摘要： Building upon years of evolution in object-oriented programming language design, Java has emerged as the language of choice among many educators for teaching introductory computer science. A clean, type-safe language, Java provides a garbage collected heap and a comprehensive exception-handling mechanism. However, in spite of this support, many students in introductory computer science courses still find programming to be an overwhelming source of frustration. Linguistic concerns and programming mechanics demand so much attention that deeper concepts are often postponed for later courses, leaving students in introductory courses with the mistaken impression that computer science is a shallow discipline, concerned only with transcribing ideas into code, and not with the ideas themselves. JPie is a tightly integrated programming environment for live software construction in Java. JPie treats programming as an application in its own right, providing a visual representation of class definitions and supporting direct manipulation of graphical representations of programming abstractions and constructs. Exploiting Java's reflection mechanism, JPie supports the notion of a dynamic class that can be modified while the program is running, thereby eliminating the edit-compile-test cycle. Following years of experience using Java as the vehicle for teaching introductory computer science, we have designed JPie to provide a more natural and fluid software development process that both raises the level of abstraction and eliminates many of the common pitfalls that beginning Java programmers face. This paper studies JPie from an educational perspective. We systematically review key programming abstractions and explain how JPie supports them in ways that keep beginning programmers focused on important ideas. Our experience using JPie in an introductory computer science survey course for non-majors is briefly discussed. (C) 2004 Elsevier B.V. All rights reserved.

关键词： GENE expression   DATABASES   RESEARCH   DNA microarrays   GENES   TECHNOLOGY  

摘要： Microarrays allow monitoring of gene expression for tens of thousands of genes in parallel and are being used routinely to generate huge amounts of valuable data. Handling and analysis of such data are becoming major bottlenecks in the utilization of the technology. To enable the researcher to interpret the results postanalysis, we have developed a laboratory information management system for microarrays (LIMaS) with an n-tier Java front-end and relational database to record and manage large-scale expression data preanalysis. This system enables the laboratory to replace the paper trail with an efficient and fully customizable interface giving it the ability to adapt to any working practice, e.g., handling many resources used to form many products (chaining of resources). The ability to define sets of activities, resources, and workflows makes LIMaS MIAME-supportive.
