DEFINING QUALITY: ALTERNATIVES AND IMPLICATIONS
梳理了质量定义的演变，指出不存在普适定义，不同情境适用不同定义，并讨论了选择不同定义对研究的影响。
The search for a universal definition of quality has yielded inconsistent results. Such a global definition does not exist; rather, different definitions of quality are appropriate under different circumstances. In this article, we trace the evolution of quality definitions and describe the trade-offs inherent in accepting one definition of quality over another. The implications of using various definitions of quality in future research also are discussed.
