Purpose: The purpose of this paper is two-fold: (1) to build a theoretical model that identifies textual cues to distinguish between authentic and fictitious reviews, and (2) to empirically validate the theoretical model by examining reviews of positive, negative as well as moderate polarities. Design/methodology/approach: Synthesizing major theories on deceptive communication, the theoretical ...

This paper presents a contribution to the debates surrounding the culpability of accounting in the recent financial crisis. It adopts a Marxist theoretical perspective concentrating mainly on Marx’s work on fictitious capital. Fictitious capital is any form of investment (for example bonds, stocks, derivatives, and collateralized debt obligations) which is based upon the expectation of future r...

CONTEXT Student evaluations of teaching (SETs) inform faculty promotion decisions and course improvement, a process that is predicated on the assumption that students complete the evaluations with diligence. Anecdotal evidence suggests that this may not be so. OBJECTIVES We sought to determine the degree to which medical students complete SETs deliberately in a classroom-style, multi-instruct...

In this paper we study two possible semantics for the real-time logic MTL (Metric Temporal Logic). In the rst semantics, called dense time semantics, time is modeled by the positive real numbers. In the second one, called ctitious clock semantics, real-time information is delivered by a global ctitious clock. We show that the ctitious clock semantics can be viewed as an abstraction of the dense...

A generalization is presented here for a newly developed approach to ab initio molecular dynamics, where the density matrix is propagated with Gaussian orbitals. Including a tensorial fictitious mass facilitates the use of larger time steps for the dynamics process. A rigorous analysis of energy conservation is presented and used to control the deviation of the fictitious dynamics trajectory fr...

Distributed optimisation can be formulated as an n player coordination game. One of the most common learning techniques in game theory is fictitious play and its variations. However fictitious play is founded on an implicit assumption that opponents’ strategies are stationary. In this paper we present a new variation of fictitious play in which players predict opponents’ strategy using a partic...

Continuous action space games form a natural extension to normal form games with finite action sets. However, whilst learning dynamics in normal form games are now well studied, it is not until recently that their continuous action space counterparts have been examined. We extend stochastic fictitious play to the continuous action space framework. In normal form games the limiting behaviour of ...
