Feedback is a fundamental concept within the physical Feedback has also been a fundamental concept and the social sciences with its modern origins drawn throughout the history and development of cybernetics. from cybernetics. Information science is exploring feedThe concept of feedback have evolved from Wiener’s back as a key component in the interactive model of (1948, 1950/1954, 1953) cyberne...

This paper describes an experimental study of interactivity effects in electronically mediated feedback communication. Conversational interactivity is expected to be lower when pairs of subjects are using mixed communication media. Performance feedback is expected to be less successful when interactivity is reduced, especially when the properties of the communication environment violate the nor...

since the emergence of the process-oriented approach to second language writing instruction two main questions have been what and how error feedback should be given to the students. the question of whether teachers should provide feedback on grammar in the writing assignments of english as a foreign language students, and if so how, has been a matter of considerable debate in the field of secon...

In closed-loop systems, sensor feedback delays may have disastrous implications for performance and stability. Flies have evolved multiple specializations to reduce this latency, but the fastest feedback during flight involves a delay that is still significant on the timescale of body dynamics. We explored the effect of sensor delay on flight stability and performance for yaw turns using a dyna...

the present study-both qualitative and quantitative--explored fifty efl learners’ preferences for receiving error feedback on different grammatical units as well as their beliefs about teacher feedback strategies. the study also examined the effect of the students’ level of writing ability on their views about the importance of teacher feedback on different error types. data was gathered throug...

autoimmunity and viral infections are closely associated fields, and viruses have been proposed as a likely aetiological, contributory or triggering factors of systemic autoimmune diseases. hepatitis c virus seems to be the virus usually associated with the appearance of autoimmune diseases, and the relationship between chronic hepatitis c virus infection and some autoimmune disease has been st...

treatment of severe immune thrombocytopenic purpura (itp) accompanied by life-threatening bleeding events is challenging and a combination of treatment measures should be undertaken to rapidly increase the platelet count. herein, we report a case of severe itp in a seven-year-old boy who suffered from massive bleeding which was totally unresponsive to conventional therapeutic interventions. sin...
