Embedded software development involves many knowledge acquisition (KA) tasks that collectively account for a significant proportion of development costs. This paper presents a pilot study that used case studies to investigate the extent to which knowledge acquired in learning tasks was used in developing a final product. Data obtained from the case studies were used to construct event chains, which trace the amount of time spent on KA tasks and the types of knowledge acquired in individual learning tasks. Knowledge acquired was separated into three categories: knowledge of data, knowledge of process, and knowledge of innovation. Each top-level category was further partitioned into productive and nonproductive knowledge depending on whether the knowledge was, or was not used, in the construction of the final product. The event chains were processed to visualize the chronological progression of how knowledge acquired in the separate categories moved between subcategories of productive and nonproductive knowledge as development progressed. Results of this analysis show trends in KA for the case studies investigated, which we plan to use in the design of future work on this topic.

Model Based Testing

This chapter reports the results of a cycle computer case study and a previously conducted industrial case study from the automation domain. The key result is a model-based testing process for highly configurable embedded systems. The initial version of the testing process was built upon parameterizeable systems. The cycle computer case study adds the configuration using the product line concept and a feature model to store the parameterizable data. Thus, parameters and their constraints can be managed in a very structured way. Escalating demand for flexibility has made modern embedded software systems highly adjustable. This configurability is often realized through parameters and a highly configurable system possesses a handful of those. Small changes in parameter values can often account for significant changes in the system's behavior, whereas in some other cases, changed parameters may not result in any perceivable reaction. The case studies address the challenge of applying model-based testing to configurable embedded software systems in order to reduce development effort. As a result of the case studies, a model-based testing process was developed. This process integrates existing model-based testing methods and tools such as combinatorial design and constraint processing as well as the product line engineering approach. The testing process was applied as part of the case studies and analyzed in terms of its actual saving potentials, which turned out to reduce the testing effort by more than a third.

ABSTRACTThis paper addresses the issue of corporate sustainability. It examines why achieving sustainability is becoming an increasingly vital issue for society and organisations, defines sustainability and then outlines a set of phases through which organisations can move to achieve increasing levels of sustainability. Case studies are presented of organisations at various phases indicating the benefits, for the organisation and its stakeholders, which can be made at each phase. Finally the paper argues that there is a marked contrast between the two competing philosophies of neo-conservatism (economic rationalism) and the emerging philosophy of sustainability. Management schools have been strongly influenced by economic rationalism, which underpins the traditional orthodoxies presented in such schools. Sustainability represents an urgent challenge for management schools to rethink these traditional orthodoxies and give sustainability a central place in the curriculum.

Multiple Regression Technique

Short-form versions of the Screening Test of Spanish Grammar (Toronto, 1973) and the Northwestern Syntax Screening Test (Lee, 1971) were devised for use with bilingual Latino children while preserving the original normative data. Application of a multiple regression technique to data collected on 60 lower social status Latino children (four years and six months to seven years and one month) from Spanish Harlem and Yonkers, New York, yielded a small but powerful set of predictor items from the Spanish and English tests. Clinicians may make rapid and accurate predictions of STSG or NSST total screening scores from administration of substantially shortened versions of the instruments. Case studies of Latino children from Chicago and Miami serve to cross-validate the procedure outside the New York metropolitan area.

Case Studies for Telepractice in AAC

Communication Needs

As the field of telepractice grows, perceived barriers to service delivery must be anticipated and addressed in order to provide appropriate service delivery to individuals who will benefit from this model. When applying telepractice to the field of AAC, additional barriers are encountered when clients with complex communication needs are unable to speak, often present with severe quadriplegia and are unable to position themselves or access the computer independently, and/or may have cognitive impairments and limited computer experience. Some access methods, such as eye gaze, can also present technological challenges in the telepractice environment. These barriers can be overcome, and telepractice is not only practical and effective, but often a preferred means of service delivery for persons with complex communication needs.
