Despite the methodological advantages of representative sampling, few researchers in the field of marital violence have employed random samples for laboratory assessments of couples. The current study tests the feasibility and sampling success of three recruitment methods: (a) random digit dialing, (b) directory-assisted recruitment, and (c) a hybrid method. The number of successful telephone contacts with couples does not differ across the three methods; most successful calls contact nonviolent couples. The sample recruited through all three methods does not appear to match the demographics of the calling area, and all methods require a high monetary and human resource investment. 相似文献

Research on innovation management and technology transfer in China is in its early stages and growing rapidly, as technology is transferred to Chinese organizations and the organizations themselves create innovations. The studies to date provide promising theoretical ideas, but specific findings should be regarded as tentative, due to the research designs and methods employed. As with early research on innovation in the West, it is likely that these early studies of innovation in China will have significant impact on innovation research and practice in the future, both in China and throughout the world. 相似文献
