CIL's experience with a computerized ammonia plant trip system

The computerized trip system has been in use since August, 1985, at the CIL Ammonia II plant. Superior reliability, essential avoiding unnecessary shutdowns, while protecting the plant from accident, is obtained through use of a fault-tolerant configuration.     

Significant Issues for the Future of Product Innovation

Product innovation management, by definition, requires that we become comfortable dealing with change. As this journal enters its eleventh year of publication, the editor-in-chief asked each member of the editorial board to reflect upon changes and opportunities that they see influencing our profession during the coming decade. In our first installment of these essays, George Day, Bela Gold and Thomas Kuczmarski discuss the value of managing ideas, embracing a longer-term view of development opportunities, and creating a senior executive position charged with developing such opportunities. Each of these short essays is designed to introduce new perspectives. It is not essential that you agree with the recommendations, but we hope that you are stimulated as you reflect on the issues they present.     

Sustainable tourism development and residents’ perceptions in World Heritage Site destinations

Set in Malaysia’s Lenggong Valley World Heritage Site (WHS), this paper uses stakeholder theory to explore the heterogeneity of positive and negative perceptions among residents and their effects on residents’ support for and participation in sustainable tourism development. Data from 221 completed questionnaire surveys revealed heterogeneous negative perceptions across residents’ age, level of education and economic involvement in tourism. Moreover, residents’ positive perceptions had a positive effect on their support for and participation in tourism development. This study contributes to the resident perception literature by using stakeholder theory to conceptualise the heterogeneity of residents’ perceptions and by examining the effects of those perceptions on their support for and participation in tourism development in a rural WHS destination in the developing world. Furthermore, the findings of this study have practical implications for local authorities aiming to improve residents’ support and participation in tourism planning for sustaining tourism development.     

Learning through engagement: undergraduate students engaging in community-based participatory research (CBPR) in hospitality and tourism education

This paper discusses how instructors can engage their students in community-based participatory research (CBPR) projects that involve not only research on a topic but also include community stakeholders in the research process and provide opportunities for service learning. CBPR is defined, examples of effective CBPR student projects are presented, the possible benefits and drawbacks of CBPR student projects are offered, and tips for conducting successful CBPR projects with hospitality and tourism students are provided.     

Environmental scanning the future of event design

This paper used multiple sources of information in order to identify the forces likely to impact event design. Content analysis of key informant interviews and selected trade publication articles identified key forces impacting event design. Technology, the environment and green issues, security and safety, and globalization were forces identified by both the key informants and the trade literature. Neither of the sources gave much attention to political forces. This article contributes to our understanding of the forces impacting event design and suggests some environmental scanning methodologies that can be used with both key informants and the trade publication literature.     

The impact of mood states and surprise cues on satisfaction

Mood effects have been studied in consumer behavior literature, but prior research investigating the joint impact of mood and surprise on satisfaction is scant. To bridge this gap, this study examines the relationship among these three constructs. We manipulated customers’ pre-consumption mood and provided surprise cues with hypothetical scenarios in a 2 by 2 factorial design in a restaurant setting. The results show that a positive surprise yields high satisfaction without a significant effect from customers’ pre-consumption mood. Conversely, with a negative surprise, customers in a negative pre-consumption mood indicate lower satisfaction than those in a positive mood.
