The paper overviews the contemporary state of Russia’s heat supply systems and fuel consumption within its centralized part, the structure of heat consumption by economic sectors and types of industrial consumers. As shown, the centralized heat supply systems, providing the major part of country’s economy with low temperature heat, have heat losses and accident rate at a critical level. The state of decentralized heat supply systems of low rise buildings is not covered by national statistics at all. A second paper on the prospects and development of Russia’s heat supply systems will be published in a subsequent issue.  相似文献

Problems in forecasting the demand for Russian-made aircraft and for its aftersale service under an open competitive market are discussed. The applicability of traditional econometric approaches to forecasting the demand for domestic aircraft is analyzed. Prediction methods based on the direct modeling of customer behavior in selecting the park for purchase and its servicing strategy are proposed. Marketing measures aimed at boosting the demand for the Russian aircraft industry’s products are considered.  相似文献

The sub-Saharan Africa challenge programme is designed to address the problems of failures of agricultural markets, inappropriate policies and natural resource degradation, that contribute to the continuing deterioration of livelihoods and food security in the region. It is seeking to do this by redefining the roles of scientists and farmers through collaborative learning processes, addressing questions about the level, timing, type and formof participation, as well as themost effective approaches andmethods to foster them. The research domains of the programme deal with sustainable intensification of smallholder agriculture, the sustainable management of natural resources, the development of efficient markets, and the promotion of enabling policies. One question that was addressed in designing the initiative was deciding where to work so as to maximize the chances of successful testing of this new approach, so that it would lead to significant reductions of rural poverty. A participatory process was put in place to design a framework to accomplish this site selection, and then to apply it in west, east and southern Africa. A mixture of spatial data analysis and expert knowledge on spatial and non-spatial factors was used, and one primary site in each region was identified to form the basis for the next phase of the challenge programme. Several lessons were learnt from the process, including the importance of adapting themethods to actual conditions, the increased utility of targetting when the quantitative and the qualitative are freely combined, and the continued need for baseline spatial and non-spatial data to improve the targeting of research in the future that is designed to alleviate poverty in sub-Saharan Africa.  相似文献

We examine whether mandating banks to issue subordinated debt would enhance market monitoring and control risk taking. To evaluate whether subordinated debt enhances risk monitoring, we extract the credit‐spread curve for each banking firm in our sample and examine whether changes in credit spreads reflect changes in bank risk variables, after controlling for changes in market and liquidity variables. We do not find strong and consistent evidence that they do. To evaluate whether subordinated debt controls risk taking, we examine whether the first issue of subordinated debt changes the risk‐taking behavior of a bank. We find that it does not.  相似文献
