Previous issue date: 2014-12-12 / The present study analyzed the verbal responses of two people with a psychiatric diagnosis
of bipolar disorder. Participants were one female aged 18, and one male, 35 years of age.
For analysis of antecedent and consequent events that controlled the verbal responses
indicative of mood swings, was applied the strategies of indirect functional assessment,
and direct and experimental, with the use of multiple conditions with four main conditions:
attention condition, demand, alone, and control. The attention condition was subdivided
into three sub conditions: medicine-condition, family- attention and cellular care-attention
for P1; and exclamation attention, sign attention of approval and doubt attention for P2. An
intervention program was accomplished through the design of alternate treatments of type
ABCA followed by follow-up. The first purpose was to use functional assessment
methodology to verify the controlling variables that produced and maintained the verbal
responses of people diagnosed with bipolar disorder. Other was to reduce problem
behaviors, while new desired behaviors were installed. The results suggest that social
attention controlled about the verbal responses from both participants, whose frequencies
decreased throughout the treatment program. These findings were discussed in terms of the
importance of using functional assessment process for classes of problem behaviors in
people with diagnoses of bipolar disorder. / O presente trabalho analisou as respostas verbais de duas pessoas com diagnóstico
psiquiátrico de transtorno bipolar. Os participantes foram um do sexo feminino, com 18
anos e masculino, com 35 anos de idade. Para análise dos eventos antecedentes e
consequentes que controlavam as respostas verbais indicativas de oscilação de humor,
aplicaram-se as estratégias de avaliação funcional indireta, direta e experimental com o uso
do delineamento de múltiplas condições com quatro condições principais: condição de
atenção, demanda, sozinho e controle. A condição de atenção foi subdividida em três
subcondições: atenção-medicamentos, atenção-familiares e atenção-celular para P1; e
atenção-exclamação, atenção- sinal de aprovação e atenção- dúvida para P2. Um programa
de intervenção foi realizado por meio do delineamento de tratamentos alternados do tipo
ABCA seguido de follow-up. O primeiro objetivo foi utilizar a metodologia de avaliação
funcional para verificar as variáveis controladoras que produziram e mantiveram as
respostas verbais de pessoas com diagnóstico de transtorno bipolar. Outro foi reduzir os
comportamentos-problema, enquanto novos comportamentos desejados fossem instalados.
Os resultados sugerem que a atenção social exerceu controle sobre as respostas verbais de
ambos as participantes, cujas frequências diminuíram ao longo do programa de
tratamento. Esses achados foram discutidos em termos da importância do uso do
processo de avaliação funcional para identificar classes de comportamentos-problema de
pessoas com diagnósticos de transtorno bipolar e propor intervenção.

Previous issue date: 2016-02-19 / The current study involved evaluation and treatment of the antecedent and consequent
events which were keeping inappropriate speeches (FI) of a person with the diagnosis of
schizophrenia. The participant was a male, single, 30 years old. Strategies of the functional
evaluation process through indirect observation, direct observation and functional analysis
(experimental) were used. The functional analyses involved the manipulation of
environmental events in for main conditions: attention, demand escaping, alone and
control. The condition attention was subdivided into: (1.1) attention-reprimand, (1.2)
attention-inquiry and (1.3) attention-reverse. The results have showed that there was a
higher record of FI in the conditions of attention and demand escaping, than in the other
conditions: alone and control. It became clear, therefore, that the FI were kept through
positive and negative reinforcement sources. For the conduction of intervention, the
outline of alternate treatments of the type ABC was used, proceeded by follow-up. For the
treatment itself, on phase B, it was applied differential reinforcement of the type
alternative differential reinforcement (DRA) of speeches topographically different from
the FI combined with its extinction (EXT), procedure that has made possible to reduce the
FI and increase the appropriate speeches (FA). On phase C the stimuli analysis (AE) was
taught which comprehended in the participant to evaluate the current events in his
immediate environment with his physical descriptions. In the follow-up phase, the results
point to the maintaining of the issuance of FA in higher frequency than in respect to the FI.
