Commentary on Jan Albert van Laar and Erik C. W. Krabbe, “Splitting a Difference of Opinion”

Ambiguity in a dialectical perspective

About Old and New Dialectic : Dialogues , Fallacies , and Strategies University of Groningen

In 1998, forty years after the original edition of The New Rhetoric (Perelman and Olbrechts-Tyteca, 1958), Douglas Walton published The New Dialectic. The title confirmed the dialectical turn of argumentation theory, taken long before. Both titles refer to old versions of practices and theories, a new dialectic presupposing an old dialectic as much as a new rhetoric presupposes an old rhetoric....

Investigating Different Methods of Closed Shell Pistachios Splitting and Effects of Freezing Prior to Drying on Shell Splitting Percentage

In this study, different methods for shell splitting and the effect of freezing prior to drying on shell splitting percentage of pistachio were investigated. A completely randomized design was used to investigate the effects of different freezing temperatures (0, -6, -12 and -18°C), different drying temperatures (80, 90 and 100°C) and different cultivars (Akbari and Kalehghouchi) on shell split...

One-Sided Arguments

When is an argument to be called one-sided? When is putting forward such an argument fallacious? How can we develop a model for critical discussion, such that a fallaciously one-sided argument corresponds to a violation of a discussion rule? These issues are dealt with within ‘the limits of the dialogue model of argument’ by specifying a type of persuasion dialogue in which an arguer can offer ...

Numerical Investigation on Compressible Flow Characteristics in Axial Compressors Using a Multi Block Finite Volume Scheme

An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...
