Activity Reconstruction of Post‐Medieval Dutch Rural Villagers from Upper Limb Osteoarthritis and Entheseal Changes

The first objective of this study is to reconstruct levels and types of physical activity and associated sexual and social differences using human skeletal remains from the predominately 19th century Dutch cemetery of Middenbeemster. For most individuals, life in the Beemster centred around dairy farming and was heavily based on manual labor, with a purported higher class of wealthier individuals performing less manual labor. Two skeletal markers of activity are examined in the upper limb of late young adult and middle‐aged adults of both sexes (26–49 years, n = 69): osteoarthritis (OA) and entheseal changes (EC). Results support the hypothesis that the majority of the population engaged in high levels of physical activity; however, a group with a clearly lower or different pattern of activity, possibly representing a higher, less active class, was not discernible. This may be due to a low number of less active individuals in the analysed sample and/or the heterogeneity of occupations and activities. A gendered division of labour was evident in the EC data with males having more pronounced muscle attachments in almost all sites, especially the biceps brachii, used primarily in lifting. Females had more pronounced triceps brachii, which may be due to activities that required pushing or pulling with the elbow in a flexed position. The prevalence and severity of OA did not differ between the sexes. While this could be interpreted to indicate men and women engaged in a similar level of strenuous activity, hormonal and anatomical differences limit the strength of the comparison. The second objective of this study is to evaluate the concordance of OA and EC as activity markers. The correlation between OA and EC is very low, illustrating their variable and complex etiologies. Etiological factors need further research for OA and EC to become more reliable activity markers. Copyright © 2014 John Wiley & Sons, Ltd.     

Modern human,early modern human and Neanderthal limb proportions

The limb proportions of 686 subjects (461 men and 225 women) from five ethnic groups (White, Inuit, Gurkha, Bantu, San) have been compared. Stature, limb and skeletal measurements were taken directly from the subjects by one observer. The brachial and crural indices of the Whites were markedly smaller (lower) than those of the other populations. The crural indices of the Inuit were similar to those of the two African populations, but this may be an artefact from relatively small numbers for the Inuit population. There is no sexual dimorphism for the brachial index, but men have larger (higher) crural indices than women, a finding which probably relates to the relatively broad pelvises and consequently long femurs of women. The two African populations have long limb lengths standardized for height compared to the Gurkha and Inuit populations, with the Whites intermediate. This finding is consistent with Bergmann's thermoregulatory rule. The correlations between distal abbreviation and limb abbreviation for both the upper and lower limbs are poor and negative. Relatively long limbs tend to have smaller distal segments than relatively short limbs and for the legs this may constitute a safeguard for the integrity of the medial and cruciate ligaments of the knee. For these five modern populations distal abbreviation cannot be used as a proxy for limb abbreviation and there is no justification for linking distal abbreviation with climatic selection. Skeletal data relating to nine Neanderthal and 25 early modern humans have also been analysed. The analysis confirms marked limb and distal abbreviation for the Neanderthals compared to early and contemporary modern humans, but this conclusion presupposes that the taxonomic classes are correct and that limb proportions were not used originally as a class discriminant. For these archaic populations there is a moderate positive correlation between lower limb abbreviation and distal abbreviation, but the numbers are small and the confidence intervals very wide. In view of the findings for modern populations, and until more relevant fossils are available, it is probably unwise to use the crural index as a proxy for limb abbreviation in archaic populations.

The Effect of Terrain on Entheseal Changes in the Lower Limbs

One of the main factors involved in entheseal changes (EC) aetiology may be related to the physiological limits of biomechanical loading fixed during bone development, such that higher load during childhood and the adolescent growth spurt leads to a lower frequency of EC during adulthood. In this sense, it is possible that ECs may be related to overloading beyond an individual's normal physiological limits as established during childhood and adolescence. This meta‐analysis tested this aetiological possibility by studying the influence of terrain on the entheses of the lower extremities. The hypothesis is that individuals who inhabited rugged terrain have lower EC than those living in flat terrain. This is because biomechanical loads associated with rugged terrain will lead to a higher normal capacity (defined during skeletal development) mitigating the probability of overloading compared to those living in flat terrain who will therefore have a higher frequency of ECs. To test this, papers reporting EC frequencies in the lower limbs were analysed alongside the local terrain. Terrain was defined into two categories: flat or rugged based on altimetry profile, i.e. the average elevation gains and losses along four specific paths (North‐South, East‐West, Northwest‐Southeast, Southwest‐Northeast). Odds ratios were calculated to compare rugged and flat terrain. The overall results are consistent with the hypothesis that overloading is a factor in EC aetiology. However, when the analysis is conducted by sex and side, this general trend does not always occur. Limitations such as the lack of standardized age ranges could be affecting the outcome, i.e. older individuals have a higher frequency of ECs. The findings of this analysis suggest that the theoretical assumptions associated with the cause of ECs require further testing and evaluation. Copyright © 2017 John Wiley & Sons, Ltd.     

