Publication Trend on Insurance Efficiency Studies

This study aims to determine the map of the development of research on the theme of insurance efficiency which is published in journals equipped with digital object identifiers. The research was conducted in August 2023. The data analyzed were 336 research journals related to insurance efficiency published from 1992 to 2023. During this period, the most research on insurance efficiency occurred in 2022 with 40 publications. The data is then processed and analyzed using the VOSviewer application program to determine the bibliometric mapping for the development of insurance efficiency research. The results show that cost efficiency, economy, evidence, firm, insurance firm, insurance sector, market, risk, originality value, relationship and stage data envelopment are the most widely used topics. The research development map for this theme is divided into 5 clusters. Cluster 1 consists of 11 topics, cluster 2 consists of 9 topics, cluster 3 consists of 9 topics cluster 4 consists of 5 topics and cluster 5 consists of 5 topics.

The international platform of registered systematic review and meta-analysis protocols (INPLASY) at 3 years: an analysis of 4,658 registered protocols on inplasy.com, platform features, and website statistics.

INPLASY® is an international platform for registering systematic reviews and meta-analysis protocols that was launched in March 2020. INPLASY® provides an online database in which the protocols are maintained as permanent public records and can be accessed on its website (www.inplasy.com). We described the database features and registered information of all records published since the launch of the registry on March 31, 2023. Additionally, we analyzed the website statistics dataset to explore user experience and promote data transparency. Four thousand six hundred fifty-eight records were registered in INPLASY®, and more than 94% of the protocols were published within 24 h. Most of the submissions were from China, followed by Portugal, Taiwan, Malaysia, and Brazil. The INPLASY® website received 386,395 page views from 64,568 visitors during the first three years. The accesses were obtained from 170 countries. Most of the accesses were from China, followed by the US, the UK, and Portugal. The review status "completed and published" was observed in 898 protocols, and these studies were published in 372 different scientific peer-reviewed journals. The features of INPLASY® include the following: (i) INPLASY® identifier, a unique protocol number; (ii) the digital object identifier (DOI) number, the URL of the protocol linked to a specific DOI; (iii) ORCID update, INPLASY® automatically updates authors' ORCID page, including their protocol; and (iv) search tools, the protocols are freely accessible on www.inplasy.com. INPLASY® has several practical and useful features that should be considered when planning the registration of a systematic review protocol. Furthermore, the sharp increase in the number of protocols registered in INPLASY® in the first three years and the database statistics demonstrate that INPLASY® has become an important source of systematic review protocols. Therefore, authors should access INPLASY® before planning a future review study to avoid unintended duplication of efforts and to obtain timely registration.

Digital object identifier: What it is and why it matters?

Digital object identifiers (DOIs) have become essential tools in academic publishing for linking and identifying digital objects. This review examines the structure and assignment process of DOIs, shedding light on their critical importance in scholarly communication. DOIs consist of a unique alphanumeric string, including a prefix and a suffix, which serves as a persistent link to digital objects. By providing a standardized identifier, DOIs enhance the discoverability, accessibility, and referencing of various digital objects, including journal articles. The DOI also plays a crucial role in article promotion. With a DOI, authors, publishers, and researchers can effectively share and promote their articles, facilitating their discoverability in academic and research communities. However, challenges may arise with DOIs, such as non-functional links. This review provides troubleshooting tips for resolving such issues, including checking for typographical errors, validating the source, and seeking assistance from the DOI registration agency or the publisher.

Landolt Indicator Values in Modern Research: A Review

The conservation of biodiversity and ecosystem sustainability is essential for human well-being. An important tool for addressing this issue is ecological indicators. This overview document examines recent studies covering the period 2018–2022 that use the values of the Landolt indicator as one of the analysis methods. The total number of records examined was 8910. After excluding irrelevant, inconsistent and duplicate records, 91 records were selected. The selection criteria were the presence of the English abstract and a digital object identifier (DOI). We chose the VOSviewer software for data analysis and visualization. The analysis of research geography, types of plant communities under research, research topics, the network of co-authorship and relationship papers, as well as the publication activity and citation rate of the authors, is carried out. The results revealed that the geography of using Landolt indicator values is quite wide, while they are more often used in Switzerland, Italy and Russia. The most important and frequently cited studies were carried out in the context of large international projects, confirming the importance of scientific cooperation in the development of environmental indicators. The Landolt indicator values showed effectiveness in the study of forests, bogs, riparian vegetation, a coarse quarry waste dump, and in assessing the urban environment. At the same time, the vegetation dynamics and influence of various factors on plants were studied most often. It was revealed that Landolt indicator values can serve as an effective universal method that integrates many aspects of the environment and allows for a comprehensive multicriteria analysis of environmental factors, habitat stability, vegetation diversity and dynamics for different plant communities at different spatial scales over a wide geographical area. This is confirmed by the high citation rate of the papers. We recommend the Landolt indicator values for a wider use, including in the monitoring of ecosystems and individual species for their conservation and sustainable management. In order to achieve this goal, it is necessary to extend the network of relationships between the authors, which is not very well developed at the moment. The research results obtained are useful for the further successful development not only of the Landolt indicator values but also of environmental indicators in general.

