The proceedings contain 17 papers. The special focus in this conference is on Informatics and Psychology. The topics include: Nice drawings of graphs are computationally hard;beyond the desk top metaphor: Information retrieval with an icon-based interface;visualization and direct manipulation in user interfaces: Are we overdoing it?;teaching a spreadsheet application - Visual-spatial metaphors in relation to spatial ability, and the effect on mental models;some HCI issues concerned with displaying quantitative information graphically;implementing direct manipulation query languages using an adequate data model;modelling the relationship between state and display in interactive systems;a software engineering environment for developing human-computer interfaces;intrinsic geometry in LOGO- distance of linear segments;beyond visualization: Knowing and understanding;generating pictorial presentations for advice-giving dialog systems;what does knowledge look like?: Presenting knowledge structures in a ZOO of objects;representing semantic knowledge with 2-dimensional rules in the domain of functional programming;a graphical representation of the Prolog programmer’s knowledge;fAST - A stepper in an object-orientedprogramming environment;integrating visual aids into an objectorientedprogramming environment;a context-oriented approach for decision support.

The proceedings contain 45 papers. The topics discussed include: playground: an objectoriented simulation system with agent rules for children of all ages;neuralagents - a frame of mind;incremental distribution of timestamp packets: new approach to distributed garbage collection;extending the operating system to support an object-oriented environment;an efficient implementation of SELF, a dynamically-typed object-oriented language based on prototypes;object-oriented design: a responsibility-driven approach;PROCOL a parallel object language with protocols;an extended frame language;inheritance and synchronization with enabled-sets;good news, bad news: experience building a software development environment using the object-oriented paradigm;design of the opportunistic garbage collector;problem-solution mapping in object-oriented design;saving a legacy with objects;contributions to teaching object-oriented design and programming;strategies for scientific prototyping in Smalltalk;mandatory security in object-oriented database systems;DSM : an object-relationship modeling language;Vamp: the Aldus application framework;and a fast method dispatcher for compiled languagues with multiple inheritance.
Many numerical analysts and Lisp/Smalltalk programmers share the assumption that languages like Fortran are more appropriate for traditional, quantitative scientific programming than object-orientedlanguages. To show...

This paper uses the persistent object system PCLOS to survey some problems and benefits of object persistence. The system is analyzed along several relevant dimensions. PCLOS provides object persistence for an object-...

This paper develops a system of explicit interfaces for object-orientedprogramming. The system provides the benefits of module interfaces found in languages like Ada and Modula-2 while preserving the expressiveness t...

It is difficult to introduce both novice and experienced procedural programmers to the anthropomorphic perspective necessary for object-oriented design. We introduce CRC cards, which characterize objects by class name...

A multilevel secure object-oriented data model (using the ORION data model) is proposed for which mandatory security issues in the context of a database system is discussed. In particular the following issues are deal...

Many tools and techniques exist for the modeling and analysis of computer and communication systems. These tools are often complex and tailored to a narrow range of problems. The system analysis task often requires co...

This paper discusses the introduction of explicit metaclasses à la ObjVlisp into the Smalltalk-80 language. The rigidity of Smalltalk metaclass architecture motivated this work. We decided to implement the ObjVli...
