Detailing spaces and processes of resistance: Working women in Dundee’s jute industry     

Emma M. Wainwright 《Geoforum》2007,38(4):688-697

Recent and ongoing calls within labour geography and social and cultural geography have highlighted the importance of resistance, its spatial productions and manifestations. However, within this work, the geographical history of the factory system has been largely overlooked. Drawing upon Foucauldian theorisings in the fields of management and organisation, together with recent writings on the geographies of resistance, this paper takes Dundee’s jute industry at the turn of the twentieth century as its focus and explores how the workplace itself, and the very workplace discipline used to ensure a productive, efficient and hardworking workforce, engendered workplace protest among the industry’s working women. Writing through a number of modes and scales of protest within the workplace, within and between work groups, departments, mills and factories, and across the city, this paper adheres to an approach that carefully details the spaces and processes of resistance, paying careful attention to how union and non-union resistances operated and the geographies they worked through and created.  相似文献

本文导出了一种给出相对烈度在lg R~0之间的收敛解(忽略震级)的小震方程式。结合在贝加尔地区岩石抗震特性调查与文字资料和统一理论,使人们可对震源等势面进行评估。确定了在震源区边界处的地震烈度稳定性和弹性波在地壳中的传播,使得推导出从地震主要参数震级向随震中距不同的烈度定量计算的转换成为可能。获得了烈度(能通量的密度)对距离的双线性相关,给出了能通量密度和相对烈度之间的关系。求出了取决于地表建筑地基的物理特性的振动载荷烈度。在地震学角度,这种强震的定量预测方法是一种提供详细地震区划和场地小区划的可能手段之一。  相似文献   

Correlation of cyclic preloading with the liquefaction resistance   总被引：1，自引：0，他引：1

The compactivity of sand due to cyclic loading with a high number (N>10³) of small cycles (ε^ampl≤10⁻³) cannot be described by void ratio and stress alone. It depends strongly on the soil fabric usually described as ‘cyclic preloading’. The cyclic preloading cannot be measured directly in situ but correlates well with the liquefaction resistance. This paper demonstrates this correlation on the basis of laboratory tests. Practical applications can be derived from this work.  相似文献   

考虑土体强度的建筑基坑突涌问题分析   总被引：7，自引：1，他引：7  

谭松林 《地球科学》2002,27(2):209-211,216

基于土体的强度特性，并假设突涌破坏体为方柱体或圆柱体，推导出了考虑土体强度的基坑突涌稳定性计算公式，计算结果表明，对于一般的粘性土， 考虑其强度后的抗力分项系数比不考虑强度的抗力分项系数增加二倍以上，汉口地区许多基坑开挖并没有出现突涌现象，表明土体的抗剪强度对抗力起着不可忽视的作用，因此考虑土体强度的突涌稳定性分析是比较接近工程实际的。  相似文献

Annual regime of bedforms, roughness and flow resistance, Lillooet River, British Columbia, BC     

Mariëtte T. H. Prent  Edward J. Hickin   《Geomorphology》2001,41(4):12

A field study to examine the statistical character of dune morphology and the correlation among dune morphology, discharge, and flow resistance was conducted in a meandering reach of Lillooet River, near Pemberton, British Columbia, Canada. The field season spanned the 1995/1996 hydrologic year with sample day discharge events ranging between 33 and 425 m³ s⁻¹. Surveys of the bed morphology along the thalweg in two dune fields (A and B) were completed using an echo sounder with chart recorder that enabled the measurement of more than 4000 dunes. Dune height ranged between 0.08 and 0.96 m, length between 2.01 and 20.99 m, and steepness between 0.02 and 0.10. Histograms of each dune shape (height, length, steepness) sample most often displayed positive skewness and non-Gaussian distributions (Gamma, Beta, and Weibull); median sample height and length histograms displayed positive skewness; and steepness was nearly Gaussian. Histograms of all dimensionless dunes (i.e., measurement divided by average measurement of sample) were Gaussian and slightly leptokurtic. Neither the height nor length of dunes measured in this investigation were successfully predicted by the empirical models of Allen [Allen, J.R.L., 1984. Developments in Sedimentology. Sedimentary Structures: Their Character and Physical Basis, 2nd edn. Elsevier, New York, vol. 30 (A and B), 1256 pp.], Fredsøe [J. Hydraul. Div., Am. Soc. Civ. Eng. 108(HY8) (1982) 932.], or Yalin [J. Hydraul. Div., Am. Soc. Civ. Eng. 90(HY5) (1964) 105.]. Least-squares regression models for dune–height relations produced here are similar to models published by other field researchers; regression models for dune length only conform to those developed elsewhere if the discharge of the study rivers was similar. The energy gradient in dune field A varied within a smaller range than in field B, enabling dune size to become more fully equilibrated with respect to flow environment. Although the average Froude numbers were much less than critical, dunes appeared to wash out towards a plane bed as discharge increased due to a change from a bedload to suspended-load dominated sediment-transport regime. Flow resistance increased most rapidly during changes in base flow and at the beginning and end of the seasonal flood; resistance tended to be smaller in field A than B, reflecting local differences in energy gradient. Flow resistance increased until a dune steepness of 0.070 was attained and then decreased. The steepness value was considered to be coincident with kolk generation [Dyer, K.R., 1986. Coastal and Estuarine Sediment Dynamics. Wiley, NY, 342 pp.], suggesting that macroturbulent flow structures play an important role in defining the roughness of dunes on a channel bed.  相似文献

LINKING SEDIMENT EXPOSURE WITH EFFECTS: MODELING TECHNIQUES, ORGANIC AVAILABILITY AND UPTAKE     

Xiaoxia LU  Danny REIBLE 《国际泥沙研究》2003,(2)

1 INTRODUCTION Sediments are the ultimate sink for many hydrophobic contaminants and represent biologically important environmental habitats. Exposure of the sediment-associated contaminants is not only influenced by the fate and transport of sediment but also is influenced by a variety of physical, chemical, and biological processes that involve no net movement of sediments. These processes include pore water transport processes such as advection and diffusion, and sediment mixing process…  相似文献
