Two new epimeric bibenzylated monoterpenes machaerifurogerol (1a) and 5-epi-machaerifurogerol (1b), and four known isoflavonoids (+)-vestitol (2), 7-O-methylvestitol (3), (+)-medicarpin (4), and 3,8-dihydroxy-9-methoxypterocarpan (5) were isolated from Machaerium Pers. This plant was previously assigned as Machaerium multiflorum Spruce, from which machaeriols A-D (6-9) and machaeridiols A-C (10-12) were reported, and all were then re-isolated, except the minor compound 9, for a comprehensive antimicrobial activity evaluation. Structures of the isolated compounds were determined by full NMR and mass spectroscopic data. Among the isolated compounds, the mixture 10 + 11 was the most active with an MIC value of 1.25 μg/mL against methicillin-resistant …

In What Ways Can Play-Based Learning In Preschool And Kindergarten Classrooms Support Healthy Development?, Angela Bjelde

Graduate Teacher Education

Play-based learning was identified as a developmentally appropriate practice (DAP) within early childhood education (ECE) (NAEYC, 2009). This paper examined current research to determine the impact of play-based learning on the development of preschool and kindergarten children. According to research, play offers effective, innovative approaches to pedagogy that meets children’s diverse needs as a whole learner. Although research has underlined the importance of play for the future of ECE, a number of diverse challenges have created difficulty with implementing play-based learning in preschool and kindergarten classrooms. Most early childhood educators have faced increasing difficulty with advocating for play given the …

Modeling Residence Time Distribution Of Chromatographic Perfusion Resin For Large Biopharmaceutical Molecules: A Computational Fluid Dynamic Study, Kevin Vehar

KGI Theses and Dissertations

The need for production processes of large biotherapeutic particles, such as virus-based particles and extracellular vesicles, has risen due to increased demand in the development of vaccinations, gene therapies, and cancer treatments. Liquid chromatography plays a significant role in the purification process and is routinely used with therapeutic protein production. However, performance with larger macromolecules is often inconsistent, and parameter estimation for process development can be extremely time- and resource-intensive. This thesis aimed to utilize advances in computational fluid dynamic (CFD) modeling to generate a first-principle model of the chromatographic process while minimizing model parameter estimation's physical resource demand. Specifically, …

Designing And Teaching Adaptive+Active Learning Effectively, Peter Van Leusen, James Cunningham, Dale P. Johnson

Current Issues in Emerging eLearning

To fulfill the promise of providing all learners with access to education, institutions of higher education are exploring personalized learning for individuals with different skills, abilities, and interests. These universities have turned to an instructional model that combines adaptive courseware and learner-centered instruction. This is often referred to as active learning. Despite growth in adaptive courseware and generous support through national organizations, successful implementation of adaptive systems is mixed (SRI Education, 2016). This article highlights the need for a systems approach and illustrates this approach through design and pedagogy decisions that have contributed to the success of adaptive learning at …

Reciprocal Empathy: Reversing Antipathy Towards Immigrants In Emotion And Votes, Amanda Gach

Undergraduate Honors Theses

The topic of immigration politics has gained traction in recent years as surges of immigrants are introduced to new homes—often with a long road of integration into the host country ahead. As a result, debates emerged on how to effectively “humanize” members of these outgroups – which include immigrants and refugees alike—while also being able to forge lasting cooperation between these ethnic groups allowing for peaceful integration. Previous attempts to achieve this goal have used various forms of visual and sensory media to generate empathy towards these outgroup members. These approaches have proven to be ineffective when not met with …

The Rhetoric Of Jimmy Carter: Renewing America’S Confidence In Civic Leadership Through Speech And Political Education, Christopher Bondi

Electronic Theses and Dissertations

July 15, 2019 marked the fortieth anniversary of President Jimmy Carter’s “Crisis of Confidence” speech, a catalyst for what became an often overlooked yet significant turning point in the nation’s history. Carter’s words were both poignant and pointed as he calmly, yet directly, addressed the nation’s dependence on fossil fuels and engagement in narcissistic practices that led to a coveting of material goods. In an examination of the events that shaped this historical moment, this dissertation contends that, despite President Carter’s attempt to steer America in a more environmentally and socially conscious direction, the nation instead acquiesced to Ronald Reagan’s …

Functionalized Materials From Atom Transfer Radical Processes, Sean Fischer

Electronic Theses and Dissertations

This work is focused on the synthesis, characterization, and application of functionalized materials prepared from atom transfer radical processes. Atom transfer radical processes encompass both atom transfer radical addition (ATRA) and polymerization (ATRP) reactions, both of which are catalyzed by ppm amounts of copper complexes. The synthetic efforts of ATRA include increasing adduct selectivity through optimization of reaction conditions to generate small molecules in high to moderate yields. ATRA provides retention of the halogen moiety, which is an attractive functional group that can be further modified with other transformations. Specifically, the copper-catalyzed azide-alkyne [3+2] cycloaddition (CuAAC) allows for the realization …

