Russian Mathematical Pedagogy In Reasoning Mind, Maia Valcarce

HMC Senior Theses

Reasoning Mind (RM) incorporates aspects of Russian mathematics pedagogy and curricula into its online math program. Our investigation identifies typical attributes of Russian pedagogy discussed in news articles and publications by Russian education experts, then determines how these attributes arise in RM. Analysis of RM's implementation of the characteristics reveals more successful inclusion of curricular attributes than classroom strategies. Thus, we outline classroom techniques that could be assimilated into RM to provide a more Russian learning experience along with students' exposure to Russian-style curricula.

Religiosity, Knowledge Of Evolution, And Political Ideology As Predictors Of Attitudes Towards The Evolution V. Creationism Controversy, Nikolaus Philip Schuetz

Theses (6 month embargo)

Since Darwin On the Origin of Species over 150 years ago, evolution via natural selection has gained essentially unilateral support among scientists, with 97% of scientists agree that life evolved over time, while a mere 12% to 29% of the general public accepts evolution via natural selection. About three-quarters of the public support teaching creationism in public school science classes--a violation of the First Amendment--and a recent survey shows that just 28% of high school biology teachers advocating for evolution in their classroom, as per the national guidelines.

The present study aims to investigate and clarify certain relationships that lead …

How Adopting Stereotypical Roles May Impact Sexual Risk Behavior Among Young African American College Women, Essie Hall

Dissertations (2 year embargo)

Sexually transmitted infection (STI) prevention issues for women, particularly women of color, are multifaceted and far-reaching. Cultural dynamics unique to black women, such as attitudes, values and beliefs are often not considered. The proposed study assesses culturally specific factors that may inform sexual decision-making for African American college students in an urban setting. The study proposes to analyze how knowledge, the adoption of stereotypical attitudes (four specifically: Mammy, Sapphire, Jezebel, and Superwoman) and religiosity (attendance) may influence the sexual choices of young adult African American college women.

One hundred and ten African American women attending a predominantly Black and urban …

Flatterland: The Play, Kym Louie

HMC Senior Theses

This script is an adaptation of the popular science novel Flatterland: Like Flatland, Only More So by Ian Stewart. It brings new life to mathematical ideas and topics. By bringing math to the stage, concepts are presented in a more friendly and accessible manner. This play is intended to generate new interest in and expose new topics to an audience of nonmathematicians.

Coherent Pattern Prediction In Swarms Of Delay-Coupled Agents, Luis Mier-Y-Teran-Romero, Eric Forgoston, Ira B. Schwartz

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

We consider a general swarm model of self-propelling agents interacting through a pairwise potential in the presence of noise and communication time delay. Previous work has shown that a communication time delay in the swarm induces a pattern bifurcation that depends on the size of the coupling amplitude. We extend these results by completely unfolding the bifurcation structure of the mean field approximation. Our analysis reveals a direct correspondence between the different dynamical behaviors found in different regions of the coupling-time delay plane with the different classes of simulated coherent swarm patterns. We derive the spatiotemporal scales of the swarm …

The Dynamics Of Location: Influence Of Predation By Chaoborus Larvae On Rotifer Diel Vertical Migration Patterns, Kristina P. Riemer

Lawrence University Honors Projects

The locations of freshwater organisms in lakes are determined by the convergence of many competing factors. While predation pressure is one of these, also important are areas of food concentration and the physical and chemical constraints of a system. Diel vertical migration is a behavior exhibited by freshwater organisms in many taxa that is the result of balancing these factors. Diel vertical migration consists of movement by these organisms throughout the water column in accordance with a 24 hour cycle. This oscillation is generally driven by the competing factors of predation pressure and food acquisition, and is modified by physical …

Host Pathogen Interactions: Is Arabidopsis Thaliana Remembered By Its Nemesis Pseudomonas Syringae?, Daniel Z. Kreiser

