我国小麦种植面积对价格、成本的反映分析

在协整检验基础上,分析了小麦价格、单位面积成本与种植面积的长期关系。结果表明前期单位面积成本和前期价格与小麦种植面积间存在长期均衡关系,小麦种植面积受前期价格及前期成本的影响,且前期价格对小麦种植面积的影响更大。最后采用脉冲分析及方差分解来分析小麦价格及单位面积成本对种植面积的影响。     

不同补贴方式对中国农村低收入家庭食物安全改善效果比较

2020年后,缓解相对贫困的长效机制将从以往的"扶贫"战略向"防贫"战略转变,亟需构建新型社会救助制度,改善农村低收入家庭的食物安全,推动长效减贫.本文基于2012-2018年中国农业科学院全国农村微观经济数据,估计了农村低收入家庭的卡路里、宏量营养素和4种关键微量营养素的收入弹性,利用所得弹性估值模拟了实现不同营养目...

风险投资声誉、智力资本与企业价值

风险资本与智力资本的有效协同能够实现创业企业知识、资本、管理与创新的完美结合,而拥有高声誉背景的风投在利用其经验和广泛的社会关系帮助企业快速成长方面作用更加突出。本文将创业企业的智力资本划分为人力资本、结构资本、创新资本与社会资本四个组成部分,基于风险投资声誉的视角,探讨风险资本与智力资本的协同关系。结果显示：高声誉风险投资在创业企业人力资本和结构资本两方面的协同效应并不显著,而与创新资本和社会资本两方面的协同效应突出,尤其与社会资本的协同效应能够显著提升创业企业的内在价值。该结论表明高声誉的风险投资机构亟需对目标企业的人力资源、战略规划等方面积极关注,并提供更多的增值服务。     

Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy

Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.

Intermittent control strategy for synchronization of fractional-order neural networks via piecewise Lyapunov function method

In this paper, the synchronization problem of fractional-order neural networks (FNNs) with chaotic dynamics is investigated via the intermittent control strategy. Two types of intermittent control methods, the aperiodic one and the periodic one, are applied to achieve the synchronization of the considered systems. Based on the dynamic characteristics of the intermittent control systems, the piecewise Lyapunov function method is employed to derive the synchronization criteria with less conservatism. The results under the aperiodically intermittent control show more generality than the ones via the periodically intermittent control. For each of the aperiodic and periodic cases, a simple controller design process is presented to show how to design the corresponding intermittent controller. Finally, two numerical examples are provided to demonstrate the effectiveness of the obtained theoretical results.
