Method For Instant Saccharomyces Cerevisiae Kill Of Samples, Melissa Kohner, Sara Dick

Symposium on Research and Creative Expression (SORCE)

It is essential when studying the circadian rhythm in cells to be able to effectively stop them in time. In this experiment, we tested what would be the most successful killing agent on Saccharomyces cerevisiae. Six different agents were tested at different concentrations and amounts. After the S. cerevisiae was added to the test tube containing the agent, it was streaked on a plate after 5 and 10 minutes. The plates were incubated and then checked for growth. Ethanol was the most efficient killing agent. After an effective killing agent is determined, it can be used in further experiments measuring …

The Effects Of Chronic Lower Back Pain On Muscle Activation And Range Of Motion, Gina Lange, Laura Richards

Symposium on Research and Creative Expression (SORCE)

The purpose of this study was twofold: first, to examine the muscle activation of lower back muscles during various trunk positions in persons with and without chronic lower back pain (CLBP); second, to examine the relationship between perceived levels of pain and muscle activation and range of motion. Five subjects with CLBP and five subjects without CLBP volunteered to participate. Using an Electromyogram (EMG) the muscle activity of the ten subjects were recorded during three different trunk positions—standing neutrally, standing with 30 degrees flexion, and standing with maximum hyperextension of the trunk. The subject’s perceived pain in each position was …

Effect Of Emotional Cues On Memory Recall And Response Time, Rachel Rahn

Symposium on Research and Creative Expression (SORCE)

Combining electroencephalography, the recording of the brain's electrical activity, with other psychological research techniques allows the link between memory and emotion to be investigated. This study, which is currently in the pilot phase, investigates the effect of emotions on performance in a memory test. Subjects are shown written memory cues with or without accompanying photos of strong facially-expressed emotions and later prompted to recall the written cues. By monitoring brain activity and recall success rate, emotion's effect on memory in this context can be determined, including what brain regions are stimulated by the emotion-memory link and the improvement or impairment …

The Effects Of Tarp Wrapping On Blow Fly Oviposition During Decomposition Of Pigs, Natasha Lobosky, Jordan Stein

Symposium on Research and Creative Expression (SORCE)

The effects of blow fly oviposition on 12 young, recently deceased pigs were studied during a one month period in the fall semester of 2012. This project follows similar techniques that Dr. Bugajski used during her research project at Purdue. Using tarp-wrapped bodies as the sole variable, bare pigs were held as the control. The data that were collected included the presence or absence of larvae or adult flies, daily temperatures, samples of both larvae and adult flies, and the start and end of maggot migration. The samples of larvae and adult flies were later identified in the lab and …

Butchered Butcher, Melissa Kohner

Symposium on Research and Creative Expression (SORCE)

In this paper, I explore the murder of Christian H. Schindeldecker and how the police were able to find and prosecute the murderer, Edward Gottschalk. I recount the actions of Chief of Police John O'Connor and his men as they follow the clues and with a little luck connect the dots of the mysterious murder. Thirteen days after Schindeldecker was murdered, Gottschalk was arraigned for murder. Solving the murder of Christian Schindeldecker was one of the best cases of detective work ever done in Minnesota. Following the firsthand account of Chief Deputy Sheriff Frank Robert Jr., court papers, and contemporary …

Optimizing The Allocation Of Vaccines In The Presence Of Multiple Strains Of The Influenza Virus, Abby Kenyon, Ana Eveler, Tayler Grashel, Jessica Richardson

Symposium on Research and Creative Expression (SORCE)

During the annual flu season, multiple strains of the influenza virus are often present within a population. It is a significant challenge for health care administrators to determine the most effective allocation of two different vaccines to combat the various strains when treating the public. We employ a mathematical model, a system of differential equations, to find a strategy for vaccinating a population in order to minimize the number of infected individuals. We consider various strengths of transmission of the disease, availability of vaccine doses, vaccination rates, and other model parameters. This research may lead to more effective health care …

Diversity And Abundance Of Aquatic Macroinvertebrates Associated With Different Benthic Substrates In The East Branch Of The Little Calumet River, Halina Hopkins, Ali Olson

