Leadership And Instructional Coaching: A Synthesis Of Approaches And Practices That Promote Change, Katie L. Perkins

Essays in Education

The aim of this educational essay is to provide a literature-based synthesis of the leadership approaches and practices of instructional coaches that best support teacher development. The essay is grounded in transformational leadership theory (Bass & Avolio, 1990) and synthesizes three main constructs for effective instructional coaching. These constructs include: andragogical practices (Knowles, 2015), the ethics of care (Beck, 1994), and organizational change (Burke, 2014). Incorporating these leadership practices may encourage effective teacher-coach relationships, promote teacher development and retention, and ultimately increase student success.

Efficient Communication In Organizations, Federico Vaccari

Fondazione Eni Enrico Mattei Working Papers

Organizations design their communication structures to improve decision-making while limiting wasteful influence activities. An efficient communication protocol grants complete information payoffs to all organization members, thereby overcoming asymmetric information problems at no cost. This paper characterizes efficient protocols assuming that: (i) some agents within the organization have the knowledge required for optimal decision-making; (ii) both the organization and consulted agents incur losses proportional to the exerted influence activities; and (iii) informed agents can discuss their strategies before being consulted. Under these assumptions, “public advocacy” is the unique efficient communication protocol. This result provides a novel rationale for public advocacy.

Effects Of Exposure To Atmospheric Humidity On Breakdown Field Strength Measurements Of Polymers, Megan Loveland Dewaal

Fall Student Research Symposium 2022

This study investigates the effects of absorbed water introduced via exposure to atmospheric humidity on electrostatic breakdown field strength measurements of polymers. Conducting breakdown tests under sample conditions appropriate for different applications is essential. If the breakdown field strength is overestimated for an application, an insulator may be used inappropriately in high electric fields where they are more likely to break down. Comparisons are made between: sets of pristine samples, samples that underwent a thorough vacuum bake out to evaporate absorbed water, and samples subject to subsequent incremental prolonged atmospheric exposure. These investigated the effects of absorbed water and determined …

Investigating The Color-Changing Properties Of Poly-Phenyl Sulfide, Dallen Dewaal

Fall Student Research Symposium 2022

Investigating the Color-Changing Properties of Poly-Phenyl Sulfide Dallen DeWaal, Megan Loveland DeWaal, Heather Allen, JR DennisonMaterials Physics Group, Physics Department, Utah State UniversityAbstractWhile preparing samples of FortronTM PPS (poly-phenyl sulfide) for spacecraft charging testing, it was discovered that the polymeric dielectric material exhibits color-changing properties from mechanical forces while shearing and bending. Given enough time, PPS reverts from blue-green back to its original tan color. PPS samples were characterized by the magnitude of color change and recovery time. PPS samples were subjected to multiple tests to discover which forms of energy input activate the color change, and which (if any) …

How Does Perceived Human Instability Affect One's Own Stability?, Madi Braunersrither

Fall Student Research Symposium 2022

Participants were prompted to evaluate the stability of pictured human postures while standing on a force plate. We measured irregularity by analyzing the presence of patterns in the sequential center of pressure values. To measure the presence of patterns, sample entropy, a time series statistic, was developed and we utilized it on the force plate data. Does one's own stability change when viewing a posture deemed unstable? Is Sample Entropy (SampEn) an effective tool to determine stability? This relationship could have implications for modeling the progression of motor skills, understanding human development, and the design of environments for rehabilitation.

The Stigma Against Elderly Drivers And An Analysis Of The Effects Of Age On Driving Ability, Alexander Lee

Fall Student Research Symposium 2022

Elderly drivers are not as big of a danger on the road as the general population believes. This was preliminary research into the significance of elderly drivers on the road and the statistical data on whether they are a hazard on the road. They are among the minority of people that are in car accidents and most elderly people still on the road are more experienced and drive safer to compensate for ailments they may experience from their age. Elderly that can not drive safely or can pose a hazard on the road usually remove themselves from driving or are …

Perceived Factors Contributing To The Subjective Wellbeing Of Undergraduate Engineering Students: An Exploratory Study, Muhammad Asghar, Angela Minichiello, Assad Iqbal

Engineering Education Student Research

Engineering education is perceived to be a tough field of study with detrimental effects on the mental health of undergraduate engineering students. High levels of anxiety and depression are reported among this population. Overall, mental health research is often biased toward looking at mental health from a deficit perspective and investigating mental health as a negative phenomenon. This trend also persists in engineering education research. The purpose of this exploratory study, therefore, is to investigate the condition of subjective wellbeing (SWB) of undergraduate engineering students to understand the factors that they perceive as positively contributing to their overall wellbeing in …

