Host selection and behavioral competition in the parasitic vine, Dodder (Cuscuta gronovii)
No full textThe parasitic weed, Dodder (Cuscuta gronovii.), is a holo-parasitic vine that does not perform photosynthesis, yet it invades a number of potential host species. The mechanisms responsible for ensuring tight adhesion to the wide variety of host surfaces have yet to be identified. It is understood that Cuscuta gronovii must attach to a host within 10-15 days of sprouting to survive. This research study aims to investigate host selection preferences of Cuscuta gronovii seedlings when presented with plants, both preferred hosts and non-hosts, that have been subjected to prior Cuscuta parasitism and plants that have not. The goals from this analysis, are to bring a greater understanding to the competition mechanisms behind Cuscuta parasitism host selection and how the presence of other previously established individuals influences those
Muon Detection with Weather
No full textI present the results of a project to monitor cosmic-ray muons. Muons are an elementary particle that result from atmospheric reactions of cosmic radiation from sources around the earth, such as the sun. This radiation reaches earth and interacts with the atmosphere to produce a shower of muon particles. Various factors affect the detection and flux rate of muons, such as altitude, solar activity, air pressure, and the angle of the detector. Using historical weather data, we are looking to see if meteorological factors such as pressure produce a noticeable effect on the rate of detection of muons. Additionally, we are creating a detector of our own design, consisting of scintillator tiles and a counting device, to be flown on a high-altitude balloon to study the effects of high altitudes on the radiation levels
Pawsitive Learning Environments: Can Dogs Impact Student’s Mood?
No full textThe purpose of this study is to determine if having dogs in the classroom provides benefits to students’ emotional wellbeing. Many people report that animals help calm them down after a stressful day, so this study was devised as a way to determine if dogs can help alleviate the stressors that are often associated with school. During student teaching, I noticed positive changes in students’ behaviors on the days in which my service dog, Macy, was present. Both qualitative and quantitative data was collected from a class of seventh graders, who were asked to fill out daily surveys that recorded their emotions and any additional comments. Responses were averaged and compared in two categories: days with Macy present, and days without her. My goal as an educator is to provide a safe and welcoming classroom, and aside from answering the research question, this information will help me create that environment
The Impact of Technology in a Middle School Setting
No full textThe purpose of this study is to look into how technology impacts students’ education and motivation in English Language Arts. In 2020, COVID-19 caused technology to play an even larger role in students’ education. This action research paper determines how 1:1 technology impacts students’ attitudes and engagement. With a combination of reviewing literature and studying students’ responses, this research illustrates students’ genuine thoughts and experiences with technology in the classroom. Students’ concerns and also positive outlooks are apparent throughout the results. With the information collected, educators can see how students’ respond to the purposefulness of technology in the classroom. Educators can also create and implement instruction that best fits the students’ needs and interests involving technology. By utilizing student responses collected from a survey, one can see how students truly feel about technology and how technology is positively and/or negatively impacting students’ education and experiences in the classroom
The Effectiveness of a Small Rural School District’s Implementation of PBIS
No full textThis study investigates a rural school’s implementation of a Positive Behavior Interventions and Supports system. Data was collected through observation of student behavior in one first grade class in relation to the district\u27s application of a Positive Behavior Interventions and Supports system. Considering the PBIS framework is an evidence-based approach to improving the overall school climate, data was analyzed according to the students behavior in relation to the PBIS interventions applied. Based on the data and information gathered, this school’s implementation of PBIS was not very effective in correcting student behavior. Through this study, I was able to conclude the implementation was not consistent or significant enough to correct targeted behaviors
The Effects of Honokiol on HL-60 Acute Myeloid Leukemia
No full textAcute myeloid leukemia is a bone marrow and blood cancer affecting the body’s myeloblasts, red blood cells, and platelets, leading to anemia and weakness. High levels of HSP90 have been observed in leukemia during rapid cell proliferation. Research has shown that leukemia and other cancerous cells can be destroyed using the compound honokiol. Honokiol is a naturally occurring phenolic compound found in the bark of the Asian Magnolia tree and is commonly used as a dietary supplement. It has also been shown to downregulate HSP90. The aim of this study is to investigate the toxicity of honokiol in acute myeloid leukemia in conjunction with HSP90. When HL-60 acute myeloid leukemia cells are treated with varying doses of honokiol, significant cell death is observed in any dosage above 20 μM
Using CRISPR-Cas9 Techniques to Investigate Chick Limb Development
No full textCRISPR-Cas9 is used to investigate gene(s) underlying the limbless (ll) chick
mutant phenotype. The ll mutation has been mapped to an ~2.6 Mb region of chromosome 2. Genes in the targeted region suspected to have a role in limb development include: SP8, Twist1, and NUPL2. Target sequences for guide RNAs (gRNAs) were identified using an online tool and synthesized commercially. Double stranded oligos were ligated into the U6.3\u3egRNA.f+e plasmid. The newly ligated plasmid was transformed into competent cells, plated onto LB-ampicillin plates, and expanded in liquid culture. A mini prep was performed to isolate plasmid DNA to allow the gRNA production in cells of the chick embryo. Future plans include co-electroporating the oligo containing U6.3\u3egRNA.f+e plasmid with pCAGG\u3enls-hCas9-nls-GFP plasmid into HH14 chick forelimb fields. Embryos will be incubated for 24-48 hours to examine limb development compared to the controls
Factors Influencing the Use of Evidence-based Practice Resources Among Occupational Therapists Working with Adults with Traumatic Brain Injury in a Post-Acute Rehabilitation Setting: A Retrospective Cross-Sectional Analysis
Get PDFIn the post-acute rehabilitation setting for adults with traumatic brain injury, practitioners report inconsistencies in accessing and using evidence-based practice resources supportive of best practice. The objective of this study was to identify if level of education and number of years in practice influenced occupational therapists’ use of evidence-based practice resources during the evaluation and treatment of adults with traumatic brain injury within the post-acute rehabilitation setting. This retrospective cross-sectional analysis used de-identified data collected from a previous descriptive study that used an online survey to examine common practice patterns among occupational therapists working in post-acute rehabilitation settings for adults with a traumatic brain injury. Survey participants (n=27) were occupational therapists who had worked with adults with traumatic brain injury in a post-acute rehabilitation setting. This study examined possible relationships between occupational therapy practitioners’ level of education and number of years in practice on the implementation of evidence-based practice resources in the post-acute rehabilitation setting. Chi-square analysis indicated a statistically significant relationship, χ2(3, N=27) = 22.20, p=0.000059, between practitioner level of education and number of years in practice, as well as between level of education and frequency in accessing evidence-based practice resources, χ2(3, N=27) = 9.38, p=0.024. Implications for practice include evidence-based practice patterns are similar between practitioners based on level of education, and implementation of evidence-based practice resources should be a thoroughly defined expectation of practitioners. Occupational therapists working with adults with traumatic brain injury should apply evidence-based practice resources to support their practice

Teaching Self-Efficiency in a Fourth Grade Classroom
No full textA result of the recent COVID-19 pandemic, students have begun to decrease in their self-efficiency skills. When students lack self-efficiency, time is wasted in the classroom, calling for less time for instruction, and more time wasted getting started. The purpose of this quantitative study was to see if positive repetitions increased self-efficiency in a fourth grade class that has 92 students. When each class entered, they were tallied on how many people were immediately self-motivated. The results of this study concluded that positive affirmations had a positive effect on self-efficiency. The fourth grade class has shown fast improvements in their self-motivation. This class will benefit from this study with their newfound skill, taking it with them throughout the rest of their lives
