An investigation of the frequency of squatting facets in Later Stone Age foragers from South Africa

Distinctive morphological changes attributed to a habitual squatting posture were observed on the distal femur, distal tibia and on the talar neck of Later Stone Age (LSA) foragers. The frequency of squatting in LSA foragers (n = 56) was determined by the presence of anatomical features of joint hyperflexion. Three South African comparative skeletal groups from different time periods were also analysed: skeletal remains of early farming populations (n = 17), 18th century ‘Free Blacks’ and/or slaves from Cobern Street, Cape Town (n = 21), and a modern cadaver sample (n = 29). The results show that 28 out of 56 LSA foragers (50%) were habitual squatters; 13 out of 17 farmers (76.5%) and one of 21 individuals from the Cobern Street collection (4.8%) demonstrated squatting facets. No anatomical squatters were found in the modern cadaver sample. There was no significant sex difference between squatters and non‐squatters. Hence at least half of the LSA foragers and farmers were habitual squatters, according to the signs of joint hyperflexion. Squatting is a comfortable position for those used to it because the body weight is supported with minimal muscular activity. Two probable reasons are suggested for the difference in postures adopted by the different groups: (1) availability or lack of availability of furniture and (2) cultural and individual differences in resting posture.

Experimental study of polycrystal growth from an advecting supersaturated fluid in a model fracture

We present real‐time observations of polycrystal growth experiments in transmitted light in an accurately controlled flow system with the analogue material alum [KAl(SO₄)₂·12H₂O]. The aim of the experiments is to obtain a better insight into the evolution of vein microstructures. A first series of experiments shows the evolution of a polycrystal at supersaturations between 0.095 and 0.263. The average growth rate of the crystals is influenced by growth competition and the depletion of the solute along fracture length. Growth competition is controlled by crystallographic orientation, crystal size and crystal location. In addition, the growth rate of an individual crystal facet also shows variations depending on the facet index, facet size and flow velocity. These variations can influence the morphology of the grain boundaries and the microstructures. The aim of the second series of experiments is to investigate the growth evolution of rough/dissolved facets in detail. The growth distance required for the development of facets is around 15 μm. In all the experiments, we observe that the measured growth rates have a much larger range than predicted by alum single‐crystal growth kinetics. This is due to the combined effect of the facet index and the crystal size. Furthermore, at high supersaturations, the facet growth rate measurements do not fit the same growth rate equation as for the experiments at lower supersaturations (<0.176). This can be explained by a change in the growth mechanism at high supersaturations with more influence of volume diffusion, relative to advection of the bulk solution on the growth rate. This effect can also cause a more homogeneous sealing pattern over fracture length. At high supersaturations, the larger crystals in these experiments incorporate regularly spaced fluid inclusion bands and we propose that these can be used as an indicator for high palaeo‐supersaturation. The final microstructures of the experiments show no asymmetry with respect to the flow direction.     

A case of valgus ankle in an early Pleistocene hominin

Bipedal locomotion is a defining character of the hominin lineage. A skeletal correlate of bipedality is a perpendicularly oriented tibia relative to the plane of the ankle joint, positioning the foot directly under the centre of mass. Non‐human primates, in contrast, possess a tibial shaft that tilts laterally away from the plane of the ankle joint (valgus ankle), which positions the foot in inversion and is adaptive for arboreal climbing. KNM‐ER 2596 is a small distal tibia from 1.9 mya sediments at Koobi Fora, Kenya. Though it possesses some morphologies functionally linked to bipedality, such as an expanded metaphysis, it also possesses a valgus tilt to the ankle. We test the competing hypotheses that the KNM‐ER 2596 tibia is from a cercopithecoid, a non‐human hominoid, or a pathological hominin. A survey of the orthopaedic literature and a comparative study of modern human and non‐human primate tibiae support the hypothesis that KNM‐ER 2596 is from a hominin. In order to investigate the non‐phylogenetic causes of valgus ankle, we examined human skeletal tibiae with valgus tilt secondary to fracture of the distal fibula. Untreated breaks of the lower third portion of the fibula during childhood can result in a valgus tilt to the distal tibia and occasionally other peculiar morphologies found in the KNM‐ER 2596 tibia such as a superoinferiorly atrophied medial malleolus. The morphology of this tibia is incompatible with hypotheses that it is from a cercopithecoid or a hominoid, and instead, we suggest that KNM‐ER 2596 belonged to a hominin that may have suffered a fracture of the lower left fibula as a juvenile.

