Global Publication Trends and Research Hotspots of The Gastric Neuroendocrine Neoplasms: A Bibliometric Analysis of The Current Situation

Objective: Gastric neuroendocrine neoplasms (gNENs) are uncommon tumors, with growing understandings about the disease. Bibliometric analyzes have the advantage of visually depicting the dynamic evaluation of scientific knowledge of a specific topic. The aim of this study was to perform and report bibliometric analysis of gNENs, which was not formerly studied in the literature. Methods: Articles published between 1980 and 2022 within the database of Web of Science Core Collection were included in this bibliometric analysis. Vosviewer package program and Datawrapper were used for bibliometric data interpretation. Results: A total of 2270 articles about gNENs was detected with 63240 citations and an H index of 103. A remarkable increase was detected among the articles for years. Research have focused on gastroenterology and hepatology, endocrinology and metabolism, oncology, general medicine, pathology and surgery areas. Norwegian University of Science Technology was the leading institution about gNENs literature. Modlin IM, had the highest number of articles and citations among the authors. United States, Japan and Italy were the top three countries with the most published articles. Conclusion: This bibliometric study provides an engrossing, insightful conclusion to the research and development trajectory in gNENs with a future perspective.

Rate of Advancement of Detection Limits in Mass Spectrometry: Is there a Moore's Law of Mass Spec?

Mass spectrometry is a well-established analytical technique for studying the masses of atoms, molecules, or fragments of molecules. One of the key metrics of mass spectrometers is the limit of detection e.g., the minimum amount of signal from an analyte that can be reliably distinguished from noise. Detection limits have improved greatly over the last 30-40 years to the point that nanogram per litre and even picogram per litre detections are commonly reported. There is however, a difference between detection limits obtained with a single, pure compound in a pure solvent and those obtained from real life samples/matrixes. Determining a practical detection limit for mass spectrometry is difficult because it depends on multiple factors, such as the compound under test, the matrix, data processing methods and spectrometer type. Here we show the improvements in reported limits of detection on mass spectrometers over time using industry and literature data. The limit of detection for glycine and dichlorodiphenyltrichloroethane were taken from multiple published articles spanning a period of 45 years. The limits of detection were plotted against the article's year of publication to assess whether the trend in improvement in sensitivity resembles Moore's Law of computing (essentially doubling every two years). The results show that advancements in detection limits in mass spectrometry are close to, but not quite at a rate equivalent to Moore's Law and the improvements in detection limits reported from industry seem to be greater than those reported in the academic literature.

Representing Transgender in the 1970s Australian Media

AbstractIn 1970s Australia, magazines and newspapers regularly featured stories about transgender women. The articles were often exploitative and depicted transgender people as freaks, with headlines designed to shock and mock. Digging deeper, there is another side to transgender people in the Australian media. Notwithstanding the exploitative nature of the coverage, the media was still a site of transgender visibility in an era where there otherwise was none. Oral histories with transgender Australians often mention the importance of a particular television show, article or magazine because they saw others ‘like them’, and they realised that they were not alone. Some transgender people even kept those articles for years because of the connections they felt to an otherwise uncertain identity. There were also features in the press that were empathetic to transgender Australians, whether that be on the Australian Broadcasting Commission (ABC), in magazines such as Cleo or in broadsheet newspapers. This article analyses the complex role that media played representing and relating to transgender Australians in the 1970s. Drawing on a mix of newspaper, magazine and television sources, as well as oral histories, the article opens new lines of inquiry about histories of transgender visibility, public discourse and understanding the self.

The growth of social media in science: Social media has evolved from a mere communication channel to an integral tool for discussion and research collaboration.

Social media has become popular among scientists to communicate within and beyond their communities. More specialized channels and the ongoing lockdowns further increase their value and use.

Taxonomic Notes on the 'Mahat' (Artocarpus lacucha and A. thailandicus, Moraceae) Species Complex in Thailand.

‘Mahat’ is a well-known medicinal plant utilized in Thailand. The Thai name ‘Mahat’ has been used in many scientific articles for years. However, it is, unpredictably, a homonym of two scientific names in Flora of Thailand, i.e., A. lacucha and A. thailandicus. Additionally, both species are complex due to their high morphological variation. This causes difficulties in species identification especially when this Thai name is referred to as the scientific name for research publication, quality control of pharmaceutical raw materials, and registration of pharmaceutical products. In this study, we scrutinized the taxonomy of ‘Mahat’ by detailed examination of its morphology and distribution, including molecular and qualitative phytochemical studies. Leaf surfaces were inspected using scanning electron microscopy. The phylogeny of both species was studied using DNA sequences of nuclear and plastid regions. Chromatographic fingerprints, focusing on the major active compound oxyresveratrol, were identified using high-performance liquid chromatography. According to our current study, phylogenetic evidence showed that some samples of both species were clustered together in the same clade and phytochemical fingerprints were almost identical. These results are valuable data for taxonomic revision in the near future and reveal the possible utilization of A. thailandicus as a new material source of oxyresveratrol in the pharmaceutical industry.

