计算机软件的著作权保护——计算机软件的保护范围

<正> 有关计算机软件保护,根据构思/表现二分法原则,主要受著作权及专利权的保护。著作权与专利权是从两个不同的侧面对计算机软件进行保护,专利保护在一定程度上弥补了著作权保护的不足,但实际上软件却难以得到专利权的有效保护。因此,计算机软件著作权保护已成为有关软件法律保护的最主要方式。 我们知道著作权保护构思的表现,而不保护构思本身。由于计算机软件本身也属于著作物的一种。因此,如何确定计算机软件的保护范围

Transportable package software

Package programs allow people who are not computer experts to use the power of machine computation for specialized purposes. Because the designers of scientific packages are more often experts in their scientific field than in computing, they may ignore issues of transportability and ease-of-use until too late, and produce a package that is difficult to use, and difficult to move to a different computer. In this paper we suggest some techniques to aid the scientific package designer. We suggest a kernel of routines that interface to the peculiar operating system of each machine, providing sophisticated but standard operating system services. This kernel makes the operating system of each computer appear identical and does not pose a difficult implementation problem. Above this interface all code can be machine-independent, without sacrificing power and ease of use on any machine. We also suggest some novel organizations of processing routines designed to make the system easy to alter and extend. Complete independence of modules encourages centralization of tasks, which is both efficient and essential for easy extension. With this organization, the vast preponderance of package code can be written in machine-independent ANSI FORTRAN. We suggest the use of a preprocessor like RATFOR to make this more pleasant. The paper closes with an application to an image-processing package, in which a major problem is the flexible sequencing of processing routines.

The role of errors in learning computer software

Little research has been done examining the role of errors in learning computer software. It is argued, though, that understanding the errors that people make while learning new software is important to improving instruction. The purpose of the current study was to (a) develop a meaningful and practical system for classifying computer software errors, (b) determine the relative effect of specific error types on learning, and (c) examine the impact of computer ability on error behaviour. Thirty-six adults (18 males, 18 females), representing three computer ability levels (beginner, intermediate, and advanced), volunteered to think out loud while they learned the rudimentary steps (moving the cursor, using a menu, entering data) required to use a spreadsheet software package. Classifying errors according to six basic categories (action, orientation, knowledge processing, seeking information, state, and style) proved to be useful. Errors related to knowledge processing, seeking information, and actions were observed most frequently, however, state, style, and orientation errors had the largest immediate negative impact on learning. A more detailed analysis revealed that subjects were most vulnerable when observing, trying to remember, and building mental models. The effect of errors was partially related to computer ability, however beginner, intermediate and advanced users were remarkably similar with respect to the prevalence of errors.     

Development of a software package for ergonomic assessment of manufacturing industry

A computer software package has been developed to be used as a self-assessment tool to evaluate ergonomic improvement potential of production systems by engineers, managers and safety professionals. Production managers of manufacturing industries with no prior knowledge of ergonomics were able to identify ergonomic deficiencies successfully (81%) in the shop floors as a result of the application of the ergonomic assessment tool. This enabled them to formulate intervention strategies to improve ergonomic conditions in their industries. The software package is user friendly, self-explanatory and provides relevant information, data and guidelines. It is unique, as the users will have access to necessary ergonomics information, which is often lacking in the manufacturing industries, especially in developing countries.     

The influencing causes of software unavailability: A case study from industry

Software unavailability can lead to disastrous consequences ranging from delays and cancellation to a loss of millions of dollars of technology. However, research on the causes that can make systems unavailable is still little. The aim of this paper is to investigate such causes in an industrial context using 2 qualitative approaches ((a) interview and (b) retrospective analysis) using archival data and records from a student information system. As a result, connectivity, human, hardware, storage, and software were found to be the important categories of causes for the unavailability. Besides, the critical lessons to be learned that relate to activities of software management and software business are also discussed. This includes vendor support, systems documentation, health check process, licensing, and software updating or upgrading. To strengthen the claim that our findings are promising, we compare our main findings with those of a previous study. This study can generally assist software engineering people including engineers, developers, project managers, vendors. Additionally, this paper dis cusses the threats to the study's validity and suggests open problems for future research.
