Relationism Rehabilitated? I: Classical Mechanics
No full textThe implications for the substantivalist--relationist controversy of Barbour and Bertotti's successful implementation of a Machian approach to dynamics are investigated. It is argued that in the context of Newtonian mechanics the Machian framework provides a genuinely relational interpretation of dynamics and that it is more explanatory than the conventional, substantival interpretation. In a companion paper (Pooley 2001), the implications of the Machian approach for the interpretation of relativistic physics are explored

Changing home and workplace in Victorian London : the life of Henry Jaques shirtmaker.
No full textThe paper uses unusually rich evidence from a manuscript life history written in 1901 from personal diaries to explore the changing relationship between home and workplace in Victorian London. The life history of Henry Jaques demonstrates the way in which decisions about employment and residence were related both to each other and to stages of the family life course. The uncertainty of work, lack of income to support a growing family, rising aspirations, the constant threat of illness, the ease of moving between rented property, close ties between home and workplace, the stresses produced by home working, and the attractions of suburbanization all interacted to shape the residential and employment history of Jaques and his family. The themes exemplified by this detailed life history were also relevant to many other people. Evidence collected from a large-scale project on lifetime residential histories is used to place the experiences of Henry Jaques in a broader context, and to show how they related to the changing social and economic structure of Victorian London

Chandra Observations of A 1.9 Kpc Separation Double X-Ray Source in A Candidate Dual Active Galactic Nucleus Galaxy At Z=0.16
No full textWe report Chandra observations of a double X-ray source in the z = 0.1569 galaxy SDSS J171544.05+600835.7. The galaxy was initially identified as a dual active galactic nucleus (AGN) candidate based on the double-peaked [O III] lambda 5007 emission lines, with a line-of-sight velocity separation of 350 km s(-1), in its Sloan Digital Sky Survey spectrum. We used the Kast Spectrograph at Lick Observatory to obtain two long-slit spectra of the galaxy at two different position angles, which reveal that the two Type 2 AGN emission components have not only a velocity offset, but also a projected spatial offset of 1.9 h(70)(-1) kpc on the sky. Chandra/ACIS observations of two X-ray sources with the same spatial offset and orientation as the optical emission suggest that the galaxy most likely contains Compton-thick dual AGNs, although the observations could also be explained by AGN jets. Deeper X-ray observations that reveal Fe K lines, if present, would distinguish between the two scenarios. The observations of a double X-ray source in SDSS J171544.05+600835.7 are a proof of concept for a new, systematic detection method that selects promising dual AGN candidates from ground-based spectroscopy that exhibits both velocity and spatial offsets in the AGN emission features.W.J.

No full textConstructing a suburban identity : youth, femininity and modernity in late-Victorian Merseyside.
No full textSuburban growth was one of the main characteristics of late-nineteenth-century British towns, and a suburban life style rapidly became the aspiration of a high proportion of urban dwellers. This paper explores the experience of one young woman growing up in a late-Victorian suburb, and assesses the ways in which she negotiated the structures of this emerging ‘modern’ environment, so as to construct her own identity and behaviour. Evidence is drawn from one very detailed diary covering the period 1884 to 1892, and attention is focused on three aspects of everyday life: public and social space; domestic routine; and friendships and relationships. The conventional view of middle-class suburban domesticity is challenged by evidence from this diary, which suggests that it was the public and social life of the suburb that was of particular importance to young women. While older married women’s experiences were centred upon maintaining a respectable home, the provincial suburban environment offered to young single women considerable opportunities for independent mobility and action, which were restricted by relatively few familial constraints. The diarist did not fundamentally challenge the culture of middle-class suburbia, but instead was able to manipulate many social expectations to her own advantage. As a site of on-going development and malleable norms, late-nineteenth-century suburbia offered its young elite residents opportunities for a certain degree of social, cultural and spatial autonomy that was understood to be essential to the life of the nascent community

Comments on Sklar's ``Barbour's Relationist Metric of Time''
No full textJulian Barbour's approach to dynamics is reviewed. With a particular focus on questions of explanation and confirmation, the approach is contrasted with standard formulations of dynamics. This paper expands upon my commentary on Lawrence Sklar's paper at the Philosophy of Time Society meeting at the APA's Central Division meeting in Chicago, April 2004. Although a commentary, the current paper is comprehensible without reference to Sklar's paper
