Structured packings for use in oxygen service: Flammability considerations

Metallic structured packings have found increasing use in the cryogenic distillation of air. An experimental program was performed to test the flammability of selected metal packings under simulated high oxygen concentration operating conditions. Aluminum flammability in gaseous oxygen has been shown to be very dependent upon argon dilution, and in the presence of liquid oxygen, strong energy releases have been observed. Brass packing exhibited an unexpectedly high relative flammability whereas copper has been found to be non-flammable in all tested oxygen purities. These findings suggest the use of copper structured packing in higher purity GOX/LOX regions of an air separation distillation column and aluminum structured packing in the remainder of the column.     

Can the North American ski industry attain climate resiliency? A modified Delphi survey on transformations towards sustainable tourism

As global temperatures increase, does accelerating climate change represent an existential crisis or a manageable challenge for the ski industry? Despite considerable evidence demonstrating the global ski industry is in the early stages of a climate-induced transition, global research on ski industry stakeholder perspectives shows varied levels of climate risk awareness, a focus on future vulnerability, and limited engagement in adaptation. Within North America, research has focussed on the physical climatic impacts to ski operations and possible skier responses, yet there lacks insight into industry perceptions on current and future climate vulnerability. This study fills this important knowledge gap using a Delphi survey to engage 52 leaders from across the continent in a dialogue on strategic climate responsiveness. Results demonstrate North American ski industry leaders’ climate risk perceptions range widely, and opinions diverge over if or how to respond at both an industry and destination scale. Simultaneously, industry experts believe mountain tourists increasingly value nature-based activities, place-bound products, and corporate responsibility. Analysing industry leaders’ responses through Enlightened Stakeholder theory highlights how aligning supply-side environmental management with demand-side tourist experiences may create opportunities for new partnerships, innovations, policies, and strategies needed to achieve climate-resilient and sustainable futures.     

Types and Amounts of Information Used by Efficient Consumers

This paper describes a research methodology which assesses the efficiency of consumer decision-making based on the types and amounts of informational cues used. A simple operational method is used to classify consumers into three levels of consumer efficiency based on how well they perform in assessing the optimal choice. The information chosen by perfectly efficient consumers, or those scoring at the maximum level of efficiency, is examined for indicators of optimal information seeking and decision-making techniques.     

Religion and identity in India’s heritage tourism

The growing worth of heritage in the renegotiation and dissemination of identities has intensified conflicts over whose voice dominates heritage tourism representations. Therefore, this study compares the way India’s heritage is represented by the Indian government, by the domestic tourism trade media and by the popular tourism media. The findings reveal that India is consistently represented as an ethnically diverse nation in which Hinduism preceded and prevailed over all other ethnicities/religions; a portrayal that consolidates the state’s secular nationalist narrative. Furthermore, the trade and popular media emphasize nostalgic experiences of a sanitized colonial history while the government emphasizes accounts of resistance against colonial powers and of suffering due to Muslim atrocities.     

The Essential Role of Sense of Community in a Youth Sport Program

This multiphased study identifies the salient benefits that parents seek for their families from a youth sport program. Phase 1, a preseason focus group study of parents of swimmers in three clubs (N = 15), indicated parents seek a sense of community for their children and themselves, and sense of community is linked to their desire for children to learn sport and life skills. Phase 2, a postseason survey of parents in the same three clubs (N = 129), tested the relationships among coaching quality, friendships, organizational communication, sport and life skills, sense of community, parents' satisfaction, and their repeat purchase intention. Using path analysis, sense of community was identified as the key driver of satisfaction and repeat purchase intention, with swimming improvement also having a significant effect on satisfaction. These findings highlight the central role sense of community plays for participants and their families in youth sport contexts.     

Home Warranties: An Analysis of an Emerging Development in Consumer Protection

Although warranty coverage on consumer products is a universally accepted form of protection, the extension of similar coverage to buyers of new and used homes is a developing practice. Home warranties serve a dual purpose: they reduce a homebuyer's risk of substantial financial loss, and protect the builder, seller or real estate vendor from legal liability should undisclosed material defects occur after a sale. In an effort to examine consumer reactions to home warranties, a mail survey was conducted of recent purchasers residing in four central counties of New York State. It was found that two-thirds of the 571 single-family homeowners who responded were aware of warranties on new housing and 97 percent were in favor of such coverage. Only 22 percent were aware of warranties for resale homes and 56 percent favored such coverage. Unexpected defects costing more than $100 were experienced by 55 percent of the sample. However, only 27 percent of the sample had defects which were warrantable under most current warranty programs.
