InCi t es pro vi d es six furt he r schemes, e.g. t he 22 su bject areas provi d ed by Tho m so n Reuters in t he Esse ntial Sc ienc e I ndicators. A concordan ce t able between t he OECD cat egori es a nd t he WoS subjec t categori e s is a ls o provi ded (at htt p://i nc i t es. isiknowle dge.co m/comm o n/help/h_fie l d_cat egor y _o ecd.ht ml) . As against the ot he r schem es, t he OECD schem e all o w s f o r t he use of six bro ad subj ect areas for WoS da ta: (1) na tur al sc ien ces, ( 2) en gineering and techno l o gy , (3) m ed ical and heal t h sciences, (4) agr i cu l t ura l sc ience s, (5) soci al sciences, and (6) hum ani t ies. Each subjec t area incor porates sub o r dina te fi e lds. Since bibli o metr i c t rend an a lyses requ i res sufficient publicat i o n numbe r s f o r each co untr y in each publication year, we co nsi dered o nl y the t hree m ain subject areas: (i ) na tur al sci ences, ( ii ) engineering and techno l o g y , and (iii ) medical a nd heal t h scienc es. Us in g t hese t hree subj ect areas, the countr y dat a (In C i t e s TM Tho m son Reuters 2012) were do wnl o aded as an Exc el sheet and im po rt ed in to St a t a (S t a taCorp. 2013) for stati st i ca l an alys is . Accordin g to Marsh a ll & Travis (2011) and Adams (2010), Thomson Reuters cal cu lates t he m ean ci tat i o n rat e for a c ountr y’ s set of publi c at i o ns and then d ivide s t his ci tat i on score by t he mean o f all t he publications ( in t ha t subj e ct area). A v a lue of 1 for a specifi c countr y ( in a specifi c subject area) in d icates t ha t t he ci tat io n im p act of papers publish ed by scient i sts in t his country is t he same as t he worl dw ide average im p act of papers ( in t hi s subject area). For exam p le, if t he nor m a lized value adds up to 1.2, the correspondin g papers were cited on av erage 20 percentage po ints above t he average (in the subj e ct area). Al t hough the divisi o n o f mean s does not provi de a pro per st atis t ic (Opt hof & Leydesdorff 2010; Gin gr as & Lar iviè re 2011), i t can be consi der ed to use the se n or m a lize d c i t at i o n impac t val ues at t he hi gh level o f aggregat i o n o f countr i es (base d o n seve ral hundreds of publica t ion s). 7 Spear m a n’s ran k -o rder c oefficient (r s ) for the correlat i o n between publicati o n yea r a nd t he numbers of publi cat i o ns as well a s c i t at i o n impact are cal culated f o r each co untry (Bor nm a nn & Leydesdo rff 201 3 ; Sheskin 2007). The coe ff ici ents suppo rt t he in t erpr etation o f t he trend resul t s bey o nd visual inspect i o n o f t he curves : a po s i t ive coefficien t indicates an inc reas in g t rend in t he countr y ’s c i t at i on impact or publi c at i o n o utput, respectiv ely, acro ss t he publica t ion years, while a n egat iv e coe fficien t sh o ws a decreasin g t r end. To m easure the va r iabili t y o f ci t at i on im pa ct val ue s acro ss the publi cat i o n years, t he stan dard deviati o n (SD) is calculated in the time series for each country a nd e ach subject area ( see Tabl e 2). Thi s standard devi at i on in d icat es the extent o f deviat i o ns f r o m t he m ea n o f a co untry ’ s citation impac ts acro ss all publicat i on y e ars. A re l at iv e ly small standard devi at i on, for exam p le, indic ates t hat t he se im pact val u es do not devi at e fro m t he m ea n across all years to a l arge ex tent. Wh at sh o u l d be n o t ed here are m ethodo l og i cal concerns related to the da t abases used.

We decided to show the productivi t y and citation impact numbers f o r t he m e mber stat es separately , but incl uded t he USSR in the co -authorshi p re l at i o ns.

In 2011, 3,744 j o ur n a ls were incl uded in SCI as against 8,336 journals in SCI - E. Data for t he y e ars 1990, 2000, and 2011 were downl oaded a nd organised in a re l at i o nal data bas e (see T able 3). Co-authorshi p re lati o ns am o ng countr i e s are co unted on the basis o f in t eger countin g, but o nly o nc e. In ot her w or ds, i f a paper co ntains 3 addresses in countr y A and 2 in co untry B, t hi s is considered as a s in g le co -authorshi p re l at i o n (and not as six ) . The asymme t ri c a l ( 2- m o de) matr ix o f docu m e nts versus countr y names is transf o r me d in t o a symm etr ic al co -authorshi p matrix using Pa jek v3. A detail ed analysis o f t he gl o bal ne two rk in 2011 is pro vi ded by Leydesdorff, Wa gner, P ark & Adam s (2013); see also Leydes do r ff & Wagner (2008) and W agner & Leydesdorff (2005 ). The mem bers o f t he EE countr i es were assigned (w i t hin Pa jek) to a fi r st parti t ion ; t he ten m o st pro lif ic co untr i es in each y ear (o n the basi s o f bot h in t eger and fract i o na l count in g) were assi gned t o a second part i t i o n (e. g.

