How theories of practice can inform transition to a decarbonised transport system
In this article, I explore the potential of theories of practice to inform the socio-technical transition required to adequately decarbonise the UK transport system. To do so I push existing applications of practice theories by articulating a āsystems of practiceā approach, which articulates theories of practice with socio-technical systems approaches. After sketching out a theory of practice, I explore the potential of a practice theory approach to illuminate systemic change in transport. I do this by confronting two key criticisms of practice theories; first of their difficulty in accounting for change; second in their limited ability to move beyond a micro-level focus on doing. The counter I offer to these criticisms leads directly into recognising how theories of practice can articulate with socio-technical systems approaches. From this basis, I go on to consider the implications of a practice theory approach for informing interventions to effect a system transition towards decarbonised transport
Experimental aspects of colour reconnection
This report summarises experimental aspects of the phenomena of colour
reconnection in W+W- production, concentrating on charged multiplicity and
event shapes, which were carried out as part of the Phenomenology Workshop on
LEP2 Physics, Oxford, Physics Department and Keble College, 14-18 April, 1997.
The work includes new estimates of the systematic uncertainty which may be
attributed to colour reconnection effects in experimental measurements of Mw.Comment: 10 pages, 4 figures. To be published in proceedings of Phenomenology

First Amendment Challenges to Landmark Preservation Statutes
The Interfaith Commission, religious leaders deeply concerned with the problems associated with the landmarking of religious properties, have recognized that the prohibition against demolition or alteration of landmarked religious properties effectively destroys their value. Additionally, the religious organizations are required to expend thousands of dollars of religious contributions to maintain these landmarks for the public benefit, in accordance with the regulations of the Landmarks Commission. This Comment focuses on the constitutionality of landmark preservation statutes as applied to religious properties. Using New York City as a model, this Comment examines the myriad problems presented by the landmarking of religious properties. This Comment concludes that a re-examination of the New York standard under the constitutional test requires the resolution of whether the preservation of landmarks is a compelling state interest sufficient to justify the burden of maintaining landmarks which has been placed on religious organizations
Theories of practice and geography
Recent developments in theories of practice have seen place and space taken explicitly into account. In particular,
THEODORE SCHATZKIās āsite ontologyā offers distinctive but as yet under-explored means of engaging with human
geographies. By giving ontological priority to practices as constitutive of the social, this kind of practice theory provides an integrative conceptual framework that enables the analysis of diverse phenomena in relation to each other, over space and time, as they are constituted through practices. This article develops an outline agenda for bringing theories of practice, and particularly SCHATZKIās āsite ontologyā, together with geographical inquiry. We elucidate this agenda through consideration of three contemporary preoccupations in human geography, comprising emotion, materiality and knowledge
The stewardship of things: Property and responsibility in the management of manufactured goods
In the context of broad-based concerns about the need to move towards a more sustainable materials economy, particularly as they are expressed in debates around ecological modernisation (EM), we argue that product stewardship has radical potential as a means to promote significant change in the relationship between society and the material world. We focus on two important dimensions that have been neglected in approaches to product stewardship to date. Firstly, we argue that immanent within the basic concept of stewardship is a problematisation of dominant understandings of property ownership in neoliberal market economies. In the space opened up by notions of stewardship, different ways of enacting both rights and responsibilities to products and materials emerge which have potential to advance the sustainability of material economies. Secondly, through exploration of existing expressions of product stewardship, we uncover a neglected scale of action. Both policy and dominant articulations of EM focus primarily on the efficiency of production processes; and secondarily, the attitudes and behaviours of individual consumers. Missing from this is the 'meso-scale' of social collectives including households, neighbourhoods, more distributed communities and small scale social enterprises. Based on a review of existing research from Australia and the UK, including our own, we argue that understanding of embedded practices of material responsibility at the household scale can both reinvigorate the concept of product stewardship as a potentially radical intervention, and reveal the potential of the meso-scale as a challenging but worthwhile realm of policy intervention

Gluon Correlators in the Kogan-Kovner Model
The Lorentz-invariant gluon correlation functions, corresponding to scalar
and pseudo-scalar glueballs, are calculated for Kogan's and Kovner's
variational ansatz for the pure SU(N) Yang-Mills wavefunctional.
One expects that only one dynamical mass scale should be present in QCD; the
ansatz generates the expected scale for both glueballs, as well as an
additional scale for the scalar glueball. The additional mass scale must
therefore vanish, or be close to the expected one. This is shown to constrain
the nature of the phase transition in the Kogan-Kovner ansatz.Comment: 9 pages, no figure

Lateral fricatives and lateral emphatics in southern Saudi Arabia and Mehri
Arabic was traditionally described as lughat al-Ī”Äd āthe language of Ī”Ädā due to the perceived unusualness of the sound. From SÄ«bawayhiās description, early Arabic Ī”Äd was clearly a lateral or lateralized emphatic. Lateral fricatives are assumed to have formed part of the phoneme inventory of Proto-Semitic, and are attested in Modern South Arabian languages (MSAL) today. In Arabic, a lateral realization of Ī”Äd continues to be attested in some recitations of the QurĪÄn. For Arabic, the lateral Ī”Äd described by SÄ«bawayhi was believed to be confined to dialects spoken in ŠaĪ”ramawt. Recent fieldwork by Asiri and al-Azraqi, however, has identified lateral and lateralized emphatics in dialects of southern ĪAsÄ«r and the Saudi TihÄmah. These sounds differ across the varieties, both in their phonation (voicing) and manner of articulation ā sonorants and voiced and voiceless fricatives ā in their
degree of laterality, and in their phonological behaviour: the lateralized Ī”Äd in the southern Yemeni dialect of GhaylĪabbÄn, for example, has a non-lateralized allophone in the environment of /r/ or /l/. Recent phonetic work conducted by Watson on the Modern South Arabian language, Mehri, shows a similar range of cross-dialect variety in the realization of the lateral(ized) emphatic. In
this paper, we discuss different reflexes of lateral(ized) emphatics in four dialects of the Saudi TihÄmah; we show that some of these dialects contrast cognates of *Ī” and *Ī; and we show that lateral emphatics attested in dialects of the Modern South Arabian language, Mehri, spoken in areas considerably to the south of the Saudi TihÄmah, show a similar degree of variation to that of the Arabic dialects of the Saudi TihÄmah
