An ongoing discussion in the field of usable privacy and security debates whether security mechanisms should be visible to end-users during interactions with technology, or hidden away. This paper addresses this question using a mixed-methods approach, focusing on encryption as a mechanism for confidentiality during data transmission on a smartphone application. In study 1, we conducted a qualitative co-creation study with security and Human-Computer Interaction (HCI) experts (N = 9) to create appropriate textual and visual representations of the security mechanism encryption in data transmission. We investigated this question in two contexts: online banking and e-voting. In study 2, we put these ideas to the test by presenting these visual and textual representations to non-expert users in an online vignette experiment (N = 2180). We found a statistically significant and positive effect of the textual representation of encryption on perceived security and understanding, but not on user experience (UX). More complex text describing encryption resulted in higher perceived security and more accurate understanding. The visual representation of encryption had no statistically significant effect on perceived security, UX or understanding. Our study contributes to the larger discussion regarding visible instances of security and their impact on user perceptions. [less ▲]

Premier texte ouvertement politique de George Sand, Fanchette, lettre de Blaise Bonnin à Claude Germain paraît en 1843 dans La Revue indépendante, publication qu’elle a cofondée avec Louis Viardot et Pierre Leroux. Or la brochure a peiné à trouver preneur : la frilosité des imprimeurs locaux, jointe à l’hostilité du ministériel Journal de l’Indre, achèvent de convaincre Sand de fonder un périodique répondant au « besoin de relever l’esprit public en province, et de le mettre sur un pied, non de rivalité, mais d’égalité avec celui de la métropole ». Ce sera L’Éclaireur de l’Indre, journal des départements de l’Indre, du Cher et de la Creuse, lancé en septembre 1844. Envisageant les « petites villes » comme des « antres de corruption, où l’intimidation assure l’impunité au vice et au crime tout autant qu’à Paris le mystère », Sand développe dans les écrits polémiques qu’elle publie dès lors et jusqu’à 1851 un propos proche, sur le plan thématique comme sur le plan rhétorique, de celui de Claude Tillier, pamphlétaire du Nivernais voisin qu’elle cite parfois textuellement. Cofondateur en 1831 de L’Indépendant de Clamecy, périodique républicain, Tillier a rejoint en 1841 les rangs de L’Association, journal de la Nièvre, feuille d’opposition dont il devient bientôt l’un des principaux rédacteurs. Ayant lui aussi à lutter contre la presse ministérielle – dont L’Écho de la Nièvre, organe de la préfecture – et contre l’hostilité affichée des notables locaux, peinant de ce fait à trouver un imprimeur acceptant de publier ses pamphlets, Tillier, républicain revendiqué, n’en défend pas moins dans ce journal comme dans ses pamphlets un propos progressiste où l’idée de justice sociale occupe une place centrale, à l’opposé du libéralisme économique et social débridé qui caractérise la monarchie de Juillet. Le geste polémique de Tillier comme celui de Sand donnent à penser sur la possibilité d’une parole polémique et plus avant sur ses modalités sous le régime de Juillet. Les deux écrivains affrontent, en effet, des réalités différentes. Alors que Tillier, relativement méconnu hors du Nivernais, cherche à faire connaître son œuvre dans la capitale, Sand, écrivaine déjà fameuse, doit pour sa part affronter l’esprit du temps, hostile aux incursions des femmes en terre polémique. Cela conditionne fortement la forme que prennent leurs paroles polémiques respectives, depuis leur support (de l’article de journal à la brochure) jusqu’aux modalités rhétoriques et esthétiques. Aussi cette contribution entend-elle éclairer un aspect méconnu de l’œuvre de Sand et faire redécouvrir celle de Tillier en les étudiant sous divers angles ; on envisagera d’abord les supports de leur propos polémique avant de se pencher sur les thématiques qui leur sont communes. On établira ensuite l’horizon idéologique présidant à ces productions destinées à « relever l’esprit public en province » en y défendant les idées républicaines et socialistes, avant d’étudier les modalités rhétoriques de ces deux œuvres polémiques représentatives de l’esprit du temps.

