INCISED SLIPWARE PRODUCTION AT CASTELFIORENTINO (FLORENCE): THE ‘VIA BERTINI’ SITE (15TH–17TH CENTURIES)*

This study deals with the physical–chemical and mineralogical–petrographic investigations (OM, SEM–EDS, EPMA, ICP, XRpD, Mössbauer and IR) conducted on first‐ and second‐firing wasters belonging to two types of incised slipware (sgraffito), manufactured at Castelfiorentino between the late 15th and the early 17th centuries. Raw materials, colouring agents and firing products were analysed in order to establish the production technology of the ceramic coatings, by means of detailed microtextural and chemical investigations. The pottery underwent two firing processes: the firing of the white slip‐coated ceramic body and a further firing after application of the glaze. The homogeneity of the raw materials, white slip and glaze is remarkable, and demonstrates the use of well‐established recipes with a constant supply of raw materials from the same places. Highly efficient kiln management during both firings is revealed by body–glaze interface reactions.     

18-20世纪人体测量史:理论、研究方法、史料以及最初的结果

男性身高的变化能够反映出俄国人口福利状况的变化。1700—1980年,俄国男性士兵身高资料及与之相应的生活状况和福利评估大体分为9个阶段,人的生活状况提高、降低和稳定阶段分别为150、100和30年,280年间男女的身高分别增加了10—11厘米。每逢战争和激烈改革时期,赋税增加和连年歉收,人口的身高、生活状况和福利无不下降;而每逢战争过后,政策得当,社会稳定,风调雨顺之时,人口的身高、生活状况和福利均提高。总之,18世纪俄国民众的整体生活水平下降,而19—20世纪俄国,特别是1921—1980年苏联时期的人口福利提高。这些结论察前人所未察,发他人所未发。     

Is there a Rosenberg school?

Since his first book The Cholera Years appeared in 1962, Charles Rosenberg has had an enormous influence on the history of medicine. Not the least of that influence has been exercised through his role as a graduate teacher, advisor, and mentor. This article compares Rosenberg's work with that of his students, to see if there is such a historiographic identity as the "Rosenberg School." The authors, two Rosenberg students from different generations, conclude that there is not such a school, at least in the classic sense of the term. Yet they argue that certain common assumptions, or "Rosenberg Rules," have been passed on from Rosenberg to the other scholars he has influenced. They also discuss the challenges they have encountered in applying Charles's conceptual framework, worked out primarily in pre-1920 terms, to the late twentieth-century history of American medicine.     

Mortality date estimation using fetal pronghorn remains

Pronghorn (Antilocapra americana) fetal remains are sometimes recovered from archaeological contexts. Pronghorn have consistent reproductive schedules so their remains may provide information on seasonality of site occupation and number of mortality events. To investigate the reliability of fetal remains for seasonality and mortality event assessment, bone size and tooth eruption were measured in a sample of modern fetal pronghorn remains with known mortality dates. Results indicate a strong correlation between bone size and mortality date, but no significant correlation between tooth eruption level and mortality date. Fetal bone size was used to estimate a late April or early May mortality date at both the Oyster Ridge (48UT35) and Trappers Point (48SU1006) archaeological sites. The number of mortality events at Trappers Point was also investigated. Copyright © 2007 John Wiley & Sons, Ltd.     

The application of structured‐light illumination microscopy to hydrocarbon‐bearing fluid inclusions

Structured‐light illumination (SLI)‐based microscopy offers geologists a new perspective for screening of hydrocarbon‐bearing (HCFI) and small aqueous fluid inclusion (AFI) assemblages. This optical‐sectioning technique provides rapid, confocal‐like imaging, using relatively simple and inexpensive instrumentation. The 3D fluorescent images of HCFI planes and large single HCFIs permit the visualization of the relationships between HCFI assemblages, examination of HCFI morphology, and volume estimates of the fluorescent components within HCFIs. By the use of normal white light illumination, SLI image capture, and varying acquisition time it is also possible to image AFI because of the random movements of vapour bubbles within the inclusions. This allows the near‐simultaneous visualization of hydrocarbon and AFI which is of significant importance for the study of sedimentary basins and petroleum reservoirs. SLI is a unique and accessible 3D petrographic tool, with practical advantages over conventional epifluorescence and confocal laser scanning microscopy.     

