Location-aware applications require a geographic location service of Internet hosts. We focus on a measurement-based service for the geographic location of Internet hosts. Host locations are inferred by comparing delay patterns of geographically distributed landmarks, which are hosts with a known geographic location, with the delay pattern of the target host to be located. Results show a signif...

More and more we interact with other people across varying amounts of geographical distance. What shapes our categorization of a fixed amount of such distance as near or far? Building upon and expanding prior work on the association between spatial distance perception and reachability, we argue that people judge a given geographical distance as subjectively smaller when they can exert control a...

Understanding how much two individuals are alike in their interests (i.e., interest similarity) has become virtually essential for many applications and services in Online Social Networks (OSNs). Since users do not always explicitly elaborate their interests in OSNs like Facebook, how to determine users’ interest similarity without fully knowing their interests is a practical problem. In this p...

The network management problem is a very practical, yet complex and theoretically interesting problem. Understanding the problem requires exposure to the issues faced in managing a complex system. Given the lack of theoretical models for large-scale networks, we seek to understand the issues through data analysis. Toward this end, we are using the Access Grid (AG) as a testbed for network manag...

This paper is aimed at presenting SSRI online: an e-learning initiative started at the University of Milan (Italy) for the academic year 2004/05. The initiative consisted in offering an already existing three-years academic degree course (“laurea in Sicurezza dei Sistemi e delle Reti Informatiche SSRI”: a post-bachelor course on security of computer systems and networks) not only in the “tradit...

This dissertation is the result of my own work and includes nothing which is the outcome of work done in collaboration except where specifically indicated in the text. This dissertation does not exceed the regulation length of 60 000 words, including tables and footnotes. Summary Online social networking services entice millions of users to spend hours every day interacting with each other. At ...

This paper analyses the determinants of newly built dwelling prices in Serbia in a panel of 24 cities over the period 2011-2014. Results suggest that dwelling prices primarily tend to rise with population growth and real total net wages as a proxy of household incomes, while declines in effective interest rate on housing loans are associated with higher dwelling prices. Additional explanatory v...

Background: In Global Software Development (GSD) the lack of face-to-face communication is a major challenge and effective computer-mediated practices are necessary to mitigate the effect of physical distance. Communication through Social Software (SoSo) supports team coordination, helping to deal with geographical distance; however, in Software Engineering literature, there is a lack of suitab...

Salivary biomarkers have been increasingly popular in stress research as saliva is easily produced and collection is non-invasive and not limited by geographical distance or lack of infrastructure. Several salivary biomarkers have been utilized in stress research, for instance, salivary cortisol, salivary amylase and salivary immunoglobulin A. Despite being sensitive to changes in fatigue, they...
