Despite fiscal stress, public confidence in the National Health Service (NHS) remains strong; privatisation has not hollowed out the service. But if long term challenges are to be overcome, pragmatism not rhetoric should be the guide.

Though political scientists generally understand the origins of native-born reactions to foreigners, less is known about how anti-immigrant contexts trigger a political response within immigrant groups. I address this question by studying the connection between xenophobic rhetoric and Latino politics. I claim that xenophobic rhetoric raises the salience of ethnic identity and impugns its worth....

Children’s language acquisition is normally explained either in biological, nativist or in functionalist and usage based terms. The main thesis of this article is that rhetorical terminology introduced by Aristotle is fruitful for our understanding of the development process children go through when learning language. Introducing rhetoric to descriptions of children’s language acquisition presu...

We introduce and study the notions of a PAC substructure of a stable structure, and a bounded substructure of an arbitrary substructure, generalizing [8]. We give precise definitions and equivalences, saying what it means for properties such as PAC to be first order, study some examples (such as differentially closed fields) in detail, relate the material to generic automorphisms, and generaliz...

To what extent is learnability impeded when information is missing in learning instances? We present relevant known results and concrete open problems, in the context of a natural extension of the PAC learning model that accounts for arbitrarily missing information.

Previous results on nonlearnability of visual concepts relied on the assumption that such concepts are represented as sets of pixels [l]. This correspondence uses an approach developed by Haussler [2] to show that under an alternative, feature-based representation, recognition is PAC learnable from a feasible number of examples in a distribution-free manner.
