Degradation processes affect a vast area of arid and semi-arid lands around the world and damage the environment and people′s health. Degradation processes are driven by human productive activities that cause direct and indirect effects on natural resources, such as species extinction at regional scale, reduction and elimination of vegetation cover, soil erosion, etc. In this context, ecological rehabilitation is an important tool to recover key aspects of the degraded ecosystem. Rehabilitation trials rely on the use of native plant species with characteristics that allow them to obtain high survival and growth rates. The aim of this work was to assess the survival and growth of native woody species in degraded areas of northeastern Patagonia and relate them to plant functional traits and environmental variables. We observed high early and late survival rates, and growth rates in Prosopis flexuosa DC. var. depressa F.A. Roig and Schinus johnstonii F.A. Barkley, and low values in Condalia microphylla Cav. and Geoffroea decorticans(Gillies ex Hook. & Arn.) Burkart. Early survival rates were positively associated with specific leaf area(SLA) and precipitation, but negatively associated with wood density, the maximum mean temperature of the warmest month and the minimum mean temperature of the coldest month. Late survival rates were positively associated with SLA and soil organic matter, but negatively associated with plant height and precipitation. The temperature had a positive effect on late survival rates once the plants overcame the critical period of the first summer after they were transplanted to the field. Prosopis flexuosa and S. johnstonii were the most successful species in our study. This could be due to their functional traits that allow these species to acclimatize to the local environment. Further research should focus on C. microphylla and G. decorticans to determine how they relate to productive conditions, acclimation to environmental stress, auto-eco

本文回顾了琼·罗宾逊于1942年转向马克思经济学的动因,并考察了她如何尝试将马克思的经济学见解融入自己后续的研究工作中。同时,文章也评论了罗宾逊同时代的学者对罗宾逊与马克思思想交汇的看法。在20世纪30年代末,罗宾逊寻求发展一个更切合实际的利润率和收入分配理论,旨在阐明约翰·梅纳德·凯恩斯的充分就业概念和技术进步的本质,并在凯恩斯主义框架内构建一个长期理论体系。正是在这个过程中,罗宾逊开始尝试将正统经济学与马克思经济学相结合,并在1942年出版了其重要著作《论马克思主义经济学》。这本书奠定了罗宾逊对正统经济学长期挑战的基础,依靠马克思经济学的洞见摆脱了阿尔弗雷德·马歇尔的正统思想,并推动了剥削理论的发展。
