Digital transformation in education has created the need to train teachers and improve their digital competencies. However, training processes are often ineffective due to the lack of personalization in the proposals and the variety in teacher profiles. Given this, this article addresses the development of a web tool designed to diagnose teachers’ digital competencies and provide personalized recommendations for MOOCs to support the development of their skills. To achieve this, a system that uses Natural Language Processing (NLP) techniques and a content-based recommendation model is proposed. Course data is obtained through web scraping and processed with NLP techniques, using an advanced language model (BERT) to generate vector representations of the courses and competencies. The web system allows teachers to self-assess their competencies, visualize the results, and receive personalized recommendations for MOOCs. The implementation of this system has proven effective in identifying teachers’ areas for improvement and suggesting relevant courses for their professional development. The results suggest that the use of this system can be an effective solution for training teachers in digital competencies.

The way people learn has undergone a significant transformation thanks to the advancement of technology. Various digital tools complement daily and academic activities, facilitating access to updated and diverse information. The Internet, in particular, has positioned itself as the primary source of information, offering a large amount of textual and audiovisual content, with short content in the form of videos being the most popular. However, the learning process inevitably involves acquiring new concepts and terms. When encountering unfamiliar vocabulary in videos, people often search for additional information to understand the content better. Therefore, this research seeks to develop a tool capable of analyzing video transcripts using Natural Language Processing techniques to identify key terms and relate them to other relevant information sources, thus facilitating learning. When evaluating the relevance of terms to the textual content of videos on various topics using an Artificial Intelligence model, a relevance greater than 75% was evidenced for all terms. This confirms the efficacy of this approach for analyzing and understanding the textual content of transcribed videos.

Cyberbullying has a negative impact on society due to the consequences suffered by victims, bullies, and bystanders. Widespread access to the internet and social networks, especially among young people without the tools to deal with these situations, makes social education necessary to mitigate the effects of cyberbullying. This study seeks to contribute to this training through the creation of scripts for educational capsules. To this end, a model was developed that automates the search and extraction of data from the social network X using Python and Selenium Web Driver. After a text preprocessing process using Natural Language Processing techniques, the Latent Dirichlet Assignment (LDA) model was applied to identify keywords. Finally, the pre-trained model "text-davinci-003" was used through the OpenAI API to generate the content of the educational capsules, assigning a context and using the identified keywords. The outcome of this proposed research is the generation of a script that includes topics on education and the prevention of bullying and cyberbullying. To ensure the reliability of the text generated by the pre-trained generative model, it was evaluated by an expert in the field using the Goal-Question-Metric (GQM) approach, which validates its potential in generating educational content in the fight against cyberbullying.

In international trade, choosing the ideal supplier can be a challenge. Against this background, it is mandatory to identify the countries from which the import of a certain good is most appropriate. Therefore, this paper proposes a model that allows for the analysis and visualization of cost data for imports into Ecuador from 2008-2018. To achieve this, the existing information on imports was analyzed by reviewing the related literature. Then, the K-means algorithm was applied to group countries by tariff heading, considering the FOB value and import costs. Finally, a visualization interface facilitates decision-making based on the obtained information. Consequently, the proposed model is useful for decision-making in imports because it allows data analysis from all countries in conjunction with imported goods, proving to be applicable to a wide range of companies.

Published: October 2024

This case study describes and analyzes the integration of AI-generated avatars as communication tools in educational videos within Massive Open Online Courses (MOOCs). Various aspects were analyzed: the acceptance of the avatar as a communication medium, the credibility and empathy conveyed by it, the retention of attention throughout the videos, and its contribution to conveying the message clearly and understandably. A quantitative descriptive analysis and qualitative analysis of surveys completed at the end of the course were conducted. The preliminary descriptions suggest that AI-generated avatars could function as substitutes for human recordings to convey information. Greater refinement of the technology and further efficacy studies on knowledge conveyance and cost-effectiveness are still required to determine the advantage of this technology compared to traditional recordings.

