Amazon Probed by British Competition Watchdog_我的网站

A | 2100多年前,古希腊天文学家喜帕恰斯(Hipparchus)绘制了恒星图--在很长一段时间里,这被认为是人类最早的为恒星体指定数字坐标的尝试。 E-commerce giant Amazon is under investigation by the UK's competition watchdog over claims it favors its own warehouses over third-party sellers.,The Competition and Markets Authority (CMA) will look into whether customers are getting a "worse deal" due to the online retailer giving an unfair advantage to its retail arm or sellers who use its services in the Amazon UK Marketplace.,In particular, the probe will examine how Amazon uses third-party retailers' data and its criteria for access to the "Amazon Prime" service, which includes free deliveries. It will also look at how Amazon decides which company's product has the privilege of featuring in the instant "Buy Box" on the website's home page.,"Millions of people across the UK rely on Amazon's services for fast delivery of all types of products at the click of a button," said CMA general counsel Sarah Cardell. "This is an important area so it's right that we carefully investigate whether Amazon is using third-party data to give an unfair boost to its own retail business and whether it favours sellers who use its logistics and delivery services - both of which could weaken competition.",Bezos’ $500M Megayacht Stranded After Dutch Firm Abandons Bid to Dismantle Rotterdam Bridge3 July, 04:03 GMT,"Thousands of UK businesses use Amazon to sell their products and it is important they are able to operate in a competitive market," Cardell added. "Any loss of competition is a loss to consumers and could lead to them paying more for products, being offered lower quality items or having less choice.",Billionaire Amazon founder Jeff Bezos also owns the liberal US Washington Post newspaper. The company has been criticized for its treatment of warehouse staff and its resistance to recognizing trade unions.。但是,尽管它名声在外,这篇论文却只能通过另一位古代天文学家Claudius Ptolemy的著作来了解,他在大约400年后编制了自己的天体清单。而现在,研究人员认为他们已经发现了隐藏在一本中世纪希腊手稿中的喜帕恰斯的失落的历史文件的碎片。本周发表在《天文学史》杂志上的一份关于这一发现的研究报告指出:“这一新证据是迄今为止最权威的证据,使重建喜帕恰斯的星图取得了重大进展。这一发现可以为天文学的历史带来新的启示。”被称为“三角学之父”的喜帕恰斯,通常被认为是古希腊最伟大的天文学家。他的部分星图似乎出现在“Codex CliMaci Rescriptus”中,这是一本叙利亚语文本的书,其中的羊皮纸页被擦掉,可以重新书写,但仍有其早期形式的可见痕迹。这本特殊的重写本存放在埃及西奈半岛的希腊东正教圣凯瑟琳修道院里。来自早期手稿电子图书馆和位于罗切斯特理工学院的拉撒路项目的团队利用不同波长的光揭示了被删除的文字和数字,这种技术被称为多光谱成像。索邦大学和剑桥大学的研究人员随后能够破译四个星座的描述。这似乎不仅揭开了喜帕恰斯制图的面纱,而且研究小组还说新发现的数字证据与真实的恒星坐标高度一致。这将使喜帕恰斯的目录比Ptolemy更晚的版本更加准确,尽管研究人员承认他们使用的是一个小样本,而且在喜帕恰斯的星图中没有保存下来的部分可能存在重大错误。

B | 随着先进的数字技术不断恢复因文件损坏和变质或故意删除而丢失的重要文化遗产,科学家们说Codex Climaci Rescriptus可能会揭示出更多喜帕恰斯的恒星观测。
