[Self-citations: the stepchildren of scientometrics?]. / Önidézetek: a tudománymetria mostohagyermekei?

Self-references, self-citations are considered by some as the sign of vanity, and deemed to be omitted from scientometrics analyses. In fact, self-citations reveal information in the study of scientific communications that is different but not less valuable than citations received from others. In the practice of self-citation severe ethical issues may emerge that can be bandled by the co-operation of the authors, editors and publishers. Orv. Hetil., 2016, 157(32), 1289-1293.

[Apples with oranges? Comparison of scientometric indicators between fields]. / Almát a körtével? Tudománymetriai összehasonlítások szakterületek között.

It is well known that all scientometric indicators strongly depend on research fields. Therefore, there is a certain reluctance to make any cross-field comparison of these indicators. The paper reviews the possibilities to normalize the most important scientometric indicators: publication counts, citation rate or h-index, thus making them suitable for cross-field comparison.

[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.

[Law-making "pioneers" of scientometrics]. / A tudománymetria törvényalkotó "úttöroi".

The three much cited laws of scientometrics are the laws of Bradford, Lotka and Zipf. The authors briefly review the scientific career of the men behind the names, and that how they discovered the laws named after them. An outline is also given of the scientific aftermath of the laws and of the oeuvre of their eponym.

[Is there protection against copying? Thoughts about plagiarism]. / Van-e védelem a másolás ellen? Gondolatok a plágiumról.

There are at least two reasons why more and more cases of suspected plagiarism are perceived in the scientific literature. On one hand, the ever increasing pressure for publication makes it easier for authors, reviewers and editors to infringe or overlook this serious ethical misdemeanor; on the other hand, with the development of text analysis software, detecting text similarities has become a simple task. The judgement of actual cases, however, requires well-grounded professional knowledge and prudent human decisions.

[Beyond the impact factor. Reflections on the book of Stefanie Haustein]. / Túl az impaktfaktoron. Gondolatok Stefanie Haustein könyve nyomán.

The excellent book on multidimensional journal evaluation by Stefanie Haustein helps to find the place of the impact factor in the complex system of journal evaluation indicators. By delimiting the dimensions of evaluation and the user groups, the author of the book creates a framework that serves as a novel and useful guidance both for the lay reader and the expert.

[Case and studies]. / Esetek és tanulmányok.

Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

[Webometrics ­ on the occasion of the awarding of the Derek John de Solla Price Medal, 2015]. / A webometriáról - a 2015. évi Derek John de Solla Price-emlékérem odaítélése alkalmából.

The most significant recognition in scientometrics, the Derek John de Solla Price Medal was awarded in 2015 to Mike Thelwall. Thelwall is a dominant personality in webometrics studying the internet presence of scientific research with quantitative methods. In this paper the emergence, standing and directions of webometrics are briefly reviewed.

[How to rank if you must? Reflections on the book of Amy N. Langville and Carl D. Meyer]. / Hogyan rangsoroljunk, ha muszáj? Gondolatok Amy N. Langville és Carl D. Meyer könyve nyomán.

More than ever, our life is permeated by rankings. This is true also in the world of scientific research. The responsibility of the producers of such rankings is significant, since their results may influence decisions determining human fates and careers. The reviewed book - in a rather special area of ranking only - exemplifies how a set of methodologies can be systematically compiled, and how various methods can be combined into comprehensive, multidimensional rating and ranking systems.

[The impact factor and those who dislike it]. / Az impaktfaktor és akiknek nem kell.

Since its introduction in 1976, the impact factor is permanently a subject of both criticism and glorification. This paper gives an overview on what actually the reservations and objections attack. A closer look often reveals that the criticisms are not against the specific substantial features of the impact factor. They may formulate much more general doubts or, on the other hand, superficial technical details, easily remediable flaws or inconsistensies resulting erroneous use.

[Significance of journal articles within the scientific literature of various disciplines: trends over the past two decades]. / A folyóiratcikkek súlya a különféle tudományterületek szakirodalmában: az elmúlt két évtized trendjei.

Trends of preferred publication channels in selected categories of Sciences, Social Sciences and Arts & Humanities were studied by determining the percentage share of references in reviews to serials (journals) in all references. It was found that in the period 1995-2014, the fraction of articles published in journals was increasing in all selected areas of science and scholarship. The most dynamical increase was found in Social Sciences.

[Actors of journal publishing in the social and medical sciences]. / A folyóirat-kiadás szereploi a társadalom- és orvostudományokban.

