高校共青团团员意识教育长效机制建立研究

高校团员数量占学生总数的95%以上,团工作的优劣,团员表现的好坏直接影响着学校的整体工作.当前在全团开展增强团员意识主题教育活动,是共青团加强自身建设的一项重大战略举措.构建团员意识教育的长效机制,有利于长期深入广泛地开展团员意识教育工作,要从思想教育、组织建设、团务管理和"党建带团建"等方面去考虑.     

自主创业——青年学生就业的重要途径

在未来一段时期,我国面临的就业压力依然很大.要解决大学生就业难,自主创业是一条重要途径.为此,青年学生要注意培养自我创业的意识和企业家精神.学校应建立学生创业长效机制,在课程设置等方面加大创业型学生培养力度.近几年来,政府及有关部门,正努力为青年学生自主创业创造良好的外部环境.

论中国早期电影的自由精神

中国早期电影突破传统模式、打破封建牢笼,善于吸收西方先进文化中所体现的自由价值取向.从电影的选题、创作、以至宣传发行都是独立自由、勇于创新的.早期电影深受多元文化的影响,直接倡导自由精神,鞭笞落后反动的旧式习俗思潮,这一切为早期中国电影的发展注入了无限活力,对整个社会也产生了深远的影响.     

A Decision Model for the Robot Selection Problem Using Robust Regression*

Industrial robots are increasingly used by many manufacturing firms. The number of robot manufacturers has also increased with many of these firms now offering a wide range of models. A potential user is thus faced with many options in both performance and cost. This paper proposes a decision model for the robot selection problem. The proposed model uses robust regression to identify, based on manufacturers' specifications, the robots that are the better performers for a given cost. Robust regression is used because it identifies and is resistant to the effects of outlying observations, key components in the proposed model. The robots selected by the model become candidates for testing to verify manufacturers' specifications. The model is tested on a real data set and an example is presented.     

Standard Container Size Discounts and the Single-Period Inventory Problem*

This paper analyzes the problem of choosing the optimal order quantity and its associated number of standard containers making up the order for single-period inventory models under standard container size discounts. A range is determined that contains the optimal order quantity. Two algorithms are presented. The first algorithm solves the general case in which there is no restriction on the types of containers included in an order. The second algorithm solves a more restricted policy that requires the buyer to accept the order with successively smaller container sizes.     

Graphical Presentations of Data Envelopment Analyses: Management Implications from Parallel Axes Representations*

The conversion of multivariate data analysis into information that managers can readily use in their decision making has always been a challenging task. In this paper we provide a parallel axis representation of multivariate data and demonstrate how this representation may be used as a tool for implementing the results of data envelopment analysis. We use an analysis of the efficiency of electricity generating plants to illustrate the technique.     

Resource Flexibility Issues in Multistage Manufacturing

We test the situational impact of two types of resource flexibility, machine flexibility and labor flexibility, in a material requirements planning (MRP)-driven production system. Machine flexibility has not been treated in prior multistage research, only labor flexibility. Machine flexibility is closely related to a plant's positioning strategy. A process-focused plant opts for considerable machine flexibility by choosing general-purpose equipment. Resource flexibility, if effective, can be an attractive alternative to two other types of buffers, inflated inventories and costly capacity cushions. Our simulation results, using factor settings established earlier by a panel of managers, show that resource flexibility is indeed an effective buffer against uncertainties such as end-item demand variability, capacity bottlenecks, equipment failures, and yield losses. Machine flexibility is especially helpful in environments characterized by high uncertainties, tight capacities, and large lot sizes. Worker flexibility has a similar, but less dramatic, impact. Benefits are most striking with customer service, rather than with inventory or labor productivity. Finally, we show that simultaneous introduction of both machine and labor flexibility yields only marginal improvements over either kind of flexibility alone.
