ABSTR1CT Resistive interchange instabilities in cylindrical plasmas are studied r including the effects of electron diamagnetic drift, perpendicular resistivity, and plasma compression. The analyses are pertinent to the seraicollisional regime where the effective ion gyro-radius is larger than the resistive layer width. Both analytical and numerical results show that the modes can be completely stabilized by the perpendicular plasma transport. Ion sound effects, meanwhile, are found to be
