高职英语教学文化正迁移与语用能力的培养

第二语言学习涉及第二文化学习,因此第二语言学习也是一个文化移入的过程。高职英语教育的目标是使学生具备一定的英语交际能力,而目前高职学生在英语交际能力方面存在英语基础薄弱,西方文化知识匮乏等问题。试图通过探讨文化迁移这一造成语用失误的主要因素,从外语教学的角度归纳了三点培养学习者语用能力的启示：利用文化导向型英语教学模式,促进文化正迁移;设计跨文化交际教学内容,实现母语文化正迁移;培养教师本身的语用能力。     

GDF11 controls the timing of progenitor cell competence in developing retina

The orderly generation of cell types in the developing retina is thought to be regulated by changes in the competence of multipotent progenitors. Here, we show that a secreted factor, growth and differentiation factor 11 (GDF11), controls the numbers of retinal ganglion cells (RGCs), as well as amacrine and photoreceptor cells, that form during development. GDF11 does not affect proliferation of progenitors-a major mode of GDF11 action in other tissues-but instead controls duration of expression of Math5, a gene that confers competence for RGC genesis, in progenitor cells. Thus, GDF11 governs the temporal windows during which multipotent progenitors retain competence to produce distinct neural progeny.     

Ocean energy: forms and prospects

The nature and distribution of power sources of the sea other than petroleum are discussed, along with possible entrées for their use. Waves, tides, currents, and salinity and temperature gradients all have the potential to contribute useful power. Submarine geothermal sources, salt domes, ice, and other marine-associated concentrations may be more important. There are opportunities to employ these marine power resources directly rather than for contributions to power grids or power-intensive products. Ancillary employment of the seawater as a coolant and of the sediments below the seabed for the disposal of nuclear wastes may be even more important uses than employment of the power that the sea contains.     

Evolution in the social brain

The evolution of unusually large brains in some groups of animals, notably primates, has long been a puzzle. Although early explanations tended to emphasize the brain's role in sensory or technical competence (foraging skills, innovations, and way-finding), the balance of evidence now clearly favors the suggestion that it was the computational demands of living in large, complex societies that selected for large brains. However, recent analyses suggest that it may have been the particular demands of the more intense forms of pairbonding that was the critical factor that triggered this evolutionary development. This may explain why primate sociality seems to be so different from that found in most other birds and mammals: Primate sociality is based on bonded relationships of a kind that are found only in pairbonds in other taxa.     

Photon number squeezed States in semiconductor lasers

Electromagnetic fields, with the noise on one quadrature component reduced to below the quantum mechanical zero-point fluctuation level and the noise on the other quadrature component enhanced to above it, are currently of great interest in quantum optics because of their potential applications to various precision measurements. Such squeezed states of light are usually produced by imposing nonlinear unitary evolution on coherent (or vacuum) states. On the other hand, squeezed states with reduced photon number noise and enhanced phase noise are generated directly by a constant current-driven semiconductor laser. This is the simplest scheme for the generation of nonclassical light, and so far it has yielded the largest quantum noise reduction. The mutual coupling between a lasing junction and an external electrical circuit provides opportunities for exploring the macroscopic and microscopic quantum effects in open systems.     

Integration of molecular genetic technology with quantitative genetic technology for maximizing the speed of genetic improvement

To date,most genetic progress for quantita-tive traits in livestock has been made by selec-tion on phenotype or on estimates of breedingvalues(BBV)derived from phenotype,withoutknowledge of the number of genes that affect thetrait or the effects of each gene.In this quantita-tive genetic approach to genetic improvement,the genetic architecture of traits of interest hasessentially been treated as a‘black box’.De-spite this,the substantial rates of genetic im-provement that have been and continue to be a-chie...

