ZusammenfassungWissenschaftliche Leistungen leben von der Originalität ihrer Urheber. Der Ver-such, sie zu quantifizieren, erscheint als Widerspruch in sich. Um so irritierender ist der Siegeszug des sogenannten Impact Factors, eines Konstrukts des amerikanischen Institute of Scientific Information (ISI), das den Anspruch stellt, über die Häufigkeit der Zitierung von – vom ISI erfaßten – Zeitschriften das Gewicht der in diesen publizierenden Wissenschaftler zu messen. Seit naturwissenschaftliche und medizinische Forschungseinrichtungen und Fakultäten dazu übergehen, den Impact Factor zur Grundlage für die Verteilung von Forschungsgeldern und zur Guillotine für wissenschaftliche Karrieren zu machen, schickt er sich an, die internationale Wissenschaftskultur zu verändern. Deshalb ist es an der Zeit, daß die Öffentlichkeit dieses Zeitgeistphänomen zur Kenntnis nimmt und sich mit seinen Folgen auseinandersetzt.

This chapter discusses how performance is measured in science, such as through the role of citation metrics. Next, the chapter discusses the pros and cons of bibliometric indexes, and of ‘impact factor’, which was introduced by Eugene Garfield in 1955 but not widely used until twenty years later. The various ways that journals attempt to improve their impact factors, and how this will affect science, are also examined. Besides impact factor, the role played by indicators in evaluating scientists, such as the recently introduced h-index, is explored. Finally, fashions and trends in science are touched upon, illustrated with personal anecdotes from the author.

This study analyzes the journal impact factor and related bibliometric indicators in Education and Educational Research (E&ER) category, highlighting the main differences among journal quartiles, using Web of Science (Social Sciences Citation Index, SSCI) as the data source. High impact journals (Q1) publish only slightly more papers than expected, which is different to other areas. The papers published in Q1 journal have greater average citations and lower uncitedness rates compared to other quartiles, although the differences among quartiles are lower than in other areas. The impact factor is only weakly negative correlated (r=-0.184) with the journal self-citation but strongly correlated with the citedness of the median journal paper (r= 0.864). Although this strong correlation exists, the impact factor is still far to be the perfect indicator for expected citations of a paper due to the high skewness of the citations distribution. This skewness was moderately correlated with the citations received by the most cited paper of the journal (r= 0.649) and the number of papers published by the journal (r= 0.484), but no important differences by journal quartiles were observed. In the period 2013–2018, the average journal impact factor in the E&ER has increased largely from 0.908 to 1.638, which is justified by the field growth but also by the increase in international collaboration and the share of papers published in open access. Despite their inherent limitations, the use of impact factors and related indicators is a starting point for introducing the use of bibliometric tools for objective and consistent assessment of researcher.

Microscopy and Microanalysis has made significant strides forward over the past year, and I would like to comment on two of these. First, the Institute for Scientific Information (ISI) ranked this journal third among the nine microscopy journals it indexes. The ranking was in terms of ISI's Impact Factor, which tracks the number of citations to papers published in the journal. A strong Impact Factor indicates that information in the journal is of interest to other workers in the field. Second, the National Library of Medicine (NLM) has selected Microscopy and Microanalysis to be indexed in MEDLINE (PubMed), beginning with the first issue of 2003. As any biologist will tell you, this listing is essential for the electronic visibility of papers in the fast-moving world of life sciences research. I thank Editorial Board member Dave Piston for his efforts in writing the initial letter of application to the NLM.

The primary goal of Laser and Particle Beams as part of the Cambridge University Press is the dissemination of knowledge in our research field. How effective we are in this respect is not easy to determine. But the impact factor published annually in June by Thomson ISI® 2005 Journal Citation Reports (JCR), gives at least an indication and a method to compare other journals in the field. In this respect, Laser and Particle Beams is a journal with a very high ranking in the field of applied physics, but it also compares very well to journals in other field of physics. The impact factor of a journal gives an account of how often an average paper in the journal is referred to, in a two year time span after publication. The current impact factor of 2.59 is based on an evaluation conducted in 2005 of Laser and Particle Beams publications of 2003 and 2004. During the evaluation period (2005), Laser and Particle Beams publications were cited about 1000 times. The topics that attracted most attention were Fast Ignition (Deutsch, 2004; Mulser & Schneider, 2004a; Hora, 2004; Mulser & Bauer, 2004b), Inertial Fusion Targets (Borisenko et al., 2003), and Ion and Electron Acceleration in laser plasma and Ultrashort Pulses (Shorokhov & Pukhov, 2004; Osman et al., 2004; Malka & Fritzler, 2004; Limpouch et al., 2004; Pegoraro et al., 2004). However, the editorial boards of Laser and Particle Beams strongly encourage authors to submit their results in High Energy Density Physics, the emerging field of Warm Dense Matter, Pulsed Power and Accelerator Physics and Technology.

