Inconsistent findings about role stress and performance motivates this study. Data from 240 customer service representatives (CSRs) and 27 supervisors showed that role conflicts (involving supervisors and consumers) negatively relate to performance, while CSRs’ adaptive behavior mediates the relationship. CSRs’ feedback seeking moderates effects of role conflicts on adaptive behaviors.

The primary aim pursued by the preparation of separation membrane is the preparation of the membrane thin as well as with no defect. The field-flow fractionation deposition is a new molding technology which can overcome the traditional disadvantages such as multi-preparation to the preparation of great area of separation membrane with no defect. Therefor the mainly ingredients which influence the appearance and performance of titanium membrane layer are investigated by scanning electricity mirror (SEM) as well as porous material testing instrument: powder performance prepared and confected; selection of supporting body; sintering system such as temperature and time. It is shown that the membrane thickness can be controlled at or so; the filtration precision mainly rests with powder performance and selection of supporting body and little sintering system
