Global cervical cancer research: A scientometric density equalizing mapping and socioeconomic analysis

Cervical cancer has caused substantial morbidity and mortality for millions of women over the past decades. While enormous progress has been made in diagnosis, prevention and therapy, the disease is still fatal for many women—especially in low-income countries. Since no detailed studies are available on the worldwide research landscape, we here investigated the global scientific output related to this cancer type by an established protocol. The “New Quality and Quantity Indices in Science” platform assessed all relevant cervical cancer research published in the Web of Science since 1900. A detailed analysis was conducted including country-specific research productivity, indicators for scientific quality, and relation of research activity to socioeconomic and epidemiologic figures. Visualization of data was generated by the use of density equalizing map projections. Our approach identified 22,185 articles specifically related to cervical cancer. From a global viewpoint, the United States of America was the dominating country in absolute numbers, being followed by China and Japan. By contrast, the European countries Sweden, Austria, and Norway were positioned first when the research activity was related to the population number. When the scientific productivity was related to annual cervical cancer cases, Scandinavian countries (Finland #1, Sweden #4, Norway #5, Denmark #7), the Alpine countries Austria (#2) and Switzerland (#6), and the Netherlands (#3) were leading the field. Density equalizing mapping visualized that large parts of Africa and South America were almost invisible regarding the global participation in cervical cancer research. Our data documented that worldwide cervical cancer research activity is continuously increasing but is imbalanced from a global viewpoint. Also, the study indicated that global and public health aspects should be strengthened in cervical carcinoma research in order to empower more countries to take part in international research activities.

Work honored by Nobel prizes clusters heavily in a few scientific fields

We aimed to assess whether Nobel prizes (widely considered the most prestigious award in science) are clustering in work done in a few specific disciplines. We mapped the key Nobel prize-related publication of each laureate awarded the Nobel Prize in Medicine, Physics, and Chemistry (1995–2017). These key papers mapped in only narrow sub-regions of a 91,726-cluster map of science created from 63 million Scopus-indexed published items. For each key Nobel paper, a median of 435 (range 0 to 88383) other Scopus-indexed items were published within one year and were more heavily cited than the Nobel paper. Of the 114 high-level domains that science can be divided into, only 36 have had a Nobel prize. Five of the 114 domains (particle physics [14%], cell biology [12.1%], atomic physics [10.9%], neuroscience [10.1%], molecular chemistry [5.3%]) have the lion’s share, accounting in total for 52.4% of the Nobel prizes. Using a more granular classification with 849 sub-domains shows that only 71 of these sub-domains (8.3%) have at least one Nobel-related paper. Similar clustering was seen when we mapped all the 40,819 Scopus-indexed publications representing the career-long output of all the Nobel laureates. In conclusion, work resulting in Nobel prizes is concentrated in a small minority of scientific disciplines.

Progress and impact of the publications of the Faculty of Medicine of Tunis: A 55 years study

BACKGROUND

Over the past few years, efforts have been made to ensure that the teachers of the Faculty of Medicine of Tunis (FMT) cite their affiliation to the FMT and the University of Tunis El Manar in addition to their hospital institutions and their research structure in their publications.

AIMS

In this study, we proposed to evaluate the FMT's membership in the publications of its teachers, to identify the different types of publications and to estimate the real number.

METHODS

In this bibliometric cross-sectional study, we retrieved the FMT publications indexed in medline/pubmed database (1964-June2019). We have chosen the keywords corresponding to the publications of group1 (referenced FMT) and group2 (referenced FMT or annexed hospital-university institutions). Next, we calculated the rate of group1 on group2 and sorted the different types of items in group2. Finally, We estimated, after randomization, the actual number of FMT publications for a 99% confidence interval (99% CI).

RESULTS

For groups 1 and 2, 1477 and 5194 publications were retrieved, respectively. The FMT membership rate averaged 28% ranging from 4% (1990-2010) to 44% (2011-2019). Of the FMT publications, 30% were free of charge and 55% were original articles. After a draw for 300 group2 publications, the estimated number of total FMT publications was between 4519 and 4934 for a 99% CI.

CONCLUSIONS

It is essential to mention its affiliation to «the Faculty of Medicine of Tunis» and to «the University of Tunis El Manar» in order to improve the visibility and ranking of our two academic institutions.

