Functions are all around us, disguised as actions on concrete objects. Composition of functions, too, is all around us, because these actions can be performed in succession, the output of one serving as the input for the next. In terms of Gray and Tall's (2001) "embodied objects" or Lakoff and Nunez's (2000) "mathematical idea…

An extensive literature has emerged in the past decade that examined financial reporting in a digital environment. This study extends this literature by examining the factors that may influence the preference of a digital presentation format. Using questionnaire design, this study examines whether public accounting practitioners' work experience…

Radio broadcasting offers a unique opportunity to reach the public and facilitate their entertainment and education. In this vein, a series of high profile lectures in honour of Sir John Reith was initiated by the BBC in 1948 as a way of introducing the public to some of the greatest scientists of the age, enabling such thinkers to spread a…

In 1998, Nancy Pearl and Chris Higashi, librarians working in the Washington Center for the Book at the Seattle Public Library (SPL), had a brainstorm. Challenged with a grant to develop new audiences for literature, they were intrigued with the power of books to unite diverse audiences. With that in mind, they expanded the book club concept to…

In this article, the author provides several reasons why one should not rewrite a code from scratch. One should not do it because it will take longer than one thinks. This is the lesson he learned when he started rewriting one of his applications from scratch. The sane thing to do would have been to fix or replace a piece and get on with life.…

Sixteen scholarly papers and twenty abstracts comprise the content of the eighteenth annual Brick & Click Libraries Conference, held annually at Northwest Missouri State University in Maryville, Missouri. The proceedings, authored by academic librarians and presented at the conference, portray the contemporary and future face of librarianship.…

The Association Supporting Computer Users in Education (ASCUE) is a group of people interested in small college computing issues. It is a blend of people from all over the country who use computers in their teaching, academic support, and administrative support functions. Begun in 1968 as the College and University Eleven-Thirty Users' Group…

Dynamic programming methods for matrix permutation problems in combinatorial data analysis can produce globally-optimal solutions for matrices up to size 30x30, but are computationally infeasible for larger matrices because of enormous computer memory requirements. Branch-and-bound methods also guarantee globally-optimal solutions, but computation…

The determination of bounds for A(n, d, w), the maximum possible number of binary vectors of length n, weight w, and pairwise Hamming distance no less than d, is a classic problem in coding theory. Such sets of vectors have many applications. A description is given of how the problem can be used in a first-year undergraduate computational…

Each year the ACM hosts a truly international programming contest--the International Collegiate Programming Contest (ICPC). Dating back to a contest held by Texas A&M University in 1970, this annual event, along with the associated regional contests, has grown to 5606 teams from 1733 universities in 84 countries (in the year 2006). Despite the…

We discuss the design, creation and implementation of an instructional game for use in a high school poetry class following a commitment to an educational game design principle of "alignment". We studied groups of instructional designers and an interactive fiction computer game they built. The game was implemented in a 9th grade English classroom…

This article critiques learning design as a representation for sharing and developing practice, based on synthesis of three projects. Starting with the findings of the Mod4L Models of Practice project, it argues that the technical origins of learning design, and the consequent focus on structure and sequence, limit its usefulness for sharing…

The potential influence of violent video games on youth violence remains an issue of concern for psychologists, policymakers and the general public. Although several prospective studies of video game violence effects have been conducted, none have employed well validated measures of youth violence, nor considered video game violence effects in…

In the 21st century, the ubiquitous nature of technology today is evident and to a large extent, most of us benefit from the modern convenience brought about by technology. Yet to be technology literate, it is argued that learning to program still plays an important role. One area of research in programming concerns the identification of…

The residue number system (RNS) has been an important research field in computer arithmetic for many decades, mainly because of its carry-free nature, which can provide high-performance computing architectures with superior delay specifications. Recently, research on RNS has found new directions that have resulted in the introduction of efficient…