Symposium on Research and Creative Expression (SORCE)

As part of an ongoing study of the effect of removing logjams to open the East Branch of the Little Calumet River for recreational purposes, we worked with park staff at the Indiana Dunes National Lakeshore on a study of the abundance and diversity of aquatic macroinvertebrates. We used a quantitative sampling technique to obtain samples of macroinvertebrates from five substrates in reaches of the river above and below four focal logjams. Diversity as measured by the Shannon-Weiner index varied with river substrate (sand=1.467, root wad=1.854, wood=1.64). Sand had the lowest average number of macroinvertebrates (92, as compared to 191 …

A Gis Analysis Of Environmental Justice In Lake And Porter Counties, Halina Hopkins

Symposium on Research and Creative Expression (SORCE)

Starting with the publication in 1987 of the United Church of Christ Racial Justice Commission Report "Toxic Wastes and Race in the United States," environmental justice research addresses the geospatial relation between environmental hazards and the social characteristics of the communities hosting toxic sites. Geographic Information Systems (GIS) allows environmental justice researchers to consider questions involving public policy, health effects, risk analysis, and more nuanced considerations of race, income, and injustice. This project is an analysis of environmental justice in two counties in northwest Indiana: Lake County, which contains the city of Gary; and Porter County, an adjacent county with …

Facilitating Positive Reactions To Psychological Labels, Stephanie Kuipers

Symposium on Research and Creative Expression (SORCE)

Receiving a psychological label is often a life-changing experience. Some people feel relieved and hopeful upon discovering a name for their problem, while others become scared and depressed about the implications of receiving such a label (Proudfoot et al., 2009). This study attempts to identify factors that may affect whether a client has a positive or negative reaction to psychological labeling. Specifically, three factors were examined: use of language, client personality, and type of diagnosis. Each participant was randomly assigned to read one of four short narratives in which they imagined themselves in the depicted situation. All narratives portrayed someone …

Do Classroom Teaching Methods Incorporate All Types Of Learning Styles?, Samuel Zucker

Symposium on Research and Creative Expression (SORCE)

An individual’s learning style is a natural pattern of processing or acquiring knowledge. Three types of learning styles that were studied are visual, auditory, and kinesthetic (tactile). An individual’s ability to acquire knowledge depends upon the style of instruction received by the teacher. The purpose of this project was to examine whether the teaching methods used in a high school biology classroom take into account different types of student learning styles. Student teaching in a biology class has given the author the opportunity to study the learning needs of the students. The participants were given a questionnaire during class asking …

The Usefulness Of Scientific Field Trips: What Are High School Students’ Attitudes Towards Them?, Aaron Wayne Willis

Symposium on Research and Creative Expression (SORCE)

The purpose of this study is to analyze students’ attitudes toward scientific field trips. This study will evaluate whether students have a positive, negative, or neutral attitude toward going on these scientific field trips. Also, using this questionnaire, the data collected from four dimensions – the learning aspect, the social aspect, the adventure aspect, and the environmental aspect – will help measure the students’ attitude toward scientific field trips. This study will encompass a questionnaire being passed out to multiple high school students from various grades and learning levels (regular, honors, AP, and IB). I will be unable to test …

Four Virtues: Interventions For Goodness' Sake, Caroline Lavelock

Theses and Dissertations

Empirical interest in promoting virtues has dramatically increased over the last decade. The present study will focus primarily on the warmth-based virtues of forgiveness and humility, and the conscientiousness-based virtues of patience and self-control. I introduced participants (N = 135) to a workbook intended to promote one of these four virtues, or to promote general positivity for participants in a workbook control condition. I hypothesized that virtue workbooks would produce higher levels of the target virtue, more so than in both a non-action control condition (n = 33) and in a control condition that completes a workbook that promotes general …

The Biomechanics Of Spear Throwing: An Analysis Of The Effects Of Anatomical Variation On Throwing Performance, With Implications For The Fossil Record, Julia Marie Maki

All Theses and Dissertations (ETDs)

