The relationship of bone mineral density and other growth parameters to stress indicators in a medieval juvenile population

In this study the radii of 34 juveniles from Wharram Percy, a British medieval site, were measured for bone mineral density (BMD) using dual energy X‐ray absorptiometry (DXA) in order to investigate evidence of stress including Harris lines, cribra orbitalia and deficient cortical index, which is usually attributed to poor nutrition. BMD measurements are used in modern children to assess growth and development and generally correlate with linear growth. Only rare chronic illnesses affect bone mineral accrual in children. Radiographs of the radii were examined to assess cortical index and of the femora and radii for Harris lines. The results indicate that BMD is well correlated with dental age and linear growth, but is poorly correlated with cortical index. The variability in cortical index indicates the influence of environmental factors. There is no relationship between BMD and the presence or absence of Harris lines or cribra orbitalia. Thus, despite obvious evidence of skeletal stress in this juvenile population, bone was not under‐mineralised and bone mineral accrual proceeded normally with growth. This reinforces the conclusion that cortical index is a more sensitive indicator of environmental stress than either Harris lines or cribra orbitalia, and may be compared with BMD measurements to assess the effect of stress on growth.

BIOARCHAEOLOGICAL ANALYSIS OF SUBSISTENCE AND HEALTH AT THE LAKE GEORGE SITE,MISSISSIPPI (22YZ557)

Abstract

Bioarchaeological investigations of subsistence and health were conducted on a skeletal population from the Lake George site (22YZ557), a large prehistoric settlement in the lower Yazoo basin of west-central Mississippi. Subsistence is inferred from oral health indicators (including dental caries, calculus, periodontal disease, abscesses, antemortem tooth loss, and macrowear) and stable carbon and nitrogen isotope ratios from bone collagen and apatite. Health is inferred from nonspecific indicators (including cranial porous lesions, enamel hypoplasias, and Harris lines). The sample includes 25 adults and 25 subadults, all of which date to the Coles Creek period (A.D. 700–1200). Frequencies of all pathological conditions are reported for the entire sample and divided by sex and age for adults. Results indicate a heavy pathology load at Lake George, but one that is not dissimilar to other Coles Creek populations. Isotope values indicate a diet that included primarily C3 plants (δ¹³C_Col = ?21.03‰, δ¹³C_Ap-Diet = ?22.06) and terrestrial protein (δ¹⁵N = 9.72‰). The sources of nonspecific pathologies are attributed to stressors associated with increasing population density and cultural complexity that occurred during the Coles Creek period.     

Scottish fishing at the start of the millennium: Towards sustainability under ecological and economic pressure

Development proposals in areas with renowned natural heritage frequently stir up environmental controversy. In recent years, the Scottish Highlands and Islands have seen two particularly high‐profile conflicts of this type: the proposals for an aggregates superquarry on Harris and for a funicular mountain railway in the Cairngorm ski area. The first was turned down, the second has gone ahead. These showdowns between development and conservation interests shared characteristics which typify environmental conflicts: tension between ‘insiders’ and ‘outsiders’, polarised viewpoints, contrasting interpretations of sustainable development, criticism of the planning system and disagreement over decision making procedures. This paper explores these themes through detailed considerations of the two specific debates and of the arguments that were fielded to support or oppose the projects.     

Diet and mobility in Middle Archaic Florida: stable isotopic and faunal evidence from the Harris Creek archaeological site (8Vo24), Tick Island

We explore diet and mobility in Middle Archaic Florida using human burials and faunal remains from the Harris Creek archaeological site (8Vo24) on Tick Island. We conducted stable carbon and oxygen isotopic (δ¹³C, δ¹⁸O) analyses of 50 human enamel samples and strontium isotopic (⁸⁷Sr/⁸⁶Sr) analysis of a subset of 10. Most individuals (46/50) subsisted on local freshwater and terrestrial resources, with relatively depleted δ¹³C values (C₃) and δ¹⁸O values matching those of central and north Florida water resources within the St. Johns River valley. Eight of 10 burials have local, within valley ⁸⁷Sr/⁸⁶Sr values. Two human burials yield marine δ¹³C and ⁸⁷Sr/⁸⁶Sr values, which we interpret as evidence for across valley movement from the coast. Another two individuals show depleted δ¹⁸O values, likely obtained from northern rivers. We also identified potential food resources and non-local foods from the Harris Creek faunal assemblage. We found six species with estuarine and marine habitat preferences; two of which, whelk and quahog, indicate that people of Harris Creek traveled to or traded with coastal areas.     

