BACKGROUND Publications related to scoliosis have increased enormously. A differentiation between publications of major and minor importance has become difficult even for experts. Scientometric data on developments and tendencies in scoliosis research has not been available to date. The aim of the current study was to evaluate the scientific efforts of scoliosis research both quantitatively and...

A new method to directly synthesize single-crystalline CeO2 nanoparticles has been developed. The advantages of the method are rapid synthesis, at normal atmosphere, 100% productive ratio and low cost, with a great potential for scale-up. X-ray diffraction (XRD) spectra showed unusual peak width versus particle size, compared with Scherrer equation predictions. Scanning electron microscopy (SEM...

We consider the optimal sequential irreversible investment policy of a value maximizing firm facing decreasing returns to scale and interest rate uncertainty. We characterize the optimal accumulation policy and its value for a broad class of interest rate models by focusing on the marginal investment decision and deriving the marginal value of capital. We also state a set of conditions under wh...

This study examines vocabulary growth in two dimensions, receptive and controlled productive, and the interrelationship between these dimensions. The study focuses on the 2000, 3000, 5000 and academic word list levels. Data were collected from 41 high school students in China. The participants completed a pre-test in the third week of the first semester, and a post-test ten weeks later. The fin...

AIMS AND OBJECTIVES To examine the literature related to a large-scale quality improvement initiative, the 'Productive Ward: Releasing Time to Care', providing a bibliometric profile that tracks the level of interest and scale of roll-out and adoption, discussing the implications for sustainability. BACKGROUND Productive Ward: Releasing Time to Care (aka Productive Ward) is probably one of th...

Dialogic approaches based on active student participation, open, respectful discussion, exploring and critiquing different perspectives are increasingly found to support learning. However, the specific productive forms of teacher-student interaction have rarely been studied systematically. A recent large-scale project explored relationship between dialogic learning outcomes for students aged 10...