SQUATTING ON GOVERNMENT LAND

This paper presents an economic theory of squatter settlements in developing countries. It adds to the existing literature by explicitly modeling squatting on government‐owned land and presents a unified framework for analysis of issues related to squatting, urban planning and policy. In the model, a squatter‐organizer optimally controls squatting so as to forestall eviction. The model highlights how the existence of an eviction cost leads to formal residents tolerating squatting, trading‐off “open space” to avoid paying taxes toward evicting squatters. The paper derives comparative‐static results under some functional form assumptions. The analysis is extended to examine the comparative‐static effects for the case where squatters freely migrate into the city. The framework for exploring a combined model of squatting on government and private land is also laid out. Finally, some policy analysis of squatter formalization is carried out.     

Correlation between dental occlusal wear and approximal facet length

The aim of this paper is to examine the relationship between occlusal surface wear and approximal facet length in a North American archaeological sample of modern human hunter–gatherers (n = 111) and agriculturalists (n = 123). First maxillary molars (M¹) were selected. The approximal wear facet was measured on the mesial surface of each M¹ at the widest breadth using needle tipped digital callipers. Digital images were taken of the occlusal surface and wear was recorded as the percentage of dentine exposed to the total occlusal surface. Independent age estimate was based on age‐related changes, (pubic symphysis and auricular surface). Results show the hunter–gatherers had a significantly faster rate of wear on both tooth surfaces compared to the agriculturalists in each of the four age groups. Both lifeway groups showed a positive correlation between the two tooth surfaces during the early stages of tooth wear (less than 25% occlusal wear), where the percentage of occlusal wear and the length of the approximal facet increased at a similar rate. During the middle and final stages of tooth wear (occlusal wear greater than 35%) there was a strong negative correlation between the two surfaces in both groups. It is suggested this pattern is due to the shape and function of the M¹. Both correlations were more extreme in the hunter–gatherers than the agriculturalists. When the per cent of occlusal wear exceeded 35% the length of the approximal facet started to decrease, and it is therefore recommended studies that include approximal wear exclude molars with heavy occlusal wear.

Squatting among the neandertals: A problem in the behavioral interpretation of skeletal morphology

The analysis of the Neandertal and Skhul hominid metric and non-metric lower limb variations which have been considered indicative of squatting suggests that squatting was a common position of repose among these Pleistocene hominids. Although the total morphological pattern of the Neandertals supports this conclusion, few of the variations commonly associated with squatting provide conclusive evidence of previous habitual squatting. It is necessary to consider each variation with reference to its etiology and its association in the total morphological pattern before deriving similar behavioral interpretations from the skeletal morphology.     

Queering Communia: the politics of positionality when doing research on squatting in Rome

The politics of positionality in relation to sexuality and desire has remained unquestioned when investigating autonomous and alternative spaces, these studies mainly focused on political positionality through the adoption of militant and action-based methodologies. The article tries to fill this void by discussing issues of positionality related to sexuality and desire when doing research on squatting. The main aim is to discuss how entering the field in social movements research through an action-based approach can lead the researcher to involve every aspect of their life, including sexuality and desire. By discussing the case of my PhD research project focused on the re-emergence of squatting initiatives in Rome, the article is aimed at showing how my sexuality, notably my previous engagement in queer politics, has represented an important issue when negotiating with my research partners. When discussing the strategies and activities I adopted, the article plays with the tensions between being queered by the fieldwork and queering it, showing the possibilities of contamination as well as the limits of the politics of positionality.     

