Published: November 2023

We present the results of a temperature-dependent photoluminescence (PL) spectroscopy study on CuInS2 quantum dots (QDs). In order to elucidate the influence of QD size on PL temperature dependence, size-selective precipitation was used to obtain several nanoparticle fractions. Additionally, the nanoparticles’ morphology and chemical composition were studied using transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The obtained QDs showed luminescence in the visible–near infrared range. The PL energy, linewidth, and intensity were studied within an 11–300 K interval. For all fractions, a temperature decrease led to a shift in the emission maximum to higher energies and pronounced growth of the PL intensity down to 75–100 K. It was found that for large particle fractions, the PL intensity started to decrease, with temperature decreasing below 75 K, while the PL intensity of small nanoparticles remained stable.

Published: November 2023

Eating disorders (EDs) and disordered eating behaviours (DEBs) are significant health problems related to body image and weight dissatisfaction among adolescents and young adults worldwide. During this stage of sensitive development, these behaviours may hinder the optimal growth process and can consequently lead to wasting, stunting, and micronutrient deficiencies. However, there is a limited amount of literature on DEB among Arab populations, particularly in Saudi Arabia. This review aims to assess the prevalence of EDs/DEB and to develop a clear understanding of the epidemiology of such conditions among adolescents and youth in Saudi Arabia. Five databases were systematically searched and 14 papers met the inclusion criteria. The Eating Attitudes Test (EAT-26) was the predominant tool used for evaluating aberrant eating behaviours, indicating a high prevalence of EDs/DEB ranging from 10.2% to 48.1%. The highest prevalence of EDs/DEB was reported in the eastern region ranging from 29.4% to 65.5%. In terms of age and sex, the prevalence was higher among older students compared to younger school students and males reported more Eds/DEB compared to female students. These disorders are found to be prevalent in Saudi Arabia, and the risk of developing such conditions is high across the whole age range.

Published: November 2023

Albertia edulis is known as Puruí, and its leaf tea is used in the hypoglycemic and antihypertensive treatments of the Amazon native population. This study aimed to evaluate the phytochemical composition and antioxidant properties of the Puruí pulp fruit. The hydroethanolic (LFP-E), ethyl acetate (LFP-A), and volatile concentrate (LPF-V) extracts of Puruí lyophilized fruit pulp were analyzed via LC-ISI-IT-MS, GC, and GC-MS. Moreover, total phenolic and flavonoid content (TPC and TFC) and TEAC/ABTS and DPPH assays were conducted to determine their antioxidant capacity. Compounds palmitic acid, methyl linolenate, methyl linoleate, palmitic alcohol, benzene acetaldehyde, tridecanal, and furfural were mainly identified in the LPF-V extract. Compounds caffeic and quinic acids, genipin, annonaine, 3′-7-dimethoxy-3-hydroxyflavone, 4′-hydroxy-5,7-dimethoxyflavone, 6-hydroxy-7-epigardoside methyl ester, baicalin, and phloretin-2-O-apiofuranosyl-glucopyranoside were mainly identified in the LFP-E and LFP-A extracts. For LFP-E and LFP-A extracts, TPC values were 5.75 ± 0.75 and 66.75 ± 3.1 mg GAE/g; TFC values were 1.14 ± 0.65 and 50.97 ± 1.2 mg QE/g; DPPH assay showed EC50 values of 1021.65 ± 5.9 and 133.60 ± 3.9 µg/mL; and TEAC/ABTS assay showed values of 28.36 ± 3.7 and 142.26 ± 2.2 µM TE/g. Alibertia edulis fruits are significant sources of phenolic compounds, also showing significant antioxidant capacity. The Puruí fruit seems promising for developing innovative and healthy products for the nutritional food market.
Microemulsions: An Encapsulation Strategy to Increase the Thermal Stability of D-limonene
Authors: Belem Bruna Rodrigues , Carapeto Gustavo Vaiano , Issa Michele Georges , Ferraz Humberto Gomes
Published: November 2023