Ioannis Kardamatis (1852-1942): Pioneer of the Anti-Malaria Battle in Greece

Few scientists have contributed as much to medicine and society as Ioannis Kardamatis (1859-1942). Kardamatis was an important historical figure whose vast medical knowledge was recorded in a spectrum of medical publications, including monographs, bibliographic reviews, books, and experimental and statistical studies. His studies have been published in both Greek and foreign journals. He is most notably remembered for his contribution to the battle against malaria in Greece.

Thirty years of Tunisian publication of «case reports» in General Surgery (1989-2018)

OBJECTIVE

To describe the bibliometric profile of Tunisian "case report" publications in general surgery over the last thirty years (1989-2018).

METHODS

This is a descriptive bibliometric study on "case reports", general surgery, Tunisian affiliation, indexed in the Medline database, between January 1, 1989 and December 31, 2018. The themes of Search articles were defined by referring to their major keywords used for their indexing.

RESULTS

During 30 years of study, Medline indexed 188 papers in "General Surgery" type "case reports", signed by 80 authors in first position and 71 authors in last position, belonging to ten academic specialties and 19 professional affiliations. These papers were published by 60 journals, including the Ugandan magazine "Pan African Medical Journal", which published 23% of these "case reports" alone. The number of major indexing keywords was 299 words, mainly "Echinococcosis", "Pancreatic Cancers" and "Echinococcosis of the liver", together accounting for 18.1% of articles.

CONCLUSION

The plethora of "case reports" in Tunisian general surgery publications over the last three decades was accompanied by a preferential edition in the journal "Pan Afr Med J" and a thematic focus on hydatid cysts and cancers pancreatic. Hence the importance of strengthening the capacity of Tunisian surgeons in research methodology and scientific medical writing.

Bibliometrics of Tunisian publications on respiratory tract diseases from 2010 to 2014

AIM

To describe the bibliometric characteristics of Tunisian publications on respiratory tract diseases, during the quinquennium 2010-2014.

METHODS

This is a descriptive bibliometric study of respiratory medicine publications, indexed in "Medline", based on their MSDSs. All included articles were written by Tunisian researchers regardless of their position in the list of co-authors. The topics of the publications were explored through their "major" and "generic" keywords.

RESULTS

A total of 340 publications was captured in Medline. These articles were co- authored by 218 authors in first position and 163 in last position. They were signed by pulmonologists, in first and last position respectively in 21.5% and 22.4% of articles. The A. Mami Hospital was the major affiliation of the first authors in 19.7% of the publications. These articles were published by 138 journals including "La Tunisie Medicale" in 11.8% of cases. They were "case reports" and written in English respectively in 44.4% and 54.1% of cases. Among 639 major keywords indexing, three were dominant: «Lung Neoplasms» (Tumeurs du poumon), «Chronic Obstructive Pulmonary Disease» (Broncho-pneumopathie chronique obstructive) and «Tuberculosis, Pulmonary» (Tuberculose pulmonaire), in 13.5%, 10.3% and 7.4% of articles respectively.

CONCLUSION

Tunisian research on respiratory tract diseases has been thematically concordant with the public health needs. However, it has often been of low-level evidence and published in low-impact factor journals.

Top-100 highest-cited original articles in inflammatory bowel disease: A bibliometric analysis

OBJECTIVES

The use of citation analysis to identify the first 100 papers in inflammatory bowel disease (IBD) provides unique insights into advances in disease understanding and subsequent follow-up treatment innovations over time.

METHODS

The Thomson Reuters Web of Science database with the search terms "inflammatory bowel disease" or "Crohn disease" or "ulcerative colitis" or "colitis" was used to identify all English language full manuscripts for the study. Title, first and senior authors, institution and department of first author, journal, country of origin, year, and topic of each manuscript were analyzed.

RESULTS

The top 100 manuscripts were published between 1955 and 2013. 224,809 eligible papers were returned and the median (range) citation number was 1028.5 (719-3957). The country and year with the greatest number of publications were the USA (n = 47), and 2007 (n = 11). Gastroenterology published the highest number of papers (n = 18, 21,083 citations) and The New England Journal of Medicine had the most citations (n = 13, 25,035 citations).

