Paving the way for CRM success: The mediating role of knowledge management and organizational commitment

Customer relationship management (CRM) has become one of the most influential technologies in the world, and companies are increasingly implementing it to create value. However, despite significant investment in CRM technology infrastructure, empirical research offers inconsistent support for its positive impact on performance. This study develops and tests a research model analyzing the process through which CRM technology infrastructure translates into organizational performance, drawing on the resource-based view (RBV) and the knowledge-based view (KBV) of the firm. Based on an international sample of 125 hotels, the results suggest that organizational commitment and knowledge management fully mediate this process.     

聚丙烯纤维母粒着色生产技术

概述了聚丙烯母粒色纺的生产技术,提出了色母粒制备的质量要求:颜料粒径≤1.0μm,细且丝颜料粒径≤0.5μm;压力过滤值≤0.15MPa·cm~2/g;色母粒热稳定性280～300℃.色母粒的加入对纺丝工艺与产品质量指标有影响,喷丝板换板周期色纺丝约为本色纺的一半,纤维强力约降低10%.依据有关配色定律可优化配方工艺,降低成本,增加效益.

An Experimental Study of Fatigue Strength for Adhesively Bonded Tubular Single Lap Joints

In this paper, manufacturing technology of the tubular single lap adhesive joint was studied to obtain reliable and optimal joint quality. In addition, a surface preparation method and a bonding process for the joint were devised. The effect of the adhesive thickness and the adherend roughness on the fatigue strength of the joint was experimentally investigated. From experiments, it has been found that the fatigue strength of the joint increased as the adhesive thickness decreased and the optimal arithmetic surface roughness of the adherends was about 2 μm.
