How to Maximize Your Return by Investing in the Pharmaceutical and Natural Resource Industries
Full text linkIn this paper, we will be discussing the five-year performance of five stocks that include two different sectors: natural resources and the pharmaceutical sector. We chose these sectors because of the positive returns on their stock prices that have been shown since Covid, as well as the fact that pharmaceutical companies are frequently creating new medicine and natural resources. The performance of these five stocks will be evaluated through R-studio using various financial models, including Portfolio Theory, the Capital Asset Pricing Model, and Factor Model. We will first employ an investment strategy that is contingent upon maximizing return and by choosing a variation of risky and stable stocks. By using a strategy as such, we will be able to hedge some of the systematic risk present with investing into a singular stock. However, a model may predict how much of the original investment to allocate into each of the stocks in order to achieve our goal of maximizing return. While looking at the weights and the historical return averages for each of these stocks, an expected return can be calculated to determine which to invest in. We will compare the portfolio ROIs at the end of the holding periods to determine which model has given us the most beneficial return. Upon completion of carrying out these models, we can then compare which ones allowed for us to receive the most return, and what could have been done to prevent potential loss.Huarui Jin
The Search for Common Ground: Howard Thurman's Theological Vision and the Post-Pandemic Episcopal Church
No full textFor decades, The Episcopal Church has been experiencing seismic change. In many 'ways, the COVID-19 pandemic intensified and accelerated trends already long underway, while also laying bare the social divisions of race and wealth that mark our nation and our world. How our society reorders itself in the wake of the pandemic is not morally or theologically neutral. The stakes are high, and so is the call for faithful witness and moral leadership. The Episcopal Church is called today to cast a theological vision that frames the fundamental questions of our time: who are we meant to be — as people, as a nation, and as a world? What does collective human flourishing look like? How do we move forward together to achieve it?
Howard Thurman devoted his life to seeking the thread of the eternal God that bound together humanity and could lead to common ground. The upheavals of war, pandemic, white supremacy, and social change marked his time as they do our own. This thesis aims to sketch the history and trends that shape our nation and The Episcopal Church in 2023. It then considers Howard Thurman's life, context, and creation theology in his mature work The Search for Common Ground as sources of wisdom for our own quest for common ground in today's divided world. Finally, it adapts Howard Thurman' s creation theology as a framework for theological reflection on the experience of the pandemic, considering the theological vision The Episcopal Church is called to proclaim and embody today.Robert MacSwai
Synthesis, Purification, and Characterization of Mercaptosuccinic Acid-Carbon Quantum Dots
Full text linkCarbon quantum dots (CQDs) are carbon-based nanoparticles that are typically synthesized from citric acid (primary carbon source). In our research, we use alternative carbon sources, namely water-soluble thiols and polycarboxylic acids. For this project, mercaptosuccinic acid (MSA) and ethylenediaminetetraacetic acid (EDTA) were used as the primary carbon sources. After their synthesis in a conventional microwave, these CQDs were thoroughly purified through centrifugation, fluorescent flash chromatography, and dialysis. Fluorescent flash chromatography displayed three distinguished fractions of our MSA-CQD samples: yellow, green, and blue in color. The purified CQDs were then analyzed using UV-visible and fluorescence spectroscopy to observe their structural and functional properties. The analysis of these nanomaterials determined their stability which can be applicable for their use as future biological and chemical sensors. Heavy metal ion sensing was performed, with fluorescent quenching observed with the addition of this metal ion. CQD samples were pH adjusted in a phosphate buffer, and it was noted that the emission wavelength and intensity of fluorescence was stable in, and well beyond, the physiological pH range. The quantum yield of the MSA-CQD fractions was also analyzed.Chemistry Department at the University of the Sout

A plasmid-launched reverse genetics system for the human coronavirus HCoV-OC43
