryllodes Sigillatus, Nicole Bailey, Connor Oakes, Rachel Sleeth, Mallorie Smith

Butler Journal of Undergraduate Research

All living organisms acclimate to their environments, with ectothermic species particularly susceptible to environmental change, specifically temperature. Ectothermic insects like crickets directly alter their physiological processes depending on the environment in which they live. Temperature is vital in regulating processes such as metabolism, respiration, and reproduction, among other things. What remains unclear is how a change in the environment, specifically extreme temperature change and dietary alterations, affects physiological processes. In this study, we performed experiments on ectothermic banded crickets to examine the effects of temperature change and the interaction of temperature and diet on oxygen consumption. For both experiments, we …

Effects Of Anthropogenic Noise On Body Mass In Gryllodes Sigillatus, Jessica L. Venturi, Joyce Zheng Apr 2023

Effects Of Anthropogenic Noise On Body Mass In Gryllodes Sigillatus, Jessica L. Venturi, Joyce Zheng

Butler Journal of Undergraduate Research

Insects use vibrational structures to produce and sense airborne sounds in intraspecific communication. These signals are important in courtship as well as defensive behavior against predators. For example, insects can detect the presence of nearby predators using vibrations. With an increase in anthropogenic activity, processing these signals and the constant threat they represent may increase stress on insects, subsequently affecting their behavior and physiology. Our experiment was designed to determine whether anthropogenic noise, possibly perceived as a stressor, will decrease the body mass of banded crickets, Gryllodes sigillatus. We predicted that the anthropogenic noise would stress the crickets, leading to …

Truth, Not Accuracy: Native American Fiction Vs. White Settler Colonialism, Charles Democker Apr 2023

Truth, Not Accuracy: Native American Fiction Vs. White Settler Colonialism, Charles Democker

Butler Journal of Undergraduate Research

For centuries, depictions of Native American culture have largely been constructed by White authors and have thus reflected white settler colonialist ideology. This paper suggests that one way to counter this point of view when studying Native American history is to turn to fiction, specifically fiction written by Indigenous authors. Taking as an example Ojibwe author Louise Erdrich’s Plague of Doves, a novel based on the real-life massacre of a frontier family in the late nineteenth century, this paper argues that the creative fiction of Indigenous authors can counter the biased, incomplete, and often incorrect official histories of White–Native interactions. …

Almost 30 Years Later: Anti-Femicide Activism In Mexico From 1993 To 2022, Kathryn Webb Apr 2023

Almost 30 Years Later: Anti-Femicide Activism In Mexico From 1993 To 2022, Kathryn Webb

Butler Journal of Undergraduate Research

What factors have influenced the strategies of the anti-femicide social movement, and what has this movement accomplished after continuously advocating for almost 30 years? Analyzing news articles, scholarly journals, books on social movements, and Twitter accounts, I argue that the inaction of the government was a root cause of the movement’s change in strategies, from peaceful petitions to highly visible vandalism, and that institutional barriers prevent progress on this issue even in the current day. I demonstrate that transnational activism through international institutions such as the United Nations had a limited impact on effecting domestic change but that using social …

The Effects Of Covid-19-Induced Stress, Anxiety, And Depression On The Eating Behavior Of College Women, Natalie Simpson Apr 2023

The Effects Of Covid-19-Induced Stress, Anxiety, And Depression On The Eating Behavior Of College Women, Natalie Simpson

Butler Journal of Undergraduate Research

Increases in the prevalence of disordered eating patterns have been linked to distress and poor mental well-being. Additionally, COVID-19 has been linked to both depressive and anxious symptomatology, along with increased feelings of distress (Fitzpatrick et al., 2020). Because disordered eating is particularly prevalent among college-age women, this study sought to determine how depression, anxiety, and stress affect eating behaviors of college women in the context of the COVID-19 pandemic. One hundred seventy-nine women, aged 18–24, at Butler University gave informed consent before completing a questionnaire pertaining to their demographics, their stress surrounding COVID, and their weight change since March …

An Evaluation Of Women’S Social Status In Colonial Hong Kong With A Feminist Lens - Case Studies, Heng Du Apr 2023

