    Performances Des Projets Routiers Et Vulnérabilités Institutionnelles Au Sénégal Et A La Gambie : Approche Stratégique Du Management Du Risque

    Full text link
    Cette étude analyse comment les faiblesses institutionnelles ; fragmentation administrative, retards de paiement, absence de cadre réglementaire et faible culture du risque affectent la gestion du risque et la performance des projets routiers au Sénégal et en Gambie. Une approche mixte a été mise en œuvre sur cinq ans, combinant une enquête auprès de 300 professionnels du secteur routier, 20 entretiens semi-directifs avec des responsables institutionnels, ainsi qu’une analyse documentaire de contrats, audits et rapports techniques afin d’assurer une triangulation méthodologique. Les résultats montrent que les risques institutionnels influencent davantage la performance des projets que les risques techniques ou environnementaux. Les principaux freins relevés sont l’absence de cadre unifié de gestion du risque, l’hétérogénéité des outils, la faible coordination inter-agences et la fréquence des retards de paiement, entraînant des retards, surcoûts et litiges. La performance des projets routiers dépend surtout de la qualité de la gouvernance institutionnelle. Le renforcement des cadres réglementaires, l’amélioration de la coordination, la digitalisation du suivi des risques et la promotion d’une culture proactive du risque constituent des réformes essentielles pour améliorer la résilience et la réussite des projets

    Être Empêchée De Devenir « Vodoussi » : Souffrance Psychique

    Full text link
    Le conflit est une « lutte de tendances, d’intérêts » (Sillamy, 2019), antinomiques. Il traduit de ce fait, une situation où un sujet est soumis à des forces de directions antagonistes et approximativement d’énergie égale. Quand le conflit apparaît inextricable, l’angoisse naît, et le mal être, voire la souffrance psychique peut s’installer, d’où l’intérêt de la présente étude.Cette étude vise à analyser et comprendre les significations des éléments psycho socioculturels, responsables de la souffrance psychique. Afin d'atteindre cet objectif, nous avons adopté une approche qualitative (analyse de cas clinique), comprenant des outils comme l’entretien semi-directif, l’observation clinique couplée de l’épreuve projective du « dessin libre de la ligne de vie ».Aux vues des analyses des données, nous relevons, que la découverte du secret de ses parents et surtout le fait d’être « Vodoussi » c’est à dire « fille du fétiche Vodou » font trauma, car cela semble brutal. Il apparaît un empêchement dans la transmission des liens et des devoirs coutumiers transgénérationnels. L’on peut constater une intrication des éléments issus des coutumes, du christianisme et les connaissances issues de la culture occidentale, ce qui est angoissant d’ailleurs. Manifestement, il apparaît un sentiment d’inquiétude, de malaise, de peur voire d’impuissance face à d’éventuelles représailles du fétiche « Vodou ». Ce qui semble d’ailleurs faire émerger le un sentiment de menace et d’anéantissement du moi. Le risque d'annihilation semble entraîner un morcellement accru de ce moi primaire. L’analyse du dessin confirme l’effondrement narcissique avec un profonde dégradation de l’image de soi. En conclusion, cette étude arbore l’importance des enveloppes psychiques culturelles dans la construction et la stabilité des assises identitaires, gage du bien-être chez un sujet

    Enhancing Hydrophilicity of 100% Cotton Fabric Using Negative Corona Plasma: Correlation Study between Energy Dose and Gap Distance Optimality

    Full text link
    This study investigates the characterization and optimization of surface treatment for 100% cotton fabric using a wire-plane Dielectric Barrier Discharge (DBD) system operated with Negative Corona DC voltage. The primary objective was to determine the optimal electrical and geometric parameters for enhancing surface hydrophilicity without damaging the material. The methodology involved systematic Current-Voltage (I-V) characterization to identify stable discharge modes and subsequent plasma irradiation of cotton samples at varying time intervals and gap distances. Results indicated that the system successfully transitioned from a spark discharge to a stable non-thermal DBD mode at larger gap distances (greater than or equal to 3.9 cm) due to the dominance of gas gap impedance. Functionally, the plasma treatment significantly improved wettability, reducing water absorption time by over 60% through the functionalization of polar groups on the cellulose surface. The efficiency of activation was governed by the cumulative energy dose, with 30 minutes identified as the optimum irradiation time. Furthermore, a gap distance of 4.5 cm yielded slightly superior absorption times compared to 3.9 cm, implying that gap geometry influences the chemical composition of reactive plasma species. These findings offer a controlled protocol for sustainable textile finishing

