论服装设计大赛与高校服装设计教育的关系

近年来,中国各类服装设计大赛迅猛发展,在为服装行业挖掘设计人才的同时,也为中国高校服装设计教育提供了一个良好的行业氛围。本文通过分析服装大赛与高校服装设计教育之间的关系,总结了各类服装设计大赛的规则设置、评判标准及组织形式,并针对大赛参与各方如何共同进入一个良性的发展空间提出了若干建议。     

基于“3R＆I”原则的循环经济模式研究

我国当前经济高速增长的要求与有限资源和环境支持能力之间存在严重矛盾。实施循环经济是贯彻落实我国节能减排政策的有效途径，如何发展循环经济是我们面临的重大课题。目前循环经济的实施主要是依据“3R”原则，而这些原则有明显的不足之处。针对“3R”原则的局限性，提出基于创新的循环经济“3R＆I”原则。创新是实现“减量化”、“再利用”、“资源化”的前提，也是实现经济持续循环的保证。循环经济本质上是一种创新经济。     

Decomposing the predictive performance of the moving average trading rule of technical analysis: the contribution of linear and non-linear dependencies in stock returns

The main purpose of this work is to decompose the predictive performance of the moving average (MA) trading rule and find out the portion that could be attributed to the possible exploitation of linear and non-linear dependencies in stock returns. Data from the General Index of the Athens Stock Exchange, from the Standard and Poor-500 Index of the New York Stock Exchange and from the Austrian Traded Index of the Vienna Stock Exchange are filtered by linear filters so as the resulting simulated ‘returns’ exhibit no serial correlation. Applying MA trading rules to both the original and the simulated indices and using a new statistical testing procedure that takes into account the sensitivity of the performance of the trading rule as a function of the length of the MA it is found that the predictive performance of the trading rule is clearly weakened when applied to the simulated indices indicating that a substantial part of the rule's predictive performance is due to the exploitation of linear dependencies in stock returns. This weakening is uneven; in general the shorter the MA length the more pronounced the attenuation.

泰罗科学管理中的人本管理分析

泰罗科学管理理论产生已有100多年的历史,人们对该理论的评价也褒贬不一,很多人批评其建立在经济人假设的基础之上,“胡萝卜加大棒”式的管理严重摧残了人性;其实泰罗科学管理理论中的管理职能化思想和人力资源开发思想,就闪烁着人本管理的理性,也给后来的管理以积极的启示,依然具有重要的现实意义.     

Serials Clutter in Online Catalogs

Abstract

Finding and deciphering serials records in online catalogs is a challenge to many library users. To understand and analyze these challenges, the author conducted searches for scientific journal titles in the online catalogs of Committee on Institutional Cooperation (CIC) libraries. The first part of the study measures the difficulty of retrieving serial records from online catalogs comparing one-word versus multiple-word titles. The second part analyzes displays for complexity by measuring the length of the complete record and the length of the holdings statements. These data show the complexity of displays and indicate the potential confusion that these displays may induce in library users.     

Exploring Partial Order of European Countries

Partial Order Theory has been recently more and more employed in applied science to overcome the intrinsic disadvantage hidden in aggregation, if a multiple attribute system is available. Despite its numerous positive features, there are many practical cases where the interpretation of the partial order can be rather troublesome. In these cases the analysis of underlying dimensions could be useful to uncover particular data structures. The paper shows a way of addressing the problem with the help of an actual case study, which deals with European opinions on services of general interest. In particular, a partial order of countries is firstly provided and then a method to detect dimensions is discussed and applied. The analysis stems directly from the Partially Order Set (poset) and Lattice theory with particular references to dimension theory and Formal Concept Analysis. The study is eventually able to pinpoint role and relevance of different attributes characterizing EU countries which are used to define the partial order.

On the improvement of one-sided S control charts

The most common charting procedure used for monitoring the variance of the distribution of a quality characteristic is the S control chart. As a Shewhart-type control chart, it is relatively insensitive in the quick detection of small and moderate shifts in process variance. The performance of the S chart can be improved by supplementing it with runs rules or by varying the sample size and the sampling interval. In this work, we introduce and study one-sided adaptive S control charts, supplemented or not with one powerful runs rule, for detecting increases or decreases in process variation. The properties of the proposed control schemes are obtained by using a Markov chain approach. Furthermore, a practical guidance for the choice of the most suitable control scheme is also provided.     

如何发现DNA是生命的遗传物质

从核酸的发现到DNA双螺旋结构模型建立历时80余年,人类最终确认了DNA是生命的遗传物质,解决了一个生命科学研究中极其关键的重大问题。因此,对此段历史的研究具有重要意义。全面回顾此间发生的对揭示DNA的结构和功能具有重要影响的事件,包括米歇尔发现核酸、列文提出＂四核苷酸假说＂、格里菲斯等人的转化实验、査伽夫提出碱基配对规律,以及沃森和克里克建立DNA双螺旋结构模型,在此基础上阐述人类发现DNA是遗传物质的研究历程,进而探讨科学研究的规律。