The Squatters' Movement in Europe: A Durable Struggle for Social Autonomy in Urban Politics

Squatting empty properties for living or to develop public activities has lasted in European cities for more than three decades. Although local and national contexts differ significantly, there are also some general trends and patterns that deserve careful attention. When squatting occasionally appears in public debates, controversy is generated and many gaps open between academic, social and political perceptions. In this article I use evidence from several European cities to argue that the squatters' movement has produced an original impact in urban politics. The main feature of this impact has been to generate a relatively wide autonomous and mainly non‐institutional mode of citizen participation, protest and self‐management. How has this been possible? Which are the specific contributions made by this urban movement? These are questions that both scholars and activists continuously claim to be relevant, so that this research attempts to offer some general answers based on detailed comparisons and experiences.     

The chronology of epiphyseal union in the hand and foot from dry bone observations

Dry bone data for epiphyseal union at the hand and foot are scarce, incomplete or inexistent. This study documents the timing of fusion of secondary ossification centres at the hand and foot in a sample of known‐age human skeletons. The sample comprises 92 individuals (49 females and 43 males), between the ages of 9 and 22 years, from the identified skeletal collection curated at the National Museum of Natural History in Lisbon, Portugal. Epiphyseal union was recorded on the right and left side at the long bones of the hand (metacarpus and phalanges) and foot (metatarsus and phalanges), and also at the talus and calcaneus, using a three stage scheme (non‐fused; partially fused and completely fused). In the hand, intra‐observer agreement was 99% and inter‐observer agreement was 98%. In the foot, both intra‐ and inter‐observer agreement reached 100%. Lateral asymmetry was not significant and only 1.1% of the individuals in the sample were found to be asymmetric in the stage of epiphyseal fusion (1.8% in the hand and 0.3% in the foot). A minimum mean advancement of 1–2 years in females relative to males was observed. In the hand bones, epiphyseal union occurred between 12–18 years in females and 16–18 years in males. Comparatively, in the foot bones, epiphyseal union occurred slightly later, with the exception of the talus and calcaneus, which are the earliest bones to mature. Data in this study can be used to estimate the age of unidentified skeletal remains, either directly or by aiding in the modification of incomplete or imprecise data that have been collected over the years.

New cultural geographies of disability: Asian values and the accessibility ideal

The ideal of a 'barrier-free environment' is promoted in developed countries as a means of increasing the independence and mobility of disabled people. The adoption of this concept for developing countries requires critical analysis. Indonesia, for example, has formulated a physical access code, but has not succeeded in the implementation. The focus of this article is on middle-class professional disabled people in cities in Indonesia. Indonesian collectivist values and unequal status that arise from the feudal system do not encourage independence. Such values and the restrictive and inadequate public infrastructures render disabled people invisible in public. The availability of maidservants and chauffeurs assists urban disabled people from the middle class. They may be professionals, who desire to be independent in mobility and other daily living activities. Ambulant disabled people are also excluded from social life due to the custom of squatting and sitting on the floor for household work and traditional socializing. As a result of these factors and the current unstable social, economic and political conditions in Indonesia, barrier-free design is not a priority in most planning and design and seems futile in its realization.     

Differential diagnosis of an unusual tibial pathology from Peru

During an osteological analysis of human skeletal remains from the site of Punta Lobos (Huarmey Valley, northern coastal Peru), an unusual erosive lesion of the cortex with periosteal reaction was observed on a right tibia. The authors undertook a review of paleopathological and medical literature to arrive at a differential diagnosis. The lesion is determined to be a non‐malignant growth, possibly a large periosteal ganglion, though a diagnosis of periosteal chondroma (a benign neoplasm) or other uncommon neoplasm could not be definitively ruled out.

The introduction of multiculturalism in Canada and Australia, 1960s–1970s

This article compares the emergence of a policy of multiculturalism in Canada and Australia between the 1960s and 1970s. It charts the rise of the policy in the two countries through the adoption of a philosophy of multiculturalism as the basis of their national identities. There is a distinction between philosophy and policy: a multicultural policy emerged out of a philosophy of multiculturalism. Furthermore, a philosophy of multiculturalism replaced the ‘new nationalism’ as the foundation of the national identities of both English‐speaking Canada and Australia. The abandonment of the White Canada and White Australia policies and the adoption of non‐discriminatory immigration policies in both countries were also of importance in the emergence of a policy of multiculturalism. There are many similarities in the Canadian and Australian experiences. However, the major differences are explained by the presence of the French‐Canadians in Canada and the early non‐British migration that Canada received in the late‐nineteenth century compared with Australia.     

