新形势下引入朋辈辅导机制促进高校后进生转变初探

在当前形势下,90后大学生已经逐渐成为大学校园的主导,他们身上所体现出的张扬个性、崇尚自由、叛逆心理、缺乏信念、缺乏团队精神等特质,对传统的思想政治教育理念提出了新的挑战,对于其中后进生的教育工作更需引入新的机制作为辅助。     

Backward SDEs for control with partial information

This paper considers a non‐Markov control problem arising in a financial market where asset returns depend on hidden factors. The problem is non‐Markov because nonlinear filtering is required to make inference on these factors, and hence the associated dynamic program effectively takes the filtering distribution as one of its state variables. This is of significant difficulty because the filtering distribution is a stochastic probability measure of infinite dimension, and therefore the dynamic program has a state that cannot be differentiated in the traditional sense. This lack of differentiability means that the problem cannot be solved using a Hamilton–Jacobi–Bellman equation. This paper will show how the problem can be analyzed and solved using backward stochastic differential equations, with a key tool being the problem's dual formulation.     

西安“黄帝都邑”杨官寨遗址探析——再论西安古都史达5000年并与黄帝时期“关中落后论”商榷

文章从考古—文化学角度,探讨西安"黄帝都邑"杨官寨遗址并佐证着西安古都史当在5000年以上,认为杨址"陶祖"的出土可证明,在史前女权社会逐渐被男权社会取代的黄帝时期的社会转型中,关中已出现男权社会。在黄帝时期,中国社会、经济和文化发展状况,在总体上是晋陕豫"金三角"地带依然高于辽西。辽西女神庙在社会文化层面上落后于杨址,在文化学上应无疑义。苏秉琦先生以辽西女神庙为据,明确提出黄帝时期"关中落后论",显然不妥。

感应式智能饮水机控制装置的营销推广

随着人们生活水平的提高,饮水机渐渐走进了千家万户。然而,普通饮水机在水质的保鲜、耗电量、智能控制等方面存在着明显不足,对人类的健康有潜在的危害。在这种情况下。感应式智能饮水机应运而生。感应式智能饮水机与普通饮水机在技术上的主要区别是感应式智能饮水机控制装置。本文分析了目前无锡市场饮水机具有的功能,饮水机消费者对感应式饮水机控制装置的接受程度,在市场调研数据分析的基础上,提出了感应式智能饮水机控制装置的营销推广渠道。     

OPTIMAL INVESTMENT UNDER RELATIVE PERFORMANCE CONCERNS

We consider the problem of optimal investment when agents take into account their relative performance by comparison to their peers. Given N interacting agents, we consider the following optimization problem for agent i, : where is the utility function of agent i, his portfolio, his wealth, the average wealth of his peers, and is the parameter of relative interest for agent i. Together with some mild technical conditions, we assume that the portfolio of each agent i is restricted in some subset . We show existence and uniqueness of a Nash equilibrium in the following situations:

• ‐ unconstrained agents,
• ‐ constrained agents with exponential utilities and Black–Scholes financial market.

We also investigate the limit when the number of agents N goes to infinity. Finally, when the constraints sets are vector spaces, we study the impact of the s on the risk of the market.

Backward Stochastic Differential Equations in Finance

We are concerned with different properties of backward stochastic differential equations and their applications to finance. These equations, first introduced by Pardoux and Peng (1990), are useful for the theory of contingent claim valuation, especially cases with constraints and for the theory of recursive utilities, introduced by Duffie and Epstein (1992a, 1992b).     

中国工业自主创新能力提升的内在机理分析——基于产业外部性的视角

基于产业外部性的视角,研究我国工业技术创新通过技术溢出实现自主创新能力提升的内在机理并加以实证检验。研究结论为:产业间贸易的前向关联对普通创新有明显促进作用,但对创新程度较高的发明作用不明显;产业间贸易的后向关联由于受到产权结构和"被迫引进"现象的负面影响,对自主创新表现出抑制作用;产业集聚对于创新程度较高的发明有明显促进作用,对普通创新作用不显著;进一步考察发现,产业集聚能加强前向关联的技术溢出,并能减轻甚至消除后向关联对创新的抑制作用。
