The spatial dynamics of the optical emission from an array of 50 times 50 individual microcavity plasma devices is investigated. The array is operated in argon and argon-neon mixtures close to atmospheric pressure with an ac voltage. The optical emission is analysed with phase and space resolution. It has been found that the emission is not continuous over the entire ac period, but occurs once per half period. Each of the observed emission phases shows a self-pulsing of the discharge, with (...) several bursts of emission of fixed width and repetition rate. The number of emission bursts depends on applied voltage and frequency. Spatially resolved measurements prove that the emission bursts are formed by overlapping emission pulses from single discharge cavities. Intensity differences between positive and negative half-wave can be interpreted through spatially resolved measurements of single discharge cavities. (shrink)

Contractualism is one of the most promising ‘centers of gravity’ in business ethics. In this guest editorial we provide a concise roadmap to the field, sketching contractualism’s historic and disciplinary antecedents, the basic argumentative structure of the contract model, and its boundary conditions. We also sketch two main dimensions along which contributions to the contractualist tradition can be positioned. The first dimension entails positive versus normative theorizing – does a given contribution analyze the world as it is or how it (...) ought to be? The second dimension involves four different levels of analysis that are commonly employed in contractualist business ethics: the nano, micro, meso, and macro levels. We then proceed to position the articles comprising this special issue along these two dimensions. (shrink)

Many of the most serious crimes that fall within the justificatory scope of the harm principle do so constitutively. They do so in the sense that the harm that the crime is designed to prevent is a...

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

This book brings together both new and previously published essays on the Greek political history of the fifth century BC and historiography. It examines the relationship between philosophy and social/political conditions, and includes a new analysis of Aristotle's views on slavery and a discussion of the practicality of Plato's political theories.

In recent years attention to the philosophical and literary production of P. A. Florenskii has become commonplace. The thinker's intellectual legacy is very great. In September 1919, Florenskii wrote a prospectus for a collection of his own writings, which would have amounted to nineteen volumes. The collection was not published, for a number of reasons; nonetheless, many of the philosopher's works did come out during his lifetime. Florenskii's writing, published in small editions and scattered among various journals, are still quite (...) inaccessible to readers. (shrink)

The hardest thing in appropriating [a] holistic natural law perspective is to recognise the invisible mean of judgement, which alone contains the limits of all things... The notion of mean and limits - so fundamental to ethics - calls for inner understanding that the nature of the mean cannot be defined 'a priori', because it involves an exercise of judgement, ethical judgement.

McGavin, PA The Holy Father often speaks without a prepared text, and it is amazing how accurately he reads in transcription. This was brilliantly so in Light of the World interviews. Even his brief words at pages 118-119 on condoms - so breathlessly and inaccurately treated in the media - are so cast as to withstand close scrutiny. It is with this recognition that I address his lack of precision and perception in speaking on the question of homosexuality and sacred (...) ordination. (shrink)

Audio recording of "a group of Philosophical and Environmental Songs," as described by Gunter.

The overall objectives of this article are to help the reader see and understand through Aristotelian lenses: (1) positive and negative aspects of the Leveraged Buyout (LBO) business model; and, (2) how LBO practices can be reformed so as to retain positives and reduce negatives. Aristotelian lenses considered are: wealth acquisition through wealth expansion, wealth creation, and wealth transfers; distributive and corrective justice; and, a dialectic analytic process of retaining positives, reducing negatives, and reforming. Key net positive wealth expansion aspects (...) of the model are discussed with respect to: profitability for the owners, managers, and investors of LBO firms; potential productivity improvements on the cost and revenue sides; and, potentially greater credit availability. Negative wealth transfer and destruction aspects with respect to: a relatively high rate of bankruptcies in some countries and in economic downturns; LBO firm gains without responsibility for losses; wealth transfers from employees, creditors, ordinary vs “carried interest” taxpayers; and, damaged wealth expansion and creation capabilities of acquired organizations are discussed. Potential reforms that could reduce negatives, retain positives, and reform the model are discussed. (shrink)