Digital storybooks combine text, images, sound, and interactivity, which can stimulate children's cognitive, social, and emotional engagement. This study aims to examine the role of digital storybooks as an innovation in PAUD learning and their effectiveness in enhancing children's learning interest. Digital storybooks have proven effective in improving children's understanding, memory, and social and language skills by providing an interactive learning experience. This research uses a qualitative approach with a literature study method to explore the concept of digital transformation in PAUD education and the development of digital storybooks. The results show that digital storybooks can support children's fundamental development and facilitate their thinking process and attention during learning. This study also provides practical guidelines for PAUD teachers to integrate digital storybooks into the curriculum, considering pedagogical principles and children's developmental stages

    Organizational Mindset Shift and Innovativeness of Oil and Gas Firms in South-South, Nigeria

    Full text link
    This study examined the nexus between the change in the organisational mindset and the innovativeness in oil and gas and companies located in Rivers State, Nigeria. The problem that led to the study was most organisations find it hard to generate process innovation despite adopting the modernization and restructuring programmes, attributed mainly to, inflexible mindsets and lack of leadership reinforcement. The main objective was to explore the relationship between level of organisational changes in the mind set and the innovations potential and the role of leadership reinforcement to support this relationship. The study was supported in the theory of Dynamic Capability and Transformational Leadership which explains the effect of the cognitive adaptation in innovation. Positivist research philosophy was modified and research design was cross-sectional survey. Using the stratified sampling technique, the study made used of 351 respondents as the sample size which was determined using Yemane's formula. The structured questionnaire were used to collect data and the descriptive statistics and Spearman Rank Correlation Coefficient were used to analyse the data with level of significance of 0.05. The results showed that there is a positive and significant association between the dimensions of organisational mind set changes (growth mind set, adaptive learning, openness to change, and collaborative orientation) and process innovation capability. Theoretically, the study added value to the literature as it incorporated leadership support to the dynamic capability framework, whereas, managerially, the focus is on developing adaptive mindsets by supporting them through supportive leadership practises. The study suggests regular mindset renewal programmes that are led unceasingly in order to maintain innovation

    Increasing The Yield Of Kerosene-Gasoil Fraction From Crude Oil Under The Influence Of Oxygen Containing Additives

    Full text link
     It is known that in the atmospheric rectification of crude oil, the addition of oxygen containing (oxygenates) additives in small quantities increases the yield of light fractions from oil. This fact does not occur during distillation without oil additives.Various oil mixtures and individual light (Satskhenisi) and heavy (Mirzaani) oils from Eastern Georgia under atmospheric distillation conditions were taken as research objects.Residues from the production of cognac alcohol were used as oxygenates.The study of the possibility of increasing the yield of fractions from various oil mixtures in the presence of the aforementioned oxygenates was conditioned by the fact that oil refineries mainly process mixtures of oils, and not individual oils. Nevertheless, studies were conducted using individual Satskhenisi (light) oil and Mirzaan (heavy) oil.Increasing the yield of fractions from oil has been studied in the case of using chemically pure individual organic compounds as additives. Similar compounds are often liquid components of alcohol production, and it is the fact that has led to their use as oxygenates during atmospheric distillation of oil

    Intelligent Solar Tracker: An Innovative Approach to Enhancing the Quality of Education through University Governance

    Full text link
    In a context where higher education is constantly evolving, the integration of innovative technologies becomes a strategic lever to strengthen university governance. This work presents the design and implementation of an automated solar tracker aimed at maximizing the energy efficiency of educational installations, particularly in institutions facing frequent power outages. Entirely developed individually with limited resources, this project demonstrates that an educational model based on hands-on experimentation and practical problem-solving can significantly improve the quality of teaching.The article is structured around three fundamental axes of university governance: the pedagogical axis (enhancing project-based learning), the infrastructural axis (sustainable use of energy), and the managerial axis (empowerment and individual initiative). Experimental results show an increase of over 25 percent in energy yield compared to a fixed photovoltaic system, confirming the relevance of such a device.Linked to a previous article published in IJPSAT on the energy efficiency of the solar tracker, this contribution illustrates the synergy between technological innovation and educational governance. It advocates for the recognition and funding of personal projects that have a significant academic impact. This approach encourages universities to support innovative initiatives driven by individual motivation, which can foster a more dynamic and effective learning environment.Ultimately, this work highlights how integrating technology within university governance can not only improve resource management but also enhance pedagogical outcomes. It provides a practical example of how innovation and governance converge to promote sustainable development and academic excellence in higher education
