Rationality, traditionalism and the state of corporate governance mechanisms: illustrations from a less developed country
Purpose ? The purpose of this research is to provide an account of corporate governance practices in Bangladesh. This paper demonstrates that the traditionalist culture mediates the rationalist/legalist framework of corporate governance in Bangladesh. Design/methodology/approach ? A series of semi-structured interviews were conducted. Observations and the personal working experience of one of the researchers, along with documentation, provided rich sources of information for the paper. Findings ? The findings show that families have a dominant presence in all aspects of corporate governance. Boards of directors in companies play a significant part in serving the interests of families rather than those of general shareholders. Research limitations/implications ? This study focuses on corporate governance practices in a traditional setting and shows how traditional culture and values are in conflict with the rational ideas imported from a different setting. It suggests that the World Bank?s expectations that Anglo-American models of corporate governance will be effective in Bangladesh and possibly other LDCs are unfounded. Originality/value ? The paper adds to the literature on corporate governance, especially in the context of LDCs. It will be of great value to researchers and practitioners seeking to gain a better understanding of corporate governance frameworks in various settings
SUSY effects on the exclusive semi-leptonic decays and
In this paper we study the polarization asymmetries of the final state lepton
in the radiative dileptonic decay of B meson (\bsllg) in the framework of
Minimal Supersymmetric Standard Model (MSSM) and various other unified models
within the framework of MSSM e.g. mSUGRA, SUGRA (where condition of
universality of scalar masses is relaxed) etc. Lepton polarization, in addition
of having a longitudinal component (\pl), can have two other components, \pt
and \pn, lying in and perpendicular to the decay plane, which are proportional
to \ml and hence are significant for final state being or
. We analyse the dependence of these polarization asymmetries
on the parameters of the various models.Comment: version accepted for publication in Phys. Rev. D. Few refrences and

Regular and Singular Pulse and Front Solutions and Possible Isochronous Behavior in the Short-Pulse Equation: Phase-Plane, Multi-Infinite Series and Variational Approaches
In this paper we employ three recent analytical approaches to investigate the
possible classes of traveling wave solutions of some members of a family of
so-called short-pulse equations (SPE). A recent, novel application of
phase-plane analysis is first employed to show the existence of breaking kink
wave solutions in certain parameter regimes. Secondly, smooth traveling waves
are derived using a recent technique to derive convergent multi-infinite series
solutions for the homoclinic (heteroclinic) orbits of the traveling-wave
equations for the SPE equation, as well as for its generalized version with
arbitrary coefficients. These correspond to pulse (kink or shock) solutions
respectively of the original PDEs.
Unlike the majority of unaccelerated convergent series, high accuracy is
attained with relatively few terms. And finally, variational methods are
employed to generate families of both regular and embedded solitary wave
solutions for the SPE PDE. The technique for obtaining the embedded solitons
incorporates several recent generalizations of the usual variational technique
and it is thus topical in itself. One unusual feature of the solitary waves
derived here is that we are able to obtain them in analytical form (within the
assumed ansatz for the trial functions). Thus, a direct error analysis is
performed, showing the accuracy of the resulting solitary waves. Given the
importance of solitary wave solutions in wave dynamics and information
propagation in nonlinear PDEs, as well as the fact that not much is known about
solutions of the family of generalized SPE equations considered here, the
results obtained are both new and timely.Comment: accepted for publication in Communications in Nonlinear Science and

A proposal on leveraging workflow technology for building process aware visual analytics system.
Workflow analysis, conducted using both cognitive workflows and process workflows, has been employed to build and improve visual analytics systems. However, workflows and the visual analytics system have to date remained computationally separate. In this paper, we propose that workflow technology be leveraged to create process aware visual analytics systems. We argue that a process aware visual analytics system would be better able to support users, collect provenance information on user activity and track user decision pathways. This will enable visual analytics systems to become process
