In current Peer-to-Peer networks, distributed and semantic free indexing is widely used by systems adopting "Distributed Hash Table" ("DHT") mechanisms. Although such systems typically solve a. user query rather fast in a deterministic way, they only support a very narrow search scheme, namely the exact hash key match. Furthermore, DHT systems put…

In order to compete in a global environment, Malaysian business firms need to improve their products and services through best practices. This paper aims to investigate the critical success factors to adopt Enterprise Resource Planning (ERP) with knowledge management (KM) strategies among Malaysian business firms. In order to achieve the research…

Readily available software designed for the production of music can be adapted easily to the physics classroom. Programs such as Apple's GarageBand access large libraries of recorded sound waves that can be heard and displayed both before and after alterations. Tools such as real-time spectral analysers, digital effects, and audio file editors…

Recognizing the failures of traditional Technology Enhanced Learning (TEL) initiatives to achieve performance improvement, we need to rethink how we design new TEL models that can respond to the learning requirements of the 21st century and mirror the characteristics of knowledge and learning which are fundamentally personal, social, distributed,…

The increasing popularity of R is leading to an increase in its use in undergraduate courses at universities (R Development Core Team 2008). One of the strengths of R is the flexible graphics provided in its "base" package. However, students often run up against its limitations, or they find the amount of effort to create an interesting plot may…

This paper describes the creation and early uses of Logo. It includes a brief summary of more recent work on Logo-derived languages and learning applications. It closes with a lament on the unrealized potential of student programming languages as empowering tools for knowledge construction and learning.

Back in the 1990s, enterprise resource planning (ERP) systems may not have been user-friendly, but what they tried to do was totally reasonable: replace stand-alone systems in various departments--such as finance, logistics, and human resources--with a single integrated software program. The idea was that although each department would still have…

Nuclear magnetic resonance (NMR) poses significant challenges for teaching in the context of an undergraduate laboratory, foremost because of high equipment cost. Current off-the-shelf data-acquisition hardware, however, is sufficiently powerful to constitute the core of a fully digital NMR spectrometer operating at the earth's field. We present…

DataToText is a project developed where the user communicates the relevant information for an analysis and DataToText computer routine produces text output that describes in words, tables, and figures the results from the analyses. Two extended examples are given, one an example of a moderator analysis and the other an example of a dyadic data…

This article discusses the benefits of screencasts and its instructional uses. Well-known for some years to advanced technology users, Screen Capture Software (SCS) offers the promise of recording action on the computer desktop together with voiceover narration, all combined into a single movie file that can be shared, emailed, or uploaded.…

Feedback on students' work is, probably, one of the most important aspects of learning, yet students' report, according to the National Union of Students (NUS) Survey of 2008, unhappiness with the feedback process. Students were unhappy with the quality, detail and timing of feedback. This paper examines the benefits of using audio, as opposed to…

This article reviews how current social network analysis might be used to investigate individual and group behavior in sporting teams. Social network analysis methods permit researchers to explore social relations between team members and their individual-level qualities simultaneously. As such, social network analysis can be seen as augmenting…

Computer literacy plays a critical role in today's life sciences research. Without the ability to use computers to efficiently manipulate and analyze large amounts of data resulting from biological experiments and simulations, many of the pressing questions in the life sciences could not be answered. Today's undergraduates, despite the ubiquity of…

Solid modeling is widely used as a teaching tool in summer activities with high school students. The addition of motion analysis allows concepts from statics and dynamics to be introduced to students in both qualitative and quantitative ways. Two sets of solid modeling projects--carnival rides and Rube Goldberg machines--are shown to allow the…

This paper documents several years of experimentation with a new approach to organizing and managing projects in a software engineering course. The initial failure and subsequent refinements that the new approach has been through since 2004 are described herein. The "constrained and guided" approach, as it is called, has helped to reduce…
