Reviewing excellence

Creativity and Innovation Management has grown substantially over the last couple of years, both quantitatively and qualitatively. From 2016 to 2021, the number of submissions has grown from 287 to 395. Most of the growth was realized in Asia: The number of submissions from that continent increased from 72 in 2016 to 193 in 2021. The rest of the world remained (close to) stable: 215 in 2016 and 203 in 2021. Equally important, the Thomson ISI Impact Factor increased from 1.423 in 2015 to 3.051 in 2021 and further to 3.644 in 2022. This is not where our ambitions end, though. We want to be the ever‐better outlet for authors researching, and practitioners working in, the fields we cover. Editing a journal with the ambition to continuously increase its quality while dealing with a substantial growth requires teamwork—teamwork among the editors and the editorial office, teamwork between the editors and their reviewers and, as surprising as this may sound, teamwork between the authors and their reviewers in a top‐quality reviewing process. The purpose of this piece is to present and discuss some reviewing standards. In particular, we aim to share with our reviewers what we think is an excellent reviewing process. Furthermore, we formulate our ideas about what it is that makes a review an excellent one. The title of this piece is deliberately ambiguous. It denotes that Creativity and Innovation Management strives for reviewing excellence—as in an excellent reviewing process. It also denotes that we reach for the stars and hope to one day receive and, hence, review only excellent submissions.

Impactos de eventos extremos de precipitação na qualidade da água: uma análise cienciométrica em escala global

Abstract: Aim This study aims to evaluate temporal patterns of extreme events related to precipitation on a global scale, identifying their main impacts and if there are climatic zones more susceptible to these phenomena using a scientometric approach. Methods A systematic review was conducted on scientific papers published between 1991 and July 2020, obtained from the Scopus and Thomson ISI Web of Science databases. Keywords related to precipitation extreme events and their effects on planktonic communities and freshwater ecosystems' water quality were used in the search. Results The analysis revealed a significant increase in publications, particularly from 2014 onwards, following the release of reports by the Intergovernmental Panel on Climate Change (IPCC) and the American Meteorological Society (AMS). These reports highlighted the increasing frequency of these climatic events and their potential for causing damage to humanity. In this review, we focused on extreme weather events related to precipitation such as droughts, rains, and floods. These events, due to their sudden volumetric changes, lead to immediate physical and chemical alterations in the water column. The main impacts of these extreme events on aquatic ecosystems include increased nutrient concentrations (mainly phosphorus and nitrogen), contamination by micropollutants, cyanobacteria blooms, and loss of biodiversity. Conclusions The scientometric analysis indicates that extreme weather events associated with precipitation have a detrimental effect on water quality and aquatic biodiversity, exacerbating the eutrophication process in freshwater systems.

The Top 100 Most Cited Articles on Platelet-Rich Plasma Use in Regenerative Medicine—A Bibliometric Analysis—From the ESSKA Orthobiologic Initiative

Over the past few decades, more and more articles about platelet-rich plasma (PRP) use in regenerative medicine have been published. The aim of this study was to determine which articles have been most influential in this field by identifying and analyzing the characteristics of the 100 most cited articles. Articles on the use of PRP in regenerative medicine were identified via the Thomson ISI Web of Science database. A majority of the articles originated from the USA (36%). The top journal in terms of number of articles was American Journal of Sports Medicine (12%). Musculoskeletal system and orthopedics (54%) were the most popular fields of applications. Preclinical studies were the most represented study type, from which only 8 from 46 (17.4%) provided a complete numerical description of the injected product. Analysis showed a time-dependent trend of increasing quality of the clinical studies (p = 0.004), although none of them provided a complete biological characterization of the injected PRP. This study demonstrated that the use of PRP in regenerative medicine is a growing and popular area of research, mainly focused on orthopedic applications. Studies on PRP-derived exosomes, biological characterization, and correlation with clinical results might be areas of future trends.

