Digitalization and sustainability: virtual reality tourism in a post pandemic world
2022
The government-imposed COVID-19 pandemic control measures brought the tourism sector to a complete halt. However, virtual reality (VR) tourism offered people a way to escape the isolation. Media reports and research have noted heightened activity in VR tourism, which has been touted as “alternative tourism” and “eco-tourism”. However, scholars have yet to determine whether this shift is temporary or will persist after the pandemic is over. Questions also remain regarding the factors driving this behaviour. The present study uses stimulus-organism-response theory (SOR) to propose a sequential mechanism of the interplay of antecedents and outcomes, theorising VR tourism as a sustainable touri…
Big bounce and future time singularity resolution in Bianchi i cosmologies: The projective invariant Nieh-Yan case
2021
We extend the notion of the Nieh-Yan invariant to generic metric-affine geometries, where both torsion and nonmetricity are taken into account. Notably, we show that the properties of projective invariance and topologicity can be independently accommodated by a suitable choice of the parameters featuring this new Nieh-Yan term. We then consider a special class of modified theories of gravity able to promote the Immirzi parameter to a dynamical scalar field coupled to the Nieh-Yan form, and we discuss in more detail the dynamics of the effective scalar tensor theory stemming from such a revised theoretical framework. We focus, in particular, on cosmological Bianchi I models and we derive cla…
