Purpose: It has been reported that adversarial growth during traumatic events potentially enhances coping with sequelae. The purpose of this work was to assess posttraumatic growth (PTG) among radiation medicine staff members at the individual level as well as changes in perceptions of departmental culture after the COVID-19 pandemic. Methods and Materials: An anonymous PTG inventory (PTGI) survey comprising 21 indicators was disseminated to all 213 members of our multicenter radiation department to measure perceptions of change in personal, interpersonal-relationship, and philosophy of life factors using principal-factor analysis. Additionally, 8 department safety-culture indicators from the National Hospital Patient Safety Culture Survey developed by the Agency for Healthcare Research and Quality were included to assess changes in department safety-culture perceptions verses a prepandemic survey. The survey was repeated 15 months later to assess longitudinal trends. Results: With a 56.3% survey-response rate, PTGI factor analysis yielded Cronbach's alpha values exceeding 0.90 for the 3 aforementioned PTG factors. The average growth per indicator was 2.3 (out of 5.0), which fell between small and moderate. The values were 2.4 (personal), 2.1 (interpersonal), and 1.6 (philosophy) for the 3 factors. The total PTGI score (47.7 ± 28.3 out of 105 points) was lower for masked, patient-facing, frontline workers members (41.8 ± 28.4) compared with others (53.1 ± 27.3, P value .001). For the Agency for Healthcare Research and Quality survey there was an improvement of 15% in perceptions of department safety culture, and 7 of the 8 indicators showed improvements compared with baseline. The follow-up survey demonstrated overall sustained findings, albeit with a trend toward declining PTG scores for nonfrontline workers, notably in interpersonal relationships (47.4 ± 27.0, P value .05). Conclusions: A fair-to-moderate degree of PTG was observed in personal and interpersonal relationship factors whereas least growth was noted in spiritual and religious beliefs. Perceptions of department patient-safety culture improved substantially. Sustained improvements were thus perceived at the individual and department levels.

Sé han publicado una gran cantidad de artículos relacionados con la posibilidad de predecir los multiplicadores monetarios en los países industrializados. Sin embargo, este análisis no se ha realizado para las economías en desarrollo donde la inflación usualmente representa un serio problema. Este estudio empírico emplea las técnicas ARMA univariantes, utilizadas en Estados Unidos y Holanda, para modelar los multiplicadores monetarios de tres economías suramericanas. Las simulaciones dinámicas que se obtienen a partir de las ecuaciones desarrolladas se comparan favorablemente con predicciones aleatorias de los multiplicadores en cada una de las economías. Los resultados indican que los analistas de política económica, en los países en desarrollo, pueden aprovechar las técnicas Box-Jenkins al diseñar e implementar la política monetaria.

The goal of this research is to collaborate with a number of different artists to explore the capabilities of robotic musical instruments to cultivate new music. This paper describes the challenges faced in using musical robotics in rehearsals and on the performance stage. It also describes the design of custom software frameworks and tools for the variety of composers and performers interacting with the new instruments. Details of how laboratory experiments and rehearsals moved to the concert hall in a variety of diverse performance scenarios are described. Finally, a paradigm for how to teach musical robotics as a multimedia composition course is discussed.