CONCLUSIONS

This highly cited list of papers identifies the subjects and authors who have had the greatest impact on IBD research in the last decades, which serves as a reference for researchers and clinicians "highly citable" manuscripts.

The top 100: A review of the most cited articles in Surgery

INTRODUCTION

We performed a study of the top 100 most cited articles in the five general surgery journals with the highest impact according to Journal Citation Report.

METHODS

We selected the five journals with the highest impact in 2015: Annals of Surgery, British Journal of Surgery, JAMA Surgery, Surgery, and Journal of the American College of Surgeons. In January 2017, using the Web of Science application, we performed a search of all articles published by these journals and identified the 100 most cited articles (top 100). We evaluated the number of citations, year of publication, type of article, country and hospital of the article, area of interest and number of authors.

RESULTS

The median number of citations per top 100 paper was 490. Twenty percent of the top 100 papers have been published since 2000. Overall, 70% are original papers, 8% randomized control trials, 11% reviews, 1% meta-analyses and 11% other subtypes. There are 13% proceedings papers. Sixty-one percent are from the US. The most frequently discussed topic is hepato-pancreato-biliary surgery (33%).

CONCLUSIONS

The top 100 most cited articles tend to be original articles describing studies carried out in the US, reporting significant surgical breakthroughs. Hepato-pancreato-biliary surgery is the most common subject area. Annals of Surgery had twice as many citations as the other journals studied. The archetypal article of the Top15 most cited is an original paper published in the twentieth century, with an average of 2000 citations.

A Bibliometric Study of Authorship and Collaboration Trends Over the Past 30 Years in Four Major Musculoskeletal Science Journals

This study explored changes in bibliometric variables over the last 30 years for four major musculoskeletal science journals (BONE®), Calcified Tissue International® (CTI®), Journal of Bone and Mineral Research® (JBMR®), and Journal of Orthopaedic Research® (JOR®), with a specific focus on author gender. Bibliometric data were collected for all manuscripts in 1985 (BONE®, CTI®, JOR®), 1986 (JBMR®), 1995, 2005, and 2015; 2776 manuscripts met inclusion criteria. Manuscripts from Europe were more often published in BONE® or CTI®, while those from North America in JBMR® or JOR®. All journals demonstrated an increase over time in the number of authors (3.67-7.3), number of countries (1.1-1.4), number of institutions (1.4-3.1), and number of references (25.1-45.4). The number of manuscript pages increased (6.6-8.9) except for JOR® which showed a decline. CTI® had the lowest number of authors (4.9 vs. 5.6-6.8). There was a change in the corresponding author position from first to last for all journals; this change was highest for CTI® (35%) and lowest for BONE® (14.0%). All journals demonstrated an increase over time in female authors; however, CTI® was the highest amongst these four journals. The percentage of female first authors rose from 24.6 to 44.3% (CTI® 29.1-52.3%). The percentage of corresponding female authors rose from 17.5 to 33.6% (CTI® 22.9-40.0%). The proportion of female authors is increasing, likely reflecting the increasing number of women obtaining doctorates in science, medicine, and engineering.

The gender gap in science: How long until women are equally represented?

Women comprise a minority of the Science, Technology, Engineering, Mathematics, and Medicine (STEMM) workforce. Quantifying the gender gap may identify fields that will not reach parity without intervention, reveal underappreciated biases, and inform benchmarks for gender balance among conference speakers, editors, and hiring committees. Using the PubMed and arXiv databases, we estimated the gender of 36 million authors from >100 countries publishing in >6000 journals, covering most STEMM disciplines over the last 15 years, and made a web app allowing easy access to the data (https://lukeholman.github.io/genderGap/). Despite recent progress, the gender gap appears likely to persist for generations, particularly in surgery, computer science, physics, and maths. The gap is especially large in authorship positions associated with seniority, and prestigious journals have fewer women authors. Additionally, we estimate that men are invited by journals to submit papers at approximately double the rate of women. Wealthy countries, notably Japan, Germany, and Switzerland, had fewer women authors than poorer ones. We conclude that the STEMM gender gap will not close without further reforms in education, mentoring, and academic publishing.