Railspace: A Geocritical Study Of The Railroad Through American Literature And Culture, Michael A. Smith

Electronic Theses and Dissertations

This dissertation uses geocriticism to argue that the American railroad is best understood as a set of discursively constructed railspaces formed through a variety of viewpoints, a polysensorial awareness of space, and stratified social relationships and power struggles. This study takes up four railspaces, the constituent texts of which demonstrate how intertextual discourse shapes and is shaped by the railroad. The observation car, charted through California Zephyr advertisements and Muriel Rukeyser’s “Campaign,” is an apparatus that produces perpetual spectacle. Three novels—Sister Carrie by Theodore Dreiser, Double Indemnity by James M. Cain, and Strangers on a Train by Patricia Highsmith—and …

Absolute Quantification Of Transcription Factors In Human Erythropoiesis Using Selected Reaction Monitoring Mass Spectrometry., Mark A Gillespie, Carmen G Palii, Daniel Sanchez-Taltavull, Theodore J Perkins, Marjorie Brand, Jeffrey A Ranish

Articles, Abstracts, and Reports

Quantitative changes in transcription factor (TF) abundance regulate dynamic cellular processes, including cell fate decisions. Protein copy number provides information about the relative stoichiometry of TFs that can be used to determine how quantitative changes in TF abundance influence gene regulatory networks. In this protocol, we describe a targeted selected reaction monitoring (SRM)-based mass-spectrometry method to systematically measure the absolute protein concentration of nuclear TFs as human hematopoietic stem and progenitor cells differentiate along the erythropoietic lineage. For complete details on the use and execution of this protocol, please refer to Gillespie et al. (2020).

Implementation Of Green Marketing Concept Throughsocial Media Activities: A Systematic Literature Review, Elnur Nabivi

Journal of Marketing and Consumer Behaviour in Emerging Markets

The last century’s industrial and technological development has led to the growth of environmental problems such as global warming, climate changes, water, air, and ground pollution. The awareness of modern consumers about these issues is growing, and companies respond by using “green marketing” strategies. Green marketing refers to the development and marketing of products that are considered environmentally safe. Furthermore, the extensive use of the Internet and increasing social media’s importance in recent years forced brands to communicate with consumers in this way. In this study, these two mega-trends influencing contemporary consumer behavior were combined: social media and green marketing. …

The Portrayal Of African Immigrants: A Framing Analysis Of Newspaper Coverage, Oluwatosin Arowosola

A Crisis Of Kelp, Rachel L. Sherman

Capstones

Along with insects and lab-grown meat, for years seaweed has been lauded as a sustainable “food of the future” by the U.N. Food and Agricultural Organization. As the world increasingly turns to alternative foods in pursuit of a healthier Earth, seaweed has all the makings of an ecological savior. It’s plentiful — seaweeds and ocean algae make up roughly nine tenths of all the plant life on Earth — it’s cheap to harvest and get to market, packed with nutrition, and keeps oceans clean, absorbing more carbon dioxide and releasing more oxygen than the world’s rainforests.

Not Everyone Is Welcome In The Blue Light District, Kathryn J. Herchenroeder

Capstones

The pandemic has fundamentally altered the way people do their jobs; and this is especially true for sex workers. While some women have seen exponential increases in their income during the coronavirus crisis, thanks to online sex work platforms like OnlyFans, others have faced insurmountable odds in their fight to earn a living wage and stay alive. "Not Everyone is Welcome in the Blue Light District" tells the story of why sex workers in Latin America don't have access to new innovations in sex work, and what this disparity looks like transnationally.

Engaging With Arabic Speaking Refugee Mothers, Rawan Yaghi

Capstones

In my research and interviews throughout my Practicum, the topic of refugee representation in the media was frequently discussed. The most common narrative around refugee lives constructs them as dehumanised victims. In an article for The Independent, Emily Cousens writes about the portrayal of the so-called “good” and the “bad” refugee -- in other words, the refugees who are deemed deserving of reception, and those who are not. Cousens reflects upon how the photo of a dead refugee child on the shore of Turkey sparked a wave of global interest in the issues that refugees were facing. She highlights …

A Latinx Religion By Another Name: How Latinas Lead The Un-Monolithic Conversion To Islam, Ambar Castillo

Capstones

This is a story about two Latina Muslims--a formerly Islamophobic young Peruvian Baptist missionary, a middle-aged Afro-Dominican woman in recovery from substance use--who met at a crossroads. It is also a story about what happened after: pre-pandemic, the unsafe safe spaces for converts that led them to start their own support group; post-pandemic, the sparks of a transnational movement of Latina Muslims at a time when political pundits were just recognizing the fallacy of a monolith of “Latinos.”

From an unconscious-bias workshop in a cramped Astoria, Queens apartment to Zoom meetings of Latina Muslims nationwide and from Mexican villages with …
