The Data Dilemma: Authors' Intentions and Recognition of Research Data in Educational Technology Research
Educational Technology (EdTec) research is conducted by multiple disciplines, some of which annually meet at the DELFI conference. Due to the heterogeneity of involved researchers and communities, it is our goal to identify categories of research data overseen in the context of EdTec research. Therefore, we analyze the author's perspective provided via EasyChair where authors specified whether they had research data to share. We compared this information with an analysis of the submitted articl…

Another of my forays into AI ethics is just out! This time the focus is on the ethics (or lack thereof) of Reinforcement Learning Feedback (RLF) techniques aimed at increasing the 'alignment' of LLMs.
The paper is fruit of the joint work of a great team of collaborators, among whom @… and @…

Helpful, harmless, honest? Sociotechnical limits of AI alignment and safety through Reinforcement Learning from Human Feedback - Ethics and Information Technology
This paper critically evaluates the attempts to align Artificial Intelligence (AI) systems, especially Large Language Models (LLMs), with human values and intentions through Reinforcement Learning from Feedback methods, involving either human feedback (RLHF) or AI feedback (RLAIF). Specifically, we show the shortcomings of the broadly pursued alignment goals of honesty, harmlessness, and helpfulness. Through a multidisciplinary sociotechnical critique, we examine both the theoretical underpinni…

A 3D Mobile Crowdsensing Framework for Sustainable Urban Digital Twins
In this article, we propose a 3D mobile crowdsensing (3D-MCS) framework aimed at sustainable urban digital twins (UDTs). The framework comprises four key mechanisms: (1) the 3D-MCS mechanism, consisting of active and passive models; (2) the Geohash-based spatial information management mechanism; (3) the dynamic point cloud integration mechanism for UDTs; and (4) the web-based real-time visualizer for 3D-MCS and UDTs. The active sensing model features a gamified 3D-MCS approach, where participan…

Statistical Channel Based Low-Complexity Rotation and Position Optimization for 6D Movable Antennas Enabled Wireless Communication
Six-dimensional movable antenna (6DMA) is a promising technology to fully exploit spatial variation in wireless channels by allowing flexible adjustment of three-dimensional (3D) positions and rotations of antennas at the transceiver. In this paper, we investigate the practical low-complexity design of 6DMA-enabled communication systems, including transmission protocol, statistical channel information (SCI) acquisition, and joint position and rotation optimization of 6DMA surfaces based on the …

The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative potential for physically secure communications, resilience of Global Navigation Satellite Systems (GNSS) and fundamental physics. However, so far these capabilities remain confined to isolated testbeds, with quantum and T&F signals accessible, for example in Germany, to only a few institutions. We propose the QTF-Back…

Emerging applications of neurotechnology and their implications for EU governance #BCI

Emerging applications of neurotechnology and their implications for EU governance
This report sums up recent developments in neurotechnology, that is, technology that can read and modify activity from the central nervous system. Some devices record information from the brain, and others deliver stimulation to the brain (and some do both). These technologies are rapidly advancing and are likely to have a profound impact on various aspects of society. In the near future, neurotechnology is set to revolutionise the way we approach a range of policy areas, from healthcare, educa…

Measuring likelihood in cybersecurity
In cybersecurity risk is commonly measured by impact and probability, the former is objectively measured based on the consequences from the use of technology to obtain business gains, or by achieving business objectives. The latter has been measured, in sectors such as financial or insurance, based on historical data because there is vast information, and many other fields have applied the same approach. Although in cybersecurity, as a new discipline, there is not always historical data to supp…

Test of LGAD as Potential Next-Generation μSR Spectrometer Detectors
Muon Spin Rotation/Relaxation/Resonance ($μ$SR) is a versatile and powerful non-destructive technology for investigating the magnetic properties of materials at the microscopic level. The $μ$SR technique typically utilizes fully spin polarized beams of positive muons generated at particle accelerator facilities and measures the evolution of the muon spin polarization inside a sample to extract information about the local magnetic environment in materials. With the development of accelerator t…

To improve the data quality and reliability of the proposed IRS as a stable, secure, and resilient decision support system, blockchain technology is integrated into the baseline architecture. The smart contract is prototyped to demonstrate the information exchange mechanism under a BLC network environment. The BLC-IRS …

“A cautionary history: In 1999, the US coal industry claimed that information technology would need half the nation’s electricity by 2020, so a strong economy required far more coal-fired power stations. Such claims were spectacularly wrong but widely believed, even by top officials. Hundreds of unneeded power plants were built, hurting investors. Despite that costly lesson, similar dynamics are now unfolding again.”
