The paper proposes a new perspective on modelling ad hominem (AH) techniques in a dialogue. The approach is built upon the following assumptions: (i) that ad hominem is not an inferential, but undercutting structure; (ii) that it can be a non-fallacious dialectical technique in some communicative contexts; and (iii) that critical questions in Walton’s AH scheme can be used to determine strategi...

A study was carried out of monocular disc photographs from 33 eyes for which the visual fields on both static profile and kinetic perimetry has been performed. Physical signs looked for at the optic disc included thinning of the neuroretinal rim, angulation of retinal vessels, extension of laminar dots, undercutting of the neuroretinal rim, and absence and pallor of the neuroretinal rim. These ...

Using a model of dynamic price competition, this paper provides an explanation from the supply side for the well-established observation that retail prices adjust faster when input costs rise than when they fall. The opportunity of profitable storing for the next period induces competitive firms to immediately increase their prices in anticipation of higher future input costs. This relaxes comp...

In this article we offer a formal account of reasoning with legal cases in terms of argumentation schemes. These schemes, and undercutting attacks associated with them, are formalized as defeasible rules of inference within the ASPIC+ framework. We begin by modelling the style of reasoning with cases developed by Aleven and Ashley in the CATO project, which describes cases using factors, and th...

We show that equilibrium involuntary unemployment emerges in a multi-stage game model where all market power resides with firms, on both the labour and the output market. Firms decide wages, employment, output and prices, and under constant returns there exists a continuum of subgame perfect Nash equilibria involving unemployment and positive profits. A firm does not undercut the equilibriumwag...

Three times as many cases of measles were reported in the United States in 2014 as in 2013. The reemergence of measles has been linked to a dangerous trend: parents refusing vaccinations for their children. Efforts have been made to counter people's antivaccination attitudes by providing scientific evidence refuting vaccination myths, but these interventions have proven ineffective. This study ...

Two essential elements of free will—internal locus of control and confident self-efficacy—have been studied extensively by psychologists but neglected by philosophers. As a result of this neglect, philosophers have worked with a distorted view of free will. Existentialists exaggerate internal locus of control while undercutting self-efficacy; most contemporary philosophers have taken both inter...

A multi-state latching translation stage is demonstrated using microelectromechanical systems technology. The mechanism is fabricated in bonded silicon-on-insulator material with an 85 μm thick bonded layer, by single-layer patterning, deep reactive ion etching, undercutting and metallization. The table position can be continuously adjusted by electrothermal buckling mode actuators or latched i...