D-limonene, derived from citrus essential oils, holds significant therapeutic potential but faces challenges due to its high volatility, especially in pharmaceutical formulations. This study investigates microemulsions as a promising delivery system for volatile compounds, emphasizing their thermal protection for D-limonene. The formulation development was guided by a pseudo-ternary phase diagram and involved assays with different surfactants. Microemulsions were achieved solely with Labrasol® (Gattefossé Brasil, São Paulo, Brazil), encompassing concentrations of 7.1% to 30.8% D-limonene, 28.6% to 57.1% Labrasol®, and 20.0% to 64.3% water. All formulations were homogeneous, transparent, and presented low viscosity, with adequate D-limonene content, indicating that the production is feasible at room temperature. While the formulations demonstrated robust physical stability under mechanical stress, they exhibited destabilization at temperatures exceeding 50 °C. In terms of oxidative stability, pure D-limonene exhibited an induction period of 4.88 min, whereas microemulsions extended this period by four to eight times. Notably, the induction period of the microemulsions remained practically unchanged pre and post-heating (70 °C), suggesting the formulation’s ability to enhance the D-limonene thermal stability. This highlights the value of oxidative stability analysis as a quicker tool than conventional oxidative tests, while affirming microemulsions as a viable encapsulation strategy for D-limonene protection against elevated temperatures.

Midazolam (MDZ) is used for sedation in surgical procedures; its clinical effect is related to its receptor affinity and the dose administered. Therefore, a pharmacokinetic–pharmacodynamic (PK-PD) population model of MDZ in pediatric patients undergoing minor surgery is proposed. A descriptive, observational, prospective, and longitudinal, study that included patients of both sexes, aged 2–17 years, ASA I/II, who received MDZ in IV doses (0.05 mg/kg) before surgery. Three blood samples were randomly taken between 5–120 min; both sedation by the Bispectral Index Scale (BIS) and its adverse effects were recorded. The PK-PD relationship was determined using a nonlinear mixed-effects, bicompartmental first-order elimination model using Monolix Suite™. Concentrations and the BIS were fitted to the sigmoid Emax PK-PD population and sigmoid Emax PK/PD indirect binding models, obtaining drug concentrations at the effect site (biophase). The relationship of concentrations and BIS showed a clockwise hysteresis loop, probably indicating time-dependent protein binding. Of note, at half the dose used in pediatric patients, adequate sedation without adverse effects was demonstrated. Further PK-PD studies are needed to optimize dosing schedules and avoid overdosing or possible adverse effects.

Published: November 2023

Etoricoxib is a non-steroidal anti-inflammatory drug with high selectivity for cyclooxygenase 2 (COX-2), exerting a pronounced anti-inflammatory effect with fewer adverse events when compared to COX-1 inhibitors. The present study aimed to evaluate the bioequivalence between two etoricoxib-coated tablet formulations to meet regulatory requirements for a branded generic product registration in Brazil. A crossover study with an open-label, randomized design and a single-dose regimen with two treatments and two periods was conducted on healthy Brazilians of both genders. Subjects randomly received a single dose of a 90 mg etoricoxib coated tablet of test product Xumer® 90 mg (Adium S.A.) and the reference product Arcoxia® 90 mg (Merck Sharp & Dohme Farmacêutica Ltda.) under fasting conditions separated by a 14-day period. Blood samples were collected sequentially for up to 96 h following drug administration, and the concentrations of etoricoxib in plasma were determined using a validated UPLC-MS/MS method. Pharmacokinetic parameters were computed utilizing non-compartmental analysis methods. A total of 32 healthy subjects were enrolled, and 25 subjects completed the study. Geometric mean ratios (90% confidence intervals) for Cmax, AUC0-t, and AUC0-inf were 103.98% (95.63–113.06), 96.82% (91.82–102.09), and 95.79% (90.70–101.16), respectively. In accordance with regulatory standards, the test formulation (Xumer® 90 mg) has been deemed bioequivalent to the reference product (Arcoxia® 90 mg). As a result, these formulations can be considered interchangeable in clinical practice, with both proving to be safe and well-tolerated. The need for in vivo testing for the Xumer® 60 mg strength was waived due to the proportional similarity of the formulations and the similar in vitro dissolution profiles observed across the various strengths.

