We prove the impossibility of recent attempts to decouple the Replica Symmetry Breaking (RSB) picture for finite-dimensional spin glasses from the existence of many thermodynamic (i.e., infinite-volume) pure states while preserving another signature RSB feature — space filling relative domain walls between different finite-volume states. Thus revisions of the notion of pure states cannot shield...

Most areas of health research will have accepted data and a dominating interpretation. If the interpretation is not correct, contradictions will accumulate, and it will eventually become clear that the current interpretation is untenable. In this situation, the best hypothesis is the one that accounts for all of the known data as well as the apparent contradictions. The area of vitamin A supple...

We study deduction in the presence of inconsistencies. Following previous works, we capture deduction via datalog programs and inconsistencies through violations of functional dependencies (FDs). We study and compare two semantics for datalog with FDs: the first, of a logical nature, is based on inferring facts one at a time, while never violating the FDs; the second, of an operational nature, ...

In this note I say a few words about my interaction with the late Hartley Slater and his work. Si on appelle un chat un chat Cela évite les embrouilles Et on retombe toujours sur ses pattes Baron de Chambourcy 1 From Los Angeles to Helsinki: 20 years of friendship Barry Hartley Slater recently died (July 8, 2016). We are publishing in this issue of the South American Journal of Logic the paper ...

No one seriously concerned with political strategies in the current situation can now afford to ignore the "swing to the Right". We may not yet understand its extent and its limits, its specific character, its causes and effects. We have so far—with one or two notable exceptions—failed to find strategies capable of mobilizing social forces strong enough in depth to turn its flank. But the tende...

Introduction Dialectical contradictions, as conceptualized in Cultural-Historical Activity Theory (CHAT), can be used fruitfully as an analytical tool in order to study organizational change associated with the introduction of new technologies (Groleau, Demers, Lalancette, & Barros, 2011). Drawing from the work done by Engeström and Sannino (2011), this paper aims to contribute to the operation...

nowadays, discussion about and analysis of ṣiḥḥa (truth) and fasād (falsehood) is a focus of attention in theological (uṣūlī) writings. this issue necessitates an explanation of the present structure of the discourse of ṣiḥḥa and fasād in an integrated and logical way. thereby, to achieve this important task, the present article undertakes a descriptive-analytical research based on a library-me...

When it comes to understanding the dynamics of interaction between humans and technology, activity theory's principle of contradiction is very useful. This is because contradictions expose links between humans and technology. These links are in form of problems, ruptures, breakdowns, clashes, distortions and so on. In this paper, we used activity theory's principle of contradiction to analyze r...
