The relationship between forming techniques and orientation of the components of ceramic materials in the context of pottery technology has long been recognized and used for identification of the techniques employed to create archaeological ceramics. The alignment of inclusions is usually characterized by qualitative categories or ordinal scales. This paper evaluates the potential of quantitative orientation analysis for identification of pottery‐forming techniques. A collection of experimental pottery formed using five forming techniques and combined techniques was analysed. The forming techniques were characterized by the intervals of the mean direction and the circular standard deviations of the orientation of the major axes of the ellipses equivalent to the objects representing random sections of inclusions and voids. The most informative criteria for the identification of pottery techniques are the circular standard deviation of the inclusion/void orientations in the core area of the vessel wall in a perpendicular thin section and the mean direction in a tangential section.  相似文献

The paper presents an algorithm for computing the parameters of an ellipse that fits, in a least-squares sense, the surveyed remains of Roman amphitheatre arena walls. The algorithm is validated using ideal data and the near complete remains of the amphitheatre at Sarmizegetusa in Romania. The technique is then applied to the partial remains of the amphitheatre at the Guildhall in the City of London, in the UK, which cover only the Eastern end of the monument. The underlying mathematical model and method of solution is presented. The method was developed with a view to determining firstly whether or not an ellipse is a feasible model for the actual constructed curve geometry, and secondly, where the Western end of the Guildhall amphitheatre might be located. One single ellipse was found to fit the Guildhall remains, with measurement residuals at the level of 30 mm in the eastings and 26 mm in the northings. The ellipse had a semi-major axis of 28.345 m and a semi-minor axis of 22.775 m. The issues of alternative geometries and the practicalities of their use in construction are considered.  相似文献

This article engages with Frantz Fanon's writing on both geographical and dialectical movement. It suggests that in particular historical-geographical contexts—such as those described by Fanon himself—geographical patterns of mobility and confinement operate as the presupposition and result of “race”; while also functionally enabling capitalism's necessary and enduring dialectic of appropriation and capitalisation, and reproducing the Fanonian “zone of nonbeing”. More simply, this article suggests that in certain conjunctures the tight articulation of race, mobility, and capital accumulation inhibits the reciprocal recognition of equals. In those contexts, a spatialised “counter-ontological” politics is the only means of establishing intersubjective symmetry and the preconditions for Fanon's “new humanism”. This article concretises these arguments in relation to historical work on antebellum “carceral landscapes”. It concludes by drawing explicitly on Stuart Hall's reflections on articulation and “lines of tendential force” in order to think through the relevance of Fanonian theorisation today.  相似文献

Following are fragments of a book devoted to theoretical geography on which Professor Smirnov, head of the Department of Economic Geography of Odessa University, was working at the time of his death in July, 1969. An attempt is made to formulate a system of general geographic concepts that would constitute the axiomatic foundation of geography. Several types of fundamental concepts are distinguished: spatial concepts; concepts of the structure and functions of geographical formations; concepts of simple and complex formations, etc. The present paper is limited to an examination of spatial concepts associated with geographical space, which is viewed as one of the general properties of geographical formations. Three basic spatial concepts are discussed: (a) the concept of group space, meaning the space occupied by a set of interrelated objects, as opposed to the individual space of a single object; (b) the concept of spatial integration of phenomena, implying causal relationships; (c) the concept of geographical commonality of phenomena, as opposed to the theory of uniqueness or local exclusiveness. The interplay of general laws and purely local relationships gives rise to a spatial field of interaction known as the geographical field. A geographical formation and its field of interaction may be centered, as in urban settlement, industry and other nodal phenomena, or they may be noncentered, as in rural settlement, agriculture and other spatially continuous phenomena. Other concepts are the area, shape, orientation and spatial dynamics of development of geographical formations.  相似文献

The author traces the evolution of the environmentalist concept through Marxist philosophy and analyzes the influence on the geographical environment on society. He adduces a number of examples to demonstrate the significance of the environmental factor in various historical contexts. For another discussion on the same subject, the reader is referred to Ian M. Matley, “The Marxist approach to the geographical environment,” Annals of the Association of American Geographers, Vol. 56, No. I, March 1966, pp. 97–111.  相似文献

In this paper I examine reactions to the Greenham Common Women's Peace Camp. I argue that the media, local and government responses to the Greenham women reveal geographical assumptions about “normality.” The peace women, by living away from home, on the edge of a military (and therefore masculine) establishment challenged accepted patriarchal understandings of “women's place” and were thus described as “out of place.” More specifically, the women were referred to in terms of hygiene, inadequate culinary ability, sexuality and hysteria. Each of these implies a gendered form of disorder in which social, cultural and geographical boundaries have been transgressed. These reactions are placed within the context of Bakhtin's formulations of the carnivalesque and grotesque realism. I suggest that the women, through their highly visible opposition to a patriarchal military establishment, represent a threat to neatly bounded official culture which finds its geographical expression in the formal territories of the courtroom and the air base. In conclusion this illustration is placed in the wider context of cultural/political protest. I argue that transgression, while serving to reveal normally assumed hegemonic landscapes, is restrained by already existing boundaries.  相似文献

