The Data Dilemma: Authors' Intentions and Recognition of Research Data in Educational Technology Research
Sandra Schulz, Natalie Kiesler

The Data Dilemma: Authors' Intentions and Recognition of Research Data in Educational Technology Research
Educational Technology (EdTec) research is conducted by multiple disciplines, some of which annually meet at the DELFI conference. Due to the heterogeneity of involved researchers and communities, it is our goal to identify categories of research data overseen in the context of EdTec research. Therefore, we analyze the author's perspective provided via EasyChair where authors specified whether they had research data to share. We compared this information with an analysis of the submitted articl…

Measuring Information Richness in Product Images: Implications for Online Sales
A common challenge for e-commerce sellers is to decide what product images to display on online shopping sites. In this paper, we propose and validate a novel metric, k-value, to quantify the information richness of an image set, and we further investigate its effect on consumers' purchase decisions. We leverage patch-level embeddings from Vision Transformers (ViT) and apply k-means clustering to identify distinct visual features, defining k-value as the number of clusters. An online experiment…

Love beyond Einstein: Metric reconstruction and Love number in quadratic gravity using WEFT
We study tidal Love numbers of static black holes in four-dimensional quadratic theory of gravity, extending the result of GR. We use worldline effective field theory (WEFT) methods to compute metric perturbations from one-point functions, treating the higher-derivative terms perturbatively. We show that insertions of scalar fields on the worldline induce non-zero tidal tails, and the corresponding Love number displays no RG running. The same conclusion holds for the insertions of tensor fields…

Chris Arnade was one of my favorite followers on the old place. One of the very few people who thinks very deeply, but also outside of their own silos, to create a cross-disciplinary theory of the world. One of the few people who is truly willing to see the world as it is.
The solutions to our problems will never come from one realm of expertise, but only by synthesizing a strategy from a more holistic world view.

Som autist kjenner jeg en intens fascinasjon for dette bildet. Jeg klarer ikke helt å forklare hvorfor, men hjernen min går i loop på alle detaljene. Fargene, mŸnstrene og alt sammen trigger noe i meg som gjŸr at jeg kan stirre på det i timevis uten å bli lei.
Det fŸles som om bildet har blitt min spesialinteresse akkurat nå. Hver gang jeg ser på det, oppdager jeg noe nytt og spennende som holder meg helt oppslukt. Det gir meg en slags ro og glede som er vanskelig å forklare for andre.…

The poster promotes the Norsk Syndikalistisk Forbund (NSF), the Norwegian Syndicalist Federation affiliated with the International Workers' Association (IAA). It features a black-and-white photo of a large group of people, likely members of the organization. The text "Anarkosyndikalismen i Norge!" ("Anarchosyndicalism in Norway!") is prominently displayed, emphasizing the group's focus on anarcho-syndicalist activism. Contact details for the NSF-IAA appear at the bottom of the poster. The des…

I went to Best Buy to pick up Ethernet and DisplayPort cables (I’m sure I have both in the house… but I couldn’t find them).
Employee: Would you like to sign up for a Best Buy credit card? You could save 10% on your purchase!
Me, thinking: Yeah 10% off of two cables is $3 pal. What an offer.
Me, out loud: No, thank you.
I get that it’s mandated from corporate. I get that you were trained on this sales tactic. And if I was buying a new TV, maybe. But 10% off a cable? P…
