Abstract This article aims to decipher distinctive conceptual characteristics attributed to the legendary founder of Ḥasidism, Israel Baʿal Shem Ṭov, as documented by his faithful disciple, Jacob Joseph of Polonnoye (1710–1784). I endeavor to demonstrate how a quantitative analysis of the earliest testimonies of Beshtian teachings can improve our understanding of the interplay between major concepts within these teachings. To achieve this objective, I apply a combination of statistical tools of distant reading with textual analysis of close reading. It will reveal singular characteristics of the reported teachings of the Beshṭ, while distinguishing them from the textual corpus into which they were integrated, Jacob Joseph’s writings: Sefer Toldot Yaʿaqov Yosef (1780), Ben Porat Yosef (1781), and Ṣafnat Paʿneaḥ (1782). The results indicate a significant focus on negativity—moral, emotional, and conditional—as well as verbs that offer followers guidance regarding how to overcome these negative aspects of the human experience.

While Holocaust museums have embraced social media to connect with online audiences and provide educational materials, the specifics of their use are not well understood. A Delphi study involving 22 experts developed a framework for examining Holocaust-related social media content. This framework, the result of a three-round iterative process, includes three main areas: Historical content of the Holocaust, Contemporary issues related to the Holocaust, and Museum activities and communication. The hierarchical system of categories can help users explore the vast range of online materials and help educators identify effective strategies for using social media content in Holocaust education.

The seismogenesis of rocks is mainly affected by their mineral composition and in situ conditions (temperature and state of stress). Diverse laboratory experiments have explored the frictional behaviour of the rocks and rock-forming minerals most common in the crust and uppermost mantle. However, it is debated how to “upscale” these results to the lithosphere. In particular, most earthquakes in the crust nucleate down to the crustal seismogenic depth (CSD), which is a proxy for the maximum depth of crustal earthquake ruptures in seismic hazard assessments. In this study we propose a workflow to upscale and validate those laboratory experiments to natural geological conditions relevant for crustal and upper-mantle rocks. We used the southern Caribbean and northwestern South America as a case study to explore the three-dimensional spatial variation of the CSD (mapped as D90, the 90 % percentile of hypocentral depths) and the temperatures at which crustal earthquakes likely occur. A 3D steady-state thermal field was computed for the region with a finite-element scheme using the software GOLEM, considering the uppermost 75 km of a previously published 3D data-integrative lithospheric configuration, lithology-constrained thermal parameters, and appropriate upper and lower boundary conditions. The model was validated using additional, independent measurements of downhole temperatures and heat flow. We found that the majority of crustal earthquakes nucleate at temperatures less than 350 ∘C, in agreement with frictional experiments of typical crustal rocks. A few outliers with larger hypocentral temperatures evidence nucleation conditions consistent with the seismogenic window of olivine-rich rocks, and can be due to either uncertainties in the Moho depths and/or in the earthquake hypocentres or the presence of ultramafic rocks within different crustal blocks and allochthonous terranes accreted to this complex margin. Moreover, the spatial distribution of crustal seismicity in the region correlates with the geothermal gradient, with no crustal earthquakes occurring in domains with low thermal gradient. Finally, we find that the largest earthquake recorded in the region (Mw=7.1, Murindó sequence, in 1992) nucleated close to the CSD, highlighting the importance of considering this lower-stability transition for seismogenesis when characterizing the depth of seismogenic sources in hazard assessments. The approach presented in this study goes beyond a statistical approach in that the local heterogeneity of physical properties is considered in our simulations and additionally validated by the observed depth distribution of earthquakes. The coherence of the calculated hypocentral temperatures with those expected from laboratory measurements provides additional support to our modelling workflow. This approach can be applied to other tectonic settings worldwide, and it could be further refined as new, high-quality hypocentral locations and heat flow and temperature observations become available.

Petit-spot volcanoes, occurring due to plate flexure, have been reported globally. As the petit-spot melts ascend from the asthenosphere, they provide crucial information of the lithosphere–asthenosphere boundary. Herein, we examined the lava outcrops of six monogenetic volcanoes formed by petit-spot volcanism in the western Pacific. We then analyzed the 40Ar/39Ar ages, major and trace element compositions, and Sr, Nd, and Pb isotopic ratios of the petit-spot basalts. The 40Ar/39Ar ages of two monogenetic volcanoes were ca. 2.6 Ma (million years ago) and ca. 0 Ma. The isotopic compositions of the western Pacific petit-spot basalts suggest geochemically similar melting sources. They were likely derived from a mixture of high-μ (HIMU) mantle-like and enriched mantle (EM)-1-like components related to carbonatitic/carbonated materials and recycled crustal components. The characteristic trace element composition (i.e., Zr, Hf, and Ti depletions) of the western Pacific petit-spot magmas could be explained by the partial melting of ∼ 5 % crust bearing garnet lherzolite, with 10 % carbonatite flux to a given mass of the source, as implied by a mass-balance-based melting model. This result confirms the involvement of carbonatite melt and recycled crust in the source of petit-spot melts. It provides insights into the genesis of tectonic-induced volcanoes, including the Hawaiian North Arch and Samoan petit-spot-like rejuvenated volcanoes that have a similar trace element composition to petit-spot basalts.

