Des services réseaux aux plateformes du numérique et aux services multisectoriels
Authors: Kofman Daniel , Jutand Francis
Published: October 2024

Nous rentrons dans une nouvelle phase de la transformation numérique. Dans la continuité d’une transformation en silos, par secteur d’activité, nous passons à une phase qui ouvre la voie aux services multisectoriels, transversaux aux divers marchés verticaux. L’énorme potentiel de création de valeur est identifié et ne cessera de se développer vu les possibilités d’innovation qui sont ainsi ouvertes ; les risques pour les acteurs et pour la souveraineté des pays sont multiples. Cette évolution est rendue possible par une série de nouveaux paradigmes, dont la softwarisation et virtualisation des infrastructures, la convergence progressive entre les réseaux et le cloud , l’évolution des interfaces, les jumeaux numériques et l’IA, ainsi que l’ouverture des réseaux et systèmes aux acteurs externes. Ce dernier point transforme les infrastructures du numérique dans des plateformes de services, permettant à ces derniers d’être conçus et établis en temps réel, en orchestrant des composants d’acteurs multiples, pour répondre dynamiquement à des besoins spécifiques et évolutifs.Nous présentons dans cet article une vision intégrée de ces diverses évolutions.
L’existence se laisse-t-elle rabattre dans l’immanence ?
Authors: Freudiger Marc-André
Published: October 2024

Dans les pays européens marqués par les Lumières et la postmodernité, la place de Dieu dans la société n’a cessé de se rétrécir. S’il est toujours des croyants, chrétiens ou non, et des communautés religieuses attachées à lui, pour une large proportion de contemporains le monde a perdu tout vis-à-vis transcendant et s’est aplati. Mais pouvons-nous vraiment nous passer de transcendance ? À l’aide de la notion d’« englobement des contraires » mise en évidence par Jean-Pierre Dupuy, Marc-André F reudiger * entend montrer que la pensée de l’immanence recèle des plis cachés de transcendance, que le débat se joue entre transcendance et autotranscendance, et que le christianisme y a un atout à jouer .
L’hypothèse du marché adaptatif et les risques géopolitiques sur les marchés agricoles
Authors: El Montasser Ghassen , Belhoula Mohamed Malek , Naoui Kamel , Guesmi Khaled
Published: October 2024

Cet article examine l’efficience des marchés de matières premières agricoles en utilisant la mesure ajustée d’inefficience des marchés (AMIM). À travers divers outils statistiques tels que les régressions MCO, Logit, et Tobit, ainsi que les tests GSADF et les tests des résidus récursifs, nous explorons la capacité de l’hypothèse du marché adaptatif (AMH) à expliquer les comportements explosifs des prix des matières premières agricoles lors des bulles spéculatives et de la pandémie de COVID-19. Conformément à l’AMH, nos résultats soulignent la nature variable dans le temps de l’efficience des marchés à terme agricoles. De plus, nous observons une réaction non uniforme de l’efficience de certains marchés agricoles face aux chocs événementiels. Notamment, en contradiction avec les périodes de crises financières, l’épidémie de COVID-19 a un effet plus prononcé sur l’inefficience de certains marchés à terme agricoles tels que le maïs et le soja, comparé aux marchés du blé, de l’huile de soja et de l’avoine. Ces résultats ont des implications importantes en termes d’allocation d’actifs et de choix des investisseurs pendant les périodes d’instabilité sanitaire et financière.
Faire son temps
Authors: Bernateau Isée , Libeau Mégane
Published: October 2024

La prison est source de violence par la contrainte qu’elle impose sur le temps et l’espace des détenus. Elle empêche toute possibilité d’investissement et d’appropriation spatiotemporelle qui permettrait de créer un lien de continuité entre la vie à l’extérieur et à l’intérieur. Par ailleurs, cette violence risque d’aboutir à un état d’indifférenciation, lui-même source de violence. La différence n’étant plus admise par l’institution carcérale, les corps se déchaînent pour conserver une limite ébranlée. Aussi, la contrainte spatio-temporelle imposée fait émerger une dynamique mortifère dans le discours. La répétition apparaît alors comme symptôme de cette claustration psychique. Mais des issues existent pour s’extraire de cette violence ou survivre malgré elle, comme l’écriture, la révolte ou la haine.
La prépondérance du clergé catholique dans la société haïtienne au cours de la seconde moitié du xixe siècle
Authors: François Mickenson
Published: October 2024

