从造字到造形：汉字形体结构与书法艺术

汉字作为一种书写形体，笔画组合的丰富多样和间架结构的灵活多变，而使其“字形”成为复杂的美学构成，“书写”成为“书法”，并完成从造字到造形的转变。书法是汉字书写艺术，书法艺术深藏于汉字独特的形体结构之中。三位一体的整体架构、二维方块结体、平衡对称等汉字在形体构造上的诗性特征，既是人们对文字形体的一种审美预期，也是书法学家在书法创作时努力追求的美感。     

Sociolinguistics and modes of social class signalling: African perspectives

The paper evaluates spatial, behavioural, and material signalling of social class in African contexts, focusing on Kenya and Zambia. In particular, it draws on notions of mode of class signalling and intersectionality and a vignette of an interaction between urban‐based Western educated development agents and local participants in rural Kenya to illustrate how social class is implicated in interactions. The paper shows how significant features of class and dimensions of social inequality may be perceived intersectionally so that positionalities in class structures are negotiated in contexts of interaction, thus illustrating how structural conditions of class may be challenged and questioned. The paper concludes that sociolinguistics needs to identify the various ways in which the marginalized challenge social structures of inequality. Otherwise there is a risk that sociolinguistics will work to validate inequalities as permanent and fixed, and victims of unequal treatment as permanently condemned and never able to rise against oppressive social structures that tyrannize them.     

Regulation and the future of work: The employment relationship as an innovation facilitator

Digital transformation and the reorganization of the firm have given rise to new forms of work that diverge significantly from the standard employment relationship. Advocates of digital disruption suggest that the existing legal framework cannot accommodate “innovative” working templates and business models. This article, however, argues that labour regulation can continue to facilitate innovation, presenting the employment relationship as a flexible instrument, and standard forms of employment as the means of achieving efficiencies and cost advantages. First, they allow for the full exercise of managerial prerogative and attendant internal flexibility in workforce deployment, and, second, they constitute an effective device to deliver training and develop skills.     

Family Characteristics and Mate Selection: Evidence From Computer‐Assisted Dating in Japan

Research on mate selection rarely considers singles' preferences for their future partners' family configurations and experiences. Using online dating records from a matchmaking agency in Japan, a society with a strong emphasis on family and kinship, we examine how singles' responses to date requests correspond to potential mates' family circumstances. Results showed that singles' preferences for potential partners' family characteristics stem from a concern about future obligations toward the partner's family and stereotypes associated with certain family traits. Singles are less likely to accept requests from those from large families, which are seen as traditional. Being from a large family, however, hampers individuals' dating chances more if they are firstborn and have no brothers, two conditions that make them the designated child to care for elderly parents. We also find that Japanese singles seek partners with more of the universally valued family traits rather than traits similar to their own.     

京津冀人口集聚对能源消费的影响

京津冀作为我国重要的人口集聚区,其区域发展面临严重的能源和环境问题。首先,基于STIRPAT模型构建京津冀面板数据模型,研究1990—2017年京津冀人口密度、经济增长、产业结构和环境规制对能源消费的影响。其次,采用SVAR模型通过脉冲响应函数和方差分解,研究京津冀人口密度变动对能源消费的作用机理和动态影响关系。结果显示,京津冀三地的人口密度、人均实际GDP与能源消费之间存在正向影响关系,其中河北省影响系数最大;北京和天津第三产业占比与能源消费之间存在反向影响关系,河北省第三产业占比对能源消费的影响不显著;北京和天津的环境规制对能源消费影响不显著,河北省环境规制对能源消费具有正向影响;京津冀地区和京冀两地人口密度变动对能源消费的影响在短期呈现负向效应,但是在中长期京津冀地区和三地人口密度变动对能源消费的影响均先上升然后缓慢下降,人口集聚具有集约用能效应。相对于能源消费自身影响而言,京津冀人口密度变动对能源消费的贡献相对较小,其影响效应有限。最后,对京津冀人口流动和能源消费一体化协同发展提出对策建议。     

煤炭上市公司资本结构与公司成长性研究

文章以沪深两市2015-2018年的煤炭上市企业数据为研究样本，研究煤炭企业资本结构和成长性之间的关系，采用因子分析法和线性回归的方法，从盈利能力，短期偿债能力，资产营运水平，发展能力四个方面反映企业成长性，最终得出盈利能力，短期偿债能力和资产营运水平和企业成长性之间存在着负相关的关系，这对促进煤炭企业构建合理资本结构，降低企业财务风险，保证企业经营目标有着实际意义。     

政府减排目标、产业结构与污染减排

政府是污染减排的重要主体,了解其行为对污染减排的作用对提升污染减排效果及实现中国绿色发展具有重要意义。创造性地将政府减排目标纳入研究框架,构建面板门槛模型,从工业污染排放总量的角度分析政府减排目标、产业结构、经济规模等因素对地方污染减排的影响,并用工业污染物强度进行稳健性检验。结果显示,政府减排目标对污染减排的作用存在阶段性不同:经济发展初级阶段,政府减排目标对污染排放总量的作用方向为正; 经济发展水平较高时,作用方向为负; 两者之间存在适应性调整阶段,作用方向具有不确定性,但总体由正向作用向负向作用转变。产业结构对工业污染排放总量的作用方向因污染物种类而异,经济规模对工业污染排放总量作用方向为正。