The objectives of this study were achieved. Studies such as this one, among others
available in literature, show that with behavior analysis tools is possible to increase the
frequency of appropriate behaviors in people who have the psychiatric diagnosis of
schizophrenia. / O presente estudo envolveu avaliação e tratamento dos eventos antecedentes e
consequentes que mantinham as falas inapropriadas (FI) de uma pessoa com o diagnóstico
de esquizofrenia. O participante era do sexo masculino, solteiro, com idade de 30 anos.
Utilizou-se de estratégias do processo de avaliação funcional por observação indireta,
observação direta e a análise funcional (experimental). A análise funcional envolveu a
manipulação de eventos ambientais em quatro condições principais: atenção, fuga de
demanda, sozinho e controle. A condição atenção foi subdividida em: (1) atençãoreprimenda,
(2) atenção-interrogação e (3) atenção-inversa. Os resultados mostraram que
houve maior registro de FI nas condições de atenção e fuga de demanda, do que nas
demais condições: sozinho e controle. Evidenciou-se, portanto, que as FI foram mantidas
por fontes de reforçamento positivo e negativo. Para a realização de intervenção, utilizouse
o delineamento de tratamentos alternados do tipo ABC, seguido por follow-up. Para o
tratamento, em si, na fase B, foi aplicado reforço diferencial do tipo reforçamento
diferencial alternativo (DRA) de falas topograficamente diferente das FI combinado com a
sua extinção (EXT), procedimento que possibilitou reduzir as FI e aumentar as falas
apropriadas (FA). Na fase C foi ensinada a análise dos estímulos (AE) que compreendeu
em o participante avaliar os eventos presentes em seu ambiente imediato com as suas
descrições físicas. Na fase de follow-up, os resultados apontam para a manutenção da
emissão de FA em maior frequência que com relação às FI. Os objetivos desse estudo
foram alcançados. Estudos como este, dentre outros disponibilizados na literatura,
mostram que com instrumentos da análise do comportamento, torna-se possível aumentar
frequência de comportamentos apropriados em pessoas que apresentam o diagnóstico
psiquiátrico de esquizofrenia.

Previous issue date: 2010-03-15 / The present study aimed at investigating the problem behavior of an autistic child in a
specialized service using the principles of behavior analysis. The participant was a 10-
year-old male child. All the sessions were video-recorded and the behavior class of
physical aggression to the mother was selected for intervention. For the functional analysis
of the conditions that probably controlled or maintained the behavior of physical
aggression to the mother, we used the design of multiple conditions with three main
conditions and six sub-conditions: 1) condition of attention, manipulated in four subconditions
- (1.1) attention, order; (1.2) attention, physical contact; (1.3) attention,
reprimand; (1.4) attention, game; 2) condition alone, manipulated in two sub-conditions -
(2.1) alone; (2.2) alone with reinforcers; 3) condition of demand. The results demonstrated
that in all conditions of attention the occurrences of physical aggression were high, the
same occurring in the condition of demand. In both sub-conditions alone, the frequency of
behavior of physical aggression to the mother was zero. Since our data pointed to the
control of social attention as a controller of the participant s problem behavior, we decided
to adopt a program of treatment employing the ABA reversal design and a follow-up. The
design was initiated by data collection of Baseline I (A), followed by the phase of
Intervention (B), and another phase of Baseline II (A). During the sessions of intervention,
we used a program of treatment employing differential reinforcement of alternative
answers (DRA), offering social reinforcement for desired behaviors and withdrawing
social attention for the behavior of physical aggression to the mother in an extinction
procedure (EXT). Our results demonstrated that withdrawing social attention for the
behavior of physical aggression decreased these occurrences and offering social
reinforcement for desired behaviors increased their frequency. These results showed that
the program of treatment and not other variables was responsible for the changes in the
problem behavior of the participant. / O presente estudo teve como objetivo investigar o comportamento-problema de uma
criança com o diagnóstico de autismo em uma unidade de tratamento especializada
utilizando os princípios da análise do comportamento. O participante foi uma criança do
sexo masculino com 10 anos de idade. Todas as sessões foram registradas em vídeo e a
classe comportamental de agressões físicas à mãe foi selecionada para sofrer intervenção.
