Achilles Tendon Rupture in Collegiate Athletes
No full textThe Achilles tendon is a thick band of fibrous connective tissue originating from the distal end of the gastroc-soleus complex and inserting on the posterior portion of the calcaneus. This tendon serves to connect the gastrocnemius and soleus muscle to the foot, allowing force production and transmission from the lower extremities through the feet. The Achilles tendon is one of the largest and strongest tendons in the body due to the extreme force demands required of the structure. Activities such as running and jumping are much more efficient in humans due to the presence of the Achilles tendon. As humans age, the tendon begins to deteriorate, sometimes resulting in a rupture. This significant orthopedic injury is generally the result of explosive force, exceeding the tensile strength of the tissue in recreational male athletes aged 40-55. However, a recent occurrence of ruptures at Hope College suggests a possible change in the typical age and profile of a patient with a ruptured Achilles tendon. This case study serves to examine one such case and explore the changes in age, gender, and athletic profile of Achilles tendon ruptures
Characterization of the Pseudocapacitive Nature of Surface Bound Prussian Blue Analogues
No full textWith the increased use of intermittent renewable energy sources, more efficient methods of energy storage must be explored. Electrochemical capacitors provide a larger volumetric charge density than physical capacitors while maintaining fast charge and discharge rates. Prussian Blue analogues (nickel and cobalt hexacyanoferrate) are ideal pseudocapacitors for frequent charge and discharge cycles since the crystalline structure does not physically change during switching, causing less stress on the film. This project examines the charge transfer and diffusion coefficients for nickel and nickel-cobalt thin films modified with potassium hexacyanoferrate. The films were examined using a scanning electron microscope, an atomic force microscope and an electrochemical workstation to determine their composition, topography and psuedocapacitive nature. Preliminary data suggest that nickel-cobalt films have a larger quantity of charge and have a lower diffusion coefficient per charge than nickel films
Dealloying NiCo and NiCoCu Alloy Thin Films Using Linear Sweep Voltammetry
No full textWhen electrodeposited into thin films, metals have unique and well-known electrochemical potentials at which they will be removed from the film. Theoretically, these potential differences can be utilized to re-oxidize only certain metals in an alloy, thus altering the film’s structure and composition. This dealloying process is understood relatively poorly in the case of nickel-cobalt and nickel-cobalt-copper thin films. Here we discuss these films’ response to linear sweep voltammetry as a means of electrochemical dealloying. A three-electrode electrochemical cell was used for both deposition and dealloying. To perform linear sweep voltammetry on a sample, it was immersed in a sodium sulfate solution in the electrochemical cell and a steadily increasing potential was placed between the working and reference electrodes. For each of four different metal ratios, films were dealloyed to various potentials in order to gain insight into the evolution of the film over the course of the linear sweep. Capacitance, topography, and composition were examined for each sample before and after linear sweep voltammetry was performed. For nickel-cobalt films with high percentages of nickel, dealloying resulted in almost no change in composition, but did result in an increased capacitance, with greater increases occurring at higher linear sweep potentials. Dealloying also resulted in the appearance of large (100-1000 nm) pores on the surface of the film. For nickel-cobalt-copper films with high percentages of nickel, copper was almost completely removed from the film at linear sweep potentials greater than 500 mV. Preliminary data suggested that the linear sweep first removes larger copper-rich dendrites from the film’s surface before creating numerous nano-pores, resulting in a net increase in area
Effect of Different Tempo Music on Balance Performance in Fatigued College Students
No full textMusic has been shown to have positive effects on posture, while also decreasing heart rate and respiratory rates. Additionally, it can act as a distraction from pain and fatigue. Previous research has shown that music may increase balance; however it is not yet clear if the tempo of the music influences the degree to which balance is improved. Therefore, the purpose of this study was to determine the effect of listening to two different music tempos on fatigued individuals’ postural sway during unilateral quiet standing. Twelve recreationally active colleged-aged participants underwent a fatiguing task on a cycle ergometer and two balance tests: one before and one after the fatiguing exercise. Balance was analyzed using a force plate. Participants stood with their right foot centered on the force plate with eyes open for 20 seconds and then with their eyes closed for 10 seconds. During the post fatigue balance test, slow tempo music, fast tempo music, or no music (control) was played. It was hypothesized that slow tempo music would have a calming effect on the autonomic nervous system and allow participants to focus, resulting in improved balance performance, and less postural sway. Significant results would offer music as a technique for improving balance in competitive and personal activities, such as dance, gymnastics and yoga. Additionally, more research could be conducted to implement music as a form of rehabilitation. This study is ongoing, and results will be available during the poster celebration
