Based on the general model of the cost-reducing R＆D, the strategic interactions of output and R＆D investment between labor-managed firms in a duopoly are analyzed. Moreover, the impact of absorptive capacity effects on optimal output in the production stage is discussed. In the R＆D stage, the impacts of absorptive capacity effects on the equilibrium R＆D investment in cooperative and non-cooperative R＆D are analyzed. Finally, the R＆D strategy of labor-managed firms is compared with the behavior of profit-maximizing firms. The results show that equilibrium R＆D investment is always higher than that in the exogenous spillover rate, which is similar to the behavior of the profit-maximizing firms. However, unlike the profit-maximizing firms, the impact of the absorptive capacity that affects the relationship between the optimal output and its own（rival＇ s）R＆D is shown to be dependent upon a return-to-scale of the production.展开更多
Coal Washing Exploration in India dates back to 1900s; though, first coking coal washeries in India were installed after independence.

At present, most of the coking coal washeries are owned by Public Sector Companies; whereas, most of the non-coking coal washeries are owned by Private Sector. Even after six decades of coal washing practices, there has not been significant development in the coal washing intelligentsia. Indian Coal Washing industry is still dependent on imported equipment, which has been designed to treat coal that is significantly different from Indian coal of drift origin. In this paper, authors have ventured into evolution of Indian Coal Washing Industry （with a focus on coking coal washing sector）, its present condition and future prospect for growth. The paper emphasizes need for developing indigenous solutions to industrial challenges and highlights importance of increased coordination among academia-research institutions and coal industry.展开更多

There is a lot of potential locked in spatial data and this potential may be realized by making spatial data readily available for various applications. SD1 （Spatial Data Infrastructures） provides a platform for the data users, producers and so on to generate and share spatial data effectively. Though efforts to develop spatial data infrastructures started worldwide in the late 1970s, SDIs are still perceived by many institutions as new innovation; as such, they have not penetrated to all institutions to bring about effective management and development changes. This paper is reporting on a study conducted to assess SDI Readiness Index for Tanzania. The study aimed at identifying problems undermining SD1 implementation in Tanzania, despite its potential in bringing fast socio-economic development elsewhere in the world. This paper is based on a research based on views from stakeholders of geospatial technology industry in Municipal Councils, Private Companies and Government Departments in Tanzania. Results indicated that Private Companies are more inspired than Government institutions towards implementation of SDIs. And those problems affecting implementation of SDIs are lack of National SDI Policy, lack of awareness and knowledge about SDIs, limited funding to operationalise SDI, lack of institutional leadership to coordinate SDI development activities, lack of political commitment from the Government. It is recommended that delibate efforts be devised to raise awareness of SDI amongst the Tanzanian community.展开更多

Along with the rise of a private economy, private business owners have emerged as a new social stratum, which attracts academic attention domestically and internationally. As for the social origins of the private business owners, some of the private business owners are former cadres and current members of the Chinese Communist Party（CCP）. A question rarely pursued is what effects these ties have on political participation of＂ private business owners. The paper explores this question on the basis of data gathered in a representative survey of private enterprises in 2006. The study shows that the Chinese private business owners have diverse social origins, and their behavior in terms of political participation is also distinct in some ways. When it comes to the patterns of political participation of the private business owners, CCP members and former officials among private business owners indeed have unique characteristics in their access to political resources, but the patterns of political participation vary between these two groups. Furthermore, there are also considerable differences between members of the CCP and democratic parties in China in these respects. These findings cast doubt on the common use of CCP membership and occupational experience as cadre as interchangeable indicators for the ＂political capital＂ of business owners. A more differentiated understanding of the nature of political capital and mechanisms by which it is put to use by private entrepreneurs in China is called for.展开更多
