Snakebite Envenoming - A Combined Density Equalizing Mapping and Scientometric Analysis of the Publication History

Toxic Habits: An Analysis of General Trends and Biases in Snake Venom Research

Biases in snake venom research have been partially identified but seldomly quantified. Using the Google Scholar web search engine, we collected a total of 267 articles published between 1964 and 2021, and reviewed them to assess the main trends in this field of study. We developed a 4-category classification of the harmful potential of each of the 298 snake species retrieved from the analysed publications, and tested whether taxonomy, realm of origin, and/or assigned hazard category could affect how often each of them appeared in the articles considered. Overall, viperids were significantly more represented than any other snake taxon retrieved. The Neotropics were the most represented biogeographic realm for number of studied species, whereas information about the country of origin of the analysed specimens was often incomplete. The vast majority of the publications focused on snake venom characterisation, whereas more ecology-related topics were rarely considered. Hazard category and biogeographic realm of origin of each species had a significant effect on the number of articles dedicated to it, suggesting that a snake's harmful potential and place of origin influence its popularity in venom studies. Our analysis showed an overall positive trend in the number of snake venom studies published yearly, but also underlined severe neglect of snake families of supposedly minor medical relevance (e.g., Atractaspididae), underrepresentation of some of the areas most impacted by snakebite (i.e., Indomalayan and Afrotropic realms), and limited interest in the ecological and functional context of snake venom.

Needlestick injuries: a density-equalizing mapping and socioeconomic analysis of the global research

Background

Needlestick injuries have caused a deleterious effect on the physical and mental health of millions of health-care workers over the past decades, being responsible for occupational infections with viruses such as HIV or hepatis C. Despite this heavy burden of disease, no concise studies have been published on the global research landscape so far.

Methods

We used the New Quality and Quantity Indices in Science platform to analyze global NSI research (n = 2987 articles) over the past 115 years using the Web of Science and parameters such as global versus country-specific research activities, semi-qualitative issues, and socioeconomic figures.

Results

Density-equalizing mapping showed that although a total of n = 106 countries participated in NSI research, large parts of Africa and South America were almost invisible regarding global participation in NSI research. Average citation rate (cr) analysis indicated a high rate for Switzerland (cr = 25.1), Italy (cr = 23.5), and Japan (cr = 19.2). Socioeconomic analysis revealed that the UK had the highest quotient Q_GDP of 0.13 NSI-specific publications per bill. US-$ gross domestic product (GDP), followed by South Africa (Q_GDP = 0.12). Temporal analysis of HIV versus hepatitis research indicated that NSI-HIV research culminated in the early 1990s, whereas NSI-hepatitis research increased over the observed period from the 1980s until the last decade.

Conclusion

Albeit NSI research activity is generally increasing, the growth is asymmetrical from a global viewpoint. International strategies should be followed that put a focus on NSI in non-industrialized areas of the world.

New quality and quantity indices in science (NewQIS): results of the first decade-project progress review

Strategies employing information science and scientometric approaches were introduced to science policy and management over the past decades. As a rapidly evolving field, new bibliometric parameters are proposed and discussed continuously and the fields also benefits from the introduction of novel visualization techniques. The present article summarizes the experiences with a platform that combines geographical mapping with scientometrics. It was established between 2005 and 2008 at the Charité in Berlin and termed “New Quality and Quantity Indices in Science” (NewQIS), consisting of the integration of common scientometric parameters such as the h-index and novel visualization techniques including density equalizing mapping. NewQIS was used to assess socio-economic important fields of medicine and sciences. Within NewQIS studies, research activities, citation patterns and their relation to socio-economic figures were analyzed with regard to time periods, countries, continents or even single cities. Within the decade after its establishment, more than 80 NewQIS articles were peer-reviewed and published. Being a non-funded low budget project, it was used by many medical students to conduct their MD thesis. The narrow technical frame led to the chance of a comparison of research output between different fields of science. This article summarizes NewQIS 1.0 activities, discusses its limits and gives a look into the future of NewQIS 2.0 with a target of 200 evaluated entities of the biomedical field of sciences.

Social sciences research in the Central European city of Wrocław: A density-equalizing mapping analysis

Background

The city of Wrocław in Poland represents one of Central Europeans oldest capitals of science with numerous Nobel laureates. Due to a long history of political suppressions with Nazi Germany and Communism from 1933 until 1989, its scientific community was suppressed for more than half a century.

Methods

The present study assessed scientific activities in the field of social and neighbouring sciences using density equalizing mapping. On the basis of the NewQIS (New Quality and Quantity Indices in Science) platform and the Social Sciences Citation Index (SSCI) of the Web of Science database, a total of 1787 articles originating from Wrocław were identified between 1966 and 2017.

Results

In total, 549 research collaborations of Wrocław with 96 different countries were present (30.7%). Among the 107 research areas the highest activity was found for the field of Business and Economics with n = 272 articles (average citation rate (AVR) of 12.54), followed by Psychology (n = 252 articles, AVR = 9.06), Psychiatry (n = 205 articles, AVR = 4.74) and Public, Environmental and Occupational Health (n = 145 articles, AVR = 7.96). The highest AVR was found for Operations Research (25.36 with n = 87 articles). Density equalizing mapping procedures revealed a global pattern of social sciences research collaborations with scientists from Germany, the UK and the US as the primary cooperating partner of Wrocław. The different countries had major differences in the area of research collaborations.

Conclusions

This is the first study that depicts the global network of Wrocław scientific activities in the field of social sciences. The exorbitant increase in research activity from 2006 onwards can lead to the assumption that Wrocław social sciences encounter a fruitful future.

Biomedical Research in Wrocław: A Combined Density-Equalizing Mapping and Scientometric Analysis

The aim of this study was to assess the evolution of biomedical scientific activities of Wrocław scientists in the post-war time when this field of academics was rebuilt by the works of Ludwik Hirszfeld and colleagues. Using the NewQIS platform and the Web of Science database, novel procedures such as density-equalizing mapping were combined to bibliometric tools to visualize scientific progression. In total, 10,366 biomedical research articles originating from Wrocław were identified. Since 1972, there is a steady increase in research activity with the year 2015 holding the largest number of published items (895). A total of 2934 published research cooperations with 104 different countries is present. This is a percentage of 28.3% of all publications. In total, 101 research areas are present in Wrocław biomedical research with the highest number of articles being published in the area of biochemistry/molecular biology (2140). Research in this field was cited 27,360 times. The field of immunology has 1186 articles with 9247 citations. Density-equalizing mapping and network techniques revealed a distinct global pattern of research collaborations with German, US and UK affiliations as the primary cooperating partners of Wrocław. In summary, the present study supplies the first density-equalizing mapping approach that visualizes research activity in Wrocław over the past decades.