Published: November 2023

The stability and release properties of all bioactive capsules are strongly related to the composition of the wall material. This study aimed to evaluate the effect of the wall materials during the encapsulation process by ionotropic gelation on the viability of Lactobacillus fermentum K73, a lactic acid bacterium that has hypocholesterolemia probiotic potential. A response surface methodology experimental design was performed to improve bacterial survival during the synthesis process and under simulated gastrointestinal conditions by tuning the wall material composition (gelatin 25% w/v, sweet whey 8% v/v, and sodium alginate 1.5% w/v). An optimal mixture formulation determined that the optimal mixture must contain a volume ratio of 0.39/0.61 v/v sweet whey and sodium alginate, respectively, without gelatin, with a final bacterial concentration of 9.20 log10 CFU/mL. The mean particle diameter was 1.6 ± 0.2 mm, and the experimental encapsulation yield was 95 ± 3%. The INFOGEST model was used to evaluate the survival of probiotic beads in gastrointestinal tract conditions. Upon exposure to in the vitro conditions of oral, gastric, and intestinal phases, the encapsulated cells of L. fermentum decreased only by 0.32, 0.48, and 1.53 log10 CFU/mL, respectively, by employing the optimized formulation, thereby improving the survival of probiotic bacteria during both the encapsulation process and under gastrointestinal conditions compared to free cells. Beads were characterized using SEM and ATR-FTIR techniques.
A Novel Adaptive Edge Aggregation and Multiscale Feature Interaction Detector for Object Detection in Remote Sensing Images
Authors: Huang Wei , Zhao Yuhao , Sun Le , Gao Lu , Chen Yuwen
Published: November 2023

Object detection (OD) in remote sensing (RS) images is an important task in the field of computer vision. OD techniques have achieved impressive advances in recent years. However, complex background interference, large-scale variations, and dense instances pose significant challenges for OD. These challenges may lead to misalignment between features extracted by OD models and the features of real objects. To address these challenges, we explore a novel single-stage detection framework for the adaptive fusion of multiscale features and propose a novel adaptive edge aggregation and multiscale feature interaction detector (AEAMFI-Det) for OD in RS images. AEAMFI-Det consists of an adaptive edge aggregation (AEA) module, a feature enhancement module (FEM) embedded in a context-aware cross-attention feature pyramid network (2CA-FPN), and a pyramid squeeze attention (PSA) module. The AEA module employs an edge enhancement mechanism to guide the network to learn spatial multiscale nonlocal dependencies and solve the problem of feature misalignment between the network’s focus and the real object. The 2CA-FPN employs level-by-level feature fusion to enhance multiscale feature interactions and effectively mitigate the misalignment between the scales of the extracted features and the scales of real objects. The FEM is designed to capture the local and nonlocal contexts as auxiliary information to enhance the feature representation of information interaction between multiscale features in a cross-attention manner. We introduce the PSA module to establish long-term dependencies between multiscale spaces and channels for better interdependency refinement. Experimental results obtained using the NWPU VHR-10 and DIOR datasets demonstrate the superior performance of AEAMFI-Det in object classification and localization.

Published: November 2023

Drifting icebergs present significant navigational and operational risks in remote offshore regions, particularly along the East Coast of Canada. In such areas with harsh weather conditions, traditional methods of monitoring and assessing iceberg-related hazards, such as aerial reconnaissance and shore-based support, are often unfeasible. As a result, satellite-based monitoring using Synthetic Aperture Radar (SAR) imagery emerges as a practical solution for timely and remote iceberg classifications. We utilize the C-CORE/Statoil dataset, a labeled dataset containing both ship and iceberg instances. This dataset is derived from dual-polarized Sentinel-1. Our methodology combines state-of-the-art deep learning techniques with comprehensive feature selection. These features are coupled with machine learning algorithms (neural network, LightGBM, and CatBoost) to achieve accurate and efficient classification results. By utilizing quantitative features, we capture subtle patterns that enhance the model’s discriminative capabilities. Through extensive experiments on the provided dataset, our approach achieves a remarkable accuracy of 95.4% and a log loss of 0.11 in distinguishing icebergs from ships in SAR images. The introduction of additional ship images from another dataset can further enhance both accuracy and log loss results to 96.1% and 0.09, respectively.
Seasonal Variations in Ion Density, Ion Temperature, and Migrating Tides in the Topside Ionosphere Revealed by ICON/IVM

