Abstract

Citation analysis, in addition to peer review, is one of the popular methods to assess faculty research performance. In some disciplines, the validity of citation counts for evaluating research has been proven by many studies. However, it should be used cautiously when different disciplines are concerned, because citation practices may vary across disciplines. Although there have been studies that have examined the different citation practices across disciplines, relatively little research has investigated the citation rates of subject areas within a single discipline. This study explores the citation rates of subject areas in library and information science (LIS) in Korea. The preliminary results of this study will provide the rationale for further work, analyzing the causes of different citation patterns in a discipline. Ultimately, the study could provide useful implications for understanding and using the citation counts in assessing research performance. [ABSTRACT FROM AUTHOR]

Abstract

The prevalence of aac(6')-Ib-cr and its associated genes and mobile elements was investigated in Serratia marcescens collected from 12 hospitals in Korea in 2005 and 2006. A total of 215 isolates (from 166 and 149 isolates collected in 2005 and 2006, respectively) were included in the study. Aac(6')-Ib-cr was detected in only two isolates collected in 2005 and in 12 isolates collected from three hospitals in 2006. All 12 isolates carried class 1 integron and coharbored bla(CTX-M) and armA. Bla(OXA-1) and ISCR1 were detected in 10 and 8 isolates, respectively. All 12 isolates carried IncL/M type plasmid and 6 of them also carried IncA/C type plasmid. Conjugal transfer was successful for 9 of 12 aac(6')-Ib-cr, all 12 bla(CTX-M), 8 of 12 armA, and 6 of 10 bla(OXA-1). Of the 12 transconjugants, IncL/M type plasmid, IntI1, ISEcp1, and ISCR1 were detected in 12, 9, 12, and 8, respectively. The transferability of aac(6')-Ib-cr, armA, and bla(OXA-1) was 100% for isolates harboring ISCR1, against 25%, 0%, and 0%, respectively, for isolates not harboring ISCR1. Both clonal and horizontal transfer were demonstrated by pulsed-field gel electrophoresis and plasmid profile analysis, respectively. Stringent infection control practices and further investigation of association between mobile elements and resistance genes are warranted.