The Top 100 Most-Cited Articles on Arthroscopy: Most Popular Topic Is Rotator Cuff Rather Than Cartilage in the Last 5 Years

To highlight the characteristics of the 100 most-cited articles on arthroscopy and provide the variation trend of citation rate among the top 25 articles in the past 9 years. We further analyzed the topics of interest in the past or currently. The Thomson ISI Web of Science database was used to identify arthroscopy-related articles that were published from 1950 to March 31, 2020. The 100 most-cited articles were selected for further analysis. In addition, author key words of the articles that published in the recent 5 years were further analyzed. Mean of citations was 433.59 ± 400.73. The publication year ranged from 1980 to 2013. Most articles were focused on cartilage lesions and treatments (26%). A large proportion of articles were published in the 2000s (61%). Arthroscopy-the Journal of Arthroscopic and Related Surgery (23%) was the most popular journal. One half of the articles originated from the United States. The most prolific institution and first author were the Steadman Philippon Research Institute (5%) and Marc J. Philippon (4%), respectively. Most of the articles were Level IV evidence (33%). The citation rate increased by 131% from the previous top 25 articles published in 2011. A growth trend can be seen in the citation density over time. "Shoulder" (occurrences= 535) was the most used joint key word and "rotator cuff" (342) was the most used key word of research objective in the last 5 years, whereas "cartilage" only occurred 262 times. Based on bibliometric analysis of the 100 most-cited articles on arthroscopy combined with network analysis of the whole articles that published in the recent 5 years, the topic of most interest in the recent 5 years was rotator cuff rather than cartilage. The number of citations among the 25 most-cited articles is growing rapidly and has at least doubled in size on average in the past 9 years. Citation density among the 100 most-cited articles on arthroscopy has seen a growth trend. This article clarifies the characteristics of the 100 most-cited papers and provides guidance on the topics of interest in the past or currently as a roadmap for future research on arthroscopy.

Moreover, the keywords ACL, ACL reconstruction, ACL rupture, knee joint, knee injuries, and human showed the highest degree of centrality.Conclusion:By analyzing the characteristics of articles, this study demonstrated that ACLR is a growing and popular area of research, with the focus of research varying through timeline trends. Studies on anatomic reconstruction and biomechanics might be areas of future trends.

Upper Paraná River floodplain: synthesizing knowledge over time

Abstract: Aim Considering the great environmental and social impact that floodplains have, several studies have been performed in the upper Paraná River floodplain. In this study, we applied a scientometric analysis to understand the evolution of scientific knowledge generated in the Upper Paraná River floodplain, based on studies published in this area. Methods We searched the literature published from 1995 to 2018 using the indexed database - Thomson ISI Web of Science. The following information was obtained for each scientific article: a) year of publication; b) place of research; c) research institution; d) study approach; e) environments; f) subject matter; g) theoretical approach; h) taxonomic groups. Results We found 435 published articles from different study areas (such as: exact and earth sciences, environmental sciences, social and human sciences, health sciences) that used this floodplain as a study area. The linear regression model showed an increase in the number of articles throughout the years. Studies with ecological themes were most prominent, ensuring research with various theoretical approaches and different biological communities used as proxies. Conclusions With this study, we conclude that long-term research was fundamental in generating data to address ecological issues and describe the dynamics of this plain. Studies such as these must have more political and financial support to develop basic scientific studies that can subsidize data for conservation programs and government policies, in order to maintain ecosystem services such as fishing and the availability of quality water.

The global scientific literature on applications and trends in the use of functional morphological groups in phytoplankton studies

Abstract: Aim The application of deconstructive approaches in aquatic ecology has been increasing recently. Especially for phytoplankton, some functional classifications summarize similar traits of a group of species to understand organisms’ response to landscape variability. One of these approaches deals with phytoplankton functional classification based on morphology (MBFG - Morphologically Based Functional Groups). Focusing on this approach, we systematic mapping the scientific literature to reveal this functional framework´s applications for freshwater phytoplankton. Methods For this study, we selected from the Thomson ISI Web of Science database all articles published between 2010 and 2018 dealing with MBFG. We recorded 179 manuscripts citing the phytoplankton functional classification based on morphology and, among them, we excluded three due to lack of access to information. Results A clear temporal trend occurred with an increase in citations involving the morphological approach, with Brazil, Uruguay, and China as the countries with the highest number of studies. Of the total records, 60 manuscripts applied morphological classification in their studies, of which 23 manuscripts comprised comparative studies with other functional approaches. Most applications were for phytoplankton in lakes, with biomass being the most used metric for framing taxa in MBFG. The most often recorded groups are MBFG IV (medium-sized organisms without specialization), VII (large mucilaginous colonies), and III (large filamentous organisms with aerotopes). Conclusion This study showed an increasing trend in the number of studies that used the functional approach based on MBFG. We believe that deconstructive approaches, such as MBFG, help assess issues of interest in phytoplankton ecology.

