Promoting Fathers' Engagement With Children: Preventive Interventions for Low‐Income Families

Few programs to enhance fathers' engagement with children have been systematically evaluated, especially for low‐income minority populations. In this study, 289 couples from primarily low‐income Mexican American and European American families were randomly assigned to one of three conditions and followed for 18 months: 16‐week groups for fathers, 16‐week groups for couples, or a 1‐time informational meeting. Compared with families in the low‐dose comparison condition, intervention families showed positive effects on fathers' engagement with their children, couple relationship quality, and children's problem behaviors. Participants in couples' groups showed more consistent, longer term positive effects than those in fathers‐only groups. Intervention effects were similar across family structures, income levels, and ethnicities. Implications of the results for current family policy debates are discussed.     

Transfer Pricing in Transition Economies: Evidence from Ukraine

Faced with possibilities and challenges of doing business under different regulatory regimes, transnational corporations have developed a number of transfer mechanisms to take advantage of profit maximization opportunities. Transfer pricing is a transfer mechanism widely used by transnational corporations. Implications of transfer pricing for profitability and the need for transfer pricing regulation are well understood by national governments, which is reflected in the fact that more than 60 governments have introduced some form of transfer pricing controls. Transfer pricing is a challenging issue for transition economies as their transfer pricing regulatory systems are less mature than those of developed countries. The authors have initiated an empirical study on transfer pricing strategies in the Ukrainian market. In addition, the national regulatory regime for transfer pricing was evaluated compared to international best practices. This article is an attempt to draw attention of the research community and Ukrainian policy-makers to transfer pricing issues in Ukraine.      

论电子商务法基本原则

电子商务法学界对电子商务法基本原则的认识仍存在种种分歧和不足.技术中立原则只是民法平等原则的细化,不能成为电子商务法基本原则.在梳理国内现有理论研究并汲取合理成分的基础上,以法律基本原则的原理为基础,从电子商务法解决的核心问题是在非面对面交易环境中,如何确保当事人能够获得商品和价款出发,提出电子商务法基本原则是安全原则.功能等同是判定利用新型信息技术所实施的法律行为有效与否的标准,是安全原则的重要外延和具体化.安全原则要求第三方电子商务平台针对平台内发生的第三方侵权行为负有合理的注意义务.在安全原则指引下,技术中立非绝对,应包含国家安全等例外规则.     

A Note on High-Dimensional Linear Regression With Interactions

The problem of interaction selection in high-dimensional data analysis has recently received much attention. This note aims to address and clarify several fundamental issues in interaction selection for linear regression models, especially when the input dimension p is much larger than the sample size n. We first discuss how to give a formal definition of “importance” for main and interaction effects. Then we focus on two-stage methods, which are computationally attractive for high-dimensional data analysis but thus far have been regarded as heuristic. We revisit the counterexample of Turlach and provide new insight to justify two-stage methods from the theoretical perspective. In the end, we suggest new strategies for interaction selection under the marginality principle and provide some simulation results.     

“90后”大学生思政课教学新思路探析——以宁夏师范学院为例

＂90后＂大学生群体具有坚定的政治信仰、强烈的爱国热情、明确的价值取向;生活态度总体上积极健康,人生目标明确。但是由于各方面原因,这一群体对未来充满了不确定感,紧张、压抑、焦虑的情绪比较严重,如果不能妥善引导和疏通,情况堪忧。高校思政理论课在解决这些问题上发挥着重要作用。因此,思政课应从构建和谐师生关系和创新教学方法等方面,提高其教学实效性。

少数民族高考加分政策的公正性探究

少数民族高考加分政策实施多年,其公正性屡遭质疑,根本原因在于对该政策的根据缺乏深入而系统的认识。事实上,理性约定和平等原则构成其法律基础,循环累积因果论和帕累托最优为其提供经济学上的理论依据,唯有从这两方面厘清该政策的正当性根据,方可消除种种分歧以及在执行和实施过程中的异化和不合理现象。
