  1. Development and Assessment of an Oscillatory Motion Tutorial

    Young, Nicholas
    Our research over the previous two semesters has indicated that introductory physics students are not able to consistently determine the angular frequency, period, or frequency from graphical representations and do not have a firm grasp on these concepts. Since the harmonic oscillator is a fundamental model in many physical and biological systems, it is critical that students understand the concepts and relationships that underlie the model. In order to help students develop these skills, we created a tutorial that could be completed in a 40-minute group work session. The tutorial guided students to work in small groups to complete tasks...

  2. Schooling individuals discover a novel food source via social learning faster than non-schooling individuals

    Troyer, Emily
    Novel information, such as the location of a new food source, can be transmitted throughout a group via social learning, as opposed to direct sampling of the environment. When learning is asocial, individuals will encounter a novel food source on their own, with no guidance from others. However, in a social learning environment, individuals will learn of a novel food source by directly observing others. Schooling or flocking behavior, which is often seen in fish and birds, also allows for social learning to occur, due to the close proximity individuals have with one another in their group. The purpose of...

  3. An Econometric Study Evaluating the Role of "Office of Patient Experience" on Experiential Outcomes in U.S. Hospitals

    Jha, Anuvrat
    Since the inception of the Patient Protection and Affordable Care Act (PPACA), there has been a drastic change in the delivery of healthcare. Payment reform was one of the key attributes of the PPACA, shifting the reimbursement model from fee-for-service to value based purchasing (VBP). In the VBP model, payments are bundled and reimbursement is based on a VBP score. The VBP score is comprised of 70% process management (Quality & Safety) and 30% patient experience during their hospital stay. Patient experience is measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) score. These measures are quantifiable...

  4. Grain Size Analysis of Submarine Landslides in the Nankai Trough

    Rohan, Tyler
    A two part investigation of a mass transport deposit (MTD) in the Nankai Trough, offshore Japan was conducted to learn more about the dynamic behavior of submarine landslides. Hydrometer analysis of 50 sediment samples from the Integrated Ocean Drilling Program (IODP) Expedition 333, Site C0018 was completed with the objective to determine the grain size distribution within a prominent mass transport deposit (MTD-B). Core samples were collected from 90.17 to 191.17 meters below the seafloor (mbsf) with approximately 1 sample per 1 meter collected inside MTD-B. MTD-B was also cored at Site C0021, IODP Expedition 338 providing a valuable opportunity...

  5. Gender Differences in Venture Capital Funding on ABC’s Shark Tank

    Hunt, Tyler
    ABC Network’s reality television show “Shark Tank” gives entrepreneurs the opportunity to pitch their ideas to a panel of investors for the chance to receive funding. Each season more than 35,000 entrepreneurs apply to be on the show. Whether they receive an offer for funding or not, they still stand to gain the free advertising that comes with appearing on a show with more than seven million average viewers per episode. Although there are abundant resources for knowledge on Shark Tank, women in venture capital, and behavioral gender differences, sources are lacking on gender differences in venture capital funding on...

  6. Effect of diet and bacterial clearance on energy expenditure in the cockroach Periplaneta americana

    Ondrejech, Andy
    Gut microbiota presumably constitutes an important source of essential nutrients in insects. To study the effect of microbiota on the nutritional state of animals, it is common to use antibiotics and observe the effects of bacterial clearance. However, there might be a confounding effect between the physiological effects of nutritional stress and those produced by the antibiotic itself. In this study, we investigated the effect of clearance of gut microbes in the American Cockroach (P. americana). We fed cockroaches with either a high quality diet (dog food) or a low quality diet (dog food, 30%, mixed with cellulose, 70%). Within...

  7. Facebook Happiness

    Lu, Kailun
    As the world’s largest social networking site, Facebook has reached 1.59 billion monthly active users around the globe as of December 2015. People access Facebook because they want to connect with their friends and family. People want to find happiness on Facebook, but do they? The purpose of this research is to measure how Facebook users’ emotions change after looking at Facebook, and the role played by different types of Facebook posts and its social comparison. The research was conducted online using 128 college students ranging from the ages of 16 to 41. Since Facebook users were exposed to many...