Open access books through open data sources: assessing prevalence, providers, and preservation

PurposeScience policy and practice for open access (OA) books is a rapidly evolving area in the scholarly domain. However, there is much that remains unknown, including how many OA books there are and to what degree they are included in preservation coverage. The purpose of this study is to contribute towards filling this knowledge gap in order to advance both research and practice in the domain of OA books.Design/methodology/approachThis study utilized open bibliometric data sources to aggregate a harmonized dataset of metadata records for OA books (data sources: the Directory of Open Access Books, OpenAIRE, OpenAlex, Scielo Books, The Lens, and WorldCat). This dataset was then cross-matched based on unique identifiers and book titles to openly available content listings of trusted preservation services (data sources: Cariniana Network, CLOCKSS, Global LOCKSS Network, and Portico). The web domains of the OA books were determined by querying the web addresses or digital object identifiers provided in the metadata of the bibliometric database entries.FindingsIn total, 396,995 unique records were identified from the OA book bibliometric sources, of which 19% were found to be included in at least one of the preservation services. The results suggest reason for concern for the long tail of OA books distributed at thousands of different web domains as these include volatile cloud storage or sometimes no longer contained the files at all.Research limitations/implicationsData quality issues, varying definitions of OA across services and inconsistent implementation of unique identifiers were discovered as key challenges. The study includes recommendations for publishers, libraries, data providers and preservation services for improving monitoring and practices for OA book preservation.Originality/valueThis study provides methodological and empirical findings for advancing the practices of OA book publishing, preservation and research.

Making Research FAIR With a PID-centric Workflow

Persistent identifiers (PIDs) are unique, machine-readable codes assigned to research entities that allow them to be easily discoverable. PIDs, along with their accompanying metadata, are crucial enablers of the FAIR principles (Findable, Accessible, Interoperable, and Reusable). PIDs ensure that digital objects can be located, accessed, and reused by humans and machines alike, while metadata provides essential information about research objects, including their origin, content, and format. In the research ecosystem, each stakeholder has a role to play in integrating PIDs into their workflows. Publishers, for example, can assign DOIs (Digital Object Identifiers) to articles, books, and other publications, making them easily findable and citable. Repositories can assign PIDs to datasets, making them discoverable and accessible. Researchers can use PIDs to link their data to their publications, ensuring that their data is discoverable and can be reused in future research. Despite the importance of PIDs and metadata, it's not always clear to researchers how to take advantage of the existing infrastructure and make their outputs FAIR. Being aware of the available PIDs, such as DOIs, ORCIDs, and RORs, and how they can be used to identify, connect, and cite various types of outputs and resources can help researchers plan and execute sensible data management, sharing, and publishing decisions that are efficient and beneficial in the long term. In the Implementing FAIR Workflows Project, DataCite works with a team of researchers at the Max Planck Institute for Empirical Aesthetics to follow along a neuroscience PhD project from the beginning, to design and plan for a series of workflows that put the FAIR principles into practice, so that they become an inherent part of the research process, instead of an afterthought. The FAIR workflows researcher is undertaking in the project include data management planning, experiment preregistration, domain-specific metadata capturing and archiving, data and code sharing, preprinting, and open access publishing. We have also been tracking the time spent on various types of FAIR and Open activities, hoping to shed a light on the actual time commitment expected for a FAIRly conducted research project. We share our experience so far implementing these workflows with the Edinburgh Open Science community - the approach we used, the steps we’ve taken, and the outcomes and challenges that surfaced during the process. We are also preparing a guide for researchers to take on FAIR research workflows in their day-to-day work based on the lessons learned in the project, we look forward to taking the opportunity to hear from the community whether it resonates, and how can we format it in a way that’s most useful.

