Bibliometric insights into microalgae cultivation in wastewater: Trends and future prospects for biolipid production and environmental sustainability.

Cultivation of microalgae in wastewater stream has been extensively reported, especially for simultaneous production of biolipid and wastewater treatment process. This study aimed to derive the research trend and focus on biolipid production from microalgae cultivated in wastewater by using bibliometric approach. The search strategy used in Scopus database resulted in 1339 research articles from 1990 to November 2023. Majority of publications (46%) were affiliated to China and India, showing their predominance in this field. Keywords related to the center of attention included biodiesel, biofuel, biomass and nutrient removal. Meanwhile, keyword with recent publication year, indicating the emerging research trends, revolved around the cultivation techniques and application of the system. Co-culture involving more than one microalgae species, bacteria and yeast showed promising results, while addition of nanoparticles was also found to be beneficial. Increasing exploration on the application of microalgae for treatment of saline wastewater was also reported and the carbon fixation mechanism by microalgae has been widely investigated to promote less environmental impact. Future research on these topics were suggested based on the findings of the bibliometric analyses.

Sustainable management of food waste; pre-treatment strategies, techno-economic assessment, bibliometric analysis, and potential utilizations: A systematic review.

Food waste (FW) contains many nutritional components such as proteins, lipids, fats, polysaccharides, carbohydrates, and metal ions, which can be reused in some processes to produce value-added products. Furthermore, FW can be converted into biogas, biohydrogen, and biodiesel, and this type of green energy can be used as an alternative to nonrenewable fuel and reduce reliance on fossil fuel sources. It has been demonstrated in many reports that at the laboratory scale production of biochemicals using FW is as good as pure carbon sources. The goal of this paper is to review approaches used globally to promote turning FW into useable products and green energy. In this context, the present review article highlights deeply in a transdisciplinary manner the sources, types, impacts, characteristics, pre-treatment strategies, and potential management of FW into value-added products. We find that FW could be upcycled into different valuable products such as eco-friendly green fuels, organic acids, bioplastics, enzymes, fertilizers, char, and single-cell protein, after the suitable pre-treatment method. The results confirmed the technical feasibility of all the reviewed transformation processes of FW. Furthermore, life cycle and techno-economic assessment studies regarding the socio-economic, environmental, and engineering aspects of FW management are discussed. The reviewed articles showed that energy recovery from FW in various forms is economically feasible.

Textile waste water treatment: analysis of mapping knowledge domains.

Textile waste water contains dyes and chemicals that produce harmful vapors and exhaust gases, which is hazardous to the environment and public health. Therefore, it must be carefully treated before discharged. To understand the research evolution in the research area of textile waste water treatment, based on bibliometrics, an in-depth analysis of the publications and hotspots in this area was presented in this paper. For the analysis, totally 6774 papers related to the research area that are published between the year 1964 and 2023 were collected from the Web of Science Core Collection. Using CiteSpace and VOSviewer as bibliometric analysis tools, the collaboration of countries, regions, and organizations was investigated. Besides, an analysis for citation and co-citation of journals, authors, references, and co-occurrence of keywords was performed. The evolution of research hotspots in the three major research directions related to degradation, oxidation, and adsorption is also analyzed in this paper. The analysis results show that researches related to oxidation and adsorption are active in recent years, while nanocomposite adsorbents and graphene oxide are the current research hotspots.

A Bibliometric Analysis of the Journal of Religion and Health: Sixty Years of Publication (1961-2021).

In 1961, the Journal of Religion and Health (JORH) commenced publishing articles that examined modern religious and spiritual philosophy in relation to psychology and health. The year 2021 marked the 60th anniversary of the founding of JORH. This research paper retrospectively analyses the journal's content. It provides insight into JORH's publication trends, citation records, prominent themes, authors' collaboration and its aggregate contribution to the field of religion and health. Over time, the number of publications, citations and downloads of JORH articles have substantially increased, as has the journals prominence and diverse contributions to the study of religion, spirituality and health.

Discovering future research trends of aerobic granular sludge using bibliometric approach.

