EVALUATING THE EFFECTS OF DIFFERENT MAGNITUDES OF REINFORCEMENT ON THE PERSISTENCE OF SOCIAL SKILLS LEARNED THROUGH BST IN ADULTS WITH DEVELOPMENTAL DISABILITIES

Otte, Erik Michael 01 August 2015 (has links)
Study 1 examined the usefulness of a BST package to teach conversation skills and job interview skills to young adults with developmental disabilities. Performance was scored in terms of percent of steps correct, according to task analyses. The BST package included instructions, modeling, rehearsal, feedback, and reinforcement. The skills were paired with either a high magnitude of reinforcement or a low magnitude of reinforcement. Study 2 assessed the effects of these different magnitudes of reinforcement on the persistence of the social skills. Results of Study 2 are described in terms of percent of steps correct and also proportion to baseline.

Efeitos do intervalo entre aspirações foliculares e do tratamento com somatotropina bovina recombinante na população folicular e na produção in vitro de embriões bubalinos / Effect of OPU interval and recombinant bovine somatotropin treatment on embryo production in buffalo

Ferraz, Márcio Leão 26 August 2008 (has links)
Foram avaliados os efeitos do intervalo entre aspirações foliculares (IEA; OPU) e do tratamento com somatrotopina bovina recombinante (bST) na produção in vitro de embriões bubalinos. Dezesseis fêmeas foram distribuídas aleatoriamente em quatro grupos (fatorial 2x2): (1) G-Cont7: sessões de OPU uma vez por semana; (2) G-bST7: sessões de OPU uma vez por semana + 500mg de bST a cada 14 dias; (3) G-Cont14: sessões de OPU a cada 14 dias e (4) G-bST14: sessões de OPU + 500mg de bST a cada 14 dias. Os animais do G-Cont7 e G-bST7 foram submetidos a 16 sessões de OPU, e os animais do G-Cont14 e G-bST14 a oito sessões de OPU. Nas sessões realizadas uma vez por semana (G-s/bST) reduziu-se o número de folículos aspirados, de oócitos totais recuperados e de oócitos viáveis (P0,004). O tratamento com bST aumentou o número de folículos aspirados (P<0,0001), o total de oócitos recuperados e a taxa de recuperação (P=0,07). No entanto, nem o IEA e nem o tratamento com bST aumentaram a produção in vitro de embriões bubalinos. / It was evaluated the effect of OPU interval and bST treatment on embryo production in buffalo. Sixteen females were randomly assigned in 4 groups, in a 2x2 factorial experimental design: (1) G-Cont7: OPU session each seven days; (2) G-bST7: OPU session each seven days plus 500mg of bST each 14 days; (3) G-Cont14: OPU session each 14 days and (4) G-bST14: OPU session plus 500mg of bST each 14 days. Animals of G-Cont7 and G-bST7 were submitted to 16 OPU sessions, and those of G-Cont14 and G-bST14 to 8 OPU sessions. The OPU session performed every week (G-s/bST) decreased the number of aspirated follicles, and the number of total and viable recovery oocytes (P0.004). The treatment with bST increased the number of aspirated follicles (P<0.0001), the number of recovery oocytes and the oocyte recovery rate (P=0.07). However, neither OPU interval nor bST treatment increased the in vitro embryo production in buffalo.

AN EVALUATION OF THE USE OF BST TO TEACH A DATA COLLECTION PROCEDURE TO PARENTS OF CHILDREN WITH DISABILITIES

Dvorak, Kirsten L. 01 December 2014 (has links)
AN ABSTRACT OF THE THESIS OF Kirsten Dvorak, for the Master's of Science degree in Behavior Analysis and Therapy, presented on *October 17, 2014, at Southern Illinois University Carbondale. TITLE: AN EVALUATION OF THE USE OF BST TO TEACH A DATA COLLECTION PROCEDURE TO PARENTS OF CHILDREN WITH DISABILITIES MAJOR PROFESSOR: Dr. Joel Ringdahl Behavioral skills training (BST) has been utilized with many different populations for a variety of purposes. This training package has been employed for the purposes of either behavior reduction or skill acquisition and has been successfully employed with staff, parents, and individuals with intellectual disabilities. This present study utilized a BST training package to teach ABC data collection to three parents of children with disabilities. This study extended Shand and Miltenberger's (2013) study by including a post-BST component where the parents collected data on their own children. This study included this component to help determine if the skills learned during BST could be generalized. Two week follow-up sessions were conducted as well. Results indicated that the percentage of correct ABC data forms increased post-BST, and were maintained at follow-up. The study suggested that the skills were generalized to the parent's own children. These results propose that behavioral skills training is an effective method to teach parents to collect data on their children. Future research should be conducted to include longer follow up sessions, and future research should also replicate the study. Replication with similar results would further prove that the skills were generalized to children of the participants following the BST training package.

