Validation and development of norms for the Test for Auditory Comprehension of Language‐Revised (TACL‐R) in Lebanon

Assessment of auditory comprehension is necessary for therapeutic clinical intervention as well as remedial and special education services. In this study, the Test for Auditory Comprehension of Language‐Revised (TACL‐R), developed by Elizabeth Carrow‐Woolfolk in 1985 Carrow‐Woolfolk, E. 1985. Test for Auditory Comprehension of Language‐Revised, Allen, TX: DLM Teaching Resources.  [Google Scholar], was translated and adapted for use in the Lebanese culture. The adapted test was administered to 350 Lebanese children aged 3:0–9:11 selected on the basis of grade and school type. Norms were reported for each age and grade level. Reliability analysis showed that the adapted test provides consistent, stable and precise estimates of auditory comprehension ability. The test's construct validity was examined using several indices. In addition, evidence for concurrent validity was provided by examining the relationship between scores on the adapted test and teachers' ratings of students' language abilities. Obtained results were compared with those on the TACL‐R and were discussed in terms of their practical implications. Recommendations for further research were proposed.

Constructing a professional development school: A model of one school‐university partnership

Abstract

A partnership between an elementary school and a university in the Midwest evolved into a professional development school. The authors describe this process, making analogies to the process of constructing a house. The steps are also related to Kagan's (1991) stages of organizational development. From laying the foundation of the partnership through adding the sill (the vision), constructing the frame (the goals and objectives), adding the sheathing (the formal structure), installing siding (the implementation), to maintaining through assessment, the parallels are explored and analyzed. Because the process relates to individuals as well as an institution, the authors also discuss ways in which the processes diverge.

The process is presented as a model that might be useful to others engaged in creating a professional development school or improving teacher education. A visual of the model is included.     

Phonemic—Morphemic dissociation in university students with dyslexia: an index of reading compensation?

A phonological deficit constitutes a primary cause of developmental dyslexia, which persists into adulthood and can explain some aspects of their reading impairment. Nevertheless, some dyslexic adults successfully manage to study at university level, although very little is currently known about how they achieve this. The present study investigated at both the individual and group levels, whether the development of another oral language skill, namely, morphological knowledge, can be preserved and dissociated from the development of phonological knowledge. Reading, phonological, and morphological abilities were measured in 20 dyslexic and 20 non-dyslexic university students. The results confirmed the persistence of deficits in phonological but not morphological abilities, thereby revealing a dissociation in the development of these two skills. Moreover, the magnitude of the dissociation correlated with reading level. The outcome supports the claim that university students with dyslexia may compensate for phonological weaknesses by drawing on morphological knowledge in reading.     

Adaptive control of bi-directionally coupled Lorenz systems with uncertainties

The bi-directionally coupled Lorenz systems are linked to the modeling of a coupled double loop thermosyphon system where the mass momentum and heat exchange are both considered. As the key parameters of the system, known as Rayleigh numbers, increase, the system of differential equations predicts typical flow dynamics in a thermosyphon from heat conduction to time-dependent chaos. In many applications including the thermosyphon systems, there are uncertainties associated with mathematical models such as unmodeled dynamics and parameter variations. Also, under the high heat environment for a thermosyphon, there exist external disturbances quantitatively linked to the Rayleigh numbers. All these sources constitute uncertainties to the dynamical system. Our objective is to design adaptive controllers to stabilize the chaotic flow in each thermosyphon loop with unknown system parameters and existence of uncertainties. The controllers consist of a proportional controller with an adaptive gain and a wavelet network that reconstructs the unknown functions representing the uncertainties. Explicit stability bounds and adaptive laws for the control parameters are obtained so that the coupled Lorenz systems are globally stabilized.     

Academic procrastination and motivation of adolescents in Turkey

This article presents a study of academic procrastination and associated motivation variables in 508 adolescents from a general secondary school in central Turkey. Girls reported higher levels of self‐efficacy for self‐regulation and predicted higher Turkish grades than boys, but there was no difference in levels of procrastination. Academic self‐efficacy was a stronger predictor of procrastination for girls than for boys, but for both groups self‐efficacy for self‐regulation was the strongest predictor of procrastination. Most participants (83%) reported spending one hour or more procrastinating per day, with writing tasks the most prone to procrastination for boys and girls. When procrastinating, Turkish adolescent boys were more likely to spend time with electronic media (watching TV, emailing, going on‐line, and, in particular, playing computer games), whereas girls were most likely to read books, magazines, and newspapers. The article concludes with implications for researchers, and also for parents and educators of adolescents.     

Association between moderately oxidized low-density lipoprotein and high-density lipoprotein particle subclass distribution in hemodialyzed and post-renal transplant patients

Disturbances in the metabolism of lipoprotein profiles and oxidative stress in hemodialyzed (HD) and post-renal transplant (Tx) patients are proatherogenic, but elevated concentrations of plasma high-density lipoprotein (HDL) reduce the risk of cardiovascular disease. We investigated the concentrations of lipid, lipoprotein, HDL particle, oxidized low-density lipoprotein (ox-LDL) and anti-ox-LDL, and paraoxonase-1 (PON-1) activity in HD (n=33) and Tx (n=71) patients who were non-smokers without active inflammatory disease, liver disease, diabetes, or malignancy. HD patients had moderate hypertriglyceridemia, normocholesterolemia, low HDL-C, apolipoprotein A-I (apoA-I) and HDL particle concentrations as well as PON-1 activity, and increased ox-LDL and anti-ox-LDL levels. Tx patients had hypertriglyceridemia, hypercholesterolemia, moderately decreased HDL-C and HDL particle concentrations and PON-1 activity, and moderately increased ox-LDL and anti-ox-LDL levels as compared to the reference, but ox-LDL and anti-ox-LDL levels and PON-1 activity were more disturbed in HD patients. However, in both patient groups, lipid and lipoprotein ratios (total cholesterol (TC)/HDL-C, LDL-C/HDL-C, triglyceride (TG)/HDL-C, HDL-C/non-HDL-C, apoA-I/apoB, HDL-C/apoA-I, TG/HDL) were atherogenic. The Spearman’s rank coefficient test showed that the concentration of ox-LDL correlated positively with HDL particle level (R=0.363, P=0.004), and negatively with TC (R=−0.306, P=0.012), LDL-C (R=−0.283, P=0.020), and non-HDL-C (R=−0.263, P=0.030) levels in Tx patients. Multiple stepwise forward regression analysis in Tx patients demonstrated that ox-LDL concentration, as an independent variable, was associated significantly positively with HDL particle level. The results indicated that ox-LDL and decreased PON-1 activity in Tx patients may give rise to more mildly-oxidized HDLs, which are less stable, easily undergo metabolic remodeling, generate a greater number of smaller pre-β-HDL particles, and thus accelerate reverse cholesterol transport, which may be beneficial for Tx patients. Further studies are necessary to confirm this.     

The impact of professional development training on teachers’ performance in Abu Dhabi Cycle Two and Three schools

This research study examined the impact of professional development on teachers’ performance in Abu Dhabi in the United Arab Emirates (UAE) Cycle Two and Three private schools. The study employed a mixed-method research design developed in two phases which considered professional development (PD) for teachers from the combined perspectives of Adult Learning Theory and Desimone’s PD features. The quantitative findings of the research suggest that teachers improved their lesson planning, teaching methods, teaching tools, classroom management, and cooperation after the PD. However, the qualitative findings suggest that teachers had many concerns regarding the current PD program; thus, two features are added to Desimone’s framework especially if it is to be used in a country like the UAE.