The advantageous characteristics of aerobic granular sludge (AGS) have led to their increasing popularities among academics and industrial players. However, there has been no bibliometric report on current and future research trends of AGS. This study utilized the available reports of AGS in the Scopus database for comprehensive bibliometric analyses using VOSviewer software. A total of 1203 research articles from 1997 to 2020 were analyzed. The dominance of the Netherlands and China were revealed by the high number of publications and citations. Nevertheless, the Netherlands exhibited higher average citation per article at 76.4. A recent process of AGS involving biochar and algal addition were also identified. Meanwhile, the application of AGS for antibiotic containing wastewater as well as possibility of resource recovery were recently reported and was expected to expand in the future. It was suggested that application of AGS would develop further along with the development of sustainable wastewater treatment process.

The scientific productions in Iranian biomedical ethics: A combined study of bibliometrics and social network analysis.

This study aims at increasing our understanding of the research activities of Iranian researchers and institutions in the field of biomedical ethics from 1995 to 2015. A combination of bibliometrics and social network analysis was used to examine the bibliographic data of 580 documents published on Iranian biomedical ethics in Web of Science and Scopus databases to investigate the publication trend, scientific impact, subject keywords network, and social network analysis indicators for international and cross-institutional co-authorship networks. The results showed that the publication of documents has had a consistent and increasing growth and that the citation trend has grown along with it. The analysis of thematic clusters by keyword co-occurrence network shows that Iranian biomedical ethics research has dealt with various topics and that has introduced different research directions. Researchers from 28 countries were identified in the international collaboration network. The main partners of Iranian researchers were from the US (17.8%) and the UK (9.2%). However, there is a tendency to develop and complete cooperation with researchers from different countries. The cross-institutional collaboration network comprises of 63 institutes, of which Tehran University of Medical Sciences (38%), Shahid Beheshti University of Medical Sciences (11%) and Shiraz University of Medical Sciences (7%) have the largest share in publishing documents. The superiority of the first two universities based on centralization indicators in the cross-institutional collaboration network has caused the exchange of cross-network knowledge between and via these players. The network density indicator shows that almost half of the co-authorship links within the international collaboration network and 8% of the co-authorship links within the cross-institutional collaboration network have been implemented and that these networks are not very coherent.

A Bibliometric Study of the Pediatric Inguinal Hernia Publication Landscape from the Web of Science Database.

Background: The number of times a research work gets cited by another article is one of the article-level metrics for assessing the quality of a research publication. Citation analysis by bibliometric review has been performed in several disciplines. The current study was aimed to systematically review the literature available on pediatric inguinal hernia since 1960 in terms of the 25 most cited articles in this field and analyze the bibliometric variables author and organizational collaborative patterns. Methods: Thomson Reuters Web of Science citation indexing database and research platform were used to retrieve the most cited articles in pediatric inguinal hernia (PIH) using appropriate search strings. The characteristics (name of authors, the total number of authors, the title of publication, journal of publication, year of publication, etc.) of the 25 top-cited articles were recorded. Specific bibliographical parameters were derived and analyzed. Visualization maps were generated using VOSviewer software. Results: The analysis revealed that the Journal of Pediatric Surgery was leading the choice of journal for publication. While most of the publications originated from the United States of America, Schier was the most influential author. Five of the eight top-productive authors are also the most connected. Conclusion: Articles on laparoscopic repair in PIH have been heavily cited. Following the United States of America, Turkey stands out as the topmost productive country in PIH. The publications on PIH show that "collaboration" is the bridging force between productivity and influence on the academic community.

Collaboration on evidence synthesis in Africa: a network study of growing research capacity.

BACKGROUND: Evidence-based practice in medicine and social policy relies heavily on evidence synthesis. To translate evidence into practical guidelines for low- and middle-income countries, local expertise is essential. The objectives of this study are to assess the change in capacity for conducting evidence synthesis in Africa and to identify key African institutions for regional capacity-building. We take on a network perspective, considering that the position of an institution in the African evidence ecosystem is one constituent of its research capacity. METHODS: We systematically identified 3548 evidence synthesis publications between 2008 and 2019 with at least one author in Africa from the Web of Science Core Collection. These articles involved 3769 institutions. Longitudinal institution-level collaboration network data were constructed based on co-authorship information. We used social network analysis to examine the institutions' connectivity and tendency for intra- and interregional collaboration. We also identified the degree- and betweenness-central African institutions and explored the structure and composition of their local network neighbourhoods. RESULTS: The number of African institutions involved in evidence synthesis has increased substantially over the last decade, from 31 in 2008 to 521 in 2019, and so has the number of evidence synthesis publications with authors in Africa. African institutions in the evidence ecosystem have also become more connected during this period. Although the amount of intercontinental collaboration continues to exceed that of regional collaboration, the tendency for African institutions to collaborate with partners in Africa is increasing. We identified seven institutions-in South Africa, Egypt and Uganda-as central to the collaboration networks between 2008 and 2019, all of whom showed a tendency to collaborate across sectors. CONCLUSION: The development of more regionally based network-building initiatives would help to foster communities of practice and inter-institutional collaboration, strengthening regional research capacity. Moreover, the analysis in this study adds depth beyond a simple bibliometric analysis and illustrates that network analysis could provide a useful tool to evaluate the effectiveness of capacity-building strategies and programmes in the future.

