Abstract This study examines the situated use of rules and social practices people deploy to correct projectable rule violations in pétanque playing activities. Drawing on Ethnomethodology Conversation Analysis, using naturally occurring video recordings, this article investigates socially organized occasions use, more particularly how for turn-taking at play are reflexively established through...

We construct, for a second-order homogeneous Lagrangian in two independent variables, a differential 2-form with the property that it is closed precisely when the Lagrangian is null. This is similar to the property of the ‘fundamental Lepage equivalent’ associated with first-order Lagrangians defined on jets of sections of a fibred manifold. We show that this form may be defined on a fourth-ord...

Recent versions of the Extended Standard Theory (e.g., Chomsky 1981, 1986) have proposed that syntactic structures are largely projectable from the properties of their constituent lexical items in particular, from their thematic properties. In this paper I argue for an extension of this approach to nominal structure. My focus will not be on nominals related in an obvious way to verbal projectio...

The simplest proofs of the Church Rosser Property are usually done by the syntactic method of parallel reduction. On the other hand, reducibility is a semantic method which has been used to prove a number of properties in the λ-calculus and is well known to offer on one hand very general proofs which can be applied to a number of instantiations, and on the other hand, to be quite mysterious and...

In this article the frame-theoretic account of what is archimedean for order-algebraists, and semisimple for people who study commutative rings, deepens with the introduction of J -frames: compact normal frames that are join-generated by their saturated elements. Yosida frames are examples of these. In the category of J -frames with suitable skeletal morphisms, the strongly projectable frames a...

We quantize the two-dimensional projectable Hor?va-Lifshitz gravity with a bi-local as well space-like wormhole interaction. The resulting quantum Hamiltonian coincides one obtained through summing over all genus in string field theory for causal dynamical triangulations. This implies that our interaction can be interpreted splitting or joining of one-dimensional strings.
