BACKGROUND Assessment of the potentially difficult airway (DA) is a critical aspect of resident education. We investigated the impact of a new assessment form on airway prediction and management by anaesthesia residents. We hypothesized that residents would demonstrate improvement in evaluation of DAs over the study duration. METHODS After IRB approval, anaesthesia residents were randomized i...

PURPOSE To assess the identification accuracy of dynamic assessment (DA) of narrative ability in English for children learning English as a 2nd language. METHOD A DA task was administered to 54 children: 18 Spanish-English-speaking children with language impairment (LI); 18 age-, sex-, IQ- and language experience-matched typical control children; and an additional 18 age- and language experie...

BACKGROUND Children's low scores on vocabulary tests are often erroneously interpreted as reflecting poor cognitive and/or language skills. It may be necessary to incorporate the measurement of word-learning ability in estimating children's lexical abilities. AIMS To explore the reliability and validity of the Dynamic Assessment of Word Learning (DAWL), a new dynamic assessment of receptive v...

The present study is an attempt to shed light on the effect of Dynamic Assessment (DA) on diagnosing and developing the receptive vocabulary abilities of upper-intermediate learners learning English as a foreign language. Fifty L2 leaners participated in the First Certificate in English test and completed Vocabulary Knowledge Scale. Out of 50 students, ten learners who were identified as being ...

Let G be a finite group, F a free group of finite rank, R the kernel of a homomorphism tp of F onto G, and let [ i i , f] , [R,R] denote mutual commutator subgroups. Conjugation in F yields a G-module structure on R/[R,R]; let da[R/[R, R]) be the number of elements required to generate this module. Define d(R/[R, F]) similarly. By an earlier result of the first author, for a fixed G, the differ...

We studied the effects of ethanol on concentrations of noradrenaline (NE), dopamine (DA) and serotonin (5-HT) and their metabolites in rat hippocampus and striatum. Ethanol (2 or 4 g/kg, po, from a 20% aqueous solution) was administered daily to male Wistar rats (4-13 per group) for 30 days and animals were sacrificed 30 min or 48 h after the last administration. Monoamines were measured by HPL...

The main result in this note is that if X is a simple loop in the boundary of a compact, irreducible, orientable 3-manifold M and [X] ¥= 1 G trx(M), one can represent the centralizer of [X] in irx(M) by a Seifert fibred submanifold of M. Introduction. The main result in this note is a partial answer to a question of Jaco [2]. Jaco has shown in [2] that the centralizer of a nontrivial element in...

Dynamic assessment (DA) has been advocated as an interactive approach to conduct assessments to students in the learning systems as it can differentiate student proficiency at a finer grained level. Sternberg and others have been pursuing an alternative to IQ tests. They proposed to give students tests to see how much assistance it takes a student to learn a topic; and to use as a measure of th...

BACKGROUND WSG-ARA plus trial evaluated the effect of adjuvant darbepoetin alfa (DA) on outcome in node positive primary breast cancer (BC). PATIENTS AND METHODS One thousand two hundred thirty-four patients were randomized to chemotherapy either with DA (DA+; n = 615) or without DA (DA-; n = 619). DA (500 µg q3w) was started at hemoglobin (Hb) levels <13.0 g/dl (<12 g/dl after DA label amend...