Introducing Article Numbering to Modern Pathology

Within the publishing industry, article numbering has emerged as an easy and efficient way to cite journal articles. Article numbering has already been successfully rolled out to more than 1,600 journals published by Elsevier and has been well received by the academic community. Based on that positive feedback, we are now pleased to introduce article numbering to Modern Pathology from Volume 36, Issue 1 (January 2023). What is article numbering? A unique article number is an abbreviated form of an article’s DOI - digital object identifier. Citing an article with an article number is very simple: the article number is used instead of the page range in the citation.2.Van der Geer J, Hanraads JAJ, Lupton RA. The art of writing a scientific article. Heliyon. 2018;19:100205. https://doi.org/10.1016/j.heliyon.2018.100205. While journal volumes and issue numbers will remain in place, article numbering will now play the key role in identifying specific articles. The introduction of article numbers brings several benefits for the journal and its readers and authors. Benefits of article numbering•More flexible reading: Article content can be optimized based on the device used to access it, supporting reading on-the-move, without needing to know how many traditional print pages the article takes up.•Increased options for grouping related content: In online collections and Special Issues, articles can now be placed in any order, helping readers to identify papers relevant to their research interests faster.•Faster publication: With article numbers, the version of record of the article is online and citable as soon as the proof corrections have been incorporated, ensuring readers have access to the latest research faster. What will change for me?•When citing articles, you will need to use the article number; see the example provided above. More examples of citing articles with article numbers are available in the Guide for Authors at the journal homepage on http://www.modernpathology.org/. Please note that the export citation functionality available on ScienceDirect for this journal already supports this new citation format.•Each article will have page numbers starting from page 1, but the issue itself will not have sequential page numbering. We are delighted that Modern Pathology’s readers and authors will now enjoy these benefits.

Inconsistent Citation of the Global Seismographic Network in Scientific Publications

Abstract The highly used Global Seismographic Network (GSN) is a pillar of the seismological research community and contributes to numerous groundbreaking publications. Despite its wide recognition, this survey found that the GSN is not consistently acknowledged in scientific literature and is underrepresented by roughly a factor of 3 in citation searches. Publication tracking is a key metric that factors into operational decisions and funding support for the network; thus, consistent and proper citation of the GSN is important. This study not only serves as a reminder for researchers using GSN observations to cite the network’s digital object identifiers (DOIs) but also promotes a community-wide conversation among researchers, journal editors, network operators, and other stakeholders regarding more standardized policies and review processes to ensure seismic networks are properly and consistently recognized for their contributions to research.

Introducing article numbering to the Journal of Allergy and Clinical Immunology: Global

Open access and international coauthorship: A longitudinal study of the United Arab Emirates research output

Abstract We investigate the interplay between open access (OA), coauthorship, and international research collaboration. Although previous research has dealt with these factors separately, there is a knowledge gap in how these interact within a single data set. The data includes all Scopus-indexed journal articles published over 11 years (2009–2019) where at least one of the authors has an affiliation to a United Arab Emirates institution (30,400 articles in total). To assess the OA status of articles, we utilized Unpaywall data for articles with a digital object identifier, and manual web searches for articles without. There was consistently strong growth in publication volume counts as well as shares of OA articles across the years. The analysis provides statistically significant results supporting a positive relationship between a higher number of coauthors (in particular international) and the OA status of articles. Further research is needed to investigate potentially explaining factors for the relationship between coauthorship and increased OA rate, such as implementation of national science policy initiatives, varying availability of funding for OA publishing in different countries, patterns in adoption of various OA types in different coauthorship constellations, and potentially unique discipline-specific patterns as they relate to coauthorship and OA rate.

Use of inactive Cochrane reviews in academia: A citation analysis

The Cochrane Database of Systematic Reviews is internationally recognized as one of the best sources of evidence within medical research. Nevertheless, a considerable amount of Cochrane reviews in the Cochrane Database of Systematic Reviews (CDSR) have not been updated for more than 5.5 years and are therefore considered inactive. This study’s aim was to evaluate if these are still used in academia. The study included 7,729 Cochrane reviews from the CDSR. Their Digital Object Identifiers (DOIs) were linked with citation data from the search engine The Lens. The citation pattern of 3,735 inactive reviews in the CDSR were analyzed and the results were adjusted for inflation in citation. A subgroup analysis of citing motives was performed for the most recent citations of the 20 most outdated reviews. In 2020, 41% of all citations of Cochrane reviews, were of reviews that had not been updated for more than 5.5. years. 5 years after last update, Cochrane reviews were on average cited 8.6 times per year. Twenty-five percent of Cochrane reviews were still cited 10 years after last update and were on average cited 4.3 times in the 10th year. None of the most recent citations of the 20 most outdated reviews indicated directly that the review was out of date. Cochrane reviews continued to be cited even though they were not being updated. This could pose a problem if they do not represent the most up-to-date evidence, as it may lead to the distribution of outdated evidence or misinformation.

