The Fourth ACM SIGSPATIAL Workshop on Location-Based Recommendations, Geosocial Networks and Geoadvertising
2021
The amount of publicly available geo-referenced data has seen a dramatic increase over the last years. Many user activities generate data that are annotated with location and contextual information. Moreover, it has become easier to collect and combine rich and diverse location information. In the context of geoadvertising, the use of geosocial data for targeted marketing is receiving significant attention from a wide spectrum of companies and organizations. With the advent of smartphones and online social networks, a multi-billion dollar industry that utilizes geosocial data for advertising and marketing has emerged. Geotagged social-media posts, GPS traces, data from cellular antennas and…
Time-Varying Fundamentals of the Euro–Dollar Exchange Rate
2006
Abstract This study examines changes in the impact of the economic fundamentals on the euro–dollar exchange rate. First, the monetary model is augmented with the equity markets and the model is estimated in its structural form. Second, the time-varying impacts of the long-run fundamentals representing equilibrium in different markets on the euro–dollar exchange rate are examined using Kalman filtering. The time-varying structural model indicated that the relative importance of the different fundamentals was not equal and the impact of the fundamentals was time-dependent.
Impiego di tecniche di misura DIC per lo studio di sistemi di sintesi ortopedici
2009
Nel presente lavoro si esamina la possibilità di impiego di tecniche di correlazione digitale di immagini in configurazione stereoscopica per la valutazione sperimentale in-vitro del campo tridimensionale di spostamento e deformazione generato sottocarico sull’osso trattato con un impianto di sintesi intramidollare. L’inserimento di una rima di frattura praticata sulla diafisi media dell’osso sintetico, ha consentito di studiare il differente comportamento nelle due condizioni limite del decorso clinico a seguito del trattamento chirurgico di impianto. I risultati preliminari riportati nel lavoro dimostrano l’efficacia dell’approccio proposto, che consente di valutare sperimentalmente lo st…

Contagion of Uncertainty: Transmission of Risk from the Cryptocurrency Market to the Foreign Exchange Market
2019
Earlier research documented that cryptocurrencies, including Bitcoin, have experienced dramatic fluctuations in both market capitalization and market share in recent years. Unsurprisingly, Bitcoin returns exhibit higher volatility than traditional G-10 currencies. Our paper extends earlier research and investigates the potential impact of news originating from the Bitcoin market. Confirming earlier studies, we find that Bitcoin exhibits dramatically higher volatility than the dollar factor. Surprisingly, our findings indicate that only hacking incidents that occur in the Bitcoin market result in high levels of co-movement in the risk of both markets the cryptocurrency and the G-10 currency …

At the height of the crisis, the international monetary system is powerless to reduce theinstability of exchange rates, the imbalance of the current account of balance ofpayments, instability of exchange rates and the development of speculation in financialmarkets the and the asymmetry between net exporters countries and net deficits countries.This thesis, which had the merit of opening new tracks in order to understand thecomplex relationships between global imbalances and the actual system, showed thatthese global imbalances are intrinsically linked to the failures of the internationalmonetary structure. To stop the deterioration of global imbalances, we propose that thesystem turns towar…
The euro–dollar exchange rate and equity flows
2009
Abstract I examine equity flows between the US and the euro area and their impact on the euro–dollar exchange rate. I explain equity flows by examining the behavior of an international investor who maintains a minimum variance portfolio. An excess of euro area equity returns over US equity returns generates a flow of equity from the euro area to the US. The equity flow, the purchase of US equities by the euro-area residents, causes appreciation (depreciation) of the dollar (euro), while the purchase of euro area equities by US residents causes appreciation (depreciation) of the euro (dollar).
Confronto tra RM Whole Body, TC/PET e biopsia osteomidollare, nella valutazione dell’interessamento midollare in 104 pazienti con linfoma.
2016
Scopo: Parte della stadiazione dei linfomi prevede la valutazione dell'interessamento del midollo osseo (IMO) mediante biopsia osteo-midollare (BOM) [1]. Tuttavia, secondo le ultime linee guida, la BOM non è più indicata per lo studio dei linfomi di Hodgkin [2]. La TC/PET è la tecnica di imaging standard per la stadiazione dei linfomi FDG-avidi, mentre la TC è indicata nei pazienti con istotipi non FDG-avidi [1]. Molti studi hanno dimostrato affidabilità ed elevata accuratezza diagnostica della Risonanza Magnetica Whole Body (RM-WB) nella stadiazione dei linfomi [3,4]. Lo scopo del nostro studio è stato quello di confrontare RM-WB, TC/PET e BOM, nella valutazione dell’IMO in pazienti con li…
What Do We Know About the Second Moment of Financial Markets?
2021
Recent research shows that the vast majority of scientific studies published in leading finance journals fails scientific replication (Hou, Xue, and Zhang, 2020; Harvey, Liu, and Zhu; 2016). This study argues that p-hacking, publication pressure and the selection bias from leading finance journals are perhaps not the underlying root cause for this issue. We show that standard methodologies often used in finance research are inevitably sample-specific due to the very nature of financial markets. While the consensus of earlier research postulates a rejection of the time-honored Levy hypothesis, our results strongly indicate that the variance of variance does not exist in any of the financial …