  8. Scaling Social Enterprse in Developed and Developing Countries

    Rumburg, Kelsey
    Social enterprise is an emerging field focusing on the use of entrepreneurship and earned income to run a business with a social focus and mission. While the idea is certainly not new, academic analysis, coursework, and degree programs are a recent development in this interdisciplinary subject. Prominent research in the field currently focuses on the key traits of a social entrepreneur, case studies for specific countries, and the sectors in which social enterprise develops and thrives. However, very little research has been done on social enterprise as it spans different economies. As social enterprises seek to solve major societal issues,...

  9. Registered Nurses’ Perception of Top of License Practice Activities

    Hlahol, Melanie
    The rapid changes in health care in tandem with the increasing complexity of inpatient care requires that nursing leaders and healthcare administrators think carefully about how best to maximize the education and skill set of the Registered Nurse (RN). Given the shortage of healthcare providers, gaps in care often fall to the RN, and thus RNs have to take on responsibilities that fall below their scope of practice. RNs therefore are unable to perform other activities that they see as value added, such as spending more time with the patient and providing important patient education. The purpose of this study...

  10. A systematic review of the link between childhood obesity and adult cancers

    Schumacher, Makaila A.
    Over the past three decades, Americans’ rates of overweight and obese have steadily increased. It has been suggested that childhood obesity may increase the risk of cancer in adulthood. Much literature has focused on specific cancers or the mechanisms of obesity and its sequelae. Consequently, a systematic review is needed to more fully examine the relationship between childhood obesity and adult-related cancers. This review examined the evidence of the obesity and cancer relationship. A secondary aim was to determine the adult cancers most associated with childhood obesity. Pubmed and Cinahl were searched during the fall of 2014. Criteria for inclusion...

  11. Ed Watson: Teaching Big Data to K-12 Students

    Muhammad, Stephanie; Kelley, Jaimie; Stewart, Christopher
    Online data-intensive (OLDI) services such as Google Now, Apple Siri, and IBM Watson provide answers to questions formed using natural language. Although these services are widely used, K-12 students are rarely introduced to concepts relating to them. A lack of early exposure to these concepts force the chances of students developing academic or career interests relating to OLDI concepts to rely on the exposure they may receive during their pursuit of higher education. The Ed Watson educational package is a proposed solution to counteract the lack of exposure at the K-12 level. Ed Watson introduces K-12 students to natural language...

  12. Characterization of Loading Environment on Human Ribs during Respiration

    Stemmer, Katherine
    The human thoracic cavity holds vital organs, such as the heart and lungs. The rib cage provides protection to these organs, and as a result is susceptible to injuries. One important determinant in the susceptibility of ribs, and bone in general, to fracture is the accumulation of microfractures. These microfractures occur in ribs due to cyclic loading and stress during normal ventilation. Since microfractures accumulate in regions of bone that experience high local strains, it is important to measure the strain patterns ribs experience during the regular loading environment of breathing. The strain mode of the cutaneous cortex and pleural...

  13. Trends in Reasons for Restatements

    Brackman, Kyle
    In 2014, more than 500 companies or over 3% of all public companies filed a Form 8-K Item 4.02 disclosure indicating that a previously issued financial statement should not be relied upon due to a material error. These material errors mislead investors, creditors, and other stakeholders. Therefore, such a company is subsequently required to issue corrected financial statements through a Form 10-K/A disclosure. By understanding the underlying errors that drive companies to restate, accountants can take actions to minimize the quantity of restatements. Previous research has examined the relationship between the passage of time and the number of restatements. This...

  14. Argentine Tango Practice as a Balance Intervention for Cancer Survivors

    Lamantia, Marie
    Cancer survivors have reported that problems in balance and walking are a leading cause of distress and discomfort post-cancer. This critical loss of balance function is attributed to deconditioning and peripheral neuropathy resulting from chemotherapy treatments or lymphedema. Our study evaluates feasibility of the use of Argentine Tango to improve balance among cancer survivors, focusing on survivors who are deconditioned or nerve damaged (e.g. Chemotherapy Induced Peripheral Neuropathy). Our primary aim is to determine the feasibility of conducting a 10-week, dance-based balance intervention given concerns regarding retention and compliance among participants who are receiving concurrent care in oncology and rehabilitation....

