This paper interrogates two important but obscured admission policy developments at leading American universities in the post-World War II era. First, we critically examine the University of California’s “special admissions,” later formalized as the “Admission by Exception” policy adopted at two flagship campuses (Berkeley and UCLA) to open opportunities for veterans returning from the War under the GI Bill. The scale of this Admission by Exception policy was orders of magnitude larger than any comparable admissions policy in recent decades, including both the eras with and without legally permissible affirmative action. Second, we excavate archival evidence from the immediate aftermath of the 1954 Brown v. Board of Education decision, where leaders at the flagship University of Texas at Austin campus hastily adopted a new standardized exam requirement because their enrollment modeling indicated this was the most efficient way to not face further losses in federal court while excluding the largest number of African Americans (and thereby resisting Brown) and maintaining the same overall size of the freshmen class. These two post-war admission policy changes, one arising in de facto segregated California and the other in de jure segregated Texas, operated as racialized institutional mechanisms analogous to “redlining” racially restrictive housing policies that are a more familiar feature of the post-War era. We draw on historical data about earnings and wealth accumulation of the overwhelmingly white graduates of UC and UT in the 1950s–70s and connect these findings to the theoretical frameworks of Cheryl Harris’s “whiteness as property” and George Lipsitz’s racialized state investment. We show how these admission policies contributed to the intergenerational transfer of advantage. We then turn to the contemporary admissions landscape at highly selective American universities after the Supreme Court’s SFFA v. Harvard ruling. We link current trends at some elite institutions toward a return to standardized testing requirements, maintaining considerations of athletic ability mostly in “country club” sports as manifestations of bias in university admissions, which tend to favor white applicants (Jayakumar and Page 2021; Jayakumar et al. 2023b). The paper connects historical racialization of admissions to ongoing inequities in access and outcomes, showing how both historical and contemporary admissions policies reward inherited forms of cultural capital aligned with whiteness.

The importation of prefabricated buildings into colonies was a prevalent practice during the British colonial expansionist venture. However, in post-colonial Nigeria today, many of these prefabricated houses have either been largely modified or have vanished without architectural or written records. This undocumented disappearance poses a challenge to the development of architectural restoration proposals for the remaining few, especially with the authenticity of materials, as well as their morphology, configuration, use, and function being heavily contested. Among the remaining few that have undergone layers of modifications and are on the verge of total collapse is the Egbo Egbo Bassey House, imported and built in Old Calabar between 1883 and 1886 and declared a National Monument of Nigeria in 1959. Given the dearth of architectural and historical data, this paper aims to reconstruct its architectural morphology, chronological modification, and historical uses and functions, with the view of developing an evidence-based architectural restoration proposal for its adaptive reuse. The data was collected through semi-structured interviews (n = 16), archival research at the National Museum (archival file ID: TF128/C.25/A and TF120/C.20/A), and a measured architectural survey, which was performed using laser tapes and laser rangefinders. Annotated building images were captured using a Canon 5D Mark III and a DJI Marvic 3 drone. Comparative analysis with two other exemplars of prefabricated houses in the region was also conducted to consolidate oral, archival, and field data. Three architectural modification stages, namely 1886, 1959, and 2012, were determined for the analytical framework. Architectural outputs include measured 2-dimensional drawings (scale 1:50) and 3-dimensional models for the three historical stages. The accuracy of each model was ensured through methodical triangulation and confidence rubric ratings. The result of this paper provides a replicable inquiry methodology, which can be used to develop an evidence-based workflow for developing a restoration proposal for architectural heritage in contexts where architectural and historical data are not available or contested. As a limitation, this research does not include an analysis of wood typology, structural testing, and statistical analysis of material. Full article