Biomechanical insights into activity and long distance trade in the south-central Andes (AD 500–1450)

Long distance trade has been attributed important social and economic roles in the pre-colonial south-central Andes, but how these trade networks were operated and organised, and the roles played by different populations and social groups (e.g. elites), remain uncertain. This study aims to offer new perspective on these questions through biomechanical analyses of human skeletal remains from a probable key site in these networks, San Pedro de Atacama (SPdA). Groups that were more intensively involved in long distance trade are expected to have been more habitually mobile, and thus to show greater robusticity and less circular lower limb bone cross-sections. Lower limb biomechanical properties of elite and non-elite Middle Horizon groups (MH, AD 500–1000) were compared with subsequent transitional MH-Late Intermediate Period (LIP, AD 1000–1450) and LIP groups from SPdA, and with LIP groups from Pica-8 and the Azapa Valley. The results indicate that MH populations from SPdA had less robust lower limbs and were by inference less mobile than their successors, with no differences between elite and non-elite, while robusticity was elevated in the MH-LIP transition group. Alternative explanations for the results, such as changes in herding activities, cannot be entirely discounted based on current evidence, but the results are consistent with hypotheses that SPdA may have served as a hub on long distance trade networks during the MH, before residents became more actively involved in long distance trade following the collapse of key links with the Tiwanaku polity. The results also indicate similar levels of robusticity among LIP populations at SPdA, Pica-8 and in the Azapa Valley, implying they may have been involved in trading activities to a similar extent, and perhaps to a greater extent than SPdA MH groups, as regional intergroup relationships changed.     

Draught cattle and the South Scandinavian economies of the 4th millennium BC

Abstract

This paper presents an osteomorphological survey of evidence for draught utilisation of cattle in the South Scandinavian TRB culture. The investigations focus on morphological changes in the lower limb bones of domestic cattle from a large number of archaeological sites and from several individual cattle skeletons found in bogs. The osteological results are discussed in the context of other lines of evidence, both archaeological and environmental, and one of the main themes of this discussion is the relationship between the adoption of animal traction and developments in land use. Furthermore, developments in the economic complex of the South Scandinavian TRB culture are compared with certain trends further south in Europe.     

Disentangling long bones of foxes (Vulpes vulpes and Alopex lagopus) from arctic archaeological sites

To discern the presence of two anatomically close species within an archaeological assemblage is always a problem for the analyst. A particularly interesting case is the distinction between the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus), which is often determined using non-rigorous criteria and producing results that must be regarded with caution. Classical methods for separating these two species and determining sexual dimorphism, and eventually the sex ratio, such as analyses using uni- and bivariate plots, are based on arbitrarily fixed limits between sexes. In this text, a more robust statistical method termed mixture analysis (MA) is used to determine the species of limb bones from foxes. First, the MA is applied to a sample of each species using metric data taken from a collection of present-day fox skeletons. Afterwards, the MA is applied to archaeological samples dated to the Dorset period and retrieved from the Tayara site (near Salluit, South Hudson Strait, Nunavik). The results clearly demonstrate that the greatest length (GL) of long bones, especially the humerus and tibia, is the best measurement for distinguishing the species, followed by the distal breadth and the proximal breadth; and that GL is better suited for sexing foxes. The results of MA applied to the Tayara site collection lead to the conclusion that the red fox is present along with the arctic fox among the assemblage, and that there is no fox body size change during the last two millennia in the Eastern Arctic.     

