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.

Of squatting amid capitalism on Yangon's industrial periphery

Across major cities throughout the world, inflated real-estate markets continue to exacerbate crises of affordable housing. Amid such conditions, squatting has emerged as a means to claim urban residence while bypassing the rule of property, resulting in densely populated informal settlements stretched along urban peripheries, most notably in the Global South. But in what respect might squatting be said to have anti-capitalist content? But does the challenge squatting poses to private property mean the practice is unambiguously anti-capitalist? The case presented here illustrates how squatting – initially a challenge to the rule of private property – becomes imbricated with wider relations of extraction and rule and with the broader capitalist context more generally.     

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.     

Total ozone changes in the northern hemisphere mid-latitudinal belt (30–60°N) derived from Dobson spectrophotometer measurements, 1964–1988

A statistical analysis is presented of the daily values of total column ozone obtained during 1964–1988 from a network of 24 Dobson instrument stations located within the mid-latitudinal belt 30–60°N. The year-round-, as well as the summer- and the winter data have been analyzed to detect year-to-year changes in the annual pattern of the probability density function of total ozone (PDFTO) in the belt. Long-term variations in the PDFTO have been deduced from trend analyses of the following statistical characteristics of the annual pattern of the PDFTO: mean, standard deviation, median, 10 and 90 percentile, and the asymmetry coefficient. The trends have been calculated from a multiple regression model adjusted for serial correlations, the 11-yr solar cycle, and long-term stratospheric circulation fluctuation effects. We have found that the pattern of the PDFTO has been drifting uniformly (without changes in its shape) towards lower ozone values, with some seasonal peculiarities in the drift (the annual rate of total column ozone loss). The winter pattern of the PDFTO moves (with a drift of 2.3% per decade) towards lower ozone values faster than the year round pattern (drift equals 1.8% per decade) and the summer pattern of the PDFTO (drift equals 1.5% per decade).     

Osteological features associated with ankle hyperdorsiflexion

The habitual adoption of certain gestures and postural habits can result in a variety of non‐metric traits, including supernumerary facets that are both articular and non‐articular. The squatting facet is a classical example of the former, and generally presents as a lateral articular facet on the neck of the talus that articulates with a facet on the anterior border of the distal tibia. These facets arise owing to the adoption of the squatting position and the hyperdorsiflexed position of the ankle joint, bringing the talus and tibia into immediate approximation. This study reports on the difference between the classical squatting facet and a non‐articular facet, which can also present on the neck of the talus but occurs, probably, as a result of soft tissue pressure, rather than bony articulation. It is suggested that whilst the function of the two facets may be similar, their aetiology is likely to be very different. Copyright © 2001 John Wiley & Sons, Ltd.     

Day-to-day variability of riometer absorption

Statistical variations of absorption data measured with a riometer on different days at a given hour are examined. Parameters of the cumulative amplitude-probability distributions are selected and the approximate relationships between these that have been found in earlier investigations are reviewed. A new mean relationship is derived from a study of an exterrded data set and its applicability to morphological mapping is considered.     

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.     

Do temporal size differences influence species identification of archaeological albatross remains when using modern reference samples?

Zooarchaeological remains have been identified to species, using identification criteria based on specific morphological variations among modern specimens. However, temporal size changes in bones, due to micro-evolution and/or phenotypic plasticity, could distort identification of archaeological remains according to these criteria. We developed species identification criteria for North Pacific albatrosses (Short-tailed, Laysan and Black-footed Albatrosses) using both mensural- and DNA-based analysis and actually identified many archaeological remains from a site using these criteria. Our mensural-based criteria could accurately discriminate the modern Short-tailed Albatross from modern Laysan and Black-footed Albatrosses and indicated that the archaeological remains included both Short-tailed and Laysan or Black-footed Albatrosses. DNA-based criteria, however, suggested that all remains were Short-tailed Albatross. The most plausible explanation for this inconsistency would be misidentification using mensural-based analysis, due to temporal size changes in bones or existence of birds from extinct population(s) or breeding region(s) with mensurally different bones from recent birds. This is the first study that suggests temporal size changes in bones may distort the species identification of archaeological remains according to modern size variations. Further studies are required to judge if this pattern is unusual or not.     

Solar cycle variation of the total electron content around equatorial anomaly crest region in east asia

The monthly mean hourly values of total electron content data obtained at Lunping Observatory (geographic coordinates 25.00°N, 121.17°E; geomagnetic coordinates 14.3°N, 191.3°E) by using the ETS2 satellite beacon signal during the period from March 1977 to December 1990 have been used to analyze the solar cycle variations of total electron content (TEC) around equatorial anomaly crest region in East Asia. Positive, correlations were found between the 12 month running average of monthly mean TECs and sunspot numbers. By using the linear regression analysis method, the contour charts for real diurnal and seasonal variations of TEC at certain sunspot numbers were constructed and described. The diurnal variation of TEC was represented by the sum of its diurnal mean and first three harmonic components. The solar cycle variations of these components have also been discussed.     

