Optimal Bayesian chronological modeling for high resolution chronology for the Middle Jomon of Kanto region (Honshu Island, Japan) approaching a generational scale
In recent years, the increasing accumulation of radiocarbon dating data in Jomon research has progressed, creating a foundation for more detailed chronological estimates of the Jomon period’s high-resolution typo-chronology. However, there remains a gap between relative chronologies based on typology and radiocarbon data. A key issue arises from discrepancies between the concept of keishiki (“type” in Japanese) as a time unit of relative chronolo…
Human femur and tibia retain primary lamellar bone formed during growth
Laser Ablation System With a Diode Laser for Ams 14 C Measurement of Organic Materials
We constructed a laser ablation (LA) system using a diode laser for the accelerator mass spectrometry radiocarbon (AMS 14 C) measurement of organic materials. The system could extract adequate CO 2 to analyze small masses (0.1 mg C) at a resolution of 250 μm by a 5.5 W diode laser. The LA system was assessed using standard materials (IAEA-C1, IAEA-C2, IAEA-C3, IAEA-C6, and Ox II) and applied to natural tree ring samples. For the LA sampling of or…
Beppu Bay, Japan, as a candidate Global boundary Stratotype Section and Point for the Anthropocene series
For assessment of the potential of the Beppu Bay sediments as a Global boundary Stratotype Section and Point (GSSP) candidate for the Anthropocene, we have integrated datasets of 99 proxies. The datasets for the sequences date back 100 years for most proxy records and 1300 years for several records. The cumulative number of occurrences of the anthropogenic fingerprint reveal unprecedented increases above the base of the 1953 flood layer at 64.6 c…
Aleutian Low variability for the last 7500 years and its relation to the Westerly Jet
The Aleutian Low (AL) is one of the major atmospheric systems that determines environmental conditions during winter in the North Pacific Ocean, with impacts that affect the climates of both Asia and North America from mid- to high latitudes. However, the multi-centennial and longer scale behavior of the AL during the Holocene is not fully understood. In this study, AL variability since 7.5 ka was examined by applying the principal component anal…

How does area-level deprivation depress an individual’s self-rated health and life satisfaction? Evidence from a nationwide population-based survey in Japan
Results showed that area-level deprivation modestly decreased an individual's general health conditions and subjective well-being, underscoring the need for public health policies to improve area-level socioeconomic conditions
Lithic Technology and Chronology of Initial Upper Paleolithic Assemblages at Tor Fawaz, Southern Jordan
The Initial Upper Paleolithic (IUP) is a key chrono-cultural concept in our understanding of the cultural and population dynamics at the transition from the Middle Paleolithic to Upper Paleolithic period. This paper presents technological and chronological analyses of lithic assemblages from a rockshelter site at Tor Fawaz in the Jebel Qalkha area, southern Jordan, to provide accurate dating and detailed recognition of the IUP variability in the …
Emergence and Development of Pottery in the Andean Early Formative Period
This article presents a high-resolution chronology of Wairajirca pottery in the Huánuco basin, which has been identified as a frontier region between the Andean highlands and the Amazonian rain forests: its pottery is known for having mixed features from both areas. However, the lack of fine-grained pottery and radiocarbon datasets has handicapped comparative studies' attempts to track in detail its early development process. Our new high-resolut…

Carbon and nitrogen isotope analysis and radiocarbon dating on the Initial Jomon human skeletons from Iwashita Cave, Sasebo City, Nagasaki, Japan
Bone collagen was extracted from a series of Jomon skeletons from Iwashita Cave in Sasebo City, Nagasaki, Japan, which were excavated in 1964-1966 seasons. The radiocarbon dates on 5 skeletons from Layer V showed calibrated dates between 9000 and 10000 cal B.P. corresponding to the Initial (Earliest) Jomon period
From cradle to grave
The life history of a female individual skeleton (ST61) from the Edo period (AD 1603–1868) was investigated by using multi-tissue and multi-isotope analyses. Her gravestone and historical documents revealed that ST61 was a grandmother of a chief retainer of the Akashi clan who died in 1732 aged 77 years. Radiocarbon and sulfur stable isotope analyses indicated that the contribution of marine foods to the ST61 diet was relatively low (17.2% protei…
Analyzing the Final Jomon human remains from the Nonomae shellmound, Ofunato City, Iwate Prefecture
岩手県大船渡市野々前貝塚から出土した縄文時代晩期の熟年男性1体(1号),胎児ないし新生児1体(2号),壮年後半から熟年前半の女性1体(3号),熟年女性1体(4号),3歳程度の幼児1体(5号)の計5体について,形態人類学的および理化学的分析を実施した。人骨の年代は放射性炭素年代測定により3150~3000年前(cal BP)と推定された。形態学的検討およびDNA分析の双方から,野々前貝塚人骨が縄文時代人に一般的な形質を有することが明らかとなった。ミトコンドリアDNAのハプログループが判明した3体(1号N9b1,4号N9b*,5号M7a2)に母系の血縁関係は認められなかった。特筆すべき古病理学的所見として,出土成人3体全ての外耳道に明瞭な外耳道骨腫が確認された。これは,野々前貝塚の人々が水中(潜水)ないし水面域での漁撈活動に従事していた可能性を示唆するものである。炭素・窒素同位体比の分析では海産物を多く摂取していた食性が提示されており,外耳道骨腫の多発との関連がうかがわれた。また,出土成人3…
Variability in Early Ahmarian lithic technology and its implications for the model of a Levantine origin of the Protoaurignacian
This paper re-examines lithic technological variability of the Early Ahmarian, one of the early Upper Palaeolithic cultural entities in the Levant, which has often been regarded as a precursor of the Protoaurignacian (the early Upper Palaeolithic in Europe) in arguments for the occurrence of a cultural spread in association with the dispersal of Homo sapiens from the Levant to Europe. Using quantitative data on several lithic techno-typological a…
Assessing the Chronology and Rewrapping of Funerary Bundles at the Prehispanic Religious Center of Pachacamac, Peru
Over 30 funerary bundles were excavated in 2005 from a large chamber tomb at the prehispanic religious center of Pachacamac on the central coast of Peru. The largest and most elaborate bundle was found in the innermost part of the tomb, tightly surrounded by other bundles. We hypothesized that this bundle contained the deceased leader of a social group whose members collectively cared for their ancestor's bundle (for example, by rewrapping it) an…
An investigation of social factors related to online mentalizing in a human‐robot competitive game
“Mentalizing” is the ability to attribute mental states to other agents. The lack of online mentalizing, which is required in actual social contexts, may cause serious social disorders such as autism. However, the mechanism of online mentalizing is still unclear. In this study, we found that behavioral entropy (which indicates the randomness of decision making) was an efficient behavioral index for online mentalizing in a human‐human competitive …
