论马克思的产权理论

产权是财产主体对财产所拥有的排他性、归属性的关系和权利,体现了人与人之间的经济关系或经济权利.产权由所有制决定,受到一定的法律保护,体现了一定的历史范畴.     

90年代后期中越经贸关系及其发展前景

中国同越南之间的经贸联系自古已经开始 ,两国的民间贸易往来十分频繁 ,但受各种因素的影响 ,两国的官方贸易发展缓慢。 1991年中越关系正常化后 ,双方的贸易关系开始迅速发展 ,正规贸易额基本呈直线上升趋势 ,但客观来讲 ,仍未达到应有的水平 ,特别是与两国日益强化的政治关系相比较为滞后。如何改变这种状况 ,一直是两国政府十分关注的议题。目前 ,随着双方政治关系的不断发展 ,加强经贸领域的合作已逐步提到议事日程。其实 ,中越双方在经贸领域有着十分有利的合作条件 ,只要双方相互重视 ,诚意合作 ,共同努力 ,相信中越经贸合作的前景是良好的。     

Hard thresholding regression

In this paper, we propose the hard thresholding regression (HTR) for estimating high‐dimensional sparse linear regression models. HTR uses a two‐stage convex algorithm to approximate the ?₀‐penalized regression: The first stage calculates a coarse initial estimator, and the second stage identifies the oracle estimator by borrowing information from the first one. Theoretically, the HTR estimator achieves the strong oracle property over a wide range of regularization parameters. Numerical examples and a real data example lend further support to our proposed methodology.     

Closure property of consistently varying random variables based on precise large deviation principles

Let X = {X₁, X₂, …} be a sequence of independent but not necessarily identically distributed random variables, and let η be a counting random variable independent of X. Consider randomly stopped sum S_η = ∑^η_{k = 1}X_k and random maximum S_(η) ? max?{S₀, …, S_η}. Assuming that each X_k belongs to the class of consistently varying distributions, on the basis of the well-known precise large deviation principles, we prove that the distributions of S_η and S_(η) belong to the same class under some mild conditions. Our approach is new and the obtained results are further studies of Kizinevi?, Sprindys, and ?iaulys (2016) and Andrulyt?, Manstavi?ius, and ?iaulys (2017).     

Bayesian density regression for discrete outcomes

We develop Bayesian models for density regression with emphasis on discrete outcomes. The problem of density regression is approached by considering methods for multivariate density estimation of mixed scale variables, and obtaining conditional densities from the multivariate ones. The approach to multivariate mixed scale outcome density estimation that we describe represents discrete variables, either responses or covariates, as discretised versions of continuous latent variables. We present and compare several models for obtaining these thresholds in the challenging context of count data analysis where the response may be over‐ and/or under‐dispersed in some of the regions of the covariate space. We utilise a nonparametric mixture of multivariate Gaussians to model the directly observed and the latent continuous variables. The paper presents a Markov chain Monte Carlo algorithm for posterior sampling, sufficient conditions for weak consistency, and illustrations on density, mean and quantile regression utilising simulated and real datasets.     

Documentarians,fair use,and free expression: changes in copyright attitudes and actions with access to best practices

This study, based on a survey of 489 documentary filmmakers, is a case study in copyright policy in and through practice. It assesses the changes in documentary production practice around clearance of copyrighted material since the creation of the Documentary Filmmakers' Statement of Best Practices in fair use in 2005. Fair use, an exotic and occasional feature of documentary film in 2004, has become well known and commonly employed. Creative options for filmmakers concerning the use of third-party material have dramatically improved with changes in norms after the issuing of the Statement. Attitudes about fair use are strongly associated with free expression and creative opportunity, and vary with experience. Where filmmakers have changed work because of copyright concerns, they themselves rather than any gatekeeper have made the decision to do so. Where change is associated with fair use, risk is a common concern. Newer filmmakers are more likely to support the use of copyrighted material to make new work, but less likely to know about fair use, and also more likely to have experienced takedowns online. Both education about and experience with fair use appear to have an effect on practice. Filmmakers continue to lack reliable information on the actual risk landscape, and about fair use on digital platforms.

时代新发展需要新的哲学认识路线

当今时代出现的迅速而剧烈的新发展状况,需要我们进一步深化认识世界的方式,探索如何实现对事物的预见性认识。 从系统论的角度来看,除了外部联系和内部联系,事物自身还存在一种重要的联系：间部联系。间部联系的提出,能够让我们 从可持续角度更深刻地认识事物,洞察事物的导源与归宿,用“认识链”应对“问题串”和“矛盾群”。
