从楚山禅师坐化看佛教死亡超越理论的当代价值

楚山绍琦禅师是明代四川著名高僧,临济宗传人。他的教化与行持紧扣禅宗"直指心性"的宗旨,以"识心为本"的心性禅著称。他坐化圆寂,肉身不坏流存后世。其所言所行以及离世方式展示了佛教的死亡超越理论,对佛教自身社会形象的定位和提升有深刻启示,并对当代临终关怀、安乐死等诸多生命伦理难题的应对具有启发价值。     

Changepoint Estimation in a Segmented Linear Regression via Empirical Likelihood

For a segmented regression system with an unknown changepoint over two domains of a predictor, a new empirical likelihood ratio statistic is proposed to test the null hypothesis of no change. Under the null hypothesis of no change, the proposed test statistic is shown empirically to be Gumbel distributed with robust location and scale estimators against various parameter settings and error distributions. A power analysis is conducted to illustrate the performance of the test. Under the alternative hypothesis with a changepoint, the test statistic is utilized to estimate the changepoint between the two domains. A comparison of the frequency distributions between the proposed estimator and two parametric methods indicates that the proposed method is effective in capturing the true changepoint.     

大学教学价值取向:历史与现实

从影响当前大学教学方方面面的价值取向看,大学教学要坚守古代的"理智培育"价值取向,这是大学教学永葆魅力的根源所在.同时,大学教学要张扬现代的"技术获取"价值取向,这是作为生活世界现象的大学教学的重要使命之一.第三,大学教学要倡导后现代的"欲望释放"价值取向,这是大学教学充满生机与活力的保证.因此,大学教学价值取向并非还原为欲、技、道中的某一维,而是这三者的有机统一.     

知识社会价值的二重性表现

知识的社会价值具有二重性表现。从生产方式、经济发展和精神文明三个维度阐述了知识社会价值的三个正面性表现，同时从人体自身认识、人类生物性功能、人类文化、人类存在方式与安全性等方面对知识社会价值的负面性表现作了探索，认为，在知识发展过程中，知识社会价值的正面性和负面性在人的交往实践活动中构成一个辩证运动。     

Cautious Expected Utility and the Certainty Effect

Many violations of the independence axiom of expected utility can be traced to subjects' attraction to risk‐free prospects. The key axiom in this paper, negative certainty independence ([Dillenberger, 2010]), formalizes this tendency. Our main result is a utility representation of all preferences over monetary lotteries that satisfy negative certainty independence together with basic rationality postulates. Such preferences can be represented as if the agent were unsure of how to evaluate a given lottery p; instead, she has in mind a set of possible utility functions over outcomes and displays a cautious behavior: she computes the certainty equivalent of p with respect to each possible function in the set and picks the smallest one. The set of utilities is unique in a well defined sense. We show that our representation can also be derived from a “cautious” completion of an incomplete preference relation.     

The Effects of Multitasking on Operations Scheduling

This study considers a typical scheduling environment that is influenced by the behavioral phenomenon of multitasking. Under multitasking, the processing of a selected job suffers from interruption by other jobs that are available but unfinished. This situation arises in a wide variety of applications; for example, administration, manufacturing, and process and project management. Several classical solution methods for scheduling problems no longer apply in the presence of multitasking. The solvability of any scheduling problem under multitasking is no easier than that of the corresponding classical problem. We develop optimal algorithms for some fundamental and practical single machine scheduling problems with multitasking. For other problems, we show that they are computationally intractable, even though in some cases the corresponding problem in classical scheduling is efficiently solvable. We also study the cost increase and value gained due to multitasking. This analysis informs companies about how much it would be worthwhile to invest in measures to reduce or encourage multitasking.     

数字货币时代的商业模式讨论--基于双案例的比较研究

本文运用对比案例分析法,选取Steemit论坛和知乎论坛作为分析对象,探究了使用数字货币与否对同一行业组织的商业模式及其创新有什么影响。本文以商业模式画布为蓝本,通过对比数字货币背景下商业模式在价值主张、价值创造、价值传递、价值网络和价值实现五个方面的差异,探究数字货币时代下商业模式的创新影响,以及商业模式不同价值元素间新的构成秩序。本研究分析了选取案例商业模式中的不同对应元素,并给出了以下三个针对数字货币和商业模式的新命题:第一,数字货币在价值创造过程中联结利益主体;第二,数字货币起到了模糊价值网络边界的作用,从而促进构成新的治理模式;第三,使用数字货币可以在价值实现过程中完成利润重新分配。最后,文章认为数字货币情景下商业模式中不同价值元素的交互关系,呈现出以客户关系为核心的共同价值创造和共同价值实现的新秩序。     

基于EaR的上市商业银行财务风险评价研究

商业银行在我国经济发展和转型中起着重要作用,近年来随着经济增速放缓、利率市场化和同业竞争加剧的影响,商业银行面临的财务风险也不断加大。为了科学合理地评价商业银行的财务风险,本文从在险价值(VaR)的概念出发引入了在险值的财务风险评价方法对上市商业银行的在险盈余和在险现金流进行测度,实证结果表明目前商业银行总体具有良好的盈利水平,但部分商业银行存在现金流风险。     

对历史以及历史认识的再思考?

什么是历史以及历史认识是否可信,一直是史坛争论的焦点。《说文解字》、《中国历史研究法》、《史学导论》都分别做出了自己的解答。而事实上,过去的一切皆为史;而历史认识也只是相对真理,历史实际的纷繁复杂性、史料的不完整性和待考究性以及历史认识的主体性,都决定了不能完全认识历史。但历史认识仍然具有不可替代的价值。
