Luminescence from Metal-Organic Frameworks: Structural Modification and Small Molecule Uptake
Full text linkMetal-Organic Frameworks (MOFs) are materials that contain metal centers coordinated by organic molecules that form an extended, porous lattice. These MOFs are of interest in the field of sensing for their unique properties such as high stability, high surface area, high crystallinity, and ability to perform small molecule exchange. Luminescent metal-organic frameworks (LMOFs) are of specific interest since they contain the potential to detect volatile organic compounds via adsorption into the porous framework. 1 Luminescent properties can be imparted to MOFs in several ways. Previous projects focused on the inclusion of the luminescent osmium complex Os(dcphen)(CO)2 (Cl)2 (dcphen = 1,10-phenanthroline-4,7-dicarboxylic acid) into the lattice of zinc-based MOFs. These systems exhibited luminescence quenching when exposed to alcohols. However, zinc MOFs possess unique challenges when applied to water-based systems since they readily decompose in the presence of water which limits the potential for aqueous sensing. The goal of this project is to develop a LMOF that is stable in aqueous environments. MOFs composed of zirconium carboxylates exhibit fascinating properties such as high thermal stability and superior chemical resistance towards several solvents due to strong Zr-O bonds and high coordination number between the Zr clusters and organic ligands. The methodology in which these zirconium LMOFs are synthesized and the photophysical properties of the LMOFs in the presence of polar and nonpolar guest molecules will be detailed. The zirconium-based LMOFs proved to be stable in aqueous environments and will be further studied for sensing of analytes in the presence of water
eTherapy app Phase 2
Full text linkThe eTherapy app Phase 2 development cycle transformed the app to its next version. The app was designed to read motion sensor data to assist in Occupational Therapy and with phase 2, the app has been changed based on the feedback of prior testers. Phase 2 expanded upon the data storage and motion reading capabilities of the app. The landmark achievement of Phase 2 is the introduction of custom exercises where the therapist can store readings of their patient\u27s motion data to make custom exercises which the patient can repeat
Impact of COVID-19 on the Energy Sector – A Comparative Study of the US and UK
Full text linkCOVID has affected all of us in many ways. For many, quality of life has changed since the spring of 2020 due to the significant shifts in one of the most crucial resources in today’s society, i.e. the energy. According to the U.S. Energy Information Association, United States’ energy production exceeded consumption in 2019 for the first time since 1957. One year later, residential demand increased by about 20% (Marohl, 2020).
Since the energy sector is extremely broad, this study intends to focus on a subset of the major shifts during the pandemic for specific industries of the sector. Specifically, we study four industries: natural gas, integrated oil, coal, and alternative power generation. A list of the top ten companies in each industry, both public and private based on revenues, is compiled using data from the FactSet and Bloomberg terminal. Additionally, the performance measures of each company include market prices, return on assets (ROA), and the return on equity (ROE) of the company over the past five years. Important news connected to firm-specific changes, energydemand shifts, and ongoing-war conflicts provides insight towards the future of the Energy Sector internationally.
The change in demand for energy strongly depends on each country. Consequently, this study seeks to include U.K. market information to expand beyond the U.S. market changes within the past five years. This study will offer key insights and implications on how pandemics would impact countries’ economies; most importantly how to prepare for the future.
In the meantime, we recognize that Covid is an extremely complex and expansive factor to the world economy, and its impact does not account for all shifts witnessed over the past five years
SWOT Analysis of Entrepreneurial Occupational Therapy in Community-Based Practice
Full text linkThe literature suggests that community practice in occupational therapy (OT) is a beneficial and cost-effective way to expand occupational therapy services past traditional practice into emerging practice areas that meet the direct needs of the clients. Through entrepreneurship in the field, occupational therapists can expand the scope of occupational therapy practice. The purpose of this scholarship project is to increase widespread understanding of the benefits, feasibility, and challenges of entrepreneurially establishing community-based occupational therapy practice. Four occupational therapists who practice occupational therapy in a community-based setting whose practice is also entrepreneurial in nature were interviewed, and their responses were assimilated into a SWOT analysis. Based on the information collected in the SWOT analysis, it is clear that occupational therapy has a viable opportunity to expand further into communitybased practice through entrepreneurship to provide meaningful and needed services to individuals and populations. AOTA, OT schools, and other governing bodies need to support both students and practitioners interested in and currently working in entrepreneurial community-based settings to make this expansion
Risky Business: Measuring the Impact of Introversion, Extraversion, and Risk Aversion on Individual and Joint Decision Making
Full text linkDecision making is a rich field of study explored across multiple disciplines in a variety of settings. One specific area that has received a great deal of attention is financial decision making, most notably Kahneman and Tversky’s (1979) work on psychological patterns affecting risk aversion in individuals. There are, however, areas yet unexplored, including the role of personality, group composition, as well as emotion regulation. This study seeks to explore these concepts. To accomplish this, an experimental approach was utilized to test risk aversion levels of individuals and partners in their financial decision making. Introversion, extraversion, emotion regulation, anger, and stress, were also accounted for. Overall, results were mixed but did demonstrate promise that emotion regulation, anger, introversion and extraversion were factors in financial decision making
Writing Priorities across Academic Disciplines
Full text linkThis project examines the writing priorities of varied disciplines at Elizabethtown College to better understand what they value in student writing. A survey sent to faculty collected discipline-specific writing concerns and information about writing requirements beyond foundational courses. It also gathered thoughts on how EN100, Etown’s introductory English composition course, supports or fails upper-level writing. Follow-up interviews were conducted with select faculty. Faculty responded that sentence mechanics errors, paragraphs that lack unity or feel disorganized, failure to find effective sources when needed, and lack of clarity at the word or sentence level were the most problematic common writing errors when seen repeatedly in upper-level students’ writing assignments. These issues are addressed in EN100, which shows the introductory course is giving students the tools to write effectively, but the skills are not transferring to disciplinary writing. To better facilitate the transfer of writing skills from EN100 to the varied disciplines, non-English instructors can create departmental vertical writing programs, incorporate library research guides, develop a more effective partnership with the Writing Wing, base their instruction on writing studies, and give additional support for grammar and mechanics development. Recommendations for EN100 and FYS instructors and the Senior Leadership Team are also provided
Interoception Awareness and Intuitive Eating
Full text linkCollege is a time where students are required to nourish themselves independently. Weight loss and weight maintenance can be difficult for many, as students are more likely to turn to external methods to lose weight, which are not successful and sustainable long term. Students may be more likely to turn to external mechanisms to lose weight because the have poor interoception awareness, which is the ability to make meaning and sense of hunger and fullness cues. This study aims to discover if interoception awareness is a requirement for intuitive eating, which is an eating approach that uses the body as a guide to make food choices
