A Two-level Method for Building a Statistical Shape Atlas

A statistical anatomic atlas has many applications, such as visualizing and analyzing the inner anatomic structures, 2D-3D and 3D-3D registration, registration-based segmentation, surgical planning and navigation. Due to genetic, sex and life-style factors, there are inherent nonpathological differences in the appearance and location of anatomic structures betwee

A new perspective on the integration-responsiveness pressures confronting multinational firms

The Integration-Responsiveness framework of Prahalad and Doz (1987) has been used extensively in the international business literature to typify the diverse and often-conflicting environmental pressures confronting firms as they expand worldwide. Although the IR framework has been successfully applied for over a decade, many theoretical and empirical studies have focused on the consequences of these pressures rather than the pressures themselves. Prahalad and Doz identified the economic, technological, political, customer and competitive factors that create the global integration and local responsiveness pressures on the diverse businesses and functions in MNEs. This article explains the methodology, including the procedure for data collection and analysis. The researchers conclude with a discussion of their findings and directions for future research, speculating as to the appropriate definition of the domain of IR pressures and the criteria they might use to validate measures of these
