[1]Retiree, Research Scientist III, Cloud and Aerosol Research Group, University of Washington, Seattle (1976-2006). Co-winner in 2005 with the late Prof. Peter V. Hobbs of a monetary prize adjudicated by the World Meteorological Organization concerning our work in cloud seeding/weather modification.
Target journal: Research Integrity and Peer Review (?)
This study surveys the citing practices in the literature of cloud seeding experiments. In particular, 90 peer-reviewed journal articles that cite experiments in Colorado and Israel in that are of particular interest because both went through almost identical rise and fall cycles. Both sets of these experiments were once deemed by our highest scientific organizations and many individual scientists as ones that had proved "cloud seeding works" (e.g., National Research Council-National Academy of Sciences 1973 for the Colorado orographic experiments; Kerr (1982, Dennis 1989) and in numerous other places for the first two experiments in Israel).
But what happens in the journal peer-reviewed literature when such esteemed sets of experiments are shown to be ersatz "successes," as happened later to each set of these experiments? It will be shown in this review of those 90 peer-reviewed publications in several journals that there is an appreciable fraction of researchers who continue to cite only the successful phases of these experiments, thus demonstrating, "one-sided" citing that misled their readers. These instances, first and foremost, represent failures in the peer-review process.
It is recommended that explicit wording that condemns one-sided citing be placed in our AMS professional "guidelines[1]" The Weather Modification Association, too, should add a similar explicit wording that condemns one-sided citing in its still extant, "Code of Ethics." (The AMS eliminated its "Code of Ethics" many years ago in favor of "Guidelines.")
The purpose of citing in journal articles is to give the reader an accurate, balanced, and up to date background on the area of science being discussed, and to support various assertions in articles so that the reader can see that what is being stated has been shown to have support or needs further research. Our science ideals mandate that we do this as best we can. Selective or "one-sided citing" is defined as when an author or authors cite only one side of an issue that is multifaceted; only part of the "story" is revealed to the journal reader, the side that the authors, and by inference, the reviewers of such manuscripts, only wish them to know about.
However, in controversial domains where strong differences of opinion, vested (funding) interests and a priori beliefs (confirmation and desirability bias) abound, we may fall short of this ideal. But by how much, if any?
We answer this question by examining citations in articles that concern two sets of once highly regarded cloud seeding experiments, those conducted by Colorado State University scientists at Climax and Wolf Creek Pass, Colorado, and those conducted in Israel by scientists at the Hebrew University of Jerusalem. This test of evenhandedness in our science literature comes by examining the citations in the peer-reviewed literature one-year or more (final accepted date is used) after significant flaws were reported for these experiments to see if the reports that compromised them were also cited, presumably for the purpose of alerting the reader to the discovery of problems.
We used the "advanced search" option of the American Meteorological Society (AMS) journal web site using author names to find the articles that have been associated with these experiments. The author names used were those associated with the original reports of cloud seeding successes.
Citations in the 1986 AMS Monograph, 43, No. 21, "Precipitation Enhancement—A Scientific Challenge" were also inspected and were included if they met the search criteria.
Peer-reviewed articles in the J. Wea. Mod., published annually by the Weather Modification Association (WMA) were also examined. The non-peer reviewed articles within that journal were ignored.
The Isr. J. of Earth Sci.was also examined from 1980 through 2011 when the journal discontinued publishing. Two articles were found that met the citing criteria.
Search year initializations for the experiments: For the Climax and Wolf Creek Pass experiments in Colorado, compromising literature began to appear with Meltesen et al. (1978), Rangno (1979a, b) Hobbs and Rangno (1979a, b), and Mielke (1979). Therefore, our scrutiny of citing practices in peer-reviewed cloud seeding articles for these experiments begins in 1980.
For the Israeli experiments, the first flaw casting doubt on seeding efficacy was reported in January 1988 (Rangno) concerning the clouds of Israel, and was followed by Gabriel and Rosenfeld (1990) who reported a null statistical result for the "full" Israel-2 crossover experiment. The a priori designed crossover result of this experiment (Silverman 2001), completed in 1975, had not been previously reported. The scrutiny of the citations regarding these two experiments, Israel-1 and 2, therefore begins in 1989.
