云计算与知识产权

在中国以及世界各地,一场重大的计算技术变革将要展开:计算技术将开始向“云端”过渡. 简单地说,有了云计算,远程服务器可以通过网络提供软件功能服务.这些服务器可能位于街边的某个位置,可能分散于全国各地,也可能在世界的另一头.云端不仅可降低计算的成本和增强功能,而且还可使人们在网上协作和沟通更加便利,并且允许用户通过任何一台联网的计算机得到需要的数据或使用需要的应用软件.许多人认为云计算将引发一场在规模上可以和个人计算机及互联网变革相当的重大转变.     

How Weakly Institutionalized Parties Monitor Brokers in Developing Democracies: Evidence from Postconflict Liberia

Political parties in sub-Saharan Africa's developing democracies are often considered to lack sufficiently sophisticated machines to monitor and incentivize their political brokers. We challenge this view by arguing that the decentralized pyramidal structure of their machines allows them to engage in broker monitoring and incentivizing to mobilize voters, which ultimately improves their electoral performance. This capacity is concentrated (a) among incumbent parties with greater access to resources and (b) where the scope for turnout buying is higher due to the higher costs of voting. Using postwar Liberia to test our argument, we combine rich administrative data with exogenous variation in parties' ability to monitor their brokers. We show that brokers mobilize voters en masse to signal effort, that increased monitoring ability improves the incumbent party's electoral performance, and that this is particularly so in precincts in which voters must travel farther to vote and thus turnout buying opportunities are greater.     

Political Brokers: Partisans or Agents? Evidence from the Mexican Teachers' Union

Political brokers mobilize voters all over the world, yet little is known about what motivates them to do so. This article theorizes about two drivers of brokers' efforts: (1) incentives—monetary rewards or sanctions—and monitoring and (2) partisan attachment. We examine our theory using data on the Mexican National Educational Workers Union (SNTE), Latin America's largest union and a well‐known political machine. Consistent with the role of teachers as brokers, we find that the vote share of parties supported by the SNTE machine is higher in polling stations located in schools. This effect is absent when teachers are asked to mobilize voters in support of a party for which they have no partisan attachment, and it is uncorrelated with the union's monitoring capacity. This suggests that partisan attachment, rather than incentives and monitoring, explains the SNTE's effectiveness as a political machine.

Does Observance of Religious Holidays Affect Agricultural Productivity and Household Welfare? Evidence from Rural Ethiopia

This study examines whether traditional customs affect household's welfare by taking the case of the work prohibition related with religion in rural Ethiopia. Although the anecdotal evidence suggests that work prohibition by the Ethiopian Orthodox Church, to observe the religious holidays, is one of the reasons for the high poverty incidence in Ethiopia, the estimation results do not show that there is a significant effect of the number of religious holidays observed on agricultural productivity and household welfare. Observance of religious holidays affects crop choice and income source.     

Victim of a dictatorial regime: identification of Mr. Roberto Gomensoro Josman

Forensic cases are ideal to test osteological techniques developed by physical anthropologists. Forensic anthropology is a scientific discipline that applies population-based standards to individual skeletal remains. Many complex techniques are used in an attempt to make a positive identification. Several of these techniques, specifically digital video superimposition and DNA, were used to identify the victim in this case. The purpose of this paper is to describe anthropological techniques used to identify the remains of an unknown person who was later identified as Mr. Roberto Gomensoro Josman, the victim of a Uruguayan dictatorial regime. Mr. Gomensoro Josman disappeared after authorities of the Uruguayan dictatorial government (1973-1984) arrested him. Six days later an unknown body was found floating in Lake Rincon del Bonete. The corpse was found tied with wire and weighted with three large stones used to keep the body submerged. An autopsy was performed and the body was buried as an unknown person in the grave identified as number 10936 of Tacuarembo Cemetery. On December 2002 the Peace and Justice Service asked the local judge to authorize the exhumation of the remains. The exhumed body was headless. An investigation revealed that the local medical examiner who had autopsied the remains on March 1973 had retained the victim's skull in his office. Osteological analysis indicated the victim was a white male in his 20s. Four good quality photographs of Mr. Gomensoro who was known to be missing were compared with the skull. To confirm the identification from the video a DNA analysis was carried out comparing the victim with relatives. DNA typing confirmed the results of the earlier identification.