International Scientific Collaboration on Pituitary Research: A Social Network Analysis.

Background: Social network analysis (SNA) evaluates the connections and behavior of individuals in social groups. The scientific collaboration network is a kind of SNAs. A social network could be defined as a collection of nodes (social existence) and links (connections) associated with the nodes. The aim of this study was to evaluate the scientific outputs and collaboration networks of the countries and authors using indicators of SNA in the field of pituitary disorders between 2000 and 2020. Methods: This is a practical study performed by applying a scientometric approach and SNA. We retrieved 31257 papers in the field of pituitary disorders between 2000 and 2020. Data were analyzed using scientific software, namely, VOSviewer, UciNet, and Netdarw. Results: Based on degree centrality, Colao and Pivonello in the world, Shimon and Kadioghlu in the Middle-East (ME), and Khamseh, Ghorbani in Iran achieved the top ranking. Based on the betweenness centrality, Pivonello, Colao, and Chanson in the world, Laws, and Kadioghlu in the Middle-East, and Larijani, Mohseni, and Khamseh in Iran were known as the top authors. According to closeness centrality, Pivonello, Colao, and Chanson in the world, Kadioghlu and Kelestimur in the Middle-East, and Mohseni, Khamseh, and Larijani in Iran were the top authors. The map of the authors' collaboration in the field of pituitary disorders consists of 92 nodes. A total number of 77313 authors had global collaboration. The global collaboration network was comprised of 129 nodes (country) and 2694 links (country's collaboration). The Middle-East collaboration network revealed 69 nodes and 1708 links. The collaboration network of the Middle-East countries consists of 13 nodes and 50 links. Conclusion: Authors with a higher degree, betweenness and closeness centrality have greater efficiency (the number of articles) and effectiveness (the number of received citations). Moreover, the authors and countries that published more scientific products received more citations. In addition, in the Middle-East countries, the interdisciplinary scientific collaboration between the researchers in the fields of endocrinology, neurosurgery, pathology, and radiology has a significant impact on improving scientific outputs.

Contributorships Are Not 'Weighable' to be Equal.

A new trend to assign some authors as 'first co-authors' is noticeable in scientific publications as a statement highlighting that two or more authors 'contributed equally' to a reported work. However, the requirements of scientific rigor, honesty, and accuracy in academic standards make such statements invalid and, thus, should be avoided. A potential solution is to specify the role of each co-author, from study conception to communication of results, and let readers judge the importance of each contribution by themselves. Alternatively, authors should demonstrate how they contributed 'equally' when they are defined as 'equal contributors'.

Equal Co-authorship Practices: Review and Recommendations.

There has been an increase in the number of journal articles that are co-authored by researchers who claim to have made equal contributions. This growth has sparked discussions in the literature, especially within medical journals. To extend the debate beyond medical disciplines and support journal editors in forming an opinion, the current review collates and explores published viewpoints about so-called Equal Co-authorship (EC) practices. The Web of Science core database was used to identify publications that mention and discuss EC. Within the limited number of publications that were found on the Web of Science database, the most-cited item was used to trace other papers that discuss EC. In total, 39 papers (including articles and editorials) met the inclusion criteria. This review identifies four main themes within the sample including the growth of EC, challenges of attributing EC, guidelines and policies about EC and gender issues in the attribution of EC. Based on the survey and analysis of publications that discuss EC, this review provides recommendations regarding journal policy statements, and EC indicators. Those recommendations include: (1) journal policies should address EC; and (2) use should be made of available functionalities (CRediT, for example) to capture and indicate equal contributions.

Perils of Precipitate Publication: Fraudulent and Substandard COVID-19 Research.

