Promoting Positive Student Development: A Qualitative Case Study of School-Wide Social and Emotional Learning in an Elementary School
Get PDFMany schools have adopted social and emotional learning programs, but few schools have achieved significant impacts on student outcomes because of challenges with implementation quality. Although there is guidance on selecting evidence-based social and emotional learning programs for classroom use, schools need guidance on how best to integrate social and emotional learning in context. This study examines how an elementary school integrated school-wide social and emotional learning into its daily practices, using a qualitative single case study grounded in Bronfenbrenner’s ecological systems theory. The study, which was conducted during an eight-week period, identifies promising practices that could be beneficial for implementing and improving social and emotional learning practices. Data collection includes multiple sources of data, such as observations, document analyses, semi-structured interviews, and focus groups. Drawing upon Stake’s (1995) process for data analysis, the following themes emerge: (1) routines and shared practices, (2) physical environment and classrooms, (3) common language (4) school family, and (5) leadership support for social and emotional learning. The implications of this study support understandings of what integrated school-wide social and emotional learning programming look like in an elementary school context.

Comparison of Switched Reluctance Motor and Double Stator Switched Reluctance Motor
Get PDFThis thesis is concerned with the design and analysis of Switched Reluctance Motor (SRM) and its improved structure Double Stator Switched Reluctance Motor (DSSRM). Three configurations of SRM viz. Inner Stator, Outer stator and Double Stator are designed and simulated in ANSYS Maxwell Suite. Design parameters are chosen by aiming optimum performance of motor after literature review and analytical study of the motor. SRM is not a line start machine, so power converter circuit is required to excite the motor. Without proper switching of current, desired torque is not obtained in SRM. The converter circuit and switching unit is built in Maxwell Circuit Editor Tools. Both magnetostatics and transient analysis is performed to investigate motion torque, torque ripple, normal force and radial force. A good comprehensive comparison of three different types of SRMs based on their torque profile and force densities is presented. Simulation performed verified better performance of DSSRM
“Your love is too thick”: An Analysis of Black Motherhood in Slave Narratives, Neo-Slave Narratives, and Our Contemporary Moment
Get PDFIn this paper, Kait Spong examines alternative practices of mothering that are strategic nature, heavily analyzing Patricia Hill Collins’ concepts of “othermothering” and “preservative love” as applied to Toni Morrison’s 1987 novel, Beloved and Harriet Jacob’s 1861 slave narrative, Incidents in the Life of a Slave Girl. Using literary analysis as a vehicle, Spong then applies these West African notions of motherhood to a modern context by evaluating contemporary social movements such as Black Lives Matter where black mothers have played a prominent role in making public statements against systemic issues such as police brutality, heightened surveillance, and the prison industrial complex
Eye Gaze and Cortisol Levels in Socially Anxious Young Adults During an Interactive Real World Task
Get PDFSocial anxiety is a disorder where people fear social interactions and is associated with physiological changes. Eye tracking studies have shown that people with social anxiety spent more time gazing at emotional faces presented on a computer screen and spent more time gazing at the eye region. There has been limited studies on tracking eye gaze in a real-life setting interacting with another person. We used a wearable eye tracker during a brief one-on-one interview about participants’ challenges faced at work or school. Along with self-report psychological measures about social anxiety and shyness, we also measured participants’ salivary cortisol as a metric for physiological stress. We hypothesized that socially anxious individuals would have higher cortisol levels and spent more time gazing at the face. However, there was no change in cortisol levels before and after the interview. In addition, socially anxious individuals had lower cortisol levels than less anxious people. Furthermore, the time spent fixating on the region of interest (ROI), which was the face, was not correlated with social anxiety, anxiety or shyness. Paradoxically, the more socially anxious participants seem to have had a lower physiological stress response than less socially anxious participants
Prediction of DNA-Binding Proteins and their Binding Sites
Get PDFDNA-binding proteins play an important role in various essential biological processes such as DNA replication, recombination, repair, gene transcription, and expression. The identification of DNA-binding proteins and the residues involved in the contacts is important for understanding the DNA-binding mechanism in proteins. Moreover, it has been reported in the literature that the mutations of some DNA-binding residues on proteins are associated with some diseases. The identification of these proteins and their binding mechanism generally require experimental techniques, which makes large scale study extremely difficult. Thus, the prediction of DNA-binding proteins and their binding sites from sequences alone is one of the most challenging problems in the field of genome annotation. Since the start of the human genome project, many attempts have been made to solve the problem with different approaches, but the accuracy of these methods is still not suitable to do large scale annotation of proteins. Rather than relying solely on the existing machine learning techniques, I sought to combine those using novel “stacking technique” and used the problem-specific architectures to solve the problem with better accuracy than the existing methods. This thesis presents a possible solution to the DNA-binding proteins prediction problem which performs better than the state-of-the-art approaches
Nitrogen Doped Titanium Dioxide in the Photocatalytic Degradation of Methylene Blue
Get PDFTitanium dioxide(TiO2) is a stable, effective and well-known photocatalyst for degradation of pollutants. However, its practical applications are limited due to the need for energy higher than 3.2 eV, or a wavelength lower than 390 nm (high frequency waves, ultraviolet and above) hindering its ability to effectively work in the visible light region (about 400 nm to 700 nm). Nitrogen-doped TiO2 (N-TiO2) has garnered some attention as a photocatalyst as it appears to work even in the visible light region. This could allow the utilization of a larger part of the solar spectrum. This thesis presents the results of photocatalytic degradation of methylene blue (MB) carried out under simulated visible light by using TiO2 and N-TiO2(doped in the lab) to evaluate and compare their efficiencies under similar conditions
A Comparison of Instructional Strategies: Does How You Teach Mathematics Matter?