Exploring the Boundaries of Reality: Investigating the Phenomenon of Artificial Intelligence Hallucination in Scientific Writing Through ChatGPT References.

Background Chatbots are computer programs that use artificial intelligence (AI) and natural language processing (NLP) to simulate conversations with humans. One such chatbot is ChatGPT, which uses the third-generation generative pre-trained transformer (GPT-3) developed by OpenAI. ChatGPT has been praised for its ability to generate text, but concerns have been raised about its accuracy and precision in generating data, as well as legal issues related to references. This study aims to investigate the frequency of AI hallucination in research proposals entirely drafted by ChatGPT. Methodology An analytical design was employed to investigate AI hallucination by ChatGPT. A total of 178 references listed by ChatGPT were verified for inclusion in the study. Statistical analysis was performed by five researchers who entered their data into a Google Form, and the final results were represented using pie charts and tables. Results Out of the 178 references analyzed, 69 references did not have a Digital Object Identifier (DOI), and 28 references neither turned up on Google search nor had an existing DOI. Three references were listed from books and not research articles. These observations suggest that ChatGPT's ability to generate reliable references for research topics may be limited by the availability of DOI and the accessibility of online articles. Conclusions The study highlights the potential limitations of ChatGPT's ability to generate reliable references for research proposals. AI hallucination is a problem that may negatively impact decision-making and may give rise to ethical and legal problems. Improving the training inputs by including diverse, accurate, and contextually relevant data sets along with frequent updates to the training models could potentially help address these issues. However, until these issues are addressed, researchers using ChatGPT should exercise caution in relying solely on the references generated by the AI chatbot.

Research Growth of Engineering Faculty Universitas Negeri Padang: A Bibliometric Study of Journal

This research aimed to conduct a comprehensive literature review of all papers from the beginning of time published by the Faculty of Engineering at Universitas Negeri Padang and indexed in the SINTA database using bibliometrics analysis. It started with a query to the DOI (Digital Object Identifier) database. The papers from this scholarly publication may be accessed here. A total of 1094 papers from 7 journals were collected. Each paper published by the Engineering Faculty at Universitas Negeri Padang receives an average of 0.42 citations. Given the insignificance of this average, it seems likely that the publication's contribution has yet to be fully recognized and has only had a little effect on the global state of knowledge. According to the findings, Universitas Negeri Andalas researchers collaborate the most with their peers around the country. Contrast this with the declining frequency with which multinational teams work together. With 38 articles published and ten citations obtained, Ahmaddul Hadi of the Informatics Department stood out as the most productive author. Research conducted by this faculty has been widely disseminated due to its publication in the reputable academic journal Inovasi Vokasi Dan Teknologi (INVOTEK).

How to Handle a Case of Redundant Publications in Four Elsevier Journals?

Current ethical guidelines, as defined by the Committee on Publication Ethics (COPE), note that redundant publications or duplicate copies should be retracted because they partake no new information, and may be perceived as unfair. Elsevier and its journals are COPE members. In 2000, four Elsevier journals (Anaerobe, Journal of Theoretical Biology, Journal of Autoimmunity, Food Microbiology) published an identically worded notice related to the digital object identifier (DOI), i.e., it was published in quadruplicate (four copies). Despite an alert to all four journals about this quadruplicate, none were retracted. If academics would like to cite this announcement, which of the four copies should they use? This case study raises an important deontological argument regarding the laissez-faire attitude of these journals, which charge a fee (US$27.95-31.50) to access this document’s four PDFs. Yet, other cases of duplications/redundant publication in Elsevier journals are frequently retracted. In the case of these four DOI-related papers, what does ignoring the three redundant copies suggest?

The continued problem of URL decay: an updated analysis of health care management journal citations.

