We should read the question carefully: "

Can we present a published paper in a conference? I have published a paper, now I want to present it at a conference. "

Yes, Yes, Yes, you can present a published work at a conference if it is just presenting and not submitting a paper for the conference proceeding, and the conference requirement did not say otherwise. A lot of conference (e.g. Institute of Food technology, IFT) these days only have special sessions where experts on a topic are invited to speak on a subject. Most speakers collate past - published and current data to buttress their points. I have had to present such papers in the past. However, if the conference requirement is that you only present unpublished works, stick to that.

At first, I would suggest careful reading of the announcement of the conference, with a focus on guidlines and themes.

Overall, it may not sound ethical enough to me. But that's as far as I can know and say.

I am pretty sure though that you can present another part of the same research and work that led you to the published paper. Same research with another focus. A part that you have not analyzed or published yet.

But I insist that reading carefully the connference announcement should b ethe first step.

Scientific conferences will not accept an "old" paper, that is, one which has already been published. This is for copyright reasons and pragmatic reasons, because any interested parties do not have to come to the conference to access the paper.

What I suggest is that you present your paper at a symposium that you organise.

I agree with Prof. Ian Kennedy.

Actually I did not want to publish it again, but want to only present it as means of promotion.

It can be presented in a symposium for such purpose

I think you can present a paper in a conference and then work on it further for publication

Yes, you can present a reduced form of its content with focus on the research approach, and results such that the original paper is cited. It is also preferable to mention at the abstract or introduction that you are presenting a previously published work. Usually, a conference paper may be subsequently extended to a journal article. Your case is an opposite situation, but it is OK.

Can we present a published paper in a conference?

Not advisable & shouldn't be the same as your published paper. Also please check with the conference organizing committee on their guidelines. Because my understanding is all the research conferences require author to submit their paper & received clearance before they can present in the conference. Moreover, after the presentation, the paper will / can be part of the published conference proceeding which might similar to your earlier published paper.

No. findings published in any publication channel earlier cannot acceptable in the conferences and seminars afresh. Best way you to modify findings again in a new scenario then published as conference / seminar proceedings.

On the published paper, find some findings and improvements and work on that. Then, you will write a paper and submit to the conference chair. After that, move to conference and get the feedback from the experts and audience by open discussion

I feel you have received the answer. It is unethical to repeat same thing twice. Many people especially third world countries do. However, at the same time, if it is submitted paper and you are awaiting for the outcome, that case it is okay for partial presentation. This is my philosophy.

This unethical!

Yes @Akinbode A. Adedeji this is what I want to do. I only want to present my published work, not to publish it again.

I believe you can present your published work at a conference, provided the conference did not say you couldn't. Conferences are meant to share outcome of research - published or unpublished. However, if the conference requires that you submit a paper on your presentation, it is generally assumed that the work is not published. You can always check with the conference organizer to be sure you are not violating anything.

I think, to present the ideas (own results) in any conference is allowed because the conferences are the platform for sharing ideas and further discussion. To publish the contents (from published paper), you have to careful about the copyright issues. This my view.

You can present your paper orally in conferences or whatever but it is unacceptable to publish a journal paper twice. The opposite way is somehow possible. Top conference papers may be invited for publication in related journals. However, the second paper must be and extended and clearly different version of the original conference paper.

This is a debatable question. Mostly, you publish your preliminary results in a conference, then you publish the final results in a journal. On the other hand, some researchers reuse the published journal paper in a conference by representing the text/results. However, if doing so, the author should consider two things: 1) journal copyrights, (2) Conference consent for presenting published work.

A conference is a meeting of academics of a particular range of disciplines to discuss the progress in these disciplines. Here I often encounter that findings are presented that have been published already. I would be unhappy to just hear a presentation of a paper I already did read, but some findings embedded in new aspects is certainly not only possible but even an advancement of the discipline.

Yes, we can but it is unethical to repeat same researcwork twice.