T h ese co untri es accessed t he EU in 2004 and 2007. For Ukrain e, a not i ceable decrease in t he n u mber o f publicat i o ns w as o bse r ved in t he ye ars 1991-1993; since t his t im e, t he n u mb er o f pu blicat i o ns has not yet reach ed t he l e vel o f t he 1980s . The ci t at i o n im p act of the EE countri e s is smalle r t han the wor l d average (which is represen t ed by t he value o f 1), both for sci e nc e in gene ral (Figure 1 , Tabl e 2 ) and f o r t he diff erent subj ect ar eas consi d ered (Figure 2, T abl e 2) . However, an increasi ng t rend coul d be observ ed f o r t he ci tat i o n impact rel at iv e t o t he worl d f o r all t he EE countri es (F igure 1) , 10 sugges t ing that in sev era l years at l ea st som e o f the EE countri es can be expected to hav e a ci tat i on im pa ct l arger t han t he wor l d average.

There was hard ly any co ll a borat i o n between S l o vakian an d Russia n resea rchers. In 1990 Hungarian scientis t s scarcely co ll aborated wi t h t he USSR’ s, an d in 2000 t hey scarcely collab or at ed wi t h t hose in Russ ia; t hi s changed in 2011, when an inc rease in t his coll aborat i on was o bse r ve d.

