1. The Implementation of the Project-Based Learning Approach in the Algerian EFL Context: Curriculum Designers' Expectations and Teachers' Obstacles

Author

Baghoussi, Meriem and El Ouchdi, Ilhem Zoubida

Abstract

To help learners acquire and develop the necessary skills for the 21st century, Algeria has adopted the Competency-Based Approach (CBA) along with the Project-based Learning (PBL) approach within its educational system. Theoretically speaking, the goal behind such reform is to shift from a content-based to a process-based learning/teaching and thus to make learning more relevant and realistic for students. However, in practice, teachers find difficulties in putting into practice the two approaches. The aim of the present paper is to explore those obstacles that hinder the execution of the PBL approach in the third-year secondary education English classes and to identify to what extent English language teachers master and use PBL methodology in their classes. To reach the aim of the study, the following hypothesis is put forward: teachers lack both training and background knowledge on the approaches that help to implement PBL in classrooms. For the sake of collecting information about the issue tackled in this study, twenty EFL teachers from some secondary schools in Mostaganem city received a questionnaire. The research findings confirm the hypothesis mentioned above. They reveal that teachers neither master nor use the project-based instruction proficiently in their classrooms despite the guidance provided in the third-year pedagogical documents. Those hindrances are due to the lack of professional training and the insufficient theoretical knowledge on the diverse approaches, methods and strategies related to PBL.

4. Language acquisition among infants born in carceral institutions in Algeria

Author

Ilhem Zoubida El Ouchdi

Abstract

Every year, many children are born in prisons. It has, however, been established in previous studies that the environment where the child lives is a key element in the process of the child’s language acquisition. The present research work aims to discover the effects of the carceral institution on the process of the child’s language acquisition. To reach this goal, the present investigation takes place in two rehabilitation institutions in Algeria. It collects data through interviews with mothers and interview with psychologists. The data collected is analysed and the triangulation of results revealed that the prison environment affects the child’s language acquisition at the lexical level. Moreover, it deprives the child of different situations that would enable him to acquire language. This study recommends that the prison authorities should draw attention to the importance of the psycholinguistic aspect of this category of children by providing better conditions for better language development.

Abstract

Objectives This study sought to establish worldwide and regional diagnostic reference levels (DRLs) and achievable administered activities (AAAs) for single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). Background Reference levels serve as radiation dose benchmarks to compare individual laboratories against aggregated data, helping to identify sites in greatest need of dose reduction interventions. DRLs for SPECT MPI have previously been derived from national or regional registries. To date there have been no multiregional reports of DRLs for SPECT MPI from a single standardized dataset. Methods Data were submitted voluntarily to the INCAPS (International Atomic Energy Agency Nuclear Cardiology Protocols Study), a cross-sectional, multinational registry of MPI protocols. A total of 7,103 studies were included. DRLs and AAAs were calculated by protocol for each world region and for aggregated worldwide data. Results The aggregated worldwide DRLs for rest-stress or stress-rest studies employing technetium Tc 99m–labeled radiopharmaceuticals were 11.2 mCi (first dose) and 32.0 mCi (second dose) for 1-day protocols, and 23.0 mCi (first dose) and 24.0 mCi (second dose) for multiday protocols. Corresponding AAAs were 10.1 mCi (first dose) and 28.0 mCi (second dose) for 1-day protocols, and 17.8 mCi (first dose) and 18.7 mCi (second dose) for multiday protocols. For stress-only technetium Tc 99m studies, the worldwide DRL and AAA were 18.0 mCi and 12.5 mCi, respectively. Stress-first imaging was used in 26% to 92% of regional studies except in North America where it was used in just 7% of cases. Significant differences in DRLs and AAAs were observed between regions. Conclusions This study reports reference levels for SPECT MPI for each major world region from one of the largest international registries of clinical MPI studies. Regional DRLs may be useful in establishing or revising guidelines or simply comparing individual laboratory protocols to regional trends. Organizations should continue to focus on establishing standardized reporting methods to improve the validity and comparability of regional DRLs.