Published: November 2023

Based on the plasma parameters measured by the Ion Velocity Meter (IVM) instrument on the Ionospheric Connection Explorer (ICON) satellite from 2020 to 2021, we present an analysis of seasonal variations in ion density, ion temperature, and migrating tides in the low-latitude topside ionosphere. The interannual variations in total ion density and O+ density are directly impacted by solar radiation. However, the concentration of H+ is not highly related to solar activity. The measurements show that the hemispheric dividing latitude for the seasonal variation in Ti is at about 9°N. We suggest that the reason for the hemispheric dividing latitude being 9°N is because measurements at this geographical latitude represent the closest match to the geomagnetic equator. An anticorrelation in the seasonal variations between the total ion density (as well as the O+ density) and the ion temperature is observed at all observed latitudes while the correlations between H+ density and the ion temperature are positive in most of the latitudes except for serval degrees around 9°N. The latitudinal variations in the correlation coefficients lead us to suggest that thermal conduction is likely more important than ion-neutral collision in the ion energy budget at 600 km. Additionally, semiannual oscillations with peak amplitudes in winters and summers at the extra-equatorial latitudes are revealed in the observations of diurnal migrating tides in the topside ionosphere, which are different from the latitudinal and seasonal distributions of diurnal migrating tides captured in the lower thermospheric temperature and total electron content.
Hydrogen-Powered Aircraft at Airports: A Review of the Infrastructure Requirements and Planning Challenges
Authors: Gu Yue , Wiedemann Mirjam , Ryley Tim , Johnson Mary E. , Evans Michael John
Published: November 2023

Hydrogen-fueled aircraft are a promising innovation for a sustainable future in aviation. While hydrogen aircraft design has been widely studied, research on airport requirements for new infrastructure associated with hydrogen-fueled aircraft and its integration with existing facilities is scarce. This study analyzes the current body of knowledge and identifies the planning challenges which need to be overcome to enable the operation of hydrogen flights at airports. An investigation of the preparation of seven major international airports for hydrogen-powered flights finds that, although there is commitment, airports are not currently prepared for hydrogen-based flights. Major adjustments are required across airport sites, covering land use plans, airside development, utility infrastructure development, and safety, security, and training. Developments are also required across the wider aviation industry, including equipment updates, such as for refueling and ground support, and supportive policy and regulations for hydrogen-powered aircraft. The next 5–10 years is identified from the review as a critical time period for airports, given that the first commercial hydrogen-powered flight is likely to depart in 2026 and that the next generation of short-range hydrogen-powered aircraft is predicted to enter service between 2030 and 2035.

Authors: Gong Jun , Zhang Juling , Guo Wenqiang , Ma Zhilong , Lv Xiaoyi
Published: November 2023

Considering the poor effect of short text classification due to insufficient semantic information mining in the current short text matching methods, a new short text classification method is proposed based on explicit and implicit multiscale weighting semantic information interaction. First, the explicit and implicit representations of short text are obtained by a word vector model (word2vec), convolutional neural networks (CNNs), and long short-term memory (LSTM). Then, a multiscale convolutional neural network obtains the explicit and implicit multiscale weighting semantics information of short text. Finally, the multiscale weighting semantics is fused for more accurate short text classification. The experimental results show that this method is superior to the existing classical short text classification algorithms and two advanced short text classification models on the five short text classification datasets of MR, Subj, TREC, SST1 and SST2 with accuracies of 85.7%, 96.9%, 98.1%, 53.4% and 91.8%, respectively.
Novel Computations of the Time-Fractional Coupled Korteweg–de Vries Equations via Non-Singular Kernel Operators in Terms of the Natural Transform
Authors: Alzahrani Abdulrahman B. M. , Alhawael Ghadah
Published: November 2023

