网络文学版权保护探析

侵犯网络文学著作权尤其是信息网络传播权的现象在当下十分严重。侵权的模式包括"云霄阁模式"和"百度模式"。它的背后既体现了社会公众、网络服务提供者和版权人之间的利益平衡,也是互联网精神、权利意识和商业模式三者博弈的结果。解决侵犯网络文学版权的问题需要注重培育公众正确的互联网意识、完善法律制度建设、创新文学网站的盈利模式及大力发挥社会组织的作用。保护网络文学著作权对创新虚拟社会管理有重要意义。     

意识形态之争探赜

伴随着阶级和国家的产生,关于意识形态的争论从来没有停止过。意识形态之争的表象是话语权、信奉者和影响力、感召力的争夺;意识形态之争的根基源于意识形态的科学性、传播方式和经济基础;意识形态之争的实质归于阶级和国家利益的维护。当前,认清意识形态争论的表象、阐明意识形态争论的根基、揭示意识形态争论的本质对于我国主流意识形态的建设具有重要意义。     

On additive-multiplicative hazards model

In survival analysis and reliability theory, a fundamental problem is the study of lifetime properties of a live organism or system. In this regard, there have been considered and studied several models based on different concepts of ageing such as hazard rate and mean residual life. In this paper, we consider an additive-multiplicative hazard model (AMHM) and study some reliability and ageing properties of the proposed model. We then specify the bivariate models whose conditionals satisfy AMHM. Several properties of the proposed bivariate model are investigated and adequacy of the model is evaluated based on a real data set.     

A Semiparametric Regression Model for Longitudinal Data with Non‐stationary Errors

Motivated by the need to analyze the National Longitudinal Surveys data, we propose a new semiparametric longitudinal mean‐covariance model in which the effects on dependent variable of some explanatory variables are linear and others are non‐linear, while the within‐subject correlations are modelled by a non‐stationary autoregressive error structure. We develop an estimation machinery based on least squares technique by approximating non‐parametric functions via B‐spline expansions and establish the asymptotic normality of parametric estimators as well as the rate of convergence for the non‐parametric estimators. We further advocate a new model selection strategy in the varying‐coefficient model framework, for distinguishing whether a component is significant and subsequently whether it is linear or non‐linear. Besides, the proposed method can also be employed for identifying the true order of lagged terms consistently. Monte Carlo studies are conducted to examine the finite sample performance of our approach, and an application of real data is also illustrated.     

An International Comparative Study on Women's Pension Rights and Their Economic Risks

This article examined the theoretical meanings of pension rights and analyzed their effects on women's economic risks in developed countries. First, based on the status of a citizen, worker, parent, and spouse, this study investigated how pension benefits are guaranteed as a citizen regardless of work history, the degree to which women's disadvantageous situations in the labor market and unpaid work are compensated by public pension as workers and parents, and how marital status is treated in the different pension systems. Second, analysis of the effect of pension rights showed that individual rights is a significant factor to prevent economic risks of elderly women. Derived rights did not seem to secure the economic welfare of elderly women, at least in a comparative context. This finding suggested that developing individual rights, rather than derived rights, is the way to guarantee long‐term elderly women's economic welfare.     

对中国经济运行状况的分析

从经济的投资、消费和出口数据看,中国经济增速确实在下行。为了保持中国经济8%的增速,我们已付出了很高的代价;经过35年的高速增长,在各行各业产能基本过剩的情况下,中国经济增速正在下移。观察1950年代后日本、中国台湾和香港地区经济发展的过程,其经济高速增长后,也是一个台阶又一个台阶地下来。中国不能再靠高投资来推动经济增长。     

在文本与实践之间——法律移植之困境再论

当前我国法制建设在制度移植与重生方面面临着一种困境，即法制建设究竟是应该整理传统以利用本土资源并进而实现传统的创造性转化，还是应该以西方制度演化史所积淀的现代法制模式为榜样进行整体或局部的法律移植，学界对此亦存在相当的论争。然而值得怀疑的是，这些不同角度的理论进路究竟在多大程度上能给当前的困境提供一种出路，甚而有学者以为当前的制度变革本就无解。     

Classical estimation of hazard rate and mean residual life functions of Pareto distribution

Abstract

In this paper we find the maximum likelihood estimates (MLEs) of hazard rate and mean residual life functions (MRLF) of Pareto distribution, their asymptotic non degenerate distribution, exact distribution and moments. We also discuss the uniformly minimum variance unbiased estimate (UMVUE) of hazard rate function and MRLF. Finally, two numerical examples with simulated data and real data set, are presented to illustrate the proposed estimates.     

欧洲债务危机的主要成因分析

肇始于希腊的欧洲债务危机到目前为止都没有停息的迹象,甚至还呈蔓延之势。欧洲债务危机爆发的直接原因是在金融危机的背景下,政府支出规模持续扩大,导致财政赤字居高不下,最终使得国债规模超过政府的偿还能力,出现明显的违约可能性。同时,国际竞争力不足,导致出口受阻,使得资金问题更加严重。从更深层次看,产业结构不合理,经济发展速度缓慢,过低的投资率和储蓄率及过高的储蓄投资转化率,都是导致欧债危机的重要原因。