Abstract

Objectives This study sought to describe worldwide variations in the use of myocardial perfusion imaging hardware, software, and imaging protocols and their impact on radiation effective dose (ED). Background Concerns about long-term effects of ionizing radiation have prompted efforts to identify strategies for dose optimization in myocardial perfusion scintigraphy. Studies have increasingly shown opportunities for dose reduction using newer technologies and optimized protocols. Methods Data were submitted voluntarily to the INCAPS (International Atomic Energy Agency Nuclear Cardiology Protocols Study) registry, a multinational, cross-sectional study comprising 7,911 imaging studies from 308 labs in 65 countries. The study compared regional use of camera technologies, advanced post-processing software, and protocol characteristics and analyzed the influence of each factor on ED. Results Cadmium-zinc-telluride and positron emission tomography (PET) cameras were used in 10% (regional range 0% to 26%) and 6% (regional range 0% to 17%) of studies worldwide. Attenuation correction was used in 26% of cases (range 10% to 57%), and advanced post-processing software was used in 38% of cases (range 26% to 64%). Stress-first single-photon emission computed tomography (SPECT) imaging comprised nearly 20% of cases from all world regions, except North America, where it was used in just 7% of cases. Factors associated with lower ED and odds ratio for achieving radiation dose ≤9 mSv included use of cadmium-zinc-telluride, PET, advanced post-processing software, and stress- or rest-only imaging. Overall, 39% of all studies (97% PET and 35% SPECT) were ≤9 mSv, while just 6% of all studies (32% PET and 4% SPECT) achieved a dose ≤3 mSv. Conclusions Newer-technology cameras, advanced software, and stress-only protocols were associated with reduced ED, but worldwide adoption of these practices was generally low and varied significantly between regions. The implementation of dose-optimizing technologies and protocols offers an opportunity to reduce patient radiation exposure across all world regions.

Abstract

To help learners acquire and develop the necessary skills for the 21st century, Algeria has adopted the Competency-Based Approach (CBA) along with the Project-based Learning (PBL) approach within its educational system. Theoretically speaking, the goal behind such reform is to shift from a content-based to a process-based learning/teaching and thus to make learning more relevant and realistic for students. However, in practice, teachers find difficulties in putting into practice the two approaches. The aim of the present paper is to explore those obstacles that hinder the execution of the PBL approach in the third-year secondary education English classes and to identify to what extent English language teachers master and use PBL methodology in their classes. To reach the aim of the study, the following hypothesis is put forward: teachers lack both training and background knowledge on the approaches that help to implement PBL in classrooms. For the sake of collecting information about the issue tackled in this study, twenty EFL teachers from some secondary schools in Mostaganem city received a questionnaire. The research findings confirm the hypothesis mentioned above. They reveal that teachers neither master nor use the project-based instruction proficiently in their classrooms despite the guidance provided in the third-year pedagogical documents. Those hindrances are due to the lack of professional training and the insufficient theoretical knowledge on the diverse approaches, methods and strategies related to PBL

OBJECTIVE While nuclear myocardial perfusion imaging (MPI) offers many benefits to patients with known or suspected cardiovascular disease, concerns exist regarding radiation-associated health effects. Little is known regarding MPI practice in Africa. We sought to characterise radiation doses and the use of MPI best practices that could minimise radiation in African nuclear cardiology laboratories, and compare these to practice worldwide. METHODS Demographics and clinical characteristics were collected for a consecutive sample of 348 patients from 12 laboratories in six African countries over a one-week period from March to April 2013. Radiation effective dose (ED) was estimated for each patient. A quality index (QI) enumerating adherence to eight best practices, identified a priori by an IAEA expert panel, was calculated for each laboratory. We compared these metrics with those from 7 563 patients from 296 laboratories outside Africa. RESULTS Median (interquartile range) patient ED in Africa was similar to that of the rest of the world [9.1 (5.1-15.6) vs 10.3 mSv (6.8-12.6), p = 0.14], although a larger proportion of African patients received a low ED, ≤ 9 mSv targeted in societal recommendations (49.7 vs 38.2%, p < 0.001). Bestpractice adherence was higher among African laboratories (QI score: 6.3 ± 1.2 vs 5.4 ± 1.3, p = 0.013). However, median ED varied significantly among African laboratories (range: 2.0-16.3 mSv; p < 0.0001) and QI range was 4-8. CONCLUSION Patient radiation dose from MPI in Africa was similar to that in the rest of the world, and adherence to best practices was relatively high in African laboratories. Nevertheless there remain opportunities to further reduce radiation exposure to African patients from MPI.