In the present research, we establish an effective method for determining the time-fractional coupled Korteweg–de Vries (KdV) equation’s approximate solution employing the fractional derivatives of Caputo–Fabrizio and Atangana–Baleanu. KdV models are crucial because they can accurately represent a variety of physical problems, including thin-film flows and waves on shallow water surfaces. Some theoretical physical features of quantum mechanics are also explained by the KdV model. Many investigations have been conducted on this precisely solvable model. Numerous academics have proposed new applications for the generation of acoustic waves in plasma from ions and crystal lattices. Adomian decomposition and natural transform decomposition techniques are combined in the natural decomposition method (NDM). We first apply the natural transform to examine the fractional order and obtain a recurrence relation. Second, we use the Adomian decomposition approach to the recurrence relation, and then, using successive iterations and the initial conditions, we can establish the series solution. We note that the proposed fractional model is highly accurate and valid when using this technique. The numerical outcomes demonstrate that only a small number of terms are required to arrive at an approximation that is exact, efficient, and trustworthy. Two examples are given to illustrate how the technique performs. Tables and 3D graphs display the best current numerical and analytical results. The suggested method provides a series form solution, which makes it quite easy to understand the behavior of the fractional models.
Endogenous Viral Elements in Ixodid Tick Genomes
Authors: Barnes Miranda , Price Dana C.
Published: November 2023

The documentation of endogenous viral elements (EVEs; virus-derived genetic material integrated into the genome of a nonviral host) has offered insights into how arthropods respond to viral infection via RNA interference pathways. Small non-coding RNAs derived from EVE loci serve to direct RNAi pathways in limiting replication and infection from cognate viruses, thus benefiting the host’s fitness and, potentially, vectorial capacity. Here we use informatic approaches to analyze nine available genome sequences of hard ticks (Acari: Ixodidae; Rhipicephalus sanguineus, R. microplus, R. annulatus, Ixodes ricinus, I. persulcatus, I. scapularis, Hyalomma asiaticum, Haemaphysalis longicornis, and Dermacentor silvarum) to identify endogenous viral elements and to illustrate the shared ancestry of all elements identified. Our results highlight a broad diversity of viral taxa as having given rise to 1234 identified EVEs in ticks, with Mononegavirales (specifically Rhabdoviridae) well-represented in this subset of hard ticks. Further investigation revealed extensive adintovirus integrations in several Ixodes species, the prevalence of Bunyavirales EVEs (notably not observed in mosquitoes), and the presence of several elements similar to known emerging human and veterinary pathogens. These results will inform subsequent work on current and past associations with tick species with regard to the viruses from which their “viral fossils” are derived and may serve as a reference for quality control of various tick-omics data that may suffer from misidentification of EVEs as viral genetic material.

Published: November 2023

For rapid and reliable detection of porcine epidemic diarrhea virus (PEDV) from pig clinical samples, a multiplex, real-time, reverse transcription loop-mediated isothermal amplification (mqRT-LAMP) was developed using two sets of primers and assimilating probes specific to the PEDV N gene and the Sus scrofa β-actin gene, which was used as an endogenous internal positive control (EIPC) to avoid false-negative results. The assay specifically amplified both target genes of PEDV and EIPC in a single reaction without any interference but did not amplify other porcine viral nucleic acids. The limit of detection was 10 copies/μL, 100-fold lower than that of a reverse transcription-polymerase chain reaction (RT-PCR) and equivalent to that of quantitative/real-time RT-PCR (qRT-PCR). This assay has high repeatability and reproducibility with coefficients of variation < 4.0%. The positive signal of the mqRT-LAMP assay was generated within 25 min, demonstrating advantages in rapid detection of PEDV over RT-PCR or qRT-PCR assay, which require at least 2 h turnaround times. In clinical evaluation, the detection rate of PEDV by mqRT-LAMP assay (77.3%) was higher than that of RT-PCR assay (69.7%), and comparable to qRT-PCR (76.8%) with almost 100% concordance (kappa value 0.98). The developed mqRT-LAMP assay can serve as an advanced alternative method for PEDV diagnosis because it has high sensitivity and specificity, rapidity, and reliability even in resource-limited laboratories.

