使用市场营销学、法学、经济学、语言学与心理学的方法对品牌功能进行综合研究,认为高强品牌具有保障产品质量、降低消费者搜寻成本并能满足消费者心理需求等功能,高强品牌同时还可以使品牌所有者通过各种途径来扩大其经济利益。通过对高强品牌的功能研究发现不仅仿冒行为会损害高强品牌的价值,而且其他与高强品牌相联系的行为均会造成高强品牌价值的贬损。因此,美国法律也随着品牌功能的不断变化而逐步扩大其保护的范围(尤其是对高强品牌的保护),以适应品牌发展的需求。 相似文献

解决“三农”问题的重要途径在于发展农村市场,广大农民是农村市场最重要的主体。然而,农户作为农村集体经济组织的成员——农村承包经营户,依照我国现行《民法通则》、《农村土地承包法》等规定,是一种民事法律关系的主体,享有民事权利和承担民事义务。在我国市场经济条件下的商事法律中,关于农民、农户在农村市场的商事经营主体资格的制度设计比较缺乏,从而在一定程度上制约了农民的市场行为。为了充分调动广大农民积极性,更好地建设和发展农村市场,有必要完善农户商事经营主体资格的法律制度。 相似文献

Social movements have been viewed as vehicles through which the concerns of poor and marginalized groups are given greater visibility within civil society, lauded for being the means to achieve local empowerment and citizen activism, and seen as essential in holding the state to account and constituting a grassroots mechanism for promoting democracy. However, within development studies little attention has been paid to understanding how social movements can affect trajectories of development and rural livelihood in given spaces, and how these effects are related to movements’ internal dynamics and their interaction with the broader environment within which they operate. This paper addresses this theme for the case of social movements protesting contemporary forms of mining investment in Latin America. On the basis of cases from Peru and Ecuador, the paper argues that the presence and nature of social movements has significant influences both on forms taken by extractive industries (in this case mining) and on the effects of this extraction on rural livelihoods. In this sense, one can usefully talk about rural development as being co-produced by movements, mining companies, and other actors, in particular the state. The terms of this co-production, however, vary greatly among different locations, reflecting the distinct geographies of social mobilization and of mineral investment, as well as the varying power relationships among the different actors involved. 相似文献

Relative Guarantees 总被引:1,自引:0,他引:1
Snorre Lindset 《The GENEVA Papers on Risk and Insurance - Theory》2004,29(2):187-209
Many real-world financial contracts have some sort of minimum rate of return guarantee included. One class of these guarantees is so-called relative guarantees, i.e., guarantees where the minimum guaranteed rate of return is given as a function of the stochastic return on a reference portfolio. These guarantees are the topic of this paper. We analyse a wide range of different functional specifications for the minimum guaranteed rate of return, hereunder both so-called maturity and multi-period guarantees. Several closed form solutions are presented. 相似文献

The community of statisticians and statistics educators should take responsibility for the evaluation and improvement of software quality from the perspective of education. The paper will develop a perspective, an ideal system of requirements to critically evaluate existing software and to produce future software more adequate both for learning and doing statistics in introductory courses. Different kinds of tools and microworlds are needed. After discussing general requirements for such programs, a prototypical ideal software system will be presented in detail. It will be illustrated how such a system could be used to construct learning environments and to support elementary data analysis with exploratory working style. 相似文献

The paper analysesthe reforms of the Italian mandatory pension scheme for employeeslegislated in the 1990s. To assess the effects of the reforms,a microsimulation model calibrated on cross-section data is developed.The model is aimed at estimating the average income of a memberof a cohort, as well as the average per capita income of allindividuals alive in a given year. The long-run effects of thereform are analysed, comparing the characteristics of alternativefinancing schemes. A substantial improvement of the equity aswell as the long-run sustainability of the Italian public pensionschemes emerges. However, the dreary demographic scenario callsfor further tightening of eligibility rules sometime in the nextdecades if long-run sustainability of public debt is to be achieved.On the basis of sensitivity analysis, some changes aimed at hedgingthe system against unexpected shocks are suggested. 相似文献

This article reviews the law regarding Title VII employment discrimination protection from religious discrimination. The issues surrounding the principal legal protection in this regard are explored in the context of a recent controversial case in which an author, Forrest Mims, was not hired as a regular contributor forScientific American magazine, ostensibly because of his belief in the theory of creation over the theory of evolution. The definition of what constitutes a protected religious belief or practice is seen to have expanded over time. However, a belief in creationism is not necessarily seen as being tantamount to a religious belief under present legal interpretation of Title VII. The implications of this finding for future needed Title VII revision are discussed. 相似文献