Elaboration de capacités variables ferroélectriques à base de (Ba, Sr)TiO3 pour applications radiofréquences

Guigues, Benoit 16 December 2008 (has links) (PDF)
L'industrie de la téléphonie mobile est soumise à des contraintes de miniaturisation, et requiert de plus en plus la présence d'éléments variables dans les circuits intégrés. Le but de ce travail de thèse a été de réaliser une capacité variable pour une application de puissance dans un téléphone portable. Les matériaux ferroélectriques à structure pérovskite s'avèrent être potentiellement intéressants pour ce type d'application. Nous nous sommes donc intéressés à l'intégration du titanate de strontium et baryum ((Ba,Sr)TiO3) dans une capacité fonctionnant en gamme Radio Fréquences (typiquement autour de 2 GHz).<br /><br />La première partie du travail a été d'étudier les propriétés structurales et diélectriques du BST, avec pour but de les relier entre elles. Différentes études ont été menées dans cette partie, notamment sur les effets de taille de grains, de contraintes (homogènes et inhomogènes) dans les couches épaisses, de taille sur des couches minces de plusieurs épaisseurs, ou encore d'une cristallisation partielle sur la microstructure et les performances du matériau.<br /><br />Grâce à l'étude menée au niveau du matériau, nous avons pu proposer une intégration dans une architecture de capacité hybride RF/DC. L'optimisation du dépôt de BST a été faite par plans d'expériences, puis la réalisation de plusieurs dispositifs a permis d'observer différents effets sur le composant. L'influence du substrat de Silicium a été réduite grâce à différentes solutions. L'effet du recuit de cristallisation a été étudié sur la capacité RF. Enfin, nous avons montré la possibilité d'actionner indépendamment le matériau ferroélectrique par le biais d'électrodes DC.

Nuclei-Specific Response to Pain in the Bed Nucleus of the Stria Terminalis

Morano, Tania J. 01 October 2007 (has links)
The bed nucleus of the stria terminalis (BST) is a basal forebrain cluster of several distinct nuclei. It has been proposed that the BST coordinates autonomic, neuroendocrine, and behavioral functions through the integration and organization of homeostatic responses necessary for survival. Dysfunction of the BST contributes to pathophysiological states such as addiction, anxiety and aggression. Based on anatomical and behavioral studies, the BST could be a key contributor to descending modulation of nociception as well as the physiological responses related to the affective aspect of the pain experience. The objective of the present study was to further understand the neurophysiological bases underlying the involvement of the 7 anterior nuclei of the BST in pain. Using c-Fos as an indicator of neuronal activation, the results demonstrate that acute noxious stimulation produced an increase in the number of c-Fos immunoreactive cells (c-Fos-IR) in the dorsal anteromedial (dAM) and fusiform (FU) nuclei, while non-noxious stimulation did not increase c-Fos-IR in any of the nuclei examined. Chronic neuropathic pain induced by chronic constriction injury (CCI) did not alter basal c-Fos-IR in the FU or dAM. Unlike in the naïve condition, the number of c-fos-IR cells in the FU induced by acute noxious stimulation was attenuated in animals with either CCI or sham surgery compared to naive rats. In contrast, c-Fos-IR induced by acute noxious stimulation in the dAM was not affected by CCI or sham surgery. Acute noxious stimulation in animals that received CCI exhibited increased c-Fos expression in the ventromedial (vAM) nucleus of the BST, a finding not evident in naïve or sham control groups. Finally, there was an increase in c-Fos-IR in the oval (OV) nucleus of sham-operated, but not naive or CCI rats. This study reveals for the first time that pain induces neuronal activity in the BST in a nuclei- and condition-specific way. Given the efferent projection patterns from the BST, this system may relay supraspinal information to the periphery to produce physiological responses related to the affective pain experience. / Thesis (Master, Neuroscience Studies) -- Queen's University, 2007-09-28 14:36:55.632

