Authors: Maina Gichuki Joseph , Magak Ngw’ena Gideon , Domnic Marera , Murugi Kanyugo Anne
Published: November 2023

Background: Background: Phytochemicals are plant bioactive compounds that are produced for their protection with some having medicinal value. Craterostigma plantagineum hoscht is a plant that is purported to have medicinal value and is used for treatment of pain, liver and diarrheal ailments. Extensive researches on phytochemicals present in Craterostigma plantagineum hoscht are missing. The aim of this study was to determine qualitative phytochemicals yield in ethanol and aqueous extracts of Craterostigma plantagineum hoscht. Materials and methods: Craterostigma plantagineum hoscht was harvested and allowed to air dry for one month. Grinding into powder form later followed this. Solvents used included 70% ethanol and distilled water. 500mg of Craterostigma plantagineum ground powder was soaked in 70% ethanol for 48 hours, filtered and vaporized in rotary evaporator. Aqueous extraction involved soaking of 500mg of ground powder in 250 millilitre distilled water, set in a shaker for 2 days, filtered, deep frozen for 48 hours and finally freeze dried for 72 hour. Chemicals used to test phytochemicals included 1% gelatin, chloroform, ferric chloride, sulphuric acid, lead acetate solution, magnesium turnings, 10% sodium chloride, acetic anhydride, Mayer’s reagent, ammonia and hydrochloric acid. Results: The yield included flavonoids, Saponins, tannins, cardiac glycosides, phenols, anthraquinones, alkaloids, terpenoids and sterols. Tannins, anthraquinones, flavonoids, sterols, cardiac glycosides, Saponins, and phenols were highly extracted in ethanol while aqueous extract yielded more alkaloids and terpenoids. Conclusion and recommendations: Ethanol extraction yielded more phytochemicals than aqueous. Nonetheless, some phytochemicals were better extracted in ethanol while others in aqueous making the choice of extraction method dependent on the phytochemical of interest.

Authors: Aaboudech Taha Yassine , Znati Kaoutar , Jahid Ahmed , Bernoussi Zakiya , Zouaidia Fouad
Published: November 2023

Plexiform fibromyxoma (PFM) is a rare gastrointestinal tumor, primarily found in the stomach. Esophageal PFM is exceptionally rare. We describe a case of a mid-20s woman with respiratory and swallowing difficulties, revealing a 105x65 mm upper thoracic esophageal submucosal tumor during endoscopy. Biopsy lacked histological evidence of gastrointestinal stromal tumors (GISTs). Post-tumor removal histopathology showed a spindle tumor with plexiform architecture and myxoid-vascular stroma. Immunohistochemistry revealed vimentin and alpha-smooth muscle actin expression, while desmin, c-kit, DOG1, and CD34 were absent, confirming PFM. No recurrence or metastasis appeared during a 6-month follow-up. This case underscores the extreme rarity of esophageal PFM, emphasizing the need for precise diagnostic tools to navigate challenging differential diagnosis.

Parasolnik z Sopotu – (niedoceniony) performer uliczny
Authors: Majchrowski Zbigniew
Published: November 2023

Artykuł jest poświęcony performerowi ulicznemu Czesławowi Bulczyńskiemu (1912–1992), zwanemu Parasolnikiem z Sopotu. Na podstawie skąpych danych biograficznych, biograficznej legendy, relacji prasowych, dokumentacji wizualnej, mediów społecznościowych oraz wspomnień mieszkańców Sopotu autor ukazuje Parasolnika jako queerującego swój wizerunek, wyemancypowanego prekursora perfomansu pasażowego i radykalnego artystę ciała, który funkcjonował w sposób całkowicie niezależny, poza mainstremowymi i alternatywnymi obiegami sztuki. Niepowtarzalny charakter performatywnej aktywności Parasolnika uwypukla zestawienie jego stylu z działaniami innych freaków o artystycznych ambicjach – Krzysztofa Niemczyka z Krakowa, Tomasza Machcińskiego z Kalisza i Ryszarda Kisiela z Gdańska – a także z twórczością profesjonalnego artysty kabaretowego i pisarza Jerzego Afanasjewa. Cross-dressingowe, celowo ambiwalentne i wywrotowe akcje Parasolnika autor interpretuje jako wybiegające obyczajowo poza swój czas eksperymentalne ćwiczenia wolności realizowane w opresyjnej przestrzeni publicznej PRL-u i pracę socjopoznawczą. Wieloletnie zaskakujące przechodniów działania uliczne Parasolnika w Sopocie zostały ujęte jako minimalistyczne performanse interakcyjne i prowokacje inkluzywne, dzięki którym Bulczyński stwarzał afirmatywną atmosferę otwartości na wszelkie rodzaje odmienności.

