1. Concrete block structural masonry beam shear design: theoretical and experimental analysis and recommendations to the brazilian standards
Resumo Vigas são submetidas à flexão e cisalhamento, sendo esse último esforço o tema desta pesquisa. O objetivo deste trabalho é analisar especificações para dimensionamento ao esforço cortante de vigas de alvenaria estrutural em blocos de concreto, a partir de extensa avaliação da literatura e de ensaios experimentais aqui relatados. A partir de

2. Learning processes and the neural analysis of conditioning
Classical and operant conditioning principles, such as the behavioral discrepancy-derived assumption that reinforcement always selects antecedent stimulus and response relations, have been studied at the neural level, mainly by observing the strengthening of neuronal responses or synaptic connections. A review of the literature on the neural basis of behavio

3. Behavior analysis of the cue-induced animal model of relapse / Análise comportamental do modelo animal de recaída cue-induced
A recaída ao uso de drogas é um dos principais obstáculos para o tratamento do adicto. Um dos modelos animais mais utilizados para estudar a recaída no laboratório é o chamado de cue-induced. Embora esse modelo tenha se mostrado útil para o estudo de processos neurofisiológicos envolvidos na recaída, seu valor para a análise do controle de estímul

4. Operação estabelecedora condicionada substituta: uma demonstração experimental / Surrogate conditioned establishing operation: an experimental demonstration
Establishing operations (EO`s) are environmental events defined by two of their effects: establishing the effect of a consequence as a reinforcement or a punisher and altering the frequency of any response that, in the past, was related to it. The EO`s are divided in unconditioned and conditioned, being the last ones classified in three different types: surr

5. The effects of different durations of light on the response acquisition and maintenance of lever press with delayed reinforcement / O efeito de diferentes durações de luz sobre a aquisição e manutenção da resposta de pressão à barra com atraso de reforço
Quinze ratos foram distribuídos em cinco grupos com o objetivo de avaliar os efeitos de diferentes durações de luz, que eram apresentadas durante o período de atraso, sobre a aquisição e manutenção da resposta de pressão à barra com atraso de reforço, sem modelagem dessa resposta. O estudo foi dividido em duas fases com dezessete sessões cada (qu

6. What controls verbal responses emitted when a give behavior is observed / O que controlaria respostas verbais diante de um comportamento observado
The tact is a verbal operant in which the response is emitted under control of an antecedent non-verbal stimulus and is maintained by generalized conditioned reinforcement. Technically, a verbal report and an explanation can be considered tacts. Among the tacts one emits, those in which the speaker behaves verbally under the control of another persons behavi

7. Efeito da pré-exposição a dietilpropiona e a cafeína sobre o valor reforçador da dietilpropiona / Effect of pre-exposure to diethylpropion or caffeine on the reinforcing value of diethylpropion
Recent literature considers sensitization resulting from pre-exposure to psychostimulants as a possible factor in drug addiction acquisition, maintenance and relapse. The aim of this study was to verify if pre-exposure to the psychostimulants diethylpropion (DEP) and caffeine (DEP) would sensitize rats to the reinforcing value of DEP. Four experiments were c

8. A negação da diferença: um estudo sobre as interações de alunos com deficiência visual na escola pública
This study searches to understand how the interactions of students with visual handicaps take place at school. It is an empiricist inquiry which describes and analyses these students s experience of schooling at a public school in Salvador, Bahia. Considering that the current pedagogic discourse in Brazil appeals to a perspective of housing the differences,

9. A influÃncia da teoria do consenso na justiÃa penal: o advento da Lei 9.099/95 como consequÃncia da adoÃÃo da justiÃa consensual no Direito Penal Brasileiro
The current dissertation consists in an attempt of demonstrating that, in the Democratic State of Right, model adopted in our country in this historical moment, the consensus theorie permeate the inter-personal relations. In this context, starting from the thoughts of Beccaria, Rawls, Habermas, Roxin, among others, we try to examine, under a constitutional p

10. Efeitos da fluoxetina sobre a eficácia de reforçadores condicionados / Effects of fluoxetine on the effectiveness of conditioned reinforcers
Depression, as seen by the Experimental Analysis of Behavior, has been related to reinforcement rate, establishing operations and decreased sensitivity to positive reinforcers. The biobehavioral approach to reinforcement has implicated the dopaminergic system (DA), in the neural basis of reinforcement. Also DA agents have been demonstrated to change the effe

11. Condicionamento operante e manutenção da resposta de bicar o disco em esquemas de reforçamento continuo por pombos (Columba livia) submetidos a ablação das estruturas telencefalicas
This work analysed in two experiments the learning and the retention of the learning of the relationship between key-pecking and food in pigeons who had suffered the ablation of the telencephalic structural (thalamic pigeons). There have been used nine adult pigeons (Columba livia) maintained at 80% of its ad libitum weight. The experiment I analysed the per

12. Rate Of Conditioned Reinforcement Affects Observing Rate But Not Resistance To Change
The effects of rate of conditioned reinforcement on the resistance to change of operant behavior have not been examined. In addition, the effects of rate of conditioned reinforcement on the rate of observing have not been adequately examined. In two experiments, a multiple schedule of observing-response procedures was used to examine the effects of rate of c
