Two kinds of logics are presented. Those of the first kind offer a maximally consistent interpretation of the premise set in as far as this is possible in view of logical considerations. At the same time, they indicate at which points further choices may be made on extra-logical grounds. The logics of the second kind allow one to introduce those choices in a defeasible way and handle them.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Meheus, Joke</style></author><author><style face="normal" font="default" size="100%">De Clercq, Kristof</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Goal-Directed Tableaux</style></title><secondary-title><style face="normal" font="default" size="100%">The Many Sides of Logic</style></secondary-title><tertiary-title><style face="normal" font="default" size="100%">Studies in Logic</style></tertiary-title></titles><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><publisher><style face="normal" font="default" size="100%">College Publications</style></publisher><pub-location><style face="normal" font="default" size="100%">London</style></pub-location><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">241–256</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;This paper contains a new format for analytic tableaux, called goal-directed tableaux.

The goal-directed tableaux do not form a complete decision method for propositional classical logic (because they do not sustain Ex Falso Quodlibet). For consistent sets of premises, however, they lead to the same results as the usual analytic tableaux for classical logic.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Primiero, Giuseppe</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Prioritized Dynamic Retraction Function on Non-monotonic Information Updates</style></title><secondary-title><style face="normal" font="default" size="100%">The Many Sides of Logic</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><publisher><style face="normal" font="default" size="100%">College Publications</style></publisher><pub-location><style face="normal" font="default" size="100%">London</style></pub-location><pages><style face="normal" font="default" size="100%">443-463</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;In this paper a model for updates on belief sets and retractions thereof is introduced using the standard format of Adaptive Logics. The core of the update retraction procedure is represented by abnormal expressions derivable in the language: they express updates with information con- tradicting previously derived contents. The adaptive strategy aims at restricting the validity of these formulas by focusing at each decreasing degree on the update which is the most rational to retract in order to re- store consistency as soon as possible. This work is related to the standard operations of retraction and withdrawal from the AGM-paradigm and the eects of dynamic operations such as public announcement in Dynamic Epistemic Logic.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Provijn, Dagmar</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Strategies: what's in a name?</style></title><secondary-title><style face="normal" font="default" size="100%">The Many Sides of Logic</style></secondary-title><tertiary-title><style face="normal" font="default" size="100%">Studies in Logic</style></tertiary-title></titles><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><publisher><style face="normal" font="default" size="100%">College Publications</style></publisher><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">287–306</style></pages><isbn><style face="normal" font="default" size="100%">9781904987789</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;In this paper, I will show that Hintikkas notion of strategy can refer to proof-heuristic reasoning as well as to methodological reasoning forms.

Contrary to Hintikkas opinion, heuristic reasoning can be implemented in formal proofs by means of goal-directed proof procedures. Methodological reasoning forms on the other hand can be formally represented by means of adaptive logics.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Meheus, Joke</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">An Adaptive Logic for Pragmatic Truth</style></title><secondary-title><style face="normal" font="default" size="100%">Paraconsistency.

APT has the peculiar property that it enables one to interpret a (possibly inconsistent) theory Gamma 'as pragmatically as possible'. The aim is to capture the idea of a partial structure (in the sense of da Costa and associates) that adequately models a (possibly inconsistent) set of beliefs Gamma. What this comes to is that APT localizes the 'consistent core' of Gamma, and that it delivers all sentences that are compatible with this core. For the core itself, APT is just as rich as Classical Logic. APT is defined from a modal adaptive logic APV that is based itself on two other adaptive logics. I present the semantics of all three systems, as well as their dynamic proof theory. The dynamic proof theory for APV is unusual (even within the adaptive logic programme) in that it incorporates two different kinds of dynamics.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Vermeir, Timothy</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">An Inconsistency-Adaptive Proof Procedure for Logic Programming</style></title><secondary-title><style face="normal" font="default" size="100%">Paraconsistency.

This assumption results in the fact that people usually do not make any distinction between 'the object a' and 'the object a at a given moment'. This laziness causes many inconsistencies. Several attempts to solve these inconsistencies are studied, and the most natural one is elaborated, namely the one obtained by applying Classical Logic to an ontological correct domain. This solution has a drawback with respect to communication, which is solved by the change-adaptive logic CAL2. This non-monotonic, paraconsistent logic, belongs to the family of ambiguity-adaptive logics. It has the special characteristic that it solves inconsistencies by the introduction of more precise names for objects, more exactly names that refer to objects at a moment. The dynamics of the logic captures the change in objects. CAL2 has a nice proof theory, and an intuitive semantics. Interesting results and applications are commented upon, for instance those making use of the notion 'periods of invariance'. Of course, the philosophical background is discussed.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Batens, Diderik</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">On some Remarkable Relations between Paraconsistent Logics, Modal Logics, and Ambiguity Logics</style></title><secondary-title><style face="normal" font="default" size="100%">Paraconsistency.

First, a paraconsistent logic &lt;strong&gt;A&lt;/strong&gt; is presented that has the same expressive power as &lt;strong&gt;S5&lt;/strong&gt;. Next, I consider the definition of paraconsistent logics from &lt;strong&gt;S5&lt;/strong&gt; and &lt;strong&gt;AL&lt;/strong&gt;. Such definition is shown to work for some logics, for example Priest's &lt;strong&gt;LP&lt;/strong&gt;. Other paraconsistent logics appear to withstand such definition, typically those that contain a detachable material implication. Finally, I show that some paraconsistent logics and inconsistency-adaptive logics serve exactly the same purpose as some modal logics and ampliative adaptive logics based on &lt;strong&gt;S5&lt;/strong&gt;. However, they serve this purpose along very different roads and the logics cannot be defined from one another.&lt;br /&gt;&lt;br /&gt; The paper intends to open lines of research rather than pursuing them to the end. It also contains a poor person's semantics for &lt;strong&gt;S5&lt;/strong&gt; as well as a description of the simple but useful and powerful &lt;strong&gt;AL&lt;/strong&gt;.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Marcos, João</style></author><author><style face="normal" font="default" size="100%">Loffredo D'Ottaviano, Itala M.</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Carnielli, Walter A.</style></author><author><style face="normal" font="default" size="100%">Coniglio, Marcelo E.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">A taxonomy of C-systems</style></title><secondary-title><style face="normal" font="default" size="100%">Paraconsistency.
