Inflammatory periodontal diseases are one of the most common dental diseases in the world, along with dental caries. In the modern concept of the development of inflammatory periodontal diseases, one of the important roles is assigned to the body's immune response to the action of periodontal pathogenic microorganisms. In modern scientific literature, the concept of cytokine development of inflammatory periodontal diseases has been formed and substantiated. Evaluation of the cytokine profile of oral and gingival fluids allows us to determine the activity and severity of the disease. Well-founded immunological and molecular genetic mechanisms for the development of inflammatory periodontal diseases, associated with the influence of cytokines, make it possible to adjust the complex treatment of inflammatory periodontal diseases, determine the direction of personalized therapy for patients, determine the effectiveness of the treatment and the prognosis of the disease.
Sparking creativity: Encouraging creative idea generation through automatically generated word recommendations
Authors: Wise Talia A. , Kenett Yoed N.
Published: July 2024

Creative block is a familiar foe to any who attempt to create and is especially related to “writers block”. While significant effort has been focused on developing methods to break such blocks, it remains an active challenge. Here, we focus on the role of semantic memory structure in driving creative block, by having people get “stuck” in a certain part of their semantic memory network. We directly examine whether we can “pull out” a participant from where they got “stuck” in their semantic memory, breaking their creative impasse. Our Associative Creativity Sparker (ACS) is a cognitive network science-based online tool that aims to spark creative ideas and break creative impasse: Once a participant runs out of ideas in a creative idea generation task, word recommendations are suggested to prime new ideas. These word recommendations are either towards or away from previous ideas, as well as close or far from the target object, based on a conceptual space extracted from the participants responses using online text analysis. In Study 1, 121 participants use the ACS to generate creative alternative uses for five different objects and completed creativity and Gf tasks. In Study 2, we repeat the design of Study 1, but further examine the impact of writing experience on the ACS, by examining 120 novice and 120 experienced writers. Across both studies, our results indicate that the location of word recommendations affects the fluency and originality of one’s ideas, and that novice and experienced writers differently benefit from these word recommendations.

A Study on the Development Aspect and Tasks of Human Rights Education in Japan
Authors: Lee Jung-Hi ,   The Society of Korea and Japan Education
Published: July 2024

本研究は、日本における人権教育の展開を検討し、その特徴と課題を明らかにすることに目的がある。そのために、文献研究を通して検討した結果、日本の人権教育が展開されてきた特徴として、次の3点が挙げられる。第一に、日本における人権教育は「同和教育」から始まり、多様な社会的弱者を包摂する形で収斂している。第二に、「国連人権教育10年」に素早く対応し、法制度の整備を進めており、国連の「人権教育のための世界計画」の共同提案国として、国際社会が求める教育を導いている立場にある。第三に、文部科学省は毎年「人権教育・啓発白書」を発行しており、「人権に関する知的理解」と「人権感覚」を通して実践的な行動ができる人間を育成するための「人権教育の構造」を提示するなどの教育的努力を行っている。一方、日本の人権教育が直面している課題として、政府から独立した国家人権機構(国内人権機関)の設立が急務である。そして、グローバル社会の進展に対応した人権教育の導入が必要であろう。また、地方自治体が人権教育の推進政策の策定に一層努力し、人権教育がより体系的かつ制度的に行われるようにしなければならない。これらを克服することで、日本は国際的な地位にふさわしい人権保障を実現し、「日本の人権のガラパゴス化が進む問題」を解決していくことができるだろう。// The purpose of this study was to examine the development of human rights education (HRE) in Japan and to reveal its characteristics and tasks. Through a literature review, we examined three characteristics of the development of HRE in Japan. First, HRE in Japan has converged from ‘Dowa (anti–discrimination) education’ to include various socially disadvantaged groups. Second, Japan promptly engaged with the ‘United Nations Decade for Human Rights Education,’ establishing a legal framework and leading the way as a co–proposer of the ‘United Nations World Programme for Human Rights Education’. Third, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) annually publishes a ‘White Paper on Human Rights Education and Awareness,’ aiming to cultivate individuals capable of practical actions through intellectual understanding and awareness of human rights, as outlined in the Structure of HRE. Meanwhile, one of the challenges confronting HRE in Japan is the pressing necessity to establish a ‘National Human Rights Institution’ independent of the government. And it seems necessary to introduce HRE in response to the development of global society. Moreover, it is imperative for local governments to exert greater efforts in crafting policies aimed at advancing HRE, thus facilitating its systematic and institutionalized integration. By surmounting these challenges, Japan can attain human rights assurances aligned with its international stature and address the issue of “the Galapagosization of human rights within Japan.”

