This article describes the origins of the work system model and the Balance Theory, which were developed as a way of integrating knowledge about work from various bodies of literature: job/organizational design, job stress, and human factors and ergonomics. Key concepts of the Balance Theory are reviewed. The work system model and associated design principles are described. Originally, the Balance Theory emphasized the impact of work on job stress; other worker outcomes were later described such as job satisfaction, and worker health, safety, and well-being. In conclusion, the article describes four emerging areas of application of the Balance Theory: (a) impact of the work system on worker performance, (b) multilevel analysis of the work system, (c) understanding the nonwork sphere, and (d) application to health care and patient safety, also known as the Systems Engineering Initiative for Patient Safety model of work system and patient safety.

Rapid advances in computer technology, and more specifically the Internet, have spurred the use of the Internet surveys for data collection. However, there are some concerns about low response rates in studies that use the Internet as a medium. The question is whether the lessons learned in the past decades to improve rates in postal mail surveys can also be applied to increase response rates in Internet surveys. After all, the Internet is a completely new medium with its own “rules” and even its own (n)etiquette. This article examines 29 studies that directly compared different survey modes (postal mail, fax, e-mail, and Web-based surveys) with more than 15,000 respondents. Factors that can increase response rates and response quality when using Internet surveys, compared to mail surveys, are discussed. Finally, the research that can contribute to increase response rates in Internet surveys is examined.

The purpose of this study was to test the hypothesis that nurses' beliefs about the technology they use in practice would affect their perception of individual and unit quality of care. A survey was administered to 347 pediatric nurses (response rate = 57.3%) from two academic freestanding pediatric hospitals in the United States. Two separate equations were constructed; one tested whether technology beliefs affected perceived individual quality of care, and the other tested whether technology beliefs affected perceived quality of care provided by the nursing unit. Nurse confidence in their ability to use computer technology and their beliefs that the technologies fit task requirements were significant predictors of nurse beliefs that they and their unit were able to provide quality care to their patients.

Elaborating on the rapid evolution of mobile internet services in Korea, this article investigates consumers' perceptions and attitudes toward mobile Internet services through person-to-person questionnaires. The study tried to find out “how” consumers perceived different mobile services from the consumers perspectives: expectation, satisfaction, and fulfillment of that expectation. A new construct of perceived fulfillment of expectation was suggested in the study and used to explain consumers' attitudes toward the mobile Internet services in 2004 and in 2006. After examining what the consumers actually said, it was found that consumers' expectation was fulfilled differently for different service categories. The expectation was more fulfilled in system attributes, that is, network-wise, for personalization and information services, and in contents attributes for entertainment services. It was also observed that consumers of different age groups showed different patterns of fulfillment of expectation with the same services. Even though most of the past studies on mobile telephony concentrated on attitudes and behaviors of teenagers toward the mobile telephone services, the result of this study indicates that the consumers in their 20s and 30s can provide more insight for future directions of mobile Internet services. The newly defined construct could well explain the differences among the various consumer groups' perceptions and attitudes.

Implementation of information systems (IS) in organizations have been a constant challenge. Many organizations still approach IS implementation as a panacea. Lessons learned from the introduction of computer terminals in the late 1970s to enterprise systems in the late 1990s have not been applied consistently. This article makes the case for using macroergonomics in the development and implementation of information systems. It stresses that macroergonomics may increase the likelihood of IS implementation success.

Existing models of usability evaluation estimate sample size requirements based on goal discovery rate and detectability of potential problems without consideration of the importance of the problem and an index of usability, which allows the comparison of the effectiveness of usability of information technology products and services across different domains. This article presents a methodology which accounts for the aforementioned limitations in usability evaluation. A case study is presented, which illustrates the utility of the proposed methodology and indicates that the current methods underestimate the number of participants in usability evaluation studies.

This article outlines issues that emerge from the evolution of the Information Society towards Ambient Intelligence (AmI) environments, focusing on the diversity of human needs, the dynamic evolution of context, and the multifaceted characteristics of interactive technologies. Such an evolution brings forward many implications and challenges in the context of Universal Access, that is, accessibility and usability of Information Society Technologies by all users, independently of individual abilities and characteristics. Identified research challenges include the investigation of human requirements in the context of AmI, suitable approaches to nonfunctional characteristics (such as accessibility, privacy, security, and safety), suitable models of the context of use, appropriate interaction devices and techniques for diverse users and contexts of use, interaction design for continuous and implicit interaction, elaboration of design methods suitable for very complex interactive environments, and mechanisms for interaction adaptation. This article argues that such challenges in the context of AmI environments can be addressed by systematically investigating the interplay between the user, the context, and the technologies. Such a research direction requires systematic approaches to diverse human needs, dynamic context characteristics, and technology possibilities, all of which need to be elaborated and validated in practice.

The fast aging of many societies and their increasing reliance on computers create a compelling need to reconsider older users' interactions with computers. Changes in perceptual and motor skill capabilities that accompany the aging process bring important implications for the design of human–computer interfaces. This study reviews the recent research literature on computer input devices and their adequacy to the elderly user. Significant findings from evaluative studies are summarized, and strengths and weaknesses of the different input devices are outlined. Recommendations for the design and selection of input devices are provided.
