双向拍卖机制能较好地解决在线拍卖中如何有效利用网络资源、减轻网络负荷的问题,而构造双向拍卖的报价模型和策略是其重要内容之一。从实验经济学方法的角度,构造了在线双向拍卖中不完全信息博弈下存在的贝叶斯—纳什均衡并求解,通过计算机仿真详细分析了该模型的特点和可行性,为高效利用网络资源、提高在线拍卖效率提供了可行的思路。     

新常态下供销社经营模式的转型与创新研究

随着我国新型四化的深入推进,农村经济建设迈入了新阶段。在新常态下,供销社的迫切任务是加快转型升级,切实提高为农服务能力。因而这就要求我们既要把握好传统业务,又要善用改革和创新的思维开拓新型业务,用业务经营发展促使供销社转型升级。面对我国经济发展新常态,供销社过去长期积累起来的服务“三农”的宝贵经验遇到了很大的挑战,在经营过程中所暴露出的经营方式、手段等方面都存在着很多弊端,进而阻碍了供销社的生存与发展。供销社要想走为农服务的道路,转型与创新势在必行。基于经济发展新常态,分析供销社在发展中存在的突出问题;研究供销社进行转型与创新的必要性;最后归纳总结供销社经营模式的创新途径。     

学前教育专业免费师范男生职业认同感的调查与对策——以泉州幼儿师范高等专科学校为例

运用问卷法和访谈法调查泉州幼高专学前教育免费师范男生的职业认同感现状,结果表明：学前教育专业免费师范男生的职业认同感处于中上水平;不同专业、不同生源地、不同年级的学前教育专业免费师范男生的职业认同感不存在显著性差异;独生的免费男幼师与非独生子女的男幼师在职业认同感存在显著性差异,且非独生子女得分高于独生子女。根据这一结果,从社会、高校、个人三个层面提出对策与建议,为学前教育免费师范男生的培养与管理提供教育启示。     

传统幼儿游戏在农村幼儿数学教育活动中的应用与价值

游戏是幼儿的天性,是幼儿成长发展的需要。幼儿园教育要以游戏为基本活动,寓教育于幼儿的生活、游戏活动中。农村有得天独厚的自然条件,有丰厚的传统幼儿游戏资源,将这些传统游戏应用于幼儿数学教育活动,达成幼儿数学认知目标,是将幼儿数学教育寓幼儿游戏活动路径的有益探索,在农村幼儿园现有条件下有重要的实践意义和理论价值。     

经史之学与清代书院科举文教育

清代书院官学化,很多书院重视科举。有些书院虽从事科举文教育,但不唯之是从,而是将科举文教育与经史之学教育结合起来。此举上溯于中国古代社会推崇经史之学的优良传统,根植于孔子“博学于文”的思想主张,来源于以学术导向矫正利禄歪风的迫切要求。生徒只有学充养邃,才会眼界高、气味厚、笔力健。清代一些书院将科举文教育与经史之学教育结合起来,使得生徒学文不是局限于写作技巧的训练,而是拓展为与炼品、践行、培识的结合。这些书院通过教育,能够为社会培养有用人才。

The governance of social enterprises: Mission drift and accountability challenges in hybrid organizations

We examine the challenges of governance facing organizations that pursue a social mission through the use of market mechanisms. These hybrid organizations, often referred to as social enterprises, combine aspects of both charity and business at their core. In this paper we distinguish between two ideal types of such hybrids, differentiated and integrated, and we conceptualize two key challenges of governance they face: accountability for dual performance objectives and accountability to multiple principal stakeholders. We revisit the potential and limitations of recently introduced legal forms to address these challenges. We then theorize about the importance of organizational governance and the role of governing boards in particular, in prioritizing and aligning potentially conflicting objectives and interests in order to avoid mission drift and to maintain organizational hybridity in social enterprises. Finally, we discuss future research directions and the implications of this work for rethinking traditional categories of organizations, namely business and charity.     

Asymptotic approximations to the distribution of Kendall's sample τ

This paper provides a saddlepoint approximation to the distribution of the sample version of Kendall's τ, which is a measure of association between two samples. The saddlepoint approximation is compared with the Edgeworth and the normal approximations, and with the bootstrap resampling distribution. A numerical study shows that with small sample sizes the saddlepoint approximation outperforms both the normal and the Edgeworth approximations. This paper gives also an analytical comparison between approximated and exact cumulants of the sample Kendall's τ when the two samples are independent.     

Percentage points of the statistics for testing hypotheses on mean vectors of multivariate normal distributions with missing observations

A problem of testing of hypotheses on the mean vector of a multivariate normal distribution with unknown and positive definite covariance matrix is considered when a sample with a special, though not unusual, pattern of missing observations from that population is available. The approximate percentage points of the test statistic are obtained and their accuracy has been checked by comparing them with some exact percentage points which are calculated for complete samples and some special incomplete samples. The approximate percentage points are in good agreement with exact percentage points. The above work is extended to the problem of testing the hypothesis of equality of two mean vectors of two multivariate normal distributions with the same, unknown covariance matrix