Published: July 2024

Background. Non-Hodgkin lymphoma (NHL) represents a diverse group of lymphoid tissue cancers, predominantly arising from B-cells, T-cells, or natural killer cells. The accurate diagnosis of NHL subtypes is crucial, given their varying clinical behavior and treatment responses. This study focuses on the application of immunohistochemistry (IHC) in diagnosing and classifying NHL, comparing its efficacy to traditional hematoxylin and eosin (H&E) staining methods. Methods. Conducted at Al-Sadr Teaching Hospital, Basrah, this cross-sectional study involved 48 newly diagnosed NHL cases in 2015. Patients were initially examined using H&E-stained sections from lymph nodes and extranodal tissue biopsies. IHC staining, employing a range of primary antibodies, was then used to confirm diagnoses and subtype NHL cases. Results. The study revealed a predominance of diffuse large B-cell lymphoma (DLBCL) at 50%. Other subtypes that were identified included mantle cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma, MALToma, peripheral T-cell lymphoma, and follicular lymphoma. The IHC method proved critical in identifying specific NHL subtypes, which were not detectable by H&E staining alone, such as mantle cell lymphomas and peripheral T-cell lymphomas. The study highlighted discrepancies with regional studies, emphasizing variations due to sample size and regional factors. Conclusion. Immunohistochemical staining is an indispensable tool for accurately diagnosing and classifying NHL, complementing H&E staining. This study underscores the need for a comprehensive diagnostic approach, including a panel of antibodies, to optimize the diagnostic process and ensure accurate treatment planning.

Background and objectives. One of the leading causes of disability and death among the population is type 2 diabetes mellitus (T2DM), which is characterized by persistent hyperglycemia. The disease is associated with disorders including oxidative stress and resistance to insulin action, which are involved in the progression of other diabetic complications. Such complications strongly rationalize the need for advanced treatment strategies. Considering the antioxidant, and anti-inflammatory in addition to cytoprotective properties of erythropoietin (EPO), it may offer a new potential strategy for the management of these disorders in diabetic patients. This review aims to explore the effects of EPO on oxidative stress and insulin resistance and its impact on glucose metabolism to guide healthcare professionals to a novel approach for controlling diabetes complications. Materials and methods. This review was conducted by analyzing studies involved with oxidative stress, resistance to insulin, and glucose metabolism in T2DM published in Cochran Library, PubMed, and Google Scholar until February 2024. Results. EPO shows promising beneficial effects in the management of these diabetes-associated disorders. Conclusion. With this beneficial effect of EPO, it is considered a strong candidate and area of development for the creation of new choices in the management of diabetes.

Para compreender melhor a trajetória de crescimento da agricultura brasileira, é preciso entender o movimento da produtividade de diferentes classes de produtores dentro do país, ou seja, verificar se os produtores mais pobres estão convergindo em produtividade com os mais ricos. A partir do modelo de fronteira estocástica, comparam-se os ganhos de produtividade total dos fatores (PTF) de três diferentes estratos de produtores agrícolas no Brasil. Utilizando dados dos Censos Agropecuários 2006 e 2017, no nível microrregional, estimam-se tanto o progresso técnico (PT) quanto o crescimento de eficiência técnica (CET) da agricultura brasileira para diferentes tamanhos de propriedades. Os resultados sugerem que avanços tecnológicos estão presentes em todos os tamanhos de fazendas, concentrando-se nos maiores produtores, o que contribui para divergência de produtividade no Brasil. Além disso, o aumento da ineficiência indica que fazendas de menores portes não têm sido capazes de absorver o progresso tecnológico.

O objetivo deste trabalho é resgatar a perspectiva de análise macrossetorial da seguridade social. A emergência da seguridade e a inter-relação entre as políticas de previdência social, assistência social e saúde são analisadas, em um primeiro momento, de uma perspectiva histórica e conceitual, mobilizando as categorias analíticas que informam tal debate. Em seguida, a partir de uma revisão de estudos e pesquisas sobre a relação entre desigualdade de renda e mortalidade, morbidade, deficiência e dependência, foi possível informar sobre as interfaces entre diferentes tipos de desigualdade, bem como sobre as relações mútuas entre as políticas públicas da seguridade social que buscam enfrentá-las. Após identificar dificuldades tanto empíricas como conceituais para levar a cabo análises macrossetoriais, propõe-se a mobilização dos conceitos de complementaridade institucional e interdependência, visando favorecer uma melhor avaliação das influências setoriais recíprocas tanto em processos institucionais como em seus resultados.
Pedagogy of care in online teaching and learning environments at tertiary institutions through the eyes of Freire
Authors: Pietersen Doniwen
Published: July 2024

