探索对外汉语文化教学的有效途径

语言和文化的关系密不可分,语言教学离不开文化传授。在对外汉语教学中,应把文化背景知识教学寓于语言课教学和实践课教学之中。在课堂教学过程中注意运用对比的方法,防止“负迁移”作用。注意区分留学生所属的“文化圈”,有针对性地因材施教。采取灵活多样的教学手段,促进文化交流与融合。

辨析生态旅游内涵

生态旅游是一种新兴的旅游产品,国内外学者对生态旅游概念有不同的阐述,剖析各种界定,指出生态旅游的四个标准:是一种旅游方式;以自然为基础;以可持续发展为原则;以学习和教育为核心内容。在此基础上,讨论了生态旅游与绿色旅游、自然旅游、探险旅游和可持续发展旅游的区别和联系,揭示出生态旅游的本质内涵。

政府与私营企业间的劳资关系

我国私营企业劳资关系的失衡,是制约构建和谐社会的重要因素。在我国目前市场经济体制发育不成熟的情况下,优化私营企业的劳资关系,政府的作用不容忽视。科学界定政府在协调私营企业劳资关系的地位,把私营企业劳资矛盾控制在既有的社会秩序范围之内,才能保证社会的和谐发展。     

中国戏曲中的美——昆曲的艺术魅力及昆曲的传承与革新

以昆曲的艺术魅力为主线就昆曲的传承与革新问题提出几点思考。昆曲是我国一种古老的戏曲剧种,它的剧目丰富,曲调婉转,表演优美动人,是中国古典戏曲的代表。在“流行”已逐渐成为人们审美定势和思维习惯的现今社会,昆曲在中国传统文化轨道中将如何生存和健康地发展,是摆在戏曲界的一个问题。     

Effect of Rating Scales and Test Parts of Body on the Evaluation Results of Fabric-evoked Prickle

IntroductionThe studies of Schneider and Holcombe[1]and Liet al .[2]demonstrated that s mooth and light-weightwool fabrics were able to enhance fabrics in the market-place the sensations of coolness when worn in war m andhumid environments due to wool s hygroscopicity . Thisis the principle underlying the development of “coolwool”.However ,someti mes wool products are complainedof prickle . In the study of Wang et al .[3],it was foundthat the main shortcoming in ter ms of comfort for light…     

Sensor management based on fisher information gain

1 .INTRODUCTIONSensor management can be described as a systemor process that provides automatic or semi-auto-matic control of a group of sensors[1]. The basicobjective of sensor management is to select rightsensors to do the right service on the right targetat right ti me based on external measurements orcriteria[2]. A variety of techniques have been pro-posed or appliedtothe area of sensor management .One of the first articles to apply opti mization tech-nique to sensor management is by …     

A QUANTIFIER-ELIMINATION BASED HEURISTIC FOR AUTOMATICALLY GENERATING INDUCTIVE ASSERTIONS FOR PROGRAMS

A method using quantifier-elimination is proposed for automatically generating programinvariants/inductive assertions.Given a program,inductive assertions,hypothesized as parameterizedformulas in a theory,are associated with program locations.Parameters in inductive assertions arediscovered by generating constraints on parameters by ensuring that an inductive assertion is indeedpreserved by all execution paths leading to the associated location of the program.The method can beused to discover loop invariants-properties of variables that remain invariant at the entry of a loop.Theparameterized formula can be successively refined by considering execution paths one by one;heuristicscan be developed for determining the order in which the paths are considered.Initialization of programvariables as well as the precondition and postcondition,if available,can also be used to further refinethe hypothesized invariant.The method does not depend on the availability of the precondition andpostcondition of a program.Constraints on parameters generated in this way are solved for possiblevalues of parameters.If no solution is possible,this means that an invariant of the hypothesizedform is not likely to exist for the loop under the assumptions/approximations made to generate theassociated verification condition.Otherwise,if the parametric constraints are solvable,then undercertain conditions on methods for generating these constraints,the strongest possible invariant of thehypothesized form can be generated from most general solutions of the parametric constraints.Theapproach is illustrated using the logical languages of conjunction of polynomial equations as well asPresburger arithmetic for expressing assertions.     

《吾国吾民》与西方“中国形象”话语的互动

林语堂在《吾国与吾民》中建构的“中国形象”与西方“中国形象”话语谱系有着明显的联系与区别。针对西方“中国形象”话语的负面成分。例如“黄祸说“”以及中国妇女形象等问题，林语堂在建构自己的“中国形象”时作了修改；同时，林语堂也借鉴了西方“中国形象”的合理成分。这一借鉴隐含了现代性的观照。林语堂的“中国形象”建构策略为中西文化交流提供了很好的范倒。
