高师院校非师范专业人才培养的SWOT分析   总被引:1,自引:0,他引:1  
20世纪80年代以来,我国高师院校纷纷增设非师范专业,与一般院校在教育市场展开了激烈竞争。本文对高师院校非师范专业人才培养进行SWOT分析,对于推进高师院校非师范专业建设具有重要的借鉴意义。  相似文献

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.  相似文献

文章采用博弈论的分析框架探讨了股票流动性的两大效应,即"退出威胁"与"锁定效应".研究表明,当股票流动性较低时,机构投资者的退出策略不可行,被迫参与上市公司的监督行为,即表现为"锁定效应",且股票流动性越低,这一效应越明显.然而,随着股票流动性的进一步增强,机构投资者的退出策略开始变得可信,从而可以通过一定的触发策略迫使管理者选择尽职,因而表现为"退出威胁",且股票流动性越高,这一效应越明显.因此,总的说来,股票流动性与经营绩效之间会呈现一个先减后增的U型关系.文章采用高频交易数据构造相对有效价差与相对报价价差衡量股票流动性对上述假说进行了检验,其实证结论支持了文中的假说.  相似文献

There is substantial evidence to suggest that the book-to-market (BM) ratio is an important factor in explaining stock market returns. Its role has proved difficult to isolate, however, due to statistical problems in its construction and to its observational equivalence to a number of risk and behavioural explanations. In addition, now widely recognised complex behaviour in financial markets has called into question modelling approaches that are limited in their ability to uncover relationships that are possibly masked during financial crises, for example. As one response, our research explores the value of a newly applied technique which examines the topological properties of minimum spanning trees as applied to both the BM ratio and market returns. Our intention is to identify and report investment signals as determined by the BM ratio and to assess the relationships of these signals to returns outcomes. The approach enables highly nonlinear behaviour to be addressed and the relationships we set out to capture to be reported in novel ways. We motivate and evidence a previously unreported role for BM as an investment signal which is effective over varying stock market conditions, including the financial crisis that began in 2008.  相似文献

We propose a semantic patent claim analysis that can examine patents for possible infringements and identify which needs to be manually perused. So far, numerous approaches have been devised to systemise this burden, but have not been useful in practice because of a lack of consideration of semi-structure of patent claim data and claim element-based procedure of adjudicating patent infringement. At the heart of our method is a hierarchical keyword vector for representing the dependency relationships among claim elements (as well as unstructured textual information) and a tree matching algorithm for comparing claim elements of patents. A case study of the patents about DNA chip technology shows our method has considerable advantages in terms of accuracy and significance. We believe the suggested method could be employed in various research areas and serve as a starting point for developing more general models.  相似文献

In an information economy, the effective management of a massive amount of technological information is inevitable when attempting to facilitate the decision-making process. It is an important part of selecting R&D projects and allocating budgets to promising technology development. Information visualisation is thus regarded as a critical tool in technological information management because it can provide decisive implications that the intelligence of humans cannot produce. This paper proposes six graphical forms, including a technology tree, a technology map, a technology network, a technology matrix, a technology curve, and a technology dictionary, presenting the generic form and concept of each method. Moreover, the principles and applications of such visualisation tools are suggested in order to enhance their use in practical circumstances. A case study of TFT-LCD (thin film transistor-liquid crystal display) technology will help to explain how to apply visualisation tools to strategic technology management.  相似文献

This paper proposes a new model to discover customer value of air passengers by using data mining technologies. The results of this research can be applied in database marketing systems. The procedure applies See5/C5.0 (RuleQuest Research Pty Ltd, St Ives, New South Wales, Australia) decision tree; transaction records; Frequency, Price Discount, Destination and No‐Show (FPDN model; Recency, Frequency and Monetary model based) model variables; and socio‐economic variables to create decision rules for airline business. An empirical case of air passengers' market in Taiwan is implemented for the identification of this procedure and the Frequency, Price Discount, Destination and No‐Show model.