In most fields of science, medicine, and technology research, men comprise more than half of the workforce, particularly at senior levels. Most previous work has concluded that the gender gap is smaller today than it was in the past, giving the impression that there will soon be equal numbers of men and women researchers and that current initiatives to recruit and retain more women are working adequately. Here, we used computational methods to determine the numbers of men and women authors listed on >10 million academic papers published since 2002, allowing us to precisely estimate the gender gap among researchers, as well as its rate of change, for most disciplines of science and medicine. We conclude that many research specialties (e.g., surgery, computer science, physics, and maths) will not reach gender parity this century, given present-day rates of increase in the number of women authors. Additionally, the gender gap varies greatly across countries, with Japan, Germany, and Switzerland having strikingly few women authors. Women were less often commissioned to write ‘invited’ papers, consistent with gender bias by journal editors, and were less often found in authorship positions usually associated with seniority (i.e., the last-listed or sole author). Our results support a need for further reforms to close the gender gap.

The 100 most influential publications in asthma from 1960 to 2017: A bibliometric analysis

BACKGROUND

The area of asthma medicine has produced a large volume of important clinical and scientific papers that can be found in those most influential journals. The purpose of our study was to identify the 100 most cited papers in asthma research and to analyze their characteristics.

METHODS

We used the Institute for Scientific Information Web of Knowledge Database to identify the most frequently cited articles published from 1960 to December 2017. Original articles and reviews were included in the study. The 100 top-cited articles were then analyzed with regard to number of citations, publication year, journals, institution, research type and field, authors and countries of authors of publications.

RESULTS

The 100 top-cited articles in asthma were published between 1960 and 2011 with a median of 933 citations per article (range, 701-2947). The number of citations per article was greatest for articles published in the 1990s. The United States of America contributed most of the classic articles, followed by England. The leading institutions were Imperial College London, McMaster University, Erasmus University Rotterdam. The 100 top-cited articles were published in twenty-five journals, led by The New England Journal of Medicine (21 articles), followed by American Journal of Respiratory and Critical Care Medicine (19 articles), Lancet (11 articles), respectively. Among the 100 classics, 50% articles were clinical research articles.

CONCLUSIONS

Our study provides a historical perspective on the progress of research on asthma. Studies conducted in well-developed European countries and North America, published in high-impact journals had the highest citations.

Trend in H₂S Biology and Medicine Research-A Bibliometric Analysis

The biological and medical importance of hydrogen sulfide (H₂S) has been recognized for decades. The aim of this bibliometric study is to analyze the quantity and quality of publications in H₂S biology and medicine (H₂SBM) based on the databases of Web of Science and Google Scholar. A total of 5881 publications published between 1990 and 2016 were analyzed. The number of H₂SBM papers published before 2004 was below 100 annually, but thereafter this number rapidly increased and peaked in 2015 with more than 7-fold increase. All publications related to H₂SBM research achieved a total h-index of 136 and were cited 123,074 times. The most published disciplines in H₂S biomedicine research were the cardiovascular system (8.5%), neuroscience (6.5%), and gastroenterology hepatology (4.7%). The country with the greatest number of publications in the H₂SBM research field was the USA with 1765 (30.0%) publications, followed by China with 995 (16.9%) publications and Japan with 555 (9.4%) publications. The top 3 most published institutes were National University of Singapore, Peking University in China, and University of Groningen in Netherlands. Nitric Oxide Biology and Chemistry was the most exploited journal for H₂SBM publications with 461 articles, followed by FASEB Journal with 200 publications and Antioxidants Redox Signaling with 116 publications. The most highly cited publications and researchers in H₂SBM research were also unmasked from this bibliometric analysis. Collectively, H₂SBM publications exhibit a continuous trend of increase, reflecting the increased H₂SBM research intensity and diversity globally.

Global research trends of World Health Organization's top eight emerging pathogens

BACKGROUND

On December 8th, 2015, World Health Organization published a priority list of eight pathogens expected to cause severe outbreaks in the near future. To better understand global research trends and characteristics of publications on these emerging pathogens, we carried out this bibliometric study hoping to contribute to global awareness and preparedness toward this topic.

METHOD

Scopus database was searched for the following pathogens/infectious diseases: Ebola, Marburg, Lassa, Rift valley, Crimean-Congo, Nipah, Middle Eastern Respiratory Syndrome (MERS), and Severe Respiratory Acute Syndrome (SARS). Retrieved articles were analyzed to obtain standard bibliometric indicators.