Making the most of online or hybrid teaching platforms is essential to making sure that, in the Fourth Industrial Revolution (4IR), higher education settings in developing universities and places are not left behind. While a number of the technological platforms adopted during the Covid-19 lockdown have the potential to reach more kids, they have also overloaded educators and pupils. Therefore, it seems ironic that the same technology that makes it possible for higher education to offer online courses also frequently impedes student progress and places restrictions on the pedagogy of teachers. Regardless of format, the teaching and learning encounter should not come at the expense of caring for the actual student in the ever-changing hybrid teaching model that most tertiary institutions have since adopted. Therefore, the interest of this article is on how ‘care pedagogies’ might improve online teaching and learning at developing universities. In this sense, the role of university teachers should be reflected not only by the number of students engaged in class content, but also by the embodied cultural capital that students bring to online, face-to-face and hybrid learning spaces.
Chronicling participants’ understanding and experiences of integrating ICT into the teaching of geography in South African schools
Authors: Gubevu Bongumusa , Mncube Vusi
Published: July 2024

This article examines geography teachers’, parents’ and learners’ understanding and experiences of the integration of Information and Communication Technologies (ICTs) in the teaching of that subject. The study was guided by the TPACK-SAMR model, which proved to be a reliable tool for measuring the extent of ICT integration. The purposive sampling technique that was employed enabled the researchers to identify participants for the research study related to the importance of integrating ICTs into the teaching and learning of geography. The article draws its purpose from the integration of technologies into the teaching of geography as a means of preparing and equipping learners who take this subject with the type of skills required in the 21st-century job market. Surprisingly, the research findings revealed that some teachers still do not feel comfortable to integrate diverse technologies into their teaching of geography, perceiving it as time consuming. Their unwillingness to become digital citizens and conform to the demands of the Fourth Industrial Revolution (4IR) is a drawback, as are learners’ inappropriate use of ICTs (visiting irrelevant, unwanted sites instead of downloading subject-related content). To empower learners to adopt and use ICTs as valuable tools and solutions on their learning journey drastic changes are required, particularly on the part of curriculum planners in geography.
The World Bank’s neoliberal agenda and inclusive education in post-apartheid South African schools
Authors: Mnisi Nomsa , Mathebula Thokozani
Published: July 2024

Globally, the World Bank’s neoliberal agenda has reframed inclusive education through its investment projects and inclusive policies, thus begetting unevenness and social inequalities. Accordingly, in South Africa, the World Bank’s neoliberal investment projects and inclusive policies exacerbate the exclusion of learners in schools. The critical theory framework is adopted as a lens to explore the extent to which the World Bank’s neoliberal education agenda meets the end goals of democracy and social justice in post-apartheid South Africa. A critical analysis of the World Bank’s inclusive education policies points to a neoliberal agenda that fosters liberalisation instead of human rights; a policy that propagates privatisation instead of universal education; learners’ emancipation barricaded by investment projects that favour deregulation instead of regulation; and illusive social change due to neoliberal public policies in post-apartheid South African schools. Ultimately, the authors argue that the World Bank’s incoherent, inconsistent and ambiguous neoliberal education agenda does not speak to its intended recipients, namely the poor, unprivileged and excluded learners in post-apartheid South African schools. A recommendation thus put forward is that the World Bank should redirect its investment projects and revise its inclusive policies in the quest to spearhead universal and free public education.
Secondary school students' perceptions of the 21st -Century 4Cs in Zimbabwe
Authors: Goto Ottilia , Goto Jameson
Published: July 2024

The volatile, uncertain, complex and ambiguous future world has highlighted the importance of critical thinking, collaboration, communication, creativity and innovation (4Cs) in today’s classrooms. Framed by the Partnership for 21st-Century Learning (P21) Learning and Innovation theme, the study investigates the perceptions of the 4Cs by secondary school students from four schools in Zimbabwe. Two hundred and thirty-six (236) students participated in this quantitative study. Data were collected using online and paper questionnaires. Exploratory and first-order confirmatory analysis revealed a four-factor model with excellent fit indices. The second-order confirmatory factor analysis confirmed that the individual 4Cs were sub-constructs of a higher latent factor, Learning and Innovation (4Cs), where the students strongly endorsed collaboration, followed by communication, critical thinking, creativity, and innovation in decreasing magnitude. Age has a significant influence on critical thinking. The findings highlight the need for teachers to embed critical thinking and creativity acivities within collaborative and communication learning activities.
The use of Van Hiele’s geometric thinking model to interpret Grade 12 learners’ learning difficulties in Euclidean Geometry
Authors: Mudhefi Fungirai , Mabotja Koena , Muthelo Dimakatjo
Published: July 2024

