Bernard Suits is commonly thought to have defined games as challenges. This paper argues that Suits could not have done so without ruining his larger philosophical project. It then argues that he did not do so. Suits defined game playing in quantitative terms (i.e. being more or less efficient) not qualitative ones (e.g. difficulty, struggle). The paper concludes by exploring the consequences of this shift in perspective. [ABSTRACT FROM AUTHOR]

Northeast China played an irreplaceable role in population migrations and cultural exchanges in East Asia during the Paleolithic. This paper collected 182 archaeological sites to analyse the characteristics of spatial-temporal variations of Paleolithic human activities in Northeast China, and explored the driving mechanisms behind these variations in combination with the paleoenvironmental and archaeological studies. During the Lower Paleolithic, constrained by the relatively cold-dry climate and blocked by the Songnen paleo-lake basin, the population was sparse and distributed only near 40° N at the southern end of Northeast China. Upon entering the Middle Paleolithic, as humans developed greater tolerance to cold climates and adopted more sophisticated survival strategies with the application of small lithic tools, their numbers increased and geographical distribution expanded northward to 45° N at the central region of Northeast China. The Upper Paleolithic saw a considerable increase in population and expansion across almost all of Northeast China except for the eastern Inner Mongolia Plateau. We speculated that 50 ka and 30 ka BP were two key points, both of which may be associated with a significant increase in the frequency of migrations and communications among humans, and the widespread popularity of highly mobile microblade technology, respectively. In addition, the environmental analysis of archaeological sites revealed a continuous spread of Paleolithic humans to areas with higher elevations, steeper slopes, and lower temperatures. Meanwhile, they were becoming less reliant on water resources and were more widely conducting activities in open-air areas, showing that the environmental adaptability had been continuously improving over time. This study can provide a reference for the reconstruction of the migration history of early humans in East Asia, and is also of great significance for a comprehensive understanding of the evolutionary process of early human-environment interactions.

Prehistoric and historic iron metallurgy in the Holy Cross Mountains in central Poland developed along with human Przeworsk Culture activity (during the Roman period) and within the boundaries of the Old-Polish Industrial District (OPID) during the Middle Ages and during recent centuries. At the Świślina catchment, there are many archaeological sites showing intense prehistoric metallurgical activity. The later medieval and modern iron industry was significantly smaller. At the Doły Biskupie site, slags and microscopic iron spherules (hammerscales) were found in alluvia. The microscopic spherules separation method (MSS) enabled analysis of these small artefacts created during iron ore smelting and forging. Iron spherules were detected in floodplain sediments, which are characterized by increased content of trace elements. The presence of these artefacts in shallow sediment layers in the confluence section of the river may be an indicator of archaeologically confirmed prehistoric metallurgical activity in the catchment area. Study of these residues enabled an attempt to reconstruct the river valley environment during the prehistoric and historical period. The MSS method can be used to detect iron spherules in alluvia in other river catchments, confirming the presence of yet-undiscovered bloomery sites. [ABSTRACT FROM AUTHOR]

Disturbances in tropical forests can have long‐lasting ecological impacts, but their manifestations (ecological legacies) in modern forests are uncertain. Many Amazonian forests bear the mark of past soil modifications, species enrichments, and fire events, but the trajectories of ecological legacies from the pre‐contact or post‐colonial period remain relatively unexplored. We assessed the fire and vegetation history from 15 soil cores ranging from 0 to 10 km from a post‐colonial Surinamese archaeological site. We show that (1) fires occurred from 96 bc to recent times and induced significant vegetation change, (2) persistent ecological legacies from pre‐contact and post‐colonial fire and deforestation practices were mainly within 1 km of the archaeological site, and (3) palm enrichment of Attalea, Oenocarpus and Astrocaryum occurred within 0, 1, and 8 km of the archaeological site, respectively. Our results challenge the notion of spatially extensive and persistent ecological legacies. Instead, our data indicate that the persistence and extent of ecological legacies are dependent on their timing, frequency, type, and intensity. Examining the mechanisms and manifestations of ecological legacies is crucial in assessing forest resilience and Indigenous and local land rights in the highly threatened Amazonian forests.

Summary: This paper sets out new recommendations for recording structural iron nails. Despite their ubiquity, iron nails have received limited analytical and interpretative attention and recording practices are highly variable. Too often current recording is time‐consuming and costly without providing meaningful information. This paper proposes a new recording methodology, developed through analysis of the Roman structural nail assemblage from the MHI A14 Cambridge‐Huntingdon excavations alongside experiments in nail shaping, with wider context provided by medieval and post‐medieval assemblages from the City of London. This approach includes a new nail typology, recommendations for bulk recording of basic details for whole assemblages (using counts and typologies), alongside detailed recording (shank morphology and further metric data) for certain nail groups. Shank morphology is a particularly important aspect proposed here, being indicative of how nails were used in antiquity. [ABSTRACT FROM AUTHOR]

Summary: Amber is a material of great social value that has been identified at various archaeological sites on the Iberian peninsula dating to Late Antiquity. The objects, mostly necklace beads, have been discussed to date with limited results in relation to a small number of studies. This article presents the characterization by Fourier Transform Infrared Spectroscopy (FTIR) of 52 amber beads from four Late Antique necropolises in the province of Granada (south‐eastern Iberian peninsula): Cortijo del Chopo (Colomera), El Castillón (Montefrío), Marugán (Atarfe) and Fuente Santa (Loja). The results obtained demonstrate the Baltic origin of the amber at these sites and advance our knowledge of this type of product in Hispanic Late Antique funerary contexts. [ABSTRACT FROM AUTHOR]

