Advanced Driver Assistance Systems: Multimodal, redundant warnings enhance road safety.
Full text linkAdvanced driver assistance systems or ADAS are designed to assist the driver while at the wheel of a motor vehicle. ADAS constantly monitor certain driving parameters such as the speed of the vehicle. When these parameters exceed safe threshold (e.g., the speed exceeds the limit), warnings are presented to inform the driver that the execution of given driving adjustments is needed in order to avoid likely accidents. Although ADAS may reduce accidents by 20%, if the warnings presented by these systems are poorly-designed, they may even disturb driving and, as a result, slow drivers’ responses when fast, prompt reactions are instead needed. The aim of my doctoral dissertation is to measure the impact produced on driving by a number of warnings and, further, design a warning capable of speeding up drivers’ responses without negatively affect subjective workload. For the execution of the seven experiments (4 in-lab and 3 driving experiments) contained in the dissertation, I considered the redundancy gain as theoretical framework and applied it to driving. I selected four types of warnings: unimodal visual, unimodal auditory, unimodal vibrotactile and
multimodal (auditory + vibrotactile). Results showed that multimodal warnings were capable of reducing braking times even with drivers being distracted by a concurrent cell phone conversation or driving in dense traffic. In addition, no trade-off between braking
times and subjective workload was found. These findings are of the utmost importance for car-manufacturers interested in enhancing the ADAS-driver interaction and, more broadly, for the entire research community working on automated vehicles
Per una lettura del Somnium di Luciano di Samosata
No full textThe article aims to analyze Somnium sive vita Luciani, the declamation delivered by Lucian in his hometown of Samosata in the early 2nd century. In fact, the work provides an introduction to the rhetorician's cultural vocation, revealing to the audience the reason for a choice that turned out to be a successful one. As is clear, the work is a retelling of the ancient fable of Heracles at the crossroads, narrated by Prodicus of Ceos.
The author also suggests that the deep structure of the speech can be identified and that the entire story can be divided into segmentable units linked to a series of character functions. Therefore, applying a formalistic approach to Somnium helps to better understand and appreciate the literary qualities of this text

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
