大都市文化消费与文化产业发展——以2012上海文化消费为考察对象

作为国际文化大都市,上海的文化消费紧贴时代发展潮流、彰显市民社会精神生活、带动新型经济发展,反映了当下中国文化消费的新趋向。2012年,上海文化消费在体现都市文化消费延续性特征的同时,彰显众多新的面貌:实体性文化消费持续攀升,精神性文化消费正扩大份额,创意性文化消费异军突起、引领全国风尚,综合性文化消费显示出更强生命力。后世博时代的上海,文化消费载体的体系性建构、新型文化消费空间的开拓、市民文化个性与趣味的养成、公共文化服务体系的建立健全、政府和市场双引擎模式的确立等都成为上海文化消费的新特征。上海具有独特的文化资源与区位优势,上海文化消费还有广阔的提升空间。     

美国儿童照顾政策述评——兼论对中国儿童照顾政策的意义

儿童照顾问题关乎儿童及其父母的发展,与整个国家人口素质的提升紧密相关。在中国,儿童照顾问题尚未得到广泛深入的研究。本文梳理和介绍了美国有关政策,并且对完善中国的儿童照顾政策进行了反思。在美国,儿童照顾政策是反贫困政策的一个重要组成部分,以低收入家庭为目标人群,致力于支持父母就业与促进儿童发展。美国学术界的经验研究发现儿童照顾政策对母亲的就业有正面的影响,同时对于学龄前儿童的智识和行为发展也有积极作用。然而,其儿童照顾政策也存在一些问题,例如:覆盖率低、行政和财政缺乏有效整合、对提高服务质量的影响不够、并且存在明显的区域间差异。这些方面的不足影响了政策的效果。综合来看,美国儿童照顾政策的发展为中国解决相应问题提供了行政、财政、以及服务管理方面的经验。     

山西高校创意型传媒人才培养模式

创意型传媒人才是文化创意产业急需的人才。山西高校应积极探索以素质教育和能力教育为体系构建的创意型传媒人才培养模式,努力改变传媒专业设置较为落后、学生素质教育和能力培养差异化不够、学生实习实效性不强和市场需求拉动不足的现状。     

创意型传媒人才激励研究

创意型传媒人才在传媒产业转型与升级中扮演着越来越重要的角色。目前创意型传媒人才的激励明显不足,主要原因是人才培养机制缺乏活力、传媒形态间信息不对称、人才的市场胜任力缺失、薪酬与职能设置不完善。在传媒产业创意生产和服务中,要以人才需要为本,要规范创意的实践,要将绩效考核与个人满足结合起来。基于这三个原则,构建创意型传媒人才激励模式。     

对转让二手房征收个人所得税的探讨

2013年初,国务院出台了房地产宏观调控新政策即“国五条”,其中规定转让二手房须征收20％的个人所得税,引发了舆论的极大关注和争议.从部分地区已出台的落地细则看,政策上并没有多少新内容,缺乏进一步细化和改进的措施,很难从根本上得到有效调控.要解决房地产市场存在的复杂问题,迫切需要建立法律手段、行政手段和经济手段相结合的楼市调控长效机制.

The freight allocation problem with all-units quantity-based discount: A heuristic algorithm

This paper studies a problem encountered by a buying office for one of the largest retail distributors in the world. An important task for the buying office is to plan the distribution of goods from Asia to various destinations across Europe. The goods are transported along shipping lanes by shipping companies, which offer different discount rates depending on the freight quantity. To increase the reliability of transportation, the shipper imposes a quantity limit on each shipping company on each shipping lane. To guarantee a minimum business volume, each shipping company requests a minimum total freight quantity over all lanes if it is contracted. The task involves allocating projected demand of each shipping lane to shipping companies subject to the above conditions such that the total cost is minimized.Existing work on this and related problems employs commercial linear programming software to solve their models. However, since the problem is NP−hard in the strong sense, it is unlikely to be solvable optimally in reasonable time for large cases. Hence, we propose the first heuristic-based algorithm for the problem, which combines a filter-and-fan search scheme with a tabu search mechanism. Experiments on randomly generated test instances show that as the size of the problem increases, our algorithm produces superior solutions in less time compared to a leading mixed-integer programming solver.     

Service and Price Competition When Customers Are Naive

We consider a system of two service providers each with a separate queue. Customers choose one queue to join upon arrival and can switch between queues in real time before entering service to maximize their spot utility, which is a function of price and queue length. We characterize the steady‐state distribution for queue lengths, and then investigate a two‐stage game in which the two service providers first simultaneously select service rates and then simultaneously charge prices. Our results indicate that neither service provider will have both a faster service and a lower price than its competitor. When price plays a less significant role in customers’ service selection relative to queue length or when the two service providers incur comparable costs for building capacities, they will not engage in price competition. When price plays a significant role and the capacity costs at the service providers sufficiently differ, they will adopt substitutable competition instruments: the lower cost service provider will build a faster service and the higher cost service provider will charge a lower price. Comparing our results to those in the existing literature, we find that the service providers invest in lower service rates, engage in less intense price competition, and earn higher profits, while customers wait in line longer when they are unable to infer service rates and are naive in service selection than when they can infer service rates to make sophisticated choices. The customers’ jockeying behavior further lowers the service providers’ capacity investment and lengthens the customers’ duration of stay.     

论先秦时期的霍山神崇拜

先秦时期,霍太山和霍山神的崇拜盛行,霍太山作为历史上的“五镇”之一,在其早期发展中就被赋予了浓厚的人文和历史含义。之后,由霍太山崇拜衍生出的霍山神崇拜形象多变,对霍山神的信仰方式也不尽相同。先秦时期的霍山神崇拜有诸多自身特色,其中对霍山神崇拜影响最大的仍是政治因素。     

跨区域低碳经济协同发展影响因素系统分析

低碳经济的外部性需要各国、各区域的紧密合作,实现跨区域低碳经济协同发展才能达到人类最终的减碳目标。运用ISM(Interpretive Structural Model)分析,从复杂的影响因素及因素链中,找到影响跨区域低碳经济协同发展的表层因素、浅层因素、中层因素和深层因素,为跨区域低碳经济协同发展的实现提供决策参考依据。研究表明:国际趋势及社会舆论、民众环保意识、消费观念、低碳文化是跨区域低碳经济协同发展的根本与关键,政府应主要围绕这些影响因素制定相应的对策和措施,以保障跨区域低碳经济协同发展的顺利进行。
