高校“两课“教学存在的问题与对策之我见

"两课"是对大学生进行马克思主义理论与思想政治教育的主阵地和主渠道,本文分析了"两课"教学存在的主要问题及原因,对提高"两课"教学实效性的对策进行了探索和思考.     

Lp空间上线性回归方程回归系数的估计

本文讨论了多元线性回归方程参数的L^p估计问题。首先采取消除方程中参数“。的技术，化参数估计为对回归系数的估计，然后进一步将问题转化为一个单目标数学规划模型，利用能自动搜索最优解的电脑软件，十分方便地求出规划模型的最优解。特别对一元回归方程，在消除参数a0后，还可以直接利用普通一元函数求极值的方法，求出回归系数的估计。     

由数学思维过程的辩证性谈数学教学方法的改进

通过对数学思维过程的辩证性分析,阐明了在实际教学过程中应注重学生思维过程,重视从整体看问题应具有的辩证、发展的思维活动方式。尊重学生的思维方式,并且始终在概念的运动、变化、联系、对立统一中去把握概念,对提高学生的学习效率,提高教学质量具有重要意义。     

The impact of relative residence times on the distribution of heavy drinkers in highly distinct environments

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.     

现代经济增长与教育发展的数学模型解析

人力资本是现代社会生产的决定因素.人力资本提高可使社会生产效益指数增长.各个学龄阶段的生均教育投入,都应随着科技知识的指数增长而增长.我国走科技先行、可持续发展的道路,2020年的高等教育毛入学率应达到50％,实现高等教育的普及化,公共教育经费占GDP的比重要在2012年达到4％的基础上继续提高,并在2020年达到4.6％至4.7％,以带动全社会的教育投入占GDP比重提高到7％.