Abstract

Mainstream geographical information systems techniques and packaged geographical information systems software are often inappropriate in historical contexts because they use geographical coordinates as a framework around which all other information is organized as “attribute data,” whereas in history locations are often the least certain part of our knowledge. A new and general architecture for documenting administrative units and organizing historical statistics is detailed, which prioritizes named entities and explicit semantic relationships such as “IsPartOf,” while holding coordinate data where available. This architecture is easily aligned with the recent development of geo-semantics by information scientists, meeting the formal requirements for a geo-spatial ontology, but was originally developed to enable the systematic computerization of traditional historical reference works, notably Frederick Youngs’ Guide to the Local Administrative Units of England.  相似文献

This article discusses options to allow comparative analysis of inequalities in the distribution of health workers (HWs) across and within countries using a single summary measure of the distribution. Income inequality generally is measured across individuals, but inequalities in the dispersion of HWs must use geographical areas or population groupings as units of analysis. The article first shows how this change of observational unit creates a resolution problem for various inequality indices and then tests how sensitive a simple ratio measure of the distribution of HWs is to changes in resolution. This ratio of inequality is illustrated first with the global distribution of HWs and then with its distributions within Indonesia. The resolution problem is not solved through this new approach, and indicators of inequalities of access to HWs or health services more generally appear not to be comparable across countries. Investigating geographical inequalities over time in one setting is possible but only if the units of analysis remain the same over time.  相似文献

The value and limitations of mammalian fossils as biostratigraphic indicators in the Pleistocene are discussed. Aspects of a species' history which are of potential biostratigraphic value are its overall stratigraphic range, shifts in geographical distribution, evolutionary transitions, and changing abundance in the fauna. These form a complex pattern which must be established in some detail before a species can be used in dating a “new” locality. The major features of stratigraphic range, distributional history, and evolution of each of the nine species of cervid from Britain and mainland Europe during the Middle and Upper Pleistocene are outlined, with notes on their possible biostratigraphic value. Some new results on the deer remains from Swanscombe are presented. Fallow deer can be referred to subspecies Dama dama clactoniana only in the Basal and Lower Gravels and Lower Loam. There is no evidence of change in its body size within the sequence. An idiosyncrasy in the lower dentition of Swanscombe fallow is described. The red deer was the “coronate” form, and was of small body size. The giant deer was of small body size, and may have shared the broad brow tines of the Steinheim population. Roe is rare and elk is absent. The Swanscombe deer suggest a post-Cromerian, interglacial dating of all faunal levels at the site. They are consistent with a wholly Hoxnian age, but precise contemporaneity with Hoxne Bed 1 is unlikely, and the possibility of additional stages being represented cannot be excluded.  相似文献

A group of physical geographers of the Institute of Geography in Moscow, the principal academic research institution in geography, published an article in 1974 seeking to define and categorize terms and concepts now being used in Soviet geography. The article said the term geosystem (geographical system) applied equally to physical-geographical and socio-economic entities, and the term “geographical environment”, in actual research practice, referred not only to the physical setting of human activities, but also to engineering elements and social conditions. The present writer contends that such a definition of the geographical environment, incorporating both natural and social elements, smacks of a unified geography, and that geosystems, as originally defined, refer only to natural terrestrial systems, excluding man.  相似文献

Summary. A computerised search method is described to identify every possible rectangular structure within set parameters from post hole distributions. Results are obtained from a dense distribution within Danebury hillfort and tested statistically by comparison with results from simulations and a mathematical model. The most likely structures are isolated by analyses of size, shape and orientation. A further comparison, with the results of an independent visual analysis of the same area, allows some comment to be made on the efficiency of human pattern perception and the validity of existing preconceptions concerning rectangular post-built structures.  相似文献

We measure the effect of resource‐sector dependence on long‐run income growth using the natural experiment of coal mining in 409 Appalachian counties selected for homogeneity. Using a panel data set (1970–2010), we find a one standard deviation increase in resource dependence is associated with 0.5–1 percentage point long‐run and a 0.2 percentage point short‐run decline in the annual growth rate of per capita personal income. We also measure the extent to which the resource curse operates through disincentives to education, and find significant effects, but this “education channel” explains less than 15 percent of the apparent curse.  相似文献

There is now strong evidence that “soft” institutions are interrelated with the working of the economy. For example, in a geographical setting there is evidence that language borders affect interpersonal relationships, but there is no equivalent evidence regarding the effects of language borders on agglomeration or competition spillovers. This paper examines whether language affects the geographical extension of agglomeration and competition spillovers by observing the geography of employment patterns in a linguistically discontinuous setting. Our findings, for the first time, provide empirical evidence that language borders shape the distance decay of competition spillovers, independent of governance, and institutional issues.  相似文献