Influence of porosity on lipid preservation in the wall of archaeological pottery

Porosity of archaeological pottery is a key parameter used to assess its ability to trap lipids during the use of the pot and to preserve them over time. Mercury intrusion porosimetry and gas chromatography were used to study the distribution of porosity and the preservation of lipids in different chrono‐cultural contexts. The data obtained show that the porosity pattern, related to the raw materials and the savoir‐faire of the potters, influences the amount of lipids accumulated in the pottery. A significant overall porosity together with a high level of small pores is generally favourable for the preservation of lipids, but variations related to the environmental context are observed.     

Multi-scale tribological analysis of the technique of manufacture of an obsidian bracelet from Aşıklı Höyük (Aceramic Neolithic,Central Anatolia)

Tribological analysis is employed in a pilot study of the technological steps involved in the manufacture of a polished obsidian bracelet from A??kl? Höyük, an Aceramic Neolithic site in Central Anatolia (8300–7500 cal. B.C.). The study includes morphological analysis of the bracelet, based on profile measurements, and identifications of wear variations indicated by surface topographic features and parameters. The manufacturing skill that is revealed suggests early appearance of a regional tradition of obsidian working, which reached its full development in the 6th millennium cal. B.C. with the production of various ornamental objects, including mirrors and vessels. The cultural record and location of A??kl? Höyük make the site important for our understanding of the technological developments during the early Neolithic in Anatolia.     

Social Centers in Southern Italy: The Caserta Ex‐Canapificio Between Illegality,Migration, and Rurality

From the 1980s to the 1990s, squatting for Social Centers (Centri Sociali) has developed as radical left activists engaged in occupying empty buildings all over Italy. While most of the occupations happened in big cities in the Centre and North of Italy, this paper examines the peculiarity of the Social Center Ex‐Canapificio, located in a medium‐size city of an agricultural plain of Southern Italy. More specifically, three particular points are discussed. First, I show how the Social Center has been able to produce access to rights in a context of informality and illegality. Then, I analyze how the Social Center has allowed the setting up of an original social movement fighting for the rights of the poor immigrant workers living in the Campanian Plain. Finally, I enlighten how Ex‐Canapificio's activists have promoted new strategies to succeed in their struggles, despite their geographical distance from the main center of powers. In brief, this paper provides several themes of discussion about the spatialities of squatting and social movements.     

Functional-adaptive features and palaeobiologic implications of the postcranial skeleton of the late Miocene sabretooth borhyaenoid Thylacosmilus atrox (Metatheria)

A functional-adaptive study of the postcranium of two late Miocene sabretooth borhyaenoid specimens (Mammalia, Metatheria) is presented. Thylacosmilus atrox developed a longer neck than in non-sabretooth borhyaenoids and was capable of strong flexion of the head. The lower back is well-stabilized and more rigid than in the other borhyaenoids. The forelimb appears well-suited for manipulating and capturing prey, with a probably well-developed deltoid and pectoral musculature. Compared with other Miocene borhyaenoids, the hip joint of Thylacosmilus is modified to allow greater postural flexibility (e.g. possibility of erect stances). The low greater femoral trochanter, the short and sigmoid tibia, and the semiplantigrade hind foot of Thylacosmilus precluded fast running. Thylacosmilus killed by stabbing, a peculiar mechanism that evolved in parallel in many other sabretooth taxa. This technique has significant functional-adaptive consequences on the postcranial skeleton, superimposed on the generalized morphological pattern reflected in its non-sabertooth relatives. The superficial similarities observed between Thylacosmilus and Smilodon overshadow real differences (at the level of joint patterns and muscular groups involved in particular movements), a condition that suggests the development in the marsupial form of a morphological type unique to the thylacosmilid lineage within Borhyaenoidea.     

A Micro Computerized Tomography (X-RAY MICROSCOPY) of the Hand Phalanx of the Denisova Girl*

In 2010, the complete mitochondrial genome of a fossil hominin from Denisova Cave, Altai was sequenced on the basis of mtDNA extracted from the hand phalanx of a girl. Modern micro tomographic techniques mark a new stage in the morphological study of extant and fossil hominins, offering opportunities to work with fragmentary material. We have used the nondestructive method of micro computerized tomography for a comparative histological assessment of the Denisova girl's biological age. The diaphyseal and metaphyseal parts of the phalanx, reflecting different ontogenetic stages, were undergoing rapid growth. The histological pattern of the walls of the diaphysis, specifically the lamellar structure with rare osteons, indicates a stage corresponding to 6–7 years in modern children. An altogether different pattern, resembling that of adults, was earlier observed in a Neanderthal child from Okladnikov Cave, Altai. The resemblance between the Denisova individual and extant humans in certain features of growth and skeletal maturation may point to the very early origin of the modern skeletal growth pattern. The Neanderthal pattern is quite distinct and may have originated after these hominins had branched off from the common stem.     

