失去脚后跟:荒诞的生存感

多和田叶子在《失去脚后跟》中以一种奇特的表现方式,抒写了现代人在异域文化冲突中荒诞的生存感受与生存处境,以及人与人之间的扭曲关系。通过对人物心理体验的挖掘和表现手法的分析,以及“失去脚后跟”诸意象隐喻意义的探寻,揭示了现代人的精神困境。     

The impact of random machine unavailability on inventory policies in a continuous improvement environment

There are production situations where a production facility (e.g. a machine) is used intermittently to produce lot sizes of certain products. Upon completion of production run, the facility may not be available for a random amount of time due to several reasons, such as: the facility needs to be maintained and the maintenance time is random due to unforeseen circumstances; or that the facility is leased by different manufacturers and the demand for the facility is random. As a result of machine unavailability, stock-out situations might arise. This paper extends the work of Abboud et al . (2000, Computers and Operations Research , 27 , 335-351) by assuming learning and forgetting in production. A new mathematical model is developed with numerical examples and sensitivity analysis provided. Furthermore, this paper determines how the overall inventory cost is influenced by the nature of the random variable that represents the unavailability time of the production facility.     

直销“异化”风险的法律防范

直销易于＂异化＂为金字塔销售计划的特征,使得直销制度一直难以被人们完全接纳。如何在合理发展直销业的同时,行之有效地杜绝直销＂异化＂,是直销立法所关注的重点问题。文章结合国外的直销立法经验以及我国直销法律政策的演进历程,深入分析目前我国直销法律防范直销＂异化＂的相关规定,并就如何制止目前仍存在的非法传销活动提出相应的建议。     

严歌苓的叙事意识及其《扶桑》的叙事解读

严歌苓的小说《扶桑》令人注目的主要不在于作品的故事,而是它的叙事态度和叙述方式。严歌苓对叙事形式的兴趣和探索使这部小说的叙事呈现出独特的魅力。多种人称的复合叙事和对历史化叙事的刻意追求,是这部作品的重要叙事视角。     

裂缝地层漏失规律研究

本文根据地下裂缝的漏失特性,建立了地下裂缝漏失规律的数学模型,并导出了各种流体在裂缝中的流动挽律。根据流动规律可以定量分析和计算漏速或漏失量与压差、裂缝尺寸、钻井液流变性能等之间的关系,这时优选优配堵漏荆的性能,选择合理的堵漏方法,提高防漏堵漏的成功率具有重要的指导意义。

论《左传》“逸诗”的属性问题——兼驳前人对“古诗三千余”说的质疑

由一系列的考证得知:《左传》中的“逸诗”并不是整部《诗经》的剩余,它们应来自部分政治上的显贵地区。司马迁的“古诗三千余”说并没有错,实是后人误读了《史记》。     

Marketing Category Forecasting: An Alternative of BVAR‐Artificial Neural Networks*

Analyzing scanner data in brand management activities presents unique difficulties due to the vast quantity of the data. Time series methods that are able to handle the volume effectively often are inappropriate due to the violation of many statistical assumptions in the data characteristics. We examine scanner data sets for three brand categories and examine properties associated with many time series forecasting methods. Many violations are found with respect to linearity, normality, autocorrelation, and heteroscedasticity. With this in mind we compare the forecasting ability of neural networks that require no assumptions to two of the more robust time series techniques. Neural networks provide similar forecasts to Bayesian vector autoregression (BVAR), and both outperform generalized autoregressive conditional herteroscedasticty (GARCH) models.     

An Examination of the Effect of Continuous Quality Improvements on Optimal Pricing for Durable Goods*

This paper investigates the nature of optimal prices for a durable good in the presence of continuous quality improvements. The analysis of optimal prices is based on a nonlinear dynamic model of sales response that relates price, quality, average life of a product and the persistence of quality perceptions. Numerical solutions to the model are derived by employing the generalized reduced gradient algorithm. The results show that optimal price depends on the persistence of quality perceptions and the average life of a product (an aspect of quality). The analysis of optimal results affirms results based on other models and provides insights on the influence that quality has on optimal pricing. The implications of the results and suggestions for future research are discussed.     

“无神论”在高校失落的原因

当前,有不少大学生有迷信心理和行为。"无神论"在高校的失落,与思想政治教育的弱化、转型期社会的迷惘、科学技术的消极影响、媒体不负责任的宣传和发达国家的文化殖民以及大学生自身价值观有关,对此必须加以有效防范,从中也可以看出,大学生思想教育工作还需进一步加强。