J. Casely Hayford’s Social Imaginary of “Church Universal” in William Waddy Harris the West African Reformer: The Man and His Message (1915)

A close reading of J. Casely Hayford’s tract William Waddy Harris The West African Reformer: The Man and His Message (1915) provides insight into the political considerations accounted for in writing histories of world Christianity during the colonial period. Hayford centres Africa and William Waddé Harris in a social imaginary that critiques Europe as the exclusive centre of religious reform and renewal. I argue that Hayford employs methods of analysis, rhetorical devices, and literary interlocutors that reflect his African positionality within the early colonial period. To this end, I argue that Hayford’s tract reconceives a history of world Christianity that predates the organised study of missions, ecumenics, and world religions. Without dismissing the contributions of these fields to the emergent field of World Christianity, Hayford’s colonial positionality lends him a contrasting and precarious double consciousness with which to the re-imagine a discourse of universal Christianity through and out of West Africa.     

Cortical epileptogenesis and David Ferrier

There was an increasing medical interest in the localization of representation of function in the cerebral cortex after Broca in 1861 identified a cortical area that appeared responsible for expressive speech. By the late 1860s, John Hughlings Jackson—based on clinico-pathological correlations mainly in persons with focal motor seizures—had reasoned that contralateral somatic motor function was represented in another area of the cortex. This localization was supported by Fritsch and Hitzig (1870) in experimental cortical stimulation studies in dogs. These authors also reported producing events resembling contralateral motor convulsing in their animals. Their work, and Jackson’s ideas, prompted David Ferrier, in Great Britain, to begin a program of cerebral cortical stimulation studies in various vertebrate species, trying to locate cortical sites of representation of functions other than expressive speech and motor activity. In his initial report of his investigations (1873), he noted that appropriately sited Faradic stimulation evoked immediate or delayed contralateral focal motor seizures, some of which evolved into generalized convulsions. On this basis he reasoned that focal motor and generalized seizures were expressions of the same disorder; that nearly all epilepsies originated in the cerebral cortex and not in the lower brain stem, as hitherto thought; and that the clinical pattern of epileptic seizure phenomenology depended on the function of the cortical site of origin and the extent and direction of spread of seizure activity in the brain. He not only provided experimental verification for Jackson’s reasoning about epileptic seizure mechanisms but expressed the ideas a good deal more clearly than Jackson ever managed to do. Ferrier’s achievement in this regard has tended to escape notice, lost sight of because of the great importance of his investigations into localization of cerebral function.     

An investigation of cortical bone loss and fracture patterns in the neolithic community of Çatalhöyük,Turkey using metacarpal radiogrammetry

Bioarchaeologists have conducted numerous studies on human skeletal remains using metacarpal cortical bone radiogrammetry. This method allows cortical thickness of the second metacarpal to be quantified. As a sensitive index of bone health metacarpal cortical thickness is evaluated in the context of functional adaptations, growth, ageing and bone loss in osteoporosis, as well as used as a reliable indicator of fracture risk. The focus of this study is an examination of the widely used calculation that expresses second metacarpal cortical bone values, followed by an examination of age and sex-related patterns of cortical bone loss and skeletal fragility fracture in a Neolithic archaeological skeletal sample from Çatalhöyük, Turkey. Using metacarpal radiogrammetry, 49 adult metacarpals (f = 27 m = 22) were examined. Data were collected for size variables, length (L) and total bone width (TW) as well as quantity variables, medullary width (MW) and cortical thickness (CT). These parameters were then used to calculate the widely used cortical index (CI) and two new indices expressing medullary width and cortical bone thickness in relation to length (medullary width index, MWI and cortical thickness index, CTI). The ratios were then used to explore age- and sex-related cortical bone loss and fragility fracture patterns amongst the inhabitants of Çatalhöyük. Çatalhöyük males and females demonstrate an inverse relationship where CTI decreases as age and MWI increase. Analyses indicate statistically significant age-related change in MWI amongst the oldest females. Despite age-related loss of bone, no typical fragility fractures are observed. We discuss the role of ageing and lifestyle factors at Çatalhöyük that may have been beneficial to skeletal health and a reduction in the risk of fragility fracture.     

