Occlusal molar microwear and the diets of the Ipiutak and Tigara populations (Point Hope) with comparisons to the Aleut and Arikara

Archaeological excavations at Point Hope, Alaska uncovered skeletal remains of two populations: the Ipiutak (100 B.C.–500 A.D.) and Tigara (1200–1700 A.D.). Archaeological evidence indicates that, although both groups relied on animal (largely marine) resources for their subsistence, the Ipiutak were mainly caribou hunters, whereas the Tigara were primarily whale hunters. To date, no study has attempted to ascertain whether the inferred dietary differences of these two groups could be substantiated using a more direct technique, e.g. microwear or stable isotope analysis. In this study, the occlusal molar microwear fabrics of the Ipiutak and Tigara were analyzed. Comparative data for two other modern human groups, the Aleut and Arikara, were also examined. Significant differences in microwear signatures were detected among the groups considered. The results of this study show that the Tigara have significantly more microwear features, more pits and narrower scratches compared to the Ipiutak. These results are concordant with interpretations that the two Point Hope populations had significantly different dietary habits. Differences in microwear signatures between the Aleut and the two Point Hope populations were also detected. Compared to the two Point Hope populations, the Aleut has significantly fewer features and wider scratches. The Aleut microwear signature further differs from that of the Tigara in having significantly lower pitting incidence. The microwear pattern of the Arikara, who had a mixed diet, differed from that of the mainly meat-eating Aleut and Point Hope peoples in that the Arikara has significantly fewer features, lower pitting incidence and narrower scratches.     

Temporal changes in Arikara humeral and femoral cross-sectional geometry associated with horticultural intensification

Humeral and femoral cross-sectional properties from three archaeological variants of the Arikara, an American Great Plains Indian tribe, were analyzed for temporal (16th to 19th centuries) changes in long bone architecture, asymmetry, and sexual dimorphism associated with intensification of horticulture during the late protohistoric and early historic periods. There were a number of significant changes in long bone, especially femoral, cross-sectional morphology and asymmetry among females through time that probably reflect increases in the workload necessary to produce surplus crops. Changes in long bone architecture among males are restricted to the humerus and may reflect a greater reliance on firearms. The pattern of sexual dimorphism also changes through time among the Arikara due to a combination of environmental (nutrition and disease) and mechanical factors.     

‘Parry’ fractures and female-directed interpersonal violence: Implications from the Late Archaic Period of west Tennessee

The recognition of a high frequency of ‘parry’ fractures in the females from the Late Archaic Period (2500–1000/500 BC ) west Tennessee site of Eva prompted a more thorough examination of female-directed interpersonal violence in prehistoric Tennessee sites. The study examined forearm fractures in eight (N = 308) Late Archaic Period hunter-gatherer sites and five (N = 501) Mississippian Period (c. AD 1200–1600) agriculturalist sites. On the basis of chi-square test results, there does not appear to be any gender bias in forearm fracture occurrence in the Archaic Period. The high frequency of female ‘parry’ fractures at Eva was an artefact of the ratio of females to males. More importantly, craniofacial trauma data do not support an aetiology that would explain mid-shaft forearm fractures as a result of interpersonal violence.     

PARKOUR: CREATING LOOSE SPACES?

Parkour is a spectacular and highly mediatized new way of movement that challenges conceptions of acceptable or appropriate behaviour in urban public space. This article will examine the potential of parkour to “loosen” urban spatial texture by applying recent thinking on loose and tight space by Karen A. Franck and Quentin Stevens to data gathered through in‐depth interviews with parkour practitioners (traceurs) in two Finnish cities. When practising in urban public spaces, the traceurs we interviewed often caused confusion among other people. We explore how they negotiate their right to public space in the face of these reactions, either by evasion or with a combination of legal and moral arguments. We argue that parkour is not only a playful and confrontational practice with a potentially subversive character, but that the process of loosening space constitutes a complex dialectic, which may also involve a certain degree of tightening in the public space for other unexpected or unintended activities.     

人文地理学空间思想的几次重大转折

理解空间思想的演变及其与人文地理学的关系具有重要意义。从思想史角度出发,可将人文地理学空间思想的演变划分为起、承、转、合四个阶段。康德从哲学角度第一次系统地界定地理学为专门的空间科学,抬升了地理学的学科地位。赫特纳-哈特向承袭康德的空间观,将空间科学的抽象规定与方志传统的实际历史结合,把地理学研究对象归约为区域。其后,人文地理学的空间思想出现了四次重大转向,分别是空间几何学、人文空间性、激进的空间、空间的生产;它们体现了人文地理学与数学、哲学和其它社会科学的紧密关联与交叉。20世纪80年代以来兴起的后现代空间思想某种程度上契合康德空间观,但在哲学理念和侧重点上存在很大差异。由于不同空间认识论都有其价值,价值大小也难以评估,所以人文地理学学科地位与身份问题的争论已趋于淡化,这提示了人文地理空间研究可采取多重面向。哲学和其他学科在为人文地理提供依据和工具,使得人文地理学身份陷入迷离的同时也为其增添了活力和魅力,这是人文地理学面临的最大机遇与挑战。     

