Socio-Technical Systems (STS) theory is rooted in principles that have their origin in action research field projects undertaken by the Tavistock Institute of Human Relations in British coal mines during postwar reconstruction of industry (Trist, 1950). This was a time when mine productivity was failing to increase despite major investments in increased mechanization, while labor turnover and a...
This paper is aimed at making the diffusion of the technological innovation and their role in affecting the agricultural sector in the three-sided (social, economic and environmental), a hand, it can participate to resolve problems of the agricultural sector: the effects of the climatic changes, the farming exodus and the migration and the problems of poverty. The theoretically and empirically ...
This article examines the importance of path dependence effects in impeding the diffusion of high throughput mechanized mining systems in the British coal industry. It demonstrates that the industry had become ‘locked in’ to low throughput underground haulage technology, on account of institutional interrelatedness between Britain’s traditional practice of extensive in-seam mining and its uniqu...
Draft animal power (DAP) has been identified as an environmentally friendly technology that is based on renewable energy and encompasses integration of livestock and crop production systems. Draft animal technology provides farmers with a possibility to cheaply access and use manure from the draft animals and farm power needed to apply renewable practices for land intensification. Compared to m...
By using a histoncally oriented study, the paper sees Information technology (IT) as the successor to three important streams in technologies supporting information-related activities, namely, mechanization, commumcation, and generation and transmission of knowledge. The study aims to show the IT phenomena as something taking place within the context of social and cultural evolution over the pa...
The Ad hoc On-demand Distance Vector (AODV) routing protocol [6] allows the nodes in a Mobile Ad hoc Network (MANET) or a Wireless Mesh Network (WMN) to know where to forward data packets. Such a protocol is ‘loop free’ if it never leads to routing decisions that forward packets in circles. This development mechanises an existing pen-and-paper proof of loop freedom of AODV [4]. The protocol is ...
This paper examines the effect of capitalist control and technological changes in the handloom industry of Varanasi in Uttar Pradesh. The Karl Marx and Harry Braverman’s concept of deskilling is one of the consequences of the capitalistic control and technological changes and it studied theoretically and empirically in the field area. Deskilling is a feature of the labour process theory and it ...
Backgrond and aims: Due to the rapid development of agricultural mechanization operations and the use of tractor as one of the most important agricultural machinery, focus on the health, ergonomic and safety working conditions of the tractor operators is a MUST. Methods: In this research the impact of BMI index and the leg angles of Iranian common tractors drivers on pain threshold reduction...
this study investigated the effects of land size and two leased and private farming systems of machinery on economic efficiency and factors such as total production cost per hectare (ratio of total cost of agricultural inputs and operations to farm size), total income (ratio of product and byproduct value to farm size), yield (ratio of crop production to farm size) and degree of mechanization f...
