E-training environment for developing Capstone teaching skills for STEM teachers in Egypt
Get PDFThe research investigated the efficacy of utilizing an e-training environment to enhance capstone teaching skills among STEM educators. Conducted at Obour STEM School, Cairo, Egypt, the study employed a quasi-experimental design with 27 randomly selected participants. Three instruments were utilized: a list of Capstone teaching skills, a pre-post achievement test, and an observation card assessing skill acquisition in two main fields: EDP Field and Process Management Field. These fields encompassed eight main skills, subdivided into 64 subskills. The researchers conducted pre- and post-testing, initially administering a 70-question pre-test followed by a month-long online training via Microsoft Teams. The training content aimed to address identified needs based on pre-test results. After the training, participants completed a post-test, which was repeated after another month. Results indicated a statistically significant difference (p<=0.05) between pre-test and post-achievement test scores, favoring the latter, suggesting improvement in Capstone teaching skills. Similarly, there was a significant difference (p<=0.05) between pre-test and post-observation card scores, indicating enhanced skill development. Conclusively, the study demonstrated the effectiveness of e-training, particularly employing the SOLE technique, in enhancing capstone teaching skills among STEM educators. Consequently, the researchers recommended the integration of e-training environments in STEM teacher development programs in Egypt

Méthodologie et résultats : Au total 8640 individus ont été échantillonnés mensuellement de novembre 2012 à octobre 2014. Les mensurations, les dissections, les prélèvements de gonades et les analyses histologiques ont été réalisées au laboratoire. La sex-ratio, la taille de première maturité sexuelle et la période de reproduction ont été déterminées. Le suivi mensuel de l’indice de condition et de l’indice gonadique révèle que la gamétogénèse a lieu de janvier à février et de juillet à octobre. Le repos sexuel est observé pendant les mois de mars à juin et de novembre à décembre. La sex-ratio présente une dominance des femelles par rapport aux mâles avec un rapport femelles et mâles de 1,68 soit 62,74% de femelles et 37,26% de mâles. La différence entre les mâles et les femelles est significative (X2 = 9,58 ; ddl = 8) au seuil de 5%. La taille de première maturité sexuelle est de 57,89 mm chez la femelle et de 66,24 mm chez le mâle. Conlusion et application des résultats : Cette espèce présente deux périodes de ponte dans l’année. Ces résultats pourraient aider les politiques à actualiser les données pour une meilleure planification de la gestion durable des ressources maritimes et initier la conchyliculture.
Objective: The aim of this study is to determine the reproduction parameters of the species of Bivalve Cardium costatum landed at the fishing port of Abidjan by trawlers in order to provide important data in conservation strategies and sustainable management of stocks. Methodology and results: A total of 8640 individuals were sampled monthly from November 2012 to October 2014. Measurements, dissections, gonad samples and histological analyzes were carried out in the laboratory. Sex ratio, size at first sexual maturity and reproductive period were determined. Monthly monitoring of condition index and gonadal index reveals that gametogenesis takes place from January to February and from July to October. Sexual rest is observed during the months of March to June and November to December. The sex ratio shows a dominance of females compared to males with a female to male ratio of 1.68 either 62.74% females or 37.26% males. The difference between males and females is significant (X2 = 9.58; df = 8) at the 5% threshold. The size at first sexual maturity is 57.89 mm in females and 66.24 mm in males. Conclusion and application of results: This species has two laying periods during the year.

Identity Crisis in Strindberg’s Miss Julie and Chekhov’s The Cherry Orchard: A Psychoanalytical Study
Get PDFAugust Strindberg’s Miss Julie and Anton Chekhov’s The Cherry Orchard have always been recurrently analyzed within disputable studies concerning the characters’ psychoanalytic makeup, the characters’ breakdown at the break of a new social class, and a naturalistic, existential approach. Such a foundational approach for analysis is overpoweringly highlighted in the two plays within an unshakable regularity to the assumption that female identities in the two plays have undergone intense turmoil, toppled heavily in the middle of socioeconomic changes with the decline of aristocracy. However, this paper aims to juxtapose and compare the concept of identity crisis in association with the traumatic experiences of the two characters Miss Julie and Mrs. Ranyevskaia through a comparative psychoanalytic approach. It is inexplicable how the two addressed characters grapple with their different circumstances with fractured identities, where they fail to stand up for their social and gender roles and elevate their sense of individuation and selfhood in the middle of the surrounding deteriorations. Through a comparative analysis, this study lays the groundwork needed for exploring, interpreting, and investigating more nuanced reciprocal relationships associated with identity crisis
Assessment of Health Professionals' Knowledge of Risk Factors in the Performance of Home Radiography
