Classical logic argumentation (Cl-Arg) under the stable semantics yields argumentative characterisations of non-monotonic inference in Preferred Subtheories. This paper studies these characterisations under both the standard approach to Cl-Arg, and a recent dialectical approach that is provably rational under resource bounds. Two key contributions are made. Firstly, the preferred extensions are shown to coincide with the stable extensions. This means that algorithms and proof theories for the admissible semantics can now be used to decide credulous inference in Preferred Subtheories. Secondly, we show that as compared with the standard approach, the grounded semantics applied to the dialectical approach more closely approximates sceptical inference in Preferred Subtheories.

Philosophical Writings

John Locke, long associated with the “standard” approach to fallacies and the “logical” approach to valid inference, had both logical and dialectical reasons for favoring certain proofs and denigrating others. While the logical approach to argumentation stands forth in Locke’s philosophical writings (such as the Essay Concerning Human Understanding), a dialectical approach can be found in his contributions to public controversies regarding religion and toleration. Understanding Locke’s dialectical approach to argumentation not only makes his work more relevant to the contemporary discipline of informal logic, but this understanding also prompts a reconsideration of Locke’s rhetorical purpose. He approached argumentation dialectically (and logically) because he wanted to appeal to a universal audience of free rational subjects, people not unlike the real historical audience whom Locke addressed: radical Whigs, latitudinarian Anglicans, early-Enlightenment philosophes.

Modern Perspective

Back in the late 1950s, C.P. Snow famously defined science negatively by separating it from what it was not, namely literature. Such polarization, however, creates more problems than it solves. By contrast, the two co-editors of the book have adopted a dialectical approach to the subject, and to the numerous readers who keep asking themselves “what is science?”, we provide an answer from an early modern perspective, whereby “science” actually includes such various intellectual pursuits as history, poetry, occultism, or philosophy. Each essay illustrates one particular aspect of Shakespeare’s works and links science with the promise of the spectacular. This volume aims at bridging the gap between Renaissance literature and early modern science, focusing as it does on a complex intellectual territory, situated at the point of juncture between humanism, natural magic and craftsmanship. We assume that science and literature constantly interacted with one another, making clear the fact that what we now call “literature” and what we choose to see as “science” were not clearly separated in Shakespeare’s days but rather part of a common intellectual territory.

Subject. This article explores the main points of the theory of financial management, developed within the framework of the Western general theory of finance, and the theory of financial management developed in the Soviet Union. Objectives. The article aims to substantiate an idea that these theories are complementary, and their harmonious application can help build the most effective system of financial relations management at both the macro-and microeconomic levels. Methods. For the study, I used a dialectical approach and the methods of comparison, analysis and synthesis, and historical analysis. Results. The article substantiates the point that the methodology of Western financial management theory is aimed at managing external financial flows and combating external financial risks. It notes that the Soviet theory regulates methods and techniques of financial management within the business entity or the State. Conclusions. Theoretical updating of the Soviet practices of financial management combined with the modern achievements of financial management theory will create conditions for the formation of an optimal financial management structure at both the micro-and macroeconomic levels. This can improve the efficiency of financial management, in general. Renewed interest in the theoretical developments of the Soviet Union will contribute to the development of financial science at the present stage.

Inherent Tendency

Bipolar abstract argumentation frameworks allow modeling decision problems by defining pro and contra arguments and their relationships. In some popular bipolar frameworks, there is an inherent tendency to favor either attack or support relationships. However, for some applications, it seems sensible to treat attack and support equally. Roughly speaking, turning an attack edge into a support edge, should just invert its meaning. We look at a recently introduced bipolar argumentation semantics and two novel alternatives and discuss their semantical and computational properties. Interestingly, the two novel semantics correspond to stable semantics if no support relations are present and maintain the computational complexity of stable semantics in general bipolar frameworks.

Gas Selectivity

Control of pore window size is the standard approach for tuning gas selectivity in porous solids. Here, we present the first example where this is translated into a molecular porous liquid formed from organic cage molecules. Reduction of the cage window size by chemical synthesis switches the selectivity from Xe-selective to CH<sub>4</sub>-selective, which is understood using <sup>129</sup>Xe, <sup>1</sup>H, and pulsed-field gradient NMR spectroscopy.
