台湾社区总体营造的运行模式探析

台湾在二十世纪的八十年代末至九十年代,特别是在解除戒严体制之后,越来越多的人开始关心他们所居住的社区,出现了所谓的社区总体营造。及至至今,台湾的社区总体营造可谓风生水起,对台湾的发展,特别是台湾人民的生活起到了非常重要的作用。在当今经济社会全球一体化的大背景下,台湾社区总体营造模式能成功实施并延续至今,这对于大陆地区所开展的新农村建设具有重要的借鉴价值。     

铸牢中华民族共同体意识的法治实践路径研究

根据第五次中央民族工作会议的指导精神,中华民族共同体的法治建设与铸牢中华民族共同体意识是交叉同构的, 需在习近平法治思想和马克思主义多民族国家建设理论的基础上,探析铸牢中华民族共同体意识的法治实践路径。 第一,可 建设权利本位与义务本位相协调的中华民族法制共同体。 第二,应以党的领导为统领推进民族事务治理法治化。 第三,需以 立法、执法、司法为统筹全面深化法治实践。 第四,可通过法治教育为媒介巩固共有法治精神家园。 总之,法制共同体是中华 民族为人类历史转向所优化的现代法治范式,法治为铸牢中华民族共同体意识提供了制度实践基础,彰显了依法治国背景下 “德法共治”的平衡。     

Social mobility and demand for redistribution in Europe: a comparative analysis

The literature on preferences for redistribution has paid little attention to the effect of social mobility on the demand for redistribution and no systematic test of the hypotheses connecting social mobility and preferences for redistribution has yet been done to date. We use the diagonal reference model to estimate the effect of origin and destination classes on preferences for redistribution in a large sample of European countries using data from the European Social Survey. Our findings are consistent with the logic of acculturation in the sense that newcomers tend to adapt their views to those of the destination class at early stages and that upward and downward mobility do not have distinctive effects on the formation of political preferences. However, even though social origins seem to have a limited impact on preferences for redistribution, the evidence does not support the hypothesis that mobile and non‐mobile individuals are alike. We also find that the effect of social origin on preferences varies largely across countries. The empirical evidence leads to the conclusion that the effect of social origin on preferences for redistribution increases in contexts of strong familism.     

The turn to optional familialism through the market: Long‐term care,cash‐for‐care,and caregiving policies in Europe

Cash‐for‐care (CfC) schemes are monetary transfers to people in need of care who can use them to organize their own care arrangements. Mostly introduced in the 1990s, these schemes combine different policy objectives, as they can aim at (implicitly or explicitly) supporting informal caregivers as well as increasing user choice in long‐term care or even foster the formalization of care relations and the creation of care markets. This article explores from a comparative perspective, how CfC schemes, within broader long‐term care policies, envision, frame, and aim to condition informal care, if different models of relationships between CfC and informal care exist and how these have persisted or changed over time and into which directions. Building on the scholarly debate on familialization vs. defamilialization policies, the paper proposes an analytical framework to investigate the trajectories of seven European countries over a period of 20 years. The results show that, far from being simply instruments of supported familialism, CfC schemes have contributed to a turn towards “optional familialism through the market,” according to which families are encouraged to provide family care and are (directly or indirectly) given alternatives through the provision of market care.     

Machine Learning Vasicek Model Calibration with Gaussian Processes

In this article, we calibrate the Vasicek interest rate model under the risk neutral measure by learning the model parameters using Gaussian processes for machine learning regression. The calibration is done by maximizing the likelihood of zero coupon bond log prices, using mean and covariance functions computed analytically, as well as likelihood derivatives with respect to the parameters. The maximization method used is the conjugate gradients. The only prices needed for calibration are zero coupon bond prices and the parameters are directly obtained in the arbitrage free risk neutral measure.     

Generalised K-S confidence regions: some exact results

One-sided confidence regions for continuous cumulative distribution function are constructed using empirical cumulative distribution functions and the generalized Kolmogorov-Smirnov distance. The band width of such regions becomes narrower in the right or left tail of the distribution. Significance levels necessary for implementation are given. Some other K-S type distances useful in constructing a confidence region with nonconstant width are also included.     

论中日茶道文化的意境与精神气质

中日茶道文化是东方文化中的两朵奇葩,但是由于诸多原因,中日茶道文化在意境和精神气质上有着较大区别:中国的茶道仪式自然随和,圆润融通,日本的茶道仪式则过于拘于程序和礼节;中国将饮茶发展为日常生活艺术,日本则将饮茶变为俨然清规;中国茶文化是雅俗共赏的大众文化,日本茶文化则是高高在上的仪式文化。     

Optimal control strategies for dividend payments and capital injections in compound Markov binomial risk model with penalties for deficits

We consider the compound Markov binomial risk model. The company controls the amount of dividends paid to the shareholders as well as the capital injections in order to maximize the cumulative expected discounted dividends minus the discounted capital injections and the discounted penalties for deficits prior to ruin. We show that the optimal value function is the unique solution of an HJB equation, and the optimal control strategy is a two-barriers strategy given the current state of the Markov chain. We obtain some properties of the optimal strategy and the optimal condition for ruining the company. We offer a high-efficiency algorithm for obtaining the optimal strategy and the optimal value function. In addition, we also discuss the optimal control problem under a restriction of bounded dividend rates. Numerical results are provided to illustrate the algorithm and the impact of the penalties.     

Social capital of entrepreneurs in a developing country: The effect of gender on access to and requests for resources

This paper addresses gender differences in the social capital of entrepreneurs in a developing country. Social networks are often an important asset for accessing resources; however, they may also be a liability in developing countries, since entrepreneurs are often expected to support their contacts. Using a recent survey among urban and rural Ugandan entrepreneurs, we focus on the financial resources that entrepreneurs can obtain from their contacts on the one hand, and requests for financial support made to the entrepreneurs from these contacts on the other hand. Our results show that there are gender differences associated with access to, and requests for, financial resources.
