Function-based design is the traditional approach in engineering design theory, proving useful and practical in many cases but showing limitations in others. Affordance-based design is an alternative approach that attempts to address some of function theory’s limitations by focusing attention on the interactions between systems. This paper compares function-based design with affordance-based design by examining their philosophies, tools, abilities, and suitability along a number of dimensions. We conclude that the approaches are compatible and suggest future work to realize their integration.

The current article suggests that alternatives to the current traditional learning methods are essentials if learning institutions are to provide people with effective life skills that enable them to be autonomous learners. This suggestion is based on a body of literature on alternative learning which stresses the need for fundamental change and hence, a paradigm shift in perception of learning in order to cope with the world-wide information explosion. The alternative non-traditional approach proposed in geodesic learning which stresses learning how to learn and self-directed inquiry as essential life skills which enable systems as well as the people in the systems to bring about their own transformation in response to changing situations and requirements. The current article discusses an alternative service delivery model, the geodesic information processing model, which falls within the realms of the geodesic philosophy. The implications of this alternative approach for the speech-language therapist are discussed.

Behavioural Management

The traditional approach to headache trigger management is to advise avoidance of all triggers, but we have advocated an alternative approach called ‘Learning to Cope with Triggers’ (LCT), in which the objective is to desensitise headache sufferers to some triggers or to build up tolerance for the triggers, using exposure techniques. A recent publication established the efficacy of this approach to trigger management. Reported here are three cases to illustrate how LCT is used in practice. Two cases were male and one was female, with ages ranging from 32 to 67 years. The headache diagnoses were frequent episodic tension-type headache, migraine without aura, and chronic tension-type headache; all had had headaches since childhood/adolescence. The headache triggers that were the focus of the intervention were heat, tiredness, and stress/anger. Post-treatment, changes in the capacity of the triggers to elicit headaches were reported in all three cases. Reductions in headaches from pre- to post-treatment, and from pre- to 4-month follow-up, were: case 1, 69% and 60% respectively; case 2, 76% and 80% respectively; and case 3, 73% and 61% respectively. Decreases in medication consumption, and enhanced self-efficacy were also recorded.

Abstract In this paper it is argued that methods are needed for the design of a larger variety of product aspects than is feasible with mechanical engineering design methodology of today. Design methods found within the European schools of design are inadequate for the design of products other than machine systems of transforming character. The reason for this is that the underlying theories only describe the nature of ‘operand-transforming’ technical systems, and that the description of the process and function systems are too narrowly defined to be useful for the design of ‘non-transforming’ products, or for products where the human is involved as an active user. The paper takes as the standpoint that the functional language, in accordance with established foundation in engineering design theory, is a successful means to treat usability aspects of human-product systems. An extended process modeling view based on product life-phase thinking including a ‘use-process’ is presented, focusing the attention towards the use, and not merely the workings, of the product. Also, extended definitions of a number of concepts are proposed, and function-classes of the human-product system, leading to a more generally applicable use of functions as a modeling tool when describing products, is introduced. The proposed functional language is illustrated in a product case example.

Scholarly Attention

To fight the risks caused by excessive self-disclosure especially regarding sensitive data such as genetic ones, it might be desirable to prevent certain disclosures. When doing so, regulators traditionally compel protection, for example by prohibiting the collection and/or use of genetic data even if citizens would like to share these data. This chapter provides an introduction into an alternative approach which has recently received increased scholarly attention: privacy protection by the use of nudges. Such nudges may in the future provide an alternative to compelled protection of genetic data or complement the traditional approach. This chapter first describes behavioral psychology's findings that citizens sometimes act irrational. This statement is consequently explained with the insights that these irrationalities are often predictable. Thus, a solution might be to correct them by the use of nudges.

This chapter discusses the development of a virtual laboratory (VL) named “EduPhysics,” an assistive software tailored around the Namibian Physical Science textbook for Grade 8 learners, and examines the viability of implementing VL in education. It further presented reviews on the role of computer simulations in science education and teachers' perspective on the use of EduPhysics in physical science classrooms. The chapter adopted a mixed method with an experimental research design and used questionnaires and interviews as data collection tools in high school physical science classes. The analysis found that there are limited resources in most physical science laboratories. Computer laboratories, however, are well equipped and have computing capacities to support the implementation of VL. It was concluded that virtual laboratories could be an alternative approach to hands-on practical work that is currently undertaken in resource-constrained physical science labs. For future work, augmented reality and logs will be incorporated within EduPhysics.

While design theories in visual displays have been well developed and further refined, relatively little research has been conducted on design theories and models in auditory displays. The existing discussions mainly account for functional mappings between sounds and referents, but these do not fully address design aspects of auditory displays. To bridge the gap, the present proposal focuses on design affordances in sound design among many design constructs. To this end, the definition and components of design affordances are briefly explored, followed by the auditory display examples of those components to gauge whether sound can deliver perceived affordances in interactive products. Finally, other design constructs, such as feedback and signifier, are discussed together with future work. This exploratory proposal is expected to contribute to elaborating sound design theory and practice.

Purpose – The purpose of this paper is to present a combined framework for system design using Six Sigma and Lean concepts. Systems Engineering has evolved independently and there are numerous tools and techniques available to address issues that may arise in the design of systems. In the context of systems design, the application of Six Sigma and Lean concepts results in a flexible and adaptable framework. A combined framework is presented here that allows better visualization of the system-level components and their interactions at parametric level, and it also illuminates gaps that make way for continuous improvement. The Deming’s Plan-Do-Check-Act is the basis of this framework. Three case studies are presented to evaluate the application of this framework in the context of Systems Engineering design. The paper concludes with a summary of advantages of using a combined framework, its limitations and scope for future work. Design/methodology/approach – Six Sigma, Lean and Systems Engineering approaches combined into a framework for collaborative product development. Findings – The present framework is not rigid and does not attempt to force fit any tools or concepts. The framework is generic and allows flexibility through a plug and play type of implementation. This is important, as engineering change needs vary constantly to meet consumer demands. Therefore, it is important to engrain flexibility in the development of a foundational framework for design-encapsulating improvements and innovation. From a sustainability perspective, it is important to develop techniques that drive rationality in the decisions, especially during tradeoffs and conflicts. Research limitations/implications – Scalability of the approach for large systems where complex interactions exist. Besides, the application of negotiation techniques for more than three persons poses a challenge from a mathematical context. Future research should address these in the context of systems design using Six Sigma and Lean techniques. Practical implications – This paper provides a flexible framework for combining the three techniques based on Six Sigma, Lean and Systems Engineering. Social implications – This paper will influence the construction of agent-based systems, particularly the ones using the Habermas’s theory of social action as the basis for product development. Originality/value – This paper has not been published in any other journal or conference.

Design Experience

Historically, the teaching of design theory in an engineering curriculum was relegated to a senior capstone design experience. Presently, however, engineering design concepts and courses can be found through the entirety of most engineering programs. Educators have recognized that engineering design provides a foundational platform that can be used to develop educational strategies for a wide array of engineering science principles. More recently, educators have found that product archaeology provides an effective platform to develop scalable learning materials, strategies, and educational innovations across these design courses. In this paper, we focus on the upper level design experience and present a set of innovative strategies aimed at teaching design in a global perspective. Moreover, this approach facilitates meeting the challenging requirements of ABET’s Outcome h. The effectiveness of the strategies is assessed using a benchmark national survey on the Engineer of 2020. Results demonstrate a significant increase in student perception across a number of skill and knowledge areas, which are critical to the next generation of engineers.
