Consistency of individual differences in several measures of Skinner box operant and other activity and their intercorrelations in 14 chinchilla bred rabbits were studied. Reliability analysis revealed that both operant and activity measures were highly consistent (Cronbach alpha>0.87) over at least 15 days. Furthermore, locomotor activity, the tendencies to press the lever with high frequency,...

Feeding behavior in Aplysia can be modified by operant conditioning in which contingent reinforcement is conveyed by the esophageal nerve (E n.). A neuronal analogue of this conditioning in the isolated buccal ganglia was developed by using stimulation of E n. as an analogue of contingent reinforcement. Previous studies indicated that E n. may release dopamine. We used a dopamine antagonist (me...

Encopresis or faecal soiling has been defined as an act of involuntary defecation which is not directly attributed to organic illness (Kanner, 1950). Encopresis or soiling may occur in children with normal intelligence, brain damaged children and psychotic children. It denotes an uncontrolled defecation of an emotional origin. Presently, there are few reports of successful treatment by means of...

Behavior-analytic terminology concerning the so-called inhibitory effect of operant antecedents lacks precision. The present paper describes the problem with current nomenclature concerning the effects of antecedent events that reduce operant responding and offers a solution to this problem. The solution consists of adopting a new term, abative, for the effect in question. This paper suggests t...

SIEGEL, J. M., M. B. STERMAN AND S. ROSS. Automatic detection and operant reinforcement of slow potential shifts.PHYSIOL. BEHAV. 23(2) 411-413, 1979.—A technique for the automatic detection and operant reinforcement of slow potential (SP) changes is described. The SP shift detection device contains 3 inhibit channels to control sources of potential artifact including: vertical EOG, horizontal E...

In this paper, we propose a framework to systematically analyze the structural form and thematic content of codes of ethics related to Information and Communication Technology (ICT codes of ethics). Then we apply this framework, within a sample of 30 organizations. Our purpose is to assess the organizational ethical positioning advocated by these ICT codes of ethics, using an adaptation of Kohl...

A key point in the CMD-problems is that the universe to be specified is not an example from a textbook but a piece of reality like a bank or an airport. In addition, the specification has to be somehow extracted from multiple, very informal and often hardly consistent descriptions provided by different people. Moreover, as the process of information system design is going on, and mutual underst...

Cassava mosaic disease (CMD) is the most widespread and economically important disease of cassava (Manihot esculenta Crantz) in tropical Africa. A disease of cassava was first described in East Africa in the nineteenth century (Warburg, 1894) and cassava mosaic, as it came to be called, was subsequently reported as spreading throughout the cassava-growing areas of Central and West Africa (Calve...
