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…

Cryptocurrency Perception Within Countries: A Comparative Analysis

2020

Purpose: The paper explores the differences between countries concerning perception and use of traditional and virtual money. We try to answer the question who uses virtual money for investment and building assets and who uses it just for Internet payments. The background of the analysis are significant changes that have taken place in the virtual money market in recent years in relation to changes in the global financial market. Design/methodology/approach: A pilot study was conducted in Poland, the Russian Federation, and China, which is supposed to be an introduction to the bigger and wider survey. It was conducted within December 2019 and January 2020 with 81 surveyed persons. These wer…

The Mathematical Table of the Palazzina Cinese in Palermo. Animation and Virtual Reality Techniques for an Edutainment Project

2023

The Palazzina Cinese of Palermo was built on a project by Venanzio Marvuglia in 1799 on behalf of Ferdinand IV of Borbone, when the royal family, fleeing from Naples following the establishment of the Parthenopean Republic, moved to Sicily. The building, known as “Chinese” due to its style, is full of particular architectural and decorative solutions. An element of particular interest is theMathematical Table, designed to avoid any contact between the living room and the kitchen below, isolating it from smells and servants. Thanks to a complex system of winches and pulleys, in fact, the dishes could be served by letting the central portion of the table and small circular areas fall into the…

Innovative techniques for survey and communication of cultural heritage

2008

This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies. The case of study is the polychrome wooden ceiling in the “Magna” Hall of “Palazzo Steri”. The “Steri”, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector’s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of the ancient wood ceiling and achieve, int…

BIM e beni architettonici: verso una metodologia operativa per la conoscenza e la gestione del patrimonio culturale. BIM and architectural heritage: …

2016

The study aims to answer the growing need for virtuously organize informational apparatuses related to Cultural Heritage. We propose a methodology that integrates multidisciplinary processes of interaction with information aimed at survey, documentation, management, knowledge and enhancement of historic artifacts. It is needed to review and update the procedure of instrumental data acquisition, standardization and structuring of the acquired data in a three-dimensional semantic model as well as the subsequent representability and accessibility of the model and the related database. If the use of Building Information Modeling has in recent years seen a consolidation in the procedures and the…