Coverage of Corruption News by Major Newspapers in Nigeria

This research arises from the need that conscious effort and attention is needed to curb the negative effects of corruption on socio-economic transformation of the nation and that exploiting the media to expose corrupt practices in sectors of the nation’s economy is the best way in shaping public opinions on the menace of corruption. This study used content analysis to determine the Newspaper coverage of corruption news in the major sectors of the Nigeria economy over a period of 5 years (2006 - 2010). A multi-stage sampling technique was used to select three newspapers namely Tribune, The Nation and Guardian; and a total of nine hundred and thirteen (913) corruption articles generated from the 540 issues were analysed in this study. Data were collected on frequency of coverage, categories of items/stories, prominence, space allotment and depth of treatment of articles on corruption. Descriptive statistics such as frequencies, percentages and means was used to summarise the data collected. Findings revealed that frequency of coverage of corruption articles in year 2010 carries the highest percentage of 23.7% while the Nigerian Tribune ranked first on the coverage of corruption articles with a total number of 381 (41.7%) articles. Overall, prominence was given to inside page articles (87.4%) in all the three newspapers, however, the Guardian newspaper, reported the highest in the front page having 41.7%. Majority (76.7%) of the corruption articles fell in the news category with the Nigerian Tribune having 42.4%. More than half (56.8%) of space allotted to corruption articles is one-quarter page while the Nigeria Tribune recorded highest (61.4%) space allotment of full page. The politics/governance sector ranked first with a total of 522 news items accounting for 57.2% of the whole corruption stories while agriculture, transport and energy sectors occupied the lower rung of the ladder. Also, politics/governance sector had the highest level of prominence with score of 654. Study concluded that Politics/Governance, Service oriented (i.e. telecommunications and banks), and sports sectors are perceived to be more corrupt sectors in Nigeria. Keywords: Corruption news, newspapers, coverage, Nigerian sectors.

Impact Factor, Impact, and Smoke and Mirrors

I believe that the editorial by Martin Tobin, “Thirty years of impact factor and the Journal,” which appeared in the August 15, 2004 issue of the AJRCCM, merits comment (1). I was particularly struck by the figure showing a dramatic upward trajectory in the impact factor in recent years. This, to me, bore an ominous resemblance to the increase in the NASDAQ stock index in the late 1990s, before its collapse in 2000. We, as physician-scientists, are trained to notice the unusual and to investigate further. As the author noted, the impact factor for a journal in year X is a ratio of the number of citations (in any journal) in year X to the number of articles (in the journal of interest) in years X-1 and X-2. Thus, the impact factor can be influenced by either decreasing the number of articles published or increasing the number of citations. There is evidence for both of these in the case of AJRCCM (using Thorax and Chest as reference points). Any journal can directly influence the number of articles published annually. From 1999 to 2003 the number of articles in Thorax remained stable (196 to 198) as did the number of articles in Chest (701 to 704). Over the same period of time, the number of articles published in AJRCCM decreased from 600 to 380. The trajectory for publications was increasing through 2000 when AJRCCM published 757 articles, making the 2003 number about a 50% decrease. Given the explosion of research in respiratory disease in recent years, it seems ironic that publications have been cut in half. Viewed another way, ATS members are now paying twice as much per article, which, in my mind, decreases the “impact” of the Journal. The other way to influence impact factor is to increase the number of citations to published articles. Although one would think this would primarily result from the publication of additional respected manuscripts or reviews, it is also possible with a process known as “self-citing,” which is occurring in AJRCCM at a much higher rate than in other journals. For example, of the 3,948 citations to 2002 AJRCCM articles, 1,122 (30.2%) were “self-cites.” Corresponding values from Thorax and Chest were 12.1% and 11.3%, respectively. This appears to be occurring for several reasons. First, the series “Year in Review in the Blue Journal,” which exclusively cites AJRCCM articles, artificially increases the impact factor. As an example, the 6 articles in the 2004 edition of this series cited the 380 AJRCCM articles for 2003 a total of 576 times, and will influence the 2004 impact factor (2–7). Second, authors invited to resubmit articles to AJRCCM receive the following statement: “In revising your manuscript, please update your references to ensure that you discuss your work in the context of the most recent research in this area. In particular, you need to compare your references against the articles in Year in Review 2002 and 2003 accessible through the File-Cabinet icon on the Homepage of AJRCCM.” This is apparently intended to ensure increasing citation of AJRCCM work. The net result of this can be seen in Figure 1; for AJRCCM in 2003, 44% of the 2002 articles referenced were “self-citations,” compared with 19% of 2003 Thorax article references. Other strange phenomena also occur. For example, the fourth leading citer of AJRCCM articles in 2003 was the French journal Revue des Maladies Respiratoires (with the European Respiratory Journal at number three and Thorax at number five). In 2003, 32% of the Revue des Maladies Respiratoires 2002 citations were of AJRCCM articles (341/1055), with the next highest percentages being Chest and European Respiratory Journal, both at 5%. Figure 1. Distribution pattern of citations for articles published in 2003 in (A ) AJRCCM and (B ) Thorax. The solid part of the bar represents “self citations,” which comprised, in 2002, for AJRCCM 44% (1,122/2523) of the citations and for Thorax 19% (91/491) of the citations (9).