Modeling the Cyclic Flexural and Shear Response of the R. C. Hollow Box Columns of an Existing Viaduct

The cyclic response of R.C. hollow box columns, constructed as part of a typical single-column bent viaduct, built in the 1970’s in Central Europe, was studied both experimentally and analytically. Moderate displacement ductility capacity (between 3 and 4) was observed regardless of the column construction details, which are nowadays considered inappropriate for seismic regions. Standard analytical flexural models correlated with the experimental results quite well. Shear strength was estimated using the two methods included in the EC8 standards, as well as the method developed at the University of California, San Diego. Quite different results were obtained. The most accurate was the third method.     

Distinguishing between archaeological sheep and goat bones using a single collagen peptide

We describe a method of isolating and analyzing a single collagen peptide able to distinguish between sheep and goat bone collagen. The 33 amino acid peptide from both sheep and goat collagen was sequenced and shown to differ between the two species at two positions. Analysis of a range of caprines indicated that the sequence changes occurred between the divergence of the Himalayan tahr (Hemitragus jemlahicus) and the ibex (Capra ibex) and that the proposed goat marker is diagnostic of all Capra species and breeds. The survival of these markers in archaeological bones was tested using a set of 26 ovicaprid specimens from Domuztepe, a Neolithic site in south central Turkey. These markers were used to test the osteological determination of 24 of the Domuztepe bones, and determine the species for two immature specimens. The collagen-peptide method has advantages over other non-morphological methods of sheep/goat distinction because of the long-term survival of collagen over other biomolecules such as ancient DNA. The results also highlighted the problems in relying upon one morphological criterion, in this case on the distal radius, to distinguish between sheep and goat bones.     

Body Mass Estimates in Dogs and North American Gray Wolves Using Limb Element Dimensions

Body mass is a key biometric that is useful in interpreting many aspects of an animal's life history. For many species, including dogs and wolves, methods for estimating body mass are not well developed. This paper assesses the utility of using limb dimensions to predict body mass in dogs and North American wolves. Regression analyses are utilized here to explore the correlations between limb dimensions and body masses of modern dogs and wolves, all of known body mass at death. These analyses reveal that a number of limb end dimensions are correlated with body mass in both dogs and wolves. Regression formulae generated through the analyses appear to allow body masses to be predicted with relatively small margins of error, often less than 10%. Formulae are calculated for groups with and without juveniles. In some cases, the dimensions of the juvenile specimens plot distinctly from those of adults, indicating that regression formulae specifically for juvenile canids may be needed. The strength of the limb dimension correlations is then compared with that of regression formulae for dog and wolf cranio‐mandibular dimensions. For the dogs, the cranio‐mandibular dimensions appear to slightly out‐perform the limb element dimensions in predicting body mass. The wolf limb dimensions, however, always appear to provide better predictions of body mass than do the skull dimensions. The newly developed regression formulae are applied to several Middle Holocene dog skeletons from Siberia for which previous body mass estimates are available, the latter based on cranial dimensions. These two sets of estimates are then compared. The overall results of our study indicate the need for further research, particularly with larger sample sizes, including more juvenile specimens. We also argue that work on body size estimation in single dog breeds may be warranted in some cases. Copyright © 2016 John Wiley & Sons, Ltd.     

A Tale of Two Cities: A Decomposition of Recent Fertility Changes in Shanghai and Hong Kong

In the past 20 years, Hong Kong and Shanghai's total fertility rates (TFR) have undergone drastic changes: first declining and then rebounding. We use a decomposition method to assess changes in the TFRs of these two cities during the period 1990–2010. During the period of decline from 1990 to 2000, the decrease in marital fertility rate (MFR) was the major cause behind Shanghai's TFR decline; the decrease in nuptiality and MFR were equally responsible for the decline in Hong Kong's TFR. During the 2000–2010 period, although the decline in nuptiality exerted downward pressure on TFR, both cities experienced an increase in TFR mainly due to an increase in the MFR. Analysis of the difference in TFR between the two cities in 2010/2011, also reveals that Hong Kong's marriage delay has a negative impact on fertility and it is the higher MFR that leads to a higher TFR than Shanghai's TFR. It also shows that a reduction of first- and second-order births is equally responsible for Shanghai's lower MFR. Despite the one-child policy in Shanghai, some couples continue to postpone their first births, while others have even chosen to be childfree (a preferred term to ‘childless’). The tempo distortion is diminishing more prominently in Hong Kong, while the decline in fertility aspiration adds much uncertainty to future fertility trends in Shanghai.

