Wikipedia:WikiProject Deletion sorting/Science

This is a collection of discussions on the deletion and merging of articles related to Science. It is one of many deletion lists coordinated by WikiProject Deletion sorting. Anyone can help maintain the list on this page.

Adding a new AfD discussion

Adding an AfD to this page does not add it to the main page at WP:AFD. Similarly, removing an AfD from this page does not remove it from the main page at WP:AFD. If you want to nominate an article for deletion, go through the process on that page before adding it to this page. To add a discussion to this page, follow these steps:

1. Edit this page and add {{Wikipedia:Articles for deletion/PageName}} to the top of the list. Replace "PageName" with the relevant article name, i.e. the one on the existing AFD discussion. Also, indicate the title of the article in the edit summary as it is particularly helpful to add a link to the article in the edit summary. When you save the page, the discussion will automatically appear.
2. You should also tag the AfD by adding {{subst:delsort|Science|~~~~}} to it, which will inform editors that it has been listed here. You may place this tag above or below the nomination statement or at the end of the discussion thread.

There are a few scripts and tools that can make this easier.

Removing a closed AfD discussion

Closed AfD discussions are automatically removed by a bot.

Other types of discussions

You can also add and remove other discussions (prod, CfD, TfD etc.) related to Science. For the other XfD's, the process is the same as AfD (except {{Wikipedia:Miscellany for deletion/PageName}} is used for MFD and {{transclude xfd}} for the rest). For PRODs, adding a link with {{prodded}} will suffice.

Further information

For further information see Wikipedia's deletion policy and WP:AfD for general information about Articles for Deletion, including a list of article deletions sorted by day of nomination.

You are probably referring to me, as I was the one who wrote the first version back in 2021. I had no CoI back then at all, just a wish for her work to be noticed and for her page not to be redirected to her partner's page, as it did back then, which is an insult to a seasoned researcher and writer as she is.

Since then, I have worked with her, and when I wanted to update the page and create a more balanced piece (remove what you may think of as "puffery") I added the CoI and asked for approval of the update. I have now deleted it as I see no point in trying to get that approved, which proved to be right based on your request to even delete the whole page.

I'm not alone in arguing for having this page on Wikipedia and hope some will join the discussion. Since your request for deletion may have been initiated by my Draft:Open systems theory proposal and your opposition to that, I will probably not be able to sway you. In the meantime, I will update the page as planned to make it more representative, as I do agree that it is not there yet. Trond Hjorteland (talk) 08:18, 9 August 2026 (UTC)

The page has been updated with more sources, and promotional language has been removed. This should make the WP:NPROF clearance more obvious. Also, Google Scholar shows sustained citation across the organisational development and action research literature:

• Participative Design for Participative Democracy (1989, ≈274 citations),
• Searching (1999, ≈190),
• "The current version of Emery's open systems theory" in Systemic Practice and Action Research (2000, ≈165),
• A Choice of Futures (with F. Emery, 1976, ≈156),
• Barton, Emery, Flood and Selsky (2004) in Systemic Practice and Action Research (≈115),
• "The search conference: A powerful method for planning organizational change and community action" (with Purser, 1996, =694).

Six works over 100 citations in a small specialist field. Trond Hjorteland (talk) 10:38, 9 August 2026 (UTC)

I did the updates to the page, which probably conflict with the WP:COI process, but I hope that is OK since there is an AfD, you are involved and there is full disclosure about my CoI and the ongoing AfC. More than happy to revert and create a draft page instead. Trond Hjorteland (talk) 11:23, 9 August 2026 (UTC)

• Keep: authors of widely recognized concepts, both by public and by scientific community, are generally considered to be notable. There were concerns about promotional language of the article; the overly promotional language has since been removed. Jean Mélenchon (talk) 14:28, 9 August 2026 (UTC)

  Where is the secondary sourcing to establish this as a widely recognized concept by both the public and scientific community? Where is sourcing establishing the subject's role in this? Were you canvassed to be here? Sulfurboy (talk) 18:47, 9 August 2026 (UTC)

  Sorry for butting in here, but since you asked for secondary sourcing, there are loads of its uses around the world (like Search Conferences and organisational redesigns using the Participative Design Workshops), especially in Australia and the US. A good source is this book: https://www.goodreads.com/book/show/1879091.The_Self_Managing_Organization_ In addition to the citations mentioned above from Google Scholar. Trond Hjorteland (talk) 18:59, 9 August 2026 (UTC)

