Microfluidic devices for studying growth and detachment of Staphylococcus epidermidis biofilms.

Abstract: Microfluidic devices were used to study the influences of hydrodynamics of local microenvironments on Staphylococcus epidermidis (S. epidermidis) biofilm formation and the effects of a poly(β-1,6-N-acetyl glucosamine)-hydrolyzing enzyme (dispersin B) and/or an antibiotic (rifampicin) on the detachment of the biofilm. Elongated, monolayered biofilm morphologies were observed at high flow velocity and fluid shear locations whereas large clump-like, multilayered biofilm structures were produced at low flow velocity and fluid shear locations. Upon dispersin B treatment, most of the biofilm was detached from the microchannel surface. However, a trace amount of bacterial cells could not be removed from corner locations most likely due to the insufficient wall shear stress of the fluid at these locations. Dispersin B or rifampicin treatment was effective in delaying the dispersal behavior of bacterial cells, but could not completely remove the biofilm. Combined dynamic delivery of dispersin B and rifampicin was found to be effective for complete removal of the S. epidermidis biofilm.

The Sales Lead Black Hole: On Sales Reps' Follow-Up of Marketing Leads.

Abstract: The sales lead black hole—the 70% of leads generated by marketing departments that sales representatives do not pursue—may result from competing demands on sales reps' time. Using the motivation–opportunity–ability framework, the authors consider factors that influence sales reps' pursuit (or lack thereof) of marketing and self-generated leads. The proportion of time that sales reps devote to marketing leads depends on organizational lead prequalification and managerial tracking processes (extrinsic motivation), as well as marketing lead volume (opportunity), and sales rep experience and performance (ability). Consistent with a person–situation framework, individual sales rep factors should also moderate the influence of organizational processes on lead follow-up. Data from 461 sales reps employed by four firms confirm that as sales reps' experience increases, their responses to managerial tracking of lead follow-up and marketing lead volume decrease; responses to the quality of the lead prequali...