The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners. As a result, the purpose of this article is to interpret Grade 12 learners’ learning difficulties in Euclidean geometry. We use Van Hiele’s geometric thinking model and Hoffer’s skills to argue an interpretation of learning difficulties in Euclidean geometry as a focal point towards creating effective teaching and learning of this important topic. This explanatory sequential mixed-methods approach involved 60 Grade 12 learners who wrote a geometry test and completed a questionnaire based on Van Hiele’s geometric thinking levels. In addition, semistructured interviews were conducted with a sample of 12 learners and four educators to investigate their views about geometry learning difficulties. The findings of the study revealed that learners had poor conceptualisation of properties of shapes, visualisation skills, circle theorems and geometry terminology, resulting in them experiencing learning difficulties. The recommendations are that, during instruction learners should be given the opportunity to manipulate real geometric objects to enhance their visualisation and visual thinking skills. In addition, we recommend that educators should teach level-specific geometry vocabulary to enable learners to understand concepts at different Van Hiele’s levels. Furthermore, we recommend that educators should use constructivist teaching approaches that encourage learners’ conceptual understanding instead of traditional methods that promote rote memorisation of geometric facts. Educators should develop learners’ broad knowledge of geometry to overcome geometry-related errors and misconceptions.

Published: July 2024

La variabilidad climática y la degradación del suelo, el agua y la biodiversidad afectan la calidad de vida de las comunidades rurales y urbanas del país. Para contribuir a la solución de la crisis ambiental global, en la última década las tendencias del mercado y las organizaciones internacionales han fomentado el enfoque hacia la agricultura regenerativa (AR), que es una orientación holística y flexible de principios y prácticas que conllevan a la conservación, regeneración y restauración de los suelos mediante el mejoramiento de la salud del recurso edáfico, el uso eficiente del agua, el aumento de la biodiversidad y la contribución en la disminución de las emisiones de gases de efecto invernadero, entre otros, lo anterior sin afectar la productividad ni los ingresos de los agricultores. La AR, se centra en la salud del suelo, la cual se refiere a la capacidad de los suelos, de sostener y dar vida a múltiples sistemas naturales y servicios ecosistémicos para mantener o mejorar la producción primaria de alimentos, la biodiversidad, el agua, la captura de carbono, la calidad del aire, y los ciclos elementales de la naturaleza. Los sistemas de producción de café en Colombia con prácticas de manejo sostenible favorecen la fertilidad del suelo, y con esto la productividad, rentabilidad y resiliencia frente a la variación climática. Las comunidades caficultoras, cuentan con las recomendaciones provenientes de la investigación para la implementación de prácticas de AR en sus sistemas de producción, sin embargo, es necesario avanzar hacia la investigación en nuevas tecnologías y una mayor aplicación y apropiación de conocimientos por parte del caficultor, con el fin de lograr el mejor beneficio desde los ámbitos social, cultural, económico y ambiental, y allí el Servicio de Extensión es vital para transferir las prácticas de manejo recomendadas a los agricultores.

Solar Flare Ribbon Fronts. II. Evolution of Heating Rates in Individual Flare Footpoints
Authors: Kerr Graham S. , Polito Vanessa , Xu Yan , Allred Joel C.
Published: July 2024

Solar flare ribbon fronts appear ahead of the bright structures that normally characterize solar flares, and can persist for an extended period of time in spatially localized patches before transitioning to “regular” bright ribbons. They likely represent the initial onset of flare energy deposition into the chromosphere. Chromospheric spectra (e.g., He i 10830 Å and the Mg ii near-UV lines) from ribbon fronts exhibit properties rather different to typical flare behavior. In prior numerical modeling efforts we were unable to reproduce the long lifetime of ribbon fronts. Here we present a series of numerical experiments that are rather simple but which have important implications. We inject a very low flux of nonthermal electrons (F = 5 × 108 erg s−1 cm−2) into the chromosphere for 100 s before ramping up to standard flare energy fluxes (F = 1010−11 erg s−1 cm−2). Synthetic spectra not only sustained their ribbon-front-like properties for significantly longer: in the case of harder nonthermal electron spectra, the ribbon front behavior persisted for the entirety of this weak-heating phase. Lengthening or shortening the duration of the weak-heating phase commensurately lengthened or shortened the ribbon front lifetimes. Ribbon fronts transitioned to regular bright ribbons when the upper chromosphere became sufficiently hot and dense, which happened faster for softer nonthermal electron spectra. Thus, the lifetime of flare ribbon fronts are a direct measure of the duration over which a relatively low flux of high-energy electrons precipitates to the chromosphere prior to the bombardment of a much larger energy flux.
Mixing of Hot Shocked Plasma with Cold Gas in Nova YZ Ret 2020

