- Description:
- The research suggests that seating arrangements in the classroom shape students’ learning experiences. However, the emphasis in most classrooms seems to be placed in behavior management rather than actual learning. This study investigated how classroom seating arrangements shape middle school students’ experiences in the classroom and focused on two questions: (1) How do students perceive the ways that seating arrangements shape their learning experiences in my classroom?; (2) In what way does in-class behavior suggest that seating influences student learning? Through the use of a student survey, student focus groups, and classroom observations, I found that students believe they learn best when seating arrangements provide peer support and access to resources, and that students believe they do their best learning when they are seated in table groups or working independently. The implications of this study include that the nature of the task should dictate the student seating arrangement.

- Description:
- Students identified with emotional disturbance (ED) have emotional and behavioral needs that impact their ability to be successful in various settings. Many of these students display immature social skills and have difficulty forming relationships. Many also struggle in the general education environment and require a more restrictive setting to progress academically and behaviorally. The purpose of this mixed design study is to explore the effects of social skills instruction on the behavioral growth of students identified with ED in a nonpublic school setting. Although still considered to be limited, research has indicated that implementation of social skills instruction, character education, and lessons that promote classroom communities have a positive effect on classroom performance. This study and the curriculum developed for the study provide a starting point for teachers looking to implement social skills training within their classroom settings. Six social skill lessons in specific areas; working collaboratively, communicating effectively, accepting differences, decision making, communication and managing anger were utilized. Although significant behavioral growth was not indicated as a result of the study, researcher observations noted that social interaction, collaboration, student engagement, and concept attainment was evident.

- Description:
- The optimization of lossy compression of images is inherently difficult due to the complexity of human visual perception. Existing optimization techniques perform adequately, but often stop at local optimal points in the search space of compression solutions. Evolutionary programming is an alternative to human-designed algorithms that has been applied successfully to overcome local optima in machine learning applications. Evolutionary programming borrows from nature the concepts of survival-of-the-fittest and the crossover of genetic material between individuals in a population to produce a new generation of individuals. The result is a guided search through the solution space for a problem. Genetic algorithms (GA) and genetic programming (GP) are two types of evolutionary programming. GA has been applied to many applications including vector quantization (VQ) compression codebook generation. GP is an extension of genetic algorithms in which the individuals in the evolving population are represented by hierarchically structured program trees instead of fixed length strings of characters. GP has been applied in various fields such as analog circuit design with results that rival human designed solutions to the same problems. No previous research has been found that applies GP to the problem of VQ codebook generation. Co-evolution is an extension of GP in which a population of problems to be solved evolves at the same time as the solution population evolves. Co-evolution has been shown to perform better than normal evolution at overcoming local optima for some applications. This research examines a novel use of genetic programming and coevolutionary genetic programming for the evolution and co-evolution of VQ codebooks for image compression. The results show that codebooks generated using traditional human-coded compression algorithms can be further optimized with the use of GP and co-evolutionary GP.

5. Yo lo he mirado, yo lo he vivido: The Sexual and Reproductive Health of Three Generations of Latinas
- Creator:
- Avila, Daisy
- Description:
- This study focuses on the lived sexual and reproductive health experiences of four families, each with three generations of Latinas living in the Eastern Coachella Valley. Existing literature has portrayed Latinx communities through a deficit lens, where their culture, language and healing practices are coded as barriers. Chicana Feminist Epistemology (CFE) was foundational in placing the testimonios and platicas of Latina daughters, mother and granddaughters at the forefront of knowledge production and publication. A Public Health Critical Race (PHCR) praxis was the lens through which I contextualized the everyday health realities of Latinas navigating medicalized systems within the United States. Through twelve semi-structured interviews, one of which is my own, we communicate the ways in which our upbringings influence the women we are today. Findings of this study highlight the current obstacles we navigate in medical and educational institutions situated within a rural region, the intergenerational wisdom and remedios that shape our cultural capital and healthcare advocacy, and the narratives of resilience that we share amongst generations of mujeres.