AbstractScrutinizing the diverse history of the Atlantic world reveals intriguing insights into the complex interactions between the Orient and the Occident. While Islamophobia and Orientalism are commonly discussed in relation to Muslims and Arabs, the somewhat archaic term Mahometanism shares semantic similarities but is less familiar in contemporary literature. This study adopts a methodology rooted in literary theory to examine the trajectory of the term Mahometanism in Orientalized discourse from the 11th to the 18th centuries. Comparing European Mahometanism with its American counterpart, this study claims that the former primarily symbolizes the perpetual religious conflict between Christianity and Islam, whereas the latter represents the clash of civilizations, transitioning from religious perspectives to secular attitudes during America’s separation from Britain. Given the scant body of relevant literature, the current study makes a unique contribution by offering a deeper understanding of the evolvement of Mahometanism over time and its enduring significance in the literary canon alongside its profound implications on past and modern-day anchors between the East and the West.

Abstract. Within the Northern Calcareous Alps (NCA) fold-and-thrust belt of the Eastern Alps, multiple pre-shortening deformation phases have contributed to the structural grain that controlled localization of deformation at later stages. In particular, Jurassic rifting and opening of the Alpine Tethys led to the formation of extensional basins at the northern margin of the Apulian plate. Subsequent Cretaceous shortening within the Northern Calcareous Alps produced the enigmatic Achental structure, which forms a sigmoidal transition zone between two E–W-striking major synclines. One of the major complexities of the Achental structure is that all structural elements are oblique to the Cretaceous direction of shortening. Its sigmoidal form was, therefore, proposed to be a result of forced folding at the boundaries of the Jurassic Achental basin. This study analyses the structural evolution of the Achental structure through integrating field observations with crustal-scale physical analogue modelling to elucidate the influence of pre-existing crustal heterogeneities on oblique basin inversion. From brittle–ductile models that include a weak basal décollement, we infer that oblique shortening of pre-existing extensional faults can lead to the localization of deformation at the pre-existing structure and predicts thrust and fold structures that are consistent with field observations. Consequently, the Achental low-angle thrust and sigmoidal fold train was able to localize at the former Jurassic basin margin, with a vergence opposite to the controlling normal fault, creating the characteristic sigmoidal morphology during a single phase of NW-directed shortening.

The structural styles and magnitudes of Alpine tectonic inversion are reviewed for the Atlantic margin of southwestern (SW) Iberia, a region known for its historical earthquakes, tsunamis and associated geohazards. Reprocessed, high-quality 2D seismic data provide new images of tectonic faults, which were mapped to a depth exceeding 10 km for the first time. A total of 26 of these faults comprise syn-rift structures accommodating vertical uplift and horizontal advection (shortening) during Alpine tectonics. At the regional scale, tectonic reactivation has been marked by (a) the exhumation of parts of the present-day continental shelf, (b) local folding and thrusting of strata at the foot of the continental slope, and (c) oversteepening of syn- and post-rift sequences near reactivated faults (e.g. “passive uplift”). This work proves, for the first time, that geometric coherence dominated the growth and linkage of the 26 offshore faults mapped in SW Iberia; therefore, they are prone to reactivate as a kinematically coherent fault network. They form 100–250 km long structures, the longest of which may generate earthquakes with a momentum magnitude (Mw) of 8.0. Tectonic inversion started in the Late Cretaceous, and its magnitude is greater close to where magmatic intrusions are identified. In contrast to previous models, this work postulates that regions in which Late Mesozoic magmatism was more intense comprise thickened, harder crust and form lateral buttresses to northwest–southeast compression. It shows these structural buttresses to have promoted the development of early stage fold-and-thrust belts – typical of convergent margins – in two distinct sectors.

AbstractIn the practice of international journalism, the imagination used by journalists and publishers is helpful for understanding the country, but it also has the drawback of creating a ‘fog’ on the contrary. Mongolia was a mysterious country like an enigma to foreigners. To open it, foreigners wrote with various ideas. Did their stereotypes succeed? Based on such questionable assumptions, the circle analysis is presented. Stereotypes regarding Mongolia were examined in pieces published in the American Press between 1868 and 1968. To begin, stereotypes were extracted from the texts using content analysis. Second, on the topics of stereotypes, the study has discovered five frames of stereotypes. In the end the study examined the many meanings of stereotypes in frames. Some of these meanings could be the ‘fog’ that is distorting Mongolian understanding. However, other definitions may be more extensive, leading to a better comprehension of Mongolia. To recap all of these misconceptions, publications in the American press revealed admissible information about Mongolia at that time. This validates the five-frame analysis proposed in this study of Mongolian stereotypes in the American press.
