In 2021, the National Research Institute of Cultural Heritage (NRICH) installed a new accelerator mass spectrometer (AMS) to date Korean national heritage. Before conducting radiocarbon dating, the facility was set up and its performance was assessed. AMS system parameters have been optimized. Measurement of standard and blank samples was verified. Intercomparison analyses were also performed using heritage samples. The F14C value of NIST 4990C was 1.3406 and the background level was 0.0024. Both IAEA-C7 and C8 were confirmed to match the reference value within the 1-σ range. The NIST 4990C measurement results confirmed high precision and accuracy, with 1-σ values below 2‰. In the intercomparison, the error for each sample was 2‰. Thus, based on this study, NRICH plans to launch a dating service specializing in cultural heritage.

Hegel's Lectures on the Philosophy of History are notorious for their racist portrayal of Africa. Few scholars, however, have considered their racism to be significant for Hegel's practical philosophy. This is largely because colonialism and Black enslavement appear to conflict with the idea of universal freedom at the heart of Hegel's practical philosophy. In my paper, I argue against this view and defend the claim that Hegel's idea of freedom is linked to white identity. It therefore grounds his racist comments in the Philosophy of History rather than opposing them. In order to show that Hegel's idea of freedom is linked to white identity, I trace its connections with the Western idea of property. My suggestion is that Hegel conceptualizes freedom as appropriation, thereby linking freedom to property and white identity. I conclude that Hegel's idea of freedom is an idea of white freedom and thus not an ‘impartial criterion’ for social critique.

Learning about music, sound or audio can present significant challenges for individuals who are deaf and hard of hearing (DHH). Given the advancements in technology and the increasing emphasis on equality, diversity and inclusion (EDI) in education, this article proposes pedagogical approaches aimed at facilitating the learning process for DHH students in the areas of music and audio production. These approaches encompass sound visualisation, haptic feedback, automated transcription, tactics in non-linear editing and digital signal processing. Importantly, these approaches do not necessitate advanced technical skills or substantial additional resources, thus lowering barriers for DHH students to overcome challenges in music and audio production. Furthermore, these strategies would enable content creation and editing for individuals with DHH, who may have previously been excluded from participating in music and audio production. Recommendations are provided for the implementation of these approaches in diverse educational settings to promote the integration of EDI in music and audio education.

The question of deradicalization looms large in the historiography of western European socialism. But in this contested field, the contributions of the New Left historian, Ralph Miliband, have been curiously neglected. Through his work on the British Labour Party, Miliband developed a distinctive account of deradicalization that foregrounds the fact that when parties enter government, party elites find themselves transplanted into new, alien institutions. Over time, he argued, they then come to internalize the worldviews of those institutions and reshape their parties accordingly. This essay presents the first quantitative and cross-national test of this “experience of governing hypothesis,” using Comparative Manifesto Project data from western European socialist parties between 1945 and 2021 and a novel matching technique for panel data. Miliband’s theory is strongly supported by this analysis, which also demonstrates the value of taking a multi-dimensional approach to deradicalization.

We prove a version of the Lefschetz hyperplane theorem for fppf cohomology with coefficients in any finite commutative group scheme over the ground field. As consequences, we establish new Lefschetz results for the Picard scheme.

This paper critically reviews and examines the available data concerning Italians embarked on the SS Arandora Star on 30 June 1940. It encompasses their fate on 2 July when the ship was sunk, their subsequent journeys and the sources used to verify the conclusions. The principal aim is to establish, as far as is possible, the precise number, correct names and other details of those who were embarked on the ship. A fully validated ‘Embarkation Listing’ is published here for the first time.

Tree-ring cellulose is a commonly used material for radiocarbon analysis. Extracting cellulose is labor-consuming and several devices that enable batchwise extraction have been developed. However, these devices bear the risk of sample contamination. The present study describes a new device which improves upon two aspects of currently available devices. First, to prevent cross-sample-contamination, we redesigned the drainage module to enable independent removal of chemical waste from each individual sample funnel. Second, we added covers to the sample funnels to reduce the risk of external contamination. Cellulose purity (i.e., holocellulose) was confirmed by Fourier Transform Infrared (FTIR) Spectroscopy. Furthermore, accuracy of the radiocarbon analysis was confirmed by results of 14C-blank samples and samples of known age. In conclusion, while maintaining labor-saving, our modified device significantly reduces the risk of sample contamination during extraction of tree-ring cellulose.
