The authors examined the hypothesis that psychosocial identity development is related to need for cognition (NFC), a social–cognitive individual-difference variable defined as the desire to engage in effortful thinking (J. T. Cacioppo, R. E. Petty, J. Feinstein, & W. Jarvis, 1996). They administered 2 measures of psychosocial identity—a scale from the Extended Objective Measure of Ego Identity ...

— In this paper a new location indoor system is presented, which shows the position and orientation of the user in closed environments, as well as the optimal route to his destination through location tags. This system is called Labelee, and it makes easier the interaction between users and devices through QR code scanning or by NFC tag reading, because this technology is increasingly common in...

The free vibration of a fluid/structure system consisting of a cylindrical blockage submerged in a liquid enclosed by a cylindrical shell is investigated for the purpose of pipe line transportation monitoring. The wavenumbers are obtained and the reflection and transmission characteristics of these waves at the blockage interfaces are investigated theoretically. Reflection and transmission rati...

With the increasing popularity of Near field communication (NFC) in consumer-off-the-shelf devices, more and more applications are taking advantage of the technology in innovative ways. Unfortunately, with the rise of NFC applications, there emerges a variety of vulnerabilities that could leave an unwitting user vulnerable to a data breach. One such potentially devastating attack is mobile pick...

This paper introduces a peripheral device that supports communication especially in terms of expressive power in mobile environments. As people can speak and hear while doing something else without losing concentration very much, sound has been chosen as a communicating medium not to prevent the daily use of the device. Referring to the conditions recognized by an electronic sensory system, the...

Malware targeting mobile phones is being studied with increasing interest by the research community. While such attention has previously focused on viruses and worms, many of which use near-field communications in order to propagate, none have investigated whether more complex malware such as botnets can effectively operate in this environment. In this paper, we investigate the challenges of co...

Die Wartung von Notfallsystemen bei Gebäuden wie z.B. Sprinkleranlagen kann im Brandfall überlebenswichtig sein; bisher dominieren allerdings kostenund zeitintensive Papier-basierte Lösungen. Dieser Beitrag beschreibt im Rahmen des Facility Managements bzw. der Gebäudeinstandhaltung einen Demonstrator auf der Basis von NFC-Mobiltelefonen. Das System bietet eine Echtzeit-Dokumentation und damit ...

The protocol by which “contactless” (NFC) credit cards operate is insecure. Previous work has done much to protect this protocol from malicious third parties, e.g. eavesdroppers, credit card skimmers, etc. However, most of these defenses rely on the retailers being honest, and on their Points of Sale following the credit card protocol faithfully. In this paper, we extend the threat model to inc...

A fundamental objective of human-computer interaction research is to make systems that are seamlessly integrated into daily life activities. Hence, the challenge is not only to make information available to people at any time, at any place, and in any form, but specifically to say the right thing at the right time in the right way. On the other hand, the proliferation of sensor technology is fa...

Several IS studies have investigated the concept of flow. Among the many antecedent factors leading to flow experience, an individual’s cognitive factors require further exploration, because flow was reported in previous studies more than three times as often in work as in leisure and most frequently associated with online cognitive information processing activities. Following Finneran and Zhan...
