The learning assessment in e-learning contexts is one of the latest challenges for educational technology researchers. One of the main issues to be addressed is the definition of dimensions that should be used to measure the learning effectiveness. In this perspective, the research work aims at defining the engagement indicators useful to assess the active participation of students in social le...

Summary FQC is software that facilitates quality control of FASTQ files by carrying out a QC protocol using FastQC, parsing results, and aggregating quality metrics into an interactive dashboard designed to richly summarize individual sequencing runs. The dashboard groups samples in dropdowns for navigation among the data sets, utilizes human-readable configuration files to manipulate the pages...

Abstract: Mit der zunehmenden Bedeutung von sozialen Netzwerken und cloudbasierter Systeme nimmt ”Privacy as a Product” eine immer stärkere Bedeutung im Entwicklungsprozess von Web-Applikationen ein. Dies beeinflusst entscheidend die Akzeptanz, Sicherheit und das Vertrauen in neue Produkte. Der Vortrag geht detailliert auf Googles Ansatz zu ”Privacy as a Product” ein: Privacy Technologien versc...

In an ordinary classroom, teachers monitor their students’ emotional reactions while learning, even if only by glancing at their faces while they work. In this way, teachers can gauge the effectiveness of their teaching strategies, determining whether students are bored, frustrated, or anxious. Teachers can see how emotions change over time, perhaps from positive, to challenged, and later trium...

Most Learning Management Systems (LMS) focus on providing rich learning materials to the learners but rarely offer possibilities to monitor and analyze their learning processes. However metacognitive strategies argue that learners can improve their learning performances by monitoring their activities, especially in the context of Project-Based Learning (PBL). Our work consists in designing tool...

Objective We developed geo-targeted social media application program interfaces (APIs) for Twitter and a web-based social media analytics and research testbed (SMART) dashboard to analyze “flu” related tweets. During the 2013-14 flu season, for 10 cities with active surveillance for influenza (ILI), we correlated weekly tweeting rates and visual patterns of flu tweeting rates. To facilitate wid...

The task of the VAST 2013 Mini-Challenge 2 (MC2) was the design of a system targeting the surveillance and the visualization of the current state of the corporate network of Big Enterprises. According to the task given, we focus on displaying three main measures: health, security, and performance of the network. In our approach, we propose a novel visual design, and a new interaction concept an...

Protecting computer and information systems from security attacks is becoming an increasingly important task for system administrators. Honeypots are a technology often used to detect attacks and collect information about techniques and targets (e.g., services, ports, operating systems) of attacks. However, managing a large and complex network of honeypots becomes a challenge given the amount o...