RESULTS

A total of 8619 journal articles were retrieved. Authors from 154 different countries contributed to publishing these articles. Two peaks of publications, an early one for SARS and a late one for Ebola, were observed. Retrieved articles received a total of 221,606 citations with a mean ± standard deviation of 25.7 ± 65.4 citations per article and an h-index of 173. International collaboration was as high as 86.9%. The Centers for Disease Control and Prevention had the highest share (344; 5.0%) followed by the University of Hong Kong with 305 (4.5%). The top leading journal was Journal of Virology with 572 (6.6%) articles while Feldmann, Heinz R. was the most productive researcher with 197 (2.3%) articles. China ranked first on SARS, Turkey ranked first on Crimean-Congo fever, while the United States of America ranked first on the remaining six diseases. Of retrieved articles, 472 (5.5%) were on vaccine - related research with Ebola vaccine being most studied.

CONCLUSION

Number of publications on studied pathogens showed sudden dramatic rise in the past two decades representing severe global outbreaks. Contribution of a large number of different countries and the relatively high h-index are indicative of how international collaboration can create common health agenda among distant different countries.

How the launch of a new journal in 1904 may have changed the relationship between psychology and philosophy

Recent research has used networks of scholarly journal articles to investigate the intellectual structure of the discipline of psychology from the later 1880s to the early 1920s. Here, instead, we examined the networks of philosophical journals that were closely aligned with psychology-The Monist, Philosophical Review, and The Journal of Philosophy, Psychology, and Scientific Methods-between 1890 and 1913. We discovered that, although the first 2 of these journals published a great deal of psychologically relevant material up to 1903, material of that sort seemed to evaporate after the launch of the third journal in 1904. It was not so much that material migrated from the old journals to the new one. It was rather that the new journal was able to attract new trends in American philosophical psychology, while interest in traditional approaches seemed to dry up. The result was that psychology moved into a new and expansive era, while America philosophy was left somewhat destabilized as it attempted to reconfigure its disciplinary identity.

Changes in Publication-Based Academic Interest in Local Anesthetics Over the Past 50 Years

PURPOSE

To present the history of changes in academic interest in local anesthetics quantitatively.

METHODS

The changes in publication-based academic interest in local anesthetics were assessed using information from the database of PubMed. The assessment was mostly based on the following indices: general popularity index (GPI), representing the proportion of articles on a drug relative to all articles in the field of regional anesthesia, and specific popularity index (SPI), representing the proportion of articles on a drug relative to all articles in one of the four forms of regional anesthesia: local anesthesia, spinal anesthesia, epidural anesthesia, and peripheral nerve blocks.

RESULTS

The most important general feature of the changes in publication-based academic interest in local anesthetics for the past 50 years was the concentration of this interest on a very limited number of drugs. By 2010-2014, only three anesthetics demonstrated the GPI value above 4.0: bupivacaine (10.1), lidocaine (10.0), and ropivacaine (4.6). All other local anesthetics had GPI declining mostly to less than 1.0 (2010-2014). The rate of change in publication-based academic interest was very slow in both its increase and decline. The most profound change in publication-based academic interests was caused by the introduction of bupivacaine. During a 20-year period (from 1965-1969 to 1985-1989), bupivacaine's GPI increased from 1.3 to 12.9.

CONCLUSION

A slowly developing concentration of publication-based academic interest on a very limited number of local anesthetics was the dominant feature related to this class of anesthetic agents.

Papers published from 1995 to 2012 by six Traditional Chinese Medicine universities in China: a bibliometric analysis based on science citation index

OBJECTIVE

The quality and quantity of published research papers are important in both scientific and technology fields. Although there are several bibliometric studies based on citation analysis, very few have focused on research related to Traditional Chinese Medicine in China.

METHODS

The bibliometric method used in this study included the following focuses: publication outputs for each year, paper type, language of publication, distribution of internationally collaborative countries, sources of funding, authorization number, distribution of institutes regarding collaborative publications, research fields, distribution of outputs in journals, citation, data, and h-index.