But in two other countri es , t he level o f in ternat i onal co llab or ati o n wi t h other EE countri es increased: Po l a nd (wh ose r esearche rs also coll a borat ed cl o se ly w i t h Russi a, t he Czech Republic an d Ukra ine, b ut als o qu i t e c l ose ly w i th Hu ngary a nd Rom ania) an d t he Czech Republic ( m ainly w i t h Polan d, Russia, S l o vakia, but also qui te cl ose ly with Hun gar y). Co ll a borat i o n between researchers from Rom a nia and Hun gar y, an d f r o m Russia an d Bulgar ia was negligibl e ( and is not represen t ed in the Figures 3c a nd 4c). Tak in g non-EE countri es also in t o acco unt, res earch ers fro m m o st of t he EE countri e s m o st ly co ll a borated wi t h author s in t he USA (Figure 4a- c) , parti cu larly Russia, Po l a nd, and Hun gar y . Co llab or at i o n between the EE rese arch er s and t hei r UK co lle agues was m uc h weaker t ha n w i t h t hose f ro m t he USA , which – as the leading scient if ic count r y – i s t he m ost in t erest ing co ll a borati on part ner f o r a ll na t ions . Anot her im po rt ant c ount ry in terms of scientifi c co ll abor ati on w i t h researchers f ro m t he EE countri es in 2000 and 2011 was Germany , as coul d be obse r ved es pecially for t he Czech Republic, Po l a nd, Sl o vak ia, but also f o r Rom ania and Bulgar ia (Fi gure 4 b- c). 12 Coll aborat i on a m o ng researchers f ro m t he EE and Western co untri es seems to be simil ar in 1990, 2000 and 2011 (Fi gures 4a- c). Take Rus sia: i t s co ll a borat i o n w i t h t he USA was m or e effi cient (in terms of n u mber o f co - au t hored papers ) in 2000 t han t hat be t ween USSR and USA in 1990, but t hen again , i t was le ss in 2011 t han in 2000. Russia’s coll abor ati on w i th t he UK in 2000 was s imil ar to th at in 2011, but both were sli ghtly stro nger t ha n t hat between t he USSR and t he UK in 1990. Polan d’s co ll a borat i o n w i t h t he USA in 2000 and 2011 was sli g ht ly st ronger than t hat in 1990, but one mi g ht expect a grea t er diff erence. Thes e are j ust t wo exam p les, but clearly no boo s t o f in t ernat i o nal co llab or ation was observed for any o f t he present EE c ount ri es – rather a small increase o r ev e n a l ack of any not i ceable c han ge. Al t hough the number of publi cat i o ns by aut hors f r o m Russia was slig htly larger in 2011 than in 2000 and citat i on im pact s were gr eater in 2011 t han in 2000 (F igure 1), co ll a borat i o n o f Russian researchers wi t h t hose f rom ot her countri e s in 2011 was le ss in t e nsi ve t han in 2000 ( Figures 4b -c). Russi a ba ses i t s science sys te m o n i ts o wn inf r ast ructure, know- how and personn e l , w i t h o nly weak co -author shi p re lat i o ns w i t h ot her countr i es. T his appro ach resu l t s in pu bli c at ion perfo rm a nce which is st able but not in creas in g : t he number of papers w i t h Russian addresses has not chang ed since 1981, and the normali z ed ci tat i on im pa ct i s one o f t he l o west am o ng the EE co untri es despite a co mm on o p ini o n that Russi an science is very stro ng. 4 Discussion Our m ain research quest i o n was w hethe r the breakdo wn of the c ommunis t reg im e affected publi cat i o n per f or m a nce in t er m s o f papers publishe d in j o ur nals indexed in WoS as well as in inter na t iona l co ll a borat i o n by researchers f ro m t he EE countri es wi t h t hose o f t he W est ern countr i es. Base d o n the li terat ure one mi g ht expect that t h e ans wer to this quest i o n sh o u l d be posit iv e. For som e o f t he EE countrie s (Bulga r ia, t he Cze ch Republi c a nd Sl ovak ia, 13 Hun gar y , Po l a nd an d Ro m ania) a n in crea se in inter na t ional co -aut horshi p re l at i o ns was observ ed after 1989 (Teodorescu & A ndrei 2011). The pos i t ive answer might als o be sugges t ed by co mm o n know l edge o f the recent histo ry and socie ta l de vel o pment in t he EE countr i es after t he break down of the comm unist regime . Take Pol and, f or exam p le: opening i t s borders to the W est ern countries ga ve r i s e to quic k econo mic de vel o p men t, bu t als o condi t i o ns for scien t ifi c devel o p ment improved. Coll aborat i ons w i t h Western colleagues start ed to b e accepted ( if not wel co med) by universi t y author i t ies , universi t ies ga in ed much m o re auto nomy fro m t he go v ernment, acces s to We stern li t erat ure was acqui red, o ffi c ial but ill o g ic al a nd quasi - scient if ic ideas an d parad igms (such as t ha t of ly s enko i sm; Gra ham 1974) d i d not bl o ck t he devel o p ment of scien ce, and the li ke. T he pic tur e of Po li s h sc ien ce in the last years of the twen t i eth centur y wa s co m p lete ly d ifferent f ro m t hat during the 1980s. The si t uat i o n o f f o rm er USSR st at es was m uc h m o r e compl e x and difficul t t ha n t hat of Po l a nd. Wh en t hey beca me in d ependent, they a ls o l o st suppo rt f ro m t he USSR, which actually was t he main source o f kn o w l edge a nd f u nd ing f or sci ence and techno l o g y . Fast decentrali sat i o n wit hout an appropri at e p l a n can be dange ro us, caus in g t he who l e sc ien t ifi c system to be crushe d. Pract i ca lly a ll for m er So vi et countr i es suffered from a decrease in funds f o r research and de vel o p men t , som e of which (e.g. Georgia) were dram at i c (Yego rov 2009). For these reasons , science de vel o p ment in t he f or mer USSR states st udi ed in t his paper (Ukraine, Bel ar us and Mo l do va) was sl ower t ha n that in the other EE countri es, includin g a sl o wer devel o pment o f a network o f in t ernati ona l co llab or ators wi t h t he Wes t ern countries wi t h strong scientifi c o utput. In sum , po li t ical o pening of borders between the EE and Western co untri es might inde ed lead to an increas e in in t er na t ional co ll a borat i o n a m o ng researche rs f r o m t he EE and W est ern countr i es. However, this mi g ht be acco mpani ed by de creased in t ernat i ona l coll abor ati on a m o ng t he resea rchers f ro m t he EE countr i es. Our li ne o f thinking was as 14 f o ll o ws: dur in g t he So vi et period, r esearch ers f ro m the EE countri es co ul d co ll aborat e wi t h researchers f ro m t he ot he r E E coun tr i e s, and in many si t uat i o ns co - authorship rel at i o ns w i t h Russi a was even expected. T hus , whil e in t er nat i o na l co ll a borati o n w i t h ot her (especi a lly W est ern) countri e s was hindered and in many cases even impossibl e, in t er na t ion al coll abor ati on a m o ng t he EE countrie s in t he f or mer Warsaw Pact was possibl e and so m et im es f o rced. The drasti c change in t he poli t ical si tuat i on w hich a ll t he EE c ountri e s underwent a f ter t he breakdown of t he comm u nist r egim e might have g iv e n r i se t o a chan g e in sci ent ifi c coll abor ati on patt erns: wha t was so dif ficul t and even f o rbidden bef o re ab andoning t he comm unist rul e was now a ll o wed (a l t hough st ill not necessarily simple). Wh at i s m o re, one kne w t hat the W e st ern scien t is t s pro duced m o re papers, whi c h were m o re frequent ly c i t ed, an d so m a ny researc he rs might have been willing to f o ll ow t he W e stern standards instead o f t he Sovi et ones. All t he se fa cts suggested t h at in t ernat i o nal co - au t horshi p re lat i o ns a m o ng researchers f ro m t he EE and Western co untri es s hou l d ha ve in crea sed, while among researchers f ro m t he EE countr i es t hat was not nece ssa r ily t he case. From o ur r esearch i t does n ot neces sarily f o llow t hat answe r in g t he resea rc h ques t i ons f o r m ulated at the en d o f t he in t r oduction sect i on is sim p le: t he si t uat i o n is m o re complex a nd countr y -spec ific. The number of papers publi s hed by re searchers affiliated to ins t i t ut i o ns l o cated in m ost of the EE countri es d id not in cr ease; signifi c a nt in creases were o bs er ved f o r t w o co untri es o nly – t he Cze ch Republi c a nd Poland. For som e o f t he ot her c ountr i es (such as S l o vakia and Romania) not i cea ble chan ges have been observed o nly recent ly (dur in g t he recen t 5-7 y ears). Escapin g co mm u nist r ul e d i d not seem to ha v e t oo great an im pa ct on t he scientifi c per f o r man ce in these countr i e s. For Ukr ai ne t he si t uat i o n was even th e o pposi t e – after becomi ng an in dep e nden t countr y , Ukra ini a n resea rc he rs published f ewer articles in WoS j o urnals, an d t he n u mber o f publica t ion s published recent ly has not y et reach ed t he l e vel of the 1980s. Based on a study of 15 t he three Bal t i c stat es, na m e ly Estonia, Latvia a nd Li t huania, Alli k (2013) sh owed t ha t diff erent countri e s w i t h t he same start i n g po si t ions co ul d devel o p o ver t he y ears o n com plete ly d iffe rent t raj ect o ri es – dependent o n poli c ies and decisi o ns m ade by t heir poli c y ma kers – to en d up wi t h diff erent scientific perf or manc es. Our resul t s a ls o suggest that a countr y ’s scient ifi c s ys t em a nd poli c y can affect publicat i o n pr oductivi t y . Su ffice to look at Russi a and Ukra ine, which d i d not devel o p m uch ove r t he la st 20 y e ars in t erms of publica t ion effici ency in j o ur nals indexed in WoS ev e n t hough authors from t he se two countr i es pu blish ed t he m o st papers in such j o urnals in t he 1980s.