Lawrence University Honors Projects

Plants contain innate immune systems that deter pathogen infection. Pattern recognition receptors bind microbe-associated molecular patterns (MAMPs), triggering immunity. MAMPs are proteins exclusive to pathogens that are typically indispensable for their survival. For this reason, MAMPs cannot be mutated or removed without causing pathogen death. However, this does not necessitate constitutive expression of MAMPs. In this study, the MAMP response of Arabidopsis thaliana was utilized to determine differential detection of MAMPs expressed by Pseudomonas syringe pv. tomato DC3000 when pretreated with A. thaliana. Results demonstrated that more MAMPs are detected when P. syringae had previously encountered A. thaliana, …

Alterations In Brain Connectivity After Spinal Cord Injury Using Functional Mri, Yamin Ahmed Noor

Theses

Every year, approximately 50 people per million of inhabitants are inflicted by Spinal Cord Injury (SCI). The long-term impairment of the SCI patients has led researchers to investigate different rehabilitation and treatment efforts that require careful observations to be made on reliable markers. Presently, a number of neuropsychological assessments are used for SCI rehabilitation and research purposes. However, there is a need for the discovery of sensitive biomarkers that can be used to characterize SCI. Altered functional connectivity in the brain has been observed in a number of neurological patient populations. Hence, it was hypothesized that such alterations in brain …

The Effects Of Theophylline On The In Vitro Respiratory Response To Hypoxia, Ke Geng

Theses

The isolated transverse brainstem slice preparation of neonatal mice is employed to investigate the function of theophylline, a competitive nonselective phophodiesterase inhibitor and adenosine receptor antagonist, on the hypoxic ventilatory response. Brainstem slices are isolated from neonatal mice (4-8 days old) and superfused with artificial cerebrospinal fluid (aCSF), equilibrated with a hyperoxic gas mixture (95% O₂, 5% CO₂) as a control, and anoxic mixture (0% O₂, 5% CO₂, 95% N₂) to create severe hypoxia at the tissue level. Using suction electrodes, extracellular population activities of respiratory neurons is recorded from …

Experimental Evaluation Of Near Infrared Light Penetration Into Neural Tissue, Ujwal Anil Parikh

Theses

Near infrared (NIR) lasers find applications in medicine both for diagnostic and treatment purposes. Penetration depth into the tissue is a critical parameter to be considered in these NIR laser applications. Published data on the optical properties of rodent neural tissue are rare, despite the frequent use of rats as animal models. The aim of this study was to directly measure the light intensity profile inside the rat brain gray matter that is illuminated by an NIR laser beam. The local light intensities were sampled using an optical fiber inserted into the brain. The intensity profile in the axial direction …

Fmri Assessment Of Ischemic Stroke In Humans, Rui Yuan

Theses

Cerebral ischemia, or brain ischemia is a kind of stroke where the blood flow is insufficient to the metabolic demand of brain. The lack of oxygen supply will directly lead to the death of brain tissue. There are two major injury regions: the infarct and penumbra. Mostly, since the infarct regions became dead tissues rapidly after stroke, there is a tiny possibility to rescue them in time. But penumbra parts are different. Tissues there will be viable for hours after ischemia. Hence, both theoretically and practically, it is possible to salvage those cells in the penumbra region. Diffusion weighted image …

Effects Of Low-Dose Drinking Water Arsenic On Mouse Fetal And Postnatal Growth And Development, Courtney D. Kozul-Horvath, Fokko Zandbergen, Brian P. Jackson, Richard I. Enelow, Joshua W. Hamilton

Stumbling Into Change And Overcoming My Creative Fears In The Process: My Cct Experience Identifying And Overcoming Uncertainty And Fear In My Creativity, Lorna J. Riach