Published: November 2023

The microbiological contamination of wild boar meat depends on the hygiene practices that hunters apply during its preparation, from the point of collection to its refrigeration. This study assesses Portuguese hunters’ knowledge of hygiene practices when handling wild boar carcasses that can jeopardise meat safety. A general structured survey entitled “Private consumption of game meat and good hygiene practices” was distributed to Portuguese hunters. Of the 206 respondents, 95% use wild boar meat for private consumption without prior inspection or initial examination by a veterinarian. This study also revealed that the vast majority of respondents have several risky practices that can compromise the safety of wild boar meat consumed (evisceration, handling, refrigeration, and transport). It is also evident that there is a lack of knowledge related to recognising lesions compatible with zoonotic infections in the hunted animals. These inappropriate knowledge and practices can pose a risk to hunters (occupational zoonotic health) and consumers (foodborne diseases). To reduce this risk, hunters need to be trained and informed about proper game meat handling practices.

An assessment of the quality of control of the parameters of the crankshaft of the ZMZ engine at the repair company was carried out. The metrological support system of the enterprise must guarantee the accuracy and quality of the repair of the crankshaft of the ZMZ engine, excluding the possibility of marriage during subsequent assembly. When the engines are repaired, the crankshafts are defective, after which they are replaced with new ones or processed for repair size. After processing the crankshaft for the repair size, it is necessary to carry out control according to six parameters. It was revealed that in order to measure the diameters of the main and connecting rod necks of the crankshaft, as well as their ovality, it is necessary to replace the micrometer 75-0.01 used at the enterprise, the maximum measurement error of which is twice as large as the permissible one, with a lever bracket 75- 0.002, in order to reduce the measurement error and improve the quality of control. To control the greatest beating of the second, third and fourth root necks relative to the first and fifth root necks, the hour-type indicator used at enterprises fully satisfies the specified conditions, the maximum error does not exceed the permissible one. To control the axial clearance of the already assembled crankshaft along the thrust bearing, 10-0.01 is also used, which provides the specified measurement accuracy with a three-fold margin. When measuring the length of the third root neck, the use of a caliper 125-0.05 leads to an excess of the permissible measurement error by 3 times, but there are no other more accurate universal measuring instruments for monitoring this parameter, because control is carried out by special sponges for measuring holes that are available only for calipers. It is recommended to design a gauge for the purpose of measuring the length of the third root neck.

Published: November 2023

The article presents the experience of a law firm in drawing up and implementing corporate Instructions for employees. The manager used SMART, Agile and SCRUM business technologies in his work. For four years, the Employee Violation Log was used to record findings. When their number began to directly impede business development, the manager analyzed the violations and noticed certain patterns. Regardless of qualifications and work experience, employees make the same mistakes, which are of an “everyday” nature. It has been established that employees do not know how to act in situations of uncertainty. Taking the most repeated mistakes as a basis, the manager created “Instruction No. 0” — a set of rules that describe the way out of possible controversial situations. It is noted that employees take a more responsible approach to completing tasks, and the manager began to devote more time to strategic business development. These rules have become the company's corporate culture.

Dans la banlieue parisienne, le Centre International de Massy
Authors: Charlot Martine
Published: November 2023

La C.I.M.A.D.E. anime à Massy — 11 km au sud de Paris — un Centre international de réfugiés et d’étudiants.

Sans revenir sur l’histoire du Centre qui remonte à une vingtaine d’années, précisons qu’il accueille aujourd’hui, en permanence, une centaine de résidents de trois catégories différentes :

— des réfugiés politiques pris en charge par l’aide publique (environ 45) ;

— des candidats au refuge attendant la régularisation de leur situation (pris en charge sur le budget propre de la C.I.M.A.D.E.) ;

— des étudiants français et étrangers (par convention avec le C.R.O.U.S.).

