The Fall of Monuments: a Public History Monuments have, for a few years now, been hitting the headlines all over the world. Public debates do not focus so much on the erection of new monuments as they do on acts of vandalism, removal, and destruction. If destructions of monuments are not new – for example during the French Revolution – their multiple examples all around the world (United States, England, Australia, Spain, Argentina, South Africa for instance) raise questions about their origins, meanings, and consequences. In my presentation, I propose to understand those synchronous destructions and removals through the angle of public history. Developed as a process to include publics into its production, interpretation, and communication, public history helps to better understand the issues at stake in destroying monuments. In the words of Ludmilla Jordanova, the past is more than ever considered as a public property subject to many different interpretations. Remembering and interpreting the past has become more democratic, more participatory, more diverse but has also shacked power relations. New participatory practices have impacted how we memorialize and interpret the past at official levels. Questions such as who owns the past and who can decide what historical events, actors can be remembered through monuments are being reconsidered. In this reinvention of our relations to monuments – and indirectly to the past – I propose to reconsider the role of historians. I argue that more than simply interpreting the past, historians can help communities deciding what to do with (unwanted) monuments [less ▲]

This paper studies the size and location of small urban green areas across city spaces. Small urban green areas offer amenities that affect residential choices, land consumption and land rent. This paper discusses the land use and locations of those areas and the resulting residential space allocation. It is shown that the land share dedicated to small urban green areas results from the trade-off between land value and population density and is a single peaked function of the distance to the city center. This result is confirmed by the empirical study of urban structures in the 305 largest EU cities using GIS data. This spatial pattern is shown to be robust to many measures of urban land uses.

Investigating the role of individual differences in the hypoalgesic response to a virtual reality game: An exploratory analysis

Introduction: Virtual reality (VR) has been shown to be a powerful method of redirecting attention away from pain and is increasingly used in clinical settings as a therapeutic tool for pain treatment. Yet, little is known about the underlying factors that modulate the size of the hypoalgesic response to a VR game, such as cognitive load and inter-individual differences in self-reported pain-related cognitions, emotion regulation habits, gaming skills, and executive functions. Methods: 90 healthy participants played two versions of the VR game 'Subnautica', differing in cognitive load (low load vs. high load). In the low load condition, participants navigated along a predefined route. In the high load condition, participants additionally memorized a series of single digits presented along the route. Pain heat thresholds as well as psychophysiological measures (ECG, EDA) were recorded during a passive control condition (in VR) prior to, as well as during, the two interactive sessions. In addition, participants completed several psychological questionnaires and different executive functioning tasks prior to the VR sessions. Results: Pain thresholds were significantly higher in the two interactive VR sessions when compared to the passive control condition, whereas the cognitive load of the game had no effect on pain thresholds. Individual differences in pain-related cognitions, prepotent response inhibition abilities and the level of emotional awareness reported by female participants, but not the level of gaming skills, influenced the size of the hypoalgesic effect. Discussion: In line with a growing body of studies, we observed a robust hypoalgesic response to playing a VR game, highlighting once more the potential of VR as a tool for pain reduction. Importantly, the hypoalgesic effect was not dependent on the participants’ level of gaming skills or the cognitive load of the game, suggesting that the sensory properties of the VR game were sufficient to change the processing of pain.

COVID-Kids Le projet COVID-Kids vise à explorer le bien-être des enfants et leurs expériences quotidiennes pendant la pandémie de Coronavirus entre mai et juillet 2020. Film 1 Écoutez les enfants et les adolescents Ce premier épisode présente le projet COVID-Kids ainsi que quelques constations clés. Il montre quatre enfants ayant vécu des expériences différentes durant la pandémie. Tandis que certains ont trouvé stressant ou ennuyeux le fait d'être à la maison, d'autres ont apprécié le temps passé en famille. L'objectif du projet COVID-Kids est d'explorer le bien-être des enfants et leurs expériences quotidiennes pendant la pandémie de Coronavirus entre mai et juillet 2020. Film 2 La peur de tomber malade Quatre enfants parlent de la peur de tomber malade. Alors que deux n'avaient pas peur, un enfant craignait qu'un membre de sa famille tombe malade et un autre s'est fait gronder par des adultes parce qu'ils pensaient qu'il s'était trop rapproché. D’autres résultats du projet sont présentés. L'objectif du projet COVID-Kids est d'explorer le bien-être des enfants et leurs expériences quotidiennes pendant la pandémie de Coronavirus entre mai et juillet 2020. Film 3 Expériences avec le travail scolaire à la maison Ce dernier film présente quelques prédicteurs du bien-être des enfants liés au travail scolaire pendant la pandémie : la quantité, la difficulté et le contenu des devoirs. Les expériences des enfants ont varié et tout le monde ne s'en est pas bien sorti. L'objectif du projet COVID-Kids est d'explorer le bien-être des enfants et leurs expériences quotidiennes pendant la pandémie de Coronavirus entre mai et juillet 2020. [less ▲]

Unmanned Aerial Vehicles (UAVs) have quickly become one of the promising Internet-of-Things (IoT) devices for smart cities. Thanks to their mobility, agility, and onboard sensors'customizability, UAVs have already demonstrated immense potential for numerous commercial applications. The UAVs expansion will come at the price of a dense, high-speed and dynamic traffic prone to UAVs going rogue or deployed with malicious intent. Counter UAV systems (C-UAS) are thus required to ensure their operations are safe. Existing C-UAS, which for the majority come from the military domain, lack scalability or induce collateral damages. This paper proposes a C-UAS able to intercept and escort intruders. It relies on an autonomous defense UAV swarm, capable of self-organizing their defense formation and to intercept the malicious UAV. This fully localized and GPS-free approach follows a modular design regarding the defense phases and it uses a newly developed balanced clustering to realize the intercept- and capture-formation. The resulting networked defense UAV swarm is resilient to communication losses. Finally, a prototype UAV simulator has been implemented. Through extensive simulations, we demonstrate the feasibility and performance of our approach. [less ▲]

In this study, a one-dimensional generic model capable of being integrated with reactor scale models is proposed for a single pellet through solving the transient diferential conservation equations. Predicted results comparison with the experimental data showed close agreement. In addition, the model was used to investigate the relevance of physical characteristics of pellet, reacting gas composition, difusion factors, and prevailing regime. It was found that the pure magnetite pellet could achieve a temperature rise of about 245 K at oxygen concentration of 40 vol.%, whereas the maximum temperature diference inside the pellet was approximately 24 K. Moreover, increasing pellet size, the maximum attainable temperature reached a peak and then leveled out. Furthermore, by decreasing the pore diameter, the pellet size with peak temperature shifted to the smaller pellet sizes. Analyzing the numerical results also showed that for the small pellet sizes, shortening the difusion path leads to the spreading of the reaction interface. The modeling methodology herein can be applied to any particulate processes and is not limited to the aforementioned case. [less ▲]