  This does not demonstrate significant recognition, at all. In fact, an h-index of 7 would demonstrate the exact opposite. Sulfurboy (talk) 19:08, 9 August 2026 (UTC)

  Scopus has a mere 17 of her articles. Not sure which as they are hidden behind a wall. She has authored or coauthored at least ten books, eight edited books, 35 book chapters, 60 journal articles, and contributed 29 institutional research reports, including several national studies. Trond Hjorteland (talk) 19:35, 9 August 2026 (UTC)

• Redirect back to Fred Emery. On Scopus I am not seeing anywhere close to the citations claimed above, with just 196 citations total and an h-index of 7. I'm also not seeing the significant recognition of either "open systems theory" or M. Emery as its co-developer needed for a pass of C1. JoelleJay (talk) 15:27, 9 August 2026 (UTC)

  Why do you use Scopus? It has only 17 of her articles. See the numbers I've given above for her production and the number of citations on Google Scholar. Amazing numbers for a women in science, I should think, Trond Hjorteland (talk) 19:57, 9 August 2026 (UTC)

  @Thjortel @BenAveling, because NPROF advises to use Scopus or WoS and against using Google Scholar for citation counts (bolding mine): The only reasonably accurate way of finding citations to journal articles in most subjects is to use one of the two major citation indexes, Web of Science and Scopus. ...

  A caution about Google Scholar: ... For non-scientific subjects, it is especially dicey. Many journals, additionally, do not permit Google Scholar to list their articles. ... In the other direction, GS includes sources that are not peer-reviewed, such as academic web sites and other self-published sources.[2] It has also been criticized for not vetting journals and including predatory journals.[3] Thus, the number of citations found there can sometimes be significantly more than the number of actual citations from truly reliable scholarly material. In essence, it is a rough guide only.

  If you can find multiple peer-reviewed academic reviews of multiple of her solo-authored books, that would be more helpful for a NAUTHOR pass.

  Amazing numbers for a women in science, I should think, is staggeringly sexist and patronizing. Just wow. JoelleJay (talk) 14:06, 10 August 2026 (UTC)

  I'm very aware that Wikipedia sets the bar higher for female academics than male academics. I think 'multiple peer-reviewed academic reviews of multiple books' is a bar that would rule out most academics. And, as per Wikipedia:NPROF, Google Scholar as prone to undercounting as overcounting, and can be used as a rough guide. Google Scholar is particularly compromised in this case because she doesn't have an account, which would have been helpful. That said, the top 5 results do seem to be the right M Emery, and have between 115 and 274 citations each, according to Google Scholar. The only journal among those five results is Systemic Practice and Action Research, which has an impact factor of 1.8. Springer report 56 and 35 citations for those two articles, about 1/3 of what Google Scholar reports. I suspect the truth is somewhere in between. Looking through Google Scholar, a lot of those citations come from the same two journals, Systems Research and Behavioral Science and Systemic Practice and Action Research, which possibly suggests significant impact but only in a very small field. All up, it's not nothing, this is not a field I'm familiar with, and it's tricky to compare impact factors between different disciplines. But. Compared to what I'm used to, and considering that this is over 20+ years, I can't build an argument for notability on citations. On the other hand, you could say much the same about Fred Emery's citation record if you only rely on Scopus Preview - it (wrongly) rates his h-number as being lower than hers. Citation count isn't everything. Her contribution to Open systems theory does seem significant. But is OST significant? I'm unsure that it demonstrably is. If we could quantify her contribution to Participative Design Workshop, that might be sufficient. Can we? Ben Aveling 22:26, 10 August 2026 (UTC)

  I think we can. She has not only worked on theory and done action research, but she has also helped numerous companies in Australia and Canada, in particular, in their transition to self-managing organisations. The PDW is one area where her contributions have been substantial, the other being the Search Conferences that have been the topic of her most well-known book and have been used a lot around the world, even here in Norway. It has also inspired other techniques like Weisbord's Future Search (https://futuresearch.net/about/history/).

  Generally, I think C7 should be an equally important criterion for keeping as C1. Documented applications of Emery's methods include large-scale regional planning by the U.S. Forest Service (Alvarez & Emery, SPAR 13(5), 2000); Project Australia national consultations; Torres Strait Islands community planning (Paton & Emery, Journal for Quality and Participation 19(5), 1996); and workplace mental health (de Guerre, Emery, Aughton & Trull, SPAR 21(8), 2008). NPROF is disjunctive. Trond Hjorteland (talk) 05:17, 11 August 2026 (UTC)

  Multiple empirical studies have determined Wikipedia does not set a higher bar for women academics (a recent study even found the opposite for women biologists). This is something I have also noticed across the NPROF AfDs where I have calculated the subject's senior coauthors' citation metrics to estimate the field medians.

