An evaluation framework for cross-lingual link discovery

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9.     

Effective cell collection method using collagenase and ultrasonic vibration

This study proposes a novel cell collection method based on collagenase treatment and ultrasonic vibration. The method collects calf chondrocytes from a reusable metal cell culture substrate. To develop our concept, we calculated the natural vibration modes of the cell culture substrate by a finite element method, and conducted eigenvalue and piezoelectric-structural analyses. Selecting the first out-of-plane vibration mode of the substrate, which has a single nodal circle, we designed and fabricated the cell collection device. The excited vibration mode properly realized our intentions. We then evaluated the cell collection ratio and the growth response, and observed the morphology of the collected cells. The collagenase and ultrasonic vibration treatment collected comparable numbers of cells to conventional trypsin and pipetting treatment, but improved the proliferating cell statistics. Morphological observations revealed that the membranes of cells collected by the proposed method remain intact; consequently, the cells are larger and rougher than cells collected by the conventional method. Therefore, we present a promising cell collection method for adhesive cell culturing process.     

认知心理学视域下体育教学方法分类模式的创新及重构*

通过文献资料、逻辑分析等方法对我国体育教学方法分类体系进行研究,旨在构建以认知心理学知识观为分类标准的体育教学方法分类模式。研究表明:现有体育教学方法分类模式不能为体育教学实践提供足够的支持,运用认知心理学关于知识表征类型的相关研究成果对体育教学目标进行解构,构建了言语图表信息类教学方法、智慧技能类教学方法、认知策略类教学方法和信念类教学方法四级分类模式。该分类模式对促进体育教学方法分类研究的科学化和体育教师合理选择与运用教学方法具有重要意义。     

北周宇文廙、宇文广墓志疏证

新出土《周故大将军西阳昭公墓志》与北周庾信撰《周大将军赵公墓志铭》分别记载了宇文廙和宇文广的生平及家族世系.两位志主为北周皇族嫡亲,曾任秦州刺史一职,其家族对北周王室立下过赫赫战功,与陇右秦州有着很深的渊源.据墓志记载,志主宇文廙籍贯为河南洛阳,与北周皇族出身武川不符,通过考证可知,宇文泰通过建立府兵制、改变皇族及士兵的郡望姓氏,广幕关陇贵族,使得北周在和东魏与梁的斗争中脱颖而出.墓志对于宇文廙籍贯的交代,是北周皇族改郡望之历史确据,和北周建国前期种种政治行为相暗合,为我们深入了解北周的历史提供了可贵的资料.两通墓志的记述较《周书》本传更为详尽,具有重要的学术价值.     

偏序半群的偏序同态和商序同态的若干重要性质

提高公共教育学教学有效性的策略研究

长期以来,高校公共教育学教学一直处于无效或低效状态,原因主要是专业定位出现偏差、教学过程中的教法低效、教材低效、评价低效等问题。要想解决这些问题,改变学生对教育学的错误认识,必须同时改变教学法、使用更好的教材、提高评价的水平和质量。     

教师行为研究述评

教师行为是教师素质的外化形式。狭义的教师行为仅指教师在教育教学中所采取的具体行动。本文对教师行为与学生行为的关系、教师培训对教师行为改变的影响、文化背景差异对教师行为的影响进行了探讨。在研究教师行为特征时采用问卷法、观察法和自然实验法。最后提出了四个有待进一步研究的问题。     

杭州富阳运动休闲产业品牌发展的实证研究

杭州富阳运动休闲产业已初具规模,通过调查分析表明:运动休闲产品制造企业规模以小型为主,民营资本占主导地位;产品种类齐全,运动休闲健身器材、运动休闲服装优势明显;开业时间主要集中在90年代;产业集群现象明显。名牌总数少,中高端品牌缺乏。在品牌战略上应选择区域发展战略、梯度品牌战略、品牌文化创新战略。     

浅谈数学思想的渗透

数学思想的渗透是数学教育成功的关键。这就要求数学教师了解“大纲”要求，把握教学方法，遵循认识规律，把握教学原则．有意识地培养学生自我提炼，揣摩数学思想方法的能力。
