An overview of three decades of mergers and acquisitions research
Mergers and acquisitions (M&A) have long attracted managers’ attention and have been researched in different perspectives and using different theories. In this study we grasp the wealth of extant research in the field of M&As. We conducted a bibliometric study of 635 articles on strategic management and international business research published in 34 highly ranked management journals between 1983 and 2012. We performed citation, co-citation and factor analyses to uncover the issues examined by scholars, the main theoretical approaches and themes researched. The results show a relative shift from economic and financial approaches to knowledge-based and organizational learning perspectives in recent years. There was also an evolution from assessing the performance of firms after an M&A to seeking an understanding of what may drive synergy creation after the integration process. Furthermore we observed an increasing interest in cross-border M&As. We discuss our findings, identifying gaps and suggesting paths for future research.info:eu-repo/semantics/publishedVersio
Can the meson cloud explain the nucleon strangeness?
We use the meson cloud model, including the kaon and the contributions,
to estimate the electric and magnetic strange form factors of the nucleon. We
compare our results with the recent measurements of the strange quark
contribution to parity-violating asymmetries in the forward G0 electron-proton
scattering experiment. We conclude that it is not possible to explain the data
using this model.Comment: version accepted for publication in Phys. Rev.
Bifurcation Analysis of the Watt Governor System
This paper pursues the study carried out by the authors in {\it Stability and
Hopf bifurcation in the Watt governor system} \cite{smb}, focusing on the
codimension one Hopf bifurcations in the centrifugal Watt governor differential
system, as presented in Pontryagin's book {\it Ordinary Differential
Equations}, \cite{pon}. Here are studied the codimension two and three Hopf
bifurcations and the pertinent Lyapunov stability coefficients and bifurcation
diagrams, illustrating the number, types and positions of bifurcating small
amplitude periodic orbits, are determined. As a consequence it is found a
region in the space of parameters where an attracting periodic orbit coexists
with an attracting equilibrium.Comment: 34 pages, 9 figure
