This paper introduces an Intelligent Computer Assisted Language Learning system designed to provide reading input for language learners based on the syntactic complexity of their language production. The system analyzes the linguistic complexity of texts produced by the user and of texts in a pedagogic target language corpus to identify texts that are well-suited to foster acquisition. These te...

A peptide hormone, root meristem growth factor (RGF), regulates root meristem development through the PLETHORA (PLT) stem cell transcription factor pathway, but it remains to be uncovered how extracellular RGF signals are transduced to the nucleus. Here we identified, using a combination of a custom-made receptor kinase (RK) expression library and exhaustive photoaffinity labeling, three leucin...

The purpose of this study was to systematically map the forelimb area of primary motor cortex (M1) in rhesus macaques in an effort to investigate further the organization of motor output to distal and proximal muscles. We used stimulus-triggered averaging (StTAing) of electromyographic activity to map the cortical representation of 24 simultaneously recorded forelimb muscles. StTAs were obtaine...

The seventh international seminar on Vygotsky held in Geneva discussed a new French language translation of texts from ‘pedology,’ the now largely lost Soviet science developing child. In this introduction, guest editors touch three concepts development which coincide with elements Vygotsky’s best known idea, Zoped, or zone proximal development. each case, we find that pedological has potential...

Vygotskij’s educational concept of the Zone of Proximal Development (ZPD) calls for an adaptation of learning activities to the present state of learner’s knowledge and abilities. At the same time, Vygotskij’s educational model includes a strong bent towards social and collaborative learning. In practice, a tight integration between personalized and collaborative learning is called for. Along t...
