Ethical Leadership Through Cooperative Reasoning
No full textAdversarial methods of argumentation on social identity have long pervaded human interaction. But what if there was another way? Dr. Coleen Zoller Ph.D. and I attempt in this project to provide a collaborative method in hopes of better leadership. Using modern philosopher, Maureen Linker’s technique we workshopped with instrumental leaders and staff. From her theory we draw that effective communication includes acknowledging unique intersections of privilege and identity while simultaneously opening yourself to transformation. We employ vulnerability, truth, and metacognition to arrive at collaboration
Do spiders use plant essential oils as repellents or attractants for preferred vegetation?
No full textSpiders are associated with particular plant species but it remains unknown if volatile plant oils serve as spider attractants or repellents or if spiders use these airborne plant cues to find appropriate habitat. Tetragnatha laboriosa prefers tall grass in dry fields while T. viridis is found on conifer trees. The crab spider, Mecaphesa asperata chooses blooming flowers within these sites. Using proximity tests, we measured spider attraction or repellency to essential oils from Citronella grass (Cymbopogon nardus), Goldenrod (Solidago canadensis), Black Spruce (Picea mariana), and Scots pine (Pinus sylvestris). Spiders of each species were tested for one hour across each of all four extracts. We found strong differences in extract repellency and attraction across species with significant species and extract type interactions. Our results indicate that plant volatiles may serve as important attractants and repellents for spiders and that spiders could use plant volatiles to locate preferred microhabitats
Investigation of Functionally Important Residues in Histone Variant H2A.Z and the Effect of Rapamycin on Saccharomyces Cerevisiae
No full textHistones are involved in the compaction of DNA and require modification to allow for normal DNA processes. One way this is done is through placement of histone variants. When wild type and yeast cells without variant H2A.Z are grown with rapamycin, a genotoxic stressor, gene expression is impacted. An rt-PCR was performed to investigate the expression of genes MEH1 and LST8, known to be involved in DNA damage response and replication. There was an increase in expression of both genes in H2A.Z yeast. We then questioned how yeast differentiate placement of H2A.Z and its canonical counterpart H2A, and the differences between them were investigated. A sequence alignment was performed and several residues unique to H2A.Z and conserved across species including T87 were identified. The expression of MEH1 and LST8 was also affected in the T87 mutants. These findings indicate that the T87 residue is important for the functionality of H2A.Z
Comparing baseline sedimentation rates in paired perennial streams under different land uses during high precipitation events
No full textSediment and nutrient delivery are primary impairments of the Chesapeake Bay. These threats are produced in the agricultural landscapes in the Susquehanna River watershed. Best management practices (BMP’s) such as riparian buffers and livestock exclusions are used in stream restoration projects. This study presents the sediment transportation characteristics of paired micro-watersheds in unnamed tributaries to Elk Creek in Centre County, Pennsylvania before stream restoration. Water samples were collected every six hours by autosamplers at upstream and downstream locations on a barnyard where restoration will begin next year, and a forested reference site. Samples were analyzed for field parameters, turbidity, and sediment content using hydrometers to estimate suspended sediments according to their size. During heavy rain, the two watersheds often had similar turbidity, but the agricultural stream carried far more fine particles than the forested site. This study will be repeated after stream restoration to determine the effectiveness of the BMP’s
How Yoga Techniques Benefit Elementary Students
No full textThis presentation focuses on the importance of using yoga techniques inside the everyday classrooms. In more recent years, it has been noted that yoga has had many positive effects on the lives of adults. Researches have noticed these benefits and wanted to see if the same benefits occur as much for children as they did for adults. This presentation will focus on the benefits yoga has on elementary age children and how to correctly administer yoga in the classroom. Throughout this presentation I will answer the questions: (1) What are the academic benefits of using yoga in the classroom? (2) How can yoga promote self-regulation for students? (3) What techniques should teachers and instructors be using during yoga intervention? These questions play an important role in spreading awareness of the benefits yoga may have on classrooms around the world
School and Community Programs Impact on Financial Literacy
No full textThe importance of being able to measure financial literacy among high school students has been increasing. With the lack of adequate assessments, it is hard to measure the effectiveness of enacted legislation within the United States on financial literacy education. This study focuses on school districts in Pennsylvania due to poor performances of adequately preparing students with personal financial guidance. By looking at afterschool and community programs, these variables may increase the chances of a student having higher financial knowledge. From creating a new model and analyzing the data, the results are inconclusive whether afterschool and community programs have an impact on increasing higher financial literacy with the current data collected
Techniques of Classical Mechanics: From Lagrangian to Newtonian Mechanics
No full textSamya Zain\u27s work fulfils the niche that connects introductory physics level books, like Phyiscs by Halliday, Resnick and Krane, to graduate level books like Analytical Mechanics by Fowles and Cassiday and The Variational Principles of Mechanics by Cornelius Lanczos. The book has been class-tested on Samya\u27s own students on her Newtonian Mechanics course at Susquehanna University, and is accompanied by her own website, which features problems and exercises that will be regularly updated to match students\u27 needs. This book serves as an excellent stepping stone from level 1 introductory physics to graduate level physics and provides a level field for the various techniques used to solve problems in classical mechanics, and to explain more simply the Lagrangian and Hamiltonian methods, and it is a must for junior and senior physics undergraduates.https://scholarlycommons.susqu.edu/facultybooks/1085/thumbnail.jp
Relationship between discharge and %EPT in the upper main stem of the Susquehanna River during the fall semesters from 2016 to 2018
No full textIn this study, we continued the tenth year of a long-term study of benthic macroinvertebrate communities (BMI) in the upper main stem of the Susquehanna River. By sampling these communities, we performed river quality assessments and observed habitat variation between the different zones of the river. The study sites were on the western side of the Byers Island transect near the Sunbury Generation LP in Shamokin Dam, PA. Site 1 was located within the West Branch plume while Site 2 was within the North Branch plume. We followed EPA guidelines for passive sampling in non-wadable streams using rock baskets. River discharge was used to reflect stochastic seasonal trends. We saw a rise in %EPT from over the three years from 45.5% to 83.5%, however a slight increase in HBI was also observed. A Bray-Curtis test showed that 2016 and 2017 were the most similar with 2018 being the most dissimilar
A Positive Classroom Environment
No full textCreating a positive classroom environment should be a daily priority for teachers to define values and expectations that leave students feeling socially, emotionally and physically comfortable to learn in the classroom. It is crucial for teachers to see the classroom as a safe environment for students to be learning in and make sure each individual student is receiving positive support to learn. This study showed how creating a positive classroom environment affected my own teaching practices. The information found on creating a positive classroom climate demonstrates improvement in both the learning experiences for students and my own teaching practices. This study focused on different classroom management techniques, particular elements in the classroom, and motivational strategies for students to keep the learning environment a positive place
