This assignment is my original work and no part has been copied/ reproduced from any other person’s work or from any other source, except where acknowledgement has been made (see Learning, Teaching and Assessment Policy 5.1). This work has not been submitted for any other course/subject (see Learning, Teaching and Assessment Policy 5.9). This assignment has not been written for me. I hold a copy of this assignment and can produce a copy if requested. This work may be used for the purposes of moderation and identifying plagiarism.. Note definition of plagiarism and self plagiarism in Learning, Teaching and Assessment Policy: Plagiarism: reproduction without acknowledgement of another person’s words, work or expressed thoughts from any source. The definition of words, works and thoughts includes such representations as diagrams, drawings, sketches, pictures, objects, text, lecture hand-outs, artistic works and other such expressions of ideas, but hereafter the term ‘work’ is used to embrace all of these. Plagiarism comprises not only direct copying of aspects of another person’s work but also the reproduction, even if slightly rewritten or adapted, of someone else’s ideas. In both cases, someone else’s work is presented as the student’s own. Self Plagiarism: the use of one’s own previously assessed material being resubmitted without acknowledgement or citing of the original.
