Strengthening of Continuous Reinforced Concrete Deep Beams with Large Openings Using CFRP Strips
No full textTo accommodate utilities in buildings, different sizes of openings are provided in the web of reinforced concrete deep beams, which cause reductions in the beam strength and stiffness. This paper aims to investigate experimentally and numerically the effectiveness of using carbon fiber reinforced polymer (CFRP) strips, as a strengthening technique, to externally strengthen reinforced concrete continuous deep beams (RCCDBs) with large openings. The experimental work included testing three RCCDBs under five-point bending. A reference specimen was prepared without openings to explore the reductions in strength and stiffness after providing large openings. Openings were created symmetrically at the center of spans of the other specimens to represent 40% of the overall beam depth. Moreover, finite elements (FE) analysis was validated using the experimental results to conduct a parametric study on RCCDBs strengthened with CFRP strips. The results confirmed reductions in the ultimate load by 21% and 7% for the un-strengthened and strengthened specimens, respectively, due to the large openings. Although the large openings caused reductions in capacities, the CFRP strips limited the deterioration by enhancing the specimen capacity by 17% relative to the un-strengthened one
Quantifying the Structure of Residential Water Demand in the United States: a Generalized Exact Affine Stone Index Demand Framework
No full textWe utilize a Generalized Exact Affine Stone Index system to evaluate the structure of residential water demand that recognizes demand interrelationship between residential and bottled water in the United States, allowing for precommitted consumption. Further, we address expenditure and price endogeneity by accounting for the supply side of the price determination mechanism. A significant substitutability relationship between residential and bottled water is found, while substantial precommitments are established in both residential and bottled water consumption. Residential demand becomes price-elastic once the precommitted level is reached. Finally, ignoring substitutability, precommitments, or endogeneity distorts the demand structure, resulting in erroneous policy implications
The Efficacy of Online Eye Movement Desensitization and Reprocessing (EMDR)-Informed Therapy for Clients with Post Traumatic Stress Disorder (PTSD) Symptoms
No full textThe effects of EMDR-informed therapy via an online platform for individuals with PTSD symptoms was examined using a single case multiple baselines across participant design. The study sessions were “EMDR-informed,” meaning they were patterned after elements of the basic EMDR protocol established by founder Francine Shapiro (Shapiro, 1989, 2017) but were not proven to meet the standards of EMDR therapy based on the EFSR (EMDR Fidelity Rating Scale; EMDR Foundation, n. d.). The sessions in this study did not meet those requirements and therefore cannot be represented as EMDR therapy; however, many of the interventions in the sessions were inspired by EMDR therapy and therefore “EMDR-informed.”Adult individuals who met criteria for a DSM-5 Criterion A trauma (exposure to actual or threatened death, serious injury, or sexual violence) and who were currently experiencing PTSD symptoms (intrusion, avoidance, negative mood or cognitions, alterations in arousal/reactivity) were invited to participate in the study. Posttraumatic Stress Disorder Checklist (PCL-5) was used weekly to establish baseline functioning during A phase as well as treatment response during B phase. Each participant was interviewed by the researcher at the beginning and end of the study using the Clinician-Administered PTSD Scale for DSM-5, Past Week Version (CAPS-5). Data were analyzed using level, trend, variability, overlap, immediacy, and consistency. Percentage of Non-Overlapping Data (PND), and Percentage Exceeding the Mean (PEM), were used to analyze overlap and consistency. Results differed between the two effect size measures. Using PND, there were no treatment effects. Using PEM, three participants experienced large treatment effects and one experienced a small treatment effect. When comparing the percentage of score decrease from pre/post CAPS-5 scores all participants experienced a decrease in PTSD symptoms and therefore some level of treatment effectiveness. Three of the five participants strongly confirmed the social validity of EMDR-informed therapy via TMH. Limitations, suggestions for future research, clinical implications, and conclusions are presented

Conformity of Scripts: Mortality Salience and Sexual Scripts
No full textThe present dissertation aimed to explore the relationship between terror management theory (TMT; Greenberg et al., 1990) and sexual script theory (Gagnon & Simon, 1973) in a sample of heterosexual adults. The goal of this study was to developed a new avenue of inquiry of human sexuality for TMT when accounting for the fundamentals of sexual script theory, namely the relationship between cultural, interpersonal, and intrapsychic scripts of sexuality, and the cultural, temporal, and gendered foundations of sexual behavior. To test this, heterosexual men and women were engaged in a mortality salience manipulation prior to recording their sexual scripts (Bowleg et al., 2015; Brooks, 2019). The hypotheses were not confirmed in the, as mortality salience did not seem to affect the sexual script. The present study demonstrated the weaknesses of both sexual script theory and TMT, as well as emphasized the importance of intentional participant recruitment methods