Les indications d’endoscopie digestive en réanimation ou en soins intensifs en dehors des hémorragies digestives sont nombreuses. La problématique interventionnelle concerne principalement le bilio-pancréatique : drainage des angiocholites et des collections post pancréatite aiguë, ou après transplantation hépatique. L’essor des drainages extra-anatomiques échoguidés par écho-endoscopie et des prothèses d’apposition luminale permet de s’affranchir de techniques plus invasives radiologiques ou chirurgicales et constitue, en cas de succès technique et clinique, en un réel service rendu au patient. Des situations plus courantes comme la mise en place d’une sonde de nutrition, l’évaluation de la gravité endoscopique d’une ischémie mésentérique, la prise en charge d’un volvulus colique ou d’un syndrome d’Olgivie compliqués sont également rencontrées.
The paradigmatic basis of architectural heritage management in the context of the modern philosophy of cultural property conservation
Authors: Gański Włodzimierz , Fleychuk Mariya
Published: November 2023

Conservation of cultural property has been defined as all actions aimed at safeguarding cultural property for the future in order to study, record, retain and restore the culturally significant qualities of the object, site or building with the least possible intervention. Architectural conservation constitutes actions that address the repair, restoration, maintenance and display of historic buildings, enclaves of buildings and sites, as well as their associated accoutrements, such as furnishings and fittings. These actions whether conducted on individual buildings or groups of buildings represent investments in the future of such sites. Such regenerative action at historic buildings and sites usually increases values of adjacent properties and local economic conditions as well. Architectural conservation is widely regarded as the predominant activity within the larger and more diverse field of cultural heritage conservation, which is also referred to as cultural heritage (or resource) management. This field is concerned with the documentation and preservation of all forms of human culture, including tangible artifacts such as architecture, archaeological sites, cultural landscapes, arts and crafts, and other objects of material culture. Architectural restoration and rehabilitation offers new practical, educational and growth stimulus possibilities. In addition, cultural heritage conservation addresses intangible manifestations of human activity, including existing manners and customs (folkways); spiritual practices; and musical, craft and cuisine traditions of indigenous populations, all of which are considered living heritage. The general purview of heritage conservation practice is ever expanding which makes the field both dynamic and open to new participants who bring fresh talent and perspectives to the task. As organized heritage conservation practice expands with each passing year formerly disparate facts and representations of history take on new meaning and significance. In relation to this, both cultural and economic values at heritage sites constantly change. Changes posed by nature and humans on physical cultural heritage ensure constant change as well.

A Holistic Framework for Evaluating QOUL Linking Contemporary Planning Theories Principles
Authors: Salah Riham , Embaby Mohga , Okba Ehab
Published: November 2023

The new urban theories (e.g. sustainable development and smart growth) prioritise inclusive, safe, resilient, and sustainable urban planning protocols to improve the quality of urban life (QOUL). In response, researchers have developed various indicators to assess and monitor QOUL. However, these indicators are not currently linked to contemporary planning theory (CUPT) indicators, representing a limitation in their applicability. Therefore, this study proposes a detailed examination of CUPT principles and their contribution to QOUL to address this limitation. Initially, a comprehensive review of the existing QOUL indicators and CUPT principles is conducted to provide a foundation for identifying conventional QOUL. Then, a comparative analysis is performed to identify gaps and overlaps between the current QOUL indicators and the principles of CUPT. By translating these principles into measurable subjective and objective indicators, we aim to advance the measurement of QOUL. Following this, the extracted indicators from CUPT are added to the final proposal. The proposed framework encompasses six objective sub-dimensions with 17 indicators and four subjective sub-dimensions with 13 indicators. This offers a holistic framework for evaluating QOUL.

