This article introduces a Valuation Studies approach, in which valuation is seen as a social practice, to studying the outcomes of events. Drawing on material gathered around the Arctic Winter Games organized in Nuuk, Greenland in 2016, we exemplify how researchers working together across disciplinary and methodological boundaries can engage together with events stakeholders in making event values knowable beyond the confines of traditional evaluation. Analytically, we use Callons’ concepts on framing and overflows to exemplify alternative outcomes of events. We argue that a valuation approach offers an iterative understanding of event outcomes which encourages economics and constructivist research to collaborate on exploring event worth and making event overflows knowable and valuable. 相似文献

The rapid development of information communication technology has encouraged tourism authorities to carefully consider the typical duties of tourist information centres (TICs), wherein visitors acquire various kinds of travel information about a particular destination. This study aims to provide useful management implications to help tourism organisations develop feasible TIC operational strategies and implement alternative services in the ubiquitous information environment. To provide a richer understanding of tourists' heterogeneous preferences for TICs, this study makes use of the stated preference choice method with a sample of South Korean domestic tourists. Despite the widespread use of personal mobile devices, our study results suggest that South Korean domestic tourists still prefer to visit various types of TICs to acquire travel information. Results indicate that the TIC visitor group is less sensitive than the non-visitor group to advanced information communication technology and more satisfied with the availability of WIFI signals to facilitate the use of personal mobile devices or laptops. Our respondents also demonstrate their preferences for some TICs constructed with container structures, whereas they showed a strong aversion to visiting booth-styled TICs inside larger buildings. Based on these findings, this study provides several management strategies to fulfil tourists' ever-changing needs. 相似文献

This study examines the role played by submission devices (mobile vs. desktop) in online travel reviewing behaviour. We analyse over 1.2 million online reviews from Booking.com and detect the presence and distinctive features of online reviews submitted by mobile devices. Our findings indicate that 1) the share of online reviews submitted by mobile increased at a very high rate over time (higher than the growth rate of those submitted by desktop); 2) there is a systematic and statistically significant difference between the features and distributions of online reviews submitted through mobile devices vs. online reviews submitted through desktops. We raise awareness of the role played by submission devices in online travel behaviour research and present implications for future research. 相似文献

随着社会的工业化进程加快,机动车、电厂废气等人为因素产生的NO2日益增多。NO2虽然对臭氧的形成有重要作用,同时也会导致酸雨的形成,所以检测NO2的浓度在很多领域有着重要意义。本文以NO2为检测对象,对其不同频率响应采用两种传感器进行初步实验并进行比较分析,声表面波传感器是利用沿着物体表面传播的弹性波来感测信号的,而磁弹性传感器是由外加磁场对磁弹性材料的作用来感测信号的,两种传感器的响应信号都是频率偏移,在实验中,传感器的频率响应采用网络分析仪测试。实验结果表明,磁弹性传感器相对于声表面传感器对NO2的吸附前后频率响应更明显,对相关领域的研究更具实际意义。 相似文献
