In this paper we study categories of theories and interpretations. In these categories, notions of sameness of theories, like synonymy, bi-interpretability and mutual interpretability, take the form of isomorphism. We study the usual notions like monomorphism and product in the various theories. We provide some examples to separate notions across categories. In contrast, we show that, in some c...

Assessing the driver’s cognitive load has become an increasing research interest. Methods described in literature fall into three categories: self-assessment, physiological measures, and performance-based measures. We claim that cognitive load can also be deducted by environmental factors, such as visual complexity of the context or driving speed. This paper describes an experiment aimed at bac...

The two- and three-syllable reduplicative babbling of five French-learning and five English-learning infants (0;5 to 1;1) was examined in two ways for intonational differences. The first measure was a categorization into one of five categories (RISING, FALLING, RISE-FALL, FALL-RISE, LEVEL) by expert listeners. The second was the fundamental frequency (F0) from the early, middle and late portion...

We investigate the structure of the Tukey types of ultrafilters on countable sets partially ordered by reverse inclusion. A canonization of cofinal maps from a p-point into another ultrafilter is obtained. This is used in particular to study the Tukey types of p-points and selective ultrafilters. Results fall into three main categories: comparison to a basis element for selective ultrafilters, ...

Boyer coined the term "scholarship of teaching", but the term has become ambiguous. In this paper, I nominate my own three categorizations of university computing educators: amateurs, students, and researchers. Amateurs may be excellent with students, but they do not routinely engage in dialog with other teachers about teaching. Students embrace the general theories of education, and write pape...

This study examines the instructional activities that underlie achievement in science using data from the TIMSS-R database. The focus population for this study is 15-yearold students from Cyprus. The results revealed a number of variables that were found to be negatively correlated with achievement as well as variables that were positively correlated with achievement. It appears that the negati...

1-In this paper, we examine the problem of address interworking that arises when two networks of the same type (that use the same addressing format) are interconnected by a different type of network (one that uses a different addressing format). Solutions to this problem fall broadly into four categories: (i) schemes that send address resolution messages when a call/packet arrives (" pull " inf...

The general question that forms the background to this paper is one that has interested many scholars over the years, including linguists, psychologists, philosophers, and others. This question concerns the role of our experiences in motivating features of language. A number of influential studies have proposed that certain categories of experiences—or their cognitive representations—are partic...