In vitro antagonism test of endophytic isolates from the ciplukan plant (Physalis angulata L.) against Ralstonia solanacearums
Authors: Nugraheni Ika Afifah , Mawaddah Inneke Ashri
Published: November 2023

Ralstonia solanacearum was a pathogenic bacteria that causes wilt disease which can cause up to one hundred percent damage to horticultural plants. Therefore, a control effort was needed to overcome this problem. The use of pesticides was an alternative that can be used to suppress the growth of the pathogen R. solanacearum. However, its continuous use poses a high risk to the environment so friendly and safe control efforts are needed. One way was by utilizing endophytic bacteria. This study aims to test the ability of endophytic bacterial isolates from ciplukan plant (Physalis angulata L.) to suppress the growth of the pathogenic bacteria R. solanacearum in vitro. The method in this research includes rejuvenating endophytic bacterial isolates BA2(3), BA3(1), DA1(4) and BU3(5) from ciplukan plants (Physalis angulata L.) obtained from research conducted by Setianah (2020), observations macroscopic and microscopic endophyte isolates, hypersensitivity test of endophytic bacteria on tobacco plants (Nicotiana tabacum L.), then continued with an in vitro antagonist test using the Kirby Baurer technique. Research data shows that of the four candidates, two isolates of endophytic bacteria, namely BA2(3) and BU3(5), showed a negative hypersensitivity reaction which was characterized by the absence of necrosis symptoms in the hypersensitivity test, so these isolates could be tested for antagonists. The results of the antagonist test showed that isolates BA2(3) and BU3(5) had the potential to inhibit the growth of R. solanacearum which had an inhibitory diameter of 3.03 mm and 1.60 mm in the first 24 hours of incubation. It is hoped that the ability of endophyte isolates BA2(3) and BU3(5) to inhibit the growth of the pathogen R. solanacearum can be used as a biological agent to reduce the use of pesticides in treating plant diseases.
A novel free-operant framework enables experimental habit induction in humans
Authors: Gera Rani , Barak Segev , Schonberg Tom
Published: November 2023

Habits are a prominent feature of both adaptive and maladaptive behavior. Yet, despite substantial research efforts, there are currently no well-established experimental procedures for habit induction in humans. It is likely that laboratory experimental settings, as well as the session-based structure typically used in controlled experiments (also outside the lab), impose serious constraints on studying habits and other effects that are sensitive to context, motivation, and training duration and frequency. To overcome these challenges, we devised a unique real-world free-operant task structure, implemented through a novel smartphone application, whereby participants could freely enter the app (24 hours a day, 7 days a week) to win rewards. This procedure is free of typical laboratory constraints, yet well controlled. Using the canonical sensitivity to outcome devaluation criterion, we successfully demonstrated habit formation as a function of training duration, a long-standing challenge in the field. Additionally, we show a positive relationship between multiple facets of engagement/motivation and goal-directedness. We suggest that our novel paradigm can be used to study the neurobehavioral and psychological mechanism underlying habits in humans. Moreover, the real-world free-operant framework can potentially be used to examine other instrumental behavior-related questions, with greater face validity in naturalistic conditions.
Study on the Effects and Methods of Writing Feedback: Focusing on comparison of face-to-face and non-face-to-face writing feedback
Authors:   Korean Association for Literacy, Song Myung Jin
Published: November 2023

This study examined the effects of writing feedback and compared the characteristics of “face-to-face” and “non-face-to-face” writing feedback. Using this, we proposed a writing feedback teaching method. Thus, this study conducted a survey targeting 230 learners pursuing  at Kyonggi University, in the second semester of 2022.
Many learners responded positively to the “effectiveness of writing feedback.” Particularly, they believed that writing feedback was helpful in developing learners’ competencies. Moreover, a survey on “methods of writing feedback” revealed that individual communication with the instructor was an advantage in face-to-face feedback, whereas it was a disadvantage for learners who were not accustomed to communication. Alternatively, being able to view repeatedly was an advantage in non-face-to-face feedback, whereas immediate interaction was a disadvantage.
Therefore, writing feedback should be designed as follows. First, the content of writing feedback should be planned considering the development of learners’ competencies. Second, the method of writing feedback should be implemented by linking face-to-face and non-face-to-face writing feedback.
I believe learners need writing education. If writing feedback is designed to reflect the needs of learners, it could be an effective teaching method.
The Meaning and Effect of Outlining Teaching in College Writing Education
Authors:   Korean Association for Literacy, Lee Boo Soon
Published: November 2023