Мақалада рапс дақылының вегетативті мүшелері жапырақ зиянкестеріне қарсы күресу шараларын ұйымдастырудың негіздері қарастырылған. Далалық тәжірибелер 2022-2024 жылдары Жамбыл облысы, Т.Рысқұлов ауданының  «Берік » ШҚ -да жүргізілді. Зерттеудің негізгі нысаны ретінде рапстың аудандастырылған Юбилейный, Циклон, Ратник, Форум, Сибник сорттары таңдалды. Дақылдың зиянды ағзаларымен күресу шаралары кезінде  химиялық препараттар: авант, к.э. 0,2 л/га, аскум, к.э. 0,2л/га, стабилити, к.э. 0,8, лятрин, к.э. 0,1л/га. сыналды.
Рапс дақылының тұқымын  күнделікті өңдеу жұмыстарын жүргізу оларды аурулар мен зиянкестерден қорғауға мүмкіндік береді. Біздің зерттеу жүргізген аймақта рапс дақылының жапырағын зақымдайтын, ең көп залал келтіретін зиянкестер деп крест тәрізді бүргелерді, рапс егеушісін, қырыққабат және крестгүлділер ақ көбелегін, қырыққабат құрты және крест тәрізді бітелерді анықтадық.
Жоғарыда аталған барлық сыналған препараттар жоғары биологиялық тиімділікті, яғни, 80-83 % - 5а дейінгі көрсеткішті көрсетті. Зиянкестердің (крест тәрізді бүргелер, рапс егеушісі, қырыққабат және крестгүлділер ақ көбелегі, қырыққабат құрты және крест тәрізді бітелер) саны да күрт төмендеді. Рапс тұқымдары мен дақылында сыналған препараттармен өңдеу осы дақылдың жапырақ зақымдайтын зиянкестердің зақымдануын азайтуға көмектеседі деген тұжырымға келдік.

Бидай еліміздің экономикалық маңызды өнімдерінің бірі. Қазақстан бидайды өндіру және экспорттау бойынша алдыңғы қатарлы мемлекеттердің қатарына кіреді.  Бидайдың қоңыр тат ауруы оның өнімділігіне тікелей әсер ететін аурулардың бірі. Қоңыр тат ауруы бидайдың жапырақтарында ғана пайда болуына байланысты жапырақтың қоңыр таты деп те аталады. Аурудың қоздырғышы Puccinia triticina саңырауқұлақтары. Жапырақтың қоңыр таты ауруы саңырауқұлақ ауруы болып табылатындықтан, саңыруқұлақтардың жаңа штаммдарды қалыптастыра білу қабілетінің арқасында тат ауруы бұрын соңды ауруға төзімді болған сорттарға да зиян келтіруі мүмкін.  Бидайға ауру жұғу үшін аздаған жаңбыр да жеткілікті. Бидайдың гүлдену кезеңінің алдында жапырақты тат өсімдікке айтарлықтай зиян келтіреді. Залалданған саңырауқұлақтар бидайдың жапырағында пайда болатын, дәннің қалыптасуына қажет қоректік заттарды пайдаланады, нәтижесінде бидайдың жапырақтары ерте түсіп, дәнге қоректік заттар жетіспегендіктен дән дұрыс қалыптаспайды, бидай өнімділігі азаяды. Осы себептерге байланысты қоңыр тат ауруына төзімді сорттарды анықтау экономикалық маңызды. Зерттеу объектісі ретінде алынған 30 күздік бидай сорттарын қоңыр татқа Puccinia triticina төзімділігін фитопатологиялық зерттеу және олардың өнімділік элементтеріне құрылымдық талдау жүргізудің нәтижесінде қоңыр татқа төзімділігі және шаруашылық құнды белгілері бойынша Alatau, Alikhan, Almaly, Kyzylbiday, Mayra, Mereke 70, Naz, Raminal, Rasad, Sapaly және Tyngysh сорттары жоғары көрсеткіштер көрсетіп ерекшеленді.

