The obvious answer would be "Yes, of course." This even accounts for any type of grey literature, bachelor thesis, etc.

Then, why do we even have this question or discussion?

Supervisors do not always have the time to develop a paper based on good ideas provided by students and students might fail due to their inexperienced way of presentation.

Let me make a big jump and criticize many of the recent ("so-called" structured) literature reviews that focus on common data bases, works with Impact factors and alike. But they neglect grey literature or sources. If there is an interest on the topic and knowledge about ideas in grey literature, this must be inlcuded. So, if a good idea in a thesis, let it be a starting idea from a supervisor or a student or an extension or modification from the same persons, then get it in.

Food for thought, indeed. We should not primarily be interested in getting papers into the CV, we should strive to advance science.

It is perfectly acceptable to cite an idea or finding from your own previous work, if this is what you have in mind

I cannot see any problem. Why not??

i can't see any problem if all quotations are correctly cited... but I prefer to ask my students to rewrite the quoted paragraph in addition to citation, in such cases.

Well we cite sources, mainly, for two reasons. One we cite the data sources in case some data has been taken from them for analysis purposes, second, we cite documents to refer to research findings/inferences reported in them. Now if it is the former case I don't find any harm in citing a scholar's own previous work. However, in the later case I would recommend caution because one should always build his/her research on, as much as possibly, sound foundations that may not be possible unless a research finding is peer reviewed, published and/or widely available to the research community for critique. MS work is usually unpublished and not widely reviewed so it may not be able to provide that sound foundation.

Having considered this precaution I don't find any harm quoting someone's own previous work.

Thank you Dr Stefan Voss. Your explanation has been very helpful.

Yes, of course, researchers build and develop on their previous work. If a current study is related to a previous study, why not? Cited our previous work gives validity and currency to our previous and current study.

I am also in the affirmative!!!

If Master's thesis material is unpublished, one can upload the thesis on Research Gate itself and request for open review. This way, your work gets read by peers and you may also get meaningful feedback and suggestions for improvements and future work. In time, if relevant, you may also quote from that, since now it is in public domain and has also been made available for public scrutiny.

One is allowed to quote both his/her published and unpublished academic works in his/her PhD study. That is one way of publicising ones previous academic work and record, particularly if the work relates to the current study.

I fully agree. If it is relevant, we must quote. If we don't quote our own relevant work, then how do you expect others to quote your work?

Anything relevant should be quoted as long as publicly available. And as A.G. Ramakrishnan mentioned, RG enables people to make these documents - unpublished in peer review journals or even conferences - available to everybody !

Yes off course..

I DO THINK the same that there is no harm to cite own work if relevant. Master's thesis is itself a scholarly work and no wrong if properly cited.

Thanks

Yes, in research you divorce the author and previous works. In my opinion, as long as your work was published in peer reviewed journals, you can quote in in any article or academic thesis

Of course, you can cite yourself if your citation from your Masters thesis is relevant to your PhD thesis. Although, one should not abuse it.

The time line is important! The Masters's theses usually belongs to earlier stage of develmoment of scientific research. Therefore citation of your own work is OK but always with clear information when the paper is presented to the academic authorities even it is better if the departmental policy is to keep an own internal library with student's masters theses. RG obviously is the best solution to put your earlier work in public with "time line" notificatition!

If your PhD thesis applies to your master thesis, and if you revealed unique empirical findings or discussions in it, why not?