Outlining is an educational training activity to strengthen writing capabilities that focuses on the exploratory nature and dynamics of the writing process. Based on this understanding, this study aims to explore practical and effective strategies for outlining teaching.
The main errors learners make in outlining are closely related to the requirements of good writing and the core competencies of writing. Therefore, in response to the strategic importance of outlining guidance in writing education aimed at improving learners' writing ability, I proposed a method to strengthen outlining and confirmed its effectiveness.
The strategy to strengthen outlining ability was designed according to two principles: creating and revising an outline through a multi-step process and providing differentiated feedback for each step. This strategy is effective in helping beginners in writing not only internalize the intertextual nature of the writing process and learn the dynamics of thought composition but also experience developmental changes through the process.
A Study on the Literature Education of the Foreign Students Using the Cultural Contents: Centering around Song Ki-sook’s “Uturi － The Alive, Follow Me 1”
Authors:   Korean Association for Literacy, Na Seonhye
Published: November 2023

This study uses Song Ki-sook’s “Uturi － The Alive, Follow Me 1” as a text and thereby, reviews the ways to use diverse cultural contents in the classroom. ‘Uturi’ is the literary work that portrays the actual progression of May 18 Democratic Movement vividly to help the learners to understand the truth and significance of the democratic uprising, while showing how the characters change, and thereby, look back upon themselves and others, responding emotionally to the uprising.
What should be handled in the classroom regarding this work may well be the temporal and spatial background of the work, the main character ‘Hyeondo’, the significance of the being or ‘Uturi’, the borrowing of the legend ‘Uturi’ emerging as an epic strategy to deliver the theme, etc. These discussions may also evolve interestingly and in-depth in reference to such diverse cultural contents as cartoon ‘Uturi’, movie ‘Taxi Driver’, folk tale ‘Baby General Uturi’, ‘Memorable May’ and diverse cultural festivals.
Cultural contents serve as a bridge connecting learners with the literary works and plays a key role in stimulating learners’ interests and sense of subjectivity, and therefore, they may well be more important in the literature education for the foreign students. In other words, they may need to be positively used in the Korean literature education, considering that they allow for an active literary learning and help to create an arena of dialogue facilitating dynamic questions and responses.

Accessing NMDB data using NEST and pandas
Authors: Fuller Nicolas
Published: November 2023

The Neutron Monitor Database (NMDB) was created by teams from 12 different countries in 2008. Data from neutron monitors worldwide is pooled and made available, for many stations in real-time. The NMDB Event Search
Tool (NEST) started as a quick-look interface to the data in NMDB, but by now has become the main interface to all NMDB data. NEST does not only enable you to plot data from one or several NMDB stations in a
very customizable way, it also allows you to retrieve the data in ASCII format for further processing or creating your own plots. Downloading data can be scripted using ‘wget’ or ‘curl’ as documented in
‘3 ways 2 use NEST’. Here we are presenting python functions to read in data from one or several stations directly from NEST into a pandas dataframe. Once your data is in a ‘dataframe’, you can easily
sort, modify or plot data with python.
The Structure Function of Mid-infrared Variability in Low-redshift Active Galactic Nuclei
Authors: Son Suyeon , Kim Minjin , Ho Luis C.
Published: November 2023

Using the multi-epoch mid-infrared (MIR) photometry from the Wide-field Infrared Survey Explorer spanning a baseline of ∼10 yr, we extensively investigate the MIR variability of nearby active galactic nuclei (AGNs) at 0.15 < z < 0.4. We find that the ensemble structure function in the W1 band (3.4 μm) can be modeled with a broken power law. Type 1 AGNs tend to exhibit larger variability amplitudes than type 2 AGNs, possibly due to the extinction by the torus. The variability amplitude is inversely correlated with the AGN luminosity, consistent with a similar relation known in the optical. Meanwhile, the slope of the power law increases with AGN luminosity. This trend can be attributed to the fact that the inner radius of the torus is proportional to the AGN luminosity, as expected from the size−luminosity relation of the torus. Interestingly, low-luminosity type 2 AGNs, unlike low-luminosity type 1 AGNs, tend to exhibit smaller variability amplitude than do high-luminosity AGNs. We argue that either low-luminosity type 2 AGNs have distinctive central structures due to their low luminosity or their MIR brightness is contaminated by emission from the cold dust in the host galaxy. Our findings suggest that the AGN unification scheme may need to be revised. We find that the variability amplitude of dust-deficient AGNs is systematically larger than that of normal AGNs, supporting the notion that the hot and warm dust in dust-deficient AGNs may be destroyed and reformed according to the strength of the ultraviolet radiation from the accretion disk.

