This article provides an overview of current and prospective ethical issues facing commercial (as opposed to leisure) travel agents. Industry wide ethical issues include conflicting pressures from suppliers and clients, competency requirements for agents and misleading advertising and sales claims (vaporware in industry jargon). Issues with travel suppliers include calculation and payment of commissions, fare loopholes, frequent flyer plans and the use and abuse of benefits directed to individual employees. Issues with corporate clients of travel agents include hidden preferred carriers (...) or suppliers, client pressure to use fare loopholes and hidden relationships with corporate travel consultants. Future issues include protecting client privacy, free riding, and divergent international business practices. (shrink)
While psychoanalysis credits the entrenchment of systems of subordination to the necessity of socialization and the transmission of dominant values from parent to child, by claiming social symbolics independent of the dominant hegemony, W.E.B. Du Bois calls for resistant forms of identification. Psychoanalyticaccounts of social power relations often assume that the dominant social group produces the only operative social symbolic and that this symbolic is also identical with the nation, but Du Bois’s attention to the slave song allows him to (...) trace the burial of a black American symbolic rather than a traumatic inculcation of the dominant white symbolic.

Historically, for Black writers, literary fiction has been a site for transforming the discursive disciplinary spaces of political oppression. From 19th century “slave narratives” to the 20th century, Black novelists have created an impressive literary counter-canon in advancing liberatory struggles. W.E.B. Du Bois argued that “all art is political.” Many Black writers have used fiction to create spaces for political and social freedom—from the early work of Harriet Wilson’s Our Nig; or, Sketches from the Life of a (...) Free Black (1859)—to the enduring works of the Harlem Renaissance (Toomer, Hurston, and Schuyler)—to the great revolutionary Black literature after WWII (Wright, Baldwin, Williams)—to contemporary Black writers (Toni Morrison, Edward Jones, Samuel Delany)—Black fictive space continues to be a necessary site for resistance. Black literary fiction is a vast counter-canon to mainstream literature which unquestioningly reinforces global white supremacy, capitalistic political oppressions, and the dominance/subordinance relations upon which they depend.

The generalized second law of thermodynamics states that entropy always increases when all event horizons are attributed with an entropy proportional to their area. We test the generalized second law by investigating the change in entropy when dust, radiation and black holes cross a cosmological event horizon. We generalize for flat, open and closed Friedmann–Robertson–Walker universes by using numerical calculations to determine the cosmological horizon evolution. In most cases, the loss of entropy from within the cosmological horizon is more (...) than balanced by an increase in cosmological event horizon entropy, maintaining the validity of the generalized second law of thermodynamics. However, an intriguing set of open universe models shows an apparent entropy decrease when black holes disappear over the cosmological event horizon. We anticipate that this apparent violation of the generalized second law will disappear when solutions are available for black holes embedded in arbitrary backgrounds. (shrink)
This article reports on a study of interaction between Americans who self-identify as Black and White that reveals underlying expectations with regard to conversation that differ between the two groups. These differences seem not to have much to do with class or gender, but rather vary largely according to self-identification by "race." The argument of this paper will be that the social phenomena of "race" are constructed at the level of interaction whenever Americans self-identified as Black and White (...) speak to one another. This is because the Interaction Order expectations with regard to both self and community vary between the two groups. Because the "language games" and conversational "preferences" practiced by the two groups are responsive to different Interaction Orders, the "working consensus" is substantially different, and as a consequence, conversational "moves" are not recognizably the same. It will be argued that a great deal of institutional discrimination against African Americans can be traced to this source. (shrink)
W. B. Gallie's words about Peirce's cosmology—"the black sheep or white elephant of his philosophical progeny" (1952, p. 216)—have often been quoted, usually as a preface to giving a better account of the animal. That he attributed the view to 'contemporary philosophers' and did not assert it himself has usually been ignored. True, Gallie did argue that the "cosmology is a failure, and an inevitable failure" (p. 236), but he also said that Peirce himself "recognized … that his work (...) in this field was imperfect and sketchy" (p. 215), and he concluded the chapter, and his book, with an extremely sympathetic account of all that is nevertheless of enduring value in that failure. After studying Peirce's writings of his .. (shrink)
The photographer and reformer Jacob Riis once wrote, “I have seen an armful of daisies keep the peace of a block better than a policeman and his club.” Riis was not alone in his belief that beauty could tame urban chaos, but are aesthetic experiences always a social good? Could aesthetics also inspire violent crime, working-class unrest, and racial murder? To answer these questions, Russ Castronovo turns to those who debated claims that art could democratize culture—civic reformers, anarchists, novelists, civil (...) rights activists, and college professors—to reveal that beauty provides unexpected occasions for radical, even revolutionary, political thinking. B eautiful Democracy explores the intersection of beauty and violence by examining university lectures and course materials on aesthetics from a century ago along with riots, acts of domestic terrorism, magic lantern exhibitions, and other public spectacles. Philosophical aesthetics, realist novels, urban photography, and black periodicals, Castronovo argues, inspired and instigated all sorts of collective social endeavors, from the progressive nature of tenement reform to the horrors of lynching. Discussing Jane Addams, W.E.B. Du Bois, Charlie Chaplin, William Dean Howells, and Riis as aesthetic theorists in the company of Kant and Schiller, Beautiful Democracy ultimately suggests that the distance separating academic thinking and popular wisdom about social transformation is narrower than we generally suppose.

