1. Clinical correlates of pp65 antigenemia monitoring in the first months of post kidney transplant in patients undergoing universal prophylaxis or preemptive therapy
Abstract Introduction: Human cytomegalovirus is a major cause of morbidity in kidney transplant patients. Objectives: We aimed to study viral replication and serological response in the first months post kidney transplant in patients undergoing universal prophylaxis or preemptive therapy and correlate the findings with the clinical course of Human cytomega

2. 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

3. Contingência e contigüidade no responder de ratos submetidos a esquemas de razão e intervalo variáveis / Contingencies and contiguity imposition on response by exposing rats to variable interval and variable ratio schedule
The present study comprises two experiments (experiment 1 and experiment 2) that applied delayed reinforcement [non-resentting] procedure [schedule in which the second component operates on a fixed time condition (FT)]. The main purpose was to manipulate experimentally contingencies and contiguity relations by using different reinforcement schedules (respons

4. Um estudo sobre alterações ambientais independentes da resposta, comportamento supersticioso e desamparo aprendido
Sometimes environmental changes that follow responses are not produced by the responses themselves, such changes are response independent and the probability of their occurrence do not depend on the occurrence of a response. Two different fields of research have investigated the independent relation between the emission of responses by an organism and enviro

5. Religion as Schedule-Induced Behavior
In this article, I argue that a class of religious behaviors exists that is induced, for prepared organisms, by specific stimuli that are experienced according to a response-independent schedule. Like other schedule-induced behaviors, the members of this class serve as minimal units out of which functional behavior may arise. In this way, there exist two cla

6. Acquisition Of Cocaine Self-Administration With Unsignaled Delayed Reinforcement In Rhesus Monkeys
Six experimentally naive rhesus monkeys produced 0.01 mg/kg/infusion cocaine by lever pressing under a tandem fixed-ratio 1 differential-reinforcement-of-other-behavior schedule. One lever press initiated an unsignaled 15- or 30-s delay culminating in cocaine delivery. Each press made during the delay reset the delay interval. With two exceptions, respondi

7. Concurrent Second-Order Schedules: Some Effects Of Variations In Response Number And Duration
To examine the effects on concurrent performance of independent manipulations of response-unit duration and number, 6 hens were exposed to concurrent second-order schedules of reinforcement. Each first-order operant unit required completion of a fixed-ratio schedule within the time specified by a fixed-interval schedule, with one further response completing

8. Influences on Cocaine Tolerance Assessed under a Multiple Conjunctive Schedule of Reinforcement
Under multiple schedules of reinforcement, previous research has generally observed tolerance to the rate-decreasing effects of cocaine that has been dependent on schedule-parameter size in the context of fixed-ratio (FR) schedules, but not under the context of fixed-interval (FI) schedules of reinforcement. The current experiment examined the effects of coc

9. 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

10. Effect of 2',3'-didehydro-3'-deoxythymidine in an in vitro hollow-fiber pharmacodynamic model system correlates with results of dose-ranging clinical studies.
We sought to validate an in vitro system which could predict the minimal effect dose of antiretroviral agents. Mixtures of uninfected CEM cells and CEM cells chronically infected with human immunodeficiency virus (HIV) type 1 MN were exposed to 2',3'-didehydro-3'-deoxythymidine (D4T) in vitro in a hollow-fiber model which simulates the plasma concentration-t

11. Motivational Influences on Performance maintained by Food Reinforcement
In Study 1, we examined the independent effects of reinforcer consumption during sessions and meal consumption prior to sessions on performance maintained by food reinforcement. Nine individuals with developmental disabilities participated. On alternate days, a preferred edible item was delivered during (a) seven sessions conducted before lunch (repeated-rei