Para a análise funcional das condições que provavelmente controlavam ou mantinham o
comportamento de agressão física à mãe, foi utilizado o delineamento de múltiplas
condições com três condições principais e seis subcondições: 1) condição de atenção,
manipulada em quatro subcondições - (1.1) atenção, ordem; (1.2) atenção, contato físico;
(1.3) atenção, reprimenda; (1.4) atenção, jogo; 2) condição de demanda; 3) condição de
sozinhos, manipulada em duas subcondições - (3.1) sozinhos; (3.2) sozinhos com os
reforçadores. Os resultados demonstraram que em todas as condições de atenção as
ocorrências das agressões físicas foram elevadas, o mesmo ocorrendo na condição de
demanda. Já nas duas subcondições de sozinhos, a frequência dos comportamentos de
agressão física à mãe foi igual a zero. Uma vez que os dados apontaram para o controle da
atenção social como controladora do comportamento-problema do participante, optou-se
por um programa de tratamento fazendo uso do delineamento de reversão do tipo A-B-A
seguido de follow-up. O delineamento foi iniciado com a coleta de dados de Linha de Base
I (A), seguida da fase de Intervenção (B) e de outra fase de Linha de Base II (A). Nas
sessões de intervenção, foi usado um programa de tratamento empregando reforçamento
diferencial de respostas alternativas (DRA), sendo disponibilizado reforço social para os
comportamentos desejados e retirada da atenção social para o comportamento de agressão
física à mãe, em um procedimento de extinção (EXT). Os resultados demonstraram que a
retirada da atenção social contingente ao comportamento de agressão física diminuiu suas
ocorrências e a apresentação de reforço social para os comportamentos desejados
aumentou suas frequências. Esses resultados mostraram que o programa de tratamento e
não outras variáveis foi responsável pelas mudanças no comportamento-problema do
participante.

A equação de Dirac com uma superposição do campo de Aharonov-Bohm e um campo magnético uniforme colinear / The Dirac equation with a superposition of the Aharonov-Bohm field and a uniform magnetic collinear fieldSmirnov, Andrei Anatolyevich 16 August 2004 (has links)
Neste trabalho é estudada a equação de Dirac com uma superposição do campo de Aharonov-Bohm (AB) e de um campo magnético colinear uniforme, que nós chamamos de campo magneto-solenoidal (MS). Usando a teoria de von Neumann das extensões auto-adjuntas de operadores simétricos, nós construímos no caso de 2+ 1 dimensões uma família uni paramétrica de hamiltonianos de Dirac auto-adjuntos especificados pelas condições de contorno no solenóide AB, e encontramos o espectro e as auto-funções para cada valor do parâmetro de extensão. Em seguida, reduzimos o problema em 3+ 1 dimensões ao problema em 2+ 1 dimensões pela escolha apropriada do operador de spin, o que permite realizar todo o programa de construção de extensões auto-adjuntas, e assim, também permite obter os espectros e auto-funções em termos do problema em 2+1 dimensões. Ademais, nós apresentamos o método reduzido de extensões auto-adjuntas do hamiltoniano radial de Dirac com o campo MS. Depois nós consideramos o caso regularizado do solenóide de raio finito. Nós estudamos a estrutura das autofunções e a sua dependência com o comportamento do campo magnético dentro do solenóide. Considerando o limite de raio zero para o valor fixo do fl.mm magnético, nós obtemos um hamiltoniano auto-adjunto particular que corresponde à condição de contorno específica para o caso do campo magneto-solenoidal com o solenóide AB. Nós chamamos estes casos particulares das extensões auto-adjuntas extensões naturais. Para completeza da investigação nós estudamos também o comportamento de uma partícula sem spin no campo magneto-solenoidal regularizado. A etapa seguinte da investigação é a construção das funções de Green da equação de Dirac com o campo MS em 2 + 1 e 3 + 1 dimensões. As funções de Green são construídas por meio de um somatório sobre o conjunto completo das soluções da equação de Dirac. Ao construir as funções de Green, nós usamos as soluções exatas da equação de Dirac, que são relacionadas a valores específicos do parâmetro de extensão. Estes valores correspondem às extensões naturais. Depois nós estendemos os resultados ao caso em 3 + 1 dimensões. Nós apresentamos também as funções de Green não relativísticas e as funções de Green de uma partícula relativística escalar. / ln the present work the Dirac equation with the supereposition of the Aharonov-Bohm (AB) field and a collinear uniform magnetic field, which we call a magnetic-solenoid (MS) field, is studied. Using von Neumann\'s theory of the self-adjoint extensions of symmetric operators, in 2 + 1 dimensions we construct a one-parameter family of self-adjoint Dirac Hamiltonians specified by boundary conditions at the AB solenoid and find the spectrurn and eigenfunctions for each value of the extension parameter. We reduce the (3 + 1)-dimensional. problem to the (2 + 1)-dimensional one by a proper choice of the spin operator, which allows realizing all the programme of constructing self-adjoint extensions and finding spectra and eigenfunctions in the previous tenns. We also present the reduced self-adjoint extension method for the radial Dirac Hamiltonian with the MS