英语教学翻译与翻译教学

英语教学任务和目标是在不同阶段培养相应的语言能力和交际能力,其有机组成部分包括教学翻译与翻译教学,这是两种概念不同,目的相异但又相互联系的教学设计类型。本文尝试由语言教学理论和语言教学角度探讨二者之间的关系,认为二者在概念和目的上不容混淆,但二者教学上存在着相互联系。     

Protein kinase C and regulation of the local competence of Xenopus ectoderm

The limited competence of embryonic tissue to respond to an inductive signal has an essential, regulatory function in embryonic induction. The molecular basis for the competence of Xenopus ectoderm to differentiate into neural tissue was investigated. Dorsal mesoderm or 12-O-tetradecanoyl phorbol-13-acetate (TPA) caused in vivo activation of protein kinase C (PKC) and neural differentiation mainly in dorsal ectoderm and to a lesser extent in ventral ectoderm. These data correlate with the observations that PKC preparations from dorsal and ventral ectoderm differ, the dorsal PKC preparation being more susceptible to activation by TPA and diolein than is the ventral PKC preparation. Monoclonal antibodies against the bovine PKC alpha plus beta or gamma isozymes immunostained dorsal and ventral ectoderm, respectively, which suggests different localizations of PKC isozymes. These results suggest that PKC participates in the establishment of embryonic competence.     

Mating in bighorn sheep: multiple creative male strategies

Rocky Mountain bighorn rams obtained copulations by defending single estrous ewes (tending), fighting tending rams for temporary access to defended ewes (coursing), or moving and holding ewes away from other rams beyond the periphery of a traditional tending area (blocking). Coursing and blocking illustrate a feature of many male alternative mating strategies: the ability of males regularly to create mating opportunities.

在对大学生就业能力文献研究分析的基础上,进一步阐明了提升高校毕业生就业能力的重要性,创建包括基本工作能力、专业能力和应聘能力三层次九维度的就业能力结构模型,并围绕该模型,引用高校人才培养供应链管理理念,从政府、企业、高校、学生4个方面提出了政府要加强促进就业的政策调控;企业要积极为高校毕业生创造就业机会;高校要创新人才培养模式,加强毕业生就业指导工作;毕业生自身定位要准确,培养良好的人格品质等对策建议。     

依托口译技能的跨文化交际能力培养模式及其效果

提高学生的跨文化交际能力可以通过显性路径和隐性路径两种方式.根据口译课程的特点,在口译教学中运用隐性教学方式将跨文化教学内容融入到口译各技能的训练之中是比较科学合理的做法.一项对比教学实验的结果表明,依托口译技能的跨文化交际能力培养模式对提高学生的跨文化敏感度整体水平没有显著促进作用,但是对差异认同感有显著积极影响;实验结果同时表明此教学模式能够显著提高学生的跨文化交际能力测试成绩.相关分析和回归分析结果表明,学生的综合跨文化敏感度和除了差异认同感的其他四个维度对学生的跨文化交际能力测试成绩没有产生显著影响,这说明该教学模式产生了一定的积极效果但还需在教学实践中不断修正以更全面和切实地提高学生的跨文化交际能力.

Working women scientists and engineers

About 80 percent of women trained in science or engineering are in the labor force, but many are employed outside of their fields. Most who withdraw from the labor force do so temporarily, and about half do not take a career break even when they have small children. Factors affecting labor force participation are student status, highest degree level, parental status and age of children, and field of degree. Employment opportunities are restricted in some fields, and women have higher unemployment rates and lower earnings than men. Some policy changes would improve opportunities for women, and better data are needed to monitor their participation in science and technology.     

企业会计人员职业胜任能力评价指标体系构建

伴随经济全球化进程加快和企业间竞争加剧,企业提高了对会计人员职业胜任能力的要求,所以构建适应企业要求的会计人员职业胜任能力评价指标体系势在必行。通过对国内外职业胜任能力评价研究现状分析发现,会计人员继续教育阶段能力评价的缺失是造成我国当前能力评价体系不完整的主要原因,由此构建了包括继续教育阶段以个性特征为首要指标的全面能力评价指标体系。
