This paper has examined the phenomenon of convergence of per capita out put levels across the IC countries for the 1960-1998 periods. Three concepts of convergence, i.e., sigma beta and relative beta, have been used. The estimated beta values reveals only a very weak convergence (?=.0014) across IC for 1960-1998 period. But when a more homogeneous group of countries were selected, the results s...

A large literature documents declining measures of business dynamism including high-growth young firm activity and job reallocation. A distinct literature describes a slowdown in the pace of aggregate labor productivity growth. We relate these patterns by studying changes in productivity growth from the late 1990s to the mid 2000s using firm-level data. We find that diminished allocative effici...

BACKGROUND Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension. This may not represent either the axis or the extent of dynamism through the entire cardiac cycle. In this study, we used real-time 3D transesophageal echocardiography (TEE) to analyze geometric changes in multiple...

In this paper, a two-phase model of air shock wave induced by rock-fall was described. The model was made up of the uniform motion phase (velocity was close to 0 m·s-1) and the acceleration movement phase. The uniform motion phase was determined by experience, meanwhile the acceleration movement phase was derived by the theoretical analysis.A series of experiments were performed to verify the t...

durability as continuity of identity and dynamism as changing and adaptability to new conditions are important architectural discussions. this paper aims to define the concepts and positions of durability and dynamism in the architectural structure. it seems that it is important to discuss which relations and components of an architectural structure have more effective roles in supporting ident...
