The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.

Visualization Ability

In research on cognitive issues in automation, spatial visualization ability (SVA) was investigated as a mediator of performance. Prior to performing the experimental task in a simulation environment, 83 undergraduate psychology students completed an on-line version of a test of SVA. The two basic experimental conditions were “monitoring” and “on-call.” In the monitoring condition, participants monitored status messages and responded to system alerts. In the on-call condition, participants performed an unrelated task in between responding to alerts. Dependent measures included decision accuracy. A correlational analysis of SVA scores with decision accuracy found a higher correlation for men than for women. Further analysis indicated that SVA was not a significantly stronger predictor of performance for men than it was for women in the simulated environment. With a larger sample size, however, differential prediction is likely. If confirmed, this finding has implications for the use of SVA in personnel selection. Textual and tabular alternatives to graphical displays may be helpful to low-SVA users.

AbstractSUPERXAP (Super X-ray Analysis Program) enables IBM-compatible personal computers to analyze energy-dispersive spectra using least-squares spectral deconvolution. The program corrects for instrument drift, background, peak overlap, and matrix effects. Pull down menus provide 24 subroutines and functions, that allow spectra to be transferred, stored, viewed, manipulated, and analyzed. Spectral peaks can be identified manually or automatically with color-coded K, L or M lines. Working curves are developed using an interactive routine that creates standard files by least-squares fitting of peak intensities to known elemental abundances. Elemental abundances in unknowns may be determined in a variety of ways including on-line analysis of spectra as they are generated by an energy-dispersive detector and by batch analyses of spectra stored on disk. Standard deviation, based on counting statistics, is reported for each element in each analysis. Written in QuickBASIC 4.5 for interface with a KEVEX 7000 radioactive-source x-ray fluorescence analyzer, SUPERXAP could be adapted, with minor modification, to accept and analyze data from other instruments that produce energy-dispersive spectra.

The suitability of these indicators for the on-line estimation of network traffic self-similarity was investigated by applying computer-based modelling. The software SSE (Self-Similarity Estimator) module library was developed; it was designed for the recording and aggregation of network traffic packages as well as for the on-line estimation of network traffic self-similarity. By using the SSE software module library, the Hurst index and the IR statistics of time series were estimated by applying analytic formulas, and the index of stability was estimated applying the robust method of regression of empirical quantiles. The efficiency of the analysis of the SSE module library was investigated by estimating the self-similarity indicators for realisation of the stabile processes while applying the method of computer-based modelling.

This paper summarizes research conducted on three computer-based video models’ effectiveness for learning based on memory and comprehension. In this quantitative study, a two-minute video presentation was created and played back in three different types of media players, for a sample of eighty-seven college freshman. The three players evaluated include a standard QuickTime video/audio player, a QuickTime player with embedded triggers that launched HTML-based study guide pages, and a Macromedia Flash-based video/audio player with a text field, with user activated links to the study guides as well as other interactive on-line resources. An assumption guiding this study was that the enhanced designs presenting different types of related information would reinforce the material and produce better comprehension and retention. However, findings indicate that the standard video player was the most effective overall, which suggests that media designs able to control the focus of a learner’s attention to one specific stream of information, a single-stream focused approach, may be the most effective way to present media-based content. Résumé: Cet article résume une étude vérifiant l’efficacité de l’apprentissage basé sur la mémorisation et la compréhension, conduite à partir de trois modèles basés sur la vidéo informatisée. Dans cette étude quantitative, une vidéo de deux minutes a été créée et lue sur trois types de lecteurs différents, pour un échantillon de 87 étudiants universitaires de première année. Les trois lecteurs évalués comprenaient un lecteur standard audio/vidéo Quicktime, un lecteur Quicktime avec déclencheurs intégrés qui lançait un guide d’étude en HTML, et un lecteur audio/vidéo Flash Macromedia avec un champ texte, comprenant des liens activés par l’usager vers des guides d’étude et d’autres ressources interactives en ligne. Une supposition guidant cette étude était que les designs enrichis présentant différents types d’informations interreliées renforceraient le matériel et produiraient une meilleure compréhension et une meilleure rétention. Cependant, les résultats indiquent que le lecteur vidéo standard était le plus efficace, ce qui suggère que les designs de médias concentrant l’attention de l’apprenant sur une source d’information spécifique seraient la meilleure façon de présenter du contenu médiatisé.
