发达国家农业知识产权服务体系对我国的启示

在新形势下,建立和运行我国农业知识产权服务体系是当前的一项紧迫任务。通过梳理美国、日本和韩国农业知识产权服务业培育的做法,汲取其农业知识产权服务体系建设的有益经验,结合我国实际,提出我国农业知识产权服务体系发展对策：健全农业知识产权服务制度体系;建立农业知识产权服务业部门协作机制;完善农业知识产权公共服务体系;培育农业知识产权服务市场;重视农业知识产权转化应用;发挥农业知识产权服务“第三方组织”的作用。     

应用程序商店著作权侵权问题研究

针对应用程序商店存在的著作权侵权问题,分析并对比安卓与苹果应用程序商店的商业经营模式,认为两者具有不同的法律属性:苹果应用程序商店更接近于网络交易平台,负有审查义务且不适用"避风港"原则,只能构成直接侵权;而安卓应用程序商店属于信息储存空间类的网络服务提供商,不负有审查义务且适用"避风港"原则,直接侵权行为与间接侵权行为并存;提出对应用版权的保护不仅要达到版权人、应用程序商店与公众三方之间的利益平衡,更要注重不同性质的应用程序商店在版权保护中所扮演的角色及应承担的责任.     

博物馆文化资源开发的产权确认与授权思考

中国博物馆文化资源丰富,博物馆文化资源的产业开发虽然与境外国家博物馆文化资源的产业开发有较大差距,但已呈现蒸蒸日上的发展态势.馆藏文化资源的“活化”利用在文化创意产品的开发中,发挥着愈来愈重要的作用.博物馆文化资源开发的实质,在于产权交易,通过藏品的产权确认、物权处置、版权授权等交易流程呈现出来.博物馆藏品原件的物权归属和藏品版权的确认,使博物馆在文化创意产业发展中可通过版权授权制度,为博物馆藏品的“保护与利用”寻找新的发展路径,推动博物馆文化创意产业迅速发展.     

基于期权合约的供应链协同决策研究

本文在市场需求和价格不稳定的双重背景下,研究以风险规避为目的的供应商如何在供应链管理中运用期权合约实现利润最大化的途径问题。供应商通过在二级供应链中引入实物期权,在购买方需求不确定时可以将其引致的风险转移向供应方,而供应方的风险通过来自期权合约的额外收益在最大程度上被平衡。本文在分析考虑期权因素的决策模型中,研究市场需求以随机分布状态变化时,构建具有期权合约的最优利润最大化模型问题。数值算例验证了期权合约策略模型的可行性。本研究在一定程度上完善了供应链中期权合约的风险规避模型,为供应链企业风险管理的决策依据提供了有用的实践参考价值。     

Valuation of contingent claims with stochastic interest rate and mortality driven by Lévy processes

Abstract

In this paper, we consider a model with stochastic interest rate and stochastic mortality, which is driven by a Lévy process. Under the assumption that the stochastic mortality and interest rate are dependent, we discuss the valuation of life insurance contracts. Employing the method of change of measure together with the Bayes’ rule, we present the pricing formulas in closed form for the survival and death benefit models. Finally, numerical experiments illustrate the effects of some parameters.     

A kind of stochastic recursive Zero-Sum differential game problem with double obstacles constraint

Abstract

This paper concerns a class of stochastic recursive zero-sum differential game problem with recursive utility related to a backward stochastic differential equation (BSDE) with double obstacles. A sufficient condition is provided to obtain the saddle-point strategy under some assumptions. In virtue of the corresponding relationship of doubly reflected BSDE and mixed game problem, a stochastic linear recursive mixed differential game problem is studied to apply our theoretical result, and here the explicit saddle-point strategy as well as the saddle-point stopping time for the mixed game problem are obtained. Besides, a numeral example is also given to demonstrate the result by virtue of partial differential equations (PDEs) computation method.     

“特别301条款”运行机制研究

通过对美国贸易法“特别301条款”的历史演变和运行机制的研究，分析其与WTO规则之间相互配合，同时又为自己保留“法外”空间的现状，判断其未来将如何在WTO规则对其有利时，作为监督与审查他国的工具；反之，则越过WTO规则以自己的标准提出苛刻要求。对此，中国应加快自身发展，增强实力，才能改变被动局面。     

《1844年经济学哲学手稿》视域中的交往与共产主义

在黑格尔将特殊性原则主导的市民社会趋向作为普遍性与特殊性伦理统一的国家看作必然性的地方,《论犹太人问题》时期的马克思则看到了"国家不能挽救市民社会于自身之中",并且"国家的秘密在市民社会之中"。因此,马克思开始从市民社会内部探索自由的障碍以及自由的实现问题。《1844年经济学哲学手稿》时期的马克思将自由的障碍以及自由的实现表述为劳动异化、私有财产异化以及造成这一异化的深层根源的交往异化和"私有财产即人的自我异化"积极扬弃的共产主义。     

YOUR SECOND LIFE?

This article examines the performativity of intellectual property in digital gaming environments, with a focus on Massively Multi-Player On Line Games (MMOGs). The analysis centers on the creation and management of goodwill, an intangible asset of considerable value to corporations based on affective bonds between consumers, corporations, and their commodities in the marketplace. Most critical analyses of intellectual property consider neither the centrality of goodwill to corporate management of their intellectual properties in digital environments, nor the significance of the legal conditions that structure activity in such contexts. We develop a theoretical framework based on cultures of circulation involving network sociality, circuits of interactivity and the extensibility of the computer/user interface. This enables us to better understand shifting relations of power and reciprocity between corporations and consumers in digital gaming contexts, where the division between player-consumption and player-production is increasingly blurred. Technological capacities for consumers to become producers of gaming content changes the terrain upon which conflicts between corporations and consumers about intellectual property are negotiated and enhances the value of goodwill. An examination of Linden Lab's Second Life – one of the fastest growing MMOGs and the first to affirm players’ intellectual property rights in their digital creations – provides an illustration of both the limits and possibilities afforded by goodwill as a form of emerging governance in game worlds.     

Codependent Cycles of Chinese Inflation

A test and decomposition of the codependent cycles of the consumer price index (CPI), agricultural producer price index (APPI) and M2 reveals that the sharp cyclical fluctuations in agricultural producer prices largely stem from the grain price fluctuations induced by factors such as land enclosure and the impact on APP of the abrupt changes in pork prices and other factors. Therefore, changing the current policy of grain purchasing price subsidies to one of subsidies to grain production and sales will reduce the impact of grain prices and other factors on APP and inflation. The weak cyclic codependence among APP, CPI and M2, along with the strong cyclic codependence between M2 and CPI, has given rise to a “shuttle-shaped” intersection of cyclic elements. This indicates that China’s monetary policy goal has been alternating between curbing inflation and stimulating growth. When the APP cycle is basically stable, China can implement a moderately easing monetary policy to stimulate economic growth, but this must be based on a 1.5 or so margin of increase in the codependent cycle components of M2. When APP rises sharply or is in the rising phase of cycle elements, China should emphasize APP control, and should delay the moderately easing monetary policy till the APP cycle becomes stable or is in the downlink phase.
