The article develops methodological approach to the analysis of groups of interests’ influence on the choice of Russia’s development strategy. It is possible to pass on to the analysis of specific issues of economic policy by forming several sub-groups in every "analytical" group. The article also considers the structure of Russian economy which was formed as a result of transformational crisis’ influence on Soviet economy, and relevant international comparisons. Main alternative ways of transition to innovational development are the renewal of Soviet "triangle economy" (the scenario "Mobilization") and complex institutional changes (the scenario "Modernization").

INTRODUCTION: We compared the physiological responses, psychomotor performances, and hypoxia symptoms between 7000 m and 7500 m (23,000 and 24,600 ft) exposure to develop a safer hypoxia training protocol.METHODS: In altitude chamber, 66 male pilots were exposed to 7000 and 7500 m. Heart rate and arterial oxygen saturation were continuously monitored. Psychomotor performance was assessed using the computational task. The hypoxic symptoms were investigated by a questionnaire.RESULTS: The mean duration time of hypoxia was 323.0 56.5 s at 7000 m and 218.2 63.3 s at 7500 m. The 6-min hypoxia training was completed by 57.6% of the pilots and 6.1% of the pilots at 7000 m and at 7500 m, respectively. There were no significant differences in pilots heart rates and psychomotor performance between the two exposures. The Spo2 response at 7500 m was slightly severer than that at 7000 m. During the 7000 m exposure, pilots experienced almost the same symptoms and similar frequency order as those during the 7500 m exposure.CONCLUSIONS: There were concordant symptoms, psychomotor performance, and very similar physiological responses between 7000 m and 7500 m during hypoxia training. The results indicated that 7000-m hypoxia awareness training might be an alternative to 7500-m hypoxia training with lower DCS risk and longer experience time.Wen D, Tu L, Wang G, Gu Z, Shi W, Liu X.

Vast Range

A number of books on Pakistan's economy have recently been published, but most of them do hot provide the latest statistical data or keep pace with events and development during the 1970's. The book under review, however, has admirably fulfilled the requirements. It covers a vast range of subjects concerning economic development in the country during the recent past The book is divided into nine parts and covers such diverse areas as development, industry, the price situation and the impact of inflation, Pakistan's planning and development effort, trade priorities and balance of payments situation, .taxation* foreign aid, and socio-economic reforms. The analysis is general, broadbased, and historical in perspective and a large amount of data have been put together. To bring out a clearer picture international comparisons are made whereever possible, especially in the last part of the book where the author reiterates on the need for a "New World Economic Order".