- Description:
- The Efficient Market Hypothesis (EMH) says that there is no better forecast of stock price possible. If one believes in the EMH, then the stock price movements should follow a random walk. Stock price changes should be random and unpredictable. Despite this hypothesis, we decided to build three back-propagation neural networks and three recurrent neural networks to forecast the daily closing price of stock indexes (S&P500, Dow Jones, and NASDAQ). Our experiments showed that the price is predictable and much better than the random guess. Using a simple shortterm investment strategy, a good annual profit rate can be obtained. Different activation functions and different data preprocessing techniques were tested in order to dynamically determine the best neural network topology. We explored more than six hundred network structures for each neural network in our experiments. The same data sets were also analyzed by statistical models using a commercial statistics package. We find that the parameters of the statistical models can help us in determining the recurrent neural network structure. Comparing the forecasting results, our recurrent neural networks outperform the statistical models in terms of the annual profit rates.

- Teachers often use silent reading to help students practice independent reading skills to build comprehension and improve reading proficiency. The purpose of this study was to explore how the classroom environment and its factors shaped my second grade students' engagement during silent reading time. I asked: (1) How are the students in my classroom experiencing silent reading time?; (2) What classroom environmental factors are shaping students' silent reading experiences in the classroom? Through surveys, interviews, video-recordings of silent reading time, and document collection, I learned that students of varying proficiency levels enjoy silent reading time and find it important to their daily schedule. Data also suggested that they enjoyed this silent reading time when in a comfortable and quiet environment. Implications include opportunities for teachers to structure the classroom environment for optimal silent reading.

- Company X focuses on providing support and training for individuals with developmental disabilities. The overall cybersecurity posture of the organization does not rank high on their funding priority list. As a rule of thumb, an organization should spend between 7% and 10% of its IT budget on security (Violino, 2019). Company X requires a considerable amount of Personally Identifiable Information (PII) to perform their services. This includes: parents’ address, clients’ Social Security Number, State Identification Number, medical insurance number, medical history, and bank account numbers. Clearly, this is a substantial amount of sensitive information. Such PII should and must be protected by HIPAA law. The cybersecurity resource burden falls hard on nonprofit organizations and cybercriminals have discovered the gold mine that is nonprofit data (Nimishakavi, 2017). Although cybercriminals are equally likely to target nonprofits and major companies, nonprofits struggle to meet the expense of providing adequate protection for the data they collect. In 2019, The Internet Crime Complaint Center (IC3) received a total of 467,361 complaints with reported losses exceeding $3.5 billion. The most prevalent crime types reported were Phishing/ Vishing/ Smishing/ Pharming, Non-Payment/Non-Delivery, Extortion, and Personal Data Breach (Gorham, 2019). What makes the issues more troubling is the fact that a considerable amount of that information can be stored on the managers’ and employees’ personal laptops and cell phone. This can increase the risk of a cyber-related events occurring. With that in mind, the purpose of this project is to create a security plan for Company X to protect such confidential information.

- Description:
- Most modern research labs utilize liquid chromatography-tandem mass spectrometry, or LC-MS/MS, to analyze mixtures in both qualitative and quantitative capacities. This makes it imperative to teach students how to operate and understand these instruments even at an undergraduate level. The final goal of this project was to develop a method to use in an academic setting to demonstrate the versatility of LC-MS/MS. The protocol takes advantage of the low detection limit when needed, while using less sensitive methods with samples containing higher amounts of analytes. There are multiple methods used to run samples including Scan for broad range data at high concentrations and multiple reaction monitoring (MRM) for highly specific low concentration analysis. The dynamic range of the instrument was shown from 1 pg/mL to 1 mg/mL when run in the various available modes. The two compounds utilized in this study to demonstrate the unique abilities of this instrument are caffeine and theobromine. These are most commonly known as the stimulants in coffee and cocoa respectively. These natural products are ideal for exhibiting the power of this instrument because they are homologous compounds that differ by a single methyl group and have very similar polarity and spectroscopic characteristics. This makes it difficult to achieve rapid baseline separation using many instruments commonly found in a chemistry laboratory, but they can be individually integrated even without baseline separation using the MRM method. The high matrix nature of the food samples was overcome with the specificity of the method without extensive sample preparation. A rinse method that cycled between high and low organic mobile phase was shown to effectively elute residual compounds from the column. A lab protocol and instrumental instruction set were established for the Agilent 6410 triple quad system.
