Corporate Compliance Issues in Managing Supply Chains in the Environmental-Friendly 21 st Century

Recent economic crisis has alerted citizens around the world about the behavioral patterns of corporations that were not in lined with the expectations of the local citizens. These events has re-emerged the global conversations of the responsibilities of corporations that are beyond the conventional wisdom of financial accomplishments. Traditionally, corporations have been in tuned with financial goals and awareness of necessity of Corporate Compliance efforts operationally along their Supply Chains. The recent addition of Social Responsibilities has certainly complicated corporate strategies in varied magnitude. At times, it introduced un- welcomed uncertainty in terms of expectations. The focus of this research is to investigate the first-step for corporations, the understanding of Corporate Social Responsibility expectations so as to allow corporations to refine their strategies so as to be in compliance along their supply chains with minimal additional resources. An empirical model for data collection from corporate practitioners will also be introduced

Strategic use of E-Commerce in the Transformation of the Publishing Industry

The intent of this paper is to explore the strategic use of e-commerce in the transformation of the publishing industry. The first section of the paper explores the strategic use of e-commerce in the transformation of the publishing industry from a single distribution channel mass producer of printed books to a multiple distribution channel that will include e-books and “print on demand” technologies. Emphasis is placed on management strategies in the use of new information technologies in the global marketplace. The second section of this paper discusses the shift of competitive power among the various tiers along the publishing industry supply chain including the current developments in electronic publishing from the vantage point of the stakeholders The implications and likely scenario awaiting the future business environment of the publishing industry is presented in the third section of this paper

Galois groups of multivariate Tutte polynomials

The multivariate Tutte polynomial $\hat Z_M$ of a matroid $M$ is a generalization of the standard two-variable version, obtained by assigning a separate variable $v_e$ to each element $e$ of the ground set $E$. It encodes the full structure of $M$. Let \bv = \{v_e\}_{e\in E}, let $K$ be an arbitrary field, and suppose $M$ is connected. We show that $\hat Z_M$ is irreducible over K(\bv), and give three self-contained proofs that the Galois group of $\hat Z_M$ over K(\bv) is the symmetric group of degree $n$, where $n$ is the rank of $M$. An immediate consequence of this result is that the Galois group of the multivariate Tutte polynomial of any matroid is a direct product of symmetric groups. Finally, we conjecture a similar result for the standard Tutte polynomial of a connected matroid.Comment: 8 pages, final version, to appear in J. Alg. Comb.

Doping evolution of spin and charge excitations in the Hubbard model

To shed light on how electronic correlations vary across the phase diagram of the cuprate superconductors, we examine the doping evolution of spin and charge excitations in the single-band Hubbard model using determinant quantum Monte Carlo (DQMC). In the single-particle response, we observe that the effects of correlations weaken rapidly with doping, such that one may expect the random phase approximation (RPA) to provide an adequate description of the two-particle response. In contrast, when compared to RPA, we find that significant residual correlations in the two-particle excitations persist up to $40\%$ hole and $15\%$ electron doping (the range of dopings achieved in the cuprates). These fundamental differences between the doping evolution of single- and multi-particle renormalizations show that conclusions drawn from single-particle processes cannot necessarily be applied to multi-particle excitations. Eventually, the system smoothly transitions via a momentum-dependent crossover into a weakly correlated metallic state where the spin and charge excitation spectra exhibit similar behavior and where RPA provides an adequate description.Comment: 5 pages, 4 figures, plus supplementary materia
