A Comparison of Discrete-Trial Techniques on Direct Service Provider Productivity
Get PDFEarly intensive behavioral intervention (EIBI) is one way to remediate social deficits, skill detriments, and problematic behaviors of children diagnosed with ASD (e.g., Cohen et al., 2006; Lovaas, 1987; Smith, 2001; Waters et al., 2020). Effective EIBI includes fast-paced instruction, 35-40 average treatment hours a week, and an early age at the start of intervention (Lovaas, 1981). Positive outcomes of EIBI include fine and gross motor skill acquisition, placement in a typical education classroom, increased language, and decreased problematic behaviors (e.g., Cohen et al., 2006; Lovaas, 1987; Smith, 2001; Waters et al., 2020). One method of EIBI with very little research is the Verbal Card Sort method. The purpose of the study was to compare two discrete trial training methods on service provider instructional intensity, as well as the effect of instructional intensity on skill acquisition in children diagnosed with autism spectrum disorder (ASD). Seven service providers and four children between the ages of 3 and 6 with ASD were recruited from an autism clinic and placed into dyads. A multiple baseline across dyads design was used to evaluate increases in instructional intensity following the implementation of the Verbal Card Sort method. Rate of instructions per hour and cumulative mastered targets were calculated across historical, baseline, and intervention for all dyads. The card sort method was effective at increasing rate of instructions per hour of five out of six dyads (range = 27.00% - 127.00%) and increasing rate of mastered targets for three out of six dyads (range = 4.76% - 39.39%)
Effect of Nitrogen and Phosphorus in Rigid Polyurethane Foams Synthesized from Bio Derived Polyol
Get PDFRigid polyurethane foams (PUFs) are widely used as thermal insulators due to their excellent mechanical properties and low thermal conductivity. However, their dependence on petrochemical-derived polyols and inherent flammability poses environmental and safety challenges. This study investigates the synthesis of bio-based rigid PUFs using canola oil polyol (COP), a sustainable alternative to petrochemical polyols. The research explores the incorporation of nitrogen and phosphorus-based reactive flame retardants, including diethyl phosphate (DEP), melamine (MA), and a novel compound (TDHTPP) synthesized from cyanuric chloride, diethyl phosphate, and vanillin, to enhance both flame retardancy and mechanical properties. Preliminary results demonstrate that PUFs containing 15gm TDHTPP exhibited the lowest weight loss in burning tests, comparable to MA-modified PUFs, indicating superior flame retardancy. Additionally, PUFs with DEP displayed the highest compression strength (~300 kPa), attributed to a more compact cellular structure, enhancing rigidity. Morphological analysis revealed that PUFs with 5gm DEP and 5gm TDHTPP achieved nearly 100% closed-cell content, optimal for thermal insulation applications. This research underscores the potential of bio-based polyols and nitrogen-phosphorus reactive flame retardants in producing environmentally friendly rigid PUFs with improved fire resistance and mechanical performance. The findings contribute to the advancement of sustainable materials, aligning with green chemistry and environmental protection goals
