  • Let X be a compact metric space and let $f: X\!\rightarrow \! X$ be a homeomorphism on X. We show that if f is both pointwise recurrent and expansive, then the dynamical system $(X, f)$ is topologically conjugate to a subshift of some symbolic system. Moreover, if f is pointwise positively recurrent, then the subshift is semisimple; a counterexample is given to show the necessity of positive recurrence to ensure the semisimplicity.

Language as Symbolic Power

  • Language is not simply a tool for communication - symbolic power struggles underlie any speech act, discourse move, or verbal interaction, be it in face-to-face conversations, online tweets or political debates. This book provides a clear and accessible introduction to the topic of language and power from an applied linguistics perspective. It is clearly split into three sections: the power of symbolic representation, the power of symbolic action and the power to create symbolic reality. It draws upon a wide range of existing work by philosophers, sociolinguists, sociologists and applied linguists, and includes current real-world examples, to provide a fresh insight into a topic that is of particular significance and interest in the current political climate and in our increasingly digital age. The book shows the workings of language as symbolic power in educational, social, cultural and political settings and discusses ways to respond to and even resist symbolic violence.