Published: October 2024

This research paper contributes to the regulation of surrogacy in Ecuador, a controversial topic that has gained attention in scientific and social circles. Although the practice is not legally regulated, there has been an increase in discussion and interest in this topic in the country. The objective is to examine the Ecuadorian regulations and jurisprudence applicable to the regulation of surrogate motherhood considering ethical and social principles. It was based on a historical, normative and jurisprudential study. The qualitative methodology was applied, by means of the empirical analytical method that allowed analyzing the opinions of experts in family law, human rights and bioethics, and evaluating how surrogate motherhood would be integrated within the existing legal framework in Ecuador, which requires further research and an informed debate to structure a legal and ethical framework that regulates surrogate motherhood in Ecuador. We were able to conclude the potential impact that surrogacy has in terms of equity and reproductive justice, as well as in the integral protection of the rights of all parties involved. However, it must be recognized that this discussion must encompass a variety of perspectives, including the opinions of experts in bioethics, reproductive medicine and psychology.

Among males over 65, up to 30% may experience problematic LUTS.  Objectives of the Study The aim of this study is to determine the prevalence and risk factors contributing benign prostate hyperplasia among elder patients in Baidoa hospitals in Somalia.  Materials and Methods The study design was a hospital based cross sectional study.  Results The prevalence of BPH shows that 19.01 % of the participants were becomes BPH while the remaining majority 80.99 was not. The age, the largest group is those aged 70-79 years, with 157 participants, representing 40.9%. In terms of family history of (BPH), 310 participants (80.7%) reported no family history, while 74 individuals (19.3%) indicated that they do have a family history of BPH. Examining systemic diseases, 51 participants (13.2%) have diabetes mellitus, and 67 individuals (17.3%) have hypertension. A smaller subset, 26 participants (6.7%), reported having both diabetes and hypertension. Regarding physical exercise, 310 individuals (80.7%), reported not engaging in regular physical activity, while only 74 participants (19.3%) they do exercise.  Conclusion In summary, the data and reports from this study point to a 19.01% prevalence of benign prostatic hyperplasia (BPH). The development of BPH is significantly predicted by age. Bivariate chi-square analysis revealed a significant link between BPH and erectile dysfunction, kidney illnesses, diabetes mellitus, and urine retention (p-value <0.05). On the other hand, bivariate chi-square analysis revealed a significant relationship between BPH and being overweight and frequently consuming caffeine (p-value <0.05). Diet and lifestyle could be factors in this.  Recommendations Lifestyle and behavioral interventions are reasonable first-line treatments for all patients. Straightforward interventions include limiting intake of the following: fluids prior to bedtime or travel; mild diuretics, such as caffeine and alcohol; and bladder irritants, such as highly seasoned or irritative foods. Older be aware that blocking of the urethra (the urine tube): As the prostate grows larger, it may block the bladder outlet and stop the bladder from emptying. In some cases, urine may get stored up until it starts to leak out. If this happens, see a doctor straight away, so the patients should urinate quickly before experiencing any problem.

The formation of the massive stars, and in particular, the role that the magnetic fields play in their early evolutionary phase is still far from being completely understood. Here, we present the Atacama Large Millimeter/submillimeter Array 1.2 mm full polarized continuum and H13CO+(3−2), CS(5−4), and HN13C(3−2) line observations with a high angular resolution (∼0.″4 or 1100 au). In the 1.2 mm continuum emission, we reveal a dusty envelope surrounding the massive protostars, IRAS16547-E and IRAS16547-W, with dimensions of ∼10,000 au. This envelope has a biconical structure likely carved by the powerful thermal radio jet present in region. The magnetic field vectors follow very well the biconical envelope. The polarization fraction is ∼2.0% in this region. Some of these vectors seem to converge to IRAS 16547-E and IRAS 16547-W, the most massive protostars. Moreover, the velocity fields revealed from the spectral lines H13CO+(3−2) and HN13C(3−2) show velocity gradients with a good correspondence with the magnetic fields, which maybe are tracing the cavities of molecular outflows or maybe infalling in some parts. We derived a magnetic field strength in some filamentary regions that goes from 2 to 6.1 mG. We also find that the CS(5−4) molecular line emission reveals multiple outflow cavities or bow shocks with different orientations, some of which seem to follow the NW–SE radio thermal jet.