In essence, the null hypothesis of this survey based on the ideals of science is that there will be no differences in citation practices following the appearance of the compromising literature; i. e., both the flaws in these sets of experiments and the successful phases will be reported in the articles that cite them after the starting dates above to give the reader a full view of what happened to them.
If only the "success" phase of the Colorado and/or Israeli experiments have been cited in a journal article after the dates that compromising literature appeared, that publication is deemed as having exhibited, "selective" or "one-sided" citing (Schultz 2009).
Conference preprints or "grey" literature, such as "Final Reports," are included in this study if they provided key information that was not published elsewhere, such as ice particle concentrations vs. cloud top temperature (e.g., Grant 1968, Vardiman and Hartzell 1976, Grant et al. 1982). These types of literature appear in a blue font with a gray background in the references. They often revealed problems in these experiments that did not reach the peer-reviewed literature. Many "grey literature" reports that were cited in journal publications were not available for this purpose.
This survey, in effect, also answers the question, "How exactly does the scientific community react to those who tear down established scientific consensuses rather than building them up?" "Are they welcomed or shunned?", despite our ideals that mandate us to tell the 'full story' to journal readers.
2. Defining contrary or compromising literature
In one type of literature that can be regarded as "contrary" or "adverse" to a cloud seeding success are cloud reports that go counter to the reports of the experimenters who often reported lower ice particle concentrations in the natural clouds. That is, they described clouds that were ripe for seeding that explained a result where seeding had appeared to increase precipitation. When literature appears that contradicts the "ripe for seeding" reports, that in fact, the clouds that were targeted had much higher natural ice particle concentrations, these later findings are considered "adverse" or "contrary" literature. Findings like the latter cast doubt that a claimed statistically significant success due to seeding actually happened. Assertions by the experimenters that cloud top temperatures indexed ice particle concentrations are also assayed and if found unreliable in later research, the later findings are also considered "adverse" to the original reports.
Both the Colorado and Israeli experiments suffered from these kinds of "adverse" cloud seeding literature where the true nature of the clouds in each locale does not support the idea that significant increases in precipitation could have been produced by cloud seeding.
The most obvious "contrary" literature is that where a reanalysis of the original experiments has taken place that demonstrates that a natural distribution of storms ("storm types") on seeded days created the misperception of seeding effects or a Type I statistical error (e. g., Neyman 1977). For maximum credibility, however, re-analyses should not be wide searches through many variables (i.e, "fishing expeditions") but far simpler; those that expand the original reports to regional views using the same data and experimental dates as did the experimenters. This type of analysis is one that should have been conducted by the original experimenters in the first place, but is often overlooked as they focused on small target areas, as in the Climax and Wolf Creek Pass experiments in Colorado (e.g., Mielke et al. 1970, Morel-Seytoux and Saheli 1973).
Ninety peer-reviewed cloud seeding articles referenced the two benchmark sets of experiments after the dates that compromising literature began to appear in journals or in "grey" literature. Of the 90 peer-reviewed articles examined, 38, or 42% did not cite literature that compromised the successful phase of the experiments in Colorado or Israel; they only cited the successful phase for the reader. These 38 articles are deemed to have exhibited "one-sided" or "selective" citing.
Twenty-five of 75 articles, or 33%, that exhibited one-sided citing were in American Meteorological Society publications. Twelve of 13 articles in the peer-reviewed segment of the J. Wea. Mod. exhibited "one-sided" citing, or 92%, of those articles that cited the Israeli or Colorado experiments only cited the successful phase.
The three peer-reviewed articles not under the AMS "tent" or in the JWMA, one in Atmos. Res., and two in the other journal, Israel J. Earth Sci., did not exhibit one-sided citing but gave the reader a second view.
The NRC-NAS 2003 volume, "Critical Issues in Weather Modification," was also reviewed for citing balance, and was found to be skewed toward leaving out important references to publications that compromised those experiments that they had deemed successful in their prior review in 1973. The NRC-NAS 2003 review does not compare in depth to that of the 1973 review. A total of 18 relevant cloud seeding reports or peer-reviewed publications went uncited in this volume (abbreviations of those: Abbreviations (see Appendix 3) of extant adverse literature that went uncited in the NRC-NAS volume: Fur67, AVM69, VGr72a, b, V74, VH76, V78, R79, HR79, Rh83, R86, RoG89, L92, L94, LGG96, LKR97, RH97a, b, ROS98.
