Glass Beads from 15th–17th Century CE Jar Burial Sites in Cambodia's Cardamom Mountains

A total of 74 glass beads, included as grave goods in 15th–17th century CE jar burials from Cambodia's Cardamom Mountains, were analysed using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS). Several glass types were identified, including two subtypes of high‐alumina mineral soda glass, and lead–potash glass. The final glass type represents a newly discovered and previously unidentified type of high‐alumina soda glass, with high magnesia (m‐Na–Al Mg>). This study represents the first glass data from the mid‐second millennium CE from Cambodia and sheds light on the multiple long‐distance maritime exchange networks in which the upland people buried in the jars were participating.     

Rock art on Socotra,Yemen: the discovery of a petroglyph site on the island's south coast.

Recent fieldwork on the south coast of the island of Socotra, Yemen, has revealed a hitherto unknown petroglyph site. This site represents the first rock art to have been recorded on the south coast, an area generally regarded as being unpopulated up until the recent past. The corpus of recorded petroglyphs includes feet, cupules, anthropomorphic figures and geometric motifs, whose designs parallel those from known rock‐art sites on the north coast. The importance of this site is that it provides us with the first glimpse into the religious and socio‐political lives of the inhabitants of the previously unknown southern half of Socotra. Placing these petroglyphs within the broader context of rock‐art studies on the island of Socotra has also allowed us to begin to disentangle the skewed view of Socotra's inhabitants.     

Fluid chemistry in the Solitaire and Dodo hydrothermal fields of the Central Indian Ridge

Fluid chemistry and microbial community patterns in chimney habitats were investigated in two hydrothermal fields located at the Central Indian Ridge. Endmember hydrothermal fluid of the Solitaire field, located ~3 km away from the spreading center, was characterized by moderately high temperature (307°C), Cl depletion (489 mm ), mildly acidic pH (≥4.40), and low metal concentrations (Fe ≤ 105 μm and Mn = 78 μm ). Chloride depletion indicates that the subseafloor source fluid had undergone phase separation at temperatures higher than ~390°C while the metal depletion was likely attributable to fluid alteration occurring at a venting temperature of around 307°C. These different temperature conditions suggested from fluid chemistry might be associated with an off‐spreading center location of the field that allows subseafloor fluid cooling prior to seafloor discharge. The microbial community in the chimney habitat seemed comparable to previously known patterns in typical basalt‐hosted hydrothermal systems. Endmember hydrothermal fluid of the Dodo field, standing on center of the spreading axis, was characterized by high H₂ concentration of 2.7 mm . The H₂ enrichment was likely attributable to fresh basalt–fluid interaction, as suggested by the nondeformed sheet lava flow expansion around the vents. Thermodynamic calculation of the reducing pyrite–pyrrhotite–magnetite (PPM) redox buffer indeed reproduced the H₂ enrichment. The quantitative cultivation test revealed that the microbial community associated with the hydrothermal fluid hosted abundant populations of (hyper)thermophilic hydrogenotrophic chemolithoautotrophs such as methanogens. The function of subseafloor hydrogenotrophic methanogenic populations dwelling around the H₂‐enriched hydrothermal fluid flows was also inferred from the ¹³C‐ and D‐depleted signature of CH₄ in the collected fluids. It was observed that the hydrothermal activity of the Dodo field had ceased until 2013.     

Purposeful commingling of adult and child cranial elements from the Chelechol ra Orrak Cemetery,Palau

Continued excavation in 2007 of the early (ca. 2000–3000 calBP) cemetery at Chelechol ra Orrak in Palau, Micronesia revealed the remains of at least six individuals, adding to a minimum number of at least 25 other mostly fragmented individuals recovered in previous years. Of particular interest was the discovery of two isolated adult partial crania one of which, when emptied of sandy matrix, was found to contain a complete child's frontal bone. Here we explore the possibility that the placement of the skulls, particularly the commingling of the adult and child cranial elements, was done purposefully and discuss its significance for early Pacific mortuary behaviours.

