Analysis on the Trend and Factors of Total Factor Productivity of Agricultural Export Enterprises in China

There is an “export productivity paradox” in Chinese enterprises, which has been confirmed in agricultural enterprises. This paper attempts to explain this phenomenon from the perspective of the components of TFP. This paper uses the SFA-Malmquist method to decompose and compare the TFP of China’s agricultural export enterprises based on the data of the state-level leading agricultural enterprises from 2016 to 2017. The conclusions are as follows: firstly, China’s agricultural TFP shows a negative growth trend, and the growth rate of TFP of agricultural export enterprises is less than that of agricultural non-exported enterprises; secondly, the growth rate of TFP of grain and animal husbandry export enterprises is less than that of non-export enterprises; the growth rate of TFP of private agricultural export enterprises is lower than that of non-export enterprises of the same type; the growth rate of TFP of export enterprises in eastern and western regions is lower than that of non-export enterprises; and thirdly, technical progress is an important reason for the change of TFP of China’s agricultural enterprises. However, compared with agricultural non-exported enterprises, improving the technical efficiency of enterprises can more promote the TFP of agricultural export enterprises

Hibernation-Like Behavior Induced by 2-Methyl-2-Thiazoline and Its Organ-Protective Effects and Mechanisms

Hibernation is a prolonged state of low metabolism that animals enter in response to extreme environmental conditions to enhance their survival in harsh environments. Recent studies have shown that non-hibernating species can also be induced to enter a hibernation-like state. 2-methyl-2-thiazoline (2MT), a potent analog of fox odor, can induce fear-related behavior in mice with low body temperature and low metabolism, and has specific organ-protective effects. A systematic understanding of 2MT-induced hibernation and its underlying mechanisms may aid in expanding its applications in medicine and other fields

y Nonprecious Nanoalloys Embedded in N-Enriched Mesoporous Carbons Derived from a Dual-MOF as Highly Active Catalyst towards Oxygen Reduction Reaction

In this work, we reported the synthesis of a novel electro-catalyst composed of Fe and Co bimetallic nanoalloys embedded in N-enriched carbon framework (FeCo@NC) for oxygen reduction reaction. The FeCo@NC was synthesized through pyrolyzing a dual metal-organic framework (MOF) under argon atmosphere. This FeCo@NC electrocatalyst showed remarkable performance towards ORR with a high half-wave potential of 0.827 V versus reversible hydrogen potential (RHE), which was comparable to the state-of-the-art commercial Pt/C catalyst. The enhanced activity could be ascribed to the large specific surface area, the abundant active sites and the synergistic effect of bimetallic alloy