The Morgado Superior Rock Shelter is located near the city of Tomar, in Central Portugal. This site presents important funerary contexts that according to published information encompass the Neolithic, Chalcolithic and Bronze Age. Other non-funerary uses have not yet been characterised but were briefly suggested. A faunal sample of the 1988 and 2012 interventions is analysed from a zooarchaeological and taphonomical perspective, focusing on the leporid remains that largely dominate the assemblage. Clear indicators of a human origin are absent, while a configurational approach allows the description of exogenous and intrusive origins. The characteristics of the registered consumption taphonomical indicators are suggestive of scat and non-ingested accumulation by foxes. Furthermore, this study allows us to discuss some aspects of the formation of the stratigraphy of this important cave necropolis, while also serving as an example of the expected results of foxes' action on leporid remains in an archaeological site.

The last two decades witnessed increasing scholarly interest in the history of water management in southern Mesopotamia. Thanks to many geoarchaeological research projects conducted throughout the central and southern Iraqi floodplains, a general understanding of the macrophases of anthropogenic manipulation of this vast hydraulic landscape has been achieved. However, current narratives mostly rely on studies at a regional scale and are based on excessively long chronological phases (often spanning a whole millennium). A finer‐tuned analysis at a submillennial scale is needed to better appreciate the dynamics that led to the development of artificial canals and irrigation systems and the creation of harbours in cities and other navigation‐related facilities. The Iraqi‐Italian QADIS project is addressing this issue through a systematic geoarchaeological investigation in the south‐eastern area of the Qadisiyah province. We aim to update the current narrative by analysing case studies involving specific periods of occupation. We performed 17 boreholes to propose a date on the functioning period of the hydraulic works in five selected archaeological sites of this region. This approach allowed us to understand changes in water management strategies in both the short and the medium term (i.e., on a scale of centuries). In this paper, we present the results for the fourth and third millennia B.C.E. This period witnessed a crucial passage from the basic exploitation of natural watercourses for irrigation and occasional navigation to the emergence of the first system of artificial canals and intraurban harbours.

The Archaeological Site of Panama Viejo (Panama) comprises a protected area of 28 km2 within present‐day Panama City, on America's Pacific coast. In 1519, the Spaniards founded the city of Panama Viejo to secure a natural port in an area inhabited by indigenous peoples since at least the eighth century CE. The site, along the coastline and between two rivers, became a principal gateway for goods and people travelling between Europe and Pacific settlements to the east (Realejo) and the west (Trujillo, Lima, Arica). Within one century, however, Panama Viejo's natural port and freshwater infrastructure collapsed, leading to the city's relocation after corsairs attacked it in 1671. This study combines archaeological, geographical and historical analyses to explain how and why human interactions with the local environment made the settlement increasingly untenable.

This article explores dance improvisation as an alternative mode of understanding the archaeological heritage site beyond representational knowledge. Drawing on projects undertaken on Liangzhu Archaeological Site over the past five years (2018–2023), we have employed dance improvisation as a method for participants to explore here and now interactions with the heritage site, focusing on their sensing, feeling and thinking. Using an A/r/tography methodology, this study considers how intersections of art-making and writing allow new meanings and bodily interpretation to emerge during the improvisation process. Participant reflection notes reveal how embodied encounters create space for rhizomatic interpretations of the archaeological site, transcending power dynamics embedded in existing politically-sacred and archaeologically-authoritative knowledge systems.

In the Arctic region, microbial degradation poses a significant threat to the preservation of archaeological deposits, actively consuming irreplaceable cultural and environmental records. In this study we assess the potential effects of the last 40 years of climate change on organic archaeological deposits within the UNESCO World Heritage area Kujataa in South Greenland. We use the dynamic process-oriented model, CoupModel to simulate soil temperatures and soil moisture contents at four archaeological sites in the area. The results show that the organic deposits have experienced a substantial warming the last 40 years, which combined with decreasing soil moisture contents creates a dangerous combination that can accelerate the degradation of organic materials. Currently, there are 583 archaeological sites registered within the area. Our findings highlight that the current climatic conditions are not conducive to organic preservation. The greatest risk of degradation lies within the relatively dry continental inland areas of the study region, where all Norse Viking Age settlements are situated. However, even at the "cold" and "wet" outer coast, the combined effects of rising summer temperatures and declining soil moisture levels may already be exerting a noticeable impact.

Climatic change appears to influence major patterns in human history. However, confirming the association between climatic events and adaptive human responses is not straightforward given the potential for spurious correlations and uncertainty in the timing of events. Here we leverage theory from behavioral and population ecology to generate predictions about causal relationships between climate and settlement decisions. We then test those predictions using statistical methods designed to evaluate associations under uncertainty. This allows us to evaluate a comprehensive record of radiocarbon dated archaeological sites in the Basin-Plateau region of North America relative to a record of effective precipitation reconstructed using Macrophysical Climate Models. Consistent with theory, the results show that regional populations declined in the mid-Holocene during a prolonged period of reduced precipitation, leading to the abandonment of many major rockshelter sites. Remaining populations concentrated at open-air sites around well-watered sand dune localities where they constructed pithouses and adopted more intensive subsistence practices. These findings illustrate an adaptive response of hunter-gatherer populations to past climate change that supports theoretical predictions and is unlikely to result from spurious correlations or uncertainties in the timing of events.

