论农村土地资源再分配的经济法调整——以北京市海淀区的农村城市化进程为例

我国农村土地资源再分配的过程受国家公共权力部门的直接调节。目前农村土地资源再分配过程中存在着角色冲突、利益冲突和规范冲突三方面的问题。经济法作为利益资源和权利的再分配书,具有维权性和控权性特点。要实现对农村土地资源再分配过程中的国家调节,并保证调整的结果具有公正性、稳定性和权威性,就亟需借助经济法的作用。     

欠发达地区城镇化进程中的产业支撑

欠发达地区城镇化进程中存在的主要问题是产业支撑虚弱、规模小、功能差、布局分散、资源浪费严重。因此,欠发达地区推动城镇化进程的主要着力点要放在产业化和规模化上,走产业推动和政府推动相结合、缩短战线和重点培育相结合的城镇化道路。     

从法律角度谈中国农村社会养老保险法律制度的构建

中国农村社会养老保险制度已走过了50多年建设历史,经历了从萌芽、发展到整顿规范过程。目前农村社会养老保险正处于探求新的管理制度,解决不规范问题的新时期。从法律视角研究中国农村社会养老保险法制建设中存在的问题以及对中国农村社会养老保险立法工作的必要性、外国立法借鉴及框架设计等问题将对中国农村社会养老保险制度构建具有重要意义。     

农民人权与农村发展的博弈论方法:策略、结局、效用

"三农问题"是国人目前普遍关注热点,农村发展没有质的进步,农民人权保障缺失,农民人权与农村发展双双步入困境。农民人权是农村发展的目的,也是农村发展的手段;农村发展以农民人权为根本出发点和落脚点。基于二者的极大关联性,引入博弈论分析方法是可行的、也是必要的。在博弈模型中,"策略"是对农民人权与农村发展的行为假设。经过纯策略和混合策略的博弈,农民人权与农村发展达成一种利益均衡的契约,这种契约产生的合作共赢的结果,称为"结局"。而对这种结局进行评价称为"效用",表现为以农民人权度量农村发展的评价标准体系。

关于完善农民工养老保险制度的几点对策

我国现有的农民工养老保险制度使农民工不能同城镇职工享有平等的养老保险权益。因此应完善法律法规;加大执法力度;改革不合理的用工制度;建立同农民工相适应的社会养老保险制度;做好统筹方面的工作;完善政策,加强宣传。     

乡村振兴背景下农村留守群体的困境、风险与治理

近几年,中国农村留守群体总量在下降,但庞大的留守群体基数及其背后所彰显的乡村治理价值仍具有研究意义。作为乡村传统主体的留守人口在城乡关系的治理博弈中存在资本动力、人际情感、伦理精神、主体理性和价值认同的风险,并在集体行动中得以呈现。而化解留守群体集体行动的风险在于打造全县域治理共同体、完善社会支持帮扶机制、建立村级生态治理体系、锻造基层党组织组织力、重构乡村现代文化体认。     

Analysis of sensitivity and specificity: precise recognition of neutrophils during regeneration of contused skeletal muscle in rats

In this report, we applied the TissueFAXS 200 digital pathological analysis system to rapidly and accurately identify neutrophils during regeneration of contused skeletal muscle, and to provide information for follow-up studies on neutrophils to estimate wound age. Rat injury model was established, and skeletal muscle samples were obtained from the control group and contusion groups at 1, 1.5, 2, 3, 4, and 6 h, as well as at 1, 3, 5, and 15 d post-injury (n = 5 per group). The expression of nuclei and neutrophils was detected by hematoxylin and eosin (HE) staining and immunohistochemical (IHC) staining. A total of 20 injury site areas of 0.25 mm² (0.5 mm × 0.5 mm) were then randomly selected at all time points. A TissueFAXS 200 digital pathological analysis system was used to identify the positive and negative numbers. Knowledge of five professional medical workers were considered the gold standard to measure the false positive rate (FPR), false negative rate (FNR), sensitivity, specificity, and area under the curve (AUC) of receiver operating characteristic (ROC) curves. As a result, with a staining area of neutrophils from 8 µm² to 15 µm², the FPR was 4.28%–12.14%, the FNR was 12.42%–64.08%, the sensitivity was 35.92%–87.58%, the specificity was 87.86%–95.72%, the Youden index was 0.316–0.754, the accuracy was 82.80%–88.30%, and the AUC was 0.771–0.826. The AUC was largest when the cut-off value of the staining area was 12 µm². Our results show that this software-based method is more accurate than the human eye in evaluating neutrophil infiltration. Based on the sensitivity and specificity, neutrophils can be accurately identified during regeneration of contused skeletal muscle. The TissueFAXS 200 digital pathological analysis system can also be used to optimize conditions for different cell types under various injury conditions to determine the optimal cut-off value of the staining area and provide optimal conditions for further study. Furthermore, it will provide evidence for forensic pathology cases.

解放区文学“大团圆”结局现象论析

解放区文学“大团圆”结局现象的产生 ,与解放区文学所承载的政治宣传使命有关 ,与解放区作家追求文学的大众化、民族化、通俗化思潮相关 ,体现了作家们对“五四”文学所作的某些反拨的自觉。这一文学现象 ,有它存在的历史价值与意义 ,但也不可避免地带来了缺陷与遗憾。
