The article deals with problems of standard epistemic logics with a special at- tention to the context of scientific reasoning and to the problem of logical omniscience. The authors discuss various solutions of these problems and propose a new one based on the framework of substructural logics., Článek se zabývá problematikou standardní epistemické logiky se zvláštním zřetelem na kontext vědeckého uvažování a na problém logické vševědoucnosti. Autoři rozebírají různá řešení těchto problémů a navrhují nové řešení založené na struktuře substrukturální logiky., and Ondřej Majer ; Michal Peliš
In this paper the author provides a brief sketch of an interpretative turn in legal philosophy. In Law’s Empire, Ronald Dworkin advances a new theory of law, complex and intriguing. He calls it law as integrity. Dworkin’s conception of legal philosophy consists not in regarding its task as interpretive, for he advances the problem of what he dubbs the ''semantic sting''. The argument purports to establish the thesis that a theory of law cannot be an explanation of the meaning of the word ''law''. He claims that legal theories like H. L. A. Hart’s theory of law cannot explain the theoretical disagreement in legal practice, because they suffer from this semantic sting. The author agrees with Dworkin that Hart’s explanation of law is stung by semantics. It is his Dworkin’s main argument to deny that there is a possible alternative to his way of conceiving the task of legal philosophy. The author argues that the importance of Dworkin’s interpretative turn is not that it provides a substitute for ''semantic theories of law'', but that it provides a new conception of jurisprudence. and Marek Neština
Ponded infiltration experiment is a simple test used for in-situ determination of soil hydraulic properties, particularly saturated hydraulic conductivity and sorptivity. It is known that infiltration process in natural soils is strongly affected by presence of macropores, soil layering, initial and experimental conditions etc. As a result, infiltration record encompasses a complex of mutually compensating effects that are difficult to separate from each other. Determination of sorptivity and saturated hydraulic conductivity from such infiltration data is complicated. In the present study we use numerical simulation to examine the impact of selected experimental conditions and soil profile properties on the ponded infiltration experiment results, specifically in terms of the hydraulic conductivity and sorptivity evaluation. The effect of following factors was considered: depth of ponding, ring insertion depth, initial soil water content, presence of preferential pathways, hydraulic conductivity anisotropy, soil layering, surface layer retention capacity and hydraulic conductivity, and presence of soil pipes or stones under the infiltration ring. Results were compared with a large database of infiltration curves measured at the experimental site Liz (Bohemian Forest, Czech Republic). Reasonably good agreement between simulated and observed infiltration curves was achieved by combining several of factors tested. Moreover, the ring insertion effect was recognized as one of the major causes of uncertainty in the determination of soil hydraulic parameters.