The 50 Highest Cited Papers on Rotator Cuff Tear

The purpose of this study was to determine the 50 most cited articles on rotator cuff tear and their characteristics. Thomson ISI Web of Science was searched for the following search terms "rotator cuff" and "tear." The following characteristics were determined for each article: author(s), year of publication, source journal, geographic origin, article type (and subtype), and level of evidence for clinical articles. The number of citations ranged from 1558 to 253. The 50 most often cited articles were published in 7 journals. The majority of the articles (n= 46) were clinical, with the remaining representing some type of basic science research. Among clinical articles, the case series (n= 23) was the most common article subtype. Nine articles were methodologic in that they proposed a new classification/scoring system or technique. The most common level of evidence was Level IV (n= 31). This article provides clinicians, researchers, and trainees with a group of articles that should be taken into consideration as building blocks in the treatment of rotator cuff tears. Level IV, literature review.

Use of micronucleus assays for the prediction and detection of cervical cancer: a meta-analysis.

Cervical cancer (CC) is the fourth most common cancer in women; the survival rates depend strongly on its early detection. The Pap test is the most frequently used diagnostic tool, but due to its limited sensitivity/specificity, additional screening tests are needed. Therefore, we evaluated the use of micronucleus (MN) assays with cervical cells for the prediction and diagnosis of CC. MN reflects structural and numerical chromosomal aberrations. A search was performed in Pubmed, Scopus, Thomson ISI and Google Scholar. Subsequently, meta-analyses were performed for different grades of abnormal findings in smears and biopsies from patients which were diagnosed with CC. Results of 21 studies in which findings of MN experiments were compared with data from Pap tests show that higher MN frequencies were found in women with abnormal cells that are indicative for increased cancer risks. MN frequency ratios increased in the order inflammation (2.1) < ASC-US and ASC-H (3.3) < LGSIL (4.4) < HGSIL (8.4). Furthermore, results are available from 17 investigations in which MN were scored in smears from patients with neoplasia. MN rates increased with the degree of neoplasia [CIN 1 (4.6) < CIN 2 (6.5) and CIN 3 (10.8)] and were significantly higher (8.8) in CC patients. Our meta-analysis indicates that the MN assay, which is easy to perform in combination with Pap tests, may be useful for the detection/prediction of CC. However, standardization (including definition of the optimal cell numbers and stains) and further validation is necessary before the MN test can be implemented in routine screening.

The 100 Most Impactful Papers in Hand and Upper-Extremity Surgery Over the Last 25 Years: A Bibliometric Analysis