Published: July 2024

The origin of bright X-ray emission lines that appear late in a nova eruption remains largely a puzzle. We present two high-resolution X-ray grating spectra of the classical nova YZ Ret, observed 77 and 115 days post-eruption, using XMM-Newton and Chandra, respectively. Both spectra feature resolved emission lines blueshifted by v = –1500 km s−1 and broadened by σ

v
= 500 km s−1. The two spectra are well described by a collisionally ionized plasma of kT ∼ 70 eV that dimmed by a factor of ∼40 between the two exposures. The spectra also show narrow radiative recombination continua (RRCs) of C+4, C+5, and N+5, indicating the interaction of the hot ionized plasma with cold electrons of kT ∼ 2 eV. The high-n Rydberg series of C+4 is anomalously bright, allowing us to measure the electron density through continuum lowering, which is in agreement with the He-like N+5 density diagnostic of n

e
= (1.7 ± 0.4) × 1011 cm−3. The high population of these high-n levels constitutes the best evidence to date of charge exchange (CX) with neutral H in an astrophysical ionized plasma. The remarkable fact that the velocity and plasma temperature are the same after 38 days, despite the high density and decreasing flux, is evidence for ongoing heating. We suggest the heating is due to a reverse shock in the nova ejecta, which forms a thin X-ray shell. The narrow RRCs and CX are attributed to direct mixing with cold gas, which overtakes the hot plasma either from the shock front or through the contact discontinuity.

Effective temperatures, surface gravities, and iron abundances were derived for 109 stars observed by the K2 mission using equivalent width measurements of Fe i and Fe ii lines. Calculations were carried out in local thermodynamic equilibrium using Kurucz model atmospheres. Stellar masses and radii were derived by combining the stellar parameters with Gaia Data Release 3 parallaxes, V magnitudes, and isochrones. The derived stellar and planetary radii have a median internal precision of 1.8% and 2.3%, respectively. The radius gap near R

Published: July 2024

The Small Magellanic Cloud (SMC) shows a large variation in ultraviolet (UV) dust extinction curves, ranging from Milky Way (MW) like to significantly steeper curves with no detectable 2175 Å bump. This result is based on a sample of only nine sight lines. From Hubble Space Telescope Space Telescope Imaging Spectrograph and IUE spectra of OB stars, we have measured UV extinction curves along 32 SMC sight lines where eight of these curves were published previously. We find 16 sight lines with steep extinction with no detectable 2175 Å bump, four sight lines with MW-like extinction with a detectable 2175 Å bump, two sight lines with fairly flat UV extinction and weak/absent 2175 Å bumps, and 10 sight lines with unreliable curves due to low SMC dust columns. Our expanded sample shows that the sight lines with and without the 2175 Å bump are located throughout the SMC and not limited to specific regions. The average extinction curve of the 16 bump-less sight lines is very similar to the previous average based on four sight lines. We find no correlation between dust column and the strength of the 2175 Å bump. We test the hypothesis that the 2175 Å bump is due to the same dust grains that are responsible for the mid-infrared carbonaceous (polycyclic aromatic hydrocarbon) emission features and find they are correlated, confirming recent work in the MW. Overall, the slope of the UV extinction increases as the amplitudes of the 2175 Å bump and far-ultraviolet curvature decrease. Finally, the UV slope is correlated with N(H i)/A(V) and the 2175 Å bump and nonlinear far-ultraviolet rise amplitudes are anticorrelated with N(H i)/A(V).
Forecast of Joint Analysis of Cosmic Shear and Supernovae Magnification from the CSST and LSST
Authors: Cao Ye , Hu Bin , Yao Ji , Zhan Hu
Published: July 2024

Cosmic shear and cosmic magnification reflect the same gravitational lensing field. Each of these two probes are affected by different systematics. We study the auto- and cross-correlations of cosmic shear from the China Space Survey Telescope and cosmic magnification of supernovae from the Large Synoptic Survey Telescope. We want to determine to what extent, by adding the magnification data, we can remove the systematic bias in cosmic shear measurements. We generate mock shear/magnification maps based on the correlation between different tomographic bins. After obtaining the corrected power spectra, we adopt the Markov Chain Monte Carlo technique to fit the theoretical models and investigate the constraints on the cosmological and nuisance parameters. We find that, with only the cosmic shear data, there are 1σ biases in the σ
8 and intrinsic alignment model parameters. By adding the magnification data, we are able to remove these biases perfectly.
Observational Evidence for Hot Wind Impact on Parsec Scales in Low-luminosity Active Galactic Nuclei
Authors: Shi Fangzheng , Yuan Feng , Li Zhiyuan , Su Zhao , Ji Suoqing
Published: July 2024