Voir et toucher les savoirs depuis les lieux périphériques.
Authors: Lalande Antoine
Published: November 2023

Cet article souhaite interroger la façon d’appréhender les savoirs des sciences sociales depuis des lieux périphériques aux centres de production académiques. En effet, à la différence des études de laboratoire, l’enquête depuis les périphéries n’a aucune certitude que les sciences qu’elle entend observer sont bien présentes sur le lieu d’observation. Dès lors, la principale difficulté de l’enquête n’est pas tant d’accéder au terrain que de comprendre comment « repeupler » les sciences à partir de celui-ci. Ainsi, plutôt que de partir de catégories pré-construites, l’auteur entend ici montrer, à partir d’un travail mené depuis un café militant de l’Est parisien, qu’enquêter par ces lieux nécessite de s’en remettre à une « vision touchante » qui se développe et s’éprouve dans les relations nouées avec les personnes rencontrées.
La proximité aux objets dans l’enquête. Écriture ordinaire et relations de voisinage
Authors: Vassor Mathilde
Published: November 2023

À partir d’une recherche sur la place de l’écriture dans les relations de voisinage, l’article interroge les effets heuristiques d’une enquête menée en suivant un écrit ordinaire que sont les affichettes de voisinage : en quoi faire varier la place des objets et suivre les enchevêtrements dans lesquels les affichettes sont prises permet-il de saisir des manières de vivre diffuses – les relations de voisinage – et d’en analyser leur fabrique ? L’autrice décrit la manière dont les variations autour de l’objet construisent progressivement une optique sur le social. Les affichettes sont considérées tour à tour comme le témoin d’un mode de relation, un objet coexistant avec d’autres modes de communication. Enfin, leur place dans les pratiques est observée à partir d’entretiens qui prennent les relations de voisinage comme focale.

Il tente de montrer comment la démarche de création de savoirs plus sensibles (autrement dit qui conservent la texture multi-sensorielle et relationnelle du contexte de leur élaboration) implique un questionnement de la définition de la réflexivité du·de la chercheur·se dans l’entretien, mais aussi de celle du cadre légitime et des normes habituelles d’exercice de la réflexivité.
Densifier l’analyse des phénomènes communicationnels par l’enquête. Le cas du problème public du congé paternité
Authors: Verquere Laura
Published: November 2023

À partir d’une enquête menée sur les fabriques du problème public du congé paternité auprès des mouvements citoyens (associations féministes et mobilisations de pères) et de l’analyse sémio-discursive des représentations médiatiques, cet article montre ce que l’enquête de terrain peut apporter aux Sciences de l’information et de la communication (SIC), et plus particulièrement au champ de recherche portant sur l’articulation entre médias, espace public et controverse. Nous nous demandons dans quelles mesures l’enquête par le proche permet de densifier l’analyse des phénomènes communicationnels par lesquels les arènes publiques s’organisent et s’édifient ; et ce, de trois façons différentes : en posant la question de l’importance , et en pluralisant et donnant corps aux réalités rencontrées.
L’impact du polymorphisme sexuel sur la déformation primaire de l’œdipe
Authors: Richard François
Published: November 2023

L’auteur propose d’élargir la conception classique du complexe d’œdipe en interprétant les troubles narcissiques limites, chez l’enfant, l’adolescent et l’adulte, comme des déformations inévitables dès lors qu’elles reflètent un œdipe primaire infiniment fluctuant parce que soumis à la pression d’un polymorphisme sexuel infantile indomptable. À partir de cette hypothèse, un regard nouveau est posé sur les formes actuelles du malaise dans la civilisation ainsi que sur les phénomènes transgenres. Le cas clinique d’un adolescent qui découvre, bouleversé, la puissance de son lien archaïque à sa mère, montre que le conflit œdipien dérive souvent d’une folie non psychotique. La discussion de ce cas permet de mieux saisir la fragilité tragique d’un œdipe primaire dont les formes varient selon un ample spectre – ce qui invite le psychanalyste à une écoute et à des modalités d’intervention renouvelées.
Construction identitaire « entre deux »
Authors: Korff-Sausse Simone
Published: November 2023