A Mississippian conflagration at East St. Louis and its political-historical implications

Abstract

A walled portion of the extensive Precolumbian civic-ceremonial precinct of East St. Louis, near present day St. Louis, Missouri, enclosed a cluster of as many as 100 small buildings or huts. The huts were associated with a walled ritual-residential zone or elite compound dating to the late Stirling phase (a.d. 1150–1200) and, importantly, were burned in a single conflagration. The burning of East St. Louis may have resulted from a ritual commemoration, an act of aggression, or an accidental fire; circumstantial evidence primarily supports the first scenario. With strongly diminished mound and architectural construction at the site in subsequent decades, and with the coeval disappearance of key ritual-residential buildings from the regional landscape after the burning, the ancient East St. Louis fire was part of a larger pattern of historical events that mark a downward turning point in the social and political history of Greater Cahokia.     

Palynological and Archaeological Evidence for Ritual Use of Wine in the Kura-Araxes Period at Aradetis Orgora (Georgia,Caucasus)

Pollen and non-pollen palynomorphs from two zoomorphic Kura-Araxes vessels (ca. 3000 b.c.) from Aradetis Orgora suggest they were utilized for the ritual consumption of wine and likely represent the beginning of the enduring tradition of animal-shaped wine-drinking containers in Georgia. This hypothesis is supported by archaeological and geoarchaeological data: they resemble later wine-containing vessels from Georgia and elsewhere and were found in a building whose context is suggestive of a small shrine. Their palynological spectra match those of present-day wine and wine containers of other periods. One of them was intact, with only a small access hole; consequently, its palynological spectrum can be utilized as a standard for determining the presence of wine in other archaeological vessels. Palynological analyses from different contexts of the Aradetis Orgora settlement and its cemetery (Doghlauri) yielded other significant results regarding the practice of viticulture and the cultural relevance of wine during the Kura-Araxes period.     

Revelation and Resolution: Religion as the Key to Cognition,Power, and History in Anthropology

Religion is often considered as key to interpreting human psychological and social processes. Yet, the notion that ritual performance and religious beliefs offer a transparent portal onto the inner workings of culture, power relations, historical change, and cognition are subject to critique. The political and psychological implications of ritual practice differ considerably from culture to culture and religion defies reduction to a single explanatory or etiological framework. Anthropologists best learn about emic and etic understandings of belief by interpreting the historically varied articulations of religious experience with other social domains.     

Undertaking a Dissertation from Start to Finish: The Process and Product

Advocates for using a geographic information system (GIS) in education assert that GIS improves student learning. However, studies to clarify the relationship between learning and using GIS are still needed. This study examines the effects of using Web-based GIS maps in place of paper maps on students' geography content knowledge and motivation (self-efficacy) when taking college-level introductory human geography (N = 171). Hierarchical regression analysis shows that using Web-based GIS is positively related to post-test self-efficacy and post-test geography content knowledge.     

北魏前期汉族士人的社会交往初探

在中国中古门阀政治的背景下,士人之间的社会交往对于维护和提升其政治地位具有重要作用。北魏前期的汉族士人虽然在政治上受到较大的限制,但他们仍然试图在现有政治状况之下,通过社会交往建立社会网络,从而形成相互间的身份认同并获得有效的政治资源。乡里社会是汉族士人展开社会交往的基础,他们也十分重视。随着仕宦于平城的汉族士人逐渐增多,平城就成了北魏前期汉族士人社会交往的中心。以崔浩为中心的社交网络和青齐地区的汉族士人的交往成了这一时期较为明显的两种社会交往形态。当然,汉族士人之间的社会交往往往受到政治的牵连。     

新郑铁岭墓地M1404、M1405发掘简报

新郑铁岭墓地M1404、M1405为东西向大墓,南北相距2米,均出土成套青铜礼器与陶器。铜器墓紧临,这在铁岭墓地还是首次出现。周围大中型墓葬,也多出土有成套的陶器。其北、其西40米开外的墓葬极少随葬器物,说明这一带可能为一个家族墓地。
