A Novel Analysis of the Redshift Dependence of the Masses of the Supermassive Black Holes of a Sample of Quasars
No full textA type of active galactic nucleus is the quasar, or quasi-stellar radio source. Quasars are integral to understanding the formation and evolution of galaxies. This research was conducted by utilizing data from Grier, C. J. et al. 2019 and the Sloan Digital Sky Survey and leveraging a suite of analytical methods. The research focus of this paper was to determine the nature of the quantitative relationship between the redshift of a sample of quasars and the masses of the supermassive black holes of these quasars and thereby determine how a quasar\u27s supermassive black hole mass evolves as the quasar ages over time. The hypothesis of the paper was that there will be an identifiable quantitative relationship between quasar redshift and quasar supermassive black hole mass. With a correlation coefficient of approximately 0.27, the quantitative relationship between the two variables was weak but positive. However, the quantitative relationship between quasar redshift and quasar supermassive black hole mass was statistically significant with a p-value of approximately 0.000008. Because of how there was a roughly linear relationship between these two variables, linear regression as opposed to non-linear regression was run. Only about 7% of the variation in quasar supermassive black hole mass could be explained by quasar redshift
EXPLORING SUSTAINABLE BIOPOLYESTERS: SYNTHESIS FROM 1,4-BUTANEDIOL AND ALIPHATIC DIACIDS
Get PDFIn this thesis, we applied 1,4-butanediol, which is an emerging biobased and low-cost monomer, was synthesized with a series of aliphatic dicarboxylic acids, namely succinic acid, adipic acid, and sebacic acid using melt polycondensation to Biobased polyesters. The resulting polymers poly(butylene succinate) (PPeS), poly(butylene adipate) (PPeA), and poly(butylene sebacate) (PPeSe) chemical structures were analysis through Fourier transfer infrared spectroscopy(FT-IR), 1H nuclear magnetic resonance (NMR) revealed the elimination of side reactions in the obtained polyesters. Differential scanning calorimetry (DSC) was employed to analyze physical properties, and the impact of dicarboxylate chain length and long short diol on crystalline structure and thermo-mechanical properties was investigated characterized with intrinsic viscosity, nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), dynamic mechanical analysis(DMA) and tensile testing. All the polymers had weight-average molecular weight over 50,000 g/mol and melting temperature (Tm) ranging from 50˚C to 116˚C, PPeA exhibited a lower melting temperature due to semicrystalline structure and rapid crystallization. The “even-even” effect was observed, contributing to increased tensile strength of PPeA. All the polymers exhibit good thermal stability, mechanical properties and tensile properties compared to polyethylene. These biobased and potentially biodegradable polyester appear to be promising for practical applications like packaging, biomedical materials, and environmentally friendly plastics
Incremental Rehearsal as an Instructional Technique for Young Children with Autism Spectrum Disorder
Get PDFRepetition is said to be the most important factor in learning (Symonds & Chase, 1992). A common instructional technique that also incorporates repetition is incremental rehearsal (IR), which is often implemented due to its potential efficiency and effectiveness. Previous research has indicated a positive effect on reading fluency, math intervention, and sight word acquisitions using IR teaching procedures; however, there is a stark lack of application of IR to individuals with autism spectrum disorder (ASD). Therefore, the purpose of the study was to evaluate IR as an instructional technique for skill acquisition, specifically within an early intervention setting with young children with ASD. The study used a concurrent multiple baseline design across participants to evaluate rate of skill acquisition and trials to criterion for target mastery with the implementation of IR procedures. Three participants were taught to vocally identify varied stimuli (e.g., flags, safety signs) through a modified IR procedure that used repetition and interspersed trials. Results suggest that incremental rehearsal is an effective intervention strategy for promoting skill acquisition in children with ASD
IMPROVEMENT OF NATURAL ENVIRONMENT TEACHING USING BEHAVIORAL SKILLS TRAINING
Get PDFAutism spectrum disorder (ASD) affects individuals through persistent deficits in social communication and excesses in restricted and/or repetitive behaviors (American Psychiatric Association, 2013). Applied behavior analysis (ABA) is the only evidence-based treatment for ASD and uses behavioral and learning principles to shape behavior change (Ferguson et al., 2022; Lax et al., 2023; National Autism Center, 2015). ABA has many teaching methods, one being discrete trial training (DTT; Smith, 2001). DTT is a highly structured method of teaching in which the instructor provides clear instructions, the learner responds in some way, and then the instructor gives a consequence for the response (Smith, 2001). Despite efficacy, DTT has been criticized for being highly structured and failing to promote student generalization (Smith, 2001). In contrast, natural environment teaching (NET) directly programs for generalization by incorporating a variety of stimulus formats, settings, and people (Sundberg & Partington, 2013); however, the fluid nature of NET gives more opportunities for mistakes in implementation (Granpeesheh et al., 2009; Sundberg & Partington, 2013). The purpose of the present study was to evaluate the impact of Behavior Skills Training (BST) on implementation fidelity during NET-style instruction in practitioners working with children in a preschool setting. Three preschool staff who completed intervention increased their percent accuracy from an average of 53% in baseline to an average of 92% in a naturalistic environment reaching mastery criteria, with one staff maintaining this increase over time. This data suggests that BST is an effective training to improve percent accuracy for NET Implementation
A Graduate Recital in Conducting
Get PDFThis graduate thesis consists of a choral conducting recital and the accompanying program notes. The recital features music from a variety of styles, cultures, and time periods. The program includes works by Marc-Antoine Charpentier, Robert Schumann, Johannes Brahms, Hyo-Won Woo, Jean Sibelius, Samuel Sebastian Wesley, Charles Villiers Stanford, Christian Onyeji, and Sydney Guillaume. The program notes for each piece include composer information, musical analysis, historical and cultural background, and performance considerations. This recital reflects the conductor’s musical journey at Pittsburg State University and highlights the beauty of diverse choral music through collaboration and shared musical experience
