Kato's Perturbation Theorem and honesty theory

Wong, Chin Pin January 2015 (has links)
We study an additive perturbation theorem for substochastic semigroups which is known as Kato's Theorem. There are two previously-known generalisations of Kato's Theorem, namely for abstract state spaces and for KB-spaces. We prove a version of Kato's Theorem for a class of spaces which encompasses both, namely ordered Banach spaces with generating cone and monotone norm. We also study a property of the perturbed semigroup in Kato's Theorem known as honesty of the semigroup. We add a few results to the fairly extensive existing theory of honesty for Kato's Theorem for abstract state spaces. In light of our new generalisation of Kato's Theorem to ordered Banach spaces with monotone norm, we investigate generalising the theory of honesty to these spaces as well. The results for the general case are less complete as many of the results for the case of abstract state spaces depend on the additive norm structure of the space. We also consider some new applications of honesty theory in abstract state spaces. We begin by applying honesty theory to the study of the heat equation on graphs. We prove that honesty of the heat semigroup coincides with a concept known as stochastic completeness of the graph which has been studied independently of honesty. We then look at the application of honesty theory to quantum dynamical semigroups. We show that honesty is the natural generalisation of the concept of conservativity of quantum dynamical semigroups. Conservative quantum dynamical semigroups are known to have certain "nice" properties. We show that similar properties hold for honest semigroups using honesty theory results. Finally, we consider a form of boundary perturbations in the context of transport semigroups. There exists an analogous theory of honesty for this set-up. We formulate a general result from which honesty results of both Kato's Theorem and transport semigroups can be derived.

Decreasing Problematic Throwing Behavior in a Child with Autism Through Parent Delivered Fixed-time Schedules of Noncontengent Reinforcement (NCR)

Green, Lori Jean 01 August 2015 (has links)
The purpose of this study was to examine the effects of parent delivered non-contingent reinforcement (NCR) on decreasing throwing behavior exhibited by a young child with autism. During the pretreatment phase of the experiment the participant went a functional analysis to determine the target behavior of throwing. Baseline data was collected followed by the intervention phase. During the intervention phase, the non-contingent reinforcement (NCR) procedures were conducted. Attention was given to the participant on a fixed-time schedule and was influenced based on the participant’s behavior. The schedule of reinforcement was slowly increase with the decrease or lack of throwing attempts. Furthermore, this study aimed to determine whether parent delivered fixed-time schedules of non-contingent reinforcement decrease the non-preferred activities of throwing objects.