This study presents the preliminary results of the design and implementation of an advanced data management infrastructure developed to enhance the study, interpretation, and preservation of historical and archaeological contexts. Conducted within the framework of the PNRR CHANGES Project, Spoke 6, the initiative promotes the integration of scientific research, digital innovation, and cultural heritage enhancement. One of the principal outcomes of the project is the development and configuration of ARPAS (“Analisi del Rischio nel Paesaggio Stratificato” or “Risk Analysis of Stratified Landscape”), a centralised Geospatial Database capable of ensuring reliable data archiving, real-time analytical processing, and collaborative information sharing among researchers and institutions engaged in cultural heritage management. The paper discusses key methodological challenges related to the heterogeneity of available documentation and the limitations of existing tools currently used for heritage research and protection in the Italian, and particularly Sicilian, context. At the same time, it highlights the potential of the proposed system in terms of data accessibility, verifiability, and query ability, as well as its ability to integrate and interrelate heterogeneous datasets within a multilayered, interdisciplinary framework for cultural landscape research. The pilot deployment focuses on a geographic area in southeastern Sicily, drawing upon documentation of the cultural landscape across four provinces—Agrigento, Catania, Ragusa, and Siracusa—and integrating archaeological, architectural, and environmental data to support risk assessment and heritage conservation strategies. Results appear to demonstrate ARPAS’s potential to improve the completeness of information, manage stratification across temporal layers, and support predictive and preventive analyses for cultural heritage at the landscape level.

For many historic engineering structures, including early 20th-century truss bridges, no comprehensive technical documentation has survived, making them highly vulnerable to irreversible loss. This study addresses this challenge by developing and testing a non-invasive, UAV-based photogrammetric methodology for the comprehensive documentation of the Niestępowo railway viaduct in Northern Poland. A dense geodetic control network was established using GNSS and total station measurements, providing a metrically verified reference framework for 3D reconstruction. Two photogrammetric software platforms—Bentley ContextCapture and Agisoft Metashape—were employed and comparatively evaluated in terms of processing workflow, accuracy, and model fidelity. To ensure methodological robustness, both tools were used for cross-validation of the generated 3D models and for the comparative assessment of their dimensional consistency against archival documentation. The results confirm that both platforms can produce highly accurate, photorealistic 3D models suitable for engineering inventory and heritage preservation, with Agisoft Metashape yielding slightly higher geometric precision, while Bentley ContextCapture ensured superior automation for large datasets. The generated 3D models reproduced details such as rivets, cracks, and corrosion marks with millimeter-level accuracy. The presented workflow demonstrates the potential of UAV photogrammetry as a reliable and scalable method for safeguarding cultural and technical heritage. By enabling the creation of metrically precise digital archives of historic bridges, the methodology supports future conservation, monitoring, and restoration efforts—preserving not only physical form but also the historical and engineering legacy of these structures.

Al-Madafah (the guesthouse) is a cornerstone of the cultural and social fabric of Sweida Province in southern Syria. Rooted in the Druze community’s history following their settlement in Jabal al-Arab in the 17th century, these structures have served as spaces for hospitality, cultural exchange, political resistance, and community cohesion. Despite their significance, scholarly research on Madafahs in Sweida remains limited. This article examines their architectural design, socio-cultural roles, and historical evolution to uncover this understudied tradition and advance conservation efforts for this heritage. Combining archival research, case studies, and oral histories from residents and experts, this study employs narrative analysis to decode the cultural meanings embedded in these spaces. Findings reveal that Madafahs are more than architectural landmarks; they serve as living embodiments of resilience, cultural pride, and communal identity, fostering social cohesion, while their basalt stone construction reflects Jabal al-Arab’s vernacular heritage. Historically, they hosted revolutionary activities against colonial rule. Today, urbanisation and economic pressures threaten their traditional role, yet they endure as symbols of continuity. This study highlights Madafahs as valuable heritage sites and cradles for narratives of magnanimity and defiance. Collaborative efforts between stakeholders and policymakers could revitalise these spaces, ensuring that their legacy persists amid modern challenges. Full article

