试论隐喻理论指导下的英语词汇教学

隐喻不仅是一种修辞手段,而且还是人们认识事物、思考问题、确立概念的一种思维方式,是一种非常重要的认知方式.基于这一理论,针对英语词汇的教学现状,阐述了如何将这一理论运用到英语词汇教学中,以更有效地培养和提高学生的隐喻能力,从而提升词汇学习的效率.     

云南省少数民族传统体育进入社区体育的可行性研究

民族传统体育是伴随着人类社会的发展而萌生的.云南省是中国少数民族的聚集地,也是少数民族传统体育开展最活跃的地域之一.社区是人类生活的主要区域,社会活动中的每一个成员都生活在一定的社区内,社会成员的大部分活动都是在社区进行的,把少数民族传统体育渗透到社区体育中,让它可以传承民族传统体育文化,增强道德修养,弘扬民族精神,促进全民的健身娱乐.     

运动对人格干预的元分析

运用文献资料法、逻辑分析法、数理统计法等研究运动对人格发展的影响,进而为学校体育课程改革、学生全面发展提供依据。在Web of Science、Pub Med数据库、中国知网和万方数据库中检索运动影响人格的研究文献,经过严格筛选最终纳入4篇文献,均采用卡特尔人格问卷测量运动对人格的影响。研究的总样本量为526人,通过Cochrane评估工具对所选文献质量和发表偏倚情况进行科学评估,所纳文献质量属于中上等水平。运用Review Manager 5.3软件对纳入数据进行meta分析,结果显示,运动对聪慧性、敢为性、乐趣性、恃强性、有恒性水平均有显著提升作用,运动能显著降低参与者的怀疑性水平。亚组分析结果显示:登山运动、健美操、三大球、游泳可以显著提高个体的乐群性。三大球、小球、田径、民传和游泳均能显著降低参与者的实验性,表明运动能使个体遵守社会规则和道德准则。登山、三大球、田径、民传和游泳能显著提高个体的稳定性水平。在忧虑性上,三大球、小球、田径、民传和游泳运动能显著降低个体的忧虑性水平。在有恒性上,登山、健美操、三大球、田径能显著提高参与者的有恒性。在独立性上,三大球、小球、田径、民传和...     

小波变换在信号奇异性检测中的应用

小波变换突破了传统傅里叶变换等信号处理方法的限制,在时域和频域上可同时对信号实现局部化处理,这更符合信号非平稳的变频带结构特征,因而在信号检测奇异性等方面具有广泛的应用价值。本文简要地介绍了小波应用在信号奇异性检测方面变换的基本原理,并通过仿真实验进行了验证。     

在华跨国公司的社会责任实践与强化问题探析

跨国公司的社会责任对自身的可持续发展及全球经济与贸易的增长都具有重要的意义。可部分进入中国市场的跨国公司却做出了忽略甚至缺失社会责任的事情。本文分析了这种现象的原因,并提出了若干促进在华跨国公司承担社会责任的措施。     

Teaching learning disabled students goal-implementation skills

Eight learning disabled (LD) junior high school students were taught goal-setting and self-regulatory skills in a resource room setting. The training program was designed to help students set realistic goals, develop plans to achieve these goals, monitor and evaluate their own behavior, and accept responsibility for the outcome of goal-directed activities. The goal-implementation strategy was effective in increasing some students' rates of assignment completion in the resource room and the regular classroom. Following the training program, students attributed success to effort; failure was attributed to effort, luck, and task difficulty.     

具有动态学习能力的分层进化粒子群优化算法

针对粒子群算法(PSO)在优化高维多极值问题时容易陷入局部极值的问题,结合分层进化与动态学习策略,提出一种具有动态学习能力的分层进化粒子群优化算法(DHEPSO).该算法首先根据粒子适应度值将粒子划分为不同层级,对不同层级粒子采取不同的进化策略,避免迭代后期种群多样性快速消失;然后根据粒子所属层级的不同动态调整粒子学习...     

收益分配公平目标下的教育结构调整

以社会经济地位指数(SEI)作为衡量收益分配是否公平的一个替代性指标,利用课题组的调查数据将不同类型教育形式对收益分配的影响进行实证分析的结果表明,我国社会成员收益的两极分化情况较为严重。解决这一问题需要调整我国现行的教育结构,即完善就业前培训制度,实行普通高中后职业教育;加强专科层次的职业教育;大力发展本科层次的职业教育,试点更高层次的职业教育。     

Genomic diversity and post-admixture adaptation in the Uyghurs

Population admixture results in genome-wide combinations of genetic variants derived from different ancestral populations of distinct ancestry, thus providing a unique opportunity for understanding the genetic determinants of phenotypic variation in humans. Here, we used whole-genome sequencing of 92 individuals with high coverage (30–60×) to systematically investigate genomic diversity in the Uyghurs living in Xinjiang, China (XJU), an admixed population of both European-like and East-Asian-like ancestry. The XJU population shows greater genetic diversity, especially a higher proportion of rare variants, compared with their ancestral source populations, corresponding to greater phenotypic diversity of XJU. Admixture-induced functional variants in EDAR were associated with the diversity of facial morphology in XJU. Interestingly, the interaction of functional variants between SLC24A5 and OCA2 likely influences the diversity of skin pigmentation. Notably, selection has seemingly been relaxed or canceled in several genes with significantly biased ancestry, such as HERC2–OCA2. Moreover, signatures of post-admixture adaptation in XJU were identified, including genes related to metabolism (e.g. CYP2D6), digestion (e.g. COL11A1), olfactory perception (e.g. ANO2) and immunity (e.g. HLA). Our results demonstrated population admixture as a driving force, locally or globally, in shaping human genetic and phenotypic diversity as well as in adaptive evolution.     

Goal setting and personal responsibility training for LD adolescents

A training program designed to teach Learning Disabled junior high school students to set realistic achievement goals, to expend effort to reach the goals, and to accept personal responsibility for achievement outcomes was conducted with 61 LD adolescents attending four junior high schools. Students were randomly assigned to an experimental or control group. Goal setting strategies and effort attribution training were introduced for a six-week period. Pre- to posttesting indicated that the experimental group learned to set realistic goals and to attribute achievement outcomes to the amount of personal effort expended.