Les résidents appartiennent à environ 25 pays différents d’Afrique, d’Amérique latine, d’Europe, parfois d’Asie s’il s’agit d’étudiants. Les réfugiés pris en charge par l’aide publique restent environ 6 mois au foyer. La Direction départementale de l’Aide sanitaire et sociale (ministère de la Santé) assure les frais de cette prise en charge qui s’élevait, au printemps 1980, à 81,50 F par personne et par jour, et à 267 F d’argent de poche alloué au réfugié par quinzaine. Le Centre accueille surtout des isolés, mais quelques couples sans enfants peuvent aussi s’y installer. Les familles avec enfants sont orientées, elles, vers un foyer de « France-Terre d’Asile ». Étant donné la difficulté de faire cohabiter des réfugiés de l’Asie du Sud-Est, de l’Europe de l’Est, de l’Afrique et de l’Amérique Latine, la C.I.M.A.D.E. a pris l’option de réserver la maison aux réfugiés africains et latino-américains. Il n’y a pas d’animosité entre ces deux groupes, bien qu’il faille parfois des mois avant que des membres de l’un et de l’autre puissent communiquer en profondeur. La langue, l’histoire, la sensibilité les séparent. Par ailleurs, les Latino-Américains, par peur de l’assimilation, ont tendance à rester entre eux. L’expérience de l’internement les rend méfiants : ils mettent du temps à « arriver » vraiment.

Cette importante analyse repose sur les réponses à l’enquête statistique lancée par l'INED (Institut National d'Etudes Démographiques) et destinée à étudier la véritable importance de leurs handicaps ou la nature et l’ampleur de leurs difficultés. Nous en présentons ici la conclusion.
Deux années d'animation péri-scolaire : évaluation-bilan
Authors:   ECOFAS, Tonnelier Véronique
Published: November 2023

Nous avons rencontré à plusieurs reprises une équipe d'animatrices d'ECOFAS (Association pour le Développement de l'économie sociale et familiale en Région Parisienne) afin qu'elles nous livrent leur expérience dans le domaine de l'animation péri-scolaire.

À une année d'intervalle, elles ont bien voulu nous relater l'histoire de leur action, à savoir : leurs difficultés dans la mise en place de ce nouveau type d’activités, leur première évaluation et comment la reconduction du projet pour l'année 1983-84 leur a permis d'approfondir leur travail et de dresser un bilan.

Pour une psychologie de la réussite
Authors: A. H.G.
Published: November 2023

Hélène Gratiot-Alphandery analyse l'image - le plus souvent pessimiste - des enfants de travailleurs migrants donnée par la majorité des rapports des conseillers d'orientation, des résultats d'examens psychologiques. Elle propose de jeter un nouveau regard sur ces enfants, en tenant compte des derniers travaux de psychologues et ethnologues, ce qui permettrait de renouveler l'image de l'enfant dans les sociétés contemporaines.
Les enfants de l'immigration et les honneurs de la cimaise. Radiographie d'une exposition
Authors: Coulaud Philippe
Published: November 2023

Présentée à la galerie du C.C.I., au cours du premier semestre 1984, l'exposition «Les enfants de l'immigration» a reçu près de 400 000 visiteurs. Caractéristique originale de cette manifestation : la parole laissée aux jeunes immigrés eux-mêmes, à travers de multiples animations (radio en direct, débats sur scène, théâtre, musique, danses et chansons). Une occasion unique pour tester auprès d'un vaste public les effets d'un dispositif de mise en forme et de mise en espace de l'information que l'on peut considérer comme une Première au Centre Georges Pompidou. C'est pourquoi une enquête scientifique a été réalisée auprès de 800 visiteurs de l'exposition. Cet article de synthèse (2) tend à mettre en lumière les stratégies de visite du public et les pratiques au sein de l'exposition.

Les stratégies identitaires des enfants de migrants
Authors: Malewska-Peyre Hanna
Published: November 2023

Migrants-Formation a publié en octobre 1978, dans son n° 29.30 consacré aux adolescents immigrés, un article de Hanna Malewska-Peyre traitant de "l’identité et les jeunes immigrés". Neuf ans après, l'angle d'attaque est un peu différent puisqu'il s'agit ici de stratégies identitaires des enfants de migrants, c'est-à-dire des processus de changement dans les valeurs et les comportements de ces jeunes par rapport à leurs parents et à la société d’accueil.