Abstract

BACKGROUND This paper examines the current status of radiation exposure to patients in myocardial perfusion imaging (MPI) in Asia.Methods and Results:Laboratories voluntarily provided information on MPI performed over a 1-week period. Eight best practice criteria regarding MPI were predefined by an expert panel. Implementation of ≥6 best practices (quality index [QI] ≥6) was pre-specified as a desirable goal for keeping radiation exposure at a low level. Radiation effective dose (ED) in 1,469 patients and QI of 69 laboratories in Asia were compared against data from 239 laboratories in the rest of the world (RoW). Mean ED was significantly higher in Asia (11.4 vs. 9.6 mSv; P

Abstract

Background There is concern about radiation exposure with radionuclide myocardial perfusion imaging (MPI). This sub-study of the International Atomic Energy Agency (IAEA) Nuclear Cardiology Protocols Study reports radiation doses from MPI, and use of dose-optimisation protocols in Australia and New Zealand (ANZ), and compares them with data from the rest of the world. Methods Data were collected from 7911 MPI studies performed in 308 laboratories worldwide in one week in 2013, including 439 MPI studies from 34 ANZ laboratories. For each laboratory, effective radiation dose (ED) and a quality index (QI) score (out of 8) based on pre-specified "best practices'' was determined. Results In ANZ patients, ED ranged from 0.9-17.9 milliSievert (mSv). Median ED was similar in ANZ compared with the rest of the world (10.0 (IQR: 6.5-11.7) vs. 10.0 (IQR 6.4-12.6, P=0.15), as were mean QI scores (5.5 +/- 0.7 vs. 5.4 +/- 1.3, P= 0.84). Use of stress-only imaging (17.6% vs. 31.8% of labs, P= 0.09) and weight-based dosing of technetium-99m (14.7% vs. 30.3%, P= 0.07) was lower in ANZ compared with the rest of the world but this difference was not statistically significant. Median ED was significantly lower in metropolitan versus nonmetropolitan laboratories (10.1 mSv vs. 11.6 mSv, P < 0.01), although mean QI scores were similar (5.4 +/- 0.8 vs. 5.5 +/- 0.7, P= 0.75). Conclusion Across ANZ, there is variability in ED from MPI, and use of radiation safety practices, particularly between metropolitan and non-metropolitan laboratories. Overall, ANZ laboratories have a similar median ED to laboratories in the rest of the world.

Abstract

Purpose Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. Methods In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Results Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 +/- 3.4 mSv (RoW 11.4 +/- 4.3 mSv; P < 0.001) and of PET was 2.6 +/- 1.5 mSv (RoW 3.8 +/- 2.5 mSv; P < 0.001). The mean effective doses of SPECT and PET differed between European regions (P < 0.001 and P = 0.002, respectively). The mean quality score was 6.2 +/- 1.2, which was higher than the RoW score (5.0 +/- 1.1; P < 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. Conclusion In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in relation to the best practice quality score. A possible reason for the differences between Europe and the RoW could be the safety culture fostered by actions under the Euratom directives and the implementation of diagnostic reference levels. Stress-only imaging and weight-adjusted activity might be targets for optimization of European nuclear cardiology practice.

Abstract

Aims To characterize patient radiation doses from nuclear myocardial perfusion imaging (MPI) and the use of radiation-optimizing ‘best practices’ worldwide, and to evaluate the relationship between laboratory use of best practices and patient radiation dose. Methods and results We conducted an observational cross-sectional study of protocols used for all 7911 MPI studies performed in 308 nuclear cardiology laboratories in 65 countries for a single week in March–April 2013. Eight ‘best practices’ relating to radiation exposure were identified a priori by an expert committee, and a radiation-related quality index (QI) devised indicating the number of best practices used by a laboratory. Patient radiation effective dose (ED) ranged between 0.8 and 35.6 mSv (median 10.0 mSv). Average laboratory ED ranged from 2.2 to 24.4 mSv (median 10.4 mSv); only 91 (30%) laboratories achieved the median ED ≤ 9 mSv recommended by guidelines. Laboratory QIs ranged from 2 to 8 (median 5). Both ED and QI differed significantly between laboratories, countries, and world regions. The lowest median ED (8.0 mSv), in Europe, coincided with high best-practice adherence (mean laboratory QI 6.2). The highest doses (median 12.1 mSv) and low QI (4.9) occurred in Latin America. In hierarchical regression modelling, patients undergoing MPI at laboratories following more ‘best practices’ had lower EDs. Conclusion Marked worldwide variation exists in radiation safety practices pertaining to MPI, with targeted EDs currently achieved in a minority of laboratories. The significant relationship between best-practice implementation and lower doses indicates numerous opportunities to reduce radiation exposure from MPI globally.