Closing The Concern-Action Gap Through Relational Climate Conversations: Insights From Us Climate Activists, Julia Coombs Fine

Environmental Studies Faculty Publications

Several studies have found that relational climate conversations can be an effective method of increasing conversational participants’ concern about the climate crisis and encouraging them to take collective action. However, little work has yet examined how such conversations are practiced by climate activists, a group with expertise in relational organizing. Drawing on surveys and semi-structured interviews with climate activists across the USA, this analysis finds that activists frequently have climate conversations with friends and family, most of whom are politically progressive and somewhat to very concerned about the climate crisis. These findings might seem to suggest that climate activists only …

Although machine learning (ML) has shown promise across disciplines, out-of-sample generalizability is concerning. This is currently addressed by sharing multi-site data, but such centralization is challenging/infeasible to scale due to various limitations. Federated ML (FL) provides an alternative paradigm for accurate and generalizable ML, by only sharing numerical model updates. Here we present the largest FL study to-date, involving data from 71 sites across 6 continents, to generate an automatic tumor boundary detector for the rare disease of glioblastoma, reporting the largest such dataset in the literature (n  =  6, 314). We demonstrate a 33% delineation improvement for the surgically …

Light Scattering From Periodic Conducting Nanostructures, Wesley Mills

Fall Student Research Symposium 2022

Carbon nanotube (CNT) forests are roughly vertically aligned carbon tubes with a diameter of a few nanometers, and a height of hundreds of micrometers. CNT forests of proper densities and heights can be excellent absorbers of visible light, so a lot of interest has been generated in their application in optical calibration, energy conversion, antireflection, and radiometry. Unfortunately, reflectance from CNTs rises quickly above the mid-infrared range, limiting their present use. Improving a CNT-based broadband absorber requires understanding why the forests have almost zero visible-light reflectance, as well as a strategy to extend that low reflectance into longer wavelengths. Since …

The Effect Of The Plant-Based Diet On Athletes And Its Limitations, Dylan Hill

Fall Student Research Symposium 2022

In this study, I was hoping to learn more about the differences between the omnivore diet and plant-based diet in relation to the effects on an athlete. Research was conducted using library and internet resources to locate both primary and secondary research. For this study, personal accounts and experiences of athletes who had experimented with a plant based diet were examined. Research showed that although a very enticing option for a healthy diet for athletes, the plant-based diet is just as effective as a balanced omnivore diet but much more difficult to do properly and is much less accessible to …

Assessing The Performing Arts Experience At A Stem-Based Institution, Benjamin Willmott

Theses

Past studies examined the role of performing arts within a STEM-based curriculum, but there has been little research to date on how to fully integrate the two into one unified program at the higher education level. A qualitative study was conducted utilizing a phenomenological approach vis-à-vis four focus groups with students engaged in the Performing Arts Scholarship Program at Rochester Institute of Technology in Rochester, NY. The commitment-trust theory of relationship marketing as well as self-efficacy theory were considered to ground the theoretical framework surrounding the success of the program and the experiences of a sample of 951 Performing Arts …

Preparation Of In-Situ Bimetallic Coni Nanoparticles Suppurated On Carbon Nanotubes As Effective Catalyst For H2 Generation From Sodium Borohydride, Ahmed M. Abd-Elaal, A. A. Alsarawy, M.M. El-Halwany, Mahmoud H. Mahmoud

Mansoura Engineering Journal

Multiwall carbon nanotubes (MWCNTs) enhanced Co-Ni catalysts for NaBH4 hydrolysis were developed and produced in this research. The microscopes utilized was transmission electron microscope. The various species located at the surfaces of some selected catalysts has been characterized using the X-ray photoelectron spectrometer. The results reveal that even with the addition of carbon nanotubes as a promoter, the catalysts maintain an amorphous shape. In Co-Ni catalysts (NiCo@MWCNTs), however, the right amount of MWCNTs promoter results in a large specific surface area, fine dispersion of active components, more active sites, and a high electron density at active sites. Furthermore, hydrogen overflow …

Methane Emissions From Agricultural Ponds Are Underestimated In National Greenhouse Gas Inventories, Martino E. Malerba, Tertius De Kluyver, Nicholas J. Wright, Lukas Schuster, Peter I. Macreadie

Climate Science Research Articles

Agricultural ponds have some of the highest methane emissions per area among freshwater systems, and these anthropogenic emissions should be included in national greenhouse gas inventories. Here we deliver a continental-scale assessment of methane emissions from agricultural ponds in the United States and Australia. We source maps of agricultural ponds, compile a meta-analysis for their emissions and use published data to correct for temperature and the relative contributions of two methane fluxes (diffusion and ebullition). In the United States, 2.56 million agricultural ponds cover 420.9 kha and emit about 95.8 kt year−1 of methane. In Australia, 1.76 million agricultural ponds …

Behaviors For Which Deinonychosaurs Used Their Feet, Alexander King

Honors Projects

This paper seeks to show for what purpose deinonychosaurs used their feet. Fowler et al., (2011) showed that D. antirrhopus’s feet were closest in function to accipitrids, as they found it was more built for grasping prey than running.