Skeletal markers of occupational stress in the Fur Trade: A case study from a Hudson's Bay Company Fur Trade post

The Seafort Burial Site (FcPr100) is a Fur Trade Period cemetery located near the town of Rocky Mountain House, Alberta. The results of recent analysis of skeletons recovered during salvage excavations between 1969 and 1971 suggest that three males in this sample were voyageurs in the employ of the Hudson's Bay Company. Vertebral osteophytosis and osteoarthritis, Schmorl's nodes, muscle origin robusticity and new bone formation at entheses and syndesmoses, and osteoarthritis at the elbow and shoulder joints provide evidence for carrying, lifting, and paddling or rowing. The presence of accessory sacral facets also may be stress-related. In addition, the development of accessory articular facets on the metatarsals and proximal pedal phalanges may indicate activity-induced stress from hyperdorsiflexion of the toes in habitual kneeling, such as when river canoeing.     

NON‐DESTRUCTIVE ANALYTIC METHOD USING XRF FOR DETERMINATION OF PROVENANCE OF ARCHAEOLOGICAL OBSIDIANS FROM THE MEDITERRANEAN AREA: A COMPARISON WITH TRADITIONAL XRF METHODS*

A non‐destructive analytical method using wavelength‐dispersive X‐ray fluorescence (WDXRF) that allows the establishment of the provenance of archaeological obsidians was developed and a comparison with the classical XRF method on powders is discussed. Representative obsidian samples of all the geological outcrops of archaeological interest of the Mediterranean area (Lipari, Pantelleria, Sardinia, Palmarola and the Greek islands of Melos and Gyali), were analysed with the normal procedures used in rock analysis by XRF (crushing, powdering and pelletizing). The non‐destructive XRF analysis was instead conducted on splinters taken from the original geological pieces, with the shape deliberately worked to be similar to the refuse usually found at archaeological sites. Since the analysis was conducted on the raw geological fragment, intensity ratios of the suitably selected chemical elements were used, instead of their absolute concentrations, to avoid surface effects due to the irregular shape. The comparison between concentration ratios (obtained by traditional XRF methods) and the intensity ratios of the selected trace elements (obtained from the non‐destructive methodology) show that the different domains of the chemical composition, corresponding to the geological obsidians of the source areas, are perfectly equivalent. In the same way, together with the geological splinters, complete archaeological obsidians, from Neolithic sites, may be analysed and their provenance may be determined. The proposed non‐destructive method uses the XRF method. Due to its sensitivity, low cost and high speed, it is surely an extremely valid instrument for the attribution of the provenance of the archaeological obsidian from Neolithic sites.     

Secularization of immigration policy vs. religion's influence on integration: Israel's non‐Jewish Jews' immigration in a comparative perspective

This article deals with the complex relationship between religion and immigration in Western countries, with an emphasis on Israel. The main argument it presents is that the legal procedures of immigration, i.e. laws relating to the acquisition of civil status, have undergone dramatic secularization, while religion's influence is expressed in the social and cultural aspects of the integration of immigrants belonging to religious minorities. This division reinforces the classical theory of secularization, as the formal boundaries of nations are not subject to religious affiliations, but it also supports the theories of competition and complementation between religion and secularism in the social sphere. The tension in the Israeli case between the immigration, naturalization and integration of non‐Jewish Jews, who are part of the extended Jewish population that is not defined by religious parameters, confirms this thesis. The immigration of hundreds of thousands of non‐Jewish Jews' under the Law of Return based on ethno‐national‐secular parameters is an ultimate expression of the secularization of Jewish nationality. On the other hand, the state's encouragement of non‐Jewish immigrants to convert to Judaism so that they can better assimilate into Jewish society signifies the importance of religion in the social integration aspect.     

