论著作权法中作者的收回权

目前许多国家知识产权法都规定作者享有收回权。收回权的客体是已经发表作品的使用权,其行使将对作品使用权人产生较大影响。为防止作者滥用这一权利,相关国家的法律均设置了较为严格的条件。收回权与发表权和修改权之间虽存在一定的联系,但有着本质上的区别。收回权在我国著作人身权体系中具有独立制度价值,应对其提供相应的法律保护。

Perceptions of the risks and benefits of genetically-modified foods and their influence on willingness to consume

There has been debate in the literature as to whether: (1) the risks and benefits of genetically-modified (GM) food and agriculture are considered and determined by individuals separately or whether they are jointly determined by attitudes; (2) consumer acceptance is determined by individuals weighing up their risk and benefit perceptions in a rational, even-handed manner, or if benefit perceptions are more important than risk perceptions, and (3) certain types of risk and benefit are more important than others. Against this background, this paper assesses the categories of risks and benefits and their relative importance in determining willingness to consume. A survey was carried out to collect data on the categories of risks and benefits in the US, UK and France, and the relative importance of selected perceived risk and benefit dimensions was estimated. The findings show: risk and benefit perceptions are negatively correlated, but not perfectly and, given that regressions we performed support the proposition that benefits are more important than risks in determining willingness to consume, a strong case can be made for measuring risks and benefits separately. Almost 2/3 of consumers perceive medium to high potential benefits from GM, though the proportion is slightly lower in the UK and down to 40% in France. Nevertheless, this suggests a much higher level of support for the technology than is normally assumed. From the study, benefits are more important for consumers' willingness to consume than perceived risks, and slightly more interviewees scored above than below the mean on willingness to consume GM food.     

Environmental issue management: towards a multi‐level theory of environmental management competence

The continuity and profitability of business firms are under constant threat from environmental issues – forthcoming developments in the environmental domain or involving environmental stakeholders that are likely to have an important impact on the ability of the enterprise to meet its objectives. Managers must forge responses to such issues, but must they respond in an ad hoc fashion to every issue or can they develop more coherent environmental management competences? Empirical evidence was collected from a case study of the environmental issue management practices of Unilever, one of the largest food and personal care companies in the world. This company's approach to dealing with the issue of genetically modified ingredients reveals that issue managers face a complex level‐of‐analysis problem when confronting environmental issues: how to translate individual‐level knowledge into organization‐level outcomes? The theory developed here suggests that once firms learn how to span this chasm, they are able not only to address discrete environmental issues, but also to build competitive environmental advantages through the development of integrative organizational competences.

WTO体制下的TBT-SPS规则修改与前景预测

技术性贸易壁垒作为非关税壁垒中最为隐蔽的一种阻碍国际自由贸易的障碍,与其他传统手段相比往往使出口国更难应付和适应。随着国际贸易的发展和贸易自由化程度的提高,各国实行动植物检疫制度对贸易的影响越来越大,动植物检疫已经成为一种隐蔽性很强的技术壁垒措施。文章通过明确TBT和SPS协议的内涵,回顾它们的形成、修改过程并联系WTO实例对这两个协议的前景做出预测。

Product attributes and consumer acceptance of nutritionally enhanced genetically modified foods

Using data from a national survey, this study analyses US consumers’ acceptance of genetically modified foods that provide additional nutritional benefits. Using an ordered probit model, this study examines the relation between the willingness to consume genetically modified foods and consumers’ economic, demographic and value attributes. Empirical results suggest that despite having some reservations, especially about the use of biotechnology in animals, American consumers are not decidedly opposed to food biotechnology. Consumers’ economic and demographic variables are only weakly related to their acceptance of food biotechnology, especially when technology involves plant‐to‐plant DNA transfer. However, public trust and confidence in various private and public institutions are significantly related to their acceptance of food biotechnology. Overall, consumer acceptance of bioengineered foods is driven primarily by public perceptions of risks, benefits and safety of these food products.
