The current report presents the development and application of a novel methodological approach for computer-based methods of processing and analysis of proliferative tissues labeled by ABC-peroxidase method using 3, 3′-diaminobenzidine (DAB) as chromogen. This semiautomatic method is proposed to replace the classical manual approach, widely accepted as gold standard. Our method is based on a visual analysis of the microscopy image features from which a computational model is built to generate synthetic images which are used to evaluate and validate the methods of image processing and analysis. The evaluation allows knowing whether the computational methods applied are affected by the change of the image characteristics. Validation allows determining the method’s reliability and analyzing the concordance between the proposed method and a gold standard one. Additional strongness of this new approach is that it may be a framework adaptable to other studies made on any kind of microscopy.

Abstract Computer based growth projection systems can help foresters evaluate the effect of management prescriptions. However, using projection systems wisely requires information about how accurate they are. Both parts of accuracy, bias and precision, are estimated for volume predictions from a Lake States projection system using data from 822 remeasured plots. Volume tends to be underpredicted for four locations in the northern part of the Lake States but overpredicted for one location in Lower Michigan. The bias is large for dense stands and for northern hardwood and lowland hardwood stands in Lower Michigan. Forests are highly variable, however, and the precision of a projection system must be estimated as well as its bias. Prediction intervals are computed that help estimate the likely range for a given prediction. The interval that has a 90% probability of containing the true volume can be quite large. North. J. Appl. For. 6:109-114, September 1989.

A new computer-based approach to teaching thermodynamics is being developed and tried by two mechanical engineering professors at the U.S. Naval Academy. The course uses sophisticated software, in this case CyclePad, to work all of the homework problems. A new text, written with traditional theory but computer-based problems, accommodates the new approach. The new course is scheduled for Fall Term 2001 at the Naval Academy. Computer-based thermodynamics courses teach the same theory as traditional thermodynamics courses as well as the same types of problems. However, traditional thermodynamic cycle hand calculations are replaced by cycle calculations using CyclePad. This new example of Intelligent Computer-Assisted Instruction, ICAI, switches emphasis from learning cycle calculations to learning cause and effect through parametric analysis. Parametric analysis is made feasible through experimentation using computer models. For this, CyclePad has artificial intelligence, sensitivity analysis and graphical presentation capabilities. Traditionally, thermodynamics culminates in analysis of the thermodynamic cycles. In this course, students will progress well beyond traditional thermodynamics courses by emphasizing cycle analysis.

This article investigates how, and with what success, global organisations design computer-based systems for knowledge sharing which aim to balance centralised and standardised approaches against more diverse local needs. The empirical basis for the article is provided by an analysis of two different global organisations, each with its own knowledge-sharing infrastructure in place. We use third-generation activity theory as the theoretical basis for our analysis. The contributions from this article are twofold. The first is our theoretical lens, where activity theory is applied to the domain of global information systems and their organisational context. This analysis provides a new approach in addressing both the mediation of and motivations behind knowledge-sharing activity. The second contribution concerns the theoretical and practical insights this gives on the problems and challenges of achieving a balance between global and local priorities within highly distributed work contexts, and the role of computer-based systems in this arena.

AbstractThis applied experimental research tested the effectiveness of a universal, student-focused intervention (‘Memory Mates’), specifically focused on supporting students to use attention and working memory strategies within academic contexts, unlike computer-based programs. Memory Mates is presented in the form of icons and explanations, with the strategies embedded within the classroom. Analyses compared the impact of the intervention over 8 months in three schools with three control schools, comprising 13 Year 4 primary school classes. The intervention group students showed a significant improvement in mathematics and spelling; however, there was no differential effect on reading comprehension or academic engagement. Based on the present results, it is contended that implementing Memory Mates within classroom contexts demonstrated promising potential as a new approach to supporting academic progress.
