Civic Hackathons: Innovation,Procurement, or Civic Engagement?

At all levels, governments around the world are moving toward the provision of open data, that is, the direct provision to citizens, the private sector, and other third parties, of raw government datasets, controlled by a relatively permissible license. In tandem with this distribution of open data is the promotion of civic hackathons, or “app contests” by government. The civic hackathon is designed to offer prize money to developers as a way to spur innovative use of open data, more specifically the creation of commercial software applications that deliver services to citizens. Within this context, we propose that the civic hackathon has the potential to act in multiple ways, possibly as a backdoor to the traditional government procurement process, and as a form of civic engagement. We move beyond much of the hype of civic hackathons, critically framing an approach to understanding civic hackathons through these two lenses. Key questions for future research emphasize the emerging, and important, nature of this research path.     

也谈图书馆的网站建设

图书馆是公益性单位,图书馆不仅需要管理好图书,管理好内部事务,更需要与读者沟通,为读者服务。图书馆网站是图书馆服务广大读者的窗口和平台,网站建设的好坏是当今评价一个图书馆服务好坏的标准之一。但是目前的图书馆网站存在很多令人不满的问题,通过对这些问题的描述,进而提出解决这些问题的方法,并提出网站的建设不仅需要完美的设计,更重要的要舍得花人力和精力去维护。     

Hyperlinks citations, reproducing original works

A hyperlink (or simply a link) is a citation of an electronic address where further information can be found but, additionally, navigates the surfer almost instantaneously to material hosted anywhere on the Internet at a mere click of a mouse. Controversy arises because either the composition or functionality of the hyperlink can potentially infringe property rights of the claimant. Many have written about the hyperlink as a navigation tool authorising or contributing to infringement of copyright by a third party.¹This article concentrates on the composition of an external hyperlink, as a citation. Part 2 outlines the nature of Internet communication and explains why hyperlinks are often controversial. Part 3 asserts when copyright subsists in original literary works, but because a hyperlink may incorporate diverse formats, this part also addresses the protection of other works including the issue of composite works covered under section 1(1) of Copyright, Design and Patents Act, 1988. Applying copyright principles, it suggests that a hyperlink reproducing an identifiable part of a web page capable of standing apart from its context can infringe copyright in the web page containing the part. That said the claimant might face difficulty in demonstrating that the work is substantive or, where the hyperlink consists of diverse inputs, in categorising the subject matter. Part 4 acknowledges the significance (electronic) collections and therefore defines a database falling within the Databases Directive.² It then highlights challenges presented by copyright and sui generis right relating to databases concluding that reproducing an identifiable part of author compiled work can infringe copyright and/or sui generis right therein but the same is not true of search engine generated returns. Part 5 concedes that, in practice, subsistence of copyright and/or sui generis right is open to challenge because the part reproduced in a hyperlink may not be substantive, may not easily fit into the category of protected subject matter or lacks ‘substantial investment.’ Nevertheless, it argues that proving infringement in an identifiable part of a web page reproduced in a hyperlink remains the most viable option for indirectly controlling access to the target page, which may itself be unprotected by copyright.     

UK government's Open Standards Consultation – A step in the wrong direction?

This paper comments on UK government's Open Standards Consultation which opened on 7 February 2012. It questions the UK government's mandating of open standards defined as standards which include patents licensed on a royalty free basis. The paper suggests that instead of promoting a level playing field, the government's policy will actually restrict competition and hinder interoperability. This policy is contrary to EU policy in a number of different fields which have all accepted, despite significant in-depth debate on this issue, that the best way to ensure the most effective competition, innovation and interoperability is to allow both royalty free patents and royalty bearing patents to compete provided the latter are licensed on FRAND terms. Lastly the paper suggests that the public procurement rules are not the place to apply industrial policy, instead a full market analysis should be conducted involving other government departments such as BIS and the IPO.

NFIQ 2.0用于指纹质量控制的可行性及方法

目的测试NFIQ 2.0标准计算指纹质量评分模块在活体采集和油墨捺印指纹质量控制上的可靠性,研究利用NFIQ 2.0指纹分值综合判断指纹质量的可行性和在实际工作中的使用方法。方法一是利用NFIQ 2.0模块接口程序结合VS2015 C#编程语言制作指纹质量评分软件。二是记录20张指纹图片放置在采集框上、下、左、右、中五个位置时NFIQ 2.0的分值,计算平均偏差、最大偏差和相对偏差。三是对在指纹数据库中随机选出的1334枚活体采集和油墨捺印指纹(8位灰度、500 dpi BMP格式指纹图片)进行评分,将得出的分值与通过人工检查该1334枚指纹在指纹系统中自动提取的特征所计算的特征准确率,形成线条图并制作拟合线,通过线条图和拟合线研究NFIQ 2.0分值与特征准确率之间存在的关系。结果从平均偏差、最大偏差和相对偏差分析,指纹图片放置位置对NFIQ 2.0分值的影响很小。利用线条图和拟合线进行统计时,NFIQ 2.0分值与特征准确率之间呈现出一定的对应关系,NFIQ 2.0分值高的指纹,系统自动提取的特征准确性相对较高,反之相对较低。并且,分值在41~100之间时,特征准确率稳定在80%以上。结论NFIQ 2.0标准计算指纹质量评分模块可以用于大批量活体采集和油墨捺印指纹的辅助质量检测,在实际工作中可将NFIQ 2.0模块嵌入活体采集软件和指纹系统档卡扫描中,设定合理的阈值,对提高指纹采集的质量检测效率和提升指纹采集质量将有较大帮助。
