Effects of S-(+)- and R-(-)-3,4,dimethoxyphenylisopropylamines in the rat.

Observational learning: a technique for elucidating S-R mediation processes.

Os watched naive models (Ms) perform at a visual discrimination avoidance task. In a 2 X 2 design, task apparatus for M was either in the same orientation or rotated relative to that subsequently used for O, and hand used by M was either the same or different from that later to be used by 0. Os' test data conformed in near detail to the prediction that positive transfer would be proportional to...

نگاشت های R - s - پیوسته

کلاس جدیدی از نگاشتهای پیوسته، به نام نگاشت های R - s - پیوسته ، معرفی میشود. ارتباط میان R - s - پیوستگی با پیوستگی و انواع دیگری ازپیوستگیهای قوی که تاکنون معرفی شده اند، بررسی میشود. سپس ویژگیهای نگاشتهای R - s - پیوسته مورد مطالعه قرار میگیرد.

(r,t)-injectivity in the category $S$-Act

In this paper, we show that injectivity with respect to the class $mathcal{D}$  of dense monomorphisms of an idempotent and weakly hereditary closure operator of an arbitrary category  well-behaves. Indeed, if $mathcal{M}$ is a subclass of monomorphisms, $mathcal{M}cap mathcal{D}$-injectivity  well-behaves. We also introduce the notion of $(r,t)$-injectivity in the category {bf S-Act}, where $r...
