A hedonic motivation model in virtual reality tourism: Comparing visitors and non-visitors

Virtual reality (VR) tourism provides consumers with the opportunity to experience a destination in VR and can play a significant role in encouraging visitation and engaging in particular travel activities and behaviors. Hedonic motivation adoption frameworks with flow state and subjective well-being have been shown to have significant roles in continued use of information technology. However, research on a theoretically integrated hedonic motivation system adoption model (HMSAM) specifically with enjoyment, flow state, subjective well-being, and continued use has not previously been conducted with respect to VR tourism. To address this gap, this study develops and investigates a conceptually comprehensive model on the effect of consumers’ hedonic behaviors on continued use, with the moderating role of visitor or non-visitor at the destination portrayed in VR tourism. Results identified the highly significant effect of consumers’ perceived enjoyment on flow state and of flow state on subjective well-being. Continued use was greatly influenced by flow state and subjective well-being. Importantly for destinations association between usefulness and flow state had a significant moderating effect depending on whether a visitor or non-visitor. The findings offer new knowledge to researchers and industry in the VR tourism fields.     

Assessing volunteer satisfaction at the London Olympic Games and its impact on future volunteer behaviour

Abstract

In recent years, volunteering has received strong research attention from both scholars and practitioners. For the most part, involvement in volunteer activities has been identified as an important determinant of future volunteering. Through revalidating an existing instrument, the purpose of this study was to assess the dimensions of volunteer satisfaction at the 2012 London Olympic Games and its impact on future volunteer behaviour. The findings of this study shed light on the identification of volunteer satisfaction factors in the mega sporting event setting, particularly for a unique type of volunteer (i.e. media worker) assigned to a special set of tasks. Unlike Galindo-Kuhn and Guzley’s results that revealed participation efficacy and group integration to be strong predictors of volunteer satisfaction, organizational support was the primary predictor for media centre volunteers’ re-participation intention towards future volunteering programmes.     

MARC to BIBFRAME: Converting the PCC to Linked Data

Abstract

The Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data.