French Decorative Ceramics Mass‐Produced During and After the 17th Century: Chemical Analyses of the Glazes

Chemical analyses of a group of Pb silicate–glazed decorative objets d'art showing scenes of the French royal family (Louis XIII and Henri IV), and biblical and classical figures, have been analysed and compared with other similar heritage ceramics and with the rustiques figulines of Bernard Palissy (1510–90) and his followers and imitators. In particular, non‐destructive ion‐beam chemical analyses (PIXE and PIGE) have been performed on 11 ceramic artefacts from the Cleveland Museum of Art (CMA) and a like number from several French museums; results for 13 objects are described in detail in this paper. SEM–EDX has been performed on chips (‘microsamples’) taken from small unobtrusive defective regions on the CMA ceramics. The results of the ion‐beam and SEM–EDX techniques are in good agreement. All the decorative ceramics included uniform non‐opacified glazes. None of these objects can be of 16th century production; all must date from the 17th to the 19th centuries.     

Muhammad Abd al‐Rahman (Phillip) Barker: Bridging Cultural Divides through Fantasy/Science‐Fiction Role‐Playing Games and Fictional Religion

“Muslims” and “Dungeons & Dragons” are rarely discussed in the same sentence. However, one of the earliest fantasy role‐playing games, which left a lasting impact on the industry, was the brainchild of Muhammad Abd al‐Rahman (Phillip) Barker (1929‐2012), a professor of South Asian Studies, an expert in Native American languages, and an American convert to Islam. Like Tolkien, Barker created an enormous fantasy world; however, unlike Tolkien, his world was redolent with Native American and South Asian cultural and religious influences. Through this world, he shared with his fans a nuanced understanding of non‐Western societies, cultures, and beliefs – the facets of the human experience that truly constitute multiculturalism. While fictional religion in role‐playing games has been feared and condemned, fictional religion (and occultism) plays a pivotal role in Barker's work; an exploration of his approach towards fictional religion also sheds more light on the question of why fantasy role‐playing games came across as competitors towards religion. Barker's fantasy world brought people of diverse backgrounds together in a beautiful demonstration of how fantasy and science fiction can bring about intercultural and interreligious tolerance in an otherwise intolerant world. Given the centrality of games such as Dungeons & Dragons to American popular culture, an exploration of Barker's legacy can also be seen in the light of the study of the history and contributions of Muslims in America.     

Buzz Kill: State Adoption of DUI Interlock Laws, 2005–11

Most states have adopted significant measures to reduce the incidence of driving under the influence (DUI) but a DUI death occurs about every 53 minutes; a significant portion of these accidents are the result of recidivist DUI drivers. A relatively new and novel way states can reduce DUI deaths from repeat offenders is to require offenders to install an interlock device on their vehicle, but not all states have adopted this measure. We explore whether the Policy Typology and Policy Diffusion Frameworks can help us understand the politics behind why some states have adopted interlock policies while others have not. Employing over‐time data from the American states our results suggest that the adoption of interlock laws is best explained by internal factors to the state and the adoption of interlock laws by neighboring states. In addition, the adoption of interlock laws is a form of incremental policymaking—states with existing DUI laws are more likely to adopt interlock policies. We conclude that interlock policies diffuse in a manner similar to other regulatory policies and that interlock policies should be categorized as protective regulatory policies rather than social regulatory policies.     

Kinned to be Norwegian: transnational adoptees' positioning in relation to whiteness and the negotiation of nationhood

Embedded in ongoing discussions on everyday nationhood in the context of migration‐related diversity, this article explores how Norwegian transnational adoptees, as border subjects, negotiate their national belonging and identities by positioning themselves in relation to whiteness. By doing so, it further explores the relationship between race and nation. The analysis demonstrates that transnational adoptees position themselves as white when encountering the norm of whiteness, which the author argues in favour of understanding as continued process of doing race. While phenotypic differences trigger a process of racialisation through which transnational adoptees can easily be placed in a minoritised position, adoption provides them with unique access to whiteness, mostly along the negotiable and intertwined dimensions of kinship and the notion of ‘origin’, referred to as the place where they grew up. The article argues that individuals' positioning along majoritisation/minoritisation processes is another important dimension to understand one's multiple and fluid national identity and belonging in migration‐related diversity. The analysis also furthers the discussions on hierarchy of belonging by highlighting the relevance of kinship in intersection with race.