TRAINING PARAPROFESSIONAL USE OF DIFFERENTIAL REINFORCEMENT OF OTHER BEHAVIOR PROCEDURES USING BEHAVIORAL SKILLS TRAINING

Havlicek, Alexa Ann 01 December 2017 (has links)
AN ABSTRACT OF THE THESIS OF Alexa A. Havlicek, for the Master of Science degree in Behavior Analysis, presented on November 3, 2017 at Southern Illinois University. TITLE: TRAINING PARAPROFESSIONAL USE OF DIFFERENTIAL REINFORCEMENT OF OTHER BEHAVIOR PROCEDURES USING BEHAVIORAL SKILLS TRAINING MAJOR PROFESSOR: Dr. Ruth Anne Rehfeldt Students with disabilities often exhibit problem behaviors in the classroom. Differential Reinforcement of Other Behaviors (DRO) has been found to be an effective strategy in decreasing problem behaviors and increasing other appropriate behaviors for students with disabilities. Research has found that Behavioral Skills Training (BST) can be an effective and efficient way to train paraprofessionals to implement classroom procedures. There were three participants included in the current study. Diane was a 58 year-old female that had been working at the school for 9 years. Dale was a 29 year-old male who had been working for the school for 2 months. Gary was a 25 year-old male who had been working for the school for 3 years. Limited research has been conducted using BST to train paraprofessionals how to implement DRO procedures in the classroom. Therefore, the purpose of this study was to evaluate the effectiveness of BST on paraprofessional’s percentage of correct implementation of DRO procedures using a multiple-baseline design. Results showed that Diane had a mean of 0% correct implementation of DRO procedures during baseline, which, increased to 89% following intervention. Dale had a mean of 1.7% and this increased to 90% following intervention. Gary had a mean of 5%, which, increased to 85% following intervention. Keywords: DRO, paraprofessionals, students with disabilities, BST

Identifying Sources of Fecal Pollution in the Appomattox River Watershed

McKinney, Julie Michelle 02 June 2004 (has links)
Sources of E. coli were determined from impaired waterways in the Appomattox River watershed (in the lower Piedmont and South-Central Virginia) for the development of bacterial Total Maximum Daily Loads (TMDLs). The Appomattox River watershed is primarily undeveloped with 70.8% of the land forested, 17.0% used for agriculture (mainly livestock production), and 7.7% classified as water, wetland or barren land. The remaining 4.5% is developed for residential, commercial, and industrial land uses (mainly within the city of Petersburg). Using Antibiotic Resistance Analysis, a known source library of 1,280 E. coli isolates (320 isolates per source) was constructed. Water samples were collected monthly for between eleven and fourteen months (11/02-12/03) from 40 locations throughout the Appomattox watershed and analyzed for fecal coliforms, E. coli, and resistance to 7 antibiotics of varying concentrations. A total of 486 water samples (9,907 isolates) were analyzed during the study. The objectives of this study were verify that each sampling site exceeded state bacterial count standards (using fecal coliform data), to compare the Discriminate Analysis and Logistic Regression statistical models for use in the classification of isolates, and finally to determine the source of contamination at each site. The fecal coliform and E.coli data was used to determine if each site exceeded state standards during the assessment period. Thirty-eight of the sites exceeded the fecal coliform standard at least 10% of the time, and thirty-three exceeded the E.coli standard at least 10% of the time. Discriminate Analysis (DA) is typically used to classify isolates, but the results obtained from the DA model were unrealistic based on the watershed land uses. By statistically analyzing the original 1,280 E.coli isolates six different ways, a more appropriate classification of isolates was determined. The six analyzing methods were Regular DA and Logistic Regression (LR); DA and LR where each isolate whose probability fell below 80% was deleted; DA and LR where each isolate whose probability fell below 80% was used to create an Unknown category. The Logistic Regression model with an Unknown category proved to be the most appropriate. By using the Logistic Regression model, with Unknown category, to classify isolates, twenty five of the forty sites were discovered to be contaminated predominately with Livestock and fourteen of the sites predominately by Wildlife. One site was equally divided between these two categories. Human and Pet contamination were not dominant at any of the forty sites. This comparison of the DA and LR statistical methods could change the analysis standard for Bacterial Source Tracking and suggests that the model required to classify isolates depends on the watershed characteristics. / Master of Science
