产业集群中社会资本创新绩效研究

本文分析了集群中社会资本的形成机制、演变特征及其对集群创新绩效的影响.作者认为,集群中社会资本的形成机制及演化路径是决定集群创新绩效的关键因素,而要保持集群持续的创新优势.就必须转变社会资本积累的传统方式,使社会资本积累突破既有的传统文化和地缘关系的限制.     

论域名的权利属性

域名应属于知识产权的范围,是一种与商标、专利并列的新型的知识产权,因为其是创造性的智力成果,完全具备了知识产权的三大基本特征,即地域性、专有性、时间性。域名权作为一种新的知识产权,其权利内容应该包括人身权、专有使用权、标识权、转让权、许可权。

Nonnegative Definiteness of the Sample Autocovariance Function

Various textbooks on time series analysis assert that the usual version of the sample autocovariance function (1) is nonnegative definite. Two simple proofs of this result are presented.     

Asymptotic properties of the bootstrap unit root test statistic under possibly infinite variance

ABSTRACT

In this article, the unit root test for the AR(1) model is discussed, under the condition that the innovations of the model are in the domain of attraction of the normal law with possibly infinite variances. By using residual bootstrap with sample size m < n (n being the size of the original sample), we bootstrap the least-squares estimator of the autoregressive parameter. Under some mild assumptions, we prove that the null distribution of the unit root test statistic based on the least-square estimator of the autoregressive parameter can be approximated by using residual bootstrap.     

Borrowing strength from past data in small domain prediction by kalman filtering - a case

Point and interval estimators for small domains based exclusively on current and domain specific sample observations are generally ineffective because of inadequate sample-sizes. So, borrowing strength from sample values for analogous domains and simultaneously from all relevant past and auxiliary data is useful in deriving improved small domain statistics. Postulating for simplicity a linear regression model with a single covariate and a zero intercept but a time-specific domain-invariant slope we start with “synthetic” generalized regression predictors for the domain totals. These borrow across only domains. For further improvements a simple autoregressive model is postulated for the slope parameters. Employing Kalman filtering the previous predictors are revised to borrow supplementary strength across time. As drastic simplifying assumptions are needed in such predictions the efficacy of the procedure is examined through an empirical exercise using live data as well as simulations. The numerical findings turn out encouraging.     

序数表属性量级的双向性

属性值语素与属性域语素互相融合,是原型区别词的生成机制。序数表达属性量级具有明显的双向性：采用升序,数字越大,量级越高;采用降序,数字越大,量级越低。这在交际中常常造成含混与误解。序数表量级的双向性源于数词的中性色彩。最小正整数＂一＂在汉文化中具有无与伦比的重要地位,用来表示大量级是很自然的事情,采用降序是汉文化的优选原则。     

报纸版面与新闻网站首页设计之比较

报纸与新闻网站虽然属于两种新闻媒体,但由于它们使用的媒介有相同之处,因此在编排方式上就有共同规律可言。本文从版面空间、强势、板块与专栏、标题、图片、布局结构、版面的美化等七个方面对二者进行了比较,既发现了它们的共同点,又更清楚地认识了二者的不同,从而可以为提高新闻网站的设计水平提供更多的依据。     

试论建构我国家庭教育评价体系的紧迫性

现代社会中家庭教育的价值日益彰显,但现实中我国家庭教育往往沦为经验式活动,缺乏科学的指导体系,建构家庭教育评价体系加强对其科学指导也就更显迫切性,而家庭教育逐渐由私人领域转向公共领域的趋势也为建构家庭教育评价体系提供了可能性和可行性。     

OUT OF SIGHT AND OUT OF MIND

Based on E.P. Thompson's insistence that cultural hegemony involves the creation of blinkers that open up certain venues of sight while closing down others, this essay relies on the faculty of seeing (or not-seeing) to suggest a critique of the critique of intellectual property rights. In the current climate of increasing intellectual property expansionism, the public domain has emerged the positive other, a shield against the missiles launched by the blitz-krieg inclined copyright holders, even perhaps a benevolent Dr Jekyll to ward off Mr Hyde's hyper-aggression. I will argue that two powerful rhetorical devices have become commonplace in the critique against the current intellectual property system and in defense of the value of the public domain: creativity and free/dom (or the ideas of free and freedom), and that these, far from being simple and universal categories, in fact are constructions that need to be further problematized and discussed. The ongoing copyright wars have resulted in a polarization of debate and ways of thinking that sometimes hide the complexities of the problem at hand. Instead, a more constructive way to approach the private/public matrix is to envision them not as static opposites, but as constituents of a field in constant flux. As we consider the public domain, must we also deal with intellectual property rights, or rather with flows of ownership between spheres that we sometimes define as private, sometimes as public.
