人力资本、雇佣制度与职工持股问题研究

随着科学技术的进步和现代企业制度的发展,人力资源日益资本化了,即人力资源转化为人力资本。与此相适应,企业的雇佣制度也开始发生变化,已经或将要从单向的资本雇佣劳动转变为资本与劳动相互雇佣的制度,或者转变为劳动者自我雇佣的制度,即劳动者自己的资本雇佣自己劳动的制度。人力资源性质和企业雇佣制度的这种革命性变革的集中表现,就是职工持股制度在世界各国的普遍建立和扩展。我国的职工持股制度形成的时间还不长,并且带有很大特殊性,还有若干重要理论与实际问题迫切需要解决。

试论新闻策划的合力导向

加入WTO之后 ,国内媒体要想做大、做强 ,加大在国际上的声音 ,必须加强新闻策划 ,必须强调新闻合力 ,因此 ,研究新闻策划的合力导向是十分重要的。事实证明 ,媒介合力导向的传播效果来自于精深的策划 ,同样 ,新闻策划也需要发挥合力导向的作用 ,两者相辅相成 ,共同促进。在新闻策划的合力导向实施过程中 ,应遵循导向正确的原则、集思广益的原则、慎重筹划的原则以及目标整合的原则 ,以保证新闻传播事业能够形成整体功能和综合效应 ,使影响新闻事业效果的各个因素朝着正确的方向、沿着最佳的路线协调一致 ,同步前进。     

论魏徵的治国方略

魏徵是唐朝杰出的政治家和著名学者,他对初唐国力的恢复与社会政治的清明作出了贡献。唐太宗李世民与魏徵在治国大事中配合默契,相得益彰,是“贞观之治”开明盛世得以出现的重要原因。治理国家历来是政治家与关心国家大事的有识之士思考的重大问题,魏徵关于治国的许多言行已成为以后诸多有识之士的借鉴。他深刻指出,德、礼、诚、信为治国大纲,关系治国成败;居安思危,特别强调朝廷与其下属百姓关系的和谐;考察官员的实际政绩,由其政绩优劣来决定对其升降;帝王能听进逆耳忠言,大臣敢进谏逆耳忠言,均很难做到,但对治国关系重大。     

"主义"三元素:价值、道理、方案--对人文社会学说性质的审查

文章不研究这个“主义”或那个“主义” ,而以“主义”之为“主义”作为探讨对象。凡被称为“主义”的 ,一般都是那种已具有相当影响的人文社会学说。这些学说往往既揭示某种道理 (即客观联系 ) ,又宣扬某种价值目的 ,还设计某种操作方案 ,并且将这三者构造为一套逻辑体系。对这种做法 ,大家已经习以为常。但文章认为 ,道理、价值和方案是三种在逻辑上不能相互还原的元素 ,有关道理的思维方式必须是合逻辑的 ,而有关价值和方案的思维方式则应当是非逻辑的 ,其间不存在推导关系 ,人文社会学说将它们逻辑地结为一体在思维方式上是错误的。据此 ,应对道理、价值和方案三元素加以离析 ,人文社会学说应以揭示道理为主 ,而不再包办一切 ,价值的事情应由价值主体参照各种价值资源自行决定 ,方案的问题应由方案的当事人求助工程学科加以解决。     

Designing an economically optimal repetitive group-sampling plan based on loss functions

Acceptance sampling is a quality assurance tool, which provides a rule for the producer and the consumer to make acceptance or rejection decision about a lot. This paper attempts to develop a more efficient sampling plan, variables repetitive group sampling plan, based on the total loss to the producer and consumer. To design this model, two constraints are considered to satisfy the opposing priorities and requirements of the producer and the consumer by using Acceptable quality level (AQL) and Limiting quality level (LQL) points on operating characteristic (OC) curve. The objective function of this model is constructed based on the total expected loss. In order to illustrate the application of the proposed model, an example is presented. In addition, the effects of process parameters on the optimal solution and the total expected loss are studied by performing a sensitivity analysis. Finally, the efficiency of the proposed model is compared with the variables single sampling plan, the variables double sampling plan and the repetitive group sampling plan of Balamurali and Jun (2006) in terms of average sample number, total expected loss and its difference with ideal OC curve.     

A Lower Bound for the Wrap-around L2-discrepancy on Combined Designs of Mixed Two- and Three-level Factorials

The objective of this article is to study the issue of employing the uniformity criterion measured by wrap-around L₂-discrepancy to assess the optimal foldover plans. For mixed two- and three-level fractional factorials as the original designs, general foldover plan and combined design under a foldover plan are defined, and the equivalence between any foldover plan and its complementary foldover plan is investigated. A lower bound of wrap-around L₂-discrepancy of combined designs under a general foldover plan is obtained, which can be used as a benchmark for searching optimal foldover plans. Moreover, it also provides a theoretical justification for optimal foldover plans in terms of uniformity criterion.     

Accelerated life test sampling plans for the Weibull distribution under Type I progressive interval censoring with random removals

This paper considers the design of accelerated life test (ALT) sampling plans under Type I progressive interval censoring with random removals. We assume that the lifetime of products follows a Weibull distribution. Two levels of constant stress higher than the use condition are used. The sample size and the acceptability constant that satisfy given levels of producer's risk and consumer's risk are found. In particular, the optimal stress level and the allocation proportion are obtained by minimizing the generalized asymptotic variance of the maximum likelihood estimators of the model parameters. Furthermore, for validation purposes, a Monte Carlo simulation is conducted to assess the true probability of acceptance for the derived sampling plans.     

员工持股计划抑制了企业非效率投资？

员工持股计划重启是我国资本市场助力企业维持人力资源禀赋、建立长效激励机制的一项重要制度安排。以2014—2018年沪深A股上市公司为样本,探究员工持股计划实施对企业非效率投资的影响。研究发现：员工持股计划并未达到抑制企业非效率投资的理想效果,反而加剧了企业的过度投资,但对投资不足的正向影响并不显著;在市场化程度欠发达地区,员工持股计划与非效率投资的正向效应更为显著;进一步分析发现在大股东定向受让、股东赠予方式下,高管认购比例能够显著抑制企业的过度投资。研究结论证实了当前我国员工持股计划长期激励效应不足的现状,为监管层完善相关制度提供了理论支撑,同时对投资者决策具有一定的警示作用。
