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。

Early detection of tomato bacterial canker by reflectance indices

Early detection of infected asymptomatic plants could prevent the dissemination of tomatobacterial canker throughout the crop and, thus, reduce associated economic losses. Reflectance spectroscopy has been proposed for the detection of diseases in plants, mainlycaused by foliar fungal pathogens. In contrast, bacterial canker is a vascular disease thatdoes not produce visible foliar symptoms until it is too late to avoid contagion to otherplants. The effects of the disease on the conductivity of the xylem have an impact onthe water content of the leaves;initially, a subtle effect that cannot be assessed with thenaked eye but can be evaluated by reflectance spectroscopy. The objective of this workwas to identify indices, based on the reflectance spectral signature of the plants, for thedetection of tomato plants affected by bacterial canker prior to the appearance of symptoms. To verify that the proposed methodology is applicable to a broad range of tomatogenotypes, two experiments were carried out with different tomato cultivars grown in potsand another on the ground in a greenhouse. Plants were inoculated with the pathogenicbacteria and the reflectance spectrum of the apical leaflet of two leaves per plant wereobtained before symptoms expression;several spectral indices were calculated from thereflectance spectra. Three indices, of the shortwave-infrared zone, allowed the detectionof bacterial canker inoculated plants in a fast and non-destructive way, up to one weekbefore symptoms were visible: Normalized Difference Water Index (NDWI), Simple Ratioof Water Index (SRWI) and Water Index 1 180 (WI1180). Our research demonstrates, forthe first time, the usefulness of spectral indices sensitive to water content for the identifi-cation of diseased plants. These indices arise as a promising tool for the early detection ofvascular plant diseases, that could be integrated into sustainable management plans.

Crop residues: applications of lignocellulosic biomass in the context of a biorefinery

引用

Frontiers in Energy 2022年第2期16卷 224-245页

作者： Maria carolina ANDRADE Caio de Oliveira GORGULHO SILVA Leonora Rios de SOUZA MOREIRA Edivaldo Ximenes FERREIRA FILHO Laboratory of Enzymology Department of Cellular BiologyUniversity of BrasiliaBrasiliaDFBrazil

Interest in lignocellulosic biomass conversion technologies has increased recently because of their potential to reduce the dependency on non-renewable feedstocks. Residues from a variety of crops are the major source of lignocellulose, which is being produced in increasingly large quantities worldwide. The commercial exploitation of crop residues as feedstocks for biorefineries which could be used to produce a variety of goods such as biofuels, biochemicals, bioplastics, and enzymes is an attractive approach not only for adding value to residues but also for providing renewable products required by the expanding bioeconomy market. Moreover, the implementation of biorefineries in different regions has the potential to add value to the specific crop residues produced in the region. In this review, several aspects of crop residue application in biorefineries are discussed, including the role of crop residues in the bioeconomy and circular economy concepts, the main technical aspects of crop residue conversion in biorefineries, the main crop residues generated in different regions of the world and their availability, the potential value-added bioproducts that can be extracted or produced from each crop residue, and the major advantages and challenges associated with crop residue utilization in biorefineries. Despite their potential, most biomass refining technologies are not sufficiently advanced or financially viable. Several technical obstacles, especially with regard to crop residue collection, handling, and pre-treatment, prevent the implementation of biorefineries on a commercial scale. Further research is needed to resolve these scale-up-related challenges. Increased governmental incentives and bioeconomic strategies are expected to boost the biorefinery market and the cost competitiveness of biorefinery products.