À partir de la signature du concordat de 1860, le clergé catholique, composé en grande partie par des ecclésiastiques d’origine bretonne, exerce une influence considérable en Haïti pendant toute la seconde moitié du xixe siècle. Contrairement à la France, où l’adoption de lois laïques entraîne un déclin de l’influence de l’institution cléricale, en Haïti, cette institution s’efforce de préserver la morale catholique face à la croissance de la communauté protestante et aux idées anticléricales. Les ecclésiastiques imposent le catéchisme dans les écoles publiques haïtiennes, s’opposent au vodou et promeuvent le mariage religieux. Cependant, à la fin du xixe et au début du xxe siècle bien que des lois laïques ne soient pas adoptées en Haïti, l’Église voit progressivement diminuer son influence au profit de la communauté protestante, ceci en raison de l’influence croissante des États-Unis et du début de l’affirmation d’une certaine « haïtianité ». Cette quête de l’identité haïtienne sera désormais au cœur des travaux de recherche portant sur la première moitié du xxe siècle haïtien.
Stories of Migrant Smuggling: The Soft Power of Djiboutian Smugglers
Authors: Lauret Alexandre
Published: October 2024

This article analyses the links between the recruitment of new generations of smugglers and storytelling of the nocturnal “adventures” of former smugglers in Djibouti. Such accounts make it possible to study the imaginaries and discourses of success surrounding the figure of smuggler. To do this, the article draws on a corpus of stories collected from various actors (smuggler, official, henchman), with each account highlighting the various praiseworthy qualities of such a figure. However, this positive vision of an outlaw should be considered against the backdrop of the Djiboutian political context, characterised by, on the one hand, the privatisation of state rents by a micro-elite, and, on the other hand, the marginalisation and impoverishment of part of the population. This situation has two consequences. First, it means that the smuggler indirectly represents a political figure of protest in an authoritarian context. Second, these stories have a direct impact on the recruitment of a new generation of smugglers. Out-of-school young people join the networks of smugglers, thus strengthening the already established power of the network bosses.
Kierkegaard à l’écoute de la nature
Authors: Delage Armande
Published: October 2024

À partir de la lecture des Discours de 1847 et de 1849 sur le lis des champs et l’oiseau du ciel ainsi que d’extraits des Journaux et Cahiers de Notes courant de 1835 à 1854, l’article entend préciser le rapport que Søren Kierkegaard conçoit entre l’individu et la nature. Si la nature est parfois décrite avec un certain lyrisme, le propos de Kierkegaard s’éloigne toutefois des penseurs romantiques : la nature en effet n’est comprise qu’à partir d’un rapport intérieur et premier à Dieu, qui doit faire voir, dans le silence et la solitude, ce monde du vivant traversé par l’obéissance et la nécessité. À cet égard, c’est le discours de l’Évangile – qui s’oppose au discours du poète, à celui du physicien et, plus généralement, à la parole trop souvent vaine et bavarde de l’être humain – qui aide l’individu à entendre la nature et l’accord divin qu’elle recèle. La nature se révèle ainsi au sein d’un rapport dialectique entre le silence et la parole, la solitude et l’altérité, comme le lieu d’une possible constitution de soi devant Dieu.
L’Année du lièvre : le bonheur de la solitude dans les forêts de la Finlande
Authors: Seppälä Jaakko
Published: October 2024

Le retrait hors de la ville dans un environnement nature paisible est un thème souvent abordé dans l’art et la littérature des pays nordiques. Il s’accompagne fréquemment de la recherche d’une solitude volontaire considérée comme l’antidote authentique au stress, à l’aliénation et à la corruption associés à la vie urbaine moderne. L’isolement reste cependant un défi majeur des sociétés des pays nordiques. L’article analyse cette problématique dans le film L’Année du lièvre (Jäniksen vuosi, 1977) du réalisateur finlandais Risto Jarva, figure de proue de la nouvelle vague de son pays qui a adapté sur l’écran le roman à succès d’Arto Paasilinna connu en France sous le titre Le lièvre de Vatanen.
Happy voluntary solitude? Notes on a Nordic theme
Authors: Stadius Peter
Published: October 2024

