Accident ahead? Difficulties of drivers with and without reading impairment recognising words and pictograms in variable message signs

2017

A timely and accurate acquisition of the information provided by variable message signs (VMS) can be crucial while driving. In the current study, we assess the difficulties of adults with dyslexia acquiring the information shown in VMS and provide evidence to discuss the controversial use of pictograms as potential countermeasures. Twenty-two adults with dyslexia and 22 matched controls completed a simulated driving session. The legibility of 12 VMS was assessed, including six text messages (e.g. "ACCIDENT") and six single pictograms (e.g. the icon for "accident ahead"). On average, participants with dyslexia started reading text messages when they were closer to the VMS. In addition, while…

Permanently online and permanently connected : development and validation of the Online Vigilance Scale

2017

Smartphones and other mobile devices have fundamentally changed patterns of Internet use in everyday life by making online access constantly available. The present paper offers a theoretical explication and empirical assessment of the concept of online vigilance, referring to users' permanent cognitive orientation towards online content and communication as well as their disposition to exploit these options constantly. Based on four studies, a validated and reliable self-report measure of online vigilance was developed. In combination, the results suggest that the Online Vigilance Scale (OVS) shows a stable factor structure in various contexts and user populations and provides future work i…

Impact of olfactory and auditory priming on the attraction towards foods with high energy density

2015

\]\Recent research suggests that non-attentively perceived stimuli may significantly influence consumers' food choices. The main objective of the present study was to determine whether an olfactory prime (a sweet-fatty odour) and a semantic auditory prime (a nutritional prevention message), both presented incidentally, either alone or in combination can influence subsequent food choices. The experiment included 147 participants who were assigned to four different conditions: a control condition, a scented condition, an auditory condition or an auditory-scented condition. All participants remained in the waiting room during15 min while they performed a 'lure' task. For the scented condition,…

A short message service (SMS)-based strategy for enhancing adherence to antipsychotic medication in schizophrenia

2012

Abstract Background The aim of this study was to assess the impact of a short message service (SMS)-based strategy on adherence to antipsychotic treatment. Methods A multicentre, randomised, open-label, controlled, 6-month study with clinically stabilised outpatients with schizophrenia was conducted. The patients assigned to the intervention received daily SMS reminders to take their medication for 3 months. Self-reported medication adherence was determined using the Morisky Green Adherence Questionnaire (MAQ). Secondary outcomes were severity of illness, attitude towards medication, insight into illness and health-related quality of life. Results A total of 254 patients were analysed. A si…

Privacy enhanced mutual authentication in LTE

2013

In this paper we propose a way to enhance the identity privacy in LTE/LTE-Advanced systems. This is achieved while minimizing the impact on the existing E-UTRAN system. This is important since proposals to modify a widely deployed infrastructure must be cost effective, both in terms of design changes and in terms of deployment cost. In our proposal, the user equipment (UE) identifies itself with a dummy identity, consisting only of the mobile nation code and the mobile network code. We use the existing signalling mechanisms in a novel way to request a special encrypted identity information element. This element is protected using identity-based encryption (IBE), with the home network (HPLMN…

Big Data in metagenomics: Apache Spark vs MPI.

2020

The progress of next-generation sequencing has lead to the availability of massive data sets used by a wide range of applications in biology and medicine. This has sparked significant interest in using modern Big Data technologies to process this large amount of information in distributed memory clusters of commodity hardware. Several approaches based on solutions such as Apache Hadoop or Apache Spark, have been proposed. These solutions allow developers to focus on the problem while the need to deal with low level details, such as data distribution schemes or communication patterns among processing nodes, can be ignored. However, performance and scalability are also of high importance when…

BlueIM: Bluetooth Instant Messaging

La desinformación en las redes de mensajería instantánea. Estudio de las fake news en los canales relacionados con la ultraderecha española en Telegr…

2021

espanolOne of the most uncontrolled and wides-pread sources of misinformation are the instant messaging platforms, mainly due to the privacy of the communication spaces created in them. The dissemination of false news on these networks makes it difficult to detect them and thus complicates the task of fact-checking. Both WhatsApp and Tele-gram were used and integrated in the elec-toral campaign of the previous elections in the United States (Journell, 2017; Allcott & Gentzkow, 2017), in the United Kingdom on the occasion of the Brexit (Kucharski 2016), in Brazil (Novomisky, 2018), and recently in the autonomous elections of Andalusia (Spain) (Viejo, 2018). This research takes as a case stud…

Towards Next Generation System Architecture for Emergency Services

2011

European Union has decided that all emergencies can be reported to authorities by European citizens by calling 112 or sending a text message to 112. Distributing warnings and alerts of authorities to citizens currently happens through national TV and radio channels, but telecom networks are also used now in some countries for this purpose. During the last ten years there have been attempts to develop new system architectures for various emergency service provision phases. Some of them are already deployed in special cases, like in ambulance services. Multimedia emergency alert messages can be delivered to citizens over fixed and mobile telecom networks and commercial systems are already in …