For those few wishing to go farther, a comprehensive review of the NRC-NAS 2003 document by the present writer can be found here.

The articles examined for citing tendencies are listed Tables below the reference section. Table 1 is for AMS publications, including the AMS monograph on cloud seeding, and other journals, including a list of citations within NRC-NAS, "Critical Issues in Weather Modification Research." Table 2 is for those articles in the J. Wea. Mod. A key to the many abbreviations of relevant literature cited in each article that met the search criteria is found in Table 3.
The table linked to below is a list of those authors that led or participated in one-sided citing and their institutions. In cases where the author name appears once, it was probably a "peccadillo" due to careless citing or possibly ignorance of the full literature on the experiments in Colorado and Israel. Where an author's name appears repeatedly, it can be surmised that there was an agenda that meant included not informing readers of the full story, thus misleading them.
https://cloud-maven.com/wp-content/uploads/2022/01/One-sided-authors.pdf
Two examples of omitted literature.
Breed et al. (2014) in the context of the National Center for Atmospheric Research's (NCAR) involvement in cloud seeding in Wyoming, mention the Climax randomized experiments by only citing a single publication, Mielke et al. (1981). In Mielke et al. (1981), the journal reader will find the story of a robust cloud seeding success. Breed et al. (2014) deflected the reader from the voluminous contrary journal trail that preceded and followed Mielke et al. (1981), a trail that began with Meltesen et al. (1978), Hobbs and Rangno (1979), Mielke 1979, Rhea (1983) and several more re-analyses and commentaries (Rangno and Hobbs 1987; 1993; 1995, Rangno (2000).
Hobbs and Rangno (1979a, b) found that the underlying physical foundations for a seeding success at Climax, the stratifications of experimental days by 500 mb temperatures, claimed to have had cloud microstructure implications, was unreliable, as did several other researchers, including Mielke (1979), Cooper and Saunders (1980).
This contrary literature goes uncited by Breed et al. (2014). Why? Was it because the authors wished their journal readers to view only one side of the Climax literature to convince readers that a cloud seeding success had been attained in the Rockies? This as the State of Wyoming inexplicably considers cloud seeding after the sophisticated Wyoming randomized orographic cloud seeding experiment, designed and evaluated by the National Center for Atmospheric Research, "failed to deliver" (they got a null result after six seasons of winter seeding).
In fact, the Climax experiments have no remaining credibility as having produced reliable evidence of increases in snowfall due to seeding, as a read of the abundant contrary literature listed above will show. Thus, the single citation to Mielke et al (1981) by Breed et al. was tantamount to solely citing Fleishmann and Pons (1989) as evidence of "cold fusion."
Another example of omitted contrary literature was seen in in Freud et al. (2015—hereafter, F15) study of Israeli clouds. F15 discovered the high precipitating efficiency of Israeli clouds 27 years after Rangno (1988) and Levin (1992, 1994) deduced the same ready formation of precipitation in Israeli clouds. But F15 does not cite that 1988 breakthrough paper.
F15 also cite Givati and Rosenfeld (2005) who asserted that Israeli operational seeding-induced increases in rain were completely masked by air pollution. But F15 did not cite those articles by Kessler et al. (2006), Alpert et al 2008; Halfon et al. 2009; Levin (2009); Ayers and Levin (2009), all of whom reviewed the Givati and Rosenfeld claims and found them unconvincing.
The final arbiter for this dispute was the Israeli National Water Authority that also found the pollution claims of Givati and Rosenfeld unconvincing after weighing all the evidence. Operational seeding of the Lake Kinneret (Sea of Galilee) watershed was therefore terminated in 2007 (Sharon et al. 2008).
5. Discussion.
One-sided, or selective citing in our journal literature has been demonstrated as a frequently occurring phenomenon in the cloud seeding literature. From a standpoint of our ideals of science, it should never occur. Readers should never be misled. One-sided citing can be seen as having been encompassed by the Federal Trade Commission's statement on consumer fraud, adjusted below for the science reader:
"Certain elements undergird all deception cases. First, there must be a representation, omissionor practice that is likely to mislead the consumer [journal reader]."