Orientador: Antonio Bento Alves de Moraes / Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Odontologia de Piracicaba / Made available in DSpace on 2018-08-12T20:02:19Z (GMT). No. of bitstreams: 1 Tomita_LauraMendes_D.pdf: 494168 bytes, checksum: 6212c45d72e7cbbd71b1e651b4e6c3b6 (MD5) Previous issue date: 2009 / Resumo: A experiência odontológica pode ser considerada uma situação potencialmente geradora de ansiedade para a criança; esta situação envolve um conjunto de variáveis desconhecidas e invasivas que podem desencadear respostas que caracterizam desconforto e sofrimento psicológico, assim como respostas de não-colaboração que dificultam e/ou impedem a realização do tratamento. Objetivando controlar estas respostas, pesquisadores têm utilizado estratégias comportamentais e farmacológicas na tentativa de auxiliar a criança a enfrentar o tratamento e prevenir a ocorrência destes comportamentos. Este trabalho tem como objetivo analisar os efeitos do diazepam sobre os comportamentos de crianças expostas a tratamento odontológico, utilizando a metodologia de análise funcional do comportamento. Foram selecionadas dez crianças com idade entre 42 e 48 meses, com história de não-colaboração com o tratamento odontológico, que receberam atendimento durante 4 sessões, nas quais foi administrado diazepam (0,5 mg/Kg de peso) ou placebo, de modo duplo-cego. As sessões foram filmadas em vídeo e transcritas na íntegra por dois observadores independentes (fidedignidade de 85%); posteriormente, eventos comportamentais verbais e motores das crianças foram registrados e procedeu-se à identificação de seqüências comportamentais de interação denominadas como episódios comportamentais. Os episódios foram classificados em duas categorias funcionais: episódios concorrentes e episódios não-concorrentes. Posteriormente a esta classificação, todos os comportamentos da criança que ocorriam a cada episódio foram categorizados. Foram identificadas 24 categorias de comportamento da criança, as quais foram analisadas funcionalmente. Um modelo de análise funcional do comportamento infantil no contexto de tratamento odontológico foi desenvolvido para a realização deste trabalho. O diazepam teve um efeito potencializador das respostas de não-colaboração com o tratamento; quando as crianças estavam sob efeito da droga, o número de episódios concorrentes foi maior (60,29%) do que aquele apresentado nas sessões placebo. Outro efeito da medicação apontado neste trabalho foi a inibição de comportamentos de interação da criança com o dentista, tais com Protestar e Expressar sentimentos e sensações. Além disso, a droga também exacerbou comportamentos agressivos das crianças, os quais ocorreram exclusivamente nas sessões diazepam e em episódios concorrentes. Assim neste trabalho observou-se que o diazepam foi pouco efetivo para o manejo comportamental na amostra estudada e interferiu negativamente no processo de interação dentista-criança. A metodologia utilizada para análise se mostrou eficaz, permitindo uma descrição seqüencial e detalhada do comportamento da criança no contexto de tratamento odontológico. O conhecimento e aplicação deste método podem possibilitar ao cirurgião-dentista um melhor entendimento do comportamento da criança na situação odontológica e permitir a seleção e planejamento de procedimentos clínicos, estratégias farmacológicas e comportamentais a fim de auxiliar a criança a enfrentar situações adversas em saúde. / Abstract: The pediatric dental experience can be considered a situation that evokes anxiety. This situation involves a set of unknown and invasive variables that can trigger discomfort responses, psychological suffering, as well as non-cooperative behaviors that prevent the completion of treatment. In an attempt to control those responses, researchers have used behavioral and pharmacological strategies to help children to cope the treatment and prevent the occurrence of these behaviors. This paper aims to analyze the effects of diazepam on children's behavior exposed to dental treatment, using the methodology of behavior functional analysis. Ten children, ages between 42 and 48 months, with a history of non-cooperation with dental treatment were selected and received dental care for 4 sessions, in which diazepam (0.5 mg / kg body weight) or placebo were administered in a double-blind condition. All sessions were recorded on videotape and transcribed by two independent observers (reliability of 85%). Afterwards verbal and motor children's behavior was described and researchers identified behavioral sequences of interaction referred as behavioral episodes. The episodes were classified into two functional categories: concurrent and non-concurrent episodes. After this classification, children's responses that occurred in each episode were categorized. It was identified 24 categories of children's behavior, which were functionally analyzed. A model for functional analysis of behavior in the context of children's dental treatment was developed for this work. Diazepam had an enhanced effect on non-cooperative responses; when children were under influence of drug, the number of concurrent episodes was higher (60.29%) than that presented in placebo sessions. Another effect of the medication noted in this study was the inhibition of children's interaction with the dentist, such as protest and expression feelings. Moreover, drug also exacerbated aggressive behaviors, which occurred only in diazepam sessions in concurrent episodes. It was observed that diazepam was ineffective in behavior management and interfered negatively in dentist-child interaction. The analysis methodology used for the present research was effective, allowing a sequential and detailed description of children's behavior in the context of dental treatment. The knowledge and application of this method may enable professionals a better understanding of children's behavior in the dental situation and allow the selection and planning of clinical procedures, pharmacological and behavioral strategies to help the child to face invasive health treatment situations. / Doutorado / Farmacologia, Anestesiologia e Terapeutica / Doutor em Odontologia
