关键词： Feder模型   高技术产业   溢出效应  

摘要： 本文将工业分为高技术产业和传统产业两个部门,应用Feder模型研究发现:高技术产业产出通过与传统工业部门的弹性关系而影响其增长,进而影响整个工业的增长。对我国的数据检验表明:高技术产业对我国工业的直接带动和溢出效应都很显著,直接带动率为18%,溢出效应为2.2%;高技术产业的平均要素边际产出较传统工业的平均要素边际产出高出21.9%。研究也表明,我国高技术产业对工业发展的作用存在着高带动高溢出、低带动高溢出和高带动低溢出三类地区。

关键词： 国际货物买卖   合同形式   《CISG》   《合同法》  

摘要： 国际货物买卖合同的形式是当事人意思表示一致的体现。由于经济发展和法律制度的变化,我国对国际货物买卖合同形式的规定由强制要求当事人采用书面形式变为尊重当事人的意志。但是我国对于《CISG》第11条所作的保留仍然存在,其与我国现行《合同法》关于国际货物买卖合同形式的规定相抵触。本文通过阐述国际货物买卖合同形式的作用以及国内立法和国际公约的相关规定,重点分析《CISG》与我国《合同法》在合同形式上的冲突,并针对我国目前国际货物贸易的发展现状,对该问题提出相关完善的建议。

摘要： About 100 countries have established regulatory limits for aflatoxin in food and feeds. Because these limits vary widely among regulating countries, the Codex Committee on Food Additives and Contaminants began work in 2004 to harmonize aflatoxin limits and sampling plans for aflatoxin in almonds, pistachios, hazelnuts, and Brazil nuts. Studies were developed to measure the uncertainty and distribution among replicated sample aflatoxin test results taken from aflatoxin-contaminated treenut lots. The uncertainty and distribution information is used to develop a model that can evaluate the performance (risk of misclassifying lots) of aflatoxin sampling plan designs for treenuts. Once the performance of aflatoxin sampling plans can be predicted, they can be designed to reduce the risks of misclassifying lots traded in either the domestic or export markets. A method was developed to evaluate the performance of sampling plans designed to detect aflatoxin in hazelnuts lots. Twenty hazelnut lots with varying levels of contamination were sampled according to an experimental protocol where 16 test samples were taken from each lot. The observed aflatoxin distribution among the 16 aflatoxin sample test results was compared to lognormal, compound gamma, and negative binomial distributions. The negative binomial distribution was selected to model aflatoxin distribution among sample test results because it gave acceptable fits to observed distributions among sample test results taken from a wide range of lot concentrations. Using the negative binomial distribution, computer models were developed to calculate operating characteristic curves for specific aflatoxin sampling plan designs. The effect of sample size and accept/reject limits on the chances of rejecting good lots (sellers'risk) and accepting bad lots (buyers' risk) was demonstrated for various sampling plan designs.

摘要： We propose a PAC-Bayes theorem for the sample-compression setting where each classifier is described by a compression subset of the training data and a message string of additional information. This setting, which is the appropriate one to describe many learning algorithms, strictly generalizes the usual data-independent setting where classifiers are represented only by data-independent message strings (or parameters taken from a continuous set). The proposed PAC-Bayes theorem for the sample-compression setting reduces to the PAC-Bayes theorem of Seeger (2002) and Langford (2005) when the compression subset of each classifier vanishes. For posteriors having all their weights on a single sample-compressed classifier, the general risk bound reduces to a bound similar to the tight sample-compression bound proposed in Laviolette et al. (2005). Finally, we extend our results to the case where each sample-compressed classifier of a data-dependent ensemble may abstain of predicting a class label.

摘要： The bacteriophage T4 DNA polymerase forms fluorescent complexes with DNA substrates labeled with 2-aminopurine (2AP) in the template strand;the fluorescence intensity depends on the position of 2AP. When preexonuclease complexes are formed, complexes at the crossroads between polymerase and exonuclease complexes, 2AP in the +1 position in the template strand is fully free of contacts with the adjacent bases as indicated by high fluorescence intensity and a long fluorescence lifetime of about 10.9 ns. Fluorescence intensity decreases for 2AP in the template strand when the primer end is transferred to the exonuclease active center to form exonuclease complexes, which indicates a change in DNA conformation;2AP can now interact with adjacent bases, which quenches fluorescence emission. Some polymerase-induced base unstacking for 2AP in the template strand in exonuclease complexes is observed but is restricted primarily to the n and +1 positions, which indicates that the DNA polymerase holds the template strand in a way that forces base unstacking only in a small region near the primer terminus. A hold on the template strand will help to maintain the correct alignment of the template and primer strands during proofreading. Acrylamide quenches 2AP fluorescence in preexonuclease and in exonuclease complexes formed with DNA labeled with 2AP in the template strand, which indicates that the template strand remains accessible to solvent in both complexes. These studies provide new information about the conformation of the template strand in exonuclease complexes that is not available from structural studies.
