This paper examines the embedding of information and communication technology (ICT) tools in everyday practices among underserved populations in urban India. Using ethnographic investigations of PC-aided micro- and small enterprises (MSEs) in a low-income slum neighborhood in Mumbai, it pursued three broad research goals: first, to etch out organic ICT immersions in underserved technology environments; second, to articulate a new and evolving socio-technical system in an urban slum ecology; third, to seek a fit between goals of ICT for development and impacts of PC-aided enterprise on ICT access and adoption. Based on the ICT4D 2.0 approach interrogating the technology-for-development discourse, this paper substantiates the need for a “new view of the world's poor: one that views the poor not as passive consumers but agile agents and innovative producers of ICT products and services.” 相似文献

The aim of this article is to show how Human Factors and Ergonomics (HFE) methods can be used to improve urban public infrastructure systems in densely populated countries, such as India. In this case, we use Accimap analysis with crowd flow approaches to inform safety and policy. We demonstrate the need for sociotechnical systemic safety by a case study of accident analysis of the Elphinstone Road railway station stampede. On September 29, 2017, the Elphinstone Road, Mumbai, India, railway platform bridge stampede killed at least 23 and injured 39 other commuters who traveled through the Mumbai Suburban railway. In this study, we understand the accident as it is presented in newspaper articles. We analyze the accident by a sociotechnical accident analysis method called the Accimap. The Accimap method helps by identification of various stakeholders and their interactions in the different levels of hierarchy in a sociotechnical system. This ensures moving away from individualistic and blame-based accounts of media reporting to a coherent sociotechnical account based on understanding the dynamics of the situation. The findings from the Accimap analysis identify the problem areas in the commuter transit system and provide recommendations. These recommendations range from commuter flow management to enforcement of rules for supporting pedestrian flow. The article concludes with an emphasis on the development of the sociotechnical dimension of public safety and infrastructure from a human factors perspective, above and beyond what is currently practiced in India. 相似文献

Reservoir sandstones in the Mid‐ and South Tapti gas fields in the Surat Depression (Mumbai Offshore Basin, western India) have been investigated using a range of petrographic techniques, isotope geochemistry and basin modelling. Authigenic chlorite is abundant in the shallow‐marine sandstones of the Miocene Mahim Formation, a major reservoir rock in the Mid‐ and South Tapti fields, which are described here in terms of their quality and diagenetic characteristics. The sandstones are currently at burial depths of between ~1500 and 2800m. The authigenic chlorite has had a significant impact on the resulting reservoir quality of the sandstones and is interpreted to have originated as odinite clay of the verdine facies that replaced faecal or pseudo‐faecal pellets, together with volumetrically small but abundant grain coatings and grain rims, and formed at the site of major riverine iron influx onto the shallow‐marine shelf during periods of relatively low sea level. Pellets have been variably compacted to form pseudomatrix. Reservoir sandstones from similar depositional settings on the west coast of India or other sub‐tropical settings are likely to exhibit comparable diagenetic effects on reservoir quality. Compositionally, the chlorite is the iron‐rich form known as chamosite. The chemistry of all the chlorite morphologies is the same in all studied samples. Oxygen isotope analyses of carbonate cements in the Mahim Formation sandstones have provided an approximate temperature framework for diagenesis of the non‐carbonate cements. Oxygen isotope results for the chlorite, however, suggest much higher temperatures than its position in the paragenetic sequence would warrant. These results suggest that the clay formed first as 1:1 layer clays, in this case odinite, which were then transformed to Fe‐chlorite as burial depths and temperatures increased. Reservoirs in the Mahim, Daman and Mahuva Formation sandstones are thus greatly influenced by the diagenesis of authigenic chlorite and locally by the precipitation of carbonate cements. Reservoir quality is good where thick, continuous chlorite rim cements are present and where chlorite pellets are sufficiently indurated for them not to be compacted. Chlorite rim cements have reduced the extent of quartz overgrowth cementation in the sandstones. 相似文献