Examining the Overrepresentation of African Americans in the Foster Care System from a Policy Perspective
No full textIn 2013, African Americans made up 14% of the 0-17 population and 24% of the 0-17 population in foster care in the United States (2013 KIDS COUNT Data Book). Statistics on the obstacles facing youth when they exit—through aging out—the foster care system are frightening as these young adults are at a much greater risk for being diagnosed with a mental health disorder, experiencing homelessness, living in poverty and dropping out of high school. The issue of the overrepresentation of African American children in foster care has experienced increased legislative attention in the last ten years specifically; however, it will continue to remain an important policy issue until it is eradicated. Potential policy solutions include: increasing the size and scope of available social services, expanding the emphasis on cultural competency training, and reorganizing funding to allow for stipends in guardianship placements. This project seeks to explain policy change under this topic from the viewpoints of Institutional Theory and Elite Theory
Excess Post-Exercise Oxygen Consumption
No full textAnaerobic metabolism primarily meets the body’s energy demands at the onset of exercise until aerobic metabolism is able to sufficiently supply ATP. The portion of energy that aerobic metabolism is unable to supply is termed oxygen deficit. Sixteen collegiate track runners (age 18-23 years) participated in a study to determine the effect of traditional middle distance and long distance training on the respective training groups’ oxygen deficit values. A short-term (4 minute) treadmill test was used to determine the differences in oxygen deficit and cardio-respiratory values of two training groups. Changes in oxygen deficit over an 8-week aerobic training were measured via area-under-the-curve calculations and comparisons were made between the middle distance and distance training groups’ physiological responses
Exploring Alternative High Schools: Does Emotional Intelligence Matter?
No full textIn this multi-year, qualitative study, we explored local alternative high schools to see how adding the component, Emotional Intelligence (EI) to a school’s curriculum affected the learning environment for students who attended these schools. In this phase of the project, we worked with the students and teachers at Pioneer Tech High School, an alternative high school operated by Hamilton Schools. We created an observation protocol based on Daniel Goleman’s 2005 book: Emotional Intelligence: Why It Can Matter More Than IQ, and on an extensive literature review on successful alternative high schools. We observed classes during the school day at Pioneer Tech to determine when and to what extent the school implemented the variables of a successful alternative school and EI. The data sources analyzed for this presentation included the observation protocol, observation field notes, interviews with students and school staff, and focus group conversations. Initial findings will inform the next phase of the project, the design and implementation of an EI framework developed collaboratively with the research team and the staff at Pioneer Tech
Flourishing in the Wake of a Disaster: Investigating the Effects of Disaster-Related Stimuli on Meaning, Well-Being, and Religion
No full textDisasters can present a context for investigating how disruptive life events affect individuals’ meaning in life and religion and spirituality. Disasters are understudied, and it is unclear how they affect meaning in life. The purpose of the current study is to establish that disasters are a threat to meaning and to determine how disaster primes affect meaning in life, religion, and spiritual well-being. The 100 participants in this study were introductory psychology students at a small Midwestern liberal arts college. Participants were randomly assigned to one of three conditions: (1) reading and providing a written summary of a disaster situation while imagining themselves in the situation (disaster prime condition), (2) reading and providing a written summary of an essay about the meaninglessness of life (meaning threat condition), and (3) reading and providing a written summary of an essay about computers (control condition). After reading the prime and writing the summary, participants completed surveys regarding their experienced emotion, meaning in life, religious variables, personality differences, virtuous behavior, and well-being. We predicted that the disaster prime will operate like the meaning threat prime and differ from the control condition across all of the dependent variables. Results revealed that individuals in the disaster prime scenario reaffirmed their meaning in life. This suggests that disasters are a threat to meaning and can elicit responses to regain a sense of meaning. Implications of this include discovering how people overcome challenges, such as disasters, in order to grow and to flourish