Cortical bone dynamics and age‐related osteopenia in a Longobard archaeological sample from three graveyards of the Veneto region (northeast Italy)

Since the contribution of Brothwell and co‐workers in early 1968, few studies have considered the cortical bone involution in European skeletal series of archaeological interest. The present study concerns the involutive process mechanisms and intra‐ and inter‐sexual variability in femurs of 66 adults belonging to three graveyards of the Longobard era excavated in the Vicenza province (northeast Italy). Cortical thickness and cortical and medullary areas were measured and a correlation matrix was generated for each sex and age class. Intra‐ and inter‐sexual variability were evaluated by two‐tailed t‐tests and a sexual dimorphism index. The results indicate a considerable difference between the sexes, with females showing an earlier and more marked cortical bone loss, as expected. Moreover, comparing the data with the scarce literature available, some discrepancies in cortical bone involution were found in populations with different patterns of adaptation, suggesting the need for further studies in this direction aimed at understanding bone environment dynamics.

Metacarpal radiogrammetry: a useful indicator of bone loss throughout the skeleton?

Metacarpal radiogrammetry has received increasing interest in recent studies of archaeological human bone in facilitating the identification of age-related cortical bone loss and osteoporosis risk in the past. The technique is relatively simple and non-destructive, and existing comparative clinical data is an advantage in its application to archaeological samples. In order for metacarpal radiogrammetry to be useful in identifying individuals that could have been at risk of fracture in the past, cortical bone loss as measured at the second metacarpal is assumed to be reflective of bone loss occurring throughout the skeleton and across the metabolically different cortical and trabecular bone. Archaeological studies have frequently relied on literature reviews of clinical data to justify the technique as valid and useful. However, the present study has examined whether cortical bone loss measured in the second metacarpal is similar to bone loss measured at specific skeletal sites that are more frequently affected by osteoporosis-related fracture. Skeletons from two post-medieval collections from London, UK, Redcross Way and Farringdon Street (lower burial ground of St. Bride's Church) were studied. The results of the present study demonstrate that the second metacarpal is useful in identifying age-related bone loss at sites that are predilected to osteoporotic fracture, most notably the distal radius, which is prone to Colles' fractures. Metacarpal radiogrammetry also correlates well with bone loss in skeletal sites that are primarily composed of trabecular bone, including the fourth lumbar vertebra (a site of compression fractures) and the iliac crest (the location for clinical biopsies). The present study also confirms previous findings of significant differences between the pattern of cortical bone loss between the metacarpal and the femur. The poor relationship between these two areas is most likely attributable to mechanical loading.

ON THE COMPILATION OF A BIBLIOGRAPHICAL DIRECTORY OF “SOVIET GEOGRAPHERS”

A new directory of Soviet geographers is to be published later this year by the Geographical Society of the USSR. It includes 1,947 geographers active in the period 1917-January 1, 1990. This group of geographers is analyzed by specializations in geography and by cities in which they work (translated by Chauncy D. Harris).     

Folder 5, box 92

This short paper is concerned with a map of central Japan that the later University of Chicago Professor of Geography, Chauncy Harris, drew in September 1944, when he was assigned as an US Army Private to work at the headquarters of the Research and Analysis Branch, Office of Strategic Services. The map provided a functional classification of Central Japanese cities, highlighting those that specialized in manufacturing. It was precisely these set of cities that were targeted for firebombing by the US Airforce from March 1945.     

CAN SEARCH‐MATCHING MODELS EXPLAIN MIGRATION AND WAGE AND UNEMPLOYMENT GAPS IN DEVELOPING ECONOMIES? A CALIBRATION APPROACH*

ABSTRACT A recent theoretical literature tries to understand the migration pattern in developing economies through the lens of search‐matching (SM) models, but there has been little empirical support for these models. This paper tries to fill this gap by examining whether the models are consistent with the data from developing economies. Combined with some suggestive statistics, our calibration exercise reveals that when augmented with additional frictions (fixed costs of starting up new businesses and mobility costs), our SM model can account for the data and is at least more consistent with the data than traditional Harris–Todaro models.     