We present initial results associating galaxies in the Multi-Unit Spectroscopic Explorer (MUSE) Ultra Deep Field (MUDF) with gas seen in absorption along the line of sight to two bright quasars in this field to explore the dependence of metals in the circumgalactic medium (CGM) on galaxy properties. The MUDF includes ∼140 hr of Very Large Telescope (VLT)/MUSE data and 90 orbits of Hubble Space Telescope (HST)/G141M grism observations alongside VLT/Ultraviolet and Visual Echelle Spectrograph spectroscopy of the two quasars and several bands of HST imaging. We compare the metal absorption around galaxies in this field as a function of impact parameter, azimuthal angle, and galaxy metallicity across redshifts 0.5 < z < 3.2. Due to the depth of our data and a large field of view, our analysis extends to low stellar masses (<107
M
⊙) and high impact parameters (>600 kpc). We find a correlation between the absorber equivalent width and the number of nearby galaxies, but do not detect a significant anticorrelation with the impact parameter. Our full sample does not show any significant change in absorber incidence as a function of azimuthal angle. However, we do find a bimodality in the azimuthal angle distribution of absorption at small impact parameters (<2 r
vir) and around highly star-forming galaxies, possibly indicating disk-like accretion and biconical outflows. Finally, we do not detect any systematic deviation from the fundamental metallicity relation among galaxies with detected absorption. This work is limited by gaps in the wavelength coverage of our current data; broader-wavelength observations with the James Webb Space Telescope will allow us to unlock the full potential of the MUDF for studying the CGM.
Relationship between the Tilt Angles of Sunspot Groups and the Properties of the Next Solar Cycle
Authors: Gao P. X. , Xu J. C.
Published: October 2024

Based on the data from the Kodaikanal and Mount Wilson observatories, we investigate the relationships of the tilt angles of sunspot groups, including the mean tilt angle and the tilt-angle scatter, during the declining phase with the parameters of the next solar cycle (SC). The main findings are summarized in the following three points. (1) During the declining phase, the correlation between the mean tilt angle and the tilt-angle scatter is statistically insignificant. (2) Six quantities measured during the declining phase show significant anticorrelations with the strength and amplitude of the next SC and positive correlations with the duration of the ascending phase of the next SC: the standard deviation of the tilt angles, the rms tilt angle, the mean absolute value of the tilt angles, the area-weighted absolute value of the tilt angles, the latitude-weighted absolute value of the tilt angles, and the area- and latitude-weighted absolute value of the tilt angles. (3) The correlations of the mean tilt angle, the area-weighted tilt angle, the latitude-weighted tilt angle, and the area- and latitude-weighted tilt angle during the declining phase with the strength, amplitude, and duration of the ascending phase of the next SC are statistically insignificant. These findings demonstrate that the modulation of the parameters of the next SC by the tilt-angle scatter during the declining phase plays a vital role in regulating SC variability.

⊙ in the globular star clusters of NGC 1399 at a frequency of 300.00 MHz. Employing the theoretical Bondi accretion model and the empirical fundamental plane (FP) of black hole accretion, we estimate IMBH masses based on bolometric luminosity and X-ray/radio luminosities, respectively. By simulating a 3 hr observation of 77 globular cluster (GC) candidates using the Square Kilometre Array, we identify radio detection benchmarks indicative of accretion onto IMBHs. Our results show that IMBHs inside the globular star clusters located in NGC 1399 are indeed detectable, with the Bondi accretion model providing IMBH mass estimates ranging from 2.93 × 103.0±0.39

Constraining Ocean and Ice Shell Thickness on Miranda from Surface Geological Structures and Stress Modeling
Authors: Strom Caleb , Nordheim Tom A. , Patthoff D. Alex , Fieber-Beyer Sherry K.
Published: October 2024

