Plagiarism is not allowed in the HKU pursuant to the Regulation 5 of the University’s Regulations Governing Conduct at Examination. In its definition, plagiarism is “the unacknowledged use, as one’s own, of work of another person, whether or not such work has been published.” It consists of two parts: copying and the absence of proper acknowledgement.
It means copying from the published works or the essays of other students without any acknowledgement. It may be noticeable that the source talking about here may be published in traditional text or on the Internet. The test of plagiarism by copying is whether the work will give an ordinary reader a reasonable impression that the work is the original work of the author when it is in fact a copy of the work of someone else.
2. absence of proper acknowledgement.
If one takes a passage from others’ work, he must obtain proper acknowledgement, i.e. put the copied passage in quotation or identify it by using proper indentation, to show to the readers that it is the work of another person, and provide the source. The source must be clearly provided immediately after the copied passages.
One must aware that it may not be legal to post photos on a blog that one has downloaded from the Internet, even in a case the source is credited. It is not only regarded with the proper acknowledgement, there is also a problem of copyright. By copyright law, photo is a type of image that it belongs to the artist who created the artwork. Only they can give permission to reprint the work, and by law, it can only be used with permission. The growing trends in content theft
Different image providers may have different rules on using the image by their viewers. For example, Google Images, one of the largest services offering images for viewing, although they provide location and access into the images, they does not grant any rights to use them for any purpose other viewing them on the web. The viewers always need to read the fine print to see whether the copyright is reserved that permission is required before using. http://images.google.com/help/faq_images.html#copyright
With Flickr, which is more like a platform people use to upload and browse images, the attitude is even more oblique. At the bottom of each Flickr.com web-page, there is a “Copyright/IP Policy” link which takes you to a Yahoo page that states: “Yahoo! respects the intellectual property of others, and we ask our users to do the same.” http://info.yahoo.com/copyright/details.html Roughly, his policy is that one can use the image, with credit, as long as the link is to the image on flickr and not copied onto the site.
All in all, the Bloggers before using any photo downloaded from the Internet always need to be sure whether the copyright is reserved that permission is required before using.