This paper discusses recent archaeological fieldwork conducted at El Castillejo, a medieval Islamic settlement in Los Guájares, Granada, southern Spain. Results from combined archaeological excavation and archaeoseismological assessment of standing structures suggest that the site was affected by a destructive earthquake during its occupation. Radiocarbon samples and OSL analysis point to a seismic event in the period CE 1224–1266. The earthquake occurred within an area marked by a 'seismological gap' in terms of historic seismicity and the causative fault has been tentatively identified in the Nigüelas-Padul Fault System which lies north of the settlement. This event is not recorded by national or European seismic catalogues and represents the oldest historic earthquake in the Granada area. Our work stresses the significant impact that targeted archaeological investigations can generate in our understanding of the local historic seismicity, thus providing clear implications for seismic disaster prevention and reduction.

Birch bark tar is the most widely documented adhesive in prehistoric Europe. More recent periods attest to a diversification in terms of the materials used as adhesives and their application. Some studies have shown that conifer resins and beeswax were added to produce compound adhesives. For the Iron Age, no comparative large-scale studies have been conducted to provide a wider perspective on adhesive technologies. To address this issue, we identify adhesive substances from the Iron Age in north-eastern France. We applied organic residue analysis to 65 samples from 16 archaeological sites. This included residues adhering to ceramics, from vessel surface coatings, repaired ceramics, vessel contents, and adhesive lumps. Our findings show that, even during the Iron Age in north-eastern France, birch bark tar is one of the best-preserved adhesive substances, used for at least 400 years. To a lesser extent, Pinaceae resin and beeswax were also identified. Through statistical analyses, we show that molecular composition differs in samples, correlating with adhesive function. This has implications for our understanding of birch bark tar production, processing and mode of use during the Iron Age in France and beyond. [ABSTRACT FROM AUTHOR]

This article presents a systematic literature review of publications from 2014 to 2021 using "archaeological site" and "climate change" as keywords, in addition to several terms representing forms of stakeholder engagement. Articles were thematically coded to explore trends at the intersection of climate change, archaeology, and local and Traditional stakeholders. Results show that nearly half of the selected publications did not include local and Traditional stakeholder engagement in studies related to climate adaptation planning for archaeological sites. Synthesis of the results with insights gained from other literature on decolonizing archaeology showed that potential reasons for this gap include (1) the academic publishing culture, (2) archaeology as a predominantly Western discipline, and (3) increasingly available tools for climate change adaptation planning for archaeological sites. This article calls on the academic community to consider holistic stewardship using a landscape approach and to use climate change adaptation planning to elevate local and Traditional stakeholder input and values.

The Santa Vitória Chalcolithic site (southern Portugal) prompts several questions related to the provenance and production technology of artefacts. Archaeological ceramics from two sections of Ditch 1 of the Santa Vitória site were studied by neutron activation analysis and X-ray diffraction for the first time, with the main goal of contributing to the contextualization of the artefacts and better understanding their production processes/technologies and the provenance of raw materials. The results point to a local production of ceramics, since their mineral phases reflect the geological contexts around the archaeological site. The mineralogical assemblage indicates a firing temperature below 850 °C. Iron is the better discriminator of ceramics from both sections, which could be related to the addition of different proportions of temper grains during the ceramics' production. Although trace elements do not serve as discriminating geochemical indicators for the analyzed samples, they do imply a slightly higher heterogeneity in the composition of the ceramic paste from section 2. The negative Eu anomaly found in two samples is in accordance with the lower contents of Na2O, related to plagioclase weathering. Detailed studies on ceramics and potential raw materials are foreseen to assist in discussing the role of this Chalcolithic archaeological site at a regional level. [ABSTRACT FROM AUTHOR]

This study explores the perception of a "sense of place" among tourists visiting Hegra, an archaeological site in northern Saudi Arabia, through reviews on TripAdvisor. The 267 reviews on TripAdvisor between 2020 and 2023 were analyzed using the VADER sentiment polarity analysis tool and object modeling using the NMF machine learning algorithm. The results highlight positive factors linked to the history and uniqueness of the place while showing some critical issues related to isolation, cost, privatization, and competitiveness. The originality of the research lies in the type of case study chosen, an archaeological site of a country that has recently opened its doors to tourism, and in the pragmatic nature of the investigation, oriented towards the search for possible solutions to be adopted in terms of heritage management based on the feedback received for the development of the tourist destination.

Khirbat Iskandar is an Early Bronze Age (ca. 3800-1950 BCE) mound in the Madaba Governorate of Jordan. Until a decade ago, it was better known as a key site for the non-urban Early Bronze IV period (ca. 2500-1950 BCE), but is increasingly emerging as a signature site for the urban Early Bronze II-III period (ca. 3050-2500 BCE). The contour of the tall site is shaped by the presence of buried fortifications that were investigated in the north-western sector of the mound, where a long sequence of rebuilds was recognized, but were exposed to and impacted by modern construction activities along the southern and south-eastern areas prior to being recorded. There, due to erosion and weathering, the stone fortifications dating to the first half of the Early Bronze III (ca. 2850-2650 BCE) fell down. In this paper, we report on our strategies to assess threats, document damages, sustainably stabilize, and consolidate the collapsed ancient fortifications in the 2023 field season at Khirbat Iskandar. At the same time, we discuss the conceptual/methodological and practical challenges of identifying best practices in the conservation and preservation of antiquities that collapsed prior to being excavated. We conclude with some thoughts on how to build on these actions to efficiently present the archaeology and cultural heritage at protohistoric sites, like Khirbat Iskandar, and to make it accessible for the local and the international communities.

