[Review of the book \u3ci\u3eSustainable Prosperity in the New Economy? Business Organization and High-Tech Employment in the United States\u3c/i\u3e]

[Excerpt] Best known as a business and economic historian, William (Bill) Lazonick may often escape the view of academics in human resource studies, organizational behavior, and labor relations. This is a mistake. Lazonick\u27s new book, Sustainable Prosperity in the New Economy?, is a must-read for scholars and students in these fields. He has chosen to study an important problem in the real world, has marshaled detailed empirical evidence to support his argument, and has used this evidence to critique conventional theory in economics and management

Identification of joint parameters using FRF based decoupling

Structural and mechanical systems are assembled from smaller components using mechanical joints. The mechanical properties of the joints must be modeled in order to perform subsequent design and analysis of the structure or mechanical system. This study provides an analytical method of determining the parameters that describe the behavior of the joints using frequency response function (FRF) data that is measured at joint nodes. The variation in FRFs is derived by utilizing the consistent response conditions at the same joint nodes of the assembly system and the portioned subsystems. The variation reflects the mechanical properties of the joint and is utilized to extract the joint parameters. The validity of the proposed method is illustrated in two numerical applications
