1. Effect of Different Fiber Reinforcement Strategies on the Fracture Strength of Composite Resin Restored Endodontically Treated Premolars
Abstract Objective: To compare the effect of three different fiber reinforcement strategies on the fracture strength of composite resin restored endodontically treated premolars. Material and Methods: Seventy-two sound human premolars extracted for orthodontic reasons were divided into 6 groups (n=12) after endodontic treatment. Group 1: intact teeth (posi

2. Bond strength values of fiberglass post to flared root canals reinforced with different materials
Abstract The aim of this study was to compare in vitro the bond strength (BS) between fiberglass posts and flared root canals reinforced with different materials. The roots of 48 premolars were endodontically treated. After one week, the root canals were prepared to simulate an oversized root canal, except for the positive control group (PCG), which was ceme

4. Desamparo aprendido e imunização em humanos: avaliação metodológica/conceitual e uma proposta experimental / Learned helplessness and immunization in humans: methodological/conceptual evaluation and an experimental proposal
The results of learned helplessness studies with humans have been inconsistent. This is probably due to the systematic contiguity between the end of the aversive stimulus and the immediately preceding response during the uncontrollability session, which mimics an accidental control condition. Three experiments were conducted to establish a procedure with ade

7. Variabilidade induzida e operante sob contingências de reforçamento negativo / Induced and operant variability under negative reinforcement contingences
A variabilidade comportamental pode ser induzida por reforçamento parcial ou extinção, assim como pode ser reforçada diferencialmente. O objetivo deste estudo foi verificar como a variabilidade comportamental pode ser influenciada por estímulos aversivos, tanto no processo de indução por reforçamento parcial e extinção, como no reforçamento negati

8. Análise de eventos privados do tipo sentir sob controle de contingências programadas em um software. / Analysis of private events (fellings) under control of programmed contingencies in a software
Behavior Analysts have appointed relations between contingencies of reinforcement, corporeal conditions (private events), and public events. The aim of this experiment was to investigate the control of programmed contingencies on private events (fellings), using a procedure that caused those events and evoked the tact of them (feelings). Twenty students exec

9. Investigação longitudinal dos efeitos de diferentes contingências com estímulos apetitivos e aversivos sobre o desamparo aprendido / Longitudinal research on the effects of different contingencies with appetitive and aversive stimuli upon learned helplessness
The learned helplessness hypothesis was put forward by Seligman &Maier in 1976 under the assumption of generality among all stimulus conditions, aversive or otherwise, and as an explanatory model of human depression. This proposition allowed for some experimental manipulations aimed at reversing the effect, using, among others things, positive reinforcement