field. We then turn to the regularized case of finite-radius solenoid. We study the structure of the corresponding eigenfunctions and their dependence on the behavior of the magnetic field inside the solenoid. Considering the zero-radius limit with the fixed value of the magnetic flux, we obtain a concrete self-adjoint Hamiltonian corresponding to a specific boundary condition for the case of the magnetic-solenoid field \'W-ith the AB solenoid. These particular cases of self-adjoint extensions we call natural extensions. For completeness we also study the behavior of the spinless particle in the regularized magnetic-solenoid field. Successive step of our investigation is a construction of the Green functions of the Dirac equation with the MS field in 2 + 1 and 3 + 1 dimensions. The Green functions are constructed by means of summation over the complete set of solutions of the Dirac equation. Constructing the Green functions, we use the exact solutions of the Dirac equation that are related to the specific values of the extension parameter. These values correspond to the natural extension. Then we extend the results to the (3 + 1)-dimensional case. For the sake of completeness, we present nonrelativistic Green functions and Green functions of the relativistic scalar particle.

Functional data analysis in orthogonal designs with applications to gait patternsZhang, Bairu January 2018 (has links)
This thesis presents a contribution to the active research area of functional data analysis (FDA) and is concerned with the analysis of data from complex experimental designs in which the responses are curves. High resolution, closely correlated data sets are encountered in many research fields, but current statistical methodologies often analyse simplistic summary measures and therefore limit the completeness and accuracy of conclusions drawn. Specifically the nature of the curves and experimental design are not taken into account. Mathematically, such curves can be modelled either as sample paths of a stochastic process or as random elements in a Hilbert space. Despite this more complex type of response, the structure of experiments which yield functional data is often the same as in classical experimentation. Thus, classical experimental design principles and results can be adapted to the FDA setting. More specifically, we are interested in the functional analysis of variance (ANOVA) of experiments which use orthogonal designs. Most of the existing functional ANOVA approaches consider only completely randomised designs. However, we are interested in more complex experimental arrangements such as, for example, split-plot and row-column designs. Similar to univariate responses, such complex designs imply that the response curves for different observational units are correlated. We use the design to derive a functional mixed-effects model and adapt the classical projection approach in order to derive the functional ANOVA. As a main result, we derive new functional F tests for hypotheses about treatment effects in the appropriate strata of the design. The approximate null distribution of these tests is derived by applying the Karhunen- Lo`eve expansion to the covariance functions in the relevant strata. These results extend existing work on functional F tests for completely randomised designs. The methodology developed in the thesis has wide applicability. In particular, we consider novel applications of functional F tests to gait analysis. Results are presented for two empirical studies. In the first study, gait data of patients with cerebral palsy were collected during barefoot walking and walking with ankle-foot orthoses. The effects of ankle-foot orthoses are assessed by functional F tests and compared with pointwise F tests and the traditional univariate repeated-measurements ANOVA. The second study is a designed experiment in which a split-plot design was used to collect gait data from healthy subjects. This is commonly done in gait research in order to better understand, for example, the effects of orthoses while avoiding confounded analysis from the high variability observed in abnormal gait. Moreover, from a technical point of view the study may be regarded as a real-world alternative to simulation studies. By using healthy individuals it is possible to collect data which are in better agreement with the underlying model assumptions. The penultimate chapter of the thesis presents a qualitative study with clinical experts to investigate the utility of gait analysis for the management of cerebral palsy. We explore potential pathways by which the statistical analyses in the thesis might influence patient outcomes. The thesis has six chapters. After describing motivation and introduction in Chapter 1, mathematical representations of functional data are presented in Chapter 2. Chapter 3 considers orthogonal designs in the context of functional data analysis. New functional F tests for complex designs are derived in Chapter 4 and applied in two gait studies. Chapter 5 is devoted to a qualitative study. The thesis concludes with a discussion which details the extent to which the research question has been addressed, the limitations of the work and the degree to which it has been answered.

