Neolithic cremation in south‐east Arabia: archaeological and anthropological observations at FAY‐NE10 in the Emirate of Sharjah (UAE)

Small fragments of cremated human bone, clearly representing numerous individuals, were found in a stratified Neolithic context in a small cave at Jebel Faya in the Central Region of the Emirate of Sharjah, United Arab Emirates. With radiocarbon dates between 6500 and 5800 cal BC, they are among the earliest well‐documented cases of cremations in south‐west Asia. Taxonomic identification of the small burned bone fragments is based on morphological and histological analysis. The deposits are to date the oldest human remains found in south‐east Arabia and represent a phase during the Middle Neolithic for which no other types of burials have yet been documented.     

U-series dating of soda straw stalactites from excavated deposits: method development and application to Blanche Cave, Naracoorte, South Australia

This study aimed to further test the method, reported by St Pierre et al. (2009), to develop robust chronologies of deposits in limestone caves through U/Th (Uranium/Thorium or U-Series) dating of soda straw stalactites. The chronology of fossil bearing deposits at Blanche Cave was further constrained with thermal ionisation mass spectrometry (TIMS) U/Th dating of 17 additional soda straw stalactite samples, and results were compared to recalibrated ¹⁴C ages of charcoal. The results support the assertion that soda straw stalactites can provide ages close to the time of sediment deposition and may be used as reliable chronological markers, particularly for periods reaching or beyond the radiocarbon dating limit. The application of an enhanced cleaning technique facilitated the reduction of detrital Th in samples, significantly increasing age accuracy and precision. Additionally U/Th age accuracy and precision was increased through the application of site-specific measured U/Th ratios to correct for the detrital ²³⁰Th component in samples.     

Public and Partisan Opinions of the Speaker of the House

Using polling data from 1982 to 2009, I develop a model of public opinion toward the Speaker of the House. I show that, in addition to economic and institutional factors, the speaker's ideology and events associated with the speaker's responsibilities in office affect the public's opinion toward this congressional leader. I also examine the partisan differences in the formation of public opinions about the speaker. I find that minority party partisans are more likely to have negative evaluations of the speaker when the speaker has more ideologically extreme views which lead to higher levels of polarization. In addition, members of different parties weigh economic and institutional factors differently in their evaluations of the speaker.     

THE “RUSSIFICATION” OF ETHNIC MINORITIES IN THE USSR

Among the avowed social policies of the Soviet Union are modernization and industrialization, which may be combined under the label of Sovietization, and the spread of Russian language and culture within the USSR, which may be termed Russianization. But there is also a third process at work in which non-Russians lose their ethnic identity in favor of identification with Russian culture. This process, which may be called "Russification," can be measured by the number of non-Russians who declare Russian to be their first language in the census. The authors use correlation analysis and principal components analysis to identify the factors that promote or hinder the Russification process.     

Expanding the utility of Uranium-series dating of speleothems for archaeological and palaeontological applications

Uranium-series (U-series) dating of speleothems is frequently used for palaeoclimate studies but its archaeological and palaeontological applications are limited to stratigraphically significant speleothem formations, such as flowstones, to provide maximum and minimum temporal points. This study targeted soda straw stalactites for U-series dating. In contrast to other speleothem formations, soda straw stalactites are fragile, have typically short life spans (usually only years but rarely up to a few hundred years) and are frequently incorporated into cave deposits. Results of thermal ionisation mass spectrometry (TIMS) U-series dating of soda straw stalactites from palaeontological excavations at Blanche Cave, South Australia, show that small, dense, clean straws tend to yield ages closest to the time of stratigraphic deposition. A correlation between soda straw U-series ages and radiocarbon ages of charcoal from the site is shown. Multiple soda straw age determinations for a single stratigraphic unit are required in order to verify age concordance. In conjunction with other dating methods, U-series dating of soda straw stalactites may help to significantly constrain the age of stratigraphic units and associated archaeological and palaeontological deposits in order to provide more robust chronologies. Here we advocate the collection of soda straw stalactites at future excavations of limestone cave sites.