L’espace et le temps dans la théorie de la modifiabilité cognitive (Programme d’Enrichissement Instrumental). La réanimation spatio-temporelle d’élèves en grand échec scolaire en classe de SES
Authors: Debray Rosine , Prouvost Véronique
Published: November 2023

On apprend tout au long de sa vie, encore faut-il apprendre à apprendre. C’est ce que développe la théorie de Feuerstein. Les expérimentations du Programme d’Enrichissement Instrumental (PEI) conduites, en France, auprès d’élèves de classes de SES et de jeunes adultes en stages d’insertion ou de reconversion confirment la possibilité de ce "redémarrage cognitif". L’inscription dans l’espace et le temps est le premier des apprentissages, condition de tous les autres.

Authors: Tanh
Published: November 2023

Voici exposés les principes qui prévalent dans la société traditionnelle vietnamienne, dans l’attribution des noms et prénoms. Ils sont souvent en contradiction avec les usages français.

L’indispensable aventure de l’adolescence : du conflit intergénérationnel aux risques de la création en milieu transplanté
Authors: Antoni M. , Scotto Jean-Claude
Published: November 2023

L’adolescent issu de parents migrants a plus de difficultés que les autres à faire de son adolescence une période de passage maturante et structurante.

L’ambiguïté des rôles au sein de la famille, l’ambivalence de ses propres choix culturels, les attentes déçues des parents peuvent pousser ces adolescents à se fondre et à s’enliser dans le groupe de leurs pairs sans pouvoir accéder à une identité propre.

D’autres au contraire, et ce sont les plus nombreux, pour s’affirmer, se voient dans l’obligation de créer de nouveaux modèles d’identification.
Condition minoritaire et nouvelles pratiques religieuses
Authors: Oriol Michel
Published: November 2023

Le religieux n ’est qit ’une face du pro¬ blème de la position, de la défense et du développement des identités collectives qui sont en perpétuelle recréation sociale et prennent à contre-pied tous les sché¬ mas évolutionnistes, comme en témoignent les exemples portugais et maghrébin.

Alors que la société américaine accepte la présence de communautés ethniques antagonistes et se revendiquant comme telles, c’est la combinaison d’adhésion à une expression identitaire collective et d’individualisation des choix qui caracté¬ rise désonnais, en France, les pratiques religieuses des minorités issues de l'immigration.

École du quartier ou école dans le quartier. Violences et limites de l'école
Authors: Debarbieux Eric
Published: November 2023

Une enquête approfondie menée auprès de 60 établissements fait apparaître que la violence en milieu scolaire n'est pas essentiellement violence délinquante et exogène, mais surtout violence des élèves entre eux ou violence de l'affrontement pédagogique à l'intérieur du champ clos de la classe.

L'inscription de la violence dans le local développe le repli sur soi et les cloisons internes.

Au-delà du débat ouverture-fermeture, toute stratégie de lutte contre la violence, cette transgression des limites, doit clairement poser ces limites.

A autoestima do adolescente compreende um sentimento de identidade, estruturado a partir de reflexões. Nesse sentido, a autoestima do jovem pode ser enriquecida através de intervenções sociais. Por isso, a Liga Médico-Acadêmica de Pediatria (LIPED), da Universidade Estadual do Oeste do Paraná, campus Cascavel, promoveu uma dinâmica de grupo para fortalecer a autoestima de 86 alunos do 6° ano e 18 alunos do 7° ano, do Colégio Estadual Padre Carmelo Perrone, em Cascavel, Paraná. Foram coletados 103 relatos sobre um dia feliz e 103 relatos sobre um dia triste das suas vidas, destacando-se a tristeza e a felicidade relacionada à família, principalmente à figura materna, e à presença ou ausência de amizades. Portanto, uma rede de apoio ao adolescente demonstrou colaborar para o desenvolvimento da autoestima do adolescente e se constatou a facilidade de execução dessa dinâmica de grupo em uma escola pública e o impacto positivo na vida desses estudantes.
