TL;DR: In this paper, the authors used the cultural, administrative, geographic, and economic distance framework proposed by Ghemawat to investigate the role of different distance factors on firms' foreign market acquisition behavior and examined the moderating role of market potential on the relationship between distance factors and target market selection.
Abstract: Purpose – The paper is in the domain of marketing strategies of multinational firms. Specifically, it aims to focus on target market selection of multinational firms.Design/methodology/approach – Using the cultural, administrative, geographic, and economic distance framework proposed by Ghemawat, the authors offer empirical support for the role of different distance factors on firms' foreign market acquisition behavior. In addition, they examine the moderating role of market potential of a target country on the relationship between distance factors and target market selection. The context of the paper is multinational firms from developing countries. The sample consists of cross‐border acquisitions (CBAs) completed by firms from 18 emerging countries between 1990 and 2006. The authors use ordinary least squares and moderated regression analysis to determine the main effect of distance factors and the interaction effect of market potential.Findings – The authors find that while cultural and geographic dist...

TL;DR: In this article, Bagheri et al. examined the role of inter-particle distance in the fracture toughness in rubber/micro void toughened epoxies and found that fracture toughness goes through a ductile-to-brittle transition.

TL;DR: In this article, a cavity shear layer, involving a downstream-travelling wave and associated vortex formation, its impingement upon the cavity corner, and upstream influence of this vortex-corner interaction are the subject of an experimental investigation.
Abstract: Oscillations of a cavity shear layer, involving a downstream-travelling wave and associated vortex formation, its impingement upon the cavity corner, and upstream influence of this vortex-corner interaction are the subject of this experimental investigation.Spectral analysis of the downstream-travelling wave reveals low-frequency components having substantial amplitudes relative to that of the fundamental (instability) frequency component; using bicoherence analysis it is shown that the lowest-frequency component can interact with the fundamental either to reinforce itself or to produce an additional (weaker) low-frequency component. In both cases, all frequency components exhibit an overall phase difference of almost 2kπ(k = 1, 2,…) between separation and impingement. Furthermore, the low-frequency and fundamental components have approximately the same amplitude growth rates and phase speeds; this suggests that the instability wave is amplitude-modulated at the low frequency, as confirmed by the form of instantaneous velocity traces.At the downstream corner of the cavity, successive vortices, arising from the amplified instability wave, undergo organized variations in (transverse) impingement location, producing a low-frequency component(s) of corner pressure. The spectral content and instantaneous trace of this impingement pressure are consistent with those of velocity fluctuations near the (upstream) shear-layer separation edge, giving evidence of the strong upstream influence of the corner region.

TL;DR: In this article, the optimum conditions for achieving dense and uniform microstructures by conventional ceramic processing are given in detail, and the SiC particles were found to strongly inhibit grain growth of the Al 2 O 3 matrix.
Abstract: Composites consisting of Al 2 O 3 + 5 vol.% 0·15 μm SiC particles were prepared by pressureless sintering. The optimum conditions for achieving dense and uniform microstructures by conventional ceramic processing are given in detail. The SiC particles were found to strongly inhibit grain growth of the Al 2 O 3 matrix. Densification was also significantly retarded by these ultra-fine particles, and possible explanations for this behavior are discussed.

TL;DR: The resonant optical response of a dense atomic potassium vapor under conditions such that the response is strongly influenced by local-field effects is studied.
Abstract: We have studied the resonant optical response of a dense atomic potassium vapor under conditions such that the response is strongly influenced by local-field effects. Our experimental results are in good agreement with the predictions of theory. We have also discovered a collision-induced shift of the potassium resonance lines given by \ensuremath{\Delta}${\mathrm{\ensuremath{\omega}}}_{\mathrm{c}\mathrm{o}\mathrm{l}=}$\ensuremath{\beta}N, where \ensuremath{\beta}=-5.0\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}8}$ ${\mathrm{sec}}^{\mathrm{\ensuremath{-}}1}$ ${\mathrm{cm}}^{3}$ for the 4 $^{2}$${\mathit{S}}_{1/2}$\ensuremath{\leftrightarrows}4 $^{2}$${\mathit{P}}_{1/2}$ transition and where \ensuremath{\beta}=-3.0\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}8}$ ${\mathrm{sec}}^{\mathrm{\ensuremath{-}}1}$ ${\mathrm{cm}}^{3}$ for the 4 $^{2}$${\mathit{S}}_{1/2}$\ensuremath{\leftrightarrows}4 $^{2}$${\mathit{S}}_{1/2}$\ensuremath{\leftrightarrows}4 $^{2}$${\mathit{P}}_{3/2}$ transition.
