延迟退休政策的社会政策分析
The Analysis of Social Policy in Deferred Retirement
 [PDF]


Advances in Social Sciences (ASS) , 2015, DOI: 10.12677/ASS.2015.41005
Abstract:
延迟退休政策是一项重要的社会政策。在当今人口老龄化形势下,影响退休年龄的人口、社会、政治、经济等参数都在变化,而延迟退休政策恰是适应该变化的一种可取路径。本文运用社会政策的分析框架,采用Gilbert和Terrell基于分析视角的框架,对延迟退休政策形成过程进行模拟分析。与延迟退休一词紧密相关的是提前退休,笔者以社会政策中利益博弈的视角看待提前退休问题。从不同的主体出发,以制度视角解读延迟退休年龄政策对各个相关主体的影响。
The social policy of deferred retirement is significant. In today’s aging population tendency, the parameters which affect the age of retirement such as the population, social environment, politics, and economy are all changing. Meanwhile, the implementation of the delay retirement policy could be a desirable path. The author uses the analysis framework of social policy, simulating this process of policy formation based on the Gilbert and Terrell’s framework of Analysis Perspective. The early retirement, always putting on a par with deferred retirement, is analyzed by the game. Finally, the paper shows the influence to the related bodies who will act by the policy of deferred retirement.
我国商业银行系统中准财政活动规模估算及政策建议

中央财经大学学报 , 2012,
Abstract: ?在我国金融系统中存在的大量的准财政活动,对于研究公共财政资源的规模问题构成一定的干扰。目前在学术界对金融系统中中央银行和政策性银行准财政活动研究成果较多,但对于商业银行系统中准财政活动研究非常少。主要原因是商业银行系统中准财政活动在发达的市场经济国家较为少见,只有在利率市场化尚未完全实现,商业银行的日常经营仍受中央或地方政府直接或间接干预的情况下,才会大量出现。本文将重点放在对金融系统中的核心——商业银行子系统中准财政活动的分析,通过对近三年商业银行系统中准财政活动规模的分类估算,对其产生原因进行分析,并提出相应的政策建议。
典型陕北长焰煤热解行为及其动力学实验研究

大连理工大学学报 , 2013, DOI: 10.7511/dllgxb201303004
Abstract: 利用热重分析(TGA)技术研究了升温速率对典型陕北长焰煤热解行为的影响,并用总包反应模型和分布活化能模型(DAEM)对其进行了动力学分析,比较了两种模型对3种典型陕北长焰煤热解的适应性.TGA结果表明典型陕北长焰煤热解分为3个阶段,增加升温速率使活泼热分解阶段和二次脱气阶段最大失重峰对应的热解温度向高温区移动,热解转化率降低.动力学分析表明:总包反应模型由于其假设只能得到某一温度范围内活化能和指前因子的平均值,且数值较低.DAEM可得到热解活化能的分布区间32~446kJ·mol-1,3种长焰煤热解表现出不同的活化能分布趋势.DAEM可较好描述黄土庙(HTM)煤样热解的全过程,活化能主要分布于181~425kJ·mol-1,出现两个峰值,对应的活化能分别为419kJ·mol-1和425kJ·mol-1.DAEM可描述府谷(FG)和张明沟(ZMG)煤样失重率在10%~55%的热解行为,活化能和频率因子随转化率的增加而升高.DAEM能描述非等温热解从低温到高温的过程,真实反映不同煤样热解过程的差异性、复杂性、连续性.

人地关系研究新模式与地理虚拟创新环境

地球信息科学学报 , 2004,
Abstract: 从地球系统科学和地理科学研究内容与研究手段的角度出发,探讨数字地球对人地关系研究的影响,在新技术框架下,地球系统科学所研究的新人地关系,成为实现可计算的人地关系的现代地理学发展关键阶段所必需的理论与技术依托。研究认为在数字地球实验室框架下,可以实现为地理科学的原始性创新提供虚拟创新环境。地理科学虚拟创新环境以不同空间、时间分辨率的数据为基础,或以物质和能量的多种分辨率的有关资源、环境、社会、经济和人口等海量数据或信息进行数据融合后产生的数据,按照一定的地理坐标,从里层到外层,从岩石圈到生物圈、大气圈,从局部到整体,从区域到全球进行整合、融合及多维(如4维)动态模拟,从而为解决地理科学这个复杂巨系统现状描述、历史反演、未来预测研究提供知识创新的平台、技术开发与理论研究的实验基地。

风险资本是否提升了中国企业的技术创新积极性? ――基于资本价格扭曲背景下的“双重替代效应”
Has the Venture Capital Improved Chinese Enterprises′ Technology Innovation Enthusiasm? ―A study of the "double substitution effects" based on the capital price distortion


