Matched-Filter Detection of Mode-Locked Laser Signals

The passive Fabry-Perot cavity is shown to be a good practical approach to the match-filter optimization for the sensitive detection of mode-locked laser signals. Doppler measurements of relative motion over a wide range of velocities are possible simply by measuring the cavity length for a peak output

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

On consecutive pattern-avoiding permutations of length 4, 5 and beyond

We review and extend what is known about the generating functions for consecutive pattern-avoiding permutations of length 4, 5 and beyond, and their asymptotic behaviour. There are respectively, seven length-4 and twenty-five length-5 consecutive-Wilf classes. D-finite differential equations are known for the reciprocal of the exponential generating functions for four of the length-4 and eight of the length-5 classes. We give the solutions of some of these ODEs. An unsolved functional equation is known for one more class of length-4, length-5 and beyond. We give the solution of this functional equation, and use it to show that the solution is not D-finite. For three further length-5 c-Wilf classes we give recurrences for two and a differential-functional equation for a third. For a fourth class we find a new algebraic solution. We give a polynomial-time algorithm to generate the coefficients of the generating functions which is faster than existing algorithms, and use this to (a) calculate the asymptotics for all classes of length 4 and length 5 to significantly greater precision than previously, and (b) use these extended series to search, unsuccessfully, for D-finite solutions for the unsolved classes, leading us to conjecture that the solutions are not D-finite. We have also searched, unsuccessfully, for differentially algebraic solutions.Comment: 23 pages, 2 figures (update of references, plus web link to enumeration data). Minor update. Typos corrected.

Induced subarrays of Latin squares without repeated symbols

We show that for any Latin square L of order 2m, we can partition the rows and columns of L into pairs so that at most (m+3)/2 of the 2x2 subarrays induced contain a repeated symbol. We conjecture that any Latin square of order 2m (where m ≥ 2, with exactly five transposition class exceptions of order 6) has such a partition so that every 2x2 subarray induced contains no repeated symbol. We verify this conjecture by computer when m ≤ 4