To mislead, to truncate truth, as one-sided citing is, by any reasonable definition, a form of "scientific misconduct." It is, alternately, to use the phrasing of the NRC-NAS (e.g., 1995, 2009), "cooking and trimming" the truth. One-sided citing, to this author, is the same as eliminating a data point.
The issue of one-sided citing has been called out by Schultz (2009): "One-sided reviews of the literature that ignore alternative points of view, however, can be easily recognized by the audience, leading to discrediting of your work as being biased and offending neglected authors…"
Not surprisingly, selective citing has been noted in other science domains (Urlings et al. 2019).
The damage caused by one-sided citing is not just to authors who are seen as biased, it also causes material damage to authors whose work goes inappropriately uncited; they may lose ground in promotions, awards, and without doubt, in the perceived impact that his/her work has had on his/her field since impact is measured by citation metrics. From the Council of Science Editors:
"Most metrics of scholarly performance, including the Journal Impact Factor (JIF), are based on citations to published articles."
The less you are cited, the less impact you are perceived to have had in your field.
The question for us then becomes, "Is it OK to have even just a single one-sided reference to one side of the 'coin' in our journal articles?"
We think not.
It was also clear that even though there was an abundance of contrary literature, the successful phase citations to cloud seeding experiments far outweighed the citations to contrary literature. It was also observed that some (unnamed) authors never refer to compromising literature suggesting personal agendas.
5. The institutional and co-author ramifications of one-sided citing
It can be argued that authors who practice one-sided citing damage their own institutions. Authors who have performed "one-sided citing" have been associated with such highly regarded institutions such as the National Center for Atmospheric Research, and the Hebrew University of Jerusalem. Those authors have shown little regard for the implicit damage done to their home institutions by "easily recognized" one-sided citing. Moreover, responsibility for such acts is shared among of all the co-authors who are co-authors of publications that contain this act.
What one-sided citing says about peer-review.
One-sided citing is also an "LED signpost" of inadequate peer-review of manuscripts. Reviews by knowledgeable, objectivereviewers would never allow one-sided citing to take place in manuscripts destined for publication. This could only happen if journal editors assigned reviews to those ignorant of the full body of literature that a manuscript addresses, or to seeding partisans that allow one-sided citing to reach journals. The J. Wea. Mod. results are particularly suggestive of editor/reviewer bias.
Inadequate or partisan reviews have cost the public and our science cloud community much pain over the entire history of weather modification as long-time observers know. The nation's most costly randomized orographic experiment, the Colorado River Basin Pilot Project, 1970-75, was based on prior, published cloud seeding "successes" that never happened in the first place. But those ersatz reports of successes got into our peer-reviewed literature anyway and convinced our best scientists that they were successes due to weak reviews of manuscripts.
The sad aspect of these one-sided journal articles is that a single sentence or even a footnote following the report of the original "success" stating, "These results have been questioned or overturned", followed by a reference or two, would have made this survey unnecessary. The recent review of orographic cloud seeding by Rauber et al. (2019) fulfills this simple requirement.
What to do about one-sided citing?
Explicit wording that condemns one-sided citing is required in our AMS professional "guidelines[1]" The Weather Modification Association, too, should add a similar explicit wording that condemns one-sided citing in its still extant, "Code of Ethics."
Integrating the language of the FTC quoted above at the beginning of this essay (with the applicable word changes) into our AMS "Code of Ethics" would be the responsible course to follow to stop what could be seen as fraudulent acts (no matter how minor they might seem) that mislead readers to false conclusions and harms uncited researchers. Moreover, such acts denigrate the institutions from which "one-sided citing" emanates.
[1]Also, restore the original AMS label for our professional responsibilities, our stronger label, "Code of Ethics" from the current, mere, "Guidelines" label.
We have shown that there is a credibility "inertia" that is not easily reversed; that the authors of numerous cloud seeding papers ignored contrary evidence concerning the successful phase of cloud seeding experiments they cited; nearly all of these adverse reports were in the same journal that they themselves had published one-sided articles in.
