Abstract. Soil organic carbon (SOC) stabilization and destabilization has been studied intensively. Yet, the factors which control SOC content across scales remain unclear. Earlier studies demonstrated that soil texture and geochemistry strongly affect SOC content. However, those findings primarily rely on data from temperate regions where soil mineralogy, weathering status and climatic conditions generally differ from tropical and subtropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1601 samples were analyzed, collected from two depths (0–20 and 20–50 cm) from 17 countries as part of the Africa Soil Information Service project (AfSIS). The data set spans arid to humid climates and includes soils with a wide range of pH values, weathering status, soil texture, exchangeable cations, extractable metals and land cover types. The most important SOC predictors were identified by linear mixed-effects models, regression trees and random forest models. Our results indicate that geochemical properties, mainly oxalate-extractable metals (Al and Fe) and exchangeable Ca, are equally important compared to climatic variables (mean annual temperature and aridity index). Together, they explain approximately two-thirds of SOC variation across sub-Saharan Africa. Oxalate-extractable metals were most important in wet regions with acidic and highly weathered soils, whereas exchangeable Ca was more important in alkaline and less weathered soils in drier regions. In contrast, land cover and soil texture were not significant SOC predictors on this large scale. Our findings indicate that key factors controlling SOC across sub-Saharan Africa are broadly similar to those in temperate regions, despite differences in soil development history.

Estos investigadores proponen que el cultivo racional de los suelos amazónicos junto con la efectividad de su producción y la conservación del ecosistema son una alternativa a un sistema de cultivo permanente que rompería la estabilidad ecológica y económica que han logrado los nativos del Amazonas.
Demuestran, a través de su experiencia con el pueblo nativo de Bora, que, a través de un sistema de agricultura transmitido a través de su tradición cultural, el abandono de sus campos es parte de un período natural y progresivo dentro del ecosistema.
Las sociedades indígenas de la selva tropical utilizan un sistema de cultivo en barbecho como medio natural de relacionarse con el hábitat amazónico, como parte de un ciclo que comienza con el cultivo y termina con un período de barbecho. La abonificación de los campos, en este sentido, no es un descuido de la tierra, sino un proceso natural y consciente.

Characteristics of Saudi EFL Learners’ Learning Styles
Authors: Al-Seghayer Khalid 
Published: June 2021

One of the most important factors among those that play key roles in second language acquisition is language learning styles and strategies. This article identifies the unique and multifarious learning-style preferences that characterize Saudi English as a foreign language (EFL) learners&rsquo; learning, and explores how multidimensional causal factors and experiences shape their preferred modes of learning. The analysis first tackles Saudi EFL learning-style preferences, followed by a discussion of Saudi EFL language learning strategies. The discussion addresses the learning-style approaches and learning behaviors of Saudi EFL leaners and the impact they have on them and highlights the factors and consequences of each. It concludes by pinpointing the importance of identifying language learning styles and strategies Saudi EFL students use and offering measures that will help Saudi EFL teachers facilitate their students&rsquo; effective learning-style approaches.

Developmental trajectories of hackers: a longitudinal study of defacements on Dutch websites
In this study we examined the developmental trajectories of hackers, based on their self-reported web defacements. During a web defacement, the content of a website is altered without permission. In total, 50,330 defacements of websites with a Dutch extension (.nl websites) were analyzed, which were executed by 3,640 defacers between January 2010 and march 2017. Using trajectory analysis, six different groups of defacers could be distinguished: two chronic groups of attackers and four groups who only defaced websites during a limited time period. These groups also differed in their motivations and modus operandi. The high frequent chronic attackers consist of less than 2% of the hackers, but were responsible for more than half of all defacements. It would therefore be most efficient when future interventions focus on this small group of chronic offenders. For future studies it would be an interesting topic to examine the content of the web defacements.

Impressionism and Imperialism in Maurice Cullen’s African River
Authors: Young Marnin 
Published: June 2021

Maurice Cullen (1866-1934) a longtemps été considéré comme le point d’origine de l’impressionnisme canadien. « Où » se trouve ce point, cependant, reste une question ouverte. Pour les critiques des années 1890, ses peintures étaient clairement « françaises ». Plus tard, Arthur Lismer et d’autres les ont vues comme l’incarnation de « l’esprit canadien ». Cullen a-t-il ainsi importé un style français ou en a-t-il cultivé un typiquement canadien ? L’auteur affirme que les premières oeuvres du peintre problématisent déjà, dans leur production même, ce dérèglement du lieu. Son argumentaire repose sur une analyse d’African River de Cullen, un tableau de 1893 qui représente la ville algérienne colonisée de Biskra. Dans sa combinaison de la technique impressionniste française et de l’iconographie impérialiste française, cette peinture « canadienne » se présente comme un cas typique révélant les contradictions spatiales inhérentes à l’impressionnisme mondial. Le tableau gère la contradiction, peut-on lire dans cet essai, en combinant deux manières distinctes, bien qu’imbriquées, de conceptualiser l’espace lui-même : phénoménologique et géopolitique.
Satire et sociabilité au coeur de la pratique caricaturale de Lady Dalhousie (1786-1839) : vers une histoire des femmes caricaturistes britanniques
Authors: Ferron-Desautels Marie 
Published: June 2021

