Abstract

Politics and Passion corrects liberal theory that conceives politics as rational deliberation among autonomous individuals who voluntarily associate in groups to advance their chosen life plans. Freedom and equality for individuals, insofar as they can be approximated, depend, Walzer contends, on passionate political activity and state policy that empower marginalized and diverse groups. Ethical principles and democratic deliberation are insufficient for group politics. Theological ethicists should welcome and learn, once again, from Walzer. However, a liberal conception of justice that avoids naiveté about individual autonomy and democratic deliberation should have a greater role in politics, even the politics of group pluralism and equality, than Walzer apparently permits. Respect for the dignity of individuals requires it.  相似文献

The assumption of natural selection for obstetric adequacy would predict the occasional discovery of skeletal evidence for inadequacy, yet such cases are rare. Here stress injuries to the pelvic ring are associated with an asymmetrical pelvis caused by partial agenesis of the right sacral costal process. The small, middle‐aged woman lived about 2000 years ago and pursued a physically vigorous life as a coastal forager on the South African Cape coast. The right sacral costal process (ala) is about 5 mm narrower than the left. This sacral hemiagenesis led to pelvic asymmetry, and concomitant instability. The six articular faces of the pelvis show the normal surfaces replaced by disorganised, porous new bone and extensive eburnation. The left pubic face shifted dorsally, making contact with the ventral aspect of the right pubis. The most distinctive aspect is the presence of osteitis pubis, or pubic symphysis stress injury, which is clinically associated both with difficult childbirth and with vigorous athletic activities. Adjustments to the altered pelvis include erosions and osteophytes at sites of ligament attachment, and prominent bilateral insertion areas on the tibiae for the stabilising iliotibial band. While habitual activities may explain some pelvic features, such as the bilateral bevelling of the acetabular borders, it is postulated that childbirth exacerbated the joint instability and the subsequent deterioration. This case joins a small literature on the condition of pubic symphysis stress injury, and illustrates the mechanisms through which natural selection for pelvic size and shape characteristics may have occurred.

This paper refers to an investigation of finds that are associated with the raw materials and tools for the preparation or use of lead pigments at Akrotiri on Thera, Greece, during the Early, Middle and Late Cycladic Bronze Age (c. 3000–1600 BC). For the detection and the preliminary characterisation of remains of pigments that were found on stone tools, the in situ application of X-Ray Fluorescence spectroscopy proved to be invaluable. In order to identify the chemical composition of the pigments and to investigate their provenance from a geological perspective, quantitative X-Ray Diffraction analysis was conducted. A thorough visual macro and microscopic examination of the morphology of the materials permitted the determination of physical features (colour, homogeneity, grain size) as indicators of their nature or degree of processing. Based on the results of these analyses, the traces of lead oxides that were detected on the stone tools are associated with specific collections of litharge items discovered at the settlement of Akrotiri, and probably provide evidence of their earliest use in preparing pigments.  相似文献

The aim of this paper was to determine what technical gestures must be learned in order to produce stone tools. To identify these gestures, we compared the performance of expert knappers and complete novices. We hypothesised that the differences between novices and experts would indicate which technical gestures experts had learned to successfully produce stone tools. Participants were video recorded while attempting to produce a crude handaxe. The recordings were analysed according to ethological methods used to study animal and human behaviour. The knapping performance of each participant was segmented and scored into units in order to identify the technical gestures being used. The results showed considerable differences between experts and novices in three technical gestures: the type of percussion support, the position of the blank and the angle of blow. Therefore, these three technical gestures appear to be crucial in learning to knap stone at the level of bifacial stone toolmakers. By studying how modern knappers gradually master these three technical gestures we may begin to understand how stone knapping is acquired, how bifacial stone tools emerged and what cognitive challenges early handaxe makers had to face.  相似文献

An extensive experimental program was carried out at EUCENTRE, within a research project on the evaluation and reduction of the seismic vulnerability of stone masonry structures. The main part of the experimental program has been devoted to the shaking table tests on three full-scale, two-story, single-room prototype buildings made of undressed double-leaf stone masonry. The first building tested was representative of existing unreinforced stone masonry structures with flexible wooden diaphragms, without any specific anti-seismic design nor detailing. In the second and third buildings, strengthening interventions were simulated on structures theoretically identical to the first one, improving wall-to-floor and wall-to-roof connections and increasing diaphragm stiffness. In particular, in the third specimen, steel and r.c. ring beams were used to improve the diaphragm connection to the walls and collaborating r.c. slab and multi-layer plywood panels were used to stiffen floor and roof diaphragms, respectively. This article describes the strengthening interventions applied to the third building prototype and presents the experimental results obtained during the shaking table tests. The results obtained permitted the calibration of a macroelement model representative of the nonlinear behavior of the structure.  相似文献

Sustainability in the conservation of architectural heritage is now more extensively considered than it was decades ago. The introduction of the concept of sustainability to the field marked hopes to overcome problems threatening heritage sites. There are general concepts guiding sustainable conservation. However, heritage specifics play important roles in achieving sustainability, and may direct the formulation of sustainable concepts to be applied. This paper is an attempt to add to the discourse of heritage sustainability by discussing buildings managed through a tradition of Islamic waqf in the World Heritage Stone Town of Zanzibar. It examines sustainability in terms of its financial, social, managerial, and environmental aspects. The relatively good survival rate of waqf buildings in the old town over several centuries suggests sustainable and transmissible ‘genes’ within the tradition. Waqf was found to elaborate ways to strike a balance between heritage consumption and use, avoiding gentrification, and enabling collective urban conservation. It further suggests that sustainable conservation cannot avoid monetary sacrifices, and if it is to be sustainable in the long term it should be inherent in the heritage itself.  相似文献

Heritage stone buildings are typically vulnerable to seismic events. Results of an experimental program were analyzed to evaluate the shear strength and intrinsic damping of stone masonry representative of the West Block of the Canadian Parliamentary Precinct in Ottawa. Eight representative wall specimens with different rehabilitation schemes had been tested under different static and dynamic loadings. Each wall had wythes of sandstone and limestone connected by a rubble core. The results show the shear strength of the walls could be predicted accurately and that no strengthening scheme was particularly beneficial. The effective viscous damping ratios varied between 7 and 9%.  相似文献

Abstract

Itaakpa rockshelter was excavated in three short field seasons, from 1985 to 1988, during which a human maxilla and mandible were found in a context characteristic of the ceramic phase of the West African Late Stone Age (LSA). An AMS date of 2210±80 b.p. was obtained from burned palm kernels from the same level. There was no apparent stratigraphic or archaeological break between this level and the layers above, and the pottery indicates continuity of occupation; the upper part of the sequence compares well with other, more recent, sites known in the area. The dimensions of the human teeth show an affinity with those found at Shum Laka, a rockshelter in southwestern Cameroun, in an archaeological context similar to that at Itaakpa. The site is only the third to be found in Nigeria (along with Iwo Eleru and Rop Rockshelter) where human remains suitable for comparative analysis have been identified in a good stratigraphic context along with LSA artifacts.  相似文献