One can also posit a strong argument that "one-sided" or "selective" citing that gives only one side of the "coin" should never appear in a peer-reviewed journal. But authors who are not aware of the full body of literature, or have agendas can't be completely blamed; the reviewers of those 38 articles exhibiting one-sided citing were also unfit to review the articles that they did, or also had agendas in allowing only one side of the story to be told.
While the reasons that authors frequently snub publications that overturn prior work may not be exactly known, it is has been shown that "one-sided citing" exists (some might say is "rampant") in the cloud seeding literature.

APPENDIX 1. PEER-REVIEWED PUBLICATIONS IN JOURNALS UNDER THE AUSPICES OF THE AMERICAN METEOROLOGICAL SOCIETY, IN THE JOURNALS ATMOSPHERIC RESEARCH (ELSEVIER), AND THE ISRAEL JOURNAL OF EARTH SCIENCES THAT WERE EXAMINED IN THIS CITATION SURVEY .
The list of the peer-reviewed cloud seeding papers examined for "one-sided" citing concerning experiments in Colorado and Israel. The papers are confined to those that cited the cloud seeding experiments that were accepted for publication at least one year afterthe appearance of adverse literature had appeared. A reference in a red font indicates a paper that only cited the successful phase of these experiments and ignored the adverse literature (namely, the authors practiced one-sided citing). At the end of each article that met these referencing criteria, the papers cited in them that indicated a cloud seeding success are abbreviated in red. Articles that cited both the successful phase and adverse literature of these experiments are in a black font. Adverse literature also includes cloud reports at odds with those by the experimenters that provided a foundation for beliefs that cloud seeding had been successful. These supporting early cloud reports by the original experimenters generally indicated lower than actual ice particle concentrations in the seeded clouds compared to later independent measurements.
Appendix 2 lists those 13 peer-reviewed publications from the J. Wea. Mod. that were examined.
Appendix 3 is a key to the abbreviations used at the end of each journal article in Appendices 1 and 2 for the seeding success and adverse literature that was contained in them, if any.

VSU geologists know the secret of turning reclaimed waste into strategically important materials
A unique technology of recycling reclaimed waste capable of solving a number of environmental problems has been invented by scientists from the Faculty of Geology of Voronezh State University.
The project of VSU geologists under the leadership of Viktor Nenakhov, the Dean of the Faculty of Geology and the Head of the Department of General Geology and Geodynamics, "The technology of recycling screenings at the Pavlovsk mining and processing works aimed at increasing their market demand and reducing environmental damage" has taken second prize in the contest of Innovation projects of Voronezh State University in 2014–15. The project's author is Dmitry Shevtsov, a postgraduate student at the Department of General Geology and Geodynamics.
The scientists have focused their research on waste material consisting of stone screening dust that has formed as a result of the Pavlovsk mining and processing works. VSU geologists studied its mineral composition and used the data to develop a new innovative technology for its recycling.
'At present the amount of accumulated stone screening dust is about 30 million tonnes. It is made up of granite crush less than 5 millimetres in size. What's more, about one million tonne of stone screening dust is produced annually which has an enormous environmental impact. We started our recycling project to mitigate such impact,' said Dmitry Shevtsov.
The recycling technology developed by the VSU scientists is based on distributing the screenings into 3 fractions depending on the size of particles: the first fraction is from 5 to 2.5 mm in size, the second – from 2.5 to 0.2 mm and the third – 0.2 and smaller. The first and the second fractions can be used as the final product.
The first fraction is mainly used as a filler in asphalt. Considering the amount of road works in the region and the country as a whole this product has an extensive market. Additionally, the demand for the product increases considerably between October and April as it is used in dealing with icy conditions. One of the advanced applications of the fraction is in roofing, which can be explained by the development of wooden house building. Another application of the fraction is man-made stone production.
'The second fraction is of interest to producers of reinforced concrete products which traditionally use glass sand as a filler. The experts believe that the sand manufactured using the second fraction has better physical and mechanical properties (with 40% increase in rigidity), it also has a better hardening rate,' says the project's author. 'Vibropress product manufacturers (paving slabs, road kerbs, etc.) and dry building mix manufacturers (sand-cement plaster facade mixes, poured flooring, tile grouts, and tile adhesives) have also have shown a lot of interest in this type of fraction.
