Service design builds upon contributions from multiple fields, including management, information technology, and interaction d...

Health information systems are becoming ubiquitous throughout healthcare delivery processes. Governments, enticed by the potential for improved patient care and cost reduction, are pushing for more integrated IT systems in healthcare. However, the successful adoption of these systems depends on the value they create as a service for healthcare prof...

This work presents a model-driven design process, by which our research team successfully developed a cross-platform system to support an innovative service in short time. Essentially based on co-design and agile development approaches, we applied methods and models developed in user experience design, marketing management and software engineeri...

The development and widespread market acceptance of recent technological devices, such as smart phones and tablets, poses new challenges and great opportunities for innovative service designs. In fact these devices no longer merely replicate the same functionalities in different contexts, they can also dynamically interact among themselves when in...

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 re...

Service design is a multidisciplinary human-centered field that involves a deep understanding of people, context, service providers, market strategies, and social practices, with the aim of designing service offerings that enable customers to co-create valuable experience. To deal with the complexity of service design challenges there is a need to...

These tutorials discuss the following: cyberspace terrorism; EEG-enabled personalized digital experience; and nontraditional modelling.

A modeling tool not only helps users express their ideas and thoughts but also serves as a communication platform among domain experts, designers, developers, and others practitioners. Existing modeling tools have shortcomings in terms of supported functionality and situated usability or do not meet the needs of users of varying levels of expertise...

A proposed approach adapts use-case point (UCP) estimation to agile development of interactive software. To create product cost estimates early during development, developers must agree on the concepts driving the estimations and rely on substantial data from past projects, along with constant feedback and fine-tuning. To enhance the estimations' c...

The proliferation of complex service systems raises new challenges for service design and requires new methods. Multilevel Service Design (MSD) is presented as a new interdisciplinary method for designing complex service systems. MSD synthesizes contributions from new service development, interaction design, and the emerging field of service design...

Human activity modeling is a systematic approach to organizing and representing the contextual aspects of tool use that is both well-grounded in an accepted theoretical framework and embedded within a proven design method. Activity theory provides the vocabulary and conceptual framework for understanding the human use of tools and other artifacts....

In this panel, we propose to figure out how requirements engineering and interaction design can be usefully combined. In particular, some people argue that scenarios/ use cases should be concrete, as in story-telling. Others argue for use of "essential" use cases as a methodological approach to interaction and user-interface design. Somewhat in the...

The theory of family paradigms provides an integrative framework for under-standing and systematizing the diverse ways that families organize and make sense of family life. Using formal methods of analysis based on logical and geometrical arguments, the priecise implications of models of family types can be investigated and compared. The paradigmat...

Marital paradigms comprise the guiding images that serve as reference models for a couple's relationship. Such individualized images can be understood as variations on a small set of basic themes. An understanding of clients' marital paradigms can help foeus treatment on the most appropriategoals usingapproaches and techniques that are most effecti...

An overview is constructed of a substantial array of space and action techniques of broad utility in marriage and family therapy. Family sculpture and a variety of closely related techniques have gained wide acceptance by counselors, therapists, and educators. The roots of these techniques and their basic concepts are traced. A heuristic typology i...

For an effective design one needs to understand the users and their needs. The user-centered design (UCD) models of one type or another are the medium for the message information in most of the designing methods. Models function as intermediaries between the often ambiguous, overwhelmingly complex, reality of actual users and the more narrowly focu...

Peer reviews are developed for chasing down software bugs, auditing against requirements, and ferreting out architectural laws. Peer reviews are also being developed for reviewing other inspection techniques and improving various aspects of the quality of software, including usability. Collaborative usability inspections are highly specialized form...

The purpose of this note is to define the phenomenon under current study in the Multilateral Relations Study Project and differentiate it from certain other related but different sociological phenomena. Confusion in the area of alternative family structures is all but universal, even among professionals and researchers. While definitions that are o...

Various improvements for user-centered design (UCD) are discussed. Collaborative usability inspection is a systematic technique developed and refined specifically for identifying usability defects. Through a highly structured procedure with explicit rules and highly refined roles, collaborative usability inspections identify usability problems more...

Abstract user interface prototypes offer designers a form of representation for specification and exploration of visual and interaction design ideas that is intermediate between abstract task models and realistic or representational prototypes. Canonical Abstract Prototypes are an extension to usage-centered design that provides a formal vocabulary...

Usage-centered design is described and compared with traditional user-centered approaches in relation to software engineering and development. Experiences in integrating usage-centered design with software engineering across a spectrum of process and project models are reviewed. Successful techniques for mitigating the effects on time and resource...

is a functional metaphor. More often than not the store is only an implicit metaphor while the shopping cart may or may not be represented literally in some form. Silly Simulation Problems in usability arise from the misuse of metaphors, and metaphors can be misused in more than one way. Some of the worst abuses of metaphor arise Constantine & Lock...