A ccord in g to the UNESCO Sci e nce Report ( 2010), of t he EE countri es Bulgaria, Mol dova an d Montenegro were still su ff er ing fro m seri ous br ain drain .

Cl o se co -authorshi p re l at i o ns with Germ a ny co u l d be e xplaine d by i t s re la t ive pro xim i t y t o t he EE countri es (Bor nmann , Le y d esdo rff , Walch-So lim e na, & Ett l 2011) as well as t he earli er histo ry o f Ger many: East Germany ( GD R) was i t se lf under the USSR’s infl u e nce.

For m o st co un t r i e s the si t uat i o n was act ually t he o ppo si t e – coll abor ati on in creased. Russia is an example; i t s li g ht ly increased i t s sc ien t ific co ll a borat i o n wi t h Pol a nd, Hungar y , t he Cze ch Republi c a nd Sl ovakia, and Ro m a nia. O f cour se i t i s diffi cul t to com pare t he se pheno m e na in 1990 a nd in later y ears, s ince the Rus sian netwo rk of in t er nat i o nal co ll a borat i o n was d iff erent f r om that of t he USSR, especi ally w i t h t he in c lusi o n of Ukra in e, f o rmer ly a So vi et st ate. 16 Hun gar y a nd Romania are ex amples o f a d iff ere nt phen o m enon – t hei r co -authorshi p re l at i o ns wi t h t he other EE co un t ri es in creased o nly re cently (w hich can b e o bs er ved f o r 2011 as com par ed t o 1990 and 2000) . It suggests that t he po li t ical a nd soci eta l changes t he se countr i es u nde rwent have ha d a de layed effec t o n these co untri es’ scient ifi c systems. A ge ne ra l p icture o f interna t ional co ll a borat i on a mong research ers f ro m the EE countr i es is that it seems to have been boo s t ed rece n t ly , as can be seen by co mpar in g t he si t uat i on in 2000 a nd 2011.