News of the death of biomedical journals seem premature. Revamped traditional scientific journals remain highly valued sources and vehicles of information, critical debate, and knowledge. Some analyses seem to place a disproportionate emphasis on technological and formal issues, as compared to the importance ascribed to matters of power. Not all journals must necessarily have a large circulation. There are many examples of efficient, high-quality journals with a great impact on relatively small audiences for whom the journal is thought-provoking, useful, and pleasant to read. How can we achieve a better understanding of an article’s spectrum of impacts? A certain mixing of three distinct entities (journals, articles, and authors) has often pervaded judgments. Data used by the Institute for Scientific Information present weaknesses in their accuracy. The two-year limit for citations to count towards the bibliographic impact factor favors "fast-moving", "basic" biomedical disciplines and is less appropriate for public health studies. Increasing attention is given to the specific number of citations received by each individual article. It is possible to make progress towards more valid, accurate, fair, and relevant assessments.

Following up on recommendations from OSI 2016, this team will dig deeper into the question of developing and recommending new tools to repair or replace the journal impact factor (and/or how it is used), and propose actions the OSI community can take between now and the next meeting. What’s needed? What change is realistic and how will we get there from here?

A small, self-selected discussion group was convened to consider issues surrounding impact factors at the first meeting of the Open Scholarship Initiative in Fairfax, Virginia, USA, in April 2016, and focused on the uses and misuses of the Journal Impact Factor (JIF), with a particular focus on research assessment. The group’s report notes that the widespread use, or perceived use, of the JIF in research assessment processes lends the metric a degree of influence that is not justified on the basis of its validity for those purposes, and retards moves to open scholarship in a number of ways. The report concludes that indicators, including those based on citation counts, can be combined with peer review to inform research assessment, but that the JIF is not one of those indicators. It also concludes that there is already sufficient information about the shortcomings of the JIF, and that instead actions should be pursued to build broad momentum away from its use in research assessment. These actions include practical support for the San Francisco Declaration on Research Assessment (DORA) by research funders, higher education institutions, national academies, publishers and learned societies. They also include the creation of an international “metrics lab” to explore the potential of new indicators, and the wide sharing of information on this topic among stakeholders. Finally, the report acknowledges that the JIF may continue to be used as one indicator of the quality of journals, and makes recommendations how this should be improved.OSI2016 Workshop Question: Impact FactorsTracking the metrics of a more open publishing world will be key to selling “open” and encouraging broader adoption of open solutions. Will more openness mean lower impact, though (for whatever reason—less visibility, less readability, less press, etc.)? Why or why not? Perhaps more fundamentally, how useful are impact factors anyway? What are they really tracking, and what do they mean? What are the pros and cons of our current reliance on these measures? Would faculty be satisfied with an alternative system as long as it is recognized as reflecting meaningfully on the quality of their scholarship? What might such an alternative system look like?

One of the most fundamental issues in academia today is understanding the differences between legitimate and predatory publishing. While decision-makers and managers consider journals indexed in popular citation indexes such as Web of Science or Scopus as legitimate, they use two blacklists (Beall’s and Cabell’s), one of which has not been updated for a few years, to identify predatory journals. The main aim of our study is to reveal the contribution of the journals accepted as legitimate by the authorities to the visibility of blacklisted journals. For this purpose, 65 blacklisted journals in social sciences and 2,338 Web-of-Science-indexed journals that cited these blacklisted journals were examined in-depth in terms of index coverages, subject categories, impact factors and self-citation patterns. We have analysed 3,234 unique cited papers from blacklisted journals and 5,964 unique citing papers (6,750 citations of cited papers) from Web of Science journals. We found that 13% of the blacklisted papers were cited by WoS journals and 37% of the citations were from impact-factor journals. As a result, although the impact factor is used by decision-makers to determine the levels of the journals, it has been revealed that there is no significant relationship between the impact factor and the number of citations to blacklisted journals. On the other hand, country and author self-citation practices of the journals should be considered. All the findings of this study underline the importance of the second part of this study, which will examine the contents of citations to articles published in predatory journals because understanding the motivations of the authors who cited blacklisted journals is important to correctly understand the citation patterns between impact-factor and blacklisted journals.

Academic economists appear to be intensely interested in rankings of journals, institutions, and individuals. Yet there is little discussion of the uncertainty associated with these rankings. To illustrate the uncertainty associated with citations-based rankings, I compute the standard error of the impact factor for all economics journals with a five-year impact factor in the 2011 Journal Citations Report. I use these to derive confidence intervals for the impact factors as well as ranges of possible rank for a subset of thirty journals. I find that the impact factors of the top two journals are well defined and set these journals apart in a clearly defined group. An elite group of 9–11 mainstream journals can also be fairly reliably distinguished. The four bottom ranked journals are also fairly clearly set apart. For the remainder of the distribution, confidence intervals overlap and rankings are quite uncertain. (JEL A14)