Adrono's jazz essays have attracted considerable notoriety not only for their negative and dismissive evaluation of jazz as music but for their outright dismissal of all the claims made on behalf of jazz by its exponents and admirers, even of claims concerning the black origins of jazz music. This paper offers a critical exposition of Adorno's views on jazz and outlines an alternative theory of the culture industry as the basis of a critique of Adorno's critical theory. Adorno's arguments (...) are discussed in the context of his wider theoretical commitment to a model of structuration-in both musical and social relations-that establishes a dividing line between a moral aesthetic praxis that can be approved as having "truth-value" and one that betrays and subverts the truth. In Adorno's analysis, jazz finds itself positioned on the wrong side of that line and, accordingly, is condemned. It is argued that it is Adorno's commitment to a formalist model of art works that has been superseded by modern aesthetic practice in both so-called "serious" art as well as in the works of the culture industries that binds him to a regressive model of aesthetic praxis. An alternative theory of the culture industry is outlined that explores its positive functions in enhancing the resources available for culture creation through its transmission of aesthetic codes, and in mediating relations between so-called high and low art.

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not (...) be of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language–conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed. (shrink)
I suppose that 'ravens are black' is an inexact generalization having a degree of truth measured by the proportion of ravens that are black, and a probability measured by its expected degree of truth in different 'possible worlds.' Given this, 'ravens are black' differs in truth, probability, and confirmation from 'non-black things are not ravens', and this suggests a new approach to Hempel's Paradox as well as to other aspects of confirmation. Basic concepts of a formal (...) theory developing this approach are described, and some of its fundamental laws are given, together with sketches of applications. (shrink)
How do people use past experience to generalise to novel cases? This paper reports four experiments exploring the significance on one class of past experiences: encounters with negative or contrasting cases. In trying to decide whether all ravens are black, what is the effect of learning about a non-raven that is not black? Two experiments with preschool-aged, young school-aged, and adult participants revealed that providing a negative example in addition to a positive example supports generalisation. Two additional experiments (...) went on to ask which kinds of negative examples offer the most support for generalisations. These studies contrasted similarity-based and category-based accounts of inductive generalisation. Results supported category-based predictions, but only for preschool-aged children. Overall, the younger children showed a greater reliance on negative evidence than did older children and adults. Most things we encounter in the world are negative evidence for our generalisations. Understanding the role of negative evidence is central for psychological theories of inductive generalisation. (shrink)
The oft-neglected issue of the causal structure in the flat spacetime approach to Einstein's theory of gravity is considered. Consistency requires that the flat metric's null cone be respected, but this does not automatically happen. After reviewing the history of this problem, we introduce a generalized eigenvector formalism to give a kinematic description of the relation between the two null cones, based on the Segre' classification of symmetric rank 2 tensors with respect to a Lorentzian metric. Then we propose a (...) method to enforce special relativistic causality by using the gauge freedom to restrict the configuration space suitably. A set of new variables just covers this smaller configuration space and respects the flat metric's null cone automatically. Respecting the flat metric's null cone ensures that the spacetime is globally hyperbolic, indicating that the Hawking black hole information loss paradox does not arise in the special relativistic approach to Einstein's theory.

An analogue of Hawking's black hole area theorem is proved for Friedmann-type cosmological models with event horizons. The generalised second law of thermodynamics is investigated in cases where the horizon shrinks.
The Unruh-Wald scenario for mining quantum black holes is applied to de Sitter space. The following questions are addressed: Will the generalized second law of thermodynamics be maintained for de Sitter horizons? Does the mining process allow the recovery of unlimited energy from the cosmological gravitational field? The evaporation of a black hole in de Sitter space is also investigated in the context of the second law.
We discuss the Starobinskii-Unruh process for the Kerr black hole. We show how this effect is related to the theory of squeezed states. We then consider a simple model for a highly relativistic rotating star and show that the Starobinskii-Unruh effect is absent.
This paper is a philosophical, socio-political, analysis of the problem of democratic despair and the possibility of finding hope in the midst of it. The analysis spring boards from a dialectical discussion on the state of Black America between Harry Belafonte, Minister Louis Farrakhan, and Cornel West, to an examination of the reasons for believing this house called America is on fire. The paper then moves to two possible responses for African Americans to the burning house: separatism (physical or (...) psychological), and radical cultural pluralism grounded in a transformative deep democracy. The paper opts for the latter, concludes by offering a new cultural pluralistic democracy as a model for hope, and suggests the basic tools necessary for building such a transformative democracy.

