Plagiarism

Plagiarism involves the unacknowledged use of someone else’s work, usually in coursework, and passing it off as if it were one’s own. Many students who submit apparently plagiarised work probably do so inadvertently without realising it because of poorly developed study skills, including note taking, referencing and citations; this is poor academic practice rather than malpractice. Some students, particularly those from different cultures and educational systems, find UK academic referencing/acknowledgement systems and conventions awkward, and proof-reading is not always easy for dyslexic students and some visually-impaired students. Study skills education within programmes of study should minimise the number of students submitting poorly referenced work. However, some students plagiarise deliberately, with the intent to deceive. This intentional malpractice is a conscious, pre-mediated form of cheating and is regarded as a particularly serious breach of the core values of academic integrity. The Dual Degree Prorgamme has zero tolerance for intentional plagiarism.

Plagiarism can include the following:

1. collusion, where a piece of work prepared by a group is represented as if it were the student’s own;
2. commission or use of work by the student which is not his/her own and representing it as if it were, e.g.:
3. purchase of a paper from a commercial service, including internet sites, whether pre-written or specially prepared for the student concerned
4. submission of a paper written by another person, either by a fellow student or a person who is not a member of the university;
   1. duplication (of one’s own work) of the same or almost identical work for more than one module;
   2. the act of copying or paraphrasing a paper from a source text, whether in manuscript, printed or electronic form, without appropriate acknowledgement (this includes quoting directly from another source with a reference but without quotation marks);
   3. submission of another student’s work, whether with or without that student’s knowledge or consent;
   4. Directly quoting from model solutions/answers made available in previous years;
   5. cheating in class tests, e.g.
      1. when a candidate communicates, or attempts to communicate, with a fellow candidate or individual who is neither an invigilator or member of staff
      2. copies, or attempts to copy from a fellow candidate
      3. attempts to introduce or consult during the examination any unauthorised printed or written material, or electronic calculating,  information storage device, mobile phones or other communication device
      4. Personates or allows him or her to be impersonated.
      5. Fabrication of results occurs when a student claims to have carried out tests, experiments or observations that have not taken place or presents results not supported by the evidence with the object of obtaining an unfair advantage.

These definitions apply to work in whatever format it is presented, including written work, online submissions, group work and oral presentations.

20.

Attendance Policy

Every student must attend 90% of the lectures delivered in this course and 90% of the practical/laboratory work prescribed for this course. The students falling short of required percentage of attendance of lectures/practical/laboratory work, etc., shall not be allowed to appear in the terminal examination of this course and shall be treated as having failed this course.

In case of illness or other unavoidable cause of absence, the student must communicate as soon as possible with the instructor, indicating the reason for the absence. Prolonged illness of three or more consecutive days must have a medical certificate sent to the department. Excessive absence may result in failure or immediate withdrawal from the course or programme.

20b

Makeup Test, Exams or Quizzes

There will be no makeup tests, exams or quizzes. If you miss a test, exam or quiz, you will receive zero marks. Exceptions may be made for extenuating circumstances or for medical reasons documented by “Student Medical Certificate”. In such a case, it is the responsibility of the student to inform the course instructor immediately.
