Tight Bounds for the Price of Anarchy of Simultaneous First Price Auctions [PDF]

open access: yes, 2015
We study the Price of Anarchy of simultaneous first-price auctions for buyers with submodular and subadditive valuations. The current best upper bounds for the Bayesian Price of Anarchy of these auctions are e/(e-1) [Syrgkanis and Tardos 2013] and 2 ...

Use of Mixed Item Response Theory in Rating Scales

open access: yeslnternational Electronic Journal of Elementary Education, 2019
This study aimed to compare the Graded Response Model (GRM) and the Mixed-Graded Response Model (MixGRM) in terms of model data-fit and parameters and demonstrate the application of MixGRM on real data. In this context, this study is basic research based on the International Computer and Information Literacy Study in 2013 conducted with eighth-grade ...

Disentangling correlation between speed and ability at the subject level and between intensity and difficulty at the item level from psycholinguistic data: a joint modeling approach [PDF]

open access: yes, 2011
In psycholinguistic experiments multiple subjects are faced with multiple test items. Despite the early 70's paper of Clark (1973) arguing that averaging reaction times from such experiments over items for each subject and averaging over subjects for ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