The Educators' Symposium is a unique forum for educators from both academia and industry who have a vested interest in OO education and training. The Educators' Symposium facilitates the exchange of ideas in a number of ways, including featured talks ...

The HIPO Hierarchy chart is being used as an aid during general systems design. The considerations and techniques presented here are useful for evaluating alternatives for those portions of the system that will be programmed on a computer. The charting technique used here depicts more details about the interfaces than the HIPO Hierarchy chart. This...

The key to making object technology work isn't technology. So what is it? This panel will cover a lot of the "soft" issues about dealing with people and teams. It's partly about managing software development, and mostly about doing it.

Anthropology is the study of civilization, particularly its societies, customs, structure, and evolution. Our premise is that there are cultureal "chasms" to be crossed to ensure the success of the technological beachhead established by innovators and early adopters of the OO paradigm. Our panelists will address the following questions:•What anthro...

The theory of organizational paradigms provides organization development (OD) professionals with a framework for understanding organizational diversity and for fitting interventions and developmental work to each organization's basic nature and operating assumptions. Organizations can be seen as human systems, governed by specific mechanisms and gu...

The object-oriented paradigm still faces an open challenge: Delivering huge software systems routinely and cost effectively. To quote Ed Yourdon: “A system composed of 100,000 lines of C++ is not be sneezed at, but we don't have that much trouble developing 100,000 lines of COBOL today. The real test of OOP will come when systems of 1 to 10 million...

Adolescent behavior and development are generally recognized as mediated, in part, by family process. Based on research and clinical experience, a framework has been developed that organizes the diversity of family styles and structures into fundamental themes, or family paradigms, around which family process can be organized. Following work of Kan...

The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior. In the synchronous paradigm, calm agreement and harmonious unity of action are valued above all. The concept of synchronous operation was first formulated by C...

Computer-aided assessment (CAA) is the use of computers to assist or simplify measurement and evaluation in research and clinical practice. In the family field, potential applications range from simple computer simulations of standard paper-and-pencil measures to sophisticated new assessment techniques using computer graphics or interactive dialogu...

A theoretical model of human systems is presented based on the basic paradigms upon which families, groups, and social systems can be organized. Four fundamentally distinct paradigms are described and the interrelationships among them explored, with special consideration given to the social evolution of systems organized on these paradigms. Implica...

The “open family” model is widely used as a point of reference for healthy family functioning, but potential dysfunctional aspects of open families are not well understood. A unified theory is used to integrate diverse typological models of families to build a composite clinical picture of the disabled open family. The disabled open family is found...

Open family systems are frequently modeled as inherently functional or healthy; however, systematic research and theoretical consideration of potentially dysfunctional patterns is lacking. Using an expanded, integrating theory to bridge gaps among other models, a composite profile of failure and dysfunction in open family systems can be constructed...

Although the research on the effects of childhood incest experiences and sexual encounters with adults is still limited, some consistent trends emerge across studies. Such sexual experiences may be traumatic, inconsequential, or possibly even positive. There does not appear to be any basis established by research for regarding the determinants of t...

Comments on an article Melvin J. Guyer (see record 2013-42233-009). The authors explore explores many of the important issues at the interface between psychotherapy and the law would like to raise several more for discussion. In family treatment, the child a already a client. In much of Guyer’s discussion, the child is regarded as a third party; it...

An integration of theories of family process under a recently formulated unified theory is proposed. Research was conducted testing hypothesized interrelationships between two models subsumed under the unified theory: Satir's model of defended communication and Kantor and Lehr's psychopolitical model of family process. Behavioural ratings from an A...

A model is presented for an alternative family form which extends key ideological and structural features of open marriage to include children. Open families are characterized by enhanced permeability of internal and external boundaries and by commitment to a single standard of behavior for all members regardless of age, sex, or biological relation...

A family-therapy training program, one of three main branches of the "Boston model," is described in detail. Salient features of the program include planned integration of a multiplicity of experiential and cognitive learning modes; grounding in a unified, theoretical framework that is neither eclectic nor limited to a single school of thought; foc...

The HIPO Hierarchy chart is being used as an aid during general systems design. The considerations and techniques presented here are useful for evaluating alternatives for thos portions of the system that will be programmed on a computer. The charting technique used here depicts more details about the interfaces than the HIPO Hierarchy chart. This...

Group or multilateral marriages and other alternative marital patterns are increasingly common. Dissolution of these extralegal relationships can yield insight into conventional marital break-ups. Typically, previous marital dyads remain together after group dissolution. Both typical and atypical patterns suggest that even complex marital relations...

Counselors may expect an increasing number of marriages to include open intimate involvement with others either as an adjunct to the marriage or as an integral part of it. Some elements of these marital styles are extensions of the more conventional dyadic relationship but others appear to be relatively unique or to require a new focus. Key problem...

prototypes are an intermediate form that can speed the user interface design process and improve the quality of the results. Abstract prototypes help bridge the conceptual gap between a task model and a representational paper prototype for a user interface design. This short article introduces abstract prototypes in the form of simple content inven...