RESULTS

A total of 3809 papers published from 1995 to 2012 were extracted from the science citation index (SCI). The cumulative number of papers from all six universities is constantly increasing. The United States attained the dominant position regarding complementary and alternative medicine research. The Chinese Academy of Sciences was the greatest participator in collaborative efforts. Research field analysis showed that the research mainly focused on pharmacology pharmacy, chemistry, integrative complementary medicine, plant sciences, and biochemistry molecular biology. The Shanghai University of Chinese Medicine had the most citations.

CONCLUSION

In recent years, in terms of SCI papers, the six Traditional Chinese Medicine universities studied here have made great advances in scientific research.

Monoamine theories of depression: historical impact on biomedical research

Monoamine theories associate depression with reduced brain monoamine levels. These theories achieved broad popularity in the mid-1960s. The present article reviews the historical development of monoamine theories and their subsequent impact on biomedical research. Alleged divisions between West European and US researchers over competing versions of the theories are investigated using bibliometrics. Subsequently, the application of monoamine theories in the NIMH Collaborative Program on the Psychobiology of Depression is covered. The article argues that the impact of monoamine theories is best explained by the ability of researchers, governmental agencies, and pharmaceutical companies to invoke theories that advance various projects and agendas.

Medical research productivity of Lebanon: a bibliometric study of papers indexed in Medline, 1985-2004

BACKGROUND

Analysis of biomedical publications of a country is used to monitor research trends which leads to a better formulation of health policy planning and management.

AIM

We sought to describe the Lebanese medical publications productivity over a 20 years period from 1985 to 2004.

METHODS

Medline's database was consulted and the query contained the name of the country, the medical universities, the main teaching hospitals, and cities, both in French and in English. The articles with a Lebanese health affiliation were included and the articles of dentistry, veterinary, nursing and pharmacy were excluded.

RESULTS

We counted 1964 medical articles over a two-decade period. The productivity was 2,9 articles/100000 capita/year and 9,2 articles/billion US dollars GDP/year. The growth rate of publication drew a decline passing from 202% (1990-1994) to 55,3% (2000- 2004). The four most productive specialties (Anesthesiology, Internal medicine, Gynecology, Pediatrics) published 611 articles (31,1%). The governorate of Beirut, the American University of Beirut and its teaching hospital published the most with respectively 1926 (98%), 568 (28,9%), and 601 articles (30,6%).

CONCLUSION

The Lebanese medical productivity was weak and unstable mainly due to the lack of financial resources and the instability of the region. Increasing research funding, improving the physicians' research methodology and writing capacities are likely needed to improve the Lebanese medical output.

Gender analysis of papers published in ACTAS ESPANOLAS DE PSIQUIATRIA (1999-2006)

INTRODUCTION

The governments and organizations responsible for scientific policies try to encourage equality of gender, among their priorities that of obtaining equal participation and full integration of women in all aspects of the scientific profession. The study analyzes the scientific production of women in the areas of Psychiatry by means of the bibliometric study of the papers published in ACTAS ESPANOLAS DE PSIQUIATRIA.

METHOD

A total of 458 papers published from 1999- 2006 period were downloaded from the Science Citation Index-Expanded database, these including original research papers, review articles and clinical cases. A bibliometric study broken down by gender was carried out to determine the existence or inequalities between men and women regarding scientific productivity, type of document, order of author signatures, on the institutional and geographical level.

RESULTS

The papers were published by 1,194 different authors. The gender of 977 authors was identified, 587 (60.08%) men and 390 (39.92%) women. The percentage of women authorship has risen from 29.92% in 1999 to 38.86% in 2006. A total of 42.92% of authors having one published article were women, while <<the multiple article producing women>> (those with more than nine articles) only accounted for 33%.

CONCLUSION

Bibliometric studies on scientific activity provide essential information to promote gender equality. An annual increase over 1% in the number of female authors in the journal has been observed, which if it continues will lead to a parity in coming years.

[Institutionalization of the sciences, gender system, and scientific production in Brazi (1939-1969)]

Thanks to policies put in place in the 1930s, women's experiences in higher education increased their professional participation in the academic and scientific worlds. Largely neglected in Brazilian historiography of the sciences, analysis of this phenomenon introduces a new perspective on the meaning of institutionalization and professionalization of scientific activities, a process in which women have played an authentic role. We explore their presence by analyzing the scientific production published in four journals between 1939 and 1969. Gender differences are detected according to the standard of the publication.