The Boxer Rebellion, as a significant historical episode in modern Chinese history, has been primarily studied through official archives and Boxer propaganda Posters. Chinese Christian literature remain underutilized in current scholarship. Quan Huo Ji 拳祸记 (The Record of Boxer Rebellion), is an important ecclesiastical document, compiled by the Catholic priest Li Wenyu. While reflecting an apologetic stance, it nonetheless provides valuable insights from the perspective of common people and narrates the experiences of marginalized individuals, offering a systematic account of the suffering endured by various dioceses. Within this text, three categories of common people emerge. First, the lay faithful, who, under the violent threat of “apostasy or death”, remained steadfast in their faith. Second, anti-Christian civilians, whose motivations—though often framed as expressions of national or social grievance—may in fact reflect a release of personal frustrations and desires. Third, those sympathetic to Christians either maintained a neutral stance or offered assistance within their limited capacity. These individual experiences, often overlooked by mainstream historiography, compensate for the limitations of conventional analytical frameworks. They also vividly illustrate how ordinary people navigated between forced compromise and active resistance. Through a microhistorical lens, these personal trajectories offer a multi-dimensional portrayal of the survival dilemmas. Full article

The British colonial contact with Nigeria was dotted with diverse paradoxes. In the realm of architecture, it was a period punctuated with the importation of prefabricated buildings into many slave and palm oil trading towns, such as Old Calabar in southern Nigeria. Unfortunately, today, many of these prefabricated colonial architectural heritages have gone into extinction, except for a few which are also on the verge of collapse. One of the remaining few on the verge of collapse is the Egbo Egbo Bassey House built between 1883 and 1886 and declared a National Monument of Nigeria in 1959. Currently, there is no literature on the historical and architectural data of this building, besides those scattered over several files in archival records. Therefore, this paper aims at the holistic documentation of the National Monument. Two categories of data were considered in the documentation processes—namely the building historical data and geometrical data. Historical data were collected through archival research and interviews, while the geometrical data were collected through close-range photogrammetry and manual measurements. The result of this paper contributes to the current geographical dearth of literature on British prefabricated architectural heritage, which punctuated a very important period in the architectural history of the world.

The cultural heritage of the Liao dynasty in Chifeng encompasses significant historical and cultural information that requires systematic digital preservation and management. However, heterogeneous data sources across museums, archives, and research institutions lack semantic interoperability, creating barriers for cross-system integration and knowledge discovery. This study proposes a standardized knowledge graph construction method by integrating the CIDOC Conceptual Reference Model version 7.2 with large language models. A unified ontology framework enables semantic consistency across diverse heritage data, while Generative Pre-trained Transformer-based models automatically extract structured triples from unstructured texts through prompt engineering and entity disambiguation, with the resulting knowledge graph implemented in Neo4j graph database. The constructed knowledge graph integrates 106 immovable cultural heritage records from Chifeng City with approximately 20 types of semantic relationships, forming a comprehensive semantic network covering people, places, events, time, and materials. K-means clustering reveals five cultural value themes, including “Nomadic Imperial Power System” and “Multi-Capital Governance Network”, while geospatial mapping identifies a “dual-core and ring-belt” distribution pattern for heritage protection zoning. This research demonstrates how international semantic standards can be integrated with artificial intelligence technologies to enable interoperable cultural heritage knowledge systems, providing practical implications for cross-institutional heritage management and archaeological survey planning.

This article explores the nature of forced consent in 1950s child adoptions from Greece to the United States. It contributes to critical adoption studies by centering the lesser-known “sending country” of Greece and by drawing from a rare combination of biographical data and testimonies, microhistorical contexts, and otherwise scant archival sources. At stake is the exceptionally well-documented treatment of a Greek birthmother who consented to the overseas adoption of her daughter under conditions of socioeconomic pressure. The article illustrates and denounces the aggressive postwar American approach to child adoption from Greece, which left no room for a strengths-based approach to the dependent nation, let alone to the unwed birthmother. The systemically disempowered birthmother and adopted daughter become paradigmatic of many more such seemingly private but essentially biopolitical adoption processes, which may elude notice for lack of proper documentation. Drawing also on conversations with the affected adoptee in later life, this article further endorses recent child-centered, diachronic historical methods and interdisciplinary approaches, as well as a call for truth and reconciliation.

