一般工科院校非英语专业大学生英语学习策略调查

本文运用定量研究的方法,调查了南昌航空工业学院509名非英语专业本科生英语学习策略.结果发现,一般院校非英语专业本科生在管理观念和策略、母语观念和策略功能操练观念和策略上存在很大问题,投入于英语学习的时间严重不足. 据此本文提出大学英语教学应以策略培训为基础,用英语教学,培养英语思维能力,强化学习动机.     

维特根斯坦界限主体的三重意蕴——维特根斯坦的主体思想探析

界限主体是维特根斯坦在其逻辑哲学中提出的一种特殊的主体形式,是主体界限化的结果。它区别于意识主体、身体主体、心灵主体等主体形式,是主体的极限情形。界限主体具有逻辑、语言和意志三重意蕴。界限主体的三重性,使形而上学主体与逻辑主体、语言主体、意志主体在某种程度上得到了合理的统一。界限主体的确立,既解决了主体的“体”带来的一系列问题,同时又为主体在逻辑语言的层面上找到了一种合理的存在形式。     

控股股东侵占资金行为的博弈分析

运用博弈论的基本理论,建立一个控股股东与监管部门的博弈矩阵,对控股股东占用上市公司资金的行为进行博弈分析,讨论了控股股东占款的违规成本、违规概率以及监管力度对混合战略博弈纳什均衡的影响,对控股股东处于博弈优势方的现实根源作了深入分析,对有效抑制控股股东的侵占行为提出相应的政策建议。     

进取与迷失:程序员实习生的职业生活

本研究以某外卖公司中程序员实习生的甘愿“被制造”为例，探讨了不稳定工作中的主体性建构问题，发现程序员实习生在互联网行业的训导下，习惯于将自我物化为特定的可计数的劳动产品，或是被认为是职业发展“通行证”的技术等级，并认定只有在互联网企业中而非学校、国企或外企中才能成就这种进取自我。尽管“导师-实习生”的关系以及凸显男性气质的性别游戏也构成了游戏可选择的一部分，但它们非但没有挑战，还在相当程度上强化了进取自我，即不断提升自己技术等级的逻辑。然而，在程序员实习生被循环和无感的时间所蒙蔽，以及私人生活被极大压缩的情况下，进取自我游戏的结果注定是大多数人的自我迷失。

Third-Order Asymptotic Distributions of Classic Test Statistics for One-Parameter Exponential Family Models

ABSTRACT

In this article we derive third-order asymptotic expansions for the non null distribution functions of four classic statistics under a sequence of local alternatives in one-parameter exponential family models. Our results are quite general and cover a wide range of important distributions.     

钢筋混凝土空心剪力墙的拓扑优化设计

传统现浇钢筋混凝土剪力墙结构具有自重大、刚度大、抗震作用大、延性差以及保温隔热性能低等建筑节能性能差等等诸多的缺点.随着建筑业的迅猛发展,大量的试验研究和有限元计算分析表明：钢筋混凝土空心剪力墙刚度小,延性好,是一种很好的节能性的延性剪力墙结构,更适用于高层建筑.本文主要利用ANSYS的结构拓扑优化模块对钢筋混凝土空心剪力墙的拓扑形状进行结构优化设计,建立以总体积为目标函数,以应力和变形状态变量为约束条件,以空心剪力墙孔洞的直径为优化变量的钢筋混凝土空心剪力墙的优化设计模型,并采用零阶方法进行优化设计和计算.     

On a Relation between Principal Components and Regression Analysis

A regression approach to principal component analysis is presented in this note. We provide an alternative interpretation of principal components that illustrates the relation between the extra sum of squares in regression analysis and the eigenvalues associated with the principal components.     

The Impact of Product Returns and Retailer's Service Investment on Manufacturer's Channel Strategies*

We study the distribution channel decision of a manufacturer who considers whether to add an online channel (direct channel) to its brick‐and‐mortar retailer (indirect channel). The retailer faces the opportunity to invest in store assistance to help consumers choose products and thus reduce product returns. Special attention is given to the impact of product returns and retailer's store assistance investment on manufacturer's dual channel decision. We examine conditions under which the manufacturer uses dual channels and how various relevant factors affect its channel decision under two settings, depending on whether the retailer has its own online store or not. When the retailer does not have its online store, we find that (i) the addition of the direct channel raises the wholesale price; (ii) the direct channel addition hurts the retailer if the nonreplacement rate is low; (iii) the manufacturer has a lower incentive to add the direct channel when the retailer's service cost is lower or its returns reduction rate from service investment is higher; and (iv) the manufacturer should treat its own returns handling cost as a key factor in its channel structure decision. In addition, when the retailer operates an online store, we find that the manufacturer may have an incentive to add a direct channel such that both firms own direct channels.