The massless Thirring model of a self-interacting ferinion field in a curved two-dimensional background spacetime is considered. The exact operator solution for the fields and the equation for the two-point function are given and used to examine the radiation emitted by a two-dimensional black hole. The radiation is found to be thermal in nature, confirming general predictions to this effect. We compute the particle spectrum of the Thirring fermions at finite temperature in Minkowski space and point out errors in (...) a previous attempt at this calculation. Finally we calculate the vacuum expectation value of the stress tensor in an arbitrary two-dimensional spacetime by exploiting the connection between the thermal Hawking radiation from a black hole and the value of the so-called conformal trace anomaly. The latter is also computed quite independently, using dimensional regularization, from general considerations of the renormalization group. (shrink)
In this sweeping survey, acclaimed science writers Paul Davies and John Gribbin provide a complete overview of advances in the study of physics that have revolutionized modern science. From the weird world of quarks and the theory of relativity to the latest ideas about the birth of the cosmos, the authors find evidence for a massive paradigm shift. Developments in the studies of black holes, cosmic strings, solitons, and chaos theory challenge commonsense concepts of space, time, and matter, and (...) demand a radically altered and more fully unified view of the universe.

A hierarchical ordering of approaches afflicts environmental thinking. An ethics of individualism unjustly overrides social/political philosophy in environmental debates. Dialectics helps correct this imbalance. In dialectical fashion, a synthesis emerges between conflicting approaches to dialectics and to nature from: Marxism (Levins and Lewontin), anarchism (Bookchin), and Native Americanism (Black Elk). Conflicting (according to Marxists) and cooperative (according to anarchists) forces both operate in nature. Ethics (anarchist), political theory (Marxist), and spirituality (Native American) constitute the interconnected interpretative domains of a (...) dialectically informed ecophilosophy. In a world painted too often in blacks and whites, ecological dialectics colors the picture a more realistic gray. (shrink)
The authors relate the major groups involved in the desegregation of Boston's public schools to divergent understandings of rights in America's political and religious traditions. After an initial historical review, the authors suggest that the desegregation controversy may be understood as a conflict between a natural law theory of rights which requires remedial action to correct injustices and a traditionalist theory which sanctions prevailing liberties. In Boston, one natural law position is represented by black parents and the Federal court's (...) desegregation orders. Another position is represented by many white parents, who base their opposition to desegregation on a traditionalist notion of natural law. The authors suggest that any permanent resolution of the conflict must address these divergent understandings of natural law, as well as the political realities peculiar to Boston. (shrink)
Oxford Studies in Metaphysics is the forum for the best new work in this flourishing field. Much of the most interesting work in philosophy today is metaphysical in character: this new series is a much-needed focus for it. OSM offers a broad view of the subject, featuring not only the traditionally central topics such as existence, identity, modality, time, and causation, but also the rich clusters of metaphysical questions in neighbouring fields, such as philosophy of mind and philosophy of science. (...) Besides independent essays, volumes will often contain a critical essay on a recent book, or a symposium that allows participants to respond to one another's criticisms and questions. Anyone who wants to know what's happening in metaphysics can start here. -/- Volume Two begins with a major paper on consciousness by Ned Block. Block examines 'Max Black's Objection to Mind-Body Identity', an argument for a dualism of physical and phenomenal properties, closely related to Jackson's 'knowledge argument'. His extensive exploration of this family of arguments for property dualism includes considerable discussion of John Perry and Stephen White; their responses to Block's paper complete the section on the metaphysics of consciousness. -/- Three papers consider the thesis that the future is, in some sense, 'open'. Eli Hirsch elaborates a view according to which contingent statements about the future can be indeterminate in truth-value, while preserving 'straight logic', including a principle of bivalence. Peter Forrest defends a sort of 'growing block' theory of the passage of time, emphasizing the way such a metaphysics, combined with a truth-maker principle, can provide an analysis of natural necessity. Trenton Merricks presents a trenchant and original criticism of the 'growing block' theory of time. -/- The volume continues with a group of papers on problems of ontology. Thomas Hofweber's paper, defending nominalism from the objection that there are 'inexpressible' properties and propositions, won the first annual Oxford Studies in Metaphysics Younger Scholar Prize. The papers by Phillip Bricker and Michael Loux examine a couple of deep divides within ontology. John Hawthorne's paper raises some extremely puzzling questions about the nature of persons, given the ontology needed for Timothy Williamson's theory of vagueness. Hawthorne uses these problems to motivate an alternative style of epistemicism. -/- The final three papers take up several issues in the metaphysics of traditional theism. Michael Bergmann and Jeffrey Brower raise objections to combining a Platonic conception of universals with the doctrine of divine aseity; while Brian Leftow defends a non-Platonic theory of universals - a kind of divine-concept nominalism. Hud Hudson suggests that contemplation of the possibility of higher dimensions opens up new avenues in theodicy. (shrink)