The article focuses on two significant archaeological sites in North Carolina: Town Creek Indian Mound and the Rankin Museum of American Heritage. It discusses the history, excavations, artifacts, and modern interpretations of these sites, highlighting their importance in understanding Native American culture and history. Additionally, it recommends visiting these sites and suggests acquiring background information beforehand to enhance the experience.

Archaeological evidence for local environmental change is obscured by the tendency for humans to remove natural resources from places of procurement and deposit them elsewhere, sometimes at great distance. This is especially problematic for changes in relative sea level, which clearly affected the inhabitability of low-elevation coastal landforms but not necessarily the regional availability of resources of cultural or economic value. Needed are proxies for relative sea level from non-dietary taxa. One genus of terrestrial snails, Truncatella, offers good potential in this respect because of its specific niche at the interface between seawater and land. However, like food resources displaced by people, Truncatella shells are displaced by storms and redistributed landward of the coastline. Distinguishing between autochthonous and allochthonous deposits is essential to inferring relative sea level from the occurrence of this taxon alone. To this end, assemblages of Truncatella shell from stratified sites along the north Gulf Coast of Florida, USA are compared to associated archaeological snails of other taxa and to snail shells from the wrack of proximate foreshores to infer changes in relative sea level over the past four millennia. Variation in the morphology of shorelines and in the accumulation rates of archaeological midden mitigates any direct relationship between terrestrial snail frequencies and sea level, but the results of this study suggest that our approach can be applied to other non-dietary taxa occupying marginally terrestrial niches to refine estimates for sea level derived from the sedimentary records of geological cores.

This paper presents comparative research on marine shell from four 19th century historical archaeological sites in Melbourne. The shell derives predominantly from Mud Oyster (Ostrea angasi) and Sydney Rock Oyster (Saccostrea glomerata) commercially harvested from natural reefs along the south‐east Australian coastline. The research collects quantitative data that informs on the 19th century oyster industry and investigates inter‐site shell variability and its implications for processing, consumption and discard. Dredging of subtidal reefs provides an explanation for the numerical dominance of oyster, the presence of subfossil cultch (Anadara) and the wide range of minor shellfish. Mud oyster and Sydney rock oyster comparisons in valve size, sided counts and preservation record significant differences within and between sites due to the origins, depositional conditions and the processing of the shell. These data form the basis of two models. The first predicts the archaeological representation of reef dredging and ranks shellfish according to categories, from live oysters to dead shell sampled from the reef substrate. Based on oyster shell anatomy and the separate uses of the right (lid) and left (dish) valves, the second model considers how oyster processing and consumption is characterised archaeologically in differential valve counts and pairing rates.

In 1976, Yosihiko H. Sinoto conducted extensive archaeological survey and excavations on Reao Atoll, Tuamotu Archipelago as part of a Japanese, multi‐disciplinary expedition led by Prof. Sachiko Hatanaka. Primarily excavating three marae and four habitation sites totalling ∼180 m2, more than 25000 vertebrate remains were recovered. We report the jidentification and analysis of the fauna and contrast the inventories from secular and sacred contexts inferring the ritual use of pig, dog, turtle and tuna (Scombridae), as well as identifying relatively larger parrotfish (Scaridae), groupers (Serranidae), snappers (Lutjanidae), the Humphead wrasse (Cheilinus undulatus) and sharks/rays (Elasmobranchii) on marae. With a suite of 11 new AMS age determinations, we report the first directly dated precontact records for pig and dog and anchor the marae chronology possibly beginning in the thirteenth century. The 800 calBP dates imply that at least one of the Tuamotu atolls may have emerged nearly two centuries prior to the hypothesised 'cross‐over' date of 600 BP. Consequently, the earliest chronology of atoll emergence along the 1000 km length of the Tuamotus might vary, thus providing landscapes for human colonisation at slightly different times which has implications for the speed and tempo of colonisation.

The underground powerhouse of the Shuangjiangkou hydropower station is one of the largest caverns under construction in China, and its stability during construction is crucial for safe construction. To study the stability of the surrounding rock during excavation, the displacement and stress of the surrounding rock were monitored by multi-point displacement meters and bolt stress meters. Based on the monitoring data, the elastic modulus, Poisson's ratio, friction angle, and cohesion of surrounding rock were inversely analyzed by the PSO-BP algorithm. Then, the back-analyzed parameters were used to simulate the subsequent excavations and predict the stability of surrounding rock during the following construction. The analysis results show that the surrounding rocks were generally stable during the initial four stages of excavation, and the main factors affecting their stability were blasts and unfavorable geological structures, including the lamprophyre vein and the F1 fault. These unfavorable geological structures also significantly decrease the mechanical parameters of surrounding rock as demonstrated by back analysis, and the stability prediction results show that the omnibus bar cave and the tailrace tunnel were at the greatest risk of instability during the subsequent excavations. This study provides a practical analysis for engineering excavation of the underground caverns. [ABSTRACT FROM AUTHOR]

