Mobile telephony has become one of the major factors driving the social and economic development of a country. The objective of this article is to identify factors affecting the adoption of mobile telephony in rural India and examine their impact on its adoption. An explanatory empirical methodology with sequential design was used for this purpose, and new factors that affect users’ decisions to adopt mobile telephony in rural India were identified. We extended the technology acceptance model by integrating new factors for a developing nation. This study found that ensuring service transparency and identifying opinion leaders in the local community are key requirements for increasing the speed of adoption in the rural India. The findings of this study will provide insights for service providers and policy makers to develop strategies and policies that will enhance mobile telephony adoption in rural India. 相似文献

Turning the Car Inside Out: Transport, Equity and Environment 总被引:1,自引:0,他引:1
"Turning the car inside out" describes how the environmental damage and social exclusion inflicted by the car can only be seen from outside the car. It explains how car use has reshaped land, time use, social relations and economic patterns. It creates ever more pressures for increased car use, yet inevitably leaves the people temporarily or permanently excluded from cars having to negotiate car distances and times. The worst scenario of car saturation is rejected as untenable both because of the permanent social and environmental impact, but also the self-defeating nature of the quest for mobility. 相似文献

In deciding to adopt lean manufacturing, it is imperative to investigate where and how lean practices are most needed to influence manufacturing and business performance. Such an investigation becomes indispensable when lean thinking is to be considered in a production arrangement different to the conventional, repetitive, high-volume, stable-demand and discrete-manufacturing environment. This study provides explanations of how performance is improved through the adoption of lean practices in process industries. This is a relatively under-researched area compared to the performance effects associated with the introduction and implementation of lean principles in traditional, discrete manufacturing. Based on a survey of Indian process industries, this study attempts to develop an empirical relationship between lean practices and performance improvement through the use of multivariate statistical analysis. The findings have led to the conclusion that lean practices are positively associated with timely deliveries, productivity, first-pass yield, elimination of waste, reduction in inventory, reduction in costs, reduction in defects and improved demand management. However, within a process-industry context, lean practices related to pull production were found to have a marginal impact on performance improvement. A detailed discussion of the findings along with their theoretical and managerial implications is provided in the paper. 相似文献

In this paper, the maximum likelihood estimates of the parameters for the M/Er /1 queueing model are derived when the queue size at each departure point is observed. A numerical example is generated by simulating a finite Markov chain to illustrate the methodology for estimating the parameters with variable Erlang service time distribution. The problem of hypothesis testing and simultaneous Confidence regions of the parameter is also investigated.0 相似文献

In this paper we develop a test based on the empirical distribution function for the alternative representing 'decreasing variance residual life1 property. The test is consistent with asymptotically normal test statistic and is shown to perform well in the Pitman's asymptotic relative efficiency sense. 相似文献

Recently, there have been several reports from different parts of the World on the declining populations of the House Sparrow
(Passer domesticus). In order to assess the population of this species in the National Capital Territory of Delhi-India, this study was conducted
during June– August in 2007. Twenty-eight Fixed-Radius Point Count stations were established in five habitat types viz. High-density
Urban Area, Medium-density Urban Area, Low-density Urban Area, Agriculture Area, and Forested Area, within the study area.
The results show that the House Sparrow is still a dominant species in the agriculture area. However, its density is very
low in the urban areas as compared to the other co-occurring common bird species viz. Rock Pigeon (Columba livia domestica), House Crow (Corvus splendens) and Common Myna (Acridotheres tristis). As, this study was conducted only over one season, the data is not sufficient to provide a clear picture of the population
trend of the House Sparrow. Further studies are therefore required to investigate the relationship of the House Sparrow with
other co-occurring common species, and to analyse the data on the type and quality of greenspaces and their relation with
the House Sparrow in the study area. A long-term monitoring and conservation programme involving local people may be a good
approach for maintaining the population of House Sparrow in the study area. 相似文献

Environmental scanning in U.S. corporations. 总被引:4,自引:0,他引:4
S C Jain 《Long Range Planning》1984,17(2):117-128
Environmental scanning is a new activity among corporations, because of its importance, corporations need to progress by stages to achieve a structured and formal system of scanning, and this takes time. This paper is based on a study examining the evolution and state of environmental scanning among corporations, and finds that the essential difference between scanning at the corporate and at the product/market level is not observed by all companies. Ideally, there should be a close liaison between the two levels so that each may reinforce the scanning effort of the other. 相似文献

Research on interfirm alliances indicates that partner firms’ asymmetry in network centrality increases the likelihood of alliance dissolution because it gives rise to a power imbalance and opportunism in the partnership. We contend that this view of centrality asymmetry does not consider the binding force that network resource complementarity can provide in an alliance, which motivates partners to ally for the long term. We propose that centrality asymmetry can have both divisive and cohesive forces in an alliance, which – when considered together – lead to a prediction that centrality asymmetry has a U‐shaped relationship with alliance dissolution. Moderate levels of asymmetry lead to lower rates of dissolution than high and low levels of asymmetry. The degree of cooperation between partners and the degree of external competition reduce the effects of centrality asymmetry on alliance dissolution because they mitigate power imbalances while encouraging partners to strengthen the alliance to withstand competitive challenges. 相似文献

In recent times, managerial applications of neural networks, especially in the area of financial services, has received considerable attention. In this paper, neural network models are developed for a new application: the pricing of Initial Public Offerings (IPOs). Previous empirical studies provide consistent evidence of considerable inefficiency in the pricing of new issues. Neural network models using publicly available financial data as inputs are developed to price IPOs. The pricing performance and the economic benefits of the neural network models are evaluated. Significant economic gains are documented with neural networks. Several tests to establish generalizability and robustness of the results are conducted. 相似文献

When the development cycle for a product is longer than the development cycle for a core technology that is embedded in it, designers may need to modify the product̂s design to avail of upgrades in this core technology. We model optimal product positioning with regard to technology choice in this setting, using a stochastic dynamic programming framework. Under fairly general assumptions, we find that there are three possible optimal actions: to abandon the project, to maintain the current technology, or to reposition so as to use the best technology currently available. We characterize the optimal positioning sequence in different design environments, discussing throughout the practical implications of our model. Previous research and conventional wisdom suggest early finalization of product specifications if design flexibility is decreasing over time. In contrast, we find that in some design environments, repositioning late in the development cycle can be optimal. 相似文献