In 1987, the archivist Marie Elwood published a paper discussing her research in Scotland, which led to the repatriation of Lord Dalhousie’s collection and the discovery of five caricatures painted by Lady Dalhousie during her Canadian sojourn from 1816 to 1828. Since then, nothing has been written on the subject matter, the humour, and the sociability that these caricatures involved, a lack this paper aims to fill. What was the target of Dalhousie’s satirical gaze? Was it common for an aristocratic woman such as Dalhousie to paint caricatures? In order to provide answers to these questions, I will examine the caricatural strategies employed by Lady Dalhousie as well as her satirical perspective. Finally, I will consider the sociability that surrounded the display of these images by relating Dalhousie to other British women who contributed to the creation and the circulation of caricatures during the eighteenth and nineteenth centuries.
Mariama Bâ et Djaïli Amadou Amal : Une si Longue Lettre des (Im)patientes
Authors: Tchokothe Rémi Armand 
Published: June 2021

Cette contribution « Mariama Bâ et Djaïli Amadou Amal : Une si Longue Lettre des (Im)patientes » relit/relie le classique Une si longue lettre (1980) de la Sénégalaise Mariama Bâ à travers le prisme de l’inter-actualité avec Les Impatientes (2020) de la Camerounaise Djaïli Amadou Amal. Nous mettons l’accent sur les synergies 1. Philosophico-lexicale (des mots du pulaaku sur les maux de la polygamie). 2. D’itinéraire littéraire. 3. Narratologique (voix et voies des (im)patientes) et 4. Stylistique (lettre contée munyalement comme thérapie libératrice et émancipatrice). Nous insistons néanmoins sur Les Impatientes car on ne compte plus les travaux publiés sur Une Si Longue Lettre, alors qu’on ne trouve que quelques entretiens dans les médias avec Djaïli Amadou Amal. Cet article s’appuie sur une philosophie/théorie proposée par Les Impatientes pour étudier le statu quo sur le sort des femmes dans deux contextes musulmans, le Munyal (« patience »). Par ailleurs, il contribue à la constitution d’un corpus critique sur l’œuvre d’une voix littéraire féminine émergente au Cameroun.
Logogriphes. Réflexions sur l’illisibilité des corps comme stratégie politique
Authors: Ségard Arthur 
Published: June 2021

Après avoir établi que le corps s’inscrit dans un système de signification, cet article propose une analyse diachronique de plusieurs corps qui ont été perçus ou se sont présentés comme « illisibles » : le corps de Vellini, femme indépendante et mystérieuse au cœur du roman Une vieille maîtresse de Barbey d’Aurevilly, le corps des « monstres et prodiges » observés par Ambroise Paré au XVIe siècle, et le corps du philosophe Paul B. Preciado, qu’il place au cœur de sa démarche théorique et politique depuis 2005. Parce qu’ils échappent aux structures sociales qui cherchent à les interpréter, à les classifier ou à les normaliser, ces corps ont tous été qualifiés de monstrueux. En mettant en évidence l’origine sociale de cette désignation, cet article interroge les usages politiques possibles de cette « illisibilité », et notamment sa réappropriation par des groupes marginalisés.
Quand les applications mobiles s’invitent dans la fiction : la littérature gay « grindrisée »
Authors: Fraissard Florian 
Published: June 2021

Nous nous proposons d’étudier le lien entre littérature et nouvelles technologies à travers la question de l’intégration des applications mobiles au sein de la création littéraire gay des années 2010. L’image et le fantasme occupent une place prépondérante au sein de cette nouvelle technologie. Leur insertion dans le champ littéraire conduit à redéfinir les rapports à l’image, à soi et à la fiction littéraire. Les applications semblent donc être un facteur de mutabilité textuelle dans la mesure où elles modifient un certain nombre de codes littéraires faisant de la littérature gay un espace « grindrisé ».
Les mutations des relations entre auteurs et éditeurs littéraires à l’ère du numérique : une crise de l’autorité ?
Authors: Boutoux Corentin 
Published: June 2021

Depuis l’apparition de la figure moderne de l’éditeur au début du XIXème siècle, la nature des relations entre les auteurs et le champ de production des œuvres littéraires a été le fruit d’innombrables débats. Entre le créateur et celui qui transforme l’œuvre en produit commercialisable, qui détient quelle autorité ? La transformation de l’édition en industrie culturelle semble avoir relégué l’auteur à la seconde place et l’avoir inscrit dans une longue histoire de domination, tout en étant l’instigateur de sa légitimité et le moteur de sa reconnaissance. Le développement de l’informatique et des technologies numériques entraîne de nouvelles mutations du marché du livre. Alors que les acteurs institués adoptent progressivement le recours à ces nouveaux outils pour entériner leur domination, des circuits parallèles se mettent en place, à la périphérie du pouvoir. A l’heure actuelle, que devient le rapport de cet auteur à ces constructions instituées ? Sa place est-elle renégociée ?
