Investigating metaphors of musical involvement : Immersion, flow, interaction and incorporation
2018
The concept of immersion, despite being relatively unknown within music research, presents a potentially productive way for understanding the well acknowledged phenomenon of "being drawn into music". This paper 1) discusses immersion as a metaphor for conceptualizing musical involvement by drawing on the research into video games and virtual reality and 2) aims to clarify the metaphor of immersion by utilizing the concept of image schema to analyze it in relation to alternative metaphors of flow, interaction and incorporation. The theoretical stance of the paper is based on the paradigm of enactive cognitive sciences, which stresses the bodily, constructive and interactive nature of experie…
Exploring the discursive construction of subgroups in global virtual teams
2021
The global teams literature has increasingly documented challenges due to demographic faultlines. While this literature tends to assume that faultlines are fixed and produce negative outcomes for teams, organizational communication scholars have long regarded team processes as dynamic and fluid. Drawing on a CCO perspective, we offer a re-conceptualization of subgroups as dynamic and discursively constructed. This study draws on an in-depth, longitudinal analysis of two global virtual teams to examine the discursive construction of subgroups and the role they play in team dynamics. Through a multi-method analysis of a corpus of 839 emails and 16 interviews with members of two global project…
International Transport Corridors Functioning Efficiency in the Digital Economy Conditions
2019
The problem that is taken under consideration in the following article concerns the implementation, use and effectiveness of virtual work in the supply chain in e-economy. Any solution concern employee mobility or the use of mobile technology are due to growing market competition and constant search for new solutions that may enable the companies in the supply chain to be more efficient than the competition. In the supply chain the E-business creates for the companies new challenges they have to face. One of the possibilities to improve your business in the supply chain is to use virtual work. The new challenge facing the e-economy needs to be met. The aim of the article is to refer the vir…
A Reconfigurable Immersive Workbench and Wall-System for Designing and Training in 3D Environments
2007
Virtual and Augmented Reality have been widely used in many scientific fields for the last two decades in order to visualize complex data and information. Although both techniques are oriented to show users complex 3D environments by means of an intuitive and easy mechanism, they use to become useless to manipulate the information in an intuitive and realistic way. In this paper, we present SOROLLA, a new concept of workbench designed for virtual and augmented reality purposes and specially oriented to the fields of teleeducation and engineering. Unlike other proposals, SOROLLA not only allows an easy utilization and configuration, but also shows a cost-effective immersive visualization sys…
Virtual element method for computational homogenization of composite and heterogeneous materials
2020
Abstract In this study, a two-dimensional multi-region framework, based on the use of the Virtual Element Method (VEM), is developed for computational materials homogenization and applied to different classes of widely employed heterogeneous materials. The VEM has recently emerged as a powerful generalisation of the Finite Element Method capable of dealing with very general polygonal mesh elements, including non-convex or highly distorted elements. Such features are appealing for the treatment of problems whose analysis domains present complex or statistical morphological features, which would generally require careful and time-consuming mesh/data preparation and regularization. In this wor…
The economic impact of water taxes: a computable general equilibrium analysis with an international data set
2008
Water is scarce in many countries. One instrument for improving the allocation of a scarce resource is (efficient) pricing or taxation. However, water is implicitly traded on international markets, particularly through food and textiles, so that the impacts of water taxes cannot be studied in isolation, but require an analysis of international trade implications. We include water as a production factor in a multi-region, multi-sector computable general equilibrium model (GTAP), to assess a series of water tax policies. We find that water taxes reduce water use and lead to shifts in production, consumption and international trade patterns. Countries that do not levy water taxes are nonethele…
The Economic Impact of Restricted Water Supply: a Computable General Equilibrium Analysis
2007
Water problems are typically studied at the level of the river catchment. About 70% of all water is used for agriculture, and agricultural products are traded internationally. A full understanding of water use is impossible without understanding the international market for food and related products, such as textiles. The water embedded in commodities is called virtual water. Based on a general equilibrium model, we offer a method for investigating the role of water resources and water scarcity in the context of international trade. We run five alternative scenarios, analyzing the effects of water scarcity due to reduced availability of groundwater. This can be a consequence of physical con…
A grid representation for distributed virtual environments
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to new grid computing applications where concepts such as sharing and high scalability are extremely exploited. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective DVE system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the arbiters (servers) in the system. As an alternative to the ad-hoc heuristic proposed in the l…

Slacking with the Bot: Programmable Social Bot in Virtual Team Interaction
2021
Nonhuman communicators are challenging the prevailing conceptualizations of technology-mediated team communication. Slackbot is a social bot that can be configured to respond to trigger words and, thus, take part in discussions on the platform. A set of 84 bot-related communication episodes were identified from a journalistic team's Slack messages (N=45,940) and analyzed utilizing both qualitative content analysis and interaction process analysis (IPA). This integrated mixed-methods analysis revealed novel insights into the micro-level dynamics of human-machine communication in organizational teams. In response to Slackbot's greetings, acclamations, work-related messages, and relational mes…
