Open Educational Resources

Abstract:

This comprehensive analysis explores the dynamics of social groups and bureaucratic organizations, drawing on foundational theories and empirical studies to illuminate how structure, identity, and informal culture shape collective behavior. The paper examines the essential elements of group dynamics—regular interaction, defined roles, shared norms, and collective identity—alongside the four stages of group decision-making that guide consensus and effectiveness. It distinguishes between primary and secondary groups, emphasizing their respective influences on personal identity and social cohesion, and discusses the pivotal role of reference groups in identity formation.

Further, the discussion extends to the mechanisms of group survival, analyzing concepts such …

Major, Trace And Rare Earth Element Concentrations In Nist Standard Reference Material® 1646a Analyzed By Als Global Using Method Me-Ms61r, Jane L. Alexander

Publications and Research

This technical note compares analytical results obtained from ALS Global Method ME-MS61r with the certified and previously published results for NIST Standard Reference Material® 1646a, Estuarine Sediment. The results are grouped into major, trace and rare earth elements, and focus on elements used by sedimentary geochemists, for example in studies of sediment provenance. The results from ALS Global Method ME-MS61r are internally consistent and generally robust when compared with published analyses. However, acid digestion may not completely dissolve resistant minerals, leading to under-reporting of some elements such as Ti, Cr, Zr, heavy REE and Y.

Understanding Long Covid In National Community-Based Cohort: Symptom Clusters, Symptom Natural History, And Vaccine’S Role As A Prevention Tool, Yanhan Shen

Dissertations and Theses

BACKGROUND: Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), represents a growing public health concern with diverse symptom profiles, unclear risk factors, and evolving evidence on potential prevention strategies. Most studies of Long COVID have relied on electronic health records or convenience samples, which may underestimate mild or community-based cases and lack standardized follow-up, and often do not include pre-infection health information or complete infection histories. This dissertation leverages prospective data from a national community-based cohort to characterize the heterogeneity of Long COVID symptoms, assess symptom trajectories over time, and evaluate the effect of COVID-19 third dose vaccination on …

Interoceptive Forecasting And Recall: The Role Of Anxiety Sensitivity And Disgust Sensitivity, David Lloyd Yap

Dissertations, Theses, and Capstone Projects

Predicting and remembering emotional states (affective forecasting and recall) are adaptive processes that allow individuals to engage with the future and past to guide behavior, yet these processes are prone to bias. Although affective forecasting and recall biases are common across healthy populations, more pessimistically biased affective forecasts and recall have been linked to greater anxiety and depression symptom levels and to emotional disorders. A crucially understudied aspect of affective forecasting and recall is the perception of the somatic (interoceptive) symptoms that accompany emotions. This study investigated forecasting and recall accuracy of somatic symptom levels (i.e., interoceptive forecasting and recall). …

Potential Role Of A Ruthenium-Based Compound Ru-Im In The Treatment Of Triple Negative Breast Cancer, Rachele Rameau

Dissertations, Theses, and Capstone Projects

Triple negative breast cancer (TNBC) is an aggressive and heterogeneous molecular subtype of breast cancer that has limited available treatments. The organometallic cationic ruthenium derivative Ru-IM was found to be highly water soluble, was differentially toxic for breast cancer cells and tumors, and was involved in the pI3K/AKT/mTOR pathway. However, a full understanding of genetic and epigenetic factors that can be part of regulatory mechanisms of Ru-IM is yet to be determined. Epigenetic assays including DNA methylation, histone acetylation and histone deacetylation were performed with the half inhibitory concentration (IC50) values of Ru-IM. Bisulfite sequencing of untreated and treated MDA-MB-231 …

Enjoyment In The Classroom: Reciprocal Student-Teacher Dynamics In Israeli Math Education, Yonaton Gutterman

Dissertations, Theses, and Capstone Projects

Enjoyment is increasingly recognised as a keystone emotion in contemporary models of academic motivation and learning (Pekrun, 2006; Ryan & Deci, 2020). Grounded in Control-Value, Expectancy-Value, and Self-Determination theories, the present study tracked reciprocal affective processes in Israeli mathematics classrooms across ten lessons. Seven teachers and their 257 students (112 fourth-graders; 145 eighth-graders) completed parallel post-lesson questionnaires assessing feedback use, enjoyment, and perceived difficulty. Multilevel ordinal mixed-effects models, latent-growth curve models, and Bayesian random-intercept cross-lagged panel models were estimated to disentangle within-person fluctuations from between-person differences (Hamaker et al., 2015). Confirmatory-factor analyses supported scalar invariance of the key scales over …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …

Alerted And Anxious? The Effects Of Mobile Crime Alerts On Perceptions Of Personal And Public Safety, Amanda C. Benjamin

Dissertations, Theses, and Capstone Projects

Mobile crime alert platforms promise to enhance personal and public safety by delivering frequent notifications about nearby dangers—claims that, until now, have not been experimentally tested. For-profit applications like Citizen deliver real-time, geo-targeted push notifications about nearby crime incidents to over 9 million users, often operating outside the bounds of institutional oversight. Although marketed as tools to enhance awareness and protection, these platforms may simultaneously empower users through information while also potentially amplifying anxiety, heightening threat perceptions, and eroding trust in community. Despite their increasing prominence and integration into public safety communications, the psychological and behavioral impacts of mobile crime …

Performance Practice As Compositional Style: Wet Ink’S Collaborative Work, Carrie Frey