Variability in bifacial technology at Elandsfontein,Western cape,South Africa: a geometric morphometric approach

This study applies a new three-dimensional measurement technique to determine the major source of variation in the Acheulian bifacial tool collection from the Middle Pleistocene site of Elandsfontein, South Africa. This three-dimensional technique is compared with conventional two-dimensional methods to investigate which methods capture morphological variation in the assemblage most comprehensively. Additionally, a set of experimentally produced bifacial tools are incorporated into the analyses to isolate the behavioral pattern underpinning identified variation in the archaeological assemblage. The interpretative breadth of current models explaining morphological variation in bifacial tools is then tested against the pattern identified in the Elandsfontein assemblage. Variation appears to be related to the consistent application of a specific reduction strategy associated with the early stages of bifacial tool manufacture. The intensity with which this strategy was applied seems to have been mediated by the availability of raw material that was suitable for the production of large bifacial tools.     

Description,significance and frequency of the acetabular crease of the hip bone

The acetabular crease is a linear indentation located in the antero‐superior quadrant of the surface of the acetabulum at the level of the Byers Feature 17. Considered by palaeoanthropologists as a discrete trait, it has received scarce attention and the mechanisms underlying its formation and variations according to sex and age remain largely unclear. The purpose of this study, carried out on a large sample from a historic population in France, was to (i) analyse variations according to side, sex and estimated age at death; (ii) assess diachronic variations; and (iii) compare prevalence in various prehistoric and historic populations. Hip bones from a total of 425 subjects of both sexes and all ages were studied. Specimens were from two French historic samples dating from the 11th to 13th centuries and 16th to 17th centuries. The proportion of subjects that died young was higher in the 11th to 13th century group, but the prevalence of the acetabular crease was comparable between the two groups regardless of site or laterality (unilateral or bilateral). No sexual dimorphism or correlation with age was noted at either period. The acetabular crease appears to be a stable anatomical trait throughout adult life, with no predominant side and no correlation with sex. The significantly higher prevalence of the acetabular crease in some historic French samples and in prehistoric native Canadian populations could be linked to greater biomechanical stress during childhood in rural medieval populations and in the prehistoric period.

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.     

A Test of the Effectiveness of the Coimbra Method in Capturing Activity‐induced Entheseal Changes

The current paper tests the effectiveness of entheseal changes in expressing activity patterns when the former have been recorded using the new Coimbra method. Changes on the subscapularis and biceps brachii were recorded using the Coimbra method on 78 men from the documented Athens Collection. Generalised linear models were adopted with entheseal changes as dependent variable and cross‐sectional geometric properties, age and body mass as predictors. The results suggest that age is the factor most frequently affecting entheseal changes; however, its impact is not as systematic as found in previous studies. Body mass is rarely statistically significant, again contradicting earlier studies. Finally, activity proxied by cross‐sectional geometric properties is occasionally significant, but no clear pattern emerges that can associate specific entheseal morphological changes with specific directions of mechanical loading.

Day-to-day variations in nearshore bar patterns on a small sandy beach through a lunar tidal cycle

Nearshore water circulation and bar patterns at Coledale, New South Wales, were surveyed daily over thirty-six consecutive days, from 3 November to 8 December 1978, to identify sequences of changes that might occur in response to spring-to-spring tide cycles of fourteen days, changing barometric and wind conditions associated with the passage of anticyclonic weather systems across the coast, and day to day variation in the nearshore wave regime. During the survey the bar patterns tended to vary from transverse bars, through a composite arrangement incorporating longshore and transverse bars, to a longshore bar pattern as the tide changed from its spring to neap tide phase. However, this sequence was too brief to unequivocally establish variations in nearshore bar pattern that might be attributed to the fourteen day, spring-to-spring tide cycle. Nevertheless, morphologic changes occurring in response to wave regime fluctuation at Coledale were broadly in accord with studies from elsewhere by Dolan et al. (1979, 1982), and Clarke and Eliot (1982, 1983) in that bars and rips were systematically distributed along the beach. At Coledale, bars tended to relocate approximately 0.4 and 0.75 of the distance along the beach from its southern end. The preferred bar spacing closely matches hypothetical standing waves trapped between the headlands of the Coledale embayment. Temporally, the nearshore morphology is highly responsive to wave regime changes such that, as primary breaker heights decrease and remain below H_max=1.0m, the bar pattern changes from longshore through mixed to transverse bar patterns within three to five days. On one occasion the bar pattern switched from a longshore to a transverse bar pattern within twenty-four hours.