Supermassive black holes in galaxies spend the majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow have the potential to play an important role in active galactic nuclei (AGN) feedback. Direct observational evidence for these hot winds with temperatures around 10 keV, has been obtained through the detection of highly ionized iron emission lines with Doppler shifts in two prototypical low-luminosity AGNs, namely M81* and NGC 7213. In this work, we further identify blueshifted H-like O/Ne emission lines in the soft X-ray spectra of these two sources. These lines are interpreted to be associated with additional outflowing components possessing velocity around several 103 km s−1 and lower temperature (∼0.2–0.4 keV). Blueshifted velocity and the X-ray intensity of these additional outflowing components are hard to explain by previously detected hot wind freely propagating to larger radii. Through detailed numerical simulations, we find the newly detected blueshifted emission lines would come from circumnuclear gas shock-heated by the hot wind instead. Hot wind can provide a larger ram pressure force on the clumpy circumnuclear gas than the gravitational force from the central black hole, effectively impeding the black hole accretion of gas. Our results provide strong evidence for the energy and momentum feedback by the hot AGN wind.

Published: July 2024

Human activities are causing rapid biodiversity loss across ecosystems, affecting human wellbeing and crucial ecosystem services. Traditional biodiversity monitoring tools cannot keep up with the increasing demands of monitoring due to their limited spatial or temporal coverage, high costs, and lack of taxonomic expertise. Thus, implementation of novel molecular monitoring methods (MoMs) such as environmental DNA (eDNA) and DNA metabarcoding, are necessary.

MoMs offer significant benefits for biodiversity monitoring and environmental assessment: high sensitivity and accuracy, non-invasive sampling, broad taxonomic range and cost and time efficiency. However, the diverse methodological approaches within MoMs lead to poor comparability between studies and surveys, highlighting the need for standardized assessments.

We used the Technology Readiness Level (TRL) framework to evaluate the maturity of MoMs, providing a structured assessment of their readiness for routine use. In a systematic literature review 420 articles fulfilling the study criteria were assessed and both individual studies and method categories ranked according to the TRL scale. The findings revealed a growing number of studies, particularly in aquatic environments, with most studies validating MoM technologies on a small scale but lacking large-scale system demonstrations. Aquatic eDNA-based methods targeting fish showed overall higher technology readiness compared to other sample types and taxa, and applications of MoMs ranked into the highest TRL were predominantly freshwater studies.

Key barriers to the broader implementation of MoMs to monitoring include the need for international standards, better quantitative estimates, and comprehensive reference libraries. National and international cooperation is crucial for establishing common standards, ensuring reliable and comparable results, and expediting the routine use of MoMs in biodiversity monitoring. Recent efforts towards international standardization are encouraging, but further coordinated actions are necessary for the global implementation and acceptance of these methods.

Authors: Le Roux Nicolas , Thoreau Julie-Jane
Published: July 2024

Quel rôle jouent les opérateurs de l’État dans la transition alimentaire ? Comment insufflent-ils les coopérations et comment épaulent-ils les acteurs locaux dans le lancement d’initiatives ambitieuses pour améliorer l’accès à une alimentation de qualité dans les quartiers de la politique de la ville ? Nicolas Le Roux, responsable du pôle Ville productive et créative à l’Agence nationale de rénovation urbaine (ANRU), et Julie-Jane Thoreau, cheffe de projet à la direction générale déléguée politique de la ville de l’Agence nationale de cohésion des territoires (ANCT), apportent des éléments de réponse.

Pour une église à l’écoute de la vie
Authors: Pelletier Anne-Marie , Baujard Monique
Published: July 2024

La liberté accordée aux femmes de recourir à une interruption volontaire de grossesse (IVG) est une question très sensible. Les débats politiques sont souvent fort violents et les positions extrêmement tranchées. Le magistère catholique a toujours fermement condamné le recours à l’avortement. La réflexion gagne pourtant à mieux entendre la parole des femmes. La défense de la vie et de la « dignité humaine » ne peut que profiter de cette voix qui témoigne d’une « histoire blessée ».
Les profondeurs d’un mythe, Hayao Miyazaki
Authors: Goffart Juliette
Published: July 2024

