Assessing the Barriers and Changes of Cross-Cultural Supervision: A Case Study

This article examines conflicts and communication problems that can occur in cross-cultural supervisory relationships when cultural issues are not addressed. Recommendations for cross-cultural supervision are discussed.     

Effects of PbO-B2O3-CuV2O6 glass on the microwave dielectric properties of （Pb0.5Ca0.5） （Fe0.5Nb0.5）O3 ceramics

The influences of the PbO-B2O3-CuV2O6 （PBC） additives on the microwave dielectric properties of （Pb0.5Ca0.5） （Fe0.5Nb0.5）O3 （PCFN） ceramics were investigated as a function of sintering temperature from 950 ℃ to 1 100 ℃. The sintering temperature of the specimens with the glass could be lowered from 1125 ℃ to 1 025℃ without the degradation of microwave dielectric properties. The microwave results showed that the dielectric constant cr was not significantly different while Qf values decreased with the increase of CuV206 content of PBC glass. For the specimens doped with PB-CV0.1 glass （81% PbO-9% B203-10% CuV2O6） and sintered at 1 025 ℃ for 3 h, the microwave dielectric properties of Qf=4 823 GHz, Cr=107.1 with TCF=＋15.03 ×10^-6/℃ were obtained.
