Managerial coordination challenges in the alignment of capabilities and new subsidiary charters in MNEs
Subsidiary-level change requires the alignment of subsidiary charters and capabilities. Yet, the mechanisms through which the alignment of charters and capabilities unfolds are not yet well understood. In this paper, we investigate alignment from the perspective of managerial coordination. Drawing on a longitudinal study of a global IT firm, we identify three coordination mechanisms (charter-, experience-, and interaction-based coordination). By tracing the shifts in these coordination mechanisms over time and by specifying the implications of each mechanism for capability level change, we explain how managerial coordination influences alignment via subsidiary level capability change as well as alignment via the potential renegotiation of charters. This also allows us to provide new insights into situations of misalignment by explaining that particular mechanisms of coordination may become a source of decoupling between subsidiary actions and HQ mandates and may also result in capability level inertia. Moreover, while prior research has already acknowledged the role of interaction-based coordination for capability level change we show how and why such a mechanism of coordination emerges.

On the Finite Energy Weak Solutions to a System in Quantum Fluid Dynamics
In this paper we consider the global existence of weak solutions to a class
of Quantum Hydrodynamics (QHD) systems with initial data, arbitrarily large in
the energy norm. These type of models, initially proposed by Madelung, have
been extensively used in Physics to investigate Supefluidity and
Superconductivity phenomena and more recently in the modeling of semiconductor
devices . Our approach is based on various tools, namely the wave functions
polar decomposition, the construction of approximate solution via a fractional
steps method, which iterates a Schr\"odinger Madelung picture with a suitable
wave function updating mechanism. Therefore several \emph{a priori} bounds of
energy, dispersive and local smoothing type allow us to prove the compactness
of the approximating sequences. No uniqueness result is provided
Analysis of Oscillations and Defect Measures for the Quasineutral Limit in Plasma Physics
We perform a rigorous analysis of the quasineutral limit for a hydrodynamical
model of a viscous plasma represented by the Navier Stokes Poisson system in
. We show that as the velocity field strongly
converges towards an incompressible velocity vector field and the density
fluctuation weakly converges to zero. In general the limit
velocity field cannot be expected to satisfy the incompressible Navier Stokes
equation, indeed the presence of high frequency oscillations strongly affects
the quadratic nonlinearities and we have to take care of self interacting wave
packets. We shall provide a detailed mathematical description of the
convergence process by using microlocal defect measures and by developing an
explicit correctors analysis. Moreover we will be able to identify an explicit
pseudo parabolic pde satisfied by the leading correctors terms. Our results
include all the previous results in literature, in particular we show that the
formal limit holds rigorously in the case of well prepared data.Comment: Submitted pape
Acceptance and Use of E-Learning Based on Cloud Computing: The Role of Consumer Innovativeness
Cloud computing and E-learning are the inevitable trend of computational science in general, and information systems and technologies in specific.However, there are not many studies on the adoption of cloud-based E-learning systems. Moreover, while there are many papers on information system adoption as well as customer innovativeness, the innovativeness and adoption in the same model seems to be rare in the literature. The study combines the extended
Unified Theory of Acceptance and Use of Technology (UTAUT2) and consumer innovativeness on the adoption of E-learning systems based on cloud computing. A survey was conducted among 282 cloud-based E-learning participants and analyzed by structural equation modeling (SEM). The findings indicate that the adoption of cloud-based E-learning is influenced by performance expectancy, social influence, hedonic motivation, and habit. Interestingly, although innovativeness is not significant to use intention, it has a positive effect on E-learning usage which is relatively new in Vietnam
