AIDS-complex and our Leviathan. Can and should the state educate us about AIDS?

Sigusch pleads for removing AIDS education from the jurisdiction of the state. He reasons that as caretaker of citizens' sexual lives the state cannot avoid consolidating their status as its subjects.     

Differential Motivating Factors Among Intrapreneurial and Traditional Managers?: A Look At The Influence Of Reward Systems and Structures On Performance Among Intrapreneurial and Traditional Managers

ABSTRACT This paper examines the influence of rewards and structures on the performance of managers in positions defined as intrapreneurial and those defined as traditional managerial. Results indicated that financially oriented rewards and loosely coupled structures more strongly influenced the performance of intrapreneurial managers than the performance of traditional managers. The findings suggest that such measures may be key ingredients to enhance organizational environment.     

Ambiguity in 3-D patterns induced by lighting assumptions

A bistable pattern is shown with white and black bars with horizontal and vertical orientations which produce an impression of thin slabs stacked up in depth either toward or away from the observer. It is postulated that the ambiguity is induced by the observer's assumption of the direction of the light source.     

Perceptual learning in maze discriminations

In Experiment 1, rats were trained on a discrimination between rubber- and sandpaper-covered arms of a maze after one group had been pre-exposed to these intra-maze cues. Pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made easier by adding further discriminative stimuli, when it now significantly retarded learning. In Experiment 2, rats were trained on an extra-maze spatial discrimination, again after one group, but not another, had been pre-exposed to the extra-maze landmarks. Here too, pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made substantially easier by arranging that the two arms between which rats had to choose were always separated by 135°. The results of both experiments can be explained by supposing that perceptual learning depends on the presence of features common to S+ and S-.