Varieties of publication patterns in neuroscience at the cognitive turn

The quantification of publication activity and impact has become a key element in the evaluation of scientific excellence. However, it is unclear to what extent this grasps the diversity of research communication that accompanies the transition of scientific fields. This contribution investigates number, categorization, and impact of publications (i.e., publication patterns) of six scientists active at the cognitive turn, which promoted the information processing perspective on neuronal processes in different communities: Horace Barlow, Theodore Bullock, Ralph Gerard, Donald MacKay, Warren McCulloch, and Werner Reichardt. The large variety of publication patterns revealed indicates the limits of standardized evaluation procedures based on publication activity.

Written accounts of an Amazonian landscape over the last 450 years

Books, articles, government documents, and other written accounts of tropical biology and conservation reach a tiny fraction of their potential audience. Some texts are inaccessible because of the language in which they are written. Others are only available to subscribers of developed-world journals, or distributed narrowly within tropical countries. To examine this dysfunction in the tropical literature--and what it means for conservation--we tried to compile everything ever written on the biology and conservation of the department of Madre de Dios, Peru, in southwestern Amazonia. Our search of libraries, databases, and existing bibliographies uncovered 2,202 texts totaling roughly 80,000 pages. Texts date from 1553 to 2004, but 93% were written after 1970. Since that year the publication rate has increased steadily from fewer than 10 texts/year to nearly 3 texts/week in 2004. Roughly half of the Madre de Dios bibliography is in Spanish-language texts written by Peruvian authors and mostly inaccessible outside Peru. Most of the remaining material is English-language texts written by foreign authors and largely inaccessible in Peru. Foreign authors tended to write about ecological studies with limited relevance to on-the-ground conservation challenges, whereas Peruvian authors were more likely to make specific management recommendations. The establishment of a Web-based digital library for Neotropical nature would help make the tropical literature a more efficient resource for science and conservation. Additional recommendations include investing in syntheses, translations, popular summaries, and peer-reviewed journals in tropical countries, providing incentives for management-relevant research in tropical protected areas, and reinforcing training of scientific reading and writing in tropical universities.

[Ten year jubilee of the journal "Advances in Gerontology"]

The article presents the report of the editorial board of the journal "Advances in Gerontology" devoted to 10th anniversary since the first publication. Analysis of character of the articles printed during last 5 years has been given, including their distribution by geography, departmental membership, and science themes. Geographic widening of the publications, increasing of number of institutions delivering the articles and of number of articles as well as number of the authors has been shown. These showings are the evidence of the fact that gerontology attracts more and more attention of the specialists.

Ernst Wynder: citation analysis

Ernst Wynder published nearly 800 papers during his lifetime. I used the ISI Web of Science to analyze his publications and the subsequent literature citing his work. More than half of his papers were published in just ten journals, including Cancer, Preventive Medicine (which he founded and edited), JNCI, and Cancer Research. The 87 papers in Cancer covered all of the major cancer sites including breast, colon, lung, and prostate, and many others. Twenty-five papers and one book were cited in over 200 publications. His publications included 441 co-authors from a broad range of scientific disciplines.

Bibliometric analysis of Human Factors (1970-2000): a quantitative description of scientific impact

Bibliometric analyses use the citation history of scientific articles as data to measure scientific impact. This paper describes a bibliometric analysis of the 1682 papers and 2413 authors published in Human Factors from 1970 to 2000. The results show that Human Factors has substantial relative scientific influence, as measured by impact, immediacy, and half-life, exceeding the influence of comparable journals. Like other scientific disciplines, human factors research is a highly stratified activity. Most authors have published only one paper, and many papers are cited infrequently, if ever. A small number of authors account for a disproportionately large number of the papers published and citations received. However, the degree of stratification is not as extreme as in many other disciplines, possibly reflecting the diversity of the human factors discipline. A consistent trend of more authors per paper parallels a similar trend in other fields and may reflect the increasingly interdisciplinary nature of human factors research and a trend toward addressing human-technology interaction in more complex systems. Ten of the most influential papers from each of the last 3 decades illustrate trends in human factors research. Actual or potential applications of this research include considerations for the publication and distribution policy of Human Factors.
