Access, Outcomes, And Sustainability In Seal Of Biliteracy Programs: Exploring Coordinators' Perceptions On Long Island, Faith Patricia Tripp

Theses & Dissertations

The New York State Seal of Biliteracy (SoBL) is an award recognizing high school graduates who demonstrate proficiency in English and at least one additional world language. Despite New York State's early adoption of the SoBL in 2012 and Long Island's regional leadership in awarding the seal, research suggests the credential disproportionately benefits White, English- dominant students rather than the multilingual learners it was originally meant to serve. Through semi-structured interviews with eight SoBL coordinators across fiscally and demographically diverse districts on Long Island, my study investigated how they described the program's value, the challenges and successes in implementation, and …

The Influence Of Defendant Mental Illness Characteristics On Prosecutorial Decision Making, Claire Elise Martin

Theses

As most criminal cases are now resolved via plea-bargaining, research on legal decision making has extended beyond the jury to evaluate judges, defense attorneys, and prosecutors. Although legal actors are obliged to remain objective and dispassionate, extralegal factors regarding defendant characteristics (e.g., age, gender, race/ethnicity, socioeconomic class) can influence case outcomes. Extant research on the effect of defendant mental health status and defendant demeanor on sentencing outcomes in court hearings is limited. Therefore, the present experiment solicited 134 prosecutors in a vignette study designed to assess how extralegal characteristics, specifically those related to mental illness, may affect the punitiveness of …

Application Of A Scale-Resolving Turbulence Model To Supersonic Retropropulsion Flows In Earth And Martian Atmospheres, Rebecca Thompson

Theses

The Blended Partially-Averaged Navier-Stokes (BPANS) turbulence model was used to simulate complex turbulent compressible flows seen in supersonic retropropulsion (SRP). The model was incorporated in the OpenFOAM solver sonicFoam to investigate SRP flows in Earth and Martian atmospheres. The new sonicFoam with BPANS was first tested for subsonic flows using the shear flow benchmark case of flow around a cylinder. Results show good agreement of velocity profiles with experimental values. SonicFoam was then validated for compressible flows using an experimental SRP configuration. Pressure coefficient distribution along the forebody and aft body of the geometry show good agreement with experimental results. …

Modeling And Characterization Of Pond And Fresh Ash Leaching In Citric Acid, Christina Fleming

Theses

Resourcing rare earth elements (REEs) from coal ash offers the opportunity to recycle industrial waste and reduce national dependence on foreign suppliers. In this research, the leaching behaviors of pond and fresh ash were studied to evaluate their suitability for REE recovery. Concentrations of REEs in leachates were measured and compared to kinetic models from literature, and the ash was analyzed using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) to characterize the observed behaviors. The pond ash leachate exhibited lower REE concentrations with steady release patterns, likely due to the acid resistant, REE-bearing aluminosilicate glass phases. In contrast, the …

Bubble equivalent diameters, positions, and velocities …

Optical Turbulence Estimation From Numerical Weather Prediction Models: Methods And Error Analysis, Richard Minor

Theses

Optical turbulence plays a critical role in electromagnetic wave propagation through the atmosphere, directly affecting imaging systems, wireless communications, and high-energy laser (HEL) performance. Realistic three-dimensional characterization of atmospheric turbulence is essential for understanding these impacts, particularly within the atmospheric surface layer, where turbulence is often strongest. The refractive index structure parameter, Cn2, is used to quantify optical turbulence. This thesis evaluates the capability of the High Resolution Rapid Refresh (HRRR) model to characterize surface layer Cn2. As the highest resolution and most frequently updated numerical weather prediction model covering the continental US, HRRR offers strong potential for operational HEL …

High Strain Rate Behavior Of Soft Polymeric Materials : Polymer-Bonded Explosive Simulants And Polyimide Aerogels, Benjamin Jeffrey Solomon

Theses

Soft polymeric materials exhibit strain sensitive behaviors and are used in various applications where dynamic loading conditions may be present, making understanding the responses at high rates vital to safe application. Investigation of the mechanical response of soft materials at high strain rates has proven challenging due to low forces, mismatching impedances, and longer times to obtain dynamic force equilibrium limiting the quality and accuracy of data acquisition. Two polymeric materials were evaluated in this study. The first is polymer-bonded explosive (PBX) 9501, which experiences dynamic loading during use as solid propellant and warhead explosive material. It is found that …

Intercomparison Of Remote Sensing Methods For Calculating Cn² Profiles, Isaiah Joseph Montgomery

Theses

Propagation of electromagnetic waves through the atmosphere is affected by turbulence. The impact of turbulence on wave propagation is characterized by the refractive index structure function (Cn²), which characterizes the intensity of fluctuations of the refractive index of air due to turbulence. Observations of vertical profiles of Cn² are essential for evaluating numerical model predictions. This study presents an intercomparison of Cn² derived from multiple ground-based remote sensing systems, including 915 MHz profiler, sodar, and a parameterized method that uses doppler wind lidar and radiometer. Results indicate that the sodar is the most accurate near- surface Cn² profiler, but above …

