Although Web development was driven by a conceptual repertoire of dematerialisation, of eliminating borders between “Netizens” and ensuring the independence of cyberspace (John Perry Barlow), in the 1990s the accessibility of the Web was largely subject to material challenges associated with infrastructures, equipment, Internet billing and regulation. They were also linked with groups of technicians and communities of practice, the development of ISPs, the acquisition of equipment or the use of cyber cafés. Taking the example of France in the 90s as a starting point, this contribution will shed light on the agencies at work in a bid to demonstrate why digital materiality matters in Web histories.

Computer-aided diagnosis and stratification of COVID-19 based on chest X-ray suffers from weak bias assessment and limited quality-control. Undetected bias induced by inappropriate use of datasets, and improper consideration of confounders prevents the translation of prediction models into clinical practice. By adopting established tools for model evaluation to the task of evaluating datasets, this study provides a systematic appraisal of publicly available COVID-19 chest X-ray datasets, determining their potential use and evaluating potential sources of bias. Only 9 out of more than a hundred identified datasets met at least the criteria for proper assessment of the risk of bias and could be analysed in detail. Remarkably most of the datasets utilised in 201 papers published in peer-reviewed journals, are not among these 9 datasets, thus leading to models with a high risk of bias. This raises concerns about the suitability of such models for clinical use. This systematic review highlights the limited description of datasets employed for modelling and aids researchers to select the most suitable datasets for their task. [less ▲]

In the literature on comparative constitutional law and constitutional theory, monarchies are, if they attract any attention at all, most frequently analyzed from the perspective of the monarch’s political power, after its more or less extensive “neutralization” in the name of the constitutional ideals of Enlightenment. Yet this classic approach, whose focus lies on the State organ’s competencies and the discretion of its royal incumbent, is incomplete as it ignores a second, increasingly important facet of the modernization process of monarchies: To what extent do Royals, including the monarch, have fundamental rights as individuals, as “human beings”? This paper considers in particular the even-more-overlooked issue of their political rights (right to vote, right to stand for election, and the right to use the instruments of direct democracy). The issue, which is a very old one, having being addressed first by Sieyès in his famous 1789 speech on royal veto and by the French Constitution of 1791, is far from being odd or futile. In some jurisdictions, like in Japan (1945), Luxembourg (2004-5), Liechtenstein (2002-3) or in Thailand (2019), it was at the core of quite controversial public debates which, eventually, lead to totally divergent outcomes. Beyond its (relative) importance in practice, it is a key parameter for theoretical purposes: combined with the criteria of the dualistic state organization, it provides a deeper insight into the complex structure of those regimes mixing, in various ways, both monarchical and democratic elements. This article sheds light on this new research field, starting with a broad historical and comparative survey, before presenting a typology in order to tackle the startling diversity of legal solutions.

In this paper, we investigate the multiplexing of grant-based (GB) and grant-free (GF) device transmissions in an uplink heterogeneous network (HetNet), namely GB-GF HetNet, where the devices transmit their information using low-rate short data packets. Specifically, GB devices are granted unique time-slots for their transmissions. In contrast, GF devices can randomly select time-slots to transmit their messages utilizing the GF non-orthogonal multiple access (NOMA), which has emerged as a promising enabler for massive access and reducing access latency. However, random access (RA) in the GF NOMA can cause collisions and severe interference, leading to system performance degradation. To overcome this issue, we propose a multiple access (MA) protocol based on reinforcement learning for effective RA slots allocation. The proposed learning method aims to guarantee that the GF devices do not cause any collisions to the GB devices and the number of GF devices choosing the same time-slot does not exceed a predetermined threshold to reduce the interference. In addition, based on the results of the RA slots allocation using the proposed method, we derive the approximate closed-form expressions of the average decoding error probability (ADEP) for all devices to characterize the system performance. Our results presented in terms of access efficiency (AE), collision probability (CP), and overall ADEP (OADEP), show that our proposed method can ensure a smooth operation of the GB and GF devices within the same network while significantly minimizing the collision and interference among the device transmissions in the GB-GF HetNet.

As 21st century skills have become increasingly important, Collaborative Problem Solving (CPS) is now considered essential in almost all areas of life. Different theoretical frameworks and assessment instruments have emerged for measuring this skill. However, more applied studies on its implementation and evaluation in real-life educational settings are required. In this sense, pre-post experimental designs are essential for identifying new methods for developing collaborative problem-solving skills. To do so, equivalent tests are needed to facilitate consistent score interpretations and reduce the practice effect. In the present study, a Design-Based Research approach is used to design and validate an assessment tool with two equivalent forms based on a framework proposed by the OECD and applied to a collaborative activity. A total of 719 students aged between 10 and 13 years old participated in the different stages of the study. The results show that the proposed instrument effectively measures the problem-solving dimension of collaborative problem-solving skills among students of this age. Moreover, the results from the test were equivalent for both forms and across genders. Finally, there were no significant differences when assessing collaborative problem-solving in human-human groups versus human-agent groups using the proposed instrument. For future work, we recommend including other data sources than just text-based conversations. This would allow us to capture the rich social interactions present in this type of activity. Future work should also consider exploring the extent to which skills could be trained. This could be done in an experimental design assessed using the equivalent forms of the proposed instrument as a pre- and post-test. Doing so would provide a more accurate measure of students’ collaborative skills. [less ▲]
