Objectives: The effects of the COVID-19 outbreak on non-COVID-19-related healthcare need further investigation. Methods: Using the Survey of Health, Ageing and Retirement in Europe’s COVID-19 module (2020) (N = 57,025), country-level data from the European Social Survey (2008) and OECD (2020), and logistic regressions, this study examines predictors of older Europeans’ forgone, postponed, and denied healthcare during the pandemic. Results: Country-level availability of physicians, healthcare systems’ generosity, and beliefs that older persons burden healthcare systems all increased forgone healthcare. Healthcare system generosity increased postponed and denied healthcare. Greater medical resources decreased denied healthcare. Furthermore, missed healthcare varied by individual-level gender (higher rates among women), age, education, and health. Discussion: This study reveals predictors of missed healthcare during the pandemic. To decrease unintended health consequences of a pandemic, both individual-level determinants, such as gender and health, and contextual-level determinants, such as healthcare systems’ characteristics, should be considered in research and practice.

Academic achievement profiles affect students’ further development, i.e., by informing educational and professional choices. However, there is a lack of knowledge on the mechanisms behind the development of academic profiles. For research on cognitive ability profiles, specifically differentiation processes, statistical tools have been developed. In the present article, we transfer these methods for differentiation research to academic achievement data. We examine differentiation depending on students’ general level of achievement and grade level in a large Luxembourgish student sample. Students’ achievements in German, French, and Math were assessed within the Luxembourg school monitoring program. We found more balanced academic profiles with increasing achievement level. We further found more balanced profiles with increasing grade level and a positive interaction effect. [less ▲]

From the Hampster Dance, All your Base are belong to us and the Dancing Baby in the second half of the 1990s to Bernie’s mittens at the US presidential inauguration and the image macros of the Evergreen blocked in the Suez Canal, through Disaster Girl or Distracted Boyfriend to name but a few, memes and Internet phenomena have become in the last twenty years an important part of our digital cultures (Shifman, 2014). After presenting why historicising virality matters (which is the purpose of our Hivi research project supported by the Luxembourg National Research Fund and conducted at the University of Luxembourg, https://hivi.uni.lu), this talk will focus on the challenges related to sources. Historicising online virality requires to first acknowledge how difficult it is to build corpora and develop chronological views in the vast and heterogeneous amount of data lakes and sources available on the live web and in web archives. All these repositories preserve viral content in a very different manner, covering different frames and periods, while the actors who come into play have different size and motivations, from giant platforms (Twitter, YouTube - see Burgess and Green 2018, etc.) to small communities, through heritagisation platform (i.e. Know Your Meme - see Pettis, 2021) and web archives. Therefore, it is necessary to consider the many levels of politics, curation and agencies at stake when studying the history and heritagisation of memes and Internet phenomena and their impact. Finally, temporalities and scales are also challenging, and scalability is key for studying the spreadability of digital contents, notably in a long-term perspective. There is a constant need for balancing between several scales to study circulation and flow (Jenkins, 2009), processes, participation (Milner, 2018) and appropriation, while recontextualizing memes and Internet phenomena in their complex and changing environments (changes of platforms, of participation, of audience, of meaning...).

Analogical transfer, denoting the ability to use an action that solved a given problem in order to successfully handle a seemingly different but functionally similar problem, requires well-developed self-regulation, as it draws on previous knowledge and demands selecting and shifting between relevant features while ignoring irrelevant ones. Thus, analogical transfer involves executive functions (EFs), yet the contribution of specific EFs is unclear, particularly during the development of the capacity before the age of 5. Here, for the first time, we investigated the contribution of world knowledge, working memory and set-shifting in 2.5- to 4.5-year-olds’ (N = 86) capacity to single-event analogical transfer in a simple, non-verbal, tool-use task. Analogical transfer was independent of age but was predicted by a measure of world knowledge and a measure of working memory across the age-span tested. Our results suggest that world knowledge and working memory underscore analogical transfer early in development. [less ▲]

The use of content management systems (CMSes) in public history is a relatively new phenomenon that has greatly enhanced the possibilities of presenting, curating and narrating history online. As CMSes have become increasingly powerful and easier to use, they obviate the need for comparatively costlier custom solutions, both in terms of time and financial investment. Archives, libraries, museums, institutions, scholars and educators are making use of CMSes to showcase collections, accompany exhibitions, tell histories online and to build online communities and networks. This chapter discusses how content management systems support these activities and projects while also delving into more technical aspects. In doing so the chapter focuses on open source systems which can be used by any scholar without incurring licensing fees, and are often supported by large user communities. [less ▲]