Thorn Lesions in a Modern Osteological Collection of Guanaco (Lama guanicoe): A New Paleoenviromental Proxy and Its Implications for Archaeofaunal Assemblages

This paper provides a detailed analysis of thorn lesions found in lower limb elements of a modern osteological collection of guanaco (Lama guanicoe). Four types of lesions were recorded: (1) thorns visible on the bone surface, (2) bony reaction with relief, (3) small negative scars and (4) medium negative scars. The methods used to recognise, record and quantify these lesions are presented. As a result, 35 of the 36 individuals analyzed contained one or more types of lesions. The highest concentrations of lesions were recorded on the anterior view of the metacarpal shafts. All the age ranges were affected by lesions; however, individuals between the ages of 1 and 3 years were the most affected, whereas those between the ages of 0 and 1 year contained the least amount of lesions. To provide examples of how thorn lesions can be identified and used as a paleoenvironmental proxy in the fossil record, we analyzed two archaeological sites from different phytogeographic provinces: Bajo de la Quinta (Monte phytogeographic province) and Calera (Pampa phytogeographic province). Results found that 25% of the elements from the Bajo de la Quinta site contained lesions, whereas none of the elements from the Calera site showed evidence of lesions. When detectable in the fossil record, thorn lesions can provide an indirect approximation of the paleoenvironment. Copyright © 2011 John Wiley & Sons, Ltd.     

Between cooperation and competitive bargaining: the Council of Europe,local and regional networking,and the shaping of the European Community’s regional policies, 1970s–90s

Abstract:

In many ways, the Council of Europe paved the way for European Community (EC) action in local and regional affairs. It was the first European organisation to establish a conference of local and regional authorities in 1957, in which local actors and associations were represented and tried to influence the shaping of European regional policies. This article analyses the links between the Council of Europe and the EC in the development of regional policies from the 1970s to the 1990s by focusing on three transmission vectors: through institutional cooperation between the two European organisations; through competitive bargaining among local and regional groups; and through intensive lobbying at EC level. It argues that the transfer of ideas was not so much achieved through cooperation between the organisations’ experts or political committees but rather by means of transregional networking promoting the idea that local and regional authorities had to be associated with the elaboration and implementation of European regional policy. From 1988, these networks shifted their attention away from the Council of Europe towards the EC because of the possibility to receive direct funding from the European Commission.     

Sexual dimorphism in diaphyseal cross‐sectional shape in the medieval Muslim population of Écija,Spain, and Anglo‐Saxon Great Chesterford,UK

Differences in adult male and female activity patterns may influence levels of sexual dimorphism in physical dimensions, including the cross‐sectional shape of long bone diaphyses. Previous studies of archaeological populations have demonstrated significant differences in diaphyseal shape between males and females. In this study, dimorphism in external diaphyseal shape of upper and lower limb bones (reflected in indices of external diaphyseal diameters), and bilateral asymmetry in these indices, were examined in two medieval populations: Muslim Écija (Spain) and Anglo‐Saxon Great Chesterford (UK). Attempts were made to relate observed patterns to documentary and other osteological evidence for differences in male and female activity patterns. While few significant differences in upper limb bone cross‐sectional shape were observed in either population, significant differences in shape were found in the lower limb diaphyses at Écija at the femoral midshaft and tibial foramen and midshaft levels, and at the tibial midshaft for Great Chesterford. Comparison with published data suggests that these differences are marked for Écija, and perhaps fairly high for Great Chesterford compared with other populations with an agriculture‐based economy. This is consistent with documentary and osteological evidence suggesting marked gender differences in behaviour in medieval Muslim Spain. No significant differences in bilateral asymmetry were found, but the effects of small sample size cannot be ruled out. Copyright © 2008 John Wiley & Sons, Ltd.     

