Make It or Break It: The Break-Through Rule as a Break-Through for the European Takeover Directive?
2003
The break-through concept is the most recent idea to break the deadlock with respect to EU takeover legislation. As devised by the High-Level Group of Company Law Experts, chaired by the Dutch Jaap Winter, the break-through concept would do away with two of the most important types of impediments to takeovers within EU member states. The first part of the paper explores the break-through concept in some detail, particularly with respect to its premises, its two guiding principles - exclusive shareholder decisionmaking and proportionality, - and the justifications given by the Group for the proposed interventionist rules. The second part of the paper is dedicated to an analysis of the econom…
IT-Sicherheit in medizinischen Netzen - aktuelle Probleme und Lösungsansätze
2000
Designers and users of medical networks have to face strong requirements for data protection and security. Professional discretion and data protection laws allow the transfer of or access to patient data only in a therapeutic context. These data should also be protected from the network provider. Patients should be safe from any harm by faulty data or buggy procedures. On the other hand the security of the most used software products gets worse and worse. The use of the internet endangers more and more the integrity of the user's computer. The security requirements can be met only through strict care in planning, building, and configuring the infrastructure. Some concrete recommendations an…
Comparison of Attention Behaviour Across User Sets through Automatic Identification of Common Areas of Interest
2020
Eye tracking is used to analyze and compare user behaviour within numerous domains, but long duration eye tracking experiments across multiple users generate millions of eye gaze samples, making th ...
Patterns and determinants of adherence to resistance and endurance training during cancer treatment in the Phys-Can RCT.
2022
Abstract Background Knowledge regarding adherence is necessary to improve the specificity of exercise interventions during cancer treatment. We aimed to determine adherence to resistance and endurance training interventions in parallel; identify subgroups with similar adherence characteristics; and examine determinants of these subgroups. Methods In the Phys-Can randomised controlled trial, participants (n = 577, 81% women, mean(SD) age 59(12) years, and 50% with BMI ≥ 25 kg/m2) starting (neo-) adjuvant treatment for breast, colorectal or prostate cancer were randomized to 6-month of high (HI) or low-to-moderate intensity (LMI) supervised, group-based resistance training and individual home…
Navigating uncharted waters: Designing business models for virtual and augmented reality companies in the medical industry
2021
Abstract New technologies are at the heart of industry transformation. Virtual and augmented reality companies provide fundamentally new ways of communication, treatment, education, and specialist training within the medical industry. However, business models for new ventures that target the medical industry have received scant attention within academic research. Using a multiple case study approach, we analyze how virtual and augmented reality firms create value for their customers in the medical industry. In all, we have studied eight companies that offer different types of solutions for their target segments. The results of the analysis are four design elements consisting of twelve posit…
Combining content extraction heuristics
2008
The main text content of an HTML document on the WWW is typically surrounded by additional contents, such as navigation menus, advertisements, link lists or design elements. Content Extraction (CE) is the task to identify and extract the main content. Ongoing research has spawned several CE heuristics of different quality. However, so far only the Crunch framework combines several heuristics to improve its overall CE performance. Since Crunch, though, many new algorithms have been formulated. The CombinE system is designed to test, evaluate and optimise combinations of CE heuristics. Its aim is to develop CE systems which yield better and more reliable extracts of the main content of a web …
Effects of Scientific Information Format on the Comprehension Self-Monitoring Processes: Question Generation // Efectos del formato en que se present…
2013
Generating questions is a regulatory action associated with self-monitoring processes in comprehension tasks: subjects can ask information seeking questions to solve comprehension obstacles. A sequence of two related experiments were conducted to trigger, classify and analyse questions asked under different conditions: reading a text about experimental scientific devices operating, watching these devices in a DVD and manipulating them in the LAB. Students’ information seeking questions were classified using a simple taxonomy. Taking into account the multimedia learning principles, the advantages of realistic animations for understanding time-depending processes and the effect of the procedu…
Pseudo-haptic Controls for Mid-air Finger-based Menu Interaction
2019
Virtual Reality (VR) is more accessible than ever these days. While topics like performance, motion sickness and presence are well investigated, basic topics as VR User Interfaces (UIs) for menu control are lagging far behind. A major issue is the absence of haptic feedback and naturalness, especially when considering mid-air finger-based interaction in VR, when "grabbable" controllers are not available. In this work, we present and compare the following two visual approaches to mid-air finger-based menu control in VR environments: a planar UI similar to common 2D desktop UIs, and a pseudo-haptic UI based on physical metaphors. The results show that the pseudo-haptic UI performs better in t…
The human-computer connection: An overview of brain-computer interfaces
2018
This article introduces the field of brain-computer interfaces (BCI), which allows the control of devices without the generation of any active motor output but directly from the decoding of the user’s brain signals. Here we review the current state of the art in the BCI field, discussing the main components of such an interface and illustrating ongoing research questions and prototypes for controlling a large variety of devices, from virtual keyboards for communication to robotics systems to replace lost motor functions and even clinical interventions for motor rehabilitation after a stroke. The article concludes with some insights into the future of BCI.
Three Dimensions of Dialogicity in Dialogic Argumentation
2019
Three dimensions of dialogicity are emphasised in the literature: dialogic teacher talk, students' dialogic moves and organising for dialogic teaching. In this article, we examine these dimensions and the interplay between them in supporting dialogic argumentation in the context of whole-class discussions in mathematics and physics. Three seemingly different seventh-grade lessons were selected for further analysis from the database of a research project on dialogic argumentation. In this paper, we focus on whole-class discussions after a group assignment. The lessons were video recorded with multiple cameras and transcribed. We characterised dialogic features of teacher talk, more general t…
