汉字形旁类化研究

形音性质的汉字，在使用状态下，受上下文字形、字义的影响，出现大量的形旁类化字，对汉字系统的变化、汉字与它记录的词语的对应关系、汉字的写词显义功能等方面都产生了较大的影响。形旁类化字与假借字、区别字形式相同，而实质不同。讨论汉字形旁类化问题是汉字发展史研究的一项重要任务。     

Screening for hearing loss in early childhood programs

This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed.

Lucene相似度计算方法研究和改进

Lucene中的相似度计算可以让用户得到与查询词相似程度最高的文本,以及文本与查询词的相似程度,因此是Lucene搜索引擎的一个很重要的部分。最后的得分通过评分公式来实现,它的性能直接影响了评分结果,因此针对评分公式算法加以改进,改进后的Lucene相似度计算评分公式更准确地为用户提供所需要的信息。     

教学交往"对话"品性的迷失与回归

对话不仅是教学交往的主要形式和途径,它更构成了教学交往的重要品性和灵魂.然而,在现实的教学交往过程中,"对话"品性却在不知不觉中迷失了.文章指出这种教学交往"对话"品性的迷失主要表现为:教师把持了教学交往的主动权和话语权,民主、平等、尊重、信任、宽容和爱在教学交往中严重缺位,繁杂的训练和记诵取代了对课程内容(文本)的多元理解和解读.文章分析了其主要原因在于:师生对话意识的高度淡漠,教师对教育权威的深度误读,师生生存交往的典型缺失,哲学解释学思维的严重缺位.最后,文章认为,回归教学交往的"对话"品性必须做到:树立平等意识,做到真诚倾听;淡化权力观念,重视内在权威;优化师生交往,构建生存关系;"悬置"传统的教学认识方式,以哲学解释学的思维关照教学交往.     

中国文化背景下对丧失的理解与处理

丧失是人类生命历程中最为深重的情感,在不同的文化背景下,人们对丧失与哀伤有着不同的言说,每个个体对丧失的理解不同,就意味着对生命意义的理解不同,也意味着面对丧失与哀伤的方式不同。本文通过对几个有关丧失的个案,讨论了如何在中国文化容器下安放哀伤与哀悼,促进当事人的稳定化。     

Prenatal parenthood

In this article, we discuss the intuitive knowledge mothers have of their unborn baby. We propose a shift in focus from caregivers' merely providing information to first listening to pregnant mothers as they share their intuitive knowledge of their baby. This approach enables mothers and fathers or partners to know they are already parents to their unborn baby and empowers them to get in touch with their baby's presence and who he or she is during pregnancy. This intuitive knowledge may be a protective behavior that will enable mothers to keep babies safe during pregnancy.

上海市入境旅游市场时空分布格局及其演变研究

依据2001～2010年相关数据,采用季节强度指数、季节变化指数、地理集中指数、RCA指数等方法,对近10年来上海入境旅游客源市场时空演变进行统计分析。结果表明：在时间上,上海入境游客数量发展呈现波浪形递增趋势,年内变化幅度较小,高峰（旺季）主要是在4,5,9,10月,形成较明显的“M”形曲线;在空间上,客源地地理集中程度较低,分布较均衡;通过RCA指数的计算得出,上海市入境旅游16个吝源国中有11个处于极强竞争力状态。     

部分覆盖被动约束层阻尼板的动力特性分析

由薄板的基本方程出发,考虑粘弹性层与基板、约束层间的法向和切向相互作用力的影响,导出部分带状覆盖被动约束层阻尼（Passive Constrained Layer Damping,PCLD）板在两端简支另两端任意边界情况下的一阶常微分矩阵方程,方程的状态向量由4个独立的位移变量和内力变量组成,可方便地应用于位移和应力边界条件。同时,利用精细积分法和传递矩阵原理求解特征方程,计算了多种情况下PCLD板的固有频率和损耗因子。通过与参考文献结果相比,验证了本文方法的正确性。最后,分析了覆盖位置和覆盖率对结构减振特性的影响。