  Yes, "multiple peer-reviewed academic reviews of multiple books" is supposed to rule out the vast majority of academics, because articles should be about highly impactful scholars and not the average professor. However, if Emery's books are as influential as claimed, it is likely that sufficient reviews exist and searching for those would be the best use of keep !voters' time.

  The problem with the GS citations, as noted at NPROF, is that they are inflated by citations in non-academic or non-indexed/non-RS academic sources.

  In my experience, trying to evaluate the impact of the subject's contributions to a topic, and the significance of the topic itself, in the absence of reliable citation counts is very difficult and rarely attempted at AfD. Fred Emery likely has escaped deletion attention due to his apparent pass of ANYBIO #2, although given he worked at the university that prepared his biography I don't think that should be given much consideration. JoelleJay (talk) 11:06, 11 August 2026 (UTC)

• Keep: Just got word that the Australian National University is preparing a biographical piece for publication on their website. Ought to be a decent sign of the importance of her work.

Trond Hjorteland (talk) 15:57, 9 August 2026 (UTC)

Under what policy would a possible piece like this warrant a keep? This is WP:CRYSTAL at best. Sulfurboy (talk) 18:42, 9 August 2026 (UTC)

ANU is definitely not an independent source, so such a piece would not be acceptable as GNG coverage. JoelleJay (talk) 14:33, 10 August 2026 (UTC)

• Keep but rewrite to make clearer her own contributions, rather than leading by saying she is known for working with someone else. It's hard to be sure what her h-index would be, but FWIW, it's going to be more than 7. See https://scholar.google.com/scholar?q=Merrelyn+Emery Ben Aveling 20:51, 9 August 2026 (UTC)
• An extra point I would like to bring up concerns the suggestion to use WP:REDIRECT to Fred Emery (psychologist). It calls for targets that contain the information sought. Fred Emery's article does not document Merrelyn Emery's independent contributions — the two-stage model of active adaptation, her work on Participative Design for Participative Democracy (1993), the Search Conference monograph (Searching, John Benjamins, 1999), or the statistical methods (Alvarez & Emery, SPAR 13(5), 2000). A redirect would leave readers at a target that does not contain the material. Also, a redirect to Fred Emery here would fit a pattern noted in Wikipedia's coverage of women in science — redirecting the woman scholar to her male partner's article rather than maintaining a standalone biography. This concern is especially relevant where the target article does not contain the redirected subject's independent contributions. Trond Hjorteland (talk) 07:42, 11 August 2026 (UTC)

  OK, if that link had been in the edit summary I might have held on the AfD. Plasma Gun Nut will have to both edit the page to improve it, and indicate why this page should survive when there are already pages such as Plasma weapon, Plasma railgun, MARAUDER, Electrothermal-chemical technology (and several SciFi pages). I am willing to listen. Ldm1954 (talk) 03:04, 6 August 2026 (UTC)

Keep Hello it's me, the user who requested undeletion. Sorry for poor communication, I am new to Wikipedia and not familiar with all the etiquette, but I will try my best.

As I also acknowledged in my undeletion request, the article is indeed in a very poor state right now, starting with the name, which in my view should be "electro-thermal gun" or something similar, as that is the most commonly used name in the scientific and technical literature on the subject. "Cannon" would refer to large-caliber versions and "plasma-powered" is a functionally descriptive name, but is not commonly encountered in the literature, but it does feature in amateur project descriptions like this one so I think keeping the link to the old name intact is useful for some audiences.

Given the issue with the name, I would Move the article, but I don't have the ability to do that yet since my account is so new.

As for noteworthyness, I think the strongest argument is that the DDTC considers the technology important enough to explicitly regulate it under ITAR category II paragraph (d) by name. If electro-thermal guns were "fringe science", as @Swatjester fears, why would the government bother regulating the technology?

If the article is kept, I will rework it to try and build out a proper timeline of the development of the technology and reference it with peer-reviewed scientific papers on the subject such as these two ([1],[2]) and technical references such as the General Dynamics and Rheinmetall patents.

