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 of a matroid is a
generalization of the standard two-variable version, obtained by assigning a
separate variable to each element of the ground set . It encodes
the full structure of . Let \bv = \{v_e\}_{e\in E}, let be an
arbitrary field, and suppose is connected. We show that is
irreducible over K(\bv), and give three self-contained proofs that the Galois
group of over K(\bv) is the symmetric group of degree , where
is the rank of . 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. Substantial

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
hole and 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