Critical and Creative Thinking Capstones Collection

Though I originally enrolled in CCT as a means to prevent me from working too much, I ended up discovering I actually needed to do much more work –toward my creative development, instead of my professional development. While my “head-on” approach had proven effective and successful in my professional development when faced with challenges, it turned out that the same approach would be ineffective toward my attempts at personal change. Fears quickly emerged in my creativity that required my consideration - before I could enjoy any level of success. This synthesis considers the development and manifestation of my fears in …

Simplified Models Of Vector Control Impact Upon Malaria Transmission By Zoophagic Mosquitoes, Samson S. Kiware, Nakul Chitnis, Sarah J. Moore, Gregor J. Devine, Silas Majambere, Stephen Merrill, Gerry F. Killeen

Mathematics, Statistics and Computer Science Faculty Research and Publications

Background

High coverage of personal protection measures that kill mosquitoes dramatically reduce malaria transmission where vector populations depend upon human blood. However, most primary malaria vectors outside of sub-Saharan Africa can be classified as “very zoophagic,” meaning they feed occasionally (

Methods and Findings

We extended a published malaria transmission model to examine the relationship between transmission, control, and the baseline proportion of bloodmeals obtained from humans (human blood index). The lower limit of the human blood index enables derivation of simplified models for zoophagic vectors that (1) Rely on only three field-measurable parameters. (2) Predict immediate and delayed (with …

The Abaya: Fashion, Religion, And Identity In A Globalized World, Elizabeth D. Shimek

Lawrence University Honors Projects

The abaya is a traditional robe worn by women in the Arab Gulf states as both a symbol of national identity and as a part of Islamic veiling customs. Over the last twenty years, partly due to exposure to Western couture fashion, the abaya has changed from a plain, voluminous black robe to a unique signifier of personal taste through variations in fabrics, cuts, colors, and detailing. This study explores both the physical and symbolic changes the abaya (and the industry surrounding it) has undergone, as well as how these changes both reflect and provoke the conflicts in identity residents …

Discovery Of A Novel Antibiotic From A Bacillus Bacterium Cultivated From Its Natural Environment, Patrick J. Mcmonagle

Lawrence University Honors Projects

The current primary method of treating bacterial infections is using antibiotics. However, this continued treatment of these illnesses caused by pathogenic bacteria is causing the rate of evolution of these disease-inducing organisms to increase. Antibiotic resistance is forcing scientists to search for new forms of antibiotics to compete with these new ‘super bugs.’ I pursued the search for novel antibiotics through their natural source – antibiotic-producing microorganisms. As microbes have a direct advantage when producing antibiotics, it is my thought that they will be the best resource to discovering new and effective antibiotics. I conducted an exploratory search for antibiotic-producing …

Otx But Not Mitf Transcription Factors Are Required For Zebrafish Rpe Development, Brandon Lane

Theses and Dissertations

Mitf and Otx transcription factors have been identified as essential to the development of the retinal pigmented epithelium (RPE), but the relationship between these factors and their specific role in the RPE developmental pathway have not been clearly defined. The role of the two Mitf transcription factors (Mitfa and Mitfb) and two Otx transcription factors (Otx1a and Otx2) in zebrafish RPE development was explored in these experiments. The loss of Mitf activity in mitfa, mitfb, or double mitf null mutant fish lines had no effect on RPE pigmentation or development. The loss of Otx2 activity through morpholino knockdown produced a …

Heterogeneity-Aware And Energy-Aware Scheduling And Routing In Wireless Sensor Networks, Mahesh Kumar Vasanthu Somashekar

Theses

A Wireless Sensor Network (WSN) is a group of specialized transducers, called sensor nodes, with a communication infrastructure intended to monitor and record conditions at diverse locations. Since WSN applications are usually deployed in an open environment, the network is exposed to rough weather conditions, such as rain and snow. Another problem that WSN applications need to deal with is the energy constraints of sensor nodes. Both problems adversely affect the lifetime of WSN applications. A lot of research has been conducted to prolong the lifetime of WSN applications considering energy constraints of sensor nodes, but not much research has …
