Abstract  

A new framework of international comparisons is advised: each country is gauged against its bordering countries. This approach has several undeniable drawbacks, but by revealing some otherwise hidden patterns, advantageously supplements the customary comparison methods.

A tudománymetria három sokat emlegetett és idézett törvénye a Bradford-, a Lotka- és a Zipf-törvény. A szerzők röviden bemutatják a három törvény névadójának tudományos pályáját, és hogy hogyan jutottak el a róluk elnevezett törvények megalkotásáig. Vázolják a törvények és névadóik munkásságának utóéletét is. Orv. Hetil., 2016, 157(2), 74–78.

Abstract

The partnership ability index (φ) combines the number of co-authors and the times each of them acted as co-authors with a given author exactly the same way as Hirsch's h-index combines the number of publications and their citation rate. The index φ was tested on the sample of the Hevesy medal awardees. It was found that φ is consistent with Glänzel's model of h-index, and that higher φ values—at least until a certain limit—may be accompanied with higher citation visibility (h-index). Some further possibilities of application both within and outside the area of scientometrics are suggested.

Abstract  

Hirsch’s concept of h-index was used to define a similarity measure for journals. The h-similarity is easy to calculate from the publicly available data of the Journal Citation Reports, and allows for plausible interpretation. On the basis of h-similarity, a relative eminence indicator of journals was determined: the ratio of the JCR impact factor to the weighted average of that of similar journals. This standardization allows journals from disciplines with lower average citation level (mathematics, engineering, etc.) to get into the top lists.

Abstract  

It is shown that a Hirsch-type index can be used for assessing single highly cited publications by calculating the h-index of the set of papers citing the work in question. This index measures not only the direct impact of a publication but also its indirect influence through the citing papers.

Abstract  

It is suggested that h-indices themselves may form the basis of a series of h-indices at successively higher levels of aggregation. The concept of successive h-indices may usefully contribute to develop a coherent frame for multi-level assessments.

Az egyetemek által kiadott folyóiratok jelenleg a tudományos szakirodalomnak egy szerényebb szeletét teszik ki, de számos jele és még több indoka van annak, hogy azt gondoljuk, szerepük növekedőben van. A növekedés ez idő szerint leginkább a társadalomtudományok területén mutatható ki. Az egyetemek folyóirat-kiadási tevékenység szerinti rangsorának élmezőnye néhány nyilvánvaló esélyes (Oxford, Cambridge, Chicago) mellett váratlanabb szereplőket is előtérbe hoz. Orv. Hetil., 2015, 156(16), 650–653.
