都市娱乐类传媒言说风格刍议

由于对受众的想象存在着文化低端化定势,当下都市娱乐类传媒大量采用了流行言语和时尚言说方式,形成一种夸张、油腻、生僻化、雷同的言说风格。这种言说风格通过持续而广泛的传播,正在影响着我们的语言规范,其更深的社会文化背景则是公众心态的普遍浮躁和对语言规范的解构。若不注意控制这种言语文风,将对语言体系的健康发展产生过多的噪音。     

Flow shop scheduling with deteriorating jobs under dominating machines

This paper addresses no-wait or no-idle flow shop scheduling problems with deteriorating jobs, i.e., jobs whose processing times are an increasing function of their starting time. A simple linear deterioration function is assumed and some dominating relationships between machines can be satisfied. It is shown that for the problems to minimize makespan or weighted sum of completion time, polynomial algorithms still exist, although these problems are more complicated than the classical ones. When the objective is to minimize maximum lateness or maximum tardiness, the solutions of a classical version may not hold.     

社会主义荣辱观的学理意义与媒体策略

以“八荣八耻”为内容的社会主义荣辱观适合时宜的提出,体现了时代发展的新要求,是对人类社会主义历史阶段荣辱观的创造性发展。它对扼制人精神生态的恶化,将起到根本性的作用。学术生态的恶化,过分强调生活方式选择的自由性,片面强调“各人有各人的活法”,这就为丑陋的生活方式和颓废的生活行为提供了理论上的帮助,成为荣辱倒置的思想器具。因此,学术期刊应以马克思主义的文风、学风和作风,为社会主义荣辱观的建设提供理论与智力支持,要尊重媒体传播规律,突出特色,创造性地使以“八荣八耻”为内容的社会主义荣辱观深入人心。

Optimizing inventory and marketing policy for non-instantaneous deteriorating items with generalized type deterioration and holding cost rates

This paper considers an inventory system with non-instantaneous deteriorating item in which demand rate is a function of advertisement of an item and selling price. This paper aids the retailer in maximizing the total profit by determining optimal inventory and marketing parameters. In contrast to previous inventory models, an arbitrary holding cost rate and arbitrary deterioration rate have been incorporated to provide general framework to the model. First, a mathematical model is formulated and then some useful theoretical results have been framed to characterize the optimal solutions. The necessary and sufficient conditions for the existence and uniqueness of the optimal solutions are also derived. An algorithm is designed to find the optimum solutions of the proposed model. Numerical examples are included to illustrate the algorithmic procedure and the effects of key parameters are studied to analyze the behavior of the model.

以什么标准来评判抗战期间的中苏关系--论抗战期间中苏关系恶化的原因

评判抗战期间中苏关系中是与非的标准只能是国家利益和主权.抗战期间中苏关系曲折发展,以致恶化而发生军事冲突的根本原因,是中苏两国的利益冲突,其中更为主要的是苏联对华政策中的严重民族利己主义和大国沙文主义.

Postponement implementation in integrated production and inventory plan under deterioration effects: a case study of a juice producer with limited storage capacity

Abstract

The aim of this study is to develop a production and inventory plan for a fresh apple juice producer. During harvest season, the producer extracts premium juice from freshly picked apples and keeps an inventory of these premium apples in his temperature-controlled storage facility. The producer extracts also regular juice from regular apples purchased from third-party storages. To satisfy future demand, the producer carries inventories of juice and apple. The levels of apple inventories are constrained by the producer’s limited storage space, but he can replenish regular apples. To assist the producer in facing demand uncertainty and deterioration of apples, we develop a production and inventory plan that incorporates postponement to mitigate demand uncertainty. As postponement decisions are shaped by the cost structure of inventories, we integrate in one model the postponement decisions and the deterioration mitigation decisions that can alter the inventory costs. We build multi-period stochastic programming with recourse model to determine juice batch sizes and apple inventories that maximize the producer’s expected profit. The optimal solution illustrates the use of time and form postponements. We discuss the interactions between postponement implementation and decisions to mitigate apples deterioration. We compare the production and inventory plans with and without postponement and with and without apple deterioration. We also present sensitivity analyses for the plan under varying inventory cost and storage space.     

The effect of preservation technology investment on a non-instantaneous deteriorating inventory model

Considering an inventory system with a non-instantaneous deteriorating item, our objective is to study the effect of preservation technology investment on inventory decisions. The generalized productivity of invested capital, deterioration and time-depend partial backlogging rates are used to model the inventory system. The basic results of fractional programming are employed to prove the uniqueness of the global maximum for each case. We also establish several structural properties on finding the optimal replenishment and preservation technology strategies. Further, we use a couple of numerical examples to illustrate the results and conclude the paper with suggestions for possible future researches.
