Impacts of Error Rate and Therapist Appearance on the Accuracy of Fidelity Data Collection

Procedural fidelity is the extent to which a procedure is implemented as designed. Analyzing procedural-fidelity data can improve treatment outcomes. Fidelity data are generally collected by a supervisor or trained data collector using a checklist that operationalizes each component of the procedure and accounts for errors in implementation of the components. However, little is known about variables that may affect the accuracy of supervisor-collected data generally, and even less is known about variables that may affect the accuracy of procedural-fidelity data. Therefore, the current studies explored the extent to which Board Certified Behavior Analysts (BCBAs) accurately detected programmed fidelity errors when using a tally checklist (Experiment 1) or rating scale (Experiment 2) for a resetting differential reinforcement of other behavior procedure (DRO). Nine participants were exposed to four conditions in which they watched videos of a resetting DRO with two therapists of different races/ethnicities with varied programmed errors (i.e., 80% and 40% fidelity). Participants were generally accurate regardless of the programmed level of fidelity but were slightly less accurate for the low (40%) fidelity condition with one therapist and when using a rating scale

Evaluation of <i>N</i>-Alkyl-bis-<i>o</i>-aminobenzamide Receptors for the Determination and Separation of Metal Ions by Fluorescence, UV-Visible Spectrometry and Zeta Potential

This paper presents the synthesis and evaluation of physicochemical behavior of a new series of N-alkyl-bis-o-aminobenzamides (BOABs) in aqueous solution. The study was targeted to the complexing capacity of five metal ions (Fe2+, Cu2+, Cd2+, Hg2+ and Pb2+) of environmental concern as the medullar principle of a liquid phase sensor for its application in the determination of these metal ions due to its versatility of use. Molecular fluorescence, UV-visible and Zeta potential were measured for five BOABs and the effect of alkyl groups with different central chain length (n = 3, 4, 6, 8 and 10) on physicochemical performance determined. The results have shown that these derivatives present higher sensibility and selectivity for Cu2+ even in the presence of the other metal ions. An additional application test was done adding a pectin (0.1 wt %) solution to the BOAB-Cu+2 complex to obtain a precipitate (flocs) as a potential selective separation process of Cu from aqueous solution. The solid was then lyophilized and analyzed by SEM-EDS, the images showed spheric forms containing Cu+2 with diameter of approximately of 8 &#956;m and 30 wt %

Evaluación de compuestos bis-fluorofóricos en agua del río Tijuana

This work focuses on the use of bis-fluorophore compounds in real water for the detection and removal of metal ions present in the Tijuana river, for this, a previous work of chemical and bacterial analysis of 6 different samples that were taken from the River was used Tijuana. All the sampling sites were carefully selected to obtain an accurate understanding of the current state of the river throughout its course. The TOC, COD, BOD, Nitrogen and phosphorus results showed that dams do not contain high amounts of these parameters, but in the city, center these values are increased due to the possible interversion of city sewer connections to the river (55, 189, 131, 11.9 and 1.1 mg / L, respectively). The points with the highest amount of organic matter were in the city center, so that specific point was chosen for the test of bis-fluorophoric compounds, to ensure the presence of metal ions in the water and it was shown that the water containing fluorescent compounds and in the presence of these bis-fluorophoric compounds there is a lowering of fluorescence. The bacterial analysis showed that the last point of the city, near the border of the USA and Mexico, concentrates a high number of bacteria and that the discharge goes directly to the Pacific Ocean, being a health and environmental problem.Este trabajo se centra en el uso de compuestos bis-fluorofóricos en agua real para la detección y remoción de iones metálicos presentes en el río Tijuana, para esto se utilizó un trabajo previo de análisis químico y bacteriano de 6 muestras diferentes que se tomaron del Río Tijuana. Todos los sitios de muestreo fueron seleccionados cuidadosamente para obtener una comprensión precisa del estado actual del río a lo largo de su curso. Los resultados de TOC, DQO, DBO, Nitrógeno y fósforo mostraron que las presas no contienen cantidades elevadas de estos parámetros, pero al centro de la ciudad estos valores se incrementan por la posible interversión de conexiones del alcantarillado de la ciudad al río (55, 189, 131, 11.9 y 1.1 mg/L, respectivamente). Los puntos con mayor cantidad de materia orgánica fueron en el centro de la ciudad, por lo que se eligió ese punto en específico para la prueba de los compuestos bis-fluorofóricos, para asegurar la presencia de iones metálicos en el agua y se mostró que el agua que contiene compuestos fluorescentes y en presencia de estos compuestos bis-fluorofóricos hay un abatimiento de la fluorescencia. El análisis bacteriano mostró que el último punto de la ciudad, cerca de la frontera de USA y México, se concentra una cantidad elevada de bacterias y que la descarga va directo al océano pacífico, siendo un problema de salud y ambiental
