可持续性发展思想与农用土地开发的生态要求

按照可持续发展思想的基本内涵,土地资源的生产能力和景观环境必须满足人口日益增长和生活水平不断提高的要求,这在客观上要求土地开发利用必须立足于人类持续生存这个核心基础上,保持和提高土地的持续生产能力.本文拟在分析可持续发展思想基本内涵的基础上,对农用土地开发的生态要求进行分析.     

自我思想道德建设研究论纲

自我思想道德建设是个体发展和完善自己主观世界的思想道德活动,而不是传统意义上的思想道德教育方法或原则.作为相对独立的思想道德活动,自我思想道德建设具有自己的运动发展规律,也因之具有独特的研究论域.自我思想道德建设的学科依据、结构、过程和效益等是自我思想道德建设研究论域的基本构成.

激励规制:规制经济学的最新发展

激励规制理论是 2 0世纪 90年代以后在西方兴起的一种新的规制理论 ,是博弈论、信息经济学等微观经济学前沿理论和分析方法被引入产业经济学研究所取得的理论成果。它把规制问题看作是一个委托———代理问题 ,着重研究规制者与被规制者之间存在的信息不对称问题。它使经济学家和政府部门对规制问题的思维方式发生了巨大变化 ,并使政府规制更充分地体现了效率的要求

Risk prediction of hypertension complications based on the intelligent algorithm optimized Bayesian network

Hypertension and its related complications could be a major threat issue for cardiopathy and stroke. Effective prevention and control can decrease the incidence rate of complications in hypertension. Based on the medical data of 3062 patients with cardiovascular and cerebrovascular diseases from 2017 to 2018 in a grade-A tertiary hospital in Shanghai, the study identified the risk factors of hypertension complications by text mining. On this basis, the K2 algorithm based on the improved particle swarm optimization was proposed to optimize the structure of the Bayesian network (BN) by establishing a multi-population cooperative search mechanism. Then the optimized BN was used to analyze and predict the incidence rate of hypertension complications. Results indicate that the major indicators of accuracy, sensitivity, specificity, and AUC have been improved, and the proposed algorithm is superior to the common data mining algorithms such as the back propagation neural network and the decision tree. Through the proposed model and algorithm, the high-risk factors were identified and the occurrence probability of hypertension complications was predicted, which could provide the personalized health management guidance for hypertensive patients to prevent and control hypertension complications.

     

A gold key to initiate a new situation in family planning work]

Because of the popularization of a responsible agricultural production system, the livilihood of peasants has been improving greatly, while the demands and needs of the general public are also increasing at the same time. Still under the influence of the traditional belief of carrying on one's family line and emphasis on having male children, married people prefer to have more childre, and the birth rate is now rising again. In order to solve this new problem, we need to teach the peasants national policies on population, land utilization, and food supply. In order to initiate a new situation in family planning work, we need to control this "gold key" of ideological education and propaganda. The emphasis should be placed on ideological education for cadres at all levels as well as the general public in order that they may understand the Party's strategy. Education on the national strategy should be combined with material interests of the peasants, and reward and punishment in production should also be linked up with that of family planning. Social measures are needed to reduce economic burdens of the peasants, offer better treatment for single-child households, and provide adequate care for old and retired people. Family planning projects should be consolidated and improved. Scientific management, facilities and techniques for birth control, compensation for working personnel in family planning, and other practical problems deserve immediate attention and solution.     

论领导权结构、企业避税与会计信息可靠性的关系

以我国2013—2015年沪深两市A股类上市公司为样本,运用相关性分析和回归分析,以消除应计利润影响后的会计—税收差异作为衡量企业避税指标,用盈余激进度衡量会计信息可靠性,分析企业避税程度与会计信息可靠性的关系,并进行了稳健性检验。结果表明,企业避税程度对会计信息可靠性起负面作用。在此基础上,进一步梳理了领导权结构、企业避税与会计信息可靠性的关系,研究发现,相比两职合一的公司,企业避税程度对会计信息可靠性的负面作用主要体现在两职分离的公司。这对于深入研究企业避税与会计信息可靠性的关系具有一定的借鉴意义,可为完善公司治理机制、提高会计信息可靠性提供一定的思路借鉴和决策参考。     

提升高校学术期刊国际影响力的路径简析

高校学术期刊是衡量一个国家科技创新水平和综合国力的重要标志。在信息技术革新不断加深的今天,提升高校学术期刊国际影响力既是适应时代发展的需要,也是促进国家文化软实力发展的需要。目前,我国高校学术期刊存在着英文期刊数量偏少、中文期刊质量参差不齐、对论文质量把控不严等问题,国际影响力难以有效提升。为了不断提升期刊的国际影响力,我国高校学术期刊需要做到：积极参与国家重点项目,获得国家政策的有效支持;通过外引内联提升国际知名度,努力吸引优秀的国际论文;严把论文质量关,提供高质量高水平的学术论文;与新媒体合作,共享最新科研成果。只有这样,我国高校学术期刊才能不断提高自身学术质量,积极参与国际学术交流,实现期刊国际影响力的有效跃升。     

试论西方人类学仪式研究范式的现代性转换

西方人类学对于"仪式"的研究,从早期的"神话—仪式"学派,到后来的功能主义学派、结构主义学派,再到象征主义学派,将仪式研究从原来视野相对狭窄的宗教神话领域逐步扩展到更为宏阔的社会生活领域。在此过程中,西方人类学仪式研究形成了一套较为完整的人类学仪式研究的知识谱系,完成了西方人类学仪式研究范式的现代性转换。
