+Numerous variations and extensions of effect handlers have been
+proposed since their inceptions.  In this dissertation I restrict my
+attention to \citeauthor{PlotkinP09}'s deep handlers, their shallow
+variation, and parameterised handlers which are a slight variation of
+deep handlers. In particular I work with free algebraic theories,
+which is to say my designs do not incorporate equational theories for
+effects. Furthermore, I frame my study in terms of simply-typed and
+polymorphic $\lambda$-calculi for which I give computational
+interpretations in terms of contextual operational semantics and
+realise using two foundational operational techniques: continuation
+passing style and abstract machine semantics. When it comes to
+expressivity studies there are multiple complementary notions of
+expressiveness available in the literature; in this dissertation I
+work with typed macro-expressiveness and type-respecting
+expressiveness notions.

+\subsection{Scope extrusion}
 The literature on effect handlers is rich, and my dissertation is but
 one of many on topics related to effect handlers. In this section I
 provide a few pointers to related work involving effect handlers that
 I will not otherwise discuss in this dissertation.