Tropical nightglow observations and predictions from ionospheric models

To study the tropical nightglow emissions in the vicinity of the Brazilian magnetic anomaly, two balloons were flown in February 1973 and 1977 carrying photometers. The behaviour in the tropical nightglow of the 630 and 557.7 nm lines is described and compared with predictions based on recent ionospheric models. Possible effects of the magnetic activity on the F2-layer in the tropics are suggested which are not accounted for by the ionospheric models.

Lingual cortical mandibular defects (Stafne's defect): an anthropological approach based on prehistoric skeletons from the Canary Islands

While posterior lingual mandibular depressions (Stafne's defect) are often discussed in clinical reports, they are rarely the subject of anthropological research. This situation is paradoxical since osteologists and skeletal biologists are in a position to enhance understanding of the trait's aetiology by systematically recording the trait in recent and prehistoric skeletal collections. This report reviews anthropological studies of cortical defects of the mandible, recommends a protocol for recording observations in trait variation, and presents new data for the prevalence of Stafne's defect—lingual cortical defects of the mandibular corpus. Among the Guanches of Tenerife in the Canary Islands (Spain), the prevalence of lingual cortical defects is 3.32% (15/452), males are more frequently affected than females, and there is a tendency for individuals with antemortem tooth loss to display larger lesions than individuals without antemortem loss of teeth. Defects of the left side are somewhat more variable in position than defects located on the right. In comparative perspective, prevalence of lingual cortical defects among the Guanches is high, given the overall 1.07% prevalence reported for archaeological series (Finnegan & Marcsik,1980), but is similar to figures reported for the Avar period sample from Hungary 3.73%. Prospects for the use of lingual cortical defects as non‐metric traits of value in population distance studies remain uncertain since variation in trait expression may have a high environmental component. However, if human osteologists routinely include observations of lingual mandibular cortical defects in their analysis of skeletal collections, the data required to elucidate factors responsible for the trait's cultural, ecological, temporal and geographical patterning will more rapidly become established.

Effects of a nineteenth century below-knee amputation and prosthesis on femoral morphology

Access to the lower limbs from a historically-identified nineteenth century below-knee amputee who had worn a hardwood ectoprosthesis for an extended time prior to death provides a natural experiment for investigating the morphological and histological effects of the resulting altered mechanical environment. Osteometry (measuring total bone size), cross-sectional geometry (bending and axial rigidity) and histology (bone turnover rate) are assessed. A reduction in size and geometric strength, along with an increase in cortical bone turnover, indicate that the midshaft and distal regions from the affected femur were partially shielded from functional strain. Structural compliance of the prosthesis, probably originating from design and material of manufacture, to some degree preserved the mechanical and morphological integrity of the proximal subtrochanteric region. The results of this case study are consistent with contemporary theory in skeletal biomechanics, for example, Frost's Mechanostat, which suggests that insufficient functional strain promotes intracortical remodelling and endosteal expansion.     

A case study of possible differential diagnoses of a medieval skeleton from Denmark: leprosy,ergotism, treponematosis,sarcoidosis or smallpox?

This paper uses macroscopic and radiological examinations to provide differential diagnoses of pathological lesions in the skeleton of a young woman, 20–25 years of age, which triggered the Danish palaeopathologist Vilhelm Møller‐Christensen's interest in leprosy. The skeleton was incomplete, but the majority of bones of the upper body, as well as the skull, were present. The pathological changes consisted of medullary and cortical lytic foci, periosteal reaction and enhanced cortical density. The lesions were most extensive on the left side, especially around the elbow, wrist and scapula. Treponematosis, leprosy, smallpox, ergotism, rheumatoid arthritis, tuberculosis and sarcoidosis are all reviewed with regard to bone and joint pathology and their likelihood of being the correct diagnosis. We concluded that the most plausible diagnosis is treponematosis, but neither sarcoidosis nor smallpox can be completely excluded. Copyright © 2007 John Wiley & Sons, Ltd.