- , 2017, DOI: 10.15896/j.xjtuskxb.201702003
Abstract: 为了考察资本价格扭曲下风险资本对中国企业技术创新积极性的现实影响,对2009-2015年间有风险资本参与的创业板上市公司进行面板数据回归。结果发现:风险资本对中国企业的技术创新活动确实存在正向激励作用,且进入时机越早,对企业创新的激励作用越大;然而,目前中国资本市场上存在的资本价格负向扭曲以及风险投资行业本身存在的进入时机过晚等问题,对风险资本的创新激励功能产生了“双重替代效应”,从而不利于企业技术创新积极性的提升。为此,今后,应当通过加强利率市场化改革、完善风险投资政策等措施来充分发挥风险资本的创新激励作用。
This paper uses the data of Chinese companies listed on the GEM which have been participated by venture capital from 2009 to 2015, by the analysis of panel data regression, to explore the innovation incentive effects on China′s venture capital. The results show that venture capital has played a positive role to Chinese enterprises′ technology innovation activities, and the earlier it enters, the greater the incentives are. But the negative distortion of capital price and the entering later problem have impeded the incentive function of venture capital through the "double substitution effects". So, this paper suggests that the government should give full play to the innovation incentive of venture capital by strengthening the market-based reform of interest rates and improving the risk investment policies

Abstract:
面对进化历程中疾病提出的生存威胁,人类进化出了行为免疫系统以抵御疾病的传播。本文首先对行为免疫系统的基本功能特征进行了总结,在此基础上,进一步阐述了行为免疫系统对社会行为的影响。已有的研究显示,行为免疫系统主要从两个层面——回避疾病威胁和服从社会规范对社会行为产生影响,分别表现为:1) 行为免疫系统对异常身体特征偏见态度的影响;2) 对群际偏差的影响;3) 对从众行为的影响;以及4) 对集体主义文化的影响。最后,本文对行为免疫系统对社会行为影响研究的未来发展方向进行了展望。未来的研究应当更多地考虑到不同文化背景下行为免疫系统对社会行为的影响,以及进一步细分行为免疫系统在情绪上产生的效应。
Facing the disease threat in the evolution history, humans evolved the behavior immune system to resist the spread of disease. On the basis of summarizing the basic function features of behavior immune system, the current article further elaborates the impacts the behavior immune system has on social behavior, which have been documented in existing literature from perspectives of disease threat avoidance and social norms conformity. The influence of behavior immune system on social behavior are respectively: 1) on the prejudice to abnormal physical features; 2) on group bias; 3) on conformity behavior and 4) on collectivism. The last part of the current article is the prospect of future developing of researches on the relationship between behavior immune system and social behavior. The future researches should take various cultural contexts into account and pay more attention to subdivide the emotion effect caused by behavior immune system.
群际威胁及其对群体偏见的影响
Intergroup Threat and the Effect to Group Prejudice
 [PDF]

Advances in Psychology (AP) , 2015, DOI: 10.12677/AP.2015.511079
Abstract:
群际威胁是指在社会群体生活中,某一群体拥有的资源、观念及价值观等特征对另一群体的生存安全与发展福祉等带来的威胁。群际威胁的存在使得个体容易对可能给内群体及其成员带来威胁的外群体产生消极的态度,即群体偏见。这是一种适应性的心理机制。研究者将群际威胁分为三大类,即现实威胁、文化威胁及认同威胁。目前的文献集中于研究现实威胁与群体偏见的关系,并试图从单一的模型发展为从整合角度提出的整合的群际威胁模型。未来的研究应加大对群际威胁模型的探讨;在研究方法上,应采用更多的实验研究;研究内容方面,目前研究者主要考察个体对外群体的态度,对内群体态度方面还需要进行更多的丰富与补充。
Intergroup threat refers to the threat of resources, ideas, values and other characteristics that a group owns to the other group’s survival, security, development and happiness in social life. The presence of intergroup threat makes it easier for individuals to have a negative attitude to the out-group who may bring threat to themselves as well as their in-group, and it is called group prejudice. This is an adaptive psychological mechanism. Intergroup threat is divided into three categories: realistic threat, cultural threat and identity threat. The current literature focuses on the study of the relationship between realistic threat and group prejudice. Research on the model of intergroup threat has progressed from a single model to an integrated intergroup threat model proposed from a perspective of integration. The future research should increase the discussion on the model of intergroup threat. About research methods, more experimental studies should be used. Currently, researchers mainly investigate individuals’ attitude to out-group, but the attitude to their own group should get more attention too.
定向井随钻监测计算
,
天然气工业 , 2005,
Abstract: ?钻井中,需要对将要钻达的下部地层深度进行预测,特别是在定向井的钻探过程中显得尤为重要。目前的井斜角、方位能不能满足钻达目标靶区的地质需要,或者地下地质情况(地层厚度、倾向、倾角)发生变化后钻井措施的相应改变,以及需要调整改变的钻井参数怎样确定等,都需要经过严密的计算和分析。文章对钻井轨迹和地质情况进行了分析,从地质层位的小层入手,对构造的走向、倾向、倾角,地层的真厚、铅直厚度,钻井的方位、井斜角、实钻地层厚度等参数进行了分析,在三维空间的基础上,建立了实钻的数学模型,明确了各参数间的关系。推导出的公式适用于包括定向井在内的钻井参数计算,可以在地层钻厚预测、深度对比,钻达目标靶区的水平位移及井斜角、方位角的调整,穿越储层厚度的计算及钻井参数的调整,目标靶区是否在气水界面以内及钻达预想海拔高程的钻井参数调整等多个方面进行运用,这对下步钻井达到地质目的具有重要的指导作用。
