文学课教学中的审美人生教育

文学教育是一种审美教育,其终极目标不在于培养审美兴趣与审美能力,而在于培养审美人生观。这与文学自身的特性及文学鉴赏的要求有关。在文学课教学中落实审美人生教育应抓住作品的生命意识,强化情感体验,将审美与育人结合起来。     

Learning across the life cycle: Experimentation and performance among the hollywood studio heads

Guided by notions from the literature on organizational learning, this paper investigates how product line experimentation and organizational performance change across the careers of top managers. Its subjects are the studio heads who ran all the major Hollywood film studios from 1936 to 1965. The study found first, that product line experimentation declines over the course of executive tenures; second, that there is an inverse U‐shaped relationship between top executive tenure and an organization's financial performance; and third, that product line experimentation is more likely to benefit financial performance late in top executives' tenures. These findings are consistent with a three‐stage ‘executive life cycle’. During the early years of their tenures, top managers experiment intensively with their product lines to learn about their business; later on their accumulated knowledge allows them to reduce experimentation and increase performance; finally, in their last years, executives reduce experimentation still further, and performance declines.

Progressive stress accelerated life tests under finite mixture models

In this paper, progressive stress accelerated life tests are considered when the lifetime of a product under use condition follows a finite mixture of distributions. The experiment is performed when each of the components in the mixture follows a general class of distributions which includes, among others, the Weibull, compound Weibull, power function, Gompertz and compound Gompertz distributions. It is assumed that the scale parameter of each component satisfies the inverse power low, the progressive stress is directly proportional to time and the cumulative exposure model for the effect of changing stress holds. Based on type-I censoring, the maximum likelihood estimates (MLEs) of the parameters under consideration are obtained. A special attention is paid to a mixture of two Rayleigh components. Simulation results are carried out to study the precision of the MLEs and to obtain confidence intervals for the parameters involved.

Remaining life estimation of used components in consumer products: Life cycle data analysis by Weibull and artificial neural networks

Environmental awareness and legislative pressures have made manufacturers responsible for the take-back and end-of-life treatment of their products. To competitively exploit these products, one option is to incorporate used components in “new” or remanufactured products. However, this option is partly limited by a firm's ability to assess the reliability of used components. A comprehensive two-step approach is proposed. The first stage phase statistically analyzes the behavior of components for reuse. A well-known reliability assessment method, the Weibull analysis, is applied to the time-to-failure data to assess the mean life of components. In the second phase, the degradation and condition monitoring data are analyzed by developing an artificial neural network (ANN) model. The advantages of this approach over traditional approaches employing multiple regression analysis are highlighted with empirical data from a consumer product. Finally, the Weibull analysis and the ANN model are then integrated to assess the remaining useful life of components for reuse. This is a critical advance in sustainable management of supply chains since it allows for a better understanding of not only service requirements of product, but the remaining life in a product and hence its suitability for reuse or remanufacture. Future work should assess: (1) reduction in downtime of process equipment through the implementation of this technique as a means to better manage preventative maintenance; (2) reduce field failure of remanufactured product; (3) selling-service strategy through implementation of the proposed methodology.     

Bayesian life test planning for the Weibull distribution with given shape parameter

This paper describes Bayesian methods for life test planning with Type II censored data from a Weibull distribution, when the Weibull shape parameter is given. We use conjugate prior distributions and criteria based on estimating a quantile of interest of the lifetime distribution. One criterion is based on a precision factor for a credibility interval for a distribution quantile and the other is based on the length of the credibility interval. We provide simple closed form expressions for the relationship between the needed number of failures and the precision criteria. Examples are used to illustrate the results.Received: October 2002 / Revised: March 2004     

德日刑法中的遗弃犯罪及对我国刑法的启示——从一则案例谈起

我国刑法中的遗弃罪之本质在于对公民在家庭中受扶养权利的侵犯，行为人和被害人必须是同一家庭的成员。对于司法实践中发生的非家庭成员之间的严重遗弃行为因无明文规定而无法予以惩治，刑法法益保护之机能也就因此不能实现。有必要借鉴德日刑法相关立法，以完善我国刑法中关于遗弃罪的规定。     

乡村休闲旅游地游客满意度评价研究——以成都市三圣乡幸福梅林为例

以成都市三圣乡幸福梅林为例，研究乡村休闲旅游地的游客满意度评价。研究表明，游客在评价总体满意度时，游客的总体期望差异与总体满意度有较大的相关性，而目的地与游客最佳目的地、其他同类目的地的比较优劣与总体满意度的相关性小；在评价具体评价因子时，游客的期望并不清晰，对具体评价因子感知实绩与满意度的评价差异不显著，感知实绩能有效地反映游客的满意度；游客满意度不仅与游客的推荐意愿正相关，而且也与游客的重游意愿正相关。

基于产品生命周期的高新技术企业融资模式研究

针对高新技术企业在不同生命周期阶段的风险特征及传统融资模式的不足，应采取以高新技术项目为核心、以政府基金为基础、以风险投资为动力、以资本市场为源泉的四元融资模式。该模式不仅适应高新技术企业多产品生产的融资需要，而且可实现多种融资渠道之间的互动。