  15. The Impact of Sudden Changes in Title I Funding on Ohio School Districts

    Conrad, Cameron
    Through the 1965 Elementary and Secondary Education Act (ESEA), the federal government established Title I funding to target resources for districts serving low-income students. The reauthorization of ESEA in 2001 expanded the program’s funding significantly, making Title I the largest federal education finance program aimed at improving the achievement of low-income students, yet the impact of this funding on disadvantaged students is still heavily debated. Determining the causal impact of Title I funding on district spending and student learning is difficult because the poverty counts at the center of the funding formula are also correlated with these outcomes. This study...

  16. Vulnerability of the National Electric Grid to Renewable Power Consumption

    Elsbernd, Kenneth
    Trends over the past 25 years suggest a decline in fossil fuel consumption per capita and an increase in per capita consumption of renewable energies. Consumption per capita of energy generated from fossil fuels, as a percentage of the total per capita consumption, declined from 92.3% to 89.3%, while per capita consumption of renewables increased from 7.7% to 12.0%. Should these trends persist, the utilities sector could be in danger of decreased profits, which could lead to cost cutting measures and ultimately a lessening of maintenance for the national electric grid in the distant future. A multiple linear regression model...

  17. Role of aminoacyl-tRNA synthetases and viral RNA structure in the initiation of reverse transcription

    Hatterschide, Joshua; Cantara, William; Wu, Weixin; Musier-Forsyth, Karin
    Human T-cell leukemia virus type-1 (HTLV-1) is a human retrovirus that causes adult T-cell leukemia/lymphoma (ATL)—a rapidly degenerative non-Hodgkin’s lymphoma that affects roughly 5% of infected individuals. According to the most recent estimates, 5-10 million people are infected with HTLV-1 worldwide, yet there are currently no successful therapies for ATL. This underlines the importance of further research into the retroviral lifecycle. Before the genome of a retrovirus can be integrated into the host cell genome, it must undergo reverse transcription (RT) from RNA to DNA. In order for RT to initiate, a tRNA primer must anneal to the primer binding...

  18. Isolation and Genomic Analysis of Bacteria that drive biogeochemical cycling in Prairie Pothole Lake sediments

    Lynes, Mackenzie; Johnston, Michael; Dalcin-Martins, Paula
    The prairie pothole region of North America, covering approximately 750,000 km2, contains millions of small lakes that are important systems for regional carbon and sulfur cycling. Prairie pothole lake (PPL) sediment pore waters contain some of the highest dissolved organic carbon concentrations ever measured in freshwater ecosystems. Sediment and pore water samples from the PPLs of North Dakota were used to anaerobically enrich for sulfate reducing bacteria (SRB) and fermentative microorganisms. Given the high sulfate concentrations characteristic of PPL pore waters, we suspect that SRB play an important role in coupled carbon and sulfur cycling, while fermenters degrade more complex...

  19. Nonanoic Acid Exhibits Inconsistency Between Bulk and Surface pKa

    Lach, Evan A.; Wellen, Bethany A.
    Organic molecules at the ocean surface influence the climate through their reactions as coatings on sea spray aerosols, although many complex processes have not yet been fully described. By further characterizing molecules at this surface, climate effects through aerosol processes could be deduced. One common organic at the ocean surface is nonanoic acid (NA), which may be formed via the oxidation of oleic acid by gas phase species such as ozone. The pKa for an acid is characteristic and gives insight into its reactivity, but its value at the air-water interface is not necessarily the same as in bulk solution...

  20. Interaction of Retronasal and Orthonasal Perception of Unfamiliar Flavors

    Moeller, Lindsay
    Aroma compounds can be perceived through orthonasal (through the nose—smelling) or retronasal (through the mouth—flavor) mechanisms. These signals are processed by the same receptors and by the same sections of the brain, but are thought to elicit different perceptions, hedonic responses and behaviors. In this experiment, sensory evaluation of unfamiliar flavors by retronasal (flavor) and orthonasal (smell) perception were studied. The unfamiliar flavors used were Yuzu, Carambola, Hibiscus, and Momo. A matching test wherein panelists were given a reference sample containing one of the aroma compounds and told to identify that sample amongst the four unknowns was performed for three...
