An extension of an abstract argumentation framework is introduced that provides a direct representation of global conflicts between sets of arguments. The extension, called collective argumentation, turns out to be suitable for representing semantics of disjunctive logic programs. Collective argumentation theories are shown to possess a four-valued semantics, and are closely related to multiple...

The aim of this paper is to examine critically Lucas’ arguments against Keynes’s General Theory and in particular against Keynes’s concept of involuntary unemployment. It comprises two main parts. In the first, I question Lucas’s claim that Keynes betrayed the equilibrium discipline by freeing himself from the postulates of optimising behaviour and market clearing. In the second, I discuss Luca...

Arguments are given that time must be defined in an operative manner,i.e., by constructing devices which can serve as clocks.The investigation of such devices leads to the conclusion that there is a principal uncertainity of time if one considers periods which are not large compared with the Planck time. Thus,according to the old (classical) concept,time cannot be well-defined at this scale.The...

Application-Layer Protocol Negotiation (ALPN) labels for Session Traversal Utilities for NAT (STUN) usages, such as Traversal Using Relays around NAT (TURN) and NAT discovery, are defined in this document to allow an application layer to negotiate STUN usages within the Transport Layer Security (TLS) connection. ALPN protocol identifiers defined in this document apply to both TLS and Datagram T...

In this paper I will explore some of the arguments surrounding the concept of the psychosomatic and psychosomatic disorders. As will become clear this is an idea which has a difficult history within psychoanalysis, and even today there appears to be no clear agreement as to whether the concept of the psychosomatic has any place at all within analytic discourse. I will begin the discussion by ou...

The possibility of observing negative Shapiro-like gravitational time delay (or advancement) due to the Earth’s gravity employing interferometric experiments on surface is discussed. It suggested that such a measurement may be realized in near future with help modern versions Michelson–Morley-type experiments.

(The vacuum is a medium is the message!) We use arguments taken from the electrodynamics of media to deduce the QCD trace anomaly from the expression for the vacuum energy in the presence of an external color magnetic field. Intuitive discussions of phenomena in quantum field theory frequently take the form of describing them as properties of the vacuum. The vacuum, it is then argued, is just l...