Images from the Voyager 2 mission revealed the small Uranian satellite Miranda to be a complex, dynamic world. This is exemplified by signs of recent geological activity, including an extensive fault system and the mysterious coronae. This has led to speculation that Miranda may have been tectonically active within the geologically recent past and could have hosted a subsurface liquid water ocean at the time. In this work, we aim to constrain the thickness ranges for the ice shell and potential subsurface ocean on Miranda. Here, we present the results for our geological mapping of craters, ridges, and furrows on the surface. We also present the results for our comparison of the geographic distribution of these features to the predicted geographic distribution of maximum tidal stress based on stress models. We model eccentricity tidal stress, ice shell thickening stress, true polar wander stress, and obliquity tidal stress and compare the predicted surface stress pattern for each to what pattern can be inferred from the surface geology. Our results show that a thin crust (≤30 km) is most likely to result in sufficient stress magnitude to cause brittle failure of ice on Miranda’s surface. Our results also suggest the plausible existence of a ≥100 km thick ocean on Miranda within the last 100–500 million yr. This has implications for the dynamical history of Miranda and its status as a potential ocean world.

A pressure-robust divergence free finite element basis for the Stokes equations
Authors: Chu Jay , Hu Xiaozhe , Mu Lin
Published: October 2024

This paper considered divergence-free basis methods to solve the viscous Stokes equations. A discrete divergence-free subspace was constructed to reduce the saddle point problem of the Stokes problem to a smaller-sized symmetric and positive definite system solely depending on the velocity components. Then, the system could decouple the unknowns in velocity and pressure and solve them independently. However, such a scheme may not ensure an accurate numerical solution to the velocity. In order to obtain satisfactory accuracy, we used a velocity reconstruction technique to enhance the divergence-free scheme to achieve the desired pressure and viscosity robustness. Numerical results were presented to demonstrate the robustness and accuracy of this discrete divergence-free method.
Spanish participation in the social science and humanities research projects within the 7th European Union Framework Programme (2007-2013)
Authors: Ardanuy Jordi , Sulé Andreu , Borrego Ángel
Published: October 2024

The objectives of this paper are to describe the Social Science and Humanities projects involving Spanish participation within the Seventh EU Framework Programme (FP7) (2007-2013), along with the scholarly output generated by these projects, and to compare the findings with the data from FP6 (2002-2006) in order to track their evolution. First, we determine the most significant characteristics of the projects with Spanish participation (duration, funding, topics, type of institution, etc.). Second, we analyse the scholarly production derived from a sample of projects taken from the Scopus database to analyse some bibliometric features. The results show an increase in the leadership and prominence of Spanish institutions, compared to FP6-SSH. In terms of scholarly outputs, none of the sources used (CORDIS, OpenAIRE and SCOPUS) allows a detailed study of scholarly production, although this output is characterized by articles written predominantly in English, published in first-quartile journals. Moreover, data showed that research funding for SSH may have long-term effects, with some outputs acknowledging funding being published a decade after the end of the project.
Aplicación de indicadores bibliométricos en el diseño y evaluación de la estrategia de especialización territorial Caso de Andalucía
Authors: Docampo Domingo , Luque-Martínez Teodoro , Faraoni Nina , Doña-Toledo Luis
Published: October 2024

La estrategia europea de especialización inteligente RIS3 postulaba la especialización del territorio. Dicha especialización debiera estar asociada con la producción científica. Distinguiendo dos períodos (2010-2016 y 2017-2023), este trabajo comprueba la idoneidad de la RIS3 definida por Andalucía con indicadores bibliométricos de su producción científica, así como los efectos de la implementación de dicha estrategia considerando los indicadores del segundo período, identificando puntos fuertes y débiles en la producción científica, en general creciente, para las ocho áreas definidas. Los indicadores de Recursos endógenos y Turismo-cultura-ocio avalan la especialización, tanto al principio como tras la implementación; Salud-bienestar social y TIC-economía digital no presentaban indicadores que avalaran la especialización, pero mejoraron mucho en calidad; otros campos no destacaban y empeoraron: Movilidad y logística e Industria del transporte, siempre en comparación con resto de España y Europa. Se analiza la eficacia de RIS3-Andalucía, destacando aspectos multifacéticos de la especialización científica y su impacto.
An analytical framework for the study of geographical places in the scientific literature
Authors: Orduña-Malea Enrique , Miguel Sandra , González Claudia M. , Arias Romina R. , Ortiz-Jaureguizar Edgardo
Published: October 2024