Research in the field of cultural heritage has grown due to the need to preserve cultural assets that serve as witnesses to history and culture. In conservation and restoration, research on traditional papers is extensive, but translucent papers have received less attention. These documents, of proteinaceous, cellulosic, or synthetic origin, achieve transparency through processes that modify their structure, which makes them more vulnerable to aging. Their degradation is aggravated by inadequate storage and handling, posing challenges because they do not respond well to conventional treatments. This study analyzes these issues using documents from the late nineteenth and primarily the twentieth century, sourced from the Provincial Historical Archive of Granada and the Archive of the Higher Technical School of Architecture in Granada. Through visual, photographic, and bibliographic study, a theoretical and graphic catalogue of the most significant deteriorations has been developed. Concurrently, a physicochemical analysis was applied using techniques such as colorimetry, X-ray Fluorescence Spectroscopy (XRF), and Fourier-Transform Infrared Spectroscopy (FTIR). These tools make it possible to relate the material composition of the documents to their state of preservation. This work provides deeper knowledge about the degradation mechanisms of these supports and lays the foundations for the development of specific restoration strategies for this documentary typology.

Detecting topographic change in mountainous areas using historical aerial imagery is challenging due to complex terrain and variable data quality. This study evaluates the potential of Structure from Motion (SfM) for deriving 3D information from archival photograms in the Rabbia basin (Central Italian Alps), a catchment with a well-documented history of debris flow activity. The aim is to assess the impact of input configurations and photogrammetric processing strategies on the quality and interpretability of 3D reconstructions from historical aerial imagery, as a basis for further geomorphological analyses. A 1999 aerial dataset was processed via SfM workflow to generate a point cloud and orthomosaic, and then co-registered with a 2021 LiDAR-derived dataset. Multi-temporal analysis was conducted using point cloud distance computations and visual interpretation of orthomosaics. Additional aerial images spanning nearly 80 years expanded the temporal scale of the analysis, providing valuable retrospective insight into long-term terrain evolution. The results, although considered semi-quantitative due to data quality limitations, are consistent with geomorphological trends in the area. The study confirms that historical SfM-derived products, when supported by robust co-registration and quality checks, can contribute to sediment dynamics and hazard evaluation in alpine environments, though result interpretation should remain cautious due to dataset-specific uncertainties.

The Red-legged Partridge (Alectoris rufa, Phasianidae) is a non-migrant gamebird endemic to southwestern Europe that was introduced into Mediterranean and Atlantic islands in historical times. This is the case for Madeira, Portugal, where a population morphologically assigned to A. r. hispanica has been present since the XV century. We assessed its genetic identity using 2248 (Cytochrome-b, Cyt-b + Control Region, CR) and 297 bp-long (CR) mitochondrial DNA sequences obtained from modern and archival (1900–1964, including Caccabis rufa maderensis syntypes) partridges, respectively. These sequences were compared against an already published dataset covering the entire Iberian A. rufa range. We found that all the haplotypes of modern birds from Madeira were private to this island. The putative subspecies was confirmed, and northern Portugal with northwestern Spain turned out to host the closest mainland populations. This result was in line with the origin of the first human settlers of Madeira from, among other historical provinces, Douro Litoral and Minho, the latter neighboring Galicia. Despite relatively recent A. rufa importations from continental Europe, we did not find any significant change over time in the haplotypic pattern of Madeiran partridges as well as any evidence for maternal introgression from species such as the congeneric Chukar Partridge (A. chukar). Studies relying on genome-wide markers and including the only captive-bred population of Madeira are needed to gain more comprehensive information for the management of the local A. rufa.

