基于改进的中位数绝对偏差稳健尺度估计
Robust Scale Estimation Based on the Improved Median Absolute Deviations
 [PDF]


Statistics and Applications (SA) , 2015, DOI: 10.12677/SA.2015.42011
Abstract:
本文基于Smirnor-Shevlyakov在2014年针对位置参数已知为0的稳健尺度估计(即改进的中位数绝对偏差FQn),提出了位置参数未知时的稳健尺度估计(称之为广义中位数绝对偏差GMAD)。数据分析表明:FQn在位置参数未知时不稳健,但GMAD估计在位置参数为0以及未知时均稳健。
Robust scale estimation with unknown location parameters which is called general median absolute deviations (GMAD) was proposed based on a robust scale estimation with location parameters of 0 (improved median absolute deviations FQn) given by Smirnor-Shevlyakov in 2014. The data analysis showed that FQn loses robustness when location parameters are unknown, but GMAD is robust when location parameters are zero or unknown.

Abstract:
约数和函数是一类基本而又重要的数论函数。本文推广了由Bencze提出的两个公开问题的结论,证明了对于任意给定的正整数k和非零整数b,均存在无穷多个正整数n,使得以下三个不等式同时成立:\"\"\"\"\"\",其中为任意正整数n的不同约数之和。
The sum of distinct divisors is a basic and important arithmetical function. In this paper, we extend the conclusions of two open problems proposed by Bencze and prove that, for any given positive integers k and non-zero integers b, there exists infinitely many positive integers n such that the following three inequalities hold simultaneously:\"\" , \"\" and \"\" , where denotes the sum of distinct divisors of n.
内源式发展模式下农村福利院营造与社会工作应对—基于湖北省F、Y两所农村福利院的实证研究

Abstract:
随着人口结构的变迁、家庭功能的弱化以及人们思想观念的改变,在广大农村地区发展公共养老机构已成为必然趋势。本文以湖北省“8 + 1城市圈”中F、Y两所农村福利院为例,采用观察法和访谈法对两所农村福利院的“院民自治”、“院办经济”、“驻地康复”等特色管理和服务进行研究,运用生态视角分析现状,指出当前福利院普遍存在的问题包括:院民有能力改变生存现状而不自知、机构定点服务弊端重重而不自觉、院企联动下问题凸显而不自省等。针对以上问题本文进行了树状模型建构,并提出社会工作应对的三条服务路径:微观的自我认知、中观的社会服务和宏观的制度建设,希望通过一系列的农村福利院营造来改善院民的生活质量,促进农村福利院的内源式发展。
To develop public pension institutions in the vast rural areas has become an inevitable trend with the change of population structure, family function and people’s ideas. This paper takes both F and Y rural welfare homes in “8 + 1 city circle” of Hubei Province as an example, and uses observation and interview methods to research on characteristics of management and service with these two rural welfare homes among people autonomy, welfare economy and home rehabilitation. Then we use the perspective of ecological analysis of the current situation, and point out that the common problems of current welfare homes include: welfare homes and people don’t realize that they have ability to change the survival situation; institutions designated service has many disadvantages; the cooperation of welfare house and enterprises contains many prominent problems while without introspection, etc. In order to solve these problems, this paper builds a tree model, and proposes three paths for the responses of social work service: the micro self-knowledge, medium social services and macro system construction. It is hoped that through a series of construction of rural welfare homes, the living quality of the old people can be improved and the endogenous development model of rural welfare institutions can be promoted.

非物质文化遗产信息化建设的现状及对策——基于对昆曲信息化建设的调研

图书情报工作 , 2011,
Abstract: ?通过对昆曲信息化组织建设、基础设施建设、资源数据库建设、信息化人才建设进行调研,得出昆曲信息化建设虽具有面向知识的资源管理、面向知识管理的资源服务体系、完善政策资金保障等经验,但仍存在标准、合作机制和人才滞后等不足。为此,提出构建交流合作机制、完善政策资金保障、健全技术标准保障、培养综合信息化人才等建议,以推进非物质文化遗产信息化建设,从而更好地保护和传承非物质文化遗产。

保险保障基金的道德危险之殇


- , 2017,
Abstract: 摘要 “保险是现代经济的重要产业和风险管理的基本手段,是社会文明水平、经济发达程度、社会治理能力的重要标志。”①我国保险监督管理委员会自成立以来,在“防范风险方面,遵循‘统筹规划,夯实基础,加强监管’的指导原则,努力构筑以公司内控和治理结构监管为基础,以偿付能力监管为核心,以现场检查为重要手段,以资金运用监管为关键环节,以保险保障基金为屏障的防范保险业风险的‘五道防线’”②。保险保障基金作为“五道防线”的最后一道防线,现行的资金筹集环节、使用环节及追偿环节的缺失易诱发保险公司的道德危险,影响基金的功能发挥,有必要厘清道德危险的成因,寻求对策,降低道德危险对保险保障基金制度的不利影响。
一种新型扇面关联度分析法及在油气田开发定量化类比中的应用
A New Type of Sector Correlation Analysis Method and Its Application in Quantitative Analogy of Gas Oil Field Development
 [PDF]

Advances in Energy and Power Engineering (AEPE) , 2016, DOI: 10.12677/AEPE.2016.44016
Abstract:
本文提出一种用于油气田地质油藏特征及开发指标定量化类比的扇面关联度分析法。该方法首先进行目标油气田地质油藏特征分析和主控因素确定。在此基础上,统计目标油气田和类比油气田的主控参数,建立扇面坐标系,设立主控参数置信度序列,并对扇面坐标系进行调整。然后,在扇面坐标系中绘制目标油气田和各类比油气田的扇面图,并筛选出相似油气田。之后,采用考虑置信度约束条件下的扇面关联度分析法进行目标油气田与多个相似油气田的关联度计算,通过关联度大小对油气田相似程度进行定量化排序,从而最终确定高度相似的油气田。该方法可以从图形和解析两方面定量化精确定位与目标油气田相似度最高的类比油气田,并据此用类比油气田开发策略和实际的开发效果对目标油气田的开发方案制定提供依据,具有较好的实际应用价值。
In this paper, a new type of sector correlation analysis method that can be applied in quantitative analogy of characteristics and development index of gas oil fields is proposed. Firstly, the engineers should analyze the reservoir characteristics and ascertain the dominant control factors, and on this basis, collect the dominant control data of the target gas oil field and analogous gas oil fields, establish the sectoral coordinate, set the dominant control data confidence level sequence and adjust the coordinates correspondingly, then, draw the sectors of the target gas oil field and the analogous fields in the sectoral coordinate and screen out the similar fields. Based on these sector data, the correlation between the fields can be calculated by use of the sector correlation analysis method considering the confidence level sequence. After sorting the value of sector correlation, the similarity degree between the fields and the most similar field can be determined finally. The new type of sector correlation analysis method can be applied in quantitative position of the best analogous gas oil field graphically and analytically, which provides the referential basis to determine the development plan of target field from the development strategies and effect of the analogous fields and has good practical application value.
