关键词： 认可检验员   商品检验   贸易经济  

摘要： 认可检验员是商检机构组织外部技术力量对进出口商品进行检验的一种检验形式,同时也是充分依靠生产、供货单位的检验力量,落实出口商品出厂(仓)前检验工作的集中体现,是把商检工作从原来的检验型向监督管理型转移的内容之一。事实证明,认可检验员有利于保证出口商品质量。 陶瓷是汕头地区传统大宗出口商品,而且是地方创汇拳头产品,规格品种繁多,花色琳琅满目,产品远销欧美等国家和地区,在国际市场上具有一定的竞争力。但是由于出口陶瓷具有货期紧、时间短等特点。

关键词： 合同   合同形式   不要式  

摘要： 此文对我国合同形式的立法、实践和市场经济对合同形式要求的演变作了简单介绍。在此基础上，从合同本质、市场经济、国际公约、ＥＤＩ技术等方面论述了我国应当在立法上确立合同形式的不要式原则，认为这是合同自由的重要体现；如果放任目前在合同实践中出现的任意对合同形式、成立程序上进行限制的现象。

摘要： Ste5 is essential for the yeast mating pheromone response pathway and is thought to function as a scaffold that organizes the componentsof the mitogen-activated protein kinase (MAF K) cascade. A new method was developed to isolate missense mutations in Ste5 that differentially affect the ability of Ste5 tointeract with either of two MAPK cascade constituents, the MEKK (Stell) and the MEK (Ste7). Mutations that affect association with Ste7 or with Stell delineate discreteregions of Ste5 that are critical for each interaction. Ceimmunoprecipitationanalysis, examining the bindingin vitro of Ste5 to Stell, Ste7, Ste4 (G protein ,B subunit), and Fus3 (MAF K),confirmed that each mutation specifically affects theinteraction of Ste5 with only oneprotein. Whenexpressed in a ste5A cell, mutant Ste5 proteins that are defective in their ability to interact with either Stell or Ste7 result in a markedly reduced mating proficiency. One mutation that clearly weakened (but did not eliminate) interaction of Ste5with Ste7permitted mating at wild-type efficiency,indicating that anefficacioussignal is generated even whenSte5 associates with only a small fraction of (or only transiently with) Ste7. Ste5 mutants defective in association with Stell or Ste7 showed strong interallelic complementation when ceex- pressed, suggesting that the functional formof Ste5 in vivo is an oligomer.

摘要： This study explored whether an identity-matching-based stimulus equivalence procedure could be used to teach vowel and consonant stimulus classes to 2 adolescent females with moderate mental retardation. Delayed match-to-sample trials presented a compound sam- ple stimulus consisting of printed letters and a spoken word ( vowel or consonant ). The correct comparison stimulus matched only one of the letters in the compound sample. Subsequently, test trials assessed whether arbitrary relations had formed among the individual stimuli from each compound sample and whether stimuli from different compound samples had merged into larger stimulus classes. Both participants acquired ve-member classes of vowel and consonant stimuli, which subsequently generalized to vocal classication and to identication in the context of four-letter words. Follow-up tests showed that the generalized performances remained intact after 6 weeks. These procedures suggest an economical approach to stimulus class development.
