A note on linearized "New Massive Gravity" in arbitrary dimensions
By means of a triple master action we deduce here a linearized version of the
"New Massive Gravity" (NMG) in arbitrary dimensions. The theory contains a
4th-order and a 2nd-order term in derivatives. The 4th-order term is invariant
under a generalized Weyl symmetry. The action is formulated in terms of a
traceless mixed symmetry tensor
and corresponds to the massive
Fierz-Pauli action with the replacement
e_{\mu\nu}=\p^{\rho}\Omega_{\mu\nu\rho}. The linearized 3D and 4D NMG
theories are recovered via the invertible maps and respectively.
The properties and follow
from the traceless restriction. The equations of motion of the linearized NMG
theory can be written as zero "curvature" conditions \p_{\nu}T_{\rho\mu} -
\p_{\rho}T_{\nu\mu}=0 in arbitrary dimensions.Comment: 15 pages, no figures, few typos fixed, one more referenc
Hamilton-Jacobi Approach for Power-Law Potentials
The classical and relativistic Hamilton-Jacobi approach is applied to the
one-dimensional homogeneous potential, , where and
are continuously varying parameters. In the non-relativistic case, the
exact analytical solution is determined in terms of , and the total
energy . It is also shown that the non-linear equation of motion can be
linearized by constructing a hypergeometric differential equation for the
inverse problem . A variable transformation reducing the general problem
to that one of a particle subjected to a linear force is also established. For
any value of , it leads to a simple harmonic oscillator if , an
"anti-oscillator" if , or a free particle if E=0. However, such a
reduction is not possible in the relativistic case. For a bounded relativistic
motion, the first order correction to the period is determined for any value of
. For , it is found that the correction is just twice that one
deduced for the simple harmonic oscillator (), and does not depend on the
specific value of .Comment: 12 pages, Late
Just Markets from the Perspective of Catholic Social Teaching
The justice of markets is intricately connected to the treatment of the poor and the disadvantaged in market economies. The increased interest of multinational corporations in low-income market segments affords, on one hand, the opportunity for a more inclusive capitalism, and on the other, the threat of greater exploitation of poor and disadvantaged consumers. This article traces the contributions of Catholic Social Teaching and its basic principles toward providing insight into what constitutes justice in such marketing to the impoverished situations
The Integrative Justice Model for Marketing to the Poor: An Extension of S-D Logic to Distributive Justice and Macromarketing
As multinational corporations (MNCs) increasingly turn their attention to the fast growing markets of China, India, Brazil, and other developing areas, the question of fair treatment of consumers and other residents of those areas is more intensively debated than ever before. In essence, issues of distributive justice come to the fore, that is, are the benefits and burdens of rapid economic development being fairly allocated among the parties and stakeholders to the expanded economic transactions? In response to this question, the authors have postulated a detailed normative model for ethically marketing to impoverished consumer segments; they label their model, the Integrative Justice Model (IJM) for impoverished markets. In this article, the authors show how the IJM, an independently derived model of normative marketing, conforms in its key operational elements to the foundational premises (FPs) of the positive S-D logic and extends the S-D logic perspective to societal and ethical concerns. Furthermore, the authors connect the S-D logic philosophy to macromarketing frameworks such as distributive justice, sustainability, and labor
Marketing to the Poor: An Integrative Justice Model for Engaging Impoverished Marketing Segments
The relatively recent entry of multinational corporations (MNCs) into low-income markets, particularly in developing countries, affords the opportunity for the more inclusive capitalism envisioned by globalists. Alternatively, an expansion of MNC marketing in less developed economies might foreshadow the greater exploitation of disadvantaged consumers predicted by many critics of expanded free trade. To diffuse the charge of “exploitative” marketing, it is imperative that corporate marketing efforts seeking to engage impoverished segments be grounded in a strong ethical framework. This article unveils one such framework—the “integrative justice model” (IJM). The IJM is an aspirational model that outlines how to market ethically to disadvantaged consumers in both developed and developing countries. The authors derive the elements of this model from frameworks of moral philosophy and management theory. Although the IJM is normative in nature, the authors connect it to real-world examples, which provides MNCs that market to the poor practical benchmarks for conducting their business operations with fairness and equity. The article concludes with a discussion of the implications of the IJM for public policy
Gross National Happiness (GNH): Linkages to and Implications for Macromarketing
This theoretical commentary explores the concept of Gross National Happiness (GNH) and connects it with several central macromarketing concepts such as QoL, ethics, the common good, the purpose of market activity as well as the United Nations’ Sustainable Development Goals. The paper portrays GNH as a normative concept that captures collective well-being; it categorizes GNH, at least from the standpoint of Western moral philosophy, as most closely aligned with classical utilitarianism, and it distinguishes GNH from QoL on the basis of its predominantly aspirational and subjective orientation. It asserts that GNH can be seen as one manifestation of the common good, and, in that manner can be perceived as a ‘more ethical’ conception of the purpose of business activity. Finally, it links GNH to promising areas of Macromarketing scholarship. One essential contribution of this commentary is that it differentiates subjective community happiness from more objective measures of QoL familiar to macromarketing studies
