中国造物艺术史研究中的核心问题 ——以包装艺术史的写作为例

造物艺术史研究之中只有赋予造物艺术史以某种新意义、新价值或者新答案的论著才称得上是具有启迪意义的论著。要做到这一点,既要求研究者必须具备良好的历史意识,更要求其在研究中把握好“源与流”“内容与形式”“历时性与共时性”“造物的因果律”等核心问题。这些问题不仅涉及能否准确把握人类物质文明发展的历史全貌,而且关乎人类历史发展动力和规律中复杂关系的揭示。造物艺术的历史,不只是物态的历史,还是一部与人有关的生产生活史。近年来,造物艺术史研究对这些问题和关系的探索,出现了两个引人瞩目的新变化：一是研究方式从描述转向阐释;二是研究视角从核心转移到了边缘。     

培训为创业创业促就业

近年来,自谋职业、自主创业正日益成为下岗失业人员再就业的重要渠道。但下岗失业人员文化技能水平较低,竞争能力较弱,缺乏创业必备的经营管理知识和能力、技巧,严重影响了他们的再就业和创业活动。创业培训工作的实施,帮助这些下岗失业人员系统学习创业知识与技能,理清创业思路,增强创办企业的能力,提高创业成功率,从而真正实现了以培训助创业,以创业促就业。     

Order consolidation for hierarchical product lines

We consider the batch production of hierarchical product lines in raw material industry where the whole or parts of multiple customer orders may be consolidated and processed in the same batch if their product specifications are compatible. The objective of the problem is to find maximum possible number of batches completely filled up to their capacity. The compatibility relationship among product specifications is represented by a graph called the compatibility graph. If the compatibility graph is an arbitrary graph, the problem is proven to be NP-hard and belongs to Max SNP-hard class. We develop an optimum algorithm for an important subclass of the problem where the graph is a quasi-threshold graph which in fact is the case for producing hierarchical product lines that are often found in raw materials industry.     

Are there more almost separable partitions than separable partitions?

A partition of a set of n points in d-dimensional space into p parts is called an (almost) separable partition if the convex hulls formed by the parts are (almost) pairwise disjoint. These two partition classes are the most encountered ones in clustering and other partition problems for high-dimensional points and their usefulness depends critically on the issue whether their numbers are small. The problem of bounding separable partitions has been well studied in the literature (Alon and Onn in Discrete Appl. Math. 91:39–51, 1999; Barnes et al. in Math. Program. 54:69–86, 1992; Harding in Proc. Edinb. Math. Soc. 15:285–289, 1967; Hwang et al. in SIAM J. Optim. 10:70–81, 1999; Hwang and Rothblum in J. Comb. Optim. 21:423–433, 2011a). In this paper, we prove that for d≤2 or p≤2, the maximum number of almost separable partitions is equal to the maximum number of separable partitions.

论我国货币政策传导机制中的障碍

通过对近年来我国出现的通货紧缩现象的分析 ,可以看到中央银行所采取的稳健的货币政策的内容及其执行状况。经济的不景气不是由于货币供应量不足而是在于货币政策的传导机制的不畅。我们应找出传导机制不畅的原因 ,并提出相应的对策

抗战前河北棉花生产和运销改进述析

20世纪30年代前期,在国民政府、河北省政府、社会团体、金融机关和南开大学的协力合作下,河北开展了棉花品种改良和合作运销运动,并取得了一定的成绩。棉花生产得到了较快的发展,产量位居全国第一,成为河北最为重要的商品农作物;棉花运销也得到了一定程度的改善,棉农因此获益。