从地理空间到复合式空间--信息网络影响下的城市空间

分析了城市在地理空间、网络空间上存在的相互依赖关系以及这二者之间复杂作用关系,说明网络空间并非地理上城市空间功能的简单延伸,也并非现实空间的简单镜像;信息社会的城市空间是一种地理空间与网络空间相互依存、相互交织的复合式空间。城市空间仍然具有重要的地理学意义,地缘上的差异以新的方式体现出来。

(Re)Producing and challenging gender in and through urban space: women bicyclists’ experiences in Chicago

This research, which uses an intersectional feminist methodological approach, explores the relationships and intersections among women, public urban space, and bicycling, and the gendered processes through which the use of space is claimed, negotiated, and constrained. It builds on the existing scholarship on the gendered nature of public space, and uniquely uses bicycling as the site of inquiry. Drawing primarily from interviews with women cyclists in Chicago, this article explores how gender and other social identities are constructed, challenged, and constituted through an interaction with public space, urban processes and structures, and societal expectations and attitudes. It brings to the forefront and centers these narratives and empirically contextualizes them by linking the scholarship on the gendered (and raced, classed, and sexualized) nature of public space with the scholarship on women’s participation rates and barriers to bicycling. This research examines, through the everyday lived experiences of bicyclists and their multiple subject positions and privileges, how the gendered nature of public space affects the participation and experiences of women cyclists; how public space is negotiated and constrained; and how gender can be both (re)produced and challenged in and through urban space via women bicyclists’ actions. In particular, the research findings explore how women bicyclists must demand and negotiate public space; how their movement and activities are constrained in public space; how gender roles and social reproduction issues intersect with bicycling; and how social, quasi-advocacy group bicycle rides are used as a strategy, with mixed results, to address barriers to women bicyclists’ mobility.

“非正常”的文化标签下“同志”社会空间的生产——以广州市X公园“同志渔场”为例

性少数群体对于城市空间的利用是城市研究中的新兴话题。这类研究主要探讨\"非主流\"的社会身份如何通过对特定的社会空间的利用,引发空间意义的生产及社会关系的建构。本文以广州市X公园的\"同志渔场\"为案例,研究男同性恋者对于城市公共空间的利用与体验。研究认为,X公园的\"同志渔场\"不仅给性少数群体提供了性身份暂时解放的空间,亦是其不断体验自身\"非正常\"的身份标签的空间。同志的空间实践体现的不是对于主流的社会规范的抵抗。相反,他们的空间实践是明显地处在\"非正常\"这一身份标签的作用之下的。

Analyses of measurements taken from adult femurs of a British population

The femur remains an important bone in palaeoanthropology and this paper reports various analyses of measurements taken from long-cassette radiographs of adult femurs of a reference population from the south of England (n=81, males 33, females 48). Discriminant analysis confirmed that the male femur is usually larger than the female femur, and that a femur may be sexed with some confidence. Discriminant scores have been derived to permit estimates to be made, from the whole or a part of a femur, of the probability of the male gender. Outcomes from a principal component analysis suggest: that the female proximal femur is a morphological unit; that neck length and shaft length are dissociated and there is no common factor representing linearity; and that the male bicondylar width is anomalous, a finding that is confirmed by other analyses. An estimate of the robusticity of the complete female, but not male, bone may sometimes be made from a proximal fragment. The robusticity of the complete bone may be made confidently from the shaft for both genders. The two width variables relating to a distal fragment cannot be used to predict the robusticity of the complete bone for either gender. A method of defining the position of the waist in terms of displacement in deciles down the shaft is described. The position of the waist seems to have a bimodal distribution. The positive association between age and distal displacement may be due to remoulding of the shaft with age or to a cohort (generational) effect. There is a weak correlation between a small neck–shaft angle and the distal displacement of the waist, two archaic phenotypic traits. Ten statements in the literature relating to the femur have been examined and tested; six are confirmed and four are unconfirmed, and it is suggested that there is a need for further studies relating to the morphology of the femur.     

Gender and Mahalle (Neighborhood) Space in Istanbul

Studies of gender have an important place in studies of Turkey because the discourses of Islamism and secularism, and modernity and tradition, make the bodies and practices of Turkish women the site of debate. However, few studies have used a spatial analysis to examine the production of gender in daily life. This article is simultaneously a study of how gender is produced through space and of the creation of various kinds of spaces in an Istanbul mahalle (neighborhood). The mahalle is the space of intimate daily life in the Turkish urban context, and narratives of and ways of life in the mahalle articulate competing notions of what it means to be a woman in Turkey. This study of gender and mahalle space reveals the linkages between space and gender to be multiple and shifting and the boundaries between private and public spaces to be fluid. Furthermore, this reading of gender and urban space, when brought back to the Turkish context, also contributes to research which interrogates the idea of modernity at the core of national identity in Turkey, of which gender is a central and constitutive element.