À partir du film testament d’Hayao Miyazaki, Le garçon et le héron , cet article revisite l’ensemble de l’œuvre de cet artiste qui a révolutionné le cinéma d’animation. Il révèle la cohérence et la profondeur mythique d’un univers hanté par l’impérialisme guerrier, le désastre écologique, les métamorphoses de l’enfance à travers les épreuves du deuil et de l’ambivalence humaine.
La naissance et les débuts de la documentation professionnalisée : entre réflexions professionnelles et volontarisme étatique
Authors: Baude Catherine , Krumnov Marie-Pascale
Published: July 2024

La création de l’ADBS en 1963 s’inscrit dans une longue histoire, celle de la documentation professionnelle. Cet article retrace sa genèse, depuis l’essor de la science et des revues au xix e  siècle, en passant par l’émergence du concept de documentation, l’essor des centres spécialisés, les publications, la mise en place d’un enseignement dédié, les nouveaux services, les métiers, les grandes figures… Il met en évidence le lien entre le développement, aux marges des bibliothèques, de services dédiés à l’information spécialisée et la démarche de professionnalisation de la fonction documentaire. Il souligne les enjeux stratégiques que les États (États-Unis en tête, Europe, France en particulier) n’ont pas manqué de relever, dans un contexte où l’informatique s’impose dans le domaine professionnel.
Sainte-Anne de Jérusalem : un séminaire grec melkite catholique au service de l’Unité ?
Authors: Bouwen Frans
Published: July 2024

Cet article examine la contribution du Séminaire de Sainte-Anne à Jérusalem (1882-1967) à l’identité, à la pensée théologique et à la vocation œcuménique de l’Église grecque melkite catholique. Fondé par le cardinal Lavigerie avec la vision du respect des traditions orientales et de la formation du clergé local, le séminaire a formé plus de 300 prêtres melkites, dont des évêques et patriarches. Ses professeurs ont œuvré pour une meilleure connaissance de l’Orient chrétien, notamment lors du Congrès eucharistique de 1893 à Jérusalem. Le Séminaire a ainsi préparé le terrain pour une nouvelle politique de Rome envers l’Orient. La revue Proche-Orient Chrétien (1951) a marqué l’entrée dans l’œcuménisme authentique. Au Concile Vatican II, l’Église melkite, représentée notamment par d’anciens de Sainte-Anne, a plaidé pour « réserver la place de l’Absent », facilitant le rapprochement avec les Églises orthodoxes. L’auteur suggère que la formation reçue à Sainte-Anne a contribué à cette ouverture œcuménique de l’Église melkite.
Légendes à la base de pèlerinages
Authors: Sicking Thom
Published: July 2024

De nombreux pèlerinages honorent des saints populaires, attirés par des récits légendaires plutôt que par des faits historiques. L’article analyse deux légendes de Saint Georges, le dragon et le martyr, et explore les histoires de la Vierge de San Damiano, ‘Âisha al-Mannûbiyya et cheikh Sha‘rawi. Ces exemples, chrétiens et musulmans, anciens et récents, illustrent la similarité dans la formation des légendes. Elles répondent aux attentes des fidèles et renforcent leur dévotion, indépendamment de leur religion ou de l’époque. L’article met en lumière le rôle crucial des légendes dans la foi populaire, soulignant leur capacité à transcender les frontières du temps et de la religion.
Étude exploratoire sur un leadership empathique
Authors: Pourquier Catherine
Published: July 2024

Cette étude exploratoire porte sur le leadership du prix Nobel de la paix Muhammad Yunus. En nous appuyant sur la littérature et sur des données qualitatives, codées avec Nvivo, nous cherchons à mieux comprendre son leadership. L’angle d’approche de ce papier est la dimension empathique du leadership. La revue de la littérature met en lumière comment l’empathie peut être au service d’un alignement entre les valeurs et l’engagement éthique du leader. L’étude du verbatim constitué d’un entretien personnel avec M. Yunus et de plusieurs entretiens avec ses proches collaborateurs permet de comprendre la spécificité de son leadership empathique. Les résultats de notre étude qualitative exploratoire soulignent la posture « hors norme » du leadership de M. Yunus qui allie notamment des qualités de communication exceptionnelles et une capacité à mettre une pensée intellectuelle en action dans un engagement collectif et altruiste. Notre contribution réside dans un modèle original du leadership de M. Yunus qui montre comment sa dynamique émotionnelle supportée par une forte empathie permet le déploiement d’un leadership multifacette aux compétences particulières basé sur un alignement entre ses valeurs et son engagement.
Proposition d’articulation pratique des théories du bien-être et du mal-être au travail
Authors: Ottmann Jean-Yves
Published: July 2024

