TL;DR: In this article, the authors discuss what it is to teach a child to be critical, and how to tell whether we have been successful in doing so, and what kind of critical education is needed.
Abstract: What is it to teach a child to be critical, and how can we tell whether we have been successful in doing so? Is it a matter of imparting facts, of inculcating habits, of training in skills, of developing capacities, of forming the character, or something different from any of these?

TL;DR: In this article, a code conversion system that takes direction into consideration when converting characters from a source character encoding to a target character encoding is disclosed, which is able to map a single source character or sequence of characters to either a single target character or a sequence of target characters.
Abstract: A code conversion system that takes direction into consideration when converting characters from a source character encoding to a target character encoding is disclosed. The code conversion system is able to map a single source character or a sequence of characters to either a single target character or a sequence of target characters. By determining or resolving the direction of the characters being converted, the code conversion system can then utilize the determined or resolved direction of the characters to ensure that the correct mapping to the target character encoding is obtained.

TL;DR: In this article, a character recognition and communication system is proposed, where a character appearing on a document is converted into a character image signal at a transmission terminal including, for example, a facsimile scanner and transmitted to the prescribed center, after the character represented by the image signal is identified by a communication network including switching equipment.
Abstract: A character recognition and communication system, wherein a character appearing on a document is converted into a character image signal at a transmission terminal including, for example, a facsimile scanner and transmitted to the prescribed center, after the character represented by the image signal is identified by a communication network including switching equipment; the communication network comprises a plurality of switching units, and the corresponding recognition control units and character recognition units all scattered throughout said network and connected together by a common interconnection circuit; and the plural character recognition units recognize characters by different processes, have a complementary relationship with each other and recognize with high precision various kinds of characters supplied from a plurality of terminals and transmit the recognized characters to the corresponding centers.

TL;DR: It is proved that under reasonable assumptions, every cat (compact abstract theory) is metric, and some of the theory of metric cats is developed.
Abstract: We prove that under reasonable assumptions, every cat (compact abstract theory) is metric, and develop some of the theory of metric cats. We generalise Morley's theorem: if a countable Hausdorff cat T has a unique complete model of density character λ ≥ ω₁, then it has a unique complete model of density character λ for every λ ≥ ω₁.
