Robo-Sensei's NLP system includes a lexicon, a morphological generator, a word segmentor, a morphological parser, a syntactic…

This paper shows the basic concept of Functional Modelling in mathematics education which has become more and more important in recent years. Hence it is necessary to think about suitable graphical methods to explain the fundamental idea of a function and its influence on values and other functions. PROGRAPH diagrams are a potentially good way to…

This article addresses issues surrounding critical media literacy using popular culture texts. The authors focus on the example of their work with a fourth-grade class involved in a project to unpack the messages of popular media and advertising texts.

Games are widely recognized for their potential to enhance students' learning. Yet they are only rarely used in classrooms because they cannot be modified to meet the needs of a particular class. This article describes a novel approach to creating educational software that addresses this problem: provide an interface specifically for teachers that…

Shows how e-mail users have evolved new forms of electronic deictic references to refer to work objects and offers design suggestions for future electronic mail software. Highlights include a study of e-mail work conversations; and changing the way we talk by transforming the conversation itself into an object of conversation. (Author/LRW)

Uses a sample data set to describe in nonmathematical terms how to implement and interpret results from a best-subsets logistic regression using the Statistical Analysis System. (SLD)

Presents a latent class extension of signal detection theory and illustrates applications of this approach. Introduces an extension of the signal detection model to more than two latent classes, with a simple restriction on the detection parameters and provides some sample programs to fit the models. (SLD)

Illustrates that the Benjamini-Hochberg (B-H) procedure to controlling the false positive rate in multiple comparisons is easy to implement using widely available spreadsheet software. Shows that it is feasible to use the B-H procedure to augment or replace the Bonferroni technique. (SLD)

Describes the University of New Mexico's photo identification LOBO card system, which performs both security and validation tasks. It is used in conjunction with several C-CURE 800 Integrated Security Management Systems supplied by Software House of Lexington, Massachusetts. (EV)

Describes the programming interface and implementation of the repository engine and the Open Information Model for Microsoft Repository, an object-oriented meta-data management facility that ships in Microsoft Visual Studio and Microsoft SQL Server. Discusses Microsoft's component object model, object manipulation, queries, and information…

Introduces the problem of hierarchical, or nested, data structures and discusses how this problem is dealt with effectively. Provides examples of the pitfalls of not doing appropriate analyses. New software is making hierarchical linear modeling more user-friendly and accessible. (SLD)

Discusses the mobile software agent paradigm that provides a foundation for the development of high performance distributed applications and presents a simple, distributed access control architecture based on the concept of distributed, active authorization entities (lock cells), any combination of which can be referenced by an agent to provide…

In the last year, a series of viruses and worms that caused damage across the Internet in record time has made very clear how vulnerable computer systems are. The MS Blaster, Slammer, Sasser, and Korgo.W worms have shown that signature-based antivirus software and traditional firewalls are not enough to protect networks. Everyone is worried about…

Standard Microsoft Excel functions and the Excel Data Table facility are used in randomization applications using resampling with and without replacement.