I answered this question by using 2D images of the feet of three modern birds (Buteo jamaicensis, Phasianus colchicus, and Gallus gallus domesticus), one eudromaeosaur (Deinonychus antirrhopus), and one troodontid (Borogovia gracilicrus). I used ImageJ to apply 73 landmarks to each foot, capturing the variation between species in the metatarsals and pedal phalanges. These data were then uploaded to the software …

Poisson Hurdle Model-Based Method For Clustering Microbiome Features, Zhili Qiao, Elle Barnes, Susannah Tringe, Daniel P. Schachtman, Peng Liu

Department of Agronomy and Horticulture: Faculty Publications

Motivation: High-throughput sequencing technologies have greatly facilitated microbiome research and have generated a large volume of microbiome data with the potential to answer key questions regarding microbiome assembly, structure and function. Cluster analysis aims to group features that behave similarly across treatments, and such grouping helps to highlight the functional relationships among features and may provide biological insights into microbiome networks. However, clustering microbiome data are challenging due to the sparsity and high dimensionality.

Results: We propose a model-based clustering method based on Poisson hurdle models for sparse microbiome count data. We describe an expectation–maximization algorithm and a …

A Finite Difference Approach To Study The Impact Of Boundary Conditions On The Acoustical Behavior Of Particle Stacks, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

The responses of particle stacks to incident sound waves show interesting features that are very different from those of a homogeneous continuum. Further studies of the acoustical performance of particle stacks can help both to discover potential noise control applications of these types of materials, and to help provide better insight into the internal status of the particle stacks. In the current study, a finite difference (FD) model for a particle stack was built based on the Biot poro-elastic theory. The intention in developing this model is to describe the acoustical behavior of particle stacks with consideration of not only …

Six-Dimensional Single-Molecule Imaging With Isotropic Resolution Using A Multi-View Reflector Microscope, Oumeng Zhang, Zijian Guo, Yuanyuan He, Tingting Wu, Michael D. Vahey, Matthew D. Lew

Electrical & Systems Engineering Publications and Presentations

Imaging of both the positions and orientations of single fluorophores, termed single-molecule orientation-localization microscopy, is a powerful tool for the study of biochemical processes. However, the limited photon budget associated with single-molecule fluorescence makes high-dimensional imaging with isotropic, nanoscale spatial resolution a formidable challenge. Here we realize a radially and azimuthally polarized multi-view reflector (raMVR) microscope for the imaging of the three-dimensional (3D) positions and 3D orientations of single molecules, with precisions of 10.9 nm and 2.0° over a 1.5-μm depth range. The raMVR microscope achieves 6D super-resolution imaging of Nile red molecules transiently bound to lipid-coated spheres, accurately resolving …

A View Into Secondary Education Mathematics, Thomas Krieger Jr.

Honors Theses

Teaching methods, and the effects they can have on students, are important to consider for a classroom because when teaching you should allow for every student to have an opportunity. Every student should feel encouraged in the classroom, however not every method may allow for that. An important task for a teacher is to find out how to reach their students in their classroom; be it adapting methods or choosing when to implement one item over another. This task differs with every student that enters the classroom as no student is the same. Every students’ differences stem from their academic …

Probing Conformational Landscapes And Mechanisms Of Allosteric Communication In The Functional States Of The Abl Kinase Domain Using Multiscale Simulations And Network-Based Mutational Profiling Of Allosteric Residue Potentials, Keerthi Krishnan, Hao Tian, Peng Tao, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

In the current study, multiscale simulation approaches and dynamic network methods are employed to examine the dynamic and energetic details of conformational landscapes and allosteric interactions in the ABL kinase domain that determine the kinase functions. Using a plethora of synergistic computational approaches, we elucidate how conformational transitions between the active and inactive ABL states can employ allosteric regulatory switches to modulate intramolecular communication networks between the ATP site, the substrate binding region, and the allosteric binding pocket. A perturbation-based network approach that implements mutational profiling of allosteric residue propensities and communications in the ABL states is proposed. Consistent with …
