New Plant Variety Protection in Chinese Agriculture

New plant variety prevention is an important composition of strategy in China IPR and agriculture advantage, also the engine for promoting agriculture innovation, as for the challenge and the opportunity of accessing to WTO, efficiently using TBT to protect China new plant variety, and advantage S＆T innovation independently. China joined UPOV in 1994, and promulgates the protection statue of new plant variety. This paper analyzed the actuality and existing problems of new plant variety prevention in China agriculture, and the countermeasures to promote the development of new plant variety protection are brought forward.

Some alternative tests of forward exchange rates as predictors of future spot rates

The paper provides empirical analysis on the issue of forward premiums as predictors of future exchange depreciations. The need to specify an alternative to the null hypothesis, other than its complement is emphasized. Two such alternatives are considered: the random walk model and the possibility of excessive or insufficient exchange rate volatility to accord with the efficiency of exchange markets.     

Willingness to pay for pST-treated pork

The progress in porcine somatotropin (pST) application justified an assessment of consumer acceptance of pST-treated pork. A survey of the Atlanta metropolitan area, USA, collected information about consumer attitudes toward lean pork produced with biotechno-logically developed pST. A qualitative dependent variable model was used to identify socioeconomic consumer characteristics influencing the willingness to pay for lean pork. The model was modified to account for the selectivity bias of the sample data. Results indicate that frequent pork consumers were willing to pay more for lean pork produced using pST in contrast to respondents who frequently ate beef, were older, and had relatively high income. Probabilities associated with the willingness to pay a specific premium were calculated. In general, the average respondent was willing to pay an additional 18¢ per kg of lean pork produced using pST.     

星载合成孔径雷达数据压缩

星载遥微波成像雷达的观测区域广阔，图像分辨清度高。所以，星载遥感微波成像雷达具有数据率高、数据量大的特点。这就对遥感数据的传输和存储提出了较高的要求。本文提出采取数据压缩方法，在不降低测绘带宽和测绘精度条件下，降低遥感雷达数据率和数据量，从而降低对数据链和星上数据存储设备的要求。本文还对遥感雷达原始数据压缩和遥感雷达图像数据压缩优缺点进行了比较，提出了采用遥感原始数据压缩的建议。最后，对遥感雷达原