The decipherment of ancient Chinese scripts, such as oracle bone and bronze inscriptions, holds immense significance for understanding ancient Chinese history, culture, and civilization. Despite substantial progress in recognizing oracle bone script, research on the overall recognition of ancient Chinese characters remains somewhat lacking. To tackle this issue, we pioneered the construction of a large-scale image dataset comprising 9233 distinct ancient Chinese characters sourced from images obtained through archaeological excavations. We propose the first model for recognizing the common ancient Chinese characters. This model consists of four stages with Linear Embedding and Swin-Transformer blocks, each supplemented by a CoT Block to enhance local feature extraction. We also advocate for an enhancement strategy, which involves two steps: firstly, conducting adaptive data enhancement on the original data, and secondly, randomly resampling the data. The experimental results, with a top-one accuracy of 87.25% and a top-five accuracy of 95.81%, demonstrate that our proposed method achieves remarkable performance. Furthermore, through the visualizing of model attention, it can be observed that the proposed model, trained on a large number of images, is able to capture the morphological characteristics of ancient Chinese characters to a certain extent.

Geophysical data inversion typically involves the numerical solution of high-dimensional ill-posed problems. To reduce the non-uniqueness, prior information in the form of appropriate regularization schemes, together with a proper representation of the quantities of interest, is helpful. To this end, methods are recommended that take into account a low-dimensional formulation of the inverse problem, a suitable representation for the quantities of interest, and a helpful numerical procedure. Structural aspects of the objects of interest, such as the dimensions of structures, are often available as prior knowledge in archaeological magnetic surveys. However, they are not easily exploited by classical geophysical data inversion applications; for example, a typical representation together with Tikhonov-like regularization schemes or total variation, which promote smoothness in the solutions, occlude underlying structural information or retrieve fuzzy boundaries. In this work, a three-dimensional inversion of magnetic data is developed based on an evolution strategy. It is adapted to a numerical representation that easily incorporates aspects achievable at archaeological sites. Synthetic test cases and a magnetic dataset corresponding to an archaeological site are used to report the results. [ABSTRACT FROM AUTHOR]

Iron ores and iron bloom slags from two iron archaeological sites (Chilgeumdong: 300–600 AD, Wanori: ∼20th century) as well as iron ores from six iron deposits in Chungju, South Korea, were examined to assess the provenance of the raw iron ores. Different ore mineralogy proves to be a useful tool in interpreting the ore provenance of samples from the iron archaeological sites, although limited by the simplicity of the assemblage. The application of Ca + Al + Mn vs. Ti + V diagram for classifying the genetic type of magnetite suggests that the iron ores of the iron archaeological sites may have originated from multiple deposits. Comparing the chondrite-normalized REE patterns and the correlation between Lan and Cen in iron ores and iron bloom slags aids in determining the provenance of samples from the iron archaeological sites. Despite notable deviations, the use of Pb-Sr isotope ratios as a means of identifying the origin of unprocessed iron ores proves to be a meaningful approach. Based on our findings, it appears that the iron ores discovered at archaeological sites were typically sourced from nearby iron deposits like Changdong, Yeonsudong, Daekyo, and possibly Manjeong. This preference for local sources as opposed to more distant ones, such as Obok and Yusang, seems to have remained a constant throughout various historical epochs, spanning from the Baekjae to the Joseon period. Overall, this study demonstrates the effectiveness of integrated interpretation of various complementary approaches, including ore petrography, trace and rare earth element geochemistry, and Pb-Sr isotope analysis, in determining the provenance of raw iron ores excavated from iron archaeological sites.

Recent salvage excavations at Ḥorvat Tevet in northern Israel revealed a cemetery consisting of at least 25 burials dated to the Iron I period (11th--10th centuries BCE). In this article, the burial practices employed in this cemetery are analyzed in order to shed light on the social complexity, economy, and funerary rituals of a rural community in the Jezreel Valley in the period between the collapse of Egyptian rule in Canaan and the formation of early monarchic Israel. Based on the finds in the graves and variations between graves, it is concluded that the site was home to a community characterized by minimal wealth accumulation, limited social division, and few long-distance trade contacts, though there are implications that the site had connections with the Beth-Shean Valley. This evidence is then contextualized in light of mortuary data from the Late Bronze II--Iron IIA Jezreel Valley in order to define aspects of continuity and change during the transition from Canaanite city-states to territorial polities.1 [ABSTRACT FROM AUTHOR]

Dental microwear is a common and wellestablished technique which allows the short-term reconstruction of the dietary behaviour in extinct and extant vertebrates, allowing inferences about daily, seasonal, or regional variations in diets. However, the use of this method may be limited because taphonomic processes can affect enamel surfaces and modify or obliterate dietary microwear features. Considering the substantial number of agents which can impact the archaeological record, dental microwear alteration processes are poorly known, producing a potential bias in dietary interpretations. In this study, the effect of trampling on dental occlusal surfaces, one of the most common processes recorded in archaeological assemblages, has been experimentally investigated for the first time. The results allowed us to (1) distinguish taphonomic and dietary marks; (2) assess the impacts of trampling on occlusal surfaces; and (3) infer the agents which modified the dental microwear from the teeth obtained from the archaeological sites. The importance of this work lies in the specific guidelines it offers to discriminate trampling marks from microwear features, improving the reliability of dietary interpretations.

