Since 1986, Cuba has been engaged in a national effort to redirect its polity and economy; this effort, spearheaded by President Castro, is generally known as the “rectification” campaign. Although occurring at roughly the same time as reforms in the Soviet Union and Eastern Europe, the Cuban process—which emphasizes dismantling market-oriented mechanisms and enhancing economic centralization—differs radically from the others. An impressionistic assessment of the economic effects of rectification after its first three years (focusing on the behavior of macroeconomic indicators and of the construction sector) suggests that rectification has not turned the Cuban economy around. Moreover, it is questionable that rectification could do so in the medium term, considering the reforms that are taking place in Cuba's main trading partners, the Soviet Union and Eastern Europe. Jorge F. Pérez-López is an international economist with the Bureau of International Labor Affairs, U.S. Department of Labor. This article presents only his personal views. He has written on different aspects of the Cuban economy, including economic growth, the sugar industry, international trade and energy balances. His book,Measuring Cuban Economic Performance, was published by the University of Texas Press in 1987.  相似文献

This paper presents a product development methodology for use with indigenous rural workers. It is based on the revival of cultural and social values, with a focus on the conservation of natural resources. Illustrated by the case of Mixtec craftswomen in Mexico, this paper shows how poor groups can improve their living conditions through innovation and the diversification of their products. The process combines techniques of product development based on marketing, with a participatory focus and continuous improvement, in order to develop a unique and high‐quality product that can be more successfully marketed. The craftswomen are now able to plan their production and can evaluate and commercialise their products.  相似文献

This case is about the finding of a body of an unidentified male of approximately 70 years of age who was hit by a train. During the carrying out of the corresponding autopsy and after the radiological tests for posterior odontological identification, a foreign body of a cylindrical-cone shape, identical to that of a bullet, was found lodged between the first and second cervical vertebrae. During dissection of the neck, a bullet was found. When the ballistic test was carried out, it was ascertained that the bullet was from a cartridge of 7.92 by 57-mm Mauser caliber, manufactured in Spain in 1936. This ammunition corresponds to that used during the Civil War in Spain (1936-1939). After the identification of the body, it was proved that the bullet was the result of a war wound. However, the victim had been unaware of the existence of the bullet, which had remained in his body for 50 years.  相似文献