Scientometrics has traditionally examined place in terms of author affiliations and, as such, has tended to overlook the more detailed use of geographical data in scholarly publications to design indicators of the scientific literature. This study constructs a comprehensive framework to formalize and unify the Scientometrics analysis of places (Spatial Framework to identify Bibliographic Relationships or SFBR), constituting three main stages: identification, description, and measurement. We present five descriptive dimensions and a set of 57 core metrics for scrutinizing the place-related features of science. These metrics encompass author-, publication-, and place-level parameters, categorized according to the specific section (zone) containing the geographical information (i.e., citing author affiliation, the body of the text, and cited author affiliation). The SFBR serves as an innovative tool for unraveling the significance and influence of place in scientific literature. By considering place a fundamental element in Scientometrics studies, it extends the boundaries of spatial bibliometrics and provides a more holistic understanding of place as research object.
Datos abiertos de investigación en repositorios universitarios españoles
Authors: Monteagudo-Haro Pablo , Prieto-Gutierrez Juan Jose
Published: October 2024

Se analiza la situación actual de los datos de investigación abiertos en los repositorios de las universidades españolas a través de doce indicadores que permiten compararlos entre sí. Los doce indicadores de elaboración propia tratan sobre los conjuntos de datos de investigación y las políticas institucionales vinculadas al acceso abierto, además de algunas de las características claves de los repositorios. La metodología que se lleva a cabo consiste en la comparación entre repositorios de las diferentes universidades vinculadas a REBIUN. El resultado ha sido que los conjuntos de datos en repositorios institucionales son escasos, y la situación es heterogénea en todo el territorio. Esto lleva a plantear cuestiones sobre cuáles van a ser las futuras políticas de acceso abierto sobre los datos de investigación en las principales instituciones científicas del país.
Effets des encouragements sur l’engagement des élèves en demi-fond : une méthode mixte de recherche fondée sur l’articulation de données de vitesse et d’expérience
Authors: Montois Thomas , Müllenheim Pierre-Yves de , Terré Nicolas
Published: October 2024

Cette étude s’est attachée à analyser les effets d’encouragements sur l’engagement d’élèves dans une situation de course de demi-fond en EPS, par l’articulation de données quantitatives (vitesse de course recueillie par des récepteurs GPS) et qualitatives (expériences documentées à partir d’entretiens d’auto-confrontation). Les données ont été combinées dans des frises expérientielles. Par cette méthode, nous avons identifié des variations de vitesse significatives et différentes en termes d’intensité et de durée. Les expériences associées ont permis de mettre en évidence que l’apprenant est susceptible : (i) d’accélérer après un encouragement qui le met en confiance ou qui est signifiant pour lui ; (ii) de ralentir après un encouragement pour cause de douleur ou par anticipation d’un effort futur ; et (iii) d’accélérer sans être encouragé par autrui mais par soi-même ou en encourageant les autres. Tout en supportant l’intérêt des méthodes mixtes de recherche (MMR), ces résultats montrent l’importance des encouragements en EPS et l’intérêt d’éduquer les élèves à s’en saisir et en prodiguer eux-mêmes.