Dissertations, Theses, and Capstone Projects

In its twenty-five years in New York City’s new music scene, Wet Ink Ensemble has established a distinctive approach in which members blend the roles of performer, composer, and improviser. This dissertation investigates how the ensemble’s beginnings at the nexus of the experimental rock and avant-garde music scenes prepared it for a turn towards collaborative composition and improvisation. After defining essential elements of the ensemble’s performance practice, I analyze Eric Wubbels’ Auditory Scene Analysis (I) and Sam Pluta’s Lines on Black—compositions that exemplify opposing poles of notational specificity. I then trace the defined elements through two “Performance Practice” works, …

The project employs reflexive documentary techniques to weave together film analysis and personal narrative, investigating the central question: why didn't I …

Bmp Signaling Co-Regulation Of Immune Response And Lipid Metabolism, Katerina K. Yamamoto

Dissertations, Theses, and Capstone Projects

The Bone Morphogenetic Proteins (BMPs) are secreted peptide ligands of the Transforming Growth Factor beta (TGF-β) family, initially identified for their roles in development and differentiation across animal species. They are now increasingly recognized for their roles in physiology and infectious disease. In the nematode Caenorhabditis elegans, the BMP ligand DBL-1 controls fat metabolism and immune response, in addition to its roles in body size regulation and development. DBL-1 regulates classical aspects of innate immunity, including the induction of anti-microbial peptides. We theorized that BMP-dependent regulation of fat metabolism could also promote resilience against microbial pathogens. We found that …

Detecting Sonic Hedgehog Expression In The Adult Mouse Brain Using A Gene Expression Tracer, Kendra Stephens-Jones

Dissertations, Theses, and Capstone Projects

Sonic Hedgehog (Shh) is best known for its role in development, yet evidence supports Shh signaling plays a functional role in the adult brain. Previous work demonstrated that Shh is expressed by dopamine (DA) neurons in the ventral midbrain and that loss of Shh from these neurons leads to late-onset motor and structural abnormalities resembling Parkinson’s disease. However, the extent of Shh expression and its connectivity to the striatum in the adult mouse brain remain unclear due to the lack of reliable antibodies for Shh detection. To address this gap, the present study employed Shh ^L/L and DAT-Cre^+/- mice …

Inhibition Of Return And Attentional Blink: Aspects Of A Singular Attentional Process?, Kathleen Rowe

Dissertations, Theses, and Capstone Projects

Inhibition of Return (IOR) and Attentional Blink (AB) are two distinctly defined phenomena that display some intriguingly similar properties. They both describe suppression effects following a visual stimulus that has captured attention, both may be preceded by an enhancement, and both share partially overlapping effect time windows which can be manipulated by task difficulty. The current study attempted to measure the two phenomena simultaneously to test our hypothesis that behavioral indices of AB and IOR will display significant spatial and temporal overlap, suggesting the two phenomena may reflect, at least in part, different aspects of a singular attentional process. To …

Prerogative In Common: On The Emancipatory Potential Of Radical Mutuality Amid Sovereign Decisionism, Matthew Builes

Dissertations, Theses, and Capstone Projects

In times of crisis, liberal democracies resort to authoritarian measures that undermine core democratic values. Dominant thought in the study of emergency-era law and politics appeal to a dichotomy of normal and exceptional times, to critique or justify the turn to sovereign decisionism. While this strategy seems clear-cut, the persistence of exceptional spaces and the crises that supposedly generate them challenge existing frameworks by blurring the line between norm and exception. This project explores the prospect of radical mutual aid, as a transformative response to the enduring crisis of modernity.

Developments In The Lithographic Engineering Of Bi2sr2cacu2o8+Delta Mesa Terahertz-Emitting Devices, Sarah Elghazoly

Dissertations, Theses, and Capstone Projects

Devices microfabricated from the high-temperature superconducting cuprate Bi₂Sr₂CaCu₂O_8+𝛿 (Bi-2212) are a promising source of coherent terahertz radiation within the ’terahertz gap’ (0.3- 1.5 THz). A current-biased mesa patterned into the surface of a single crystal will produce electromagnetic radiation in the terahertz regime due to the naturally occurring Josephson junctions formed by the stacks of superconducting cuprate oxide planes in the material separated by insulating BiO and SrO barrier layers. Previous research has shown that by fabricating these mesas such that the geometry supports resonant cavity Fabry-Perot modes, the junctions within the mesa …

Brownsville Taught Me: Reframing The Public Memory Of Brownsville’S History, Amyleth J. Vargas

Dissertations, Theses, and Capstone Projects

Brownsville is a small neighborhood in eastern Brooklyn, New York, with a rich activist past. Community leaders and organizers have used the tenets of urban education, Black history, grassroots organizing, and community planning as the bases of their struggles for the expansion of justice and equality for Brownsville residents. This thesis discusses Brownsville’s rich history of activism. I use autoethnography, archival materials, and the theoretical framework of public memory to explore this rich history. The recovered stories about Brownsville that I recount here are designed to dispel misrepresentations of the community that have shaped the public memory of Brownsville. In …

How To Form A Gravitational-Wave Source: Quantifying Intermediate Evolutionary Stages In Isolated Binary Stellar Evolution, Ana Lam

Dissertations, Theses, and Capstone Projects

Gravitational-wave (GW) detections from double compact object (DCO) mergers provide crucial observational constraints for understanding massive stars across cosmic time. Coupled with these observations, binary population synthesis simulations become powerful tools for probing the formation, evolution, and ultimate fates of their progenitors---massive binary stars. However, complex evolutionary pathways, shaped by key intermediate stages such as mass transfer phases and supernovae, present a significant challenge to assess their impact. To address this, we develop a framework to quantify the influence of intermediate evolutionary stages on GW sources. By combining Sankey diagrams with survival factors, we systematically investigate how intermediate stages influence …

Low-Resource Ecoacoustic Audio Classification, Enis Berk Coban
