Knowledge transfer in a tourism destination: the effects of a network structure

Tourism destinations have a necessity to innovate to remain competitive in an increasingly global environment. A pre-requisite for innovation is the understanding of how destinations source, share and use knowledge. This conceptual paper examines the nature of networks and how their analysis can shed light upon the processes of knowledge sharing in destinations as they strive to innovate. The paper conceptualizes destinations as networks of connected organizations, both public and private, each of which can be considered as a destination stakeholder. In network theory they represent the nodes within the system. The paper shows how epidemic diffusion models can act as an analogy for knowledge communication and transfer within a destination network. These models can be combined with other approaches to network analysis to shed light on how destination networks operate, and how they can be optimized with policy intervention to deliver innovative and competitive destinations. The paper closes with a practical tourism example taken from the Italian destination of Elba. Using numerical simulations the case demonstrates how the Elba network can be optimized. Overall this paper demonstrates the considerable utility of network analysis for tourism in delivering destination competitiveness.Comment: 15 pages, 2 figures, 2 tables.

Higher Derivative Corrections and Central Charges from Wrapped M5-branes

We compute four-derivative corrections to the AdS supergravity actions arising from the near-horizon geometry of N M5-branes wrapped on either one or two Riemann surfaces. This setup features the novel presence of both gauged isometries as well as nontrivial hypermultiplets. We argue that the 5d Chern-Simons terms receive not only higher-derivative corrections but also contributions from Killing vector parameters, which we find must also be corrected. We check the central charges found by our supergravity methods against the dual field theory results and find perfect agreement at leading and subleading order in N. Along the way, we find higher derivative corrections to general AdS_5 and AdS_3x\Sigma_g geometries.Comment: 32 pages + 16 pages appendice

Metaverse in the tourism domain – introduction to the special issue

In times of technological innovation and digital transformation, the convergence of Metaverse and tourism emerges as a compelling and revolutionary intersection. As we stand on the edge of a new frontier in information technology, we introduce this special issue of the Journal of Information Technology and Tourism, dedicated to the multifaceted exploration of the Metaverse’s impact on the tourism industry. The Metaverse comprises interconnected digital spaces where users can engage through computer-generated environments. This convergence of cutting-edge tech- nologies, including artificial Intelligence (AI) systems, digital twins, augmented reality (AR), virtual reality (VR), blockchain, non-fungible tokens (NFTs), 3D mod- elling and simulation, cloud computing, and edge computing, defines the Metaverse’s potential. The Metaverse’s profound Influence on the tourism domain is well attested by the rigorous examinations, insightful analyses, and innovative research contributions in this issue. As we embark on this exploration, we encourage researchers, scholars, and industry experts to contribute their expertise and insights, forging a path toward a deeper understanding of the Metaverse’s implications for the future of tourism

Metaverse in the tourism domain - introduction to the special issue (part 2)

Metaverse for Tourists and tourism destinations explores how Metaverse and its underlying technologies can reshape the tourism industry, considering both the supply and the demand perspectives. The paper reviews several works on this theme, summarizing the outcomes that present several promising solutions. In Metaverse and Tourism Development: Issues and Opportunities in Stakeholders’ Perception, the objective is to understand how the managers of tourism attractions (archaeological parks, museums, seaside resorts, nature reserves, etc.) face the challenges and the use of digital transformation and specifically how including Metaverse tools in their strategies. The results show the influence of the stakeholders’ perception of the Metaverse and confirm the existence of heterogeneous preferences

Network Analysis Methods for Modelling Tourism Inter- Organizational Systems

This chapter discusses the emerging network science approach to the study of complex adaptive systems and applies tools derived from statistical physics to the analysis of tourism destinations. The authors provide a brief history of network science and the characteristics of a network as well as different models such as small world and scale free networks, and dynamic properties such as resilience and information diffusion. The Italian resort island of Elba is used as a case study allowing comparison of the communication network of tourist organizations and the virtual network formed by the websites of these organizations. The study compares the parameters of these networks to networks from the literature and to randomly created networks. The analyses include computer simulations to assess the dynamic properties of these networks. The results indicate that the Elba tourism network has a low degree of collaboration between members. These findings provide a quantitative measure of network performance. In general, the application of network science to the study of social systems offers opportunities for better management of tourism destinations and complex social systems

Aqua(2,2′-bipyridyl-N,N′)(thiodiacetato-0,0′,S)zinc(II) tetrahydrate

The title complex, aqua(2,2′-bipyridy-N,N′(3-thiapentanedioate-O,S,O′)zinc(II) tetrahydrate, [Zn(C4H4-O4S)(C10H8N 2)(H2O)].4H2O, is mononuclear with a coordination sphere consisting of one S, two N and three O atoms. The Zn atom is linked to a tridentate thiodiacetate ligand, a bidentate 2,2′-bipyridine ligand and an aqua ligand resulting in a slightly distorted octahedral coordination geometry. The molecular units are linked together in the crystal by an extensive hydrogen-bonding network and by intermolecular S⋯S interactions.Fil:Baggio, R. Universidad de Buenos Aires.

The five-coordinate cadmium halide bis(diethyldithiocarbamate) complexes [PPh4][Cd(S2CNEt2)2Cl] and [PPh4][Cd(S2CNEt2)2Br]

The title compounds, tetraphenylphosphonium chlorobis(diethyldithiocarbamato-S,S)cadmium(II), (C24H20P)-[CdCl(C5H10NS 2)2], (1), and tetraphenylphosphonium bromobis(diethyldithiocarbamato-S,S)cadmium(II), (C24-H20P)[CdBr(C5H10NS 2)2], (2), are isomorphous. The compexes are mononuclear with coordination spheres of the types S4Cl and S4Br, respectively. The central Cd atom is linked to four S atoms and two bidentate dithiocarbamate ligands and to the halide atom. The resulting Cd-atom coordination geometry is halfway between trigonal bipyrimidal and square pyramidal.