There is no financial information to disclose. Despite growth in hand/upper-extremity investigation, truly impactful studies have not been thoroughly identified. While previous studies were limited in scope of subspecialty and journals, this study sought to identify (by citations) and characterize the most impactful papers in hand/upper extremity over the last 25 years. The top 1,000 cited studies published between 1992 and 2018 related to the hand and/or upper extremity were identified with Thomson ISI Web of Science. Studies were organized in descending order by number of citations, and the title and abstract of each study were screened for relevance. Following exclusion of unrelated studies, the top 100 articles by number of citations were identified and reviewed to identify study type, institutional origin, level of evidence, and journal impact factor. Among the top 100 studies, all were cited at least 100 times, and the mean number of authors and citations were 4.51 and 169.4, respectively. The top 5 study types were case series (n = 52), randomized controlled trial (n = 17), prospective cohort (n = 16), retrospective cohort (n = 8), and basic science (n = 4). The topics covered were mostly commonly related to shoulder (n = 34), wrist/forearm (n = 21), hand (n = 17), and elbow (n = 14). Among shoulder studies, rotator cuff injuries (n = 18) were most frequent, while distal radius fractures (n = 12) were most common among wrist/forearm studies and nerve/nerve repair (n = 10) among hand studies. Most studies were published from institutions originating in the United States (n = 63). The journal that published the most among the top 100 cited was the Journal of Hand Surgery–American Volume (J Hand Surg Am; n = 33), with 5,092 citations 3 among the top 10 (Table 20-1). Mean journal impact factor was 3.29. The majority of studies were of level IV (n = 51) and level II (n = 16) evidence (Figure 20-1). However, the number of level I studies has increased since 1992 (3 in 1992–2006 vs 5 in 2007–2011). The impact of more recent studies is greater, with mean citations per year in 2011 at 82.7/y, compared with 16.1/y in 1992 (R2 = 0.54). •Despite the shorter time frame more recent studies have for impact, mean citations per year have progressively increased over the past quarter century.•The majority of the top 100 articles were published in J Hand Surg Am, were case series, and focused on the shoulder.•While the number of level I studies has increased, the majority were level IV or II, retrospective, and non-randomized studies, emphasizing the call for higher-quality, prospective, randomized trials to bolster our evidence-based practice.Table 20-1The top 10 most cited hand/upper-extremity studies among the top 100 studies, by number of citationsRankTitleFirst AuthorInstitutionJournalYearCitationsStudy Type1The outcome and repair integrity of completely arthroscopically repaired large and massive rotator cuff tearsGalatz LMWashington UniversityJBJS Am2004863Case Series2Treatment of chronic elbow tendinosis with buffered platelet-rich plasmaMishra AStanfordAJSM2006412Prospective Cohort3Reliability and validity testing of the Michigan Hand Outcomes QuestionnaireChung KCUniversity of MichiganJHS Am1998388Case Series4Neer Award 2005: The Grammont reverse shoulder prosthesis: results in cuff tear arthritis, fracture sequelae, and revision arthroplastyBoileau PUniversity of NiceJSES2006355Prospective Cohort5The disabilities of the arm, shoulder and hand (DASH) outcome questionnaire: longitudinal construct validity and measuring self-rated health change after surgeryGummesson CLund UniversityBMC Musculoskeletal Disord2003336Case Series6Functional and anatomical results after rotator cuff repairGazielly DFClinique du DiaconatCORR1994330Case Series7The reverse shoulder prosthesis for glenohumeral arthritis associated with severe rotator cuff deficiency: a minimum 2-year follow-up study of 60 patientsFrankle MFlorida Orthopaedic InstituteJBJS Am2005325Case Series8Fatty infiltration and atrophy of the rotator cuff do not improve after rotator cuff repair and correlate with poor functional outcomeGladstone JNMount Sinai Medical CenterAJSM2007320Prospective Cohort9Endoscopic release of the carpal tunnel: a randomized prospective multicenter studyAgee JMHand Biomechanics LaboratoryJHS Am1992293Randomized Control Trial10Factors affecting functional outcome of displaced intra-articular distal radius fracturesTrumble TEUniversity of WashingtonJHS Am1994292Case Series Open table in a new tab

Eutrophication in aquatic ecosystems: a scientometric study

Abstract Aim: Reveal the direction for future studies about eutrophication, or even reveal the preoccupation among the scientific community about this environmental problem. With a systematic synthesis of eutrophication studies, scientists may be able to understand the state of the literature on aquatic ecosystems around the world. This study intends to identify the main factors used to control algal blooms and the eutrophication process, the countries and environments which have more research about this theme or even identify the articles’ subjects in different periods (e.g.: Experimental, theoretic, monitoring, conservation). Methods We analyzed all studies published in the Thomson ISI Web of Science on both eutrophication and phytoplankton between 2001 and 2016. Results During the period analyzed, we observed an increase in concern about this subject. Authors from institutions in the USA and China wrote most of the studies. The most important geographic and socioeconomic aspects to determine the publication number were total area and HDI respectively. However, the main determinant for the publication about this subject was international collaboration. Some of the most actual themes in ecology and conservation (e.g.: functional groups, climate change, experiment, perdition models, regional scales, invasive species) were addressed in the studies analysed. Invasive species such as Tilapia and Cylindrospermopsis raciborskii were the most cited species on these keywords. Conclusion Despite the current issues addressed in the studies on phytoplankton and eutrophication, some subjects, such as climate change or spatial pattern, were only common in years more recent. Even though studies focusing in functional diversity are highly relevant for conservation, they were not common in any year studied. The major determinant factor related to the increasing in eutrophication knowledge was the international collaboration

