Abstract For a quasi-regular (symmetric) Dirichlet space (E ,F) and an associated symmetric standard process (Xt, Px), we show that, for u ∈ F , the additive functional u∗(Xt) − u∗(X0) is a semimartingale if and only if there exists an E-nest {Fn} and positive constants Cn such that |E(u, v)| ≤ Cn‖v‖∞, v ∈ FFn,b. In particular, a signed measure resulting from the inequality will be automaticall...

We study a class of Piecewise Deterministic Markov Processes with state space R d × E where E is a finite set. The continuous component evolves according to a smooth vector field that is switched at the jump times of the discrete coordinate. The jump rates may depend on the whole position of the process. Working under the general assumption that the process stays in a compact set, we detail a p...

The aim of this paper is to introduce and explain a number of important existentialist philosophers and concepts that we believe can contribute to a critical approach to leadership theory. Emphasis is placed on understanding the nature of communication from an existentialist perspective and so Jaspers’ conceptualisation of existential communication is introduced along with important related con...

Synposis: The goal of this book is to show that key ideas about the nature of selves and responsibility for character in the existential tradition can be reconstructed and defended with the kind of hierarchical theory of personal autonomy proposed by Harry Frankfurt, Gerald Dworkin, and since developed by many others. But to solve the regress problem with hierarchical analyses of autonomy, whil...
