No full textPut it Back! Archived Memes in Context
No full textpeer reviewedMemes constitute a significant aspect of online digital cultures (see Shifman, 2014; Milner, 2018; Denisova, 2016). Their role in reactions to events like the Ukrainian war highlights their broad influence. However, preserving memes, especially in their original context, proves challenging (Pailler & Schafer, 2022). Initiatives like SUCHO's Meme Wall and the one by the Library of Congress (which archived Know Your Meme but also Meme generator, when creating a particular collection in 2017 “Remix, Slang and Memes: A New Collection Documents Web Culture”) reflect attempts at preserving these cultural artifacts. Furthermore, institutional web archives, as exemplified by projects I led like Hivi (A history of online virality) and Buzz-F in collaboration with the BnF Datalab, have significant content related to memes and viral online phenomena such as the Harlem Shake. Nevertheless, the process of archiving memes remains underdeveloped, resulting also in challenges related to retrievability, searchability, and contextualization.
This presentation delves first into the unique challenges posed by memes concerning contextualization. It explores their circulation across platforms, notably on social media networks, their diverse and ephemeral nature, and the cognitive context intricacies tied to content and usage. Memes can for example vary drastically in meaning based on where they appear – be it a tweet, a post within an activist Facebook group, or other contexts. Understanding these multilayered intricacies is vital for comprehending the broader significance of memes and for developing suitable archiving processes.
Following a brief presentation of the various contextual layers involved into meme analysis, we will delve into the extent to which meme archiving addresses – or could address – these diverse dimensions. It becomes crucial to identify elements that must be preserved to facilitate proper contextualization and potential new approaches to these challenges. One proposal involves for example creating shared ontologies to enrich metadata. Additionally, the idea of specialized meme collections within archives could be explored.
This presentation draws upon the experience gained from two research projects, Hivi and Buzz-F, with the aim of initiating a discussion on context preservation and the challenges posed by ephemeral online phenomena such as memes. It offers insights relevant to the Research & Access theme, touching upon topics such as Unrealized business and technical requirements for web archives research; Creating & providing researchers with datasets from web archives collections; Collaborations between researchers and web archivists.R-AGR-3937 - C20/SC/14758148/HIVI - SCHAFER Valéri
The effect of crystal orientation on the wetting behaviour of silicate melts on the surfaces of spinel peridotite minerals
No full textThe effect of crystal anisotropy on wetting angles of equilibrium silicate melts on crystal faces of spinet, diopside. enstatite and olivine has been determined experimentally by the sessile melt drop technique. The anisotropy (A) over tilde gamma(SL), of solid-liquid interfacial energies (gamma(SL) (max')-gamma(SL) (min)) can be related to the wetting angles, psi, by (A) over tilde gamma(SL) proportional to \cos psi (max) - cos psi (min)\ = Pw ((A) over tilde gamma(SL)). Normalising to the smallest wetting angle gives values of P-w for diopside = 0.0728, olivine = 0.0574, orthopyroxene=0.01521, and spinel=0.0075. Crystal anisotropy influences grain-scale morphology of small-degree partial melts. permeability and the melt connectivity threshold, phi(c). Results show that, at sufficient melt fractions. diopside should increase permeability in a peridotitic matrix, whereas enstatite should lower it. Despite its low anisotropy, spinet contributes positively to permeability and phi(c) because of its high surface energies. These results suggest that harzburgitic mineral matrices typical of the suberatonic mantle should impede the movement of low-degree partial melts, whereas melts should flow more easily through spinet lherzolites

The gravitational field of a radiating and contracting spherically-symmetric body with heat flow
No full textA model of a highly idealized spherically symmetric object radiating away its mass with constant luminosity is presented. The body starts at t = -infinity with both infinite mass and radius and contracts to a point at t = 0 without forming an event horizon. Its material particles are moving non-geodesically and shearfree while transporting heat to the surface. Unlike in some radiating star models of a similar type, all physically required conditions are satisfied in this model

Improving the quality of national organic seed databases to increase the use of organic seed and propagation materials in Europe
No full textThe purpose of the European national organic seed databases is to list the varieties for which organically produced seeds and vegetative propagation material is available on the market. The correct functioning of the databases can facilitate the use and distribution of organic seed by improving the transparency of the organic seed market. Each EU Member State can establish its own database, resulting in different specific technical solutions among countries. This study evaluated the quality of organic seed databases in place in the EU countries (including the United Kingdom and Switzerland) through an online survey. An Information Systems Success Model was used as a framework of our evaluation. The respondents assessed the Ease of use, Comprehension and Completeness of the databases. Based on 537 responses obtained from farmers, seed suppliers and certification bodies, our analysis revealed that the Completeness of the databases was evaluated as the most critical aspect. Interactive fully computerised databases should be preferred to the provision of static files as they positively influence perceived completeness. In addition, the support provided by the database managers on how to use databases and a straightforward administrative process for the registration of seed offers or the management of derogations can increase databases comprehensibility and ease of use
