中国城市化进程中土地征用补偿边界分析

本文从失地农民的福利入手,分析了征地补偿的现实边界和理论边界。结果表明,政府垄断土地非农化市场严重低估了征地补偿标准,合理的征地补偿应该明晰失地农民的产权和引入市场竞争机制。     

关于岳阳南湖旅游开发主题定位问题的探讨

旅游资源规划的核心问题,乃在把握住资源的基本文化属性,作出科学的主题定位。岳阳南湖本是极富吸引力的优势资源,因为对此认识上的盲目、短视与无知,故其开发利用根本未能达到旅游文化开发的高层面,因而也至今无法进入市场,产生效益。南湖资源人为毁损状况堪忧。要制止目前的盲动作法,要使南湖重焕光彩,形成旅游产品进入市场,必须重新进行主题定位,并采取若干可行措施。     

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.     

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.

论抽象行政不作为侵权及其法律救济

目前,我国行政法学界对行政不作为的研究相当薄弱。中国首例公民状告政府行政“立法”不作为案,使这一理论问题凸显出来。抽象行政不作为是一种违法行为,由于其作用的对象广泛,比具体行政不作为更具有危害性,应将抽象行政不作为纳入行政侵权行为的范畴,对其进行救济。     

特定行业中个人信息保护问题探讨

信息社会里,调和个人信息流动与个人信息保护的问题已引起世界各国的高度关注.通过对大众传播、征信行业和医疗机构三个特定行业中的个人信息保护问题的案例分析,对个人信息保护立法问题作了思考:保护个人信息安全是个人经济生活、社会互动的基础,对个人信息的立法必将推动整个信息化法律体系的建设与完善.国家应在吸收国外个人信息保护经验的基础上,加快中国的个人信息保护立法进程,消除立法藩篱,促进信息流动与信息保护的和谐发展.