Cet article décrit trois thèmes reliés au concept nordique de solitude heureuse et choisie. Le premier est le besoin d’un espace personnel et du temps associé au désir de construire une relation avec la nature nordique. Le deuxième est l’idée d’indépendance et d’autonomie qui est souvent connectée à une suspicion de toute forme redevance sociale somme signe potentiel de faiblesse et de limitation de la liberté personnelle. Troisièmement, l’article soulève la question de solitude imposée ou négative comme un défi des sociétés nordiques. En faisant appel à la théorie d’individualisme étatique (Trädgårdh), l’analyse explore les connexions entre la solitude heureuse et désirée et la solitude subie typiques aux sociétés Nordiques.
A Corpus Study of Dyslexic University Students’ L2 Writing Processes
Authors: Radar Laurie , Gilquin Gaëtanelle
Published: October 2024

Second/foreign language (L2) writing is a critical skill for university students, and one that has attracted a great deal of attention in the literature on academic writing. Yet, one aspect that has received relatively less attention so far is the writing processes of language learners with dyslexia in this context. This study investigates the L2 writing processes of high-functioning dyslexic university students compared to their non-dyslexic counterparts, focusing on pausing and revision behaviours. The data come from a learner corpus representing the writing processes in addition to the written products. The participants are French-speaking learners of English who wrote two texts in English while keystroke logging technology captured their writing processes in real time. The analysis of the data reveals that dyslexic learners exhibit longer overall pausing time and more frequent pauses within words than the control group, indicating potential challenges with word-level processing in L2. They also exhibit longer overall revision time as well as longer mean revision duration than non‑dyslexic learners. Qualitative analysis reveals differences in editing approaches. While dyslexic learners engage in a non-linear editing process, non‑dyslexic learners follow a more linear process. These findings may be indicative of the heavy cognitive load that dyslexic students arguably experience when managing writing processes in L2 contexts.
Restaurants et plateformes de livraison : une approche comparative des stratégies des restaurants traditionnels et rapides
Authors: Lebayle Sterenn
Published: October 2024

Cet article s’intéresse aux relations entre restaurants et plateformes de livraison. Sur la base d’une enquête qualitative, il met en évidence deux stratégies d’intégration de la livraison par les restaurateurs. D’une part, les restaurants traditionnels adoptent une stratégie opportuniste qui se caractérise par l’absence d’investissements destinés à soutenir la livraison, des volumes limités par les capacités de production disponibles, mais une tolérance à un niveau élevé de commissions. D’autre part, les restaurants rapides adoptent une stratégie plus volontariste, qui se caractérise par des volumes de production plus importants mais une moindre tolérance aux commissions, reportées sur les consommateurs et dont le niveau est étroitement négocié avec les plateformes.Classification JEL : L22, L83, L87.
A Review of Electron Microscopy Studies of the Brain in Schizophrenia
Authors: Brown, Jr. James S.
Published: October 2024

In previous work, the author demonstrated that two-thirds of the miRNA expressions associated with asbestos exposure in mesothelioma, especially the oncogenic miRNAs, are similarly expressed in schizophrenia brain tissue. No epidemiological evidence links schizophrenia to asbestos, a naturally occurring material often small enough to qualify as a nanoparticle (NP). This review investigated whether any microscopic study of brain tissue in schizophrenia observed inflammatory NPs of any chemical composition. Transmission electron microscopy (TEM) combined with x-ray energy dispersive spectroscopy is the accepted method for identifying the smallest NPs. However, the review found that no TEM study has used sufficient methods to identify NPs in schizophrenia brain tissue. The review also shows that schizophrenia risk is associated with urban air pollution and neuroinflammation and that NPs in urban air pollution can cause neuroinflammation. Research in this unexplored area of schizophrenia neuropathology may reveal new environmental exposures that might cause schizophrenia.

Published: October 2024

Creating customized applications for the biological domains has made designing nanomaterials a high research priority. Indeed, existing patterns in the literature indicate an absence of comprehensive evaluations that explicitly highlight the state of knowledge about the design and manufacturing of nanomaterials. The performance of nanoparticles (NPs) is affected by various aspects, including size, shape, surface charge, and microstructures. It has also been discovered that these properties depend on how they are synthesized. The principles, sample preparation procedures, and outcomes of the characterization techniques employed to study these nanomaterials varied somewhat. As a result, this book chapter aims to thoroughly analyze current developments in nanomaterials for biomedical engineering, focusing on the selection of nanomaterials, instruments, preparation methods, and characterization techniques employed in nanomaterial design. Important uses of these nanomaterials are also briefly covered, including wound healing, drug delivery, and tissue regeneration.