À partir de son expérience de psychanalyste avec des enfants atteints de handicap, l’auteure étudie la construction identitaire dans ces situations cliniques souvent extrêmes. Quels sont les processus psychiques de la prise de conscience d’une différence pour laquelle le modèle freudien classique de la différence sexuelle ne suffit pas ? L’auteure propose alors l’hypothèse de l’invention d’une nouvelle forme identitaire caractérisée par la multiplicité et la diversité.
Identité sexuée, problématiques de genre et transitions (Quelques questionnements théorico-cliniques…)
Authors: Joly Fabien
Published: November 2023

La problématique des « dysphories de genre », et des enjeux de l’identité sexuée, de ses aléas et des demandes de transitions est un « laboratoire » nouveau, singulier et exponentiel. On posera ici – à partir de deux vignettes cliniques – quelques premiers jalons d’une réflexion tant clinique et technico-thérapeutique (depuis la « demande », la position d’écoute, les enjeux contre-transférentiels et les possibilités d’un processus élaboratif) : qu’au niveau théorique et psychopathologique (plaidoyer pour un « travail d’identité » intégrant la question du sexuel et de la pulsion, mais aussi de « l’autre » et de l’intersubjectivité voire du transgénérationnel dans les processus de subjectivation, le plus loin possible d’un auto-engendrement déniant tout manque et toute altérité) : et enfin de la pleine mesure des multiples dimensions impliquées des images du corps et du travail d’appropriation subjective des expériences et autres mouvements et figurations du corps « en relation »…
Les démocraties sous pression ? L’enjeu stratégique du soldat augmenté
Authors: Bourgois Pierre
Published: November 2023

Au cours des dernières années, plusieurs puissances semblent avoir fait de l’augmentation des capacités physiques comme psycho-cérébrales des combattants un axe fort de leur recherche stratégique. À ce titre, les démocraties apparaissent aujourd’hui sous pression. Alors que la compétition technologique globale les oblige à ne pas se détourner du soldat augmenté, afin d’éviter tout décrochage potentiel, elles ne peuvent dans le même temps ignorer les responsabilités qui sont les leurs, en particulier sur le plan éthique. Face aux multiples débats qui ont émergé, plusieurs États se sont d’ores et déjà engagés dans des réflexions portant sur la limitation et l’encadrement du super soldat. Pourtant, il semble que ces initiatives soient non seulement limitées mais surtout relativement inégales. De fait, comment appréhender le phénomène stratégique du soldat augmenté ? Plus particulièrement, quels sont les enjeux auxquels font face les pays démocratiques au sujet de la question de l’augmentation militaire ?
Deux discours, le silence
Authors: Kahn Laurence
Published: November 2023

L’analyse détaillée de la rhétorique de deux discours, prononcés respectivement en 1985 et 1988 par le Président du Bundestag et le président de la République fédérale d’Allemagne, permet de mettre en évidence, d’une part, le destin des mots expulsés de la langue lorsque revient la mémoire et que l’histoire s’incarne dans la parole, d’autre part, la stratégie psychique permettant d’ouvrir dans l’après-guerre à la « réconciliation » des peuples moyennant un processus de « déréalisation », enfin ce que mobilise dans la psyché collective le débat très conflictuel autour de la distinction entre mémoire et histoire.
Toucher au temps
Authors: Rey Jean-Michel
Published: November 2023

Dans le domaine politique, c’est, plus que l’oubli, le faire oublier qui prévaut. Parfois sur injonction extérieure, plus souvent sur un mode intériorisé, pour des raisons idéologiques générales. Règne en maître la réinterprétation de l’antérieur, ou son invention pure, par la rétroactivité. L’important étant ici les voies vers l’oubli, les modalités par lesquelles un groupe ou une société cherche sans cesse à refaçonner le temps, sans se soucier aucunement de la logique.

