Agile Process

Systems change often, and each change requires reverification and revalidation. Modern software development processes such as agile process even welcome and accommodate frequent software changes. Traditionally, software reverification and revalidation are handled by regression testing. This chapter presents a pattern-oriented scenario-based approach to rapidly reverify and revalidate frequently changed software. Key features of this approach are (1) classifying system scenarios into reusable patterns; (2) application of a formal completeness analysis to identify missing scenarios; (3) identifying scenario patterns (SPs) and corresponding verification patterns (VPs) and robustness patterns (RBPs); (4) rapid test script generation by reusing test script templates. This approach is also compatible with formal approaches such as model checking. This approach has been used at industrial sites to test safety-critical medical devices with significant savings in cost and effort. The chapter presents several examples to illustrate the effectiveness and efficiency of this approach.

Open Source Development

This chapter discusses the impact that open source software has on our perception and use of intellectual property. The theoretical foundation of the paper is constructionist in that it holds intellectual property to be a social construction that is created and legitimized by narratives. In a first step, the chapter recounts the narratives that are usually found in the literature to justify the creation and protection of intellectual property. The two most important streams of narratives are the utilitarian and the natural rights arguments. In a second step, the paper proceeds to the impact that the use of information and communication technology (ICT) has on the narratives of intellectual property. From there, the chapter progresses to a discussion of the impact of open source software on these narratives. It will be argued that open source software changes our perception of intellectual property because it offers evidence that some of the classical narratives are simplistic. At the same time it will become clear that open source is not a frontal assault on intellectual property because it is partly based on ownership of intellectual artefacts. The conclusion discusses how this change of narratives caused by open source software may reflect on our institutions, laws, and regulations of intellectual property.

Software Changes

Software projects keep changing all the time. Understanding the nature of the changes can help build higher quality projects. In this paper, the authors studied software changes on a new entity, statement. They found some types of statements are more likely to change than others. Furthermore, the authors studied software changes to fix bugs and also found some types of statements are more likely to change than others to fix bugs. These statements are more likely to cause bugs, which should be paid more attention to.

Abstract Alpine skiing is one of the most popular leisure time winter sporting activities. Skiing imposes high requirements concerning physical fitness, particularly regarding balance abilities. The main objective of this study was to evaluate the changes in balance performance of recreational skiers after a seven-day ski camp. A total of 78 students - 24 women and 54 men - participated in the study. The ski course was held in accordance with the official program of the Polish Ski Federation. The study sample was comprised of 43 beginners and 35 intermediate skiers. All students were tested with the MFT S3-Check, the day before and the day after the ski camp. The test system consisted of an unstable uniaxial platform, with an integrated sensor and corresponding software. Changes in balance performance (sensory and stability index) were evaluated using paired t-tests. Additionally, changes in sensory and stability categories, which were based on the norm data, were analyzed. Female and male participants showed significantly better sensory and stability indices after skiing. Considerable changes from weak or very weak to average or good balance categories could be seen after skiing for both sexes. Regarding skiing experience, both beginners and intermediate skiers improved their sensory and stability indices significantly after skiing. Hence, recreational alpine skiing resulted in better balance performance regardless of sex or skiing experience. Skiing as an outdoor activity offers the opportunity to improve balance performance with a positive impact on everyday life activities.