Get PDFFor most of the twentieth and all the twenty-first century, there has been a great debate over educational reform for teaching mathematics. From these debates have come a critical look at how to properly instruct students so they can actively learn in the classroom, yet still retain the information for use in their later life. These questions are rooted in the larger debate between philosophical and psychological dimensions of human growth and development. Some educators, therefore, believe structuring their instruction around some philosophies such as idealism, realism, pragmatism, or existentialism was the key to success for their students. Others took the psychological approach and featured behaviorist or cognitive ideas in their teaching. Most feel that the approaches to psychology reflect these philosophical and psychological theories. These positions have resulted in the emergence of specific suggested teaching strategies that each proponent believes provide the solutions to the dilemma of how to best educate today’s students. This study examines what effect two different instructional strategies have on student acquisition of mathematical concepts and procedures
Stray Cats
Get PDFThis paper details the making of Stray Cats, a University of New Orleans thesis film. It examines the process of creating the film in three parts. Part one will detail the pre-production, including the conceptualization, writing, and preparation for the project. Part two will cover the production, including the directing, production design, cinematography, and on-set operations. Part three will describe the post-production process, including the editing, color correction, sound design, and musical score. These three components will then be referenced in regards to the theme of the film, and will conclude by analyzing whether or not the final film achieves the initial vision
Mental Health Practitioners Perceptions’ of Presence in a Virtual Reality Therapy Environment for Use for Children Diagnosed with Autism Spectrum Disorder
Get PDFChildren with autism spectrum disorder (ASD) think and understand social contexts primarily from a visual stand point. Feelings of being present in their social environment are a key component to their development (Strickland, Marcus, Mesibov, & Hogan, 1996). A virtual reality environment (VRE) can provide a therapeutic setting for children with ASD to learn social skills (Ehrlich & Munger, 2012). In the present research, a pilot study was used to assess the validity of a Second Life VRE developed by the researcher (Markopoulos, 2016b) by comparing the VRE to a real life film by The National Autistic Society (2016) in the United Kingdom. Feedback from the pilot study was used to make revisions to the VRE. The validated virtual reality therapy environment (VRTE) was used in the main research study. Twenty-eight Louisiana mental health practitioners’ perceptions of the VRTE were assessed using two random order conditions. Condition A required participation in the VRTE twice, first using a laptop computer only and then using the laptop with the new 2016 Oculus Rift head-mounted display (HMD, Oculus VR, LLC, 2016). Condition B required participation in the VRTE twice, first using a laptop with the new 2016 Oculus Rift HMD and then using a Laptop alone. Four out of eight subscales from the Temple Presence Inventory (TPI) (Lombard, Weinstein, & Ditton, 2011) were used to assess practitioners’ perceptions of presence in the VRTE. Results of a repeated-measures MANOVA showed that the order of the conditions were not significantly different. Additionally, participants’ TPI total and subscales scores were significantly higher when using the HMD than when using the Laptop, as well as their likelihood of using the HMD with children diagnosed with ASD than using the Laptop. All of the correlations for participants’ age and experience with technology were insignificant except for the subscale III, engagement was significant for participants’ age.