Effect of Limonene on the Tensile Properties and Chemical Changes of Natural Rubber Products
Authors: Yang Sia Yee , Lai Nai Yeen Gavin , Chen Ruey Shan , Tarawneh Mouad A. , Yu Lih Jiun
Published: October 2024

The durability and functionality of medical rubber products made from natural rubber or poly (cis-1,4-isoprene) are essential in medical and healthcare applications. However, natural rubber products are prone to degradation over time, which can compromise their performance. This study investigates the impact of limonene on the degradation of natural rubber, focusing on the material’s physical and chemical properties. To achieve this, natural rubber samples were prepared and exposed to different concentrations of limonene oil (20%, 40% 60%). The effect of limonene on the natural rubber was assessed by measuring the changes in tensile strength, physical size of samples, stability and chemical composition over immersion times of 30, 60 and 90 minutes. The findings of this study revealed that the immersion of natural rubber in d-limonene led to a significant reduction of tensile properties due to chain scission and bond breaking as well as cross-linking within the rubber. These mechanical alterations were more distinct with the longer immersion times and the higher limoneone concentrations. Additionally, the samples exhibited noticeable dimensional changes with greater concentrations of d-limonene leading to more substantial swelling and ultimately causing a reduction in tensile strength. FTIR-ATR spectroscopy analysis had also revealed chemical modifications in the rubber's structure, particularly related to carbonyl groups. This study provides valuable insights into the vulnerability of natural rubber to limonene-induced degradation. It highlights the need for further research and formulation to enhance medical-grade rubber products' performance for SDG-3.

'I will come again with my partner'
Authors: Di Mattia P.
Published: October 2024

Many things come to our minds when we think about HIV/AIDS. Among these are the two words "resistance" and "stigma". The resistance comes from our patients who find it difficult to share their burden with a partner/significant other. The stigma attached to the HIV/AIDS condition comesfrom the community as a whole. While traditionally the extended African family has provided a support and safety net for its members in time of need, it appears as if the HIV epidemic has affected even this effective system. This review explores the above aspects so as to help us to be more open with our patients and to, perhaps, find together with them the way to oyercome the 'premature death' caused by their HIV+ status.

Comparative Analysis of Impact of Different Skill-training Methods among Medical Students: A Cross-sectional Study
Authors: Rukadikar Charushila , Saiyad Shaista , Mahajan Neeraj , Gupta Sangeeta , Das Arani , Gangwar Anil , Singh Avinash , Rukadikar Atul
Published: October 2024

Background:

The development of practical skills is crucial in medical education, with various teaching-learning (T/L) methods such as Demonstration-Observation-Assistance-Performance (DOAP), Peyton’s four-step approach, and See One Do One Teach One (SO-DO-TO) being employed to enhance students’ competencies in handling medical devices.

Objective:

This study aimed to evaluate the efficacy of DOAP, Peyton’s approach and SO-DO-TO methods on skill performance of 1st-year MBBS students in using a sphygmomanometer, audiometer, and electrocardiogram (ECG).

Methodology:

A cross-sectional study was conducted among 126 1st-year MBBS students, who were randomly divided into three groups (n = 42). Each group was trained using one of the three T/L methods on specified competencies. Skill acquisition was assessed through an Objective Structured Practical Examination (OSPE), and perceptions were gauged through a Likert Scale questionnaire.

Results:

Students trained using Peyton’s method scored the highest in OSPE with a mean score of 7.35 (standard deviation [SD] = 2.19), compared to 5.72 (SD = 1.62) for DOAP and 5.83 (SD = 1.37) for SO-DO-TO. The differences in scores were statistically significant (P < 0.01) between the groups. Perception data indicated that both students and faculty rated Peyton’s method highest in overall satisfaction, effectiveness, and comfort, despite its slightly higher time consumption.