Influences Of Charge Structure And Storm Microphysics On The Relationship Between Optical And Vhf Lightning Observations, Kaitlyn Wheeler

Theses

Lightning observations provide valuable insight into convective intensity, storm structure, and microphysical processes. Much of the current understanding of lightning-convection relationships is derived from ground-based very high frequency (VHF) measurements, while space-based optical observations remain comparatively new. This study investigates how storm charge structure and microphysics influence observed optical lightning emissions using coordinated observations from the 2017 GOES-R Post Launch Test campaign. Optical measurements from the Fly’s Eye Geostationary Lightning Mapper Simulator were combined with Lightning Mapping Array observations for ordinary multicell storms exhibiting a normal charge structure on 18 April 2017 and a supercell exhibiting an anomalous charge structure …

Impacts Of Vertical Wind Shear And Coastal Friction On The Pre-Landfall Rapid Intensification Of Hurricane Nicholas (2021), Ethan O. Prunty

Theses

Predicting tropical cyclone (TC) rapid intensification (RI) under moderate-to-strong vertical wind shear (VWS) remains challenging, particularly when cyclogenesis and RI occur within 48 hours of landfall, as with Hurricane Nicholas (2021). This study analyzes Nicholas’ RI using NOAA’s Hurricane Analysis and Forecast System. Results reveal a two-stage vortex alignment before the early RI stage: diabatic heating first draws the mid-level center toward the low-level center, followed by cyclonic precession. A nearly-saturated core below 500 mb develops before RI onset as column-integrated moist static energy (MSE) increases, and the moistening process continues during the early RI stage as surface heat and …

Effects Of Energetic State On Male Mating Preferences In Poeciliid Fishes With Differing Mating Strategies, Katherine E. Taylor

Theses

Reproduction is energetically costly, making condition (i.e., energetic state) a potential factor in shaping reproductive behavior. However, its role in male mate choice remains largely unexplored. Here, we investigate condition-dependent effects on male mate choice in two species of Poeciliids: one coercive species (Gambusia affinis) and one courting species (Xiphophorus hellerii). Diet treatments were used to manipulate male and female conditions, and male preferences were assessed in dichotomous-choice tests using animated female stimuli. X. hellerii males showed a preference for high-condition females, whereas G. affinis males showed no overall net preference. Diet influenced preference in G. affinis, with high-fed males …

Examining The Multilevel Effects Of Instructional Leadership On Teachers’ Professional Commitment And Classroom Management, Nuruddin Ahmed Masud, San Su Su San, Kim Ki Bong, Mst Taherun Nesa Subarna

Georgia Educational Researcher

This study examined the multilevel effects of instructional leadership on teachers’ professional commitment and classroom management in secondary schools. Using a multilevel modeling (MLM) approach, data were collected from 250 teachers nested within 8 schools. The analysis assessed the influence of both school-level instructional leadership and teachers’ perceptions of leadership on professional commitment and classroom management outcomes.

Results indicated that instructional leadership at both levels significantly predicted teachers’ professional commitment (teacher-level: β = .32, p < .001; school-level: β = .45, p < .001). Similarly, instructional leadership demonstrated significant positive effects on classroom management (teacher-level: β = .28, p < .001; school-level: β = .41, p < .001). Furthermore, teacher professional commitment was positively associated with classroom management (β = .36, p < .001) and moderated the relationship between instructional leadership and classroom management, such that the effect was stronger under higher levels of leadership support.

These findings highlight the importance of instructional leadership in shaping teacher-related outcomes across organizational levels. The study contributes to the literature by providing empirical evidence …

The Ambitions Of History And Tradition In And Beyond The Second Amendment, Joseph Blocher, Reva B. Siegel

Faculty Scholarship

This Article examines the ambitions of history-and-tradition review in and beyond the Second Amendment. In Bruen and Rahimi, the Roberts Court rejected means-end review in favor of a historical-analogical approach, claiming to constrain the exercise of judicial discretion and thus to promote the democratic decisions of the founders. But our examination of these cases shows that the Court has created new opportunities for judges to advance their values in considerably less transparent ways. We identify contexts in which Second Amendment doctrine enables judicial discretion, key among them that it allows judges to reason about gun rights and regulation at disparate …

Drawing And The Pursuit Of Progress In The Late 19th-Century Dominican Republic, Felix V. Rodriguez Suero

Faculty Publications – Art

Eugenio Maria de Hostos, with the support of late 19th-century Dominican liberals, spearheaded the transition from scholastic education to an education grounded on scientific principles and liberal ideals. Through the discussion of four fundamental principles for drawing instruction in Hostos’s educational project, I examine why teaching young people drawing skills was central to his anticolonial political project. Drawing from decolonial and critical frameworks, I analyze the connection between art classes in schools and the political struggles to democratize and modernize Dominican society. I argue that, despite seemingly good intentions, the influence of Western philosophy and 19th-century scientific rationalism led Hostos …
