Categorical models for equivariant classifying spaces

Starting categorically, we give simple and precise models of equivariant classifying spaces. We need these models for work in progress in equivariant infinite loop space theory and equivariant algebraic K-theory, but the models are of independent interest in equivariant bundle theory and especially equivariant covering space theory.Comment: 29 pages. Revised version, to appear in AGT. Considerable changes of notation and organization and other changes aimed at making the paper more user friendl

Diagram spaces, diagram spectra, and spectra of units

This article compares the infinite loop spaces associated to symmetric spectra, orthogonal spectra, and EKMM S-modules. Each of these categories of structured spectra has a corresponding category of structured spaces that receives the infinite loop space functor \Omega^\infty. We prove that these models for spaces are Quillen equivalent and that the infinite loop space functors \Omega^\infty agree. This comparison is then used to show that two different constructions of the spectrum of units gl_1 R of a commutative ring spectrum R agree.Comment: 62 pages. The definition of the functor \mathbb{Q} is changed. Sections 8, 9, 17 and 18 contain revisions and/or new materia

Repugnance as Performance Error: The Role of Disgust in Bioethical Intuitions

An influential argument in bioethics involves appeal to disgust, calling on us to take it seriously as a moral guide (e.g. Kass, Miller, Kahan). Some argue, for example, that genetic enhancement, especially via human reproductive cloning, is repellant or grotesque. While objectors have argued that repugnance is morally irrelevant (e.g. Nussbaum, Kelly), I argue that the problem is more fundamental: it is psychologically irrelevant. Examining recent empirical data suggests that disgust’s influence on moral judgment may be like fatigue: an exogenous influence, yielding a “performance error” that does not reflect our understanding of moral matters. This conclusion also challenges appeals to repugnance on other topics (such as homosexuality) and generally downplays the importance of disgust in moral discourse

House of Commons Select Committee on Transport: Inquiry into Urban Congestion Charging

INTRODUCTION This evidence, submitted to the Select Committee for its inquiry into Urban Congestion Charging, is based on my research into the subject, and professional involvement in studies of methods for managing the demand for urban travel, over the last twenty years. In the 1970s I was responsible, within the Greater London Council, for their studies of the use of comprehensive parking control, physical restriction of road space, and supplementary licensing (a low technology method of congestion charging) as methods of traffic restraint. At the same time, I was an adviser to the World Bank in its study of Singapore's area licensing scheme which is still the only congestion charging system in operation. In the 1980s I was an adviser to the US Transport Research Board in its investigation of appropriate methods for managing urban traffic, and to The MVA Consultancy in its study of electronic road pricing for Hong Kong. Since 1987 I have been involved, as a director of The MVA Consultancy, in a series of integrated transport studies in London (for the London Planning Advisory Committee), Birmingham, Edinburgh, Bristol and Merseyside, each of which has investigated the role of congestion charging as part of a wider transport strategy. I am currently directing a programme of research, funded by the Engineering and Physical Sciences Research Council, which is assessing the relative impact on urban road networks of different methods of imposing congestion charging, on their own and in combination with traffic signal control and bus priorities. This research has used Cambridge and York as case studies. In addition, I am currently acting as one of the technical advisers to the Department of Transport's study of congestion charging in London.

Rearticulating the case for minority language rights

While advocacy of minority language rights (MLR) has become well established in sociolinguistics, language policy and planning and the wider human rights literature, it has also come under increased criticism in recent times for a number of key limitations. In this paper, I address directly three current key criticisms of the MLR movement. The first is a perceived tendency towards essentialism in articulations of language rights. The second is the apparent utopianism and artificiality of 'reversing language shift' in the face of wider social and political 'realities'. And the third is that the individual mobility of minority-language speakers is far better served by shifting to a majority language. While acknowledging the perspicacity of some of these arguments, I aim to rearticulate a defence of minority language rights that effectively addresses these key concerns. This requires, however, a sociohistorical/sociopolitical rather than a biological/ecological analysis of MLR. In addition, I will argue that a sociohistorical/sociopolitical defence of MLR can problematise the positions often adopted by minority language rights' critics themselves, particularly those who defend majoritarian forms of linguistic essentialism and those who sever the instrumental/identity aspects of language. Implications for language policy and planning will also be discussed

Lyrics in Congregational Song: A Biblical and Historical Survey

Is there a standard as to what constitutes biblical, God-honoring congregational song lyrics? In this paper, I will seek to address this question through a review of relevant biblical principles and positions of prominent leaders throughout church history. The Bible provides a language of worship in the Psalms and includes some information regarding singing in the New Testament. Biblical principles have been applied throughout the centuries by various church fathers. The synthesis of biblical principles and historical contributions will produce a set of guidelines by which congregational song lyrics may be evaluated for the purpose of contextual application in modern services
