In light of the fact that L2 pronunciation errors are often caused by the transfer of well-established L1 sound systems, this paper examines some of the outstanding phonological differences between Persian and English. Comparing segmental and supra-segmental aspects of both languages, this study also discusses several problematic areas of pronunciation facing Iranian learners of English. To rea...

Postoperative delirium (POD) is a common neuropsychiatric disorder characterized by inattention, fluctuating levels of consciousness, and disorganized thinking. POD can have serious consequences, including institutionalization and death. Risk stratification may target prevention to individuals at greater risk of POD. The objective of this study was to identify all published POD risk prediction ...

Haploidization of the genome in meiosis requires that chromosomes be sorted exclusively into pairs stabilized by synaptonemal complexes (SCs) and crossovers. This sorting and pairing is accompanied by active chromosome positioning in meiotic prophase in which telomeres cluster near the spindle pole to form the bouquet before dispersing around the nuclear envelope. We now describe telomere-led r...

The paper reports on an investigation of attention and working memory as sources of intelligence. The investigation was concentrated on the relatedness of attention and working memory as predictors of intelligence and on the structure underlying the prediction. In a sample of 120 participants, intelligence was assessed by the Advanced Progressive Matrices [APM; Raven, J. C. (1962). Advanced pro...

Although investigators have established that compulsive polydrug abuse adversely affects intellectual efficiency, the effects of prolonged heroin use remain unclear. The issue was assessed by comparing levels of intellectual functioning, as measured by the Raven Progressive Matrices, with expected levels of visual memory, as measured by the Benton Revised Visual Retention Test (BVRT). Whereas s...

Three inspection-time tasks measuring the amount of time required to discriminate differences in pitch, loudness and phase were administered alongside the Multidimensional Ability Battery and Raven s Advanced Progressive Matrices to 75 undergraduate students. The auditory tasks were administered adaptively, and thresholds were estimated by fitting a logistic function to each set of data. After ...

bal cognitive abilities, birth weight, and minimal brain injury. A total of 45 (20 MZ and 25 DZ) twins pairs of both sexes were matched with 90 singletons of the same age, sex, and schooclass. All subjects were Israeli kibbutzl born youngsters, and as such were all of the same social background.
