Abstract Elay Shech and John Earman have recently argued that the common topological interpretation of the Aharonov–Bohm (AB) effect is unsatisfactory because it fails to justify idealizations that it presupposes. In particular, they argue that an adequate account of the AB effect must address the role of boundary conditions in certain ideal cases of the effect. In this paper I defend the topological interpretation against their criticisms. I consider three types of idealization that might arise in treatments of the effect. First, Shech takes the AB effect to involve an idealization in the form of a singular limit, analogous to the thermodynamic limit in statistical mechanics. But, I argue, the AB effect itself features no singular limits, so it doesn’t involve idealizations in this sense. Second, I argue that Shech and Earman’s emphasis on the role of boundary conditions in the AB effect is misplaced. The idealizations that are useful in connecting the theoretical description of the AB effect to experiment do interact with facts about boundary conditions, but none of these idealizations are presupposed by the topological interpretation of the effect. Indeed, the boundary conditions for which Shech and demands justification are incompatible with some instances of the AB effect, so the topological interpretation ought not justify them. Finally, I address the role of the non-relativistic approximation usually presumed in discussions of the AB effect. This approximation is essential if—as the topological interpretation supposes—the AB effect constrains and justifies a relativistic theory of the electromagnetic interaction. In this case the ends justify the means. So the topological view presupposes no unjustified idealizations.

Dispositional Properties

This chapter develops a suggestion of Nelson Goodman that one should see the problem of explaining dispositional predicates and the problem of constructing an adequate theory of confirmation as aspects of the same underlying problem. It is argued that projectivism—the strategy of connecting rules of inductive practice with the development of theoretical descriptive concepts—does not imply quasi-realism, but is compatible with a thoroughly realistic understanding of those concepts. After a general discussion of the role of dispositional properties, the chapter looks in more detail at one kind of dispositional theory—a propensity account of objective chance—where the conceptual connection between concepts for giving a theoretical description of the world and rules of inductive practice is particularly explicit.

Abstract Structure

More than thirty years ago I wrote a book called Inquiry. This was a great title for a philosophy book, with its allusion (or homage) to classic works in the empiricist tradition, and it was an appropriate title for the aspirations with which the book was written: its topic, I said in the preface, was the abstract structure of inquiry. But it is less clear that this was an appropriate title for what was actually accomplished in the book since it did not get much beyond preliminary setting up of the issues, and some exposition of and motivation for the formal apparatus that I planned to use to talk about the structure of inquiry. Before getting to the main issues, I had to explain and motivate my approach to the problem of intentionality, sketch and motivate the formal apparatus used to represent that approach (possible worlds semantics), and respond to problems that the approach faced. That took up most of the book. The rest of it focused mainly on another piece of apparatus needed to represent the dynamics of belief (a formal semantics for conditionals), and I was able to make only a start on a discussion of the role of this apparatus in forming and refining both rules for revising beliefs, and concepts for giving a theoretical description of the world....

The paper discusses the importance of rural tourism and sustainable rural areas development. It highlights the role of tourism in dealing with problems of rural areas and agriculture sector in the Czech Republic. After theoretical description of a system approach to rural tourism development, the author continues by a practical part where she compares tourism and agrotourism management in the Czech Republic and Austria. Austria has been chosen as a representative of a state with developed tourism system and tourism management. Selected aspects of management systems are then compared and proposed for improvement in tourism/agrotourism. Critical key factor for successful development of activities in rural areas (therefore including agrotourism services) are then presented.
