Under conventional inflation targeting (IT), the lower bound on nominal interest rates gives rise to a systematic downward bias in that substantially reduces welfare. Using two variants of New Keynesian model, we investigate whether monetary policy strategy aims stabilize an average rate—rather than period-by-period rate—leads better outcomes. With rational expectations, price level (PLT)—the l...

The average convergence rate (ACR) measures how fast the approximation error of an evolutionary algorithm converges to zero per generation. It is defined as geometric reduction over consecutive generations. This paper makes a theoretical analysis ACR in continuous optimization. obtained results are summarized follows. According limit property, classified into two categories: (1) linear whose in...

background and objectives: hospital is the largest and most costly operating unit of healthcare system. provision of optimal care requires that hospital administrators identify hospital performance based on relevant indicators. this study used the pabon lasso analysis to assess the performance of hospitals and identify strategies towards an improved hospital performance.   methods: this cross-s...

Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...

A pedigree file consisting of 5860 individuals, 167 sires and 1582 dams collected at Makooei sheep breeding station (MSBS) during a period of 24 years (1990 to 2013) was used to calculate the inbreeding coefficients to reveal any probable effects of inbreeding (F) on the studied traits. The studied traits were classified to the five main groups including body weight, Kleiber ratio, body measure...

studbook information collected from 1988 to 2011 in jafarabad breeding station of moghani sheep, north-west of iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. lambs born during 2009-2011 were considered as reference population. means inbreeding and average coancestry for t...
