Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

纵向一体化网络的接入定价研究

中国铁路、煤气、自来水、邮政等绝大多数网络型产业的结构改革将选择纵向一体化与自由接入作为突破口，研究纵向一体化网络的接入定价理论和政策已成为中国网络型产业规制政策研究的一个重要问题。本文首先依据资源最优配置、次优配置、生产效率等原则，研究了不同的接入定价理论，详细探讨了不同的接入定价方法，最后进一步分析了纵向一体化网络在不同政策目标下的接入定价政策选择。     

The social process of internet appropriation: Living in a digitally advanced country benefits less well-educated Europeans

We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries.     

On the Legislative Investigation and Analysis of Criminal defendant’s Access to the Right to counsel

我国法律规定了被告人享有辩护权,并且这种权利的行使可以得到律师的帮助,律师在刑事诉讼中的职责就是依据事实和法律为委托人进行辩护,维护其合法权益。但是从现行制度下被告人和辩护律师所享有的权利来考察,很难说被告人真正地、充分地享有辩护权,因为在刑事诉讼中被告人和辩护律师所享有的权利十分有限,辩护律师在刑事诉讼中也不享有完整的辩护权,同时司法现况与被告人获得律师帮助权的基本要求差距甚大。本文对我国被告人获得律师帮助权制度及其运行进行了考察,并对相关问题进行了分析。

Can Mobile Money Help Firms Mitigate the Problem of Access to Finance in Eastern sub-Saharan Africa?

ABSTRACT

Mobile money is a mobile-phone-based financial tool that can transfer money safely and quickly across a wide geographical area. Mobile money has transformed the way businesses in Eastern sub-Saharan Africa operate. Nowadays, banks team up with mobile-money-service providers and pay interest on deposits and grant loans based on financial transactions in mobile-money accounts. In this paper, these recent developments are investigated in order to determine whether the adoption of mobile money by firms can actually help them mitigate the vexing problem of access to finance. To answer this question, the World Bank’s Enterprise Surveys Program data set for the year 2013 is used, thus making the study applicable to the present time. The results obtained, after controlling for a large number of firm-level characteristics and using a newly introduced measure to identify access-to-finance status of the firms, indicate that firms which use mobile money are more likely to obtain loans or lines of credit. Further analysis shows that the firms that use mobile money are more productive than other firms in the region.     

一种利用优先经验回放深度Q-Learning的频谱接入算法

针对认知无线传感器网络中频谱接入算法的频谱利用率不高、重要经验利用率不足、收敛速度慢等问题,提出了一种采用优先经验回放双深度Q-Learning的动态频谱接入算法。该算法的次用户对经验库进行抽样时,采用基于优先级抽样的方式,以打破样本相关性并充分利用重要的经验样本,并采用一种非排序批量删除方式删除经验库的无用经验样本,以降低能量开销。仿真结果表明,该算法与采用双深度Q-Learning的频谱接入算法相比提高了收敛速度;与传统随机频谱接入算法相比,其阻塞概率降低了6%~10%,吞吐量提高了18%~20%,提高了系统的性能。