This paper aims to characterise the modifications caused by the Pampas fox (Lycalopex gymnocercus) to the bones and teeth of its prey in the Espinal and Dry Chaco environments, in central Argentina. Plant remains, invertebrate remains, and vertebrate bones and teeth were recovered from a set of more than 180 faeces. From an actualistic perspective, we evaluated the taphonomic signature of this predator in the remains of snakes, birds and mammals recovered in its faeces. We achieved a high rate of taxonomical identification and recovered remains of exotic and native fauna, such as Ovis aries and Lagostomus maximus, respectively. The most remarkable aspects recorded in this taphonomic study were a high frequency of breakage, a low frequency of tooth marks (only observed in large prey), and a high frequency and intensity of digestion damage. The information generated in this study contributes to the evaluations of accumulating agents in archaeological and palaeontological sites of South America. [ABSTRACT FROM AUTHOR]

Lithic artifacts are some of the most common and numerous remains recovered from paleolithic archaeological sites. However, these materials can undergo multiple post‐depositional alterations after their introduction into the archaeological record. Due to the high quantity of lithic remains recovered, a quick, flexible, and effective method for identifying degrees of alteration on the surface of lithic implements is highly desirable. The present study examines the use of gray level images to obtain quantitative data from the surface of flint artifacts and determine whether these images can detect the presence of post‐depositional alterations. An experimental collection of flints was subjected to sequential episodes of rounding in a tumbling machine. After each episode, photographs were taken with a microscope, resulting in quantitative surface values using gray level values. The quantitative surface values were used as variables in machine learning models to determine time of exposure and the most salient variables for discrimination. Our results indicate that the extraction of metrics from gray level images successfully capture changes in the surface of flint artifacts caused by post‐depositional processes. Additional results provide insight into which areas to sample when seeking post‐depositional alterations and underscore the importance of particle size in the generation of alterations.

The manufacturing and corrosion properties of metal artefacts are significant for archaeologists and conservators. In this study, non-destructive neutron-based techniques are applied on ancient copper-iron arrows. The archaeological samples were excavated from a Western Han tomb (202 BC - AD 8) near the Han Chang'an city site (the capital of Western Han dynasty) in China. This is the first time that the combination of neutron resonance capture analysis, neutron diffraction, neutron tomography, and Raman spectroscopy has been used in Chinese cultural heritage to obtain useful information about the arrows. The results indicate that one arrowhead is made of low-Sn, high-Pb bronze, while the other is composed of high-Sn, low-Pb bronze. These analyses also reveal the production method of these arrows, with the iron tangs likely being cast first and then connected to bronze arrowheads through casting. Furthermore, due to the variations in materials used, certain parts of the arrows were more susceptible to corrosion than others; specifically, those made of pure iron were more prone to corrosion than their bronze counterparts. Additionally, it is confirmed that the iron inside the arrowhead corroded less than the visible iron tang at its base. The corrosion products include cuprite, goethite, hematite, magnetite, cerussite, azurite, malachite and lepidocrocite. These findings are highly beneficial for understanding the making techniques, as well as conservation state and corrosion products associated with archaeological arrows. [ABSTRACT FROM AUTHOR]

This paper offers an analysis of a group of glazed ceramics that comes from El Tolmo de Minateda site and have been dated in the second half of the ninth century and beginning of the tenth century, before the proclamation of the Umayyad Caliphate by Abderraman III (929 CE). Three technological groups have been distinguished: transparent glazes of one or two colours, transparent polychrome glazes (represented by two pieces) and opaque polychrome glazes (represented by two ceramics) studied by SEM-EDS analysis. After the study, different al-Andalus glaze workshops have been identified as providers of glazed ware to El Tolmo de Minateda site. The initial hypothesis was that the ware consumed in El Tolmo was manufactured in Pechina, the closest early production centre. However, after the archaeometric analysis, it has been discarded, and all the indications of this study seem to point to Córdoba as a significant supplier. The data of this study provides a new perspective on how the internal regional distribution and marketing of goods took place in Al-Andalus during the late Emiral period (c. 875–929 CE), a subject that has yet to be explored.

Preservation strategies at earthen archaeological sites are challenging to develop and maintain in the long term. Environmental fluctuations, anthropogenic interference, and pedological composition are only a few factors that can impact deterioration pathways. Owing to these complexities, there will never be a one-size-fits-all strategy for preserving earthen sites. However, archaeological spoil—or backdirt—can be employed to mitigate many of these challenges. Utilizing illustrative case studies at the earthen sites of Çatalhöyük, Turkey, and Vésztő-Mágor, Hungary, the authors present the use of backdirt as a sustainable, structurally supportive, contextually sympathetic, and visually congruent material for earthen site conservation. Matters of authenticity, ethical mandates, and social benefits of its use are also considered, as are its limitations. [ABSTRACT FROM AUTHOR]

In the United States, many archaeological excavations focus on precontact era Native American sites, and for the majority of American archaeology's existence, these have included a vast number of burial and sacred sites. When the human remains of Native American Ancestors, or remnants of sacred and ceremonial objects, are found, what implications does this have for the soil in which they rested? In addition to exploring questions regarding how backdirt is defined and assessed, we consider how backdirt may be interpreted as ecofact, as material culture, and even as NAGPRA-eligible funerary material or human remains. We hope to demonstrate that backdirt, as an example of some of the most insignificant archaeological material, poses interesting questions relating to interpretations of context, as well as consultation and collaboration with Indigenous communities.

