Historically, agriculture education has been a dynamic and growing facet of career and technical education in the United States. Currently, however, public policy and support for agriculture education is negatively impacted by a national attitude that devalues agriculture education and perceives it as less desirable than a four-year college degree. This paper considers the history, scope, and current status of agriculture education in the context of increasing worldwide demand for agricultural products and rapidly changing technology.展开更多

As the law formulated in the forming period,Tort Law of the PRC has higher legal rank and wider regulation scope than former laws in this field. It balances public and private interests. It establishes unified regulations about third party liability of ISP in the field of basic law related to civil affairs. In application of Article 36 of Tort Law,it should be noticed that this article is liability component,and it defines only one form of infringement liability-contributory infringement. No classification of ISP is presented in this article.展开更多

OPVs of maize were cultivated and selected by different farmers in France and Italy for 2 generations. The third year, they were phenotypically evaluated for evolution, adaptation and level of diversity (estimated with Nei index) across evolution in a combined on farm and on station experimentation. The results showed that the varieties evolved and even adapted over 2 generations only (especially on maturity traits) but conserved their identity (no evolution of ear morphological traits). They all conserved their diversity, which demonstrated the pertinence of farmers’ selection (it is not a bottleneck). These results suggested that the genetically heterogeneous nature of OPVs is an asset for farmers because they can adapt these varieties to specific local conditions and production objectives. Therefore, farmer OPVs should receive more support through social and regulatory recognition, as well as further interest from research.展开更多
