Fig. step 1 portrays new visibility of your own record inside Scopus (just like the 1973) and in SCIE (once the 2009). 4%), a mean away from 207 annually. Coverage during the Scopus could have been uneven, that have highs out of almost five-hundred really works (including when you look at the 1998, considering the introduction off dos tablets, among them which have 205 documents) and designated troughs (including the 152 files secure during the 1994). Inside the SCIE, the brand new visibility could have been more consistent, although there has been a reducing development, into the number of integrated files losing regarding 250 last year so you’re able to 160 in the 2017.

Whether or not it came to file coverage, we located discrepancies within 2 databases from the shipments from the latest 4 types of records involved. This new proportion out-of stuff are 74% during the Scopus vs 46% when you look at the SCIE, new ratio out of letters 16% versus 38%, that editorials step 3% compared to 16%, and also the ratio from ratings seven% against 0.54% (Fig. 2).

Within the Scopus, really stuff had been signed by the 5 (19%) or six authors (18%), reviews by step 1 (twenty seven.4%) otherwise 2 (fifteen.4%), letters by cuatro (31.5%) otherwise 5 (23.1%) and you may editorials from the step 1 (53.3%) or dos (twenty six.8%).

The common level of people of multiple-created records from inside the Scopus within the whole several months not as much as studies was 4.4. Minimal is actually 2.5 from inside the 1974 and restriction 5.8 during the 1995 and you will 2007 (Fig. 3). 7) and has now already been treating before number of years, attaining the establish 5.one in 2017.

6 from inside the 1996 to 3.dos from inside the 2017. The fresh new peak took place 2007 (step 3.7). The average for the whole months below research is actually out-of dos organizations per really works. There are 1164 data versus a state association, and of the rest 8694 records, 57% don’t include collaboration anywhere between associations. This new part of really works you to inside it global cooperation about 2009-2017 period try cuatro.2%.

It index (so you can 4

Fig. 4 merchandise the new circle of collaborations ranging from Spain and other nations. So you’re able to span the longest you’ll several months on the analysis, we decided to merely area the latest system regarding collaborations of analysis taken from the brand new Scopus databases, within the several months off 1996 (the season that Scopus already been gathering affiliation analysis per publisher) so you can 2017. Within this period, we discover collaborations that have 41 countries, having no less than 2 collaborations getting 26 of them regions. The brand new nations with worked most often which have Spain was basically the latest Us (42 performs), Mexico (15), Italy (14), Uk (11) and you will Portugal (9).

Table step one gift suggestions the prices of one’s total number away from data files, final number off citations, admission speed for every file and you may h -index. It is instantaneously obvious that violation indices try high during the Scopus. For example, getting 2015 since site, since it is a year which one another database possess listed a comparable quantity of articles (217), the admission matter within the Scopus (619) exceeds from the 234 the number of citations obtained from the SCIE (385). Ergo, because level of noted records is quite comparable in sources, an average number of citations for each document is leaner about SCIE database (2.27 inside Scopus against step one.5 on SCIE). Similarly, the common h -list are 18 for the Scopus compared to 14 regarding the SCIE.

The common amount of collaborating institutions per work has actually moved on from dos

Desk 2 gifts the values into the main pass indicator in Scopus additionally the SCIE. Both impression factor plus the SJR has actually improved just like the log are used in JCR and Scopus. Throughout the SCIE, the effect foundation has increased 4 times throughout the 9 decades Anales might have been detailed. It index changed off 0.363 in ’09 to a single.318 inside 2017 and you can continues on an ever-increasing pattern. Therefore, brand new log ranks comes with changed quartiles, swinging regarding the fourth towards third quartile in the 2016. For the Scopus, brand new SJR changed of 0.155 in the 1999 to help you 0.277 in the 2017. Although not, if we become familiar with its progression as 2009, in the event that diary was as part of the SCIE, it sign has not yet improved as much as the fresh new effect grounds (out of 0.235 so you can 0.277). On SCIE, the impression basis is served by increased four times leaving out care about-citations, once the 5-year feeling grounds has grown from the a very important factor out of 2.six.