Pooled quality controls (QCs) are usually implemented within untargeted methods to improve the quality of datasets by removing features either not detected or not reproducible. However, this approach can be limiting in exposomics studies conducted on groups of exposed and nonexposed subjects, as compounds present at low levels only in exposed subjects can be diluted and thus not detected in the pooled QC. The aim of this work is to develop and apply an untargeted workflow for human biomonitoring in urine samples, implementing a novel separated approach for preparing pooled quality controls. An LC-MS/MS workflow was developed and applied to a case study of smoking and non-smoking subjects. Three different pooled quality controls were prepared: mixing an aliquot from every sample (QC-T), only from non-smokers (QC-NS), and only from smokers (QC-S). The feature tables were filtered using QC-T (T-feature list), QC-S, and QC-NS, separately. The last two feature lists were merged (SNS-feature list). A higher number of features was obtained with the SNS-feature list than the T-feature list, resulting in identification of a higher number of biologically significant compounds. The separated pooled QC strategy implemented can improve the nontargeted human biomonitoring for groups of exposed and nonexposed subjects. [less ▲]

In political terms, European integration and multilateral cooperation enabled Luxembourg to become an equal partner in the decision-making processes and leadership of European organizations. In economic terms, these features gave the country the tools it needed to forge a development model that could underpin the creative growth of its social market economy, while preserving the majority of its vital interests—particularly the steel industry and the financial centre—over the long term. Focusing primarily on the 1970 Werner Report, which served as a blueprint for the European single currency - the euro - the presentation examines a key period in European integration history and one of the major European achievements of Luxembourg and of Pierre Werner (29 December 1913– 24 June 2002), former Prime Minister, Finance Minister and Foreign Minister of Luxembourg, who left his mark on the future of his country and is unanimously recognised as one of the architects of Economic and Monetary Union.

Conciliatory views of disagreement say, roughly, that it’s rational for you to become less confident in your take on an issue in case you find out that an epistemic peer’s take on it is the opposite. Their intuitive appeal notwithstanding, there are well-known worries about the behavior of conciliatory views in scenarios involving higher-order disagreements, which include disagreements over these views themselves and disagreements over the peer status of alleged epistemic peers. This paper does two things. First, it explains how the core idea behind conciliatory views can be expressed in a defeasible logic framework. The result is a formal model that’s particularly useful for thinking about the behavior of conciliatory views in cases involving higher-order disagreements. And second, the paper uses this model to resolve three paradoxes associated with disagreements over epistemic peerhood. [less ▲]

Persuasive online technologies were initially designed and used to gain insights into the online behavior of individuals to personalize advertising campaigns in an effort to influence people and convince them to buy certain products. But recently, these technologies have blurred the lines and morphed into technologies that covertly and gradually manipulate people into attaining a goal that is predetermined by the algorithm and disregards the decision-making rights of the individual. This may lead to people exercising decisions that do not align with their personal values and beliefs, and rob them of their autonomy—an ethical principle, in the absence of which the application of these technologies may be unethical. However, not all technologies that are persuasive are necessarily manipulative which require the careful consideration of a couple of elements to determine whether or not technologies are manipulative and ultimately whether their application is ethical or not. In this article, we analyze the ethical principle of autonomy and unpack the underlying elements of this ethical principle which must be considered to determine whether the application of a technology is ethical or not in the context of it being persuasive or manipulative.

Behavioral software models play a key role in many software engineering tasks; unfortunately, these models either are not available during software development or, if available, quickly become outdated as implementations evolve. Model inference techniques have been proposed as a viable solution to extract finite state models from execution logs. However, existing techniques do not scale well when processing very large logs that can be commonly found in practice. In this paper, we address the scalability problem of inferring the model of a component-based system from large system logs, without requiring any extra information. Our model inference technique, called PRINS, follows a divide-and-conquer approach. The idea is to first infer a model of each system component from the corresponding logs; then, the individual component models are merged together taking into account the flow of events across components, as reflected in the logs. We evaluated PRINS in terms of scalability and accuracy, using nine datasets composed of logs extracted from publicly available benchmarks and a personal computer running desktop business applications. The results show that PRINS can process large logs much faster than a publicly available and well-known state-of-the-art tool, without significantly compromising the accuracy of inferred models.
