Safety is considered as some of the most important operational characteristics of contemporary civil aviation. An extensive regulatory structure has been established to supplement the private airline, airport and air navigation systems, incentives to limit the risks of flying. This paper reviews the research on risk and safety modelling in civil aviation. In such a context, the basic concepts and definitions of risk, safety and their evaluation are described. The review focuses on four categories of models for safety assessment: causal for aircraft and air traffic control/management operations, collision risk, human factor error and third-party risk. 相似文献

Metaverse is the next disruptive technology that will impact society in the coming decades, by enabling immersive experiences in both virtual and physical environments. Although still conceptual, Metaverse converges the physical and digital universe, allowing users to seamlessly traverse between them. Digital immersion offers opportunities for people to travel in time, supporting users to experience virtually ancient encounters, space explorations or dangerous natural phenomena, such as volcano eruptions. Users can explore immersive environments for working, learning, transacting, exploring interests and socialising with others. This is already evident in gaming ecosystems, where gamers effectively interact in the metaverse. Although still experimental, Metaverse is expected to revolutionize travel and tourism management and marketing. It empowers destination awareness, positioning and branding, as well as coordination and management, through digital twins. Metaverse provides opportunities to support trip planning, interaction and engagement, effectively transforming consumer behaviour. Visiting and engaging with destinations virtually is expected to motivate real travel, rather than replace it. This paper provides a vision of how Metaverse can revolutionize tourism experiences and transform tourism management and marketing. Drawing on a systematic review of scholarly works, articles from media and industry reports, this study defines and conceptualizes the Metaverse ecosystem for tourism and travel. It explores the foundations of the disruptions that Metaverse brings to tourism destinations and organisations and identifies the building blocks of Metaverse tourism. The study outlines research directions so that the tourism industry can take full advantage of the Metaverse capabilities and opportunities emerging as well as identify challenges for the future. 相似文献

This article investigates the impact of social capital and institutions on innovation outcome in Russian regions in 1997–2011. The novelty of the article also lies in the use of two metrics of innovation: the number of new technologies developed and patents filed. The findings provide strong support for the argument that social capital (proxied by social tension) and institutions (proxied by institutional potential) influence innovation activity. Furthermore, different types of innovation outcome are affected differently: the effect of social tension on technology development is significantly negative but insignificant with patenting, while institutional potential affects patenting negatively but its effect on technology development is insignificant. 相似文献

Only anecdotal evidence exists that ventures use patents as collateral to access debt financing. In this paper, we use a novel dataset on patent reassignments with a security interest to explore quantitatively what patents are used as collateral. We analyze characteristics of patents to disentangle whether it is the technology underlying a patent or the patent's exclusion right per se matters for collateralization. We do find empirical support only for technology-related characteristics, suggesting that lenders use patents to collateralize high-quality technology that can, in case of default, be redeployed to ventures in similar technology fields. On the other hand, patent-related characteristics like scope, which are, in general, related to patent value and are particularly important for non-practicing entities, do not matter. 相似文献

Brick and mortar stores are suffering the dramatic revolution of the retail sector. Customer facing in-store technologies (CFIST) are a key component of the inevitable transformation of retail stores; yet the reasons to adopt such technologies by business owners may be little known. Based on a TOE and TAM inspired framework, this study analyses the drivers of such decision by small and medium size enterprises using a survey methodology. The results show that the attitude towards technology is the strongest predictor of the intention to adopt CFIST, highlighting the role of the top management in technology decisions. This conclusion has important implications for practitioners. This research is the first to address the adoption of CFIST by SMEs and therefore set the path for further studies about the impact and adoption of in-store technology in SMEs. 相似文献

Today, brick-and-mortar retailers with integrated online shops have many alternatives to increase their customers’ shopping satisfaction: They could invest in (for the retailers) new physical store technologies (e.g., beacons or magical mirrors if not implemented up to now), new online shop technologies (e.g., visual tagging or webcams), or in new less technology-based improvement options (e.g. events or product testing). We propose an adapted Kano based stage-gate approach to support multichannel retailers confronted with such selection problems. The approach is applied to a major European sporting goods retailer. 37 improvement options are pre-selected and evaluated by current and potential customers. It can be shown that instore returns, instore services, reserve&collect, click&collect, customization, product testing, and magical mirrors are drivers of satisfaction for the current customers and should be implemented in contrast to, e.g., geofencing or beacons. The potential customers are more technology-savvy, but show similar categorizations as a current customer segment and so confirm the selection. 相似文献

ABSTRACTThis article addresses the gap in research on visual and narrative persuasion in online fertility marketing contexts and reveals their reliance on rhetorical ruses embedded in the language of “choice” and “empowerment”. We assess four websites targeting women and men who have experienced infertility and expose their “digirhetrickery”, or use of deceptive rhetoric in digital space which exploits gendered stereotypes of the female body in ways that ultimately mislead their target markets about assisted reproductive technologies (ARTs) and the “liberatory” potential they offer. We advance digital rhetoric as an analytical method to the field of consumer research in order to engage in a reflexive analysis that reveals these underhand ideological operations. As “authorial voices” and narrative agents in digital advertising discourse are more cunningly subterranean, this study shows how the instrumentalization of “consumer empowerment” has become increasingly hyperbolic with particularly problematic consequences for infertile women consumers. 相似文献

Recently booming academic interest in digital transformation aims to provide continuous support to managers in dealing with this important issue. However, as with all new fields, the scholarly literature is characterized by increased variability and diversity of topics covered, constructs used, and the relationships between them, resulting in an unclear and blurry understanding of the whole of digital transformation. Our article closes this gap by identifying distinctive digital transformation strategies in terms of two critical dimensions: usage of digital technologies and readiness of a business model for digital operation. The result is a typology of four generic digital transformation strategies that essentially differ in the primary motivation and target of transformation, leadership style, importance of skills like creativity and entrepreneurial spirit among employees, risks and challenges faced in the process, consequences of potential failure, and available tactics for improvement. By providing heuristics and a systematic basis for comparison of different strategies, it is our belief that the proposed framework will be useful to researchers and managers responsible for and interested in digital transformation. 相似文献

农村失独家庭是不容忽视的庞大群体,再生育问题对和谐家庭、和谐农村以及和谐社会的构建意义重大。农村失独家庭的再生育权应包括再生育自由权、再生育方式选择权、再生育受助权等内容。针对农村失独家庭再生育存在的问题,应由国务院依据《中华人民共和国人口与计划生育法》等相关上位法制定专门的单行条例,并应将再生育自由权保障机制、再生育方式选择权保障机制、再生育受助权保障机制的构建作为条例的重要内容。 相似文献
