Digital storytelling embraces the art of traditional storytelling and reconfigures it using modern digital mediums. More specifically, "Digital storytelling is the practice of combining narrative with digital content, including images, sound, and video, to create a short movie, typically with a strong emotional component." There are a…

In this paper, we describe a Relational Algebra Query Language (RAQL) and Relational Algebra Query (RAQ) software product we have developed that allows database instructors to teach relational algebra through programming. Instead of defining query operations using mathematical notation (the approach commonly taken in database textbooks), students…

In this paper, multiple criteria optimization has been investigated. A new decision support system (DSS) has been developed for interactive solving of multiple criteria optimization problems (MOPs). The weighted-sum (WS) approach is implemented to solve the MOPs. The MOPs are solved by selecting different weight coefficient values for the criteria…

The major challenges facing resource constraint wireless devices are error resilience, security and speed. Three joint schemes are presented in this research which could be broadly divided into error correction based and cipher based. The error correction based ciphers take advantage of the properties of LDPC codes and Nordstrom Robinson code. A…

The purpose of this article is to describe a bunch of strategies with which teachers may already be familiar and, perhaps, use regularly, but not always in the context of a formal PowerPoint[R] presentation. Here are the author's top 10 engagement techniques that fit neatly within any version of PowerPoint[R]. Some of these may also be used with…

In this paper, we describe a new method we have developed for setting cut scores between levels of a test. We outline the wide variety of potential methods that have been used for such a process, and emphasize the need for a coherent conceptual framework under which the variety of methods could be understood. We then describe our particular…

According to a March estimate from Distimo, there were 653,614 apps in the iPhone, Android, iPad, BlackBerry, and Windows Mobile stores alone. So, is it any wonder that these busy people have found a few that come in handy on the job? Mobile apps are as indispensable to district IT executives as they are becoming in the classroom--for professional…

The Moffitt-Woodward-Moscowitz-Klyne-Djerassi octant rule is one of the most successful empirical rules in organic chemistry. However, the lack of a simple effective modeling method for the octant rule in the past 50 years has posed constant difficulties for researchers, teachers, and students, particularly the young generations, to learn and…

This article discusses how a special library can meet the needs of a specific industry. The author focuses on India's National Insurance Academy (NIA) Library, which serves the insurance industry of India and some neighboring countries. It is where the author serves as the chief librarian.

This paper describes how a linguistic form, rap, can evolve in tandem with technological advances and manifest human-machine creativity. Rather than assuming that the interplay between machines and technology makes humans robotic or machine-like, the paper explores how the pressure of executing artistic visions using technology can drive…

As virtualization becomes commonplace in higher education, it is clear that the traditional licensing options for software are woefully inadequate. The definitions of who is licensed to use what--and where--are blurring, as users move from physical to virtual spaces and can access software from a variety of devices. In discussing the need for new…

Whether one is on Wall Street, in Congress, or working in an IT shop on campus, negotiating a good deal is hard work. As higher education enters its purchasing season, "Campus Technology" talks to deal makers who have "been there and done that." This article presents their tips for getting the most value from vendors the next time one buys…

A very low-cost, easy-to-make stopwatch is presented to support various experiments in mechanics. The high-resolution stopwatch is based on two photodetectors connected directly to the microphone input of a sound card. Dedicated free open-source software has been developed and made available to download. The efficiency is demonstrated by a free…

This project represents an initial investigation into utilizing the two-dimensional Continuous Response Digital Interface (CRDI) to track listener perceptions related to the possible relationships between focus of attention to musical elements and perceived musical tension. The two-dimensional CRDI software creates an environment in which the…

Rating scale items have been widely used in educational and psychological tests. These items require people to make subjective judgments, and these subjective judgments usually involve randomness. To account for this randomness, Wang, Wilson, and Shih proposed the random-effect rating scale model in which the threshold parameters are treated as…
