Extensions of Samuelson's Inequality

In this note we obtain upper and lower bounds for the kth largest number in a set of real numbers in terms of their mean and standard deviation. For each inequality necessary and sufficient conditions for equality are given.     

Correlation,Regression Lines,and Moments of Inertia

The R language, a freely available environment for statistical computing and graphics is widely used in many fields. This “expert-friendly” system has a powerful command language and programming environment, combined with an active user community. We discuss how R is ideal as a platform to support experimentation in mathematical statistics, both at the undergraduate and graduate levels. Using a series of case studies and activities, we describe how R can be used in a mathematical statistics course as a toolbox for experimentation. Examples include the calculation of a running average, maximization of a nonlinear function, resampling of a statistic, simple Bayesian modeling, sampling from multivariate normal, and estimation of power. These activities, often requiring only a few dozen lines of code, offer students the opportunity to explore statistical concepts and experiment. In addition, they provide an introduction to the framework and idioms available in this rich environment.     

基于家庭收入的保障性住房标准研究

 保障性住房是关系国计民生的重大问题,为使保障性住房充分发挥作用,其准入标准的确定尤为重要。目前我国保障性住房准入标准大都以人均收入作为参考指标,本文旨在测算并确立以家庭收入为参考指标的保障性住房准入标准。由于厦门市保障性住房在全国具有示范效应,故以厦门为例考察基于家庭收入的保障性住房准入标准。根据抽样调查的分组数据界定“中低收入组”,通过正态分布与均匀分布的转换,利用格点映射法,找出覆盖面为40%的收入上限值,即为保障性住房的准入标准。基于此标准,结合“按年人均收入限值”这一指标,将家庭组别按人口细分,划分出针对不同家庭规模的参考准入标准。     

SA8000认证对我国的影响及其对策

介绍了SA80 0 0认证标准及其对我国的影响,并提出了具体的应对策略。作者认为我国作为劳动密集型产品的出口大国,将受到社会责任运动的重大影响,但它既非天使也非魔鬼,政府和企业必须严肃而辩证的看待它。同时,作者提出要认清实施社会责任标准和SA80 0 0认证的阶段性,结合我国的发展阶段,积极主动的、有取舍的接受它。     

思想政治教育实效测评标准:一个亟待研究的问题

思想政治教育实效测评标准建构是思想政治教育学科的现实而紧迫的前沿性课题。思想政治教育实践活动呼唤科学有效的实效测评标准;思想政治教育理论建设需要加强实效测评标准的研究;思想政治教育实效测评标准的建构能够积极推进思想政治教育的前沿发展。     

社会责任管理体系SA8000视角下的我国劳工权益保护

随着社会责任管理体系SA8000在全球范围的逐步推广,它对我国的对外贸易产生越来越广泛的影响,成为发达国家用来限制发展中国家劳动密集型产品出口的有力工具。SA8000充分体现人的生命价值和人力资源的重要性。实施SA8000正是体现了对员工的社会责任意识,为他们创造良好的劳动环境和激励措施,可以充分发挥他们的主动性和创造性。     

基于SA8000完善中小企业员工福利的新途径——论企业社会工作的介入

随着市场经济的发展,企业间人才的竞争日益加剧,员工福利已悄然成为企业吸引、挽留人才的重要砝码,SA8000的出现又进一步强化了企业对员工福利管理的要求。构成我国经济发展基石的中小企业在员工福利管理方面存在问题,试图在SA8000的视野下运用企业社工的介入对我国中小企业员工福利管理的完善进行一番尝试。     

批发和零售业在ISIC4.0和NACE2.0中的分类比较研究及启示

 ISIC是世界上对经济活动进行分类的最成熟、最权威、最有影响力的国际标准,而NACE派生于国际标准产业分类体系,是派生型产业分类体系的典型代表。深入了解最新版ISIC4.0和NACE2.0的批发和零售业分类的差别,对我国国民经济行业分类的批发和零售业依据ISIC4.0进行修改和调整具有重要的借鉴价值,同时对正确收集、处理和测算批发和零售业的经济指标以及国际间数据比较至关重要。故本文对上述两大产业分类体系进行比较研究,揭示批发和零售业在上述产业体系中的差别,提出我国国民经济行业分类体系的批发和零售业分类的改进建议。     

It's More Than an M‐shape: The Political Economy of Female Non‐Standard Workers in the Republic of Korea

This study examines the re‐entrance of female workers into the Korean labor market. We highlight that women in their 40s have the highest rate of employment among all female workers and that a large proportion of these women are entering into non‐standard employment. In approaching this question, we examine the political economy of this phenomenon by first discussing the demand side of the Korean labor market using the gendering of the varieties of capitalism argument and then the supply side with the work–life balance argument. When examining re‐entrance into the labor market, women with general skills with lower education and higher education both found it more feasible to re‐enter the labor market as non‐standard workers. While work–life balance is a prominent reason for women's choice of opting out of the labor market, work–life balance choice mattered less for women re‐entering the labor market as non‐standard workers in their 40s and 50s but instead firmly based skill formation mattered more. In addition, the retail service industry is suggested to absorb a large number of female workers with lower skill levels who would have had difficulties in re‐entering other male‐oriented companies.     

关于建立标准人（Standard Person简写SP）体系的假设

人作为生物,也作为社会成员,他们具有不同的个体特征,但同时又具有共同之处,这些共同之处我们可以从人的身体素质、思想素质和科学文化素质等进行比较。标准人体系假设就是试图从这几个重要因素及其子因素对人的影响中确定一个标准人所拥有的条件,以及各因素对标准人的影响权重,也就是对人的条件进行量化,并提出本假设的目的,解决的问题和作者希望通过本假设对社会学、人口学、人类学、人口社会学等学科的研究提供一种新的视角。