Accurate, high velocity throwing is a skill unique to humans among living species. It likely provided an adaptive advantage for our hominin ancestors, either in the context of hunting, or protection from predators. Thus, understanding how variation in body form and anatomy influences throwing ability may provide insight into the evolution of human morphology. Research has been done on various forms of ball and javelin throwing, yet the biomechanics of spear throwing were completely unknown. Moreover, it has been suggested that early modern humans had lesser effective mechanical advantage: EMA, the ratio of moment arm to load arm) than Neandertals, …

Growing Up Tamarin: Morphology, Reproduction, And Population Demography Of Sympatric Free-Ranging Saguinus Fuscicollis And S. Imperator, Mrinalini Watsa

All Theses and Dissertations (ETDs)

The Callitrichidae are family of small New World primates with a suite of distinctive morphological and behavioral adaptations that set them apart from other primates. Of primary interest is their reproductive system that includes compulsive twinning: ≥80% of births) and cooperative care of offspring by individuals other than biological parents: termed alloparenting). Further, hematopoietic tissues in callitrichids display signals of both self and sibling DNA, due to an exchange of stem cells early in gestation that renders twin callitrichids as cellular mosaics of each other. This phenomenon is known as genetic chimerism, which increases genetic relatedness between individuals and is …

The Physiological And Morphological Responses Of The Bladder Urothelium To Differential Injury, Kristina Marie Stemler

All Theses and Dissertations (ETDs)

The bladder is the site of various diseases such as urinary tract infections: UTI), bladder pain syndrome/interstitial cystitis: BPS/IC), and bladder cancer. UTIs and BPS/IC primarily afflict women and treatment costs over $5 billion and almost $200 million respectively in 2006. Quality of life in BPS/IC patients is low; comparable to individuals with end stage renal disease. Recent research has identified a role for the epithelial lining of the bladder, which is usually targeted by these afflictions, in potentially contributing to enhancing pain. The bladder epithelium also showcases a rapid ability to regenerate after injury.

The Explanatory Indispensability Of Mathematics: Why Structure Is 'What There Is', Nils Richards

Theses

Inference to the best explanation (IBE) is the principle of inference according to which, when faced with a set of competing hypotheses, where each hypothesis is empirically adequate for explaining the phenomena, we should infer the truth of the hypothesis that best explains the phenomena. When our theories correctly display this principle, we call them our ‘best’. In this paper, I examine the explanatory role of mathematics in our best scientific theories. In particular, I will elucidate the enormous utility of mathematical structures. I argue from a reformed indispensability argument that mathematical structures are explanatorily indispensable to our best scientific …

Notions Of Spirits As Agents Of Mental Illness Among The Akan Of Ghana: A Cultural-Psychological Exploration, Annabella Opare-Henaku

Theses and Dissertations

The study explores lay conceptualizations of mental illness among the Akans of Ghana as influenced by their cultural worldview. Akan, the largest ethnic group in Ghana, is noted for the use of supernatural attributions for various health-related issues. The supernatural attributions are based on Akan ontological belief that the universe is unitary such that there is no clear distinction between physical and spiritual occurrences. This worldview guides Akans in how they deal with a wide range of issues including their mental health. Clinicians and other mental health professionals who rely solely on biomedical approaches to mental health fail to meet …

Identification Of Genes Involved In Pseudomonas Aeruginosa Biofilm-Specific Resistance To Antibiotics, Li Zhang, Meredith Fritsch, Lisa Hammond, Ryan Landreville, Cristina Slatculescu, Antonio Colavita, Thien-Fah Mah

Dartmouth Scholarship

Pseudomonas aeruginosa is a key opportunistic pathogen characterized by its biofilm formation ability and high-level multiple antibiotic resistance. By screening a library of random transposon insertion mutants with an increased biofilm-specifc antibiotic suscepti bility, we previously ident ified 3 genes or operons of P. aeruginosa UCBPP-PA14 ( ndvB , PA1875–1877 and tssC1 ) that do not affect biofilm formation but are involved in biofilm-specific antibiotic resistance. In this study, we demonstrate that PA0756–0757 (encoding a putative two-component regulatory system), PA2070 and PA5033 (encoding hypothetical proteins of unknown function) display increased expression in biofilm cells and also have a role in …