Le modèle RANS à une équation de fermeture est utilisée avec une nouvelle longueur de mélange. par interpolation, notre loi est universelle. Nous avons étendue ce résultat pour considérer les fonds rugueux. L'existence d'une solution au système d'équation associée est montrée, c'est un problème elliptique avec un terme source dans L¹. Nous utilisons le modèle "under location uncertainty" pour obtenir un profil de vitesse cohérent dans toute la couche limite turbulente. Le raisonnement que nous apportons ici lie un terme sous-grille à ce profile. Nous apportons également une estimation des variances à temps courts dans la zone visqueuse. / The RANS one-closure equation is tested with a new formulation of the turbulent mixing length.

Diretrizes para capacitação profissional por competências de trabalhadores da construção civil. / Guidelines of professional training of manpower of civil construction.Cláudio Barboza Ferreira Junior 27 October 2011 (has links)
O país está atravessando uma fase singular no setor da construção civil, particularmente no segmento de edificações. Entretanto, como consequência da queda de investimentos em capacitação de mão de obra nos últimos anos, a construção civil sofre pela escassez de profissionais especializados em quantidade e qualidade exigidas pelo setor. É neste contexto que se insere o presente trabalho, cujo foco é para a capacitação profissional em nível operacional, tendo como objetivo propor diretrizes para capacitação profissional por competência . Para alcançar o objetivo proposto, foi realizada uma revisão bibliográfica por meio de consultas a artigos técnicos nacionais e internacionais, dissertações e teses. Como resultado do trabalho, é proposto um modelo para programas de capacitação profissional por competências e uma proposta de aplicação para o caso do assentador e rejuntador de placas cerâmicas e porcelanato para revestimentos. / The country is undergoing a unique phase in the construction industry, particularly in the building segment. However, as a result of falling investments in manpower training in recent years, the construction industry faces a shortage of skilled professionals. In this context, our focus lies on professional training at the operational level, aiming to propose guidelines for professional training for competence, a large contingent of construction workers and in a short time. To achieve the proposed objective, a literature review was conducted through consultations with national and international technical articles, dissertations and theses. As a result of the work, a model is proposed for professional training programs concerning skills and an application proposal for the case of the fitting and reassembling of ceramic tiles and porcelain coating.

THE EFFECTS OF TEACHER IMPLEMENTATION OF DIFFERENTIAL REINFORCEMENT OF ALTERNATIVE BEHAVIOR IN INDIVIDUALS WITH AUTISM SPECTRUM DISORDERHitch, Elena J. 01 January 2019 (has links)
The purpose of this study was to evaluate the effects of a classroom teacher implementing trail-based functional analyses (FAs), experimentally evaluate the effects of a classroom teacher implementing differential reinforcement of alternative (DRA) procedures with participants diagnosed with autism spectrum disorder in the context of a natural setting, and assess the feasibility of the DRA for the classroom teacher. A multiple baseline with an embedded ABAB design was used for one participant and an ABAB design was used for the second participant to measure the percentage of the participants’ engagement in the alternative behavior and the target behavior. Results showed that the classroom teacher could implement the trail-based FAs with fidelity, DRA procedures were effective for both participants, and the teacher was neutral in regard to the feasibility of the procedures.
