论情感育人在大学生思想政治教育中的特殊效应

情感育人的特殊效应就是通过情感的交流,对教育对象实施"情感激发",使教育对象完成思想的转化和升华.在情感育人的过程中,教育者应从学生的实际需要出发,捕捉学生的思想闪光点,通过网络技术,运用情感育人,发挥情感育人的最大效应,获得思想政治教育的最佳效果.     

ln(n!)的数量级

在许多运用比如概率记中,需要知道n!的数量级.本文推出ln(n!)与nlnn具有相同的数量级.     

20世纪初上海城市客运业与官商互动模式的嬗变

上海城市区域不断扩大,导致城市人口形成空间活动固定模式,产生了现代公共交通方式。华界现代公共交通基本由民间社会集资兴办,民族交通企业创办了华界地区现代公共交通。在民间资本式微的情况下,上海市政府公用局尝试性地运用政府的独特优势,整合相关社会资源,积极介入区域公共交通的建设与发展之中,取得了初步成效。同时公用局坚持华界公共交通“以公营为宜”的主张,加强对商办交通企业监管,引起了监管方式的争执。     

Regularization and variable selection via the elastic net

Summary.  We propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the lasso, while enjoying a similar sparsity of representation. In addition, the elastic net encourages a grouping effect, where strongly correlated predictors tend to be in or out of the model together. The elastic net is particularly useful when the number of predictors ( p ) is much bigger than the number of observations ( n ). By contrast, the lasso is not a very satisfactory variable selection method in the p ≫ n case. An algorithm called LARS-EN is proposed for computing elastic net regularization paths efficiently, much like algorithm LARS does for the lasso.

Applications of schur theory to reliability inference for k of n systems

The results of Hoeffding (1956), Pledger and Proschan (1971), Gleser (1975) and Boland and Proschan (1983) are used to obtain Buehler (1957) 1-α lower confidence limits for the reliability of k of n systems of independent components when the subsystem data have equal sample sizes and the observed failures satisfy certain conditions. To the best of our knowledge, for k ≠ 1 or n, this is the first time the exact optimal lower confidence limits for system reliability have been given. The observed failure vectors are a generalization of key test results for k of n systems, k ≠ n (Soms (1984) and Winterbottom (1974)). Two examples applying the above theory are also given.     

Smoothing Splines with Boundary Correction

Regular smoothing splines are known to have a type of boundary bias problem that can reduce their estimation efficiency. In this paper, a boundary corrected smoothing spline with general order is designed in a way that the risk will decay at an optimal rate. An O(n) algorithm is also developed to compute the resultant estimator efficiently.     

Pension scheme fees and charge ratios in 44 countries: A comparative study

Based on data received from pension supervisory authorities, the article reviews 85 different pension schemes in 44 jurisdictions by looking at fees and charges as well as their legal ceilings and their development since 2014. A key finding is the observed decrease in fees and caps. The article presents jurisdictions according to clusters, i.e. by groups of countries with identical or very similar items already covered by pension fees, and analyses the extent to which various cost and fee elements are covered by fees charged to members. Finally, we calculate charge ratios for each cluster to quantify the impact of fees and charges on pension savings. Occupational defined contribution pension schemes and personal plans linked to employment tend to be much more cost effective than personal schemes that have no direct employment link.     

古兰学与经注学关系研究

古兰学(‘Ulūmal-qur’ān)是研究《古兰经》的基础学科,也是伊斯兰文化体系的传统学科。尽管古兰学是一门独立学科,但它因以《古兰经》为研究对象而具有多学科交叉特点,并由此产生了若干分支学科,经注学(‘ilmal-tafsir)则是其中最重要的主干学科。古兰学与经注学在学科原理和认知经文层面的共性关系,既有助于人们了解和理解《古兰经》的文体经义,也为伊斯兰文化发展提供不可或缺的思想资源。     

Reforming against all odds: Multi‐pillar pension systems in the Czech Republic and Romania

Attempts to replace pay‐as‐you‐go pension schemes with private funded systems came to a halt in Central and Eastern Europe after 2005. However, more recently, the region has witnessed two belated reformers: the Czech Republic and Romania. Both countries decided to partially privatize pensions despite the rising tide of evidence concerning the challenges associated with the policy. We argue that while part of the domestic political elite remained supportive of private funded pensions, the difficulties experienced by earlier reformers and reduced support from International Financial Institutions led to the adoption of small funded pension pillars. Such cautious attempts at privatization might become more common in the future as large reforms have proven politically unsustainable.