Conclusion:

Peyton’s four-step approach significantly enhances medical students’ skill acquisition and satisfaction compared to DOAP and SO-DO-TO methods. Integrating multiple teaching strategies, as seen in Peyton’s method, can offer a more comprehensive and effective learning experience. Future studies should investigate the long-term impacts and applicability of these methods across various medical disciplines.
Combination of peritoneal flap and buccal mucosa graft vaginoplasty after vaginectomy due to recurrent planocellular vaginal cancer
Authors: Saratlija Žana , Gotovac Ante , Duvnjak Mario , Bačić Boris
Published: October 2024

Primary vaginal cancer is rare, and the optimal approach has not yet been determined. First-line treatment can be radiotherapy or surgery. Surgical treatment is often mutilating and it requires reconstructive surgery. There are many vaginal reconstructive techniques, but none of them showed unequivocal superiority. A 40-year-old woman with planocellular vaginal carcinoma grade I underwent surgical excision of tumor combined with adjuvant radiotherapy. A year after the provided therapy, she experienced a local relapse of vaginal carcinoma. A multidisciplinary team for gynecological tumors once again suggested surgical treatment. Fallopian tubes, uterus, and vagina were removed laparoscopically, and the reconstruction was made using the combination of peritoneal flap and buccal mucosa graft (BMG). To our knowledge, this is the first case describing a combination of peritoneal flap and BMG for the creation of neovagina after total vaginectomy. It can be one of the reconstructive options when the peritoneal flap itself is not enough to cover the entire defect.

The mass media campaign for the detection of hyperglycemia in pregnancy (HIP) via screening, management, and prevention is a significant component of this collaboration to reduce the impact of hyperglycemia on maternal-fetal health and have insight on postpartum follow-up (PPFU) trends.

Materials and Methods:

WDF-GDM Project encompassed an extensive mass media campaign across 29 cities in 10 regions of Pakistan. The primary objective was to establish a national standard for screening and diagnostic standards of HIP, training healthcare providers in blood glucose (BG) screening, treatment, PPFU, as well as disseminating information about pre-conception counseling. The DIPSI method, which is a single-step, non-fasting oral glucose tolerance test with a diagnostic threshold of 140 mg/dL (7.8 mmol/L), was employed as a screening and diagnostic test.

Results:

A total of 17,392 pregnant women of diverse ethnic backgrounds attended antenatal visits; 77.2% (n = 13,417) underwent BG screening based on DIPSI criteria, irrespective of the period of gestation. The overall prevalence of HIP was 35.7% with gestationally impaired glucose tolerance at 25.7%, and gestational diabetes mellitus (GDM) at 9.97% postpartum, approximately 4767 women were eligible for PPFU. Among these, 7% experienced fetal loss. Of the 2376 women who completed PPFU, 81% were normoglycemic, 9% had impaired fasting glucose, 8% had impaired glucose tolerance, and 2% were diagnosed with diabetes. About 75% of women who had hyperglycemia during pregnancy reverted to normoglycemia postpartum, while a small percentage continued to have persistent diabetes.

Conclusion:

This study highlights a GDM prevalence of 9.97% in Pakistan and depicts the positive outcome where many women returned to normoglycemia after childbirth. Factors such as previous pregnancies, body mass index, and history of fetal loss were identified as contributors to the development of hyperglycemia during pregnancy. The WDF-GDM initiative’s approach and comprehensive methodology provide better insights for future maternal healthcare strategies in similar settings nationally and globally.
Unveiling the Veil of Cognitive Bias in Forensic Medicine Decisions

Published: October 2024

The practice of forensic medicine and pathology, as other specialties that are based on cognitive abilities, is greatly impacted by cognitive bias. In this article, the effects of cognitive bias on forensic pathologists are emphasized with a particular focus on how opinions on different parts of death report might be distorted by irrelevant information, including the circumstances of death. The forensic professionals are encouraged to use structured methods for making decisions that give weight to medically pertinent data and reduce the impact of unimportant background information. The article promotes the development of frameworks for policies and training programs that lessen cognitive bias in the hope of improving the objectivity and dependability of forensic findings. Reducing cognitive bias in forensic medicine is essential for maintaining the credibility of forensic science as well as for ensuring that people are treated fairly in the legal system.