Within the social, religious, and political context of present-day Jerusalem, soil is meaningful and marketable. This is evident in the Temple Mount Sifting Project, an archaeological tourist venture in occupied East Jerusalem. There, for almost two decades, archaeologists and many thousands of visitors have sieved through tons of earth—construction debris from building works on the Temple Mount/Haram al-Sharif that were undertaken without archaeological supervision. The Sifting Project has recovered thousands of finds and, yet, come under scrutiny from an archaeological practice point of view, particularly, because the material is out of context. Even though the debris itself is treated and presented as archaeological soil, "backdirt," it does not actually derive from a controlled excavation. How, then, is the material different from construction debris from other building sites where it would be treated as modern waste, rather than a gateway to the past? Within the soil the Sifting Project is concerned with, the worlds of archaeology, religion, and politics collide. This contribution examines the concept of backdirt within the contexts of archaeological practice, politics, and the heritage industry in occupied East Jerusalem. [ABSTRACT FROM AUTHOR]

Within an archaeology of the contemporary, sites and material remains of the Second World War have in recent years been set more prominently on the agenda of European heritage archaeology. This article presents observations made during archaeological site monitoring of the conversion and remediation of a former WWII military base in Germany. In the course of the project, the sensitivity of the site and its find material against the backdrop of the German history of World War II had to be constantly assessed. Archaeological methods and practices had to be adapted to the specific requirements of the site. Conflicting agendas of various actors and stakeholders involved had to be evaluated, as well as the risks posed by the site's contamination with unexploded ordnance. Indeed, the backdirt itself, just like the find material it contained, turned out to be a contested and hazardous entity. [ABSTRACT FROM AUTHOR]

According to the convergence confinement theory, it is an effective measure to control the large deformation of high ground stress in fractured soft rock tunnels by using yielding support. The yielding support can be classified as either radial or circumferential yielding support. Circumferential yielding support is achieved by transforming radial displacement into circumferential tangential closure without compromising the support capacity of the primary lining support structure. Based on this, and inspired by the design principle of dampers, a yielding support structure system with spring damping elements as its core was developed, based on the connection characteristics of steel arches in highway tunnel, which can provide increasing support resistance in the yielding deformation section. Then the mechanical properties of spring damping elements were obtained through indoor axial pressure and flexural tests. In addition, according to these results with numerical calculations, the yielding support structure system with embedded spring damping elements can reduce the internal force of the support structure by approximately 10% and increase the area of the plastic zone of the surrounding rock by 11.23%, which can fully utilize the self-bearing capacity of surrounding rock and verify the effectiveness of circumferential yielding support. Finally, the spring damping support structure system was designed with reference to the construction process of the tunnel excavated by drilling and blasting method, and the transformation of the spring damping element to spring damping support structure was achieved. Based on field test results, surrounding ground pressure for the yielding support optimization scheme was reduced by 40% and more evenly distributed, resulting in the successful application and a reduction in the construction cost of large deformation tunnels in soft rock.

The stability analysis of a deep buried tunnel subjected to dynamic disturbance is an important issue. In this study, the transient response has been obtained by establishing a water-rich tunnel model considering excavation damage zone (EDZ). Based on Biot's two-phase dynamic theory and wave function expansion method, the analytical solution of dynamic response around the water-rich tunnel containing EDZ subjected to P wave is derived. Moreover, Fourier transform and Duhamel's integral technique is introduced to calculate the transient response, and the equivalent blasting curve is adopted to input excitation function. The dimensionless parameters thickness N and shear modulus ratio μ are defined to characterize the degree of damage in the surrounding rock, investigating the influencing factors, such as the parameters and the incident source frequencies. The results indicate that the dynamic stress concentration factor (DSCF) gradually decreases as the dimensionless parameters increase. Additionally, it is observed that the DSCF is more sensitive to changes in the thickness parameter N. Finally, the influence of the waveform parameters has been taken into account in the analysis of transient response, and the stress state and transfer process in each time stage of the EDZ are analyzed. This study establishes a theoretical foundation for comprehending the mechanical behavior and support design considerations associated with a deep-buried water-rich tunnel containing EDZ.

A novel meta steel with negative Poisson's ratio effect (termed as micro-NPR steel) is developed for rock support in deep underground engineering. It possesses high strength, high ductility, and high energy absorption characteristics. In this paper, static tension and modified dynamic drop hammer tests are performed on this novel material to investigate its mechanical properties first. Then based on this material, a new generation of micro-NPR anchor cable is developed and applied in field tests subjected to blasting dynamic loads. The results of laboratory tests reveal that the ultimate elongation of micro-NPR steel under dynamic impacts is more than 30% and it is over 1.5 times that of Q235; the plastic and total energy absorption of micro-NPR are both significantly higher than that of Q235. Field test indicates the fine controlling effect of micro-NPR anchor cable on surrounding rock mass under dynamic loads. Axial force confirms that micro-NPR cables can distribute and absorb the dynamic energy uniformly around the supported rock when subjected to dynamic disturbance, avoiding local failure induced by excessive stress concentration. The excavation compensation principle and energy-absorbing characteristics are used to explain the support mechanisms. Thus, micro-NPR material and anchor cable can control and prevent dynamic disasters in deep underground engineering effectively. [ABSTRACT FROM AUTHOR]