The third fraction is the most valuable component of the screening. It includes such minerals as black iron ore, titanic iron ore, rutile and zircon. Titanic iron ore and rutile are materials that are in high demand by manufacturers of titanium sponge and titanium white. Titanium sponge is used in the chemical and metallurgy industries and is a strategic material. Titanium white is mainly used in paint production. Today it is mostly imported. For example, titanium white for the Semiluki varnish and lacquer plant is imported from China. Many plants receive ilmenite concentrate from Ukraine and Australia. Zircon concentrate is of very high value; its price on the world market is about 2–3 thousand dollars per tonne. The Nuclear industry and rocket and missile engineering are based on zircon processing end products. The third component of the fraction is the highly prized black iron ore which is used in iron metallurgy and the electrochemical industry. To ensure waste free production the remains of the third fraction can be used to produce slag wool.
At a rough estimate, the value of screening supplies stored by the company is about 50 billion roubles.'
'Heavy minerals are strategically important materials,' says Dmitry Shevtsov. 'For example, zircon mining in Russia amounts to about 5 thousand tonnes annually. However, there is a much larger demand for it – about 150 thousand tonnes annually and by 2020 it will have reached about 600 thousand tonnes annually. The lack of material has to be compensated for by imports.
This means that the project has great potential in the context of the present foreign trade difficulties. Full-scale introduction of this innovative technology will contribute to solving a number of environmental problems by means of reducing waste production, and reduce the shortage of strategically important materials requiring import. High-level processing of each screening component ensures very high profitability of the developed innovative technology. The fact that the technology can be used not only at the Pavlovsk mining and processing works but at other production facilities is also of great importance.

Some identity related terms to remember are as follows.
Identity – It is the means by which a user, device, or, code (entity) is identified as unique.
Identifier – This is another term, related to identity, referring the means by which the identity is asserted.
Another identity-related term is entity. It refers to types which have an identity, to users, devices, codes.
Entitlement – The process of managing privileges to identities and related attributes.
Federation is the term used for the connection between one identity repository to another. The term, persona, is identity plus attribute that provide context to the environment the entity is operating within.
Attributes – They are facets of an identity.
In this slide, we will get introduced to identity in cloud environment. With industries scaling from small scale to global levels with different types cloud deployment models, identity management has become a major issue.
In cloud, using an identity for all entities is considered as a decision to mitigate risk and improve the security aspects of the cloud systems.
While implementing identity for cloud deployment, some factors have to be taken into consideration. One factor is the strength with which an identity can be asserted. Another factor is the strength with which an attribute can be asserted. The third factor is the instances during which a transient identity is sufficient. Last factor is the instances where pseudo-anonymity is needed.
In the next slide we will learn about identity architecture for cloud.
Federation is basically the use of SAML (pronounced as S-A-M-L) or security assertion markup language for offering portability to varied security domains. By means of a federated gateway, organizations extend their DS environment to SAML assertions. There are other organizations, which consume SAML assertions from an identity service.
Federation standards are widely used in SaaS for the purpose of identity federation and access control. However, there are no equivalent standards for IaaS/PaaS. Organizations that use Privileged Identity Management (PIL) tools (tools used for managing identity of privileged users within an organization or outside) should explore their usage in cloud environment as well.

Actress Jane Sibbett played a lesbian on 'Friends.' The part turned her life upside down.

Jane Sibbett (right) with Jessica Hecht on 'Friends'
"It became apparent soon after [beginning to play Carol] there was suddenly a responsibility about being able to stand up against all of the people that were saying this was wrong, including my own father who had a really hard time with that. I was going toe to toe with people on talk shows in America, who were saying, you know, this and this and this is the reason why you shouldn't be doing this. I would have to break things down for them. And I felt like it was really important for me to be super clear; love is the most important, of all the things that we could possibly do love is the most important way forward from anybody. So, that was my biggest responsibility, to make sure that people knew that."—Friends regular Jane Sibbett, telling Now To Love how playing a lesbian character on the show invited unexpected backlash. Friends came under fire at the time for including a recurring lesbian couple on the series. The show has endured criticism in recent years for tone-deaf humor around LGBTQ characters.

Thanks Jane!!! Again, I think all that was done on Friends was done in love and humor. Even rewatching it I am not offended.