The COVID-19 pandemic has created an environment highly conducive to substandard and fraudulent research. The incentives and temptations for the unethical are substantial. The articles published during 2020 in The Lancet and the New England Journal of Medicine that were based on spurious datasets, allegedly hosted by a cloud-based health care analytics platform, are deeply confronting for research integrity. They illustrate the perils of precipitate publication, inadequate peer-reviewing and co-authorship without proper assumption of responsibility. A period of crisis such as that in existence during the COVID-19 pandemic calls for high-quality research that is robustly evaluated. It is not a time for panic to propel premature publication or for relaxation in scholarly standards. Any other approach will replicate errors of the past and result in illusory research breakthroughs to global detriment.

Scientific and technological contributions of Latin America and Caribbean countries to the Zika virus outbreak.

BACKGROUND: The recent Zika virus (ZIKAV) epidemics disclosed a major public health threat and a scientific and technological (S&T) challenge. The lessons learned from the S&T response of Latin America and the Caribbean (LAC) countries are critical to inform further research and guide scientific investments. The present study aimed to assess how new S&T knowledge produced and disseminated regionally can contribute to address global health challenges. METHODS: Scientometric and social network analysis methods were used to assess the LAC scientific contribution and potential technological development on ZIKAV up to December 2017. ZIKAV-related publications were retrieved from the Web of Science, Scopus, and PubMed databases. Regionally published articles were obtained from SciELO (Scientific Electronic Library Online) and LILACS (Literature in the Health Sciences in Latin America and the Caribbean) databases. Patent registries were retrieved using Orbit Intelligence and Derwent Innovation. Records from each database were individually downloaded, integrated, standardized and analyzed. RESULTS: We retrieved 5421 ZIKAV-related publications, revealing a sharp increase from 2015 onwards. LAC countries accounted for 20% of all publications and Brazil was among the top three most central countries in the global network for ZIKAV research. A total of 274 patent families backed up by experimental evidence were retrieved. Only 5% were filed by LAC assignees, all of them based in Brazil. The largest contribution of LAC research was on the clinical manifestations of the ZIKAV infection, along with vector control, which was also the main focus of patents. CONCLUSIONS: Our analysis offered a comprehensive overview of ZIKAV's research and development and showed that (i) LAC countries had a key role in generating and disseminating scientific knowledge on ZIKAV; (ii) LAC countries have expressively contributed to research on ZIKAV clinical manifestations; (iii) the Brazilian scientific community was potentially very effective in knowledge sharing and diffusion in the ZIKAV research network; (iv) Brazil was the single LAC country filing patents, mostly represented by independent inventors and low-tech patents. The paper advocates the need for a continued interdisciplinary approach to improve LAC countries ability to prevent, prepare for and control future outbreaks.

South-south collaboration on HIV/AIDS prevention and treatment research: when birds of a feather rarely flock together.

BACKGROUND: South-south collaboration on health and development research is a critical mechanism for social and economic progress. It allows sharing and replicating experiences to find a "southern solution" to meet shared health challenges, such as access to adequate HIV/AIDS prevention and treatment. This study aimed to generate evidence on the dynamics of south-south collaboration in HIV/AIDS research, which could ultimately inform stakeholders on the progress and nature of collaboration towards increased research capacities in low- and middle-income countries (LMIC). METHODS: Bibliometric and social network analysis methods were used to assess the 10-year (2006-2015) scientific contribution of LMIC, through the analysis of scientific publications on HIV/AIDS prevention and/or treatment. Five dimensions oriented the study: knowledge production, co-authorship analysis, research themes mapping, research types classification and funding sources. RESULTS: Publications involving LMIC have substantially increased overtime, despite small expression of south-south collaboration. Research themes mapping revealed that publication focus varied according to collaborating countries' income categories, from diagnosis, opportunistic infections and laboratory-based research (LMIC single or LMIC-LMIC) to human behavior and healthcare, drug therapy and mother to child transmission (LMIC-HIC). The analysis of research types showed that south-south collaborations frequently targeted social sciences issues. Funding agencies acknowledged in south-south collaboration also showed diverse focus: LMIC-based funders tended to support basic biomedical research whereas international/HIC-based funders seem to cover predominantly social sciences-oriented research. CONCLUSIONS: Although the global environment has fostered an increasing participation of LMIC in collaborative learning models, south-south collaboration on HIV/AIDS prevention and/or treatment research seemed to be lower than expected, stressing the need for strategies to foster these partnerships. The evidence presented in this study can be used to strengthen a knowledge platform to inform future policy, planning and funding decisions, contributing to the development of enhanced collaboration and a priority research agenda for LMICs.

