基于新型核与灰度序列的MGM(1,m,N)模型及其应用

雾霾是空气质量重要评判标准之一，对其进行准确预测能为相关政府部门及时做出正确决策提供理论支持，因此预测雾霾具有实际意义。本文针对区间灰数分布信息已知的序列，构建多个影响因素作用于多个系统行为变量的灰色MGM(1,m,N)模型。首先根据可能度函数计算得到区间灰数的新型核与灰度序列，然后对新型核与灰度序列分别建立MGM(1,m,N)模型以求得模拟值和预测值，最后通过还原得到区间灰数序列的上、下界。为进一步验证该模型的可行性，本文将该模型应用于雾霾相关数据并与基于传统核与灰度序列的MGM(1,m,N)模型进行比较，结果表明本文构建的新模型的模拟预测精度都较传统模型更好。     

论人格心理学课程对大学生心理健康教育的影响

本文利用SCL─90量表,选取大学一、二、三年级共80名选修健康人格教育课程的学生作为实验组,在32学时的课程前后分别测量,同时设置另外36人选修班作为对照组,统计结果分析显示出接受健康人格教育后,学生心理健康水平有所提高,同时本研究对改善今后人格心理研究有启发意义。

The Motherhood Wage Penalty and Its Determinants: A Public–Private Comparison

We investigate whether public and private sector employees bear a different wage penalty for having children. According to our estimates, the total motherhood wage penalty is much larger in the private than in the public sector. Nevertheless, in both sectors, we find no unexplained penalty once we control for potential determinants of the family pay gap, namely, a reduced labour supply of mothers, child‐related career interruptions, less access to management positions, and adjustments in working conditions. Finally, only child‐related career interruptions play a different role in explaining the motherhood wage penalty in each sector.     

Do Interactions between Finance and Labour Market Institutions Affect the Income Distribution?

This article analyses the linkages between financial development, labour market institutions and market income inequality for 18 Organisation for Economic Co‐operation and Development countries over the 1980 to 2012 period. With the help of a dynamic panel data model with an interacted term, one crucial contribution of this article is to analyse the interacted impact of labour market institutions (i.e. union density and employment protection legislation) on the one hand and financial development on the other hand on the income distribution. Our results indicate that changes in the financial/credit and labour market regulation affect the income distribution. Estimates of the marginal effects show that by increasing labour market regulation one also weakens the impact of the flexibilization in the financial/credit market on the increase in income inequality.