Diagnostic criteria for developmental dislocation of the hip in human skeletal remains

Dislocation is the most severe form of developmental dysplasia of the hip (DDH). It significantly impairs hip function in the young, and may lead to debilitating early‐onset osteoarthritis in adults. To our knowledge no thorough study of a large skeletal population has ever been undertaken to determine the wide range of diagnostic criteria for this condition in pathological specimens. To identify these criteria we have analysed the cases of developmental dislocation from a large series of 6000 individuals (6580 hips) from the medieval cemetery at Spitalfields in London, UK. We describe the changes at the true acetabulum, and have created a four‐stage classification of the false acetabulum. The skeletal response to the altered biomechanics and limb shortening that occurs in developmental dislocation is described in the pelvis, lower limb and spine. This includes asymmetric growth in childhood, and asymmetric degenerative change in adulthood. We conclude with a discussion of the clinical literature on developmental dislocation of the hip that will aid palaeopathologists to estimate the symptoms that an excavated individual may have experienced during their lifetime.

RESEARCH NOTES AND APPLICATION REPORTS U-SERIES DATING OF THE DEPOSITS FROM THE PRINCE CAVE,NORTHERN ITALY

The travertine layers of the Prince Cave have been dated by the U-series methods. The age of the lower part of the breccia Br2, where a human iliac fossil bone was discovered, is between 110 and 160 ka. and the upper part of Br2, together with the breccia Br1, between 79 and 160 ka. The reliability of the results is confirmed not only by the consistency of the dates obtained from samples in close proximity, but also by the agreement between two independent dating methods: Th-230/U-234 and Th-227/Th-230.     

Bone remodelling following a lower leg fracture in the 11,000‐year‐old hunter‐gatherer from Vado all' Arancio (Italy)

The Upper Palaeolithic skeleton from Vado all'Arancio (Italy), dated to about 11,330 BP, exhibits a severe ankle fracture healed with residual deformation. Following recovery, this young hunter‐gatherer continued to walk for an extended period of time, albeit in a mechanically altered manner. While right‐left differences in external lower limb bone measurements are relatively low, biomechanical analysis of femur and tibia indicates unusually pronounced asymmetry in all cross‐sectional measures of diaphyseal strength. Asymmetry results primarily from normal side endosteal hypertrophy, and not from hypotrophy of the injured limb, suggesting that this individual resumed active life following recovery. This pattern of asymmetry underscores the role of physical activity in maintaining bone mass. Copyright © 2002 John Wiley & Sons, Ltd.     

SITE EFFECTS BY H/V RATIO: COMPARISON OF TWO DIFFERENT PROCEDURES

In this article, H/V ratio are evaluated using different spectral techiniques applied to both earthquake and microtremor data (Nakamura technique). In particular, in order to avoid numerical instability, two different numerical techiniques are taken into account: (a) a smoothing procedure applied to the spectra of the seismogram components and (b) a regularization method applied to the H/V ratio (Landweber scheme). The data set consists of more than 70 earthquake events recorded by three component sensors displaced in the town of Fabriano (Central Italy) during the Umbria-Marche sequence started on September 1997. The local magnitudes range between 2.7 and 4.4, while the epicentral distances range between nearly 30 and 60 km. The stations were set to continuous recording so that a huge amount of microtremors was stored. The results are compared in terms of predominant frequencies and amplification levels in order to point out the influence of the adopted methods. The H/V ratio provides similar results if applied to a smoothed version of both earthquake and microtremor spectra, confirming that Nakamura technique is a cheap and a fast method to collect information on the site amplification effects. Moreover, the results relevant to earthquake data seem not to depend on the method used to stabilize the H/V ratio, whereas those relevant to microtremor data does. The explanation of this fact is suggested by the behaviour of the Landweber filter showing that the predominant frequency detected by means of microtremor data lies in a high instability region of the spectra.

Topic Modeling and Text Analysis for Qualitative Policy Research

This paper contributes to a critical methodological discussion that has direct ramifications for policy studies: how computational methods can be concretely incorporated into existing processes of textual analysis and interpretation without compromising scientific integrity. We focus on the computational method of topic modeling and investigate how it interacts with two larger families of qualitative methods: content and classification methods characterized by interest in words as communication units and discourse and representation methods characterized by interest in the meaning of communicative acts. Based on analysis of recent academic publications that have used topic modeling for textual analysis, our findings show that different mixed‐method research designs are appropriate when combining topic modeling with the two groups of methods. Our main concluding argument is that topic modeling enables scholars to apply policy theories and concepts to much larger sets of data. That said, the use of computational methods requires genuine understanding of these techniques to obtain substantially meaningful results. We encourage policy scholars to reflect carefully on methodological issues, and offer a simple heuristic to help identify and address critical points when designing a study using topic modeling.