Le bien-être et le mal-être au travail sont des notions abordées par de nombreux termes et concepts. Les différents modèles proposent des articulations différentes des deux concepts. Cette diversité conceptuelle et la difficulté à l’articuler est un problème pour les praticiens qui peuvent peiner à se saisir de ces objets. Cet article est une proposition théorique d’articulation de ces champs, à travers un cadre conceptuel destiné à être opérationnel de manière pratique. Il propose un panorama réflexif des champs de littérature qui ont étudié le bien-être et du mal-être au travail puis un modèle théorique capable d’intégrer les modèles conceptuels existants et d’articuler les concepts de bien-être et mal-être au travail entre eux. Dans ce modèle deux éléments disjoints, l’un subjectif et l’autre analytique, sont articulés pour former une matrice conduisant à quatre rapports au travail : le bien-être, le mal-être, le retrait et l’ambivalence. Cet article discute enfin les contributions théoriques mais surtout pratiques de cette conceptualisation proposant ainsi un modèle d’analyse et d’action pour les praticiens.
David Playing for Saul – How Long did Ministers Last During the Portuguese Dictatorship?
Authors: Reis Mourao Paulo
Published: July 2024

Cet article analyse la survie politique des ministres qui ont servi pendant les 48 années de la dictature portugaise (1926-1974). Comme ces hommes politiques ne sont pas confrontés aux défis posés par les cycles électoraux et à la pression des conditions économiques qui affectent le prestige et la longévité des politiciens des démocraties parlementaires, nous avons testé plusieurs autres hypothèses suggérées par la littérature quant à la survie politique dans les régimes autoritaires. Sur la base de l’analyse empirique des fonctions de survie et des régressions à risques proportionnels avec fragilités, nous avons montré que les individus étudiés tendaient à être remplacés plus souvent dans les premières périodes de la dictature quand ils appartenaient à des minorités politiques et que leur opposition au régime était perceptible. En revanche, des facteurs comme de mauvaises perspectives d’emploi, et le fait que des ministres soient jeunes et/ou qu’ils aient servi dans l’armée sont des caractéristiques qui augmentent les chances de survie politique. L’influence d’autres variables sont également examinées, telles que les différences entre les ministères ou les mécanismes et les normes associés à la nomination et à la révocation des ministres.
Entre convergence et disparité. Les SIDS face aux défis de la transition énergétique
Authors: Dimou Michel , Figueiredo De Oliveira Gabriel , Schaffar Alexandra
Published: July 2024

L’objectif de cet article est d’analyser les performances énergétiques des petites économies insulaires en développement (SIDS). Dans un contexte de tensions généralisées sur les marchés énergétiques mondiaux, les SIDS se révèlent des espaces particulièrement vulnérables. En utilisant des données de la Banque Mondiale concernant 183 pays, et en mobilisant des tests de convergence et des méthodes non paramétriques telles que les chaines de Markov, cet article compare les performances énergétiques des SIDS à celles des autres pays. Les résultats indiquent qu’il n’existe pas de convergence absolue entre les pays en termes d’intensité énergétique, mais plutôt une convergence par clubs. Bien que la plupart des SIDS se retrouvent dans les clubs inférieurs ou intermédiaires en ce qui concerne leur intensité énergétique, leurs performances en termes de réduction de cette intensité énergétique entre 2000 et 2019 sont parmi les plus faibles.
Mécanismes de sécurisation des revenus pour les travailleurs précaires et qualité des relations sociales : une étude expérimentale
Authors: Couprie Hélène , Peterle Emmanuel , Tisserand Jean-Christian
Published: July 2024

Cet article relate les résultats d’une expérience économique simulant le fonctionnement d’un marché du travail dual. L’économie, stylisée, est présentée aux participants de manière contextualisée, mettant en scène des travailleurs « permanents » et « temporaires » collaborant de façon répétée, pour produire un bien public au sein d’entreprises. Nous comparons les contributions des travailleurs « permanents » et « temporaires » et mesurons l’impact de la mise en place de mécanismes visant à sécuriser le revenu des travailleurs précaires (assurance chômage, prime de précarité) sur la contribution de ces derniers au bien public, ainsi que sur la confiance interpersonnelle. La présence de travailleurs temporaires et permanents n’affecte pas la performance globale de notre économie ni la propension moyenne à contribuer pour le bien public. Bien que la diminution des inégalités puisse en théorie favoriser un environnement propice à la coopération, l’application de ces mesures, notamment via l’imposition de taxes ou l’introduction de primes à destination exclusive des travailleurs précaires, altère les incitations individuelles à contribuer. Nous constatons ainsi que les mesures de sécurisation des revenus pour les travailleurs précaires tendent à affaiblir les comportements de coopération dans notre cadre expérimental. Nous observons aussi que les participants accordent davantage leur confiance aux travailleurs permanents qu’aux travailleurs temporaires.