Get PDFAim and purpose: The knowledge of health professionals about the potential risks of using ionizing radiation plays an important role in protecting themselves and patients. The use of mobile radiography units poses several threats to workers such as radiation exposure, ergonomic injuries and musculoskeletal disorders from the constant use of lead feet and moving the portable radiography machine. The aim of the study is to highlight the knowledge background of healthcare professionals on radiation and radiation protection. Methodology: 72 questionnaires were distributed and 60 were returned with an overall response rate of 83%. The main sections addressed through the questionnaire were demographic data, knowledge background on radiation dose and radiation protection rules and measures. Statistical analysis of the data was performed using SPSS software. Results: From the results, the deficit of the knowledge background of health professionals on radiation and radiation protection is evident. It emerged that health professionals, especially medical doctors - radiologists have knowledge of the dose received by the patient when performing a chest X-rayin a percentage of 75%, 6.6% stated that they rarely or never use a protective lead apron, 5% of the respondents stated that they never use a personal dosimeter. Conclusion: The guidelines for radiation protection of workers and patients when performing home radiography should be based on the pillars of continuous training of staff, but also on adherence to the very basic principle of justification
Effets socio-économiques de l’adoption des variétés améliorées de mil diffusées au niveau de la plateforme d’innovation de Tingoni (région de Ségou) sur le bien-être des ménages agricoles
Get PDFAu, des changements rapides dus principalement à la pression démographique et à la variabilité climatique sont intervenus ces dernières années. L’augmentation de la densité de population rurale, ne permet plus d’assurer un système durable de production. Pour remédier à ces contraintes, cette étude vise à analyser l’effet de production des variétés de mil Toroniou et Synthétique 006 sur les condition de vie des membres de la plateforme de Tingoni. Elle a été conduite pendant les campagnes 2020-2021, 2021-2022 et 2022-2023 dans 53 exploitations. Elle a consisté à faire un suivi permanent des exploitations pendant les opérations culturales et complétée par les enquêtes individuelles à travers un questionnaire semi-structuré. Les résultats de l’étude ont montré que l’ethnie, la taille de l’exploitation et la superficie n’ont pas de corrélation avec le niveau d’adoption des variétés Toroniou et Synthétique. Cependant, le statut de résidence des producteurs a une corrélation significative avec le niveau d’adoption des technologies. Les rendements moyens sont de 1037 kg/ha pour les adoptants et 627 kg/ha pour les non adoptants. L’analyse de variance a montré une différence hautement significative (P≤0,001) entre les rendements suivant le statut des producteurs. L’analyse du bien-être des membres de la plateforme de Tingoni a montré que 74 % des exploitations adoptantes ont une consommation acceptable contre 42 % pour les non adoptantes. Les conditions liées à l’insécurité alimentaire ont montré qu’environ 68 % des producteurs adoptants sont dans les bonnes conditions contre 58 % de mauvaise condition pour les non adoptants. Les technologies (variétés de mil Toroniou et Synthétique 006) contribuent à l’amélioration des revenus des producteurs. Ces revenus issus de la vente des surplus de production permettent de diversifier la ration alimentaire des exploitations. Par conséquence, contribue au bien-être des membres de la plateforme d’innovation de Tingoni.
In Mali, rapid changes due mainly to demographic pressure and climate variability have occurred in recent years. The increase in rural population density no longer makes it possible to ensure a sustainable production system. To remedy these constraints, this study aims to analyze the production effect of the millet varieties Toroniou and Synthetic 006 on the living conditions of the members of the Tingoni platform. It was conducted during the 2020-2021, 2021-2022 and 2022-2023 campaigns on 53 farms. It consisted of permanent monitoring of farms during cultivation operations and was supplemented by individual surveys through a semi-structured questionnaire. The results of the study showed that ethnicity, farm size, and area do not correlate with the level of adoption of Toroniou and Synthetic varieties. However, the residency status of producers has a significant correlation with the level of technology adoption. Average yields are 1037 kg/ha for adopters and 627 kg/ha for non-adopters. The analysis of variance showed a highly significant difference (P≤0.001) between yields according to producer status. The analysis of the well-being of Tingoni's platform members showed that 74% of adopting farms have acceptable consumption compared to 42% for non-adopters. Food insecurity conditions showed that about 68% of adoptive producers are in good condition compared to 58% of non-adopters. The technologies (Toroniou millet varieties and Synthetic 006) contribute to the improvement of producers' incomes. This income from the sale of surplus production makes it possible to diversify the food ration of farms. As a result, contributes to the well-being of the members of Tingoni's innovation platform
The Mediating Role of Individual Performance in the Interplay between ICTE Appropriation and Educational performance
Get PDFOver the past two decades, higher educational institutions have invested heavily in information and communication technologies (ICT). Since the advent of the Internet, ICTs have significantly impacted university organization, teaching, and learning methods. A key research question concerns the impact of students' appropriation of ICTs on educational performance. Scholars have explored this question both theoretically and empirically but faced two main constraints. First, it is challenging to observe students' ICT appropriation due to unclear definitions. Second, the evolving nature of ICTs makes isolating their effects difficult. This study aims to explore the contribution of students' ICT appropriation to educational performance in universities and to define the role of Individual Performance in the relationship between ICT appropriation and educational outcomes. Based on a quantitative survey of students from public universities in the Casablanca-Settat region, the study used the structural equation method (SEM) with SMART PLS 4.0 software. Data from 185 students revealed a direct correlation between ICT adoption and educational performance, with individual performance acting as an intermediary. The findings indicate that ICT profoundly influences the learning process in higher education. Future research should focus on the individual performance of Moroccan university students and its impact on their educational outcomes. 