This study updates a 2009 study which examined uniform resource locator (URL) decay in health care management journals and seeks to determine whether continued URL availability relates to publication date, resource type, or top-level domain. The authors also provide an analysis of differences in findings between the two study periods. The authors collected the URLs of web-based cited references in articles published in five health care management source journals from 2016 to 2018. The URLs were checked to see if they were still active and then analyzed to determine if continued availability was related to publication date, resource type, or top-level domain. Chi-square analysis was conducted to determine associations between resource type and URL availability, and top-level domain and URL availability. A Pearson's correlation was conducted to determine the relationship between publication date and URL availability. There were statistically significant differences in URL availability across publication date, resource type, and top-level domain. Domains with the highest percentage of unavailable URLs were .com and .net, and the lowest were .edu and .gov. As expected, the older the citation, the more likely it was unavailable. The overall percentage of unavailable URLs decreased from 49.3% to 36.1% between studies. URL decay in health care management journals has decreased in the last 13 years. Still, URL decay does continue to be a problem. Authors, publishers, and librarians should continue to promote the use of digital object identifiers, web archiving, and perhaps study and replicate efforts used by health services policy research journals to increase continued URL availability rates.

Measuring the Concept of PID Literacy: User Perceptions and Understanding of PIDs in Support of Open Scholarly Infrastructure

Abstract The increasing centrality of persistent identifiers (PIDs) to scholarly ecosystems and the contribution they can make to the burgeoning “PID graph” has the potential to transform scholarship. Despite their importance as originators of PID data, little is known about researchers’ awareness and understanding of PIDs, or their efficacy in using them. In this article, we report on the results of an online interactive test designed to elicit exploratory data about researcher awareness and understanding of PIDs. This instrument was designed to explore recognition of PIDs (e.g. Digital Object Identifiers [DOIs], Open Researcher and Contributor IDs [ORCIDs], etc.) and the extent to which researchers correctly apply PIDs within digital scholarly ecosystems, as well as measure researchers’ perceptions of PIDs. Our results reveal irregular patterns of PID understanding and certainty across all participants, though statistically significant disciplinary and academic job role differences were observed in some instances. Uncertainty and confusion were found to exist in relation to dominant schemes such as ORCID and DOIs, even when contextualized within real-world examples. We also show researchers’ perceptions of PIDs to be generally positive but that disciplinary differences can be noted, as well as higher levels of aversion to PIDs in specific use cases and negative perceptions where PIDs are measured on an “activity” semantic dimension. This work therefore contributes to our understanding of scholars’ “PID literacy” and should inform those designing PID-centric scholarly infrastructures that a significant need for training and outreach to active researchers remains necessary.

Open data-set identifier for open innovation and knowledge management

PurposeThis paper aims to highlight the importance of open data and the role that knowledge management and open innovation can play in its identification and use. Open data has great potential to create social and economic value, but its main problem is that it is often not easily reusable. The aim of this paper is to propose a unique identifier for open data-sets that would facilitate search and access to them and help to reduce heterogeneity in the publication of data in open data portals.Design/methodology/approachConsidering a model of the impact process of open data reuse and based on the digital object identifier system, this paper develops a proposal of a unique identifier for open data-sets called Open Data-set Identifier (OpenDatId).FindingsThis paper presents some examples of the application and advantages of OpenDatId. For example, users can easily consult the available content catalogues, search the data in an automated way and examine the content for reuse. It is also possible to find out where this data comes from, solving the problems caused by the increasingly frequent federation of data in open data portals and enabling the creation of additional services based on open data.Originality/valueFrom an integrated perspective of knowledge management and open innovation, this paper presents a new unique identifier for open data-sets (OpenDatId) and a new concept for data-set, the FAIR Open Data-sets.

Crossref as a bibliographic discovery tool in the arts and humanities

Abstract Crossref is an official digital object identifier registration agency launched in 2000 as a joint effort between publishers to allow persistent cross-publisher citation linking in online academic journals. Our study explores the coverage of Crossref for tracking literature in the arts and humanities, which usually has a national or regional focus and targets domestic audiences. An analysis of the coverage of ERIH PLUS journals shows that Crossref indexes more sources than Scopus and includes additional journals from Eastern and Southern Europe and the Global South. Crossref limitations arise when analyzing the amount of metadata deposited by publishers. Just two-thirds of the journals deposit abstracts and ORCIDs and around a third deposit affiliations. The level of metadata completion for individual articles is lower, with major differences depending on the language of the document. Just half of the journals actually deposit references. As a result, Scopus retrieves more citations than Crossref, except for publications in German and French. Crossref represents a promising bibliographic discovery tool in the arts and humanities but is in need of improvement regarding the level of metadata completion.