Health policy and systems research collaboration pathways: lessons from a network science analysis.

BACKGROUND: The 2004 Mexico Declaration, and subsequent World Health Assembly resolutions, proposed a concerted support for the global development of health policy and systems research (HPSR). This included coordination across partners and advocates for the field of HPSR to monitor the development of the field, while promoting decision-making power and implementing responsibilities in low- and middle-income countries (LMICs). METHODS: We used a network science approach to examine the structural properties of the HPSR co-authorship network across country economic groups in the PubMed citation database from 1990 to 2015. This analysis summarises the evolution of the publication, co-authorship and citation networks within HPSR. RESULTS: This method allows identification of several features otherwise not apparent. The co-authorship network has evolved steadily from 1990 to 2015 in terms of number of publications, but more importantly, in terms of co-authorship network connectedness. Our analysis suggests that, despite growth in the contribution from low-income countries to HPSR literature, co-authorship remains highly localised. Lower middle-income countries have made progress toward global connectivity through diversified collaboration with various institutions and regions. Global connectivity of the upper middle-income countries (UpperMICs) are almost on par with high-income countries (HICs), indicating the transition of this group of countries toward becoming major contributors to the field. CONCLUSIONS: Network analysis allows examination of the connectedness among the HSPR community. Initially (early 1990s), research groups operated almost exclusively independently and, despite the topic being specifically on health policy in LMICs, HICs provided lead authorship. Since the early 1990s, the network has evolved significantly. In the full set analysis (1990-2015), for the first time in HPSR history, more than half of the authors are connected and lead authorship from UpperMICs is on par with that of HICs. This demonstrates the shift in participation and influence toward regions which HPSR primarily serves. Understanding these interactions can highlight the current strengths and future opportunities for identifying new strategies to enhance collaboration and support capacity-building efforts for HPSR.

Trouble in Paradise: Problems in Academic Research Co-authoring.

Scholars and policy-makers have expressed concerns about the crediting of coauthors in research publications. Most such problems fall into one of two categories, excluding deserving contributors or including undeserving ones. But our research shows that there is no consensus on "deserving" or on what type of contribution suffices for co-authorship award. Our study uses qualitative data, including interviews with 60 US academic science or engineering researchers in 14 disciplines in a set of geographically distributed research-intensive universities. We also employ data from 161 website posts provided by 93 study participants, again US academic scientists. We examine a variety of factors related to perceived unwarranted exclusion from co-author credit and unwarranted inclusion, providing an empirically-informed conceptual model to explain co-author crediting outcomes. Determinants of outcomes include characteristics of disciplines and fields, institutional work culture, power dynamics and team-specific norms and decision processes.

[Equally or equitably? Author roles and co-author shares in scientific publication]. / Igazságosan vagy testvériesen? Szerzoi szerepek és társszerzoi részesedések a tudományos publikálásban.

In the last decades the share of co-authored and, particularly, multi-authored papers has increased immensely. The paper deals with the causes and consequences of this phenomenon, specifically with those connected with scientometric analyses. Possibilities for fractional count of publications and citations, as well as problems of interpreting h-index and self-citation in case of multi-authored papers are focused upon.

Writers Blocked: On the Wrongs of Research Co-authorship and Some Possible Strategies for Improvement.

The various problems associated with co-authorship of research articles have attracted much attention in recent years. We believe that this (hopefully) growing awareness is a very welcome development. However, we will argue that the particular and increasing importance of authorship and the harmful implications of current practices of research authorship for junior researchers have not been emphasised enough. We will use the case of our own research area (bioethics) to illustrate some of the pitfalls of current publishing practices-in particular, the impact on the evaluation of one's work in the area of employment or funding. Even where there are explicit guidelines, they are often disregarded. This disregard, which is often exemplified through the inflation of co-authorship in some research areas, may seem benign to some of us; but it is not. Attribution of co-authorship for reasons other than merit in relation to the publication misrepresents the work towards that publication, and generates unfair competition. We make a case for increasing awareness, for transparency and for more explicit guidelines and regulation of research co-authorship within and across research areas. We examine some of the most sensitive areas of concern and their implications for researchers, particularly junior ones, and we suggest several strategies for future action.
