Abstract. In Coupled Groundwater and Surface-Water Flow (GSFLOW) model, the three-dimensional finite-difference groundwater model (MODFLOW) plays a critical role of groundwater flow simulation, together with which the Precipitation-Runoff Modeling System (PRMS) simulates the surface hydrologic processes. While the model development of each individual PRMS and MODFLOW model requires tremendous time and efforts, further integration development of these two models exerts additional concerns and issues due to different simulation realm, data communication, and computation algorithms. To address these concerns and issues in GSFLOW, the present paper proposes a conceptual framework from perspectives of: Model Conceptualization, Data Linkages and Transference, Model Calibration, and Sensitivity Analysis. As a demonstration, a MODFLOW groundwater flow system was developed and coupled with the PRMS model in the Lehman Creek watershed, eastern Nevada, resulting in a smooth and efficient integration as the hydrogeologic features were well captured and represented. The proposed conceptual integration framework with techniques and concerns identified substantially improves GSFLOW model development efficiency and help better model result interpretations. This may also find applications in other integrated hydrologic modelings.

PurposeThe purpose of this paper is to explore innovations in customer experience at the intersection of the digital, physical and social realms. It explicitly considers experiences involving new technology-enabled services, such as digital twins and automated social presence (i.e. virtual assistants and service robots).Design/methodology/approachFuture customer experiences are conceptualized within a three-dimensional space – low to high digital density, low to high physical complexity and low to high social presence – yielding eight octants.FindingsThe conceptual framework identifies eight “dualities,” or specific challenges connected with integrating digital, physical and social realms that challenge organizations to create superior customer experiences in both business-to-business and business-to-consumer markets. The eight dualities are opposing strategic options that organizations must reconcile when co-creating customer experiences under different conditions.Research limitations/implicationsA review of theory demonstrates that little research has been conducted at the intersection of the digital, physical and social realms. Most studies focus on one realm, with occasional reference to another. This paper suggests an agenda for future research and gives examples of fruitful ways to study connections among the three realms rather than in a single realm.Practical implicationsThis paper provides guidance for managers in designing and managing customer experiences that the authors believe will need to be addressed by the year 2050.Social implicationsThis paper discusses important societal issues, such as individual and societal needs for privacy, security and transparency. It sets out potential avenues for service innovation in these areas.Originality/valueThe conceptual framework integrates knowledge about customer experiences in digital, physical and social realms in a new way, with insights for future service research, managers and public policy makers.

Chapter 3 describes the anatomy of medical uncertainty, identifying key attributes that give it a three-dimensional conceptual shape, form, and structure. It characterizes uncertainty in terms of its (1) fundamental sources (root causes), (2) issues (substantive problems), and (3) loci (persons in whose minds uncertainty resides) and presents a conceptual framework that allows the variety of uncertainties in medicine to be classified and better understood. The chapter makes the case that in all of these ways, a three-dimensional conceptual framework can facilitate a more intentional, targeted, and rational approach to evaluating medical uncertainty. By providing a way of visualizing, ordering, and objectifying an otherwise invisible, disordered, subjective reality, the framework can ultimately enable clinicians and patients to better manage medical uncertainty.

Problem-based learning is an instructional strategy that emphasises the accumulation and development of knowledge via an active and experiential based approach to solving problems. This pedagogical framework can be instantiated using gaming technology to provide learners with the ability to control their learning experience within a dynamic, responsive, and visually rich three-dimensional virtual environment. In this regard, a conceptual framework referred to as the Simulation, User, and Problem-based Learning (SUPL) approach has been developed in order to inform the design of 3D simulation environments based on gaming technology within a problem-based learning pedagogy. The SUPL approach identifies a series of design factors relative to the user, the problem-solving task, and the 3D simulation environment that guide the learning process and facilitate the transfer of knowledge. This paper will present a simulation environment design according to this conceptual framework for a problem-solving task within the context of an underground mine emergency evacuation. The problem-solving task will be designed to satisfy learning objectives that relate to the development of knowledge and skills for emergency evacuation of the Dominion Mining’s Challenger mining operation located in South Australia.

Colour Coding

Centre – surround stimuli evoke colour appearances (resembling surface colours) which cannot be produced by a single homogeneous spot of light alone (eg brown or grey). Although this seems of great impact to a general theory of colour (including ‘colour constancy’), the psychophysics of these ‘minimal relational stimuli’ is still less well understood than often assumed. On the basis of empirical as well as theoretical observations concerning centre– surround-type stimuli we introduce a relational model of colour coding. At the core of this model is the concept of a three-dimensional linear incremental colour code which behaves differently for increments and decrements. This model takes into account results on ‘discounting the background’ mechanisms and it is closely related to ratio-based relational concepts and to certain opponent-colour theories. In addition, it provides an analogue to the classical distinction between light and object colours, and covers colour appearances related to object colours as well. Within the conceptual framework offered, problems of complex colour perception (eg ‘colour constancy’) and judgmental modes are discussed. Conclusions regarding general limitations of three-dimensional modelling in colour perception are derived and corresponding refinements of the relational perspective are briefly outlined.

The pumping attributes of the heart remain active topics of investigation and mastery of how the heart functions as a pump is part of the fund of knowledge of physiologists and cardiologists. The advent of high-resolution, real-time imaging (computed tomography, magnetic resonance imaging cardiac catheterization, two- and three-dimensional echocardiography) has continued to advance our understanding of how the four-chambered heart (left heart, right heart) works as it fills and as it empties. The insights that have evolved emanate from a conceptual framework based on motion (kinematics) of selected phases and portions of the four-chambered heart and the contents of the pericardial sac. Concepts include pressure pumping, volume pumping, constant-volume pumping, the relationship between atrial and ventricular function and atrial and ventricular indexes, the role of the heart as a suction pump, laws that govern isovolumic relaxation, and the relationship of intraventricular fluid mechanics to diastolic function and wall motion. Accordingly, by asking such questions as ‘What is the ejection fraction of the pericardial sack, and why does it have the numerical value it has?’ or ‘Why does the left atrium fill in two phases—one in systole and one in diastole?’ or ‘How is atrial conduit volume related to diastolic wall motion?’ one can gain new insights into pumping function. This chapter presents a simple, useful, yet powerful conceptual framework that can be used descriptively or mathematically to addresses these and other clinically important themes.

AbstractThis paper presents an investigation into patterns of interaction in synchronous, text-based computer-mediated communication (SCMC) with a focus on participation. The data constitute a corpus of 3,785 words from a series of interactions between student teachers performing learning activities in a three-dimensional online environment. Drawing on a systemic functional grammar perspective of language, we aim to develop a conceptual framework for understanding participation as made up of interactional patterns in students’ linguistic exchanges while performing learning activities. Our findings show that verbal negotiation that creates a shared understanding of what the group should accomplish or a common view of how to perform the activity is more frequent than strict activity organization. We argue that there are features of CMC signaling higher levels of complexity than those ordinarily found in face to face or written communication. The three broad interactional features identified – blending, turn-taking collaboration and delay endurance – corroborate our claim. This paper presents evidence that participation in text-based SCMC with learning purposes demands a disposition for collaboration and solidarity, a capacity to endure delay, and the ability to manage a conglomerate of information and communication tools without instructions on how-to processes.