Quantification et Caracterisation des Dechets de Mangue au Burkina Faso
Get PDFLe potentiel de déchets issus de la filière mangue au Burkina Faso n’est pas objectivement connu, bien qu’il constitue un enjeu ambivalent du point de vue économique et environnemental. L’objectif de cet article est d’évaluer la disponibilité des déchets issue de la chaine de valeur (production, commercialisation, transformation et consommation des mangues au Burkina Faso. La méthodologie empruntée a consisté à calculer des paramètres de tendance centrale et de dispersion notamment la moyenne, la moyenne des moyenne, la somme des moyennes et l’écart type des données statistiques disponibles au niveau national et à chaque maillon de la filière. Des données secondaires et primaires ont été collectées sur la période de 2016 à 2023 et concernent celles des zones à forte génération de déchets de mangue. Les résultats indiquent que la filière mangue produit en moyenne chaque année entre 100513,66 et 116122,04 tonnes de déchets au Burkina Faso soit entre 46,2% et de 53,4% de la production nationale de mangue fraiche. Par rapport à la totalité des déchets, les pourcentages moyens sont élevés au niveau de la transformation situés à 41%; la production en génère les 30,37%; la consommation locale produit 15% et les exportations 13,59%. Par maillon, au niveau de la transformation, la moyenne des pourcentages moyens des quantités de déchets générés est de 45,35% avec un taux plus élevé de 94,16% et un minimum de 12,5% par rapport aux mangues fraiches, le maillon production en déclassés 15% et 30% au niveau commercial. Cette énorme quantité disponible de déchets recommande de vite trouver une ou des méthodes appropriées pour leur gestion afin d’empêcher les effets néfastes probables sur l’environnement et le vivre-ensemble.
The potential of waste from the mango sector in Burkina Faso is not objectively known when it constitutes an ambivalent issue from an economic and environmental point of view. The objective of this paper is to quantify the availability of waste from the value chain (production, marketing, processing and consumption) of mangoes in Burkina Faso. The methodology used consisted of calculating central tendency and dispersion parameters, in particular the mean, the sum of means, the mean of means and the standard deviation of the statistical data available at the national level and of each individual link. The statistical analysis of secondary and primary data covered the period from 2016 to 2023 and concerns those from areas with high generation of mango waste. The results indicate that the mango sector produces on average, each year, between 100,513.66 and 116,122.04 tons of waste in Burkina Faso, or between 46.2% and more than 53.3% of the production of fresh mango. About the totality of waste, the average percentages are high at the processing level; at 41%, the production generates 30.37%, local consumption produces 15% and the exports 13.54% of total waste. By link, at the processing level, the average percentage of the quantities of waste generated is 45.35% with a higher rate of 94.16% and a minimum of 12.5% compared to fresh mangoes received. This enormous available quantity of waste recommends quickly finding one or more appropriate methods for their management in order to prevent their probable harmful effects on the environment and living together

The Organizational Contribution of the PMO: An Assessment Using Structural Equation Modeling
Get PDFThis research is part of a thesis project that includes two main phases, and it aims to develop and examine a conceptual model to understand and verify the contribution of the PMO to the performance of Moroccan organizations as well as to their level of project management maturity in terms of organization and practices. Thus, the main objectives of this research are: (1) examine the PMO contribution to organizational performance and project management maturity, but also (2) contribute to the solidification of the theoretical basis of the project management school. For this, a quantitative approach was adopted, where a questionnaire was administrated online for three consecutive months. Firstly, the president of the PMI Moroccan chapter was contacted to request their collaboration. Secondly, a direct interaction was carried out with people evolving in project management within organizations that have a Project Management Office (PMO) and who could answer the questionnaire through the professional network "LinkedIn". Two hundred and five (205) responses were received, of which seventy-six (76) were discarded because the respondents declared the non-existence of a PMO within their organizations or it exist for less than three years. Finally, one hundred and twenty-nine (129) responses were considered usable and represent our final database from which we proceeded to a set of analyzes and tests. Two-stage data analysis was followed. First, a descriptive and exploratory analysis of the data collected was performed using SPSS. Next, a confirmatory analysis using structural equation modeling was carried out with the help of SmartPLS to examine the validity of the constructs of the model and to test the hypotheses. The results of this study provide a solid basis for linking PMO functions to organizational contributions. The study concluded that the PMO through its functions contributes to organizational performance and project management maturity. It also highlights the mediating effect of project management maturity. However, the possible moderating effect of PMO type on structural relationships could not be verified
