机会主义知识产权诉讼行为及其法律控制——美国法的经验和启示

机会主义知识产权诉讼是利用信息优势和交易专用性资产等因素不正当地通过诉讼获得利益的行为,属于利用缺乏依据的独占性权利寻租的行为,包括将竞争对手排除出市场以及收取高额许可费用等。机会主义诉讼增加了知识产权制度运行的社会成本,扭曲了知识产权保护和交易关系。通过借鉴美国法律规定和司法实践,引入减少临时禁令的颁发和由败诉原告承担律师费等约束机制,并积极采用部分判决和改进确认不侵权之诉等激励机制,以期帮助恢复知识产权制度的利益平衡机制。     

寓教于乐对提高课堂教学质量的重要作用

全民娱乐甚至娱乐至死的社会风气俨然飘进了各类学校课堂,课堂成了演艺场,教师成了演员,学生成了看客,课堂貌似热热闹闹,实则空洞无物,教学质量每况愈下。文章作者针对上述现象发表一些看法,并就如何在新形势下切实提高课堂教学质量提出一些建议。

论我国种子企业科技创新主体的法律支持

种子企业作为现代农业发展的主力军,是种业科技创新的主体。传统的农业高等院校、科研院所为主体的种业科技创新体制无法适应现代种业科技创新和发展的要求。种业核心竞争力关键在于具有较强的自主创新能力,使科学技术和成果迅速而有效地转化为生产力。当前我国种子企业在科技创新上所发挥的作用太小,自主创新能力薄弱,主要受困于法律地位、人才、科研体制、经费等问题,要改革传统的创新模式,使种子企业真正成为科技创新的主体,必须从政策法规、财政金融、科研人才、知识产权以及协同创新等方面为种子企业的发展壮大提供法律支持。

Tree species composition,structure and utilisation in Maruzi Hills Forest Reserve in Uganda

The study investigated the tree species composition, vegetation structure and harvesting pattern to guide management of the Maruzi Hills Forest Reserve. Stratified random sampling was used to site six (100 m × 100 m) permanent sample plots in the woodland, bushland and grassland vegetation types identified in the reserve. Rényi diversity profiles indicated that bushland vegetation had a lower Shannon diversity index (H = 2.054) than grassland (H = 2.38) and woodland vegetation (H = 2.319). Grassland and woodland vegetation also had lower proportions of the dominant species (α_∞ = 1.15 and 1.66, respectively) than bushland vegetation (α_∞ = 3.25). However, the mean stem density of the woodland, bushland and grassland vegetation was 214 stems ha^?1, 191 stems ha^?1 and 114 stems ha^?1, respectively. Bray-Curtis and Jaccard ecological distance matrices showed that, although the three vegetation types shared some common species, the ecological distances were relatively high suggesting significant species composition variation between the vegetation types, particularly between the bushland and the other vegetation types. The species with the highest proportional abundance in the survey were Combretum molle (23%), Acacia hockii (17.7%), Combretum collinum (16.1%), Grewia mollis (6.5%) and Lannea barteri (6.5%). Diameter size-class distribution of woody perennials and tree stumps indicated higher frequencies of the smaller-diameter size classes. The stump records were indicative of charcoal burning and firewood collection as major causes of tree/shrub harvesting. The Maruzi Hills woodland conservation strategy should consider the differences in species composition between vegetation types if the highest number of species is to be conserved.     

The Economics of Horticultural Biotechnology

Abstract

Technological change has driven economic progress in agriculture and will continue to play a crucial role in die 21st century. The latest wave of technological change in agriculture is based on die ability to specifically modify crop genetics dirough recombinant DNA techniques. Biotech crop varieties have been adopted on a wide scale in some agronomic crops, but horticultural crops face hurdles for commercialization. Market barriers are blocking die production of biotech horticultural crops diat have already been developed. High costs for research, development and regulatory approval combined with the small acreages planted and the diversity of varieties limit die potential for profitable applications of biotechnology for many fruits and vegetables, tree fruits and nuts, and nursery and landscape crops. Like most technological changes in agriculture, die introduction of modern biotechnology has met with spirited political opposition from some quarters. Such opposition could discourage adoption of biotech products that are wanted by some consumers, can be profitable for growers and could reduce the environmental impacts of crop production.