Based on the classic models developed by Spady and Tinto on the link between social and academic integration and dropout, we propose a refined model to explain dropout intentions – relating to dropout from higher education (HE) and dropout from a specific study programme – that more strongly emphasises individual background characteristics (e.g. gender, social origin, and immigration background). Additionally, we consider students’ satisfaction with the institutional support structures. Using Eurostudent survey data, this conceptual model was tested using structural equation modelling in the international and diverse HE context of Luxembourg. While the fitted model confirmed most of the expected associations of the conventional Spady–Tinto approach, initial study commitment was not linked to social integration (contacts with fellow students). We were able to identify satisfaction with institutional support as a key factor in explaining dropout intention, thus contributing to existing knowledge. In addition, we found that the link between socioeconomic factors and dropout intention from a study programme is not entirely mediated by the Spady–Tinto factors of commitment and integration.

Carbonopolis: Letz bring it down! is a prototype board game that stimulates awareness and encourages exchange on six climate change topics impacting Luxembourg: urban heat islands, extreme weather, quality of life, mobility, housing and the food system. Whilst playing, participants discover and discuss potential sustainable planning initiatives for carbon descent. Aimed at groups of multicultural players, the game was inspired by snakes and ladders and integrates three type of playing cards: (1) multiple-choice questions for knowledge testing (2) planning initiative cards for value-driven policy prioritisation and (3) crisis cards for critically reflecting on current policy impacts. The initial game design was conceived by two academics. Then in the spirit of co-design, as a sustainability action for all, and with the goal of building partnerships beyond the formal curriculum we integrated three Master student assistants and one doctoral student into the process, especially in the graphic design and game evaluation. During play sessions students assumed different roles: players, game leaders and game observers. The game provided an opportunity to raise awareness of local sustainability challenges and nurture future advocates. Additionally, the process provided an interactive and playful method for new co-productive curriculum development and the development of team-based relationships between staff and students. [less ▲]

Policy Coherence for Sustainable Development (PCSD) has promoted sustainability through policy coordination, but to what extent does it respond to the needs of local communities? Scholars of PCSD have acknowledged how it has been considered as an end in itself rather than a means to achieve normative impact. A major limit of PCSD has been its institutionalized nature, as mechanisms for social participation have not been highlighted in implementation strategies. This article addresses this issue. It proposes “pull-push-match” as a methodology for the es-tablishment of participative PCSD. The article, co-authored by a team of researchers and practitioners from Mexico, addresses PCSD in relation to Indigenous communities. [less ▲]

In this study, we present a modified Hartwick rule encompassing the dynamics of pandemic, such as COVID-19. In our setting, the labor productivity gradually improves after the pandemic shock and may even go beyond its pre-pandemic level due to the remote work and digitalization as also suggested by the empirical evidence. We demonstrate that a gradual labor productivity increase helps to conserve natural resources. We provide a theoretical foundation for a“sooner-the-better" strategy to control a pandemic, and we show that policy maker should implement a “whatever it costs” response to ensure that the transmission rate of the virus is below the recovery rate from the very beginning of the pandemic. Otherwise, the economy cannot have a sustained utility. We also analyze the implications of an “uncertain” pandemic on the intertemporal dynamics of natural resource and capital accumulation under the maximin criterion. Another important finding is that there exists a new economic and public health trade-off since a strong prevention policy is shown to decrease capital accumulation. [less ▲]

Very high throughput satellite (VHTS) systems are expected to have a huge increase in traffic demand in the near future. Nevertheless, this increase will not be uniform over the entire service area due to the non-uniform distribution of users and changes in traffic demand during the day. This problem is addressed by using flexible payload architectures, which allow the allocation of payload resources flexibly to meet the traffic demand of each beam, leading to dynamic resource management (DRM) approaches. However, DRM adds significant complexity to VHTS systems, so in this paper we discuss the use of one reinforcement learning (RL) algorithm and two deep reinforcement learning (DRL) algorithms to manage the resources available in flexible payload architectures for DRM. These algorithms are Q-Learning (QL), Deep Q-Learning (DQL) and Double Deep Q-Learning (DDQL) which are compared based on their performance, complexity and added latency. On the other hand, this work demonstrates the superiority a cooperative multiagent (CMA) decentralized distribution has over a single agent (SA). [less ▲]
