Unpacking Algebra: 98 Lessons with Applications
No full textMiddle and high school students have difficulty learning algebra partly because they don’t see the connections between algebra concepts and future applications. Without seeing why they should care, they lack the motivation to persevere when the work gets challenging. We used several sources, including visits to local classrooms, to compile a list of requisite pre-algebra and algebra skills. With those in mind, we devised lesson plans that introduce and practice one or more of the target skills and include applications whenever possible. We created 98 such lesson plans, cross-listed by algebra skills used. In pairs, we taught at Northfield Middle School, allowing us to assess the effectiveness of our work. These lessons will be compiled to form a textbook that will be made available to middle and high school teachers
The Quality of Life from Being Pro-Life: Analyzing the Impact of the Overturning of Roe v. Wade on the Economic Lives of Black Women
No full textOn June 24, 2022, the United States Supreme Court voted to uphold Mississippi’s Gestational Age Act, which banned abortions after fifteen weeks and overruled Roe v. Wade, a decision made in 1973 which gave women the constitutional right to an abortion. While this change in precedent affected all women in the United States, it will particularly impact Black women compared to white women and all men. In terms of fertility, Black women get more abortions and get more abortions per capita than white women. (Reported Legal Abortions by Race of Women Who Obtained Abortion by the State of Occurrence, 2022) In terms of labor supply, Black women are more likely to be a part of a low-income household than white women. (What Are the Implications of the Overturning of Roe V. Wade for Racial Disparities?, 2022) This income disparity manifests itself as Black women having less access to emergency funds in unexpected circumstances. (What Are the Implications of the Overturning of Roe V. Wade for Racial Disparities?, 2022) Barriers created by lack of abortion access, compounded with those already faced by women in the labor market, will both reduce the number of women in the labor force and disincentivize women from investing in human capital to join the labor force at all, leading to an overall decline in the quality of life for Black women compared to men in the United States. My proposed solution, more comprehensive sexual education in schools across the United States, more accessible contraceptives in Black communities, and less expensive birth control procedures, will go a long way towards solving the problem at its source as opposed to simply treating the symptoms
Quantum Mechanical Treatment of Spin-1/2 Nuclear Magnetic Resonance Spectroscopy
No full textEvery undergraduate chemist performs NMR for structural characterization, but we tend to overlook the phenomena from which NMR spectra arise. Working within the framework of quantum mechanics and incorporating ideas from classical electromagnetism, I discuss a few of the key physical concepts underpinning NMR spectroscopy
The Importance of F. prausnitzii and Butyrate Production in the Development of Inflammatory Bowel Disease
No full textEfficacy of Virtual Reality Exposure Therapy as Treatment for Children with Social Anxiety Disorder
No full textThe COVID-19 pandemic has exacerbated symptoms for children with social anxiety disorder and has triggered the onset of social anxiety disorder for others. The COVID-19 pandemic also has increased the need for therapies and treatments that help children with social anxiety disorder adjust to the new social situations and interactions brought on by the pandemic in a safe and accessible environment. Virtual reality exposure therapy (VRET) is becoming a popular treatment for anxiety disorders because it creates a controlled, safe environment for patients and can be more accessible than other treatments, especially during the COVID-19 pandemic. Present research has shown that VRET for individuals with social anxiety disorder can be effective, as well as cost and time efficient. However, more research is needed on the use of VRET for children with social anxiety disorder and on which uses of this treatment are most effective for this specific population. Combining present research and literature on childhood social anxiety disorder, the impact of COVID-19 on social interactions, and the efficacy of VRET, I analyze the current and potential efficacy of virtual reality exposure therapy for childhood social anxiety disorder and conclude that VRET has the potential to treat children with social anxiety disorder during the COVID-19 pandemic and in other similar situations
Has Swiping Become Too Casual? Relationship Between Dating App Usage & High-Risk Behaviors
No full textMobile dating applications are not new phenomena and have improved and increased in use over recent years (Curry, 2023). Due to social isolation from COVID-19 over the last 3 years, humans have been forced to utilize devices to be social and to meet people. The aim of this paper is to examine how periods of change in adolescence and early signs of risky behaviors during adolescence are, in part, responsible for the risky sexual behaviors young adults display online. Early risk behaviors arise from coercion from peers and this coercion can happen online to young adult dating app users. Social evaluation and sensation seeking are factors in adolescence and are expressed in online behavior. Risky sexual behaviors (RSBs) are actions that put oneself and others at risk like sexual coercion, STI/HIV contraction, and sexual pervasiveness. This review finds that early risk behaviors correlate with the likelihood of performing other problematic behaviors online. Future implementation steps to reduce risk from coercion, social evaluation and sensation seeking include contraception access and user verification to make online meetings safer
AIDS, Affect, and Alternative Realities: Paranoid and Reparative Readings of Thom Gunn’s The Man With Night Sweats”
No full textAs both a constant reminder of the disease-inflicted body and the celebration of queerness and queer communities, AIDS literature generates a wide affective spectrum. In The Man with Night Sweats, Thom Gunn explores this spectrum through a poetic process of (dis)embodiment that creates a web of relationships marked by negative (pain, grief) and positive (joy, love) feeling. On the one hand, Gunn’s work calls for what Eve Kosofsky Sedgwick calls “paranoid reading”: an anticipation of and emphasis on AIDS’ ravaging of the body to reestablish poetry in its real world social/political context. On the other hand, Sedgwick’s reparative reading, which searches for pleasure rather than warding off pain, is imperative to the queer world-building Gunn achieves in conjunction with his corporeal recognition. In this paper I suggest a simultaneous application of paranoid and reparative strategies in reading The Man with Night Sweats. I argue that this simultaneous reading accounts for the agency of marginalized bodies while also acknowledging the shared spaces constructed for those bodies—spaces that persist with and without the diseased body
Graphs with Many Hamiltonian Paths
No full textA graph is hamiltonian-connected if every pair of vertices can be connected by a hamiltonian path, and it is hamiltonian if it contains a hamiltonian cycle. Every hamiltonian-connected graph is hamiltonian. However we construct families of non-hamiltonian graphs with `many\u27 hamiltonian paths, where `many\u27 is interpreted with respect to the number of pairs of vertices connected by hamiltonian paths. We then consider minimal graphs that are hamiltonian-connected. It is known that any order-n graph that is hamiltonian-connected graphs must have\u3e=3n/2 edges. We construct an infinite family of graphs realizing this minimum