An Evaluation Of Women’S Social Status In Colonial Hong Kong With A Feminist Lens - Case Studies, Heng Du

Butler Journal of Undergraduate Research

Even though Hong Kong remained under British control from 1842 to 1997, denizens were not modernized in a way comparable to that of the British. To the contrary, while governing Hong Kong, British colonizers allowed continued reference to ancient Chinese customs in the area. Such policy diminished women’s chances of receiving fair treatment in matters such as property management and divorce. Unlike in Hong Kong, women were legislated to be parallel to men in matrimonial and property inheritance petitions in China, Britain, and colonial Singapore. This study is based on two exemplary cases judged by authorities in colonial Hong Kong. …

Identifying Disinformation In Scholarly Publishing, Natalie M. Mclendon Apr 2023

Identifying Disinformation In Scholarly Publishing, Natalie M. Mclendon

Butler Journal of Undergraduate Research

This paper examines the pro-Confederacy movement’s attempt to distort history through textbook revision to argue in favor of strengthened media literacy as a brace against the effects of disinformation and propaganda. Previous definitions of misinformation and disinformation overlap and are as yet unclear and, therefore, should be further studied. “Lost Cause” mythologists worked diligently to propagate school textbooks which portrayed skewed versions of history that cast Southern Confederates’ cause as noble and honorable while obscuring the real reason for the Civil War. While undergraduate students can rely on the CRAAP and BEAM methods of identifying problematic texts, they should be …

Multiple Endpoints In Randomized Controlled Trials: A Review And An Illustration Of The Global Test, Lindsay Cameron Apr 2023

Multiple Endpoints In Randomized Controlled Trials: A Review And An Illustration Of The Global Test, Lindsay Cameron

Electronic Thesis and Dissertation Repository

A randomized controlled trial is often used to provide high quality evidence regarding treatment interventions. Due to the complex nature of many diseases, trials usually select multiple primary outcomes to capture the efficacy of the interventions. In this thesis, we conducted a literature search to determine the prevalence of the different types of multiple outcomes that have been used in randomized controlled trials. We also reviewed the corresponding statistical methods used to deal with such outcomes. In addition, we described the benefits of using global tests as a statistical method when there are multiple primary outcomes in order to answer …

Topological Data Analysis Of Weight Spaces In Convolutional Neural Networks, Adam Wagenknecht Apr 2023

Topological Data Analysis Of Weight Spaces In Convolutional Neural Networks, Adam Wagenknecht

Dissertations

Convolutional Neural Networks (CNNs) have become one of the most commonly used tools for performing image classification. Unfortunately, as with most machine learning algorithms, CNNs suffer from a lack of interpretability. CNNs are trained by using a training data set and a loss function to tune a set of parameters known as the layer weights. This tuning process is based on the classical method of gradient descent, but it relies on a strong stochastic component, which makes the weight behavior during training difficult to understand. However, since CNNs are governed largely by the weights that make up each of the …

Selective Preservation Of Structural Carbohydrates During Peat Formation, Lauren Bryan, Rachel Shaw, Madison Smith, Erik Schoonover, Trevor Hile, Christian Lundy, Alexis Koehl, Grace Behrens, Madeleine O'Donnell, Mackenzie Dole Apr 2023

Selective Preservation Of Structural Carbohydrates During Peat Formation, Lauren Bryan, Rachel Shaw, Madison Smith, Erik Schoonover, Trevor Hile, Christian Lundy, Alexis Koehl, Grace Behrens, Madeleine O'Donnell, Mackenzie Dole

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

The structural carbohydrate "sphagnan" has been hypothesized to play a role in slowing the degradation of Sphagnum moss, and therefore contribute to carbon sequestration in peatlands. Sphagnan is composed of a galacturonic acid and rhamnose backbone. However, it is currently unclear whether sphagnan persists beyond early-litter degradation and plays a role in the long-term preservation of organic matter in peatlands. In this study, we analyzed hydrolyzable neutral sugars, using rhamnose as a proxy for sphagnan content, and tracked the concentration of rhamnose present within moss before and after a 270-day period of decomposition, as well as the concentration of rhamnose …
