Instructor Presence in a Virtual Classroom
2021
Abstract Synchronous online learning platforms have been used actively during the COVID-19 period. They have opened possibilities for online learning and interaction, but have also posed new challenges for instructors. This article provides insights into one teacher’s interactions and examines how the instructor presence is expressed in the teachers’ activities in virtual classrooms in higher education. Instructor presence is investigated using the social and teaching presence indicators of the community of inquiry (CoI) framework. Twelve hours of interactions across six online classes were recorded, transcribed, and analysed using content analysis. The findings suggest that indicators of t…
From virtual to real healing: a critical overview of the therapeutic use of virtual reality to cope with mourning
2021
In recent years, virtual reality (VR) has been effectively employed in several settings, ranging from health care needs to leisure and gaming activities. A new application of virtual stimuli appeared in social media: in the documentary 'I met you' from the South-Korean Munhwa Broadcasting, a mother made the experience of interacting with the avatar of the seven-year-old daughter, who died four years before. We think that this new application of virtual stimuli should open a debate on its possible implications: it represents contents related to grief, a dramatic and yet natural experience, that can have deep psychological impacts on fragile subjects put in virtual environments. In the presen…
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…
Global Performance Management for Small and Medium-Sized Enterprises (GPM-SME)
2006
This paper refers to the project GPM-SME — FP6-005857i, included within the 6th Framework Programme of the European Commission, in its CRAFT Programme. The goal of this document is to present the main concepts of Global Performance Management and how the GPM-SME consortium pursues to develop a framework to improve the competitive capability of companies and their network visibility, specially developed for Small and Medium sized Enterprises. This main aim will be achieved in two ways: allowing companies to include Innovation potential in their performance management, and defining new ways to share information among companies in Collaborative Networks(CN) and measuring the capabilities of Vi…
Arte digitalizado y arte digital: las manifestaciones artísticas en la era digital
2003
Analizamos las potencialidades que el medio digital ofrece al campo de la creación, constatando la aparición de nuevas obras más interactivas, abiertas y dinámicas y de un nuevo tipo de espectador más activo. Destacamos las repercusiones que este medio está ejerciendo en el mundo de los museos y las galerías que están apostando, en algunos casos, por incorporar estas obras a sus espacios expositivos y al mercado del arte. Reseñamos la importancia de Internet y el surgimiento del net-art, así como de la Realidad Virtual y el Arte evolutivo. (A)

Virtual Currency: New Step in Monetary Development
2016
Abstract Money is perhaps the best recognized and at the same time less understood figure of economy. During the evolution of a monetary science starting from the eighteenth century and fundamental works on such questions as true nature and main functions of money, the approach and theories about monetary science have changed significantly up to date not reaching the final state. The twenty-first century can be characterized with a vast development of technologies and the increase use of the internet which significantly succeeded the development of monetary system introducing a new phenomenon - virtual currencies. While remaining rather illusive, virtual currencies have been broadly noted b…
Complexity traits and synchrony of cryptocurrencies price dynamics
2021
AbstractIn this study, we characterized the dynamics and analyzed the degree of synchronization of the time series of daily closing prices and volumes in US$ of three cryptocurrencies, Bitcoin, Ethereum, and Litecoin, over the period September 1,2015–March 31, 2020. Time series were first mapped into a complex network by the horizontal visibility algorithm in order to revel the structure of their temporal characters and dynamics. Then, the synchrony of the time series was investigated to determine the possibility that the cryptocurrencies under study co-bubble simultaneously. Findings reveal similar complex structures for the three virtual currencies in terms of number and internal composit…
Speculation and Lottery-Like Demand in Cryptocurrency Markets
2020
This is the first paper that explores lottery-like demand in cryptocurrency markets. Since recent research provides evidence that cryptocurrency returns are rather short-memory processes in their nature, we modify Bali et al.’s (2011, 2017) MAX measure and employ a weekly forecast horizon and last week’s daily log-returns for calculating the metric for our portfolio sorts. From an econometric point of view, this study proposes statistical tests that are robust to unknown dynamic dependency structures in the cryptocurrency data. Our results show that average raw and risk adjusted return differences between cryptocurrencies in the lowest and highest MAX deciles exceed 1.50% per week. These re…