Full text linkCoronaviruses (CoVs) are a large family of single-stranded, positive-sense RNA viruses that infect a wide range of vertebrate hosts. Along with SARS-CoV-2, the etiological agent of the COVID-19 pandemic, there are six other characterized human CoVs (HCoVs). Infection by the four endemic HCoVs (e.g., -OC43, -NL63, -229E, -HKU1) are often associated with the common cold, while infection with epidemic HCoVs (e.g., SARS-CoV and MERS-CoV) can result in severe disease with high mortality. HCoV-OC43 is an attractive model for studying HCoV replication, as it is related to both epidemic and pandemic HCoVs but generally causes only cold-like illness. However, the use of HCoV-OC43 as a model system to study HCoVs is complicated by the lack of reagent availability, in particular robust genetics systems. We recently established a system to generate recombinant viruses for the murine coronavirus mouse hepatitis virus, strain A59 (MHV-A59). Using this technical knowledge, a similar yeast-derived transformation-associated recombination (TAR) system was generated for HCoV-OC43. Using commercially available purified HCoV-OC43, we used reverse transcription (RT) to generate overlapping viral dsDNA genomic fragments. All fragments were assembled in the correct order and the resultant full-length dsDNA genome was synthesized without RT-generated mutations. Following transfection of the assembled plasmid, both viral cytopathic effect and RT-PCR on purified viral RNA indicate that HCoV-OC43 was recovered successfully. Development of this tractable system will enable many mechanistic studies regarding HCoV-OC43 replication which will enhance our understanding of CoV biology.Henrietta Brown Croom Faculty-Student Research Awar

Attachment as a Predictor for Leadership Style
No full textThe relationships of children to their caregivers are known to affect the way people continue to interact and engage with those they are in relationships with later in life. These early relationships can create positive, negative, neutral, or mixed self-maintained concepts of safety and confidence within various kinds of relationships and typically categorize people as secure, anxious, avoidant, or fearful-avoidant. This study aims to explore the connections between child development in terms of attachment theory and how it affects or predicts children’s roles in their communities after childhood, specifically which attachment styles are most likely to connect to which leadership styles, and through correlational research, explain why these connections exist. The study is correlational, and data will be collected using questions adapted from previously-validated attachment and leadership style scales. This study aims to explore the connections between child development and later leadership in terms of attachment theory and how it affects or predicts children’s roles in their communities after childhood
THE WORLD OF SKINCARE AND BEAUTY
Full text linkThe world of skincare and beauty is a creative and diverse space that changes almost every day with new innovations, trends in the market, and technological advancements. With this presentation, we will be looking at the past, present, and future of skincare and beauty. In the past category, we have Jennifer looking at ancient beauty secrets in Peru and Lina looking at USSR makeup products. In the present category, we have Elizabeth looking at the wave of Korean skincare and Chama looking at the emergence of skincare companies created for people of color. In the future category, we have Hannah and Leila looking at the future of parabens in the United States.
Jennifer has researched ancient beauty ingredients in Peru, such as coca leaves, quinoa, and maras salt. Coca leaves are used to firm the skin and reduce cellulite, quinoa is used for face masks and balms, and maras salt is used as a body scrub and for healing the skin. Lina has researched USSR makeup products, and how products like eyebrow mascara "Leningrad", face foundation "Ballet", perfume "Red Moscow", and eyeshadow "Elena" were essential beauty products in everyday usage of women. She has also found how those products were a part of the political agenda in the times of the Soviet Union.
Elizabeth has researched the wave of Korean skincare and makeup products, also known as “K-Beauty”. South Korea is the capital of skincare, and its innovative products such as BB creams and snail mucin have become popular all over the world. Chama has researched the emergence of POC skincare companies. POC owned beauty companies have worked to reclaim cultural practices around skincare from the white dominated beauty industry.
Leila and Hannah have researched the use and future of parabens in the US. Since the 1920s, the use of parabens, artificial preservatives, began becoming widely used in the United States, but recent studies saw an association between parabens and breast cancer, and more. Trends have emerged to stop buying all products with parabens, but the US still needs to take action and create a federal standard.Sewanee Cosmetics Club