Hot section components of gas turbines are exposed to a high operating temperature environment. To protect these components, thermal barrier coatings (TBC) are applied to their surfaces. Yttria-stabilized zirconia (YSZ), which is widely used as a TBC material, faces limitations at temperatures above 1200℃. To mitigate these issues, research has focused on adding lanthanide rare earth oxides and tetravalent oxides to prevent the phase-transformation of the monoclinic phase in zirconia. This study investigated the effects of varying TiO2 content in Nd2O3 and Yb2O3 co-doped YSZ composites. Increasing TiO2 content effectively suppressed formation of the monoclinic phase and increased the thermal degradation resistance compared to YSZ in environments over 1200℃. These findings will aid in developing more thermally stable and efficient TBC materials for application in high-temperature environments.

Published: October 2024

This study investigated the optimal process conditions and mechanical properties of Cu-10Sn alloys produced by the powder bed fusion (PBF) method. The optimal PBF conditions were explored by producing samples with various laser scanning speeds and laser power. It was found that under optimized conditions, samples with a density close to the theoretical density could be fabricated using PBF without any serious defects. The microstructure and mechanical properties of samples produced under optimized conditions were investigated and compared with a commercial alloy produced by the conventional method. The hardness, maximum tensile strength, and elongation of the samples were significantly higher than those of the commercially available cast alloy with the same chemical composition. Based on these results, it is expected to be possible to use the PBF technique to manufacture Cu-10Sn products with complex 3D shapes that could not be made using the conventional manufacturing method.

Friction welding, which uses heat and plastic flow to join metals, is expanding across industries due to its ability to weld heterogeneous alloys and simple process. However, process research is essential for materials with complex geometries, and limited research has been conducted on friction welding between cast and sintered metals. This study analyzed the mechanical properties and microstructural evolution of the joint by controlling the rotational speed and friction pressure, which affect the removal of the heat-affected zone in friction welding of casted SCM440 and sintered F-05-140. Hardness mapping and microstructure observations with material transition were performed to investigate the correlation between phase behavior and welding conditions. These results are anticipated to reduce costs and improve the mechanical properties of key mobility components.

The AlSi10Mg alloy has garnered significant attention for its application in laser powder bed fusion (L-PBF), due to its lightweight properties and good printability using L-PBF. However, the low production speed of the L-PBF process is the main bottleneck in the industrial commercialization of L-PBF AlSi10Mg alloy parts. Furthermore, while L-PBF AlSi10Mg alloy exhibits excellent mechanical properties, the properties are often over-specified compared to the target properties of parts traditionally fabricated by casting. To accelerate production speed in L-PBF, this study investigated the effects of process parameters on the build rate and mechanical properties of the AlSi10Mg alloy. Guidelines are proposed for high-speed additive manufacturing of the AlSi10Mg alloy for use in automotive parts. The results show a significant increase in the build rate, exceeding the conventional build rate by a factor of 3.6 times or more, while the L-PBF AlSi10Mg alloy met the specifications for automotive prototype parts. This strategy can be expected to offer significant cost advantages while maintaining acceptable mechanical properties of topology-optimized parts used in the automobile industry.

Human dependence, on the plants grown on soil and the threat posed by contaminated soil to the ecosystem and general public has become a source of concern. The health risks caused by heavy metals concentration to the study area were evaluated. Fifteen (15) plant samples and soil samples each from the study area were collected and analyzed using an Energy Dispersive X-ray Fluorescence Spectroscopy (EDXRF) for Lead (Pb), Cadmium (Cd), Chromium (Cr), Nickel (Ni), Copper (Cu), and Zinc (Zn). The Measured concentrations of these heavy metals were in the order of Cd>Ni>Cu>Zn>Pb>Cr for the plant samples and Cr>Cd>Ni>Cu>Pb for soil samples with Cd and Cr as the highest contributors to cancer risk in term of the carcinogenic risk estimate. The Health Hazard Index value for all pathways were found to be 7.34 x 10-1 making non-carcinogenic risk component less significant to the adult population and in case of children, the Hazard Index value was 1.21, a value greater than unity (1), which present a severe non-carcinogenic risk component to children living in the study area. The carcinogenic risk was found to be 8.68 x 10-6 implying that 1 person in every 5882 adults may be affected and 1 in 2725 children may be affected (9.6 x 10-5) These carcinogenic risk values were both higher than acceptable values.
