Abstract

This paper looks at a number of approaches to health informatics that support decision‐making relevant to the integrated development and management of information systems with clinical and managerial practices in healthcare. Its main aim is to explore three such approaches for integrated development, the soft information systems and technologies methodology, participative simulation modelling and stakeholder analysis. A description of the health informatics research and development environment in the UK is given as necessary background to the paper. Organisational and social aspects are examined through these approaches including information and clinical process development, telemedicine, ethical issues of drug use and management, health policies and information management and strategies, tele‐education and modelling structures. In the conclusion the synergies between the three approaches are discussed and some principles are extracted for future research and development in integrated approaches to health informatics research.

Abstract

Purpose

Most manufacturing processes tend to involve more than one level of detail at the design phase. These often consist of a higher level that represents the building‐blocks of the firm and a lower level that represents a more detailed structure of the process. When designing such processes, this type of structure is difficult to capture without some form of modelling. In such cases simulation can be used to help overcome this problem. This paper presents an investigation of simulation packages.

Design/methodology/approach

These simulation packages were investigated regarding their abilities to model business processes related to manufacturing systems.

Findings

The research findings suggest that no one simulation package currently available can alone offer sufficiently flexible facilities for the variable detailed modelling of manufacturing systems design.

Originality/value

The paper relates to one specific design framework called manufacturing system design (MSD). It defines the higher level of detail as the conceptual modelling level and the lower level as the detailed design level. A four‐step framework is proposed, and it is argued that this may better deal with problems of detail variability.

Abstract

Discrete event simulation (DES) is widely known to be a quantitative research tool. A simulation modelling process is mainly based on feeding quantitative data into a model to produce quantitative results in a structured sequential process. Qualitative approaches to research take a less structured approach with more of an inclination towards judgmental and expert knowledge rather than hard data. In this paper the authors suggest that DES can be employed as both a qualitative and quantitative research tool. The paper demonstrates how simulation may represent both stances either separately or combined. This is based on the fact that the basic objectives of simulation are either for understanding – which needs a qualitative perspective – or performance measurement – which a needs quantitative perspective. Traditional quantitative and qualitative methods are discussed showing how DES might cope with the weaknesses of both stances. A structure for using DES as a combined research methodology is proposed.

Abstract

Discrete event simulation (DES) application is not as widely perceived as being useful for problem solving in the health‐care arena as in other application areas. Suggests that this might be due to the way DES is applied in health‐care modelling, as it follows a traditionally based‐on‐engineering approach. This may not be a problem in itself; however, health‐care systems are often complex in that they involve multiple decision‐makers and thus understanding and communication between the various stakeholders are potentially problematic. Thinks that problem understanding and efficient communication tools largely contribute to the solution; consequently, proposes a modelling approach to enhance stakeholder understanding and communication. The approach is based on participation of stakeholders; it is also iterative rather than step‐based. To demonstrate this approach, gives an example, aiming to show how this approach has been used successfully to facilitate the understanding process, concluding that involving stakeholders throughout not only helps them to understand their problem better, but also enables them to more fully appreciate the findings resulting from the model. This approach thus serves usefully to enrich the communication between the stakeholders.

Abstract

NEXIS and DIALOG both offer full‐text online coverage of the magazine Business Week, while ABI/INFORM Global Edition on CDROM provides abstracts. A comparison of all three systems shows mixed results. DIALOG had the most records for two narrow topics, while NEXIS was superior when the search topic was broader. Although retrieving fewer items than the full‐text systems, ABI/INFORM had a considerable amount of material. With the difficulty of choosing between costly full‐text systems, settling for abstracts on CDROM may be an alternative for the researcher.

Abstract

Notes that patients attending public outpatient departments in Hong Kong spend a long time waiting for a short consultation, that clinics are congested and that both staff and patients are dissatisfied. Points out that experimentation of management changes in a busy clinical environment can be both expensive and difficult. Demonstrates computerized simulation modelling as a potential tool for clarifying processes occurring within such systems, improving clinic operation by suggesting possible answers to problems identified and evaluating the solutions, without interfering with the clinic routine. Adds that solutions can be implemented after they had proved to be successful on the model. Demonstrates some ways in which managers in health care facilities can benefit from the use of computerized simulation modelling. Specifically, shows the effect of changing the duration of consultation and the effect of the application of an appointment system on patients’ waiting time.

Abstract

Purpose

This paper describes the personal history and intellectual development of Morris B. Holbrook (MBH), a participant in the field of marketing academics in general and consumer research in particular.

Design/methodology/approach

The paper pursues an approach characterized by historical autoethnographic subjective personal introspection or HASPI.

Findings

The paper reports the personal history of MBH and – via HASPI – interprets various aspects of key participants and major themes that emerged over the course of his career.

Research limitations/implications

The main implication is that every scholar in the field of marketing pursues a different light, follows a unique path, plays by idiosyncratic rules, and deserves individual attention, consideration, and respect … like a cat that carries its own leash.

Originality/value

In the case of MBH, like (say) a jazz musician, whatever value he might have depends on his originality.

Abstract

Corporate downsizing has destroyed millions of well‐paying jobs just in the USA. The psychological, medical, and social costs are staggering. Families are fragmented, communities impoverished, democracies weakened by oligopolistic, plutocratic corporarchies, and Third World nations recolonized and their subsistence economies decimated. Most of the employee survivors of this economic and class warfare are working longer and harder and are suffering various stress, burnout, and psychiatric symptoms. In addition to intense global competition, cheap foreign labour, and superefficient technologies, there are psychocultural factors contributing to the “jobless economy”: executive ambition, greed, power‐lust, and winner‐take‐all ideologies. Solutions include changes in tax and other federal policies, restrictive corporate charters, shorter workweeks, community development programmes, and co‐operative, employee‐owned enterprises. The learning organization and fourth‐wave business suggest an evolutionary paradigm for the twenty‐first century based on global responsibility, economic justice, a new bottom line, and a restoration of meaningful, sustainable work.

Abstract

Previous research has not addressed the problem of developing a master production schedule (MPS) for production systems with minimum batch‐size production restrictions. Proposes a weighted integer goal‐programming model for the development of a rolling horizon master production schedule, under conditions of demand certainty, for a process industry environment with multiple production lines and minimum batch‐size production restrictions. The presence of multiple and often conflicting goals prevalent in production planning and scheduling is explicitly incorporated in the model. The model can easily be implemented on a microcomputer and the master production schedule developed is in spreadsheet format and can easily be understood by a practitioner. Uses a case study conducted for a paint company to illustrate and validate the model. Results show that the MPS developed using the proposed model is superior in terms of total cost when compared with actual company performance.

Abstract

This paper argues that enterprise scale information systems integration should be driven by business value propositions rather than system level requirements. It reviews the existing literature of value and presents a summary of the issues and insights. A study of attitudes and perceptions from an enterprise system vendor organisation is presented. The study uses cognitive mapping to analyse the data and grounded theory to derive the concept of value proposition as a suitable concept for comprehending integration. The concept is further developed from a synthesis of the issues from literature with the results. The determination of a value proposition is argued to be a process of defining the consumer and providing perspectives. The provider perspective of value proposition is shown to be competency based whilst the consumer is results oriented. Discussion of the implications of value proposition driven integration projects leads onto recommendations for industry and implications for further academic research.
