Highlights
• The Munich Procedure, developed for p-XRF data, standardises coefficient corrections.
• It ensures consistent, reproducible data, benefiting specialists in various industries.
• The protocol, documented as R-Skript, enhances accuracy and transparency of p-XRF data.
• Establishing a common baseline fosters discussion and improves the overall understanding of p-XRF.
Abstract
The Munich Procedure, a protocol presented as R code and initially developed on the basis of archaeometric portable X-ray fluorescence (p-XRF) data, offers adaptability and standardisation to evaluate coefficient corrections. These corrections are derived from linear regressions calculated by comparing p-XRF values with laboratory chemical analyses of the same sample set. The versatility of this procedure allows collaboration and ensures consistent data structure. Not tied to specific instrumentation, this approach helps to universally improve the accuracy of p-XRF data, benefiting specialists in a variety of industries. By providing a common baseline for performance evaluation, it enables discussion across different applications.
Korean immigrants have migrated to New Zealand over the past three decades in search of a happier and more balanced life. While they anticipated that their children would be integrated into New Zealand society, they have primarily settled in Korean ethnic enclaves. In this context, younger Korean New Zealanders have been exposed to and influenced by New Zealand’s national and Korean ethnic cultures. This study examined success beliefs and well-being among Korean youth in New Zealand with a Third Culture Kid background (TCK K-NZ) in comparison to Korean youth in Korea (K-Korean) and European New Zealand youth (Pākehā). Results indicated that TCK K-NZ youth endorsed extrinsic success similarly to K-Korean youth, but that valuing extrinsic success predicted lowered well-being only for K-Korean youth. Conversely, valuing intrinsic success predicted higher well-being across the three groups. Results also revealed that TCK K-NZ youth's well-being levels were between those of K-Korean and Pākehā youth, potentially influenced by different structural relations between success beliefs and well-being, as well as their position as “third culture kids” in New Zealand. This study contributes to understanding cultures' roles in formulating success beliefs and the relationship between success beliefs and well-being for Korean New Zealander youth.
Honey and other bee products were likely a sought-after foodstuff for much of human history, with direct chemical evidence for beeswax identified in prehistoric ceramic vessels from Europe, the Near East and Mediterranean North Africa, from the 7th millennium BC. Historical and ethnographic literature from across Africa suggests bee products, honey and larvae, had considerable importance both as a food source and in the making of honey-based drinks. Here, to investigate this, we carry out lipid residue analysis of 458 prehistoric pottery vessels from the Nok culture, Nigeria, West Africa, an area where early farmers and foragers co-existed. We report complex lipid distributions, comprising n-alkanes, n-alkanoic acids and fatty acyl wax esters, which provide direct chemical evidence of bee product exploitation and processing, likely including honey-collecting, in over one third of lipid-yielding Nok ceramic vessels. These findings highlight the probable importance of honey collecting in an early farming context, around 3500 years ago, in West Africa.
Until today, iron gall ink is classified as an exceptional underdrawing material for paintings. Its study and definite identification is usually based on invasive analysis. This article presents a new non-destructive approach using micro-X-ray fluorescence scanning (MA-XRF), LED-excited IRR (LEDE-IRR) based on a narrow wavelength-range of infrared radiation (IR) for illumination and stereomicroscopy for studying and visualising iron gall ink underdrawings. To assess possibilities and limits of these analytical techniques, the approach was tested on panel paintings by Hans Holbein the Elder and Giovanni Battista Cima da Conegliano. Results are compared to invasive examinations on cross-sections using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX). The holistic setup could successfully visualise iron gall ink underdrawings, allowing to harness the formerly invisible underdrawing lines for interdisciplinary studies.
This study will consider the various aspects of the portrayal of Sultan ʿAbd al-Ḥamīd II that were emphasized in the Arab-Islamist revisionist writings about Islamic history. The focus will be especially on the writings of Anwar al-Ǧundī (1917–2002), an Egyptian Islamist writer as it was he who first adopted the process of an “Islamic revision of Islamic history”. His main academic output consisted in responding to the “Orientalist attack on Islam”, and he wrote a number of books towards this aim as as-Sulṭān ʿAbd al-Ḥamīd wa l-ḫilāfa al-islāmiyya, al-Islām fī maʿrakat at-taġrīb and al-Istiʿmār wa l-Islām.
This will be followed by an analysis of the ideological exploitation of the historical personality, and the consequences of the contemporary historical Islamist vision for the development of religious thought.
Im Folgenden soll ein kurzer Überblick gegeben werden über die schiitische Sicht der frühislamischen Geschichte sowie über einige Phänomene, die sich daraus ergeben haben. Sie sind Hindernisse einer islamischen Einheit und müssten, sollte ein ernsthafter Versuch einer solchen verfolgt werden, mit deutlich mehr Mut angegangen werden. Dabei geht es hier weniger darum, alle Unterschiede zwischen Schia und Sunna aufzuzeigen, als sich auf die wirklich problematischen Felder zu konzentrieren, die nicht Folgen späterer, oft zufälliger Entwicklungen sind, sondern Weichenstellungen, die in der Frühgeschichte zu verorten sind. Bisher werden diese neuralgischen Punkte bei den Versuchen einer islamischen Ökumene, um diesen sehr christlich belegten Begriff an dieser Stelle doch einmal zu verwenden, meist umgangen, weil man um ihre Brisanz und Sprengkraft weiß. Doch müsste die Auseinandersetzung mit den unterschiedlichen Geschichtsbildern erfolgen, da sie ein wichtiges innerislamisches Differenzkriterium bilden; zumindest sollte man sich klar darüber sein, dass es unterschiedliche Geschichtsbilder gibt und sie ein Differenzkriterium bilden.
