在东方与西方之间——“春树热”的社会背景探析     

钟旭  李英 《贵阳金筑大学学报》2001,(3)

村上春树的小说受欢迎的根本原因是作品深刻揭示了人性中的真善美与假恶丑,演绎了都市社会里的现代人性故事。在社会背景方面,村上的小说反映了处于相同或相似的社会进程中人们的精神状态,类似的生活体验带来的文化认同感是其小说赖以流行的基础。这种现象反映了资本主义文化扩张所具有的全球化倾向正不断消除着异文化间的差异而代之以一种普遍的跨国资本文化。  相似文献

社会转型期教育的认同危机     

徐萍  符宁 《南阳师范学院学报》2005,4(4):80-82

在社会转型的背景下，全球社会正处于一个重新评价和自我怀疑的时期，原来那种学校概念就差不多可以涵盖教育概念的状况已经不能满足一个多元、复杂的社会的需求。多样性是教育的必然选择。  相似文献   

数量结构的自动识别方案     

冯敏萱 《玉溪师范学院学报》2006,22(1):59-62

数量结构是现代汉语中的一个重要组成部分。对于中文信息处理而言,实现其自动识别将对查找中文文本中的重要命名实体有很大的帮助。但从目前的自动识别程序的开放测试结果来看,乃存在错标、漏标等现象。因此,我们在今后的程序的算法设计中还需要进一步的改善。  相似文献   

电子资源用户受益最大化探讨   总被引：6，自引：1，他引：6  

叶新明 《图书情报工作》2006,50(3):84-86

将经济学中的最大化理论运用于图书馆电子资源的采购和服务领域，阐述图书馆电子资源用户受益最大化分为采购预期最大化和效用预期最大化两个层次。提出开展馆外访问服务将使图书馆提供电子资源服务的时间最大化，同时让合法用户在资源内容、时间与空间上的受益最大化，而网络用户个人身份认证则是目前保障其合法用户受益最大化的最有效的方式。  相似文献   

基于既定词表的自适应汉语分词技术研究   总被引：3，自引：0，他引：3  

黄水清  程冲 《现代图书情报技术》2006,1(5):13-17

提出一种汉语分词算法，在给定的分词词表的基础上进行汉语分词时，不但能成功切分出分词词表中已有的词，而且能同时自动识别出分词词表中没有的词，即未登录词。与逆向最长匹配法以及其他未登录词识别算法进行的测试比较表明，该分词算法可以有效地解决大多数未登录词的识别问题，并且能减少分词错误，同时对分词算法的效率基本没有影响。  相似文献   

Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification     

Jenni A. Suomela  Krista Vajanto  Riikka Räisänen 《文物保护研究》2018,63(7):412-422

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.  相似文献

Writer identification approach based on bag of words with OBI features     

Amal Durou  Ibrahim Aref  Somaya Al-Maadeed  Ahmed Bouridane  Elhadj Benkhelifa 《Information processing & management》2019,56(2):354-366

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.  相似文献   

Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献
