We monitored benthic macroinvertebrates and adult caddisflies along an agricultural stream continuum upstream, within, and downstream of a small forested preserve. The habitat upstream of all sites was 460% disturbed by agricultural activities. The percentage of riparian disturbance was markedly lower adjacent to the sites inside the preserve than those outside. Water physicochemical factors did not exhibit clear changes among sites, except for nitrate concentration, which was highest upstream of the preserve. Biological diversity of adult caddisflies was significantly higher within the preserve. Biological diversity of benthic invertebrates exhibited similar results except for non-significance between the upstream and preserve sites. Pollution tolerance and percentage of filtering collector metrics were unchanged among sites for both assemblages. The percentage of adult caddisflies in the shredder functional group increased significantly within the preserve but remained small relative to that of pollution-tolerant filtering collectors. The small terrestrial preserve promoted a three-fold increase in species diversity, even without corresponding changes in water quality or trophic structure. Such an increase, however, may not be as detectable with traditional benthic biomonitoring techniques due to the difficulties of sampling benthic microhabitats representatively and identifying specimens to the species level.
Investigation of transfer of differential eyelid conditioning in successive discriminations, using unrelated words, unfamiliar forms, numerals, and spelled numbers as discriminanda revealed almost immediate and complete transfer for unrelated words after the slower initial differential conditioning. Transfer with unfamiliar forms, numerals, and spelled numbers was slower and showed elevation of responding to the negative stimulus. The slower transfer for forms was thought to be related to their unfamiliarity, and the slower transfer for numerals and spelled numbers was thought to be caused by mediation between positive and negative stimuli arising from preexperimental associations between the numbers. Implications of the numerous processes apparently involved-slow initial response learning, rapid stimulus substitution, and stimulus familiarization-were outlined.
Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations.
This presentation will familiarize participants with the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, which creates a universal language regarding the infant's sensory development for staff and families in the neonatal intensive care unit (NICU). Implementation of the SENSE program in this study enhanced caregiver satisfaction of infant care in the NICU and improved overall feeding outcomes. The findings of this study may be beneficial for OTs who work in the NICU setting.

As the number of homes located in condominiums increases, investigations should be promoted to determine the implied price of additional amenities over the total price of the property. This study evaluated the impact of multi-attribute and construction variables on the value of condominiums in Costa Rica, using a hedonic pricing model of the amenities that influence the total price. Information from condominiums located in all provinces of the country was used to determine the importance of the variables studied. Through multiple regression analysis, it was determined that nine amenities explain the behavior of the total price. This study shows that the project’s internal and external variables have a significant effect on sales prices and consumers’ purchasing decisions. The most significant variables were income, construction area, access to a pool and gym, and the type of condominium.
Esta investigación se enfocó en el cultivo de palma aceitera en la zona sur de Costa Rica, por el alto impacto que genera en el desarrollo económico de agricultores costarricenses. Se ajustó la curva de crecimiento del rendimiento de la palma aceitera a lo largo del ciclo de vida del cultivo y se comparó la eficiencia de pronóstico de ocho modelos de crecimiento no lineal con base en diferentes criterios estadísticos y pruebas de normalidad. Posteriormente, se aplicó el método de transformación Box-Cox para corregir la ausencia de normalidad en los residuos. Los modelos no lineales aplicados fueron adecuados para pronosticar el rendimiento de palma aceitera; el modelo Morgan-Mercer-Flodin produjo las mejores estadísticas de ajuste. Esta investigación constituye un insumo para las prácticas de renovación de plantaciones, así como para la valoración económica de cultivos que se prendan como garantía bancaria.