This article formulates and evaluates historical hypotheses on the origin and formation of the Villafañe lineage in Santiago del Molinillo (León) within the broader dynamics that connected the urban patriciate and the rural hidalguía (minor nobility) of late medieval and early modern Castile. Through an integrated examination of population registers, parish records, hidalguía lawsuits, and notarial protocols, the study reconstructs the family’s trajectory and its institutional anchoring in the concejo and parish. The evidence suggests an urban origin on León’s Rúa through Doña Elena de Villafañe y Flórez, whose marriage to Ares García—an hidalgo from the Ordás area—established the local house and the compound surname “García de Villafañe” as both an identity marker and a patrimonial device. The consolidation of the lineage resulted from deliberate family strategies, including selective alliances with neighboring lineages (Quiñones, Gavilanes, Rebolledo), participation in municipal and ecclesiastical offices, and the symbolic use of heraldry and memory. The migration of Lázaro de Villafañe to colonial La Rioja and Cordova in the seventeenth century extended this social status across the Atlantic while maintaining Leonese continuity. Although the surviving evidence is fragmentary, convergent archival, onomastic, and heraldic indicators support interpreting the Molinillo branch as a legitimate and adaptive extension of the urban lineage. By combining genealogical and microhistorical analysis with interdisciplinary perspectives—particularly gender and genetics—this article proposes a transferable framework for testing historical hypotheses on lineage continuity, social mobility, and identity formation across early modern Castile and its transatlantic domains.

State-of-the-art historical global burned area (BA) products largely rely on MODIS data, offering long temporal coverage but limited spatial resolution. As a result, small fires and complex landscapes remain underrepresented in global fire history reconstructions. By contrast, Landsat provides the only continuous satellite record extending back to the 1980s, with substantially finer resolution. However, its use at a global scale has long been hindered by infrequent revisit times, cloud contamination, massive data volumes, and processing demands. We compared MODIS FireCCI51 with the only existing Landsat-based global product, GABAM, in a mountainous region characterized by frequent, small-scale fires. GABAM detected a higher number of burn scars, including small events, with higher Producer’s Accuracy (0.68 vs. 0.08) and similar User’s Accuracy (0.85 vs. 0.83). These results emphasize the value of Landsat for reconstructing past fire regimes in complex landscapes. Crucially, recent advances in cloud computing, data cubes, and processing pipelines now remove many of the former barriers to exploiting the Landsat archive globally. A more systematic integration of Landsat data into MODIS-based routines may help produce more complete and accurate databases of historical fire activity, ultimately enabling improved understanding of long-term global fire dynamics.

Coastal boulder deposits (CBDs) are among the most striking geomorphic signatures of extreme wave activity, recording the action of both tsunamis and severe storms. Their significance extends beyond geomorphology, providing geological archives that capture rare but high-impact events beyond the scope of instrumental or historical records. This review critically examines the origins, emplacement mechanisms, diagnostic morphology, monitoring tools, and global case studies of CBDs with the aim of clarifying the storm–tsunami debate and advancing their application in coastal hazard assessment. A systematic literature survey of 77 peer-reviewed studies published between 1991 and 2025 was conducted using Scopus and Web of Science, with inclusion criteria ensuring relevance to extreme-wave processes, geomorphic analysis, and chronological methods. Multiproxy approaches were emphasized, integrating geomatics (RTK-GPS, UAV-SfM, TLS, LiDAR), geochronology (¹⁴C, U–Th, OSL, cosmogenic nuclides, VRM), and hydrodynamic modeling. Findings show that tsunamis explain the largest and most inland megaclasts, while modern storms have proven capable of mobilizing boulders exceeding 200 t at elevations up to 30 m. Many deposits are polygenetic, shaped by successive high-energy events, complicating binary classification. CBDs emerge as multifaceted archives of extreme marine forcing, essential for refining hazard assessments in a changing climate. Full article
