    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

    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 μ+ μ\mu^+ ~ \mu^- or τ+τ˜\tau^+ \~\tau^-. 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 two tables adde

    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 Numerical Simulatio

    Proteomics in the Light of Integral Value Transformations

    In this paper, Proteomics have been studied in the light of Integral Value Transformations (IVTs) which was introduced by Sk. S. Hassan et al in 2010. For case study, a Human olfactory receptor OR1D2 protein sequence has been taken and then different IVTs have been used to evolve OR1D2 into some other proteomic like sequences. It has been observed that some of the generated sequences have been mapped to another olfactory receptor in Human or in some other species. Also it has been corroborated through fractal dimension that some of the fundamental protein properties have been nearly intact, even after the mapping. This study will help to comprehend the proteomic evolutionary network with the help of IVTs
