On the shear rate dependence of red cell aggregation in vitro.

Non-Newtonian viscosity of blood, i.e., the rise in apparent viscosity at low flow, was believed to be a result of reversible aggregation of red cells at low velocity gradients (shear rate). By making a cone-plate viscometer transparent, direct observation was made possible of the blood flowing under defined shear rates. Red cell aggregates, occurring in all cases at low flow, were reversibly dispersed by increasing the shear rate. This behavior was independent of the addition of anticoagulants, but it could be altered by changing the plasma protein composition. Red cells in serum did not form aggregates; such nonaggregating samples did show an increase in viscosity at low shear rates. Since the sedimentation rate can be influenced by many parameters, it is not reliable in describing red cell aggregation. Aggregation of red cells is linked with a marked separation of plasma and cells. Such a separation is of considerable influence on cone-plate viscometry.

Higher education in retirement: The Institute for Retired Professionals.

This paper indicates the failure of our society to educate its citizens in the "worthy" use of retirement leisure. It contends that educated retirees should be offered an opportunity to function in creative, dignified and self-directed roles on university campuses. It describes the program of the Institute for Retired Professionals at The New School for Social Research in New York City, which has been functioning since 1962 and now serves as a model for a growing number of university programs for retirees. At the IRP educated retirees have found a new way of spending their retirement years in dignified roles as teachers, leaders, administrators and participants in their own inner university.

[Phsychotherapy results: What do our patients think?].

The present paper shows the way a mental health organization works and, at the same time, examines some results upon the post-therapy follow-up for outpatient treatments, the therapists' qualities perceived by the patients and the readmission rate. The results are twofold: for internal purposes, they allow a feedback for continuous quality improvement. For the outside, they generate information for future comparisons among other similar organizations. This paper also address the debate between two major stands in the field of psychotherapy research (one for the Evidence Based Psychotherapy and the other for the Psychotherapy Based on Common Features).