Carnet de route
Authors: Tamet Jean-Yves
Published: November 2023

Chaque formation convoque son roman, né de rencontres qui, au fil du temps, organisent un récit et font apparaître rétrospectivement un parcours. Mais chaque trajectoire évolue également dans un contexte, et c’est l’alliage entre les deux que tente d’explorer et de mettre en valeur ce texte. Sortir de l’oubli des moments signifiants.
Appartenance et valorisation
Authors: Lynch Caitrin , Khalifa Jean-Charles
Published: November 2023

Résumé De 2006 à 2011, l’anthropologue Caitrin Lynch s’est immergée dans la vie quotidienne d’une usine de la banlieue de Boston spécialisée dans la production d’aiguilles en acier. Cette entreprise familiale a pour particularité d’employer des travailleurs et des travailleuses dont l’âge médian s’élève à 74 ans. En observant et en interrogeant ces femmes et ces hommes, elle a enquêté sur le sens que revêt le travail pour les personnes âgées aux États-Unis. En plus des revenus que celui-ci leur apporte et qui constituent un complément souvent nécessaire à leurs pensions bien maigres, Caitrin Lynch montre que le travail leur confère un double sentiment d’appartenance à un groupe ( membership ) et de valorisation ( mattering ). Il leur permet ainsi d’échapper à la marginalisation sociale à laquelle ils et elles s’estiment condamné·es en les maintenant dans des réseaux de sociabilité professionnels.
A hierarchical chain-based Archimedes optimization algorithm
Authors: Zhang Zijiao , Wu Chong , Qu Shiyou , Liu Jiaming
Published: November 2023

The Archimedes optimization algorithm (AOA) has attracted much attention for its few parameters and competitive optimization effects. However, all agents in the canonical AOA are treated in the same way, resulting in slow convergence and local optima. To solve these problems, an improved hierarchical chain-based AOA (HCAOA) is proposed in this paper. The idea of HCAOA is to deal with individuals at different levels in different ways. The optimal individual is processed by an orthogonal learning mechanism based on refraction opposition to fully learn the information on all dimensions, effectively avoiding local optima. Superior individuals are handled by an Archimedes spiral mechanism based on Levy flight, avoiding clueless random mining and improving optimization speed. For general individuals, the conventional AOA is applied to maximize its inherent exploration and exploitation abilities. Moreover, a multi-strategy boundary processing mechanism is introduced to improve population diversity. Experimental outcomes on CEC 2017 test suite show that HCAOA outperforms AOA and other advanced competitors. The competitive optimization results achieved by HCAOA on four engineering design problems also demonstrate its ability to solve practical problems.
The Paradox of Educational Inequality in Indonesia
Authors: Zreik Mohamad
Published: November 2023

This chapter examines the causes and consequences of educational inequality in Indonesia, illuminating the intricate relationship between inequality and factors such as society's wealth and the state of the environment. Disparities are analyzed in terms of their location, income, ethnicity, and gender, with special focus on the rural-urban and gender gaps. It delves into the ways in which economic disparity contributes to underdevelopment and poverty. The chapter also highlights the significance of educational disparities in efforts to promote environmental sustainability. Inclusion of the financial sector, infrastructural development, training of educators, and curricular changes are all recommended solutions. This discussion is helpful for academics and policymakers because it sheds light on the monetary and social costs associated with education disparities.
Education and Human Development in the BRICS Countries
Authors: Sasmaz Mahmut Unsal , Bayar Yilmaz
Published: November 2023

Human development is among the major priorities of the country. Therefore, the driving factors of human development are important for the design of optimal policies. In this context, this chapter analyzes the causal relationship between education and human development in the BRICS states over the period of 1990-2021 by means of asymmetric causality test. The results of the asymmetric causality test uncover a bidirectional causal relationship between education and human development in case of both negative and positive shocks.
Revealing the Intercellular Communication Changes of Human Abdominal Aortic Aneurysms at Single-cell Resolution
Authors: Niu Yuqing , Cheng Shaoxian , Zhou Cheng
Published: November 2023

Background:

Abdominal aortic aneurysm (AAA) is a chronic vascular inflammation progression with a high mortality. However, intercellular communication has not been sufficiently explored in human AAA tissue.

Aims:

Here, we investigated available single-cell RNA sequencing data generated from human AAA.

Results:

These cells were divided into 27 clusters and 6 main cell types, such as T-cells, B-cells, myeloid cells, neutrophils, endothelial cells, and fibroblasts. Immune cells were present in AAA tissues more than control. In addition, we established an intercellular communication network and observed a more pronounced enrichment of TGFB1, CCL, VEGF, IL6, and complement pathways in the AAA group compared to the control group.

Conclusion:

Together, our analyses provide beneficial insight into cell–cell communication and expand channels for the effective immunotherapy development of AAA in the future.