Thanks for tagging me @Graeme Bartlett! Plasma Gun Nut (talk) 09:10, 6 August 2026 (UTC)

Ah, what I forgot to argue: The technology is functionally dissimilar from railguns such as MARAUDER, not having rails. It is also dissimilar from DEWs included under Plasma Cannon, as it doesn't fire plasma, only using it as a working medium. It sits somewhere between Railguns, having the electric power supply in common with them and ETC guns, sharing the gun bore with plasma injector/generator with them, but without the chemical energy supply. Plasma Gun Nut (talk) 09:28, 6 August 2026 (UTC)

@Plasma Gun Nut, if I understand your comment correctly, your approach would fall under what we call WP:TNT, i.e. Blow it up and start again with a different name. There is nothing magic about existing articles, and a lot can be said for not keeping poor ones.

Creating a new article or a major rewrite and expansion of an old one is not simple, particularly if you are not used to Wikipedia. For instance, that the DDTC page you cite mentions "plasma" once in IIe is not an extensive enough discussion to pass the Wikipedia notability criteria. It is worth reading WP:VNOTT and WP:42. These are policies decided by debates involving hundreds of editors over the years.

I think it would be a good idea for you to draft a new page using your WP:Sandbox. I suspect this will take you weeks. Most of the other editors on this page are very busy, so may not be able to help you. I don't know the topic enough to write, but would be willing to comment on your draft if you ping me. Once it is in good enough shape you could either submit it via WP:AfC (and ping the people here in case they will review it), or maybe move it to main if you have done some useful edits on other pages.

If you can rewrite the existing page in a few days then it would not be deleted using what is called the WP:HEY exception. I suspect this may be very hard to do. Ldm1954 (talk) 11:55, 6 August 2026 (UTC)

Ok, thanks for your reply, I have read the relevant guidelines on notability now. Sorry for wasting your time, but I have one more question. Do you think a review/summary of the technical progress like this could count as secondary literature? I don't think the technology has been discussed much outside of technical circles except in amateur projects. Other secondary literature in the form of summaries and reports exist, like this, but they often mix electrothermal (ET) and other technologies, including electromagnetic (EM) and electrothermal-chemical (ETC) together.

Re: timeline. I think I could write a passable article over the weekend but yeah, it's questionable whether that's worth it especially if I don't end up including much of the existing article. Another option is to write a seperate chapter in the ETC page, since they are related and historically connected to the point that the american literature doesn't always seperate them cleanly. Plasma Gun Nut (talk) 14:35, 6 August 2026 (UTC)

Neither is really a good secondary source. The way I judged that is by looking at both how many times they were cited, and how many references they had. From what I can see the first has been cited twice, the second once. Neither really indicates that the topic is notable. I went a little further and did a search using Web of Science. I found DOI 10.1109/20.559970 but that has only been cited 30 times and has 6 references, neither of which are good numbers. (I had a look at the Electrothermal-chemical technology page and the references there are also not that great for demonstrating notability.)

Sorry, but I think you need to do much more digging to find well-cited reviews which have many references and can act as secondary sources. Ldm1954 (talk) 16:05, 6 August 2026 (UTC)

Hm, okay. Maybe the notability hurdle is higher than what the topic can meet. Plasma Gun Nut (talk) 11:55, 8 August 2026 (UTC)

Sources do not show that the subject is notable. Most of the sources either do not mention the DFR or are from the DFR's website. The only reliable source here as far as I can tell is the article from The New Times. The only other source that might be reliable here is the one from ruhrkultour.de but I cannot figure out what it actually is, but it appears to be not mentioned in any reliable independent sources, so I suspect ruhrkultour.de is not a reliable source.

For a topic to be notable, there must be multiple reliable, secondary, and independent sources that give in-depth coverage of the subject. This article only shows the existence of one such source (the one from The New Times). Can you provide more such sources?

  Oppose - The word 'code' implies symbols. Assigning a numeric value to the symbols is a subset of language. A character device is the foundation of computing which implies linguistic symbols that may or may not have numerical values but need to be read and written. Unbounded code also imply unbounded set of symbols. Base 10 or base 26 or base 256 can result in a limited code set that cannot accommodate multiple languages. 97d07dad-8ddb-4b7a-ab17-f4d4e7ca376f (talk) 13:34, 1 August 2026 (UTC)

• Oppose. The use of a trailing 0 in unary coding makes it have significantly different properties, in terms of coding theory, from unary numerals. In particular, unary coding forms a prefix code but unary numerals do not form a valid code at all. —David Eppstein (talk) 21:42, 30 July 2026 (UTC)

Hurricane Brenda (1973)

I propose merging to 1973 Atlantic hurricane season because it, along with the season's other sub-articles, are all rather short, and could be merged into the season article. Check out Draft:1973 Atlantic hurricane season for what a merge would look like.

