基于EGRL的管理信息标准博弈分析

运用两阶段斯塔克伯格博弈模型研究EGRL在政府部门管理信息相关者之间的扩散问题。分析了EGRL技术标准的采用对主要职能的机构和大众群体相关者信息共享以及享用的影响。结果表明:当部分利益相关者采用EGRL时,主要相关者获得的信息量以及所享用的利益大;对信息获取者来说,获得信息量大得到利益就大,当得到者信息量较少时享用减少,而采用足够多时享用增加;对未得到者来说,享用变低,信息量变小,总体享用降低。对主要管理者、相关者和大众群体来说,部分采用而不是所有相关者都采用EGRL技术标准才是最佳结果,也就是存在最优的采用数量使得主要人员在EGRL技术扩散中获得最大量信息。     

NEW MEDIA

In 1845 John Lewis Ricardo was among a group who bought the Cooke and Wheatstone British patents for the electric telegraph at a current cost of £10 million. Although many people have examined the history of the telegraph no one seems to have asked the question ‘Why?’ Ricardo was a Member of the Stock Exchange, financier and a leading politician campaigning against monopolies. This paper postulates that his prime objective, while the largest shareholder for the first three and executive Chairman of the Electric Telegraph Company for its first 12 years, was to build a network, obtain and then distribute financial intelligence to its own newsrooms, adjacent to all the Stock Exchanges in Britain. It was not an afterthought as has been widely assumed. Newspapers in the regions took advantage of this new media. When the telegraph companies later formed their own cartel/monopoly, and substantially boosted prices charged to newspapers, Ricardo changed sides and secretly campaigned for their nationalization.     

THE PROMISE OF COMPUTATIONAL JOURNALISM

Computational journalism involves the application of software and technologies to the activities of journalism, and it draws from the fields of computer science, the social sciences, and media and communications. New technologies may enhance the traditional aims of journalism, or may initiate greater interaction between journalists and information and communication technology (ICT) specialists. The enhanced use of computing in news production is related in particular to three factors: larger government datasets becoming more widely available; the increasingly sophisticated and ubiquitous nature of software; and the developing digital economy. Drawing upon international examples, this paper argues that computational journalism techniques may provide new foundations for original investigative journalism and increase the scope for new forms of interaction with readers. Computational journalism provides a major opportunity to enhance the production of original investigative journalism, and to attract and retain readers online.     

When Everything Else Fails: Radio Journalism During Hurricane Maria in Puerto Rico

ABSTRACT

In an era of over-reliance on online media technologies in disasters, this research examines the journalistic functions played by Puerto Rican AM radio workers during Hurricane Maria. Throughout the emergency there was total loss of electricity and communications, nonetheless local radio continued operations. This study is one of a few that explore journalistic practices during a disaster in the context of a Spanish-language media system. Through a qualitative analysis of in-depth interviews with radio workers, we found that in spite of having preparedness plans, the magnitude of the disaster led to improvization and the embracing of alternative journalistic roles. One of the main barriers was the inadequate technology for this particular context. Radio workers were also victims of the disaster and faced challenges in both their journalistic and first responder roles.     

Partners in Power

This historical analysis examines the relationship between investigative journalists and official sources through the prism of Pulitzer Prize archive materials from 1917 through 1960. Most prize research has focused on the content of winning stories, but this study provides a fuller picture of the process of newsmaking—and policymaking—through an exploration of deliberative material created by prize juries. While the role of the press in these decades and beyond has been conceptualized alternately as a passive lapdog or an aggressive watchdog, this essay offers a more nuanced view of newspapers that are fully entangled with power in society—sometimes collaborating with a faction of power, sometimes confronting a faction, and, often, both at once. Detailed jury notes on the nominations tell the stories behind the investigations, revealing a press that sometimes leads and other times takes the lead from those in positions of official power. The paper adds to the literature on policy and media agenda building, arguing that through investigative reporting, journalists have often been active rather than passive partners in systems of community standard maintenance.     

灾难性事件报道中的评价研究

灾难性事件报道是新闻工作者对灾难性事件的客观描述。我们不仅要关心该类报道所呈现的社会现实,而且更要探究构成它的内在机制。通过运用系统功能语法中的物质过程以及马丁的评价理论对《纽约时报》2005年10月9日关于巴基斯坦地震的报道进行分析,揭示了该报道的态度、立场和观点,彰显了客观性报道背后的意识形态。     

实质损害原则——美国信息隐私保护利益平衡原则

欧盟平衡个人信息隐私权和公共利益的原则是充分利益原则,只有在证明公共利益是充分必要时,才能适当减损个人信息隐私权;美国则更为重视信息自由流动的价值意义,在平衡个人信息隐私权与公共利益的冲突时,采取实质损害原则,保护个人信息隐私免于披露必须证明披露信息对个人造成实质损害或实质损害的威胁。本文在分析我国建设征信体系时所处的背景及所面临的主要矛盾后,建议借鉴美国信息隐私保护的利益平衡观,在个人信用信息的采集和利用方面,采取“宽进严出”的方式。
