BACKGROUND Journal impact factor (IF) is linked to the probability of a paper being cited and is progressively becoming incorporated into researchers' curricula vitae. Furthermore, the decision as to which journal a given study should be submitted, may well be based on the trend in the journal's overall quality. This study sought to assess time trends in journal IF in the field of public, envir...

PURPOSE Studies undertaken in England and Scotland have identified a decrease in the number of circumcision operations being performed during childhood. The aims of this study were two-fold. Firstly, to determine the trend in circumcision operations performed in boys in Northern Ireland over a ten year period. Secondly, to compare the number of operations performed by paediatric surgeons with t...

This paper presents a statistical analysis of Tehran Price Index (TePIx) for the period of 1992 to 2004. The results present asymmetric property of the return distribution which tends to the right hand of the mean. Also the return distribution can be fitted by a stable Lévy distribution and the tails are very fatter than the gaussian distribution. We estimate the tail index of the TePIx returns...

Emergence and spread of drug resistant Neisseria gonorrhoeae is global concern. We evaluated trends of antimicrobial resistance in Neisseria gonorrhoeae over years 1992-2009 in Pakistan. Resistance rates were compared between years (2007-2009) and (1992-2006). Antimicrobial susceptibility testing was performed and interpreted according to Clinical Laboratory Standards Institute (CLSI) criteria ...

BACKGROUND Some patients with mild or moderate thoracic scoliosis (Cobb angle <50-60 degrees) suffer disproportionate impairment of pulmonary function associated with deformities in the sagittal plane and reduced flexibility of the spine and chest cage. Long-term improvement in the clinical signs and symptoms of childhood onset scoliosis in an adult, without surgical intervention, has not been ...

Abstract Population, salinity, and increasing water consumption have caused high pressure on groundwater resources in Iran. The study reported here investigates the change of quality Zrebar lake basin relationship between it with land-use precipitation rate from 1992 to 2018. To achieve intended goal, chemical parameters wells around lake, bicarbonate (HCO 3− ), sulfate (SO 4 sodium absorption ...

BACKGROUND Clotting factor products have been safe for HIV since 1985, and for hepatitis C since 1992. Few studies have reported on mortality in the total population of hemophilia patients after the period of risk of viral infection transmission. OBJECTIVES We studied the mortality, causes of death, and life expectancy of hemophilia patients between 1992 and 2001. We compared these findings w...

This paper estimates open-economy macroeconomic models of the Chinese economy allowing for structural change caused by 1992 reforms. Unrestricted vector autoregressions, VARs, and cointegrating error correction models, VECMs, are estimated on quarterly data early reform period 1980–1992, late period, 1993–2018. Two long-run vectors identified, which can be interpreted as a long-run, money deman...