Rahul Mehrotra maintains a diverse and active role as an architect, urban activist, writer and teacher. His book Bombay: The Cities Within (1995), with Sharada Dwivedi, is a major enquiry into the history and sociology of India's vivacious and contentious urbanism. He finds his city of practice - Mumbai - a mine for quarrying architectural ideations and languages. Unlike most regions in India that may have to adhere to a conformist cultural agenda, Mumbai offers a conceptual freedom in traversing the traditional and contemporary as the city has its particular plurality in the intertwining epochs, attitudes and ‘coming together and moving apart of the past and present’. Multiplicity is thus axiomatic in Mehrotra's interpretation of the city, although this is transferred in his architecture as a dialogical juxtaposition of public and private, exteriority and interiority, natural and industrial materials, and the traditional and contemporary. Interiority, arising both from reasons of climate and urban conditions, is an abiding theme in Mehrotra's work and is articulated through reified courtyards and walls that also retain an intimate conversation with the larger landscape. From residences to large complexes, he uses these elements with great craft and finesse to create dramatic spaces with changing palettes of materials, colours and phenomenally modulated differences between the exterior and interior.‘In our projects, the approach has been to abstract and interpret spatial arrangements as well as building vocabulary,’ he says. ‘The idea is to combine materials, to juxtapose conventional craftsmanship with industrial materials and traditional spatial arrangements with contemporary space organisation. In short, to give expression to the multiple worlds, pluralism and dualities that so vividly characterise the Asian landscape.’ Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Childhood malnutrition remains common in India. We visited families in 40 urban informal settlement areas in Mumbai to document stunting, wasting, and overweight in children under five, and to examine infant and young child feeding (IYCF) in children under 2 years. We administered questions on eight core WHO IYCF indicators and on sugary and savory snack foods, and measured weight and height of children under five. Stunting was seen in 45% of 7450 children, rising from 15% in the first year to 56% in the fifth. About 16% of children were wasted and 4% overweight. 46% of infants were breastfed within the first hour, 63% were described as exclusively breastfed under 6 months, and breastfeeding continued for 12 months in 74%. The indicator for introduction of solids was met for 41% of infants. Only 13% of children satisfied the indicator for minimum dietary diversity, 43% achieved minimum meal frequency, and 5% had a minimally acceptable diet. About 63% of infants had had sugary snacks in the preceding 24 h, rising to 78% in the second year. Fried and salted snack foods had been eaten by 34% of infants and 66% of children under two. Stunting and wasting remain unacceptably common in informal settlements in Mumbai, and IYCF appears problematic, particularly in terms of dietary diversity. The ubiquity of sugary, fried, and salted snack foods is a serious concern: substantial consumption begins in infancy and exceeds that of all other food groups except grains, roots, and tubers. 相似文献

When India was colonised by the British in the 18th and 19th centuries, it was systematically surveyed and delineated in map form for administrative and political purposes. Here, Anuradha Mathur and Dilip da Cunha urge a new, ‘deeper’ reading of the landscape that fully acknowledges the multiple uses and potential initiations of public spaces.

Theorists of Half-Earth Socialism Troy Vettese, Drew Pendergrass and Filip Mesko explain their global societal vision and explore how eco-socialist planning can create a just and sustainable society. They argue that the problem of land scarcity is an opportunity to erode the separation of city and country, while vast swathes of the world could be rewilded. 相似文献

Whilst big data accumulates at exponential rates, its analysis is currently linear. As architect, urban technologist and Academic Director at the Institute for Advanced Architecture of Catalonia (IAAC) in Barcelona Areti Markopoulou points out, at the moment inhabitants of cities are data-captured, yet no circular feedback occurs to make them aware of their actions at the personal and immediate level. She evokes ideas developed by cyberneticians decades ago as the basis for co-created urban design models produced by merging artificial with crowd intelligence. 相似文献

Upgrading of waxy Mumbai High vacuum residue was carried out at four different temperatures, viz. 430, 445, 460, and 475?°C in an autoclavable reactor. The temperature difference between the material at the wall and at the centre of the reactor was found to be as low as 0οC and as high as 10οC depending upon rate of coke formation at different severities. Maximum coke formation (23.31?wt%) was found at 475?°C and for the reaction time of 60?min. Maximum liquid and gas yield was found to be 55.96?wt% and 16.9?wt%, respectively at 475?°C and for the reaction time of 90?min. 相似文献