Strong Opposition to Merging: None of these pages are suitable for merger. They were each significant storms, and all are Good Article rated. They are also too long to merge without loosing major details. Your proposed omnibus article is clunky, and to include all of the information it should would need significant expansion, which would put it in violation of WP:Size. The way it is now is better for these, and other reasons. Foxtrot620 (talk) 02:21, 29 July 2026 (UTC)

How are any of these significant storms? None of them have any lasting coverage. As shown in the theoretical season article, there isn't too much detail to merge. Each of the sub-articles have a lot of preparations (which are routine), and use a lot of words to not say a lot. Even though they are good articles, that doesn't mean they can't be merged. ♫ Hurricanehink (talk) 02:30, 29 July 2026 (UTC)

Oppose merge I see what the nominator means to a point, but each of the individual pages meets the coverage standard to stand alone. The detail in the pages isn't too intricate or too passing and interested people would be served well by both the omnibus as it exists and the extra detail in the separate pages. Dizzycheekchewer (talk) 03:56, 29 July 2026 (UTC)

@Dizzycheekchewer: sorry what do you mean by "the omnibus"? Do you mean the season article? The 1973 Atlantic hurricane season is currently only 4,043 words. So the extra detail constitutes more of a content fork. ♫ Hurricanehink (talk) 05:45, 29 July 2026 (UTC)

Yeah I mean the season article. I mean that right now, the detail in the articles isn't too much or too little and a merge would, theoretically either get rid of detail that adds value and/or overburden the season article. The current divide works best, imo. Dizzycheekchewer (talk) 16:10, 29 July 2026 (UTC)

@Dizzycheekchewer: but if you see the draft for what it would look like, such a merger would not overburden the season article, it's still a reasonable size. ♫ Hurricanehink (talk) 17:00, 29 July 2026 (UTC)

Yeah I think that version loses some of the detail from e.g. the Brenda article that is a) useful and b) not overdone in that specific context. Dizzycheekchewer (talk) 17:07, 29 July 2026 (UTC)

I'm sorry to keep pushing, but what information in the Brenda article is useful that did not appear in the theoretical merged article? One of the only things I excluded was Brenda's apparent high winds and rainfall along the northern Yucatan, which is not backed up by the available sources. ♫ Hurricanehink (talk) 17:37, 29 July 2026 (UTC)

• Support Gilda | Neutral Brenda, Christine, and Delia. Except for Christine, all systems are below my personal threshold but, except for Gilda, not by a terrible amount especially for an event that happened over half a century ago. Gilda should have done something to Cuba but between the storm happening over half a century ago in another country with oppressive media restrictions and speaking another language, I do not know to get that information. ✶Quxyz✶ (talk) 10:46, 29 July 2026 (UTC)

• Even Spanish sources merely mention Gilda as having affected Cuba, but without any detail. I checked the first few pages of Google searches for [Tormenta Tropical Gilda 1973 Cuba] and didn't have any luck.

To editor Hurricanehink: Fs! they all seem notable to me, and so warrant their own, detailed articles. Merged article looks pretty good!, but is less detailed than individual articles (naturally). Would prefer if merged article only has an overview of each system, w/ a link to main article for further details, and generally don't think we've gotta worry so much abt articles' short size (as long as they're not stubs, w/c these don't seem to be to me :) - rn, would really only change !vote if any failed WP:GNG or WP:SNG, but none seem to! - Asdfjrjjj (talk) 19:40, 30 July 2026 (UTC)

• Support Merge for Christine and Gilda—Neutral for Brenda and Delia — Christine is a routine storm, easy merge. Even though Gilda seems to be a significant storm it’s extremely difficult to find information on Latin American storms outside of Mexico during this time period so it’s going to have to be a merge. Brenda and Delia may have room for expansion though, a quick search of Newspapers.com shows a good amount of results for those queries, I could look into whether those results come up with anything actually worth adding to the article but for now my stance will be Neutral for Brenda and Delia.IrishSurfer21 (talk) 18:08, 31 July 2026 (UTC)
