The purpose of this chapter is to examine the presence of abuse enacted through virtual mediums with a specific focus on how athletes can become the targets of online hate. The chapter introduces social media and explores the role it has played in the increasing reliance on virtual worlds. The impact of digital technology on sport in particular is framed in order to demonstrate how digital technologies are now a vital component in our consumption of sport. The primary focus of the chapter is on how virtual spaces can pose significant risk(s). Freedom of speech, shifting power and the lack of safety and regulation in virtual spaces are all presented. Finally, recommendations are made for future research in the area in order to develop understanding of abuse augmented by virtual environments and to develop the focus on virtual safeguarding in sport and beyond.

This chapter synthesises and discusses existing literature from the disciplines of sport, social media and abuse, with a view to understand and address prominent issues encountered by athletes in the virtual world.

By examining abuse through a sociological lens, this chapter focusses on the factors that promote or enable abuse to occur online (often without regulation). The types of abuse experienced in virtual spaces are legion and this adds to the complexity of policing and/or safeguarding online environments.

The chapter makes recommendations for a number of future areas of study that will extend the current understanding of abuse in virtual environments.

The chapter provides a synthesis of the emerging area of virtual abuse and its links to sociology as a discipline. It offers insight into power in virtual spaces as a critical frame of reference for understanding virtual interactions and parasocial relationships.

Polymer laser powder bed fusion (PBF-LB/P) is an additive manufacturing technology that is sustainable due to the possibility of recycling the powder multiple times and allowing the fabrication of gears without the aid of support structures and subsequent assembly. However, there are constraints in the process that negatively affect its adoption compared to other additive technologies such as material extrusion to produce gears. This study aims to demonstrate that it is possible to overcome the problems due to the physics of the process to produce accurate mechanism.

Technological aspects such as orientation, wheel-shaft thicknesses and degree of powder recycling were examined. Furthermore, the evolving tooth profile was considered as a design parameter to provide a manufacturability map of gear-based mechanisms.

Results show that there are some differences in the functioning of the gear depending on the type of powder used, 100% virgin or 50% virgin and 50% recycled for five cycles. The application of a groove on a gear produced with 100% virgin powder allows the mechanism to be easily unlocked regardless of the orientation and wheel-shaft thicknesses. The application of a specific evolutionary profile independent of the diameter of the reference circle on vertically oriented gears guarantees rotation continuity while preserving the functionality of the assembled mechanism.

In the literature, there are various studies on material aging and reuse in the PBF-LB/P process, mainly focused on the powder deterioration mechanism, powder fluidity, microstructure and mechanical properties of the parts and process parameters. This study, instead, was focused on the functioning of gears, which represent one of the applications in which this technology can have great success, by analyzing the two main effects that can compromise it: recycled powder and vertical orientation during construction.

This paper aims to discuss the evolution of tourism data and critically debates future perspective for producers and users of tourism data.

This paper provides a perspective on tourism data based on selected literature.

Industry developments, technological changes and novel methodologies have influenced tourism data sources. Closer attention to new data collection methods and novel analytics is required.

A considerate and integrated system of tourism data (statistics, indicators, and big data) shall remain a priority for scholars and practitioners alike.

The thoughtful merging of tourists’ digital traces with industry data, the competences of data analysts and the theoretical strengths of tourism scholars will result in a redesign of the tourism data landscape.

This perspective article provides a brief overview of the development and challenges related to the future use of tourism statistics, indicators and big data.

The paper offers a novel vision of tourism data by combining three different but complementary aspects of tourism data.

The purpose of this paper is to develop a holistic understanding of extant studies addressing the impact of commercialization on fans of elite sports.

In doing this, the authors performed a structured review of 42 academic articles published between 1992 and 2020 that all focus on how fans respond and are affected by the commercialization of elite sports.

The structured review shows that the impacts of commercialization on fans relate to four different themes. These are (1) fan identity, (2) fan attitudes, (3) fan emotions and (4) fan behaviours. However, the analysis also shows that research within each category is largely scattered, and more research within each category is needed.

The paper highlights the complex and dynamic nature of commercialization. It presents a research agenda for future research and emphasizes a need to integrate the interests of several stakeholders when managing the impacts of elite sport commercialization.