Journals published by universities take up a modest part of the scientific literature at the moment, but there are several signs and even more reasons to believe that their significance is rising. Recently, the most significant increase can be detected in social sciences. The top list of university rankings based on journal publishing activity brings into the forefront - beside some obvious favorites (Oxford, Cambridge, Chicago) - some less expected universities, as well.

[Information flow between medical and social sciences]. / Információáramlás az orvosi és a társadalomtudományok között.

In order to reveal impacts of natural and social sciences on each other, the authors examined connections between fields of medical and social sciences using a search for references and citations of scientific publication. 1. The largest affinity between the medical and social sciences was found between neurosciences and psychology, but there was a significant affinity between clinical sciences and general social sciences, as well. 2. The example of General & Internal Medicine papers in the topics of "diabetes" suggests that in the period 2001-2010 the share of references to social sciences was significantly increased. In the meantime, social science papers in the same topics contained references to Clinical Medicine papers in a constantly high percentage. 3. In the sample under study, the age distribution of social science papers in the references did not differ significantly from that of the other sources. 4. Share of references to social science papers was found to be extremely high among Hungarian General & Internal Medicine papers in the topics of "diabetes". This finding still requires clarification, nevertheless, since e.g. it was not supported by an institutional comparison including the largest Hungarian medical research university. 5. The intensity of the reference/citation mediated information flows between the Hungarian Medical Journal, Orvosi Hetilap and social sciences appears to be in accordance with the current international trends.

[Literature of so-called "clinical research": structure and trends, 1991-2010]. / A klinikainak nevezett kutatások szakirodalmának szerkezete és irányai, 1991-2010.

The authors studied trends and patterns in the literature of research labeled as clinical (i.e., having the word "clinical" in their title) in the period between 1991 and 2010. The main findings are: 1. The growth of the literature under study was somewhat stronger than that of the overall medical literature. 2. The dominance of the USA is strong but is challenged by some of the most rapidly developing countries (particularly in the Far-East region: China, Korea) in total production, and by the developed European countries in highly cited publications. The eminence of Italy is remarkable. 3. In comparing the medical fields, the most striking tendencies are the increase of oncology and the attenuation of internal medicine. Surgery is steadily growing in size but decreasing in its citation influence. 4. Word frequency studies support the ever growing weight of oncology and also of genetics. 5. Beyond the thematic changes, word frequency studies also reveal a substantial change in attitude: in the period under study more and more effort was made on emphasizing the usefulness, efficiency and risks of the results in contrast with the more descriptive, investigative approach of the past. The role of therapy is growing, the role of diagnostics is decreasing. The knowledge of these trends and patterns may orient health and science policy makers to cope appropriately with the ever changing world of clinical research.

[The literature of diagnosis and therapy]. / A diagnózis és a terápia szakirodalma.

This analysis is based on papers published in periodicals, in the period 1975-2013 with title words referring to diagnosis or therapy. The literature of both topics is growing dynamically and in an ever accelerating pace. At the same time, the two topics appear to get more and more separated, except for a part of the German-language literature. The share of therapy-oriented literature is increasing and its citation rate is higher, although 9 of the 10 most cited papers are from the topic of diagnostics. The Hungarian literature (papers having at least one Hungarian author) appeared to be proportional and balanced.

[Scientometric aspects of medical eponyms]. / Orvostudományi eponímák tudománymetriai nézopontból.

Eponyms, scientific concepts named after persons, have a long tradition in medical sciences. Their emergence and use are rather instructive from the aspects of scientometrics, as well. Using a medical sample it is shown that although references to publications giving origin to the eponyms inevitably get obliterated, their citation rate is still many times higher than that of other publications of the same age.

[The Orvosi Hetilap (Hungarian Medical Journal) in the network of medical journals]. / Az Orvosi Hetilap az orvosi folyóiratok hálózatában.

The role of networks is swiftly increasing in the production and communication of scientific knowledge. Network aspects have, therefore, an ever growing importance in the analysis of the scientific enterprise, as well. The present paper demonstrates some techniques of studying the network of scientific journals on the subject of seeking the position of Orvosi Hetilap (Hungarian Medical Journal) in the international journal network.

A chemistry field in search of applications statistical analysis of U.S. fullerene patents.

The paper is examining the U.S. patenting activity on the application of fullerenes and shows that despite some pessimistic manifestations in this respect in the current literature there are many promising approaches regarding the pragmatic aspects of this field of chemistry.
