I should like to answer the question with "no". Normally, state universities have relatively uniform examination regulations for doctoral studies in the individual degree programmes, which are issued by the ministry. Certain requirements must be fulfilled here. The doctoral thesis with all research materials must be submitted to the Dean of the Faculty, and also the expert opinions - at least 2 professors of the faculty, sometimes additional outward professors - which recommend acceptance or rejection (due to certain deficiencies) in their expert opinion to the Faculty. The Dean notifies all faculty members in writing that a doctoral thesis and the expert opinions are available for possible inspection. Every professor has the right, after examining the dissertation in question, to draw up his or her own expert opinion - e.g. if he or she considers the work to be insufficient. After the deadline for faculty members to inspect the dissertation has expired, the candidate must either take an examination in the main subject and 2 minor subjects, or he must defend his dissertation with the research result in a lecture and subsequent discussion with some faculty members (often with the participation of the university public). This is a normal standard at European or, say, Western universities.

Private universities sometimes have different regulations, but the top universities tend to have higher requirements, not lower ones.

It is completely impossible for an institute - and not a faculty - to issue any PhD -certificate after the candidate has published an abstract somewhere. If something like this actually happens, then one can only regret that the candidate has not set himself higher standards. He harms his career if he intends to start an academic career. In EU countries, ministries would probably not tolerate such a practice.

I think this depends on the university system

obviously, in general, the answer is "No" but in particular he/she has made outstanding contribution to research in particular area that he /she has even single published work (single paper) that are published in very/very/very reputed journal like "NATURE" consider to be research scholar. This flexibility has to be accepted in the university system throughout the World. No problem.

"NO" because in PhD student should add something to the science (novelty) not shows something already exist. In studying Phd the most important is the problem statement and how to fix this problem. If student publish review paper that means he indicate a problem without any real solution!.

PhD students should be allowed if the review paper does not reveal the main results of the research. If this paper says it all, the PhD defense or "grill, as it was described in some British universities" will become of little value or may be meaningless.

The PhD dissertation ought to be kept as a secret until the day of its defense. Even after that, what will be published must be agreed upon between the PhD student & his or her supervisor(s) under a general guidance of the university's administration.

Ph.D. student write a review as a part of his work, i think he could extend the review to publish it to get his Ph.D.

To all and Khaled Muftah Elsherif

Perhaps I did not understand the question correctly in my first answer. One understands the question - this is how I have interpreted it - that in order to obtain the PhD title it is sufficient to publish a summary of the work, and the dissertation itself no longer plays any role, remains uncontrolled and disappears - perhaps - never to be seen again, in the bookshelf of the doctoral supervisor. If this is practice, I do not think it is scientifically appropriate. On this basis, quantitative research cannot be presented and discussed - as has been requested.

I remember that, many decades ago, one or more professors of an institute abroad, perhaps on some island offered interested people unofficially a simple way of obtaining a doctorate. One paid a certain sum ("expense allowance") to travel there, wrote a page about some subject, which was "published" in the institute at the dashboard or in the "house magazine", and the candidate returns home satisfied with the doctorate.

At that time, there were also inquiries as to whether any people from the business world who liked to adorn themselves with a title had come to their PhD in this way. Today there are completely different prerequisites for getting a PhD with an easy way. Recently some politicians, even ministers, stood in the light of the public when it became clear that they had mostly copied something meaningful from Internet texts, submitted it to the faculty, who didn't realized the fake, and had published it as their dissertation. Such practices are forbidden and are strictly controlled today.

In fact, the dissertation is always a challenging path that concerns one's own research and the results of which must be discussed by other researchers. In the past, the doctoral regulations stated that after the acceptance of the dissertation by the faculty, not only the original but also a larger number of complete copies of the dissertation - I remember the number 150 - had to be delivered to the dean's office, so that this dissertation could be accessed both in one's own university library and in all other university libraries. Today, the dissertation can also be published on the Internet or with a CD, which can be downloaded as a pdf file for all those interested in the university library concerned.

Therefore ABSTRACTS cannot be recommended in any way in which journal they are published. The best way for a candidate's academic career is still to publish a book with a reputable publisher, even if this is usually not quite cheap.

Dear Muhammad Aamir Shafique Khan could you please explain your question in more details? Do you mean is it Ok to the student to graduate with only one review paper beside his thesis? Instead of publishing a research paper? Or just by publishing a reviewing paper

The answer, I believe, must be “no”. In Brazil, students only get awarded the Phd title after writing an innovative dissertation; not shorter than 30,000 words, I must add. Publishing a couple of relevant journal articles is usually also required.

Absolutely "NO"

I would say "No" because Ph.D. candidate must make a new scholarly contribution to a particular area of knowledge through his own original research.

The answer is "NO"

no

Its a common practice of evaluating the confidence of the PhD student

If ph. D in metaanalysis then no question for awarding ph. D on review.

In review research also did finding and analyze and summarize it's also research.

if any scholar summarizes research work of any particulat topic or area and publish in form of review paper, then what work he or she has done to get doctorate degree. In my opinion, answer is NO.

In my opinion two things one invention another innovation . invention not always happens and majorly innovations. Majority of Ph.D on innovations .Next in Ph.d scholar work on innovations on labs that majority bof people consider as ph.D simultaneously person work further Innova tions collect and information and implement for eg repurpose drug innovations similar aa review paper. If repurpose drug accept then review accept in Ph d. Further more People did Ph.d in meta-analysis and its accepted then it's sufficient evidence for Ph.d .

If the amount of work behind that paper equals a thourough research effort of 3-4 years, I'd say yes. But that is highly unlikely.

No candidate should be awarded Doctoral degree on the basis of review article.
