Receive or give? Contemporary views among middle-aged and older Chinese adults on filial piety and well-being in Hong Kong

This qualitative study aimed to examine the contemporary interpretation of filial piety by middle-aged and older Chinese adults in Hong Kong, and to explore its relationship with well-being in later life through focus groups. Data analysis revealed that all participants subscribed to the traditional value of filial piety, but had willingly reduced their filial expectations of their younger generation. Importantly, well-being in later life was found to be affected by both the younger generation’s filial commitments and older parents’ continued support of their younger generation so that the latter could lead a better life.     

基于内生增长理论与GVAR模型的能源消费控制目标下经济增长与碳减排研究

本文通过引入使用可替代能源生产的中间产品,构建能源约束和碳排放约束下的内生经济增长模型,并运用全局向量自回归(GVAR)模型,实证分析了具有空间关联性的中国各省(区市)能源消费控制对经济增长和碳排放的动态影响。研究结果表明:在不影响经济增长且受碳排放约束条件下完成能源消费总量考核的目标,可以通过研发可再生能源、提高碳排放清洁技术水平、增加碳基能源的边际产出等实现;能源消费总量的考核目标对能源消费强依赖地区约束性较强,对其余地区的约束力较弱,其余地区可节能潜力较强;能源结构逆向调整的存在使得控制能源消费总量对少部分省(区市)无法达到减排效果。进一步地,本文实证分析了目前节能减排实施过程中可能存在的问题:科技进步对能源结构顺向调整效果不显著、可再生新能源的研究效率低下,技术进步对碳排放清洁方面无显著效果;依靠传统能源价格的调整虽能有效减排却会抑制经济增长。     

Creating catalogues of two-level nonregular fractional factorial designs based on the criteria of generalized aberration

We consider the problem of constructing good two-level nonregular fractional factorial designs. The criteria of minimum G and G₂ aberration are used to rank designs. A general design structure is utilized to provide a solution to this practical, yet challenging, problem. With the help of this design structure, we develop an efficient algorithm for obtaining a collection of good designs based on the aforementioned two criteria. Finally, we present some results for designs of 32 and 40 runs obtained from applying this algorithmic approach.     

Regularization and variable selection for infinite variance autoregressive models

Autoregressive models with infinite variance are of great importance in modeling heavy-tailed time series and have been well studied. In this paper, we propose a penalized method to conduct model selection for autoregressive models with innovations having Pareto-like distributions with index α∈(0,2)$\alpha \in (\mathrm{0,2})$. By combining the least absolute deviation loss function and the adaptive lasso penalty, the proposed method is able to consistently identify the true model and at the same time produce efficient estimators with a convergence rate of n^−1/α$n^{-1/\alpha }$. In addition, our approach provides a unified way to conduct variable selection for autoregressive models with finite or infinite variance. A simulation study and a real data analysis are conducted to illustrate the effectiveness of our method.     

SAM平衡的SG-RAS与SG-CE方法

随机cross entropy(Robinson et al.,2001)方法是目前用于平衡社会核算矩阵的最主流方法,本文综合其与GRAS(Lenzen et al.,2007)方法的思想,扩展提出了SG-CE(stochastic generalized CE)与SG-RAS方法,避免了原始CE方法在平衡SAM时需要对负值元素进行预处理的步骤,试图改进由此引致的缺陷并提高平衡SAM质量。在此基础上,本文运用SG-RAS、SG-CE、CE以及国内常用的余量法对中国2007年SAM进行了平衡,实证结果的对比表明:在平衡系数SAM时,SG-RAS优势非常明显;而平衡流量SAM时,除SG-RAS之外,余量法也具较好表现;但无论是平衡系数还是流量SAM,SG-CE的效果只能说差强人意,原始CE方法更差。     

暂时性差异相关问题研究

在会计核算中,暂时性差异分为应纳税暂时性差异和可抵扣暂时性差异,会计处理时,应纳税暂时性差异计入递延所得税负债。而可抵扣暂时性差异计入递延所得税资产科目。在企业会计准则中,企业未来期间无法取得足够的应纳税所得额时．对递延所得税计提减值,笔者对此有点质疑。

我国航空运输LTO阶段和巡航阶段排放量测算与预测

利用国际民航组织的发动机排放数据库和我国航空运输的生产数据,测算2011—2016年我国航空运输在LTO阶段和巡航阶段各种污染物的排放量。同时,针对典型机型、典型机场和典型航线进行相关污染物排放量的测算。研究方法和研究结论对于测算和治理我国航空运输排放产生的环境外部成本具有重要意义。     

制度、法官与难办案件——从唐慧上访案等切入

在当下中国司法语境中,司法信任危机越来越凸显.从宏观上来看,是因为改革开放的深入,外来权利观念的冲击,同时社会结构变革加速,社会同质性降低.但是在这样一个社会中,我国的一些诉求机制却存在不尽合理的地方,这主要表现在司法诉求机制与行政诉求机制并存,使得机构设置冗杂、行政权司法化,使得本该由司法机构来定纷止争的难办案件,更多的却由行政机关来审判或者干涉.这不仅导致了审判效率的低下和权力与其行使主体的不对称,而且促使行政权在逐渐侵蚀司法权.这固然是制度本身的结果,但是最为重要的是法官在审判难办案件时处理不当的结果.以实用主义的审判思维为导向,重塑司法权威,进而促使行政诉求机制慢慢走向消亡.
