There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

NUDGE: IMPROVING DECISIONS ABOUT HEALTH, WEALTH, AND HAPPINESS by Richard H. Thaler and Cass R. Sunstein Penguin Books, 2009, 312 pp, ISBN 978-0-14-311526-7This book is best described formally as a general explanation of and advocacy for libertarian paternalism, a term coined by the authors in earlier publications. Informally, it is about how leaders, systems, organizations, and governments can nudge people to do the things the nudgers want and need done for the betterment of the nudgees, or of society. It is paternalism in the sense that "it is legitimate for choice architects to try to influence people's behavior in order to make their lives longer, healthier, and better", (p. 5) It is libertarian in that "people should be free to do what they like - and to opt out of undesirable arrangements if they want to do so", (p. 5) The built-in possibility of opting out or making a different choice preserves freedom of choice even though people's behavior has been influenced by the nature of the presentation of the information or by the structure of the decisionmaking system. I had never heard of libertarian paternalism before reading this book, and I now find it fascinating.Written for a general audience, this book contains mostly social and behavioral science theory and models, but there is considerable discussion of structure and process that has roots in mathematical and quantitative modeling. One of the main applications of this social system is economic choice in investing, selecting and purchasing products and services, systems of taxes, banking (mortgages, borrowing, savings), and retirement systems. Other quantitative social choice systems discussed include environmental effects, health care plans, gambling, and organ donations. Softer issues that are also subject to a nudge-based approach are marriage, education, eating, drinking, smoking, influence, spread of information, and politics. There is something in this book for everyone.The basis for this libertarian paternalism concept is in the social theory called "science of choice", the study of the design and implementation of influence systems on various kinds of people. The terms Econs and Humans, are used to refer to people with either considerable or little rational decision-making talent, respectively. The various libertarian paternalism concepts and systems presented are tested and compared in light of these two types of people. Two foundational issues that this book has in common with another book, Network of Echoes: Imitation, Innovation and Invisible Leaders, that was also reviewed for this issue of the Journal are that 1 ) there are two modes of thinking (or components of the brain) - an automatic (intuitive) process and a reflective (rational) process and 2) the need for conformity and the desire for imitation are powerful forces in human behavior. …

Purpose – Customer experience has become increasingly important for service organizations that see it as a source of sustainable competitive advantage, and for service designers, who consider it fundamental to any service design project.Design/methodology/approach – Integrating contributions from different fields, CEM was conceptually developed to represent the different aspects of customer experience in a holistic diagrammatic representation. CEM was further developed with an application to a multimedia service. To further develop and build CEM's models, 17 customers of a multimedia service provider were interviewed and the data were analyzed using Grounded Theory methodology.Findings – Combining multidisciplinary contributions to represent customer experience elements enables the systematization of its complex information. The application to a multimedia service highlights how CEM can facilitate the work of multidisciplinary design teams by providing more insightful inputs to service design.Originality/...

The widespread popularity of Pokemon GO presents the first opportunity to observe the geographic effects of location-based gaming at scale. This paper reports the results of a mixed methods study of the geography of Pokemon GO that includes a five-country field survey of 375 Pokemon GO players and a large scale geostatistical analysis of game elements. Focusing on the key geographic themes of places and movement, we find that the design of Pokemon GO reinforces existing geographically-linked biases (e.g. the game advantages urban areas and neighborhoods with smaller minority populations), that Pokemon GO may have instigated a relatively rare large-scale shift in global human mobility patterns, and that Pokemon GO has geographically-linked safety risks, but not those typically emphasized by the media. Our results point to geographic design implications for future systems in this space such as a means through which the geographic biases present in Pokemon GO may be counteracted.

The Geography of Pokémon GO: Beneficial and Problematic Effects on Places and Movement

Non‐intrusive load monitoring (also known as NILM or energy disaggregation) is the process of estimating the energy consumption of individual appliances from electric power measurements taken at a limited number of locations in the electric distribution of a building. This approach reduces sensing infrastructure costs by relying on machine learning techniques to monitor electric loads. However, the ability to evaluate and benchmark the proposed approaches across different datasets is key for enabling the generalization of research findings and consequently contributes to the large‐scale adoption of this technology. Still, only recently researchers have focused on creating and standardizing the existing datasets in order to deliver a single interface to run NILM evaluations. Furthermore, there is still no consensus regarding, which performance metrics should be used to measure and report the performance of NILM systems and their underlying algorithms. This paper provides a review of the main datasets, metrics, and tools for evaluating the performance of NILM systems and technologies. Specifically, we review three main topics: (a) publicly available datasets, (b) performance metrics, and (c) frameworks and toolkits. The review suggests future research directions in NILM systems and technologies, including cross‐datasets, performance metrics for evaluation and generalizable frameworks for benchmarking NILM technology.

ion Presentation Control PAC Aplication Conceptual Interface (ACI) Instantiation of a User Interface System Functional core Output Input User User Functional core Figure II.23 Conceptual Architectural Models for User-interface Objects In the late 1980s and early 1990s several approaches of implementation architectural models for interactive systems emerged. Unlike conceptual models, implementation models organize the interactive system as a set of software components and aim at practical software engineering considerations like reusability, maintainability, and performance. The Seeheim model [Bass, 1992] proposes a simple three-layer model (application, dialogue and presentation) of an interactive system, roughly coupling the semantic, syntactic and lexical functionality’s of the user interface. The application component models the domain-specific components, the dialogue component defines the structure of the dialogue between the user and the application and, finally, the presentation component is responsible for the external to internal mapping of basic symbols. The Seeheim model is considered a correct and useful model for specification of interactive systems [Duce et al., 1991]. However, its support for distribution, concurrency, resource management and performance is recognized to be insufficient. Background: A Brief Survey of Usability Engineering and Object Modeling 58 The Arch model [Pfaff and Haguen, 1985] is a revision of the Seeheim model aimed at providing a framework for understanding of the engineering tradeoffs, specifically, in what concerns evaluating candidate run-time architectures. The Arch model proposes a five-layer approach balanced around the dialogue component. The components of the Arch model are: • The interaction toolkit component implements the physical interaction with the end-user; • The presentation component provides a set of toolkit independent objects; • The dialogue component is responsible for task-level sequencing, providing multiple view consistency, and mapping the between domain specific and user interface specific formalisms; • The domain adapter component implements domain related tasks required but not available in the domain specific component; • The domain specific component controls, manipulates and retrieves domain data and performs other domain related functions.