Red tourism is a distinctive form of tourism in China. Its network attention serves as a typical indicator to measure the level of promotion and publicity for red tourism, as well as an important reflection of its influence. Understanding the network structure of red tourism is of significant importance for optimizing the spatial pattern of tourism and promoting the development of the tourism industry. Based on this, this study takes the classic red tourism attractions in Shaanxi province, China as an example and constructs a multi-source data network attention evaluation index. Additionally, it employs social network theory to explore the network attention and tourist flow characteristics of the case study area. Research shows that: (1) Overall, the network attention to case-based destinations is relatively low, and there are significant differences in network attention among different attractions. Spatially, the distribution of network attention is uneven. This is manifested by higher network attention to attractions in Yan'an city and lower network attention to attractions in other regions. (2) There are differences in the network attention of different types of attractions. High-level attractions have a higher level of online attention, while low-level attractions have a lower level of network attention. Additionally, archaeological sites tend to receive a higher level of online attention. (3) The network density of tourist flow is low, and the tourism connections between nodes are not closely linked. The linkage between core nodes and edge nodes in tourism is poor. Developed tourism routes only exist in core nodes. (4) Nodes such as Zaoyuan revolution site, Yangjialing revolution site, and Wangjiaping revolution site have a significant influence in the network structure. In addition, the integration and development between red nodes and non-red nodes have been achieved. (5) There is a correlation between network attention and tourist flow, as well as a 'misplacement' feature. Based on the characteristics of attractions, they can be divided into four types: bright-star attractions, cash-cow attractions, thin-dog attractions, and question attractions. Based on the above conclusions, this study proposes targeted development recommendations. [ABSTRACT FROM AUTHOR]

Brazilian coastal archaeology is renowned for its numerous and large shellmounds (sambaquis), which had been continuously occupied from at least 8000 to 1000 years cal BP. However, changes in their structure and material culture in the late Holocene have led to different hypotheses concerning their ecological and cultural changes. The archaeological site Galheta IV (ca. 1300 to 500 years cal BP) offers new insights into the complexity of the late coastal occupation in southern Brazil. Our attempt was to determine whether Galheta IV can be classified as a sambaqui site, or if it belongs to a Southern proto-Jê settlement. Here, we reassessed Galheta's collections and applied a multi-proxy approach using: new 14C dates, zooarchaeology, δ13C and δ15N isotopes in bulk collagen and 87Sr/86Srenamel isotopic ratios from eight human individuals, ceramics analysis, and FTIR. The results indicate an intense exploitation of marine resources, with an area designated for processing animals located at the opposite side of the funerary areas. Bone tools and specific species of animals were found as burial accompaniments. No evidence of human cremations was detected. 87Sr/86Sr results indicate that the eight human individuals always lived on the coast, and did not come from the inland. The pottery analysis confirms the association with Itararé-Taquara, but contrary to what was assumed by previous studies, the pottery seems related to other coastal sites, and not to the highlands. In light of these findings, we propose that Galheta IV can be considered a funerary mound resulting from long and continuous interactions between shellmound and Southern proto-Jê populations. This study not only enhances our understanding of the late coastal occupation dynamics in southern Brazil but also underscores its importance in reshaping current interpretations of shellmound cultural changes over time.

The bronze mou was an important artifact commonly used in the Ba-Shu region (now in Chongqing and Sichuan Province) during the Spring and Autumn Period and the Han Dynasty. Although extensive archaeological study of the bronze mou has been conducted, scientific analysis of the bronze mou has been limited, and no organic residue analysis has been performed on the bronze mou. In this study, four bronze mous dated to the Han dynasty (206 BC–220 AD) with organic residues unearthed in three archaeological sites in Wushan, Chongqing, were selected for analysis by portable X-ray fluorescent spectrometer (P-XRF) and liquid chromatograph-tandem mass spectrometry (LC/MS/MS). The results of the alloy composition indicated that all the samples are copper-tin-lead ternary alloys. The proteomic analysis results confirmed that the bronze mou had been used as cooking utensils or containers. At the Tuchengpo Cemetery, soybeans were found in both bronze mou M32:27 and M38:39, and vigna was discovered in M32:27. No useful protein was discovered in the bronze mou from the Shennvmiao Cemetery. Proteins of ginkgo and chicken were found in M16:12 at the Gaotangguan Cemetery. The discovery indicated that residents in Wushan, Chongqing, had access to a diverse range of food sources around 2000 years ago. Furthermore, this study demonstrates that proteomic analysis is highly effective in studying archaeological organic residues. [ABSTRACT FROM AUTHOR]

Point Pattern Analysis (PPA) has gained momentum in archaeological research, particularly in site distribution pattern recognition compared to supra-regional environmental variables. While PPA is now a statistically well-established method, most of the data necessary for the analyses are not freely accessible, complicating reproducibility and transparency. In this article, we present a fully reproducible methodical framework to PPA using an open access database of archaeological sites located in south-west Germany and open source explanatory covariates to understand site location processes and patterning. The workflow and research question are tailored to a regional case study, but the code underlying the analysis is provided as an R Markdown file and can be adjusted and manipulated to fit any archaeological database across the globe. The Early Iron Age north of the Alps and particularly in south-west Germany is marked by numerous social and cultural changes that reflect the use and inhabitation of the landscape. In this work we show that the use of quantitative methods in the study of site distribution processes is essential for a more complete understanding of archaeological and environmental dynamics. Furthermore, the use of a completely transparent and easily adaptable approach can fuel the understanding of large-scale site location preferences and catchment compositions in archaeological, geographical and ecological research.
