Functional tones is a concept that originates in theoretical biology and resembles how the concept ‘affordances’ is used. Both functional tones and affordances are concepts dealing with particularly salient features in an individual’s immediate environment. The concept of affordances has proven useful for practitioners of usability and design as it supports intuitive ways of classifying how action possibilities match between a person and an object [1]. Functional tones have, however, thus far remained obscure among practitioners, despite functional tones having a stronger theoretical foundation and facilitates a deeper and more human-centred analysis of interaction. The functional tones related to an object depend not only on the modes of sensation and action the perceiver is capable of, but also more subjective aspects such as experience, motivation and emotions. Using functional tones in design or analysis of interaction provides a fundamentally user experience centred perspective while avoiding the philosophical luggage of affordances.

Objective: To highlight the importance of the personal experience of users who interact with technology in safety-critical domains and summarize three interaction concepts and the associated theories that provide the means for addressing user experience. Background: In health care, the dominant concepts of interaction are based on theories arising from classic cognitive psychology. These concepts focus mainly on safety and efficiency, with too little consideration being given to user experience. Method: Users in complex socio-technical and safety-critical domains such as health care interact with many technological devices. Enhancing the user experience could improve the design of technology, enhance the well-being of staff, and contribute to modern safety management. We summarize concepts of “interaction” based on modern theories of human–computer interaction, which include the personal experience of users as an important construct. Results and Conclusion: Activity theory, embodiment, and interaction as experience provide a theoretical foundation for considering user experience in safety-critical domains. Using an example from anesthesiology, we demonstrate how each theory provides a unique but complementary view on experience. Finally, the methodological possibilities for considering personal experience in design and evaluations vary among the theories. Application: Considering user experience in health care and potentially other safety-critical domains can provide an additional means of optimizing interaction with technology, contributing to the well-being of staff, and improving safety.

Do So

There is renewed interest in the need to focus on corporate governance in an environment where it is a performance imperative for all small and large organizations, private and public, beginner or established.The purpose of this study is to demonstrate the place of corporate governance practices in organizations to ensure that the board, officers, and directors take action to protect shareholder interests and all stakeholders. It is important to focus on the effect of these practices on improving performance and competitiveness. To do so, we opted for the hypothetico-deductive method with a quantitative approach. Our theoretical foundation is theory is agency theory.

AbstractThis paper first briefly reviews a few of the early studies that established some of the salient features of light-induced degradation in a-Si,Ge:H. In particular, I discuss the fact that both Si and Ge metastable dangling bonds are involved. I then review some of the recent studies carried out by members of my laboratory concerning the details of degradation in the low Ge fraction alloys utilizing the modulated photocurrent method to monitor the individual changes in the Si and Ge deep defects. By relating the metastable creation and annealing behavior of these two types of defects, new insights into the fundamental properties of metastable defects have been obtained for amorphous silicon materials in general. I will conclude with a brief discussion of the microscopic mechanisms that may be responsible.