Il donne également un aperçu du travail effectué par l'Association transdisciplinaire pour les recherches historiques sur l'éducation (ATRHE), fondée en 2011, pour assumer la pluralité des appartenances disciplinaires des chercheurs en histoire de l’éducation et stimuler de nouvelles dynamiques de recherche.
Le spectre de l’histoire de la pédagogie en France
Authors: Riondet Xavier
Published: October 2024

L’histoire de la pédagogie constitue en France une tradition d’intervention et de publication très ancienne dans les sciences de l’éducation et de la formation. Cet article se propose de revenir sur la spécificité de cette historiographie dans le champ de l’histoire de l’éducation et sur ses évolutions au sein de cette discipline universitaire, en s’intéressant à trois moments différents : la science de l’éducation sous la IIIe République, les premières années de l’institutionnalisation des sciences de l’éducation à partir de 1967 et la période contemporaine.
La réception du Code pénitentiaire au regard du droit européen
Authors: Larralde Jean-Manuel
Published: October 2024

Le Code pénitentiaire constitue un instrument juridique important de mise en œuvre, ou tout du moins un commencement de mise en œuvre, de plusieurs principes fondamentaux qui permettent de renforcer les droits et la protection des personnes détenues par l’amélioration du principe de sécurité juridique. Cet apport positif est probablement moins évident concernant d’autres principes directeurs dégagés par la Cour de Strasbourg, tels que les principes de dignité et de vulnérabilité.
Le travail en détention
Authors: Fin-Langer Laurence , Gabroy Fanny
Published: October 2024

Le Code pénitentiaire, entré en vigueur le 1er mai 2022, constitue une réelle avancée en ce qui concerne le statut du travailleur pénitentiaire, qui se rapproche de celui du travailleur de droit commun, tout en étant adapté au milieu carcéral. Mais cette réforme peine à remplir un objectif pourtant clairement affiché, à savoir l’insertion sociale et professionnelle du détenu.
La dignité humaine, une liberté fondamentale au sens du référé-liberté ?
Authors: Tamion Anna
Published: October 2024

Le juge administratif établit la liste des libertés fondamentales au sens de l’article L. 521-2 du Code de justice administrative, relatif à la procédure de référé-liberté, et il n’est pas certain que la dignité humaine fasse partie de cette catégorie. L’étude de la jurisprudence révèle une hésitation du juge à consacrer la dignité humaine comme une liberté fondamentale au sens de l’article L. 521-2 du Code de justice administrative. Cette réserve pourrait s’expliquer par une prudence libérale mais aussi des considérations pratiques.
Écologiser sans contester : le travail politique autour de deux éco-innovations dans l’aquaculture canadienne
Authors: Police Antoine
Published: October 2024

L’économie canadienne constitue un cas paradigmatique d’exploitation intensive des ressources naturelles. Depuis plusieurs décennies, ce modèle est contesté par de nouveaux acteurs environnementaux qui peinent à changer les logiques de production. En s’appuyant sur des approches renouvelées de l’écologisation issues de la sociologie politique, ce papier propose d’analyser un mode d’écologisation alternatif à la contestation : l’implémentation d’innovations écologiques (ou éco-innovations). L’étude de ce processus est opérationnalisée dans deux études de cas issues de l’aquaculture canadienne. L’analyse du travail de construction et de promotion de deux éco-innovations permet de montrer les trajectoires d’une écologisation discrète entre science et industrie.
Résistances littéraires au capitalisme gore : Cristina Rivera Garza et Sayak Valencia
Authors: Palaisi Marie-Agnès
Published: October 2024

Cet article s’ouvre sur une explicitation de la situation de violences systémiques dans laquelle se trouve le Mexique depuis le milieu des années 90 avec une intensification à partir de 2006 à partir de l’analyse que Sayak Valencia en propose dans son essai Capitalismo gore. Ensuite, il s’agit de présenter les résistances à cette nécro-politique que les écrivaines mexicaines travaillent dans leurs fictions. Je m’arrêterai sur deux types antagoniques de propositions littéraires : je présenterai tout d’abord les apports de la nécro-écriture portée par Cristina Rivera Garza, puis je reviendrai à Sayak Valencia par ses écrits fictionnels pour étudier l’utopie cuir qu’elle construit dans sa poésie et la réponse que celle-ci constitue au capitalisme gore.
