Mining Big Data for Tourist Hot Spots: Geographical Patterns of Online Footprints

Understanding the complex, and often unequal, spatiality of tourist demand in urban contexts requires other methodologies, among which the information base available online and in social networks has gained prominence. Innovation supported by Information and Communication Technologies in terms of data access and data exchange has emerged as a complementary supporting tool for the more traditional data collection techniques currently in use, particularly, in urban destinations where there is the need to more (near)real-time monitoring. The capacity to collect and analise massive amounts of data on individual and group behaviour is leading to new data-rich research approaches. This chapter addresses the potential for discovering geographical insights regarding tourists’ spatial patterns within a destination, based on the analysis of geotagged data available from two social networks. ·info:eu-repo/semantics/publishedVersio

Speeded paper-pencil sustained attention and mental speed tests: Can performances be discriminated?

Mental speed (MS) and sustained attention (SA) are theoretically distinct constructs. However, tests of MS are very similar to SA tests that use time pressure as an impeding condition. The performance in such tasks largely relies on the participants’ speed of task processing (i.e., how quickly and correctly one can perform the simple cognitive tasks). The present study examined whether SA and MS are empirically the same or different constructs. To this end, 24 paper-pencil and computerized tests were administered to 199 students. SA turned out to be highly related to MS task classes: substitution and perceptual speed. Furthermore, SA showed a very close relationship with the paper-pencil MS factor. The correlation between SA and computerized speed was considerably lower but still high. In a higher-order general speed factor model, SA had the highest loading on the higher-order factor; the higher-order factor explained 88% of SA variance. It is argued that SA (as operationalized with tests using time pressure as an impeding condition) and MS cannot be differentiated, at the level of broad constructs. Implications for neuropsychological assessment and future research are discussed. Stefan Krumm, Lothar Schmidt-Atzert, Kurt Michalczyk, and Vanessa Danthii

Avoiding Mistakes in Medical High-Tech Treatments and E-Commerce Applications – a Salutary UX-Research Innovation

Medical devices accompany our everyday life and come across in situations of worse condition, in significant moments concerning the health or during routine checkups. To ensure flawless operations and error-free results it is essential to test applications and devices. High risks for patient’s health come with operating errors [33] so that the presented research project, called Professional UX, identifies signals and irritations caused by the interaction with a certain device by analyzing mimic, voice and eye tracking data during user experience tests. Besides, this paper will provide information on typical errors of interactive applications which are based on an empirical lab-based survey and the evaluated results achieved. The pictured proceeding of user experience tests and the following analysis can also be applied to other fields and serves as a support for the optimization of products and systems

Standortbestimmung und Zukunft objektiver Persönlichkeitstests

Dieser Beitrag ist eine Zusammenfassung der Ergebnisse eines Round-Table-Gespräches, welches am 29.09.2005 zur „Standortbestimmung und Zukunft Objektiver Persönlichkeitstests“ in Marburg geführt wurde. Die Diskussion fand unter Teilnahme von Testentwickler(inne)n, Praktikern und Verlagsvertretern in drei thematische Richtungen gegliedert statt: Im ersten Block wurden Definitionen und die Abgrenzungen Objektiver Persönlichkeits-tests von anderen diagnostischen Verfahren diskutiert. Im zweiten Block wurden methodische Probleme, Entwicklungen sowie mögliche zukünftige Ansätze thematisch behandelt. Der drit-te Block sah künftige Strategien für Forschung und Praxis und notwendige Weiterentwicklungen vor. Die Beiträge der Teilnehmerinnen und Teilnehmer zu diesen Themen werden im Folgenden zusammengefasst
