The Cost

This article presents a rudimentary model of collaboration with the aim to understand the conditions under which groups of scientists will endogenously form optimal collaborative groups. By analyzing the model with computer simulations, I uncover three lessons for collaborative groups. First, in reducing the cost borne by scientists from collaborating, one benefits the members of the group. Second, increasing the number of potential collaborative partners benefits all those involved in a collaborative group. Finally and counter intuitively, this model suggests that groups do better when scientists avoid experimenting with new collaborative interactions.

The transperitoneal transport of macromolecules is dependent on both effective peritoneal surface area and intrinsic permeability of the peritoneum. For passage of small solutes, the effective surface area is the main determinant. We hypothesized that day-to-day variations in peritoneal clearances are caused by changes in the effective surface area and not in the intrinsic permeability. Four CAPD {continuous ambulatory peritoneal dialysis) patients without peritonitis were investigated on 28 consecutive days. Concentrations of beta-2-microglobulin, albumin, IgG, and alpha-2-macroglobulin were determined daily in dialysate {night bags) and weekly in serum. Clearances and their coefficients of variation were calculated. Mean coefficients of the intraindividual variation of protein clearances increased, the higher the molecular weight: they ranged from 12% for beta-2microglobulin clearance to 22% for alpha-2-macroglobulin clearance. Correlations were present between the clearances of albumin, IgG, and alpha-2-macroglobulin, but not between any of these and beta-2-microglobulin clearance. In all patients, protein clearance {C) was a power function of the free diffusion coefficient in water {D) according to the equation: C=a. Db in which b represents the restriction coefficient of the peritoneum, and thus intrinsic permeability. The coefficient of variation of the restriction coefficient was low (range 4–6%). This supports our assumption that the intrinsic permeability is fairly constant on the short term. Day-to-day variations in protein clearances are thus mainly caused by alterations in the effective peritoneal surface area. Longterm follow-up of the restriction coefficient in individual patients might identify those at risk for the development of structural changes in the peritoneal membrane.

Gender Balance

Recent studies identify gendered differences in communication and collaboration styles which suggest consequences for professional writing classrooms. If, indeed, men tend to stereotype women as clerks, prefer hierarchical collaboration, and value product over process, and, too, if gendered differences tend to increase counterproductive dissent, then the gender balance of writing groups might affect their dominant styles in those respects. However, when I analyzed the behaviors of over sixty student groups in my professional writing classes, I did not find gender balancing to have such effects. Instead, however, I observed other gender-related effects on collaboration: tendencies to stereotype men as technical experts and to self-segregate into gendered working teams. These findings suggest new perspectives on the role of gender for collaborative groups in professional writing classrooms.