The pearls and pitfalls of skull trephination as described in the Hippocratic treatise "On Head Wounds"

The purpose of our current study is to describe the guidelines regarding trephination as suggested in the Hippocratic writer's book, "Peri ton en cephali traumaton" ("On Head Wounds"). The ancient Greek text was reviewed as well as two English translations. The Hippocratic author described the indications, timing, and techniques of trephination for patients with head injury. He emphasized that attention should be paid to the details of the employed technique. He also commented on the difference of skull thickness at different anatomical sites and also between different age groups. The Hippocratic recommendations provided details for the performance of trephination by the ancient Greek physicians that are still considered important in modern neurosurgery.     

Application of Landsat satellite imagery to monitor land‐cover changes at the Athabasca Oil Sands,Alberta, Canada

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.     

Laying it down in stone: delimiting and demarcating Iraq's boundaries by mixed international commission

Mixed international commissions have been centrally involved in shaping the outer margins of the state territory of Iraq over the last century and a half. Laborious Anglo-Russian efforts to narrow the traditional Perso-Ottoman frontier in the seventy-year period before the Great War contrasted with the League of Nations' ostensibly speedy treatment of Iraq's more arbitrary northern and north-western territorial limits in the early inter-war years. Most recently, a team appointed by the UN Secretary-General finalised definition of Iraq's international boundaries with Kuwait when the emirate was liberated from Iraqi occupation in the spring of 1991. This article scrutinises the role played by these bodies in the boundary evolutionary process from a review of their primary records. It highlights the fact that the evolution of Iraq's (and those of its Ottoman forbears) international boundaries to the east, north and west was rarely straightforward and reflected both regional considerations and imperial contexts. The problem of reconciling inadequate textual definitions with features on the ground has been a constant phenomenon. Deciding whether commissions actually delimited or demarcated territory was as valid a question following the UN's Iraq–Kuwait settlement as in the mid-nineteenth century. Whether many historical treaty delimitations were ever designed to be anything more than territorial allocations is another theme explored in this article.     

The consilience of historical and isotopic approaches in reconstructing the medieval Mediterranean diet

During the Middle Ages, the economies of Europe, the religious directives involving dietary requirements, and the general human subsistence base were transformed. These complicated and intertwined issues are starkly revealed in an isotopic study of two inland Italian human populations that are separated by approximately 850 years in time. Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopic values observed in human dentin and bone collagen from the sites of early medieval Castro dei Volsci and late medieval Rome are consistent with diets that differed substantially. As the North Atlantic opened to fishing and food preservations methods improved, Mediterranean peoples increased their fish consumption dramatically, and in doing so, met the religious directives of the Catholic Church. By analyzing both teeth and bone collagen within individuals, long-term feeding behaviors are documented, and the utility of last erupted teeth collagen as sources of adult dietary information is established. This study offers the first physical evidence of this new economic reality linking the Atlantic and Mediterranean economies at the end of the Middle Ages.     

Ancient DNA in human bones from Neolithic and Bronze Age sites in Greece and Crete

Attempts were made to detect ancient DNA (aDNA) in samples of 88 human skeletons from eight Neolithic and Bronze Age sites in Greece and Crete. Ancient DNA was absent in specimens from Nea Nikomedia, Lerna, Karaviádena (Zakro), Antron Grave Circle A and Mycenae Grave Circle A. For each of three skeletons from Antron Grave Circle B that were sampled, polymerase chain reactions (PCRs) gave products for nuclear but not mitochondrial DNA, but amplicon yield was low and inconsistent with replicate PCRs failing to give reproducible results. With specimens from Mycenae Grave Circle B, evidence for mitochondrial aDNA was obtained for four of the 22 skeletons that were studied, and at Kouphovouno evidence for mitochondrial and/or nuclear aDNA was obtained with eight of the 20 skeletons that were examined. We conclude that, although aDNA might be present in some Eastern Mediterranean skeletons from later centuries of the Bronze Age, it is not commonly found in material from this period and is likely to be absent from older material.