The Black Image in Film

Rollins I Introduction to Special In-Depth Section Peter C. Rollins Editor-in-Chief The Black Image in Film y \^_^/ he recent awards presented by the Academy of Motion PictureArts and Sciences ("the Oscars") were reprehended by many because black filmmakers, actors, and technicians did not receive expected recognition. Anti-semitic comments by such celebrities as Marlon Brando (on the LarryKing Show) did not advance the cause of understanding or encourage positive recognition. We have much to learn about the black image in film and television-not only in relation to past images, but how the current images are woven into the attitudes of contemporary America. In the opening essay for this section, Prof. Mark Winoker explores the background and fallout of the images in a specific film, The Green Pastures (1936). His understanding of the available myths and stereotypes, together with close reading, reveals The Green Pastures paradox-it is at once a forum for black culture and a perpetuation of anachronistic stereotypes of the state of the black church in America. The black contribution to America's fighting forces has been of great interest during the recent celebrations of our great victory in World War II. Documentaries about the Tuskeegee airmen, plus an HBO docudrama, have reminded Americans of the essential contribution of blacks to the victory. For example, we now know that, during the Battle of the Bulge, the infusion of fresh troops was essential to stopping the German offensive and, under the command of General Patton, black soldiers recorded some major accomplishments. Just this spring, those contributions were recognized by President Clinton in the presentation of Medal of Honor medals-for the first time-to black heroes. One of them came from a small Oklahoma town not far from my home. In the Fall, we will have a special "massing of the colors" ceremony to commemorate the sacrifice of Staff Sergeant Ruben Rivers, a man who fought and died at the very tip of Patton's mechanized arrow. 4 I Film & History The Black Image in Film | Special In-Depth Section Liberators (1992) was a documentary designed to honor the black contribution in WWII, but the film went beyond the facts. In her scholarly study, Pamela Calvert places the production in its 1990s context and shows how the forces at work in the pressure-cooker environment of New York City affected the work of the two collaborators. Calvert's article also reminds us of the need to have real historians-as opposed to media typesdirectly involved in the entire range of production. We of Film & History have been reminded of this need many times over the years-in articles by Patrick Griffin, Richard Raack, and Peter Rollins—but continuing violations of basic historical methodology demand scholarly whistle-blowing. At the present time, Liberators-bolh the film and the book versions-have been withdrawn from circulation by the publisher and the network involved. This action settles the immediate problem; yet the danger in all this controversy is that we lose perspective on the real issue: there are no standards in the vast wasteland of television when it comes to historical films. Too often, the need for funding and ratings dictates that drama wins out over information. A Soldier's Story(1984) is a fine, tense film which explores the story within the story for black soldiers in WWII-and at other times. During our history, minorities have often gambled on the possibility that their willingness to fight for the nation would win them recognition and acceptance. Anyone who has been in combat training or in war knows the tensions and stresses of the role; scholar Jerome Long (a US Army veteran of the Korean era) argues that the virtue of this film is its exploration of the "second front" for blacks, the humiliation of service in a military strictly segregated. Frank Capra's film The Negro Soldier (1944) puts the best possible face on the hopes of the nation and its blacks for equity, but A Soldier's Story is a more realistic portrait of the inner struggle for America's blacks in uniform. All three essays are models of research and committed scholarship; together, they...