Abstract

The progress of industry integrated circuits in recent years has been pushed by continuous miniaturization of transistors. With the reduction of dimensions of components at 0.1 micron and below, new physical effects come into play as the standard simulators of two dimensions (2D) do not consider. In fact the third dimension comes into play because the transverse and longitudinal dimensions of the components are of the same order of magnitude. To describe the operation of such components with greater fidelity, we must refine simulation tools and adapted to take into account these phenomena. After an analytical study of the static characteristics of the component, according to the different operating modes, a numerical simulation is performed of field-effect transistor with submicron gate MESFET GaInP. The influence of the dimensions of the gate length is studied. The results are used to determine the optimal geometric and physical parameters of the component for their specific applications and uses., {"references":["Kittel, Physique de l'etat solide, Ed.

Abstract

PURPOSE: Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. METHODS: In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). RESULTS: Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 ± 3.4 mSv (RoW 11.4 ± 4.3 mSv; P < 0.001) and of PET was 2.6 ± 1.5 mSv (RoW 3.8 ± 2.5 mSv; P < 0.001). The mean effective doses of SPECT and PET differed between European regions (P < 0.001 and P = 0.002, respectively). The mean quality score was 6.2 ± 1.2, which was higher than the RoW score (5.0 ± 1.1; P < 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. CONCLUSION: In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional

Abstract

Le développement qu’a connu le domaine de la micro-électronique est dû en grande partie aux évolutions techniques et en particulier à la miniaturisation des dispositifs semi-conducteurs, mais aussi à l’utilisation de nouveaux matériaux tel que les matériaux composés III-V pour les applications dans l’optoélectronique et l’électronique de puissance. Dans le but d’étudier les caractérisations du phénomène du transport électronique dans les matériaux composés ternaires et plus précisément dans le matériau GaxIn1-xSb, on a utilisé la simulation numérique basée sur les méthodes de Monte Carlo. Ce modèle consiste à simuler le comportement des électrons dans les semi-conducteurs qui se fait en deux étapes successives ; le libre parcours moyen et les collisions avec le réseau, et de tirer par la suite les fonctions de distribution des électrons de la bande de conduction qui sont similaires à ceux trouvés par la résolution de l’équation de Boltzmann. Pour cela, on a employé un modèle qui tient compte que de trois vallées isotropes et non paraboliques de la bande de conduction , L, et X. Les résultats obtenus sont satisfaisants après leurs comparaisons avec d’autres résultats expérimentaux existant dans la littérature. Ils nous renseignent sur la dynamique électronique ainsi que le comportement dans les hauts champs électriques et hautes températures de ce matériau.

Abstract

Ce travail de magister est divisé en deux volets : Le premier volet est une contribution à l’étude de matériaux mésoporeux présentant un potentiel principalement dans le domaine de la catalyse. Le premier objectif de ce volet est la préparation des supports mésoporeux via deux stratégies de synthèse : les matériaux mésoporeux SBA-15 (silice) et Al-SBA-15 (Si/Al =20 et 60) ont été synthétisés par la méthode « soft template » en utilisant un surfactant neutre un copolymère tribloc comme agent structurant tandis que le carbone mésoporeux CMK-3 a été synthétisé en utilisant la méthode « hard template » en utilisant comme agent structurant la silice mésoporeuse SBA-15. Le second objectif de ce premier volet concerne la synthèse de catalyseurs mésoporeux par modification postsynthétique des supports mésoporeux synthétisés. Les catalyseurs synthétisés sont de type Me-SBA-15 (Me : Ni, Cu, Co et Pd), Cu-Ni-SBA-15 à différentes teneurs et Cu-Ni-Support mésoporeux (Support : SBA-15, Al-SBA-15 (Si/Al = 20 et 60) et CMK-3). Les différentes techniques utilisées pour la caractérisation des catalyseurs mettent bien en évidence que les catalyseurs synthétisés sont mésoporeux et de structure hexagonale. Il faut cependant noter que la structure des catalyseurs obtenus est moins bien ordonnée que celle des supports correspondants ; ce résultat est du à la distorsion du réseau suite à l’incorporation des métaux. Le deuxième volet concerne l’application des catalyseurs préparés au vaporeformage des alcools (méthanol et éthanol). Les principaux résultats de cette partie ont montré que l’activité et la sélectivité en H2 de ces catalyseurs dépend de la nature du support, de la nature et la teneur de la phase active et de la température de la réaction. Les catalyseurs 2Cu-14Ni-SBA-15 et 2Cu-14Ni-CMK-3 se sont révélés des catalyseurs potentiels pour la production d’hydrogène par vaporeformage des alcools