Web of Science: Showing a Bug Today That Can Mislead Scientific Research Output Prediction

As in all domains of human activity, economic issues and the increase of people working in scientific research have altered the way scientific production is evaluated as well as the objectives for performing the evaluation. The h index was introduced in 2005 by J. E. Hirsch as an indicator for the measurement of individual scientific output not only in terms of quantity but also in terms of quality, and its use has since spread throughout the world. In 2007, Hirsch proposed its adoption as the best way to predict future scientific achievement and, consequently, as a useful guide for investment in research and for institutions when hiring members for their scientific staff. Since then, several authors have also been using the Thomson ISI Web of Science database to develop their proposals for evaluating research output. Here, using a software we have developed, we analyze more than 100,000 articles and show that a subtle flaw in Web of Science can inflate the results of information collected, therefore compromising the exactness and, consequently, the effectiveness of Hirsch’s proposal and its variations.

The fifty highest cited papers in anterior cruciate ligament injury

IntroductionThe anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics.MethodsThe 50 highest cited articles related to Anterior Cruciate Ligament Injury were searched in Thomson ISI Web of Science® by the use of defined search terms. All types of scientific papers with reference to our topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type and level of evidence.ResultsThe 50 highest cited articles had up to 1624 citations. The top ten papers on this topic were cited 600 times at least. Most papers were published in the American Journal of Sports Medicine. The publication years spanned from 1941 to 2007, with the 1990s and 2000s accounting for half of the articles (n = 25). Seven countries contributed to the top 50 list, with the USA having by far the most contribution (n = 40). The majority of articles could be attributed to the category “Clinical Science & Outcome”. Most of them represent a high level of evidence.DiscussionScientific articles in the field of ACL injury are highly cited. The majority of these articles are clinical studies that have a high level of evidence. Although most of the articles were published between 1990 and 2007, the highest cited articles in absolute and relative numbers were published in the early 1980s. These articles contain well established scoring- or classification systems.ConclusionThe identification of important papers will help current clinicians and scientists to get an overview on past and current trends in that special field of ACL injury and provides a basis for both further discussion as well as future research.

Research Productivity in Development Communication in the Philippines

Pioneered in the 70s by Nora Quebral of the University of the Philippines at Los Baños, Development Communication (DevCom) is now recognized globally as a scientific discipline. As such, it is now a part of the research and development (R&amp;D) agenda of national and international research organizations. For almost four decades, no study has been conducted to find out the research productivity in DevCom in the Philippines. We conducted in-depth analysis on the total number of publications and total number of citations of DevCom publications collected from Thomson ISI database. From the 70s to the present, 74 articles were published. The most dominant domains were on health communication (31.08 %) and agricultural communication (29.72%). On the other hand, the most predominant approaches were social mobilization (44.59%) and behavior change (41.89%). With 74 articles, it can be concluded that research productivity of DevCom in the Philippines is low. This paper presents ways to improve publication performance in DevCom in the country. Future studies may focus on identifying the factors that facilitate or impede publication performance of DevCom researchers and educators.

