丑角、看客与孤独者的悲喜剧 ——鲁迅与穆时英笔下的丑角形象之比较

鲁迅与穆时英笔下都塑造过一系列具有丑角特质的形象。不同的是,穆时英笔下的丑角具有自觉性,以小丑身份为面具,掩盖自己的孤独与恐惧；鲁迅笔下的丑角多是非自觉的,他们认真地践行着自己的人生理念,却因其与周遭环境格格不入,被人当作小丑、疯子。从中折射出两位作家迥异的生命观,穆时英从个体角度出发,写出了都市人在悲哀的脸上戴了快乐面具的无奈,对丑角表演持拥抱态度；鲁迅则从批判国民性的宏观角度出发,敏锐地意识到了丑角表演背后的隐忧,对其持拒斥的姿态。     

五河民歌的传承机制研究

The Examination of Emotional Facial Expressions Within Parent–Child and Sibling Interactive Contexts: A Systematic Review

This work constitutes a systematic review of the empirical literature about emotional facial expressions displayed in the context of family interaction. Searches of electronic databases from January 1990 until December 2016 generated close to 4400 articles, of which only 26 met the inclusion criteria. Evidence indicate that affective expressions were mostly examined through laboratory and naturalistic observations, within a wide range of interactive contexts in which mother–child dyads significantly outnumbered father–child dyads. Moreover, dyadic partners were found to match each others’ displays and positive and neutral facial expressions proving more frequent than negative facial expressions. Finally, researchers observed some developmental and gender differences regarding the frequency, intensity, and category of emotional displays and identified certain links among facial expression behavior, family relations, personal adjustment, and peer-related social competence.     

Strong convergence rates of probabilistic integrators for ordinary differential equations

Probabilistic integration of a continuous dynamical system is a way of systematically introducing discretisation error, at scales no larger than errors introduced by standard numerical discretisation, in order to enable thorough exploration of possible responses of the system to inputs. It is thus a potentially useful approach in a number of applications such as forward uncertainty quantification, inverse problems, and data assimilation. We extend the convergence analysis of probabilistic integrators for deterministic ordinary differential equations, as proposed by Conrad et al. (Stat Comput 27(4):1065–1082, 2017. https://doi.org/10.1007/s11222-016-9671-0), to establish mean-square convergence in the uniform norm on discrete- or continuous-time solutions under relaxed regularity assumptions on the driving vector fields and their induced flows. Specifically, we show that randomised high-order integrators for globally Lipschitz flows and randomised Euler integrators for dissipative vector fields with polynomially bounded local Lipschitz constants all have the same mean-square convergence rate as their deterministic counterparts, provided that the variance of the integration noise is not of higher order than the corresponding deterministic integrator. These and similar results are proven for probabilistic integrators where the random perturbations may be state-dependent, non-Gaussian, or non-centred random variables.

     

Policy innovation and policy realisation: the example of children future education and development accounts in Taiwan

ABSTRACT

The Children Future Education and the Development Accounts (CFEDAs) are the first anti-poverty policy in Taiwan developed to provide incentives for the poor to accumulate assets for their future. Using CFEDAs as an example, this article analyses the process of developing and implementing an asset-based policy. It begins with an introduction to the policy structure. It then reviews the history of how the innovative idea of building assets for the poor became a policy proposal before presenting the convergence of three policy streams driving the prioritisation of CFEDAs in Taiwan’s policy agenda. It concludes with challenges facing the policy implementation.     

多层供应链外包模式的选择及其协调

本文研究由两个原始设备制造企业（品牌企业）、一个代工企业和一个供应商组成的多层供应链的外包模式选择问题。应用主从博弈和纳什博弈理论，当一个原始设备制造企业的外包模式给定后，通过对不同外包模型求解比较，给出了后跟进的原始设备制造企业外包模式的最优选择策略。研究发现：后跟进的原始设备制造企业最优策略应采取与前一个原始设备制造企业相同的外包策略。针对最优外包策略，还设计了使供应链达到协调的二部定价契约机制，提高了外包供应链的竞争力。     

The intergenerational education spillovers of pension reform in China

Economic theory establishes that pension privatization weakens the link between old and young and so reduces the incentive to invest in public education in an economy with lower return rate of capital than growth rate of wage. However, empirical studies of the link change are few. In this paper, we investigate the effects of pension privatization and the central government’s subsidy to individual accounts on public education spending in a three-period overlapping generation model. And then, we take contemporary pension reforms in a number of Chinese provinces as offering natural experiment conditions. Using a difference-in-difference framework and 282 municipal districts panel data over years 1998–2009, we test the pension-education theoretical link change. Both our theoretical and empirical results confirm that pension privatization is adversely associated with local public spending on education in China. Private pension subsidies, moreover, magnify this effect. Our study supports the theoretical assertion and selective empirical findings of a negative intergenerational effect of pension privatization.     

遗产动机对中国老年家庭储蓄率的影响

中国人口老龄化问题日益凸显,老年家庭储蓄率居高不下,标准生命周期假说理论已无法解释。基于中国家庭金融调查数据,从遗产动机视角分析老年家庭高储蓄率现象。研究结果表明,中国老年家庭遗产动机显著提升家庭储蓄率,遗产动机使得老年家庭储蓄率水平显著提高5%—10%左右。进一步研究发现,相比较于城市家庭,遗产动机对农村家庭储蓄影响显著;相对于高等财富家庭而言,遗产动机显著促进中低财富家庭储蓄率水平,说明“未富先老”使得老年家庭有更强的遗产动机进行储蓄;对于家庭不同生活状况的子女,遗产动机显著提升子女体制外工作和子女教育水平低的老年家庭储蓄率,表明中国老年家庭利他主义的遗产动机较强。本文为理解中国老年家庭的高储蓄提供了新的视角,可以为政府相关部门制定政策提供参考。     

The heterogeneous impact of pension income on elderly living arrangements: evidence from China’s new rural pension scheme

This paper investigates the impact of pension income on living arrangements of the elderly. Taking advantage of a unique opportunity due to the recent establishment and expansion of the New Rural Pension Scheme in China, we explicitly address the endogeneity of pension status and pension income through a fixed-effect model with instrumental variable approach by exploiting exogenous time variation in the program implementation at county level. We find an overall positive effect of pension income on independent living as well as considerable heterogeneity. The positive income effects of the NRPS are concentrated among the elderly with adult children living nearby, of higher socio-economic status, and with better health at baseline; for other groups, the effects are insignificant. We also find that more generous programs exhibit larger effects. Our results highlight that living arrangement is multidimensional in rural China.     

Benevolence-dominant,authoritarianism-dominant,and classical paternalistic leadership: Testing their relationships with subordinate performance

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.