El factor de impacto de las revistas científicas: limitaciones e indicadores alternativos

Impact Factor measures the average number of times that articles published in the last two years are cited in the current year. In spite of its limitations, the evaluation agencies of some countries like Spain use it in research assessment, generating a deep unease within some circles that consider its use inappropriate and indiscriminate. As an alternative to the Impact Factor of Thomson ISI, other indicators have been proposed, although none of them have achieved sufficient acceptance and widespread use to be systematically applied. Among Spanish initiatives, most notable are the Potential Impact Factor of The Spanish Medical Journals, developed by the Siniac team (Information systems and research activity indicators) from the Instituto de Historia de la Ciencia y Documentación López Piñero (Valencia, Spain), and the Índice de impacto de las revistas españolas de ciencias sociales (In-Recs), developed by the EC3 research group at Library and Documentation department of Granada University (Spain).

Effectiveness of decoronation technique in the treatment of ankylosis: A systematic review.

Dentoalveolar ankylosis in growing patients is complex leading to continuing root replacement resorption, tooth infra-position, or may even affect the development of alveolar ridge and adjacent teeth. While extraction of ankylosed teeth might be associated with bone loss, decoronation of the offending tooth (removal of crown portion and instrumentation of pulp canal to stimulate bleeding) has been suggested as a more conservative approach of bone preservation until definitive implant placement is planned. To primarily assess the efficacy of bone width and height preservation around ankylosed permanent teeth following decoronation. Pubmed, Embase, Ovid Medline, Thomson's ISI Web of Science and Cochrane library were searched from the year 1984 up to May 2015. Two authors conducted the data extraction. To eliminate publication bias, Open Grey literature and Pro-quest Dissertation Abstracts and Thesis database was also consulted. Through our strict selection criteria, only 12 articles were considered for eligibility. No randomized controlled trials were identified. Only one retrospective cohort study, four case series and seven case reports, were analyzed. Following decoronation, preservation of ridge height and ridge width were both noted. To maximize the benefits of decoronation, a timely and wellmonitored intervention is required. Treatment in patients, who have surpassed pubertal growth peaks, may not yield maximum effective treatment outcomes.

Trends and biases in global scientific literature about ecological niche models.

Recently, ecological niche models have been employed to investigate the potential geographical distribution of species. However, it is necessary to analyze the vast number of publications on this topic to understand the trends and biases of research using ecological niche models (ENMs). Therefore, this study aims to investigate trends in the scientific literature regarding studies on ENMs. For the quantitative analysis of the literature on ENMs, we performed a search in the Thomson ISI (Web of Science) database between 1991 and 2013. The search identified 3042 papers containing preselected keywords in either the title or abstract. The results showed that the number of papers has increased over the years (r=0.77, P<0.001), with a sharp increase in recent years, highlighting the widespread use of the ENMs. There was an increase in the diversity of journals that published papers about ENMs (r=0.97, P<0.001). The research was conducted in different countries, predominantly the United States of America (550 papers), and the most commonly used method was the Maximum Entropy method (312 papers). Regarding the taxonomic group, most research has been conducted on plants (402 papers, or 28.36% of the total). There was no relationship between the modeling method used and the taxonomic group studied (χ2=4.8, P=0.15). Finally, the wide availability of biological, environmental and computational resources has elicited the broad use of tools for ENMs. Despite the conceptual discussions of the ENMs, this method is currently the most effective way to evaluate the potential geographical distribution of species, and to predict the distribution under different environmental conditions (i.e., future or past scenarios).

The most cited papers in osteoporosis and related research.

Osteoporosis is a systemic disease of the bone that affects millions of people and causes burden for both the affected individual and health systems and societies worldwide. Since the 1970s much research has been done in the field of osteoporosis. The number of citations of a paper reflects its influence and importance to the field. Thomson ISI Web of Science database was searched to retrieve a list of the fifty most cited articles related to osteoporosis and its research. The fifty most cited articles in absolute numbers in the field of osteoporosis were cited from 877 to 3056 times (mean 1141 ± 537). Most papers were published in the basic science category (n = 23). 395 authors contributed; a single paper had between one and 62 authors (mean: 10.02 ± 9.9 authors). 12 authors (3.04%) contributed between 7 and 4 papers; 340 authors (86.1%) were at least named once. Corresponding authors were from eight countries with most contributions from the United States (n = 34, 68%). The majority of papers were published in the 1990s (n = 29). The list of 50 most cited papers presents citation classics in the field of osteoporosis and related research.
